Hi all; i’m very much a novice in biso programming and even computer components, so sorry if any of my thoughts come of us as obvious or even stupid.
TL:DR I bricked my bios using ru.efi,and am unable to detect it in ch341a (tried multiple softwares and two different ch341as - both using the test clip)
From my understanding my bios chip is a GIGADEVICE: 25B127DSIG with a 3.3v voltage.
I’ve attached two images of my attempted setups: [1] 424470 B1 27 E5 4 F8 F 9781 F309 B592665 A — Postimages - default black ch341a setup; [2] 801 BC3 B1 3142 4380 AC58 B83 A2477 E03 F — Postimages - green ch341a with a 1.8v adapter.
In both attempts i attached the ch341a with the test clip, with the red wire corresponding to the circled leg on the chip. I’m not sure as to whether the razer chip is SIP, and can threreby be programmed without soldering, but from what i’ve read people have programmed it directly through the test clip.
I’m not sure what else i can do to force the ch341a to detect my chip, and i feel as if running out of time given my main pc is now totally inoperable.
I’ve tried multiple programmers - asprogrammer, neoprogrammer, che341a programmer - and have all drivers installed on the pc being used to flash. I’ve also been able to connect the actual ch341a, but the chip still remains undetected, or, in some cases, the ch341a disconnects depending on the test clips placement.
Please, any help would be greatly appreciated

Some boards require power standby, cmos battery on/off but since its a 3.3v IC… i wouldn’t risk it, supplying more power.
This happens when theres a tie to the PCH and SPI/EC IC bios on the motherboard/circuit design.
If the clip has a grip connection to the IC (not easy for newcomers) and still no detection with all those flash apps… desoldering may be the last resource.

Thats all, nothing more to add from me and good luck.
Hi all.
Without wasting time, im looking to see whether anyone here with experience modding razer laptops (specifically with the ch341a), can answer a few questions regarding the process. My specific model is the razer blade 15 base, 2020
-
Can the bios chip be programmed directly using the test clip, or does it have to be soldered onto the board?
-
Does programming require the cmos chip to be deactivated or activated?
-
Does programming require external power?
Would really appreciate any answers as it’d help me tremendously
So you didn’t waste your time reading the guides/threads shared in your previous post…
If you did you’ve had learned that its difficult to apply a general rule for flashing… can you imagine an answer to every kind of model/brand of hardware in the current/past market?
1 Most desktop motherboard can, laptop also but has a shorter margin…
2 CMOS battery? General rule, battery OFF.
3 General rule, NO.
I looked through the threads you posted and they were all too general to solve my problem. Why im asking specifically for razer experience, since im assuming my problem is specific to razer’s configuration.
If anyone reading this has experience: does the ch341a give off enough power to program the razer’s chip directly? From my experience the ch341a’s red light dims or even disconnects whenever its connected, so im assuming its a power issue, even though ive read threads and posts of people programming my model directly
