[GUIDE] Downgrade Zenfone 2 Laser to any official firmware

I have discovered multiple ways of downgrading ZenFone 2 Laser out of which two methods proved out to be easy and reliable. Both methods have been tested and are working.
Method 2 doesn't require root while method 1 needs root access.
Pre-requisite: Stock firmware zip file. You can find download links from index thread for all variants.
WHILE THIS GUIDE HAS VERY LESS CHANCES OF MESSING UP YOUR DEVICE, HUMAN ERROR CAN ANYWAY HARM THE DEVICE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO ANY DEVICE. YOU ARE DOING THIS AT YOUR OWN RISK
METHOD 1: Requires ROOT-
Short instruction:
Some users say you can downgrade by renaming the OTA zip to correspond to a higher version but that will NEVER work because the update script has this line
(!less_than_int(1457089250, getprop("ro.build.date.utc"))) || abort("Can't install this package (Fri Mar 4 19:00:50 CST 2016) over newer build (" + getprop("ro.build.date") + ").");

The recovery reads ro.buid.date.utc value from buid.prop. If the value is less than the value in updater-script (like the value highligted in above quote) any recovery will not flash it, neither stock nor custom. Just increaase the value of ro.build.date.utc (in build.prop) to any value higher than the value in updater-script and then flash the zip via recovery.
Detailed Instructions:
1. Open updater-script from the firmware zip. It will be found in /META-INF/com/google/android inside the .zip
2. look at the first line (!less_than_int(1457089250, getprop("ro.bui....
3. The value 1457089250 is taken as an example, your updater-script may have a different value. Keep a note of this value.
4. Install any root file manager like ES file explorer (if you dont have already)
5. Goto /system (the system folder) using the root file manager. Grant root access if prompted
6. Open buid.prop file as text and look for the line "ro.build.date.utc=1446585430"
1446585430 is taken as example, your phone will have a different value.
7. Now increase this value in build.prop to any number greater than the value you noted from updater-script
for example, if my updater-script has 1457089250 this value and buil.prop has 1446585430 this value, I will simply change the value in build.prop to 1546585430 or 1448585430 or 1457089251. Any number greater than 1457089250 will work in my case.
8. Now reboot to recovery (vol down + power)
9. Select "apply update from external sd card" select your firmware zip file, and then select yes to flash. It will take 5-10 min
10. (optional but recommended) Wipe factory/data . If you don't do this, you will see the annoying "Android is upgrading.." screen which takes around 30-40 mins to reach home screen.
Method 2: Without root, requires computer
Short instructions:
As I mentioned earlier, recovery reads "ro.build.date.utc" But you can bypass this check by erasing system partition.
Just do
Code:
fastboot erase system
from fastboot mode and then flash the zip from recovery
Detailed Instructions:
1. Install Asus drivers to your computer. (link in index thread)
2. Download adb_fastboot.zip and extract its contents
3. Reboot your phone to 'bootloader mode'. To do this turn of your phone completely. Hold "volume down Up" button and then press and hold power button. Release power button after Asus logo appears and then release volume down button. Your phone is now in bootloader mode.
4. Connect your phone to pc via a reliable usb cable. Look at your phone screen. It should display "Fastboot mode!"
5. Now go to the folder where you have extracted all the files. Holding down shift key, Right click on any point on white screen. Then click on 'open command window here' from the menu that appears. Command Prompt will open now
6. On command prompt type
Code:
fastboot devices
and hit enter
and check if it is detecting your device.
7. Then type
Code:
fastboot erase system
(this will erase your current OS, you are warned!)
8. After it is done type
Code:
fastboot oem reboot-recovery
to boot into recovery mode
9. Select "apply update from external sd card" select your firmware zip file, and then select yes to flash. It will take 5-10 min
10. (optional but recommended) Wipe factory/data . If you don't do this, you will see the annoying "Android is upgrading.." screen which takes around 30-40 mins to reach home screen.

Successfully downgraded to 1.16.40.763 from 1.17.40.1234 without root
Thanks!

"Failed to mount /asdf" error is harmless you will get that error even on latest twrp. You can ignore the error and use the MM stock recovery like normal. Recovery will do its job it can format, install updates, clear cache and everything, you just need to ignore that /asdf error
But you can use any stock recovery from any firmware version lower than or equal to your current firmware version. Drawbacks: You cannot apply update to MM OTAs if your recovery version doesn't match the current firmware version.
Going back to stock 1.13 is a bad idea. I would recommend you to stay on MM since it has many performance improvements.
But still if you want to go back to lollipop, consider downgrading to the last lollipop update i.e. v1.17.40.1531

I got a 412 mb ota update some days before. I downloaded it. Apply it for proceed. Then it start checking system as usual phone restarted. But update did not happened. Instead this same error show up. Then i can only reboot system. Got an update failed message.since that when i check for updates iam not even getting any. May be it will be solved by a factory reset .but even if i get an ota. The update wont proceed .because the recovery wont allow me to do that
And also that wipe cache partition also results the same error .so without solving this error i cant update to the latest MM too :/ .

