Hi all, every time I want to either install a custom rom or flash back a stock firmware it is an impossible task. Nothing works from the instructions to the firmware's themselves.
I've had a few custom firmware's on my tab s T705 tablet all of which are garbish and reboot themselves even when doing something simple like watching a video!
So wanted to flash back to stock firmware. However no matter what "stock" firmware you download for your model tablet even from reputable websites either the Samsung logo hangs at the start after a flash or twrp fails to flash a firmware.
Why is is so difficult to
a. Get hold of a stock rom
b. actually flash it and get it install!!!
Ive tried all sorts, wiped the entire tablet in twrp, used odin, used so called "stock" firmware, used and paid for skipsoft toolkit which I highly regret no as its utter usless doesn't do anything it states it does and their help section might as well not exist.
So I have a tab s with nothing on it and nothing that wants to install onto it.
What do I do? as so far its doing really nicely as a f**king paperweight.
That's really strange. I never had problem flashing the stock ROM from Odin on SM-T800.

Seriously mate, don't know what to do, nothing seems to work. No firmware seems genuine. How can I obtain an original firmware without signing up to sites or pay for a premium server to get the file?
Thanks
Currently I wiped the entire system via TWRP except the micro sd that has the firmware zip file on.
This is a recent log from twrp when trying to install a "stock" firmware. Hopefully someone can figure out what's going wrong
Problem fixed. Just kept trying different firmware roms online and found an original 4.4.2 that worked. just updating to 6.0.1 through Samsung updates now. And keeping the downloaded file safe and going to do a android backup dump from twrp once its done.
Thanks
how to mark this thread as resolved?
New issue. All I want to do now is just root the stock firmware to allow me to use certain apps. However every time I try a root either auto cf root, supersu, kingroot. All that happens after flashing the root is the Samsung logo boot loops saying recovery cant enforce in red and blue text.
Is knox preventing it because yet again my tablet does the opposite of what the instructions say.

Try reinstalling the stock firmware, and then install TWRP and get the zip package for SuperSU and install the zip package thru TWRP.

I have T-Mobile SM-N900T with N900TUVUCNB4 Latest firmware 4.4.2 it came with the phone.
I have tried to install and root this phone many times. And every time it goes into recovery it boot loops. No matter what I have tried. I have tried CF-Root for the Kitkat, I have installed Recovery from TWRP 2.7, via Odin. Every time I says it updates but just goes to recovery and loops. I know that it has already tripped the Knox Warranty it now says 0x1.
Maybe if there is a Rooted 4.4.2 rom that can be put on via odin that might work. I have not found one. Or if anyone can give me directions on how to install any of the roms for this phone via odin it would be helpful as well.
I would like to root due to I need to remove allot of the bloatware on the phone its really full of apps that I will never use.

I am for sure that you did not use cf autoroot for the euro phone. I am willing to bet that you might also be trying the wrong recovery. Only 2 exist for the 4.4.2 boot loader.

