In my attempt to get it working, I've made it worse. While installing the ROM, I noticed that it said this:
-B356 ROM successful installed
script succeeded: result was [
E:unknown command []]
Updating partition details...
The unknown command part was in red, as if it was an error. Nevertheless, it didn't work after trying many times (didn't work = didn't flash the ROM, it was all just stock Chinese ROM). So when you (and others) talked about "formatting" and "deleting all data", I thought maybe you meant the "Format Data" option in TWRP, so I did that. I might have also been that under "wipe", I selected everything: Dalvik / ART Cache, Cache, Data, Internal Storage, System, and Vendor. Then I flashed it. I guess that was stupid....
Now it won't even boot. After the "honor" boot screen, I get a message saying:
Encryption unsuccessful
Encryption was interrupted and can't complete. As a result, the data on your phone is no longer accessible.
There's a long paragraph more after it, but basically it tells me to do a factory reset, and then has a button that says "reset phone" under it. When I press it, it just boot into TWRP.
When I try to install the ROM again, it says the same "E:unknown" error, and then after the "Updating partition details..." it also says:
Failed to mount '/data' (Invalid arguement)
...done
I reboot... and same "Encryption unsuccessful" message. I even restored a previous backup I had of the stock system before I started doing all this flashing, and that didn't work either, I still get the "Encryption unsuccessful" message after rebooting. Did I just brick my phone? Please help.
