[LG Nitro HD] MRMNYC:
Randon crashes with data loss....

Hi everyone, I'm a relative n00b, so, maybe I'm doing something wrong here. I've been getting really bad random crashes that result in corrupted or lost /data........it's really frustrating. I hope maybe you can shed some light on this.

I'm on an LG Nitro (P930) with the V10f firmware. This happened to me at first on the CM10.1 20130312 build (dirty flashing since 0309), I installed the WIND_Kernel-v1.5_CM10.1_P930 that same day. I chose Smartassv2 as the governor and changed my CPU minimum to 192, and the maximum to 1512. Later that day, the phone crashed while I was trying to type a message in WhatsApp, so, I thought it was just another random reboot, except it was stuck on the Cyanogenmod logo for a half an hour. :(

So, I decided to wipe cache, dalvik, and system, reinstalled the CM10.1 20130312 zip, watched it go through the "Android is Upgrading" screen through all apps, then it got stuck on "Starting Apps..." -- I waited an hour, and no cigar. When I forced a power down by pressing the power button for ~10 secs and rebooted, it stayed stuck on the Cyanogenmod screen. I also tried an older build I had on my SD card, CM10.1 20130311, but the same problems, just stuck.

I finally decided to give up, but backed up in CWM hoping that maybe I'll be able to recover data through Titanium Backup once I did a clean install. I wiped everything (cache, dalvik, data, system) and installed the 20130311 build. I let the system download/install everything and let it sit for a bit before trying to recover data for some apps using TB, and while I was able to recover data for some apps, WhatsApp data was completely gone -- it showed up as an option in TB's Extract from Nandroid Backup and TB would say restore complete, but, when I opened the app, it didn't have my settings or data.

Giving up on recovering this data, I did ANOTHER clean install of the 20130311 (just in case the data recover may have corrupted something), and restored app settings from the restore features in several of the apps themselves rather than TB -- otherwise setting up each app one by one by hand. :silly:

Things were running fine again for a few days (Wednesday, Thursday, and most of Friday). I avoided installing the newer nightlies because I thought maybe that's what caused that issue to begin with. With things seeming to be running alright, I installed the Wind 1.5 kernel, but, nervous about touching the governor, I just lowered the minimum clock speed to the lowest, keeping Ondemand.

Several hours later, the phone crashed while I was typing a message in WhatsApp again (it had been working fine for the past few days). :crying: This time, the problem was a little less bad. I could reboot, system settings were still in tact (Quick Settings panel, screen security, etc.), but, all my apps were reset. Whatsapp data as well as several random app data is gone. I even tried to browse the /data folder but, while the folder structure seemed to be in tact, the folders are randomly empty.... :crying:

So...I know this is lengthy already, but, what I'm trying to figure out is what's causing these crashes + data loss. Is it:

A hardware problem -- like a "disk" with "faulty" sectors? If so, how can I repair?

Bad CM zip files?

Whatsapp, the app?

Wind kernel?

Governor changes?

A combination of things?? I use TouchPal keyboard and JuiceDefender Ultimate. Maybe the radios turning on and off in combination with the CPU load from WhatsApp and TouchPal? I also noticed that Lookout is the biggest battery drain when I was able to restart today...

Like I said, I'm a relative n00b, so, I don't know how to pull a logcat that people often refer to in these things, but, any insight would be really appreciated...and thanks for reading this really lengthy post....
