Hello All, If I go through these steps on an older 3GS curently running 3.0.1 with the 4.28.06 baseband, will I be able to restore with a custom firmware if something goes wrong with the phone later on? Basically Id like to know if I can restore my 3GS with a higher custom firmware without the SHSH (or BEC and iBSS) files for that os version. 1) Jailbreak at 3.0 using redsn0w 0.8 3) Create or obtain a hacktivated custom 3.1.2 firmware (pwntool created maybe?). 4) Shift-restore or command-restore to this custom 3.1.2 firmware. Really want to avoid accidentally upgrading my baseband and having apple screw me over if I need to wipe and restore my phone later on. Also if this will work, would anyone do me a huge favor and either point let me know where to find a custom firmware like this (on a PC so cant create it myself) either through PM or whatever? Thanks!
