[GUIDE] USB jig - resetting the download counter - DM Protocol Version 2.0

---

Since USB jig doesn't work exactly the same way on our SGR compared to SGS II, I recommend an alternative solution.


How to make jig work?

1) Entering the Download mode:

pull the battery out -> plug jig -> insert the battery

or

turn off device -> plug jig -> press power button

2) Resetting the download counter:

Enter DM using one of those two methods above. Once you're there just remove jig, plug usb-cable and install your stock kernel (just to reset the counter) or firmware (in case you want to reset the counter and unroot simultaneously). Right after installation process is started you should see the green text: Success to erasing the record of custom OS! (You can see it on attached picture.)


Remember:

1) This method works only on DM Protocol Version 2.0, for those of you that have v. 2.1 USB jig won't work at all. In your case procedure is more complex, please visit this thread:http://forum.xda-developers.com/show....php?t=1528256

2)You don't have to flash the whole fw-package to reset the counter. It's ok with just stock kernel (only the .tar file though and remember that replacing the kernel WON'T UNROOT your device. To unroot and clear the counter you should reinstall your stock firmware!)

I attached some stock kernels. Please don't ask me to add more. First of all I don't have them and second... you can easily get your own by replacing boot.img from one of the tar-packages below with the original one from your preferred firmware. (USE Total Commander, don't extract packages, simply open them with [ENTER] and copy file from one package to another (F5))

I am trying the second method (insert jig and press power botton), not working. After flashing custom ROM (kernel), it simply reboots as expected (should I disable reboot option in ODIN?).

Would appreciate if someone suggests how to do it right.

Excuse me, but can you write step by step what you did. You cannot enter Download Mode? Or you entered DM and flashed FW but it didn't reset your counter?

Make sure that USB-debugging is checked.

1)enter DM with USB jig
2)remove jig
3)plug usb cable and flash STOCK firmware

It has always worked for me that way.

(Maybe I misunderstood you but...why should you disable auto-reboot option in Odin. Flashing custom kernels increases counter and it has nothing to do with the method I posted above. IT's actually totally opposite. This method is only useful if you just want to erase flashing record, but it won't let you have insecure kernel and 0 on counter.)

I put USB jig in, pressed power button, phone went to download mode.

Tried uploading custom kernel, it wasn't doing the trick. However as you suggested, installing stock ROM worked! But thats quite weird as in SGS2 it works just by inserting the jig.

I agree it's weird

Hello.

I don't want to be off topic but, I would like to ask you when you flashed 2.3.6 from 2.3.4 or 2.3.5 , did your download counter increase?

Of course not it never increases when you flash stock firmware. Only if you flash custom software (with the exception of custom recovery like cwm) via Odin e.g. insecure kernels, custom roms etc.

hey kochan could you shed the goodie on where you get the stock 2.3.4 rom? i tried legion's stock KK5 without getting the magic green words on my screen after the the install kicked start... *frustrated*

I'm flashed 2.3.6 and this tutorial works just fine.

I did the same two days ago with 2.3.6, and everything worked as it was supposed to again. So you must check the jig.
