Flash stock rom without data loss - Samsung Galaxy S9 Questions & Answers

Hi there!
It's been a few years since my I flashed Firmwares on my S6 with Odin so please forgive me if I'm not quite up to date on that topic.
Background: For installing custom emojis on my S9 I wanted to use Zfont, however, this doesn't work. I did some research and it is said that zfont won't work on debloated Samsung firmwares. Next step would be temporarily re-bloating my debloated device. I tried, however, I couldn't manage to reinstall all the Samsung apps since I don't rebember all of the packages that I removed and the few that have been recovered were not enough to make Zfont work.
In the old days you just could flash the stock rom on a working device to get all the uninstalled factory apps back. Is this possible with Android 10 and OneUI 2.5? Will my data be wiped if I flash it with the current firmware? Do I need OEM unlock?

Download latest firmware. Unzip it, there will be 5 files to flash with Odin.
Home_csc - will keep your data
csc - will wipe your data

Thank you for the info.

Yes
When looking for firmware use your baseband version number in about phone-software info as a base to look for firmware on the net. Just bare in mind you can't downgrade (bootloader/binary) firmware ( 5th number/letter from right of firmware name).
You can also use frija pc tool to download lastest firmware. It will be quicker than sammobil. Your have to search here on xda as i can't post links at the moment.

The flashing process went fine. Unfortunately, it didn't bring back the disabled apps. Probably because they have been disabled via adb for user 0, which means that they're still on that device but inactive for the current user.
At this point, I just don't want to spend any more investigating which missing apps causes zfont not to work.

[Q] Rooting problems

Hello i've some problem with my T-Mobile Galaxy Note 2.
Last week i updated my phone on Android 4.3 version.
Unfortunelly i had a wifi bug and I couldn't connect to internet, so I decided to downgrade it to 4.1.2. I've flashed my stock ROM with the newest one. (thanks to this link http://forum.xda-developers.com/showthread.php?t=2102380 )
Afterward, i would rooting my phone and install custom binary CWM by this thread, option 2.
However i can't modifiy system files. I consequently would verify my status root by Titanium Backup. And that's really strange because it is already rooted.

So i'd like to know how to resolve my problem, i how to modify system files?
(PS: sorry for my bad English!)
PS2: That's the same thing if i connect it on SSH/FTP protocols, unable to modify too.
I have T889 version and I just updated today with 4.3 with no problem.
I would say the best thing is just start from scratch and reinstall your app.
I don't even use TB anymore, I used to but I just happen to run into problem a lot.
I decided to just reinstall apps everytime I flash rom.

So, do you advise me to re-install the 4.1.2 version and re-root again?
update: I've re-installed and re-rooting my stock rom and nothing has changed. Can you help me please?

Try using the Odin again and when you full wipe don't even do anything just update to the original 4.3 via Tmobile.
After that install CWM or TWRP, Like I said I never had any issues installing Rom back and forth.
Just don't skip a step and never rush things.

What Could Be Causing This High Usage Of Data While On Mobile Network?

So I was driving back yesterday and my phone notifies me that I'm reaching my data limit. I thought, "That's odd, I've only used 0.1 GB". So I look down and see this monstrosity of data being used by the damn Android OS. How the heck can you see what would individually be using data in the "Android OS" package cause it could be any number of things. I'm guessing it could have been a system update pull but I did disable OTA updates in developer settings. I have root as well and I would like to freeze that process with Titanium Backup if anyone knows what that process might be on the Pixel. Also any other suggestions as how to further troubleshoot this would be appreciated.

It's the update pull even though you are updated. We have seen this a few times with others. Get it updated.

Well when I go to system update and choose to install update it says that it failed. Any advice on that? Can you not properly install updates while rooted?
In terms of updating to the latest OTA I followed How To Geeks - FlashFire Guide which put my device into a endless bootloop so I don't recommend doing that.
Still looking to see if anyone knows what to freeze in Titanium Backup on Pixel to block OTA updates from downloading. Thanks.

You must of modded something that is stopping it. There is a way to sideload the OTA, but the third post in the thread below is how I do it each month. Have ro reroot afterwards.
Pay attention to the part where you remove the-w from flashall bat file. That is what saves your data.

