Help! My XDA Exec aleatory stops in a black screen after soft reset!

[wfreed]

Hi!
Please someone can help me?
I have a O2 XDA Exec with a SDHC 8GB...
I'm the second or third user that own this device. Because this, I don't know about roms upgrades with precision, but it's running WM5.

All was work fine... But some days ago, it was stopping in a black screen when I perform a simple soft reset...
I tryed remove the battery, all the cards (include the simcard), but the problem still there...
I tryed a hard reset, but the problem still there...
I tryed all that I know, but the problem still there again...

Trouble details:

The O2 XDA Exec aleatory freeze in a black screen after soft reset.
I persists pressing Reset key with some seconds intervals, untill it (aleatory) turn on the screen and load WM5.
The Bootloader and the HardReset screens comes normaly when calleds.
When I perform a hardreset, immediatly happen an freeze without the new system never was loaded before.
I disassembly the device and test the RESET key... there is no problem.
My big suspect is something corrupt in device's bootloader or other "BIOS" program.


I use many PDAs for a long time (8 years ago), but never see nothing like that...
Seed someone something like this before?
How can I solve this problem?
Can someone help me please?
Thanks a lot.


P.S.:Please, excuse my poor english...

Hi, orb3000!
Thanks for your very quick answer! :)
Are there real chance this solve this kind of trouble?

Suggest someone a good, quick and stable WM5 rom to I try?
Are bootloaders upgradibles without need all rom update??

I'm trying understand what is happen. All we knows no erros are acceptable in ROM (firmware) upgrade... so...
Can someone explain to me how is made the XDA Exec (HTC Universal) boot routine??

Eg: In x86 PCs, first it load the bios, the bios load the setting that said to PC where is HD, the bios load the Master Boot Record with partition table, the partition table said to bios where is the active unitie with FAT, the active FAT said to bios where is the boot file, the bios said to processor load boot file to the ram and execute, etc.

Thanks!

I solve my trouble reflashing my WM5 rom...

I used the Jwrightmcps Crossbow ROM Update 2.12.08 WWE, very fast and very stable WM6 rom! Realy a amazing work by our friend Jwrightmcps!

Including, I want suggest here that all those that still suffering in WM5 (living slowly with crashes, troubles, crashes, more troubles and this poor and slow system), try reflash your HTC with a rom like this... my device reborn!! It was dead more now is alive!!! And much more fast and stable! Before it is slowly my old Jornada 720 (206MHz), but now it realy seems have 520MHz!

Thanks a lot for all.

The link for this excelent work is HERE:

(Download the apropriate rom to your device, folow the instructions and EnJoY!! Be HaPpY!!)

This rom don't supports 8GB SDHD cards, but download and Install 2 cabs below and it will support it:
