Hi All,

I'm a completely noob (new at android world, never flashed anything). Please, hope you can help.

Currently have TWRP 3.3.1-1 working on a new s9+ snapdragon (SM-G9650 Latin America), however Reboot > System is resulting in bootloop.

I was searching for a Custom ROM for my model to flash and try to solve the problem, but couldn't find one (also I'm not sure it is the right way to go). Also searched for Stock Android but I'm not sure which is the right one for my model.

Can someone help? Thanks in advance.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] plrodrigo:
here you can find official roms for the g9650 model

https://www.sammobile.com/samsung/galaxy-s9-plus/firmware/SM-G9650/

Restore your phone and follow correct step in op
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] chrccruz:
Thanks, problem solved.

Time to try again. I believe I messed up on step 5 allowing system to be modified till disable dm-verity (not sure). I also couldn't find CROM from galaxy apps store.

In order to avoid bootloop shall I flash klabit kernel and flash magisk (step 6)?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
I don't believe crom is necessary anymore.

But umm.... Step 6 is there for a reason so yes flash the kernel and magisk
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Ryan.M:
Mobile network has stopped working after rooting + kernel. Says that only emergency calls are possible
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
No idea what could cause that. Never had an issue like that. What else did you do? Because rooting alone will not touch anything with mobile network.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Ryan.M:
Nothing really. Just that

I have flashed stock rom and network started working again. Will reroot and let you know if the issue persists.

Thanks for your reply

(edit) It stopped working again.

What I did step by step (SM-G9650):

1. Flashed twrp

2. Wiped data

3. Flashed klabit kernel v5.4

4. Installed Magisk 19.3
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
I honestly have no explanation for that, that's extremely weird. I'll discuss it with some others and see what could be going on. Did you flash the decryption zip?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
You say you wiped data.... Did you format? Or just wipe. There is a difference. Formatting is what you should be doing. It requires you to type yes in recovery and whatnot.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] stang5litre:
What carrier you on? If I were you, I would Odin to the newest fw and then flash everything. Sounds like you flashed a file that wasn't meant for your phone which is causing this issue.

stang5litre Edition 5.0 Roms
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Ryan.M:
I formatted it.

The weird this is that now I can't even connect to a network after I have flashed stock. And when I search the phone by IMEI number I keep finding some LG phone which is blacklisted. I checked that on several websites

Could something mess up the IMEI number?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] stang5litre:
Also you say "nothing really" which makes it sound like you flashed something[emoji848]

stang5litre Edition 5.0 Roms
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Not at all. Twrp and rooting doesn't touch anything regarding the IMEI. You've got something weird going on. And it sounds like you've done more than what you've described.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Ryan.M:
Sorry. I don't think I fully realized the connotation of that phrase. I think it's obvious that English isn't my first language :)

---------- Post added at 01:18 AM ---------- Previous post was at 01:16 AM ----------

That's weird indeed. Will try to flash another firmware, can't think of anything else I can try right now
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Flash latest stock firmware for your region.

What model and region is your device?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] stang5litre:
I asked and gave the same advice maybe he will trust you. [emoji106]

i still wait root on my 965u
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
You'll be waiting a long time since it won't happen. U models are stuck and will not get root or unlocked bootloader.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] BloodKil:
Maybe, have hope for qualpwn changing that though if some dev's can dig into it soonish.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Don't update past July security patch if that's your hope. Qualpwn is patched in August security patch update.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Tostis:
I've installed G9650ZCU5CSFB but I can't manage to install TWRP anymore :(

After upgrading to G9650ZCU5CSFB it has shown "KG STATUS : Checking" so I couldn't install TWRP. Today, after 7 days i managed to install twrp-3.3.1-1-starqltechn.img.tar via Odin but I can't boot in recovery because it goes in bootloop. My only option is to flash again AP of G9650ZCU5CSFB so now the counter is resetted to 7 days.

What I'm missing? Once I've flashed the whole stock firmware via Odin, what should I do to install TWRP and then root the G9650?

ps. last working firmware was G9650ZHU4CSE7 with TWRP 3.3.1-0 and klabit kernel v4
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
You should read and follow the guide provided and do not go astray and you'll be fine and rooted with ease.

