So, I was approached by someone asking me to take a stab at repairing their phone. They have a Sprint SGS3, and the owner is, well, less than versed in reading through XDA and determining exactly what steps they've taken to modify their phone.
Suffice it to say, I have a bit of a diagnostic challenge on my hands.
Their story is that they rooted and installed a custom ROM on their phone, and has apparently spent the last week or so fighting with their device to return to stock. I've been told that the ROM is stock, and the recovery is also stock. They apparently want to return to stock and take the KitKat OTA, and have nothing to do with rooting. Though, House says, "everybody lies". I'm assuming there's something else I should be looking at to check whether or not they're deliberately omitting a step they took, or perhaps something they didn't realize/forgot they did.
I have yet to get the device in my hands, but when I do, what should I be looking for, exactly? I haven't modified many Samsung phones in the past, mostly just HTC devices, so I'm not sure what I'm looking for. Poking around the forum, I see some mentions of a Flash Counter and ODIN and some other utilities, but I'm not sure what I should really be using to try to fix the phone. I'd also like to maintain the ability to root their ROM in the future if possible, just in case the owner goes back on their root-bashing.
Thanks for reading! If you guys ever need a hand with an HTC device, I'd be more than glad to give you a hand there. :laugh:
If they're on a stock ROM, you could hook it up to Samsung Kies and do a "firmware upgrade and initialization" under the Tools menu. That should restore a completely wiped stock ROM w/ stock recovery, as well.

The bootloader will still read at modified status, and if your acquaintance's phone has Knox on it, I wouldn't try the flash counter reset.

Okay lets say im on stock everythings 100% stock and i want to flash a custom recovery kernel that has init.d support, custom boot ani support, and add blocking ect..... ok so i flash it lets say........then i lets say i revert back to my stock recovery and kernel......okay now here is the question.......is there anyway i can clean up what the custom kernel installs? Is there a need to clean up? I want to add my own tweaks so i dont want anything bumping code or have multiple code in my phone i want it nice and clean.
Thank you
Your question is confusing but bottom line if you want to start fresh do a clean installation.
Why anybody here would want a stock setup is beyond my comprehension.
Exactly my point i want it fresh and ill do my own thing but i need these custom recovery kernels to gain root or when i need to flash a zip in cwm so after im done kernel riding somebody else is work please take all the belonings with you brought with you when i flash you out. Its in view of my comprehension that these builds dont have a fresh way to gain root access for example like using one click root or an apk to root. they made them in the past before for us sgs2 users.

Use a pre-rooted Odin one click and you get root w/o recovery. There are rooted 1clicks all the way thru fi27. If u use a no-data version all your apps and settings will remain after flash.

Ok now I understand a little more what you want. I think you should spend more time reading and browsing the development sections for more info. I think Agat63 has been packaging stock kernels lately for those who prefer this.
lol yea.. theres plenty of ways. ifor one use mobile odin whenever i need to fllash a kernel.. you can switch between all the kernels you want and maintain root

Just want to say this my first time rooting a device etc, this is pretty new to me. So I followed the steps in this thread to root my totally stock Sprint LGOG ZV9. I rooted with no problem. No I just want to know do I need to backup my current config, what software would I use. Also was the boot loader unlocked. I Just want to make sure that I do exactly what is supposed to be done correctly. Are there custom roms for lgog currently.
Just an image showing phone was rooted

I am assuming this software was installed when I rooted the phone

Oh just figured Id show some great 4g speeds I get from Sprint at my house !! These speeds are very consistent at my house and you can see there isnt anu WIFI on just my Sprint Data. I am moving in the next month or so though. Its crazy where internet speed has come in the last 10 years.
4.1.2 Jelly Bean has been released for this phone now, I'd start by getting that. check out the LGOG development forums to flash a stock version of it or I think Lifeless ROM also has Jelly Bean incorporated now.

After rooting you can choose to unlock your bootloader to flash better code or custom roms to your device, or download and run apps that would require root like root explorer or setcpu to change how your device works.
Unlocking is a whole different ballgame. It allows to flash custom kernels and roms. Like spatel said, 4.1.2 is out and if you unlock and flash TWRP or CWM, you can make a backup of your current phone system, data, efs, cache and then flash 4.1.2 to your phone to see if you like it or not. You can flash the new ZVB radio and possibly improve your signal. It all depends on what your comfortable with. Also, it depends on your interests and whether you're into theming or developing and rooting is just one of those precursors.
Currently there are a few roms based on stock but some AOSP roms will follow now that some source is available to developers. From what I understand, the efs contains important device info and is currently breaking with AOSP roms attempts but I'm sure the devs are making progress on it. If anything check the threads and stickies for a lot more info. There's a wealth of info out there and Google is your friend lol

