CLOCKWORKMOD5 based recovery on Excel

[suggsy89]

Well nandf is definatly recovery for sure, GB rom uses .cpio recovery not .img, but if you have downloaded it from this post, it should be okay, i dont know whats different?

Are you doing it manualy?

I noticed your on Linux.... maybe thats why, cant say for sure though...

Thanks for your suggestions.

Its nothing to do with Linux as I installed CWM5 on the previous Excel manually using adb to push the cpio archive following the same procedure as detailed in the first post.

I then tried using Fun's updated GB cpio file ( slightly smaller than the first one ), same result.

Now I am back with what I believe to be an original recovery image but still with a black screen when I boot using power+menu.

I did save all the nand blocks from the previous Excel, I will try restoring my nandf and see if I get any where.
---- Update ---------------------------------------------------
I have flashed the original NANDF image and I get a black screen.

I have now repeated the install of the original GB cpio recovery archive and if I do the power+menu boot I still get a black screen. However as originally noted I can see the tablet via adb devices.

Code: Select all

# adb devices
List of devices attached
20080411   recovery


PS shows a binary running called recovery.

Code: Select all

# adb shell ps
  PID USER       VSZ STAT COMMAND
    1 root       292 S    /init
   ...
   70 root      4800 S    /sbin/recovery
   71 root      3412 S    /sbin/adbd recovery
   ...
   84 root      1824 S    /sbin/sh -c ps
   85 root      1828 R    ps


Can any one confirm this is what is expected. My gut feeling is the backlight is simply not working in recovery, may be a different LCD panel from my previous device?

Any help gratefully received.

I am way out of my depth here so I am probably talking rubbish but I did read of a case where the display screen brightness had got turned right down so no dialogue could be seen to adjust it back up in brightness.
Apparently this was solved by connecting the Tab via HDMI to a flatscreen TV where the screen dialogue could be seen independantly of the Tab's screen.?

Excellent idea Trashcooky, but it does not work ( I don't know if the normal recovery menu would display via the HDMI though).

HDMI output works fine in normal mode but the port does not send a signal when I can see the tab is in recovery via adb.

This is most frustrating! Next step will be a patched Nandroid exe that I can use to backup via adb. Then restore my old tabs backup and see what happens then.

Its a shame the HDMI output in recovery does not work because at least that would allow me to backup and install ICS.

"BTW I did find this useful patch to allow command line nandroid backups to be taken. (Add back the https)
Code:

github.com/dweinstein/android_bootable_recovery/commit/3fdb0a9b9a08aa8e436e7b0449d0941d8a926465

So I can at least take a backup in recovery"

saw your post on xda can you elaborate and i will include this in the OP cheers

nandroid is a symbolic link to the recovery executable and is the backup restore program.

If it is launched from the command line, it fails because the volume table is not loaded, usually when running in the GUI its done prior to running the backup command.

The patch allows nandroid to be run from the command line and perform a backup by typing "nandroid backup" which was handy because I had no screen!

But once I had got the screen going the need went away...... note I can only build generic executables so it was not going to work correctly in a full fledged recovery, but I was just trying to let fun_ know that it existed. For all I know the patch has found its way into ICS by now.

( Next project a working ICS for this new tablet )

I am the happy owner (two days so far;-) of a Scroll Excel pre loaded ICS - all pretty good so far with lots of tinkering to make it just right.

Am I right in thinking that CWM is not available yet for the new Excels pre-loaded with ICS?

For ref - this tablet has:
ICS (4.0.3)
Build 97F2-D1-H1-H01-1922.20120417

Cheers

[EDIT]: just been looking at topic How To "Flash Android 4.0.3 ICS" (Excel Only) and there does seem to be a version of CWM to use with ICS 4.0.3 so here I go...
