Hello everyone, My new laptop Thunderobot Zero 11800H_RTX3060 have a locked bios. I tried CPU undervolt via ThrottleStop utility and Intel XTU utility, but they didn't work. I heard I need to unlock advanced settings in BIOS to unlock these utilities. So, I need help to unlock hidden advanced settings. Thanks!

For those who don't like the restrictions Lenovo put on their system, here's a BIOS mod that will get you back at least some of the freedom you should have over your own hardware. Features: WLAN card whitelist removed, any (hardware-wise compatible) card should now work hidden BIOS menus unlocked VBIOS tweaked for more performance and better tuning possibilities Keep in mind that not necessarily all of the BIOS options available with this mod will be fully functional, so use the new available settings with care. If you're unsure about something don't change it and ask here, someone might be able to help. Available for v1.07 / v1.09 / v1.10 and v3.05. v2.04 and v2.07 added (only whitelist removal as for now) If you have a different BIOS (or more specific, a BIOS newer than 3.05) I will need a copy of it in order to make it work for your system. Instructions for flashing the modified BIOS v3.05: You need a USB stick prepared to run DOS, here is a guide you can follow in case you don't know how to do this: Guide by @StamatisX - thanks! >>> Before continuing make sure the AC adapter is connected to your laptop and your battery has at least 20% charge remaining. <<< (0) - NOTE: This step is Only necessary if your system isn't already using BIOS v3.05 Update to the official v3.05 BIOS provided by Lenovo . (1) - Create a backup of your own BIOS (now v3.05) by using Fptw64 tool. Extract the files and run the included .bat file from an admin command prompt. . (2) - Download Lenovo_Y510p-Y410p_[v3.05]_modified.zip and put the files of folder [1] to the root of your prepared USB DOS stick. Let the BiosFixer prepare your BIOS for flashing by drag and dropping your backup file on it. Put the created "v305mod.bin" file to the root of your USB DOS drive as well. . (3) - Now you need to downgrade the firmware back to v2.07 (Y510p-Y410p_v207_[stock].zip) in order to flash the mod. . (4) - Boot from your USB DOS drive, when you see the command prompt type BIOS and hit enter. Wait until the BIOS is flashed (you can safely ignore warnings about non-existing regions). . (5) - Once the BIOS flash completed with no errors, type EC and hit enter. Wait until the EC is flashed. Then reboot. . (6) - Go to the BIOS setup menu, load the default settings, apply and reboot. Done. In case you're using an ultra bay GPU follow the instructions in post #2 and flash the vbios.. NOTE: It's crucial that you flash both, BIOS and EC. Having different EC and BIOS versions can in certain situations lead to issues. IMPORTANT: If you want to go back to stock v3.05 you can do that easily by simply using the official update from Lenovo. That's it, nothing additional required in this case.

