Unlock bootloader without any bugs [Official method by ASUS] - Zenfone 5 General

Hi there,
I want to share with you a bootloader unlock method that worked perfectly for me.
STEPS:
Download official stock kitkat rom: ROM
Extract boot, fastboot and recovery from it and flash them from fastboot then flash the rom
Download official Asus tool for unlocking bootloader: TOOL
Install it and follow the procedure
If all goes fine when you switch on the phone the background behind the Asus logo is white instead of black.
It's easy and maybe a "stupid" method but it worked on my Zenfone 5 T00J.
The firmware listed in this topic is the only for me that allowed to use correctly the unlocking bl app.
If there are problems, I'm available :good:

do you have unlocker tool for zenfone 6 ?

My bootloader is alwery unlocked, but with black background, now I unlocked with this and its white, great , I was tired of that bootlogo

Works the same as all other methods, doesn't fix "freeze" or "no camera" issue...

Ghi98 I m also using tooj 8gb 1.2ghz. Facing bootlap are u also using this version

Followed instruction carefully, all seem be right: black logo, white ground. But can not flash TWRP, how can flash cooked ROM?

How many days have you used it after unlock bootloader? Try to flash some Roms yet?
And if your Zen still freeze even once... then delete this thread please.
Goodluck.

IMHO...
Based stock customrom can be relocked bootloader to avoid freezing matter.
Would you mind to try cm based or aosp based custom rom?
RR or xosp maybe?

[Q] Fastboot / unlocking bootloader

Hey Guys,
quick question - where is the bootloader on this thing?
I just received my G Pad today - used towelroot and flashify to flash twrp and was able to get root and do a nandroid in twrp.
BUT:
while booting recovery via adb command (and via quick boot) it identifies as V510 and states boot success bootloader unlocked.
Yet i can't boot to recovery or bootloader via vol up/down and no bootloader via ad reboot bootloader or quick boot/termnial
where can i unlock that bootloader for sure? all i could find was the normal fastboot method with oem unlock but no fastboot for me.
Any help/hint is appreciated.
Cheers
Buster
PS: (edit)
I don't mean download mode - this works (LG Tool recognizes it)
Have a look over here: https://www.youtube.com/watch?v=uo3YfszOPsQ
or
On the tablet start Flashify , in the menu press: reboot to recovery.

Are you sure it's a V510 (Google Play Edition)? What was the stock ROM? GPE or LGs ROM?

What I suspected. Sounds like the incorrect version of TWRP was installed. You'll need to go the the V500 thread, pinned to the top of the General section and follow the various instructions for installing Loki. You can't unlock your bootloader on the V500, per se. There is a work around. That's why you couldn't find what you were looking for.

Well that explains it then - if only the GPE edition is unlockable - it goes back to the seller. and LG gets a nice email about that.
also since I'm on 4.4.2 now the loki install fails so I'm out of luck anyways. (TWRP was the correct one btw on 4.2.2.)
thanks

dont know! just try it out!
i think the freeze issue is due to the kernel and not the bootloader . because people are facing the freeze issue still after when the bootloader is unlocked.
and i also had freeze issues in the past in RR ROM but it was due to kernel!.(knone kernel) .

Man I too have the same problem... damm thing starts to freeze whenever i try to unlock bootloader...whatever hopes i had from this phone were diminished when i found that it freezes upon unlocking bootloader.. I can't do 90 % of the stuff i want without a custom recovery...... There is not much diff between an Android and Windows phone if the bootloader cannot be unlocked without freezes... I wish someone figure out a way to deal with it ..

If you guys are on stock rom then
try flashing the latest BORETS24 custom kernel and also push the if.bin file provided by him to system/etc/firmware location.
and check if it fixes the freeze issue!

