Hi!
You read the topic, I will tell you what happened.
I rooted my phone (Galaxy W - original DBT sales code with I8150XXLA2_I8150DBTKJ1_I8150XXKL3), it was a little tricky.
Originaly it had the LA2 Stock Firmware on it and I had to flash a lower firmware (I8150XXKL3_OXXKL2_XEU) on it. After this I could root my phone.
OK. I played a little bit around and the biggest mistake (i think) - for me - was to test the [ROM] GingerICE 1.0 (Android 2.3.6, Custom .35 Kernell).
After I did my phones language was malaysian I think. I could turn it to English but I didn't like the FW and I only wanted to test it.
The next thing I did was to flash a stock Firmware (again the I8150XXKL3_OXXKL2_XEU), a strange thing was that in the telefon infos the phone was not mentioned as root, but it wasn't really unrooted.
When I connect to KIES it says my phone is incompatible and can't be updated.
If I try to select the sales code via the *#272*IMEI# combination there is only XEU, the original DBT (for germany) is gone. There are 10 or more others to choose, but not DBT.
So I really wanted to unroot and put a stock firmware on it to give it a rebirth and get it as it was as I got it. (or 99% percent as I got it)
First I used the DooMLoRD_v1_UNROOTING tool, it went through everything fine (I read everythng in the DOS Box) and suceeded, but the phone was NOT unrooted! There was no superuser, but it is STILL ROOTED.
Then I tried the unroot.zip file.
I first rooted it again, to have the CWM recovery and after that I turned the Samsung into recovery mode and choose the unroot.zip from the recovery menu and - surprise - it is STILL ROOTED!
I can't believe it. People have problems to get their device rooted, I have problems to unroot mine.
The best thing would be a reset to sales code DBT and any stock firmware - don't matter how old.
Are there any ideas what I can do?
I wanted to post it in the development section but I have to write 10 posts first.
If someone could help me you would make me really happy!!

Hi,
my solution would be:
1. Backup everything manually what you can!
2. Flash via ODIN ClockWorkMod Recovery on your device(english). Scroll down to other and select ClockWorkMod.
If you prefer a german instruction. Runterscrollen zu Sonstiges ;-)
3. Once ClockWorkMod is flashed, go to the recovery:
a) backup and restore -> backup to external sdcard
b) backup and restore -> restore from external sdcard
This is to make sure the files aren't corrupted, if this is successful you can be sure everything is backupped. If you get a MD5 mismatch something went wrong. Try again!
c) wipe data/factory reset -> confirm
d) wipe cache partition -> confirm
e) mounts and storage -> format system -> confirm
f) mounts and storage -> format cache -> confirm
g) mounts and storage -> format data -> confirm
4. You restart your phone in Download Mode and flash the german DBT firmware using this instruction, which is provided in the thread under Firmwares.
If you prefer a german instruction.
5. Now you will have to flash again the ClockWorkMod recovery to restore your data.
Than open ClockWorkMod Recovery and:
backup and restore-> advanced restore from external sdcard -> select the backup -> Restore data -> confirm.
Now if you want the stock recovery back(needed for OTA updates) instood of ClockWorkMod, than go to the Others or Sonstiges and select the stock recovery, and flash it on your device.
6. Now you should have a fresh and unrooted device like you have never rooted/flashed!!!
Oh yeah, the reason why you have to make these complicated steps: Because you were flashing all different kinds of firmwares, you system will be a mess. To make sure your device is not a overwritten old firmware these steps are necessary.
Flashing via ODIN does not delete all old data !!!

Hi!
I just read your answer. Thanks A LOT for this step by step answer.
I will try this, but I can't do it this evening, but as soon I did it I will post if it was sucessfull.
I am from Germany - you seem to be from germany too?
I think there a lot of smartphone/computer "freaks" from germany in boards all around the globe!
Anyway, my english isn't perfect but good enough to read instructions and follow these.
Again thanks a lot,

But it is important to make a backup on your physical sd card. ClockWorkMod does not backup the SD card.
But if you ask me, it is not necessary to format the sd card(internal). External sd is anyway not required to format.
And yes I am from Deutschland :-D If you have problems with my explainations, just PM me, I will answer you in german.

