question

I have a custom gingerbread rom with a custom kernel and a i9000m modem.

Let say I make a nandroid backup and flash ICS.

Can I restore to the exact same state (kernel/rom/modem/data)? Will flashing ICS change my modem? What about the internal SD card will it get wiped?

Same question , I am now on ICS beta 2 and cm recovery 5.0.5.
If I want to go back to Amestris 2.3.5 ROM, can I do that just from nanodroid restore, or I must flash some stock Rom with ODIN, then flash root to get back recovery 3.0 ?

Thanks a lot!

That Phone-Warning-PC screen of death is quite an annoying little bugger.
Solved & learnt ^^

These need to be replaced by one which does not check for signatures. Something similar to what is described here. But our file system is different. I haven't poked around further but I think we can downgrade the entire system to a stock Froyo and the install CWM.
Let's work this out.

Stock Froyo 2.2 UGKC1 also has the 3e Recovery which won't install CWM.

So any idea of how we can get around it then?

I tried the CM7 flash instructions, went into a boot loop and had to flash back the zImage from KG3 to get it working again. What can we try next?

Cool.
My balls went on vacation after the boot loop fiasco, I'll try again soon I hope.
I wonder what changes I need to make in order to just flash plain CM7.1 instead of the ICS build?
Also can this be done with heimdall on Linux?

Thank you again OP.

@AllGamer : a few questions...
1) If coming from UGKG3, why do you repart with 512.pit when flashing JVP ?

2) Is there a reason why you chose JVP over JVR or JVT for example as those GB flavours are also easily rootable with the CF-root/Semaphone kernel?

3) Correct me if I'm wrong, but in both OneCosmic's and TeamHacksung's version of ICS for SGS, front cam doesn't work well. Knowing this, does FaceUnlock work on our i9000m?

The whole point behind this post is : i'm running JVT and the device has been already rooted and CWM is installed, so I just need to go through the last steps of installing ISC, right?
