Flashing HP Elitebook x360 1030 g2 with EZP2023+

[Souricier]

How to be sure it is dead ? CH341 does not see it but EZP2023+ sees it but wrongly...
If I buy a new one, what bin will I flash on it, I don't have backup ?
On the official HP site, the BIOS bin corresponding to my SN is only 9Mo instead of the 16Mo of the chip ... what does it mean ?

If the EZP can see it the CH341A should do.There is a voltage mod that you can do to the ch341a black edition ,if you have a soldering iron and a piece of wire. I`d suggest resoldering all of the pins on it as well.I`ve had 2 CH341A`s arrive DOA ,resoldering the pins fixed them.

If you have a black PCB, it is very likely that it needs to be modified for 3V operation instead of 5V. Failing to do so could damage the ROM IC.
Watch the instructions there:

The bin at HP is only a bios update,not the full bios image. Keep trying to make the backups.

I am sorry but I am not able to do the soldering you describle roughly. I don't uderstand why CH341A would be better than EZP or XGPRO, XGECU.
I am beginning to admit that my laptop is now dead. Do you have another hopeful idea ?

[SMDFlea]

The CH341A is better than the EZP. If you can afford a better programmer the XGECU T48 is a good choice.

[Souricier]

Why should I modify the voltage of the CH341A, my chip is a 3,3v and should support natively the CH341A isn't it ?

[SMDFlea]

The videos explain why, it has 5V on the data lines, it is a design fault.

[Souricier]

Well, I tried again on EZP and it read the chip but says it is empty.
If it's really the case, what can I do ?

[Souricier]

By the way, I tried again with CH341A and As Programer and this time it was able to read it but everything's blank...
What can be tested ? Could you provide me a bin compliant with the caracteristics of my laptop ?

Thank you very much for your help, I did not answered as I was a little bit desesperated by my readers not functionning...
I have just ordered new chips to write your bin on.
I will inform you when it's done.

[Souricier]

I have finally bought new chips.
But when I write the BIOS file on both chip (original one or new one), it says nothing particular but when I run verify process :


And when I try to read again the chip, it says it's empty !!

[Souricier]

I have finaly bought a T48 programmer and I succeeded in flashing my chip.
I put it back on the motherboard but now the laptop is not starting and the power is blinking orange/white with key with a lock on the keyboard blinking white also.
I have removed battery but same error.
Do you have any clue ?
