Unrooting without losing data? - T-Mobile Samsung Galaxy S7 Edge Questions & Answer

Hi I was curious would it be possible for me to just flash the bootloader from the current Tmobile firmware after Unrooting? Or do I have to clear everything and flash the rom as a whole? I'm just on stock.

Thanks for the help guys... ?

Sorry no one replied... FWIW I tar'd a stock boot.img from the factory APK1 firmware and tried to just flash that in Odin to replace the engboot kernel... and I got the dm-verity fail message in recovery when the phone rebooted. it's possible I did something wrong or maybe i should've tried wiping data/cache after that but I just ending up flashing the entire firmware in Odin again.
Good luck!

Wow.
Okay then. You're welcome.
Seriously, who here is paid to answer your questions?
We owe you nothing so lose the attitude please. It wasn't until just now that I even saw your thread and although I could easily answer your question, I'm feeling even less obliged to do so now.
You need to be patient! Otherwise, call Samsung and ask them for help.

Yeah, that wouldn't work since the the /system partition was modified for superuser. It wouldn't be as easy as flashing the boot.img from stock.
You have to do the entire AP.

[Q] [Noob-Q] If i flash a stock firmware through Odin would it erase my data?

So guys a noob question here: If i flash a stock firmware through Odin would it erase my data? Or would it work like Kies or OTA?
A one part/single file firmware shouldn't (I did this two nights ago & it didn't), if you flash a 3 part firmware w/CSC it will.

stock firmware for s4 come usualy with a single pda package to put in odin.
it wont delete your data.
but i strongly recommend to backup your data to your pc before flashing in case you need to wipe the device after flashing if it stuck in a bootloop

Well essentially. ...data doesn't get deleted...but there are some instances that...when you flash an odin stock firmware...the phone will start up and get stuck on the boot screen ....in those instances...you need to boot into the recoveey mode and clear all user data....that will definitely delete all your files in the internal memory. ..so back it up...and proceed

[Solved]Need help after formatting internal storage! Soft Brick

I truly need the community's help on this one. Trying to fix a rom that I was using, I decided to wipe everything to reflash it. However, some how I read the thread wrong. Using TWRP, I formatted the "internal storage" thinking that was going to fix my Rom problems.
Now, I can't boot into the Rom or any rom, unless I wipe everything and restore one of my back ups. I restored a back up and it booted, but my data is jacked and phone service is not operable. I thought maybe a reboot will fix it, and now my phone is stuck at "Samsung Galaxy S 4". It doesn't move from there.
What should I do? How do I get it it continue the boot into the rom after a regular reboot? How do I get my radio back?
It's funny to me because I usually never get this careless with my phone. So I can laugh about it but damn I have to figure this one out!
Please help!!!!!!!!!!!!!!!!!
I am by know means an expert but I think you may have to start here with the firmware files then try and flash your backup http://forum.xda-developers.com/showthread.php?t=2338919

Thanks Chief, let me try that!
Thanks Chief. Unfortunately, that didn't work. I used Odin to flash the Firmware files and let it reboot. I'm still stuck at the Samsung Gal...boot screen. Let me try manually going into recovery and restoring.
Any other ideas? Anyone?

Have you tried flashing the complete odin ROM? You can find the all in one somewhere on the dev thread, it has rom, kernel, firmware and the rom all in one as it came from samsung. That should take care of your problem. It will wipe everything, or I think there was also a thread somewhere with odin flashables that didn't wipe data or internal sd but I can't seem to find it right now.

