Hi, I'm really tired of all the custom software installed on my xplay that I don't use and would like to root my phone so I can get rid of it. My only fear is that I will have trouble updating to ICS once it is released.
I know I would be able to flash the ROM manually once it's posted here but I don't like relying on that, I'd prefer to do it the "official" way.
Is there a way to unroot your phone so you can use the vendor provided update method? If not, can someone explain to me the process of applying an official update to a rooted phone?
Thanks
Rooting the phone only adds a few files to the phone giving it root permissions.
I got my phone as 2.3.3 from rogers, rooted it. Then I updated it the official way to 2.3.4. It removed the root permissions, but it updated fine, then I just rooted it again.
You shouldn't have a problem.
And if all else fails, reflash back to the stock rom, then update.

Thanks! I'll give it a go
I had rooted my SGS3 while on 4.0.4 using the stock Samsung rom and Odin without issue no custom ROMS were installed just root access. Early August of 2013 the OTA for 4.1.2 was rolled out and I had accepted the update which was installed without issue, which apparently should not have been the case (everything I can find says OTAs will fail if you have root access, but this was not the case). I now want to either return to a full stock to get the 4.3.3 update at which point I may remain unrooted, or gain root again and update to 4.3.3 with root. I'm cautious about how to proceed here since I've read about a lot of people bricking their phones while attempting to root after 4.3.3. My primary concern is that my flash counter is tripped at 1, but I don't have root access and am not sure how to proceed with out potentially damaging my phone. So I'm essentially getting the worst of both worlds (unable to receive stock updates from carrier, no root access to update otherwise.) and don't want to be stuck on 4.1.2 for the life of this phone. I still have SuperSU installed, but when I open it it says "There is no SuperSU Binary installed and Super SU cannot install it. This is a problem!"
I have searched these forums and a few related to it, and from what I can gather I should just reroot the phone following instructions for 4.1.2, but if I want to make the jump to 4.3.3 I wasn't clear if this would be needed or not, but none of the threads I could find directly addressed the issue for the ATT SGS3 i747. The closest I found was a thread posted last month where the OP was directed to the CF Root procedures, but there was no followup after that. I'm just a little leery about what might happen if I reroot with another method and end up with duplicate files/.apks etc related to the root process on my phone.
I also wanted to be sure that rerooting using a different method wouldn't somehow damage my phone.
Can someone with some experience please advise of the safest best practice for me to either recover root and update, or remove root and update so I can start fresh later? From what I can gather this should be an easy fix, but I would prefer to rely on the expertise of someone more knowledgable as opposed to winging it on a gut feeling I will be ok.
So I rooted my phone using the method outlined in this thread here:
http://forum.xda-developers.com/showthread.php?t=1771687
I used odin to flash the 4.1.2 T-Mobile image and I stopped at the part that said "If you just want a stock, rooted phone with no custom recovery, no plans to flash custom roms, etc. then you can stop HERE" because I only wanted root so I could fix the keyboard bug (keyboard would revert to stock one after resets).
So my question is, can I update to 4.3 via the OTA update that is in the About Device > Software Update section in the phone? Looking elsewhere the official instructions say that the phone should not be rooted before updating. If so, can I get rid of the root in order to update? (As far as I know, the keyboard bug doesn't exist in 4.3 anyway so I don't think I need the root anymore). If not, how can I update to 4.3?
Lastly, and somewhat unrelated, can I use the factory data reset in the Back up and reset section of the settings? Previously in my experience with roms, this would lead to a boot loop but I'm not sure if that is the case with this so-called rooted stock rom.
Thanks in advance.
You can use OTA RootKeeper to temporarily disable Root so that you will receive the update. Or you could also visit the Root66 thread you have linked. There you will see Rooted version of the 4.3 update.
Having said that, You will want to Research the consequences of the 4.3 Stock update. In particular you wish to research the consequences of CIQ, KNOX and the new EFuse Bootloader.
I am by no means an expert but I figure I just did this so it may help you out. I updated my phone to 4.3 accidentally on purpose and then I decided to root my phone like the next day. I used Mr Robinson's method and then used his third method to download the ROM manager and install CWM Recovery and then I put Cyanogen on it. I have not had any issues except the app Trailer Addict doesn't work with it but that is not a big issue. I have everything else that I wanted and more. I don't care about the flash counter since I am not under warranty. Oh and you can use Titanium Backup to back up your apps. I didn't do this the first time so I had to back up from Kies 3 by dragging files onto my SD card and not all worked. I hope I helped a little.
RE: Downgrade Galaxy S3 I747 from 4.3(knox) to 4.1.2???
Hi guys,
I've been searching online and no luck finding a good answers. I have a Galaxy S3 I747M(Canadian) that was handed to me.... Sad part is, most average users, whenever they see an update for the phone, they freaking update without research the pros or cons.
Anyhows, I was fiddling with my Galaxy Note 2 and came across on how disable KNOX to achieve Rooting and I thought***** Light Bulb*
Here's my idea, not sure if this will work but, I will root my Galaxy S3 and use the same idea by disabling KNOX using Dr Ketan multitool to rename Knox.*apk files then inject busy box and root. (By the way, I have rooted my S3 this way and it achieve rooting no problem).
Now the question is, since KNOX is disabled, would I be able to downgrade to 4.1.2? Just wondering if other people out there has ever done this route by disabling KNOX and then do downgrade....
What do you guys think?

