[Q] galaxy s3 I747 wont boot past Samsung Galaxy s3 Logo, Did i brick my phone???

I was trying to carrier unlock my phone, and to do that i tried to downgrade it 4.3 to 4.1.1, and only after i had pressed the button, i had noticed that this might brick my phone in a comment in one of the forums, this is what i did:
http://forum.xda-developers.com/showthread.php?t=2625461
after following this and trying to run odin with it, odin returned "FAIL", and due to my high level of stupidity at the time, i tried to use the original 4.1.1 as my PDA in odin right after, i didnt reboot or anything, just pressed start again with the other tar.md5 file....
so now i cannot go past the samsung galaxy s3 logo when booting. I CAN go into download mode though, but i have no clue what i am supposed to do afterwards
i have the Galaxy S 3 i747 (was 4.3 before the whole mess) at&t carrier, i am trying to unlock it because i am travelling and need a phone.
please help me fix it, i do not care about the warranty since i dont have it anymore anyways, as long as the phone is working
also, if possible, i also need to unlock it afterwards, any help is HIGHLY appreciated, thanks!

Downgrading your boot loader from 4.3 is a guaranteed brick. I'm not sure if the brick will get you to the Samsung screen.
If you're already assuming its bricked reboot into recovery and do a full wipe. Restore a nandroid of something if you have one or try flashing a custom ROM. Because Odin failed maybe it never flashed the boot loader.

Welcome to the forum! Wished you'd come in much earlier though as you would have found you CANNOT downgrade from 4.3 to 4.1.1 to free unlock. Sorry, but once you are on 4.3, the surest way to unlock is to obtain the unlock code from the carrier or purchase one online. Sounds like you do have a soft brick. If your phone is still booting to the Samsung logo, then it's only a soft brick. Attempting to downgrade the 4.3 bootloader usually results in a hard brick so you may be in luck.
To fix this first, try to see if you can boot to recovery mode and do a hard wipe/factory reset. If you are able to boot to recovery (or download) mode then you have little to worry about. If the reset does not work, you can flash custom recovery via Odin and follow the instructions in the thread below to restore stock 4.3. Afraid, you have to revert to full stock 4.3 to get the phone back in working order and don't even think about 4.1.1.

If you are not able to get to recovery, then you can see if you can boot from a debrick image following the instructions (on the first page) of the thread below ...
http://forum.xda-developers.com/showthread.php?t=2549068
Once your phone is working normally, you can request the unlock code from AT&T via the request form below. If eligible, they should provide this. Otherwise, you would have to buy one online ....

I am able to get to recovery, but the first link isn't very clear.... i am not really familiar with odin and all this other stuff... lol, i am now downloading the files it says to download in the first link though, can you maybe tell me in a quick list what exactly im supposed to do?
thanks!

It's time to start reading. Before doing any flashing/modding, you should make sure you understand what you're doing and know the risks.
Now as for Odin, it's quite straight forward. Phone needs to be in download mode, you put the PDA file in Odin and flash (if it's a Odin one-click, just need to hit start). One thing is to not interrupt it! Especially if flashing bootloaders cause that will brick your phone. Also, don't downgrade bootloaders.
There are a few guides in the sticky, I suggest you take an hour or two reading them so things like that don't happen again (or that you know what to do if it does).
GL!

Alright. If wipe/reset didn't work, you'll need to restore full stock 4.3 via custom recovery. Here's what we need to do....
1) Download the Odin flashable *.Tar file for custom recovery. I prefer TWRP because of the GUI so that's where I'm pointing you to ...
http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.6.3.1-d2att.tar
2) Download the stock restore file for 4.3 from the thread below... If you are using TWRP, then the first link is the one you need
http://forum.xda-developers.com/showthread.php?t=2658486
3) Copy the stock restore zip file to a good quality (micro) SD card
4) I presume you have Odin already so you will use this to flash custom recovery to your phone. Run Odin.exe on your PC. If you are using Odin v.3.09 then you need the AP tab. For all other versions, use the PDA tab. Navigate to the custom recovery *.Tar file you downloaded earlier and place this in the PDA (or AP tab). Leave the default settings as is and do not check/uncheck any boxes other than the default settings.
5) Boot the phone to download mode via the 3-button combo (Volume Down/Home/Power). When you get to Odin (Download) mode, press volume up to continue. Connect the phone to your PC with a good quality micro USB cable. Wait until Odin has recognized the device then click on the Start button to start firmware installation (flashing). Wait for the flashing to end and the <Pass> message. Disconnect the phone from the PC and pull the battery to stop auto reboot.
6) Place the micro SD card with the stock restore zip in your phone. Replace the battery and boot to recovery mode. If you were successful with the firmware flashing above, it should boot you to custom recovery.
7) Select install from external card and navigate to the stock restore zip file. Select this file and swipe the screen to start firmware installation. Wait for installation to complete. Then clear your cache/dalvik and reboot to system.
This will hopefully do it.

