Shares

Unlocking your bootloader allows you to put custom software onto your device. Many developers have created custom ROMs and have had to hack their way into the ZenFone 2 to make this available to powerusers in the community.

Now, unlocking the bootloader is as easy as downloading the utility, installing it, and running it.

Proceed with caution and read below notice before attempting

    • How about you guys finally releasing android 5.1.1 or 6? I was happy with my asus purchase until i saw the bad battery life due to android 5.0 and all the bloatware added… Android 5 has a lot of issues, will the company ever release the android 6 update for the zenfone 2? or 5.1.1 at the least?

  1. It is unacceptable that the company provides software for the use of their clients and say that this software interrupts the warranty !!
    it is a crime against the consumer! Create shame in the face and release the update to 5.1.1 nothing ….

    • Unlocking the bootloader voids the warranty since we would like you to stay stock and enjoy what we offer. Basically, if you mess up your phone, it’s on you. Many in the modding community would agree with that. It’s not a crime especially when we warn you ahead of time that there are consequences. With regards to 5.1 or more recent OS versions, demands don’t help anyone. However, I’ve asked the team at HQ to provide a roadmap of updates. Enjoy your Zenfone!

      • If the Asus think the rooting process or bootloader is “illegal” or should not be done, you can not provide tools for it!
        Anyway any software or tool provided by the manufacturer could break the Product warranty!
        Okay of installation of an alternative firmware break the warranty , however only use the process of rooting or bootloader to make some blocked options available can not break the warranty!
        For example, there are N software that are not used by many customers and it is only possible to remove them after rooting the device! that while keeping the original firmware.
        if I paid for the device I have the right to decide WHAT want to or not 3rd software inside it! and these 3rd software uninstall option should not come locked from the factory!
        These 3rd software and the lack of system update is WHAT takes 90% of the common users to do root on your device and install an alternative software.
        With so much “junk” placed on the device have forgotten the basics, as a low-latency audio “driver”, same are the ASIO audio drivers (available for Windows, Mac and Linux) what would help a lot in audio and multimedia professionals. Apple and Samsung devices have technology for audio “without” latency on your devices

      • I used the bootloader unlocking app yesterday (10/14). I am unable to get to the bootloader screen pictured above. So doing anything with other roms is out of the picture for me at this moment.

  2. I’m on latest firmware, installed utility and accepted terms of use. Ran utility but I get an unlocked failed message. Is my phone now without warrantee even though your utility fails???

    • Hey Guelo, no your phone should still be under warranty if the utility fails. I’m not sure what caused the fail, but do you have all the original apps enabled/disabled, or are you completely stock?

      • Well, I was rooted. I assumed that may be the issue so I unrooted and did a system recovery, continued having the same problem. Might it have been that the phone was rooted?

        • It might have something to do with that, I’m not sure. I’m going to check the XDA threads and with our HQ team to see why sometimes we get the failed notification!

          • I have the same issue – stock ZenFone 2 with some of the default apps disabled, never rooted, fully updated.

            Using the unlock utility gives me an “unlock fail… rebooting in 5 seconds.” Whenever I try to start it up in fastboot, it’s locked in the same failure and message loop even without queuing another unlock attempt.

          • Yes, I was able to duplicate the issue and sent the info to our team in HQ to see if they can fix the problem.

  3. Why would they release it if it doesn’t work at all? Haven’t read of a single instance where it was successful. Leads one to wonder what the purpose of this really is….

  4. I too am having the same 5 sec error. I have been going it it since yesterday with no luck. I guess we have to play the waiting game now.

  5. Same for me. Tried a variety of options to see if I could get the unlock to succeed but no luck. On latest firmware (2.20.40.97).

  6. Phone : ze551ml
    Firmware : 2.20.40.97
    Installed the APK to unlock bootloader from Asus’ website. I have the inverter Asus logo. I am unable use faatboot, I get the unluck successful….reboot in 5 seconds.
    This defeats the purpose of using the unlock tool if I cannot do anything with the phone. I cannot root it, I cannot change the recovery, I cannot change the OS. Is the bootloader really unlocked?
    I tried to load via adb sideload, nothing works.

    Asus Khang, if there is a fix, please let us know.
    Anything that can make the faatboot work again

  7. I can’t seem to get anything to save to my sd card through the phone itself..any tips on of this bootloader would let me do that? I’ve already tried the Asus custom settings and it doesn’t work.. also there’s half of my Rom that is unused but it won’t let anything save. It says system reserved space.. any help or solutions would be great

    • Hi Ray, Please correct me if I’m mistaken – You want to save media files, apps, etc. to your external SD card, but you are unable to? You went into ASUS Customized Settings > App Installation Settings > Prefer external storage and that didn’t do anything? In the bootloader, I don’t believe there is an option to fix that for you. In the system reserved space, that is dedicated to the OS and all the necessary components to run. You won’t be able to save anything there. Can you screenshot your Storage for me?

