I have a Z5C(E5803) that was originally able to unlock the bootloader and let me flash ROMs, specifically the Cyanogen ROM that CTXz has been working on. I ran out of power and got stuck in some kind of nasty bootloop yesterday that prompted me to re-flash boot.img and TWRP.
After I did these things I left it charging for a few hours and it was able to boot into TWRP where I then restored it to a backup of the basic Xperia pre-loaded ROM.
This all worked fine, thought I could boot into TWRP and just flash the Cyanogen zip again. I can get into TWRP just fine but I attempt to flash Cyanogen I get an "ERROR 7"
I have since done several wipes, gotten into the bootloader settings by entering that code in the dialer and have seen that bootloader unlock = no. I distinctly remember bootloder unlocking being allowed the first time I installed CM on my device, what could have caused this?
I was able to use it with fastboot anyway and install CM13 again, maybe this was a bug?
When I tried using oem unlock command with fastboot it said my device was already rooted even though I had just restored from a backup, and then I just proceeded normally from there.
use CM13 official Recovery to FLASH CM13.
also i don't think so twrp3.0.2 is out there for z5c. are you using any other variants Twrp? (YUGA ? )
Obtained phone with buggy touchscreen. Flashed CM to see if it fixed it. Didn't. Trying to go back to full stock for return
Recovered stock device via TWRP then installed what I thought was a stock recovery.img, except it wasn't - it was a CM recovery
The CM recovery only lets me boot to recovery or the bootloader - no other options are functional
In the bootloader the FRP is locked and doesn't let me flash TWRP or stock recovery
What should I do to replace the CM recovery with TWRP or stock when the FRP is locked?
THanks

I have just now read your post thoroughly you said that the touchscreenis buggy,is it twrp or in the system
If it's twrp don't worry I too have the same problem in the version I tried eg. 3.0.2.0,3.0.1.0,3.0.0.0
But if it's in system try factory resetting
And change smart power saving mode to performance
But to unlock frp(i suppose you have already unlocked your bootloader) just go into developer options and enable OEM unlocking option
Ok I got the stock recovery back:
I booted into the bootloader and used the local command window to fastboot boot a twrp image from my computer
With TWRP booted (but not installed) on my phone I put in a sd card with a stock recovery image, and used the booted TWRP to install the stock recovery
Unfortunately, I have not figured out how to relock the boot loader, but hopefully they overlook/don't care about that for a return - I did not root the phone
U can relock bootloader in honor5x
I think I have a similar problem. I bought new KIW-L24, I unlocked bootloader, flashed twrp to go to RR Nougat ROM. When I started Twrp to install ROM it said "Comparing tarz 2.2 to 2.5" so I read that I had update to MM.
I went to settings>updater and started update to M331 EMUI 4.0 ROM on the twrp recovery instead of stock recovery. I have M331 ROM now but I can't fastboot the TWRP recovery anymore. It sat twrp installed successful but the EMUI Stock recovery opens up when hitting Vol. + and Power instead of Twrp.
I noticed fastboot menu shows Phone unlocked but it does not say FRP Unlocked anymore. Does that prevent me from installing custom recovery now? Please...any help is appreciated.

Can the frp relocking stop me from flahing twrp? Or is it this stock rom I am on? Do you know if other people have problems flashing twrp on L24 B311 MM update? Could I have caused my issue when I updated to the official rom using the twrp? I didn't think the update would work without stock recovery but it did. I did factory resets but I still can't install install any custom recovery. Can I go back to earlier stock rom?
I followed your instructions and deleted Google accounts and factory restored. I go to bootloader and it says Phone Unlocked but does not say FRP unlocked anywhere. I flshed twrp anyways and although cmd window shows it flashed OK when I reboot the stock EMUI Recovery opens again.
Edit: Now I use adb and mfastboot.exe to open twrp and do a backup. I don't know if I install a different rom if I will able to finally install twrp. I wonder if this 331 stock rom is the problem or FRP is issue here. Never had this problem with my Gold Honor 5X.

Ok. Ive never done this this way. When installing Twrp image it asks where to install? Select Partition to Flash image: Boot, OEMinfo, or Recovery. Do I just press Recovery only?

Select only recovery
ok I installed image, chose recovery, and installed superSU_2.46.zip but it still only boots up EMUI Stock recovery. Unfortunately its stuck in bootloop now so now I cant even adb/fastboot into twrp anymore. Now my only option is holding vol +- and Power to install update from sd card (dload folder). I just dont kmow what FW file to use.

I ended up trying everything. I held volume - and Power to force Fastboot&Rescue Mode. I did fastboot boot twrp_kiwi.IMG. When in Twrp I install twrp_kiwi.IMG (For permanent Install) but EMUi recovery still stays.
I believe the custom recovery is installing but NOT where it needs to install.(Probably a different partition). I noticed a erecovery when I extracted an update file with HuaweiExtractor with does program. I DID get out of Bootloop by applying update from SD card (Force Update Volume - and Plug in USB cable). I rolled the FW back to B130 Emui 3.1 Firmware. I still need to fash Twrp and update this phone now.

Yes I think the FRP Lock is on. It only says: Phone Unlocked. Before it used to say hone Unlocked and FRP unlocked.

Yes I had removed gmail account. I went to settings>accounts and deleted Google and all other accounts. Does FRP Unlock when you unlock Bootloader?

Hi, I am using P600 (note 10.1 2014 Wifi) XAR one
Yesterday I was trying to install magisk all day, but failed all
When I rooted device and instaled TWRP, in TWRP it made error number 1 and it says something like turn to stock boot, so I tried to reinstall stock firmware via Odin, but it didn’t change anything.
I guess it’s a problem with boot.img or the autoroot method I used.
So I tried to use fastboot to install TWRP without rooting, but this time it didn’t boot into bootloader from fastboot, it just restarted the tablet all the time.
So I tried to manually reboot into the download mode, but fastboot didn’t recognize the device then.
When I did it, I turnned on the USB debugging with no mistake since it’s just samsung.
So I booted into recovery mode(It can go into recovery mode without problem)
Then tried option “reboot to boorloader” and it just restarts the tablet again.
I guess something corrupted boot.img or bootloader somehow, while I was rooting or something.
Can I get factory boot.img and solve it? Or when I install stock firmware via Odin does it also fix boot.img and boot loader?
I tried to install stock firmwares and factory reset several times. It didn’t help anything. It did unroot or turn the recovery to stock recovery, but couldn’t get into bootloader.
Can anyone please help me or give me advice to solve this problem?

Hey, I've been using Kangvip rom for the Mate10Pro from this (https://forum.xda-developers.com/mate-10/help/kangvip-rom-t3738379)
It comes rooted with Supersu, and got TWRP up and running.
Now I thought of comming back to the stock version of the phone, and having a problem with that.
First my bootloader is unlocked and FRP is locked, Enable Oem unlocking in Devs Settings is off and greyed out, when trying to flash from the full OTA (from this website)
http://pro-teammt.ru/firmware-database/?firmware_model=bla-l29C432B129&firmware_page=0
Based on my Version BLA-l29C432B129
When I try to flash something, an error appears with Command not allowed, I read that I should relock the bootloader so I did try, but got the error " Root type is risk" so it didn't work.
Same problem in TWRP, everything is SDCARD is encrypted so I can't have a zip or boot image there.
Heard you could system upgrade with inbuilt huawei software, but only allows an external sd card :/
I'd just want to return to stock firmware , stock recovery and unrooted
I will provide as much information as I can!
Kind Regards Felipe
Title.
After playing around with root and some custom ROMs i wanted to return to OOS, I had a few troubles doing that but eventually I succeeded.
I still wanted to have root access though so I tried going to flash TWRP, but was met by the message "serial_mismatch" followed by a system reboot.
This is persistent, regardless off physically trying to boot in to bootloader or through adb.
Fastbootd works, I can flash stuff with success but it seems like it doesn't actually flash since I can't boot into TWRP after flashing it in fastbootd.
I tried mtkclient, both on windows and on livedvd, my device gets found but on windows I get handshake failed until it ultimately reboots and on livedvd it gets stuck on "trying kamakiri2" endlessly.
Also, my safetynet check fails, even though I am on stock everything without root!
Any thoughts on what I can do here?
All help is greatly appreciated.
Hi there, what version of OxygenOS are you currently using?
Currently on 12.1 latest update (DN2013_11_C11). I tried the downgrade packages but as I can't access recovery or fastboot I can't downgrade either.
Please try this method: https://community.oneplus.com/thread/1596759 After downgrade you will have option to relock your phone and safetynet should pass. Let me know if it helped.
Thanks, already tried that but it fails to rollback as well
