Reverting to stock/relocking bootloader - ZTE Axon 7 Questions & Answers

Hi, I couldn't find any guides or posts with instructions on returning to stock software with bootloader relocked. I just want to avoid bricking my phone beyond even the revival capabilities of EDL and tenfar's tool.
I'm currently on LOS14.1 with my A2017U.
Thanks in advance

You can back to stock recovery by:
Wipe and flash stock system proviced by DrakenFX . After flash, it will return to stock recovery by default

How to root OxygenOS 3.0.2

Hi
I am new to the OnePlus 2. When I bought it, stock 5.1.1 installed, I downloaded and installed the latest Marshmallow stock build via an OTA update. I then followed the official OnePlus video guide on unlocking the bootloader and rooting the device. I successfully unlocked the bootloader, flashed TWRP and then went on to flash SuperSU. Unfortunately, then device did not reboot - and I was soft-bricked, stuck on the boot animation. I am not sure what went wrong here.
In order to un-brick and recover my device, I downloaded the latest Marshmallow OxygenOS 3.0.2 zip from OnePlus. I was able to get this onto my device and I flashed it successfully in TWRP, and all is well.
My questions are:
1) Having flashed the latest stock, Marshmallow OxygenOS 3.0.2, will my bootloader still be unlocked?
2) Will I still have TWRP recovery, or stock recovery?
3) How can I successfully root?
Thank you in advance
I already forget what it is looks like when I change from stock to custom ROM.
But hey, here is the guide to help you:
1. use Fastboot command -> fastboot oem device-info
If "Device unlocked: ture" than your bootloader is unlocked. Normally, if you have not yet touch anything, oem is locked. But if you do unlock it, it will STAY unlock unless you use fastboot command line to change back to locked.
2. OP website only show is optional to use official recovery, so I think it is depend on you. Just go and check on it
3. For OnePlus Brand is easy. Just go and download SuperSU 2.74, place into your "sdcard", and flash it.

Hi - many thanks for the reply and information
Just to confirm, question 2: I flashed the latest stock from TWRP to recover from a soft brick. Would that process have flashed stock recovery also? Do I need to check this out by pressing Vol. down and Power buttons on boot?
Thanks again

TWRP will ask you, if you want to disable stock recovery flash, after you flash official firmware.
Rooting the newest stock firmware with the latest supersu from chainfire's website will turn your device into a bootloop.
Here you can find the right supersu for your firmware:

Hello and thank you for sending me the information and links. Flashing the modified supersu worked and I am now rooted
Just a final question please...Before I received your reply I had flashed stock several times and tried different supersu versions. And ended up in bootloops as a result of this. Is this likely to have damaged my device in any way?

New ZE551KL locked bootloader/no root MM

Hi,
I've just got a new ZE551KL (z00td) with a locked bootloader and no root. Since the phone have the latest android 6.0.1 build I have difficulty to root it and unlock the bootloader. I did many research and I think it's really confusing. It seem to root my phone I need an unlocked bootloader but to unlock it I have to root my phone. The last interesting thing I've found for my phone is to flash a pre-rooted system.img & boot.img ( http://www.asus.com/zentalk/thread-80274-1-1.html ) but I also get stuck here since the guide tell me to flash both and I can only find the system.img.
I would like to know if there's any guide to root & unlock my bootloader on my ZE551KL. Thanks a lot!
It's a pain, but you may have to roll back to an earlier version of the firmware...back to lollipop. There are instructions in one of the threads on how to do that. I was able to unlock before the marshmallow update with the official unlock utility from Asus. Once you are unlocked, the easiest way to root is just to either boot twrp.img (previously downloaded and extracted to the adb folderon your computer) using fastboot (lots of threads here with instructions, too) and install supersu.zip. Or if you want to install twrp as your recovery, you can flash it from fastboot, then flash the zip of supersu. If you need more help, I am no expert by any means, but I have done this with my own ze551kl and might be able to give you some more hints.
Personally I would avoid the prerooted images as I had a lot of trouble with them and nearly bricked my phone by trying them out.
Thanks a lot for your reply! That's what I'm trying right now. I'm rolling back to lollipop from an official rom file from asus website. So far, I tried to flash it with stock recovery but it said that I cannot install a older version on top of a newer one. I did an downgrade of the recovery and now I'm waiting for the flash.

Excuse me, how did you do the downgrade of the recovery? Can you share the .img with me? I have TWRP installed with locked bootloader
I've found older stock recovery on this site : https://mega.nz/#F!lodnzDhK!H5ChxausDTyko1qGlnF7dw!Fg9FwLoa
Credit to ThanveerAliSayed in XDA
Well it seem that I cannot downgrade, the latest recovery don't want to install a lower version and when I try to get a older stock recovery I still cannot downgrade since it get stuck at verifying image update package.
Also I've noticed that my version is 21.40.1220.1698 and so far I can't find anything related to this version for rooting or unlocking bootloader. Even the official firmware on asus website for the ZE551KL is older than this version and I couldn't flash it. I had to get it from https://asus.kremowka.xyz/categories/show/2 because I've soft bricked my device. I'm still trying to find a solution...

