I've posted a query in the main Sony thread, but thought it may be more appropriate here, including more details.

Does anyone know if it is possible to reinstall (roll back) the T3 firmware or even to force a reinstall of the latest in case it is a bug. Was there never an after-market version of the firmware?

I have a battery life problem which is not the battery, replaced with new and tested both new and original on an Imax digital charger. Both show full capacity on several charge and discharge cycles so the problem is in the reader somewhere.

The problem appeared around the time of the last firmware update, (1.1.01.17210). The battery self discharging in a couple of days even when fully, completely, shut down.

I've tried all the obvious, reformat, WiFi off / forgotten, reset, full factory reset, etc. left it battery disconnected overnight.

I see the Sony website no longer lists the T3 in the support pages, though all other earlier models are there.

Sony have been as helpful as always - i.e. Not at all.

Thanks on bended knee to anyone with a solution.
