Anyone purchase a Scroll Excel recently?

[ptbw]

So in theory that is a fully working image?

In theory yes.... I just want to confirm that a "new" Excel basically loads the same modules as I have used.

I have checked the backup and none destructive functions and they all appear to work fine. Just need to ensure I have a way back to a working tablet.

I am concerned that there is no flashable image for this tablet to restore if it all goes pear shaped.

I guess Livesuit with the tablo image followed by a CWM restore should act as a fall back position as long as the kernel and boot image are identical, what do you think?

...
Hope that helps, if I did it wrong I'm happy to try again, new stuff to me.

I have the file and can see the contents thank you.

I assume this means that you have installed CWM?

I find the most reliable way of getting into CWM is to hold the menu key then power for a count of 10 then release power then menu.

If you connect your PC at that point and type adb devices you will set the device in recovery but the screen is blank.

The good news is I have found a solution BUT the fact that CWM did not work on our tablets means that I would be VERY careful about trying roms or anything else as the hardware is different from previous models.

I am still testing the solution and hope to have something to try this evening assuming RL does not get in the way.

i have used the Tablo via livesuite then cWM restor to get back to GB from ICS but that was when we were sure the Tablo had the same hardware
if you have a dirfferent digitzer then you could end up with no touchscreen when you flash the Tablo firmware

saying that i under stand that you have a working CWM via comand line so if you have a backup you might be able to recover with adb

i will look at funs thread as i remember someone lost screen on that thread and fixed it

In theory it will work, i flashed the tablo rom to my "Old Excel" then used your backup, but had no display, it booted up fine though, so i swapped some modules out of /drv and rebooted... everything works.. except that the camera force closes, so as long a you have a backup, you should be fine.

Oh and yes the lcd is deffinatly different, maybe the keys not 100% sure.

I'm glad it worked.

I assume I have CWM on there as I got the same message as in a successful screenshot in the install thread. Is there another way I could tell? Should there be files in the /data folder on the device?

I see I could probably get into CWM by connecting to my PC but TBH I'm very weary about doing anything with it at the moment as there is no easy method of recovery. I definitely won't be trying any ROMs.

Thanks for working on a solution, much appreciated.

The "original" recovery does not have a /lib/modules directory, it will exist if CWM has been installed to check you will need to use adb and mount /dev/block/nandf just like you did when you installed CMW.

I have started a [FIX] thread for this which has full instructions. But basically it takes your original module files and copies them over the broken modules. viewtopic.php?f=55&t=2435

Thanks for that. Sorry, I don't understand it though.

When you say "use adb" does that mean as in your reply above, try and boot into CWM and then connect to my PC? Where do I type adb devices, the command line? If I do that, and it works, how do I get it out of recovery?

Do I type mount /dev/block/nandf into terminal on the scroll itself or on my PC?

Apologies for my ignorance. I'd just like to be clear about what I'm doing before I tinker with it again. When I installed CWM it was just a case of right clicking on a .bat file which I can handle.

Ok I will try and explain a little better.

The tablet has got two distinct areas one is normal boot this is where you end up if you let the tablet power up normally. The other is recovery, ( think windows safe mode but with a completely separate set of files). You can't do a great deal in recovery but its handy as a way of backing up the main area or updating it.

Installing CWM on recent Excel tablets succeeds but because of hardware changes you can't see anything on the screen in recovery because it was designed for different hardware. So by taking the drivers from a working Excel and overwriting the bad ones CWM recovery now works. Note this only affects the recovery area the normal area is not touched, so you still have a perfectly working tablet.

-------------------------------------------------------------------
If you just want to check that you have CWM recovery but just can't see what's going on do the following:
Boot your tablet normally and ensure you have USB debugging enabled, (Settings/Applications/Development)
Then plug in the USB lead.

On a windows machine do:

Code: Select all

open android-sdk-windows folder on pc
right click platform-tools folder and open command prompt in there


You can then type:

Code: Select all

> adb devices
List of devices attached
20080411   device


If it fails check you are in the correct directory and the tablet is recognised by Windows.

Now type:

Code: Select all

> adb shell


This allows you to enter commands directly on the tablet

Code: Select all

mkdir /data/recovery
mount -t ext4 /dev/block/nandf /data/recovery
ls /data/recovery/lib/modules


If it shows a few lines ending in .ko then you have CWM5 installed.

At this point if you did unzip the file to your sdcard you can copy the modules from your sdcard and then unmount the recovery partition.

Code: Select all

cd /data/recovery/lib/modules
busybox cp /mnt/extern_sd/modules/*.ko .
cd /
umount /data/recovery
rmdir /data/recovery
exit


OR if you are not ready to proceed just unmount the partition.

Code: Select all

umount /data/recovery
rmdir /data/recovery
exit


------------------------------------------------------------------------------------

If you want to see if its booting into recovery when all you see is a black screen do the following:

Power off the tablet and remove any USB lead

Press menu then power and hold both for a count of 10, release power and then menu. If you have the later build of tablet then your screen will remain blank.

On a windows machine do:

Code: Select all

open android-sdk-windows folder on pc
right click platform-tools folder and open command prompt in there


Attach the USB lead and at the prompt type

Code: Select all

> adb devices
List of devices attached
20080411   recovery


If it shows the above then you are in recovery.

The easy way to leave recovery and return to normal is to type:

Code: Select all

adb reboot


and the tablet will restart and boot normally.

I hope this helps.
