Hmmm,forget from iTunes to restore because from iTunes work via Apple server or Saurik Server (Cydia) via SHSH Blobs,but we need EEPROM to dump from good iPhone 4 with 01.59 Modem Firmware,if some Box like ORT-JTAG,RIFF if can share Pinout in the future will be good for us.

there is no test point on the iphone 4 , boot cannot be patched cause it used RSA signature on it

the only way is using jtag to avoid ( bypass) the bootloader auth, so we can use a jtag ( maybe ) to reflash baseband and maybe ECID on phone

here is the begining , anyone interested and with knowledge about using jtag interface can test and post ideas

Do you need iphone 3gs baseband solution ?

Yes but what tool to use to reflash? and for ECID it's big problem because he is writed by Hot Eletronic Injection method and its very hard.

maybe riff box can do it but the first thing to found is the jtag pins on the board , on the posted photo i show where are the pins but needs to define trst, nrts, tdi, tdo signals and so on

then we can try to read/write baseband on flash chip

procedure step by step

1 itunes check ecid
2 reading sign software latest version
3 restoring

maybe possible making emulator and virtual server with info for itunes sending info with ecid factory unlocked and making path firmware change in editor 4.3.3 with modem 1.59 to change sing 4.3.3 to 5.0.1 and modem 1.59 to modem 4.11 itunes reading all ok and send firmware to restore

It might be possible if ALL JTAG TEAM and DEV-TEAM will join FORCES to make a solutions on hardware since it is possible for JTAG solutions BUT the problem is that we do not know where is the connection for it and the software to be develop is needed

SO GO GO GO ALL JTAG TEAM and DEV-TEAM to Finish this CAT and MOUSE game, that Apple Company played for so many years!