Exactly. I'm on the target. I'm currently waiting for this tar that will unroot the phone. It is MDL but I will update and reroot. I hope this does the ticket. I'm going to use Odin to flash it or unroot.
Well strike two. That didn't work either. I downloaded a unrooted MDL tar and connected to Odin. When through the entire process and it rebooted. It still is stuck at "Samsung Galaxy S4".
I read on the Nexus 7 that I might have to reflash a system.img and boot.img? Someone else had a similar experience on the N7 and had to download it via flashdrive and then install via recovery. I'm not saying that's the case but I wonder if I need to reflash a boot.img or something.
Please help. Not sure where to go at this point. Unrooting didn't help.
Try downloading this file extract the tar and flash that in PC Odin. (don't check repartion!).
That is the full stock MF9 firmware, boot, recovery, kernel and ROM.
Then maybe use CF Autoroot, then goomanger to get twrp and flash one of your nand's
Progress made.

leader, chief, ifly4,...I'm making progress.
leader, actually I flashed a previous version, the MDL via Odin. At first it didn't boot as stated in my previous post. I decided to wipe and factory reset. """"Bingo"""" it booted. Now I'm on MDL and unrooted. However, I transferred my phone over to a previous device so I can't update profile and prl. I'm going to activate the phone and see if it works. For some reason I can't can't seem to get a radio signal on it. It shows the be O with the slash in the middle. This is what it looked like before I deactivated it and lost everything before.
I post back with results. Not quite solved yet.
Thanks leader and everyone else.
Sound like your on the wrong firmware/baseband. what does your modem/baseband say?
Yeeessssss

It says L720VPUAMDL. I actually got it going. I had to change it from WCDMA to CDMA and reset. Now I'm unrooted. and going. However, leader, is there away to update the modem/baseband before I root? Or should I root then flash the MF9 Modem?
if you got MDL to activate you can jst take the OTA update to MF9. It will update it all.
Then use CF-Autoroot to gain root. After that same - install goomanager from Playstore and use it to install TWRP.

Awesome. Hey thanks again leader for helping me out. I'm usually never careless with these things. I use SACS rom but decided to try Miui. From some reason every time I flash Miui, I get the "Roaming Indicator Off" thing along with two signals. Reading the thread it suggest to format the internal. Why oh Why did I try that step. The rest is history....
Thanks again. Learned a lot with this process.
Glad you got it working.

Looking for stock recovery for i9515

Hello,
I am looking for the stock recovery for the i9515.
Or can I just use the i9505 stock recovery for it?
Thanks in advance!

I would only ever use the suggested recovery options, NEVER use a different model in your phone.
http://www.sammobile.com/firmwares/
Click that link, type in the "Find device" search box and input GT-i9515 and you actually get a lot of stock roms. Because it's from Samsung it is all official. You will need to find Odin 3.09 and a helpful guide to aid in the procedure, all current information will be lost on your device and will bring it back to stock (except perhaps the flash counter, which can be reset with Triangle Away)
As always, do as much research as you can before going ahead with any potentially dangerous changes!
Good luck

I actually did use a CWM recovery option that wasn't specifically for the i9515 but for the 9500 or the 9505. I do not remember which one of both of these I did use though and I do not want to take that risk again.
So this will also reset my ROM and wipe all data? That is not what I am looking for unfortunately. I am looking for solely the stock recovery menu. Everything else should stay as it is. Isn't that possible?

As far as I'm aware the only solution to remove the Custom Recoveries is to flash stock firmware via Odin, I could be wrong but I've never heard of it.
Sorry I can't help further, best of luck with your predicament.

No it will not wipe your device. Just pick the stock rom that is for your device.

Just flash the stock rom
"If someone helps, never forget to hit thanks ? "
I can't flash the stock rom because I want to keep a modified rom and yet still have the stock recovery.
If you care why: Cerberus anti-theft rom.
So I need a way to keep everything but the recovery. That one has to go back to stock so no thiefs suspect custom roms when doing a hard reset and seeing CWM Recovery.
Bump
Bump,
no one got an idea?
Well then just download the official firmware and extract recovery.img. Then flash it using terminal or heimdall.

