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

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
I have zenfone 2 with a cn recovery on it but says it has a ww build. I keep getting a pop up permission, which is really irrating. If I want to put a development rom on my phone do I have to change the recovery first(cn to ww)? What is the procedure I need to go through to get this phone working properly? I've read the cn to ww threads but the links to builds are old. Which ww build do I start process of changing the cn to ww recovery?
Where do I start...?
Any help would be welcomed
Look at this : http://www.asus.com/zentalk/forum.php?mod=viewthread&tid=14962
I also have a CN version, however I updated my phone to the most recent Chinese Version ( 2.20.40.185) and now whenever I try to execute step Write adb sideload file.zip I get error: protocol fault (no status). However the version I tried it with is not more recent thatn 2.20.40.185 do I have to wait for a new update in order for it to work?

Did you enable developer mode in settings and tick USB debugging?
If not you go to settings>about, find build number in about and click on it until you see developer mode enabled. Go back up one level in settings and you'll see developer settings, turn on and tick box for USB Debugging.
Then go back to and try adb sideload again.
If you want root then the best idea is to go to Shakalaka's pre-rooted rom thread in Android developement and download the version you want, I believe he has 2.20.40.184WW there now, then use fastboot to replace the boot, droidboot, recovery and finally system files. Be VERY careful about copy and paste as there have been people who brick their devices due to overwriting the same partition with all the above files.
To Change CN to WW - Use Fastboot Flashtools
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash fastboot droidboot.img
fastboot flash system system.img
Cheers...
Hello everyone,
I have big problem with my Zenfone 2 ZE551ML. Phone started standard OTA update but something went wrong... So what's the situation?
- firmware: LRX21V.WW-ASUS_Z00A-2.19.40.22_20150627_5104_user
- I can flash using fastboot. I tried to flash dnx, ifwi, fastboot, splashscreen, boot, recovery and system. Flashing process works good but there is no reaction after all. I was flashing phone using files from here: asus.com/zentalk/thread-79657-1-1.html
- I can charge the battery, run fastboot mode, enter ADB Sideload mode, phone is visible in fastboot and adb terminal
- I can run system recovery, wipe data, wipe cache
- Problem is with OS - there is only Asus logo with circle - classic bootloop
- I can't flash new system using ADB Sideload mode - process stops with error when it try to update IFWI (screen from cmd is under this text, phone restarts immediately)
- I can't flash new system using RAW file and Asus Flash Tool - "Flash image failure(FAILED (remote: GPT command failed)"
- I can't fix bootloader using xFSTK - "XFSTK-STATUS--Error Code: 29 - ER25 - Programming /n ER25 - Storage Programming Error /n ER25 - IFWI checksum mismatch FUPH.IFWIChxxSum"
I don't know what to to now. I tried every single tutorial. Everytime there is a problem. I have all drivers, I tried each method few times on two PCs with Windows 7 and 10. I am using USB2.0 port...
Anyone could tell me if its even possible to fix this phone?

I'm right now in 2.20.40.198 (L). I can't perform Recovery Mode functions. Tried Factory Reset, but no use. Tried placing Firmware.zip in root folder. Update is recognized but on restart there is no change. I can enter the boot menu with the dead android, but when choosing Recovery Mode, the device just gets restarted.
Asus Flash tool throws this error " XXXXXXX_frp_request_server_log.txt (error 5: access is denied.)"
The device seems to be in Fastboot Mode. Shows this:
Product_Name - Z00A
Bootloader Version - unknown
IFWI Version - 0094.1069
Serial Number -
Signing -?
Secure_Boot - ?
ADB recognises the device but when entering "adb reboot bootloader" , I am taken to the same Fastboot Mode.
Help appreciated.
Anyone here who can troubleshoot?
Thanks

Hello there,
Did you manage to solve it ? I am in same trouble now and searching for help.
I am in the process of installing LineageOS 18.1 onto a Pixel 3 XL (I have done a Pixel 3 before with no issues). I am following the instructions from lineageos.org (https://wiki.lineageos.org/devices/crosshatch/install). It is specific instruction for the Pixel 3 XL. I have successfully completed the first number of steps but got stuck on the last one noted below:
Unlocking Bootloader (ALL COMPLETE)
enable OEM unlock
connect device to PC
adb reboot bootloader
fastboot devices
fastboot flashing unlock
reboot
re-enable usb debugging
Temporarily Booting a Custom Recovery
download a custom recover (lineage-18.1-20210803-recovery-crosshatch.img) - COMPLETE
connect device to PC - COMPLETE
adb reboot bootloader - COMPLETE
fastboot devices - COMPLETE
fastboot flash boot lineage-18.1-20210803-recover-crosshatch.img - COMPLETE (received msg that sending and writing to boot_a is okay)
reboot into recovery - INCOMPLETE
will not reboot into recovery, stays in fastboot mode
last line on fastboot mode screen says "no valid slot to boot" at one point it also said "error booting boot.img"
Any idea/suggestions on what would be the problem? I did try redoing the fastboot flash boot command an additional time and again it said it sent and wrote ok, however, still unable to reboot into recovery. I did not check the version of android on the phone before i flashed the lineage 18.1 recovery - could that be the problem? Might it be that the phone cannot run LIneage 18.1 because it is on android 10? (which I'm not sure how to check at this point). If this is the problem what would be the best solution - reflash with a lineage 17.1? Or, is there a way at this point to check and upgrade the android on the phone? Perhaps there is another problem entirely.
