[Honor 5C Questions & Answers] wetchko:
Hello everyone, it's my first time writing here, but I’ve tried everything, searched everywhere, and am desperate for help.

I screwed up big time while trying to flash a custom rom on my nem-l21, as I successfully did before with my xiaomi... So what I did:

I managed to unlock bootloader with dc unlocker. Then I got stucked flashing twrp with adb tools. Everything was looking to be fine, no error messages, “flashing successful”… But, I was never able to boot into flashed twrp. Always got stuck on “your phone has been unlocked blah blah. Your device is booting.” It never booted, not in twrp, nor in stock recovery. I tried different versions of twrp from different sources, always same result (flashing successful, booting into recovery not). Booting into the system was fine. And then I made that horrible mistake. Oh, how I wish I didn’t!!

I read on some website, that you are supposed to flash the twrp as boot.img, not as recovery.img. Seemed illogical and stupid to me, but in the end I tried it. Of course, this just bricked my phone, with no possibility to boot. After hours of googling, installing, trying and crying, I managed in the end to flash back stock boot.img. But at that time, I didn’t know my build number (b359), and I flashed boot.img b351. So now I have a phone which boots into the system b359 with boot.img b351, but with lot of errors.

- developer options, security options, display and factory reset option doesn’t work and just crashes. Therefore I am not able to flash the correct boot.img b359 or anything else at all from pc, no way to enable usb debugging and oem unlocking. Adb devices → nothing. I am able to use fastboot (fastboot devices sees the phone), but when try to flash something, I get error “command not allowed”. Also I can’t enable unknown sources installation, which bothers me a lot. And I can’t make factory reset to restore the crashing settings. Also I can’t change display timeout, and original 30 secs is super annoying.

- I am not able to uninstall even apps installed by me, always just restarts system UI and app stays.

What I tried so far:

- flashing correct boot.img from pc, not working because of dev options crashing

- go into recovery, but stock one is overwritten with unfunctioning twrp, always just get stuck on “your phone was unlocked blah blah… your device is booting now”, but it never does, have to hard reboot

- go into huawei erecovery, which is working, but when I try to resolve problem from there, always ends up with errors and crashes

- connect to pc and use HiSuite, system recovery tool here always says “no problem detected”

- updating to b361 through system update settings, always crashes on 5% and sends phone into “your phone was unlocked blah blah… your device is booting now” error

- downloading the proper b359 as and update.app file, put it in dload internal storage → same error during update, put it in dload sdcard → same error, no matter which way I use to start the update

- boot into twrp or stock recovery.img through fastboot without actually flashing it, anyway error “command not allowed”

- do factory reset or update through dial codes (i.e. *#*#123456#*#* …), nothing worked

My pc is windows 10, all drivers up to date. Using powershell as an admin. Am an idiot for not making backup of the phone before I started...

So, now I have more or less functioning phone, but I can’t uninstall any apps at all, can’t install from unknown sources, can’t do nothing from pc, can’t make any update, and lot of important settings keep crashing.

I can use the phone like this, but if somebody could think about some solution for this ****ed up situation I got myself into, I would be grateful to him/her for the rest of my life.

Sorry for a long post.

Thank you in advance and have a nice day :)
