Hey guys. I've been looking for this information online and I just haven't been able to get any help.
I hardbricked my s3(wont power on) while on 4.4.2, while trying to install a bootloader/modem. I cant even remember which one I installed, it was chaos trying to get cm 11 working.
Is there a unbrick img that works for the i747m model on 4.4.2? Is there any way to fix my phone without a jig or jtag or any DIY methods? I've read a unbrick threads and some say they don't have a fix for 4.4.2 yet but im not sure if they are just outdated.
Any help would be greatly appreciated

We need to know which one you flashed so we can suggest a fix. Otherwise, you could end up flashing the wrong bootloaders/baseband and hard-brick your phone (if it's not already).
As for the unbrick, it is for 4.3. I don't think we have one for 4.4.2 yet.
A Jig is only helpful if you didn't mess with the bootloaders.
If you've flashed the 4.4.2 modem on 4.3 firmware, there is no way to fix this type of brick yet. I think one or two other people who hard bricked differently on 4.4.2 have been able to fix theirs. Hard to remember for sure. (Everyone keeps opening new threads for every brick rather than just posting in the existing thread so it makes it a lot harder to keep track of what has worked, and even more difficult to find the relevant posts again.....)

I have Hard Bricked my SPH-L710 (noob mistake). I upgraded to 4.3 without reading up on features. Everybody now knows about the annoying KNOX security that comes with it but i did something so HORRIFIC lol i tried to downgrade. didnt end so well. little did i know trying to downgrade with KNOX causes a hard brick..:crying: everyones trying to do the SD card trick where you image the debrick image on the sd card. people are mad to find out that if you upgraded 4.3 you cant fix a hard brick that way anymore. UNLESS someone extracts the boot image from their rooted 4.3 SPH-L710 device then there is a chance that this method will work. use Philz recovery to root 4.3. and someone get this image for me!! dont just do it for me get it for other models too. be nice. or if there is, will someone link it to this thread. or any other way to fix this hard brick.
will a jig work ? i know how to fix it if i get to download mode.

i Bricked mines too, i have been looking for it too hopefully someone share's the file
Same here, bricked Boot Loader *sigh* Mine came from an idiotic move with the EZ-Unlock app tho. Suppose my next step is to invest in a Class 10 SD Card and pray for the best. There is some other threads around here that have various S3 unbrick images tho, just gotta poke around :good:
I'm in the same boat guys
Aggghh.....I pray for this file every night to fix both mine AND my hubby's GS3. Yup.....had so much confidence in myself (Really it was cockiness) that I bricked mine and then his!
me too...bah!
I missread the dev topic on the S3 Factory reset and counter and got burned. I was running a custom 4.3 and thought I was good...oh well.
I have tried the SD card method with several different images, but alas I am still in crapville without a shovel. $50 to send off for repairs or wait for something to come along. Right now I am hurting, hard to believe that phone was so important! Argh! Has anyone had luck?
Sigh...a little searching helps.

I rooted my old milestone many years ago but havee been keeping my devices stock ever since, until today that is. Today I decided I wanted to try to root my Samsung SGH-I747M with Telus and everything seemed to start off smoothly. Once installed the SuperSU stopped working. I tried fixs I had read online such as updating the app, but this did not work. I read on a forum that you could flash something to disable know to help fix the problem. When I tried going this avenue I was not able to reboot my phone. I tried restoring from a backup taken before flashing, but I havent done any of this in so long im not entirely sure the backup took properly. At one point I got a message saying no OS was installed but after restoring this seemed to go away. I apparently do not remember anything about rooting from my milestone and am hoping someone may be able to help me get out of this mess. I am currently downloading the stock firmware and I think I will try flashing it tomorrow. I also was hoping someone could point me in the direction of a thread on xda that went into a more detailed explanation of how rooting works, what specifically roms and flashing all is and does. Any help is greatly appreciated.

General section is most likely the best place for that.
Here's a How-to that should get you started: http://forum.xda-developers.com/showthread.php?t=2538991

The Only problem is I already attempted to follow this and my phone will no longer boot up. Also I tried navigating through the stickies. couldn't find much info for my device. I will be trying to flash the stock firmware tonight but I want to have a clear understanding on what flashing is and what the difference is between os firmware kernel and rom and such BEFORE flashing this firmware tonight. I hope someone will be able to help.

Well that info is already in the Sticky Index. Understanding what you're doing (or about to do) is really important but you gotta start reading, it's all there.
OS, firmware and ROM are the same thing.
When your phone boots, it basically goes: Bootloaders -> Kernel -> ROM (OS).
The kernel has pretty much all the "underground" controls (RAM, Mhz, governor, scheduler, BT, Wifi, etc).
I won't write everything but those are the basics.
Also, having a Canadian variant of the S3 (that's what the M is for), doesn't change much other than flashing bootloaders and stock ROM (which you'll wanna use the Canadian variant bootloaders and Telus ROM for stock). Everything else is basically the same.

Sweet I will definitely check that out. So I did flash twrp to my phone. Is it possible that I flashed the version say for the i747 but not the m version and that is why the phone wont move past the samsung screen? Also should I attempt to get rid of twrp before flashing the stock firmware. This should answer all my questions and then I will explore the stickies some more.

If flashing a stock ROM, flash the Telus one. If flashing a custom ROM, it doesn't matter (I747 or M variant), as long as it's D2LTE.
Your recovery doesn't change anything to flashing with Odin, it will overwrite it.
Flashing the stock firmware fixed my problems. Thanks for all of your help and I will definitely be checking out the links that you sent me before trying to root again tomorrow.
i can't seem to find much info on root/recovery for g3. i found a little bit about bump and stump.... saying that twrp is possible but not much hard reliable facts on the topic.
Can someone who knows what they are talking about or knows a link to someone who knows what they're talking about help me get informed?
Basically i just want to know the procedure, how reliable it is (what are the chances of bricking the device), and any other relevant info that may be available. Any help is greatly appreciated and i'll be looking forward to developing some themes for this phone .
Thanks,
KS
*edit* also wondering if anyone has tried backing up a rooted version of the stock rom and restoring it. Does this work? Or do you have to flash kdz to return to stock after trying out some custom roms?
follow this video... https://www.youtube.com/watch?v=j5T7By2Zqvk (you can skip the parts on installing the rom)
Here goes...
I got a new phone which is running great and before selling my S3, I wanted to install CM and get rid of the bloatware. Figured it would help the sale. Ha!
The S3 was already rooted and CWM installed but still using the stock OS. Here's where I really ****ed up, I didn't right down the baseband version or android version before trying to get CM installed.
CM10 wouldn't install so after some digging I read that I needed to unlock the bootloader. All the sites say to use EZ-unlock. I do. It unlocks. I restart the device and it's now hard bricked.
Before becoming a brick, I made a backup using CWM but I'm not sure how helpful it is at this point.
I don't know which Android version I'm running but it should be the latest OTA since I always installed the updates.
I tried debrick images for 4.3 and 4.4.2 without any luck.
Essentially, I need a little bit of guidance before I give up for good on this phone. How can I find out which Android version was running in order to use the right debrick img. Does it matter that I was using a custom recovery and that the phone was rooted?
Thanks for the help, guys. I've got too far down the rabbit hole and I'm trying to get out.
i live a little below the bottom of the rabbit hole. my first and only (so far , fingers crossed) brick was by trying to unlock the bootloader of my att i747 s3. guess what :banghead: they arent locked. go figure. and again :banghead: my best guess if you kept updates updated. search for whatever was the latest (which you should be on) use a debrick image for that version. and i guess youve already read the "debrick thread". if one microsd card doesnt work , try another. read too many times where one class/size would work for one user but not another.
i know this isnt much help. i would just say keep trying.
maybe even jtag might ¿ help?
good luck.
maybe try here if havent already.

thats what pretty much happend to me on my s3 i747M. i was downloading a custom rom, phone was rooted had its original os, but i installed a rom, that said it was for i747m, but it was really for the i9300. so after it seemed to install, i click reboot, and instant brick. i also made a WHOLE backup before i did anything, and have flashed a number of different roms in the past.

Not quite the same situation. I was following instructions install a new rom and it said to unlock the bootloader when in the end it wasn't necessary. EZ-unlock bricked my phone. I will keep trying with various SD cards.
Does anyone have a link to a KitKat (4.4.2) debrick dump for the I747?

A friend of mine brought his i747 to me to see if I can fix his phone because it was tripping out. I decided to root it and installed CM13. That however created even more trouble for the phone. It changed the device model to T999 and also the imei and baseband where unknown. I tried to return it to stock but I couldn't find any site that has the 4.1.1 or 4.1.2 and only found a link to 4.3. I decided to flash that with odin and the phone became unresponsive after that. Is there away in which I can find this or do I need to get a new mother board?
Where did you get the 4.3 file? Do you have the file name?

Do you get any vibrations when trying to power it on? Try to take it apart if you are comfortable and look for any physical damage if it doesn't show anything at all. Sometimes the board is damaged pretty bad but still boots, but restoring/flashing bootloader will completely brick it beyond recovery.
If it does give some response then you can look at the other unbrick threads and try em one by one. Wish you luck! BTW if all fails I have a s3 without a screen but good logicboard and stuff I can sell it to you. Or I could also buy the screen off you if you would like. Just PM me if that is the case. Anyways hope you can unbrick it.
