[ZenFone 2 General] aethervagrant:
i thought i had unlocked the bootloader but i didnt get the splash screen and pushing twrp just broke my stock recovery. i had used the one click tool first, with this method in either adb shell or terminal emulator on the phone nothing happens. i have the latest firmware 19.4.2.2, do i need to fastboot push the old droidboot.img mentioned earlier?

i followed your instruction but no luck, when i use adb the phone reboot in "Normal Boot" in the bottom of the screen blue line says "Continue the fastboot process" and nothing happened, and when i use Terminal Emulator, when i type "getprop ro.isn > /factory/asuskey" and press enter it is shows permission denied even i granted the Terminal Emulator su permission.

[ZenFone 2 General] Akashami03:
Yeah, i also had a problem, my phone not unlock by both cmd and terminal emulator, i unlock by oneclick unlock tool. Try thats surely will work. link here. I rooted my device before unlock with that oneclick method, but that tool will work even in non-rooted devices. If you are in this version ( v2.19.40.18, v2.19.40.20, v2.19.40.22 ) use version 2 tool... i am in v2.19.40.22 when i unlock.

Is there a relock method yet? I just want to get my phone back to 100% stock. I have stock recovery and stock firmware and want to get rid of the white asus screen at boot
[ZenFone 2 General] fuzzybuffalo:
No way to relock yet, but you can flash the black splash screen from the first post.
[ZenFone 2 General] sportscrazed2:
Thanks my phone is weird it actually goes through the white screen and then the black screen before booting. Is this normal behavior? I don't particulararly care enough unless i have to send it in for warranty. But, it's safe to take any otas that come this way as long as it's not rooted?
[ZenFone 2 General] fuzzybuffalo:
Yes, that's normal. You get a white screen with black Asus after you unlock the bootloader, that's your splash screen.

Then you get the black screen with white Asus and it says Intel inside for a second then the dots circling, that's your boot animation.

Before you unlocked, you used to have a black splash screen. That's the file that's in the first post.

Yes, it's safe to take an OTA with an unlocked bootloader, makes no difference, I've done it 2 or 3 times already.

[TOOL] One-Click bootloader unlock (no root required)

Sent from my ASUS_Z00A
[ZenFone 2 General] mrcpu:
I am scratching my head. This process seems so trivial, but I cannot get it to work.

Su, getprop ro blahblah > /factory/asuskey, reboot bootloader, and I get the bootloader screen with "NORMAL BOOT" at top in green, and

a "fastboot waiting" in blue.

According to the original docs, it's supposed to restart itself, but it don't do jack until I tap the power button. NO white screen, no nothing.

What's weird though, is that it tells me the BOOTLOADER_VERSION is unknown on that bootloader screen, yet it will boot the rom fine. I'm on 2.19.40.22.

Under protest, I can do a factory restore, I hate to if there's an easier fix, but I will, I just need to know if that's my only real option.

[ZenFone 2 General] mrcpu:
Tried, but now my zenfone 2 isn't showing up in device manager at all. Tried 2 different PC's. Unchecking USB Debugging causes the phone to reboot. I can get in with ADB wireless, but that doesn't help me in download mode...

I wonder if I can reflash somehow a new droidboot.img or bootloader and see what's up.
[ZenFone 2 General] mrcpu:
Well, it's getting closer. Manually typed in the unlock commands from fastboot, which does find the phone, but adb over usb can't find it. adb over wireless works, so all is not yet lost. (btw, the last fastboot command stop_partitioning, has some errors, but finishes. The script redirects everything to nul, although I'm used to more unix-y /dev/null, so who knows, maybe a bunch of "nul" names files floating around on people's phones).

At least I have the white splash screen, and so I can monkey with other stuff.

Thanks for the help.

[ZenFone 2 General] idigg:
Could use some help. Just got my ze551ml and trying to get CM12.1 on it. I was able to install SuperSU on it. I then tried to unlock the bootloader with the "unlock_one_click_v2.bat". It failed and rebooted, but I didn't know it failed. I think it failed because the phone is on an older firmware, 2.18.40.12 to be exact. I flashed TWRP, it says it's successful, I try to boot into recovery but it just takes me back into fastboot mode. It's like my recovery is gone.

