[Q] Can't get Galaxy S3 (Tmobile) to boot

So after rooting my recent Tmobile GS3 and then attempting to flash the overclock my phone simply wont turn on. The root did fine, and I was able to install setcpu and everything but the second I installed the overclock my phone shut down. Now whenever I attempt to turn my phone it just flashes the Samsung insignia and then it shuts down. I can get to the Downloading screen (by pressing Volume down + power + home) but can I do anything about that? If someone can help me out that would be amazing. Thanks.
Also, I tried flashing a stock rom with Odin and it keeps failing. If anyone knows anything thank you.

Can you get into recovery? Volume up + home + power
If so then flash back to a nandroid backup or to a new rom or whatever.
If recovery wont boot, try again but look for blue text at the top right corner that says "booting recovery" when the sammy logo comes up. I've had it where my recovery wouldnt boot but I saw that for a split second when I tried. If this is the case, get back into download mode and flash the insecure boot + cwm again with Odin. Then you should be able to get into recovery.
If Odin fails to flash, reboot you're computer and try a different USB cable.

If you can get to download mode, then you're probably in good shape.
There are a few tricks that can be found in this thread:

Just make sure when you odin/flash something, you are flashing the correct image for your phone/carrier.

same boat here
well I thought I'd give it a try using instructions here. and now I'm hosed. I was able to root and install the ALLINONE (Insecure Boot, CWM & Busybox) rebooted, super user showed up in apps etc. I thought everything was fine. the next thing I tried was disable boot up animation and now the phone won't boot up at all.
I can get into the recovery and download screens but whenever I try to restore I get "can't mount /sdcard/"
The toolkit no longer sees my phone either. When it's plugged in and the toolkit is active, it just cycles over and over "samsung" then "Samsung Galaxy SIII" logo then black screen repeat.
The toolkit keeps giving message either "device not found" or "Waiting for USB debugging to be enabled".
download mode/ Odin mode is working- I have downloaded the file:
Samsung-Updates.com-SGH-T999_TMB_1_20120523140229_ogindgck8z.zip
but haven't been able to get Odin to load it ... I have to be in download mode for that to work right?
Any tips are appreciated.

Try flashing the same file you did to get root with Odin... then you should at least be able to get in to recovery and from there you're golden.

I tried that a few times to no avail and gave up. figured out that I needed to unzip the stock rom from t-mobile in order for Odin to recognize and load it. That's where I left it last night. So I'm now back to stock and reloading all my apps and settings.
I'm ok with that, this is my first go at flashing/rooting. My phone works ... and for that I'm breathing a little easier. thanks for your reply!

Next lesson I need to study is the full backup so I don't have to re-do everything (took about 1.5 hours) -- the hardest one was my tasker macros.

yep. That was the first thing I did after rooting. everything is nicely backed up to the internal SD as well as dropbox. Thanks! Looking forward to some really slick ROMs.

Another yellow triangle, can I fix this brick? Verizon Nexus

I have been reading the other threads about similar situation both on here and on galaxynexusforums but I think my situation may be slightly different, if not terribly worse.
I has been running my Verizon Galaxy with BAMF 1.25 and was going to upgrade to 2.4 or whatever is the newest. I was doing it all through CWM recovery, I deleted DATA, and Cache, THEN and where Im pretty sure I screwed the pooch was though CWM recovery I also formatted Data, Cache and SDcard
At that point when I rebooted I got the red triangle with the little android being worked on, I was still able to get in to recovery and fastboot and Download mode, but it would not boot past any of that. My assumption is that I deleted the whole OS and since I formatted everything there wasn't even a backup or any rom to install. Everything was gone. My computer also no longer recognized it as a phone/mobile device or even as storage. I re-installed the all the Samsung drivers and still nothing. My phone is not seen by the galaxy nexus tool kit, odin, or kies
At this point I attempted to go to stock via Odin, to mysid-icl53f-factory-65895fa8. This failed, I got the big red box in Odin and was going to pull the battery as the Odin faq says and do it again, but then the phone booted in to the dreaded yellow triangle exclamation point. This is all my phone does. I can not boot back into recovery, or download or any other possible alternate.
So this is where I am at, booting to the phone/pda..yellow triangle..computer screen and can go no further and my phone is not seen as a functional device on my PC even after installing driers again.
I do have one of those dongles that force the phone to boot to download mode coming from ebay. but without any OS at all (or so it seems) I dont know if it will do anything. I do have insurance on it so I'm not that worried on it, but I would rather not have to pay the deductible and be shamed for my success at bricking what is supposed to be unbrickable.
any ideas?

I am not very experienced, but can you get into boot menu? (Just volume up + down + power) if so, you might be able to install galaxy nexus toolbox on PC, install drivers from there, download factory IMG on PC and install IMG through the toolbox via usb.. or reflash cwm through the toolbox and recover nandroid if you have it

No, I can't get to any other menu. Power + Vol up or Power + Vol Down or Power + Vol up AND down. Don't do anything. I really think I may have completely formatted the phone to nothing or close too it. I was able to get a new one though warranty however so that should be here in a few days.

I did, try it before I got the yellow triangle and it didnt work. Now I can't in to download mode, and the odin program wont recognize the phone, either do to it not being able to get in to the download mode or because despite reinstalling all samsung drivers, my computer wont recognize the device as anything.

