[DEV][UPDATED] ota update.zip with root and 'rescue-backroor' builtin! [not-released]

condi · Mar 5, 2012

Hi guys

Treat it as a small curiosity. Nothing special (I think?

)
First custom update.zip done with Sony Tablet S

Its useless for now. We still need a lot of work.
But remember - a small step forward, small progress,
and the target will be achieved

--------------------------
UPDATE
--------------------------

Hi again,

Today I show you capabilities which will be easy to get,
when we will get disable-signature-check in recovery.
We can't do that for now. Method I use is 'little' more
complicated, not easy. Let's wait for ICS release,
then I'm gonna make custom update zip with root incl

Take a look at movie below

Nicely done!

Judah001 · Mar 5, 2012

Was it my PM that motivated you lol. Good stuff Condi!

Nesquick95 · Mar 5, 2012

Nice work!

Well done...
Don't need a complete custom ROM for now, I think that a one line script with set_perm_recursive to 777 on /system should make all the poor #10 kernel build owners very happy!

Keep, the good work thanks

grcd · Mar 5, 2012

This is incredible news! Bravo!

Hi my friend,

that sounds really good ... what would be the next steps?
Could you explain how you did reach this goal?
It looks very promising ...
Please keep us informed ...

Since we now have a SIGNED flashable update.zip, here is a little something I made to install busybox, su, symlinks, etc to root the unrootable kernels. The problem I am running into is signing it so it will pass the signature verification. I attached it for all to use and attempt to get it signed and runable. I only ask that you don't change anything in the flashing script untill you contact me. Thanks...

We dont have signed update.zip. Who said that its signed zip?
The script is nothing new, i had few updaters with root install,
I've got already my newest ota with root included.
Your script has bad syntax, it will not work.

If i could sign zips with sonys private key, then i would already release root tool,
And also a lot more..

As I wrote in first post, there is a lot of work to do.

Hi Condi,

could you explain a little bit more what and how you did to avoid misunderstandings?
On a first glimpse it looks like a 'faked update.zip' who gives you/us the opportunity to install additional stuff via recovery. If this would be possible, it gives us a lot of possibilities.

For now its not useful for 'end-user'. This can't be done without root already.
Everything what can be done via updater-script, can also be done in normal booted device - rooted device.

Until we could manage to modify/decrypt system.img, hidden.img - all the blocks, then its not useful.
I will wait till ICS will be released, this could be our kind of 'OTA-RootKeeper' for ICS

Then I think that I could add this future, as automatic tool in ALLinONE tool.

The zip you flashed is called update-signed.zip, leaving the illusion it's a custom signed zip...
We need to find a way to modify the recovery to bypass the signature verification. After that, no encryption necessary. As for the
syntax error, i will look at it tonight after work...

Nobody - in any forum, in any device I know - has bypassed Recovery Mode signature verification. Devs just made custom recoveries (CWM), but the default recovery needs always signed update.zips
We need a custom kernel to include custom recovery.
But to make a kernel we need SOURCES, which we do not have.
Maybe Sony will release ICS souces.
With Honeycomb there were some restrictions...and even Google haven't released sources for Honeycomb, but I hope it will be different for ICS...

@sebarkh
Some hints.

Here you can see that the stock 3e recovery can be modded to disable the sign check.

In one of the dev toics was the source link posted. I mean the sony website and kernel sources.

That's exactly it. There have been devices that have bypassed the signature verification using 3e recovery without using cwm... Which was the base for the custom recovery i was working on till i got locked out because of kennel 10. I'm not a noob here guys...
With the sgs4g, we had the same issue with sources, kernel, recovery, signature verification, etc. but we had more dev's which made things move along faster.

We need the recovery binary (which i have), root, and the true location of the stock recovery (tried bypassing and using the typical directory) and it will be done. (Hell, I've already got it somewhat working.) Then we can create a zip based cwm that you keep on your sdcard.

you wrote you have the recovery binary.
have you dumped somehow from the tablet or it is from other device?

I meant Original recovery... You are linking to MODIFIED recovery...
With original recovery you will never be able to install anything without a key to sign it.

THX for links!!!
So .. if we have sources maybe somebody who "knows how" could build a kernel? Are there some problems with it? Or maybe nobody knows how
