Stock Thunderbolt rebooting randomly

[adalvare]

I have a stock Thunderbolt that reboots itself around 4-6 times a day. I have around 200 apps, extended battery on the phone. Does any one have an idea as to why this would happen. It also has days where the battery lasts all day and others where it sucks out 25% before I get to work. Any help would be appreciated.

I have had the same issues with my HTC Thunderbolt as well. I contacted verizon via phone, they are very aware of this issue and they told me to hang in there. I have had my phone replaced, my sim card replaced, and my SD Card replaced.

This is what verizon and HTC stated..


I understand how important it is for your Thunderbolt to function properly and I apologize that you have been experiencing the rebooting of the device since the update. HTC and Verizon are aware of this issue and will be happy to assist you.

There are too many of us posting comments about all the random reboots we are experiencing since the OTA update, yet nobody is really explaining what they were doing before the reboot. I'm thinking if we work together we can piece together what's driving our phones to reboot based on what we are doing right before it happens. Hopefully we can at least reduce the amount of reboots if not eliminate them altogether. This may also give HTC some ideas if they haven't already identified the root cause.

I'm proposing a template to minimize the amount of time spent reading through the posts.

proposed template

1. How many reboots have you experienced since the OTA?

2. How many times a day does your phone randomly reboot?

3. What were you doing prior to the reboot?

4. Is your phone setup to automatically search for a LTE signal automatically (CMDA + LTE/EvDo auto) or do you have it set for 3G/1x only (CDMA auto(PRL))? If you aren't sure then you are on the default setting, which is the first option.

5. Suggestions?

6. What city and state are you experiencing your random reboots in, if any?

7. Are you experiencing random reboots over WiFi, 3G and/or LTE?

8. What is your baseband version? Located under about phone and then software information.

I've read through everybody's feedback regarding the random reboots. Some people have more than 5 a day, some only 2 to 3, while others may have been fortunate enough to experience 1 or none. I can't seem to put together any similarities in the information for those with greater than 5 reboots a day to those who have only had one or none. I PM'd people who get a lot of random reboots daily and others who have only had one or none since the OTA and no type of pattern emerged that could lead me to a fix that could least reduce the frequency. So at this point I've concluded that it's not user error related meaning we aren't contributing through user setting and/or applications to what is causing the reboots. So I decided to reach out to HTC via email to see what their front line tech support had to say regarding the issue and this is what they had to say below.

Dear Larry,
I understand you would like to know the cause of some Thunderbolt devices rebooting after the OTA. Unfortunately I do not know a direct answer to that question. If someone's device reboots on them after a factory data reset we have been working with customers to get a replacement device through Verizon or to get service under HTC's warranty.
While I could make educated guesses, they would simply be speculation and I could be entirely wrong and I wish to avoid providing you with inaccurate information. I hope you understand I am not trying to dodge the question.

I'm going to try and get a better response tomorrow by giving HTC tech support a call. If the front line tech support rep can't give me a better answer, then I will ask to be transferred to a higher level of tech support that could further assist me. I will update my post with what they have to say.

After some searching, I ran into this post, that may help shed some light on what we can test to see if it makes a difference and post what we discover. http://forum.androidcentral.com/htc-...-problems.html

I have been having Reboots for over a week with too many to remember. The amount per day I can not say for certain because of my sleeping hours but while awake I average 4-6 per awake hours. It has rebooted while I do all activities. Text, email, web surfing, music etc. Sorry it isn't easier to narrow down.

1. Too many to count.
2. Usually I observe an average of 3....no telling how many times when it is out of sight.
3. It is completely random (reboot while:text, call, web, sleep, etc)
4. Suggestions....yeah, fix the OTA update...lol.

Today I went to turn bluetooth off, left the phone, came back and the phone was off. The phone would not power on until after I pulled the battery.

1. How many reboots have you experienced since the OTA?
2

2. How many times a day does your phone randomly reboot?
1

3. What were you doing prior to the reboot?
The first one happened while my phone was asleep, so I don't know what the phone was doing in the background. I just happen to glance over and noticed it rebooting.
The second one happend when I was responding to a message in the facebook application.

4. 4. Is your phone setup to automatically search for a LTE signal automatically (CMDA + LTE/EvDo auto) or do you have it set for 3G/1x only (CDMA auto(PRL))? If you aren't sure then you are on the default setting, which is the first option.
CDMA auto (PRL) since I don't live in a LTE area as of yet.

5. Suggestions?
New working theory, but I have to track down a rooted user who was experiencing random reboots until he switch his basebands, claiming that his random reboots stopped.

6. What city and state are you experiencing your random reboots in, if any?
Hesperia, CA about 1 hour outside of Los Angeles

7. Are you experiencing random reboots over WiFi, 3G and/or LTE?
I think my two reboot have only occurred over 3G

8. What is your baseband version? Located under about phone and then software information.
1.16.00.0402w_1

I can confirm many reboots on 3G/1X.

[Larry_ThaGr81]

I can confirm many reboots on 3G/1X.

Well that throws that theory out the window.
