i followed 5 different guides but still no luck.......the worst part is i have an at&t sim and it still doesnt work.......i think i messed up something with ieraser or the secpack.......any idea? also no wifi.......and sometimes iphone takes too long to respond to the touch screen
Hey guys, lets see if i maybe can help you all out, its the least i can do after all the things this forum has done for me!
A couple of weeks ago i recived a brand new iPhone with firmware 1.1.1 , everything worked fine with jailbreakme.com and it was all great, until i by accident pressed the home button durin anysim 1.1 flashing the baseband, after that the phone was really in hell!, no sound, wifi, bluetooth, imei or anything!.
I been tryin tons of diffrent solutions but they all ended up in the same result, broken baseband and the secpack was in hell to , so what was i 2 do, Well here goes
I tought, wtf happens if i upgrade to 1.1.2 , maybe everything will be repaired ?, well its not workin now so its worth a chance!
So i rebooted the phone into recovery mode on my mac and pushed in 1.1.2 .
The first thing i noticed when i rebooted it was that i had sound again, i tought wow!!, lets try to call 112 (911), and that worked to!!!,
so the next step was goin into the menu seein what modem firmware i had, so i did that and i noticed i had the latest 1.1.2 modem firmware aka "04.02.13_G", with that in mind i went into recovery mode once more and recoverd to 1.1.1 .
After that i jailbroke the phone and veryifed i got 1.1.1. After that usin the apptapp installer, installed "BSD SubSystem", and after that added http://iphone.unlock.no as source, then i downloaded a program called "BB Downgrader (1.1.2)" under their unlocking tools directory in apptapp.
I rann the program, and it worked, it downgraded the modem firmware to 04.01.13_G , so after that i followed the instructions from http://iphone.unlock.no/#how-to-downgrade-1.1.2 and that ment once again restore to 1.1.1, did that, jailbroke it, apptapp install anysim 1.1, and plugged in the new sim and runned the anysim app, and guess what, after 6 weeks with a fucked up iPhone, its WORKIN again,!!!, and to remind everyone once more, my secpack was fucked up beyond recognition, the same with my baseband. so i hope this "long" guide will help others with their troubles. Cheers!
