You cant sideload a zip file. You need to sideload the pre-rooted image then update to go back to stock...

How to install OTA updates on rooted desire 816

Please help me am not able to install update ,
Yesterday I downloaded new update 2.34.720.2 when am trying to install it's not happening
I need to stock recovery? For update
Then how to get stock recovery ?
Please help me
Same here someone pls help ??
Check the general forum for how too guides. You might find something for your device. Otherwise you can download but delay installing the OTA. Hook up USB cable to PC then copy the ota zip file from the Download directory on the phone. Extract the files from the ota zip. You'll find a firmware directory with a firmware.zip file. Extract that too. In there you should find a stockpatchrecovery.img you could try flashing that before you re-lock boot loader. If you ran a lot of mods tot he stock Lollipop you might have to run the ruu.exe for your model before trying the patch.

Am updated new software
Download OTA update and copy into your laptop, Then extract ota zip file
In the extracted file you will find firmware.zip
Extract firmware.zip then goto firmware folder u will find recovery.img
Copy recovery.img into your fastboot folder(when you rooting your phone you used fastboot folder)
In your phone check usb debugging on then switch off mobile
Press power+ volume down buttons
Select fastboot
Connect to your pc
Open fastboot folder then press swift and right button on mouse
Select open cmd here
Then type = fastboot flash recovery recovery.img
After that reboot your phone then update now .
If anything goes wrong am not responsible
I tried this method successfully.
For Smooth process you need to go back to official stock ROM.
With this you can unroot your device also.

Problem when going from CN > WW firmware

hi,
I got my zenfone 2 in CN firmware. I tried to convert it to ww using this ( http://forum.xda-developers.com/zenfone2/help/how-to-upgrade-cn-version-to-ww-t3101556 ) method. Downloaded the latest UL-Z00A-WW-2.20.40.139-user firmware from asus website. Flashed boot.img recovery.img droidboot.img for 2.20.40.139 from here ( https://mega.co.nz/#F!k4MHiAgL!dVuOKeH3eokcwPSNI79ffw ). Moved "UL-Z00A-WW-2.20.40.139-user.zip" to root folder of memory. Got no system update prompt. Then changed the name to "UL-Z00A-CN-2.20.40.139-user.zip" and rebooted. This time got the prompt. But after automatically tying to flash the firmware, recovery shows error after 20%. Help please !
Edit: also tried to flash through adb sideload. But ADB cant find device in recovery but can find in fastboot mode

redownload the files
Re download, in fsdtboot check that your drivers installed on PC, sometimes adb would not see the phone but would still flash. Just try sideload method with adb, if it errors out it will show you actual reason. My bet is on the sku still being CN. Also try the 93 version of full 1.1 gig WW firmware. It worked well for me.
Thanks everyone ! Turns out the file i downloaded was corrupted. Downloaded the firmware again and worked !

Screwed up--stuck in boot animation

Hi--
I could use some help. I have the rooted stock and installed a new boot animation. Now the phone will not boot. It stays in the boot animation. It does not bootloop. It booted fine prior to the bootanimation.zip replacement. I cannot ADB into the phone to delete the zip but I do have fastboot. Tried to install TWRP to flash a new bootanimation.zip to fix, but TRWP install fails (permission denied). I completed the Asus bootloader unlock to get root.
What can I do?
Thanks--
do you unlock bootloader ?
try to fastboot
use adb command "fastboot flash recovery name.img" to install twrp
Thanks for the reply. I do have a fastboot connection, but it errors when trying to flash recovery:
writing 'recovery'...
FAILED (remote: Permission Denied)
finished. total time: 0.906s
I know the BL is unlocked as that's how I rooted it an hour before this happened.
Thanks--

USB debugging should be active but I cannot verify since it will not boot. Yes, I used the Asus app to unlock the BL. How would doing a Factory Reset help if the error is in system, not data?

