Backing up ROM? - Samsung Galaxy S7 Questions and Answers

I'm getting an update on my S7 for whatever reason. Currently the phone is pretty stable for me without giving me headaches like for others. I want to know how to backup the current version of the ROM before the update. Is it even possible without root?

[Q]About rooting and flashing ROM (a noob asks)

i'll try to be brief:
-if i root my phone (s3 mini), will samsung updates cause problems? would you suggest that i also flash the ROM (to smth custom like cyanogenMod)
-does the utility to root the phone provide a full backup of the stock firmware and data? so, if smth goes wrong i can revert back to stock (with my apps and settings. at worst, default factory settings).
-if i flash the ROM, will i lose anything? -say- will i lose proprietary stuff like touchwiz?
-do custom ROMs use the latest android version (that's one of the reasons that i wanna root & flash: to be up to date to latest android version)?
-can custom ROMs update to newer android versions automatically? or do i have to flash again and again everytime there is a new android update?
When I rooted my Galaxy S3 the status of the phone (visible in the preferences/device info) changed to "modified" and I stopped getting updates from Samsung (when checking for updates it said that I had a modified system so I wouldn't be able to get any updates). If you flash a ROM you will indeed loose everything, including Touchwiz, but if you backup your personal data then loosing Touchwiz could be a good thing, at least it was for me. I prefer Cyanogenmod.
Flashing ROMs is frequently done because you actually want to loose all that proprietary bloatware. Custom ROMs also can give you access to the latest Android version right away, wich is a lot faster than waiting months to get last year's version through Samsung. This is one of the main reasons why I decided to flash my phone. I don't use all the "features" that Samsung implements and with Cyanogenmod 10.1 my phone feels faster and has longer battery life.
As for updating, each ROM has different ways of handling it. Cyanogenmod has OTA updates which you can access through your phone "Settings/About phone" section and it will automatically flash them for you.

Yes. You can use clockwork mod (cwm) to backup everything. Its recommended to take your backup using cwm before flashing a custom Rom. So that whenever you want your stock back or something with your new rom goes wrong you can revert back. You can use cwm to restore or use Odin which will make your device like when you bought it. You can restore the data alone using advance restore and your device will be like before flashing custom rom.

i guess, if smth goes bad during rooting i cannot revert back. since for backup one needs to root the device beforehand. is this right?

I dont think cwm needs root access to take a backup. And you can rely on odin always if you got stock rom. So something goes wrong, Odin to the rescue.. So try taking backup with cwm first then root. Anyway if the root update was made for your device then its very very rare for things to go wrong.

[Q] Update strategy for rooted One Mini

hey there,
I have a rooted One Mini which runs on Android 4.3 at the moment. A few days ago, I have recieved the update info for Kitkat 4.4.2.
Now I know that I can not use the regular update on a rooted phone and for the time beeing, I don't even feel the need to upgrade. However, I was wondering about the general problem:
First, I thought about doing a full backup (Nandroid), then flashing back to stock, getting the official update and then flashing the nandroid backup back. However, I realized that makes no sense, since a nandroid backup contains all partitions and therefore would simply overwrite the updated system...right?
Now the question is: what is the most convenient way to stay updated on a rooted phone? Do I really need to flash back to stock, do the update and then go through the root process again each time?
thanks for any info and clarifying!
brokaaa
normally the devs here are much faster in providing an updated ROM then many carriers are with giving you an OTA
I'd go back to stock and take the update. 4.3 was a mistake in my opinion. Att skipped it completely and went from 4.2.2 to 4.4.2 all in one update. Lol or just flash cm11 which is a better choice yet seeing as its already pretty stable and very fast.

Possible to install a customer ROM and keep unrooted?

Im really to the point where i cannot take MIUI anymore. I'd really love to put on a custom ROM but am worried some of my apps would stop working, mostly the banking ones. I know the Barclays Bank app is very picky about root, along with some other banking apps.
Just wondering if its possible to install a custom room and keep my phone without root/locked bootloader (maybe?). Also wondering if there are any ROMS out there that offer OTA updates?
Thanks.

You could unroot after flashing the rom.

