So This is my first time posting on any forum site for help, and i was refereed to XDA by my roommate. so what happened is a few months ago i asked my roommate to root my galaxy s3 SGH-I747, after he rooted it through odin and all seemed well, BUT we never could get the phone to recognize the root and was still unable to access any root functions. so after a few different attempts we gave up. i assumed that my roommate had removed the root (bad call) but never gave it any thought. a few days ago at&t started bugging me with a software update. i just hit ignore and it would pop up again in a few hours and the icon would never go away. so i gave in and started the update. i didnt pay the phone any attention while it "updated" but later that morning i went to turn it back on and it would get to the Samsung screen then the next screen but after that it goes black and vibrates. i showed it to my roommate and he informed me that it was never restored back to official frimware like i had previously assumed. and that it never should have received the update bc it was still on a custom frimware. we tried flashing the stock frimware back on the phone and every time it would fail the nand write. i believe it was updated to 4.4.2 before i received the update from AT&T and we tried many different ways too restore it i even tried the recovery in Kies 3 but all it says is "connecting" then connection failed. so far nothing has worked. i believe that the update contained android 5.0 and maybe that is the reason none of the other ways we tried worked. i have been researching for hours trying to find a similar case but nothing matches, and i cant find a single working solution that doesn't involve possible making it worse. i can access both the recovery and download modes. please any information or help would be greatly appreciated.
Flash a custom recovery such as Philz Touch via Odin, install cm10.2 via your custom recovery. This should get the phone booted so you can determine the bootloader version on your phone. The NAND error is due to the fact that you are trying to downgrade the bootloader in Odin. Don't flash anything with Odin until you determine the bootloader. Doing so could hard brick your phone.

I am planning on rooting my friend's stock i317 running the MC3 stock firmware. He recently got a carrier replacement i317 due to a hardware issue but I had also previously rooted his other i317 and installed a CM10.2 nightly ROM. Upon using the same method of rooting his first phone on the new one, I ended up soft bricking his second phone. I basically used ODIN to flash a few different recoveries but when I would boot to recovery each time then the Galaxy Note II logo would start flickering for a few seconds and then the screen would go blank. I tried using ODIN to restore to JL2 and upon successfully restoring, I couldn't get past the boot animation. I told my friend to replace the phone again as I couldn't even get the phone to boot up successfully no matter what I tried doing to fix it. Maybe I had to find and ODIN the MC3 firmware to successfully boot the device so please let me know what I did wrong which prevented the device from booting successfully.
I don't know whether there was recently a major AT&T firmware update that changed the security on the device which prevented previous methods of root from working so please update me on any changes. My friend just got a new i317 today and I would like to root it successfully as the AT&T warranty center was nice enough to replace his phone but had to void his warranty due to looking at the flash counter. I just found an app called Framaroot which looks much simpler to use

I have been rooting and flashing ROMs on various Android devices for a long time now so I am up for using any root methods no matter how advanced they may be including using ADB. I did not have enough time to research about the i317 so it was my fault that I could not successfully root his device. Any help would be much appreciated.
Thank you

Add I prefer TWRP recovery over CWM!!
From everything you said you did it sounded right. Cuz you even tried going back too the original firmware that was shipped with the device!! But I didn't seed that after you flash the Rom,, did you try to do a factory data reset. Sometimes that's all it takes to fix that bootloop problem.
One other thing if you can get into download mode then the phone is fixable. Think it was just over your head on the process on how to get it back to fully functioning... lol
We've all been there. Think it's because we panic when something isn't working the way we want it TO..

So I have an Att Note 2, which is bricked or soft bricked. I am a very rookie Android guy when it comes to modifying or hacking. I did root my Note 2 with Cyanogenmod. However, I missed S Note and the use of my S Pen so I researched a bit to get back to stock with the use of Odin and stock roms found on the net. I was successful, and actually amazed it worked. Long story short, a few days after that, an OTA update hit my phone, didn't even think about it and began the download. The phone downloaded the update, and rebooted to complete the install. The problem is, during reboot, the phone got stuck on the "Samsung Galaxy Note II" screen. I researched a bit online, and everyone said get to recovery mode and do a few things. Problem is, I can't get into recovery mode, I can only get the screen described above, and the download screen, THAT IS ALL. Looked a bit more online and attempted to flash various stock roms with Odin. Some were successful, Odin passed, and the phone would get stuck on the Note II screen again, and would not boot into recovery mode, same issue with only being able to access download mode. The unsuccessful flash attempts got me to screen informing me that Kies needs to be used to update my firmware. Kies showed a recovery code, which was downloaded, but unsuccessful. It would download all the way, but at the end of install, it would fail. Funny thing is it would work enough to get me back to the ability to get into download mode. I just want my Note 2 working again. Is there any way to wipe my phone completely clean, and start over? Or is there any way to even re-root it, or flash any sort of rom on there, just so I can use the damn thing? I need some help by you pros out there ! Please!

