Bootloader Question

[emielfellinger]

Back again with another question.

I managed to flash another working rom on my phone but,..... (there's always a but :):) )
My phone worked great for a couple of hours and then i froze.
Rebooted the phone and 9 out of 10 times it freezes upon boot (t-mobile screen) So i figured re flash... but once i tried the following problem came up.
It even freezes in the bootloader. Most time when it starts and shows the bootloader screen you see a small short line of colors showing up at the top center of the screen.
So now my question is whether its possible that the bootloader itself is damaged/corrupt and if so is there a way to fix it?
Its prob a stupid question because i have read some treads about that on the forum but I could not find any specific to the Tm Wing / Herald.
And i wanna make sure before i can arrange a funeral for the phone :):)

Thx

try to flash to a different rom

Thx,
I tried but most rom's won't work in my case.
For some reason only the original t-mobile rom make my WLAN work.
RUU_Atlas_TMO_US_4[1].10.531.3_4.1.13.37_02.83.90_Ship
And the other one that works is
HERALD.ASerg.12.WM61R.WWE but then my WLAN does not work for some reason.
Most other ROM I cannot get to work because it keep saying either image file corrupt or incorrect hardware ID
But even the bootloader keep crashing lots. So i was wondering if the bootloader is a separate piece of software from the ROM that you can flash and possibly also damage.
I have tried lots of solutions but 99% (of what i can find) has to be done with Active Sync working. Mine does not boot 9 out of 10 times so no Active Sync. When it does it crashes pretty fast. (most time when i slide the keyboard out or when i wanna flash it :) )
But i'm not ready to give up :):)