I ended up flashing the original stock ROM off Google's website and then went threw the systemless root methods mentioned here.
I now have the below:
Android: 7.1.1 ROM: Factory (Rooted) Kernel: 3.18.31-ElementalX-P-1.08 Build: NOF27B
im having tons of data through the same thing. I ran a data manager app and it said its google.uid.system:1000 . I reset the rom to original as I have not installed any other rom then googles originals. I have some of the highest data downloads its crazy. I even turned off back up picture folders. Here is the data.

Android OS using lots of data

Noticed my Android OS is using almost 1gb of which doesn't seem right.

Any ideas?
Edit 3: Updating will fix this properly.
Edit 2: That didn't fix it...
Edit: I've seemed to "fix" it. From my reading it is a background service trying to do a seamless update in the background. I disabled "com.qti.service.colorservice" using titanium backup and restore and it seems my background data usage has stopped. No negative consequences so far but it may prevent seamless updates. Another fix would probably be updating to the latest patch version...
Idk but I hope you get an answer... Been killing my battery.

That would make sense if he was on stock but if he's using Titanium Backup his phone is rooted and might have other modifications. Flashing the latest factory image or if he's on a custom ROM doing a clean flash of the ROM would probably be the best idea under the circumstances.

It has been a while but I'll reply so anyone else who comes will know. My state before and after was the same. All that changed was my OS version. Flashed the flash-all.sh after removing the -w, flashed the April bootloader (so no boot signing stuff, not the safest or recommended thing), booted TWRP, flashed twrp, flashed supersu, and then rebooted. No other mods besides adaway.
Are you on stock, rooted or unlocked bootloader? I had the same issue on stock (unlocked bootloader) where it was trying download an update repeatedly. I had to actually flash a custom rom to make it stop. Verizon did credit me back for the data it used.
Feel free to read my forum post there and try those steps. - https://community.verizonwireless.com/message/1500910#1500910

Problem rooting F41 with magisk and Android 12

Hi, i have rooted a few phones in the past without problems but it´s my first samsung and nothing seems to work... Read a lot a tutorials, tried a lot of things and for now, no success in any...
I'm on the latest version of Android (12) - ZTO-F415FUBS2CVF1
I did unlock the bootloader without problems... Extracted stock rom boot.img, patched it with magisk 22104. Put it inside a boot.tar, flashed it in Odin with success:

After the patch, i always go straight to stock recovery and wipe data...
It´s really weird, when i install magisk, after the flash, it only says this:
I also did try to follow magisk instructions and flash the whole stock rom with the AP patched but it gives me an vbmeta error, so i reverted to stock firmware and kept trying to patch only boot.img...
Also tried to revert to android 11 with Odin but it gives me an wrong version error on download mode...
I don´t know if i'm using the wrong magisk version, or something is missing in the tutorials... Also tried to find something here but nothing seems to work... Can someone help me ?
Same problem here. VBmeta is giving me a lot of trouble.
Loking foward for a solution...

Can I see the error? It may be because flashing just the ap in the first place shrunk your space.

Question I have several problems when I get to Miui 14

The first thing I want to say is that I'm using Google Translate
I just updated the EU ROM MIUI 14 and I have 2 errors below.
+when I first uploaded the rom, the status bar was normal but then the status bar, the notification panel, it was completely transparent,
+When I go to Google services and some parts of the settings, it changes the background color to light brown.
I need to know if it's a ROM bug or if I've
installed something wrong, and I'll fix it.
looking forward to help from everyone..
I know the EU ROM can't update via OTAs. But on MIUI 14, I open the update section, there is a message "Choose to update via OTA or via TWRP" I also see the section Select update package in the settings section
Thank you.

First I thank you for your reply.
i tried factory reset but it didn't fix it.
my case is like reading mode, but i don't turn it on at all both before the upgrade and after the upgrade.
When I upgrade, I can restore previously backed up data.
Which EU version you installed is it Stable or Beta.
When this happens it is advised to install original version of miui and then flash EU one to resolve issues.
upgrading from 13.0.6 upwards shouldn't be an issue i expect you must have had something on the system which is broken before hand.

i am not good at computer, before upgrade was running miui 12.5.8 .
now i need to go back to 12.5.8 or to miui china.
if back to 12.5.8, I asked the store where I bought it and flashed the rom, it said "if back to the old version of 12.5.8, the phone may leak.
if i go to miui china, can i update myself via ota to go back to miui.eu.
