U4 Firmware uograde problems

I (think) I have upgraded the firmware for U4

Unsure, as the details do not show similarities to data I expected.

However, the results are a disaster.

When scrolling through the EPG lists (upcoming TV programmes to select to record) the U4 seems to run out of memory - when scrolling forward the selection sometimes goes forward, sometimes goes backwards, sometimes changes the selected channel.

Selected programmes to record sometimes revert to being not-selected.

It appears I am unable to scrap this upgrade and revert to the earlier version.

The firmware version is shown against the "Revision" label in MENU>>Information>>About.
What's shown there?

Did you do an online firmware update or a USB firmware flash?
Perhaps you should perform a USB update. The full USB firmware image of 20211010 can be retrieved from this topic "Current firmware - 19.3_20211010"

Rolling back isn't the best option here. These symptoms sound unique to you, so something sounds like it has gone wrong with your update.

The best bet is to re-apply the update using the USB method as Grumpy Geoff mentioned. A USB installation is essentially a fresh start from a known and proven working copy, so if anything goes wrong after a successful USB installation, then it means either your U4 is faulty, or, if you restored your old settings, then there was something wrong with those.

Thank you for your response. I have only done USB upgrades in this circumstance, however I an mow unsure of what version is installed.

I used to be able to find the Firmware version, but cannot. Can you give me instruction on where in the Menu Set-up I should look?
I am seeing Release 19.3, Build 2021 1010.
Is this what I need?
cheers
