Looks like it'll surely help in unlocking and relocking my bootloader if I want to claim my warranty anyway ?

Thanks in advance ZE550KL.

MM 6.0.1 ?

hello,

first by your rooting, did your phone was on MM 6.0.1 ?
[Zenfone 2 Laser General] bdwilk:
I was on the latest lollipop firmware 1.17.40.1531 and then rooted using the latest pre-rooted MM firmware. After unlocking your bootloader the easiest method for TWRP is to download the latest TWRP on your phone and flash it through flashify.
[Zenfone 2 Laser General] cappoccia:
So you can't confirm that it will work on MM 6.0.1?
[Zenfone 2 Laser General] bdwilk:
Root? All your doing is injecting a rooted system image into your own. If it will work putting MM into LP then it'll work putting MM into MM. But no, I cannot confirm through experience. This is the bootloader unlocking thread by the way.

---------- Post added at 12:51 AM ---------- Previous post was at 12:27 AM ----------

I guess I don't understand your question. I can confirm that unlocking the bootloader works from MM. I was on pre-rooted MM firmware.

[Zenfone 2 Laser General] cappoccia:
Sorry

I'm sorry, you're right. This is the bootloader unlocking thread.

I think I asked a question in the wrong thread.

my intention, for now, is rooting my phone without changing OS (that is the stock MM 6.0.1)

then after I consider unlocking the bootloader when I want to flash a custom ROM.

If you have any suggestions I accept it happily

thank you

This is the thread you want. You can choose in the download section which firmware you want to be rooted on. LP or MM. It's the method I used and if you follow directions then it's pretty simple. Hit the thanks button if I helped. Good luck.
[Zenfone 2 Laser General] cappoccia:
I've seen this post. my intention for now is to not touch the original os

the [MENTION=1813976]shakalaca[/MENTION] procedure assumes that you still need to flash a modified rom (thing that I don't want to do)

for the moment I want only to root my phone.
[Zenfone 2 Laser General] bdwilk:
It just replaces your stock system image with a rooted stock image. It's still the exact same stock rom.....just rooted.
[Zenfone 2 Laser General] cappoccia:
thanks

wow! how fast are you posting....what time is it in the philippines?

but these stock rooted images are certified?

in the sense they are fully identical to the original ones (with all the asus apps?) or are already some "custom ROMs"?

however already so you've been helping me, therefore I hitting for you the thanks button.:good:
[Zenfone 2 Laser General] bdwilk:
I tried to pm you to continue but it wouldn't let me. Anyways it is a fully stock rom just rooted. All the ASUS apps including bloatware. (it's 4pm btw)
[Zenfone 2 Laser General] urnamese3:
I think the command

fastboot oem adb_enable

needs to be done before the

echo -ne "\x01" | dd obs=1 count=1 seek=16 of=/dev/block/bootdevice/by-name/devinfo

command, or am I wrong?
[Zenfone 2 Laser General] bdwilk:
I didn't have to use that command. I followed OP word for word and it worked flawlessly. Adb shell not emulator.
[Zenfone 2 Laser General] rldawesome:
Hello Everyone,

I am new here, so be patient with me :p

I'd like to know if I can do this on a ZD551KL, I have tried a lot of methods to unlock my bootloader but i have failed.

Sorry for my english, I hope you guys can understand me.
[Zenfone 2 Laser General] gustavohmsilva:
Hi; I kind of f#$ up everything and my phone is currently only loading fastboot and twrp...

Installing cyanogenmod by twrp get me stuck in "patching system image unconditionally"

Trying to install the stock ROM from fastboot gives me fail everytime (FAIL copying content).

So, given all that, I would like to recovery the phone to the previous point, using all the images from the "dumps-unlockedbl" folder. How can I do that? All the IMG files have the exact same name as their partitions? Or there's a special command to use on fastboot?

Thanks for your help guys!

You did it on emulator correct?

Try the unlocking using adb shell instead.
[Zenfone 2 Laser General] Harmton:
I used adb shell.

The problem is the block device (devinfo -> /dev/block/mmcblk0p15) is not changed a bit.
[Zenfone 2 Laser General] bdwilk:
What about trying on MM firmware?
[Zenfone 2 Laser General] Harmton:
Ok. Will try later and post result here.

For my phone this unlock method not work with v1531. Device mmcblk0p15 is not writable for root shell. Very strange. :confused:

What I've done for unlock: update to v1708 (MM) from sdcard, flash pre-rooted system.img by fastboot, wipe data, install supersu.

First attempt to unlock did not work. After reboot the second attempt was successful.

Can i relock the bootloader unlocked with the Asus unlock tool?