[Q] Help! Fix Stuck on Boot Logo

Hello there, all xda members.
I got Ace 2 to fix from my friend. He doesnt know exactly why did the phone becoming stuck on bootlogo. Maybe messing up with flashing GB or JB. or maybe wrong terminal command.
Ace 2 Condition :
- Its unable to pass boot logo samsung galaxy ace 2
- Its unable to enter recovery mode
- Its able to enter download mode, and its custom binary download : No, Current binary : Samsung official
Here all the thing that i have tried to fix the phone :
1. Flashing the phone with Russian Gingerbread with 3 files, Pit, CSC, and PDA. But it still stuck on bootlogo and unable to enter stock recovery. it shows succeed though on Odin, but it can't boot.
2. Flashing the phone with Latest Jelly bean, with Jelly bean pit file. Odin displaying succeed, but it doesnt boot either.
Can someone help me how to solve this problem?
Is there a condition where phone completely unable to recover from hardbrick such as stuck on bootlogo, but still able to enter download mode?
I'm going to download jelly bean mb2 or mb4 which include pit and csc from jelly bean and try to reflash it. Hope it gonna work.
Thanks for any help.

Anyone here to help me?
@ChronoMonochrome , maybe you've experienced something like this and able to resolve the problem.
The phone can't boot at all. and im a little frustrated here. I've already tried a 3 parted firmware MB4, and it doesnt work either. Tried to flash chrono 4.3 cwm through odin and it doesnt work either.
And if it really doesnt have a solution, maybe i'll just give it up. And doesnt continue researching to fix this phone. Thanks
maybe another devs that able to fix this. @ace2nutzer @fluffi444 or anyone??
It got the same case. Successfull flashing, but still doesnt boot, it just like flashing is fail. or it just like it reverted the way it was before flashing. Your help is very appreciated.

Very strange. And more strange is that several people have this "only boot to logo / only downloadmode issue"
Up to now I have no Idea - I asume that ADB is not working, because of missing recovery mode? With ADB there are plenty of possibilities.
An complete Factory reset could be helpfull - But how to do it out of downloadmode ?! Don't know.
Up to now I didn't had a Phone with this behaviour for repair at home. If it would be reproducible how this all happens, I would bring my phone to this state to find out how to repair it (riff box here - so dead ACE 2 is not a problem) - But even this is unclear - Every report regarding this said only "suddenly" "without any reason" "flashed this or that" - But no exact infomation what happend acctually.
I'm out of Ideas. Sorry!

Thanks for answering.
I dont know if i have to give up already or not. But i'll try to flash it with another pc and data cable. Maybe it gonna work.

No, I haven't had the phone in such condition as described above. But I have heard that any odin-flashable file that's wrongly flashed via "Phone" entry can lead brick which is similar to this. I remember only one case - one user from 4pda has flashed some file via odin, wrongly putting file to the "phone", and wasn't able to restore it anyhow - but he also had some brick on GPIO side - vol.up worked like vol.down, and the real vol.down didn't work at all. I don't know however, what memory partitions / any devices capable of storing data would be messed after this operation, and whether it's reparable at all. I mentioned devices, that can also store data, I know only that touchscreen has small memory for its firmware(that what I had broke one day in the past after accidental firmware change in the kernel) - but maybe some other devices also has it?!
There are also some chances that it's dead flash memory - chances are pretty small, but should also be taken into account.

(issue resolved) note 8.0 stuck on opening screen

I have a Note 8.0 that is stuck in a boot loop. It get to the initial screen. "Samsung Galaxy Note 8.0 GT-N5110" and then screen goes blank and it starts over again. Never goes past this screen. I have flashed a stock rom (\N5110UEU2COI3_N5110XAR2COI3_HOME.tar.md5) using odin. Odin gives me a pass when it is finished but the issue persists.
Any help with this is appreciated.

