Downgrade wifi on TC55 from android version 4.4.3 to android version 4.1.2

Hello and sorry for my english,

 

In my company have three TC55 devices to test a new device for a new android application. In one of these TC55, upgrade the android version to 4.4.3 and we have problems with the wifi. We installed the wifi package for the android version 4.4.3 and the wifi now are ok.

 

Now we need downgrade the android version to 4.1.2 and the OS is ok, but the wifi now have a bug, my question is, does exist the same wifi package for the android version 4.1.2?

 

Thanks.

Hi Radim it's only possible

Hi Radim

it's only possible via Zebra Tech center and only if the TC55 has JB installed from factory (afaik)

Hi,Before you try downgrading

Hi,

Before you try downgrading the device FW - could you please elaborate a bit more what sort of wifi issues are you having?

Going backwards most likely wont do you any good at all.
