Downgrade to Marshmallow

Hello Friends, I just upgraded my Zenfone 3 ze520kl to Nougat, but i prefer Marshmallow i try from recovery mode to flash Marshmallow, it shows error and the installation aborted. Can any one help . Thanks.

What error does it show?

Error with some numbers follows by 'install aborted'. I unable remember the error numbers. I did three times all the time with same remark.Thanks.

That's not very helpful. Can you try it again and tell us exactly what it says?

Hi,
I downgraded a few days ago, here's an overview of the steps.
WARNING, this requires a factory reset so you will lose the data on the phone, so make sure you have backups before you proceed. You do this at your own risk and I am not responsible for any damages.
I assume you have adb / drivers all configured and know to how use them.
1) download firmware file http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE520KL/UL-ASUS_Z017D_1-WW-13.20.10.152-user.zip and save to SD card / insert card in phone.
2) download recovery and boot img files for Z017D_WW_13.20.10.152
- https://mega.nz/#F!ok0V0RIA!5WKtHe98opzjVI3NPbM7Ww
- under the folder Z017D_WW_13.20.10.152
3) Go to fastboot mode (power + vol up)
- flash recovery.img (command: fastboot flash recovery recovery.img)
- flash boot.img (command: fastboot flash boot boot.img)
4) reboot to recovery (power + vol down)
5) install update form micro sd card.
set the file UL-ASUS_Z017D_1-WW-13.20.10.152-user.zip that you saved earlier
6) wipe cache
7) factory reset
If you don't do a factory reset and reboot, Android pretty much crashes on multiple processes on start up, it is unusable.
Regards,
TK

Warning- No file-contexts. This package is for "ww-phone" devices, this is a E:error in /side load/ package.zip (status 7) Installation aborted.

Same thing happened to me as well. I just went ahead to flash the RAW file (http://www.asus-zenfone.com/2016/12/asus-zenfone-3-raw-firmware-and-asus.html) and updated the software to the latest marshmallow update, followed by a factory reset.

If we Downgrade
Then we get update in future yes or no??
Sorry for bad English??

Yes.

Hi, thanks for the help. Please answer this:
Do I need to use Recovery and Boot.img the same version of ROM? Why?
Why do I need to install Boot.img?

Huawei P8 Bootloop

Hi guys!
I have an issue here with the Huawei P8. I wanted to go back to stock from ARROW ROM, so
-I used Huawei Extractor to get the stock recovery and flashed it via fastboot adb
-Updated my phone with the 3 button method and put the DLOAD folder into my SD card
-I used B394 to get the recovery img and to update as well (it was ~1,6Gb)
The update started and everything worked fine, the phone said everything is fine but my phone stuck in bootloop. I mean it doesn't restart or anything but all I can see is the Huawei logo.
What should I do? Any tips how to fix this?

First try getting into Recovery mode & doing a factory reset & cache wipe.
If that doesn't work, try with a stock rom that's one prior to what you had before installing Arrow - like in this thread & follow the steps there (i.e. you first need to flash boot, system & recovery .img files extracted from the prior rom): [GUIDE] How to unbrick HUAWEI P8 when failed to update and ends in bootloop
If you cannot find where to download the prior stock rom, ask for help - someone may be able to provide a link that works. Tell us your phone's full, original model number (GRA-????), the region rom you need (e.g. C432 would be European) & the version B???.

I need the original boot.img for the very first firmware on asus zenfone 3 520kl.

I have twrp flashed on my phone, and so cant get the oreo update. The phone had been stuck in the bootloop recently, and the guy at the service centre flashed the first available version of the firmware, but how he did it without removing the custom recovery, i dunno. So now i need the boot.img for this firmware: (WW_Phone-13.16.5.33). Thanks in advance.

It says the stock firmware is for nougat, i myself am currently running marshmallow. I had tried to flash nougat through the custom recovery, ( when the thing was stuck in a bootloop) and it said something like only versions upto *some serial no.* can be updated.
Anyway, thanks for the links, will try it.:good:

Hello, I own the ZE552KL (Z012), but when I saw your question I was able to find a link containing what you need for your model. Take a look, I did not download but I believe it contains the necessary files.

-save UL-ASUS_Z017D_1-WW-13.16.5.33-user.zip to SD card / insert card in phone.
- under the folder ''boot recovr z017dww13.16.5.33''
2) Go to fastboot mode (power + vol up)
- flash recovery.img (command: fastboot flash recovery recovery.img)
- flash boot.img (command: fastboot flash boot boot.img)
3) reboot to recovery (power + vol down)
4) install update form micro sd card. set the file UL-ASUS_Z017D_1-WW-13.16.5.33-user.zip that you saved earlier

soft bricked my phone

hello!
i have a p9 lite vns-l21c432b380 dual sim
some days ago i contacted huawei to get the bootloader unlock code. after that i unlocked it via fastboot, flashed elite twrp recovery 3.2.1.0. everything working fine til now. i then tried to flash from twrp latest lineageOS release but it doesn't seem to be working as on reboot i get stuck on "you're device is unlocked and it can't be trusted" screen with the options to boot system and erecovery. it just stays there, no sign of lineage os.
i tried to restore at least the stock rom via dload and 3 button method and to flash extracted bits frome the update.app file via fastboot with no success: i always get a "update installation failed" error, with the only option to reboot the phone to nothing
what am i doing wrong?

update: i tried to flash oem info for l21c432 dual sim from twrp, then retried to install via dload and 3 button method. no luck, still "software install failed" and nothing else

OEMINFO: ftp://XDA-Dev:[email protected]/Oeminfo/L21/L21_DS_C432_by_EasySR.zip
FIRMWARE: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66034/f1/full/update.zip

i'll try to flash both via fastboot, since the recovery won't now mount data
thank you

fastboot gives me "command not allowed", flashing via elite twrp 3.1.1 "invalid zip format". what am i missing?

You need to flash oeminfo with TWRP. (Unpack the arhive then copy the oeminfo.img on your phone)
And also , unpack update.zip .
Then make a new folder on sdcard called dload and put update.app there.
Then boot into dload mode and it should work.

i'm not sure of how it worked. now i have TWRP 3.0.2 installed and stock ROM VNS-L31C432B150. some how it changed from l21 to l31.
do you think there's a way i can flash latest lineage os or should i stick to b150? in case how can i do it?
thank you for patience and time

PLZ　HELP ME Mate 9 Pro LON-L29C636 brick

I accidentally wipe Dalvik/Art cache、System、Data and Cache through twrp recently.
Now, my phone shows no OS, so can not boot in system.
I can enter TWRP and fastboot and e-recovery, but I have tried to install UPDATE.zip, it always show error. I can install update_full_LON-L29_hw_spcseas.zip sucessfully though.
Is there anyway to fix my brick mate9 PRO>< PLZ help me
Another problem is that I cant install zip files through install(my phone doesnt have a sd card), the directory always shows encrypted text and wouldnt let me choose. I have tried few recoveries, including TWRP_3.2.1-0_OREO, Rayglobe_Recovery, and twrp-3.1.1-0-hi3660. Some of them cant getin recovery after flashing them, the rest shows encrypted text. Can anyone please save my brick phone?

TWRP doesn't work correctly, since the phone uses encryption.
I'd try downloading the Huawei Multi-tool, then download a full update through it, that fits your phone model. Then (assuming you have access to fastboot) flash the downloaded update through the Multi-tool program.
Basically this:
Huawei Multi-tool > find correct firmware with Huawei firmware finder (it's included in the program) > extract the different parts of the firmware needed, which is displayed on the the unbricking tap, and follow the rest of the instructions displayed there.
