question about ROM - Samsung S9 SM-G960F (PHN) - General Questions and Answers

hi everyone, I am new to this forum.
i've been interested in rooting / mods for my old Samsung s9 to give it a new life.
I did so by rooting it using the TWRP app in combination with the Magisk V23.0
now what happened was that i was downloading some random apps yesterday and for some reason the phone went on bootloop...
i accidentally deleted the system without making a backup lol... a little stupid of me...
now it keeps telling me that i've no OS on my phone. i was thinking that i could easily find the ''un-edited'' or simple version of my original OS. but i've looked through many sites without succes.. either looks 2 good to be true or just fake...
is there anyone who can advise me on what to do? i just want my phone to work with any OS right now... but which one is the cleanest or best to use? i do prefer a newer os like 10
thanks in advance!

If you still have access to recovery mode, your best choice would probably be installing LineageOS. It's the most lightweight ROM and many ROMs are based on Lineage. From what i can see, your phone is no longer officially supported.
I found this one based on Lineage 18.1 (Android 11). Before installing, take a look at the bugs, working, and installing sections.
And don't forget to install the Google Apps after installing the system and before rebooting.

that looks crispy. i appreciate your quick & good advise. can you tell me wether i can still run Magisk on it?

Yes, you can still flash Magisk or any type of root with both the OS and the GApps.

what i'm consider about is, wether a region code CRC matters?

Recommendation for Oreo and maybe Custom ROM

I'm not really a very advanced user, but always had rooted devices and two that I flashed Custom Roms. This is my first Samsung, finding Touchwiz to be very different from what I used before.
I bought the S7 (930F) and had the news that it was going to be updated to Oreo, so I decided waiting for the update before tinkering with it.. But the update never came. Finally this month Samsung released the update for my region, so I would like to know which would be the best way for me to start finally using my phone that I bought for over 2 months!
My phone is still with Nougat, is it better for me to get the OTA or to flash the Firmware I downloaded from Sammobile? Any of these methods better than the other in preventing errors? I always found in PCs that a fresh clean install was better than an update, but with mobiles I don't have the experience to say.
My main objective is to experiment before doing a debloat as I'm still not sure what might be useful for me on Samsung's bloat (you are welcome to point me what is useful and what is not).
I did see that some of the Customs ROMS have different camera apps and some people were complaining about this, I particularly liked the S7 camera app and the Pro option, that's what holds me back in flashing a Custom ROM atm.
I would like to Root and I find Unlocked Bootloader to be useful to have Xposed Framework and other things that I can do having it.
As I'm a relative newbie, what would you guys recommend me doing? Please help
tl;dr: I want to have Oreo, be able to debloat, want to root and unlock bootloader, not sure about Custom Rom.
Lineage if you want basic and simple (sort of like stock Android). Resurrection Remix if you're a customisation nut (not a slam... I use RR).
If you wonna full samsung u need flash base firmawre custom roms only 8.0 android
If you dnt need samsung integration (pulsometr doesnt work) you can flash 8.1 roms try cosmic os or Lineage 15

SIM Unlocked G920W8, 9.0 and 10.0 ROMs no longer detect SIM.

*SOLVED: see reply*
The ROM I used before was LineageOS [10.0] and used a custom ROM with Android 9 before that. Needed to unlock my phone, and couldn't do that on Lineage, and had troubles flashing firmware with Odin, so I ended up using FrankensteinS6. The Stock kernel seems to let me input the NCK, and unlock the phone. So that's luckily finally over.
For about 4 days now I've been formatting phone and trying again and again. FrankensteinS6 works, some other 6.0/7.0 ROMs work. But LineageOS now enters a bootloop, and Pixel Experience (9.0 and 10.0) and Evolution X 10.0 don't detect the SIM. The ones that don't detect SIM also show no IMEI, which was worrying at first because I though I lost a partition.
Possibly related, the ROM of Pixel Experience Android 10.0 for G920W8 will not install because (paraphrasing) "This device is zeroflte, this file is for zerofltecan, zeroflte***, zeroflte***" claiming that my phone isn't one of those models. I got this S6 from Bell Canada, and I still have even the sticker that says it is a G920W8, not G920F. However, the Pixel Experience ROM for G920F flashes fine (sans the main problem).
I don't know the exact LineageOS ROM I used before, but I've tried all of their 10.0 releases, tried redownloading, and I get the bootloop every time. I see some info online of flashing modem firmware, but... I don't even know where to start with that. As I mentioned at the start, Odin is crapping out. I couldn't flash firmware with it, because it would reject the phone right after I started flashing. Anything I could do within TWRP would be great. I moved it back to FrankensteinS6 for my sanity, I started doing this Sunday and I'm starting to repeat steps over and over hoping that it just solves itself.
I tried to keep this straightforward, and I'm sure I did a bad job. I can extrapolate on what I have attempted. Please tell me what I have to do to get an android 10 ROM working on this old beauty again.
I do not have all the solutions. As per my tests with my SM-G920W8. I have managed to find ROMS and try them out. I have only seen Nougat 7.0 ROMS to work almost flawlessly. NOT 7.1.2, important, 7.0 only.
I have also tested some Pie and v10 ROMS like Pixel Experience. The ROMS boot nicely but since I do not use a SIM card to call as I use SIP phone numbers and require WiFi. But that left asside, I came upon serious camera issues no matter what I try. Up to now, SamStock ROM is pretty much the best Stock ROM I found but I always need to run the Magisk UNINSTALLER before re-installing the latest Magisk version..
As for Kernels, well, Anything that is oriented with Lineage OS, I've had camera issues even with Nougat v7.0. So basically, the only ROMS I found good, as of today, for now, are stock ROMS v7.0. But, to do your tests, Even if you have a 920F ROM, you can download a 920W8 kernel as long as you download a kernel which supports your installed Android version. Also make sure to download the proper Stock or AOSP kernel (AOSP for LineageOS). There's not many but there's a few ones that work properly.
Another option is to download an AOSP ROM that works for W8 phones, unzip the file and grab the boot file inside corresponding to the W8 or T-Mobile version. You simply unzip your real ROM you want top install, replace the boot file for the one you got and rezip it. This made my phone boot properly for some F version ROMS but again, not without issues. That's why, I really suggest v7.0 Srock ROMS. I hope this helps you a bit. Again, you can have your own tests and other users may have other answers, but this is based off over 30 bootloops in my case of trying to mod a ROM for the W8 model. It's not easy to find a good one for Canada, I admit!!!
I flashed TWRP years ago, and I found out that I had a G920F version flashed. I don't know why Lineage allowed me to use SIM before, but rectifying this issue seems to made the SIM work in newer versions.
I don't know what the S6's predisposition to having crashing cameras is, but I have avoided this in the past by using custom camera apps, like Open Camera. This has saved me every time.
As for the boot loops... I think another thing that helped is that "format data" doesn't wipe the OS. When you are in recovery, having issues with bootloops in various ROMs, try advanced wipe, and wipe the system. It didn't fix right away, but the time I got Pixel Experience 10 up and running that was the trick.

