My 8125 rom upgrade success story

[jimmyhauser]

I have read all the horror stories, and even though I bought the phone on ebay and have no warranty, I decided to do it anyway.

I plugged into the back usb ports

I disabled antivirus, firewall, network connection, and even stopped all the process I felt were ok to stop

I charged the phone to 100%

I did everything right. As the install was proceeding, it got to 80%, the progress bar changed from blue to red, and stayed like that for 5 minutes. I got nervous, so I went to a different computer to get on this website to do some more research.

I am not sure what happened next, because I heard the little melody that plays when the phone first starts up after a hard reset. So I went back over to the phone to see. I went through the little sequence and got to the today screen.

And everything was a-ok. The phone is even still sim-unlocked, which surprised me. I was told it would have to be re-sim-unlocked after a rom upgrade.

And when it was doing the screen alignment, the little cross hairs were slow and jumpy with the old rom. With this new one, it moved fast and smooth. I am anxious to see if there are other speed increases.

I figured I would share this for the benefit of those who are hesitating on doing the official rom upgrade from Cingular. All my reservations were for nothing.

Congrats! And as for the SIM unlocking ... if done correctly ( read : SIM unlocked) it's not going to "relock"
You followed the steps smartly, disabling un-needed services, AV and firewall, etc. Leaving the computer alone and not minimizing the update screen while continuing to surf the web, etc .. priceless.

Best wishes!

When upgrading ROMS, does it matter if the SIM card is installed into the 8125 or left out? I have SIM unlocked mine and like it very much, but am very tempted to downgrade and do the CID unlock with the older ROM. I have read the forums a ton, but cannot ever recall seeing anything specific to leaving or, removing the SIM card when doing ROM upgrades.

Thanks for any input!! I have learned TONS out here!

it doesn't really matter. the only problem i could see is...

if you use a sim card that does not belong to that locked unit (like a tmobile sim in a locked 8125 from cingular) and try to unlock it, when one of the unlocking programs tries to install itself and ask for permission, you may get problems with constant popups of messages (on your 8125) telling you that you have an incorrect sim.

i just leave my sim out, though i've unlocked it fine before with proper sim inside.

Do you mind sharing what rom did you upgrade too? i have a cingular 8125 phone with tmobile service. I am afraid i might fry my phone...

I dont think your carrier should matter. I have cingular, but my sim is the old ATT wireless sim card. (So my phone had to be sim-unlocked for me to use it.)

It does matter what rom you use (unless you unlock the cid which I did not) I downloaded it from www.cingular.com/microsoft It will direct you to the htc website to download the rom.

I installed the upgrade on mine with the sim card in, and it worked fine and stayed sim-unlocked.
