[Q] Galaxy S3 randomly restarted and got stuck at CWM boot screen. Is it bricked?

I have a Sprint GS3 with CWM 10.2.1 nightly that was installed
I was at work today when I noticed the phone restart and come back up to the boot screen, it stayed there for a good 5 minutes so I tried restarting it, same thing happened
I am able to get into download mode and CWM recovery mode
I put the phone in download mode and flashed the stock ROM via Odin. Odin showed PASS, but the phone had multiple errors in a wall of red text. Most were ERROR mounting
Now it boots into the Samsung logo and freezes there. Is there a way to fix this?

[Q] Help - There is something wrong with my Phone!

Hi XDA Forums,
I have a problem with my Note 2 for some reason.
Let me explain you what is wrong with my Note 2
I was sitting down and watching a movie, my phone was right next to me, The phone randomly turned off and after couple of second it had turned back on. It had showed the first every screen when you turn it on "Samsung Galaxy Note 2 N7100". Now from there it keeps on looping the same screen over and over again.
I had done some research before opening this thread, I saw that some people said I should try factory resetting it from the recovery mode, I then tried going on the recovery mode, it was not successful, it had showed me the same "Samsung Galaxy Note 2 N7100" screen and then repeated to boot loop it self again, I tried going on the recovery a couple of times but it didn't let me go on it.
Next I had then downloaded the 4.1.2 Official Firmware from SamMobile to flash it to stock again, I had then tried going on the Download Mode, It goes to the screen for Download Mode, but when I try pressing up to continue from the warning message it had then rebooted it itself and made it self stuck on the screen again.
Basically, my phone is stuck on boot loop, It does not let me access the recovery mode and it also does not let me access download mode.
ROM Using: Tigra_RomV3 4.3 Based ROM
Kernel Used: The Kernel which comes with the ROM or Stock, I didn't change the kernel myself.
If there is a internal problem does that mean I wont get help from the Warranty because the phone was rooted?

hello,
just try to use the jig, it should work...
use it so your phone will be in download mode, then flash your rom

Do you NANDROID backup? Maybe you may restore it by custom recovery.
Second, remove the battery first for a while and retry to access the RECOVERY and DOWNLOAD mode. If not, try the suggestion up there.

Not your Usual Boot Loop

Hi Guys hoping someone can help me out.
One of my friends who should know better decided to try and flash a custom rom to his N7105 trouble is he used a n7100 twrp which apparently installed and then tried to flash a n7100 rom .
Now his phone is stuck in a boot loop, it sometimes gets as far as the animated boot logo with the blue led pulsing depending on what I last did to it lol. I can get into both download and recovery and the power button isn't stuck.
I don't know what stock version the phone was one when he started messing with it and he is vague about everything HE tried to do to fix it before I got my hands on it. Its entirely possible it was on 4.1.2 to start off with and he's tried to go straight to lollipop does the 7105 need to update in increments? or could he have put a n7100 bootloader on somehow but flashing stock via Odin should fix that right?
I have a memory of people having this sort of problem years ago with HTC and it ended up being a mismatch between the modem and baseband versions or something like that, thoughts?
Here's what I've tried
Odin flash CF-Auto root as it restores stock recovery at least now the PC detects it as t0lte not t03g
1) Recovery wipe data and cache - now only gets as far as the initial samsung galaxy note II screen
2) Odin flashing a 4.1.2 rom from sammobile - no go "unsupported" so has a knox bootloader
3) Odin flashing a 4.3 rom from sammobile - hangs on animated boot logo with the blue led pulsing
tried 1 again same result
4) Odin flashing a 4.4.2 rom from sammobile - hangs on animated boot logo with the blue led pulsing
tried 1 again same result
5) Install firmware via Kies - hangs on animated boot logo with the blue led pulsing
tried 1 again same result
Odin Flash proper version of twrp 2.8.7.0
6)Fix permissions in TWRP - says sucessfull but also has "E: unable to mount data" etc back to the initial galaxy note II screen
7) Flash custom rom via twrp - hangs on animated boot logo with the blue led pulsing
tried 1 again same result
I'm running out of ideas and patience with this thing does anyone have any other ideas for me to try?

After leaving the phone for a while to prevent me from smashing it into a million bits with the biggest hammer I could find I got it working tonight.
Charged the phone up I had to disconnect and reconnect a few times as it said it was 100% on the full screen battery picture then in recovery it said 18% or something
I re-flashed N7105XXUFNL2_N7105H3GFOD1_H3G from sammobile using Odin 1.85 along with the PIT file from this thread checking re-partition (I used a pit file otherwise I'd leave this alone), Auto Reboot, F.Reset time and Phone Bootloader update. This seemed to take longer than previous flashes.
Flashed TWRP 2.8.7.0
formatted Data in TWRP (the advanced one where you have to type yes to confirm). Previously Data was unmountable so I assume the long flash fixed something there.
Wiped cache in TWRP
and rebooted and waited ages and it came to life
