Stock firmware vs Custom ROM question - Samsung Galaxy Tab S7 / S7 Plus Questions & Answer

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.

[Q] Flash or not to Flash that is the question...

I am thinking of flashing my Micromax a35 with stock Android 4.1.2 Rom of galaxy S3. I know it is not a custom rom but since it is not of my device can be considered as a custom rom rather than stock for my device. So regarding this my questions are as follows
1.) Is this a good Idea? :fingers-crossed:
2.) My phone has no gps, so gps related app or os components should crash or will they take the whole os down with them?
3.) Should I install Cyanogen mod (Galaxy Vibrant) instead of this?
4.) Can someone give me a super detailed copy of instructions regarding rom flashing and clockwork mod with its working and installation?
5.) Is there a way to remove gps from the settings of ICS rom and from the notification screen as well? in other words can we remove gps functionality from it altogether?
Thank you in advance and I am sorry if any of the above questions sound stupid. I have no idea regarding rom flashing(have never done it before), though I am a developer on android and wanted to switch to ICS.
And there is no forum regarding this device on xda(primarily due to its low popularity maybe) So made a new question here.
No custom rom is available for my device and that is why I had to choose the galaxy s3 rom as an option.
You will probably brick your phone if you flash another device rom. You need to look at this post on porting roms to your device.

Install stock rom on galaxy s3 through TWRP or dual boot

I bought a used used phone rooted with slimbean on it. I did manage to update through TWRP and really like that rom so far. I'll present an app in a few days and want to use an mhl hdmi adapter to project the app on a screen. It seems there's a driver issue and slimrom wont ever support the adapter. So I need to install the stock firmware for the presentation and want switch back after and would like to keep twrp. I could also dual boot it and that would be even better, but does the stock rom supports it ?
Since I know how to use twrp, that would be the simplest way to install the stock rom, How can I do that ?
Is it possible to dualboot the stock firmware ? How can I do that ?
Thanks,
Kristian
EDIT: I have a SGH-I747m (canada) and don't know which stock rom I should use, I don't know the original carrier. I looked on sammobile but you need to know your carrier to find it's original rom.
Wrong forum, this is for the i9300 only.

Need help on rptpe0801 tablet custom rom

Hi All, i need help in selecting a custom rom for RECONNECT tablet, attached is the screenshot about the tablet. I like carbon rom will it be compatible with this tablet?
Recently on the advise of reliance store personal, that this tab is better in performance or equal to Samsung and Apple iPad, I purchased the same.
As usual I rooted the phone without much efforts' as it has 4.2.2 VERSION OF THE ROM.
then Used MTK droid tool to get shell root and obtained / installed CWM RECOVERY
I compiled the custom ROM and using it for the past one week.
When I googled I could not find any custom ROM.
As today I do not have a good WiFi network to port the custom ROM please wait for a day.
BE CAREFUL. YOU BACK UP YOUR ORIGINAL ROM. USER DATA AND IMEI NUMBER.
Backing up IMEI is very important. Retrieval is difficult. Or you use dial pace and type *#06# You will get the number and it will be useful.
I shall port the simple custom ROM based on the stock ROM positively by tomorrow.

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.

Definately download the stock firmware first. I forgot, and I'm having a hard time getting the right version.
I did not check headphones yet, but audio/video is all well. Currently I have another OS (Evolution) installed, I might revert back to LineageOS in a few days. I will check headphones then.
Main issue I'm having now is the mobile service connection. It's very unreliable, and the data is always off. Also on Evolution OS, so it might be the phone's hardware. (Did not check out of the box.)
Edit, okay, back to LineageOS 17.1. Don't know how, but the modem works now.
It was about this file: amss_fsg_poplar_tar.mbm
I think because I installed Lineage 19 without simcard.
I tried to flash stock ROM, but could not get it to work.
A lot of "invalid Zip format" errror messages...
So I tried LOS 17, and it al worked, then dirty installed 18, and then 20. And modem worked, but then failed.
Back to 17.1 again, and up till now no problemos.
