Maybe it's that I flashed 13 then took OTA 14 and flashed prerooted 14 system. No biggie, was just wondering why.
[ZenFone 2 Q&A, Help & Troubleshooting] sorg:
Nope. Correctly update 2.13->2.14 is exactly the same as fully flashed 2.14.

Special attention should be paid to recovery version because even if you flash full firmware (downloaded from ASUS site), recovery image will be updated through delta-patch. Thus, once missed correct sequence for recovery update, you won't correct it in the future firmwares. So, you need to check recovery version and make sure it's v2.14 as well.

ASUS uploaded full v2.14 firmware, so you can refresh phone firmware.

Just to clarify, will rooting through this method wipe any of my data?

[ZenFone 2 Q&A, Help & Troubleshooting] tsam19:
I am under the impression the ZE550ML zenfone 2, I have, is that the boot loader is locked.

As it is proving impossible to root it using the pre root images available.

I have downloaded 2 sets twice over from the same place everyone else on here is using.

I have 2 sets of instructions that I have followed to the exact method, yet the phone will not root !!

1) ADB sideload method, in recovery mode, choose the ADB option. Zip file is in the folder with the ADB + fastboot files.......................................message in command is "unreadable zip or not recognised'......

Checked ADB device and ADB recognises zenfone attached to computer!

2) turn phone on and have debugging set.......................(no recovery mode) place system.img into fastboot folder...........open command via the shift + right click option............submit the line 'fastboot flash system system.img.........................continuously waiting for device......nothing else

Ive never known a more difficult phone to root, especially with all the easy straight forward instructions out there to follow.

So I'm of the impression the bootloader or something is stopping root

Anyone else had the same issue?
[ZenFone 2 Q&A, Help & Troubleshooting] graphO:
For that method the phone needs to be in fastboot mode (turn phone on by holding down power + volume up buttons, when it vibrates release volume button) i.e. the screen before recovery mode.
[ZenFone 2 Q&A, Help & Troubleshooting] tsam19:
graphO: Tried it ALL ways possible and nothing !!

You also mentioned hold down power + volume up, wait for vibration then remove volume up key.....................thats not correct !

Its remove power key and keep holding volume up key !

Even tried the other asus flash tool method.

I've tried all / every possible ways in the correct ways described in the posts and instructions.

As already stated. :good:

Alright so basically I am on 2.13.40.13 and i would like to upgrade to the latest version which is i'm pretty sure 2.15. I rooted and updated SU Binary which i realize makes it so my phone will go into a bootloop if i did the OTA. So i was wondering how i would go about of doing the update?

My device rooted when i check with root checker.

But i cant use app who need root access like xmod, gamecih, or game killer.

Anyone can help me to fix it?
[ZenFone 2 Q&A, Help & Troubleshooting] lesmo_sft:
Yeah, so I think OTA changed CN to WW automatically for some people, though. I'm not sure what's up there. Asus website is VERY clear about making sure you update your WW to WW firmware... although I haven't seen anything about CN updates. Just a JP 2.15 version popped up.

The other files are just for some other system stuff. I'm learning as I go, but as far as I know by now system.img contains the Android image + Asus apps and pre-installed bloat (this is where the root is installed), and boot.img contains the kernel. The droidboot.img contains the fastboot environment (although I'm not sure), and I'd highly recommend to avoid flashing that because some guy did and he bricked his Zenfone. I presume recovery.img contains files needed for... uh, well, recovery when doing a reset from the settings or key combination (but again, I'm not sure).

Personally I've just flashed boot.img and system.img, and so far I've had no problems. I left the other partitions untouched.

You can safely flash 2.15 over 2.13 and updated SuperSU, but I recommend you remove root before doing it. I've done that myself. Updating the SuperSU binaries makes your phone go to bootloop if you update via OTA; if you update by directly flashing from your PC, that doesn't happen. OTAs only download and install diffs/changes/"deltas" (if you will) of system files... because you've messed with system files by rooting, your system files no longer match those Asus is expecting you to have, so when an OTA is installed... well, you break it.
[ZenFone 2 Q&A, Help & Troubleshooting] MrKoji:
If SuperSU is not updated is it okay to get OTA while rooted? & if we will unroot.. Can we root it same way after updating? Will it still be okay?

[ZenFone 2 Q&A, Help & Troubleshooting] gopzzz:
Follow these steps...

Files needed

1. prerooted system.img file - You have it

2. Flashtools.zip - containing files for flashing the img files

3. relevant recovery.img & boot.img [ Note: donot flash droidboot.img as it is not needed and risk of bricking your phone]

Steps:

1. Switch off your phone & then switch on to enter fastboot ( hold vol up and then Power button.... wait until vibration then leave the power button but continue to hold the vol up button)

2. Wait for few seconds to see green android with fast boot screen written small in yellow... stating waiting for connection

3. connect the phone to the pc/laptop and wait for few seconds...

4. unzip flashtools.zip in a folder and place the recovery.img, boot.img & system.img in the same folder

5. press shift + right click >>> opens a dialog tab>> select open command window here

6. cmd opens with the names corresponding to the same folder...

7. type in

fastboot flash recovery recovery.img

fastboot flash boot boot.img

fastboot flash system system.img

wait and do one by one.... while flashing the system.img your cmd box will show split files being flashed... wait till 4 - 5 files being written....

Once finished... look into your phone for the completed and done

disconnect the phone and then press power button to reboot.... DONE!!!!! you will be in the new firmware.... Hold not to update the SU binary... wait for the OTA update or for further support...

[ZenFone 2 Q&A, Help & Troubleshooting] AccaOC:
Guys I have some questions, my knowledge on these things it's limited, I hope you don't mind me asking :D

In the main thread the instructions changed over time, I understand they are given to avoid problems, but I'd like to understand.

Given my phone is fully updated, If I want to root should I flash recovery boot and droidboot too or flashing just system.img is enough? I should already have the right boot,droidboot and recovery installed (by the OTA) on my phone, right?

Once I've flashed system.img, as long as I don't update the binaries, I can install the OTA, so this means that with this method the root procedure it's a "only once" thing, right?

In the main thread it's said that if we modify the system files the ota will fail and bootloops will accour, this is limited to the system files updated by the ota, not to anything, right?

If I install busybox, xposed, adaway etc, as system apps can I OTA? If I can't OTA to update I should reflash pre-root image, but that is missing what I've added so I would have to reinstall those things.

Last question, maybe a stupid one, what is it that prevents us from modify the OTA file and add supersu in it?

Guys thankyou in advance for the answars :)