I would NOT use this stock image for ze551kl. There is one for the 601 and the 550 but not 551kl. I will find the thread with the first stock recovery posted that I used and post the link in a while. Give me a chance to find it. I would roll back to it, then upgrade to the stock firmware listed in the unlocker notes. Once it's unlocked, you can go to the last lollipop before marshmallow and flash it. I would then factory reset, then flash marshmallow. After you have it working, then flash twrp (or just boot it in adb) as I said above and flash supersu.
I will warn you that a lot of people have had trouble unlocking and this might not work to unlock.

http://forum.xda-developers.com/attachment.php?attachmentid=3585486&d=1450811354 here is the link to stock for the very first stock firmware. I followed a video posted on YouTube from "themobileshots" on returning to stock from cm13. I doubt you can flash the stock recovery without flashing twrp first, then flashing from there. There are a lot of people in this forum that can help and most are pretty patient. Don't give up.
Finally I got my phone unlocked and rooted and it was too easy ...
I used fastboot to flash TWRP ( http://forum.xda-developers.com/zen...e601kl-official-marshmallow-wwv21-40-t3424903 ) and after that I flashed the latest CM13 from TWRP to gain root and unlocked my bootloader with this guide http://forum.xda-developers.com/zen...de-unlock-bootloader-asus-unlock-app-t3405850
I never though I could flash TWRP with a locked bootloader but it worked very well.

I tried to do a lot of things to get back to Stock ROM but they didn't work. I watched that tutorial but the files belongs to ZE550kl, so any other ideas? :crying:

Me too the first time I tried to unlock my bootloader in CM13 it didn't worked. I followed the guide and I did this :
Phone connected to the computer with USB debug and using ADB :
Code:
adb shell
su
Then I followed the backup procedure and I did the magic command to unlock it :
Code:
echo -ne "\x01" | dd obs=1 count=1 seek=16 of=/dev/block/bootdevice/by-name/devinfo
After I rebooted in fastboot so see if my device was unlocked but no it was still lock. I did two adb reboot with these command :
Code:
fastboot oem adb_enable
fastboot oem adb_enable
You have to do these twice.
After this my bootloader was still locked but I did a normal reboot and tried the magic command and voila! Bootloader unlocked.

If you have the ZE551KL like me you have to use file for a Z00T. You can check this page to know which device is a Z00T : http://forum.xda-developers.com/zenfone-2-laser/general/index-zenfone-2-laser-variants-t3369569
In my case I also had some difficulty to go back to Stock since I couldn't find the right firmware for mine because my android version is 21.40.1220.1698 and you have to flash the same version. The only place I found it was there https://asus.kremowka.xyz/categories/show/2 under the ZE601KL

The video is for the 550 but the process is the same for the 551kl (zootd). I downloaded the stock firmware at the bottom of the page on the Asus support page https://www.asus.com/support/Download/39/1/0/23/SZCx58yhB5Jst0yI/32/ , extracted it, grabbed the boot.IMG from there and put it on my memory card along with the stock recovery from the link above (renamed it recovery.img) and the full firmware (drag the original, leave it zipped). Then I did as the video says and wiped in twrp, flashed the boot and recovery, wiped cache, then flashed the firmware. It took awhile for the process to complete. Hope this helps.

For the stock MM yep I did it. I just installed the stock one after my bootloader was unlock and followed a tutorial here for root. I really like the stock Asus, way better than the samsung with touchwiz in my opinion.

So, to recap. If you are at the latest update, and have never previously unlocked bootloader or rooted your phone. The ASUS provided unlock tool won't work on the latest update. With it locked you can't install custom recovery or downgrade the firmware to an older version so that you can unlock it. Catch 22. Screwed until ASUS releases an update to their unlock tool or someone figures something else out. Or am I missing something? Cause I've been trying to do something with my kids phone for two days now and no luck here doing anything. Bout 8 million guides and files around the net and none of em seem to do squat in my situation. Any comments? Let's hear em.

Trying to reset my phone to factory stock

Had some issues with my camera recently and decided to do a nandroid restore. Restore didn't turn out well and I ended up with a factory reset device and here's where things get confusing for me.
1. I'm using the A2017G with B03.
2. TWRP installed and phone rooted, but bootloader LOCKED. Previously followed tenfar's guide back in August 2016.
3. Now my phone still has TWRP installed but no longer has root access. I wish to revert everything back to stock (i.e. stock recovery, everything) and do the proper method according to this guide but I do not know where to start as I don't even know the current state of my phone due to the locked bootloader. I fear that if I proceed with Controllerboy's consolidated guide, I may just brick my phone.
Appreciate any help rendered!

