I originally posted in the wrong area, and was told to post here instead so, here goes. I have a US Celluar GS3, SCH-R530U, and I lost root access while trying to upgrade from stock rooted 4.1.2 to CM 10.1.3. I've tried flashing SuperSU along with CM 10.1.2 to my phone with no success. Every time I try to flash something new it says 'Can't open /storage/sdcard1/-filename-.zip (bad)' and it aborts. I don't know how I can get a file on the phone memory since the phone never boots up past the 'Samsung Galaxy S III' screen, so I'm really stuck and I don't have a backup phone, so if someone could help me get my phone up and running again, I would really appreciate it.
Original Thread
I really only need help getting my phone to a bootable state again, I have backups of everything, so if someone could please help me out, I would be most grateful. I've been trying dozens of things. I just tried doing CF Auto Root through Odin, and that didn't work, it just removed CWM. It still freezes up at the same screen, so I'm really lost as to what to do.
My best advice would be that you download the Odin file that matches with your phone. But get the fully stick one. There should be one that is rooted and non-rooted. Get it back to stock and start from scratch. I know it may suck but honestly in problems like this it doesn't hurt to go the safe way

That would not be a problem at all, in fact, that is what I would love to be able to do, but I haven't been able to find an image file for odin to do it. Every image for a stock rooted file for my phone is formatted for CWM, and it won't flash anything from my sd card right now. If I had an odin image, I would do just that.
Found one and flashed it. It's sad to see everything on my phone get deleted though.

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.

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.

Before you guys read this thread, let me just go ahead and say that i AM in fact a XDA noob... so dont hate. I didnt come here for that, but i came for help. Now, i did notice that there were alot of people having similar problems as i was. And yes, i did read all those threads. BUT, the only difference was, they got that error while trying to unroot. I was trying to root mine. I simply tried flashing CWM (and yes i made sure it was the correct flash as well) and it failed. Tried rebooting the phone, and i got that error. I am honestly freaking out right now as to if i have lost my phone or not, so i wouldnt appreciate hate in the comments, that would not help. So please help if possible... Is there a way to fix this?
We're you on stock Rom. How did you try a put CWM on your phone?? Odin??
Best way to install a recovery is Odin or goo manger!!
If you can get the phone into download mode then you can just flash back to your stock firmware...
Unless you flashed the wrong recovery on your phone. Then your in store for brick city.

thanks, i was actually on odin. But i think i found the solution. You see, when i was trying to find a solution on my own, i accidentally ended up installing a verizon rom on my phone which is att. (i didnt know it was verizon) The rom works, but i cant use mobile data, because its not a verizon SIM card. However, i managed to install TWRP recovery with goomanager, and from that i will attempt to install the JediXP14 custom rom. Strangely, it seems the phone is rooted even though i was told it failed. I will let you know on the progress, should be done in an hour or so.
Oh boy..... I smell brick city.. You better be careful what ur doing with Odin... If u are flashing stock firmware in Odin it flashes the radio with it....
Ok guys, i SOMEWHAT resolved the issue. But there are alot better ways of doing it, i was just forced to do it the following way:
The only flash rom i could get to go in through odin was a Verizon rom. It was basically the stock Note 2 rom for verizon.
Now the only problem with this, is that obviously, my phone is ATT and this is a Verizon rom, but it WILL work, but with an exception. Wifi and all will work, you can call and receive messages, but you cannot access the internet via mobile data. So that was another issue that popped up. I tried flashing an att stock rom through odin, but it stayed stuck at "Setup Connection" so that didnt work. The only solution i could think of was to unlock the rom, so i could use data with my ATT sim card. Strangely, the phone thought that it was a Verizon phone when it was an ATT phone, so that was the only option. It required a root but that wasnt a problem. I installed Hidroid off the play store and unlocked it that way, and now everything works fine. There is still an error message in the status bar saying "Non-Verizon SIM" but despite that message, everything still is in working order. If anyone knows what to do once you first get that error message, you could post it below for anyone else having the same problem. And if there is a way to change it back to the normal ATT stock, that would be appreciated as well. Thanks

Maybe you just need to flash att modem with ril for your device. Scroll down and dload the one for att then flash using cwm or twrp. After flashing modem try flashing att rom again via Odin.

Ok guys I resolved the problem. But it took more steps than it needed. This is for people who accidentally flashed the wrong type of recovery to your phone (example, gt-1700 version of cm what on sgh-I317) I'll be renaming this thread if I can. So here's all the steps I took. Now keep in mind that I didn't exactly know what I was doing so I kind of learned on the way, like I said in the beginning of this thread, I am a noob, and I admit such.
1. Install any rom that is in md5 format (preferably with your carrier modem but anything will do) I used a verizon rom. I can't exactly provide a link given my user status though, but I will when I can.
2. If you don't have wifi and downloaded rom under incorrect modem, then download hidroid on the play store and unlock it. It should be simple once getting the app. This will allow you to use mobile data. You'll need it.
3. Download goomanager
4. Press menu button
5. Install open recovery script
Now you should have TWRP installed on your device.
6. Install any custom rom compatible with your device, but make sure it comes with the correct modem as your phone originally had.
7. Flash it through TWRP (make a backup first)
You should be done from there. Now I don't recommend this. There has to be an easier way, so it would be great if anyone could provide that below. But the steps above are the steps I took. Thanks