    • Unfortunately not yet! But I’ve been looped in on some communications regarding the value of the community and what we can do to help everyone.

  8. I am also having boot loader issues …
    Now I cannot go to fastboot mode it always fails and reboots
    please update us when you find a fix !
    Even a fix that will not unlock the boot loader just allow fasboot not to reboot will be great
    I can add that while I tried this I had 2 Sims installed and an 8 GB SD card.. if it helps.

    Thanks,

  9. I understand unlocking the bootloader voiding the warranty, even though I don’t agree with it (the theory supposedly being that installing an alternate ROM could actually cause physical damage to the HW, which is highly unlikely – even ‘bricking’ a device by flashing it is usually just putting it into a state where you can’t get a response from it to reflash or recover without resorting to JTAG or other extreme methods)

    However, I really do think Asus hasn’t really thought through this position on no more software updates just because you’ve unlocked the bootloader. Obviously I could see no SW updates if you’re running a modded ROM (and likely if you are, you don’t WANT those SW updates at that time), but if you want to go back to stock and check out the latest release of official from Asus you should be able to. Just because the bootloader is unlocked should not prevent you from re-flashing the stock ROM and then getting Asus SW updates. By taking this position, Asus is essentially saying once you leave our SW you can’t come back. That’s damned short sighted if you ask me, since it prevents people who maybe want to give the stock Asus SW a 2nd chance from doing so.

  10. My phone is still broken because of your unlock app ASUS. Are you going to fix this? Notification said unlock failed. Wil you replace my phone?

    • Hi there! Our team in HQ is working on a fix for this. Please be patient, but know that I do understand how frustrated with this you might be. I will keep everyone updated on the progress.

  11. Boot loader unlock is crap….probably why my call screen has been locking up along with other issues since used. Anyone interested in filing a class action suit with me.

    • It was reported on a handful of devices. There is a thread on XDA for an unofficial fix, but our team in HQ is going to follow up with an official one soon. What exactly happened?

  12. Here is hoping that we see a ZenFone that works with all major US carriers GSM and CDMA (AT&T, T-Moble, Verizon, and Sprint), like the MOTO-X Pure, Nexus 6P, and Nexus 5X.

        • It said root successful, or unlock successful? because the tool should only unlock the bootloader for you. It’s good you got the white splash screen though. That should mean it is unlocked. But doing so won’t give you root. How did you flash TWRP?

          • Typo. I meant “Unlock successful… rebooting in 5 seconds”

            Splash screen is white, bootloader is still stuck in a loop and I cannot flash in TWRP.

  13. I also have the unlock successful rebooting in 5.

    I’ve tried just about everything I can think of and unfortunately haven’t been successful with the Level99 method.

    adb sideload works for me, but I was already on the latest version and that’s all I can load successfully. If this is solely a US problem is there a way to switch to the CN packages?

    Or alternatively, can the team release a zip with TWRP that has a verified signature that adb sideload will accept? Since, it looks like the verify signature portion is where it fails.

    I don’t know, I’m not a developer or anything. Just hoping this can be solved sooner or later since the latest update messed up my modem and I can no longer get on the data network, which is what prompted me to unlock my bootloader.

    • Hey Robby – Sorry to hear that you ran into that issue! We should be getting an OTA soon that will help to fix the reboot issue. Since you can ADB sideload, wait for the OTA. Level99’s method seemed to work for most, even myself who admittedly isn’t the most technical person. We also can’t release a zip with TWRP.

      • Well at this point, and for some time now, my smart phone is just a phone (thankfully I had the 2G SIM slot). Is there a rough idea of when the next OTA update will be released?

        • Hi Robby, I wish I had a timetable for you. The HQ team understands how important this next OTA is and will release it – I want to say in the next week or so. They still need me to test it based on the unlock error, but they haven’t sent me the OTA. If I find that it’s still causing some issues, it might delay it.

          • Well I appreciate you giving a rough estimate. Please let us know on the XDA thread when you start testing. I’ll check back there to see how it’s going.

    _thirdly the possibility of a shortcut file on the home screen no longer exists, it was pretty awesome why ASUS has he removed this feature
    _fourthly the music volume is low. taking pictures is disappointing night photos taken at night are unreadable 13mg of pixels is far from reflecting what we have known for example with the Nokia N8. Bluetooth sharing no longer works here 5.0-2.20.40.130_20151104_25 version 43user

  16. Hey Khang, did you get a chance to check with your team at HQ and find out whether or not a bootloader unlock tool is in the works for ZE550KL?

  17. ive had a problem with my recovery fron the day i bought the phone. whenever i try to boot into recovery i get error. i have to press volume up and power buttton which will take me to recovery. i unlocked my bootloader lastnight and i keep getting rebooting in 5 seconds . the ze551ml 2gb will not allow me to root or install another recovery to see if i can fix the issue of rebooting issue whenever i try to go into bootloader.

