Scroll Extreme - Extremely Broken

[BuddyMatt]

Hey guys,

I've knackered my scroll extreme. Not sure how, but i manged to stop it loading my user-data directories correctly. Tried to fix it myself, and basically borked my boot image

i've emailed Storage Options, as i can still get into recovery mode, and figure that if I can lay my hands on an update.zip I can flash a firmware and everyone will be happy.

But, just in case storage options don't get back to me or aren't willing to supply a copy of the stock firmware, I don't suppose anyone around here has any bright ideas?

If you can get a firmware image out off Storage Options - that will be a first.
From all the posts on the Extreme to date I haven't seen anyone who has got what you are looking for.
Hope I am wrong - but I am sure others will confirm this.

I guarantee you 100% you will not get the firmware from Storage Options.

You could tell us what you did and maybe we can try to fix it...

Does your Extreme actualy boot to the OS?

[BuddyMatt]

It did, but wasn't correctly mounting the /data or /cache dirs, so was always mounting as fresh install with no space to customise. I worked out what the mount points were through ADB and discovered that if I was quick I could mount /data whilst it was booting and sort of get all my apps back.

Anyway, as I'm prone to the little bit of knowledge is a dangerous thing mindset I figured I could rewrite the init.rc to mount stuff on the way in, so extracted the ramdisk boot.img, edited the file, repacked the boot.img, and copied it back over the top of where I first got it from using dd

So, yeah, that didn't work. I can boot to recovery, but that's it. Trying to boot the OS proper gives a black screen, and ADB won't connect.

I still have a copy of the original unedited boot.img, although I'm unaware of any way to flash it back onto the tablet although it might be possible through adb whilst in recovery???

[suggsy89]

If you can boot to recovery cant you dd the original back?

I have found a clockworkmod recovery that if you are feeling brave would like to flash aswell

[suggsy89]

No you wont be able to dd it back, you will have to cat it back...

Code: Select all

cat /sdcard/boot.img > /dev/block/nandc
sync
sync
reboot


That should do the trick, if not youve also borked your system partition

[BuddyMatt]

yeah, adb shell is giving me

- "exec '/system/bin/sh' failed: No such file or directory(2) -


maybe fastboot is an option? though no idea how to get the tablet into that

[BuddyMatt]

if i could give it a shot i'd love to get a cwm bootloader on the tablet, if nothing else would give me a backup option... assuming I can ever get it going again

[suggsy89]

No fastboot option, Allwinner uses u-boot not fastboot

[BuddyMatt]

blast

just succesfully pulled off an adb push sh /system/bin/sh (got sh from another android dev) but alas, i then got permission denied on adb shell

feels so close to finding a solution to the issue!
