rooted using Root RK29 Tab Toolkit 1.3.
reset and vol + = flash mode rock usb.
RKAndroidToolv1.37 and RKBatchToolv1.7 work for flashing.
used rock usb driver included in either of the flash
tools. when flashing several things needed done to
enable flashing and or adb. do not enable usb storage
on the device. on windows pc used the safely remove
mass storage tool. only on the removable drives that
showed in my computer after plugging in the tablet.
in RKAndroidTool or RKBatchTool use the "switch" button
to put the unit into flash mode. I used RKAndroidTool
to flash the cwm. I tried several cwms, PER5274B_CWM.zip
was only one to boot to recovery for me
(tried many including ones from developerof cwm, just
happened to find one to boot after trying
over and over). so far. succesfully made full backups of
the unit to sd card. obviously mount the ext sd in cwm
first before backing up to sd. succesfully flashed
gapps-jb-20121011-signed.zip using PER5274B_CWM.
the stock recovery tool rejected all gapps. note gapps
sometimes closes for no apperent reason with no error.
all other gapps versions i tried crash soon as i
cwm file working so far PER5274B_CWM.zip. have only figured
out how to boot to recovery using reboot apk.
key combo is unknown to me so far. actively trying other cwms.
Other cwm's have booted to a white screen for me.
a word to the wise, make full flash backup soon as you
get cwm on. its the only way to turn back to stock as
far as i know. I cannot find a factory rom for this
downloading cm 10.1 for rk29xxboard now, will report
Cheers hope this helps out someone.
