downgrading to 4.1 - AT&T Samsung Galaxy Note II

Hi guys.
I'm trying to down grade my SGH-I317 rom from 4.3 to 4.1 in order to unlock it. I've done the system wipe and cleared cache ,but when I attempt to flash the 4.1 rom in recovery it gives the error message "e signature verification failed".
Does this indicate that I need to flash a different rom like Cynogen or Clockwork BEFORE trying to flash 4.1? Or is there something else I've skipped over that could cause the failure? Or is it the file itself that's not compatible?
4.3 rom is stock JB
I'm accessing everything from external SD card not via USB.

Which guide are you following? Typically the revert to 4,1.x is done with an Odin flash rather than recovery.
If you are on the 4.3 bootloader or higher you use UCALJ2. Otherwise you can use UCAMA4 or UCALJ2.
See the guides in general by @perez6991 and in q&a by @dicksteele for additional information beyond that offered in the back to stock LJ2 guide stickied in general.

Okay, I'm heading over to those sections to research. I've read several guides on the forum but kept getting a little confused on which flash method to use so I don't end up bricking my device. Thank you for your reply.
One more question , if I'm simply flashing Odin I wouldn't boot in recovery to do so? I think I've confused myself.

The device has (2)....3 button combinations that are used to access either the recovery....or download mode...
Recovery is used for flashing the most common .zip format...like a CM rom...
Download mode..(Odin mode)...is used to push a complete package to the device...that generally includes a radio image, recovery, and in some cases the bootloader...and these files are generally a .tar or .img. designated file...
Using volume up, power, and home buttons at the same time will boot you into recovery...
Using volume down, power, and home buttons at the same time will put the device into download mode...
The difference between the two modes is very important when flashing files...so read carefully before selecting modes or files to flash...g

I'm a little aggravated I've been trying to flash the 4.1.1 rom but mobile Odin is not recognizing the file as a zip file. I'm not sure what the problem actually is ???

Try the Windows (PC) version of Odin. Also make sure you have unzipped and are working with the ---.tar.md5 file, not the zip file.

Follow this. http://forum.xda-developers.com/show....php?t=2618447 .
I followed sections all sections 1 threw 3. At section 2 the link for the I317UCUBMK6-TZ-PARAM.zip did not work. I used this link instead.
http://www56.zippyshare.com/v/16559598/file.html
At section 3 don't be alarmed when it says it's downloading the update but it doesn't show percentages. It is downloading. In fact for me it automatically downloaded the 4.4.2 update instead of 4.3. It skipped it and went straight to kitkat. It took some time but I have Official KItkat 4.4.2.
Hit Thanks

You only need to flash the J2 modem from version 4.1 to unlock the phone.

[Q] Unable to flash Stock ROM

I bought a T-Mobile Galaxy S 3 LTE with model number SGH-T999L. I used Odin V3 1.85 to flash TWRP recovery and CyanogenMod 10.0.0.
Everything went well but my camera doesn't work. On launching the camera, I get a "Can't connect to camera" error and it quits. The same behavior is observed when using other camera apps. I tried the instructions in this thread(http://forum.xda-developers.com/showthread.php?t=2239414) but it did not fix my problem. I now want to go back to my stock ROM. I successfully downloaded and flashed stock recovery using Odin. However, Odin fails when I try to flash the stock ROM obtained from the samsung website. It gives me a "write failed" error and stops. Any tips or suggestions to help me out would be appreciated. Thanks
Is it supposed to use T999 firmware?
Only odin flash T999L firmware. I dont see it released yet at samsing-updates.com though.
Maybe samfirmware.com? I can look later.

Why not reflash the stock ODIN flash rom and make sure it all works ok for you, that will tell you exactly what the problem is.
If the stock rom is working properly, then there is only one thing left which is the culprit and that is the CM10/AOKP/AOSP
or PORTED roms which many people seem to like flashing.
The CM10/AOKP/AOSP and ported roms are excellent if you are a developer or if you like to do a lot of experimentation with your phone.
So the thing to do now is reboot your phone to recovery mode, do a "Factory Reset", "Wipe Cache", "Wipe System" and "Wipe Dalvik".
When that's done Open Odin and put the stock rooted T999 Tmobile Jellybean 4.1.2 into Odin's PDA slot, go into download mode
and once you see Odin is connected to the phone start the flash. Have patience for the phone to boot after its done flashing.
Here is the stock rooted Odin flash T999 Tmobile Jellybean 4.1.2 rom that you can download if you like: T999_UVDMD5
Official JB Firmware - Latest JB 4.1.2 Firmware
My suggestion to you is to only flash Samsung T999 Tmobile stock based Jellybean 4.1.1 or 4.1.2 roms in the future.
But who am I to say whats best..... This is just my personal opinion...... Which usually is not worth a dime. LOL
Sorry, but untill we know more about it, I would not flash T999 firmware onto the T999L.
Its only been out a day and tgey are different model phones with different hardware.
If you decide to try anyway, please post your results