Umm guys, i ran into a similar problem. Where would i find the att rom to flash from odin?
So, today I flashed MIJJz Goodness Noteworthy 1.0.8. Everything went well. I also changed modems to JC1. Didn't like the rom (personal opinion) and tried to go back to stock. I went through Galaxy note2 toolkit initially and failed. Tried the old fashioned flash and failed. Tried the oneclick and failed. Every time the phone fails to go back to stock the only way I have been able to get it to work again is by using odin to flash boot-stock-alj1-SPHL900.tar from my galaxy note2 toolkit folder. the rom is still there.
So as the title states, lets assume I'm completely retarded.....can someone please hold my hand and walk me through returning my phone to stock?
Update: In addition i have flashed twrp, wiped everything, and attempted a stock flash zip from sd card.....failed. if i do the same for the goodness noteworthy rom.....success. i dont get it.
Update: I have attempted another rom (Illusion) and no dice. It seems I'm currently stuck with Goodness or nothing.
Update: I have made sure that no boxes were checked in TWRP settings. All attempts to flash fail except for the Goodness Noteworthy Rom.
[PROBLEM SOLVED] The issue was that my Odin version and drivers version was too old. I updated both and the flash worked as advertised.
Have you tried the return to stock zip that unroots resets flash counter and installs stock rom?

I am fairly certain that I have tried that, but for the sake of being thorough, let's assume that I have not. Could you please point me in the direction of this download? I'm going to take the "ultra dummy approach" because chances are this problem has more to do with the operator (me) than with the software.

So, a while back, i decided to convert my ATT galaxy s3 to a tmobile build so i could run LTE from tmobile on it. Now, my problem is, i want to revert back to full att again, in which i have tried, but im getting something wrong (Status 7 errors and what not, i feel related to the changeover) and i don't want to brick my phone trying over and over. I could use some help with what ill need to FULLY get back to at least stock so i can root and install a fresh kitkat rom. Any help is appreciated!
I attached a screen of my build as well.
How exactly did you go about this? What were the zips you used to do this? What zips are you trying to flash? These are all things that can help us out in figuring out what went wrong.
Well i had read around of a test rom created especially for tmobiles GS3 variant that ran on att in order to run their LTE. So i flashed that rom and i believe custom kernels and a modem. Only thing is i cant backtrack what i did and the original files i used are lost.
Anybody? Hehe I really need to get to a computer soon ..
That's an easy fix.
Odin back to a stock 4.1.x, rooted or unrooted.
Then on first boot hold volume up + home button and to a factory reset. Done.
PS: make sure you're not running 4.3 OTA latest bootloader or you will get a semi reversible brick.

Well I give up... I have finally done something that I can not fix. I can normally google and find my own answers and I never have to ask anyone but this time is different.
I have the I317 Note 2, Everything was fine, I was running a stock rom earlier this week and the phone started acting funny. So I though screw it, Ill just go back to stock. So i downloaded.KIES_HOME_I317UCALJ2_I317ATTALJ2_215287_REV04_user_low_ship.tar and used Odin to flash the stock firmware. I DID do a full wipe before I went back to stock. It worked fine for 2 days. It kept wanting to download an update. So it did. When it restarted from the update that the phone downloaded it got stuck on the Samsung screen.
I thought no big deal, I will just reflash the stock firmware and start again... FAIL same thing happened. It wont get past the Samsung screen even after leaving it on that screen for a hour. So then I tried to get into recovery... it wont let me.Then I reinstalled the stock rom and waited for boot, then I flashed CWM and tried to get in to recovery that way. No luck.
I feel like I need to do a wipe and start all over but I cant figure out how to do a full wipe without recovery. There has got to be something easy that I am missing but I cant figure it out. I will keep on searching with hope that someone tells me what I am doing wrong or what to do.
THANKS
If its still able to go into download mode and odin recognizes the device your good just be patient and download the correct firmware.

There are some issues with the OTA update from LJ2 to MH3, which it appears you still have sitting on your phone. You can try booting recovery and clearing cache - that should get rid of the OTA file.
The thread below has some information on how to update from LJ2 up through MH3 and then MK6. It's intended for those who already have the MK6 bootloader - if you don't already have that or want that, you'll want to stop at MH3 and consider your options.

Do you know did I use the correct firmware? I have had to run Odin a couple of times before but its a no go this time... I can not get into recovery. Even if I run Odin now with TWRP and restart it still wont let me into recovery... Can I use Odin to to a full wipe?

One that would work.... LOL I really dont have a preference other then I did not care for 4.3 I ended up with 4.1.1 and I couldn't be more happy. If they ever get 4.4 I would try that.
Its funny 4yrs ago I had the Sprint Evo. I changed roms more often then I changed shirts it seamed. I never had the issues or anything like what I ran into yesterday. I was so careless just trying every rom that was released. Because of that I will always remember the EVO as my favorite phone.
Those were simpler times...
I assume you want root and know how to get it.
Since you have the mk6 bootloader you will need to avoid odin flashing any packages that contain bootloaders in the future. See my mk6 thread for details.
If you want to get to 4.1.2 there are rooted cwm packages for ma4, mc3, and mh3 available. Wherever you end up, I recommend freezing the AT&T Software Update apk from within Titanium Backup or equivalent to ensure that you don't get a forced ota update at some point in the future.
