Probably you can flash this.
Okay, here it is. The reason you have no keyboard or rotation or the other little things that don't work is you didn't flash the whole package. The stock rom comes in multiple parts. There is a hardware .zip that has hardware and localization files in an update.app that is a lot smaller than the main update.app. The testkeys have nothing to do with it not working it is just that it gets flashed by itself by so many people that it is believed to be at fault. I believe the full file set is available with reference and link in this thread. If not I have the three part OTA from Huawei archived somewhere, I just seen it in the last day or so. I didn't realize I still had it, and yes it is from huawei servers when they still updated this tablet.The tablet had been converted from JPN version. When I originally got it, it had c100 firmware
The problem is, file downloads for firmware are difficult to get. I did find EMUI 5 which is needed before going to Lineage however it didn't rotate, no default keyboard and it is the test keys.
I can again revert to EMUI 4, the main issue with that is the wifi sucks on it. The speeds drop on it where as on emui 5, the wifi is fine.
I gues im not sure does it matter if its test keys or not. As long as it is EMUI 5 then it should upgrade.
On a side note, on thios build I can no longer access Project Menu,, tried the calculator method which didnt work. No dialler installed by default.
For future reference these tablets will show unlocked when locked. They get hung between lock states sort of, it will be locked and report unlocked when checking. Will also give orange state warning at boot while locked. I have a Sigma Key that reports it as unlocked while locked. If you think it is unlocked and getting remote: command not allowed, then is is locked or in between. Run your unlock code again anyway. If it tells you that it is already unlocked it's being less than truthful. UseMy media pad is currently on emmui 5. The keyboard was missing but was able to dowload keyboard from playstore/
Tablet is showing as model number d-01 j and version NRD90m test-keys
Tablet is working fine apart form rotation is now not working. ( using a rotation manager to help with this at present)
Bootloader was unlocked, i get the device waring at the start but i'm pretty sure its locked. Some fastboot commands that i cant run. like flashing twrp again.
I would like to do a couple of things
some guidance would be great on next steps.
- Upgrade to 17.1 - Can i do this with what have at present after unlocking bootloader. Flash twrp, wipe and install the Ziip?
- Will i be able to fix the rotation? Does lineage have asny of dtata files like sensorhub etc...
fastboot oem relock <your bootloader code>
I'm sorry because I can't help you with an answer right now ...