I am a newbie. I thought the T999 was the same as the T999L. That would explain why Odin doesnt flash stock T999 onto my device. Can anyone here post a link to the stock SGH-T999L ROM?
Just did a quick check and I dont see that the firmware has been made available for download yet.
If you want stock I would flash one of the stock based custom roms via recovery for now.
Out of curiosity, what is your current baseband version?

I had the same issue with the same phone. Got it 2 weeks ago haha. Did you happen to make a backup first using CWM Recovery? If so, you can just restore that backup and you'll have your camera functionality back. It's pretty annoying switching back and forth from CM10.1 back to stock just to take pictures but Rom manager makes it pretty quick and effortless.
Actually now that I think of it, they prob wont release the original firmware. Seems like the first build is never available, only when an update is released do we get firmware we csn download.
I am working with another member on getting something going for the T999L, but right now we are stuck until a verified safe method of rooting is found. (Dont want to flash a recovery or cf autoroot w/o knowing it wont screw something up)
Itll happen, but we just gotta be patient.
Just reread the op and see that you say you flashed TWRP. So you were able to initially gain root without any problems?

I used Odin to flash Clockwork Mod recovery first. I did not like Clockwork Mod's interface and reflashed with TWRP. I had no problems to gain root with either of these methods. I also tried Cyanogenmod stable 10.0.0 and then 10.1 RC2 without any problems. As far as I can tell, all apps work except for the camera. One word of caution though. As you can see from my posts, I am new and dont know what I am doing. I might have just gotten lucky since my device is still unbricked. I had only one "scary" moment during the entire process. I used TWRP to wipe my phone clean and was stuck with no OS install file. ADB sideload did not work since it could not recognize the device at that point. Luckily, I had a micro SD card lying around and was able to put in a new OS install file using my laptop and then TWRP was able to handle it.

Wish I had made a backup! Could you zip up the files contained inside "/system/cameradata/" folder and post a link here? It would help me and anyone else with the same problem restore the camera's functionality. In case you want to try it out, follow the instructions in this link but using the files from your stock backup

How did you get Cyanogenmod installed on the t999l every time i try it aborts with status 7
Mine was failing with this same error. I reverted back to stock, re rooted, then downloaded the flash directly to the phones internal storage. Worked like a champ. I think in my case, there is an issue with the SD card, its kind of old.

ALSO AT ONE POINT I DONT KNOW WHAT I DID WRONG BUT THE PLAY STORE WANTS INCLUDE IN THE 10.2 ROM THAT I INSTALL AND THE WEB PLAY STORE WOULD RECOGNIZE MY DEVICE AS NEXUS 7, BUT IT IS A NOTE 2.

downgrade.zip will NOT do ANYTHING to help your issue; all it does it change the files system back to the way it is in 4.12
something else is wrong, but you have to post more info; what rom you flashed, what recovery/version you are on, what the error message/code is when you try to flash, etc...

Thanks even more for letting me know that this won't do the trick. I should start by reiterating that I have a S4 on Sprint and not a Note 2 on AT&T, so I before I get flamed for being in the wrong forum, just wanted to check if I should go further on what I'm running and the "error" I'm experiencing to see if you can help. I'd really appreciate it if you could but don't want to break any rules ...
its not so much about breaking the rules, as it is about giving you advice that could harm your device, since its not the same as this threads'
I would take it to the s4 threads, just to be sure
good luck
So still no luck with this for me. Someone please help. I can only flash non touchwiz ROMs. I am running pacman nightly 4.3 9-7-13 version. I just flashed devil kernel to see if it would fix the issue. No luck but definetly a nice kernel. I try to flash jedix17 16 and even a nandroid I had from 16 no luck. Tried several other tw ROMs but it just gets stuck on bootloop. Hellllllllllp I like pacman but I was flashing roms everyday and I'm going nuts. I brick my gs3 backup phone so I have to be very careful now with only one phone. Advice?????