Samsung SM-J37V (Help needed)

ok so here is my situation. currently im on stock latest update for this model. i am trying to find the correct stock firmware to download just incase anything goes wrong in the future. What i wanted to do was root the phone even though i wanted the current rom and everything backed up. i dont want to root or modify anything without taking a backup beforehand first. i havent rooted or done phone mods in a while and i have a contract with Verizon for this phone and dont want to brick it or atleast be able to return it to stock before my next phone upgrade incase i have to send it back. im kind of unsure where to start even though i would like to know where i can find the first stock firmware and how to flash it later just incase anything goes wrong. currently i was annoyed by the inability to change the apn settings even to disable ipv6 for the mobile data connection. im not sure it is possible if verizon has it locked and i stay away from ipv6 as much as possible because of privacy concerns so i guess if i cant disable it on the mobile network i will turn mobile data off until it is needed for something i really need while on the go.
here is what i wanted to do:
find a stock firmware file for this model just incase i have to flash to restore all default settings. it doesnt really matter if its updated i would even prefer the original or first one before all the update unless it would be recommended to download the updated one as well.
i was going to root with dr.fone until i heard about magisk because it doesnt modify system boot files or something along the lines of that. the only thing is i would like to know after i root with magisk can it be un rooted without messing up any of the stock files, or interfere with future updates if unrooted?
also i would like TWRP installed as i might want to install custom firmware if possible however if i can i would like to backup the stock recovery before i flash TWRP just incase, unless the custom recovery and everything will be restore with the stock firmware zip that can be flashed above. other than that if i can get this far and get some insight to backup and have things prepared before i dive in to modifying again in hopes i have a backup plan incase anything goes bad.
all help is appreciated and its been a while since i modifying android phones especially for this phone model i been on stock since i had it so im kind of lost in a way since i havent had recent experience for a few years in android modding and rooting in a while. hopefully i can get some feedback as im kind of lost on where to start and dont want to mess up my phone incase i need to get back to everything stock.
waiting for your replies i will get back tomorrow to see if there are any responses. i know this is going to eat up a lot of my time as well and honestly it has been stressing me out even though after i get working on it i should feel better.
Thank You!

Question Can I root my Poco X3 Pro with the default MIUI rom?

First of all. I have a Poco X3 Pro with 8GB RAM and 256GB Storage. MIUI is v12.5.2.0 (RJUEUXM). Model says M2102J20SG. I Have bought my phone 8 months ago and yesterday I decided to unlock it, mistakenly thinking that would let me disable the Xiaomi apps I do not like.
TL; DR:
1) Can I root my phone with stock rom?
2) Can I disable Xiaomi apps on stock rom if I root it?
3) Any suggestions for me with priority on stability over performance?
I have not been involved in rooting a phone in many years. The last android phone I had and rooted was a ZTE Blade and I mean the first Blade, which was like over a decade ago. After that I did a mistake to go on iPhone and then on an LG G6, that never made me feel like I needed to root it honestly.
The main reason I want to root my phone is to debloat it safely, removing/freezing/disabling quite a lot of Xiaomi's extra software, that I just do not want on my phone. MIUI seems quite enjoyable to me, although I have to admit, due to how I am worried that updating it will make my phone more sluggy and will affect battery life, I have yet to ever update it, still being on version 12.5.2.0.
I honestly would not mind to use a custom rom, but my preference is always stability over performance, except if that would offer me extra battery life and the current MIUI's battery life is beyond excellent in my experience, but maybe because LG G6's battery life was never that good since the day I bought it. I am definitely open to suggestions, about the course of action you people think I should take.
You can use adb commands to disable apps, but speaking from experience, you can only disable so much before things start to break, and some of the most annoying things (to me) cannot be disabled without breaking something. Also, when you update the system, all disabled things will most likely re-enable and you have to do the whole process all over again.
If you like MIUI, uninstall apps that can be uninstalled normally and use it as it is, or (and I highly recommend it) install custom ROM. If you want stability, ArrowOS or Crdroid is what you should take a look at. ArrowOS comes with gapps, while Crdroid offers tons of customization and comes as Vanilla (you can flash gapps seperately, if you want).
You sure can root your phone with stock Miui. However, you need to unlock the bootloader, first. It implies loosing all your current data. After that is done, I see no point in running stock miui, I'd go for xiaomi.eu's stable or any of the AOSP roms currently available.
I'm currently running latest crDRoid, which I'm quite enjoying. It's based of LineageOS with added tweaks and is shipped without gapps - you must installed after flashing the ROM.
Make sure you understand the process:
1. Unlock bootloader - you must wait for the 7 days to do so.
2. Flash a recovery. I suggest looking for a beta of a recovery that supports Android 12 decryption, try Nebrassy's TWRP
3. Flash your preferred ROM
4. Root it with Magisk+useful modules: safetynetfix, gms doze, etc.
Enjoy.

No, adb commands is something I definitely do not want to do. I want the system to allow me to actually disable something, without any sort of "brute forcing", mostly cause like you mentioned, I am worried of breaking things. I do not per se dislike google apps, but honestly if I can have as less as possible, it would be better for me. I will look into both the custom roms you mentioned, thank you =)

I unlocked the bootloader just yesterday, so I am done with the first part. I will definitely be checking crDroid, since it seems I can't get rid of MIUI what annoys me the most, which is it's bloatware. I guess since you guys mention to try a custom rom, I should give it a try at least, since i went ahead and unlocked the bootloader anyway. Thank you for the suggestion!

If you uninstall them via ADB on the active user profile they will stay uninstalled even after an update. I did so with 12.5.5 and upgraded to 13.0.1 a while back and they stayed uninstalled.

You could also try XiaomiEU rom, which is basically what you want: debloated MIUI. But to have true control over the apps and features you want, rom like Crdroid is the way to go.
Oh I have seen Xiaomi EU mentioned a lot, but I kept thinking it was just the European stock roms. I just looked it up thanks to you and it indeed looks exactly like what I was asking for. I wanted to stay on MIUI cause I really worry that if it is not vanilla, it might cause problems and most importantly battery life ones.
I probably will be trying to go for crDroid, but for now I am worried I might make a mistake. I would hate it if I ended up bricking my phone, since I love Poco X3 Pro.

Don't worry, you won't brick your phone if you just follow instructions, even then, you would have to do some crazy **** to hard brick your phone, most likely you will just end up with bootloop, which is always fixable by just reflashing the rom.
Read carefully and everything will be fine. I am on ArrowOS since I got the phone, updating regularly, rooting, using magisk modules, zero problems so far. Most of the time, battery life is better since useless bloat won't drain it so much.
Purely for battery life reasons I would personally never suggest switching to a custom rom from MIUI, because with a few ADB commands you can get rid of most of the "useless" bloat. However, if you are concerned about your privacy and don't want to feed Xiaomi with your data, then Lineage would be a good choice as an alternative OS, since at least the official versions are heavily regulated.
The battery life of a debloated MIUI is fantastic, at least in my case.
Ok, this will probably be a bit of a dumb and final question before I jump into the whole custom rome in the next days when I have time. I have seen a lot of times people mentioning TWRP or in general recovery that should be android 12 compatible, rather than the normal v11 provided in the twrp site. crDroid even seems to offer it's own recovery for it's latest android 12.1 version. I am still on Android 11 (MIUI 12.5.2.0). Does that mean I need to first update my phone to the latest MIUI to upgrade my software to android 12, or the recovery is backwards compatible?
I would definitely update to latest stock rom, then flash recovery and install ROM.
Hi!! I'm on the same situation here, coming from a Poco 1 (which is being really hard to let go) to a Poco x3 Pro so this thread is being really useful to me cause I'm basically on the same dilemma, stock vs custom?
I always used custom but when I bought my Poco 1 there was an automated script that unbloated the phone so I did that and stayed with the stock with no issues at all in this 3 years of use.
Now, for the poco x3, the only way of doing the same is by going app by app and removing it through ADB which, as you mentioned, is not that good if you are not sure what to remove so that made me think of going to a custom rom. I mean, I just installed it and all that xiaomi junk is removed.
What I didn't know is that the EU version was debloated so that could be a good option for me but, here's my questionk besides de bloated apps, which is the diference between EU and Global roms? Are they target for the same version of the phone or I could have like NFC disable or radio issues? Cause I though there were different version of the stock roms cause the hardware was diferent between devices.

Just to point out, Xiaomi EU is in a way a custom rom. The Xiaomi.EU community taken the Chinese rom, that has less bloat and more features, translating it and sharing it to people. Just because it it called debloated, that does not mean it does not come with the same Xiaomi Apps. It is still MIUI and that means some Xiaomi apps will still be impossible to disable and also apps like the Xiaomi Security that will softbrick your phone if disabled, still is needed and will cause the same thing in the Xiaomi.EU rom.
It is the main reason I am thinking of trying crDroid, or else like you said, I would not mind just a debloated stock rom, since afar from all the needed Xiaomi apps, MIUI seems quite enjoyable to me. If you check their forums though, you will see even the Xiaomi.EU has it's own problems.

Ohhhh I see! I think I'll try crDroid too and Arrow, as long as it's debloated, the IR works as long with the radio and the nfc, I'm happy.
