[Thunderbolt Q&A, Help & Troubleshooting] Pete:
Hello everyone. This is my first post on XDA. I've been lurking for a month or two, and have decided that XDA is the place to be!

I've had my Bolt since April, and like many others I am very frustrated with it. The OTA back in May/June, the one that caused all the random resets, made me start exploring and discovering this thing called 'rooting'. Back then I felt that rooting was a risk I didn't want to take, yet. It reminded me a lot of my Dish Network days, where keeping up with ECM's was an ongoing hell, and I just didn't want to go back there. The OTA after that fixed the resets, and bought some time while I researched rooting.

For the most part, it seems like most of the problems are software related, and the hardware is just being held hostage by crappy coding. BUT, it also seems like most every TBolt owner is on their third device because of hardware issues. I don't want to trade up for a less-than-new device. I did go through an authorized reseller, and bought a year-long, no questions asked warranty, so I can play that card if needed.

My dilemma is that I am ready to root, but if I have bad hardware, I want to return an un-screwed with device. I know that I can unroot, but it would be my luck that it wouldn't go well. And believe me that I considered modding it just to see if it is the hardware or not.

ISSUES: I have various quirky things going on that are obvious software problems, like texts going to the wrong people, butt-dialing (once), CPU lock-ups, erratic scrolling (browsers mostly), software lags, etc.. I think the touch screen, though hardware, is controlled through SenseUI, which has really contributed to my wanting to go with AOSP. The biggest issue I have is with the data connection. I've read a lot of threads on this that have ended in numerous solutions. The most common culprits seem to be the SIM card and the battery cover (idiot design btw). Regardless of whether I am in a good coverage area or not, I have the classic ... 3G..1X..3G..nothing..1X..1X..1X..nothing..3G..nothing..1X..etc. This was really terrible before one of the OTA's, after which it seemed to settle down. I've also experimented with the modem settings, and also the radio settings. CDMA auto PRL works best. Still unsure about the modem settings. Currently I have CDMA only for preferred mode, Enable for Rev A., and Disabled for 1X diversity. I still experiment with these settings, but don't really see much difference. A detailed guide to those settings would be really kick-ass. One day, my phone wouldn't let me make or receive voice calls. Somehow, a setting changed that set it for EVDO only, really strange.

I use Easy-Tether, and have recently been using a Wilson dual-band repeater/amp. I have also found a most excellent app called RF Signal Tracker, which gives me separate RF meters for voice and data, and also shows the state of the SIM card when toggling Airplane mode. I live a little bit out of the city, so I know that serving towers might be causing some headache. With the Wilson, both meters are around -72dbm, which is decent. In town, without the Wilson, it's a little better, around -66dbm. I will stare at this this thing and watch the EVDO meter bottom out at -120dbm and then bounce back. Sometimes it will stay on 1X (for hours probably if I let it), requiring a reboot (or airplane toggle, it varies). Sometimes, while using ET, the signal strength will be awesome, but I get connection errors like it's not even hooked up, or I'll be typing a lengthy post :) and when submitting I'll get a Connection_Reset error. Sometimes the throughput will blaze (even while streaming), sometimes I'm reaching for a hammer. I have also found that "It works...if i use it," meaning that a data session might start out crappy, but will stabilize. There are times when the data connection is crappy, and rebooting the phone will fix it. And of course, there are many days with no issues at all.

With a hundred different combinations, I can find no rhyme or reason why this handset cannot maintain a data connection with consistency. I'm leaning toward software, but I still can't tell. Others with this problem had their SIM card replaced, which worked, but maybe it was just the battery cover. Is there a fool-proof test I can do that will troubleshoot this? Another possibility might be Big Red Brother compelling me to buy a Nexus.
