Hi! I have a Tablet with RK3168, 1GB Ram (Android 4.2, already rooted) and I want to try to install custom ROM (probably Cyanogenmod). First of all: CWM. Following the guide in androtab.info and using the generic IMG (already installed), I have the following results:

When reboot into recovery, there is a debug on bottom:

On normal android boot, mount cmd gives me:

Quote:

/dev/block/vold/31:9 /mnt/secure/asec vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,g id=1015,fmask=0002,dmask=0002,allow_utime=0020,cod epage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
tmpfs /mnt/sdcard/.android_secure tmpfs ro,relatime,size=0k,mode=000 0 0

And cat cmd:

Quote:

root@android:/ # cat /proc/mtd
dev: size erasesize name
mtd0: 00400000 00004000 "misc"
mtd1: 00800000 00004000 "kernel"
mtd2: 01000000 00004000 "boot"
mtd3: 02000000 00004000 "recovery"
mtd4: 04000000 00004000 "backup"
mtd5: 08000000 00004000 "cache"
mtd6: 40000000 00004000 "userdata"
mtd7: 00400000 00004000 "kpanic"
mtd8: 40000000 00004000 "system"
mtd9: 333c00000 00004000 "user

Now, rebooting in recovery with cwm, those block devices does not exist:

Quote:

~ # mount
rootfs on / type rootfs (rw)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,mode=755)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
tmpfs on /tmp type tmpfs (rw,relatime)

~ # cat /proc/mtd
dev: size erasesize name

Extracting stock recovery.img to look at recovery.fstab I have:

Quote:

cat recovery.fstab
# mount point fstype device [device2]
/mnt/sdcard vfat /dev/block/mtd/by-name/user
/mnt/external_sd vfat /dev/block/mmcblk0p1 /dev/block/mmcblk0
/system ext4 /dev/block/mtd/by-name/system
/cache ext4 /dev/block/mtd/by-name/cache
/data ext4 /dev/block/mtd/by-name/userdata
/cust ext4 /dev/block/mtd/by-name/cust
/custom ext4 /dev/block/mtd/by-name/custom
/misc mtd misc
/parameter mtd parameter
/boot mtd boot
/recovery mtd recovery
/backup mtd backup

Any idea How I can make it work?.

I've posted here since I've don't have permissions to post in the Development forum (cause recently registered)


Thanks in advance.

Thumbs up CWM Rk3168
Hi, what tabet do you have? Cube U25GT Dual-core?
Now I have a tablet Vastking MR733R 16Gb on RK3168, and have almost working CWM recovery for it!
I make this from Impression Impad 0413 recovery.
My tab has 1280x800 screen, 0413 has 800x480 screen and I can get recovery for impad, then with imagerepackerrk I unpack my recovery and 0413 recovery, and after change in 0413's CWR kernel file by MR733R kernel I have a CWM recovery working for My tab.(But screen is corrupted, inversion). Recovery and buttons works good.
Now I'm looking for make screen in recovery good and for TWR, beacouse it's much more comfortable.
Here You can take a recovery IMG file for 0413 https://yadi.sk/d/dq0KqkCGd9nP8
And here is imgrepackerrk https://yadi.sk/d/zVRkirg0d9nSj
