Lenovo IdeaPad 3 15ADA05

[stjopa]

Hello! I would like to ask for help because I am completely stuck with this machine. The battery on the machine ran out during the update and since then only the power button LED has been blinking. I have tried several BIOSes from the site. With the factory e8cn36ww.bin, the Lenovo logo came up once, but never again. I would like help in creating a clean BIOS. I have attached the original BIOS dump. Thank you for your help!
Machine type: Lenovo Ideapad 3 15ADA05 (81W1)
Serial number: PF29E61X

RiderXO Yesterday when I flashed my Lenovo Flex 5 14ACL05 with a Winbond W74M12JW bios chip with a EZP2019 I had to do the following:
- use a 1.8 V adapter
- manually choose the most identical chip id as the EZP2019 wrongfully detected the bios chip as 93_EEPROM, ATMEL, AT93C46@16.
I went with SPI_FLASH, Winbond, W25Q128JV, (1.8v)
- double verification of reading bios with 3 Mhz setting as higher fx 12 Mhz did not produce the same data each time.
- Erase bios before writing then verifying bios data (Lesson Identified: if you only write - verify it's gonna produce an error).

ie. did you erase before writing ?

Yes i did erase the chip every time. EZ detects mine as W25Q64FW(1.8V). by default. And yes, i am using an adapter for 1.8v. If i search in EZ programmer database there is no 25Q64JWSIQ

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Hmm, yeah i am using the clip. Would a normal heat gun work?

Here is a photo of my chip:

Weird, i tried a second time, with the same file and now i got error at address 4ABh

I tried flashing the one from post 207 you added there, the name is the same as on the lenovo site : e8cn41ww so i think the bios is ok, but i still got a flash check error at address: 2001Fh. I think the chip has something, because before i flashed in windows the wrong bios, i had issues with the laptop. It wasn't shutting down completely, always had to press and hold power button, then when i started it, it would stay black screen for at least 3-4 minutes tgen it would open the windows logon, or in some cases it just spined the fans like crazy without any image displayed. It did so even on a fresh new win11 . That is why i tried to update the bios in the first place. If i buy a new chip, i suppose i must flash it with the programmer right? If yes, is the same procedure? Or the lenovo official bios needs some modifications to be able to flash it on a brand new bios chip? I think i saw some winbond chips like mine on aliexpress. Or could you recommend me a shop here in Romania? Multumesc peste.

I have a Lenovo Idea Pad 3 15ADA05 with SN PF25MJ4G. The bios chipset is Winbond 25Q64JWSIQ. The laptop is briked due to wrong bios flash. I got myself an EZ2019+ programmer but the bios.cap is biiger then the chip (8mb), I tried flashing
NM-C821 DUMP.rar _posted on the first page) but i get flash check error address 0H and the laptop is still bricked (black screen). The programmer detects my chip as W25Q64FW(1.8V). If i search in the EZP2019+ app after 25Q64JWSIQ it founds 0 results. Anyway, is recoverable my laptop? Or should i burry it?

try post #206..

choose the chip manually...if you don't have it in the database, choose an equivalent one..

Yes and upload your dump

Hey guys, how are you?

I have this IDEAPAD 3 14ADA05 (serial PF2AE2SS) thats seems to have a faulty onboard ram... Is this the place to ask for a modded BIOS with onboard disabled?

Thanks so much!

I am infinitely grateful to you. I am very intrigued to know how they modify it to make it work. Is there a way you can explain it without bothering me too much? With how much you helped me, I don't want to bother you.

Hello everyone, I would really appreciate your help.

I updated the BIOS using Lenovo software and the screen went black.

I don't know how to modify the bin file that I found here, I'm leaving you the backup and the bin that I found in the forum, if you could help me pass the modified one with the DMI of my laptop.

Serial number ?