Okay. ....do you show correct IMEI Number ?
And do you have data ?
If yes. ..then let's try this. ..(deep breath)..(make a backup)...then the following:
First. ...boot to recovery and wipe data, caches, and internal storage. ..
Basically everything without touching your external card. ..and just to be sure. .take it out and set it aside. .(make sure to unmount it in settings first !!!)
Next. .turn off the device and boot into download mode. ..(ready for Odin)
Then using only your PC...download Mr. Robinsons rooted UCAMA4 build from his thread. .. (in the development section)..
Next. ..push the image you just downloaded to the device via Odin. ..(use the PDA box...and don't change any Odin settings)...
Next. ..wait for the image to automatically boot the device once completed. ....(unplug the device)..
If the device fails to boot. ..pull the battery. ..wait 30 seconds. ..then replace it and boot into the newly flashed 3e recovery and wipe cache and data 2 times each. ..then reboot.....
If the device boots normally then move to the next step. ..and if not. ..repeat the flash process again using Odin and the rom you downloaded. ..
If after two unsuccessful flashes, and wipes using 3e recovery, and battery pulls. ..you still don't get a successful boot. ..you may have partition damage. ..in which case a repair may be needed. ..but for the sake of your phone we'll wait until the above has failed. ..
Next. ...If boot occurs using the above method. ..enter your wifi password and log into the play store and download triangle away if you want your counter reset. .
If not. ..skip the play store after entering the wifi password and move into your settings/about phone/software update. ..
Push the update button and wait for ATT to offer you the update to UCAMC3..then take it. ..
If desired you can then clear the flash counter and unroot...
Let's get that far before worrying about anything else. ..
Please record any errors or messages you get. ..especially while using Odin. ..as this tells us the device partition state. ..especially when PIT files are involved. .
Sorry for the long post. ..but it was necessary. ..I hope. .
Please post back. ...g

[Q] Need help. Can't get phone to boot.

Hey all, I've been in the android game for a long time now, so I'm not new to any of this, but this s3 here has me totally stumped.
It is my cousins (telus i747m), and we had it stock rooted 4.1.1 until yesterday.
I updated it to 4.3 with kies, and then he opted for a custom rom. So I flashed TWRP in Odin, and tried to flash gummy 4.4.2
It failed with a assert fail as well as a status 7. I tried old TWRP, New TWRP, Old CWM, New CWM, many different roms ranging from 4.3 and upwards. Still failing with the stupid status 7.
Kies no longer connects to the phone, so I can't restore through there. I will have to install through Odin and the download is horribly and painfully slow.
So is there any way to get a custom rom flashed? I have searched and no one seems to have an answer. Any help appreciated.
What assert failure were you getting?
I'd start back from scratch so go back to stock, then root and flash latest version of TWRP or CWM. Make sure when you flash a Rom it's for that specific device for example if its for the AT&T it's for the AT&T. Also make sure to do a factory wipe before installing any me roms

[Q] Galaxy S3 downgrade from android 4.3 to 4.1.2

I have a T-Mobile Samsung Galaxy S3 (SGH-T999) and I made the mistake of allowing an upgrade??? to android 4.3 which has been very unstable for me. T-Mobile, Samsung, and Google all say that there are no updates to 4.3 and I can’t downgrade, so basically I’m out of luck.
Can I downgrade 4.3 to 4.1.2 without bricking my phone and hopefully without voiding my warranty? If so, please give me some instructions. I downloaded Odin 3.07 and firmware: root66_TMO_T999UVDMD5.7z. Thanks a million.
I don't think it's possible to downgrade anymore due to Knox. There was a thread talking about it

if you flash the root66 of the md5 firmware via odin after you have already upgraded to 4.3 you will HARD BRICK your phone. Taking the 4.3 ota updates your bootloader and flashing anything other than 4.3 in odin will wreck your life.
You need to download the root66mjc firmware here:
http://www.androidfilehost.com/?fid=23212708291682181
And flash it in odin. Then from there install a custom recovery and download a rom of your choosing and the compatible modem. I recommend you download the md5 modem. Then you're gonna wanna boot into recovery and flash the rom and the modem only (kernels are ok of course) JUST NO BOOTLOADERS. I don't even know if you can do that in recovery but trying to mess with the new BL will brick your face I mean phone.
full steps?
so does anyone have any full list of steps and links on where to get the modems and all to downgrade 4.3 with knox down to 4.1.2

I was referring to the 3 persons who responded to the OP's question similar to yours. @jtl_777's response is pointing to the 4.3 Firmware.
Its more implied in this thread than stated matter of factly. This thread is several months old, and I know your question has been asked countless times in many different threads, much more recently than in this one.
I suggest you read the stickies in each section. Just by doing that you will find all firmware and modems and more. You will also find that the answer is no, you cannot downgrade your full firmware from 4.3. And you never will be able to.
If your having problems I suggest flashing the latest 4.3 build via Odin, then factory resetting. Start over clean with minimal restoring of backups (only the essentials).
Every time an update comes out there are people who have problems. The majority are solved by doing what I just said because most bugs are caused by using old data created by old apps on the new build.
Even if you could downgrade, chances are youd run into even more issues and still have to factory reset.

thanks but I read online and some youtube videos showing that people have gone from 4.3 back to 4.1.2, just trying to make the phone the way it was before any updates were done and wondering if anyone knows the proper steps without bricking the phone.
They probably just flashed a rom. It is simply not possible to downgrade the firmware though.

You cannot downgrade your firmware.
Flash an older rom with cwm or twrp if you need to be running md5

so can I use this http://forum.xda-developers.com/showthread.php?t=2276645 and flash via cwm or twrp recovery and it will make the phone run 4.1.2 without bricking or having issues with knox or does that have the bootloader issue with it as well?
Yes, that one you can flash.

great thanks so much for your help, can I flash the recovery via odin mobile app or is it safer to do it via pc?
Safer via PC.
It is possible via Mobile Odin. But that's one of the partitions I don't want to mess with when Phone is Booted/
If you know how to use Mobile Odin then it should be fine. I agree that its better to use pc odin if youre not familiar with Mobile Odin. However, it actually doesnt flash the recovery while booted. It flashes the flash kernel which is MO's temp recovery. It then boots to this and flashes. (So, perseus is right in that regard. But I personally love Mobile Odin and find it extremely useful and consider it safe unless you are brand new to all of this).
In fact Mobile Odin is another way you can flash 4.1.2. Itll flash the firmware, but only the system, kernel, recovery and modem. (I didnt bring this up previously because I didnt want to confuse, or go too far too fast).
If youre thinking about flashing recovery via MO, though, you can also instead just flash the rom you found. No need to flash the recovery unless you just want to. Put the rom in the update.zip slot and itll flash just fine.
If any of this is confusing, just stick with the original plan for now. The rest will come easy if you dont rush things.
One more thing, while you can usually update stock without wiping, you may find you have to factory reset after downgrading as the old system was not built for using data created on a new version.

I have tried so many times to downgrade to 4.1.2 using odin but I havent be able to. I always get an error message

[Q] Samsung Galaxy S3 - T999 - Emergency - Bricked Phone

Hello XDA Community,
Well I am a beginner in terms of trying to utilize anything my T-Mob. Samsung Galaxy S3 has to offer, tried to place CM11 onto my S3 but I think I just bricked my device.
I got to the part where my phone was unrooted and I had all the files ready for ZIP. I actually used TOWELROOT to unroot it, got SuperSU & permissions, I think I may have bypassed KNOX, not 100% sure.
I had the latest TWRP - it boots into it fine but when I tried to install CM11 w/ GAPPs - it fails to install. I keep getting the error that the binary doesn't work. I was reading on the forums that one had to change the d2tmob into d2can - tried it and put the new zip back into the SD card, I even tried to put CM10.2 thinking that maybe the "stable version" might be better than the nightly.
Anyhow, I was following a guide and I deleted everything (INCLUDING MY OS) except for things in my SD Card.
I cannot recover anything because I backed up my phone onto my phone - which was wiped...real genius....
I am kicking myself, I haven't been able to use my phone for 4 days now, I've been trying to fix it myself but I have NO CLUE in terms of what to do next.
I keep reading about ODIN and booting something else but I am extremely distraught over the whole ordeal and I do not know what to do.
I can boot into download mode (down button + middle + power) but my skills are extremely rudimentary - I am sorry to bother the community but I really do need help.
I have trouble understanding any difficult things - I kind of need the instructions to be broken down to like "Plug phone in now" - do that...and etc. Any links that might help are muchly appreciated.
I just want any OS now - even if it is stock but I need simple instructions ~ I am sorry, I really do not know where else to turn to....pretty sure my phone is bricked (soft bricked, idk) - but I do not know where else to turn - please help XDA community.
So if there's anything someone could dig up or do to help me fix my phone....I would be eternally grateful.
Download the stock or root66 firmware from my thread stickied in development. I suggest reading that and other stickies as well btw.
After downloading, unzip. The result should be a .tar.md5 file.
Boot download mode
Plug in phone, open odin 3.09. (Download in my signature)
Click AP and select the firmware you just got.
After the check finishes, click start. When it says PASS it'll reboot and you're done.

