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.
So my family is about to switch to AT&T from Boost Mobile. And I think I am getting a Galaxy S3 from them. And I would love to root and install CM in it. But I have been hearing reports of AT&T's locked bootloader policy and such. Should I worry about it for the S3? Or does it still have an unlocked bootloader? If it doesn't, should. I unlock it first, then root? Or root first? Please reply, and if you do, thanks,

if your phone firmware is higher then 4.1.2 then
check if your phone is locked or not Dial *#7465625# into your phone, a screen will pop up telling you what is on.
if Network lock is ON that mean your phone is locked and for now there is no way to unlock your phone for free (you have to pay for unlocking)
if your phone firmware version is 4.1.2 or lower then that then
go this link and find how to unlock your phone for free http://forum.xda-developers.com/showthread.php?t=2529200

The bootloader issues should not be insurmountable. Being a new phone I expect it will come with the 4.3 version of Jelly Bean installed. This will be the first thing to check once you have the phone. If it has 4.3, it will have Knox installed and this will need to be turned off to install a custom ROM. All I have seen regarding removing Knox is either after or at the same time you are rooting. To root, the CF-Auto-Root method works for many. Both the CF-Auto-Root and a second method are here This thread also links to a script which will remove Knox, if needed.
You will need to decide which version of CM you wish to install, probably 10.2 or 11. At this time the 4.3 bootloader will work with both. I would recommend reading about all of this, and having a fair understanding, before doing anything to your phone. I won't hurt to run it on stock for a week or two.
Some things to bear in mind: The phone may come with the 4.1.2 version of Jelly Bean, but I doubt it. If it does you will have to update the bootloader before proceeding, more reading because there is an option involved - the official 4.3 bootloader (MJB) or the leaked 4.3 bootloader (MJ2). There is a bit of a chance the phone could come with Android 4.4, KitKat. It all depends on the timing of when you get your phone, when AT&T rolls out the update, and if the store personnel update the phone giving that 4.4 is available. If it does come with 4.4, DO NOT change anything until those on here that do the good things for our phones understand how it behaves.
Remember all of the warnings about anything you do being your responsibility.
Hi!
I'm sorry if this has been asked before but I just can't find a definitive answer to this and I've been trying to search for an answer for nearly a week now.
My boss received a used Samsung Galaxy S3 from a friend of his in the states. It is a locked AT&T phone (SGH-I747) and it is on 4.3.
I managed to root the phone using CF-Auto-Root, which disabled Knox (whatever that is) and also installed CWM and was planning to flash 4.1.1 so I can unlock the phone using the *#NUM# method.
After reading a bit I've seen many people saying that you can't "downgrade" from 4.3 to anything else because it will brick your phone. Hence, I did not try and flash any other rom on the phone.
So I guess I'm just trying to get a definitive answer here because I can't find anything but rumors on this subject. I mean it's weird, I'd expect if you couldn't downgrade from 4.3 than it would be a bit more documented.
Has anybody tackled this problem with success?
Thank you
The normal method for the end user to conduct software updates and upgrades is via OTA or Kies. Using Kies or OTA doesn't require the end user to know about download mode, fastboot, or recovery mode. Samsung probably did not want non-technical users to brick their phones using download mode and Odin. It would be too easy for a non-techie to use the wrong firmware, tick the wrong options in Odin, etc.
I'm sure the fact that you cannot downgrade the bootloader has been well document by Samsung and its service centres. Based on the contents of my first paragraph, there would be no need for Samsung to advertise to the end user that the bootloader cannot be downgraded.

Right now there is no free way to unlock your phone if it's on 4.3.(you can downgrade to older stock android, but the 4.3 bootloader remains and messes up your phones IMEI until you go back to stock 4.3)
Anyhow, the reason you can't downgrade the bootloader is because there is no method discovered to do this yet. I ended up using gsmliberty to unlock, and they have a deal that you get a free unlock if you take a video when you unlock and upload it to vimeo/youtube using the format they request.
I did that and they re-funded me very quickly. So IMO this is the best "free" method until we can downgrade from 4.3 bootloader and do the 4.1.1 free unlock.
I was in the same situation, and I had to pay for an unlock code.
If you want to see me unlock it, here is the video: http://vimeo.com/96549806

What everyone else has said here is correct. You can't safely downgrade from 4.3 to free unlock - or free unlock by any other means for that matter once you are on 4.3. Your boss' friend would have unlocked prior to shipping the phone down but perhaps this was omitted. Your only options now would be to buy an unlock code online or perhaps the friend can contact AT&T to request the unlock code. If the device was off contract and is eligible for the unlock code, they would oblige the request. Otherwise, the code could cost between $18 - $30 online.
Thank you everybody.
I will use the service posted above.
I think it would be a good idea to make a sticky in this forum explaining that it is not possible at this point to downgrade from 4.3 (or is that just the boot loader).
Thanks again.

It is just the bootloader that cannot be downgraded, not the ROM.
Hi Friends,
I just got a T-Mobile Note 3, that came with Firmware: NB4 (Android 4.4.2).
Can anyone confirm that they were able to Root and then use Region Lock Away to SIM Unlock their phone to use on other Carriers? I would like to use mine on AT&T?
If not possible, what did you do? Can I downgrade via a Custom ROM and then use it? Does installing Custom Recoveries STILL trip the Knox counter? Is there any way around it?
Thank you so much for your quick help!

I was able to root with Chainfire's AutoRoot, and then I used his RegionLock Away app to unlock it as well, so yes, it does work. Just follow the instructions carefully.
The method I used tripped Knox, but I don't know if there may be another method now that doesn't trip it.