Hey Everyone, First off, YOU TAKE FULL RESPONSIBILITY FOR FLASHING THIS! YOU WILL NOT HOLD ME RESPONSIBLE FOR ANY PROBLEMS YOU MAY RUN IN TO BY FLASHING MY MOD! YOU WILL NOT HOLD TECHINFERNO RESPONSIBLE, EITHER! THIS IS YOUR CHOICE! Now on to the good stuff... I've officially cracked it - either by luck or persistence (I'm thinking LUCK, lol) - A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 - FULL CREDIT GOES TO HIM FOR UNLOCKING!) Here is what I've added/updated/modded/changed/etc... ADDED LEGACY SUPPORT FOR THE m18XR2 - You can now run Windows 7 with 900 series nVidia GPU's! Changed the Default GPU from PEG to IGFX - No need to tear down laptop anymore. 8-Beeps are a thing of the PAST! Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132) Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132) Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6) ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated CPU Microcode for other supported CPU's if available! Sorry, I don't remember what version, but if it could be updated, it was!) Updated GOP Driver for Intel Sandy Bridge Updated GOP Driver for Intel Ivy Bridge Updated GOP Policy for the m18xR2 Raidriar added the "Package C-States Lock" to my bios mod - THANK YOU RAIDRIAR! YOU TAKE FULL RESPONSIBILITY FOR FLASHING THIS, AS FLASHING CUSTOM BIOS's HAS SOME RISK!! I AM IN NO WAY RESPONSIBLE FOR ANYTHING THAT HAPPENS TO YOUR PC BY FLASHING THIS MOD!! DOWNLOAD INFO: My BIOS MOD should be available in the download section of TechInferno! They have KINDLY offered to host the file, thankfully! You MUST meet the minimum requirements of T|I in order to download files from their download section! PLEASE NOTE: Do not distribute this file. Please tell others that want the file to download it from TechInferno, as the file is GUARANTEED to be clean if you get it from here. If you download it from anywhere else, there is a chance that the code will be changed, and may BRICK your laptop. Therefore, PLEASE make sure you download from here and ONLY here! I'd like to THANK the following people for testing my bios mods to make sure they are safe for the rest of you: Mr. Fox, Raidriar, Rengsey R.H. Jr! Thanks for testing, I'm grateful! RAIDRIAR, from nbr, needs an EXTRA shoutout for testing. He was UTTERLY amazing! He took risks no sane OR INSANE person would! I owe him for testing this! He deserves a LOT of credit for that! Also, I do have an UPDATE to Intel Management Firmware v8.1.64 (I think), but that is a SEPARATE package. If you are interested, you can do that upgrade, too. HOWEVER, PLEASE NOTE, if you plan on doing update you MUST do BIOS update FIRST - AGAIN, BIOS UPDATE MUST BE DONE FIRST! AFTER bios update is done, then you can do IME update. If you update the IME then BIOS, YOU WILL BRICK YOUR SYSTEM! YOU MUST DO BIOS FIRST, THEN THE Intel ME Update! If you like this mod that I've done, please donate a couple KEGS of beer to me, as I put a TON of work into this. I put more hours into this than I should have... LoL I can also confirm that this has been tested by MANY people. Mr. Fox, Raidriar, and a few others, and they had NO issues. EXCEPT that they were finally able to install Windows 7 while in legacy mode (set from within bios), and the GPU works completely. The only ting I am still working on is the throttling issue on ALL GPU's (Some worse than others). IF you use Mr. Fox's modded drivers, 355.20 I believe, the throttling issue is minimal with the 780m GPUs. Anything above those drivers seems to throttle all GPU's at a more extreme rate. I AM working on this throttling issue, but I am not sure it's fixable. But I will TRY! Again, I hope you ALL like this, and that it helps you out. Lastly, IF you flash my MOD and you decide to purchase another 900 series GPU, please make sure you use woodstackz, as he sells them at the best rates. Please let him know you are purchasing the GPU because of this mod, as it will help me out a little! I hope you like this! Swick Link To Donate: EDIT: I forgot to put fparts.txt in the rar file with all the other files. sorry about that. I'm including it here on this post! SORRY! PS. I AM working on porting ALL these mods to the m17xR4, but dont know if I can get LEGACY SUPPORT ported! I AM TRYING, but if I can't, I'll be able to port EVERYTHING else... File download link:

Hello All, MY Sager NP8651/Clevo P650SE laptop with a Samsung 850 EVO SSD suddenly takes about 3-5 minutes to boot up to the OS whether it's Windows or Linux. I had never flashed a firmware update and on contacting Sager support, who were helpful, provided me with the latest BIOS and EC firmware. I used the MS-DOS and the windows version of the BIOS updater, but it wouldn't update the BIOS. I would get an error. The error log is below: The EC flash worked and it's currently on v1.05. But my BIOS is at v1.03.06RLS11.03 As per the Sager support, the BIOS chip is corrupted and I'll need to ship it to the factory for getting it fixed, which will cost a lot. I tried to flash with the BIOS from the below thread, but it too didn't work. And before anybody asks, I followed the instructions to a T, especially running Meset.exe first and then flashme. Is there a way I can wipe the BIOS clean and flash the latest BIOS? I'm OK with installing a Modded BIOS as well. @Klem - Please don't mind, I'm tagging you for your help as you recently helped someone with another issue but the same laptop model. Regards, Nuttty

Hello! There can someone unlock me Lenovo Yoga 2 bios 113 be for me to be able to access the hidden option Yoga 2 13 bios? I am willing to donate a coffee or two.

