because if u unlock it with official one, then your build no will be recorded in asus database.. and in future u ll not get any warranty.
[ZenFone 2 General] brentjireh:
did everything on this guide but i still have a black splashcreen instead of white.
[ZenFone 2 General] SH1M4BD3:
Try WindroidTool,works for me
[ZenFone 2 General] brentjireh:
Hello sir. This method eventually worked. I didnt know what was the initial problem. But it worked.
[ZenFone 2 General] scorpion90:
is there a way to relock the bootloder?
[ZenFone 2 General] dh_711:
Nope, atleast not yet.
[ZenFone 2 General] Technical:
Is there a risk on not being able to unlock the bootloader?

If so, maybe I'll have to reconsider on buying this phone...

Are latest versions unlockable? Did Asus kill the ability of unlocking the bootloader?
[ZenFone 2 General] Zilliman:
What does the "unlock the bootloader" do exactly? Is it to allow you to install TWRP ? Does this mean that unless you "unlock the bootloader" you will not be able to install TWRP (and hence CM) ? Or can you install CM another way?

Thanks
[ZenFone 2 General] Perseus:
Thread Closed on OP request.
[ZenFone 2 General] hypertech:
they pulled the 2.19 from their website

i wanted to put the link from asus website, but the forum doesnt allow me.

sorry about that.
[ZenFone 2 General] AkiroX:
Oh wow so there's only a lucky few who actually got to unlock their bootloaders? :c That sucks.

Happy to report though, like all others, unlocked the bootloader.

But I've a question, don't we have like a full dump of it rooted on Mega? Wouldn't it do just to update all the things manually?
[ZenFone 2 General] -fluffy-:
U just need to flash new droidboot then u can unlock bootloader I cutten do it with the old one

Has anybody tried flashing the CWM or TWRP recovery? Is there any reason this wouldn't work now?
[ZenFone 2 General] -fluffy-:
Because it need to be compiled fore our zenfone2
[ZenFone 2 General] XneofuX:
To update, just download all updates from:

http://xdaforums.com/zenfone2/general/ota-links-stock-rom-t3093999 [link for 2.19.40.18 worked 5 min ago]

and flash it manually (simply sideload it), guide:

http://xdaforums.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596 (4. flashing ZenFone2)

There you go, worked like a charm for me (was on 2.18.40.12 before).

And hey! Awesome, waiting for TWRP and CM12.1 (or any other custom rom :silly: ) :victory:

[ZenFone 2 General] bradputt:
great... my 550 will never get this....
[ZenFone 2 General] troy5890:
I feel your pain dude.

Sent from my ZE550ML
[ZenFone 2 General] Christopher876:
You should probably return the 550 and pick up a 551ML 2gb/16gb. The 551 (all versions of it) will most likely be the lead development version (already it is showing that it is favored over the 550).
[ZenFone 2 General] ultramag69:
551ml is 4gb variant, not 2gb... I believe it starts at 32gb but that may only be whats available in Oz...
[ZenFone 2 General] Christopher876:
There is a 2gb/16gb 551ML, I have it.

Both are from the same phone. Z00A= 551ML Z008= 550ML

Besides I have 2.19 on this phone so I am pretty sure it is the 551ML and there is another guy here who posted a guide and he has the same one as I do.
[ZenFone 2 General] MatteXperiaU:
wait. ZE550ML will never unlock bootloader? why?
[ZenFone 2 General] Christopher876:
It needs the 2.19 update which hasn't been released.
[ZenFone 2 General] XneofuX:
Even a 2gb/32gb 551ML which i got ^^

Shouldn't say never ... probably have to wait for an official unlock which may come in the winter. (~3/4 year after phone release).

Thing is, that Asus won't continue to distribute this version until they get it "fixed". The mighty xda was just too fast ^^ 550 probably would've gotten it until now.
[ZenFone 2 General] Christopher876:
I actually have significantly better battery live and performance with this update so I don't see why they are stalling with it and even taking it down. It fixed the system UI crashes as well (which they claimed was fixed in 2.18 when it actually still crashed). On 2.18, I would love 1%-5% on standby every 6-8 hours, now I lose that on standby every 12-14 hours. 2.18, my SOT was around 4-5 hours. Now it is 5-6 hours.

