Boot stuck on samsung galaxy tabs s2 - Galaxy Tab S2 Q&A, Help & Troubleshooting

Tried to install xposed framework on Samsung galaxy tab s2. I was following a tutorial that had linked downloads. After the install the boot just freezes at the Samsung logo.
After a little research I found there official thread http://forum.xda-developers.com/showthread.php?t=3034811 which mentions there is a problem with Samsung stock roms and bootloops. I wouldn't say my problem is a loop but it is probably related.
Anyway, I would love to just go back to a stock rom start all over. Don't really care about losing anything at this point. I think I got the official rom but when I try and flash it with oden it fails. I get this error on my devices screen "SW REV. Check Fail. Device: 2 , Binary: 1"
Anyone familiar with this. I cant seem to get around it. I have gone into custom recovery and did a wipe. but that's about all I know to try.
thanks.

You need to install a revision 2 firmware, you are trying to backwards install revision 1.
Revision 2 will have XXU2 in the build number.

You did enable OEM Unlocking, right?

Unfortunately you can't downgrade. Once you have flashed a higher bootloader version you are stuck with it.
If you are on bootloader v5 you may be able to downgrade to the last Oreo build, I am not 100% sure on that though.
Only if they are same bootloader

No, there is not, sorry
Ok. So the final note is that i am not able to downgrade... so let me help with other issue that might help me. Knox on my device is tripped so i cant use latest samsung health app. Earlier on oreo i was able to install older version of app and then update it. But now on pie. Older version is not installing. It always says apk not installed. Atleast help me with that

You need to be rooted to be able to get that working again, some roms also have that patched already...
Although the thread is about the s7 I believe it is exactly the same for our note 8.

I dont want to root again.... rooting will not let banking apps work.moreover if i wanted to root. Root files for note 8 pie are not available right now. I installed patched app but it does not have heart rate monitor and spo2 which renders heart rate sensor useless.... thats why i am so desperate for that app

You can flash TWRP, copy /system/build.prop to the PC or SD Card, edit it on the PC, put it back in /system.
Once you are done, just flash stock revovery via TWRP.
It sounds hard, but it's eazy if you know what you are doing. Banking apps will still work, and with build.prop edited s health will work too.
I am not gonna walk you trough the entire process but this is a summary.

Oooh that, it's nothin.
You just need to hold volume up + bixby and power just before the phone auto restarts from download mode. When you do that it will boot twrp.
If you don't understand it go watch MaxLee on youtube, his method of flashing twrp on s8/n8

The way I know it, there is no way without twrp or root, and you said you don't want root because of banking apps.
If you flash twrp, do the thing with build.prop, and then flash stock recovery, you could still recive OTA updates and banking apps will work.
You just have to set up s health before the next OTA because that will revert built.prop back to normal.
But as long as you set up s health before that it will be ok.

The reason you can't install the modded version is because the version that was modded is less than pre-installed version on the device. As of now, you can't downgrade apps, only upgrade. Your only option is to wait for someone to patch a later version from the version you got installed on your phone.
I think someone can even just change a number in AndroidManifest.xml install it and then just upgrade.
I'm sure a patched version will pop-up again somewhere on xda, just make sure it's later version than the version pre-installed into the system.

Which official firmware should I download for my Note 9?

Hi everyone,
I bought a Note 9 a few days ago and its rooted. It has got Android 9 One UI 1.0
I wanted to update the software but it has no software update option.
So I thought maybe I can download the latest software on it through odin.
It is N950F model. On settings, it has the following baseband version: N960FXXU2ZRLR
SE for Android status is showing the following: Enforcing SEPF_SM_N960F_P03_Dr.KetanROM
And bootloader is showing something like this: N960NKSU3CSG3
Now I'm really confused that which firmware should I download?
Can anyone help?
I would recommend that you download and install android 10 to your Note 9.