After I used it with Lollipop droidboot ww t00j stock .78 I had problems with camera. It works only with kitkat?
@ XHook
have you worked on method to re-lock bootloader..
bricked my bootloader
After flashing this I couldn't access my fastboot. Now I can't even boot to system. I'm stuck at the USB logo, where usually I could reboot to fastboot (via pressing Power & Vol +) to fix this. But now I can't even access fastboot. When I press Power & Volume Up, it shows a battery icon. Please do help @XHook.
Editted:
Sorry for panicking back there. I forgot the reboot to recovery way using Power & Volume down. At least I can still boot to my system. I'll try to find a DIY solution for this. Sorry for panicking, @XHook.
Your tool uses Fastboot of 4.3 version right? Is that the difference?
no more update? camera not found, can this method by xhook solve the problem?
i've tried this version, but make my bootloader missing/bricked, same with ezrawk post
Note : When I installed this version >> 3.24.40.87 latest stock lollipop firmware
@XHook, tell me what your firmware version when you install this UBL method.
Thanks

I was using a custom recovery (TWRP) at that time so I flashed a fastboot via install. If you aren't using a custom recovery, you'd probably want to check this out: Zenfone 5 A500CG, Zenfone 6 A600CG Last chance to debrick (This fix youre IMEI) by swiczak
About the flashable fastboot, try searching for it in the Help & Troubleshooting part, I think the user who upload the flashable fastboot zip was tank0412. Try PM-ing him. Sorry can't help you about this 'cause I forgot where I saved mine.
Goodluck!

re locking bootloader is possible. flash raw firmware. or flashing boot, recovery, fastboot and ifwi images.
@DarkshadoW99 very first of all you started new thread without searching around. and if you started a new thread your post is too confusing or lacking the context of your post. unable to understand what you actually want.
very first of all while unlocking bootloader with unofficial method. you may get error " failed too many links" but even though bootloader is unlocked pretty well.. ( mention which tool you are using to unlock bootloader)
second thing is you stated that you are trying to unlock bootloader to access recovery. what does it actually mean? do you want to flash custom recovery or your are unable to enter recovery mode?
"in marshmallow if you boot with unlocked bootloader the phone stuck on asus logo" what does this line means? are you stuck at asus logo? as far as i know you can boot in MM with unlocked bootloader too. unable to understand what you wanted to say.
Go back to Lollipop for bootloader unlock

Since there isn't any OFFICIAL unlocker for Zenfone 2 Marshamallow, your best bet is to go back to Lollipop abd having an unlocked bootloader but again, it'll be without Marshmallow:
Download official firmware latest release or whatever you had BEFORE installing LineageOS. Rename the the file you just downloaded to:
MOFD_SDUPDATE.zip
Click to expand...
Click to collapse
and put it on an SD-Card, put the sd card in your phone, boot into recovery (by booting to fastboot and selecting recovery) and the restore should start automatically.
Now at this point you'd be back to stock marshmallow and you can downgrade back to Lollipop ( V52.20.40.197--be mindful the link is for the JP SKU and you need to download the right SKU version for your phone in case you have WW --didnt see you specify or not, so maybe you want to check you downloaded the right Lineage OS as well as maybe thas why its freezing ) to use Asus' Unlocker.apk [You can find instructions on official Asus website under support]

If the last thing he installed was LinOS then he has twrp for recovery. I don't think that method will work.

That's a very valid point, but since his post is vague and quite confusing, unless Lineage has a function within the ROM to "relock the bootloader" I would've assumed he "relocked the bootloader" by installing/fastboot flashing some official boot.img and since he cant get into recovery and his bootloader is locked, I had imagined he'd be back to stock fastboot.
but meh, my guess is as good as any. Unless the OP adds some clarity, we can at least say we tried, amirite?

If the last thing he installed was LinOS then he has twrp for recovery. I don't think that method will work.

If you can unlock the bootloader again, I'd guess the flash didn't manage to erase everything.
Normally you'd have to boot and enable OEM unlocking before being able to unlock bootloader.

Did gsi android 10 flash recently?
if the answer is yes
with the bootloader unlocked you must boot twrp and flash stock-repartition.zip
You can now block the bootloader in stock without bootloop

There is another way too. Put your phone in EDL mode (fastboot oem edl) and flash the stock rom again. Even with clear_all_lock option enabled ,your phone won't lock your bootloader. When the phone boots up after flash,and you see the boot screen wait until you see erasing circle,after the second reboot,hold VOL - and power button until you go in fastboot mode. Then on your PC type: fastboot oem lock. The phone will boot up,then it will erase user data ,and you are ready with locked bootloader. I didn't have the stock repartition script ,so that's what i did.

If it works unlocked but not locked, something is modified. Leave it unlocked or flash a complete stock rom.

Probably something failed to flash. I don't know how much error checking the script has. Try again? Take note of the output, looking for warnings and errors.