Hi!
1st - Sorry for the late answer. I am a little lazy in writing.
Everything is fine now! My Samsung W is absolutely unrooted.
When I use the *272... combination it gives me no choice, there is only DBT and this is - at the moment - exactly what I wanted to have.
I had wiped the handy and the cache before and it didn't worked well, but after I did the things you wrote "format/mounts and storage..." it finally worked!
Thanks again, I will 100% percent keep on flashing, but it is a little different with the galaxy W. I had the SGS2 before and there were dozens of ROMS and it was no problem to change anything in the phone, there was a solution for everything.
I'll give the Galaxy W a little time, until then I love my Phone as it is.
I didn't want such a big phone anymore, it is just tooo big, so I stepped down to the W.
Have a nice evening,
CU

Hi in performance terms the SGS2 is much superior than the galaxy W? Besides the screen size.
I just entered the world of a rooted phone, all exciting and new. I used triangle away, and everything is well. I even turned off the debugging mode as i thought i was all done with things rooting and didn't need it.
The next day I realize there is update for supersu, so i accept, if gives me two choices in the update, i choose one, and now my phone is the in GTN7100 loop non stop. Seems of the two options, I choose wrongly. I can put it into download mode. I think I can put it into recovery mode too.
I used this method to boot.
galaxy-note2.wonderhowto.com/how-to/root-your-samsung-galaxy-note-2-using-odin-for-windows-so-easy-your-grandma-can-do-it-0146884
I did perform some basic backups with kies and i believe an app called my backup, so in the worst case, I believe i can recover everything if had to do some kind of reset that would erase all the data. (I am hoping to avoid that, as the recovery may be a learning process if any challenges with it)
its with 4.1.2 and I am not sure if any other details I should provide. so i feel proud i got this far, sad the supersu update made some kind of corruption. i know you guys may be extremely busy and i thank you so much in advance.
Try getting into recovery (CMW or Philz touch) and re-flash a ROM?
thank you bunglebp

Thank you so much for your reply bunglebp.
I believe I had the CMW when i rooted. Reflashing the ROM won't lose the data, or will? This is new territory for me, so I am going step be step.
Volume up - home - power, i think i understand this far. I just don't want to make any mistakes and follow to a T to bring the phone back up with least work at it if possible.

Yes your description of how to get into recovery is correct. But your description of your situation is light on details, hard to get a clear picture, but I feel your pain!
If you have a ROM sitting on your phone that you can reflash in recovery, do it. You won't lose any media on your internal memory e.g. pictured, movies. All your app settings will remain if you don't wipe anything in recovery prior to flashing - but in your situation I suggest a full wipe & reset to (hopefully) clear out any problems.
As for upgrading SU, I'm wondering what you mean by two options? Let us know how you get on. Also feel free to PM me if you're truly stuck, I've been there myself and received help that saved me untold stress.

When I was welcomed to update supersu, it had a left choice (normal) and a right side choice cwm/twrp (not sure the spelling) I choose the right.
I really want to first thank you so so much.
Which options within the recovery should i choose?
When I did try to repeat the original root process, I got a PIT message that just stayed and did not change. I was on slow machine, but I think it was because the debug usb was off or as i was starting to hear, the partition might be changed in the rooting process? Not sure how that would relate. likely because the debug was off
The pain and fear that broke the phone is really intense. Plus, I use it all the time, before this happened. what information do you need?

My assumptions are you were successfully rooted, I'm unsure if you are on stock ROM or custom ROM, you updated SU and ended up in bootloop. You are able to get into recovery - do you have a ROM already sitting on your phone, that you can flash/install? If yes, do that. But first, in recovery look for options named factory reset, do that. You suggested you have CWM recovery - there is option to wipe cache, then under advanced option, is wipe dalvik cache, do those. I hope I adequately described the menu structure, my phone is not with me right now to check.
Really, we just want to get you back into a functioning ROM, and stop the bootloops. As for updating SU, I assume you tried updating from recovery? If so, stick to the Play Store updates only.
Again lemme know how you get on, and confirm my assumptions so I can help further if needed.

[If you don't already have it, download and install the Samsung USB Drivers. Now, download and unzip the GalaxyNote2Root.zip file. Open the ODIN program by double-clicking the odin3 v1.85.exe application file.] from the website i followed. with this catchy title:
How to Root Your Samsung Galaxy Note 2 Using ODIN for Windows (So Easy Your Grandma Can Do It)
and it rooted with no problem...just that boot loop the next day when updating supersu...and using the google only site is a good idea.
I am having trouble to get the recovery mode on. I can go into download mode easily, but to go into recovery appears to be a trickier issue. I just can't get it. Can you guide me on this....
Simply reflash rom and reroot again.
Flashing stock rom won't erase data. So if after flashing rom device boot up normally, tour data will be there intact, incase it doesn't boot normally after flashing rom then you may need to wipe it.

Just to let you know I have used both sources of available update for super su.
And have never had any problems, I highly doubt your boot loop is anything todo with the su update. The guus on here at xda are superb and will have you back up and running no problem.
GT N7105 with XDA Premium......that is all......

thank you for the positive thinking. but I think I have a serious problem here.
I can not get into recovery, as much as i try.
Before all this happened, i unticked usb debug.
I can however get into download mode.
I really feel that i have critically wounded my phone.

Enter download mode and reflash the recovery using odin. Unticking debug should not put your phone into bootloop neither. . You have to make sure your flashing the correct recovery or rom for your phone model. Depending if you have n7100 or n7105..

OK, let me make sure I understand correctly..I can put some of my fears/worries to rest.
Let me restate
My situation is a bootloop.
My usb debugging is off. (the day after the rooting, I didn't think I needed it on anymore, as I completed the root)
Later that day, just moment before the loop happened, I was updating SuperSu. (something the phone didn't like)
I found: I can go into download mode. I can not go into recovery mode.
(a phone with a bootloop, usb debugging is off, and download mode is accessible)
So:
(When rooting, I opened Odin, I selected the PDA option, choose the proper file, and pressed start. Yellow changed to Green and we were done)
So Now, I open Odin, select the PDA option, choose the correct file for my phone (GT N7100) from likely the samsung website, I see the Yellow, hit start, yellow turns to green, and we're ok?
That simple thing I said 24 hr ago, still you are here.
It has nothing to do with usb debugging.
If you keep it enable /disable, it won't make any difference in flashing.

I want to say thank you to everyone. I flashed recovery and it told of bad install. I rebooted and everything is FINE!
Thank you so much!
Hey guys, I hope y'all can help out.
Back in December I bought a Note 3 on craigslist and all was well with it until today when I received a message from rentacenter saying they have locked the device.
Can anyone please suggest how I can make this phone functional again? I read in another forum that someone with an S5 was able to flash CM12 on his phone and that got rid of lock message.
Go 4 It! Get a new sim also.
You can probably root and flash any custom rom.
I used the following method posted by ttn1185 here on XDA.
PLEASE READ ALL THE STEPS FIRST and ASK QUESTIONS IF YOU ARE NOT CLEAR.
Download Odin3_v3.09
Download TWRP or any other custom recovery of your choice.
Download Cyanogenmod 12 for G900T : https://download.cyanogenmod.org/?device=klte -> Put this on your external microSD card. You can use internal storage as well.
Download GApps for Cyanogenmod 12 http://wiki.cyanogenmod.org/w/Google_Apps#Downloads -> Put this on your external microSD card. You can use internal storage as well.
Run Odin and flash TWRP or any other custom recovery of your choice to your phone. This will set KNOX security flag to 1, meaning no more warranty for the phone if you send it to Samsung to repair something else.
Boot into custom recovery ( with phone off, press and hold Volume Up and Home keys while turning on the phone ) and Wipe System, Dalvik, Cache and Data. This will erase everything on the phone. No need to do ROM back up as we have Stock ROM available for this model to go back if needed. Your choice.
Flash/Install Cyanogenmod 12 zip file and then GApps zip file
Reboot
Let your phone sit for 10 minutes.
To the ultra novice people. I'll add a few extra details.
Download the Odin app and install it on your computer.
Flash the latest version of TWRP using odin and download the .tar version. Also, when you're flashing twrp w/ odin, check the second box that says "AP" and select twrp file.
On TWRP, before installing CM, go to the wipe option on twrp and select advanced wipe. After that, check the following boxes and slide to wipe : cache, data, system, & dav cache.