Re-flash the stock ROM but, before booting for the first time, boot into stock recovery and do a full wipe. This may help get out of the bootloop.

audit13, thanks for the suggestion. I tried 3 times with no success. I did see the android with his belly door opened and the blue box spinning. Didn't see that before. However when I boot into recovery the android's belly door has a red triangle in it. A full wipe/reset has no effect and the symptoms persist.
Any other thoughts? Thanks again

I recommend trying again with Odin 3.07.
In Odin, uncheck everything except f.reset time. Connect the tablet in download mode, flash the tar.md5 file in PDA. When you see the word "Reset" in the status window, remove USB cable, press and hold the power button to power off the unit. After the unit is off, use the key combination to boot immediately into recovery and perform a factory wipe/reset. If that doesn't work, you may need to flash the ROM in combination with a pit file.

audit13, tried your instructions and still ended up with the same issue. I used odin3 v3.07. Can you point me to the pit file you referred to in your previous post.
I have this file - BL_N5110UEU2CNE2_1498778_REV01_user_low_ship.tar.md5
and this - CSC_XAR_N5110XAR2CNE2_1498778_REV01_user_low_ship.tar.md5
Are they of any use to me in this situation?
Thanks again for taking an interest in my problem, Keith

Did you download the stock ROM from sammobile? If you did, you should unzip the file once which gives you a tar.md5 file. It is this tar.md5 that is flashed in the PDA section of Odin 3.07.

SamMobile has many countries listed but not USA. Do I use Cellular South? The file I have been trying was not from SamMobile.

When you boot into download mode, does it give you the model #? Do you see anything about Knox or warranty bit in download mode?
The firmware named in the original post looks like it matches Cellular South.
I'm not sure if the 5110 was sold in the USA. If your model is wifi only, another country may work. If it's celluar, different countries use different frequencies which means cross flashing may work but connectivity (wifi and cellular) may not work.

Download mode shows this:
Odin mode (in red)
Product name: GT-N5110
Current binary: Samsung Official
System status: Custom
Knox Warranty Void: 0
RP SWREV: A2

It's strange that you were able to flash a stock ROM but the system status is "custom".
I suggest trying to flash an entire ROM from sammobile.com similar to the BL and CSC you flashed earlier. It may be simplet to install a custom recovery and flash a custom ROM so you can at least confirm the baseband and bootloader currently installed.

I'll give a custom recovery and rom a try tonight after work. TWRP and any stable build correct?
As for those two separate files, I didn't try anything with them. I downloaded them in case I needed to use them.
This is a board that I got off eBay for $5 and I don't know it's history. Could this issue be hardware related? The board looks good with no signs of corrosion (water damage) of hot spots (electrical surge).
It seems as though it can't find the os on boot.
Thanks again.

Did the board ever boot or was it stuck in a bootloop from the beginning? How did you know which bootloader to flash?

The board has never booted. The only files I have flashed are the one in my first post and the one from SamMobile (Cellular South) as per your instructions. These two files appear to be one in the same. Both files when flashed produced the same result, boot loop.
Do the files contain a boot loader? It sure feels like that is where the problem lies.

Success! Flashed TWRP and then installed SlimKat 4.4.4 and all is working. Need to get gapps installed but for now this board is good.
audit13, thanks again for you interest in my issue.

NEED HELP! GT-I9190 Hard bricked, currently stuck in a bootloop

Hello! this is my first thread on this forum, which im making because I ran out of options, and don't know what to do...
It looked like my Galaxy S4 mini (GT-I9190) died last weekend (april 29) I was watching a video on youtube and suddendly it ''ran out of memory'' (the screen froze) and it turned completely black, the audio was still playing and I decided to force it to shut down (holding the power buttom)
The audio stopped, and I tried to boot it back but it wouldn't answer at all, so I removed the battery, put it back on, still nothing after many attempts (also trying download mode and recovery mode, none of them worked).
So I decided to plug it into the computer, and that's how I found it wasn't ''completely dead''
My computer detected the device as ''QHSUSB_DLOAD'' which was a good sign, meaning I wouldn't have to put my s4 mini to sleep forever.
So after some research, coming across people using 300 kohm resistors to force a bricked phone to dl mode, people using weird hardwares, Jtags and whatnot (all of these methods involved extra hardware) I found this:
http://forum.xda-developers.com/showthread.php?t=2625628 and this http://forum.xda-developers.com/showthread.php?t=2660566
The .img in the scard method, links up there.
So I gave it a try and guess what, it actually worked, my phone actually responded after placing back the sdcard and the battery, I didn't even had to press the power buttom.
My phone booted, but displaying this screen:
Boot recovery mode
Check boot partitions
Copy from T-Flash
Boot recovery. .
Write 139008 sectors. .
Flash write failure