In my experience, the most reliable method is to
extract the recovery from the version of stock ROM you want to upgrade or downgrade to
Flash that recovery with fastboot
Wipe /system in fastboot
Reboot to recovery and update with the stock ROM .zip
Or
Even easier, use Sziraqui's fastboot ready .IMG files and just flash them via fastboot.:good:

where can i find the recovery file in Stock rom

The recovery is included in the stock ROM zip file. Extract the zip and you will find it inside.
Presumably if you want to flash the stock ROM you have already downloaded it?

Can you detaily explain that fastboot method as it is for flashing the lolipop recovery for downgrading to 1.13.
Iam a beginner in android. This is my first android phone.

I found out that recovery for each firmware is available here. You should use a desktop browser to use this website.

Thank you.
Can ZE551KL use the recovery.img from ZE550KL? My ZE551KL has the extra 1700(AWS) band.

Please where are you guys downloading your stock rom from?
The stock zip is NOT flash-able like a custom ROM .zip. That's not how it works. If the Roms you have are custom recovery flash-able, they are not the OEM rom, they have been modified.
All the Roms I have come with a recovery.img file...
Then again if I have to explain how to use fast boot to flash the recovery, there is a good chance you shouldn't be messing around with fast boot.......

no it cannot. Do not try it

Weird ..... I can find recovery.img

Can anyone explain me detail. How to flash recovery only. My bootloader is not unlocked. Someone said that i need to unlock bootloader to flash the stock recovery

You don't need to unlock bootloader for flashing stock recovery that you downloaded from the above mega drive.
To flash the recovery.img (or any .img) You need to have Adb and fastboot files in your pc as well as Asus Zenfone drivers installed
All info and downloads for adb and fastboot can be found here
Search and download Asus ZenFone 2 laser drivers.
Once you have your pc setup with these tools,
With Administrator priveleges, locate the folder where adb.exe and fastboot.exe files are present. Hold down shift key and right click on that folder and select "open command window here". Then reboot your phone to fastboot mode [power off, hold vol up +power, release power when logo appears]
Connect your device to pc.
Type the following command on cmd
Code:
fastboot devices
Output should be something like this
Code:
FCAHSJSJJAKAK fastboot
This command will check if your device is connected or not
If output is blank, device is not being detected.
To flash recovery.img, copy the recovery.img file to the same folder where fastboot.exe exists and then type
Code:
fastboot flash recovery recovery.img
Output is easy to understand, if it says [OKAY] then flashing succeeded

Tried downgrading ze551kl by fastboot erase system then installing .zip from Asus website (via sdcard). All of the Asus updates except the earliest fail with 'fota return code 403'.
1.14.40.550 installs ok but then boots (gets as far as displaying the wallpaper), gives an error message in german (looks like 'android media process stopped') and goes into boot loop. Anyone seen this before?
Also, any way to build a recovery.img from the Asus update files?

invalid boot image whenever i flashed stock recovery,any one know why ?
What i do is flash the stock recovery and flash relock bootloader.

I think OP needs a small correction to enter into FASTBOOT you need to press volume up and power instead of volume down and power buttons

Bricked p10, need help.

So I have a p10, and decided to see what i could do with it. Having little experience, I managed to get somewhere. Unlocked the bootloader, got twrp, installed it with the command fastboot flash recovery recovery.img and got:
target reported max download size of 471859200 bytes
sending 'recovery' (32034 KB)...
OKAY [ 1.012s]
writing 'recovery'...
OKAY [ 0.200s]
finished. total time: 1.222s
WOOT! Awesome! No problems! Then I issued: fastboot boot recovery.img
And got
downloading 'boot.img'...
OKAY [ 1.020s]
booting...
FAILED (remote: Command not allowed)
finished. total time: 1.030s
WTF?!
So after a bit, I misread and flashed boot.img with: fastboot flash boot boot.img
I guess I flashed the wrong image. I dunno. But now it boots into the screen that tells me "Your device is unlocked and can'r be trusted" tells me its booting, reboots, goes to the same screen again, says its rebooting again, then brings me to Huawei eRecovery. I connect to my wifi network, telling it to download the latest version and recover, and it says "getting package info failed" So I ma stuck with a device that won't boot.
Oh yes, and down volume and power don't bring me to fastboot anymore.
Begging for help here please.

Do the whole rebranding to unbrick, not sure if you flashed wrong image on boot.
Advice: When flashing recovery boot it by powering off and using key combo. Or adb command. Not from fastboot as IMG.

