Ive managed to get custom gsi working on samsung galaxy m40... but i cant get volte to work, nor can i get custom recovery to flash patches... - Samsung Galaxy M40 Questions & Answers

So i have a samsung m40. and ive managed to install pixel experience gsi on it, WITHOUT TWRP.. but it doesnt work with magisk or supersu.. basically the binary is read-only.. if i make changes via build.prop editor, it wont save it.. so basically i cant get volte working on it.. i can root the official samsung and it works flawlessly.. but its not the same as a custom gsi.. is there anyway that i can extract the services that enable volte in samsung firmware and install them in the custom os..? its a hunch but if someone has a fix for samsung m40.. it would be great.. if you want ill post a thread about how i installed the gsi..

Can you make a detailed guide on how to install the custom gsi rom
Also a download link for any customisation that you might have made on the rom

Rom Question. S6 Edge - SM g925Z Japan Softbank.

I Have the SM G925Z Version of the galaxy s6 Edge [Japan SoftBank]
I See many Roms that say "Works with many g925 Versions !" but the Japanese Z Version is never listed anywhere.
only the F T U V P etc etc versions.
If I use TWRP 2.8.6.0 to backup my current Rom, can I try these other Roms and safely return to my Stock Rom
if cell or wifi service stop working? If I try 5.1.1 Roms, I can not return to 5.0.2 roms?
Can I use TWRP to install a 5.1.1 rom that I download, even while my current Rom is 5.0.2 ?
or can I only install Roms using Odin Flash tool ?
My ZTE Warp phone was able to install Roms from downloaded Zip files with TWRP.
But I am not 100 % sure about the process.

First the s6 edge is a different style of device. To install 5.1.1 roms on the device you have to be on 5.1.1. Same with 5.0.2. Yes you can try any rom from the s6 and the s6 edge rom so long as you flash a special kernal for your device that makes the rom work on your device. If cellular data does not work, revert to your nandroid backup of your origonal os and flash another rom and you'll be good if that one works. Just repeat if the roms dont work or if you get tired of it then just stick with your stock rom which should be your nandroid backup.

Thank you. I can understand this, except for the kernal part, please explain.
How can I backup my current Kernal so that I can return to my Stock Rom backup.?
will a TWRP Nandroid backup do that automatically ?
how do I install the correct Kernal? with TWRP ?
for example, from the ROM installation , it says
[5]Install Zip from storage
[6]Flash The Capsule ROM
[7]Flash arter97 kernel
[8]Flash SuperSU
[9]Reboot
Im assuming 5 means, copy the rom to the phone, 6 means use TWRP to install,
so flash the kernal after the rom ? with Twrp ?
how can I backup my kernal first? so that I can return to my 5.0.2.
and last question, you said I need to be on 5.1.1 to try 5.1.1 roms.
the Japan SM g925Z is a 5.0.2 rom atm, they never updated to 5.1.
most of the roms I see are 5.1.1
Does that mean there is no way to upgrade to 5.1.1 while on 5.0.2 ?
or does that mean, if I flash a new TWRP and 5.1.1 Rom, I can just never return to 5.1.1 ?
Does TWRP Mean Kernel ?
maybe that is what I am missing.
I already have a working TWRP.
some roms do not mention flashing kernels in the installation, some do,
does that mean it does not matter? or does that mean that the installation guide is terrible and people are going to brick ---- if they dont know about it ?
Im not exactly sure the difference between kernel and Rom.
To answer your first question, the nandroid backup you do in twrp backs it up because it is a required portion of your rom. Which also answers your second question as yes.
The answer to your third question is you have to find a flashable zip of a custom kernal for your device. You can also try restoring your boot from the nandroid which contains the kernal and if that one doesnt work flash the custom kernal zip.
Next i need a link to the rom your trying to flash to check it out.
The only way to install 5.1.1 roms is to be on that android version. The reason is that android uses an sdk platform and 5.0.2 uses sdk 21 and 5.1.1 uses sdk 22 so those are incompatable with each other.
No way to update that device to 5.1.1 unless it is released for that device or unless the hardware sources are released for aosp roms which may be a while where samsung has not released them yet due to the new Exynos processor that they recently created.
No twrp is your recovery but it backs up your kernal with the backup.
Those roms are for specific device varients and will work without installing a kernal because the kernal that it needs is for the devices they are meant for.
The others that say install kernals are ones that didnt have the kernal put in the rom zip.

Either that or they didnt modify the kernals in the rom zip to the specifacations that they wanted so they fixed it and posted the kernal.

