[Q] Stuff is harder to find for sgh i747m

Hi im new on this forum and I would like to have some tricks and tips cause I just rooted my phone yesterday and it seems more difficult to find information for my phone I have a galaxy s3 on 4.3 sgh i747m with Rogers .... Is it me or there is just a lot more stuff made for the i9300... I have tried to find ROM'S and tricks to put CWM recovery but it's harder to find information !!
to put CWM recovery I saw a lot of stuff saying download rom manager and install CWM recovery with this app but they offer me a version of CWM recovery for a galaxy s3 (metro cps) they doesn't say if it's made for a sgh i747 so im really scared to do something wrong if I install this version of CWM recovery ..
Could some one help me maybe with website limks or a guide for beginers noob like me or this forum seem's to be really good with some people with knowledge
Before my galaxy s3 I had a Jailbreak Iphone 3gs a year ago but Rooting an Android and putting stuff on it is not really the same thing it's far away from it!

And does it matter if put some stuff on my phone made for at&t sprint etc.... even if those are sgh i747

Hey,
I am running CM11 d2att and CWM d2att on my i747m and it works perfectly. It has been so long since I did it that I can't remember the exact steps that I took, so I would do some more research. Everything I needed to know was on these forums somewhere.
I believe the rough steps I took were:
- Root
- Install CWM (d2att)
- Update bootloaders (i747m)
- Flash d2att rom
But I can't remember exactly, so do some research before you go ahead!

You can install pretty much whatever you'll find in these forums except for bootloaders and modems.
There are specific bootloaders/modem for the i747m vs. i747.
The rest, unless explicitely specified otherwise, is 100% compatible between i747 and i747m.
As for your recovery script, I would suggest installing TWRP instead of CWM.
TWRP is more user friendly for people that are new to Android and both are usually supported.
For this, go to the Play Store, download and install the "Goo manager" application.
Once installed, open up the app, hit the menu button and select the "install recovery script" option.
It will automatically select/download/install the correct recovery for your phone and ask you to confirm before doing so.

I recommend not updating your phone to any stock 4.3 ROM. A stock 4.3 ROM will install a 4.3 bootloader which cannot be downgraded and may cause problems when trying to root or get back to stock.
Some newer ROMs require an updated bootloader in order to install and boot. I am running a 4.1.2 bootloader on my i747m and don't have any problems installing 4.4.2 ROMs.
Rooting gives you access to the system files and does not unlock you bootloader.
For installing custom ROMs, I use Philz Touch which is based on CWM. I have tried TWRP and I was getting errors when flashing custom ROMs. I was able to flash the same ROM using Philz Touch without a problem. TWRP is more user friendly but doesn't work as well for me.

what do you mean when you say I recommend not updating your phone to any stock 4.3 ROM (when a custom rom is based on 4.3?) and can you explain me the bootloader thing in details how can I fix that or how can I unlock it ?

Your post says youhave 4.3 on your phone. Is it a stock 4.3 ROM?
d2att (i747) is the AT&T version of the s3. Canada has the i747m.
The bootloader does not need to be unlocked in order to install a custom recovery or to root like Motorola phones.
The bootloader is software that an OS works with in order to function as a phone.

yes its the 4.3 jelly bean stock rom
but can I put any custom rom for my model the i747 or 747m ? The carrier doesn't have any importance ?

Any warranty left on your phone? Installing a custom ROM will void your warranty.
If you want to install a custom rom, copy the ROM you want to the internal or external SD card, install Philz Touch recovery, boot into recovery, wipe cache, Dalvik, install the ROM, and reboot.
You can install any ROM for the d2att as long as the ROM supports the phone's bootloader.

How I know which bootloader I got? If I have the 4.3 jelly bean I have a 4.3 boot loader?

Since you have TWRP installed, you not flash custom ROMs. Look around for a ROM you like, download it to your phone's SD card, boot into recovery, wipe cache, Dalvik, flash ROM, reboot.

He meant you CAN flash custom roms.
As long as the rom isn't packaged with a modem or bootloader you can flash any AT&T rom as you please.

