ok I'm not new to rooting and roming I'm coming off a rooted and Romed atrix 4g. My question is I was going to root my att s3 with the s3 root tool kit http://forum.xda-developers.com/showthread.php?t=1746665 which allows you to root and flash a custom recovery. but what I didn't see is a way to unlock the bootloader. I didn't know if that would be required, to flash a custom rom, I know I had to do that with my atrix. If so does anyone have any easy link for unlocking the bootloader. also I had heard that some people have had issues after root connecting to att lte. I wouldn't think it would matter since the apn's wouldn't change. thanks ahead of time for any help, and call me a noob if you want, I could care less.
Don't use that as I believe it will trip your flash counter.
Use the no trip root guide located in the android development section.
Also, you do not have to unlock the bootloader, it is already unlocked, you just have to get rooted by flashing with Odin and then install a recovery. I recommend TWRP which can be easily installed through goo manager once you are rooted.
The issues with LTE are not associated with rooting, but rather with flashing AOSP based ROMs but I do believe they have fixed most or all of those issues.
Lastly, I too cane from an Atrix and the S3 is a bazillion times better. I reccommend Triune 2 for a custom ICS ROM (avoid touchwiz JB ROMs for now) and Task650's AOKP ROM. Also, ktoonsez has the best kernel available with up to a 2.1GHz oc.
Cheers, PM me fellow atrix user if you need any other assistance.

yea i saw the other method too. maybe I'll go that way. i wasn't to worried about the whole tripping the flash counter. since it looks like chainfire has a fix. although it sounded like that could be more risky than rooting. thanks for the answer about the bootloader and the lte issues. actually still on the atrix for the moment running nuetrino bc the first night i had the s3 i dropped it and completely cracked the screen. was a little disappointed since i have dropped my atrix countless times and never had an issue. oh well thanks for in store warranties.
Yeah, I've seen some people have had issues using the Triangle Away app, so it's better to just not trip the counter to begin with.

It has been 16 days since I have my Galaxy S3 and has not felt the need to Root yet. before I had the Evo 4g, Samsung Galaxy S2 and after 2 or 3 days playing with them went and root it them. with this one I have not felt the need of rooting yet. reason?, maybe the Stock rom provides all I need or want. I particularly like the notification bar and all the options it offer. also the limited customization of the lock screen. also the option of battery persentage. but, who can stop the urge to root?. lately I saw the battery improvement on a thread and the better reception by flashing a radio(LF9). so my urge to root and flash is back. what do you guys think?.
I have had mine since the 7th and I have yet to root. I came from an epic and had that thing rooted after a few days of having it. I just haven't had the need to do it yet. This phone is solid and has all the little things in the stock set up that I would always flashed to have.

Perhaps finaly Phone companies has figure out that if they give us more candy we won't root. just a thouth.
I'd do it for tethering alone
If you think the stock Rom looks good and you don't want aosp, or any other tweaks rooting can provide, then don't root.
If you do root and don't like it you have the option to go back to stock and even un-root. You can even stay on stock Rom but have root. All up to you.
I like the stock ROM mostly, but I rooted within days just to get Titanium Backup Pro working. Like others have already posted - I had an Epic 4G before this, and quickly switched off of the stock ROM to various custom rolled ones before CM9 was available.

I rooted only to remove bloat with Titanium Backup and to easily restore all my apps from my Evo 3D. Also, as new updates come out, it may eventually be harder to obtain root. Figured it's easy, so I may as well now. As development picks up I'm sure I'll be flashing new stuff sooner or later.
I'm running the stock rom, infact after the last update I didn't even reinstall CWM. But I did root the phone as soon as I came home from the store. There are just too many things you can't do without root. The biggest for me is Adfree, but MyBackup, SDMaid, and a bunch others need root to fully function.
Yeah, I'd chime in and say at least root now and leave it stock until you find something you like better or don't like on your current setup.
Root
I came from the Infuse 4G on ATT. It was rooted running CM ICS. I have had this for 10 days a d not rooted yet. I would but with no computer I don't have any way right now as far as I have read yet. But I do like most everything and would only root right now for TiBu.

I only have linux boxes (and I'm too lazy to find a windows box), but I managed to root my sprint SGS3 today via the same method as the TF300 with one minor change:
I just made the symlink to /dev/block/mmcblk0p14 instead.
Code:
ln -s /dev/block/mmcblk0p14 tmp