  18. khang thai… followed the steps on the link u posted and it worked beautifully, it really does work, thank you. it took a couple of tries to get there but it worked.

  19. I must state that after using the “fastboot flash recovery recovery.img” command using android sdk tools. the phone says failed, permission required.. or something like that but when I disconnected and rebooted to recovery ..twrp recovery was actually installed even though it said it failed. i flashed the superuser zip file through twrp and it also rooted the phone beautifully without issue. now when i boot into recovery i no longer get an error message and no more boot loop when i boot into fastboot mode. i will now flash a custom rom and report my findings.. thanks to the xda developer guys also.

    • Yeah it’s kind of funky how it works, but I’m glad the XDA guys were able to assist there and come up with that solution! Happy flashing!

  20. How funny that the phones tech/support team has to refer to xda for help. This app doesn’t work on ze500cl. Was att zf2e, flashed Asus fw, with tethered cwm, 118. Maybe something about unlock servers are down

    • It’s actually amazing! Love the community and sometimes the development, tweaking is done much faster than we can do at HQ.

    • Hey there! I got word from HQ that they are finalizing their update schedule next month. I’m hoping they’ll release it publicly at that time.

  21. OK, this is a bunch to type and I’m so dumb technologically but here goes,hope u can help. My son bot Asus zen2E att and online I paid to get unlock code.success. he starts service with family mobile, runs out of data. Thru settings he then shuts off WiFi and data. He changes pattern lock goes to sleep and promptly forgets next day. When I follow directionsfor ffactory data reset, I get no option to do so once entering recovery and choosing it. Only options are reboot then install from adb then install from micro SD card. WHY WHY WHY CANT I GET FDR OPTION OR WWIPE DATA OR THE OPTIONS PEOPLE AND BLOGS ALLAY TO?!? PHONE USELESS FOR WEEKS NOW… JUST WANT TO KNOW WHY THIS FATORY DATA RESET OPTION IS MISSING AND WHAT TO DO NOW? HELP AND THANK YOU TONS IN ADVANCE.

  22. I have a prepaid AT&T ZenFone 2E. Will this work the same for this phone as well? Is the 6.0 update scheduled for this phone at the same time or will it be left behind or later? I too am having problems on 5.0 with it being very slow and cumbersome even compared to my previous BLU Air.

  23. my phone is asus zenfone 2
    and system isx 2.20.40.138
    i tried to unlock boot loader using this method
    {

    adb shell
    su
    getprop ro.isn > /factory/asuskey
    reboot bootloader

    }
    and it’s not working
    please help me

  24. I tried to run the Unlock Device Tool app, but doesnt seem work. I didnt see the white splashscreen.
    Even worse, I can not go to fastboot (bootloader) mode, instead I see a black screen with a USB logo shown.
    Is there any way to get into fastboot/bootloader mode in my situation now?

  25. im not sure if this has been anawered already or not, i havent read the entire.thread yet but, is there a way to unlock thw bootloader on the Zenfone 2E ZE500CL, ive searches the internet and mostly find tos that help every model, except for mine. the few ive found that claim to be for the ZE500CL turn out to be for the 550 or 551…any information would be helpful.

  26. We had the same problem with my recovery ever since we got the phone. Whenever we try to boot into recovery, there is an error. We had to press volume up and power button to go in recovery.

  27. Just wondering what the current state of the boot loader unlock tool is. Have the issuses people were experiencing been resolved? If I run the tool on my ZenFone 2 now is it likely to cause problems, or is it working ok for most users?

    I fully accept the risk that comes with unlocking and I applaud ASUS for releasing it. It would be nice however if you could offer a way to restore it back to original condition. Is this possible?

    Thanks for any advice that can be offered.

  30. […] Son derece ilgi gören Asus ZenFone serisine son olarak çok sayıda ZenFone 2 modeli eklendi ama daha önceden olduğu gibi bu cihazların başlatma sektörü olan bootloader ile koruma kilidi geliyor. Bu yüzden özel tip ROM paketleri yüklenemiyor. Meraklı kullanıcılardan biriyseniz ve Asus ZenFone 2 ile farklı ROM deneyimini tatmak istiyorsanız Asus ZenFone 2 Bootloader kaldırma aracını denemelisiniz. Merak etmeyin bu araç Asus tarafından geliştirildi ve Asus ZenFone 2 kullanıcılarının dikkatine sunuldu. Asus açıklamasına göre bu aracı kullanmadan önce kullanıcıların Asus ZenFone 2 yazılımını versiyon 2.20.40.59 ya da üstüne terfi etmeleri gerekiyor. Asus'un bu adımı özel ROM paketlerini geliştirenlere destek verdiğini gösteriyor.
