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

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.

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.

Yes I'm currently writing one
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.

This METHOD was developed ONLY for an UNLOCKED Motorola Droid Razr Maxx HD XT926m phone that is already updated to the last version of KitKat 4.4.2 (System version "183.46.15.XT926.Verizon.en.US").
IF YOU HAVE AN LOCKED BOOTLOADER AND TRY THIS METHOD IT WILL BE ONLY YOUR RESPONSABILITY IF YOU DAMAGE YOUR PHONE !!!
My Motorola XT926m had an UNLOCKED BOOTLOADER (ICS 4.0.4) and I flashed via RSD Lite the last stock firmware, "183.46.15"... After that, I was, of course, unhappy, because I read on different forums that this firmware version didn't support root... I tried to download the Hydrogen Peroxide xt926 application that others users recommended here on XDA forum, without success.
But now, after I applied this method, my phone is again rooted... Enjoy the steps, but be carefull, it was developed for XT926 phones with UNLOCKED BOOTLOADER!
1. Download the files "VZW_XT926_4.4.2-KDA20.62-10.1_CFC_1FF.xml" and "VZW_XT926_4.4.2-KDA20.62-15.1_CFC_1FF.xml" from the Motorola firmware site: "motofirmware.com/files/file/"...
2. Unpack the files...
3. Substitute/replace the "gpt", "tz" files (FROM the folder with "15.1" version TO the folder with "10.1" version)... You should replace all the files that "RSD Lite" will tell you that don't fit when you try to flash the new stock firmware. You will obtain a MODIFIED version of "183.46.10" stock KitKAt 4.4.2 firmware!!!
4. Flash this MODIFIED "10.1" firmware with "RSD Lite v6.1.5 Multi-Flash" (without using Rsd Script Generator.jar), but don't forget to remove the first two 'getvar' lines in the xml file.
5. Download and install the "Towel Root.apk" and root the phone...
6. Now your phone should be ROOTED.
What to do NEXT:
7.Download from the Play Store and install "Superuser.apk" made by ClockWordMode and after reboot the application will ask you to update SU binary. In my case, the SU binary didn't support an online update and I installed the "Superuser.zip" file downloaded from the ClockWorkMode site, via recovery method, in order to gain this update (you can do this as well, if you already have a TWRP or CWM recovery installed on your phone). With the other version of superuser, like "SuperSU.apk" or "Superuser.apk" ("eu.chainfire.supersu-2.apk", the last version, 5.6mb, for example) you will need to follow the same steps...
8. Using "Total Commander.apk", you can go to "File System root"/"Etc"/"installrecovery.sh", and finally rename this last file... Or you can use "ES3 File Explorer.apk" in order to rename the same "installrecovery.sh" file in "Device"/"Etc" folder (choose, for example, the name "installrecovery.shbak")...
9. Flash with "Flashify.apk" (downloaded form PLay Store) a new "recovery img.": "TWRP.img" (2.8.3.0) or "CWM.img" (6.0.4.8) for KitKat... You can find them on "rootjunkysdl.com/?device=Droid%20Razr%20HD&folder=Firmware"...
10. If you flashed "TWPR recovery.img" you will need to install "Stericson.busybox-1.apk" (from Play Store...), because TWRP works with this busy box... (You could install "TWRP.apk" as well, but you must be careful, because you will need to be able to boot into Recovery mode directly from your phone (with the combination key), not from this app... Many times, the phone is able to boot into recovery mode from TWRP application, but not from the bootloader... That's why it is better to uninstall TWRP application if you have this problem). If you flashed a "CWM.img" you can install "RomManager.apk".
11.Now it is the time to backup your system to SD card!
That's it. My phone was unlocked, and I didn't have any issue following all this steps... If you're locked don't try it.
But.. If you're locked you could instead use an application named 'Safestrap' for some purposes (read more here on XDA forum please), because is destinated for the phones with locked bootloader...

THANKS!
I know you took a lot of time to write this up, but there is a downgrade method posted on here already. Also, there is no need to rename recovery.sh. All you need to do after flashing recovery is power off the phone and immediately boot straight back into recovery so the install script completes.
To answer your question, no, you can't unlock .15.

Yeah, unfortunately this post makes no sense, I mean, if you accidently flash the gpt.bin, you're screwed... and so many risks, plus, you can't flash custom recovery, and you can maybe downgrade the system and boot, but you still can't downgrade the bootloader...

This method is for an XT926 with UNLOCKED BOOTLOADER, with the last 183.46.15 update and the root access lost. I only described the steps that I already done with my phone. My Maxx HD is working and has root access again... I flashed custom recovery too (TWRP 2.8.3.0), I haven't any other problem.

The piece you are referring to that doesn't work on .15 is the unlock and root. The downgrade should work on an unlocked phone.
That aside, your steps are very confusing and could easily cause a locked user to brick their phone. Please clarify or I will continue reporting this thread until it gets removed.

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.

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:

I did, got no problems so far. But you will lose all data when unlocking the bootloader, if its already unlocked then rooting isn't going to wipe your data. I also installed xposed and got no problems with it

Looks like your trying to downgrade firmware there and from what I'm aware you can't downgrade certain sections like bootloader etc. What is it you're trying to achieve?

I was just trying to flash the stock rom. Had some glitches in my phone. While I was trying to flash via adb, couple of steps failed and then I was not able to boot my phone back.
Im sure that I'm using the latest version of ROM. However, it's the one before the latest security patch. However, the boot image and recovery image should remain the same.
Here's the version that I'm trying to flash.
XT1641-XT1643_6.0.1_MPJ24.139-13.1_cid50_subsidy-DEFAULT_CFC
No matter what I do now, I just cannot get my phone to boot in recovery mode or just boot normally.

Please read the post carefully before typing in any stupid commands that can screw up your phone.
Follow instructions EXACTLY as mentioned in this post.
The reason you are getting a “security downgrade” error is because you are trying to downgrade your bootloader, or GPT partitions. You cannot do that on the device.

Didn't you make backup...? First thing one should do is it....
You cannot flash official zip either soak or final by TWRP, you need stock recoveryfor that...
Now you can only do is flash stock via fastboot method (but you updated to soak it is not preferable)
Try this:
download any custom ROM from development, and load it to memory card, and flash it....

Since you haven't made backup, you have to go with fastboot flashing... As you updated soak your bootloader is now updated with it, don't downgrade it.... You will see gpt and downgrade errors while flashing... I can't say anything more about it, i didn't try that.....
You can follow guides available, see in guide section...

So if I want to fix my phone I need to wait for the official system images for Nougat? Since my bootloader is locked

I'm thinking same, That will be better..
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.

Pretty much yes, search for uppercut if you have driver problems with LGup, and for firmwares this is the best site to download them: https://lg-firmwares.com/lg-h870-firmwares/

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..