I first rooted, then installed twrp, but couldn't boot to stock after flashing twrp, so tried flashing gsi arm64 ab, then gapps, and kernel, then it booted to welcome screen, but always random reboots all the time.. so I went back to stock..
From my experience with custom ROMs, I haven't found any good one with no bugs or crashes so I would only recommend one to use rooted stock. Just root your stock android and stick with it.

cause i want to get this phone and i want it to last long
There are yet no custom ROMs for this device as of what I have seen so far. *Talking about a ROM that is fimware supported and not a generic one* You can install GSIs, which are love and hate. GSIs are a generic images which can be run on any andorid device with treble support and API LEVEL 29 or higher, aka starting with android 9(oreo). There is no support for VERIFIED_BOOT. It uses HIDL vendor interfaces. I can only tell you to wait if you want a fimware supported ROM, LinageOS is beeing build. I'm currently playing with my ARCH build, I will make a ROM too, but when I get everything setup as it should be. I talked plenty and still do both on these forums and on telegram, you can find some my interesting sayings in my Explaining Thread... Forgot to meniton I would recomend you to try LIR or Los19 if you are looking for a good GSI. I still haven't tried Los19 because doing stuff with ARCH...
Cheers,
Krypton

Ressurection Remix on A8

Hello everyone,
I am creating this post because I would like to know if someone has already installed Ressurection Remix on a Galaxy A8 ?
I saw some tutorials that are explaining this is possible,but when I go to the Ressurection Remix official download page, I cannot find which file is specific to the galaxy A8. Actually, I have some difficulties to understand the files names : Raphael, Sakura, Jason,... Are theses names code names for différents phones ?
I may add that the bootloader of my phone is unlocked, and I am using TWRP to flash zip files.
I didn't treblelize my phone thought.
If you have some other custom rom suggestions, please do not hesitate to advise me.
You can install RR through GSI, by this link
You will have to trebelize your device
Because it's a gsi android 10, you can use vendor quack
Treble Guide
Vendor Quack
Thanks for your reply. Yes I saw that it was possible to treblelize the phone, to install other rom like the very famous lineage os.
But I am little bit hesitant about this procedure : is everything working well with the phone after a treblelization ? Has anyone tried this method?

Treblizing the phone itself does not cause any problem rather it enables you to install different GSIs. Regarding GSIs, each have there own bugs and you have to find them on the GSI thread if available or if they have telegram or github support.
Hey, just made an account to respond to this as I just discovered there are per-device pages on these forums and saw this post, I have done exactly that and been running it for 2+ years now, so far I have had no majour problems wih it, the only majour caviat is that after trebblimg it and installing resurrection remix It seems to freeze when trying to display the charging animation if the phone is off and it plugged in, it still charges without any problems, tho to boot it when in this situation you need to force shut it down using the volume_down + lock buttons and then immidiately after use volume_up + lock buttons to boot into recovery, then you can boot to the normal system from there, I have a TWRP recovery but I think the stock one also allows to resume booting the normal system.
In these last months I had a few weird bugs like the screen brightness beeing locked to automatic but that went away after a reboot and only happened 1 time.
I also installed magisk and a few other small tweaks and things and everything works great, also all resurrection remix customization options.
Actually in the last few months something broke because the safetynet checks fail for the ctsProfile, (most apps like my banking app tho still work fine by using magisk hide (i think it's because the safetynet basicIntegrity check still succeds) and the update page seems also broken (tho no idea about when this broke exactly as I haven't checked it in years), everything else is still fine tho, I might try re-flashing it to update to the new majour resurrection remix when i have time and the will to backup and move everything, something could have corrupted or maybe an update broke it, no idea.
My phone reports resurrection remix 7.0.2 and Android 9.
Hope this is still helpful.

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.
