My tablet is stuck on the boot screen! It's a Playtab HD 9 by Kempler & Strauss. It's an rk3026 Rockchip tablet with JB 4.2.2. I've rooted it, but no custom recovery. I don't know what happened to get stuck on the boot screen. Maybe it was using Links2SD. Maybe it was changing the Dalvik-VM heap to 32m (from 16). (Although I changed it to 60m before, and this didn't happen!).

All I know is I spent a full week of my life working on this thing every day, so I would most like to access the OS again to save all the work I did! I can get into the stock flashing mode, but it's just a figure of a green android with a red checkmark. No options.

- Is there any way to get out bootloop without flashing a custom ROM?

- Is there a custom ROM that will work for this? Will an rk3066 ROM work?

- Is it possible to flash a custom recovery; ie. CWM?

I'm familiar with hacking android but not rockchip tablets! Thanks for any guidance!
