Bootloader question

Hello Zenfone2 community,
I'm still a little bit noob in the android world, so there are a few things that are a bit abstract to me, so, let me start to explain why i'm here.
Earlier this month i rooted my device, unlock BL (unofficially) and installed Cm13, but i found a dead pixel, so i want to send i'm to warranty.
So, today i started the proccess backwards, first i reverted to stock, then i flashed blacksplashscreen, then i "uninstalled" twrp, and finally i flashed raw (with asus flash tool) then flashed recovery, droidboot and boot and adb sideload .97.
My question is, did i really relock bootloader ?? How do i test if my bootloader is unlocked ?
I already updated, (placed the zip into internal storage) and it showed that i had a new update ? Does this mean i have ota working ?
Cumps

Bootloader once unlocked remains unlocked unless u decide to update to MM Beta
Unofficial bootloader unlock = will get ota updates
Official bootloader unlock = ota not allowed(u can update manually)
To check if ur bootloader is locked or not, just flash a custom recovery & boot into it, if it boots ur bootloader is unlocked if not its locked simple
Plz move ur thread to Q&A Section or ask a Mod to do it for u

so i heard that when you flash raw file , your bootloader will locked. you can try that then take your phone to asus service center to claim warranty.

Send ior to repair, they will not notice that you unlocked

If I used the official unlocker and update to MM beta will I get OTA updates?

Nope they will have ur serial no & u will be barred from getting ota

Sideload Marshmallow from Lolli 1.17.40.1106

Hi all,
needing help upgrading to MM.
I'm stuck on 1.17.40.1106 since I unlock the bootloader I can't receive further updates.
I've read that to be able to upgrade to MM you need to have .1531 firmware but since I'm stuck, can I sideload MM 21.40.1220 from Lolli 1.17.40.1106?
I have TWRP installed but not rooted.

First if you want sideload u must in "STOCK recovery"
And Seccond if you want update to MM u must have final firmware of LL. Go to asus.com check ur firmware version, If you are using last LL u just download MM firmware copy to sdcard and go to recovery-->apply update from sd card-->choose firmware MM and wait it update
.....
Dont flash firmware of asus.com if u use custom recovery it will brick your phone....

Thanks Val.
I'm having status 7 error both in stock recovery and twrp, another reason why Im stuck.
What are my options?

anyone?

you have twrp but no root? how does that work?
in any case, the Terms of Service of the Asus unlock tool says you will not be able to get OTA update after using. We have confirmed that the unlock tool communicates with Asus when you use it - we highly suspect it sends your phone information to Asus to prevent official OTA.
I would root phone and install ROM.
check this out for issue of installing official MM update with TWRP:

Thanks Eric.
I was reading the links you gave and have this questions:
1. Is it true that if I use custom recovery (TWRP) to sideload official firmware my phone will be bricked?
2. If I do "fastboot erase system" and flash full official firmware such as 1.17.1531, will it erase the custom recovery and go back to stock?
This way I can manually upgrade to MM once in stock recovery.

1)i think twrp will not flash the official firmware, like if you downloaded it from Asus or got the ota .zip.
2) i do not know that command but it scares me to look at it.
in the thread i linked to, was answer to y question about flashing the official MM stock image.

[Guide] Safely unlock bootloader on official MM

UPDATE: This is now unneeded because threr is a faster way ro unlock bootloader on official MM here, he updated for official MM
Hi, I discovered an unlock method for official MM!! This maybe long but's it totally safe
You need:
Adb and fastboot environment ready PC
LP RAW File
Android 6.0 Beta Unlock tool
Android 5.0 One-Click Unlock tool
First version of beta MM (Z00A) (Z008)
Official MM zip (find it on Asus site)
Thanks to all people upload these links
Just do the following:
Flash the lastest LP via AFT (using raw file given above), wipe all data. If you already on MM, you have to downgrade
Unlock your bootloader using 1 click tool given above
Boot to stock recovery and sideload the first version of beta MM
Unlock the bootloader using MM beta unlock tool above
Boot to stock recovery
Two case here:
Case 1: You can't boot stock recovery
Normally boot your phone (to Android)
Setup it as a new phone
If it shows there is a new firmware, don't update!!!
Enable Developer options, then enable usb debugging
Copy the official MM zip to external sd card
Open command prompt, run adb reboot recovery, accept the adb permission if prompted
After it boots to recovery, select Apply update from SD, then choose the zip file you've copied before
Wait for it to update, it may stuck at flashing splashcreen, don't worry, it's trolling you, may be Asus forgot to update the script
Goto step 7
Case 2: You can boot stock recovery
Sideload the official MM zip (adb sideload <filename>.zip)
Goto step 7
7. Flash this TWRP (fastboot flash recovery <twrp>.img)
8. Root your phone using this method
9. Reboot, if it shows "Your phone has failed verification bla bla..", then you've success. It may reset loop like note 7 in the first time start, don't worry.
9. Enjoy :highfive:
Note: If you're facing with battery problems on MM, factory reset it in Settings > Backup and Reset > Factory Reset > Erase everything
Successfully on my ZE550ML
The warning screen is normal so don't worry and there is no way to fix it for now

Yes, BL will be relocked once you upgrade to MM.
If you want to unlock MM BL(6.0), refer to this thread.
Or you can downgrade to Lollipop referring to this thread. Then your BL(5.0) is unlocked.

