What is Reddit's opinion of KeeYees SOP8 SOIC8 Test Clip and CH341A USB Programmer Flash for Most of 24 25 Series EEPROM BIOS Chip with PDF Tutorial?

From 3.5 billion Reddit comments

Compiling Coreboot is the “easy” part. This shouldn’t really be a big problem. Follow some of the guides, they’re generally quite similar.

I would strongly recommend buying a ch341a kit (link is just an example) for the flashing part. It’s a lot simpler than using an RPi. Really.

For the T420 you need to disassemble the laptop completely to get to the SPI chip. Follow the hardware maintenance manual and take your time. Keep track of the screws.

Once this is done the first time, you can flash internally later, as long as you leave the flash descriptor unlocked (I think this is default when you compile, if not someone please correct me).

I don't know if this helps at all but - could you check the sticker on the box/on the BIOS chip on your board to verify the BIOS version? 2606 or higher and you're good to go without needing to flash.

Alternatively, if you're feeling adventurous - you could grab yourself one of these and flash the chip:

CH341A Programmer

Since that board doesn't have flashback.

Try resetting the CPU before trying to returning the board to seller.

IF you got a excellent deal maybe it worth buying a USB CH341a programmer w/ SOIC8 Test Clip. Might find a better deal on eBay or Amazon. Below is just so you know what I am referring to.
Better test clip might make the project much easier.

whats the 3.3v mod? The skulls tutorial said that it uses 3.3v but it doesn't generate enough power on its own, but I dont really even know if its the same ch341a programmer that I have. And the other guide I read which had the actual product that I bought (this one) said that I do noed some sort of mod.

You can buy one of theese (https://www.amazon.com/KeeYees-SOIC8-EEPROM-CH341A-Programmer/dp/B07SHSL9X9/ref=mp_s_a_1_3?crid=107XMRYHB00RN&keywords=ch341a+programmer&qid=1651427412&sprefix=Ch34%2Caps%2C330&sr=8-3) and likely recover your bios by flashing it directly.

Regarding your question the 12400f is the better option, it's faster in gaming and still has plenty of multi-threaded performance

Get your self one of these and never haft to worrrie a out singelbioscards die from flash always reflash my favorite tool so easy my dog can flash too

Hi thank you for helping me, hmm I thought CH341 is an EEPROM reader that it is able to at least read and write most EEPROM in the market. Can you explain what do you mean by not talking to each other?

My CH341 reader

Aside from messing with the test points and pogo pins, I believe that some people have had success flashing the memory chip (the SOIC8 IC below the ESP) directly using a programming clip. But that might be a whole other can of worms.

You don't need to mod your Xbox to get the eeprom you could use a eeprom programmer from amazon to extract your eeprom.You could use something like this https://www.amazon.com/KeeYees-SOIC8-EEPROM-CH341A-Programmer/dp/B07SHSL9X9/ref=mp_s_a_1_3?dchild=1&keywords=eeprom+programmer+usb&qid=1596046053&sprefix=eeprom+pro&sr=8-3

You can flash any including an old version. You just need your own programmer like : KeeYees SOP8 SOIC8 Test Clip and... https://www.amazon.com/dp/B07SHSL9X9?ref=ppx_pop_mob_ap_share

the best backup method is to make a 1:1 full dump with a programmer.

I successfully flashed the thunderbolt chip on my T480 a couple weeks ago.

My firmware would not update via software and charging was working only intermittently, issue fixed after the flash. The fix requires another computer.

You want to buy one of these: https://www.amazon.com/KeeYees-SOIC8-EEPROM-CH341A-Programmer/dp/B07SHSL9X9/ref=mp_s_a_1_3?keywords=ch341a+programmer&qid=1660672529&sr=8-3#

These are the instructions I followed:

https://nadim.computer/posts/2018-10-26-thinkpad.html

Make sure to read the manual for the clip to connect it to the chip properly.

When extracting the firmware, you only need tbt.bin, not AssistTBT.bin.

If you have any questions lmk!

Good luck if you try this!

You don't need to solder anything, a ch341a programmer will do the job (this thing: https://www.amazon.com/KeeYees-SOIC8-EEPROM-CH341A-Programmer/dp/B07SHSL9X9/ref=mp_s_a_1_3?crid=RLNIQQNHUZD7&keywords=ch341a+programmer&qid=1656838488&sprefix=Ch3%2Caps%2C172&sr=8-3), you just nerd to physio locate the bios chip on the card.

Would a clip like this be good?

Would a clip like this be good?

Hi, I would like to be able to program this 16 pin chip and was wondering if I can make it work with this SOP8 USB Programmer with this SOP16 Clamp ?

Or do I need need something more advanced like this "High Performance EEPROM Flash BIOS Programmer"

Yes, you'll need to use a physical tool to dump the contents of the BIOS data (CH341A programmer and a SOIC8 test clip).

You can use a paid service to unlock it, sending your locked BIOS dump, and receiving a custom / upgraded unlocked version.

Write the new, modified BIOS data back to the chip using your CH341A + SOIC8 and you're good to go.

Just buy a ch341a programmer ( https://www.amazon.com/KeeYees-SOIC8-EEPROM-CH341A-Programmer/dp/B07SHSL9X9/ref=mp_s_a_1_3?crid=3LSYOBM25X6J9&keywords=ch341a+programmer&qid=1650016087&sprefix=Ch34%2Caps%2C819&sr=8-3).

All you need to do is install the drivers for this thing and the flashing software (i recommend asprogrammer), then you have to physically locate the bios chip on the gpu, attach the alligator clip to it and start the flashing procedure. Very likely it will work and even if it doesn't, it's still dirty cheap (even cheaper on aliexpress if you don't mind to wait a bit more for the delivery)

Here's a guide on how to use it(it uses a different program than asprogrammer but the procedure is the same): https://www.overclock.net/threads/brand-new-method-how-to-unbrick-flash-almost-any-card-amd-or-nvidia.1612108/ https://www.overclock.net/threads/brand-new-method-how-to-unbrick-flash-almost-any-card-amd-or-nvidia.1612108/

Don't know how tech savvy you are but you can easily fix it with one of these https://www.amazon.ca/gp/product/B07SHSL9X9/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&psc=1

You could use a CH341a programmer to flash your modded bios to the bios chip itself. Use at your own risk.

No, like the clip shown in this photo

https://www.amazon.com/KeeYees-SOIC8-EEPROM-CH341A-Programmer/dp/B07SHSL9X9?ref_=d6k_applink_bb_marketplace

It clips from the top onto the chip while it's still in the unit.

You can check warranty status here. https://ggcs.gigabyte.com/Login.aspx?refer=/CheckWarrantyStatus.aspx

If it's not warrantied, you can send it to someone to flash the bios. Or if you feel like doing the research etc., you can buy a tool similar to this one. That's just the first one that turned up on amazon. I'm sure there are better ones out there.

Other than that, sell it on eBay for parts. There are people who buy things like that, reflash the bios, and resell them.

Nothing, black screen with the fan working. But I found this tool, dont know how good it is but it has some good review. https://www.amazon.ca/dp/B07SHSL9X9/ref=cm_sw_r_cp_apa_i_rMxoFb6GPXG71 I will try it out

Here is the link - https://www.techpowerup.com/vgabios/216837/216837

I tried to flash this with nvflash already, but it won't allow it due to a device ID/subsystem ID mismatch. Anyone have a USB eeprom programmer to try? I found a cheap one on amazon (here: https://www.amazon.com/gp/product/B07SHSL9X9/) but not sure if it will work.
