RE: [REQUEST] FiX and MODDED BIOS for PH315-52-78VL

Hi i recently bricked my ph315-52-78VL bios. I updated windows 10 and just nonchalantly ticked the optional update for my bios… computer restarted and fans ran on high for 30 minutes. Bricked bios I have the chip attached to a Ch341a programmer after doing the battery power reset to no avail. I am in need of a working bios file to program the chip. Also it has always bugged me not being able to change ram voltages and timings is there a way to unlock the bios and hit two birds with one stone? Thank you in advance! ( @Sweet_Kitten is it fine to post here?)

Sorry for posting on that other thread im used to being on a pc its a little weird posting to forums on a phone :sweat_smile:

First, we will try to fix your bios. You say you have CH341A, upload chip data so I can download it.

The forum is not letting me send a link and the file is 16MB too large to attach

Hi, @SaltySnakeFarm
Need to restore your bios only…otherwise you may lose your motherboard

@SaltySnakeFarm , now, write this bios backup file to your chip. Report results.

@SaltySnakeFarm first use the serial number of your laptop, find the update of your bios on the Acer website and post

Programming memory(verifying)…
Verification error on address: 00000000
Execution time: 0:00:00
keep getting this error on writing

Sometimes programmer cannot write properly if the chip is still soldered to the motherboard. How does the chip attached to your programmer?

I have desoldered it. I really dont like to use the clips and have it in a sop8 socket directly attached to the ch341a.

https://drive.google.com/file/d/1mdB_owO…iew?usp=sharing Here is the updated bios File from acer

I am using AsProgrammer version 1.405 on windows 10 if that could be causing issues? Maybe a driver problem?

Hm. It becomes more complicated. I just took the BIOS dump from the working device, replaced the identification data in it with yours, and gave it. Maybe @Pythonic wants to prove himself?

Well If all else fails I can order a new Bios chip… or send it to acer and have them replace the whole motherboard for 600 US

I have successfully wrote the bios using a different ch341a programmer software but I will not know the results until probably monday now due to working all weekend. Cheers for all the hard work you guys put in and I will most definitely be donating to keep this site alive!

@SaltySnakeFarm
Yes there are two sw actually working well on win 10 AS programmer v.1.41 and i found with an smart user the MiniProgrammer (may be a clone of ASP), then
Colibrì … , if you need them , i can upload for you !
Regards

P.S. I think you can trust Sweet Kitten , he is the best bios modder here …

Its always good to have a little friendly competition now and again but as long as the firmware works for my chip its all good. I was tempted to boot up linux because windows is well windows. I would happily accept the links to the software and use the one that works the best. Windows is always finicky at the best of times.

Thanks to pythonic I got the system to boot with the updated firmware and a successful flash. Thank you @Sweet_Kitten for the initial support. It is really a chore pulling everything apart from the laptop to get to the bios chip so I may just leave it as is. :sweat_smile:
