How to go back to stock?

Yes I have seen guides but none that applied to me. I used the method drockstar posted using ginger break and his clean kernal and I didn't need a pc to root. I have to turn my phone back Into my company for some software updates so need to go back to stock. I can't not loose som of our software that's currently on here. I do not have access to a pc either so I need to do it all on my phone. Any one have a link to how to do this? Thanks

If you are on a Gingerbread leak and also changed your modem, you will have to Odin in the EC05 modem, flash ReRFS ROM and flash stock recovery. You are always taking a risk of losing all your data this way. If it is a company phone you shouldn't root it. Go into Development and search for ReRFS ROM.

I just used the Gingerbreak to root and then added he DRockstar kernel
Thanks

is it possible just to flash a stock kernel and then do the ota update and then turn my phone into them for their updates?

even better I will have access to a PC tonight and I have a cord so I could use odin etc.. what will I be able to do and not loose info on phone. thanks guys. I been reading post after post. how do you guys sort though all this info and make any sense of it.lol

Sorry to say it but if you use odin I really don't know if there is any way to save the data. If I'm wrong someone please correct me. I know how you feel as I to had to turn my phone in and lost everything including company software (didn't get into any trouble since the boss had me root his phone and he also lost all the data lol). Hope somebody can help you out more.

To use mobile odin you need to download the tar file and not the zip file. Then you need to use open file in odin and find where you put the tar file. What ROMs were you trying to download?

Mobile odin is just like the odin. Only the difference is the platform where it's running. If you downloaded a rom, be sure it has the format which can be recognized by mobile odin. The zip file format which is only supported thru CWM recovery, can not be odined by mobile odin.
If mobile odin cannot locate the rom, it means it simply means that it's not supporting the file that you downloaded.
Be sure that, current mobile odin on ICS, it does not odin the Modem part.

Calkulins the newest one i want to try cm9 idk yet i got stock fc24 and want something different how do i download the tar and not the zip i just checked my files it was the zip lol told u im a noob :screwy:
Sent from my SPH-D710 using XDA

cm9 is not available as a .tar.
To install cm9 you will need to follow the instructions listed on the cm9 installation page exactly, as flashing using the wrong recovery could lead to a brick.
Just a suggestion. As a self described newb, slow down, read read read. There is nothing so amazing in any ROM that is worth running off Willy Nilly and flashing foolishly.
Don't take my tone as harsh. Buying software and not reading as to how to use is a clear sign that you aren't ready to flash. Too many folks have bricked by being impatient.
Read the forums. Read replies. Read, read, read.

Advice - READ A WHOLE LOT. You will most assuredly turn your phone into an expensive paper weight. Or at best end up with a poorly functioning device and bad experience. I understand your excitedness but spend some time - a week or two (minimum) researching and reading these threads and others. You've already managed to get a pre-release build on it. That's good (and bad). This phone is incredible. If you spend the time to understand it you can make it even better. Good luck

Dont worry no offense taken i did read i guess i just didnt understand that u needed a tar and knew u couldnt flash cm9 on odin i got fc24 with no issues i understand directions im not completely illiterate lol ha ha... I DOWLOADED EL26 TAR AND GAPPS AND CM9 IM just trying to ponder which i wld like sorry i confused i unferstand the potential hazards... Bricking etc... I just like the idea of being able to customize my phone :thumbup:

Glad you weren't offended, wasn't my intention.
Just be careful, hate to see you added to the brick list. If one of the devs can brick, then its clear anyone can if not careful.
Good luck guy.

By the way, once you get used to it you will find Mobile Odin worth the money spent.
I keep the EL 26 (think that is the one) .tar on my sd card, before I flash from one version (I.e. gingerbread to ics or ics to cm, or any combination) I use Mobile Odin to flash 26 first. Once phone rebootsd I hold volume up to get into recovery. Get caulks wipe file and flash it, then whatever you want.
Should be able to find those files in the dev section, if not shoot me a pm and I will provide them.

If i stay on my stock fc24 build and the official ota comes do i just go back to stock gb el29 to getvthe ota then thanks in advance and im gonna take ur advice and read i was just antsty and wanted ics now i have it and got greedy i will read first :thumbup:
Sent from my SPH-D710 using XDA

Once the ota hits I would just wait for the devs to get a hold of it, then get it tweaked, rooted.

Glad to see you are learning and using this thing. My reason for saying 'good and bad' is a little knowledge can kill. You've probably seen the posts and comments on bricking so you know it's possible. If very experienced developers (like the guys building kernals and repacking ROMs) can brick their phones, imagine how easy it is for us 'regular' folk. My advice is to try a few different setups over a few weeks or days and see what works best for you. Just make sure to follow the installation notes as carefully as possible. As was mentioned Mobile Odin is money well spent and I too keep stock(rooted) tars on my SD card for recovery purposes. I've owned a sh$t load of phones and smart phones and this one is hands down the most customizable I've ever seen. Be careful, have fun and good luck!

