I have the original BIOS backup.
if anyone can help me
thank you
Hello,
I'm not sure that I completely understood your situation, nevertheless, if your BIOS chip is in working condition, you can try once more to use the following procedure:
1. Do a bootblock recovery to flash the proper rom.
2. If you have access to another machine, format a USB stick to FAT32.
3. Run AW15A05.EXE /writehdrfile. (Or whatever version you used BEFORE you bricked, as usually the bootblock isn't updated, but with some BIOS updates, it can be, so your more safe to use the same version you had on the machine BEFORE it bricked from improper flash.)
4. Now take this HDR file and rename it to AAP10.hdr. Put it on the root of the USB.
5. Now make a copy of this file and rename it AMIBOOT.ROM (all caps) so now there's 2 files on the USB key, AMIBOOT.ROM and AAP10.hdr. (Unconfirmed if uses old AMIBOOT.ROM or the new filename I found.. New aptio platform we haven't really played with yet, so lets use both..)
6. Now here's the fun part, you need the technical guide from
dell and disconnect your MAIN battery, not the CMOS battery.. And unplug the PSU..
7. Now, insert your USB stick, hold down END key, plug PSU back in with battery removed.
8. It should turn on and after 5-10 mins, you should see USB activity.. Wait the FULL 10 mins. (Or until it shuts off on its own). Some have reported it took 2 mins when we were testing.
9. After this, try to shut it down using POWER if it didn't on its own, but it should. Then turn it back on.. You should be back on your system.
You don't need to flash again after, as this recovery will flash the complete ROM.. And don't' forget to reconnect your battery..
However, this time add in your usb the .sys file generated when you execute the command "writetohdr" in the command prompt. Moreover, put the executable e.g. AW15A05.exe in the usb as well, and copy this file (AW15A05.exe) and rename it to BOOT_IMG.rcv.
To summarize in your usb you should have:
1. AAP10.hdr
2. AMIBOOT.ROM
3. xxxx.sys (I don't remember the name of the output file)
4. The executable e.g AW15A10.exe
5. BOOT_IMG.rcv
And then plug the usb, press the end key and plug the psu cable (as you did before). I tried this and it worked. Let me know.
Cheers
