just go to essential website in the dev section and download the stock rom of your carrier then unzip it and do the flashall bat. then if it's all good you can relock your bootloader.

Hii
I just got my Z2 rooted with this method
I just followed the steps
http://forum.xda-developers.com/xperia-z2/general/guide-how-to-root-xperia-z2-android-5-1-t3253878
Just one question
My bootloader sayz unlock not allowed...
Can I now flash TWRP or not?
Or is it just that I can not flash kernels??
I dont understand what is diffrent with bootloader locked and unlocked
Mine as I have read is locked forever so I dont want to brick my device or something...
Some advice about such bootloaders and what I can NOT DO would help me to understand
Thanks in advance
EDIT 01:
I just have followed the link in that post where I have rooted the phone
And just got TWRP installed as my recovery
So just to let you guys know evan dual recovery works fine with L5.1.1.
Just to say I have LockedBootloader
So guys please advice me for further
What restrictions do I have with the LB in diffrence to Unlocked BL
Can I do exact the same flashing of things like they on unlocked BL or not?
What should I be carefull about
Please guy give some info
1- With locked bootloader
you can only flash sony stock based roms (you can flash miui rom as there is a version with sony stock base).
you cannot flash cyanogenmod or custom kernels and any other rom.not based on stock sony.
2- with Unlocked bootloader
You can flash any custom rom or kernel for xperia z2 including cyanogenmod.
But you will LOOSE your DRM keys if you unlock your bootloader which will degrade the camera quality and xreality engine...

You cant accidentally unlock your BL and if it says it cant be unlocked Im afraid it is locked forever. There is no any way to unlock it AFAIK. If you have root, which it looks like you do, you can install TWRP by downloading an app TWRP manager from the plat store, give it root permission and in Install section find your variant of Z2 and let it doo its thing. It will automatically flash recovery.img and reboot and thats it.
Now you can flash all [UB] as unlocked bootloader marked roms, but no custom kernels and AOSP ROMs.
In my experience, if you try to flash something for LB it will just produce an error and you can reboot your device normally without any changes.
Thanks guys !!!
No its all clear to me

Hi, i have a xt1621 non plus, i've unlocked for rooting Marshmallow, but now i have the Nougat Stock rom 25.93.14-4 via stock recovery. I've read in other threads that i need the latest stock rom for my device to re-lock the bootloader. I can't find the rom.
Now, when i downgrade to Marshmallow, the update to Nougat 25.93.14-14 appears, but is possible to re-lock with the OTA update?
Regards.

No, you need to flash the images via fastboot and then run the lock command. There are explicit instructions on this forum.

Hi guys I have the retus Moto g5 plus
And I'm on NPNS25.137.35-35
I flashed TWRP and a few roms but would like to return to stock and Relock the boot loader the problem is I have reflashed the stock rom with NPNS25.137.35-35
And it works fine but the fastboot oem lock fails and says still requires signed boot or something like that.
Can anyone help or give me a step by step with commands to try ? Am I screwed because I installed TWRP ? I can learn to live with unlocked bootloader if I must but the OCD in me wants to lock it lol
Thanks for any help.
I was able to relock the bootloader should have searched the forum a little more before i posted thanks anyway

You cannot downgrade any stock ROM. Here in your built number extra S stands security patch and it not 35-35 its 35-5 (5 Indicated May security patch). If you want to come back on stock ROM with OTA updates then First install any Custom ROM on your device then Flash with Stock ROM Brazilian NPN25.137.15 (Indian Variant) Download from Firmware site and flash it using "fastboot oem lock" commands. Search for Installation of Custom Rom you will get it.

How did you do it?
I'm unlock bootloader with official unlock tool. Can I relock bootloader ? or flash Stock rom (WW_21.40.1220.2171) ?

Edit: Sorry my bad English.
I have a Verizon Galaxy S5 running Lineage OS, and I wanted to restore back to the original ROM or in the best case a debranded ROM. If I flashed the original Verizon ROM will the bootloader relock as I want to go back to stock but want to keep the bootloader locked + be able to access TWRP, but I will probably have to reflash TWRP.

When it comes to the Galaxy S5 Devices (specifically), the ability to unlock their bootloader is determined by their CID (there's either the CID11 & CID15) and those can never be changed.
With that stated...
If that specific device (you're asking about) already has an unlocked bootloader, you will be able to unlock it again after flashing the Stock Firmware.
I hope I had explained this okay via text...
Good Luck!
