So lastnight I flashed my car back to ie's stage 2 non crackle cause I was tired of the pop sound from the stage 2 crackle 91 octane option well somewhere I went wrong apparently cause when I went to change the launch rpms it wouldn't flash and would say FLASH ERROR NEGATIVE ECU RESPONSE - SEND - 7F-22-31 and then this morning I went to start my car and it wouldn't start nor crank and I put my battery charger on the battery to see if it was a battery issue but even on the charger would start or crank so I dont know what to do or what's going on can anyone help me understand or point me in the direction to figure this problem out. I tried scanning for fault codes with the obd eleven and it didn't scan the transmission and wouldn't let me look at anything involving the transmission like live data etc etc.
