I had a Storm 9500 which I updated to OS5 a while back, but it gave me problem so Celcom gave me another unit, but with OS4.7. I've been trying to update it to OS5 for a while now, I have downloaded and installed the new Device Manager, then the new OS, deleted the vendor.xml file. somehow, I still can't get around to get the OS loaded on me unit.

Can someone help me please? I have forgotten how I installed it back then.

Thanks.