Try flashing a recovery for ur device with Odin, not a ROM, just flash twrp recovery with Odin, after u flash the recovery u will be able to access recovery and flash a stock ROM through twrp. I think what happened to u is when u flashed the update it tried to right over the unlocked bootloader which caused the soft brick, try flashing the recovery for ur device and if that doesn't work try the above posters way...

Hi all, hope somebody can rescue me!
I have an N7100. It's been running stock ROM 4.1.2 for ages (rooted). I've rooted and loaded ROMs on a fair few devices over the years, but typically by following step-by-step guides - I'm a noob to all intents and purposes.
Last night I decided to upgrade to 4.4.2.
I did it without performing a wipe first.
Backed up apps and settings using Titanium Backup Pro
Downloaded N7100XXUFNE1 from Sammobile (sammobile.com/firmwares/3/?download=32635)
Loaded it via Odin 3.9
It worked, in a fashion, maintaining most of my data and apps etc, but I couldn't get wifi to turn on and I kept getting error messages saying '[App X] could not be loaded'
I decided to bite the bullet and do a factory reset (by booting into recovery).
I still couldn't get wifi to work, but my bootloader had stayed at ME3, so I decided to apply the latest bootloader (ND3) as I read somewhere that this could be the issue (I wasn't overly concerned about Knox as the phone is almost 2 years old now anyway).
I applied it via ODIN again, except loading the file into the 'BL' section rather than the 'AP'.
Since doing that, it's stuck at the boot screen 'Samsung Galaxy Note II GT-N7100' and the only way to get out of it is to pull the battery.
I can got into 'Download Mode' but not into 'Recovery Mode'.
I have tried applying MJ5 bootloader.
I have tried reinstalling the whole stock again ROM again
I have tried applying Philz_Touch_6.07.9-n7100 recovery
All show as having completed successfully in Odin, but none of them changed anything - I'm still stuck at the boot screen
Does anybody have any ideas of what else I might try?
Thanks

Have you tried flashing TWRP instead? This happened to me and got stuck on recovery boot, CWM and Philz Touch wonb't load. Flashed TWRP and worked like a charm.
I am having similar problem.
Tried to flash the TWRP Recovery from THIS via Odin.
Still phone isn't going past the Galaxy Note II logo.

It processes OK and Odin says 'Pass!', but then it automatically restarts and gets stuck at the boot screen again. Still can't boot into recovery mode.

Thanks for the suggestion. Just tried that, but unfortunately it just does the same thing ....
Man do this.....
Get older odin (personally my preferance nothing else)
Flash the latest stock rom that u have
It will say pass and the device will go into bootloop
Now remove battery any stick it in (just to stop bootloops)
Enter recovery (that shld be stock now)
And do a factory reset
If no recovery......get a custom one and do it
Then let the phone do its thing:good::good:

Thanks for the suggestion. I've tried doing just that (although not on an older version of Odin) and it hasn't helped, I can't get into recovery.
I will give flashing the Bootloader a go via the AP rather than BL when I get back from work tonight though. Cheers.

Hi, I do appreciate you're only trying to help but, as explained numerous times in the thread, that's my whole problem.
In summary:
The phone gets stuck on the boot screen
I can't boot into recovery
I can only get into the odin download screen
Flashing a full stock rom doesn't change anything
Flashing Philz, TWRP or CW Recovery doesn't change anything
Reflashing the bootloader doesn't change anything

Just to close this thread off, I've now paid to get the phone sorted at a local shop. Took them a while (think their first level support just tried all the things I'd already done), but their occasional staff member and all round guru managed to get it sorted. I don't know what he did as I didn't get the chance to speak to him. Cost me £30.
Hi everyone
Long time xda follower, newly registered, since I needed to ask a Q.
I rooted and switched to Lollipop on my ATT S3 (i747) a few months ago, Lately, I've started noticing battery issues as well as network issues with this ROM. I figure it is time for me to go back to stock.
However, if I remember correctly, when I tried previously the phone refused to downgrade back to stock. Kies was helpless because the trip counter had been reset (or something similar).
Please, is there a good how-to on downgrading this phone from Lollipop back to stock? If yes, would someone please point me to it?
Much thanks in advance.