If you can get into fastboot mode, I am assuming the bootloader, then you can use the gnex toolbox and reflash the factory image and start over.

No, like I said no combination of button presses will put the phone into any other mode.

Could have used fast boot to push a ROM to the device, then enter recovery and flash the ROM.

Need PIT file for this phone (I think)... URGENT REQUEST

All of this to get the stupid Google Wallet working. So pissed off right now.
Anyway tried to reflash my phone I seem to have screwed up the partition I think because it hangs on the Samsung logo. Tried to reboot into stock recovery and it doesn't do it (instead it keeps rebooting).
Trying to reflash the partition info, but for that I think I need a PIT file. Anyone know where I can get that??? I have been Googling the hell out of it and can't find it.

Yes.... I have flashed the stock ROM 4 to 5 times. It flashes successfully, reboots, and sticks on the Samsung Logo screen. Tried to reboot into recovery, and as long as I am holding the 3 buttons for recovery, it goes into a boot loop (like it tries to go to recovery, it isn't there, and reboots).

For recovery
- Power Down + Home + Power
- Release Power at first sign of SAMSUNG Logo EXCEPT Power Down + Home
- Release Power Down + Down at first blink of Samsung
- Once in recovery, factory reset, format option
- Reboot, wait for 1-2 mins

did you also try clearing the cache? i've had a few hangs on the samsung logo, clearing the cache helped it get through

I feel so stupid. I didn't release power while trying to get into recovery. Although I have another problem now, and the searches online don't look good.
My Baseband and IMEI is showing as "Unknown"... Also the phone is very laggy.
EDIT
On this thread I started out by saying that I think I clicked Re-partition, but I actually think I accidentally clicked Nand Erase All... I can get to download mode and recovery mode, but my phone shows Baseband and IMEI of unknown. Any help?

More information:
When going to stock recovery I see a few instances of:
Failed to mount /data (Invalid Argument).
EDIT -
When booting phone I have no internal memory (16Gig).

that happened to me once when clicking a random box in odin without knowing what it did on my epic touch...thank god i work for sprint and was able to just order my own replacement sounds like you wiped your IMEI, and thats a ***** to inject back in...youll need to the help of a true dev to restore, but your best bet is to hard brick and claim warranty, friend.

Of course this would happen today, where warranty replacement will take 2 days to get to me.
I already installed and ran (barely) Triangle Away, and got the counter reset so I am good there for warranty. I am begging the community for two things.
If someone knows a "true dev" that may be able to help me, I would sincerely ask that you point them to this thread and see what they can do. I will be monitoring this thread VERY CLOSELY until I say otherwise (in this thread).
Can someone point me in a direction to hard brick my phone???

here is the pit and when you go into recovery you have to factory reset or it stays bricked http://db.tt/gKSxQKWJ
go into odin and place the stock rom in pda then place the pit on the top where it says pit and make sure to click repartition.then when done take the battery out boot into recovery then factory reset and it should work.

Does using odin to flash the stock firmware restore baseband? Or flashing a moden? Also did you ever make a backup that included your efs folder? If you did restore that backup:thumbup:

[Q] Black Screen - Won't Boot

Was using the Galaxy S3 toolkit to update cwm, went to flash an AOSP rom intended for d2att models, went to reboot the device... It flashes the samsung logo briefly then sits at a black screen with a solid amber LED. ODIN does not see it, my PC sees the device but I can't flash anything at all. Can't get to download mode either holding the power and any combination of the volume keys does nothing. Someone please help point me in the right direction to fix this. Thanks in advance.

If or PC sees it u could check and see if ADB sees it and maybe wipe and flash from there

If it takes longer than 10 or so minutes, pull the battery, replace and booting into stock recovery. Wipe data and cache. Reboot

It take bit longer than normal but it should boot within a minute or two

I plug the USB cable and pull the battery out, put it back in and unplug the USB...
So i need to replace my power button so i can boot to recovery/download mode?

If it's stuck in a boot loop, yes. I can't think of any other way I'm afraid.

If you want download mode, you could try a USB jig.

I thought about that, but didn't suggest because he will almost certainly still have boot problems until he can boot recovery and factory reset.
Worth a try if a jig is handy, but if you have to order or make one it'll probably just add more time to getting it fixed.

Edit: I flashed the StockROM back to my S3 and for any reason it is in Stock recovery mode. How do i get out of there w/o my power button? My computer don't recognize my phone so ADB won't work :3 (

Battery pull I guess is probably the only way. If you're running completely stock, you'll probably need to flash an insecure kernel for ADB to work in recovery.
This may be of use to you though....If you use the KT747 4.4.2 kernel, when you plug it in it will turn on the device if it's already off. You have to be on a stock based 4.4.2 rom to use it though.
I know it doesn't address your current issue, but thought I'd mention it in case something like that was useful for now.

If i pull the battery and wait(did it like 2h) and install it back, it reboots in recovery though

You can't flash anything from stock recovery. You'd need to install TWRP. Are you rooted?
How did you flash the stock rom?
You really need to get odin working though. Uninstall kies. Try different USB drivers, different cables, ports....