I really don't see what needs to be "fixed" according to them, it might be that they are going to remove the file to unlock the bootloader and possibly another method which could of been found?
[ZenFone 2 General] XneofuX:
Exactly. This is what i wanted to say. :p
[ZenFone 2 General] Christopher876:
Doesn't make much sense as the link to download the update is still live, so whatever they are planning better be worth it.

At least many people got the update (in case they do anything to the update) and prepared for the custom roms.
[ZenFone 2 General] XneofuX:
First: sorry, edited my post ^^ still the quote should be alright.

The update IS hidden now. http://support.asus.com/Download.aspx?SLanguage=en&m=ASUS+ZenFone+2+(ZE551ML)&p=39&s=1

You can just download it when you got the link. Well and what should be worth it? they won't change anything in terms of functionality. Just remove the unlock.

I imagine they want to make sure you can't remove some of the bloatware, which is much easier with a custom ROM.
[ZenFone 2 General] fuzzybuffalo:
The full 2.19 update has never been there, it usually shows up a couple of days after the OTA.

From post #64

The OTA link for the 2.18 to 2.19 is still live on there site

[ZenFone 2 General] saud__19:
I get the following can't create /factory/asuskey permission denied. Any idea?

problem solved thanks guys just access superSU and allow adb shell, in case some one will face the same problem.

:)
[ZenFone 2 General] SBFarooq:
From one Saud to another... Are you doing this on the 2.19? Because this won't work on any of the previous versions...
[ZenFone 2 General] corrsea:
Hi, I didn't get the OTA automatically so I'm currently downloading. Just checking that to install it I place it in root of internal memory and reboot or do I have to place it on an SD card?
[ZenFone 2 General] Kokumotsu:
i need help updating my Z00A to 2.19 through the links provided on XDA

when i try to side load on adb, i get wrong footer error
[ZenFone 2 General] ravian29:
i have read, it should be on memory card but i copied it to both internal and sd card after renaming it
[ZenFone 2 General] corrsea:
I didn't realise you have to rename it. What did you change it to?

Edit

OK got it. Presumably is MOFD_SDUPDATE.zip?

Edit

Got the update message but the update failed unfortunately. Will have to problem solve another day as I've not enough time at the moment[emoji23]
[ZenFone 2 General] saud__19:
yup am on 2.19 the problem related to SuperSu, once adb shell granted root access boot loader unlocked.
[ZenFone 2 General] hkdmjack:
Done. Took me a while because I couldn't grant SU access when prompted. Anybody else have this issue?

Anyway, the first time I tried it I received an error but second time it worked. I kind of like the white splash screen.

I did lose the data indicator in my status bar for some reason, but still have data.
[ZenFone 2 General] bgibson72:
This is nice and all, but...

[ZenFone 2 General] IMSPR69@GMAIL.COM:
No white screen

I did everything fine until reboot bootloader. It re start on recovery but stay on Normal mode for ever. I did turn it off manually and it load normal, no white screen. I did adb reboot bootloader ( press enter) and in fastboot devices is not showing the unit. Any clue?

:D
[ZenFone 2 General] Jhdoubleoseven:
Have the same problem -- try from the bootloader screen booting into recovery and see if it says "Error!". I feel like the problem is that there's an old system update that it's trying to apply which is why recovery is not working...
[ZenFone 2 General] rafyvitto:
Follow my guide here http://xdaforums.com/zenfone2/help/unlock-bootloader-read-fix-t3138837 and you should be able to unlock.
[ZenFone 2 General] IMSPR69@GMAIL.COM:
Yes, I reboot into recovery and it say error. Where may be the update?
[ZenFone 2 General] Jhdoubleoseven:
From the Zenfone 2 resources thread, it tells you how to get into recovery. I'm trying to wipe the cache partition right now and will let you know if that will do the trick to remove the update :)

EDIT: Just tried that, unfortunately no luck :(
[ZenFone 2 General] BOSSPDA:
Erase all data?

-

Hi,

usually, when we unlock the bootloader the task erase all user data, from internal storage. This happens hear? I think it's the same, but I'm not sure. May you enlighten me, please?

Regards
[ZenFone 2 General] ansebovi:
no it didnt erase in asus,i unlocked mine..btw dont quote OP..please edit the ur post and delete or hide the contents of quote..