Thanks. Couple of questions. Where do I adb sideload from? When the phone is in stock recovery or BL/fastboot screen? I've tried to ADB from BL/fastboot screen and I don't have a connection.
Also--which stock ROM do I use? The WW version as I only see a JP, CN, TW and CUCC versions...no US specific version. WW is the right ROM for US?
Thanks again--

put your phone in recovery then select adb option (if you dont know how. google how to get in recovery zenphone 2)
put the stock rom in folder adb
then you can use this command
you can check your version on fastboot screen
i think US = WW

if you wanna do sideload first you need Asus Zf 2 firmware --> http://www.asus.com/Phone/ZenFone_2_ZE551ML/HelpDesk_Download/ download the same firmware installed in your phone (settings-->about phone--> see the build number--> that's your firmware) or you can see it when you on recovery mode (ww=worldwide, so US is ww).
download fastboot_adb (1.0.32) --> https://www.mediafire.com/folder/w70w7r1a65840/Zenfone_2 and the unzip the file, copy/put Asus Zf 2 firmware that you have download into fastboot_adb (1.0.32) folder ( you can rename Asus Zf 2 firmware with "file" name or you can leave it that way)
go to recovery mode--> select apply update --> select apply update from adb
open fastboot_adb(1.0.32) folder --> hold shift + right click --> select open command windows here --> type adb devices
--> type adb sideload file.zip ( or you can just drag Asus Zf 2 firmware ) --> wait till it finish flashing --> when it done reboot
Thanks for all the help here. I was finally able to side load the ASUS ROM and I'm back in business. All due to a bad Boot Animation ZIP!!??!!
I had trouble because adb would not do the push/install anything due to a bug in HTC Sync, which I still had installed from an old phone. Apparently, they have a custom DLL/library that breaks adb. Once I got rid of Sync, I was able to push the ROM a over and was back in business. Thanks again for the help.

Type fastboot devices and it should show your device serial number. As long as that appears you will be able to sideload the latest version

are you on recovery mode? using stock recovery or custom recovery? custom recovery will never work when flashing through adb sideload, i'm flashing latest firmware through sideload just now
Actually i was in system recovery earlier. İ did something. I tried load twrp (teamwin) and i did. It opened but and then i reboot the bootloader and chose recovery but it didn't start recovery it just restarted the bootloader. So i have just fastboot mod now and my computer sees my phone when i type fastboot devices. Can you say one by one what should i do

you should on recovery mode to do sideload, also in my experience i never succeed apply update from adb using teamwin, that's why i always go back to stock recovery if i want to update through adb sideload, but to get stock recovery you have to go back to stock Rom, you need stock Rom and fastboot_adb(1.0.32) ( i already give links to get those files in the comment before) download the stock rom (choose 1 for ex: Z00A_WW_2.20.40.139) unzip that file ectract to Z00A_WW_2.20.40.139, you should have the following files: system.img, boot.img, droidboot.img and recovery.img. connect your phone to pc/laptop, open cmd on Z00A_WW_2.20.40.139 folder by press and hold Shift keyboard key+right click (select open command windows here), In the cmd window enter the following command: “adb reboot bootloader”, Next, in the same cmd window, type the following commands (press enter after each line): “fastboot flash fastboot droidboot.img”; “fastboot flash recovery recovery.img”; “fastboot flash boot boot.img”; “fastboot flash system system.img”. (i will provide you a picture when i'm doing that), when done, still on cmd execute the following commands: “fastboot format userdata” and “fastboot format cache”. up to here it's done you can reboot your phone, if you want to update the simple way just copy firmware file you want to update to internal storage and remove usb cable it will auto detect an update, but if you want to do update using adb sideload after format cache do not reboot phone just go to recovery mode(by pressing vol button twice), select apply update from adb, on pc open fastboot_adb(1.0.32)_071114_r21 folder, put firmware you want to update in this folder (ie : UL-Z00A-WW-2.20.40.168-user), open cmd on fastboot_adb(1.0.32)_071114_r21 folder by press and hold Shift keyboard key+right click (select open command windows here), In the cmd window enter the following command: "adb devices" it should show you devices no and sideload, in the same cmd window, type the following command: "adb sideload file.zip" wait till it done, when it done reboot your phone.

There was no img file in the link, just cwm zip. So there was nothing to flash, at least nothing in a way that I know of.

You have to unzip the zip file using winrar or any other such software and then copy recover.img file where you have kept the adb drivers
Regards milkyway3
That's what I was trying to say. Unless I downloaded the wrong thing somehow, or my pc has some sort of an issue, there's no img file inside none of the zipped folders.

