The <hw_id> is the product HW revision, which is a 4-digit code. Both product code and HW revision can be found from the type label of the device to be flashed. The type label is on the back of the device, underneath the battery. )
3- Disable R&D mode: flasher-3.5.exe –-disable-rd-mode
4- Insert the battery and reboot
Hope this will help.

Then flashing it again was easier. Now it's back to normal. Thanks