[ZenFone 2 General] MiCmAsTa:
Phone will only boot into fastboot. (and not recovery)

Manually boot into Recovery Mode, will have a dead android with error.

Anyway to fix this? :confused:
[ZenFone 2 General] mediocre_coder:
to enter recovery mode after seeing the dead android on screen with ERROR! underneath him, press the Vol+ and Power button at the same time, takes a few tries but it does eventually work. then your recovery options will show up on the screen.
[ZenFone 2 General] mongonexus:
hold power than tap volume up once
[ZenFone 2 General] MiCmAsTa:
Thanks for your swift reply [MENTION=2351650]mediocre[/MENTION] [MENTION=4911104]mongonexus[/MENTION] Well, i know that bit. I'm referring to the adb part where it will boot into the recovery? (not?) [reboot bootloader] mine will just stay in Fastboot and does nothing. [Fastboot cmd waiting...]
[ZenFone 2 General] Jhdoubleoseven:
The OP makes it sound like it will automatically boot into recovery and do whatever to unlock the bootloader... It does not do this. Even if we get into recovery, what do we do from there?
[ZenFone 2 General] mongonexus:
are you looking at phone for adb shell toast on phone to give permission
[ZenFone 2 General] -fluffy-:
It won't boot into recovery but into bootloader an say unlock ok or something like that
[ZenFone 2 General] MiCmAsTa:
Able to get su to work in adb shell. Just that after it reboots into fastboot, it just sits there waiting with "Fastboot cmd waiting..."
[ZenFone 2 General] mongonexus:
press volume button select reboot if you see white splash screen ur unlocked
[ZenFone 2 General] mr_thakur:
Nice, I downloaded it but how to flash this file:what::what:
[ZenFone 2 General] -fluffy-:
Are u updated to latest droidboot mine didt the same after I updated to latest droidboot it worked wen I reboot into fastboot just look at the command line it will say fore a short time unlock success
[ZenFone 2 General] MiCmAsTa:
I believe i did update the droidboot.img. But i might be wrong. Flash the droidboot.img again and presto! Done, Unlocked. Thanks [MENTION=391157]fluffy[/MENTION] for highlighting the droidbot.img part.

If anyone of you need the droidboot.img file, i'll link you to it.

FOR 551ML ONLY!

>>> DROIDBOOT.IMG <<<

Disconnect your phone from PC

Power it off

Boot into Fastboot

Now connect your phone

Run ADB

fastboot flash fastboot droidboot.img

Reboot

Then follow the guide by ravian29 to unlock bootloader
[ZenFone 2 General] bgibson72:
So how does one undo this action, or re-lock the bootloader?
[ZenFone 2 General] fuzzybuffalo:
So far, you can not.

Might be able to after Asus releases unlock tool.

---------- Post added at 01:14 PM ---------- Previous post was at 01:13 PM ----------

Your droidboot.img download says I need permission.
[ZenFone 2 General] bgibson72:
Well, crap. :(

I hope it's not the reason I can no longer access the StraightTalk data settings from their app, nor can I receive calls. I stopped getting them around the same time I unlocked...
[ZenFone 2 General] MiCmAsTa:
Sorry, Please try again. :cowboy:

[ZenFone 2 General] ravian29:
i always enter into recovery/fastboot in first attempt, only thing to remeber is "unhook your charging cable"z phone will enter into recovery/fastboot in first attempt
[ZenFone 2 General] ChanManDCLXVI:
I am new to all of this and just had a few questions.

1) Is there any way to check if I correctly unlocked the bootloader.

2) Can I simply use any tutorial out there to install CWM

3) Do I need to wait for there to be a zenfone 2 version of 12.1 CM before installing or is there a generic version that I can just use?
[ZenFone 2 General] fuzzybuffalo:
The first time you reboot into bootloader it will say in blue text bootloader unlocked or something like that.

Your Asus splash screen will turn white.

No, you have to wait for a zf2 version.