[Q] Coming from OG Evo to E4GT

I purchased this phone yesterday after a great year with my Evo and two with a Hero before that. Even though I haven't posted alot I've been rooting and customizing my phones for years. I was even to the point with the file system and stuff that I would add and remove things from roms before I flashed them so I feel like I know what I'm doing with an Android phone.
This thing is a whole other animal though as far as I'm concerned. I've searched, I've read and I still don't understand half the lingo used here. I don't even know how to ask the questions I want to ask honestly. I hate having to jump through hoops just to flash a ROM.
I am rooted. Baseband is el29, kernel is 2.6.35.14-rogue_ET-1.4.1+ and build is Calkulin 3.0. I installed Rom Manager from the market and got the official Clockwork Mod Recovery because I didn't like the recovery that was put on my phone when I rooted.
So from here with the setup I explained what roms can I just place on my sd card and flash through recovery after a wipe? I don't want downgrade to a previous anything or change a modem or use Odin because I don't know what any of that stuff means and there is no where I can find that it's explained very well.
I appreciate any help that is offered and I know I come off as negative but so far this phone is extremely intimidating to do anything with and I don't want to brick it. I never worried about bricking my Evo cause I'm not sure that's even possible anymore

I worked on a friends EVO once and didn't understand half of what you guys had to do to root and flash so the feeling is mutual, lol. First off if you're going to switch to ICS start on the EL26 kernel with CWM. Anything else and you risk a hard brick. Odin is actually the easiest to flash with. Sfhub has Odin one-click that makes it easy as hell.

And here's a really good how-to: http://forum.xda-developers.com/showthread.php?t=1391732
And download mobile Odin, DON'T use ROM Manager. That will almost certainly brick your phone. Just delete it to be safe.

one of the things you're going to have to get used to with this phone, is that the kernels and recoveries are tied together. Its not like any other android phone i ever used that you could swap out kernels and use whichever recovery you wanted.

You have a Samsung phone now. You are in the promised land. Samsung phones are a lot easier to work with than HTC phones.
Basically any ROM here can be flashed using Clockwork Mod Recovery unless it says otherwise. I'd like to point you over to QBKing77's youtube channel. He has a ton of "how to's" and reviews for a lot of ROMs on the E4GT.
http://www.youtube.com/user/qbking77
I'm sure you'd appreciate that. My family uses HTC phones and whenever they want something done to their phone, I tear up and hope that QBKing77 got an EVO since the last time I needed him.
Also the great thing about Samsung is that if you do happen to brick your phone, Odin will save your life.
If you have any question feel free to PM me or something

You cannot use a GB kernel with an ICS ROM and you cannot use an ICS kernel with a GB ROM.
Coming from stock EL29 you can use the Oneclicks to upgrade to the newer FD ROMs or just flash most through CWM unless they state otherwise.
If you do decide to go ICS(FD24 FD26 etc) and want to go back to GB ROMs, you need to flash the EL26+CWM through Odin(which isn't as complicated as you think) and go right to recovery as the phone tries to reboot, then flash the GB rom.
Seriously check out qbking though, he is the biggest help and his videos are phenomenal. Hope that helps a little.

You need to used Odin to flash EL26+cwm.tar. However, you do not need a computer, I use mobile odin android app religously. It is definitely worth the 5 bucks. For mobile odin just keep the EL26+cwm.tar on your phone, when you want to leave a rom open mobile odin app, point it to that .tar and flash. Then you will have the best copy of cwm on your phone and can start wiping/flashing any roms, kernals, or modems.

You can nandroid right back! You will have to have a kernel that will let you use CWM such as FD02 or EL26 to get to recovery for the nandroid.

Thanks for all the help but I'm strongly considering returning this phone. I've read till my head hurts and the most common words I see here is brick. I don't want to take that chance. How anyone could think dealing with an Evo is worse than this I don't understand. With the Evo you put the rom on the sd card, wipe, and flash. No worrying if you have the right modem/kernel/cwm combination. It's a nice phone, but I really regret buying it now. 3g is also slooooooow.

I also recently moved to this phone from the evo. The epic touch blows the evo away in every way possible! There is definitely some studying to be done but its worth it! Once you get the hang of things its a breeze.

Same here. I've had the phone since latter part of December and have not rooted it yet ...mostly because my laptop has the screen of death.But noticed the slight difference in the method in flashing roms on the E4GT. But after seeing some video on that AOKP rom I'm getting antsy and need to get my computer fixed!!

Rooting a sph-d710 already updated to ICS via OTA

I have an unrooted Samsung Galaxy S2 Sprint version that I never rooted, and I just updated to ICS stock (over the air update). While I had rooted another, this is my wife's phone and I want to root it to get better control over the battery issues. I read the wiki, but it all was dated to before the update.
Do any of the rooting methods work once you have already upgraded to the latest ICS update that came from Sprint?