I'm not sure what to do at this point, I got a prompt to ugprade to 2.20.40.59, tried to install that, but my phone just boots into fastboot, making me again believe my recovery is gone. Any help? =\

Thanks
[ZenFone 2 General] OfficerJimLahey:
Yeah, your recovery is borked, probably because it is not signed in a way the locked bootloader expects.

Grab this file. It's not a perfect match (from 2.19.40.20), but it should work nonetheless.

Then, open a terminal in the same folder as the downbload, put your phone into fastboot mode, and issue the following command (by the way, at this point you should have adb and fastboot tools installed - if not, check this out):

fastboot flash recovery recovery-stock.img

Once complete, try to put your phone into recovery mode again. If good, reboot, and check for updates one more time. You should get the latest version now, to which you can try the 1-click BL unlock again.

Hope this helps.

Help Needed

Hey There, I need to give my phone for replacement but I had unlocked the bootloader. how do I Re lock it ???

I bought a Z00A online just a few days ago, rooted it, unlocked the bootloader, installed TWRP, and then CM12. All was perfect until I realized some hardware problems with the speaker. Also lately it doesn't boot up easily on pressing the power button. In fact every time I have to go to the bootloader and 'Normal Boot' from there. And even that doesn't happen all the time. I have installed the stock recovery, flashed back the black splashscreen, and also the stock-firmware through adb sideload successfully.

Now can someone tell me does flashing the stock firmware through adb sideload re-locks the bootloader or not ??

If no, what are my chances of getting a replacement ???
[ZenFone 2 General] 903tex:
You can't relock the bootloader chances are 50/50 on the repair.

What speaker problems are you having?
[ZenFone 2 General] Sumit Lakra:
During phone calls, nothing is audible in the Handheld mode. The Loudspeaker mode works fine though. Anyway, what good is a phone if you can't talk to someone on it....!!

Also it doesn't boot on holding down the power button. It does vibrate though for a short duration but doesn't boot up after that. Every time I have to press the volume up button along with the power button to enter the bootloader and then select the 'NORMAL BOOT' option to continue booting. Any idea how to solve this issue ??

I tried unlocking, but like a true idiot, I did not upgrade to 2.19.40.20 before attempting unlock.

Needless to say, the bootloader did not unlock.

Now, I'm not sure if it's related, however I cannot enter recovery mode. Every time I select Recovery from the Fastboot menu, the device reboots right back into Fastboot mode. I cannot get to the dead Android error screen to press Vol Up and Power, so I cannot flash the upgrade.

[ZenFone 2 General] nasir150:
I also tried, but can't install while I'm at 2.20.40.90. Also my stock recovery was gone as I'm tried to unlock bootloader (and i though it's unlocked), but actually not unlocked. And in this stage I tried to install custom twrm (unteather) with all method. So, my stock recovery gone, as well custom recovery also not installed (If I select recovery, it always comes back to bootloader).

How I fix: Then I downloaded stock recovery for 2.20.40.90 and install stock recovery. Only then my stock recovery comes back normal.

Next action plan for unlock, TWRP and CM:

1. Downgrade to 2.19.40.20 so that I can unlock bootloader

2. Unlock bootloader (already rooted)

3. install custom recovery (twrk unteathered)

4. Then CM12.1

Well I'm having problems! I managed to downgrade to 2.19.40.20 succesfully - but when it went to normal boot, nothing works, a pop-up saying "android.process.media has stopped working" keeps showing up constantly, can't even do anything.

I figured this was normal, so I went through with rooting - I downloaded the 1-click thing, and tried following just what the thread said. I ran CheckBeforeAction.bat, and after it finished it rebooted the phone in recovery mode. But now that I want to run root.bat, the phone isn't showing in the adb devices list! I have NO idea what to do, since I can't root, the normal boot is screwed up and so on! Need help!

Until I used this tool you shared, simple simple simple, noobs can do it easily. Bootloader unlocked in seconds, white splash screen was achieved, so then it was obvious, install TWRP of course, and BOOM first backup image completed with all my settings and Factory Rom.

212 seconds for a complete backup btw :D
