2.4.20 <--> 2.4.27 backup


Mar 29, 2012
Becuase of the network error in 2.4.27 i needed to go back to 2.4.20 (2.4.18).
I took a backup in 2.4.27 and rebooted into 2.4.20 but now it gives a crash every second so wiped the entire phone inside recovery and it worked the error dont show anymore. But when i use the backup the error happens again.
Is there something that changed beetween 2.4.20 and 2.4.27 that could cause a backup not to work or crash 2.4.20 beacuse of a complete backup?

in 2.4.20 sms, call log, contacs etc dont get transfered but when you log into 2.4.27 sms call log, contacts etc all get transferred without any problems