You can use the MiFlash file to unlock the bootloader just like Controllerboy says in his guide. You don't need to do the TWRP part since you already have it xd
There shouldn't be any trouble since, if you read his guide, you flash TWRP before unlocking the bootloader.
Edit: sorry he doesn't use MiFlash xd. Should still be the same, just use those images he provides to unlock it.
Otherwise you should be able to use MiFlash with some files that the Russians made, there's one called A2017U_FASTBOOT_UNLOCK_EDL which besides from probably unlocking your device, gives you Fastboot if you are on A2017G.

Hey guys,

plz give me a hint or throw a link in at me, If i´m missing something obvious :silly:
Can't you just install the official LG suite software on a desktop or laptop and then use that? It will probably detect the missing or "damaged" recovery and then automatically "repair".

Now I'm on stock rom with stock recovery, but the "fastboot oem lock" leads to a "corrupt device" that will not boot anymore. Can't the H870 (europe) be relocked, once it was unlocked via unlock.bin?
Isn't that the exact same procedure but then simply choosing "lock"?

Is there a "lock.bin" file that can be fetched from the LG site maybe?
From the LG developer site:
4. Once unlocked, it cannot be undone.
There is no turning back once you have unlocked the bootloader. You will not be able to revert your phone to locked status.

Returning to Stock

I just got this phone and I'm debating on unlocking the bootloader and rooting it and I was just curious if in the future I need to return it to stock (especially for selling it in the future) how do you go about doing that? Do you just flash one of the stock firmwares though TWRP like I found here? http://downloads.codefi.re/autoprime/LG/LG_G6/US997/US997-USA/US99714a
Then what do you do if that is correct? Also how do you relock the bootloader? I'm sorry if these are noob questions but I have been out of the modding game for a good while.

Just flash a kdz trough LGup and the phone will be completely stock, no twrp and no root. Then you have to only lock the bootloader by typing "fastboot oem lock". Don't run this command while you have twrp and root!
Ah, and the fact you have relocked the bootloader doesn't mean that you recovered the manufacturer warranty, LG can easily verify if you used the unlock bin.

I did some searching and found this. Is it the correct thing? http://rootmygalaxy.net/download-latest-lgup-tool-for-lg-devices-flash-tool/
Also just to be clear I unlock my bootloader, install TWRP and root the phone. If I ever want to go back to stock for selling the phone or whatever I just download the latest KDZ file like I linked to above and then I flash it to the phone and it will return everything back to stock? Then after that you just do the relock command and the bootloader is closed again?
I appreciate your help. I just to be super clear.

Ok then
LGUP
Hi, so I started flashing the kdz on my LG G6 using LGUP and it starts, but then randomly quits out. It's recognising my device and the file is definitely the correct one. Any hints as to why it's not working?
EDIT: I managed to fix it, apparently Windows Defender was seeing Uppercut as a virus and stopping it from creating the files it needed to. So make sure you turn off Windows Defender when you do this.
My experience with returning phone to stock is bad. First unlocked bootloader, installed twrp, bootloader for havoc ROM and ROM itself..
Havoc 3.1 OK, but BT calling not working, so I decide go back to stock.
LGUP used without problem, but then camera neither flash ligh doesnt work anymore.
Last firmware for H870 used from official.
Have someone same shi t experience like me?
Trying everything, but no success.
So its not easy go back to stock again..
(My phone is H870 for EU)

It's a known problem, the A10 ROMs somehow mess with files needed for stock camera that aren't included in stock pie.
You have to flash Oreo bootloader and then 30b zip for the camera to work.
If that doesn't work flash Oreo kdz and update to Pie.

Problem finally solved!
Tried many times flash Oreo bootloader and then 30b(pie), 20a (oreo). With 30b everythings work except camera. With oreo 20a phone wasnt even bootup normally.. (after reset just screen with green android and message "No commands" appear. I used LG UP 1.14 with Uppercut.
Then after many unsuccesses I put phone to state where bootloop appeared and I thought about to throw it into garbage.
ADB shell and TWRP saved me... I was again able flash roms.
At the end I found some package with LG UP 1.14 and patch (so I could use it without Uppercut...there is a new LGUP_common DLL), and with this combination flash procedure worked smoothly.
BUT! I had to load nougat stock rom first (H87011i_00_OPEN_EU_OP_0108.kdz), which fix partitions in phone somehow (but there wasnt possibility upgrade higher). Everything, camera included was working with this rom..
Then I flash oreo stock rom (H87020a_00_OPEN_EU_OP_0423.kdz), and now It booted right (no "no command" during startup). Phone worked perfectly, and I used OTA upgrade to land on 30b pie last official update.. tadaaa
Hope it will help others with same problem..
