mytouch 4g wont come on

I had freezing issues, my mytouch 4g would just end a call and i'd have to take out the battery and restart it or it would freeze on a screen, even the start screen and wouldn't do anything and i'd have to take out the battery and restart it. I tried deleting apps to make it stop doing this but nothing was working. I talked on my phone the other night and as soon as i hung up it froze, i tried restarting it and now all it will do is go to the mytouch 4g boot screen, but it wont boot up. usually it would flash that screen and go to the screen with the green dot the wrote my in the center then reboot, but it wont go past the mytouch 4g screen.
I have tried holding the volume down button and set back to factory settings, but all that did was sit on the skateboarding androids screen until the battey died, I have tried this many times both with and without my sim and SD cards in.
I have tried recovery and my phone acts like its going to restart then flashes a phone with a red triangle and exclamation point on it and wont do anything, wont even come back on until i take the battery out and put it back in and turn it on again.
I'm at a loss as what to do so any help would be greatly appreciated. thank you in advance for helping me... I miss my phone!!!!

im having the same problem.

the last time this happened i called tmobile and the hard reset worked..but now its not even working. now, when it starts up(once in a while) it loads..but when i go to slide the screen to unlock, it just shows me the mytouch circle. when it used to load right, it would eventually freeze and not turn the screen back on. when i do the hard reset, it shows the reset happening, turns black and the only way to do anything is pull the battery and put it back in..after i turn it on, it shows the reset screen again, eventually it shows the welcom screen and whatnot..but then it just turns black and there i go in my vicious little circle again...and ive have google play for like two days and ta freakin da. dammit. please help?!

hi thanks for your information

ok so were do i start why do you have to take your sats to be a damn member but if any one has this problem on there mytouch check out this site (http://forum.xda-developers.com/showthread.php?t=1234604) and follow the link on the page to see if you got a bad eMMC and if you do it is farly easy to fix it just takes a little time ohhh by the way if the splash screen is froze you might need to go tru adb wireless (http://forum.xda-developers.com/showthread.php?t=928370) and then it can get a little fun but turn your my touch off with battery in and pluged in usb and use adb from there and pull the command promp up and type ( adb reboot recovery ) and it shuld bring it back to rom manger just wipe data and load new rom turn it on and your done pat your self on the back and light a doobie
