After a long night finally it worked again

first i have iphone 4 jailbroken on 5.01 with a custom FW BB 4.10.01
yesterday i just respring my phone and it was the last spring for it
the apple logo appeared and no more respons .. i tried every thing starting from booting using redsn0w then trying to re jailbreak and then i tried to restore using my custom FW and tinyamb as usual
all efforts was nothing for 9 hours no good news
i tried to downgrade to 4.3.5 and 4.3.3 it workes but not with 5.0.1
i even downloaded the new 5.1 and make a custom FW and installing it but it failed with TinyAmb but after i quit TinyAmb and trying again it worked fine
i assumed that there is something wrong is going when iTunes requesting blobs for FW 5.x using TinyAmb
today i used redsn0w to make a custom FM using blob stitch option and trying again ...... finally it worked great and i managed to restore my iphone bakck to 5.0.1
i just want to share my long night experience with u all may someone can use of it
thanks,