I was having the exact same problem you are having right now, and BACARDICIMON helped me out of it. I downloaded the original 4.2.2 firmware from sammobile.com and then used odin 3.9 and flashed that. It started working perfectly afterwards.
Rooted/Flashed my phone a long time. Constant bugs and errors. I really don't remember what all I did but I think I almost have it completely unrooted and back to stock. However, I can't update OTA. I've reflashed using this file, http://forum.xda-developers.com/showthread.php?t=2658486. Fixed just about all my issues and I actually have a lot of space on my phone. When I try to do the OTA Update, it doesn't install the update. Once it boots into recovery mode to install the update it gives an error. Can someone help my to 100% fully get my phone back to stock and be able to install OTA updates? I'm clueless.
First, did the 4.4.2 ota fail after a certain percentage? If so you may actually be partially updated already. If so, flashing MJB firmware/bootloader will hard brick.
Install and open Terminal Emulator and enter this:
getprop ro.bootloader
If it says MJB, you are still on 4.3 and can refresh that. If it says NE4, do not flash MJB!
If you can still flash MJB, there is a thread in General (I think that's where) that has the Odin flashable firmware package. Flash that with Odin and factory reset. Then try the OTA.
Factory resetting with stock recovery installed will wipe internal sd card, so back up first!
There are also a few threads in General that can help you update if the OTA continues to fail.
I'm unrooted. At least im pretty sure of that. I cant run superu anumore and root checker says im not rooted. Can I still access the terminal without being rooted. I know I had clockeork mod recovery. I also had used cyanogen mod at one point. Now I have the stock recovery but when I boot into recovery I get an error. I will post the error and install percentage as soon as the ota update downloads.
Yes, you can still run getprop w/o root. Just install terminal emulator by jackpal from the play store.
Yeah it said I747UCUEMJB. Like I said my recovery gives me an error. When I try flashing at all with odin it fails. Trying to install the ota update now. After it fails ill give the error recovery gives me. OTA update fails at 24%
Ok, booting into Android system recovery gives me a no command error than it shows the list of options. When I go to reboot system now, it gives me a no command error as well. Download mode used to give me an error, might only show up when attempting to flash something. However, these are the details of my ODIN Mode right now.
Product Name: SGH-I747
Custom Binary Download: Yes (1 Counts)
Current Binary Custom
System Status: Custom
QUALCOMM SECUREBOOT: ENABLE
Warranty Bit: 1
BOOTLOADER RP SWREV: 2
When you try to flash the firmware with Odin, what does it say in the message box?
Have you tried flashing TWRP via Odin?
A lot of people seem to be having issues with the OTA failing at 20-something percent. No idea why though. I know some found that their firmware was partially updated afterwards though, which is why they couldn't flash with Odin. Need to know what odin says about the failure to know for sure though.
You might need to factory reset btw.
I've already did a factory reset when I flashed this latest rom from that thread I posted.
Point me in the right direction of the firmware I need. I've got AT&T btw.
Try MJB firmware again. Im assuming that's what you tried to flash with odin earlier right? When/if it fails again, copy the text from the message box and paste it here.
So you want me to try flashing using Odin with that firmware I provided in that link? Like I said, ODIN on the pc gives me an error. I'll provide the error later when I get off work. Before I just put the firmware on my sd card, went into refovery mode and installed it from there.
From what I can see that is for flashing in recovery only. Of in only flashes .tar and .tar.md5 files.
This is the stock MJB firmware you can use in Odin:

Its from enewman17 in his how to update thread here (step 4):
http://forum.xda-developers.com/showthread.php?p=53563776
If you still want to update to 4.4.2, that thread has had a pretty good success rate from what I've seen.
Let me know if you have any ither questions about this.
I'll try ut as soon as I get home from work and posy my results. Thanks for the help so far!
Wow I think one of the reasons I couldn't use ODIN after trying to unroot, is because I never had turned on USB Debugging mode. You wanted me to just go through Step 4 for right now right? Just to get back to stock 4.3 AT&T S3 like right out the box?
Thanks so much Doc. After following step 4 on that thread I was able to Ota update!

Been using my newly updated S3 and now the Touchwiz Home stops on startup and resets my default app settings repeatedly. Not sure what's the deal, tried suggestions on diff sites and am trying a factory restore, wipe date, and wipe cache partition. Any clue how to fix this?
PS: Seen in Android System Recovery it says KOT49H.I747UFNE4. Should that be I747UCEMJB since that's what mine is and recovery still gives me no command when I start it up?
You said you had updated with the OTA so NE4 would be correct.
As for recovery, if you want to keep stock recovery, enewman17 has it available in one of his threads (in development section I think). Redland that by itself and it ought to be good to go.
Otherwise, use Odin to flash TWRP recovery.
Factory reset should take care of the launcher/home issue you mentioned. You may not be able to though since it sounds like recovery is corrupted. Fix recovery as I said above and then try the reset.
If you factory reset with stock recovery installed, it will wipe your internal sd card. With custom recovery it will not.
You could also try clearing data for Touchwiz Home in application management.
I am having issues updating OTA too. It gets to 100% and then says my phone will reboot in 5 seconds, then it reboots and some at&t logo with a % counter comes up, that gets to 100% then it reboots into Android and it still says 4.3...what am I doing wrong? Anyone have any advice? Many thanks if so.
Thats a new one for me...how exactly are you going about updating? Are you using one of the threads here? Have you recently modified anything?