I don't know of any way to downgrade your firmware but towelroot came out the other day that should work with our phone that claims to not trip Knox. I believe it works on the NE6 (latest) firmware. As for Region Lock Away, check the website to see if it has compatibility issues with NE6.

Thank you for your responses guys, I *think* the Firmeware I have is "NB4"... does that sound like a valid release?
And Techngro, could you confirm that you have "NB4" or 4.4.2 and Region Lock Away still worked?
I have been on Sprint N3 for a while, with last ROM installed 6 months ago, just Stock Rooted, Odined. I assume there is still NO WAY to install custom ROMs and Recoveries without tripping Knox?

when I was on nb4 I was unable to use region lock away and have it carrier unlock. things may have changed, but you will have to trip Knox if you want a root method for nb4. towelroot works on ne6 without tripping Knox, but again BBB unsure if region lock away has compatibility issues.

I guess, the most important thing to me is getting that SIM unlocked since I want to use it on the ATT network.
The Knox trip seems inevitable to me as well, since I really want to enjoy my Note 3 with all the ROMs and Themes out there, Sammy won't honor my warranty anyway, since I bought my phone from Craigslist...
So can anyone confirm or negate, if getting the SIM unlock via NB4 is possible? If so, how did they exactly do it?
If not, and I have Custom Recovery installed, can I just jump to ANY older ROM and basically get the Region Lock to work?
Thanks again!
Once on the 4.4 bootloader, you cannot roll back. You can definitely just use cf autoroot, and try out region lock away. It will trip Knox, but if inevitable, might as well take the plunge now and give it a try.
Or, upgrade firmware to ne6, use towel root, try region lock away. This way you keep Knox in tact and can report back.
But why do you need region away? Is the phone not paid off? If it is, just get unlock code from t-mobile. Mine only took 2 days.

Thanks for the very helpful advice there, bud.
Let me see if I understand these correctly:
1. No way to NOT trip Knox on NB4 and Root
2. To root without Knox I have to take a Firmware update to NE4 then do TowelRoot
3. Even if I have the Knox 0x0, there is NO WAY on the T-Mobile Note 3 to install and use Custom ROMs, Recoveries, Themes, and/or Kernels, correct? Because I thought ATT allowed that via Safe Strap?
I bought my Tmo N3 from Craigslist, probably never gonna have anyone honor a warranty on it - Sammy or Tmo. I am not a Tmo customer and wanna use the Tmo N3 on an ATT Prepaid MVNO, like Straight Talk.
That's why I need the Region Lock Away or SIM Unlock to work...

correct. if you came from jb to nb4 release, then you could've retained root through a work around method without tripping Knox.
but... since you are already on nb4 with Knox 0x0, there is no root method that doesn't trip it.
also correct that you can upgrade firmware through ne6 and use towel root without tripping Knox.
lastly, if your phone is paid off though, whether you have service or not through t mobile, they can provide you with the unlock code, because the phone is in fact paid for. unless it is not, then I can see the reason for region lock away.

What exactly do you mean by getting an unlock code from tmobile?? For about the past month I've been in Arkansas and i swear all they have is [email protected] towers and Verizon. I'm basically using my edge network the whole time which doesn't suffice. Is this unlock code something that let's you pick up off the other towers or would I need to go another route?!

This whole thread is about SIM unlocking the T-Mobile note 3 to use on another carriers network. The T-mobile note 3 is able to pretty much use any GSM carriers sim card (i.e. AT&T, Straight Talk, AIO/Cricket Wireless...) if you receive your unlock code: either through t-mobile themselves (by having a paid off phone), by using the region lock away by @Chainfire (may not work on all firmwares), or purchasing an unlock code from one of the websites that offer sim card unlocking. Once unlocked you can get one of the pre-paid sims (like AIO or Straight talk) for $10 and use AT&T towers, or just completely switch carriers.
This is in no way shape or form speaking about using root on these phones with an unlocked bootloader, which seems to confuse most people. I know you didn't ask this, just wanted to put it out there for anyone else who may be confused.
Okay that makes sense, thanks man!

I don't think you can root the att tab s. It has a locked bootloader
^^^^ Just like he said, AT&T does indeed lock their bootloaders. If they arent ecrypted there may be a way around it but thats not something I have any knowledge in as ive never owned a AT&T device.

I find this a bit suspicious because 1) No one else has root for it, and 2) SRS Root is not represented on XDA. I'm a bit hesitant to try it. Anyone feeling adventurous to try it and report back?

Seems new? I think I seen one like this but idk if this is the same. Well... Since it's based off of exploits by the looks of it, its best to do some more research on it. I might give it a try later idk since it saids supported for the T800 also
I would try it but I have not rooted in awhile and would hate to brick my tablet.

I have looked at it. It use adb and tries bunches of exploit. Since I'm already root I cannot try it. It would most likely not brick your tablet and its worth a try I guess. Up to you!
For anyone wanting to know if SRS Root works, it doesn't. After it connects through ADB, it tries many different exploits before applying the 4th one. Then is prompts that the device is successfully rooted and SuperUser has been installed. It then reboots the device just as CF Autoroot does, but it fails to actually root. This is my 1st device with a locked bootlader, so I'm considering swapping it for the T-Mobile version. Can't deal with the bloatware much longer

Both the T707 (AT&T Tab S 8.4) and T807 (AT&T Tab S 10.5) are rootable, as far as I know. The thing is, it depends on firmware. If you're using NH6 or NJ5, I think you can root. If you're running the latest NK1 firmware, you're out of luck for now.
