How to Install Clockworkmod on the Scroll Tablet - NOT Excel

[relkari]

Or possibley a original recover img

[gadgetuk42]

Hi Just got my Gen 2 8" tablet today, am having exactly the same issue with booting into recovery mode:
hold the UP volume button and then hit power release UP volume button when white screen and Scroll icon appears, White screen and icon stay on screen and nothing changes, have tried Volume Down and a whole other sequence of keys but still the same, powering off the unit and back on again thankfully results in a normal boot, also should mention that unit is running 1.02 and did not have the /system/etc/install-recovery.sh was not present.

Any ideas?

Hi everyone,
I have exactly the same problem as Linzi my firmware is 1.02s, Model number is SCR051625.

I'm a bit wary of returning it to Maplin as, like Linzi I can't do a factory reset (which means I can't remove my Google account)

I'm not convinced it's a hardware fault though as everything else works fine.

Going to try trawling the XDA forums to see if I can figure out a fix. Will let you know if I find anything.

Take it back to maplins, if SO reckon it should have a recovery system then its faulty... Maplins are too daft to notice!

Mine has the 1.02s firmware and will only boot into normal mode now, recovery just hangs.
I had no errors when flashing and manually running the install-recover.sh gave no errors at all.
do any one have a copy of the standard recovery.img I can try and flash with in case I need to run recovery mode?

I to have installed this on 1.02 firmware and nothing happens when going in to recovery mode is there a fix for this ?


Thanks

[evilbobbins]

same as mine did, mine has just died a death though so will if I can get a replacement I'll try and post a standard recovery.img that "might" fix the problem until clockworkmod works on 1.02

[hardmaninc]

Yes please I only got mine today so don't want to take it back if I can help it

DO NOT FLASH CWM - If you have FW v1.02

If FW is v1.01, 1.00, 0.94, Check for any of the following files on your Scroll: - (they may not be there - but check 1st)

1. /system/etc/install-recovery.sh
2. /system/recovery-from-boot.p

RENAME - Them 1st (or delete them, but renaming them, means you still have a local copy if they are ever needed in the future.) Otherwise problems will occur when flashing CWM - (More so with scrolls that have FW v1.02) - You will need to have your Scroll rooted to do this and use a program like root explorer.

NOTE - This might not be the main cause of problems with flashing CWM on to scrolls with FM v1.02 - But it is best not to have them there, named as they are at present on you scroll when flashing CWM - Or even after you have flashed CWM, regardless of your firmware version)

INFO - Below is just some background information on what those files do.

### Start of info ###

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.

### End of info ###

I hope this post helps

When I first tried the files in question were not on my scroll putting them on did not do anything either so was stuck either way

off to try and get a replacement on my lunch today