Sorry for the wrong link
This is the correct link for direct download
https://www.androidfilehost.com/?fid=24591000424964938
Follow these steps:
Download the TWRP recovery image to be installed on your Android.
Enable USB Debugging under Developer Options.
Install ADB and Fastboot utility on your PC via
https://devs-lab.com/download-lenovo-usb-drivers-adb.html
(extract the above rar and install exe file)
Go to the directory where you have downloaded the TWRP image file and then open the command console or termianl on this directory on your PC. To open a command window on Windows OS in the current directory, press shift + Right Click anywhere on Windows explorer, or some folder. Then on the menu opened, just press the “w” key on the keyboard or select “Open command window here” to open a command window.
Now connect your Android to the PC using a USB cable.
Enter the following command on the command window opened:
adb reboot bootloader
to put your Android into bootloader mode where you can flash/install the TWRP recovery.
If your Android device asks permission such as “Allow USB debugging” then just tap on OK to proceed.
Now when your Android is on the bootloader mode just execute the following command on the console:
fastboot flash recovery twrp-3.0.x.x-xxx.img
While executing this command make sure to replace the twrp-3.0.x.x-xxx.img with the actual file name of the TWRP that you have downloaded for your Android.
Wait for the TWRP to be flashed. Once it is done execute the following command:
fastboot reboot
on the command console and done, your Android is now installed with TWRP recovery.
Hope this helps you out
Regards milkyway3
I'll do it as soon as I can. Thanks again.

Hi to everyone!
I just bought a Lenovo Vibe P1 version P1C72 ( 3gb Ram and 16GB memory) from China and it came with Android 6.0.1 installed, VIBE UI.
Unfortunately there are o lot of bugs in this version, and i want to downgrade my phone to Android 5.1.
Could somebody tell me if i can do that by following the method from androidMTK.com, using QcomDloader Tool and lenovo P1a42 stock rom?
Or there is another way to downgrade my phone, because that seller guy from China told me there is no way to go back to Android 5.1 ?
Thanks in advance !

The nfc will not work with 01a42 lollipop, and i dont have chinese 5.1 sorry. Maybe u can try some good custom rom from the developers
If only NFC is the problem, i don't mind. I'm not using it, anyway.
But the method, using QcomDloader Tool, or another tool, is safe?
I'm not risking to brick my phone?
I'm still thinking to flash my phone using Qfil and put version P1a42_S135_1510131022_Q20248.2_ROW instead of Android 6.0 Marhmallow and get rid of those problems.
Could it be done such downgrade?
also looking to upgrade my p1a42 to nougat rom that is stable no bugs. is there a reason you gave cwm instead of twrp? say we go with cwm are there any rom it will not flash or just about any rom it will handle? i prefer twrp by the way there is one for the p1 but people are having issues flashing it. your advice is truly appreciated.

Link to what you're flashing? I can build a .bat file for you that does all the commands for that firmware zip easily.
It hasn't been tested on a locked BL though... Mine was pseudo locked but the other slot was unlocked so that might be why it flashed just fine
1789-05 is not AT&T hardware XT-1789-4 is AT&T and Tmo hardware it could be your files are for the wrong device i seriously effed mine up trying to root it but i got it to boot again with the nougat update.
here is a link to my drive and the script i have for the moto Z2 force.

you still need your files from a rom site like this one:

i would not roll back as some people have had issues but i was able to flash a at&t rom on my phone and go back with this. just flash oreo back in.
make sure you enabled adb before starting.
well the way it works is you download the rom from the site (yes use the oreo version) then you unzip the rom and copy all the files to your platformtools directory.
next you place the .bat i gave you to the exact same location you just copied the rom files (platformtools directory)
now open a command window from the platformtools location and then enter the following:
adb devices
this should detect the hardware, next.
adb reboot bootloader
this will reboot to the bootloader, and we now switch to fastboot.
fastboot devices
this is the same as the adb command, and confirms the hardware is being detected.
now we are set to double click the .bat file and it will auto run.
if you want you can open the .bat file in edit mode and run each command manually by copy and paste
try this one for the script