This is continuation of this thread (http://forum.techinferno.com/lenovo-ibm/2690-lenovo-y500-unlocked-bios.html) with all the necessary information in the first post in order to make it easier to find all the stuff. Lenovo Y400 / Y500 - 'unlocked' BIOS / wwan-wlan whitelist removal + modified VBIOS for higher overclocking The Lenovo Y500 comes with a pretty locked down BIOS, and in addition to this with a whitelist which prevents the user from getting 3rd-party wwan/wlan cards to work properly. The modified BIOS versions here will take care of this. Keep in mind that not necessarily all options available in the modified bios will work. Some might not do anything at all, others could possibly leave your system in a state which will prevent it from booting. Use care when changing stuff in the modified bios, don't touch things you're not familiar with. Use all the mods and software posted here on your own risk. Read the instructions carefully. NOTE: This will only flash the bios region. It won't reset the nvars set in the bios. *************** ONLY FLASH A MOD OF THE SAME VERSION AS YOUR CURRENT BIOS VERSION!!! If you're on 2.02 or 2.03 you can safely use the 2.04 update, *************** Attached you'll find modified versions of the Y400 / Y500 BIOS v1.03 and v1.05. Removed as they're outdated. Better updated to v2.02. The bios contains your Windows 8 license, therefore you can't just flash any file, else you'll have issue with your Windows activation. Furthermore the serial numbers, service tags etc. are stored there as well. You don't want to loose them. I wrote a little program that will take care of this issue and personalize the modified bios for you, so that you won't end up with an invalid Windows or no service tags. *************** Preparation to get to BIOS v2.02 (coming from any earlier version): Generally it's a good idea to keep the BIOS up to date. We're luck to have an official BIOS update to v2.02 apparently thanks to a leak on the net. (Lenovo is really bad when it comes to providing firmware updates and fixing issues). The leaked version must be genuine, else it wouldn't flash by using the regular method. If you want to update your system to v2.02 then grab the update here, extract it and flash the bios by executing the included InsydeFlash utility. Once the update is completed you can continue with the instructions below to get a modified version on your system. *************** Instructions for flashing a modified version: As a reminder - the modified BIOS needs to be the same version as you have on your system (2.02 to 2.04 is ok). Prepare an USB stick which can boot DOS. If you don't know how to do this, follow this short guide: Download the flash tool, for flashing you'll need the DOS version, but for creating the backup of your current BIOS the Win64 version will do as well, and it is faster. Get the prr tool as well. Grab the modified BIOS you want to flash, it comes as a tool which will patch the bios for you. Make sure you grab the version that corresponds with your BIOS version. Create a backup of your current BIOS using the flash tool you downloaded (first step) by runing the included backup.bat, or by using the Win or Dos version flash tool with this command: If the .bat doesn't work then open an administrator command prompt in your working directory and run the .bat per command line or type the command written above. In case you get an 'error 104' replace the parts file with the one that can be found in the 'error 104 fix' attachment at the end of the post. And if you still have issues after doing all of the steps above then please leave a reply in the thread and describe your problem. Open the downloaded tool and execute it. Drag and drop your BIOS backup file on it, it will create the mod for you. It will look like this: Put the modified BIOS, the prr.exe tool and the fpt.exe (along with the fparts.txt file) on the root of your prepared DOS bootable USB drive, restart your system and boot from that drive. Execute the prr.exe, if you don't get an error message continue by pressing enter. Then flash the bios by using this command (filename.bin obviously needs to be replaced with the name of the file you want to flash). If you can't remember the name of your file, use the command dir to display all the files on your drive. Flash with this: fpt.exe -f filename.bin -bios NOTE: The name of the BIOS file mustn't exceed eight characters (not counting the extension)! That's a DOS limit, so make sure the name of your file isn't too long. Wait until the process is done. After flashing it will verify the data, in case there's something wrong with the flashed data it will tell you. In that case don't reboot, just flash again. *************** Flashing the ultra bay 650m - only for SLI users with BIOS v2.02: The modified BIOS v2.02 also contains a vbios which will allow you to overclock your 650m past the 135MHz limit. As the ultra bay GPU has it's own vbios module you need to flash it separately. You'll need an USB drive which can boot DOS (just as the one you used for flashing the BIOS). *************** It might look a bit complicated at first, but that's the easiest way I could think of. Let me know if anything is unclear. >> Here's the 'buy me a beer' link in case you like this << Use at your own risk, you are responsible for your system and the changes you make on it.

