Generally speaking: Install bootloader only with Odin.
You should now flash firmware using Odin to save your device. Maybe Kies could restore also.

HERE you may find firmware for your country/device, download.
Start Odin, connect your phone in download mode to pc, see if Odin shows up com-port and flash firmware in tab PDA/AP.
There are several guides on youtube/google

Cant Find my carrier
my carrier is international, only countries are on that list, I dont know which one to choose, also if im gonna flash firmware is it possible to flash 4.1.2? or 4.2.2/4.3?

Depends on your last firmware. What was the bootloader version? If above MJ5, you can't downgrade so you are free to flash eg latest 4.4.2

The MJ5 bootloader, i found one that said it would be flashable through a recovery menu

1. Never flash bootloader through recovery
2. I assume that you have had newer bootloader than MJ5 before flash, so you soft bricked your device
3. To regain full funtional device follow post #4

Original Recovery

Hi Guys!
I switched to TWRP and did not backup the original recovery. Is there any way to get the original file and install over twrp to go back to stock? I use the Tab S-10.5 LTE if that does matter?
Thanks a lot!

Easiest way is to flash cf-autroot, it will replace recovery with stock. It will also root your device. To remove root just open the Super su app and select Full unroot from the settings.

Thanks a lot!
I will try it tomorrow

Hi Guys!
I still havent solved the problem! I cant install cf Autoroot! I have no idea why. I'd like to go back to a full stock device. Please do not argue with me about it.. i just like to do so
I'd really appriciate it if someone can provide me the original recovery (or is it the bootloader that twrp is?! - I dont know...). But the original file so I can go back to stock. I really tried to search for it on the web, but i really can´
t find it.
Thanks a lot! :fingers-crossed:

What do you mean you can't flash cfautoroot? Did you use the right one for your device?
You can pull the recovery image from any stock Rom. Just flash it with twrp using the image flash option or just flash the whole Rom.

Thanks!
I will try it!
I really dont know! I defnitly used the right cf autoroot file. But when i try to flash it, odin gets stuck in "setup connection"... It's stuck there until odin stops and shows the "fail" error massage?!
I use Windows and startet odin as administrator.

Do you get the added message? I take it you have extracted the tar file from the zip and not attempting to flash the zip directly?

Yes..Odin shows added..AND I extracted the tar file.
Really i have no idea what the problem is. I also made shure to use the right cf autoroot file...I don't know...
Since i can flash nearly everything else with success i dont think that i make a mistake

Do you have reactivation lock enabled?

I have absolutly no idea what you mean...could be a step forward

You should always always backup every partition. Especially efs.
Anyhow, what service are you trying to use? GSM or CDMA?
If your using it with GSM, and If this phone is truly a sprint phone, it probably got sim locked when he fixed it. I ain't no expert but it probably needs unlocked if this is the case.
Edit: I just understood what you wrote, that he already unlocked it. Sorry for misunderstanding.
But if your using it with sprint, maybe it just needs activation updated. I don't use sprint or CDMA so I don't know a lot about that.
But main thing you need to do before anything else. Is make a full back up of your partitions. I always make backup in two.( Which is mainly all you need)
But also there are programs that (I can't remember there names,) make backups of all your hidden partitions, just in case.
I understand I didn't provide you with a definite answer to your problem but hope it can help.

Can to send me a copy of your build.prop
Edit. Are you using sprint stock ROM? What version? Are you sure it's unlocked? If yes, I might be able to help. But I have to gather some info. And get to my PC. Cause I'm testing a ROM right now and am lagging

I have faced the same problem and, managed to solve it. Here is the solution..
1. Download any kk or lp firmware of n910p. Extract the .tar file, get the ' modem.bin' and flash it using Odin. Do it twice, yes, twice. Before flashing the modem, make sure you have unchecked 'auto boot' option in Odin. To turn off the phone after the first flesh, just take off the battery.
2. Download twrp 3.0.1.0 for n910f. Yes.. TWRP recovery for N910F ( or the model specified under the battery). Flash it using Odin.
3. Download any stock based custom ROM which is based on the modem you have flashed. For example, BOB7, COG5 , COK1( these are the last 4 characters of the stock firmware/modem)
4. Flash the custom ROM using twrp, flash gasps, and smile.
If you face bootloop, just try different kernel. I'm using BOB7 modem, emotion kernel, vision x custom ROM.

yes i am sure phone is unlocked through Domestic Unlock ( z3x & octoplus Boxes)
also i am on Stock 5.1.1 lollipop
I think the only way u can help me is by sharing a good QCN and EFS for N910P ! (if the above solution from our friend doesnt work 4 me )
Also i am from another country so there is no harm for you if u share it with me in private.
Thanks in Advance !

No I'm in the United States look in the zip options and when it says to zip the img file look to see if it has a option to zip it in a tar format also beware that there's a big chance sadly that it won't flash cause you don't have OEM unlocked enabled in the the developer settings of your S9
PoochyXXX

Thanks really If i can't flash by twrp? how can i do after? yes OEM IS LOCK ALSO FRP ? ;-(

I'm assuming your flash counter in download Mode is on 0 if it is you could still be eligible for a exchange

S9 soft updates problem

Hi
I've problem with my sm-g960f. I live in UK, but my phone was bought in Switzerland and because of that I am not receiving any system updates. Samsung support told me to go to Switzerland to check if I'll receive update there, but it is not an option. I've got stuck at android 8.0. Is there any chance that I update it manually to newest one? If it is, please help me with it. Thanks!
I've never did anything with phones soft before, sorry if it is stupid question.

When I was like you I did a lot of research for what i needed to flash the software i wanted and what to do if any thing goes wrong.
First you need to unlock your bootloader and this can take 7 days to confirm and also wipes your data. Once unlocked you need to flash twrp through Odin on your pc also you will need a file to flash to stop a boot loop after flashing twrp. Then you need to download the latest firmware from Sam mobile, this can take hours on the free account. Then use Odin again to flash the firmware android 10. Then you will be updated

You don't need to flash TWRP, for this to work. You can do it normally using stock recovery.

Start from this step. I highly recommend to download original firmware using the Frija tool (search here in XDA) because there you don't have any limiting download speed. Once downloaded, you can now just go to stock recovery, wipe data, cache and system, and reboot to download mode and flash the downloaded firmware from frija tool.
