What's is your problem?
You need one empty usb stick and copy unlocked BIOS file from: https://1drv.ms/f/s!Aitxvg2kqC-ijzsLVLANUQkbUyEo

The file from your ClowdDrive is not a legit rar.... or any known archive, which could be handled by uniextract.....
Maybe something went wrong?

No problem with RAR. Just test archive all OK.
Please update your Winrar.

Was a problem during download Undecided
Now I can open the file without any problems. Will try to flash as soon as possible.
Any good way to thank you? (Maybe the way explained in redme?)

OK, I also tried with different approaches: no success.
The problem is probably, that we cannot enter the BIOS-Recovery, or BIOS-Recovery does not recognize the ROM you supplied.
I tried a stick with original filename, then renamed it to BIOS.fd, then tried two other sticks.... Without any success.
Any other suggestions?

The filename for BIOS-recovery should be "FRKY.fd" (without the "108" that's currently also in the filename of the ModBIOS).

still did not work....
I use 16 GB USB 2.0 Sandisk stick, FAT32, with FRKY.fd on it and nothing else.

1. I disassamble my laptop to disconnect the battery
2. Pull AC out of laptop
3. FN+ESC
4. Plug in AC
5. Power Button
6. Laptop checks the stick (LED blinks)
7. Few seconds after I can see the Acer logo and "No bootable device found" message

Few months ago I've seen that there is some kind of "sleep-modus" bug, that can be used to access the bios and flash it.... with some tool....
I also tried to use the Insyde flasher, but that says that the version is the same.....

Ok, then the recovery probably checks the signature of the BIOS.
To be absolutely sure, please try the recovery process again with the original BIOS: https://drive.google.com/open?id=0B4NHIB...VU3eURQZzg

If that works, we'll need to try another method.
The sleep-bug has no use for you as it needs a suitable flasher (which is only available for Intel and AMI systems afaik).
The Insyde flasher is not usable for this as the BIOS will check the signature of the file anyway (even if you bypass the checks of the flasher).

In that case, something like this might still work (needs to be adapted): http://www.geektech.co.nz/how-to-unlock-...enovo-y700

The according setting in your BIOS:
0x1C40B Setting: SVM support, Variable: 0xEE {05 91 54 02 55 02 54 00 34 12 EE 00 00 10 00 01 00}
0x1C41C Option: Disabled, Value: 0x0 (default) {09 07 27 00 10 00 00}
0x1C423 Option: Enabled, Value: 0x1 {09 07 28 00 00 00 01}
0x1C42A End of Options {29 02}

To try this method, you will first need to request the utility used in the guide from the author (as written at the end of the guide).
When you have that, please dump the variables as written in the article and send the file to me.
I'll make the necessary changes and send it back to you so you can continue with the rest of the guide.
