Some months ago I installed CM10.1 on a Samsung Galaxy Tab 10.1 (PT 7500). My son and wife were using the tablet most of the time. Lately it became very slow. So I decided to go back to factory settings. I did this via the "system setting" -> "backup/restore" -> "factory settings".
After rebooting the android logo with the blue, rotating sphere came on screen. After 3-4 seconds the blue sphere stops rotating and 10 seconds after that the tablets reboots again. This loop continues endlessly.
After a while I tried to boot to recovery (holding the power button and the volume down) and I'm getting two images on the screen. One with a box and small android figure (left) and one with an android figure with the text "downloading..." (right). With the volume down I select the box image to go to recovery and all it does is reboot to the animating android logo with the blue sphere. So, at this moment I'm stock.
Does anybody know if there is a solution for this?
