FPT Operation Passed

Unpack .rar file and look result3.png and read info.txt !!!
So You have to use FPT 9.5.14.1724 and Svl7 Prr.exe tool to bypass Error 28 !!!

http://rghost.net/59280210

I uploaded here Original FPT 9.5.14.1724 folder so use It to copy all files from modified folder to USB Root place and then add too the bios.bin (Bios Mod) file and try again !
Disable SecureBoot Set Legacy Bios USB into Bios, Boot from USB and then run Flash.bat !!!
Let me know
Regards


P.S. I don't know what You are doing, but Results file say It have to work !

Yes my friend,
You need a SPI PGM look here :

Hopefully not hi-jacking this thread. I'm looking to flash this BIOS once my SPI PGM tools arrive.
Does this eliminate any whitelist as well open the advanced tab or just give access to various configs?

Also if someone would be kind enough to re up the modded bios?
Once I've got everything up and running I'll be sure to donate to ya BDMaster

Yes It is NWL + ADV , but We have to get FULL_DUMP file from your Eeprom :

GD25Q64    ID:0xC84017    Size: 8192KB (65536Kb)

So when You will get SPIPGM You have to read Eeprom and upload this file for me !

That's great news, just to run through:
so I'll perform the EEPROM dump by identifying the GDS25Q64 by its marking.
Connecting with the CHA341A (I'll be using clips - my decent soldering iron isn't with me)
Dumping it to a second machine using the software provided with the CH341A
You'll kindly modify it
I flash the new file using the software I received with the CHA341A

I'll be doing this around the 15th Dec (those test clips take a while!)

There's an updated BIOS available now, any reason not to flash that and use it for this process other than the old 'ain't broke don't fix'?

Also PM Sent to you BDMaster

I repled in PM !

WOO Finally got my Z50-70 Flashed to no whitelist and advanced options!!

So many thanks to BDMaster for this! All working perfectly at long last.

I can't say I can help mod the bios or the flash but if anyone needs any pointers locating the chip itself to flash or anything let me know!

For anyone interested I can provide a picture of the chip location. It's a little further away from the CPU and a lot closer to the Wi-Fi card than expected.

Also don't make the same mistake as I did with the CHA341a software. Follow the guide https://www.bios-mods.com/forum/Thread-R...?pid=74575

Particularly using the auto button rather than "write" or "program".
