How to restore Cydia without SSH

I have a problem with my iPhone 3G (16GB | 3.1.2 firmware | new boot loader). I have my iPhone with black rain and it is jailbreaked and installed the Cydia. That was also quite a good time, but since the latest Cydia crashes directly after starting, starting at "loading new data". Now I have intense internet search operation and found no way to fix Cydia. I have tried the following: OpenSSH was not installed for me and I cannot re-install without Cydia. With iPhone Explorer Diskaid or I am not in the correct folder, because apparently I have no root access. Apparently I need the app afc2add "what it (who would have thought it) only in Cydia. The program ClearCydiaListCache also brought no improvement after a restart. I also tried Cydia in airplane mode to start. But this thing is not helping me out. I am completely baffled at the moment and hope you can help me. iPhone will reset this I guess out of the question there are too many application and settings. I am in need of help and need suggestions from your side.

Well before providing you any solution for the problem that you are facing I need to know some information from you side. Have you installed the iFile or not, because if you have installed the iFile then it can install the debian packages and you just need to invite the afc2add, openssh, cydia and what you need just the way down. Installation would be more appropriate and the applications are all installed again I mean to say that if you have lost your iTunes then you can restore it automatically. Just let me know the information that I have asked for, so that I can provide you a better solution for the problem that you are facing.

I think that you should be aware of the risk that you are going to face at the time of doing jailbreak. As far as I know the new Linux installation are not quite large for the recovery purpose. One more thing with 3g everything is not so good hence there too many chances of facing problem. Without using openssh it is really difficult to install the program and the other problem is that without cydia it is really hard to install OpenSSH. Hence you will require a program that can solve the exact situation that you are facing; I mean to say the exact problem that you are facing.

Thank you for replying so generously but the problem is that I am not having iFile, I mean to say that iFile is not installed in on my iphone 3g. I think I am in really big problem because I am not having iFile and also not having SSH. So I am going to repeat my question that is how to install Cydiya without SSH and iFile. Is there anyone who is having a solution for this problem, or it will be better to say a better solution for this problem. I will be waiting for your reply or I should say that I will be waiting for your related reply.