I gotta be really stupid or I am overseeing something.
I got the whole 1,6gb firmware.
It has this file in it: "I9515XXU1ANI2_I9515VFG1ANI1_I9515XXU1ANI2_HOME.tar.md5" I tried changing the .md5 to .zip but it only showed me a few files inside it then that did not include a recovery file. Emulating the .md5 file with daemon tools didn't work either.
I don't know how to find the recovery file in it.

Hi
Rename your .md5 firmware in .tar, then open it with winrar, and extract the kernel called "boot.img".
Then flash it with "mobile odin" in your phone.
Hey,
thanks for your help, but there is also a recovery.img. I guess I will flash that one and not the boot.img one if I want to have the stock Recovery, shouldn't I?

correct.
Alright then, wish me luck, I will try it this evening.
Edit: already did it quickly. Worked perfect! Now I have the stock Recovery back and just the Cerberus ROM installed. Perfect. May these thieves come if they dare... They won't realize at all that there is something integrated in this ROM.
I used RashR by the way.

[Solved] Recovering data from stock bootloop

Hey everyone,
Apologise for asking this question ! As it has been covered before from my research but not exactly and I am still quite confused so I'd greatly appreciate some insight from you guys.
Basically I have a stock i9505 which has gone into bootloop, it is not rooted and not modded in any way.
I've tried to enter recovery mode and wipe cache partition but it did not work, so I can do a factory reset, but a factory reset with stock recovery will wipe all of my data off my internal SD card.
I have downloaded odin but there a few different opinions as to what I should be doing, some threads say I should install CWM and run ADB to fetch the files. (https://forum.xda-developers.com/showthread.php?t=2498228&page=2)
Another opinion is that I should use Odin to flash a stock rom
"Install a stock ROM through Odin, as Odin doesn't wipe user data when a ROM is installed. If you want to play it safe however, install TWRP first and make a nandroid backup onto your MicroSD card. Then install the stock ROM."
(From this thread https://forum.xda-developers.com/galaxy-s4/help/recover-data-soft-bricked-s4-i9505-t3236351)
Would someone be able to point me toward the correct process for recovering my files? I will appreciate it immensely.
Thanks very much!

It is the UK unlocked LTE version. I think the version number currently on the phone is i9505xxuhoj2 . However every place I have tried to DL from is one of those sites where you must sign up or it gives you an impractically low speed (sporadic connection means it cuts off the download quite quickly).

Help recovering back to stock ODIN Flash Fail!

First of all let me say that I appreciate any help you guys can give me.
So I was trying to unlock to bootloader on my phone from KitKat 4.4.2 (NCG)
I was impatient and did something stupid.
I flashed the G900V_Firmware_PB1.tar.md5 file with Odin and repartitioned with the PIT file.
Of course it didn't work... Annnnnd I bricked... (Softbrick).
So after trying a few other things to no avail I panicked and booted into Stock Recovery Mode and did a full wipe/factory reset, wiped cache, then booted back into DL Mode and TRIED to flash the stock firmware to start over. The problem is the ODIN flash keeps failing and I don't know what to do.
I tried downloading the Stock Firmware from multiple sources and it keeps failing.
So I'm starting to freak out a little.
I can still successfully flash the G900V_Firmware_PB1.tar.md5 but that doesn't help me.
Any Help?

@Bren123, I've passed this to @stang5litre earlier today and not sure if hes gotten with the user yet. What do you think he needs to do? I mentioned to the user via PM that he needs to do a backup of everything, which is including a Nandroid but didn't mention if did or didn't. If so, should try that first? Should've just unlocked the bootloader first with what ROM it's currently using and then go from there to update.....hadn't had time to get back to them....not home yet. Appreciate it guys!!

Well to be honest I would just go to BPB1 here is the BPB1 Stock tar for odin (different than the one your using) https://www.androidfilehost.com/?fid=24438995911970571
And use this pit https://www.androidfilehost.com/?fid=24052804347765167 in the pit slot in odin could be in the options on the left
And flash then report back any errors if odin gives one
