Re: Are T2 bypassable?
It relocks back as soon you reinstall OS?
Do I need anything more than a CH341 programmer for the bypass?Comment

Re: Are T2 bypassable?
As far as I have tested and understood about bypassing T2, it's much much easier, reliable and problem free to just pay 150 USD to checkm8 (they made it possible) for bypassing. In this case, you don't even need to unsolder, program and solder that eeprom.
And you will get a lifetime of bypassing with that.
"Free" T203 method relies heavily on checkm8 database and you might be running into problems with that method.
To bypass, you need another macbook to go into DFU mode and bypass using checkm8.Comment

I’d appreciate some very basic advice on CH341x programmers. I know this topic comes up from time to time, but stuff changes, so I hope a refresh is in order. In particular, I see some unexpected things happening with jumper positions.
[My plan is to learn to read and write 24CO2 EEPROMs via I2C. The first target is the one in my Uni-T clamp meter, but before tackling that I have some brand-new EEPROMs to practice on.]
I have two basic Chinese programmers. One is the blue board with a CH341A and two rows of pin headers. To my untrained eye it looks like all the others.... -
Hello guys ,i have a dell latitude 5590 with f411p bios,this laptop has bios password ,i tried to read the bios(winbond 25q128jv) with ch341 but when goes to verify give error ,it said doesnt match .After this i flashed another bios which is cleaned and then the laptop was dead ,i tried to turn on but only white light in the buton power turned on several times and then no display at all .I had a backup and flashed again the original bios ,but this time the laptop will not turn on at all ,no light nothing,the bios original bios that i flashed was having verify error when i verified with ch341 ,i... -
Hi,
So i've bough a ch341 programmer, and the chip was CH341B . the test clamp was not working( when connecting bios using test clamp, ch341 device was disconnecting) I tried soldering the bios on the provided board, soldering the bios I could read the chip but could not write or erase. ASprogrammer , neo, ch341a programmer... all programmer software was hanging and device was disconnecting after few second of erase/write operating.
So then I have soldered a capacitor(whatever I had..[10v ~470uf ] ) from VCC to GND on my provided pcb where you solder the bios
now all... -

Hi,
Is it impossible to flash Asus TUF B450M-Plus Gaming BIOS(25LB128D) with CH341? I have done it with H270N BIOS.
I used NeoProgrammer and selected 25LQ128C IC since 25LB128D is not in the chiplist.dat. I get no response from IC.
Any expert can help on setting up the import.xml so that I can import 25LB128D into chiplist.dat.
Thanks in advance.
