Hello everyone,
It is possible to downgrade to Android 8.1 from Android 9 on Samsung A9 ?
I updated it to version 9 and it is very confusing to use as design changes are looking really bad.
If i restore original samsung 8.1 version what program do you recommend for full data backup so i don't loose any data/applications/pictures on my phone ?
Thanks.
Apps are linked to google account, they can be re-downloaded. As for data from the applications you'd afaik need elevated permissions to access that data or a custom recovery. Pictures you should be able to easily back them up to your PC. Generally you can always downgrade but you may be nagged about updating. Also if you had a custom recovery and restored data to an older version, it may or may not cause issues.
I can't give you full insight because the last device I've used relating to samsung was their note/note pro, and the s6. I just thought I'd toss what I do know here.
Hello everyone,
I am trying to run successfully a gps mocking application on my s7 running android 7 .
I have read a guide about this and one of the steps is downgrading google play services. Meaning that I have to deactivate it, it will automatically reset to its original version and then I will install the version that I want (hoping that I find it).
I was wondering if there can be anythihng that could go wrong in this process and brick my phone. Or in case something goes wrong reinstalling the latest version of google play services should be enough? Thanks in advance!
I have a SM-G9300, which is a Chinese dual SIM model of S7, with a Snapdragon chipset. It's in excellent condition, with the box and charger, so I'm selling it.
I'm just wondering if there's stock firmware for it that will make it more sellable in the UK, that doesn't have a bunch of bundled apps intended for the Chinese market on it.
Is it the same board that's in American or other English speaking Snapdragon models?
If so, will both SIM slots still be recognised if I were to flash American firmware?
Or is there a dual SIM, Snapdragon S7 that was made for an English speaking market, that I could use the firmware from?
Back in 2017, a guy posted asking about the same, he found multiple answers that I find helpful.
Check his post.
Since there's an official TWRP available for Snapdragon devices, I believe there's hope for you, even though not a lot of custom ROMs exist for your variant.
There are ideas you could try, present in the post, but don't forget the warning of flashing other model's firmware, and what could happen to your phone.
Thanks. I hadn't even noticed this thing didn't have the play store on it! The thing is, it does have google play services and google play services updater on it? is that normal?

No, and yes.
Chinese variants don't implement Google Services, just like the modern Huawei devices wasn't allowed to.
Maybe someone tried to install the Google Services packages, similar to what is done on modern Huawei phones, I can't tell you further.
But there's an Oreo Galaxy S9 ROM available for your device, of which will make your device look like an international S7.

Thanks. The firmware that's on it is 100% official, downloaded via frija and flashed with odin. I had a look at the changelog for the official firmware, and it actually does mention that some new Google features had been added to it.
So there's Google services, Google Play Services updater, and a Google section in the settings menu, but no Play store and no Google apps in any of the menus. Google drive PDF viewer does show up in the list of installed apps in the settings menu though. Makes me wonder that there might actually be a way to install the Play Store without custom recovery, that maybe wasn't possible on previous versions of the official firmware.
For now, I have unlocked the bootloader and installed TWRP. I was hoping not have to root it, but it still wouldn't boot after flashing the DM-verity package, so I flashed Magisk and it booted.
I will check out the Oreo ROM for it, thanks. Do you have a link?
I just found out that all I needed to do to get the Google Play store on it was to install the APK file!
As of more recent firmware updates, Samsung have been releasing the firmware for Chinese models with all the underlying Google Services architecture in there already, just without the Play store. Literally just needs the Play store APK.
Been messing around all day trying to flash the Hong Kong CSC file on this thing, cos I really wanted it unrooted for selling it. Stumbled across the Google installer for Chinese smartphones. Tried that, and it was failing on installing Serviced Framework. Turned out that it was failing because a more up to date version of Services Framework was already installed, and all I needed was the Play Store APK from APKmirror.
I have an px 5 xtrons car device that was outdated with android 8, i use the Malaysk rom to upgrade to android 10 first all was good except the random hard reboots that i was getting, so i try a new OTA rom i use a ota htc7 rom android 10, and now i can't get the Google play certification.
Can't install any google apps or update, and can't install any of my already paid apps because it comes with this erro saying "you already own this item" and doesn't let me dowload.
I have tried to register my device on this page google.com/android/uncertified/ with the gsf number . I bought my device in 2019.
Can someone give me some light on how to solve this problem pls, i dont know what to anymore ....pls.
Thanks for your time gays.
Ps, sorry if this post is not in the right forum place.
Hello. Yesterday i installed latest OTA Android version (TB-J606L_S320030_210923_ROW) and noticed that it is really slow and it has even more bloatware that i don't want. I don't need to root it (because of bloatware removal) as i also need to revert it to default state as it was before update.
1. It is possible to find which version i had before this upgrade?
2. How could i downgrade system to previous version (i think it was Android 10 but i'm not sure)
PS: I successfully downgraded/rooted some devices but as every brand has it's specific way to perform downgrade, i'm asking here. Any advice would help and i'm aware of dangers of downgrading/rooting devices (bricking). In any case, it would be awesome to also link unbricking guide for TB-J606L, just in case It's always better to have plan B.
Update: I found source of roms for my device but i can't recognize which versions are old Android 10 and which are the new Android 11.