I am trying to update by going to settings --> more --> about device --> software update. Not using a thread, no. I was rooted and uninstalled google books and newsstand then unrooted and did a factory reset in stock recovery because I found out that if you are rooted the OTA update won't take. I am 100% bone stock now except for the 2 bloatware apps I uninstalled. I have since reinstalled them via the play store , but I hear they need to be system apps?
They do, but they also need to be the same versions that were originally included. If you get them from the store they'll be updated and will cause the ota to fail.
The development for the AT&T I747 has been discontinued by the developer. Thank you for your support.
WARNING: YOU COULD BRICK YOUR PHONE
UCUFNJ1 4.4.2 incremental update contains firmware.... bootloaders and modem baseband.
MUST BE ON UCUFNE4 FIRMWARE TO CONTINUE!!! Guide can be found here. http://forum.xda-developers.com/gal...are-update-t2808654/post53984772#post53984772
This is the perfect time to use this update to return your S3 to stock for resale or whatever. Download and save these files for when you are ready to return your phone to stock.
*This is a rooted NE4 system.img, stock recovery.img and boot.img. The install script will format system and factory data reset. /media is safe.*
1. Flash restore zip in a custom recovery. CWM, TWRP, Philz. https://www.androidfilehost.com/?fid=95784891001611561
2. Boot your phone and go through setup.
3. Use triangle away and clear your counter. http://forum.xda-developers.com/galaxy-s2/orig-development/2014-01-15-triangleaway-v3-26-t1494114
4. *Optional* If you want a clean un-rooted phone for the update do this now! , Go into SuperSu >settings>full unroot.
5. Reboot your phone.
6. Search for the OTA in the about settings, download and let the phone update.
Or download this and place in the root of your phones internal storage. Reboot into recovery and select the update from update.zip https://www.androidfilehost.com/?fid=95784891001611091
Advanced users.
The original OTA cfg file. https://www.androidfilehost.com/?fid=95784891001611092
.cfg file goes in root/cache/fota
Rename the .cfg extension to .zip and you can rename it update.zip yourself or you can actually flash it in a custom recovery once renamed. if you choose not to use the stock recovery to update.
*You will loose root during the update* But the bootloader is not locked so you can still Odin your favorite recovery and flash SuperSU.
TWRP 2.8.1.0 Odin tar. http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.8.1.0-d2att.tar
SuperSU http://download.chainfire.eu/589/SuperSU/UPDATE-SuperSU-v2.16.zip?retrieve_file=1
Once you flash your favorite recovery via Odin, you need to be ready to hold the Volume Up, Power and Home button combo when Odin reboots your phone. If you don't catch it, once the OS boots it will replace recovery with the stock version. Once SuperSU is installed your recovery will stick.

For the advanced users, should we be able to install the update without any issues? I saw in another thread that someone had installed but now their phone will not boot past the Samsung logo to anything other than a black screen.
Also, do we know what this update contains yet? Other than new bootloaders, removal of root, etc.

You know if your not wanting to return your phone to stock I really wouldn't mess with this update. Far as the user who couldn't boot... Idk I wasn't there to watch them update. This whole mess with the S3 is exhausting. We haven't got a real Odin release so I'm woking with what I can extract from my phone after updating. The system.img in ne4 zip is 100% stock except for root. So I know the update worked because I did it. Also not sure what was updated either... The kernel yes... Firmware yes, all the system apps get patched so without decompiling ne4 and nj1 apps and comparing them afraid I have no idea what the update fixes or improves.
Thanks for all you do for us S3 owners, enewman17.
If we upgrade to the new NJ1 firmware, and then flash your latest SRX Rom, I assume we cannot then use your "restore.zip" to once again go back to NE4 stock since we would be on NJ1 bootloader? If so, is there a way to go back to NJ1 stock if we later want to sell our phone?

