Safe mode

Hi, first I'm headed into work so I don't have much time to do some searching till I get home tonight, so I thaught I'd shoot off a quick thread about my issue.

So I've had my phone jb with pt on 3.1 fo awhile now in the last 6 month
I'm guessing it's crashed and entered safe mode maybe 1-2. Till today it's crashed 3 times in about 5 hours. Now the only thing I've added in the last few weeks is the android unlock and a payed add on to catagories that allows badges and such from apps in folders to show up ontop of said folders.

So I was wondering if anyone had any advice, or could point me to some info that might help me debug this issue without a clean restore

I'd rather not restore because I tried to jb a friends phone with the custom 3.1 fw I have and I jut kept getting a 1600 error. So I'm afraid if I try to restore mine I'll lose my jb. Thanks, niyao

 

Ohh and I forgot to add that when it enters safe mode it says moblie substraite /did not/ cause the error

 

So can a 3g be restored to any older fw without any added steps? It's just the 3gs that looks to apples server to allow only the newest fw to be installed?

I ask because when I tried to use the custom fw 3.1 that I used on my Phone on my buddies phone and got the 1600 error, I tried all my USB port restarted my pc ect to get it to load and i just kept getting that 1600 error.

That's why I'm hesitant to try a full restore on mine.

 

Ok think, ive done my homework here, but I would like to double check this.

being as I still have a copy of the custom 3.1 FW I used the first time, I would just go into DFU mode again and shift restore and select that FW again just like I did the first time? Not have to restore to an offical version first?

and correct me if I am wrong but if I go into DFU mode and get the 1600 error, a hard reset should put the phone back to how it was before going into DFU correct?

thanks