Hey guys, I am Grga and i am new here. I rarely use forums but i am desperate in this case. So, as i have seen many of you have had the issue with obsolete BIOS versions for clevo P7xxZM machines, So i would like to hear your experiences and how you went about it. I have recently bought an ssd Samsung 970 PRO NVMe M.2. From which i would like to boot the windows10. Little did i know that there was no support for that kind of protocol in the BIOS or that there is such thing as UEFI (for which i am still not sure what that is exactly, except some kind of successor of BIOS). So i did a bit of research and updated my Bios and ec to 1.03.15 and 1.03.09 respectively for which i understand is the last available official release. I changed to uefi mode with secure boot disabled etc... in short i did everything that my (limited) knowledge about these things allowed me to do (and the sweat of excitement and fear when i was flashing the bios for the first time in my life). But, alas, it all yielded no success, and now i am lost. I have really no idea what to do, and whom to ask for help except for you guys here. The only thing that i understand worked for some of you is when you mentioned a wizard named @Prema so therefore i will try to do the same....

Hi @Klem, I want to unlock my Dell Latitude 5300 2 in 1 Bios, This is the bios https://www.dell.com/support/home/pl-pl/drivers/driversdetails?driverid=6c7yj&oscode=wt64a&productcode=latitude-13-5300-laptop

PROBLEM: Black screen of death on a Lenovo y580 (or probably most of the ideapad Y series since they all use similar bios software) after changing the setting for which video source gets priority (default is "SG"). SOLUTION: Rather than using the vast array of options that rarely work for anyone like heating up your video card by blocking the fan on a pillow for 20 minutes at a time until it "decides" to start working again - after much research I found the solution for setting the modified slv7 lenovo y580 bios back to its defaults in the event that you inadvertently disable your video. First, press power and immediately hold F2 until your laptop starts beeping, then release. If there is no sound hold it about 45 seconds. Second, press the following button sequence for 100 extra lives: left arrow (1x) down arrow (4x) enter (4x) At that point the system should automatically shut down and restart. If it does not, the settings may not have been changed correctly but go ahead and manually restart to find out. If you come back to a black screen again try the process over until you're certain that the cause is something other than your bios settings. This will save you hours upon hours researching CMOS bypass surgeries, blind usb jump drive bios flash procedures, and all those tedious and time consuming processes. I even started questioning whether my keyboard on my laptop worked at one point it got so screwy. I will add this, if you can use an external monitor and get a signal, do that. Use Fn+F4 to switch to an external signal and that will make your life much easier. Barring that, the above is the easiest solution I was able to track down. Best.. wissper [original issue] This has come up fairly often, and I've read every post I can find trying to fix it but with no positive results so far. I've got a lenovo y580, running a modified svl7 bios. I accidentally changed the video setting that was set to "SG" to some other setting, unsure what. Now I can't get a response from the laptop other than from the power button which simply lights up, but no other indications of life show any more. Early on there was a point at which I pressed some button combo and heard loud beeps, but that has not recurred. I've tried the typical blind default reset method (left, 4x down, 4x enter) which didn't help. I cannot access the computer remotely when it's been powered on which makes me believe that it is not moving past the bios to windows. (no ping response or net view access) I have been unsuccessful in getting an external display to work on the HDMI or VGA ports (though I am going to try VGA again to be sure). Most of the advice I've found says to unplug everything from the system (wifi adapter, HDD, SSD, Optical,etc.), insert a usb stick with various ROM/BIN files conforming to a particular name variant depending on your model, and to hold Fn+B continuously just after inserting power cord w/o battery installed and hit the power button. The 1 time I've tried this, I had copies of the bios w/ extentions .bi .bin .rom .fd with prefixes QIWY3207 or just QIWY3 (which was the suggestion from Andy's phoenix tool that was part of the instructions). If anyone sees a mistake I've made along the way, another method to try, or just knows the key pattern to reset the modified svl7 y580 bios to default I would really appreciate the help. I'm looking forward to buying another laptop about as much as choking down a bag of cement. Thanks! Wissper