Sorry, I guess you probably still can't do that without a computer. You have to run as the 'shell' user, and I don't know of a way to do that other than adb.
Yes
I told myself I would not root until the 2 wks. return were up
Didn't make it a day. Not being rooted is like buying a car and having a governor on the throttle. I might not want to go fast but I want the option.
Well,,,,, I did it..... could not resist the temptation of rooting. after 17 days on stock wich I was happy I rooted just a few moments ago. now in the process of trying my first custom rom. downloading now Strongsteve Odexed Blue. and from there many,many,many more to come. Happy Rooting!!!!! :laugh:
Hey Guys,
I used the galaxy nexus root kit to unlock my bootloader and to root my phone (I didn't install a custom rom, I just used what was default on the program after backing up my phone)
Here are my questions:
1) will I receive the official OTA upgrade / be able to install it?
2) If I am able to will that re-lock the bootloader on my phone?
I'm pretty hesitant to install any custom rom of Jellybean since I've had problems with them in the past almost leading up to a bricked phone, so I just wanted to make sure that the OTA will come to my phone, and that it'll work after I being installing it.
Thanks!
~Mike
If I remember right, if you don't have a custom recovery installed, you should still be able to get the OTA.
hmmm well I know that there is clockworksmod on here, but nothing else. I know thats a recovery program... I wonder if I should just flash the google asop direct from google for my verizon nexus :\
My understanding of the matter is that once you are rooted with a custom recovery, you should steer clear of OTA updates. They can definitely break root and have the potential to hard brick the device. This information is from my experiences with an Evo, so things may be different with the Nexus. I've only had mine for a month or so and haven't done enough reading yet to say for certain. If you really want the OTA there is a one-click method to return to stock over in the development section. Haven't been in that thread yet, so I don't know what kind of success/failure rate it's getting. Just read the last couple of pages and you should have a pretty fair idea of how it's going. If it seems doubtful, there are also several excellent guides for doing it manually. efrant has a link to one in his sig I think. Hope this helps!

The OTA won't auto-install if you have CWM recovery flashed. You can use CWM to flash the update manually, but it will never work automatically.
Phone was lost, just got replacement this morning.
My last S4 had been rooted running custom firmware for months w/o issue.
Read through a bunch of threads, ranging from the opinion that the bootloader change + knox wont be a big issue to the sky is falling.
Is it recommended to root my phone at this time, I do have JUMP and would be replacing it once something better comes out? The phone is running 4.2.2, caught it trying to update to already.
Thanks.. I know this may seem redundant but haven't been active on these boards since I got my CFW going. Not seeking help in flashing or anything.. just advice

Up to you. If the stock rom is bearable and you wanna run the 4.3 stock rom then by all means, go for it.

Being that your'e using the T-Mobile M919, the whole KNOX bootloader situation doesn't pertain to you as long as you're sure you're on 4.2.2. Root it, flash it, theme it with Hello Kitty... whatever, it doesn't matter; you can still revert back to stock and reset any tripped counters. 4.3 is when the problems begin and the KNOX counter is implemented and can't be reset.

I second this.
SO LONG AS YOU ARE ON 4.2.2
- You can root flash do whatever, theme with hello kitty or barbie xD like lordcheeto said or keep it stock
- Install recovery and flash away.
- Will always be able to revert back to 100 percent stock
TAKE 4.3 UPDATE
- I think you are still able to root it without tripping knox counter. Can't remember the last status of that was. But as long as you root it without a custom recovery, i think you are ok. From what i can remember, the bootloader checks the recovery status and trips the knox counter based off the recovery that is on the device. If its different then stock, it trips. But double check with Google about this first.
- If you trip knox counter, you will NEVER (as of now and possibly forever) get it back to zero.
Rooting with safe root won't trip knox and also disables it. But recoveries, kernels, roms, etc will trip the flag

Root it with chain fire and never look back.
You're on 4.22, so you're golden. Just flash a rooted stock ROM that's on 4.3 and you'll avoid Knox.
I'm running 4.4.2 and never seen this Knox stuff.

Correct. I've rooted my my second GS4G on 4.3 MK2 and it did not trip the KNOX counter. If you're still on 4.2.2 MDL, then there is no need to update your bootloader. Simply flash ROMs through recovery and flash the 4.3 modem. You will have the goodness of 4.3 on KNOX-less 4.2.2 bootloader. :highfive:
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'll get this out of the way first, I'm pretty new to rooting and flashing ROMs. The only thing I've ever rooted before was a free Kindle Fire I got from Amazon, and got some version of Android on it a looong time ago. Now I want to get LiquidSmooth on my Galaxy S3 i747. I'm completely willing to follow all noob guides by myself namely http://forum.xda-developers.com/showthread.php?t=1802160]this one.
HOWEVER, since this is a phone from AT&T with a data plan, texting, and calling, and not some free Kindle with none of that, I'm extremely paranoid to do anything risking losing all these features. There's really no clear indication anywhere that this will or won't happen, since I assume this is either just extremely common knowledge, and most trouble shooting is about screwing up in general or bricking.
Rooting and flashing doesn't affect any if those things.
Think of it as a new operating system for your computer. New look, new feel same basic functions.

I have the same phone and there are a few things that are good to know that will help you and possibly keep you from making a bad choice.
Have you accepted the 4.3 OTA update from AT&T on the unit or...? If you have, then you have upgraded to a specific bootloader/modem and can no longer downgrade those items without causing problems.

If you did not take the update then you dont have these new items and your options are more open i guess.
First, your going to need to root your phone, without tripping the flash counter. There are lots of guides on how to do this, and it's pretty simple.
Secondly you will need to install a custom recovery such as ClockWorkMod or TWRP. I used CWM on my i747 and installed it using "ROM Manager" from the Play Store. It was amazingly simple and did the entire process for me.
Third you will need to choose the ROM you would like to try. There are a few different kinds, so happy hunting. I chose S3Rx and I love it. It's packed full of goodies and it seems that the Dev seems pretty good at answering any posts on his thread in this forum about the ROM.
Before you do any of that, you should verify what version your are running right now so you know what bootloader/modem you have, then go from there.
I just got back into this stuff myself and I love this phone. Good luck.