Also my kernel supports all pie firmwares. Even the very latest August patches.

You're not being very clear/honest about your process because simply flashing twrp will not cause bootloops.

Use twrp 3.3.1-1 (latest available from twrp website) and my latest kernel available in the thread and follow the process properly and you'll have no issues.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Tostis:
Starting from G9650ZHU4CSE7 with TWRP 3.3.1-0, klabit kernel v4 and Magisk, this is what I did:

- flash stock G9650ZHU5CSFB with Odin v3.13.1

- Restart in download mode

- flash twrp-3.3.1-1-starqltechn.img.tar (AP tab, no auto reboot)

- restart in recovery

- bootloop

So I flashed again G9650ZHU5CSFB and started the phone. Now it shows:

FRP LOCK : OFF

OEM LOCK : OFF

KG STATUS : Checking

QUALCOMM SECUREBOOT : ENABLE

KG STATUS means that I have to wait 7 days before I can flash recovery?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] tylerhole:
Flash stock, boot system and connect to WiFi and run through setup completely then boot to download and flash TWRP.

Edit: no need to wait 7 days if kg status is checking
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Tostis:
I'm sorry, that was my fault. I wrongly flashed twrp for starqltechn instead of star2qltechn.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] stang5litre:
Just slow down and look at all files. Easier to ask a question then not to and mess up the device

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] schloop:
can someone clarify on the steps?

"After flashing, boot into twrp. Make sure to NOT allow system to be modified till you disable dm-verity! (otherwise your phone will be stuck at bootloop). "
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] tylerhole:
What needs clarification? There will be a pop-up when you first boot into TWRP that days "swipe to allow modifications to the system" or something of that sort. Do not swipe the swiper. After you disable dm-verity, the next time you boot into TWRP you can swipe that swiper.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] schloop:
thanks!
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
how do i find the CROM app that you say i need to download from the app store
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
It is no longer needed. I haven't had a chance to update the instructions.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] amato:
Only Official bienaries are allowed?

Hi, <i have a error message , after do al process, installing kernel and rmm patch + force..., install magisk, the phone start good, but later i do a manual reboot and notice me " COnly Official binaries are allowed to be flashed

Who I do wrong??:confused:

Thanks in advance
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Looks like you didn't flash the rmm patch.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
I keep getting fail from odin and on the phone it says "only official released binaries are allowed to be flashed"
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Did you make sure you're not stuck in rmm prenormal or kg status locked?

Also does it fall while you're in odin or when you try to startup?

If it's during startup did you flash the rmm patch zip?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
How do i check if im stuck in rmm prenormal or kg status locked?

It fails after i hit start on odin...ill start it and it will get to recovery and then say fail the last script that is on odin says FAIL! (Auth)

Where do i get the rmm patch just incase i need it
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
The rmm or kg status is shown on your device screen when in odin mode.

The rmm patch is available in step 7 of the op.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
I am in the rmm prenormal status so now that i downloaded the rmm patch do i install it thru odin?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
No. Unfortunately you'll need to wait a week for prenormal status to reach normal unless you know someone with the chimera tool.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
i have already waited more than a week so i dont understand why i am still in the prenormal status
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
I really don't know to be honest. I don't understand it either.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
could i download the chimera tool myself
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
You can but it's not free and not exactly cheap.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
If i got it could u tell me how to use the tool correctly?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] KB!:
It is less than $15 for a 3 day trial of Chimera tool.

And it is very easy to use... self explanatory.

