Here's a tricky problem, need expertise!! Kind of urgent..

[epicphotoeye]

I have read and read and read. I have "bricked" my phone in the past and fixed it. I have used, tested, and flashed many roms from this site (Thanks to all cooks for their work!) but I still consider myself somewhat 'new' to troubleshooting.

I woke up this morning to make some important phone calls today and as luck would have it, my phone was stalled again. It's been doing that for a few weeks now. My last flash was Open Touch 5.0 UL I believe (either that or 5.2 biggy) and it has been working great except for the occasional freeze.

EDIT: Forgot to add, the actual problem is now it won't boot up after it froze this morning. Just sits at the boot screen
So I've tried my other methods of fixing it... /edit

Except this morning nothing is working. I have tried flashing with Orig. T-mobile ruu, tried SD flashing with the RUU_signed.nbh, tried restarting the computer, phone, removing battery and sim... NOTHING! When trying the sd flash (which I've never done before today, it reads and tells me to push the down button but then goes to bootloader screen and just sits there. With the RUU I'm getting err 300 but I'm using the SAME RUU (4.10...) that I've used in the past to reflash my phone AND tried the new one (4.26...)

Possible problem: Does it matter what kind of usb cable you use? I don't have the normal one I use as I am not home but I figured usb is usb...

I've read about it being a motherboard issue, how common is this?

I've read somethings about MTTY, would this apply to me??

Please help, anyone who has any suggestion, I'll try it!!

Stats:

IPL 4.10.0002
SPL 4.10.0000

Wing w/ Open Touch Project 5.0 or 5.2

[epicphotoeye]

I appretiate it, that I did not know... I could barely find anything on how to do it even.

im having the same problem bt instead of freezing da screen jus goes different colors or jus goes gray and stays der

[epicphotoeye]

Thats basically what mine did. The colors would get messed up and no matter what button i pressed it would not do anything. My advice to you edrift, is BACK UP YOUR STUFF NOW and reflash it asap if you can still reboot. I can get into my phone at all now.

yea i tink i might jus throw my phone away.dis is jus gettin rediculous