Upgrade to MM
Hello folks!
2 week before MM was released i'ved opted to unlock my ZE551ML BL and therefore install twrp and a MM custom ROM..
so here´s the thing i stayed with the ROM for about 3 weeks and honestly..it works very well..but when i knew that 6.0 official was coming out i decided to go back to stock..i did it following manny tuturials avaliable for me to get my BL Re-Locked..but unsuccessfully..so i followed mr_gourav2000 tuturial (http://forum.xda-developers.com/zenfone2/development/stock-rom-ul-z00a-ww-2-20-40-168-t3354526) and reverted to the WW_Z00A-2.20.40.183-to-2.20.40.184 (hopefully i can get the sshot in this post) version...since my BL is unlocked i can´t get no updates..my question is:
Is there anyway to go to MM 6.0 by ASUS with the current status of my phone?
is there anything i can do to revert this??
Cheers to everyone

Just download the update package and rename it to mofd_sdupdate.zip, copy it to internal storage. Then reboot to stock recovery, the update will automatically start. This should work if you have lastest stock recovery

Updated the first MM beta link in OP

hello , thanks to your tutorial I managed to unlock the bootloader , I have TWRP version 3.0.0.2 with stock installed but when I wanted to install CM13 and gapps I restarted the phone and automatically returns to recovery again. some help?

Have you downloaded the correct build? There are build for MM bootloader, if you flash the normal builds, it will fail and reboot to recovery again. Gapps is the same for all builds
After you install that special build, do not update to newer nightlies, it will fail. For updates, check the link i give you and see if there is a new MMBL build.
About that, here is the post: http://forum.xda-developers.com/showpost.php?p=68542370&postcount=8551

hello friend, I tried to install the CM13 ROM that indicated me and I get Error 7 in TWRP 3.0.2.0, I have Android 6.0 (.134) official and if I can change kernel and flash rom SuperSU but change with a new MM Blows I can not (CM13, AICP, beanstalk ....) thanks for your help!

Run the script again (i gave you in above post). Download the CM13 in that link, not in the OP of CM13 thread. Flash that CM13 and Gapps (Gapps is universal for MMBL and LPBL).
May be you have corrupt download, I'm currently running CM13 on MMBL

Hello, I have finally found the solution, the problem is the recovery, the TWRP 3.0.0.2 da failure with new builds, I Flashed next on the link you put me through adb and now it works, thank you very much for everything .

how u unlocked bootloader

Q about flashing new firmware updates for Zenfone 3(Ze520kl) with unlocked bootloader

Hey Guys,
I've recently bought a Zenfone 3 ze520kl with the first ever released firmware version and I was also successful in rooting it with twrp installed. Since I used the official bootloader unlocker, I also couldn't receive ota updates. Now, is it possible to flash the newer firmware with a 3rd party app like flash fire and not lose root? i really want to update my phone for stability issues and i've also heard that nougat has just been released. Lastly, do i need to flash the firmware according to release date or is it fine to skip to the latest one?
Thanks for any help.

To do so you have to unroot your phone 1st, in Root guide for 520 in very last step there is a link to boot.img and recovery.img that you have to flash in fastboot, but 1st also in fastboot do erase system amd erase cache, which will wipe whole phone.
https://forum.xda-developers.com/zenfone-3/help/guide-how-to-root-zenfone-3-ze552kl-t3471524/page6
Should you need any help let me know.
Latest firmware doesn't mean most stable... Not for many at least. Im on version .79 which for me is flawless, .152 and few earlier builds it was a disaster.

Hi,
How to install it on a rooted ZE551ML ?
When checking for OTA, it is not purposing the update for the moment.
Thanks

Hello. This forum is for galaxy 8.07. We don't know about zendroid 2 or whatever you ask.
Just joking. This IS for zenfone 2.
I'm currently using the update. Screen flickering has stopped for the time being.

i have a rooted device ZE551ml 2.3gzh 4gb and when i checked for firmware update it starts downloading and now my device is on the update prompt screen i.e. to install , postponed or cancel it.
so my question is :- is it safe to install the updates on a rooted device.
thanks in advance

My way is unroot and uninstall Xposed first, than sideload the whole rom with stock recovery.
I had failed to OTA many times because I modified some system files (forgot to restore them), so now I just reflash rom to save the trouble.

Wifi auto-connect problem seems fixed and the phone has more available ram after "power and boost".
It's worth to update imo.
Battery life seems the same

All sensors working with this version in my brazilian zenfone 2 z00a.

Running this for last two days so far , yup Wi-Fi connects quicker , graphics seem sharper round the web and there's the security patch .
To update ..
Coming from .184 rooted and twrp.
Full unroot first.
Then used the modder tool , to "return back to stock " option. Select boot.img then recovery.img, remember it flashes .134 .img's and I was coming from .184 to begin with.
Then boot to stock recovery .
Scroll to update from adb. Then adb cmd >
adb sideload MOFD_SDUPDATE.zip
Remembering to put the new firmware in adb/fastboot folder first and changing the file name to MOFD_SDUPDATE before sideloading.
Will give it a few more days then will try to use the modder tool to get back to lineage os and back up the new firmware.

I was on rooted .184 and twrp. I booted into fastboot, flashed recovery, booted to recovery, and updated from SD card. After the update has been installed and the phone booted, I unlocked the bootloader, flash twrp, root, remove bloatware, profit

I had unlocked the BL before so i updated and directly tried regaining root and xposed but failed (softbrick at asus loading screen), I confirm that applying the whole ota from sideload sort of relocks the bootloader and you must do it again, now it is booting and rebuilding the dalvik cache.

In conclusion you did only flashed stock recovery and, from that, you flashed the whole zip in the first post, right?

its a add-on downloaded and installed from ` tools ` in firefox browser settings :good:
ps, i had trouble using adblockplus add-on from firefox ,when viewing XDA pages ..they turned out blank , XDA i think prevented the use of such adblock , so now i use the less blocking add-on in firefox called `uBlock`
its good enough