I don't know how to root but I was able to follow another threads instructions and get my phone running on CM12. I noticed that my s-pen doesn't work using this so I tried to use another custom rom that utilitzes TW but the RAC lock came back. Looks like the only thing you can use is CM for a device after RAC locks it. If anyone has any other suggestions, please let me know.
If you look in the general section there is a post to get your pen working on AOSP roms
in twrp or cwm do a full back up efs everything boot ect
save that folder with all those saved things to your desktop just in case backup your entire rom stock rac crappe done just in case
now i would full erase rom clear internal data where twrp says ar eyou sur eyou want to reboot there is no os !!
then flash another rom or debloated oem ver see what happens
how rac does this idk
you could also see what happens when booting in safe mode ? if rac locks come back or if you can use titaniumbackup pro to freeze rac app while rooted and or keep off wifi is somehow detecting somthing right idk
figured id toss a few pennys out there if all else fail reload from backups
ive only seen a red rac screen on a laptop before it was pretty cool actully and it was @ pwn shop so it was funny to me

i don't see an rac apk, so i don't know how they're doing it.
Does anyone know how to :
a: stop auto play when connecting to the bluetooth car stereo? Kind of goofy having the Samsung song kick on every time I crank the truck and connect the phone.
b: Have info showing when using pandora? When I was on TW, all the info including artist , song, album would populate on my display but w/ CM12, I don't get that info on my screen anymore.
Thanks again to the guys posting in this thread. I'm pretty new to CM and it's been really helpful getting tips from you guys.
Hi folks,
I'm after some information. My Nexus 4 is about kaput now with the battery lasting about 4 hours or so with a full charge so I am looking to move over to my S4 mini for a while before buying an upgrade.
However i don't fancy rolling back to 4.4.2 from 5.1.1 as have got accustomed to it now. so there for I am looking to upgrade/flash it or whatever.
I am quite the novice and have not done this on any phone before so I am looking for a bit of help,
I have looked over xda and read some bits but think someone just telling me would be better, i'm not a tech dunce but I am not 100% confident in this at the moment as there seems to be more than one way of doing this.
What do i need to do first and foremost to make the process go as planned?
I take it I need to "root" the phone first (what does this do ? give me access to the firmware level? is that it?) using a "recovery tool" as they are called (is that right?)
Then after I have done that I can install a fresh ROM onto the phone and basic app's etc.
I have seen these guides:
http://forum.xda-developers.com/showthread.php?t=2364980
and
http://forum.xda-developers.com/gal...i9190-i9195-cyanogenmod-13-0-s4-mini-t3276141
Is it just a matter of following them or are there other things I need to do first, in between or after?
I am not bothered about anything being saved on the s4 mini it can be wiped clean and start a fresh, I don't need any of my data on it backed up
A quick bullet guide or acknowledgement of the two threads above or pointing me towards some better ones would be great and any pointers or descriptions of the acronyms or places in menu's which may have had their names changed or have been moved.
Many thanks Everyone,
Dahools
Hi!, you dont need to worry about anything, the only thing that you need is follow these guides, but make sure if you have the correct variant.
First Install Kies and connect your phone to it( For correct phone drivers). And after phone connect wells, Close kies from task manager.
You Need Odin to install a recovery software in your phone(TWRP, Clock Recovery, Philip). I only used twrp now.
Here is link below with instruction. Download recovery for your variant(i9190,i9192 or i9195 base on your model).
http://forum.xda-developers.com/showthread.php?t=2678420
Suppose if you install TWRP. Boot into recovery, And click Wipe, Do a factory reset , Clear Devil cache, Then go back and install your Firmware(cm12.1 or cm13 for your intended model). And flash Gapps as well. Then reboot. And you are done.
I have tried TWRP for both i9190 and i9192 model. and installed custom roms. Work fine.
Good Luck.
thanks fellas
I went for it with the original links and it worked. (eventually) A bit of user error on my part missing recovery mode on reboot first time and thinking it was done when it wasn't. Only putting the first bit in (root kit v2) then not realising how to flash the next parts. A bit of persistence paid off.
I have a I9195 model and rooting with that clockwork worked then loading the CM13 and then the Gapps. All one after the other in one go finally worked for me! so so far so good, just getting used to Android 6 now I think everything is working though, not put my sim in yet. will do that tomorrow.
If anyone was to follow what I did the big tip I would say is copy everything onto the SD card before you start anything, not as I did at first just putting the first bit on then thinking I can copy the next bit on later . . .
Hi, I'm completely inexperienced with rooting phones and upgrading firmware. But I think I've found the experts =)
I've got a Samsung S3 SGH-I747 which is running Android 4.4.2. I use it strictly with wifi and it has a AT&T SIM card that doesn't have a plan.
My goal is to upgrade the OS so that I can use the TD Bank ap. 2-3 months ago they stopped supporting Android 4.x. So I want to upgrade to Android 7 or 8. Which OS would you recommend? How can I do this?
I've got nothing on the device that I care about too much (just a couple aps that I'd need to reinstall). So wiping it would be fine.
I've also got a Windows PC and a SD memory card (from my camera) - which could be used.
Are you in Canada? If you are, isn't your phone an sgh-i747m?