Thanx for the info
Hi all, I rooted my S2 a while back and am looking to un-do everything and return to stock. Have had way too many issues and am far too busy with work and my son to do the proper research as far as debugging and etc.
I have the Virgin Mobile S2. Android 4.1.2. Baseband- S710.10 S.GB28. Kernal version- 3.0.75+ AGAT GB_27_kernal #v1.4.2 SMP PREEMPT Thu Jun 2 and am on Project X v3.1
I just want to completely return to stock and then I am going to re-root and stay stock with no custom kernal or ROM. I have lost my backups. I don't mind starting from scratch. Any help is MUCH APPRECIATED. Thing is just buggy as hell these days.

So, Just to be clear, I can simply flash any stock rom from where I am now and be good to go?
Well obviously I don't want ANY. I will use the Stock GB28 Virgin one. But that is all I have to do, correct? Just go into download mode and run the one click that I get from the link in that post? And *poof* I am back to being completely stock?
Sorry but I am a noob and this phone's development is way over my head. Just wanna get this thing back to how it was when I bought it and leave it alone lol
I am so sorry to be a nuisance. But if my assumptions are correct, When I go to download the one click there is one that says rooted and one that says unrooted. I am currently rooted. Does that mean I click the rooted button? I am just confused as to if it says rooted bc it is for rooted people, or bc it is for people who want to be rooted lol last question I promise. I am ready to get this over with!
SUCCESS.
Sorry, I was at work. Glad you got it.
No problem! It's amazing how much better my phone is now. Makes me want to try flashing something again because I must have had a bad flash or something. Really everything worked great besides my camera but with a 3 year old son, having no camera is a big no-no for me! It was really strange.

Just released a new one
In the last couple days I ended up moving my way up the Stock firmware going from N900TUVUDNE6 4.4.2 w/ root Knox in tact to N900TUVUDNF4 4.4.2 w/ root K.I.T. Within the last 24-hours I was tinkering around with the ROM and I cannot believe I was so derpy but I made a few changes with some apps and ended up doing a reboot. Well when I went to reboot the normal first boot screen came on

(mine is the N900T, I pulled the image from a google image search) and it goes blank after that. I can get into Download Mode and Recovery no problem, and I almost feel like if I just try to re-flash the stock firmware I will be good to go again. My biggest concern about doing this is losing my root and I wouldn't very much like that simply because to get it back would mean tripping Knox. So, I guess what I am looking for is someone who might have a stock System Dump of the N900TUVUDNF4 with root. Even better if it were in a flashable format for Odin or Recovery. I'm also open to suggestions to other-work arounds. I've tried reflashing bootloader, CSC, modem, non_hlos, and recovery with no luck. Before updating the ROM I did to a factory reset so that it cleared all data for a fresh install and have since cleared data/factory reset and clear cache. So, like I said, I am open to suggestions ideas, etc. I've done a lot of research and tinkering around trying to figure this out, but it finally came down to needing to reach out to someone.
Additional Info:
At one point I was getting ADB when it was sitting on the black screen, but now I can only get ADB when I choose update with ADB in recovery, otherwise Odin is picking it up.

you start with nf4, flash ne4 kernel, root with towel root and reflash nf4 kernel
worked great for me

Hi all, I just dug up my old S3 and need to go back to stock. It has a CM11 nightly on there with the MK3 baseband and CWM recovery (and no Knox loaded!). Needless to say, I've been out of the loop for the past year or so and all of these threads about Odin and the newer updates have my head spinning! I want to go back to stock but also want the ability to re-root and load a different ROM later on. If I use the Odin one click here (http://forum.xda-developers.com/showthread.php?t=2755793), would this cause any problem with re-rooting, recovery, or whatever else? I was burned on my newer Droid MAXX when I updated to a firmware that couldn't be rooted so I don't want that to happen in this case if possible.
TL;DR
If I'm on Cyanogenmod with MK3 (no Knox bootloader), what's the safest way to go back to stock with the ability to re-root later?
Thanks!

But if I was to use the one-click, wouldn't that load Knox and that would be permanently disabling any downgrading in the future? If I just flashed the stock 4.3 ROM and installed as normal through CWM, that should keep everything the same (bootloader,modem,etc) correct?
Yes... 4.3 has Knox by the way.
I flashed the 4.3 ROM and haven't had any issues so far. Still managed to avoid installing Knox somehow. Download mode doesn't mention anything about a warranty bit.
