Are you are using cm on v20x? Then making stock wouldn't recover your warranty cause you have surely unlocked bootloader, which can not be reverted. If you still want stock, then just do a kdz flash using KDZ flasher not LGFlashTool.

This will make full stock exept for Bootloader. Then just do a factory reset.
I hope you know, how to find correct firmware.

I guess that I need to flash original bootloader first to get S/W upgrade mode. In fastboot mode phone is not detected.
About bootloader, I can relock it. Also it depends on the laws of each country if I lost warranty by unlocking or not.

This not detected thing looks like a CM bug, happens to everyone maybe. Don't worry about that. Just open and reinsert the battery. S/W mode will work then. This happened for me too.
Can you please tell me, how to relock successfully? And can I unlock again after relocking?

Still no success in getting to S/W mode.

How "Finally"? Reinserting battery or flashing bootloader?
So, you are trying to relock? Please tell if you succeed.

S/W mode.
I'll send it into the service first with unlocked bootloader and only if it gets rejected I will try to lock.
I have some dust under the screen so it can be hardly affected by any software changes.

[Q] i cant flash stock B136, Update fails at 50%

hey xda world,
first this is my first post ever on this forum and i cant hold myself of being amazed from how helpful and smart the people here,
my case is kinda hairy so bare with me
now lets get to the mess, so i got yesterday myself a p9 *EVA-L09C02B123/Vodafone*, unlocked its bootloader then installed twrp and root, after doing the process i tried to lock the bootloader because of the annoying message at the bootup, but i couldn't because of an error from fastboot {Root type is risk}.
i looked up the error around the interwebs and xda ofc, and somewhere i found that relocking can only be done if all the partitions are oem/stock, so i decided to get rid of the twrp and flashed back the default recovery from the SRK Tool and still couldnt relock it.
then i started to look for stock roms and couldn't find a stock for the L09C02, so i tried the dload B136 and it failed at 50%, knowing that oeminfo dictates which version the phone should get, i got the C432 one and flashed it using twrp, did factory reset and i noticed the vodafone boot logo being replaced by the default huawei, at this point the build became *EVA-L09C432B123* and tried the b136 dload and still no luck and failing at 50%.
please help ! :crying::crying::crying:

Welcome to xda
Does your phone still boot? And what is it you are trying to achieve right now? Relock your bootloader?

my phone does boot, and yes i want to relock for the reason i might want to sell it but having that boot message is kinda cringey for non power users.
also an update on the case, yesterday after posting this thread i downloaded an update zip from this post http://forum.xda-developers.com/showpost.php?p=67122856&postcount=47
then i flashed the zip using twrp and succeeded, now the version is L09C432B136 but still no luck locking the bootloader.

Possible bad download? Try downloading the whole stock rom again.
Any error messages?

this is not a fix to lock the bootloader as that is hardware level not software level. Use the tool DC-Unlocker or SRK Tools, look on the other threads under Huawei P9 and you will find these two options to lock the bootloader again. I have already done it on mine after de-branding and network unlocking my (what is now a....) EVA-L09C432B136

If you can boot and have the correct version, I'd say try a factory reset, download that full stock rom again and try flashing. I don't see why that shouldn't work. Unless there is something different hardware wise about those branded ones...

first must remove root via super su, then flash stock recovery then relock

I get a "root type is risk" when i relock with SRK Tool, any idea?

Actually AFAIA flashing the stock rom will relock the bootloader.

External sdcard

i had an issue trying to update from B136 to B166 and i ****ed up everything
Only solution i found was to dload with stock rom B136 provided by PaulObrian in dev section, successfully, and guess what ? bootloader was locked again

can the G4 H811 bootloader be relock?

just as the tiltle says cna it be relocked after unlocked? like if you get it unlocked, then you get hit by bootloop issue. can you like relock it then flash stock firmware? and send it back to LG or tmobile for repair. so relocking will remove the bootscreed info about unlocked..
anyone .? can confirm?? would love to see video of it.. relocking it.

yes, use the same command you used to unlock it - just change unlock to lock
ie: fastboot oem lock
use: fastboot getvar oem to check the status

If you have a custom boot loader then I think you are out of luck like I was. If you are on a stock boot loader then I don't know.

mines its locked.. dont want to void warranty, only if i could know that even if it bootloops and i can relock it i would unlock it..

So my scenario is that I unlocked mine and flashed TWRP to it. I then relocked it and that screwed me up bad (don't know what I was thinking). Anyway after I fixed it I was no longer able to relock it and when I got the next OTA I was back to my screwed up state and without thinking I followed my old steps exactly and restored the previous version of MM and never went back to 20o. One week later my phone is now a paper weight and I had to buy a new one.

i dont think relocking can damage the phone. what i think is this, you said you got ota. was that 20o? if so you update to that 20o, then downgrade you bricked your phone. as you stated restore previous version of MM never went back to 20o... you bricked it.. not relocking it... 20o its V3 of antirollback.. previous version of MM its 20i thats V2 and so its LP 10n. both V2 you could u[pdate or downgrade your phone from 10n-20i only... you brick it...