Are you on stock Rogers 4.3? If you are, loading a custom recovery will void the warranty by tripping the Knox counter.
If you have no warranty and just want to install a custom ROM, you can install a custom recovery via Odin and flash the ROM you want.

I prefer Philz Touch which is based on CWM because I had problems flashing with TWRP.
There should be no problem as long as the ROM is supported by TWRP.

You shouldn't just go around flashing all the ROMs you think look or sound cool. I would suggest doing your research beforehand. For example, if you want to install the newer KitKat ROMs, you HAVE to be on a JellyBean bootloader. Click HERE for the bootloader guide if you need it.
Also, your TWRP should always be up to date. The link for the latest (may be outdated, idk...)TWRP is HERE
Lastly, if you ever run into any problems and want to go back to stock, or you just want to start fresh and start from scratch, then use this. This has never failed on me. Click HERE
Remember, YMMV.
Best of luck!

I don't think you need a 4.3 bootloader for all ROMs. I have loaded Cyanfox, CM11, and Vidalus which are all 4.4.2 ROMs without issue. I personally prefer to stay away from the 4.3 bootloader because I want the ability to return my phone to stock for warranty purposes.
The OP is running 4.3 stock and the link you provided could brick his phone.

I never said that the OP needed to update his bootloader, I was just mentioning as an example if he wanted to then he would probably need to if he wanted to flash a KitKat ROM.
But you are right, for him, I would stay away from 4.3 since you can't downgrade.

[Q] downgrading to cyanogenmod 10.2

hey guys,
i recently rooted my galaxy s3 i747 and installed cm11 on it. the whole process was done automatically using one of those cm installers. however, i recently learned that cm11 is not stable yet. so i want to downgrade to 10.2 which is the most recent stable cm.
i did try that, using manual methods, such as flashing it via recovery, however a picture of a dead android with a red warning triangle popped up saying it couldn't be done.
my question is, why would this happen? i know official android doesn't allow downgrade, but rooted ones should allow installation of any custom rom no matter which verison, right?
another question, how do i downgrade to 10.2, or install any other stable custom rom? i am afraid that the phone might become bricked due to my inexperience, but i want stability in my phone.
also, if my phone is indeed hard bricked, would it be possible to get it fixed under $100?
P.S. i am quite new to xda, so sorry if i posted this in the wrong area.

Are you using the most up to date custom recovery for your phone? Are you wiping system, Dalvik, and cache before installting the new ROM?

used goo manager to install recovery, and wiped system, dalvik cache and cache. you see, i was following a video tutorial, and the custom recovery on that one was an older version. so, although i wiped them all, it was a bit different. you think that might be the problem?

I would start over by flashing the tar version of Philz Touch via Odin 3.07 from here: http://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2att.
Copy CM10.2 to your phone or external SD card, boot into recovery, wipe cache, Dalvik, data, and system. Then install CM10.2, boot into the OS, set things up, boot into recovery, and flash Gapps.
I prefer doing everything via recovery mode.

thanks! aah i'm a little scared though. do you think if i follow the instructions correctly, there'll be little chance of a hard brick? i know nothing's full proof tho.... what do you think? is it worth it? is 10.2 better than cm11 nightly as of yet?

You're using an AT&T s3 i747? What ROM was on the phone before you installed a custom ROM?
If it was any stock 4.3, don't touch the bootloader.

yup s3 i747 with bell. i think its the same as att. the phone came with 4.2 then i updated to 4.3 jelly bean.

The model # for the Bell s3 is i747m. The AT&T version is an i747. Make note of the difference when posting and looking solutions.
Do you have any warranty left on your phone? If you do, installing the 4.3 update will install the 4.3 bootloader and Knox. Once you have upgraded to the 4.3 bootloader, any attempts to downgrade the bootloader will brick the phone. Any reason you updated to 4.3?
Since you have Knox on your phone, installing a custom recovery will trip the knox counter and void your warranty. If you have no warranty left, tripping the counter isn't a problem.

hmm when i look at my about phone it just says SMASUNG-SGH-I747... so i'm not sure where i747m comes in... i assume there's no warranty for my phone anymore since it's been rooted already. i just updated to 4.3 because i assumed that a reputable company like samsung would give out a good and better performance update. after i updated however, the phone started going haywire. it became laggy and slow. not that noticable, but still bothered me. the main reason i ditched iphone was because of it's sluggy behavior. so i had nothing to do but root. cm11's great, but some features are unstable, like random reboots and stuff. so i wanted to try cm10.2 or miui v5. hmm. i'm still thinking about how to figure out odin..

The Bell, Rogers, and Telus version of the s3 is sgh-i747m. The AT&T version is sgh-i747. Did you get the phone from one of the Canadian carriers?
If you're running a custom ROM, this may be the reason it just shows sgh-i747. Custom ROMs on XDA are designed for the d2att but are compatible with the Canadian version of the s3.
Updating to 4.3 would have loaded a 4.3 bootloader and Knox. Once your phone has the 4.3 bootloader, do not attempt to downgrade the bootloader as it will brick your phone.
Knox software can interfere when trying to root your device.
You updated to 4.3, then installed CM?

ah i understand now. i got the phone from bell. thanks for clarifying that.
i installed cm after the update, unfortunately. but when i went into recovery mode, i did not see anything related to knox. does it show up on the phone or in recovery mode? as of this moment, i was not thinking about the bootloader. because we're just tyring to downgrade the os, right? or is it something like previous os would not run on an updated bootloader?

[Q] AOKP KitKat SIM Unlock Clarification

Ok, I've read like 14 threads on this, but can't seem to verify an answer for my specific set up. So, sorry if this seems obvious to you guys. I def don't want to brick my phone.
I'm on AOKP Task650 4.4.3 (kitkat) ROM. Obviously the stock 4.1.1 SIM unlock method won't work on AOKP and I've read that the 4.3 version isn't able to downgrade and flash to a 4.1.1 ROM. What about 4.4.3? I also read that has to do with the bootloader and something about bootloaders with Knox on them won't work. I don't think that's my case.
When I go into my bootloader, I see:
ODIN MODE
Product Name: SGH-I747
Custom Binary Download: Yes (1 counts)
Current Binary: Custom
System Status: Custom
Qualcomm secureboot: Enable
So does that mean I can downgrade to 4.1.1 and unlock or am I SOL when it comes to unlocking?
Second part...if I can downgrade, do I have to do it via ODIN, or can I simply flask a ROM zip via TWRP?
If I have to do it via ODIN, can I perform a backup, flash 4.1.1, unlock, then go back into TWRP and restore to my 4.4.3 KitKat ROM?

Oki believe that's 4.1.1 so you can flash a 4.1.1 ROM and unlock....(I'm not a 100% so someone check me on that please)

Downgrading to the stock 4.1.1 ROM will erase all data so make sure you backup everything before using Odin to go back to stock.
Based on the information from the download screen and your baseband, you should be fine to downgrade.

[SOLVED] [Q] Rogers i747M Cyanogenmod 11 back to Telus stock ROM 4.3

I got Rogers Samsung Galaxy S3 SGH-I747M.
On it is installed Cyanogenmod 11 20140531 nighty d2lte with Android 4.4.2.
I found this firmware : Canada (Rogers) (Black Edition) , 2012 May , I747MVLALE8
PDA: I747MVLALH1 CSC: I747MOYBALH1 MODEM: I747MVLLH1
and program Odin3-v3.09.
The phone is locked to Rogers.
The color is white.
My goal is to unlock SIM lock.
1. Can I put firmware in zip format on SD card and just restore from SD card in recovery mode?
2. If no, what steps to do to reach the goal to get 4.1.1 stock ROM (rogers? telus? att?) to unlock SIM lock?
3. Maybe I have to do it from laptop with Odin or from the phone with Odin?
4. What are my options to get the goal 4.1.1. stock to get unlock SIM lock because I found free solution with that requirements on XDA forum?

Is there any 4.4.x custom rom for samsung gt-s6312
Sent from my GT-S6312 using XDA Free mobile app

What bootloader is on your phone? If you have the stock 4.3 bootloader, you will have to purchase an unlock code.
Boot into download and look at the text on the screen. Do you see anything about warranty bit?

You have the 4.3 bootloader which can't be downgraded; therefore, you will have to buy an unlock code.

Thank you for reply!
Than more I know than more questions:
a) The ROM I found here is stock ROM 4.3 I can revert to -? -> by meanhacker -> Rogers (RWC) MK5 , because I checked about baseband version is i747mvluemk5.
b) I bought the code and when inserted non-accepted active SIM card from my another carrier, got the window asking PIN to unlock network , entered and got unsuccessful. The company said is right unlock code by IMEI sure.
So my question is does the particular Cyanogenmod 11-20140531-nighty-d2lte custom firmware prevent somehow to unlock SIM lock?
c) Do I have this KNOX issue or not, or is it prevent to downgrade ?
d) I found some KNOX remover can I apply it and downgrade after?

You should revert to a stock 4.3 ROM in order to use the unlock code.
There is a 4.3 ROM for Rogers you can use . search for a pre_rooted ROM on xda.

And that one has no knox issues and after flashing I can downgrade?
For the purpose to enter unlock code can I use only stock ROM from Rogers or I can flash any 4.3 ROM like from Bell, Telus, or , even ATT?

You cannot downgrade your bootloader.
Do not load any ROM via Odin that is older than 4.3. Don't load any att ROM as that could brick your phone too.
Was your phone ever running stock kit kat?

ANDROID 4.4.2 that is a state i got the phone. past is unknown for me.
now i put zip noknox rooted telus file ROM_I747MVLUEKM5_STOCK_ROOTED_TELUS_NO-KNOX
on sd card
after went to recovery mode and did wipe,reset,dalvik wipe and choosed the file to install
got error installation aborted (status 7)

I don't have KK on my i747m. I loaded the stock 4.1.2 ROM and went straight to a custom 4.4 ROM.
Did you ever have the stock 4.4 ROM on your phone? If you did, I'm not sure if you can load a stock Rogers 4.3 ROM via Odin because the stock 4.4 ROM may have altered the 4.3 bootloader. The stock Rogers 4.3 ROM from sammobile.com and the pre-rooted ROM on XDA will load a stock 4.3 bootloader if flashed via Odin. You could flash a stock ROM via mobile Odin which does not alter the bootloader.
Once you are on the 4.3 bootloader, you cannot downgrade the bootloader regardless of whether you do or do not have Knox.
If you are sure you never had the stock 4.4 ROM on your phone, you could use Odin to load a stock Rogers 4.3 ROM, unlock your phone, go back to a custom ROM.
When flashing a ROM or altering your phone's software, there is always the risk of bricking your phone. Just be prepared to deal with a possible brick.

How I can check version of boot loader installed on my device?
How can I check version of modem installed in my device?
Can I use Google ADK tools (adb and fast boot) instead Heimdall (Odin is not compatible with my MacBook).

What is the baseband on your phone under About?

I747MVLUEKM5
But I solved problem to revert back to stock ROM using file I747MVLUEMK5_I747MOYBEMK5_TLS
been installing not from SD card but using laptop and Odin.
After I boot the phone I put SIM card and on pop-upped window entered official unlock code.
For using Odin program, I downloaded from internet vmware fusion, after found my cd disk with windows 7 ultimate and installed it.
After installed Odin and transferred above file to internal system and put the phone in downloaded mode connected and after a few minutes I get my phone booted with stock ROM.
What I surprised I did not find official page in Wiki of Cyanogenmod for official way to uninstall their product.
So I decided not to install the software that does not have official uninstallation tool. They have installation program only.
It's not good for us regular users. Before to come into the dark room usually it has to have to see exit way clearly.

I know of no custom ROM that can completely uninstall itself. One of best ways to revert back to stock is to flash via Odin which you were able to do.
Once I got the upgrade bug, I don't stick with stock for too long.
Congratulations on your success:good:
