I have been able to unlock various iphones, but none with an involuntary 1.1.1 upgrade. That upgraded from mf 03.14.08_g to mf 04.01.13_g. Then I understood this as an soft brick, or as an expensive itouch. Then appeared many ways to do downgrades (from firmware 1.1.1 to 1.0.2, but no modem firmware included), but still without phone capabilities. The supposed solution is to do a downgrade to the modem firmware that is not easy at all. Considering this issue I read that the solution was to wait for revirginize software or manuals. A couple of days ago I saw a "no" dev team revirginizing guide. It’s not very accurate in the "step by step" at all. Anyway I can easily do the fisrt steps, but when I start downgrading the modem through bbupdater commands error appears. It seems it tries to do them but definitely do not work. I have checked similar people with the same issue and no one has answered their post yet. Another thing I do not understand is why do we have to use ipsf for the revirginization process. So i want to know first if i am correct or not with my iphone technical view. Then and finally what do I need to bring back to real life (phone capabilities) iphones involuntary modem firmware upgraded. Thanks in advance for an answer.

downgrading 1.1.1 to 1.0.2 alone is not enough to drop ur modem firmware. you will still have the 13G firmware, although this doesnt really matter all that much anymore. If you follow the virginizing guide that comes a .DOC file with pictures you'll be fine.
I personally am running a 1.0.2 phone with 13G firmware unlocked by anysim 1.1. I've tried updating to 1.1.1 several times but all have run into errors. personally, if i were you, id' get my 1.0.2 running first

thanks, I went throgh that one too and for as an example of what I consider not a good step to step guide is to try to figure this:
"Now navigate to your /usr/bin folder of your iphone, once done navigate to the folder in your pc where you have the downloaded baseband-flash" I did download that rar file but inside there are the following files, ICE03.14.08_G.eep, ICE03.14.08_G.fls, ieraser, secpack40113, no bbupdater there. This is a small detail, I went and copied from other location the bbupdater and continue till this part perfectly:
"./bbupdater -f *.fls -e *.eep and hit enter", but for my unluck the result is the following:
ProgressUpdated: 100
ProcessDetailUpdated: Sending end-pack.
ProcessOutlineUpdated: Process time was 2 min 3 sec.
Error: Failed to download .FLS: Could not verify downloaded image.

So as you can see even following the pictures there is something I am not doing well or simply something they do not know how to print in a manual. Thanks again.