Trouble rooting H811 on the 20i update

Ive done a bit of reading and the information seems to be in a few different threads and doesn't specifically mention the 20i update.
So here are my questions:
Can I root and install twrp without BL Unlock?
Can the BL be relocked? (Ive seen people stating it can and others say its impossible)
If TWRP cant be achieved w/o BL Unlock, can Xposed be installed without TWRP?
Im trying to avoid BL Unlock as I cant return it with an unlocked BL should I need to.
All I want is root, xposed and Viper4android
If I can unlock and relock BL then I'd be fine with that.
Id appreciate if all links and responses are applicable to the 20i update
Ive included a screenshot of the SW Info

root with locked bootloader only on LP10n you can downgrade from 20i to LP10n only as they both antirollback V2.. the new 20o its V3.. so youll be stuck there.. in LP 10n yes you can root with locked bootloader using systemroot injected...
on MM to root you must unlock bootloader and have a kernel that supports systemless ..
so quick answer locked bootloader.. only root no twrp and must be on LP10n.
MM you need bootloader unlocked..
according to some guys it can just by changing command relock.. funny no ones has made a video of it relocking.. as the same some say it cant some say it does.. i think only H811 can..
yes on LP 10n you cna flash xposed .. with flash fire.. thats the only zip that installs .. the rest like mods wont install.. funny thing xposed does.. the mods i do them manually placing the files to their folders and changing permissons..
my question is.. if unlocked .. and get hit by bootloop can we relock it even that phone has ILAPO o bootloop issue... as it needs to boot it reboots... so its it need it to boot phone to recock it.?
if you unlock could you relock it flash stock fimrware then send for repairs..? thats what i need to know.. so i can unlock it..

My last device has an unlocked Bl on MM10i(Ithink) and I downgraded to lp10n and the Unlocked BL message at boot went away. However Im not sure if it was relocked by downgrading or the message stopped showing.
Currently, the phone is completely stock w/o root. You're saying that I should downgrade to 10n, root and flashify Xposed.
If I do take this approach can I get MM and retain the root and xposed?

if you want root with locked bootloader.. yes LP 10n do the inject low effor root and flash xposed . not sure about flashify , i used flash fire..
no you wont have root or xposed... fot that you need bootloader unlocked on MM.

Yes I'm on 20i. However I'm not sure if I can downgrade on this version without tripping the QFuse.
And in regards to the previous device, I think the BL might still be unlocked. Ive read somewhere that the message only shows up if you're on MM.
It wont show if your're on LP even if its unlocked. Im not sure tho someone would have to confirm that thats the case.
If in fact the BL is still unlocked but its just a matter of it not being displayed at boot in LP, I imagine they might be able to tell when they use whatever software they use to wipe them when refurbishing.

MM20i and LP10n are V2 you are safe to downgrade. you can only go from 20i to 10n or 10n to 20i.. if you update 20o youll be stuck there..
okey thanks then maybe it only shows in MM do to the systemless feature blah blah blah.. and on lollipop you can get past that security...
all i want is to know can i relock it even with phone in bootloop issue.. thats what keeping me from unlocking.

How to go back to stock and relock the Bootloader?

Hello
i have to sell my device so i want to get it to stock again.
My current Setup:
Bootloader Unlocked, Stock Recovery, Rooted with Magisk, Stock ROM 9.0.0.283
What are the Steps to go Back to Stock and wipe everything?
Ive read that if the bootloader relock again it is not able to unlock the second time? Is this correct? I want to get the Unlock Code to the person who buy it but if its real, he cant use the code anymore..
anyway is it possible to do the job with the Stock E-Recovery in the current state of my phone? Without bootloader Relocked? Or is it necessary to relock the bootloader again?
Thank you very much

Ask the buyer if they want it locked. Personally it wouldn't be worth my time if it couldn't be unlocked again. Better to check first..

If you want to lock (not relock) bl justdownload your adequate firmware from androidhost.ru and flash fw using Usb-otg method.
You can unlock/lock your bl using unlock code anytime you want (provided you haven't changed your mainboard in the meantime).

I thought you wanted to go back to stock. I've already gave you solution to bring back all the way stock.
I m not sure if it's even possible to re-lock bootloader using fastboot when you're on pie.
Bootloader status re-locked still means your warranty is void.

Even with the dialer code method.. same..
I'm not able to get it to stock.
I've tried the Huawei suite on PC and phone in fastboot mode..same..massage this phone can't be reset or so..
What can I do next?
Current state, halfway working phone that's boot into os 2 times from 10 reboots.
