Flash fastboot rom with clean+lock. Then boot your device and set up. Then unlock it

Are you suggesting him to flash a complete new rom which might cause loss of data

[Q] about losing root

Hey everyone, I've been using my hox+ rooted for some time now, never flashed a ROM and was wondering if I update to the new att software will I lose root?
Yes. Just make sure you have a custom recovery and flash the root installer zip. Or if you have TWRP, after a the flash, it will ask to install root.
Hey thanks for the response, I'm running twrp 2.4 the thing is I don't know whether to to let the phone update through its regular way of updating or do I flash this http://forum.xda-developers.com/showthread.php?t=2235248, the problem with flashing this is I don't
Know how to flash boot IMG. Sorry I'm a noob any help would be greatly appreciated.
Use this command in fastboot.
fastboot flash boot /location/of/boot.img
If your bootloader is unlock and your phone has a custom Recovery, the official AT&T update won't install on your phone. If you want the update, or you wait for a custom ROM with the update to be available, or you relock bootloader, and flash the latest RUU to recover the original state of your phone. Then you can still unlock with the same token and install a custom recovery to root your device.
Thanks much fellas, you've been a great help!

I'm not as knowledgeable as the devs here, but you could try unrooting and then unlocking the bootloader?
Unrooting has nothing to do with it. Have you tried this?

Xperia Z5C won't root

I really don't know what is left to do, I always end up with a bootloop and have to repair my phone with flashtool. I have tried flashing twrp by adb/fastboot, temporarily booting to twrp, flashing different twrp files after repair.... I always get boot loop. Help please :/
Once I had my phone rooted by oneclickroot support, then I started to get play store crashed constantly. Once I booted to recovery and when try to reboot, got a bootloop. I tried to flash a new rom, so found a stock rom for Z5C and flashed it by twrp. But after a reboot I lost the twrp recovery this time. Then I tried to flash the recovery myself using abd, following the basics; fastboot flash boot boot.img/recovery recovery.img But I again stuck into a bootloop. Repaired again... I thought flashing a custom recovery breaks the phone, so I decided to just boot the recovery and install supersu. but again a bootloop in the end.

I have flashed the lastest stock ftf by flashtool, that is what I do after everytime I brick it while trying to obtain root. And if you mean switching to another user, yes it does.

Flashed the rom and phone is not booting [only mi logo displays] help!

I was on nitrogen N rom. Then I wiped the data, cache etc and flashed latest firmware and then flashed the Viper os and gapps. Then booted the phone to os. But it just blinks the mi logo. Even when I try to go to recovery, only mi logo blinks.
Phone is not even charging.
Only Fastboot mode wrks. But that too phone is not detecting in laptop on windows 10.
Kindly help me.
Your phone has been soft bricked and there is nothing to panic about this happens while flashing the roms as sometimes the flashing process is not done successfully or executed successfully ..So the solution for this is to flash the fastboot rom using the mi flash tool and to flash the this rom you need to open fastboot mode and then the edl mode..in this edl mode the phone will be detected by the mi flash tool and the flashing would be done ..
Refer this link for the process

Hope this solves your problem

Probably because you had an unofficially unlocked bootloader and because you flashed lastest firmware it is locked now. If i am right about your problem then the following is the easiest way out.

No.. Unlocked the bootloader officially. When I flashed the firmware, it might have relocked the bootloader again. And also cudnt open recovery. Either way, it just blinks the MI logo and power off.
When I tried to unlock the bootloader again officially, it stucks at 50%.
Dono wat to do exactly now.
P. S. Tried that method in that thread link you gave. It shown as success in the flash tool. Den tried to flash TWRP in fastboot, it shown as failed.

Yes, you can flash stock firmware in edl mode when bootloader is locked. And you need to unlock bootloader If you need twrp to install custom rom.

This way always works for me. Did you tried flashing twrp again? Maybe you can try once more. Or you might have done something wrong. Bdw can you tell me what exactly it showed when you tried flashing twrp??

I can tell you how to check if a particular firmware will lock it. Download the zip and check if it has emmc.appsboot.mbn file. If it is there then your bl will get locked.
To flash the firmware without getting locked, you need to remove that file from the zip. You can do that with any zip app. Just select it and delete, and flash the zip?.
PS: All the above is only if you have unlocked unofficially. Else any firmware will do. Just be sure to get the latest one.
