[Dell Venue] kepalakayu:
The whole misadventure!

Well, I'm totally stuck and lost ... I summarizes:

I can still reboot off the tablet (VolDown + Power)

it starts in DROIDBOOT

and then I can not do anything useful ...

bottom of the tablet, it has the following messages:

E:installer device ignored
FASTBOOT INIT...
installer device ignored
FASTBOOT CMD WAITING...
E:failed to mount device '/dev/block/sda1' as installer partition using fs_type 'vfat'
ition using fs-type 'vfat'
E:installer device ignored
E:installer device ignored
E:no valid installer medium found
FASTBOOT CMD WAITING...
Could not open /sys/devices/virtual/backlight

I am connected via USB,

adb devices

shows no attached device

adb reboot bootloader

replies error device not found

but

sudo ./start_recovery

displayed on the bottom :

RECEIVE DATA ... and a series of messages (on the tablet and the PC):

and then, the tablet reboots and goes into CWM:

top (and bottom) showing:

Vampirefo Intel-based CWM

and below the menu:

-reboot system now
-install zip
-wipe data/factory reset
-wipe cache partition
-backup and restore
-mounts and storage
-advanced

below 3 superimposed images on the tablet screen

OK

- Install the zip is not possible, I placed the zip files on the SD card is not accessible

- I did the factory reset but it did not change anything (except that I lost my data and settings, no matter ...)

- In all manipulations I lost the backup, so ...

- If I want to try to mount my SD Card, the following menu lets me

mount external_sd

but in this case I get a message:

Error mounting / externalsd!

I can mount the system, it's the only thing that works (I certainly do not want to reformat!)

and reboot, it puts me in a loop display early logo / blank screen I can not get out

- Advanced gives me no solution for this case

If I look at the contents of start_recovery I see:

#!/bin/bash
./fastboot flash /tmp/recovery.tar ./recovery.tar
./fastboot flash /tmp/recovery.envsetup ./recovery.envsetup
./fastboot flash /tmp/recovery.fstab ./recovery.fstab
./fastboot flash /tmp/postrecoveryboot.sh ./postrecoveryboot.sh
./fastboot flash /sbin/partlink recovery.launcher
./fastboot oem stop_partitioning

which make me think that I can flash something eventually

This is encouraging,

but what?

i dunno
