[ZE550ML/ZE551ML] Bootloader unlock and relock tool - ZenFone 2 General

All you need is rooted ZF2 with stock boot and firmware.
Just connect it with ADB Debug enabled and run *.bat.
Also accept adb debug root access on phone screen.
Initial release by drdaeman (source).
Slightly modifed by Yoti (it's me) (source).
Tested on my own ZE551ML. Not tested on any ZE550ML.
upd#[email protected]: some minor issue in relock.bat, plz use this instead of.
upd#[email protected]: updated tools with fixed typo

Thank you.

Is it really possible to relock bootloader ?? As anyone tested this yet ?

how we are gonna know that bootloader is relock.is there a way to be sure about that.

If you can't flash a thirdparty recovery (TWRP, CVM), then your bootloader must be locked.

but what if unlocked with other method? relock is possible with this method?

i am just trying this one if it is legit. 1st i intsall this tools. and twrp not working. now i try to adb sideload .174 firmware if i get update notifications then this is legit. now on adb sideload firmware waiting for the firmware to finish ill be back report here.

I was on CM 13, then i decided go back to stock. Flash drooidboot, recovery and boot and adb sideload .97 version.

Did you flash the raw too? Using flashtool? And did you unlock ur bootloader using official app unlock?
Click to expand...
Click to collapse
I didnt flash raw. I unlock the bootloader using the unoficial version (a long time ago).
This didnt work for me the first time because i didnt root first (after installing the full version .97). I just use the one click root then this and works for me (or at least i can do OTA again i guess bootloader its locked).

okie gonna go try .97 btw i unlock bootloader of mine from official unlock

Check your root, drivers etc. And you must reflash black splashscreen separatly. Probably, yes.

About reinstalled marshmallow rom help!

I had a custom rom trupure installed after rooting my phone unlocking boit loder and putting twpr,I wiped the rom and put back stock marshmallow. But left the phone with twrp and bootloader unlocked. Will I be able to receive OTA update w
With bootloader unlocked and twrp still installed? I heard there was 6.0.1 coming up already. Since I reinstalled the marshmallow stock back does it come with band 12 update already??
No with TWRP, you need to get stock recovery or just wait to somebody release the 6.0.1 rooted already.

OK how do I go back to stock recovery so I can receive the update? And what about the bootloader?
You can downgrade to LP using the tool that is on Devs section, then take to MM OTA again.

I also, humbly and respectfully, request that you do not blame the phone for your flashing problems. And I most humbly ask that you try to do additional reading and searching before you do anything else to your device. Almost all of your issues have been previously addressed in older posts and searching and reading are expectations for members. Hope the above link gets you there... :highfive:

[Guide] How to update to the Official MM safely from any rom.

Whether you come from Beta MM, LP or any other roms, if you want to update to update to the Official MM with no concern of bricking your phones, I advise you to flash the latest LP raw firmware (WW_ZE551ML_2.20.40.194_20160713.raw firmware), then ADB sideload the latest Official MM zip.

You go straight to MM from 194 version. But make sure you fully unroot before ugrading to MM if you currently have root. If not, just sideload the MM zip and do a factory reset when you're finished.

From fastboot, you have to flash the LP raw image which is in OP. Then, you can sideload the latest MM zip.

If you didn't save your unlock code, there is no option for you now to unlock it if your rom is not rooted and you have no custom recovery.
Wtf.
That is new for me...
No recovery?
My mod came with twrp!
What rom do you have before flashing?

After flashing your rom he flashed B896, which restores stock recovery and in his case - locked his bootloader (it didn't lock bootloader on my p8 lite though)

I think yes, because the bootloader not unlocked, and with stock firmware and wipe data the phone looks like new from store.

Root and broken

Hello my phone is broken, because I unlock the root, but his voice phone wifi is not working, so I am thinking whether my boot.img is wrong, if there is this version, can I share it. The version is SKYw1911010os00mp5 In addition, my English is not good. This is typed out using google translation. I'm very sorry.
I don't quite understand, tell me if this is correct.
1. You unlocked the bootloader
2. Then rooted your phone
3. After rooting, wifi doesn't work anymore
I'll assume, you rooted magisk since thats a common issue if the magisk version is not compatible you'll lose your wifi
If I'm correct, you flashed it via twrp. Where did you get it?
OR, you could have magisk patched your boot image using magisk manager and flashed it via fastboot
have you repair your phone ???
