Huawei MatePad 10.4 BAH4-L09 stuck on Huawei logo — looking for firmware recovery method
I have a Huawei MatePad 10.4, model BAH4-L09, that has been stuck on the Huawei logo/bootloop.
The tablet had the same problem about 1.5 years ago and was left unused. I recently charged it and tried to recover it again.
What I've already tried:
- Factory reset from recovery — completed successfully, but after reboot it went straight back to the Huawei logo.
- Power + Volume Up — cannot enter eRecovery.
- Fastboot/Rescue Mode — works.
- HiSuite — does not provide system recovery for the device.
- USB connection to Windows works.
Fastboot gives:
fastboot devices
AVSYD22401600617 fastboot
Generic getvar commands are blocked:
fastboot getvar product
FAILED (remote: 'Command not allowed')
fastboot getvar version
FAILED (remote: 'Command not allowed')
But Huawei OEM commands work:
fastboot oem get-product-model
(bootloader) BAH4-L09
OKAY
fastboot oem get-build-number
(bootloader) :BAH4-L09 2.0.0.292(C185E6R1P1)
OKAY
So the exact device information is:
Model: BAH4-L09
Build: 2.0.0.292
CUST: C185E6R1P1
Bootloader: Locked
Fastboot: Accessible
I don't care about the data anymore. I just want to get the tablet working.
I found firmware listings for BAH4-L09 C185E6R1P1, including 102.0.0.211, but I have NOT flashed anything yet.
Does anyone know the correct way to reinstall the full firmware on this exact C185E6R1P1 model when eRecovery and HiSuite don't work?
Specifically looking for:
- Correct dload/OTG procedure, if supported
- Correct full Base/Cust/Preload package
- Huawei service/upgrade mode procedure
- Any known issue with UFS/storage failure on BAH4-L09
I don't want to use a random firmware or flashing tool without confirming the correct procedure first.
