3GS - 3.1.3 & 05.12.01 FW , 359.3 iBootroom, Spirit Jailbroken can i unlk/dwngrd?

No 3.1.2 FW on file with Cydia

is it possible in any way for me with the older bootrom to be able to either unlock at this point or downgrade to 3.1.2 (with no 3.1.2 SHSH on file anywhere) and unlock?

currently jailbroken with spirit as of last night. 3.1.3 firmware with 359.3 bootrom.

just checked with fuzzyband and my bootloader is currently 6.04 so it looks like its a no-go at this point?

You cannot unlock at this time with baseband 5.12.01

so even though ive got the older iboot there's no way to downgrade since the bootloader has been updated with 3.1.3?

thx

Your bootloader can't be upgraded it is hardware. Only 3G phones with bootloader 5.08 can downgrade basebands to unlock. 3GS phones cannot do so.

Again, you CANNOT unlock 5.12.01 yet.

yes i figured that one out i tried and it messed up my phone, i just wanna know if there's a way to reverse the procedure... or at least be able to boot the phone

[i.Annie]

You restore the phone through iTunes.

my computer won't recognize the phone tho...

Put it in DFU mode or recovery mode, whichever works for you doesnt matter really. Google it if you dont know how. You will find a nice illustrated guide.
