Flex Cable Issues and E250D similarities
The T429 is extremely similar to the SGH-E250 (more specifically the E250D) down to the board color, placement, SoC used, and the flex cable issues from the E250 have also carried over to the T429.

The similarities to the E250 are also evident by the fact that the "Cellular phone Parts list" has 1 component with a description containing "E250"

Firmware
There are several firmware dumps known of this phone, but since there was only 1 firmware version released to the public, they are all version T429UVHC1.

However, in the T429 service manual, the screenshots where the user demonstrates flashing firmware to the phone, the file is named T429UVGD1.
