Hello everyone, after I did 132 searches and tried everything, I will ask for help! I have an iPhone 3GS. I do not know the initial carrier. I had it unlocked and jailbroken but deleted everything by pressing the erase all content button. I do not know the last firmware, nor the baseband. I only know it was a tethered jailbreak before. I followed various instructions a few days ago to do a restore. But whatever I do (tried many firmwares, last one used was 4.3.3.), there is no chance to restore the iPhone without getting the message. The device is not eligible for this built. I know, you guys propose to delete the host files. I did that. Still no chance at all. Please help me, I love this phone (actually this particular one) and although I have an iPhone 4 to help me out, there is just no chance I would use it rather than this phone. Please give me some advice Thank you so much for any help! From what I have seen in this forum, the support is just incredible!
