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.

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.

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.

Trying to allow my OTA update to shine through but it freaks out while rebooting into TWRP. I found this stock recovery: recovery_verified.img__Europe_1.61.401.6. Will this work on a US M9+?
I already unrooted and am trying to restore back to factory as much as possible since I'm getting the OTA update nags.
Thanks!!
you should flash last stock recovery that match to your current software number....
after flash recovery relock bootloader and use (htc_fastboot.exe) to flash RUU

Here is my story,
I recently updated my moto g4 plus XT1643 Indian version to android 7. Then i tried to root with some guide from google, it softbricked my device. Fortunately i had a MM nandroid backup, i backed up and everything is alright.
I tried to upgrade to android N again, but i got an error "Bootloader preflash error" and "Remote failure" during same course of locking my bootloader and setting up system as default. Please help, how can i upgrade again to android 7?

Reinstall the original stock rom for your device again, not with a TWRP nandroid backup, but, using fastboot! After that, preform a regular OTA update, just to be sure you're on the latest Marshmallow.
Then flash the Nougat update using STOCK recovery!
If you want to root again, follow this guide carefully!

Hi, i tried this method and upgraded to Nougat successfully, later i tried to root and soft bricked the device and recovered MarshMallow from TWRP. Now, this upgrade method is not working, that's the problem.

Not able to flash anything with fastboot, "Bootloader downgrade error"
Got everything normal,
Flashed boot and system files, omitted bootloader, gpt.bin and recovery. Later flashed recovery and android N update, everything okay now, thanks everyone.
Once upgraded, the N Bootloader cannot be downgraded to MM, it was somewhere in those threads.

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...

We don't have it for any variant... Don't know if we ever will, never been leaked and the sources for them are questionable if we will ever get any more factory images at all.
What is the problem?

Why do you want relock BL? It can help with... nothing.
You can flash the newest version RetEu 6.0.1 with oem_lock commands.
I suggest rather:
Flash the first 6.0.1 reteu 24...58 without locking
If everything will be ok:
Flash the last 6.0.1 24...58-5 with locking BL.
After it you should get one or two OTAs.
Remember: bootloop with locked BL - only authorized service can help.

Oh, probably wont do that then.
Another question, can i download the android 7 ota uodate when i get it still? With an unlocked bootloader saying "Offical" and twrp?
So far ota update is only for 24...58-13.
With twrp you can't install any ota update.
Unlocked BL doesn't matter for OTAs.

Exactly, i need to get rid off twrp, but i can only do that if i flash a stock recovery, which i cant
It might be worth trying this older firmware whose name suggests that it is reteu for UK and FR, and seeing if newer OTAs show up:
https://firmware.center/firmware/Mo..._MPH24.49-18_cid7_subsidy-DEFAULT_CFC.xml.zip
More available here, but none of them seem like they're for UK phones:

If your bootloader is unlocked and you're trying to lock it, you could try flashing it while keeping the bootloader unlocked, and then flash it again as part of the flashboot oem lock begin -> flashboot oem lock process. (From what I've seen, the device is fine flashing older firmware with an unlocked bootloader, but not with a locked one.)