Thank You so much for the prompty response, downloading the root66 now,
I hope it's okay that I do not have any OS on it. I will definitely let you know how it goes.
Quick Question: download mode is Down Key + Middle + Power.
And AP should be in Odin right?
Also...for the boxes - what should be checked in ODIN 3.09 when I am about to put in the AP thing?

it worked! Thank you so much!
Awesome! Glad to hear it! Sorry I didn't answer your last questions in time, but for future reference, only F-Reset Time and Auto Reboot should be checked.

No, I am so grateful!
I was wondering if there might possibly be a guide to properly get CM 11, I will definitely look for it. Thanks

Okay, so now that my phone is back on Stock (I used the root66 method), I have SuperSU but when I go to the app, it gives me the message
"if you have a custom recovery like TWRP or CWM, that can be used to install the SU binary. This is recommended for HTC devices. How would you like to install the SU Binary, with Normal as an option & TWRP/CWM as another option.
I am trying to see how to properly root my phone in the next step.
After I root my phone, I hope to get flash a ROM.
I am sorry to ask again DocHoliday77 but could you please help me once again in terms of what to do next?
I think your instructions were really simple (layman's terms) and it helped me debrick my device.
I just do not know how to flash a ROM, let's just say for purposes that I wanted the Carbon ROM - how would I proceed once I get to the step with SuperSU's message? Please help
If your intentions are to flash a rom, you don't need to be rooted before hand. Just boot into twrp/cwm, factory reset and flash the rom. That's it!
As to your specific question, I always choose Normal for that option.

Just a heads up, I hear they may have solved it, but the latest cm roms haven't worked well without the 4.4.2 modems. If you flash and find you have signal/connection/imei issues, factory reset and flash an older version.

Seems like a silly question but how do I get CWM/TWRP?
I had booted into TWRP before but I kept getting the binary updater error when I tried to flash CM11.
Is there an easy way to get CWM - I think that would be my route of preference now because of the sour experience with TWRP.
here is a link to CWM advanced philz touch recovery. its CWM but with xtra options and you use 'touch' instead of volume buttons.
if you want to check it out.
its a flashable zip.

Thank You very much. I'll try to follow the instructions.
And my SuperSU popup never came back after the first time - I do not think it is working properly

Sorry, was just reading up on how to flash PhilzCWM with a GS3-t999 but it seems a bit complicated.
I'm sorry, I am extremely computer illiterate and I have to apologize for that.
My goal is to get a custom ROM - I already have the ROM I want downloaded and such but I just do not have anyway to flash it.
Is there any easier way to get to where I want to be?
Please let me know & if you could provide simple layman's terms, I would greatly appreciate it.
Thanks in advance.
if you can get to cwm recvery to flash a zip file , then
https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
the 2nd zip file from the bottom is the latest i believe. (philz_touch_6.486-d2lte.zip).
click on that and it should download to your phone. then go into CWM and choose that file to flash. reboot phone. then go back into recovery and you should now have 'cwm advanced philz touch recovery' on your phone.
then you can flash your ROM from there.
hope that made sense.

Can you tell us exactly what recovery you currently have? Twrp/cwm/philz should all work fine. I use twrp. Just personal preference.
Also, go into Settings > about device and tell us your current baseband.

twrp for me also doc. feels more user friendly. (just my opinion) still on v.2.6.3.1 d2att and no problems. just saying.

Hey I finally installed a custom ROM onto my Galaxy S3!
I just used TWRP and flashed it. I've been messing around with all the combinations so far ~ it's really amazing, it's like I have a new phone.
Quick Question: say I wanted to flash another ROM, other than the one I am currently using.
Can I just download another ROM onto my SD card and flash it via TWRP again OR
Do I have to restore the phone back to it's original stock OS and redo the TWRP thing again?

Sorry I haven't replied sooner. Haven't been home this weekend.
For the most part, yes, just download the new rom and flash. No need to revert to stock or reflash recovery except in certain situations.
Unless you are flashing a very similar rom, it's always a good idea to factory reset. You can get away with "dirty flashing" sometimes, but if you have problems, youll have to reset.
This is required if going between different based roms such as Touchwiz and cm.

Hi, everybody!
The minus page says that the file is not avaible or does not exist, when I try to download the original ICS Rom of the T999 T-Mobile.
Please, fix this!
Thanks!

I don't recommend installing a stock ICS ROM if your phone has a 4.3 bootloader.
Yeah I did the ICS on the 4.3 bootloader. Don't do it, it hurts......