Towelroot no longer works after the NJ1 update. Can the CF-AutoRoot still be used? The only version at http://autoroot.chainfire.eu/ says it's for 4.0.4.

Yeah, I saw that, but I never had a custom recovery before, that I know of at least, and I suspect a lot of other people finding this thread in the coming days are going to be in the same boat as me. They just want SuperSU so their favorite 1 or 2 apps that require SU can continue to work.
Has anybody tried CF-AutoRoot yet on the NJ1 4.4.2?

I can confirm this as a root method for NJ1. You were exactly right regarding immediately booting into recovery after installing TWRP thru Odin. The files provided in your links (TWRP 2.8.1.0 Odin tar. http://techerrata.com/file/twrp2/d2a....1.0-d2att.tar and
SuperSU http://download.chainfire.eu/589/Sup...etrieve_file=1)
worked exactly as stated.
A BIG thanks to you. I can't live without AdAway, TiBackup and Xposed anymore! The few days without root left me a little grumpy.
And regarding the NJ1 update as a whole...I THINK the baseband upgrade IS an actual upgrade. Since NE4, I always thought Wifi operated was somewhat choppy/throttled. THIS looks to have been improved back to ICS "standards". Re: voice, I've had a handful of dropped calls, broken up calls, and choppy data in low signal areas over the past few months on with NE4. Initial observations (albeit a tad premature) lead me to believe that this has improved as well based on a weeks worth of data use and a few calls in a "controlled" environment (the area and physical structure of my work office complex is not cellular signal friendly to begin with) I have also noticed that boot-up time has improved a bit as well. Thanks again for your efforts with the ATT GS3!
I flashed CF-Auto ROOT via Odin without success, unable to gain root access. Followed your instructions via TWRP and flashed SuperSu 2.16, my SGS3-i747 is properly rooted and functioning perfectly on UCUFNJ1. As always, thank you very kindly for all your valuable time, effort, hard work and guidance. Be well, sir!

What version of Odin do we need to flash that TWRP, or do you have a link handy?
I've seen quite a lot of different Odins out there and don't want to brick my phone by using the wrong one.
Any pitfalls to watch out for if using TWRP for the first time? I'm sure there is going to be a bunch of people having to do this now that both CF-AutoRoot and TowelRoot doesn't work anymore.
For me, personally, I just use root for AdFree and to edit the font fallback order to properly support Japanese instead of Chinese glyphs on shared Han-unified Unicode codepoints.

Use Odin 3.0.7
Not really any pitfalls to TWRP. It has an easy clean user interface and it works.
Once you have flash Super Su, in my how to ne4 update there is a flashable stock recovery. You just flash it with TWRP and once you reboot, stock recovery will be back on you phone.
Hi enewman17,
Thanks for your posts and work. I'm hoping you can help me get the new NJ1 update installed and rooted.
Here's where I'm at: AT&T SGS3 on rooted stock NE4, installed using your guides from back in June this year.
The OTA NJ1 update downloaded but failed to install (as did the NE4 OTA back then, I assume because I was rooted).
My phone still has the TWRP recovery from the previous update, so I was hoping I could install using the original OTA cfg file download from the "advanced" section in your OP so as to avoid factory reset, etc.
I downloaded the file, renamed to update.zip, and copied to my SD card. However, when I boot into TWRP and try to install it, I get an error after the system check, something like "assert failed ro.secure==1". I guess I'm doing something wrong, maybe I'm mistaken about how the original OTA is supposed to work?
Again, I'm trying to end up with a stock, but rooted, NJ1 firmware but hopefully without having to reset/lose data and settings on the phone. I don't really care right now about resale or making it look like I haven't messed with it.
Thanks for any help you can provide! Let me know if I can provide any additional details.
I am actually looking to do the exact same thing. Currently rooted, with a lot of the AT&T apps frozen via Titanium Backup.
Hope there is some way to accomplish this without returning to stock!
Thanks in advance!

I have been reading through many threads last night and today trying to figure out the best way to get rooted stock back on my AT&T S3 i747. I had hoped to figure it out myself, but have come to the realization that I need a little guidance.
In light of that, I'll try to give concise information. First of all, I am simply looking to end up with stock.
Series of events:
*Have had stock since given this phone in August; it was kept up to date with OTA and it was current (4.4.2) as of yesterday morning when att pushed the newest update to the phone.
*I rooted the phone in September using CF root and Supersu to both root and block Knox and it had been working very well until the attempted update yesterday.
*I no longer have a custom recovery backup
*yesterday my phone went through the update (download and install), but when it rebooted, it only made it through the Samsung splash screen and then went black.
*I am able to boot up both stock recovery and into download mode
*Using the stock recovery to reset the phone has not fixed the problem
Having never used Odin or installed a custom ROM, I am hesitant to flash anything to the phone until I verify that the new bootloader (that is now possibly there due to the OTA update) and anything I try to install won't conflict and make my problem worse.
It seems to me that I should use Odin to load a custom recovery, make a backup, and then flash a ROM. If that is correct, would the recovery ROM found in this thread be the correct one: http://forum.xda-developers.com/galaxy-s3-att/general/ucufne4-to-ucufnj1-update-t2941792
If it is not the correct ROM, what would be the correct one?
Thank you,

For a custom recovery, flash the most recent tar.md5 file from here using Odin: https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
Boot into recovery, create a backup, and flash a custom ROM. I recommend the most recent CM10.2 so you can determine the bootloader currently installed on your phone. Once you determine the bootloader, you can decide how you want to proceed.
Thank you so much for your response.
I did as you suggested and I do indeed have the UCUFNJ1 bootloader. That does help me determine which direction I can take. Although, now having tried out a non-Samsung ROM, I may have changed my mind about keeping stock on the phone. If I decide to go back to stock, I'll just keep my eyes open for a stock ROM that states it requires that bootloader, correct?
Again, thank you so much for your help!
So something I did went wrong and I'm at a lost to what to do. I tried searching google and here but if someone could point me in the right direction, I would be most greatful.
So I install 6.0.1 using smartswitch which went just fine, but I decided to root it using odin and cf-autoroot, but that seemed to fail and I was stuck in download mode. I manage to exit download mode but it just remains stuck on the samsung logo. I am able to boot into twrp recovery (had installed already from 5.01. root) and I did a factory reset but I'm still stuck.
Any ideas? Any hope?
Update: Got it working buy downloading henklbr stock rom located here: http://forum.xda-developers.com/gal...firmware-selection-sm-t700-sm-t2960225/page18 I think I screwed up odin the first time by not having auto-reboot checked. And can I say samsung-updates needs a better download provider, I did not want to wait 8 hours for their download to complete.
If you are reading this because you ran into the same issue, rooting with cf-autoroot still didn't work for me, I ended flashing twrp via odin and and then going into twrp and flashing superuser. Now I have root again.
Just saw you fixed the problem.. may my time wasted rest in peace :angel:
Yeah uh last I and others I know checked cf-autoroot does not work with android 6.0.1
Feel free to try this though:
Okay so here is how you can MAYBE fix your T700.
1. Download a firmware or ROM from here or other source: http://www.sammobile.com/firmwares/database/SM-T700/
2. Download Odin v3.10.6 on your PC.
3. Use Odin to flash the firmware or ROM on your T700. (Don't know how? Try to find a general guide on flashing firmware)
Once you do that feel free to use this root method that works on the T700 running 6.0.1:

yep, just download a TWRP with a TAR extension for ODIN and happy flashing... You can root after installing your Rom. The same can be done if you install the stock ROM before installing TWRP and rooting for debloating.
Thanks anyways ZimriTech, Google lead me to be leave CT auto root would work, lesson learned.
