FOSS bootloader


Contributors

  • Roboe: collecting scarce available information and sources before trying to port pmOS. Currently brute-forcing the bootloader unlock.

Users owning this device

  • Roboe (Notes: (second hand) T1-821W; running stock Android until I manage to unlock its bootloader)


Models

There seems to be three different models: one wifi-only with 1 GB of RAM, and two others with a LTE modem and 1 GB/2 GB of RAM.

Model LTE modem RAM
T1-821W No 1 GB
T1-821L Yes 1 GB
T1-823L Yes 2 GB

Anyway, I (Roboe) have the wifi-only model and its stock Android's ro.product.device is hwt1821l and its ro.product.name is t1_8p0lte.

How to enter flash mode

Using ADB from stock Android:

  • Recovery: adb reboot recovery
  • Fastboot: adb reboot bootloader

With hardware buttons:

  • Recovery: Power on the device with both Power and Volume Up buttons.
  • Fastboot: Unknown.

Unlock bootloader

Unfortunately, official unlock method was shut down by Huawei on May 24th, 2018.[1][2]

Fortunately, the open source community is awesome and there are a number of brute-force alternatives:

Stock images

Huawei seems to have removed any references to these tablets from their websites, but searching in the Spanish Support page you can still get your hands in the T1-821W's firmware for Spain:

This contains a PDF file with instructions (in English) to sideload the update from the SD card using the stock recovery, and the UPDATE.APP file containing the actual OS. There's a number of projects to extract flashable images from UPDATE.APP:
