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:
- https://github.com/B83C/huawei_bootloader_unlocker (testing for some hours... nothing yet)
- https://github.com/haexhub/huaweiBootloaderHack
- etc.
Stock images
Huawei seems to have removed any references to these tablets from their websites, but diving into the Spanish Support page or the German Support page, you can still get your hands in the T1-821W's firmware for Spain and the T1-821L's firmware for Germany:
