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.

Before proceeding, please bear in mind that I'm a complete noob. I'd also like to apologise for any grammatical typo's or errors that you may find in my post.
Greetings,
I need help with few problems / things with my OnePlus One.
First of all, Im currently running my ROOTED OPO with Kitkat 4.4.4 along with Net Hunter v1.0 with TWRP as recovery.
Previously, I had experiences with Downgrading my OPO to Kitkat from Lollipop by following the method posted by a dev named Heisenberg ? ( Sorry if thats not correct, as I did this like a year ago ) by using Calkulins Stock OPO 44S version 1.0.
Now I'd like assistance in :
1. Removing NetHunter ( to install a fresh and clean copy of version 3.0 )
2. Upgrade my Kitkat to Latest Firmware ( Marshmallow i believe? )
3. Have ROOT access.
My main objective is to upgrade NetHunter to 3.0 but I believe it needs Marshmallow for that so, now my objective is to update my Firmware to Marshmallow.
I have no problem if I have to perform a factory reset that will wipe my data as I already made 7 different backups using 7 different apps ( Paranoia ? Huh )
I also have few ideas that I believe i can use :
To remove NetHunter, I believe I can click the Unmount Kali option in the NetHunter Menu. Later, I can try to perform a full unroot and then enable Stock Recovery and then later perform a full factory reset and then use the Android Stock recovery to check for Firmware upgrades and then upgrade them.
Now my major question is? Will this WORK ? - Probably, Probably not, so I'd like the Community to offer me some assistance in this regard.
Here is my current OPO settings :
Model No : A0001 ( DUH )
Cyanogen OS version : 11.0-XNPH05Q
Android Version : 4.4.4
Build No : KTU84Q

Hello evebody!
So , I own a HTC one m9 Sprint, and last friday suddenlty restarts and after it reboots, my signal (carrier/network) was gone!
Everything else is working (Blutooth, Wifi, etc).
At that moment, the phone was stock rom Android Nougat
The actual state of the phone is:
*Unlock
*Custom recovery twrp
*Custom rom Nougat
So, my question is: Can I just install a rom based on Marshmallow directly to a Nougat (via Custom recovery twrp) phone in order to downgrade it?
I already check:
✓ IMEI is correct
✓ Sim (work in other cellphones)
✓ Carrier/network do not have a lock in to my number
Hope someone can take a lookor have any tip in order to recover the signal in my mobile .
Thank you very much in advance guys!:laugh:

Unless you're running official Nougat, I don't think it will be an issue to downgrade to a custom marshmallow via TWRP.
You, however, can't downgrade to official Marshmallow from TWRP. You'll need stock recovery for that.
In case you're downgrading to a custom marshmallow rom i.e LOS 13/CM13, it's better to check the corresponding thread for installation instructions.

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. 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.
Hey everyone!
Recently i came across this pretty obscure device and i would like to know if there would be any way i could install a newer version of android on it, as its currently running Android 4.4.2.
Haven't been able to find much info surrounding this device, but i attached some photos of the info i was able to obtain from it.
Device Name: Myria 502M (Alps mr590)
Board: m601
SoC MediaTek MT8382
To replace existing Android OS ( here: upgrade ) that's what is required:
1. Phone's bootloader must be unlockable
2. A Custom Recovery matching the phone
3. A Custom ROM ( read: Android OS ) suitable to phone

Thanks for the info
But thing is, i wasn't able to find much info about this model of device, let alone see it on TWRP's list or find any custom rom available that weren't on really shady websites.
So i think im mostly out of luck
