before you start, you need a actually gnote rom and you need usb jig!! if you not have a jig, dont try this!!!! im not responsible if you brick your phone!!
1. download a sgs2 bootloader(search in sgs2 forum --> bootloader)
2. flash it over odin as pda
3. put the battery out
4. put the battery in and connect the usb jig
5. connect your phone with pc
6. flash the rom via odin as pda
7. when is done, disconnect the phone from pc and remove the jig
8. put the battery out and again in
9. connect your phone whit the pc over the normal usb connector, flashed rom will start with the update, phone reboot self ---> finish
dont ask me, dont look for support, im not developer, i only wrote down what i do and how i reset the counter to 0..
many thanks at bodivas, hi was the first one who try this, and i can confirm it, it works..
