Hi do you have a nandroid backup of HTC one Tim Italy with cid TIM-401,i don't find it anywhere!
Thats because people dont post nandroid backups as they contain personal information. Your best bet would be to look for a stock RUU for your device.
There should be one on the HTC site. They normally keep a RUU for each model.
A nandroid from someone elses device will cause you more issues then anything as it contains Device files that are unique to each device like IMEI and others.
Not exactly true. It's perfectly safe and acceptable to share a nandroid of /system and /boot partitions, they don't contain any user specific data and can be useful for restoring the system in the absence of an RUU.
Not sure how safe that would be when the system partition contains the Efs folder which controls the IMEI.
