This is my first chance to handle and use a 9742, and my impression is that it is a very nice tablet. This tablet belongs to my new neighbor and while troubleshooting, the tablet rebooted out of recovery after about a 2 minute timeout. This tablet came to me for test with a completely dead battery, and the owner lost the charger. Plugged it in to usb and charged for several hours. The tablet boots and runs normally (wifi connects, able to browse and play video). But the setting page battery usage data is not available. Factory reset the tab thru setting/backup and reset, During this reset, one can observe the green android robot, with the spinning wheel and it automatically reboots to system, but with the same symptom. At this point, I turned tab off. Then manual boot to recovery. The stock recovery seems to flash by, but then, the green android robot appears with no text and a red triangle and exclamation point in the middle. Tried pinhole reset at this point to no avail. Tab simply restarts. If pinhole reset is not pushed, after about 2 minutes in the recovery with the red triangle, the system reboots on its own. I have 2 questions at this point. How can this problem be solved (no batt data) and is this related to gen4 recovery time limits. I know cwm recovery would probably solve the problem, but he asked to keep it stock without even rooting.
