i think my treo 750 is dead

Hi everyone,

I have a big problem and I need urgent help please. I have ATT 750 unlocked and I'm outside the States now. My Treo was 6.0 then I upgrade it to 6.1 so far so good.

Then I saw a custom rom that I thought it was interesting. the custom rom was for HTC Dimond I think. without paying too much attention. I started the upgrade. It went 70% before the upgrade crashed.

Now my Treo is not responding to anything. I have the original ATT 6.0 SD upgrade and I have the 6.1 lite upgrade. I'm using CheetahUnlocker to flash the SPL (that is working) but when I try to install the 6.0 or 6.1 using Kaiser Custom RUU v1 it crash.

I saw the post above that suggest to place the original 6.0 on a freshly formated SD and install from there. that is not working either. when I try to install the software it goes into these steps before it crashes: btw, I have the tri-color bar and it has the following info:

CHEE100
IPL-0.20
SPL-1.40.01iNex

while update in progress i see the following:

CHEEIMG.nbh

SPLASH1 - OK
BOOTLOADER - OK
GSM - OK
MicroP - OK
EXTROM - Fail
OS -

After the crash I get this msg: "Update Terminate Update Failed"
Any suggestion please? need more info? then let me know

You may have corrupted your DOC, you may need to use mtty to reformat it. Do some searching on how to do it.
Or try to use T750URT.exe to restore it, it comes with the Treo desktop updater.