I did a google search on rebranding to unbrick, and found a guide on the 9. So I assume its similar. It first tests me to boot into twrp. I can't. Twrp never got installed. The next step is to get the offical firmware and put it on the SD card. I can't find it. I am in Canada, and can't find any firmware for canada, nevermind anything north american. It is however possible I have found the wrong guide, as I don't really know what I am doing. As a complete noob, links to guides would be nice when possible and available when making recommendations.

The guide is the same for Mate 9/pro and P10/plus
Original: https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
Explained as easy as posible:
Unlock bootloader (check again that boot loader is unlocked)
Download Update ZIP. I suggest rebrand to VTR-L29 C432 !
A. Get ROM update link through hwmt.ru. Click "filelist.xml". ---> http://hwmt.ru/hwmtsite/firmware-database/?firmware_model=VTR-L29&firmware_page=0
B. Observe "update.zip" size, choose more than 1GB file size FULL OTA . Example VTR-L29C432B164 filelist Link, all three update files and path are in the filelist.xml content.
update.zip: Change URL last "filelist.xml" to "update.zip" download file.
update_data_public.zip: Change URL last "filelist.xml" to "public/update_data_full_public.zip" download file, and rename it to "update_data_public.zip"
update_all_hw.zip: Change URL last "filelist.xml" to "hw/spcseas/update_full_hw_spcseas.zip" download file, and rename it to "update_all_hw.zip" Where spcseas is the model of the file you are downoloading.
Update Package (Download these at original post)
Base: HWOTA_2017050101_Base.zip
OS: Windows -> HWOTA_2017050101_Windows.zip
Model: P10 -> HWOTA_2017050201_VTR.zip [Thanks to @crucky verify]
Put HWOTA on pc desktop and on your external SD card (if you have one, otherwise update process will took a couple of minutes more)
Those 3 downloaded files goes on UPDATE dir, inside HWOTA
Run batch file "update.bat" for same model update or rebrand with/without sdcard.
Select rebrand chose what model is desired (Must be the same as the update package)
Always check the process continues (Sometimes it stucks on twrp or need reconnect to PC)
Once finished Factory default reset will start
Do the process twice! select "Same model update" on the second time.
After update successfully, device might be locked again.

okay, i know you are trying to be helpful, but I just can't follow it...
You said "Download Update ZIP. I suggest rebrand to VTR-L29 C432 !" Which one of them? Is the B just a build number, and I should get the latest? please remember, you are talking to a noob.
You talk about 3 files, update.zip, update_data_public.zip and update_all_hw.zip Do I need them all? If so the last one, where I change filelist.xml to all /cn/update_full_all_cn.zip doesn't work. See the following link http://update.hicloud.com:8180/TDS/.../v92067/f2/full/all/cn/update_full_all_cn.zip
Also, rename the file, "Where spcseas is the model of the file you are downoloading" Huh? I know I have to replace the word spcseas with something, but with that?
Now it says to run update.bat Whats the point? I have not been directed to plug the phone into the computer, and even if I did, the computer won't recognize it because I can't get it into any mode... Where do I put these files? They all go in the same directory? I just can't follow this guide as much as I try..
THERE IS GOOD NEWS HOWEVER!
I have been able to get it into TWRP! This means I can get into fastboot, which means I can re-flash the correct boot.img, IF I can get my hands on it (and assuming that's the actual issue It likely is. It was working until I flashed this other boot.img file.). So if I can get direction on how to get it, I should be okay. Double triple and quadruple bonus points for just providing me a direct link to the boot.img file to use without having to play around trying to follow guides I can't seem to understand.
UPDATE!!
Now although I can get into TWRP, its hit and miss, but I can get there eventually, it will no longer boot into fastboot/recovery. When I click reboot, and choose bootloader in TWRP, it just freezes..
This is getting frustrating. Apparently getting into the bootloader is hit and miss, but i can do it.

Search for Huawei update extractor in order to get BOOT.IMG from update.app (inside update zip) I could upload one myself, but I'm not at home right now.
TWRP doesn't support reboot atm. You must power off completly. To boot to recovery press power on and vol + until huawei logo appears, then relase power. It should boot to recovery TWRP in this case.
For boot bootloader you press vol - when you are connecting usb cable to PC.

For boot bootloader you press vol - when you are connecting usb cable to PC.

Thats good to know. I was getting TWRP more often when I did it from off. What was happening was I would holds power and volume up, release power when the logo appeared, and MOST of the time I would boot into TWRP. Sometimes it would just reboot, I would continue to hold up, and it would either reboot, or boot into TWRP. Occasionally I would get the recovery that came with the phone ?!?!
In any event, I managed to get into TWRP, boot into recovery, extract the boot.img, flash it... AND IT WORKED! Phone booted!
So after all this, I backed up EVERYTHING I could using TWRP. The Boot partition, System partition, EVERYTHING! It kept failing on the Data partition, but from my research that wasn't that important anyway. I then installed SuperRoot_noverity_nocrypt.zip, rebooted, installed phh's SuperUser, installed Root Checker, and finally, I have root!!
Thank you so much for the help. About to go "thank clicking" for all the help you provided.

