Bios recovery on Aspire V5-552G, need help

Jegi

Hello.

I tried to update the bios on my Aspire V5-552G using the latest version from acer support website. It went wrong..

After running the exe, my computer instantly rebooted without giving me the option to install the bios update, im pretty sure it auto installed. And after reboot it starts to black screen with fans running.

I have researched how to recover bios using the Fn+esc combo having unpacked the files from the .exe on a usb stick, but i cant get it to work!

I was unsure about what key combo to use for recovery mode, so i tried booting up holding the fn+esc keys, and it worked, once. Since i didnt have a usb stick in it, it booted to a blue error notice stating it was missing flashable file. 

All good so far i thought and went on to prepare the usb stick, formating it (i have tried fat and fat32), unpacking the zip file with the executable to my hdd, and then unpacking the .exe using 7zip, and putting the files on my formatted usb stick.

Now comes the problem. I cannot get the recovery mode to work again. If i follow instructions to install the usb stick, hold fn+esc keys and press power, the screen is black and nothing happens except fans starting.

And i cannot get the blue error notice to re-appere by doing it without usb stick installed, only black screen.

I think the recovery mode activates though.
If i start the computer normaly, there is a blue led shining constantly, but with the fn+esc combo that led is blinking instead. However i cannot get any response from the flash utility.

Please help me!

1) convert the pendrive to mbr and format it to fat32 in cmd as administrator with the following commands: diskpart, list disk, sel disk x (x is the pendrive number), clean, convert mbr, create partition primary, format fs = fat32 quick, assign and active!

2) Put windows to display hidden files!

3) Go to C: \ Users \ your username \ AppData \ Local \ Temp and delete all files! Can delete without problems!

4) Download the bios 2.07 or 2.05 file on the acer website and run on another computer! A message will appear in error and do not give ok yet!

5) In the temp folder, a .tmp folder will be created! Click on it and you will see a file zribiosR.fd! Copy these files to the desktop!


6) Rename the file zribiosR.fd and rename it to ZRI.FD and copy only this file to the pendrive!

7) Unplug the notebook from the electrical power and plug the pendrive into the notebook!

8) Press the fn + esc keys, turn on the notebook power and press the power button! Just release the fn + esc keys when you hear the cooler spin hard!

9) The flash drive will flash and the process will take three to five minutes!