Yes, you have to wait for a zf2 version. :)
[ZenFone 2 General] ChanManDCLXVI:
Thank you for the quick reply!
[ZenFone 2 General] Neekapp:
This is good to hear, I almost didn't buy the device because not being able to unlock to bootloader thus making it useless for development. I'm not a developer but I do enjoy new ROMs, mods, etc. and do buy a beer for those ROM's I like. I'll be going to buy my ZenFone 2 within the next hour and come back to try this method. I'm currently using a OnePlus One and the HTC One M9 but the thought of dual-SIM, 4GB of RAM, and Intel CPU really appeal to me. My HTC One M9 battery really sucks and can't leave it unplugged very long and dies before I get home from work. My OnePlus One has the touch screen issue and don't want to deal with the horrible customer service. The touch screen fixes have helped but haven't made it become my daily driver anymore. Blabbing away here sorry just excited to try out this Asus ZenFone 2.
[ZenFone 2 General] GalaxyFan88:
Exactly my thoughts; I exchanged my OPO for the Zenfone 2 a few days ago and have never looked back since.

Even if the OPO has a prosperous community and support through many devs, I can safely say after several days of heavy Zenfone 2 use: this device is clearly better than the OnePlus One. it becomes immediatly obvious after using the sensitive touchscreen, which is a lot better than OPO's seriously flawed touchscreen.

I will sell my OPO asap, it was nice performance-wise but ever since using it and despite its buttery smooth software, I was skeptical about the OPO, especially the touchscreen drove me crazy sometimes.

No more OPO for me; I hope the Zenfone 2 dev community will kickstart since the bootloader is unlocked now.

I believe this thing will get crazy fast when its true potential is unlocked. I'm quite satisfied about its performance already but I can already smell the real tasty custom-candy this thing will offer in the near future. :cool:
[ZenFone 2 General] Kokumotsu:
i need help unlocking, when i enter the command to reboot, it goes to the bootloader but it doesnt update
[ZenFone 2 General] -fluffy-:
Have u updated droidboot ??
[ZenFone 2 General] Kokumotsu:
i guess i havent, i just updated to 2.19 by sideloading, rooted with 1 click and went straight to trying to unlocking it
[ZenFone 2 General] -fluffy-:
Update droidboot then u can unlock bootloader
[ZenFone 2 General] kibmikey1:
After flashing the latest droidboot, the bootloader shows the following text "can not get the necessary info 2" and reboots normally.
[ZenFone 2 General] Kokumotsu:
just updated it and nothings changed =/
[ZenFone 2 General] -fluffy-:
Try like I didt I used get asuskey or what its named don't remember 2 times an the reboot bootloader that worked fore me
[ZenFone 2 General] kibmikey1:
I have a feeling the IFWI versions (token, dnx, and ifwi) play into whether this works or not. Which version of these should we flash to unlock it? There are quite a few in the newest update!

Tokens:

ze550

zx550

ze551

dnx:

DBG

DSDA

SIL

zx551

ze551

ze550

.bin

ifwi:

DBG

DSDA

SIL

zx551

ze551

ze550

.bin

I'm assuming that by updating via MOFD_SDUPDATE (putting this update on your SD card and flashing it in recovery) the standard .bin files are used by default. However, since there's really no way to know for sure, it would help if we knew which ones to flash along with the updated droidboot!
[ZenFone 2 General] peekay2n:
I've not tried this yet.. But my /factory directory doesn't have an "asuskey" file.

Does that mean this unlock method is reversible?

Delete the asuskey file and you're relocked??

PS: I'm asking a question. Not stating what I experienced.

[ZenFone 2 General] Kokumotsu:
do you mean use the command code 2x. i would try that but now my phone go into debugging mode lol
[ZenFone 2 General] Jhdoubleoseven:
If it does't work

I can confirm that for me, flashing the pre-rooted ROM (this includes droidboot.img) allowed me to unlock. It should go like this:

1) Follow the adb shell, su, getprop stuff

2) reboot bootloader

3) Wait a sec

4) Your screen will say "unlock successful... reboot in 5 seconds"

5) You will have a white splashscreen once it automagically reboots

I don't think technically you need to flash the black splashscreen if you don't want. But that's what it should look like if it's successful

I haven't had any luck with sideloading the 2.19 update and get the Error: Device not found in my cmd after I've already installed adb, fastboot, drivers, etc. Cmd sees my device before I try the sideload too. Not sure what the issue is.

now in fastboot mode,it is showing as