You have PRA-LA1 so L01 and L21 probably will not work, find LA1 first.
Installation Instructions
Take a full backup of your important data before proceeding.
Download “update.zip” and “update_full_PRA-LA1_hw_meafnaf.zip”.
Connect your device to your computer via USB and create a new folder “dload” in the external microSD card or internal memory.
Now unzip the “update.zip” package and copy the extracted UPDATE.APP file to the new dload folder you created in the previous step.
Now with phone off press vol +, vol - and power at same time and release on boot. If the installation succeeds proceed to the next step otherwise try installing this update with TWRP.
Once your phone starts up, replace the UPDATE.APP package from dload folder with UPDATE.APP package extracted from the cust package (“update_full_PRA-LA1_hw_meafnaf.zip”).
Now install this package by repeating steps above.
TWRP Method
This method requires your phone to have a custom recovery like TWRP. Simply download both the packages from above and copy them to your device. Now reboot into TWRP mode, take a full backup, and then install both packages (update.zip first). Reboot your phone normally upon completion.
I hope this helps.

Problem with flashing stock rom (EVA-L09)

hello, yesterday i've unlocked my bootloader but since i had some problems flashing roms and installing root, i've decided to go back so i have locked my bootloader but i forgot to write down my code so i'm pretty much lost because I can't boot into emui or anything. i only have emui erecovery but i cant press anything because i'm guessing the touch doesn't work anymore?
i went into fastboot and tried to flash boot,recovery and system but i had no luck because i was getting this error:
fastboot flash boot BOOT.img
target reported max download size of 471859200 bytes
sending 'boot' (14992 KB)...
OKAY [ 0.350s]
writing 'boot'...
FAILED (remote: Command not allowed)
finished. total time: 0.361s
I think this has to do with the bootloader locked?
but since i cant boot into anything and cant even touch anything in recovery, i feel like im out of luck. which i don't hope so i thank you guys in advance if someone can help me
have a good day

Get a micro SD card and download this zip file https://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818 extract the zip file and should see a folder called dload put that folder onto your micro SD card put the micro SD card back into your phone. Hold down the volume up, volume down and power button all at the some time until about 10-15 seconds you're device should install the stock firmware via the Huawei e-recovery. Sometimes the installation will fail at 99% but I assure you that it is completely installed just reboot your device and you should be booted into the stock firmware.

tried that but i get
software install failed!
get help from etc etc
reboot system now

This might be a bit hard to explain, on the SD card rename the dload folder to dload1 and a make a new folder called dload go onto to dload1 then go into EU and put the EU update file into the dload folder flash by holding down the three power buttons this will lock your bootloader and restore to stock recovery after that go onto your SD card and delete (or move) your EU update file from your dload folder go into your dload1 folder and get the UPDATE.APP file and move it to the dload folder (just the UPDATE.APP file nothing else) flash with the 3 button method and that should work.

Look at my description:
Use the Rollback_Package_EVA-L09_to_EMUI4.1_Android6.0_C900B300.zip to rollback your phone there are instructions inside the zip file.
After this use the B136_full_update.zip the same way.

Restore original firmware

P9 EVA-L09. I am trying to get original firmware.
The phone was rooted. I relock the bootloader using adb. After that phone has stuck in Huawei eRecovery and can't download firmware.
I use the dload method to perform upgrade. I have downloaded few months ago two zip files.
First copy only the UPDATE.APP (~2GB) file to dload folder on sdcard. Then phone start working. After that from the other zip replace, put the all files
in dload folder. Upgrading was successful, but few apps are missing - camera, contacts and etc -> example ?
Trying this image says: installing updates fails after 10-15%.
Can you suggest me how to fix it or may another image to use?
Thanks in advance !

Did you restore stock ROM (by eg HWOTA) before relocking - because (re)locking invokes Factory reset. There was also another report of similar brick bexause of relocking with rooted or custom ROM.

No I am not. It was stock rom which I rooted.
I am trying several update.app but when processi is complete always something wrong. No all apps installed or keyboard missing and etc.
Can you suggest me what and how to try to install?
I found this link with images.
I am downloading both B136. First I have to copy UPDATE.APP to dload folder on sdcard from update.zip. Then delete update.app from dload
and extract all from B360_update_data_full_hw_eu.zip to dload folder and again perform upgrade (turn off the phone, then holding vol up + vol down + power key
until logo display)
Is that correct?
