0000 Posted February 15, 2015 Share Posted February 15, 2015 Hy,my EC flash on an Clevo W350/W355 (Schenker XMG A504) went wrong. Screen stays black but USB access indicator and Laptop LED are working. the fan speeds up when i keep holding fn+b, which tells me that the keyboard is still working despite the failed ec flash.Any hints on how to get this working again?I´ve found the perma recovery guide for failed bios flashes, is there an equivalent for ec?Thanks in advance.cheers!

Guest Posted February 15, 2015 Share Posted February 15, 2015 The EC isn't bricked if the system still charges, FANs work, keyboard functions etc. A system with bricked EC would do anything.Do a CMOS reset... Quote Link to comment Share on other sites More sharing options...
0000 Posted February 15, 2015 Author Share Posted February 15, 2015 Ok, i will try that first.Is there anything else i could try when this is not working? An emergency recovery for the ec like for the bios?thanks! Quote Link to comment Share on other sites More sharing options...
Guest Posted February 15, 2015 Share Posted February 15, 2015 There is no internal EC recovery. Quote Link to comment Share on other sites More sharing options...
0000 Posted February 15, 2015 Author Share Posted February 15, 2015 Bad news, thanks anyways!The USB access indicator at the flash drive is on, and no matter what key i hit all LEDs on the laptop start flashing. Screen stays black.So CMOS reset apparently did not work. Most probably need to send it in. Should i rather send it to XMG/Schenker or the german Clevo Service partner?

Guest Posted February 16, 2015 Share Posted February 16, 2015 Are you sure you flashed the EC and not the BIOS? No BIOS flash involved at all? OR maybe you flashed an EC for another system?Try this file for FN+B: https://mega.co.nz/#!7FkhERrY!_6oYJhhhk7UAqiIHzh5VRjMF0pvSdUt8NVBhZBUUSdcIf it is indeed the EC, then you will need a new motherboard as no re-seller will be able to reprogram the firmware hosted directly in the 133PIN ITE controller as its documentation and required programmer software is still classified.

0000 Posted February 16, 2015 Author Share Posted February 16, 2015 Sounds bad...Is there a difference if I flashed an ec file for a different system to a failed ec flash?Could the wrong ec file be recovered? Thanks again Quote Link to comment Share on other sites More sharing options...
Guest Posted February 16, 2015 Share Posted February 16, 2015 If you have a wrong EC then you need to try recovery by using the matching wrong BIOS. Quote Link to comment Share on other sites More sharing options...
0000 Posted February 16, 2015 Author Share Posted February 16, 2015 Might have flashed the ec for the P504, Clevo P157SM-A.EC_1.03.08Any chance this would work with the right bios? Quote Link to comment Share on other sites More sharing options...
Guest Posted February 16, 2015 Share Posted February 16, 2015 When we use FN+B the BIOS on the USB is booted from instead the one on the system, so yeah, there is a small chance that it'll at least boot to flash the correct ones.I'll prepare a file for you later...

Guest Posted February 16, 2015 Share Posted February 16, 2015 Try to use this file for FN+B: https://mega.co.nz/#!qF8FlTKJ!lIidophm0-UTrHljNRIzPtJ54391Hr-DSgh3FPs9lU0Also keep the W350SS stock files on another USB stick to return to stock (if you get it booted):http://forum.techinferno.com/clevo/3119-%5Bbios-vbios-mods%5D-prema-mod-stock.html#post54054 Quote Link to comment Share on other sites More sharing options...

0000 Posted February 16, 2015 Author Share Posted February 16, 2015 Hy, tried your file. The A504/W355SS is not booting with the P504/P150SM bios. Screen stays black, fan starts when pressing any key. I tried the method on my P303/W230ST which is working fine and booting into recovery. Seems like i need to send it in. Cheers!