Just FYI. I had the same problem with RMM prenormal after waiting over a week and the Chimera tool had me up and running in short order.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Oh ok thanks. I didn't know how much it was.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
bruh! i did that and tried the rmm unlock and that **** failed to.... this phone just hates me! i tried just having the phone on and and doing it and also having it in download mode so at this point idk. i might be doing something wrong if theres any suggestions to try please let me know. if not ill just try resetting the phone and wait a week again and see if it works then
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
I really don't know. I've never used the chimera tool. I've never had an issue being stuck in prenormal once I got out of it the first time when I first got my phone. All I did then was wait a week for it to do it's thing.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Datkidd860:
I tried to do the rmm unlock and the kg unlock and both failed...am i suppose to be in download mode or no?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] KB!:
I don't think so but it's been a while since I did mine. I remember you plug the phone in to the PC with the Chimera tool open and it would read the phone and tell you the make and model and all the phone info and then it would give you the options available and you clicked on whatever you wanted to do and it just did it... pretty simple.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] copachono:
hi all im trying to root my SM-G9650 but i believe im making something wrong, i installa everything even de custom kernel and start normal, like new i have to install everything on the phone, but when i use the root checker it says: rooted, but in the busy box says its missing, also if i restart the phone when it boots it boots on safe mode, phone begins to heat up and restart on the same loop, so i have to reflash all again and continue.

i have also seen that i dont get the keep read only on the twrp recovery
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Your phone shouldn't be overheating just from root. Root is stable for us. BusyBox is not installed by default.

Not sure what you've done different but it shouldn't be like that.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] copachono:
Hi, maybe my problem its that i slide to install twrp app??, also i got the safetynet status failed, could it be my magisk its wrong?? where can i install busy box?? i have tried searching with no luck, the phone its stable also as long as i dont reboot it, if i reboot the phone i just crash to a safe mode stuck and keep rebooting crashing
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
They're is an app available to install BusyBox.

The twrp app doesn't matter.

Just use the latest official magisk and my kernel and you shouldn't have any issues.

Although I haven't tested 19.4 yet just to note that.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] copachono:
i had magisk 17 so im updating to 19.4, the busy box app didnt do anything before when i had the 17 version, now its rooted and verified also with the busy box installed, thanks for your nice work.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] copachono:
somehow something happen and during a restart, i got the only offical binaries message, does anybody have the stock recovery to flash?? i had the android 9 july update
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Le_MaR:
Hi, Somebody can write exact STEPS especially after TWRP in which order need to be installed zips?

Currently after doing all steps Im stuck in Samsung logo.... how much should I wait?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
The wait is typically 12-14 minutes.

The steps are exact.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] Le_MaR:
Thanks will try to wait again ))

What about steps ? I have tried like this:

1. TWRP

2. Swipe and allow modifications

3. Format Data

4. Install Kernel

5. Install RMM Bypass

6. Install Opt-encyrpt disabler

7. Install Magisk

The main questions: does install zips order is correct and should I select Keep Read only in 2.nd step and should I add another step like Reboot to Recovery between Format Data and Installing zips?

OK. Noticed that you said that steps are exact

UPDATE: WORKED in order which I wrote above.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Yes, there are different variations to which will accomplish the same goal.

If you choose, you may format data first then reboot recovery and you would not need to keep read only.

I never worry about the keep read only option because once my kernel is flashed the read only stuff doesn't matter because I remove dm-verity.

So yes, your order of flashing looks appropriate.

Just make sure to use the files in the op. Some encryption disablers aren't compatible with our system.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] MrFhenix:
there are no custom roms that I would advise using

stick to stock Roms for now.

what is happening in your case is a dirty flash

you have to Factory Wipe...

now search for samfirm on duckduckgo.com

enter your phone and type MXO this is the Latin America unbloated rom

if you have twrp installed then just full wipe. reboot

install zip.. reboot then THERE IS A 20 MINUTE time

to first reboot do not interrupt or die..?????

Hi everybody!

I have this s9+ SM-G9650 from Mexico/Telcel(carrier) and their crapware (both samsung & telcel ****) just make me mad, and decided to change the rom for a GSI Pixel experience without all that bloatware.

So, I had success following this guide <How to Install GSI ROM on ANY Android Device w/ Project Treble & Unlocked Bootloader! [TWRP Method] > (I don't know if I'm allowed to post links to other pages, I don't like the admin deletes my post :-p ).

Everything worked fine until I had to install my bank app, and it refuses to open, then I tried to hide the root on Magisk Manager without success, so, I decided to roll back to stock ROM, since this is a company's smarphone, I need it ready all the time for work, I couldn't research more on the issue.

