Hi everyone! My friends PSP-2000, Which i tried to reset to stock so I could update it to 6.60 PRO-C3, but his charger was faulty and crashed while downgrading to 5.50 OFW. Now when it turns on, It is blank, and won;t even enter the recovery menu. It was 5.50 GEN and I tried using XGEN. It doesn't have a battery, and my PSP is a E-1000. How to fix?
