Custom Sylvania ROM development

[Xi2wiked]

K, I emailed Koushik Dutta about clockwork recovery. Might be donating a device to help the cause......

I have 2 of the EX7 tabs. I have one flashed to 11.2.1.5 beta3 and the other is "out of the box" stock.
I am going to flash the different vers of the 11.2.1.5 rom on to each and see them side by side.
BUT... before I flash the stock one (DG2.01) I am pulling all the folders off. I have rooted it with universal androot. and am running FileExpert to copy them to my SD card them I'll put them on my computer for later comparison. But is there anything I should REALLY be getting? or anything I should just forget?
What should I do?

Can you get me a logcat if/when you do the update? I wanna see just what the system does when it flashes, and where exactly the recovery for this device is.

 

[st0ne]

i can do that on it rooted with ADB or a terminal emulator right?
the command is: logcat if/ ?

 

[Xi2wiked]

Sure lol
I also need to see at what point during boot does the /system/bin get accessed. We might just be able to hijack the boot and get a partial recovery

In early March here's what we discovered when attempting to find recovery and get the update file to burn.

Proceed at your own risk.

Put the update *.ius on your tablet in /local and rename system.ius

Either through the adb shell or a terminal program on your tab run

infoup inject /local/system.ius

You will see it copies it to

mtd2: 08000000 00080000 "resv"

K, nobody try what I'm about to do lol....

Found a recovery in /system/bin going to try to flash a recovery img

Found a recovery in /system/bin going to try to flash a recovery img

Warning, Will Rogers!!

Our device does NOT seem to follow the norm where at each reboot the tablet would copy the 'recovery' to the recovery partition.

/system/bin/recovery is an executable that will wipe the device.

$ file recovery
recovery: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, stripped

 

[Xi2wiked]

Lol its cool, wouldn't flash there anyway

 

[Xi2wiked]

Hmmm......

 

[Xi2wiked]

Got a boot hijaking recovery on my tab..... Now to figure out what buttons to press to get it to actually boot to it lol...

 

[Xi2wiked]

Going to try this.... How To Backup Your Android Phone’s Boot, Recovery And System Partition Images
After I get it dumped/if I get it dumped, im going to explore a little and see whats there to be messed with in regards to the recovery

 

[Xi2wiked]

Im starting to feel sorry for my poor tab..... Lol
All the crap ive been putting her through......
Only managed 4 soft bricks so far, nothing that can't be fixed.

 

[st0ne]

HAHAH I got you beat! I am at 6 soft bricks! LOL! Messing with the prop and the permissions can really take it's toll. but my EX7 takes a flashing and keeps on ticking. (i know... bad pun..)