So, I find my country/carrier stock rom in the samobile page (I didn't backup the original with TWRP, my mistake!), and using ODIN I rolled back my smartphone with success. I don't know why, but I couldn't make Magisk install on this stock rom, so, now I have a s9+ just with the stock rom installed, no TWRP, no root, and it runs well, I leave the OEM Bootloader opened.

Now I have this netflix issue due the app doesn't detect compatible valid android device, I read already a bunch of options of this, also I noticed I'm not able to use Secure Folder, I'm think is due Knox was marked with that the warranty is voided bit, I don't really care at all since this is another feature that I don't use (I just noticed), but my real problem is now I'm not allowed to get operating systems updates with this rom, the error message is attached on the image.

So, I'm worried to not receive security updates, I don't care the Knox and its features, my original goal was to have a smartphone with no bloatware and for my own toughts, I believe Knox, Dex, Bixby, telcel/claro apps/games are all s*it that don't use and they all just consume resources (Bixby services consumes 1% battery in 1 hour, even with no use and permissions/things deactivated, almost every f***in Bixby service cannot be disabled!).

So, I want to know if some one here has an original SM-G9650 TWRP/ODIN firmware backup, or if someone knows a method for restoring updates, or if some knows how to make work apps like netflix/bank on a custom rom on this smarphone specific model, since almost every thing I've found on the web referes to Exynos and chinese models. Also I would like to know recomendations for trusted roms, since I tested with this PixelExperience_Plus rom from EnesSastim (find it on github), I had it installed on my phone just about half day, I could not test really well.

I have one last question, since there's lots of years that I'm out of this mod scene, can I trust on sammobile roms¿? I had a pair of experiences in the past what makes me paranoid with the security of the operating systems on all my devices. I know it sounds like a paradox (Custom rom? what was on my mind that day? :D ), so try to help me if you are able, and not to judge me ;) ...

Thanks for reading and for your help!

Best regards!

I had very hard time getting rid if it. And even after waiting couple of times for more than a week it stayed. However what helped me is this xdaforums.com/showpost.php?p=79213477&postcount=102 (read my msgs on that pages) klabit didn't acknowledge it to have anything to do with it but i know that this was the ridiculus cure of this **** sung coding and uneeded low quality protections.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
Ok.... First, not sure about your banking app because "it doesn't work" is quite vague.

Second, you can't just install Magisk on full stock. You need my custom kernel then install Magisk.

Third, netflix doesn't work due to some crypto libs being compromised due to the unlocked bootloader and root. (There is a Magisk module that fixes this)

Fourth, Secure folder can possibly work but requires some technical work but it doesn't work for you now because of the knox fuse being tripped (0x1)

Fifth, the OTA updates will not work since you have unlocked your bootloader.

Sixth, sammobile is indeed a trusted source for official samsung firmwares. I use it all the time.

Last, sorry it took some time to respond. I have been quite busy in real life.

No idea what you think pertains to his questions/issues. lol

Those commands you refer to only log the android system and searched and showed (grep) what was defined afterwards (rlc).

Nothing more and nothing less.

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] iooxda:
Hi,

I have kind of a noob question. I have read this entire thread and I would like to install TWRP and root my phone however I am a little confused about this initial point:

BUGS:

- Samsung encryption is NOT supported

Does this mean that after installing TWRP, rooting and installing the custom kernel I cannot use the device encryption afterwards at all? I think Samsung calls it "Secure Startup" or isklabit87 referring to the fact that you cannot install TWRP while the device is already encrypted? Basically I would like to know that if I root my device using this method does that mean I will not be able to use the device encryption features at all going forward.

Also, what about the SD card encryption would this feature work as well after I have gone though the process in this thread?

Thanks.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] klabit87:
You can use encryption but twrp can not decrypt it for use while in recovery. So for instance, if internal storage is encrypted then it will only show as internal storage 0mb because it cannot mount the encrypted partition.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] iooxda:
Okay, so I will wipe everything, start clean, install twrp, su etc.

When I am finished I will be able to turn on drive encryption with the new kernel correct?

What about Samsung Knox, would I be able to use Secure Folder afterwards or is that completely gone?