I'm not in Canada. TD Bank is in the US.
Gotcha. TD Bank (Toronto-Dominion) is headquartered in Canada which is why I thought you were in Canada.
Before flashing anything, be aware of the fact that there is always a risk to flashing a phone with the possibility of a hard brick. Be prepared to deal with such a situation.
I have used the following instructions with great success; however, you may not be so lucky. Proceed at your own risk.
In order to run a custom ROM, you need to flash TWRP: https://twrp.me/samsung/samsunggalaxys3att.html. Download the tar version.
I recommend flashing TWRP using Odin 3.07: https://forum.xda-developers.com/attachment.php?attachmentid=1168421
Open Odin, uncheck everything except f reset time, put the phone into download mode, flash TWRP in the PDA box. When you see the word reset in the status window, remove the USB cable from the phone, remove the battery, replace the battery, use the buttons to boot into recovery. Your phone should boot to the TWRP screen. Reboot the phone to ensure that the phone boots to the existing ROM. Reboot the phone and create a backup of the existing ROM and EFS folder to the SD card. Save both in a safe place.
Select the ROM you want to try and the appropriate version of GAPPs. Copy both to the micro SD card and place the card into the phone. Boot into TWRP, wipe data, system, cache, flash ROM, flash GAPPs, reboot.
I guess I'll order a micro SD card. My camera one is bigger.
Should I install Android 8? Can the phone handle it?
Thanks for the advice!

Before flashing anything, be aware of the fact that there is always a risk to flashing a phone with the possibility of a hard brick. Be prepared to deal with such a situation.
I have used the following instructions with great success; however, you may not be so lucky. Proceed at your own risk.
In order to run a custom ROM, you need to flash TWRP: https://twrp.me/samsung/samsunggalaxys3att.html. Download the tar version.
I recommend flashing TWRP using Odin 3.07: https://forum.xda-developers.com/attachment.php?attachmentid=1168421
Open Odin, uncheck everything except f reset time, put the phone into download mode, flash TWRP in the PDA box. When you see the word reset in the status window, remove the USB cable from the phone, remove the battery, replace the battery, use the buttons to boot into recovery. Your phone should boot to the TWRP screen. Reboot the phone to ensure that the phone boots to the existing ROM. Reboot the phone and create a backup of the existing ROM and EFS folder to the SD card. Save both in a safe place.
Select the ROM you want to try and the appropriate version of GAPPs. Copy both to the micro SD card and place the card into the phone. Boot into TWRP, wipe data, system, cache, flash ROM, flash GAPPs, reboot.