thank you, that does explain alot.
I am not sure which Rom I should try. None of them actually say sm g95z.
Which roms would you recommend I try first?
I am not sure any will work, they all appear to be 5.1.1 only.
which means my 5.0.2 system can not test any of them.
or more specifically, if I upgrade to 5.1.1, and they fail to connect to wifi or cellular, then I can not return to 5.0.2 I guess.
Do you know of any that are 5.0.2 ?
those should be safe to try I guess.
I just want to get rid of the 500 retarded A-- Samsung apps that auto update.
I dont need Sfinder X_x, I dont need quick connect, I REALLY dont want virus protection from samsung clogging up my performance.
I have read about build.prop tweaks and updates, but the sm g925Z version did not get 5.1.1 updates, so those fixes do not work.
I do have Root access already, but with TWRP 2.8.6.0 (Because its said that it doesnt trip knox).
but I can not un-install these fkn bloatware apps, even with root access.
This appears to be a 5.0.2 Galaxy S6 Edge Rom.
http://forum.xda-developers.com/gal...edge-g925fxxu1aocv-v1-0-deodex-aroma-t3102974
but it says G925FXX, my phone is G925ZZ
I should be able to test it, and return to my g925ZZ TWRP backup pretty easily right ? since it is 5.0.2 ?
Just to confirm for other people.
I tested the VNRom 5.0.2 for G920F
it ran like S--T.
I used TWRP backup to go back to Stock 5.0.2 just fine.
no problems.

How did you the root access for the sm-g925z?
I too have the same device and searching for the root access.

Please post link to the files well..
Oh yeah if you have the link to download the stock rom 5.0.2 for the device post it as well.
It will be great help.
Thanks..
I searched alot.

Hello, Have you found any compatible rom?

Newbie question regarding recovery and Magisk

Hey guys,
I mangaged to install a custom ROM on my 9s Note (Curtana). Now I want to install the MIUI stock camera (48mp) module because the one which comes with the rom is quite poor on options. I have many confusions about the next steps and hope to find some help. I posted my questions on the thread of the ROM but unfortunatly did not get any response.
My questions are:
Is it correct that I need now to change the stock recovery to a custom one, for example TWRP in order to install custom addons?
Then I need to install Magisk which is used to install this custom ´addons´?
If this both are installed, will I be a SU automatically?
Will my banking apps still work or stuff like Spotify, WhatsApp? It does now on the custom rom which is amazing.
Is it possible to backup the original recovery partition? Then at any point in the future go back to it?
Can I install the stock MIUI ROM 11 or 12 with a custom recovery?
I would be so thankful if somebody could help me!
Cheers,
Cho
1) if you have installed a custom ROM, chances are you did it with a custom recovery.
2) some addons require root privileges, which can be had with magisk
3)yes, having magisk installed successfully means yiu will have rot privileges
4) banking apps, google own safety net checks and magisk are in a constant race of outpacing each other, magisk seems to be loosing now with tighter controls in newer android version. so dont expect your banking apps to work with magisk anymore.
5) it is probable on some devices with mature development not sure with this
6) not in its stock form, usually people build alternate builds of stock ROM that can be flashed with custom recoveries.

Can i change my boot animation on my Samsung A11 ?

I just got my samsung A11 rooted by following and learning guides on youtube and xda forums. Now i want to change my boot animation but when i tried to download the Boot Animation App in playstore i saw a comment saying that it does not work on stock rom. So the way i rooted my phone is getting the same baseband version and CSC firmware from sammobile. After getting the same firmware model i flashed the firmware to my A11 (AP file rooted by magisk) after successfully flashing using odin and got a pass does that mean that my firmware is still a stock rom because its the same baseband version and CTC or is it a custom rom because i rooted the AP file and flashed a rom that i found on the internet? I wanted to ask because im afraid i might get bootloop like how i installed a safetynet module and had to reset on safetymode.

AFAIK you just need root, not necessarily a custom rom.
I found a general guide here:

As it's not explicitly für die device, no guarantee that it will work.
Backup everything important before, and good luck!

Stock firmware vs Custom ROM question

I am having problems using GPS Joystick on my Tab S7. It intermittently disconnects and send me to my current location and always does that when I try and use a GPX route. My tab is the Samsung Galaxy Tab S7 SM-T870, Android 11, with the stock firmware. I rooted it with Magisk 23.0, Smali Patcher and I use GPS Joystick for location mocking. Someone on the discord said the stock firmware is preventing it from working properly and I need a custom ROM for it to work properly. The suggestion was to install ArrowOS, I assume this is a custom ROM. Do I have to start all over from the beginning or can I install custom ROM where I am at? Does the custom ROM wipe everything and have to add it all back in? I only use the tablet for playing games and I don’t need anything fancy. Would ArrowOS be the best way to go for this device or any other recommendations? All advice is welcome and thanks in advance for any assistance.

I have also a SM-J600FN/DS, I am using OFOX, to first install the lineage-17.1-20210213-UNOFFICIAL-j6lte.zip
[ROM][UNOFFICIAL][j6lte][10] LineageOS 17.1
Install and running was OK, but like written some pb with phone calls.
Then I tried an other lineage-17.1-20200715-UNOFFICIAL-j6lte.zip
install was OK but at first start never trebuchet ended!!!
So, test the Arrow [ROM][10][J600X][ARM64] Arrow OS
Install and running was OK, but like with lineage-17.1-20200715-UNOFFICIAL-j6lte.zip same pb with phone calls.
I am thinking these 2 ROM with call phone pbs are not for the J600FN/DS but for the J600G
At last test the [ROM][10][ARM] YashxOS for Galaxy J6 2018
Install and running was OK and ALSO the phone calls :+)
Its default is to have gapps built in so I would like to root it to remove unwanted apps!
The .apk KingoRoot and kingroot fail to do so! (failed also with the last stock ROM)
