dear all
Would like to find out if there is a way to revert to Android 9 ?
I use the phone primarily for audio playback and realized that PIE removed the ability to play back native DSD using the internal DAC...
I got the phone used (came with 10) so i cant quite revert in phone.
This is a korean model and i have downloaded the korean PIE rom as well as the usual LGUP, ANdriod ADK tools etc
not much guides to help (am unable to even boot into the recovery menu - though adb reboot recovery results in a "no command" screen)
help appreciated
thanks
I would love to be able to go back to pie on my sprint v50, is there a way?

Hi, I have a rooted chinese Honor 6+ on EMUI 3.0 and I'm trying to upgrade it to Lollipop. Reason is I had problems with the phone and I factory reset it (turns out it was the sd card causing all problems) and now I don't see any Motion Control options at all, it's blank.
Also, I wanted to be able to restore and backup on google as currently mine has an option (screenshot attached) but doesn't really work. I lost all my settings when I reset the phone.
Any ideas on how to flash either Lollipop or flash a rom with all the google stuff and motion control settings properly working? Phone is rooted with CWM recovery.
Anyway to fix this ?
More details:
I unlocked the bootloader and flashed TWRP on H60-L04. Then I put back the stock recovery (from B521 firmware) and installed firmware B524 which skipped some percentage with faild message quickly and rebooted then the build number is updated and all good except the Motion Control options which are blank. Any way to fix this ?
Now I put back the TWRP. Thank you in advance !
I am trying to get my phone back to the original A10.

My phone is running android 10 v2.5, i was updated from v.1.8
I want to return android 9, if i flashed to EDL 1.6 backup then all sensors down.
A also tried rollback SD Card option (on this page https://www.ztedevices.com/de/supports/a2020g-proopen-market/), starts update normally but after a little progress update failed. I think my phone never been updated to v1.9, because didnt find it. I searched the internet and forum, is there 1.9 version package i didn't find. How i return to android 9 with sensors working, anyone help.
I figured out the problem, i always tried update process (to downgrade from 2.5 to 1.9) in recovery, but i learned that this is wrong. Downgrade process have to run inside phone system updates. To fix sensor problem on my phone, i followed this steps;
1) First lock bootloader again via fastboot "fastboot flashing lock" command (i think this is only works android 9, my sensors still down)
2) Update to Android 10 via SD card method (my sensors working again)
3) Downloaded the rollback package (2.5 to 1.9 or what you want) and unzip it to root directory in SD card as update.zip,
4) Go to Settings -> System -> System Update, then you will now see the downgrade option, then start the process,
After this steps my phone starts on android 9 and all sensors (brighness, proximity etc) working again.
@erturkmen is your phone A2020G or A2020U (US Version)? I am looking for rollback package for A2020U but could not find it anywhere on zte site.

Hi there, my phone A2020G, i download Roms from this page,
Axon 10 Pro(Open market) – ZTE Deutschland
Hello.
I have a Galaxy S4 (SGH-M919) running on android 4.4.4. (I can give you more details if needed).
I need to install an application (EHTERAZ) which is a Qatari government application that only works on android version 6 and up (or IOS 13.5 and up).
Q: Is there a way to make the application work on my 4.4.4 android ?
Q: if not, how can I safely and easily upgrade my android to a newer version? (can you give me a full tutorial or video link)
Q: how to choose an android version that is most suited for my S4 that won't make it too slow or drain the battery too fast ?
Q: will I loose my files during this process ?
Thank you so much for your help, I really appreciate it.
It's the app developer who defines what Android version at minimum is required to run the app.
Upgrading Android requires phone's bootloader gets unlocked ( you lose all your data when doing this ), then a Custom Recovery ( what must be at 100% suitable to the phone ) gets flashed and finally via this Custom Rrcovery a Custom ROM ( what must be at 100% suitable to the phone ) gets flashed.
Hint: Add Galaxy S4 (SGH-M919 to front of this thread's title thus mainly owners of such a phone get addressed.

thank you for your reply jwoegerbauer. I'm not familiar with the terms you used (bootloader, flash, rom) so I'm not able to perform this by myself. Is there any tutorial or video you suggest I follow?
Greetings,
I succeeded in installing android 6 on my S4 and I made the application work fine.
I first installed twrp (twrp-2.8.7.0-jfltetmo.img) using Odin on my PC. I used twrp to wipe my stock system and to install the custom rom (cm-13.0-20161218-NIGHTLY-jfltetmo), in addition to Gapps (arm-6.0-pico).
As simple as that.
The latest twrp and the latest LineageOS that are (allegedly) compatible with my phone and listed in their official websites don't work on my phone, so I had to find older versions to make this happen.
Just read the news https://www.xda-developers.com/android-12l-developer-preview-1-lenovo-p12-pro/
It looks like it's still on early stage but here is the link for instructions and download:

WORD OF WARNING!!
DO NOT USE THE LENOVO SMART RECOVERY ON THE CHINESE XIAOXIN VARIENT. If you flash the P12 firmware to the XIOAXIN Variant you will be stuck in the boot loader with no access to Recovery or ADB.
I actually did use the Lenovo RSA (Recovery and Smart Assistant) on my Xiaoxin variant trying to get it to something more English-based. Didn't work w/ what RSA downloaded which was TB_Q706F_USR_S211043_2111300010_Q00243_ROW which showed up recently. Flash happened w/o problems but upon reboot it was not happy and said H/W was incompatible and then powered off. I got it back into fastboot and was about to reflash 12L.
I was able to get into recovery and my Linux laptop was able to push 12L to it even though adb said device was unauthorized. Maybe that was because I had used it on that laptop before? Idk, I just used recovery to go into fastboot mode and then all the fastboot flash/erase commands worked fine.

That's great news at least you're tablet isn't useless?!
I believe they may be releasing the final updated for android 12L via ota. (there is a post on the Lenovo forums). If you're lucky this may be a back door to an eventual better rom than the Chinese junk. To clarify it's not the fault of the language that is the issue with the Chinese rom it's the problems with the security app, lack of open CL, broken sound in key apps (JustPlayer) and missing DTS codec which is present on the 2021 Pad Pro 11"