Nope! No go!!
Triangle away reset the counter.
The stock recovery works well. I was able to boot to recovery and wipe the data and all that.
Odin says "SW Revcheck Fail" when trying to download the stock rom.
I rebooted into Lollipop, downloaded Triangle away again and reset the counter. Still Odin fails with the same message.
I tried flashing ROM first then the recovery as it was suggested in that link. Nope. Again "SW Revcheck fail". For the record, my SWREV appears to be 3. It is supposed to be 0. Triangle Away does NOT reset this. It did reset another counter (as reported by Triangle away itself - was 5, got reset to 0).
I remember *this* was the problem previously as well, hence the original Q:
How *do* you get back to stock from Lollipop on the Galaxy S3/ATT?
Meanwhile, although Keis failed to recognize the device, I tried to run a firmware recovery manually. It took a long time and in the end failed. It also messed up the recovery, so I had to flash CW again to make it bootable. I'm still back up with Lollipop at this point, but I don't want Lollipop.
Anyone anything else I can do? Any other guide out there to downgrade?
Thanks again

The thread you linked is for the international version of the s3.
Before flashing anything else, you need to confirm the bootloader on your phone to ensure that you don't flash anything that attempts to change the bootloader if your bootloader is mjb or newer.

Right. I finally figured it out.
First the 4.1.1 FWs weren't flashing (in other words SW REV CHK FAIL) was basically indicating that my Bootloader was far ahead of the 4.1.1. I dropped 4.1 after I figured that part out.
Next, I tried to flash a 4.4 (UCUFNE-rooted-odex is available as a zip-flash) through CWR, which didn't work (no boot, stuck at splash).
Next I got hold of a 4.3 (UCUEMJB-2024954-REV04-user-low-ship), which successfully flashed through Odin (repartition checked), but there was no sound, IMEI indicated null. Service Mode yielded a blank screen.
I flashed TWRP through Odin (was working on CWR since the beginning) and then flashed the UCUFNE-rooted-odex above on top of 4.3 through TWRP, which was successful, still no sound/IMEI/service mode.
Finally I got hold of the UCUFNE-Modembaseband zip (a small one - 20MB) and flashed that through TWRP. Both sound and IMEI came back.
I'm at 4.4.2 now, but an OTA update from ATT failed (probably because it went through TWRP)
Now I'm back to stock, albeit rooted ROM (because of the Rooted-Odex 4.4 flash), but I am a happy camper.
Thanks to XDA for various bits of info here and there. But essentially *this* is how you go back to stock from Lollipop.

So my issue is pretty similar, see what you guys think. i been trying everything i can think of.
i updated from xtrestolite 2.1 to 2.2 with out wiping. everything worked fine except when i would make calls, the other people could not hear me. so i updated the bootloader and modem again (i had done it before) and the problem persisted. i flashed back to stock and was getting stuck at the s6 edge screen. the only way to get around this was and get my phone to boot was to flash aou kernel. i was still having a similar issue with calling so I download a modem from a diffrent server and all of a sudden, it was working again on stock firmware... AWESOME!
now that i had all that done and my phone working as it should, i reset my phone for the first time and i got the FRP lock, wont boot phone because custom kernel. GREAT
I then flashed stock of6 again, the tar ball, and the 4 piece version. no dice
i then found of8, tried to flash that still no dice.
id love to flash twrp and load a rom on, but FRP is a alsjdflajs.
the phone will flash successfully, but upon reboot, it will go into recovery, run its course, reboot, and get stuck that the galaxy s6 edge screen.
i use the vol and power click during recovery to see what its doing and everything seems to go fine. it will then say failed to mount /data. im hoping flashing this with the pit file will work, but i cannot download the pit file from my work computer (hahah its blocks on 4shard and mega).
anyone have any other advice? i will update if i figure it out.
Regards team,
-Mad
p.s. none of this is xtrestolite's fault, that rom has been nothing but good to me.. my phone has been picky though. after 5.1.1 i had to flash a custom kernel in order for the digitizer to function properly.... any help is appriciated guys.
SO UPDATE!
nothing good, i tried the pit with of6 and of8, no dice. still stuck.
anyone got a s6 edge w a broken screen? you can claim it lost for all i care.
no one?
i guess if anything past flash stock firmware people dont know? was hoping for alittle more insight.
im sure if i could flash a kernel i could get it to turn on, but FRP has be at bay...
no help for you bro...Samsung just needs to release there software fixing for this comunity...I'm looking a for a dev to answer my question in this section about just flashing zip files in twrp instead of using odin or whatever other methods that can avoid all these problems that are all similar...hopefully in next few months it will be addressed

I initially used odin to flash OI1 update, after a rom I was using caused problems and I got bootloop. It changed bootloader value to b:3 and I'm unable to downgrade now so I used smart switch which didn't recognize device so used emergency recovery and still bootloop. I have factory reset and wipe cache multiple times along with adb side load and individual flashes of bootloader, modem, kernel, flashed custom kernel and twrp to access fix permissions and to mount partitions with advanced wipe etc and still wont boot past logo. Also during one fix attempt phone said can't mount system.. Idk I'm not understanding where the problem is .everything says successful but I'm still in bootloop. Please help. I've spent hours everyday for the past week searching & trying different things that seem might help so open to any suggestions.
