You do not need to relock your bootloader to receive OTA ..

Ok thank u for the answer. so i need only the stock recovery? Or am i wrong?

You need recovery compatible with rom came from..
For example ; if u are on 127 and u wanna go back to 120 u need to flash 120 recovery first .. then flash 120 ROM

Do I need stock recovery to CHECK if updates are available?

Well, you can manually check it will pops up once huawei sends OTA ..
u can have CWM but u wont be able to upgrade.. you will need stock recovery for update OTA..
to be honest custom recovery is technically useless for us bcos no custom roms are avail. it just good for rooting.. nothing else..
System knows when phone has been rooted ... here below

Thanks for the information (and pic). Will flash stock recovery back only when/if there are updates.
CWR will be useful if we (like me) do something stupid and then restoring from backup.

[Guide][Receive OTA after root][keep apps/data][GT-I9500][5.0.1]

a lot of users are having this problem and if you want to receive an OTA you have to flash the stock unrooted firmware that will cause lose of data.
this guide will show you how to receive OTA again without losing your stuff
This works on GT-I9500 ONLY! (Lollipop 5.0.1 Recovery)
This also should work on any other model, but you have to replace the recovery with your model!
Steps:
1- Go to SuperSU and scroll down to "Full unroot" then reboot.
2- Download This file to PC and extract it.
3- Go to download mode by pressing the power key + home key + volume down key at the same time, then press volume up.
4- Flash the file via Odin (AP) or (PDA)
go to check the system status, you will find it Official
you can now receive OTA.
Q&A:
What is OTA (Over The Air)? Its an update which you can receive over wifi or mobile data.
What do i get from OTA? Well, if you root your device you wont be able to receive an update again, unless from flashing firmware via Odin.
- Why im still on custom status? Because you modified your system.
- What kind of modifying? Installing busybox, editing or deleting or changing any app or file system.
and some times xposed.
- How do i restore the old app? You can restore them by flashing firmware or by restoring Nandroid backup.
- Then what is the use of your guide? Well my guide helps in first place the rooted not the modded onces.
and always do Nandroid of the original system apps+data
you are still having your apps, data, pics, vids, etc...
you can root again at anytime.
check my thread for rooting if you want
im not responsible for any bricks
thank you...

Your welcome!
Hi there,
Thanks for the guide, just thinking you may want to say what option in Odin to put the file and what OTA stands for, for the noobs.
Just a thought.

At some point the update maybe canceled, because the update checks for the apps before the installation, always do a backup of your phone then remove what you want, after you want to update just restore the system folder from the backup

If you can see the stock recovery then check the SuperSU app again and maybe you are having a custom kernel

So i need to unroot it as well ? Anyway flashed via odin original stock russian lollipop rom just to check for any update and the flashed twrp and rooted it back. Just that it takes 10 mins or more to do all this. Thought your small flash file would work .

[Q] ROM Update on CWM recovery

I have the MT7 TL10 international. The phone is rooted, BL unlocked and CWM installed. Today I received notification that an OTA update on B123 is available. I think I've read somewhere that the update will not work with CWM so I have to go back to stock recovery. I know how to do that but I just want to confirm with you experts whether or not IT is needed.
And in case I go back to stock recovery, do I just have to flash CWM again after the ROM update and it's all good again?
Thanks in advance for your feedback-much appreciated

Dear Simona,
thank's for your reply. If I get you correctly IT is needed to go back to stock recovery before flashing the OTA update.
But what about my second question. If I flash CWM after the ROM update, will the phone still be rooted, BL unlocked, CWM recovery and SU installed?
My apologies if this is a silly question, but I'm not an Android expert - just an user....

I removed it with the "full unroot" function in Super SU.
The problem is I don't want to flash everything because it will remove my stuff which is what im trying to avoid.
I might just backup everything and call it a day haha.

Move to Q/A section .
U cant install recovery like that , u have to be at 4.4 then root it , and flash recovery , then flash Lolipop rom . Only like that u will be able to go in recovery and flash what ever u like . Search forum before posting . But first of all u must flash KDZ file to your phone to get rid of bootloop .

Your GP2 must be rootet.
Download this Package and unpack it.
Enable USB Debugging on GP2
Klick exe in the unpacked zip Folder.
Accept the Superuser Question on your Display
and Press 1 on your Pc Keyboard and wait to finish the Process.
You have an Recovery (chinese) on Lollipop Software.

D838 Recovery
thanks, friend. perfectly ease, in 2 minutes recovery on English installed...
Now I canbackup and be free in customization. But, not too many things to try. My opinion is that we badly need cm 12 to extend life of this mighty and great phone.
thanks again, later I will install your 20d rom but not expect much new... And probably xposed...

Important is the Recovery and root works.
Another Question,works your cam with the english Recovery?

So you don't know who made this recovery? I would like to know if this is using a KK bootloader or a LP bootloader.
If I install chinese recovery? How to go back to stock recovery when needed?

Where can you find what?
And yes, to flash any type of root zip you need TWRP. I personally prefer MagiskSU.

Need Help!
The front facing camera is not recognized by the application such as htc camera app, google camera. I don't know what the problem is, hardware or software related. I did a factory reset. Would be glad if there is a solution. Ps. Is there a utility for PC to diagnose hardware via usb cable?
