Yes, the solutions to your problem exist here on the forum

1. You need to charge up your phone enough for it to boot. There are many threads about that, for example http://talk.maemo.org/showthread.php?t=87709

2. You need to fix the problem that was there in the first place. For that many solutions exist, but it depends on what you want to do how to proceed. You have backups; that is good because always there is the possibility of breaking something.

• You can clean flash the device, and restore your backups. This might be easiest if you do not want to go to open mode.
• You can install open mode kernel and remove the /var/malf file, which allows you to continue much like before, you do not need to restore anything. (you will need to recreate your accounts, however, and you will have the open mode warning on boot but otherwice it's pretty good)
