Acer Aspire v3-112p-P5B3 unlock/SLIC BIOS

[jozsi76]

Hello,

I want to make a slic 2.1 mod on this netbook: Acer Aspire v3-112p-P5B3 (ZHK)
This model similary to ES1-111M but this one with touch screen.

The original BIOS: http://global-download.acer.com/GDFiles/...13_A_A.zip
The BIOS .exe after extracted, contain no BIOS file. The BIOS file "isflash.bin" is maybe encoded in another files, but you can get the bios file with a little trick.
I run the extracted .exe package under Linux/Wine. After the error message i found the opened isflash.bin under Temp folder ;-)

After decapsulate the bios (BDMaster GUIDE Extract Encapsulated Bios), i was able to load the SLIC2.1 module with Andy's Phoenixtool2.66. After reread is the SLIC-mod seems to be correct.
But the bios eeprom seems to be locked :-(
InsydeFlash.exe let me only flash an original bios. if i change only 1 bit with hexedit, the flash failed.

this thread seems be similary: https://www.bios-mods.com/forum/Thread-R...ht=es1-111

the result.rar created with "BACKUP_Tools14a": http://rghost.net/85PjlMDdP
after sleep awakened: http://rghost.net/8lRvr8dTw
Is there maybe any chance with FPT tool or trough sleep bug?

the bios file out of the .exe: http://rghost.net/8xM4WpNtl
my encapsulated bios: http://rghost.net/7xLHvLWqt
The tool "FPT Tool 1.1.1145" retrives that: http://rghost.net/6rl24KqsC

perl uefidump.pl wrote this:
"Use of uninitialized value in numeric lt (<) at uefidump.pl line 245.
Can't use an undefined value as an ARRAY reference at uefidump.pl line 69."

With "Universal IFR Extractor.exe" i got the IFR.txt: FE3542FE-C1D3-4EF8-657C-8048606FF670_737 IFR.txt: http://rghost.net/8nDs5xtHH

What do you think, is it a chance with the FalseClock Methode? If yes, can everybody help me what a VAR i should set from this IFR file to unlock the flash process? Or even is it possible to unlock the eprom?
Is there any option without the SPI programmer?

Next problem: FalseClock's EFI stick won't work.

3. Take USB stick and format to FAT32
4. Create directory structure EFI\Boot
5. Download BOOTX64.EFI
6. Put downloaded file to Boot directory.
7. Restart and enter BIOS setup.
8. Make sure you have following values:
Legacy Support: Disable
Secure Boot: Disable
9. Reboot and press F9 to boot from USB stick

but after it i have only a black screen

Is there somewhere to download a newer bootx64.efi file?
Any suggestion how I can try to boot in EFI and take a "setup_var" commands?
