Flashing phone.

After an hour of usage, the phone randomly vibrates and screen flashes with the background wallpaper, making the phone unusable.

After restarting, it's okay for a while, after i launch some apps (like Torque) it starts again.

Any other has this problem?

**(On every reboot, the dialog of "Android is upgrading" appears).

Doing the whole thing from the start, see if it occurs again.***

Hi, thanks for the useful guide. Just one question, If i flash the prerooted system image, then I don't have to flash anything else, right?

Also, how do I update to the new system version afterwards without losing data?

I believ thats common sense where when you install OTA file.zip via notification. that will override droidboot which will recover fastboot

OTA update wont pop up

I am looking for "system.img" on that MEGA folder but cant find it. Would you please attach the Z00A_WW_2.15.40.13 rooted system.img? I traid to change the CN to WW but the OTA update won't pop up.

I've done the following:

- i bought a CN Asus Zenfone 2 ZE551ML,SILVER,LTE,D Z00ADB (in the "about" I see the Z00A phone version)

- Skipped all steps till I got to the change CN to WW in this tut http://xdaforums.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596

- flashed the 3 files via fastboot

- reboot the phone

- copy the UL-Z00A-WW-2.15.40.13-user.zip as UL-Z00A-CN-2.15.40.13-user.zip to the phone

- unplugged the USB

- reboot the phone

- nothing happens

I will try the system.img if provided, but I don't really know what is wrong, if skipping the steps or something else.

Thanks.

[ZenFone 2 Q&A, Help & Troubleshooting] vivix:
you can also fash system.img via fastboot and then copy OTA to phone so pop up will show.

So after applying OTA you will lose root but you will be on stock.

Power up and volume just takes me back to Fastboot.
[ZenFone 2 Q&A, Help & Troubleshooting] flashhammer:
I think thats because a difference between the img versions you have flashed.
[ZenFone 2 Q&A, Help & Troubleshooting] oXydead:
I installed the img from the first thread, without installing the ota so I can keep the root.
[ZenFone 2 Q&A, Help & Troubleshooting] flashhammer:
I've managed to install by lastly flashing the system.img, then copy the file to the phone and installed it.

ASUS USB Drivers

Hi Vivix,

THanks for the clear instructions. Followed them and my phone does not spot the update. Figured out that it is probably the USB drivers as ADB does not list a device. (which seems strange as the flashing of the images in the first stpes of your instruction seems to work. the phones responds and adb claims succes)

So i want to install the asus drivers but the file in your link does not seem to have any executable or anything. tried to update the drivers of the ISB using device control but that also doesnt work as windows claims there is no newer or better software to be found.

What am i missing?

Regards,

hello.. i just bought zf2 ze551ml yesterday, and its on latest WW version 2.15.40.13..

i already read the thread, but my question is, must we download and flash the whole pre-rooted rom to get it rooted?

is there any other way to root it without reflashing the latest rom ( I mean by using the current stock rom)?

Help

hi all, im new in here.

just a couple of questions, i bought a zenfone 2 a couple of days ago, is a Ze551ml 64 gb 4g ram, 2.3 ghz intel atom, version cn, that is the problem is like a lot of the ones that have been posted here, i bought it from china, and i have build number z00A-2.13.40.13.

A couple of questions, does mi zenfone 2 was flashed or rooted, or what, because they change it from cn to ww.

wich is fine im from Mexico and tnx to that the h+ works.

but the thing is i wanna install the latest update, but after reading all of your coments im getting confused, wich version of the update will i install it, the cn version or ww version.

do i need to install version per version, or installing it the most recent one will be enough.

also ive recently upgrade a padfone 2 from 4.1.1 tw version, to 4.4.2 tw version, but all i did was download the update from asus support and put inside the padfone and inmediately said you have an update. wouldn be the same with this device.

sorry for the long post, and tnx in advance.

---------- Post added at 11:28 PM ---------- Previous post was at 10:42 PM ----------

hi, your phone was rooted when you did this, then you think that maybe my zenfone 2 that i just bought and is cn but converted to ww, its my understanding that the sellers in china do this, then my zenfone model asus_Z00AD, wit build number ww-asus_Z00A-2.13.40.13_2015401_8390_user, maybe can be updated with only puting the recent update from asus, and putting thta update in my phone, and restar it ti, you think it would update?

hope someone can answer me, tnx.

You flash via fastboot latest firmware files (recovery.img, boot.img and droidboot.img) to change region from CN to WW . If you want root then you flash via fastboot latest pre-rooted system.img or if you dont want root then you flash via system latest OTA. you ca find these files at MEGA folder (1st post)

I got this same problem too as a result of doing the same thing. I am able to enter fastboot but when I choose Recovery. It goes to the error screen and upon pressing Vol+Power a couple times, it displays a series of failed commands (cannot get a picture of it right now). I tried reflashing recovery, droidboot, boot and system images as in the tutorial but no luck. It still gives the error upon booting and I still cannot access the recovery even though the files seem to have flashed successfully.

I would really appreciate any help also

[ZenFone 2 Q&A, Help & Troubleshooting] tmrev7:
Thanks for the response. I did the following based on what you said and got the following screenshots (sorry if they are a bit unclear):

1. In fastboot I flashed - recovery.img, boot.img, droidboot.img and system.img. They all flashed successfully.

2. I then selected to boot into recovery which lead to the error screen and upon pressing the Power and Vol buttons, I got the following list of errors and was therefore unable to reach recovery to choose to wipe cache or factory reset.

View attachment 3323507

----------------------------------------------------

EDIT : I managed to solve the problem and boot into recovery (which was caused after I tried to wipe the cache) by doing the following.

1. I downloaded the boot.img, droidboot.img, and recovery.img of WW_2.15.40.13 from the MEGA link

2. (Following from the guide posted) I booted into fastboot and plugged in the phone to my computer and entered the following commands to flash the various stuff -

fastboot flash recovery recovery.img

fastboot flash boot boot.img

fastboot flash fastboot droidboot.img

fastboot erase userdata

fastboot erase cache

fastboot reboot

I was then able to boot into recovery and flash (I'm still flashing) the stock WW_2.15.40.13 firmware via ADB. (The firmware was downloaded from ASUS's website)

I believe the problem solver was the fastboot erase cache command. I hope this works for those in the future.

EDIT 2 :

I can confirm this works and I am able to boot back into Android normally.

I believe it can also be modified to use the pre-rooted system image by using the appropriate fastboot command

Can you tell me how to flash original firmware? i downloaded it from asus but there are not .img files.....................
[ZenFone 2 Q&A, Help & Troubleshooting] tmrev7:
I used my computer for this but there's another method using your SD card both of which can be found on the thread titled "Asus Zenfone 2 | Resources all in one thread" so credit is due there.

But the steps involve:

1. Boot into recovery

2. Select apply update via adb in the recovery options

3. Plug in your phone to your PC.

4. Use the command "adb sideload file.zip" where file refers to the name of the firmware zip you downloaded. This step takes a while (about 10 minutes) so don't rush it.

For more detailed instructions, check out that thread

The 3 one ftom the WW_2.17.40.12 folder???thE whole Z00A.WW_2.17.40.12 folder?or just the 3 files from that folder???I'm asking that because i have the ww 2.13.40.13 rom.....

Vivix, that'exactly what I did, with no error at all...but no OTA....at thw 3rd step I didn't flash the image because I didn't want the prerooted rom......can you suggest anything else???? Romeri did that via adb sideload, but I don't know the exact steps.....I mean how to rename the .zip file , whether is hould extract it and where...

Everything with the drivers is just fine!!!

II. Downloading Required Files

** Necessary tools and Drivers - Mediafire Folder (Everything OK!!!)

**Latest OTA form ASUS website : WW_2.17.40.12 (Downloaded OK!!)

** Boot.img, Droidboot.img and Recovery.img from this MEGA Drive posted by Chinaphonearena user and belong to Shakalaca. (Downloaded OK!!)

** System.img - if you want your phone ROOTed on latest ASUS ZF2 Firmware. (I skip it because i don't want my phone rooted!!)

III. Yeah! Im ready to do it

**Plug in your device to your PC using a USB cable.

**Boot your device to fastboot mode Power + Vol Up to enter Bootloader Mode

**Hold down Shift and Right-Click anywhere in Fastboot Folder on your PC and select Open command here. It will launch a Command Prompt Window for you to issue commands to your device.

**When it launches, type in the following command and press Enter (.img files has to be in same folder as fastboot tools):

fastboot flash recovery recovery.img

fastboot flash boot boot.img

fastboot flash fastboot droidboot.img (So far no error at all!!!!!)

fastboot flash system system.img - Only if you use Pre-ROOTed system image from MEGA Drive. (I skip this step because i don't want my phone ROOTed on latest ASUS ZF2 Firmware and have skipped the system.img at downloading)

Everything so far perfect...then i put the file UL-Z00A-WW-2.17.40.12-user.zip or with the CN naming at the memory phone, NOT in any folder, just at the memory phone, and nothing happens.... :( no matter if i restarted it or what...........

any help would be super!!!!

I never tried to update using OTA on unrooted system.img . Even when you flash original OTA drom ASUS im not sure if you recieve OTA. I readed somewhere that if you tried to update on ROOTed device first then on server of ASUS you left signature which tells them not to send OTA on your phone anymore. if that make any sense. Im not sure if thats true or not.
[ZenFone 2 Q&A, Help & Troubleshooting] OraXdaDevelopers:
Please back to my question.

Now I have read all threads to this point.

I like to root the phone after successfully installation of the last OTA update. I like to sure, that the migration to WW version is successfully finished.

Steps:

1 Fastboot flash of recovery, boot, droidboot

2 adb sideload last OTA update

3 cache and data wipe

Right?

Beside:

The stock recovery tried to install an update.zip from /discard/ which does not exists:(

Reason of failure?
[ZenFone 2 Q&A, Help & Troubleshooting] vivix:
Why do you want to install OTA by sideload ? Just follow steps from 1st post. If you want ROOT just follow 1-3
[ZenFone 2 Q&A, Help & Troubleshooting] OraXdaDevelopers:
Because the copy of OTA zip to top of internal phone memory does not work. No notifier message!

The stock recovery does not found the zip too.

Question: The unpacked size of system.img is really over 2 GB? I have unpacked and merged with the rar tool.

Edit:

Now I have tryed with the sideload, but I got the error messages

Any idea?

I think it is better to flash the pre_rootet system image with the newest version:)

But the size is unusually big?