Please i really need to do it.
[Zenfone 2 Laser General] bdwilk:
]

There's a video on YouTube that says if you use the back2stock.zip from this forum (credits to [MENTION=5075128]LuK1337[/MENTION]) then it will lock your bootloader. Maybe for you who unlocked with the ASUS tool but I don't think it's that easy.

[youtube]Kh4z3mXtQxc[/youtube]
[Zenfone 2 Laser General] codejam100:
Video is misleading ! You can't relock your bootloader in ZF2 laser once it is unlocked.
[Zenfone 2 Laser General] bdwilk:
From what I've read and seen I totally agree with you. BUT, I am definitely not an expert. I have no experience with unlocking with the ASUS tool except I tried it and it didn't work. Therefore if the tool worked for someone else then I cannot say that there's no way to relock it. This guy says it's locked (I highly doubt it) then maybe try it and let everybody know through experience. I'm simply sharing what I saw.

Can anyone help me unlocking bootloader

Hey guys i am using a ZE550KL using sd615 and l'm on marshmallow. I've tried the asus unlocking app but failed as well as the post that claims can help reverting to lollipop but also failed .Can anyone give me clue on how to unlock bootloader ?
[Zenfone 2 Laser General] bdwilk:
Follow the OP of this thread. It works. I have the same model as you. I guarantee if you follow all steps correctly it'll work. You'll need to root first. There's a link in the OP.
[Zenfone 2 Laser General] leroycheng99:
But i haven't root yet and i dont have clue
[Zenfone 2 Laser General] bdwilk:
Read the original post. The entire post. Read it many times if you have to to understand. It will say you need root first then it provides a link to another thread that will tell you how to root. Do that first then come back here and reread the original post (OP)
[Zenfone 2 Laser General] leroycheng99:
Sorry and Thx i'll try
[Zenfone 2 Laser General] bdwilk:
Here use this thread for root. In the mega link for original firmware use the latest MM prerooted firmware. It starts with 21.

[MENTION=4544860]osm0sis[/MENTION] and [MENTION=6211994]sziraqui[/MENTION] permit me to bother you a little.

My device is MSM8916 variant, 2gb ram, running the latest Stock MM (rooted)

I noticed something with my radios. It has had issues with locking a LTE signal on both sims ever since I upgraded from Lollipop with the back2stock zip method.

It had the same behavior even on CM 13 and 14.

Recently i decided to flash that baseband/modem file being shared to enable VOLTE and discovered that SIM2 now locks LTE signals just fine but SIM1 retains the problem.

This made me realize that the issue must have to do with some changes I made

NB: both sim slots worked fine with LTE when I was on lollipop build.

I have a backup of my partitions before unlocking.

Do you have any ideas on what may be wrong and how to solve it?
[Zenfone 2 Laser General] abhinavze550kl:

Go back and follow the directions. It works. Remember to copy/paste the commands and use adb shell instead of an emulator. It's just easier that way.

Well to unlock the bootloader with this method first requires root access. In which case if you followed the steps it would require flashing a prerooted system.img which already has SuperSU installed. Hence root access. Does that help?

[Android Q&A, Help & Troubleshooting] ItinerAecus:
Hi, I'm using a non-rooted stock Moto G3 that I had set up to use an SD card as adoptable storage. Yesterday I started getting notifications to insert the linked SD card even though it had never been removed. Upon removing it and reinserting it, there was a long "checking" process that I noticed in the storage settings page which eventually ended with the status "corrputed". If I take the SD card out and look at the partitions in GParted, I see two android partitions of the correct size. It looks like the data is still here, however, I cannot mount it due to the encryption. I found a guide on how to get the encryption key from the /data/misc/vold file, but since the phone is not rooted permission is denied. Are there any methods I can use to get to the encryption key or some other method to recover the data?

Thank you very much!
[Android Q&A, Help & Troubleshooting] zelendel:
You are out of luck. You are gonna have to wipe the sdcard. This is why most oem removed the option.

My only advise is that if you are gonna use the sdcard then remove the encryption or just don't use if for anything other then storage.
[Android Q&A, Help & Troubleshooting] ItinerAecus:
Well, I did have some luck. Since I was still able to see the partitions, I was able to clone the data to a new SD card which was recognized by Android. I have not noticed any missing data yet. The old SD card is now stuck as read-only, so I cannot delete the partitions and reformat. I will be sending it back since it is still under warranty. Thanks for the advice. I will definitely move away from the adoptable storage method.
[Android Q&A, Help & Troubleshooting] iXaidyiu:
You mean the adopted SD card can still be protected by warranty?
