How to unlock Bootloader. Currently running 2.20.40.183 ZE551ML - ZenFone 2 Q&A, Help & Troubleshooting

I've tried several threads here and none is working.
I did all the downgrade, still not working.
Please help.

Try running the unofficial bootloader unlock tool... I used it on 174 update with no problems... Just remember to have developer settings active and USB debugging ticked...
Remember, unless you like the white ASUS start screen you'll need to flash the normal black bootscreen again using fastboot...

The official Asus bootloader unlock tool is also handy and I think works for newer versions, though if your phone is still under warranty, you can't hide that you've unlocked your bootloader using the official one because it contacts Asus's servers, unlike if you use the unoffical one, you may still be able to keep your warranty, but that's not guarantee. You can always flash the stock black splash screen to hide it in case you need to return your phone for repair.
You can download the official unlock tool here

I just tried to unlock the bootloader and it said "unlock failed". I downloaded the tool from Asus website and made sure USB Debugging was on. I'm running 2.20. Is it possible to unlock the bootloader???
Thanks

[Q] Unlocking and Rooting a R800AT

I've been through a few guides and tips, yet I am still having trouble unlocking the bootloader and rooting an AT&T Xperia Play. I've tried using flashtools, downgrading firmwares, sonys official unlocking tool couldn't work, the manufacture date is past some programs limitations, and one last one suggested using gingerbreak and .184 UK firmware, however the .184 UK firmware is missing from links.
If anyone could help me out, or push me in the right direction, it would be greatly appriciated because I am completely lost.
I suppose to throw in some tests I did, after checking the rooting status using *#*#7378423#*#* on the dialer, nothing shows up indicating any rooting status, so the bootloader is still locked I suppose. The IMEI is 357593041206718, which is 15 characters and cannot be used for sony's official unlocking. The manufacture date is 12W15, past some companies ways to patch the boot loader, namely fastgsm's. I tried messaging the program from testpoint I guess (cannot post links but the second option to unlock in the wiki) to try and use their pay service.
A bit of progress, I believe I have unlocked and rooted the phone. When turned off, plugged in, and holding search, a blue light now appears. I ran super one click and got it to allow super user! Also, I got here by using an outside service to unlock my phone by shorting the two pins on the phone and plugging it in as well as using a credit.
So anyways, now even though WiFi is on and working, I cannot connect to the play store. Also confused at how to install a custom recovery software and how I can get my phone to ICS.

If your looking to install a custom recovery software download x-parts from the android store and it does recover root access however you can not install custom roms due to your locked bootloader. Yes you can install root or su on a locked bootloader. But to install a custom rom if that is what your going to do you need a unlock bootloader. In this case using a program called settool. Unlocking your bootloader is not free and I recommend alejandrissmo a reputable XDA member and he a site you can unlock your bootloader there.

Thank you for the reply, I have been able to unlock the bootloader through a difference source, same concept and did cost a tiny bit. Anyways now I'm lost trying to find a ROM that works, tried the AOKP customized release but wifi and bluetooth were not working. Have any suggestions?
Did you flash the wifi modules that went with the kernel you used? You could try to re-flash them if you did.

Yes, found that was the problem for most ROMs. AOKP still had the problem afterward though.
What kernel were you using with AOKP?

Official bootloader unlocking tool by asus!!!!

Asus has released official bootloader unlocking tool for our zenfone 2:laugh::laugh:
the have poted in there official myzen.asus.com
For some reason neither this nor the One-Click Unlocker is working for me. They reboot to bootloader, flash a few lines, and then cut to red text stating "Unlock fail - reboot in 5 seconds."
Does anyone have any idea what is happening or how I might fix it?
I have unlocked it using unofficial method. Any different to unlocking using official method, in terms of feature or functionality of the phone?
Yes. The difference is: official method doesn't work!
Nothing to see on this line
Be glad you didn't get the official tool to work because the official tool is causing bootloader-loop issues see this thread;

Accidentally locked bootloader

Alright guys, I was trying to fix my fingerprint (which I ended up doing) by flashing the global dev ROM 7.8.31 via fastboot with the miflash tool but I accidentally locked the bootloader while doing so. My phone came with the bootloader unlocked and now I can no longer unlock the bootloader. in developper options, the OEM unlocking option is enabled but no matter what I do in fastboot, the process simply does not work. I get the remote token verification has failed message. I have tried every freakin guide out there but my phone now refuses to get unlocked. I can't flash anything with miflash tool anymore, it just says failed, even when trying to flash the global dev 7.8.31 ROM. Anyone can help me here? Xiaomi says my device is unsupported for unlocking yet it was unlocked from the start........
What i did was the official unlock guide from xiaomi where you will get the code from them. Sadly you have to wait for 3days to be able to unlock them again.
Well check this thread...

You can reapply if you got rejected

Well I did that but it kept on saying I had too many IP requests of sorts but I used TunnelBear and set my location to Hong Kong and that allowed me to bypass that and the request was passed through. Surprisingly, I got a message 4 hours later that said I was able to unlock it instead of the 2-7 days it took for most people to get theirs
Same happened to me. I re-lock bootloader to install android pay, and bricked my phone.
Have to reboot in EDL mode (after >50 tries) and flash again.
But... Flashed a locked bootloader version, so i have to request for official unlock (phone came unlocked)
Now I have unlocked bootloader, with Magisk and Safety Net module with Android Pay working fine.
PS: i also had the IP problem. Used a Chinese proxy to override restriction.

Please HELP to unlock BootLoader - nothing works, looking for unofficial method

Hello there,
I've searched through all the googles and i can't seem to be able to unlock my mi 5S
Bought a half dead phone, glitchy screen and bad battery. Purchased new parts and had them installed.
Phone came with unlocked BL and lineage OS, but i f-ed it up by flashing a miui rom that locked the BL.
Then I found out the phone was actually bound to an existing MI account, so I cannot unlock it with the official tool.
Phone is in edl mode, i tried searching for an unlocked emmc_appsboot.mbn but no luck.
Can anyone please advise how to unofficialy unlock the bootloader?
I'm about to sell it for parts as I've been trying to fix it for the past week ... :crying:
Not sure if there is a way, because that way could also be used for a stolen device...
My suggestion is that you contact your seller and ask him for his Xiaomi account or that he deletes the phone from his account.
Weird thing though, the phone does not get locked if you just flash an official ROM. You specifically have to choose "flash + lock" in the official flashing application to have it locked again.

I've been emailing with xiaomi support, gave them all the details. Maybe I can convince them to remove the account.
Before flashing i was checking online on how to do it with miflash tool but i missed the radio buttons and default was clean and lock ..
After a few documents submitted through [email protected] they have removed the unknown mi account.
To conclude, I have not found any way of unlocking the bootloader except for the official way.
Also, be careful when flashing with miflash, don't lock your phone by mistake.
Ah great that it worked!

hi, take a look on this thread, there you will get detailed infos!
https://forum.xda-developers.com/on...store-to-complete-stock-relock-t3712739/page5
happy flashing
EASIEST way to relock BL and full stock firmware is using 9008 qualcomm unbrick tool to reprogramme it.
or fastboot method flashing stock firmware and relock BL manually.
