Need help

Hey,
Just wanted to know if I could relock the bootloader on a HTC One because since I unlocked the bootloader and rooted my HTC One I am unable to update the device to Android 4.2.2 even though i have received the update it download's the update completely but doesn't continue with the installation process... Also on the screen that comes up when you continually hold down the volume down and power button at the same time I see a message that says TAMPERED ... so if you could please let me know hoe I could relock the bootloader or even help me in a way you think I could resolve the issue it would be great ...
Now I also do not want to unlock the bootloader nor root my older HTC One X because of this issue... But if you think its not an issue please provide me some link/help ...
Thanks in advance :good:

you need stock recovery and stock kernel for the update to work,
or just follow this thread: http://forum.xda-developers.com/showthread.php?t=2423683
if you are on 4.1.2 at the moment i recommend you S-OFF the device before updating, because you will not be able to later

Need a lil help here. Im currently on firmware- 10.4.1.B.0.101 with [Root & XZDR] http://forum.xda-developers.com/showthread.php?t=2643898 <-- via this method.. all Works sweetly.. Problem is that i want to unlock my bootloader. Ive checked in the service menu, unlocked bootloader is allowed.
I am currently trying to unlock bootloader with latest version of Flashtools(unofficial way).whilst phone is on, i connect cable, startup flashtools, it detects device. Then i click on lightningbolt icon, to unlock bootloader. menu comes up asking to remove cable, power off phone n goto flashmode.
When i get to the part where it asks to select my device, i click on xperia z. And i get a FAIL message saying i cannot officially unlock bootloader?? Do i need to be on stock .244 firmware or stock kernal to unlock ? Or am i going through it the wrong way. main reason i want unlock bootloader to install cyanagen mod11 nightly.
Thnx

[Q] Does Stock Rom needs Locked bootleader?

Hello. I want To flash 4.3 Stuck Rom For my Xperia TX. Its Unlocked . Should I relock it Or something else ?
please tell me

Unlock is Unlock bootloader or unlocked to work with all sim?
If you have unlocked bootloader just do it next step:
If you want to flash it with Flashtool, you don't need to lock your bootloader.
If you ask for update with Pc Companion or Update Service, furst lock your bootloader and then try.
Best regards.

[Q] Cannot Screen Mirror after updating to Lollipop

Hello guys,
My Xperia Z1 used to be able to screen mirror to my Samsung Smart TV when it was still in Kitkat 4.4.4 (firmware 14.4.A.0.157 i believe). However, after updating to the current Lollipop 5.0.2, the screen mirroring feature does not seem to work; everytime i try both devices would get stuck in connecting for a while and then Z1 would disconnect with the toast message: cannot turn on screen mirror.
Now, the interesting thing is, back in 4.4.4, i rooted the phone using the method of flashing and rooting an older kernel (14.4.A.0.108) with EasyRoot , and after updating to 5.0.2, i lost root access. One of my friends has the exact same Z1, the only difference is that he never rooted, and after the update, his Z1 can still screen mirror just fine.
The question is: Has the rooting process i used affected the screen mirror feature in some way? And more importantly, does anyone know how to fix this issue?

Is your bootloader unlocked? After unlocking bootloader you lose the DRM keys from your phone which in turn means you lose features like ScreenMirroring, BIONZ image processing algorithms and X-reality. So these features won't work on a device with an unlocked bootloader.

Well no, my bootloader isn't unlocked, which is why i find it weird that while TrackID still works, Screen Mirroring doesn't.

I had same problem but exact opposite, it never worked on 4.4.4 on samsung tv but now on 5.0 it works ! on sony tv it has always worked !
