[HTC Vivid, Raider, Velocity] Tinger138:
Problem during ics update

First, I want to thank jerrycoffman45 to provide solution.

Second, I would like to share my experience with everyone who may have the same situation.

Third and the last, I would like anyone to comment on why my problem was happened at first place.

Here we go:

I bought Vivid in early March. After two weeks, I understood that I need to make overseas trip. I first contact ATT to unlock my Vivid. They declined. I have to buy unlock code from Internet in order to use international carrier's SIM card. During my trip by using non-ATT SIM card, I found that my phone occassionally reboot. Since it did not interrupt my routine, I did not really care and thinking it may be cured in future firmware update. Last weekend, I found out there is RUU ICS available from HTC. I looked through HTC site and understand that I can upgrade my ROM by downloading file to my PC and run it. I have nothing to do that day and the ICS is attempting. I download both HTC sync and RUU 3.26.502.56. and run it. Everything went thru like silk. After reboot, I started to get my App installed sync my contacts from Google account. I was happy.

The second day, I was listening my Squeezebox music and thinking I should install the controller App in my Vivid. So I did. The program did not perform like my GB version. The screen just flashing. But, that's OK. It is not that important of an App. Since I have an Android Tablet which has the same App and run well. But, the third day after I update, that morning I think I probably should reboot the phone to get fresh start of the day. The phone only reboot to HTC screen and sit there forever and it refused to turn off. I need to take out battery. I tried couple of times. The result did not change.

I called HTC local tech service line. They guided me through rebooting to fastboot screen and ask me to perform factory reset and told me that I should wait for 30 minites. I asked they guy what if it won't work. The guy told me it may take 8-10 working days to get service completed. Since I will be leaving for the States in 10 days, I want the guy to confirm if they can complete the service before I leave. The guy pre-warned me that I need to pay at least $35 USD for inspection. Maybe I don't need to pay any replacement parts since it is under worldwide warranty. Later, that day, he called me back and told me the good news is they have parts for Vivid here, the bad news is Vivid is AT&T exclusive they won't honor any warranty. So, if any parts involved I have to pay. I decided not go for their service for fear that they may not finish job before I leave. At the same time, I think it is the software problem, nothing to do with parts, etc.

I came to XDA and look for help and read a few threads and try jerrycoffman45 solution. I re-install the RUU. The Vivid worked again. But, I am still wondered what happened of my first reboot after updating the other day. Is it due to my phone has been unlocked? Or, just some strange Apps I installed. If I wanted to install custom ROM, can I just use the tool on the sticky and go from there.

I appreciate all developers contributed here. Without you, the life is just grey. Thank you,