after this point, It wouldn't go further
I tried download mode at least 10 times, I't didn't work, the phone booted back to that screen again.
So I switched the vol- for vol+ to see what happen (I was doing download mode: power vol- and home)
And It worked, my phone went to the ''Galaxy S4 mini GT-I9190'' Screen, the first screen you see when it actually boots.
but after this point, It bootlooped turning off and back on to this screen and so.
when the phone turned off, I tried download mode once again and IT FINALLY WORKED.
At this point I believed that everything was over, I would connect it into odin a flash a stock firmware.
But it just started... (here comes the interesting part)
I tried to flash a stock firmware with odin, yeah, the blue progress bar and everything, my phone rebooted, but nothing, the same bootloop again. Here comes an important question: Do I need to flash a specific region firmware? or any region should work? First, I flashed an argentina region firmware (ARO was the code), results: Bootloop
After that, I tried the Russian firmware (I dont know if the region of my phone is Rusia, but I believe so because after doing a factory reset, the default language was russian, please answer this as well) and BOOTLOOP again...
So basically, The main problem is a bootloop, but I dont know what is causing this
After this point, I'm stuck, and not knowing what to try...
I'm looking for answers, what should I do? what can I try?
If you can answer any of these questions please do it...
Do I need a specific region firmware? (I already tried argentina(ARO), and Rusia (SR)) oh yeah, I tried Rusia SR, should I try XE? XE seems to be a multi-region format (?) I don't have a clue actually... I really need the opinion of someone who knows about this
If the default language when doing a factory reset is russian, this means my phone's region is Rusia?
Is there a way to know the region of my phone, when hard bricked? I dont have the box, manuals, nothing...
What was that weird screen my phoned displayed after booting with the .img sdcard? (read the quotes higher in this post)
Is there a posibility that the bootloader is corrupted, and is causing the bootloop?
I want to try everything before a JTAG service, what are these hardwares? What do they do?
Oh here is an important question:
I read that the baseband of unbrick.img has to match the baseband of my phone... is this completely true? if so, what can I do? where can I get a specific baseband .img file, and what can I do since I already used another .img (I dont know if the baseband was the same) and im already stuck on a bootloop? If a use a correct baseband .img file will the phone stop the bootloop?
Im looking forward to see your posts...
If you need any aditional information feel free to ask...
If you don't have a clue, just like me, please send this thread link to someone who could help...
Thanks in advance!
EDIT: Also recovery mode NOT working, when trying to enter this mode, the galaxy s4 mini gti9190 screen displays ''entering recovery mode'' on the upper left screen, and after that it turns off and the bootloop continues

Still with the same problem and i cannot flash any Recovery like CWM or TWRP, cuz it does Pit File partition table error

Try a NAND-Erase, I dont suggest it but it could fix your problem. Goodluck

SM-G925F Stuck at factory reset, unable to enter the recovery mode and flash firmware

Hello and sorry if this is the wrong category...
It's my first time making a thread on xda.
I've been looking for an answer for the past 2 hours, but I still have a bricked phone... As the title says, I can't enter the recovery mode anymore. I tried to do a factory reset (when I could enter the recovery mode) and the phone got stuck at erasing. Now I can't enter the recovery mode anymore. I downloaded a new firmware from sammobile for the SM-G925F. The firmware works since I used it on an other phone and everything worked just fine. The problem is, when I open Odin and add the .tar file to AP, it gets stuck at nand write and sometimes on boot.img. The phone isn't showing that it's downloading anything (it has no progress bar). At this point I have no idea what to do...
Some extra info that could be helpful:
The phone was bootlooping when I got to fix it;
I work in a kind of phone repair store where customers bring their phones for hardware and software repair. I do the software;
I've installed new firmwares on multiple phones and I never had something like this... Normally some time with google and xda could help me to find a working way to fix the problem, but as I said... I've been looking for 2 hours and the problem is still here;
I'm not a pro with Android and phones. I just like to learn new things and I'm still learning.
Could it be a hardware problem?

Can you show me your phone's download mode image to see where could be the problem?
Also, make sure you are flashing latest firmware, if you are downgrading it - than you will get such boot errors.

*Update*
I found out what was wrong. The eMMC chip was broken.
