Hello, Im getting to grips with the Asus zenfone 2, with the help of a few of the other forum members on here.
As a previous Samsung galaxy range owner I am familiar with the way you enter either the recovery or download modes.
I have been advised on how to activate the 'recovery' mode (samsung way is easier!).
Now does the Asus zenfone have a 'download' mode?
I am aware of the fastboot mode option (power on + vol up sequence)
Is the 'fastboot' screen the equivalent of the samsungs 'download' mode screen?
Im trying to understand how to reflash a stock rom onto the zenfone 2 or flash the system.img (pre root) file. Ive read many tutorials and they're not quite that clear.
Many thanks in advance.
You can get the Zenfone 2 into the bootloader via ADB (adb reboot bootloader). From there, you can push the preroot system.img file via the fastboot flash system system.img command.

Hi,
I have tested some xposed frameworks' modules and I have got a bootloop (the zenfone shows the background for a second and then reboot).
From the boot mode (power+volume buttons procedure) I have tried a factory reset but it says that there is an error and stops on the "dead robot"..
Now I've decided to flash the phone with its original system image and I've found this guide
http://forum.xda-developers.com/zenfone2/help/how-to-upgrade-cn-version-to-ww-t3101556
At point III the guide says to use
Code:
fastboot flash system system.img
but only if you use Pre-ROOTed system image and then there is a link to the pre-rooted system image.
Where can I find an original system image?
I'm not an expert, I don't even know if this is the safest procedure to solve the bootloop....
please can someone help?

hi, by original system image did you mean the stock system image from stock rom? if it is, you need to download the whole Asus Zenfone 2 Firmware from the Official Asus support website and follow either these two steps:
3.1 Tools Required:
Asus USB Drivers
ADB installed on your PC/Laptop
Asus Zenfone 2 Firmware from the Official Asus support website
3.2 Flashing stock Asus Zenfone 2:
Method 1:
Turn off your Zenfone 2
Go to recovery mode
Select apply update from ADB
Connect your zenfone 2 with USB cable to your PC/laptop
Open command prompt in Windows (in the same folder where ADB is located)
Check connection by typing adb devices in the command prompt.. If connection successful there will be a list of Zenfone 2 device.
Type
Code:
adb sideload file.zip (where file.zip is the file name of the Asus firmware)
Wait until the process is complete
Method 2:
Copy Zenfone 2 Firmware to the SD card
Enter Recovery mode
Select Update via SD card
Select firmware

Some modules have been known to cause issues, there is a thread with a list of known mods that are safe to use in Q&A I believe...

Yes, with original image I mean the stock system image from the stock rom.
I'll try method 1 but I have a question before:
Since I'm able to boot the phone into boot mode (where it receives adb commands) but I'm not able to boot it into recovery mode (it tries to load something and then stops with error)....do you know if it is the same to send adb commands in boot mode instead that in recovery mode (and I refer in particular to the command: "adb sideload stockasusfw.zip")?
Thank you guys

hmm.. i don't see the point to flash original system image if you want again to install Xposed.
Just reflash system.img preroot and install again your Xposed. That's all. (i've done that many times after trying some modules in Xposed getting me in bootloop)
Go in fastboot mode (power + volume UP) and fastboot flash system system.img and you're good to go to install again your xposed framework.
Preroot image is the same as the originale, but with SuperSu in addition.

It's because prerooted image doesn't allow OTA updates.
However thanks, as I've said before this is my first bootloop and I was a little in panic.
Now that everything is clear I'm going to download and flash the system image.
In boot mode
Code:
fastboot flash system system.img
and it said something similar to this
Code:
target reported max download size of 518205818 bytes.
Invalid sparse file format at header magi fastboot
As I've said in a previous post, the phone did not enter into recovery mode because it got stucked on the "dead" robot. Now, don't know what it happens but after some minutes of "dead" robot, while I was surfing the net looking for solutions, it has finally loaded the recovery mode and from apply update from ADB I've tried
Code:
adb sideload blablabla.zip
the result was
Code:
r: device not found
After that...since I were into recovery mod, I've tried a wipe/factory reset and unexpectedly, the simplest thing has worked! I've got my phone back again.
I'm happy thought I don't understand the errors while flashing with adb and don't understand why the phone get at least 5 minutes of "dead" robot before entering into recovery mode...
Thanks for your support and for your patience
Hi everyone,
After I receive one notification for update the system the battery was over and the zenfone 2 didn’t boot anymore. I get into fastboot mode but I cannot access the options for recovery mode (factory reset, install from adb,…). I just have a few lines in the end of the screen:
E:file path:/tmp/last_install
… until
E:file path:/sdcard/MODF_SUPDATE.zip
After that I read lots of information from the internet (I’m not an expert in Android) and I figure out that my zenfone have firmware SKU CN. Then after read how to change CN to WW I install Intel USB Driver for Android Devices and I made the fastboot flash (droidboot.img, recovery.img and boot.img) commands to change recovery mode to WW (Z00A.2.20.40.59) and now I need to install the firmware UL-Z00A-WW-2.20.40.59-user.zip. The problem, as I said before, I don’t have access to Recovery Mode Options to, for example, install new firmware using adb (adb sideload UL-Z00A-WW-2.20.40.59-user.zip) command. Now when I make a normal boot it stops after a little bit of “Installing system update” and showing android symbol.
Anyone could HELP, PLEASE?
Thanks
while installing custom rom cm13 got bootloop and i cant enter in recovery mode and fastboot too. whenever i try to enter the recovery mode by pressing hard button combination the USB logo appears that's all. i m getting mad, i had googled fastboot corrupt issue for zenfone 2 but no luck, got info for other zenfones, please help me guys !
i can give a try by applying same logic but what i need is Asus Flash Tool, OS raw image,Bootloader image
Apparently this worked for someone who had a hardbrick:
http://4pda.ru/forum/index.php?showtopic=657946&st=6720#entry45086204
Use google translate to translate it.
ZE551ML raw image for you: wwf. fshare. vn/file/JRW15D7JT8DX (change wwf to www)
but first, you must use xFSTK Downloader to recover fastboot.
After you can go into fastboot, if you can't flash anything via cmd because of error, use asus flash tool to flash stock. It will make the fastboot correct again.

Thats not the end. If You can enter the fastboot mode then great.
-Download stock boot n recovery for ur Z00LD
-Download ADB Fastboot drivers and install on your pc. (Minimal Adb and fastboot is an easy available tool.).
-put your phone in fastboot mode and connect to pc.
- open minimal Adb fastboot interface( its a command prompt) or if you have installed ADB fastboot drivers then just press SHIFT + RIGHT CLICK (mouse). Will give you an option to open Command promp. Click it. And a terminal will open on that same path.
-type the following commands.
>fastboot devices
>Fastboot flash boot boot.img
>Fastboot flash recovery recovery.img
>Fastboot reboot (before you press enter hold the volume down key so you will enter into recovery)
Thats it you have now your phone with fastboot and recovery and you can further if required install rom from sd card or sideload.
Like the title says I can´t enter to recovery mode.
Asus zenfone 2 ZE551ML (Z00ADB)
I boot the phone y fastboot, select recovery mode with the power button, and it reboots to fastboot again without doing anything.
I think the problem is that I installed CWM and then installed TWRP on top. So I ****ed up the recovery I think. Is there any way to solve this?
Sorry for my english.
Code:
# fastboot flash recovery <twrp-img>
# fastboot boot <twrp-img>
But, are you sure your bootloader is unlocked?
