Managed to find the solution to this today, all by accident.

Using the magical USB jig used on the sgs to put it into download mode.

Video below shows it

It resets the counter and says that the binary is default, but it is still the custom kernel.

It also removes the warning symbol at the bottom of the screen on each boot.



How did i find it?

Well, you know the download mode jig you can make to put the sgs into download mode. I make them and sell them on ebay to make a few quid. (not too great, too many others doing it)

I thought "it worked on my sgs, will it work on this?"

powered off the sgs II plugged the jig in and encountered a sceen saying "erasing download information succeeded" and now it says I have no custom binaries and my current binary is "samsung official", when its chainfires.

It also removes the triangle warning on first boot because it thinks its genuine. But I still have my root privelages.

I call this a warranty solution. All thanks to a resistor and u micro usb plug.

Where Can I Get One?


Guide to make the jig

MOD EDIT: No selling

I wonder... this resistor value trick came from the samsung anywhere box, which is used for field repairs of phones.

This is the procedure for a SGS1 that lights up but won't boot or go to download.

So tbh it makes sense that this would force it to download, as the box remains the same for a while.

Also this suggests UART loading of a bootloader might be possible, given what is going on in i9000 section in trying to get unbrick working via the usb connector.

That mode looks to be entered with a different resistor value. Perhaps there are other interesting modes we can get to?

Actually on the subject of that, if you run "adb reboot download" you get into download mode without the info at the top, so in theory this phone has 3 download modes.

An install from there still adds to your download count though

I think there is one download mode, but two ways to enter it, plus jig forcing boot into it with a reset...
