[ej2095]

Hi all

I attempted to install clockwork recover on kids tablet.

How ever it didnt work.

So now i dont have no recovery.

Whats the quickest way to put this back on?

(Teach me to mess lol)

Hi & welcome to the forum,

What make & model of a Scroll tablet did you do this to?

[ej2095]

Doh good point

and Hi Charlie thanks for quick answer

its the 7" scroll

and its build number 97C3-TO-S3-H12-1308-V1

Android version 2.3.3

Now i know why i like my htc hd2 ;-0 (with android of course)

I am guessing from what you have said it's this one:

http://www.storageoptions.com/products/ ... ssential-7

and that you have followed instructions on this forum to add CWM (the only ones on here are for the new Excel and the very 1st Scroll, SO made)

Unfortunately there is no quick why to get the recovery back, unless you have a copy of the original install-recovery.sh file and you put it back into /system/etc (or where ever it was originally in) - I don't have this model of Scroll so I am not too sure.

Ahh good pint i have two of the scrools both rooted so will have a look..

how to flash it back good question

[Charlie]

If you have another Scroll that is the same as the messed up one, great -

See if that has the file install-recovery.sh - copy it to the messed up one put it in to the right place, make sure the permissions are correct, then reboot and you should be back in business. - (You don't need to flash that file)

Note: The install-recovery.sh file can NOT be any file, it has to be from the same make and model Scroll

This should do it, but I can not be 100% sure, as I said before I don't have this model and they may all look the same, but they ain't.

Ta

Just trying to find the thing now...

No search function in exexplorer in the system files... what fun

[Charlie]

This might help to show what I was saying - it's from a post I did a year odd back - (this is in regards to the 1st gen Scroll)

in the init.rc file there is this service call line:

Code: Select all


service flash_recovery /system/etc/install-recovery.sh
    oneshot


Each time the OS boots it therefore runs /system/etc/install-recovery.sh.

Code: Select all

#!/system/bin/sh
if ! applypatch -c MTD:recovery:2048:039c557a915d0952eba272ceddb5824efff621ad; then
  log -t recovery "Installing new recovery image"
  applypatch MTD:boot:5165056:2da0a439bb088865736290b16e8277d47cfd5d6d MTD:recovery 1975102594023372b9758eb4e3dcd288564e6971 5423104 2da0a439bb088865736290b16e8277d47cfd5d6d:/system/recovery-from-boot.p
else
  log -t recovery "Recovery image already installed"
fi


What this does is look at the first 2K block of the recovery partition image and take a SHA1 has of it. If the hash isn't the one shown then it calls "applypatch". Applypatch uses the first 2,875,392 bytes of the boot partition image (headers, kernel, and ramdisk) and the contents of /system/recovery-from-boot.p (a "diff" file) to mathematically reconstruct an image of the recovery partition.

Good luck - you will get there.

very off can not locate the install recovry file??

[Charlie]

It is possible that it's not there, not all firmware versions of that Scroll, have it.

This is a long shot , but I am trying to find you the files needed.

UPDATE: - Sorry I can not find the right ones and I have run out of things to suggest, maybe someone else will be able to help.