Dont do it. You will BRICK your phone. For the moment on android 4.3 Samsung galaxy i747M (same as mine on Rogers) therse no way to downgrade. Yon wont be able to downgrade anyway because you have the new bootloader and with the new one, you CANT downgrade, or if you try, you will Soft-Brick your phone.
(In the past, i got an HTC EVO 3D and Soft-Bricked my phone by flashing a wrong Kernel.... so i made some research on the web and i found the a JTAG may be able to unbrick my phone and flash back the good Kernel the good ROM and the good bootloader.... So I sent it to a store who was repairing smrtphones. Tey tell me that they knew what my problem is so they should be able ot fix it but... the next day when i came to get my HTC they told me that finnally EVEN with the JTAG they wasnt able to repair it...)
* All of that to tell you : dont trust JTAG sometimes it may not work...

I have the i747 canadian model too and althpugh you can't downgrade to stock 4.1.2, you can definetly flash a custom 4.1.2 rom which DOES NOT include a bootloader. Im currently running hyperdrive rls 16 which is 4.1.2 based and before that i was rooted on stock 4.3.

I have a question along the same lines, is it possible to restore a nandroid of 4.1.1 or 4.1.2 after updating the bootloader? Does restoring a nandroid affect the bootloader?
I actually haven't don't the official update yet, specifically because I don't like that it's one way. I flashed stock 4.3 without updating the bootloader and I like the improvements.

No by restauring your phone whit nandroid if you are on 4.3 with the new bootloader you will brick your device...
Code:
[ro.bootloader]: [I747MVLUEMK5]
[ro.build.id]: [JZO54K]
[ro.build.hidden_ver]: [I747MVLDMF1]
I'm able to get 4.1.* running but none of the modems seem to work.
Am I screwed if I need to network/sim unlock this?
EDIT: Just found out about EFSv1 vs. EFSv2. Looks like I'm boned for a free unlock.

You cannot use the free method to sim unlock the phone unless you are running a completely stock ROM, inclduing the bootloader. There were a couple of users that downgraded everything to 4.1.1 from 4.3 except the bootloader and the required unlock menu options were not available.
Because the 4.3 upgrade changes to format of the EFS partition.
Nope, its all because of the modem. You never had to flash a 4.1.1 rom, only the modem. The problem is that once you've updated to 4.3, older modems no longer function.
There is little more than factoryapp, s/n, and drm related data on the EFS partition of these devices. They are not like many others where a lot of NV data was stored there.
This is also why backing up the EFS, while not a bad idea, does not protect against many of the things people think it will, such as IMEI loss.
Hi, I need your help!
i have I747 AT&T with 4.1.1 PDA: I747UCDLK3
My main concern what will brick my device if i try downgrade from 4.3 coustm rom?!
Can anyone give my a full list of BT+MO+Ke ? what I found in XDA is short list.
4.3+ bootloader - YES! (I747UCUEMJB and Up will brick )
I being told that I747UCUEMJ2 is the higher i can get downgrade without porblems
I rellay don't know which Modems & Kernals are belong to 4.1.1 VS 4.3+
Modems - ? (will loss IMEI) can I use old modem like:I747UCDMG2/UCDLK3 on 4.3+ ?
Kernels - ?

Once on 4.3 or above you cannot flash older firmware. Only the modem belonging to each build will work.
You can flash older roms, but thats it.
I am looking to just get ROOT without any changes in the stock kernel.
I don't want the weird name sounding ROM's or any of that.
Just some way to get root so I can load Titanium Backup and FREEZE the AT&T bloatware
I just go the OTA today (11/14/14) when I turned my phone on. It's the AT&T SGH-I317
and now say
Android 4.4.2
Build Number
KOT49H.I317UCUCNJ1
Device Status
Official
So is there a quick and easy way to do this?
I use a iMac BUT I can boot into Windows 7 Ultimate also (which from rooting phones before I usually always go that route).
Any help/directions would be appreciated.
Also this, who comes up with those weird names for different ROM's that NEVER really explain, in plain old English, what they do?
I can't (or don't want to) learn the syntax lingo used to find a working ROM that does just a simple thing, give you ROOT, even after reboots/yank battery/etc.
Maybe a one-click solution?
thanks :fingers-crossed:

You should try CF Autoroot
any confirmation that CF root works on 4.4.2 with NJ1 OTA update/
as soon as someone gets a root to stick
and I mean just standard, stock adding su to the mix
post the steps as to how you did it
a one click root would of course be the best......
but at least tell us how you did it, and screen shots to show would help too.
thanks

I haven't gotten root with Odin yet. No brick in and everything shows custom but US throws an error
