PLEASE Help! Stuck on Startup screen after Odin

Hello all
I was updating my gf phone from rooted UVALJ4 or UVALH2 (Cant remember now, but it was an old Firmware) to root66 T999_UVUENC2 via Odin 3.09 on my Win 7 pc but after the odin install (which passed) I rebooted the phone and I got stuck on the Samsung logo on the start up screen. After about 10 mins I pulled the battery and tried to enter the Recovery mode, but nothing appears. Just a black screen.
So i Odin flashed the TWRP 2.6.3.1 to try to get to a recovery, but that didnt work. Still no Recovery.
I then used odin to flash the stock tmobile UVUENC2 4.3 firmware and it still gets stuck on the Samsung screen.
Next I tried to unbrick it via http://forum.xda-developers.com/showthread.php?t=2439367 using "SGH-T999 4.3 only Debrick Image" and reflashed the stock 4.3 rom, but that didnt work. :crying:
What can I try next? WHat should I do? I can still access download mode, thats about it.
Please help if you can.
Thx
I dont know how but I got the stock recovery to finally appear and now I get these errors (see Pic) what do these mean?
The recovery errors read: E:failed to mount /data ( Invalid argument) can't mount "/data" (invalid argument)
E: Can't mount /data/log/recovery_log.txt
again thx

Never Mind Used Unified Android Toolkit to fix recovery and flash stock rom.
Thank god for that toolkit.
...time to donate
:victory:
Mod Please delete Thread.
Thx
In the future, try a factory reset, almost all boot hangs are solved with this. Happens because of incompatible data between versions, which would make sense condidering the jump you made. Kind of makes sense with the error message too, but I'm not 100% certain there.
Be careful with the toolkit. There is no support for it and it has bricked phones in the past.

Have you tried flashing a stock rom, with and without a pit file?

Stock recovery wont wipe / Boot Loop / Cache wont Wipe (invalid argument)

I have a S4 Mini that I am not sure if it is classified as BRICKED as I Have access to basic features .
Just to start I have no idea what percentage the phone battery is on, It is in a bootloop and stock recovery . when turned off and plugged in the battery system appears but doesn't not fully load.
I am trying to get a custom recovery on the phone but failing miserably . ADB sideload transfers the file CMW / TWRP but after reboot the phones recovery is still stock .
I have also tried ODIN with same error.
Inside stock recovery, I receive constant errors (invalid argument) wiping cache ect.
only thing I have not tried is loading a rom ? this maybe an idea. does anybody know or heard of a fix for this ? thanks

If you haven't figured this out yet I'll throw in my 2 cents.
Start here: http://forum.xda-developers.com/showthread.php?t=2678420
I don't know exactly what heimdall is but odin should work just fine for this. Try a few different odin versions if you have to as it has changed a lot over the years since the release of this phone.
Also make sure to uncheck reboot from odin, unplug after reflash, pull battery, then manually go to recovery immediately after flashing. If you get anywhere besides the TWRP you have to flash again.

A strange things i have notified on this phone......... every time i put the phone in download mode and using odin and at every flash i complete in theory i can see the flash count increase right ? In this phone after this all test and tryed i do i can see the flash count blocked at zero like i never flashing nothings....... it's normal ?
