You where attempting to restore device with resized partitions - it is already wrong. You should use full backup/restore procedure instead. Than you were trying to apply
changed AMR - do you know if system partition has enough space for your additions? Also - there is no need to re-install jailbreak multiple times, once is enough.
Here is what I would do (not sure if it will help): charge the device, use hard reset and try to boot into recovery mode. See if you could open terminal session into device. If successful - you will need to manually restore device partition by partition (use search - there examples here). Or try to restore full backup if you have one... All of that is difficult and dangerous for the device - but I guess you are not afraid