Use 'samsung phone info' in playstore. Check which csc the phone originally. Download that csc's firmware and flash.
By right any firmware should do but who knows.

once rooted you will lose knox protection, secure folder Samsung health and yes oem updates. even if you flash official again you may receive oem updates but some oem features may not function again. so u might have two options here. one is to re flash via odin the official firmware and use the phone without some features as i mentioned above! also now that our beloved note 9 got the final 2.1 major firmware update it is highly unlikely to get anymore upgrades such as oneui 2.5 but will continue to receive monthly security updates! then the second option is we have some great devs like dr.ketan, AlexisXDA, etc with highly customized roms and many workarounds to get features like S-health and secure folder working and they do keep upgrading the roms and we might even expect to get oneui 2.5 features from them which is excellent. i too am still on stock rom not even rooted but will start having fun flashing roms after my warranty expires for sure! cheers

[samsung note 8][revert to stock firmware from custom]

Alirghty so i bought a used samsung note 8 duos. it says it on the back, in the software, in smart switch, heck even the AP and CSC files are infact for a SM-N950F
Here is where the problem is as far as I've figured out, I'll explain what the firmware files are on the device taken from dialing *#12580*369#:
BL:N950NKSU5DSK1
AP:N950FXXS7DSH1
CP:N950NKOU5DSH1
CSC:N950FOXM7DSG1
The phone runs fine honestly but its bugs me that there two different binaries mixed in my phone from what i can tell the BL and CP are from a Korean level 5 Binary (also can someone tell me why security levels matter now?) and the AP and CSC are from F model level 7 Binary
I cant flash anything stock cause its the only thing ive tried and it just wont let me. I am downloading a level 5 binary in *hopes* that it doesnt see an issue with the security levels between firmwares as i always get the fricken PIT error or secure download error orrrr the magic string invaild
All i need is a way to get my dualsims back up and running ive got two imeis on this phone which ive checked online and theyre working also id love it if i could just get all 4 files to be from the same firmware zip
FYI the only thing ive been able to flash is TWRP after which i got to installing no-verity and magisk, Ive been using twrp backups as a failsafe to revert back to the 'original' state my phone was in and thats the only thing working for me so far and i may or may not be a noob in flashing samsung devices

The reason for that is because the phone has obviously been repaired using different hardware from different devices. It's never going to be able to flash normal firmware being that there's different hardware in it. If you want to upgrade that you'll need to use the different versions of firmware for each different hardware.. I'd just send it back if I bought it from somewhere like that.
Revert to Stock
I owns one Galaxy Note 8 SN950-F Indian version,
I have installed one custom ROM for my mobile last month and now i need to revert back to stock.
How can i do it ? Once i installed stock OS using Odin but Knox looks crashed and apps like secure folder not working !
Can i get it done through service center ? When i contacted them they said its impossible as you have rooted once.

Once Knox is tripped it takes a motherboard replacement to revert it.
If SF (Secure Folder) is that important to you, stay on a custom rom that has patched SF patched already.
Literally all TWRP/Rom threads warn you of this, always read the whole OP of any thread in the future.
Yeah. Thats what im doing now. Running on doctor ketans rom.
but im little worried now. Because haven't used any custom roms and worried about security issues.
Can we still go back to stock os ? With genuine updates?

Like I said to you above, once Knox is tripped SF won't work, if SF is that important to you stay on a custom rom that has patched SF. If you're worried about security updates use DeluxeRom which has last months security patch.

I am having this same problem.....my phone got bricked so i was looking for my stock rom but the only stock rom that works with my Samsung note 8 is the korean version which supports one 1 sim but my device is dual sim

Good source for firmwares?

I'm looking for a good source of firmwares, i know the famous sites but some firmwares doesn't seem to be listed. I know in the time os Samsung KIES there were tools which communicated directly with samsung.
For example these firmware builds for the SM-G975Ux aren't listed on most firmware sites but have the December secutiry update with binary/bootloader version 8: G975USQS8IVL1 and G975USQS8IVL2
All the big sites have ROMs for that phone (same one I have). There is no "Ux" model... it's *U or *U1, with the latter being unlocked. IF you search for U1 ROMs you have many selections, but most get the XAA version which will usually change carriers automatically based on the SIM card.
The latest BL=8 version I see there is https://www.sammobile.com/samsung/g...M-G975U1/XAA/download/G975U1UEU8IWB6/1741280/ which is the February 2023 security update. I believe this is the last one we are getting (but I could be mistaken as there may be 1 more security patch, I don't remember).
There's U U1 0 W F N .... I'm looking for the oldest firmware with binary version 8, but it seems the sites don't show all firmwares available.... i'm looking for the oldest firmware with U8 bootloader (or any compatible bootloader with binary 8 version), i could have a look at all sites and try my luck... but they don't seem to have all data. but like i said i prefer some original source xml files... i saw some url's to original samsung servers but can't find them anymore.
There is already a firmware available with the march update.... but you have to be lucky to find them... i'm looking for original sources. like update.zip's and such
Found the first one....
https://fota-cloud-dn.ospserver.net/firmware/TMB/SM-G975U/version.xml
I'd recommend around sammobile and samfw. These are the two sources I use the most

if i flash a new rom (whether original or custom rom) nothing happens after the reboot... download mode works too, flashing twrp works too! however, the system boot does not work via twrp either... not even a bootloop, the cell phone does not react at all! the task combination for
Right now I don't even care if I get the original firmware or a custom rom running... I hope I didn't brick it (((
My old device was a G930F, its unbreakable make sure you flash the right rom and wipe data and dalvik cache after flashing.... THis ons is locked so it doesn't have fastboot. My G-930F came with fastboot enabled so you can always fastboot a recovery.img. like TWRP
Did you try to download TWRP from twrp.me and "fastboot boot twrp-3.7.0_9-0-herolte.img" ? it should boot to twrp in fastboot mode (hold volume down + home + power).

1. is your KG status is broken?
2. Is your bootloader unlocked?
You know how to flash lineageos through twrp right? and how to use odin?
Maybe flash lineageos to see if everything works.... and then revert to original software. Be sure to wipe cache/dalvik and userdata

There's U U1 0 W F N .... I'm looking for the oldest firmware with binary version 8, but it seems the sites don't show all firmwares available.... i'm looking for the oldest firmware with U8 bootloader (or any compatible bootloader with binary 8 version), i could have a look at all sites and try my luck... but they don't seem to have all data. but like i said i prefer some original source xml files... i saw some url's to original samsung servers but can't find them anymore.
There is already a firmware available with the march update.... but you have to be lucky to find them... i'm looking for original sources. like update.zip's and such
Found the first one....

Yes, I know there are many other variant firmwares out there, but for a U phone (snapdragon) there is really only U and U1... the rest are incompatible.
There is no "older" firmware with binary 8, because the firmwares are packaged with the proper/compatible binary already. Basically, the "binary" is the bootloader version. On Snapdragon phones, you must have the proper BL/binary to flash, as you already know. You can't interchange the binary/BL with the ROM and security updates because they are not made that way.
The update.zip you're looking for are updates sent by Samsung directly, and they can update the ROM (and Binary) from one stock version to another... but, again, they will update both the binary/BL as well as the ROM, so they can't be broken up to only do one or the other.
It sounds like you're trying to get to an older ROM version (for whatever reason) with an older security patch level as well? Basically, this cannot be done on Snapdragon phones. Once you're on an updated binary/BL, you're stuck there (at least today you are).

I solved the problem! I had unlocked the bootloader, but I also had to deactivate verity via CMD with twrp+adb "adb disable-verity"
ok i've solved the problem now, but does anyone know why i couldn't even start the original stock roms? Actually, the stock ROM should set everything to factory settings...

Thank you for helping so quickly with ideas... I would not have expected such quick help with such an old model, even samsung customer service didn't want to help me yesterday

I've tried different firmwares, its all about snapdragon. You can also flash SM-G975W parts and other snapdragon variants.... there's a lot of variants out there.
I first upgraded and then downgraded to the parts i wanted and am on a rom now with security patch level December 2022, as long as the binary version is the same there's no problem. I've got the latest modem installed and the oldest firmare and bootloader for the latest binary version, i can upgrade or downgrade my bootloader. I already asked someone before if this was possible and if he could confirm because before i was only able to flash CSC and AP i think.
If there's no updates comming anymore why not downgrade and wait for a new leak
I'm also sure we can unlock the bootloader, i'm trying to make an lposed module. I've installed lspatch and lposed and they work fine for some modules. The bootloader unlock has several prerequisites (properties and such) if i can make it look for other properties or something like that we might get an unlock option. Also it looks for an encrypted file on EFS, if someone with an unlocked samsung phone could copy that file we would be a lot further.
It's called /efs/sec_efs/sktdm_mem/encmembership.txt and should be an encrypted file, also if anyone knows how to set ro properties without root (like a stub before the preference controller starts) this would be very usefull.