You can try different ROMs until you find one that suits your needs.
Android 8 may not work that well on your phone without bugs as 8.0 is quite new in comparison to the s3.
You can still flash a custom ROM without an SD card if you have TWRP installed. You can boot into TWRP, wipe cache, data, system, connect the phone to a computer, copy over the ROM and Gapps, and flash.
Only flash a custom recovery if you don't care about the Knox counter that voids the warranty. If you like touchwiz, you're out of luck because there are no Android 7 or 8 touchwiz ROMs, only AOSP/CM based ROMs for the S3.
Thanks for the advice! I've made it all the way to installing a ROM. What ROM should I install? I tried installing a Lineage OS one (https://forum.xda-developers.com/android/development/rom-lineageos-14-1-t3680656) but got an error saying it was for the wrong device. My device is a d2att.
Do I need something like this?
https://forum.xda-developers.com/galaxy-s3-att/development/lineage-14-1-d2att-rom-t3774764
So next I tried installing: OCT-N-WEEKLY-20170811-1820-d2att.zip which gave me an error because another package was already partially installed. I used the "wipe the cache" option. It prompted me to install root (second time). It rebooted and had a message about updating approximately 100 aps. Ask for wifi. Said "Just a Sec". Failed to find software on my PC to sync (good - as I don't want it to sync). Booted back into reset mode. Wiped it. Tried installing OCT-N d2att for a second time. And it finally worked!
Then I had to go back to reset mode to install Google Apps.
All in all this took about 3 hours of work and research.
Sidenote: For reset mode it was necessary to remove the battery for 30 seconds to get into reset mode (and then hold the volume up, middle key and power button until the second Samsung screen appears - I found instructions that said wait for the Samsung screen - but there are three Samsung screens!). I was unable to get into reset mode when I didn't remove the battery.

You can install any ROM you want that's compatible with your phone on the NE4/NJ1/NJ2 bootloader. You just have to find one you like the best.

That ROM you installed, OCT-N-WEEKLY-20170811-1820-d2att.zip is a weekly. Meaning it's probably not suitable for daily use and may have non working functions and bugs. Good that you got custom ROMs booting though.

Hi, I'm completely inexperienced with rooting phones and upgrading firmware. But I think I've found the experts =)
I've got a Samsung S3 SGH-I747 which is running Android 4.4.2. I use it strictly with wifi and it has a AT&T SIM card that doesn't have a plan.
My goal is to upgrade the OS so that I can use the TD Bank ap. 2-3 months ago they stopped supporting Android 4.x. So I want to upgrade to Android 7 or 8. Which OS would you recommend? How can I do this?
I've got nothing on the device that I care about too much (just a couple aps that I'd need to reinstall). So wiping it would be fine.
I've also got a Windows PC and a SD memory card (from my camera) - which could be used.

I'm not sure how many of us are out there, tinkering around with the 8+ year old Samsung Galaxy S3 i747 . While I am a newbie, I have enjoyed flashing Custom ROM's , from CyanogenMod, thru various versions of Lineage, and now CrDroid. The newest O/S that I flashed is CrDroid ( based on Android 8 ). Runs great. Stable. Long battery life.
I have always used ODIN to INSTALL a 'recovery' system such as TWRP ( which is a .Tar file )
After TWRP is installed ( using ODIN ) I unplug phone from my computer. Then boot into TWRP recovery ( holding down the three buttons ). I do a clean install (flash) of the newest O/S that I can find ( Android 4.4.2 is really old ). It is that .Zip file that I flash, then reboot the phone. Always works for me. Eventually I learned how to back up all my contacts, SMS, logs, photos, etc.
My banking app works just fine.
BTW I am totally free of Google; no Google Play Store, no Google Pay, no Google Framework, no Gapps, no Google spyware, no Google bloatware, no Google tracking etc. I download all my apps as APK's which are readily available on the Net ( Google them . . . just kidding! ).
My older Samsung S3 i747 was a 'd2att' originally locked to Rogers, in Ottawa, Ontario, Canada. Then switched over to MTS (Manitoba Telephone System). Now running on Bell Canada. My replacement is also a Samsung S3 i747, originally running T-Mobile in Arizona, now running on Bell Canada.
These are damn fine phones.