I am unsure of the rooting methods at this point. Did you check the one click rooting sticky? I would put the phone in download mode and odin a rom of your choosing (like el29 from sfhub) then one click root, recovery and flash a rom of your choosing. This process is of course only if the existing methods don't work with the OTA.

You have to remember that even though you are saying you are a noob it does not mean that you should not read, read, read and then read some more. Honestly I have no problem with your questions but if you took some time to read stickies and info in the forum you would have found the answers to your questions. Also a Google search referencing Wifi Hotspot and not being rooted would of taken you to FoxFi. I suggest you give that a try prior to rooting if thats all you really need.
Remember either xda or Google is there to help you but they can not if you do not ever use them properly.My last piece of advice if you are not one to do reading or not one to really want to take risk. DONT ROOT try FoxFi or the host of other tether options that dont require root

I second using Febby's method - that's how I would do it. Its the scalpel vs. ax analogy - Febby uses a scalpel, those who re-flash an entire rom use an ax. Both work if you follow directions.

Only down side to febby's method is yellow triangle. It is easy to get rid of any way.

OK,
You are another admited nooby, and that is OK.
However please, please take some time and read throught the stickies, how tos and follow up posts to the Original Posts.
You WILL save yourself a whole lot of time, frustration and possible flaming.
If you want the latest JellyBean Stock follow the insturctions here. They are detailed and precise.
It is the one-click root method that will give you the ernel, ROM and Modem in one shot.
You will NOT have a custom recovery (with CWM) and will NOT have the yellow triangle.
Not that you must run the one-click 'as administrator' first AND put your phone into download mode before before plugging it into the PC.
If you want a custom recovery (Garwynn's or Agat's) then you can keep the yellow triangle away by using Mobile Odin Pro. BUY it in the Play Store. Download the custome recovery of your choice and open Mobile Odin, Select Kernel, navigate to the .tar file you've transfered to your SD card and 'flash firmware'.
Really though please take some time, don't be impatient. It can save you making an expensive paperweight and have a taste of sh%t in your mouth.
Good luck.

Thanks!

You will NOT have a custom recovery (with CWM) and will NOT have the yellow triangle.
Not that you must run the one-click 'as administrator' first AND put your phone into download mode before before plugging it into the PC.
If you want a custom recovery (Garwynn's or Agat's) then you can keep the yellow triangle away by using Mobile Odin Pro. BUY it in the Play Store. Download the custome recovery of your choice and open Mobile Odin, Select Kernel, navigate to the .tar file you've transfered to your SD card and 'flash firmware'.
Really though please take some time, don't be impatient. It can save you making an expensive paperweight and have a taste of sh%t in your mouth.
Good luck.

Thanks. Your link is the link that I list at #5, above. I took the time to read through many many threads on this, but with so many unfamiliar terms and procedures, I wanted to make sure that I was following the method that will get me the results that I am after. Thanks so much for the confirmation!

4.1.1 S3 Simple Root

Hey everyone, I updated my T-Mobile S3 to 4.1.1 when it came out two weeks ago and my phone was rooted on ICS. I had already downloaded the stock firmware to use with Odin before the root66 firmware was uploaded here. I was too lazy to redownload it so I figured I would just root after I updated to JB. I realized the toolkit that I used to root in ICS does not work in JB and after looking through the forum it seemed like the only way would be to push the root66 firmware in Odin. The thread that shows how to use the roo66 says that its used if you don't want to void your warranty and if it does not matter there are easier ways to do it. So, is there a faster way to root the T-Mobile stock JB or would I have to use root66 with odin? Also, when I pushed the stock JB using odin I did not lose any data on the phone, I know it's probably the same with the root66 but I just wanted to double check with you guys if I would lose any data after pushing the root66 firmware using odin. All help will be appreciated. Thanks a lot.

No you shouldn't lose any data, but it can happen. Always backup first!
Root66 imo is the easiest and safest way. You can check out cf-root in original development too. Never used that one though.

Thanks Doc. Also, the only real reason I wanted my root back was to use the Wifi Tether app. It worked well on ICS however I heard people were having problems with it on JB. Do you or anyone else know if it works or not?

It has been confirmed working, but Tmo has also been blocking tethering on more devices.

Search xda for treve tether. He's released a mod that seems to have a very high success rate.

download an app called easy tether. easy as it gets right there man, the app will walk you through the setup... when you get to the part when you need to find out what version of windows you are on (if on windows), open your start menu and where it says "search programs and files" type: dxdiag
your system info will pop up. on your way
as far as the rooting method, honestly, i think CF root is the easiest way. it's just booting into download mode and navigating to the .tar.md5 file... he wasn't joking when he said it literally takes 30 seconds.
and that easy tether app, does not require root access. so go ahead and download it naaaoooo
good luck bud
