I think I bricked the phone!
Backups files I already have
A-WRP is correctly installed and I made a full nandroid backup.
B-I have a full partitions backups made with Partitions Backup and Restore App (Root access required). I backup all the partitions, all of them in raw mode. All the files are *.img ready to flash with fastboot.
C-I have a full B132 ALE-L21 stock ROM that was working perfectly before.
1-adb is not recognizing the device
2-fastboot is not recognizing the device
3-I cannot enter TWRP
4-Huawei EMUI 3 buttons (volume up + volume down + on/off button) function doesn't start neither (I'm trying to force the update to B132 ROM)
5-The phone enters directly to Rescue Mode and says:
error! Func NO : 8 (hifi image) Error NO : 1 (Security verify faild!)
So the phone is still working and I got this RESCUE MODE screen but I can't do anything when this screen is displayed.
Any idea? What can I try?
Please, I really need your help, anything you can imagine to try please, let me know!!!
Thanks in advance!!!
Finally I was able to enter in FASTBOOT & RESCUE MODE following this procedure:
1-Turn off the phone
2-Connect USB cable to computer but NOT to the phone
3-Press the volume down button and hold It
4-Connect the USB cable to the phone
5-Ready, the phone will turn on automatically in this mode (DO NOT press the power button)
So, now I have fastboot but I CANNOT flash the f.....ing HIFI partition
-fastboot flash hifi hifi.img --> command not allowed
-fastboot flash radio hifi.img --> command not allowed
-fastboot flashing unlock --> command not allowed
-I tried to enter recovery mode. I have TWRP installed, I can also flash It again with fastboot, everything good but can't access It after that!!!!
-ADB is not working
-I flash a B052 ROM, then put B132 Update.app file in SD Card root\dload and try to force update by pressing volume up + volume down + power, nothing
-I flash the B132 ROM again , then put B170 Update.zip file in SD Card root\dload and try to force update by pressing volume up + volume down + power, nothing
-I try fastboot update update.zip but It says no android-info.txt nor android-product.txt
-I try to create a flashable .zip file for fastboot but It requires .sig files for the boot, recovery and system partitions
-HiSuite open ups automatically on the computer but can't connect to phone, the phone is not recognize by HiSuite but in windows says Marshall London Bootloader Interface. I can change that to Huwaei HDB Interface, Android ADB Interface, etc. etc. in device manager. A couple of times in the phone screen refreshes saying "Rescue mode enter.." but no way, HiSuite can't connect.
I tried lastest HiSuite version v220.127.116.11 and v18.104.22.168, nothing.
So, I have fastboot, what else can I do? Can somebody help me build a .zip file flashable with fastboot?
Is there any other fastboot or tool (I tried mfastboot too) that may allow me to flash HIFI partition?
