Hi Dejay,

There are many E2 Images for the Icecrypt S3700.
The E2 Images have many different configurations and none are perfect. All E2 Images for all machines have issues somewhere.
The most common cause for S3700 with UK E2 images crashing is that they are normally configured to use an external memory device(usb stick) for storage of the auto download of the crossepg data.
If the image you have installed has this set up and you dont use an external memory device then it will be storing the EPG downloads into the internal flash. This will quickly buffer up and crash the receiver.
You will need to either set up the USB storage for the epg data or disable the auto downloading on the crossepg.

I've never found a perfect E2 Image for any Linux receiver no matter what chipset or manufacturer.
Some Images on some models are very good but none perfect and all become unstable if the wrong addon, plugin is installed, or an incorrect configuration is used.
That is why E2 images are constantly changing and developing, not always for the better either.
You need to find the one that does the job for you, or you like the extra features it has pre-loaded or the way it does them.
Better still is to learn how to modify the stock generic image release from the coding team such as HDMU, Openpli, PKteam and make your your own version with your own addon's. The S3700 is known as ST7162 triple tuner when looking for E2 images.
