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

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.

Anyway to root without unlocking BL?

I just got the Axon 7 and am loving it. Is there anyway to root the latest B29 software without unlocking the boot loader. I saw an older thread but the software was B27 and it seems out of date and people were complaining about the links being dead. Anyways thanks in advance!

So use the older b27 and root it that way? That shouldn't brick it should it? From the tool I understand it copy's your boot files so I guess that I could restore if need be?

You need to be on b27 to use that method. Just unlock bl if you want root.

Maybe a little too late for you, since I saw another of your threads saying you ended up restoring to B20
I was able to use TWRP and installed DrakenFX's BootStack and System images of B27 to downgrade from B29 to B27.
While I was trying to follow the "Root without unlocking bootloader" thread, I ran into some other issues though and my phone wouldn't boot so I tried a bunch of stuff and ended up re-flashing again to B27 and then restoring to B20.
But the good news was, after restoring to B20, I was able to follow the steps provided in http://forum.xda-developers.com/showpost.php?p=68302434&postcount=157 to root without unlocking. The last step not mentioned, is to install the superuser manager app mentioned in the first post of that thread, phh's superuser. I previously tried using Chainfire's SuperSu but it was missing some binaries and didn't seem to work.

Well crapola I ended up unlocking it
There's like alot of tools floating around with two different drivers so heck I ended up just combining a bunch of different methods lol. Needless to say I ended up unlocking the bootloader flashing TWRP and rooting. Thanks for coming in I might have to start over one day and that thread will help.

unable to update to 7.1.1

I've been trying to update to the 7.1.1 update, but i'm only being notified to install the nougat beta update.
I've cleared cache in apps>show system>system update and also in recovery as i've read in the axon forums.
I have the A2017U model. Build number is A2017UV1.0.0B29. Also, when i do try to update to the beta, im notified that the update package doesn't match the phone.
I'm kinda lost at this point. Can someone point me to the right direction?

Your phone has to be completely stock for the update to take. Bootloader unlocked, or fastboot are ok.
You can probably get away with flashing the B15 firmware via edl, then take the ota to b19. This should preserve your data. It is a good idea to back things up.
Your post lacks detail about what you've done to the phone to make it none stock as far as android OS goes.

Sorry, i bought the device from someone else about 2 months ago so i dont know whats been done. I know its not rooted nor does it have Twrp installed.
what the best way to flash stock?

Is the bootloader unlocked? Do you want to unlock it?
I'd say first unlock the bootloader then use the B15 edl method then let it upgrade to B19.

Want to relock bootloader

I tried to root H918 T-Mobile, and ended up with just an unlocked bootloader, and no TWRP install.
I'd like to re-lock the bootloader, but I can't find any instructions. Any unroot instructions I've seen, include using TWRP.
Thanks!

Same here, before i ended up bootloader unlocked. Well decided to relock the bootloader
Just fastboot oem locked

Try this method. As far as I know everything is back to stock at least it acts like it is.

Old thread but i found it while trying to restore my US996 back to factory. The kdz method works then you just run the fastboot command to relock the bootloader. Amazing it was that easy to relock the bootloader....

I flashed the 10s update to h918 and very stupidly forgot to flash root so I'm stuck on unrootable 10s. I want to lock my bootloader so can at least have Android Pay working, if i lock it can it be unlocked again or do i have to wait for a root method for the new 10s software?

I think you can unlock /relock as many times as you want. Root take place after unlocking but you can't do that anymore.

I rooted my v20 f800l a few months ago using dirty Santa method. Everything was going fine until I decided to reset my phone via twrp. I selected system, internal memory, cache and ended up without an os with only access to twrp. I had a nandroid backup but twrp couldnt read or detect the nandroid backup files. With nothing else left to do i flashed it with a kdz file version 10e using lgup software. Now I have my phone running fresh os very smoothly but the bootloader is locked and root/twrp is not there anymore. Now I plan on rooting it again as I'm still on 10e version but I'm not sure if there is a bootloader lock/relock limit, I've already unlocked bootloader once and locked it once, can I do it again? Or is there a limit to it? Please help

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.

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:

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.)
