Has anyone re-locked their boot-loader and if so is still possible to flash custom ROM's after doing so?

Relocking bootloader means your device required to have everything stock, (recovery, system, oem, all partitions), otherwise relocking will fail.
On stock recovery/after relocking,
you can't install/flash custom stuff. You will have STOCK only...

Hi guys I'm considering to purchase the Z1 beocz I lose my precious Xperia S a week ago :crying: (very very sad, really love it)
As I'm those type who will definitely root the device and probably unlock it some time later, I really care about the camera problem.
I read the the DoomLord thread which told us to backup the "TA" thing before unlocking the bootloader, so we can restore it and have the camera working again.
May I ask what the "TA" actually is?? how can I backup that thing??
So after I retore it, is the bootloader still unlocked??
If i screw up the TA thing, can I relock the bootloader and save the camera by the official repair function in Sony Update Service??
Sorry I'm noobish but plz explain these things to me thank you!!
BTW, are there something i should consider before i buy the phone?? Is it the right time to buy it??
thank you
Its a partition on the device called trim area.
There is a thread about backing it up and its very easy to do.
If you do not have a TA backup then relocking the bootloader will NOT fix the camera.
Also, do not restore someone elses TA it will hard brick your phone

How if I repair the phone with update service after relocking the BL?
And after I restore the TA, is the bootloader still unlocked??
I'm wondering if there's possible to keep both bootloader unlocked and the 20mp camera working...

Restoring TA relocks the bootloader
There is no way to have an unlocked bootloader and working stock camera
I'm getting a little confused!
After rooting + custom recovery + custom ROM, can I restore my TA to get the camera back? Obviously would like to keep root and the custom ROM.

Depends on whether the custom ROM requires an unlocked bootloader. Some custom ROMs don't need your bootloader to be unlocked. So that means you can still have root + custom recovery (which don't need unlocked bootloader) + custom ROM, and your bootloader is still unlocked and your camera is still working.
But if the custom ROM requires an unlocked bootloader, then restoring the TA will result in the bootloader being relocked, which means your ROM no longer working.
Someone correct me if I'm wrong.

Basically you can only use roms based on official firmware for now (and have a working camera) afaik. All the roms in the original development area (based on AOSP, custom kernels) required unlocked bootloader and as a result have a non-working camera.
Guys i want to install this
http:// http://forum.xda-developers.com/showthread.php?t=2470806
But i have a locked bootloader
Please tell me how to do this
And if i have to unlock the bootloader
How to, without sony knowing.....
u can't...
the only way is to make a backup of your TA partition, unlock your bootloader, and flash a custom kernel. then if you need to send it back for warranty just flash the stock kernel, restore your TA partition and it will be as tho your bootloader was never unlocked
Re-lock BL

Is that really that easy ? As far as I remember relocking other devices (sola) needed more tinkering to do that.
My gf has HTC One with latest stock T-Mobile US ROM, unlocked bootloader, is rooted, and has TWRP. T-Mobile is about to release an OTA (source), and I am wondering how to go about installing it. AFAIK, stock recovery is required, AND the bootloader needs to be locked again. If this is the case, re-rooting will require unlocking the bootloader and thus doing factory reset? Is there a simpler way to do this?
Stock recovery and preinstalled apps needed
Bootloader locked not needed
There are many posts written about this read them first

FYI I have actually tried running an RUU on unlocked bootloader with stock recovery, kept failing until I relocked the bootloader...
So I unlocked(htcdev) and rooted(twrp) and now I wounder if I should re-lock for security? I read that the boot-loader could have an authorized os list. Since both the system and recovery are os's would a re-lock put twrp out of control?
Thanks
I'd like to know this also. Fortunately relocking seems to be easy.

Never relock with custom roms or custom recovery still installed on your phone, this will result in bootloop.
Only way to stop this bootloop will be to unlock again but unlocking the bootloader require the stock recovery to be installed.
So with custom recovery installed and bootloader relocked = bootloop = can't unlock again. You'll have to reflash the whole firmware in ruu mode to get back the stock recovery over the custom one and then you'll be able to re-unlock to stop the bootloop.
So short answer, don't relock when not 100% stock
Ich, thanks! Glad I asked first instead of taking the chance..

Is there a procedure to unlock the bootloader, root, uninstall some of the T-Mobile apps and make a few changes, then unroot, and relock the bootloader?
Everything I've seen so far requires re-flashing everything back to stock, I was hoping to avoid that. (Obviously, the bootloader and recovery would be stock when I'm done, just not the system)
The locked bootloader will not boot a modified system partition. As such revert to stock is required. Question is still open on relocking the bootloader post MM. After MM the unlock is visible on the boot screens where previously it was not. This would be an instant giveaway on any warranty claims.
Thanks, that's what I thought but I wasn't sure.
