Hey guys, so I just came across a Nexus S GT-i9020T but it has a problem! The problem is right after it's turned on, it immediately goes into "Downloading... Do not turn of target!!!" with an android sweeping up icon... Now I just bought this off a guy and he only told me that the last thing he did was install some Cybermod 9 skank mod??? he claims the phone was working fine until he went to reboot and got this Downloading.. screen from there on out.. Now I can't even get the phone recognized on my Windows 7 computer but I'm really new to this stuff and thought if i could get this fixed i'd have a cheap new/used Nexus S.. I've tried the Volume Up + Power hold, and other variants and cannot get the phone into bootloader. Also, when I plug in the USB cable there's no charging icons, and it seems the battery is getting low and dying so I'm going to buy an external battery charger to keep it topped up while I try to repair it. Please tell me what I can try to get this thing working! Thank you!
