RAZER BLADE advanced 2022 rtx 3080 no post/display rz09-0409cec3

Hi guys, i just got a brand new razer blade 15 rz09-0409cec3 that turns on keyboard light, fans but no display at all. I managed to get bios bin file from razer but im not sure if this chip is THE bios chip. It is a Gigadevice 25q64cig (Uee704 Aj2103) or something like that. I believe that is the bios chip, I uploaded photos from all of them in case i am wrong. https://drive.google.com/drive/folde...9M?usp=sharing If its ok i will remove it, read it with ch341A , backup and share bios file here so you can check what is wrong. I will try to flahs bios bin file from razer too. Will upload all together once im sure its the correct one. Wich program do you recommend to read it ?
Thank u a lot!

i think it is 1,8V ic. check by datasheet if u need adapter

Hey - I’m trying to figure out the same thing. Which chip is it for the 16mb bios file?

The only ic I haven't been able to dump is the Winbond W25R256JVEQ so I guess that must be it? It's almost flush with the motherboard though and is impossible to get clips on.

If that is the bios chip - any tips on how to read/ write without desoldering?

Dunno what's the question here. The datasheet of the Chips will give the answers. Top marking of the flash in question is W25R256JVEQ, so 256 / 8 = 32MB. It is WSON package so you have to put wires, or even better, to solder it on a suitable programming board.

Thanks @sephir0th - Still new to hardware. Was looking for someone more experienced to make sure I’m on the right track. No real question I guess. Appreciate ya

The best solution is to carefully remove the flash chip, solder it onto a small smd to dip bridge board. Then perform your reflashing.

Do you have a flash programmer? Which one?

Be careful to confirm the peak VCC pin voltage of your tool and the target flash device before proceeding. Else you can kill the flash memory device.

Ps: where in Ontario?

Thanks mon2.

I’m in Toronto. I have an EZP2019+ that works at 3.3V, and a not volt modded ch341a. All good with pin alignment and stuff; being extra careful to not fry anything. Think I’ll be fine as long as I can find a tech somewhere willing to help with the soldering (open to suggestions if you know of anyone)

Recommend to phone around your area to ask about low level board repair techs - most likely cell phone repair techs.

If you are near Mississauga - contact via PM -> @mferna14.
