  • Xiaomi Yi 4K (A9 + IMX377).

    New Xiaomi Yi II 4K action camera anounced in May 2016. Capable of shooting in [email protected] and fitted with a touch screen. Could be a certain menace for GoPro Hero4, but for the price. Also I hope it will support running autoexec.ash scripts to get the most of it. YiMAX 4k script is ready to be created.

    My sorrowful thoughts on Yi2 before the official market release:
    1. This cam is controlled using LCD touchscreen, which apparently can't be used with the protective case. On the other hand, using Yi2 without the box you're risking to break the display, and if you do so you will not be able to do anything including turning wifi on.
    2. Where the hell are HDMI-out and MIC-in?

              Yi Open API updated to v0.2.

              What comes with the new release are 1) more camera settings, allowing to get/set resolutions, white balance, exposure etc so to give more control to the camera; 2) media management so can browse, download and delete media files stored on the card 3) an iOS version of YI360Demo app.

                Script for enabling WiFi to control Yi 4K camera with broken touch screen.

                Non official Autoexec.sh file to turn on WiFi via a script in the SD card for users who have cracked screens and cannot enable via touchscreen.

                Step1: Copy this version of the autoexec.sh file onto the root of the sdcard
                Step 2: Put the SD card into the Yi4K camera
                Step 3: Switch on the camera
                Step 4: The words Loading should appear on the screen for a few seconds, once it has gone off the screen turn off the camera, do not touch anything else.
                Step 5: remove the SD card from the Yi4K camera
                Step 6: Turn on the Yi4K camera (with no SD card)
                Step 7: the camera will boot, after boot up the wifi icon should appear on the right hand side of the screen and the camera should be broadcasting
                Step 8: Turn off the camera
                Step 9: Put the SD card into the camera, connect the usb cable to the camera and the other end to your PC and turn on, it should connect to your pc as a usb device, alternativey put the micro sd card into a SD card adapter and put it into your PC.
                Step 10: Delete the autoexec.sh file from your SD card
                Step 11: Turn off the camera and remove any cables from the Yi4K or remove the SD adapter and put the micro sd card back in the Yi4K
                Step 12: Turn on the Yi4K and it should boot as normal and should have Wifi auto enabled each time at boot.

                    Hello, can I use the Yi 4K 1.4.31 firmware for my YI 4K plus? How can I reset the cam to factory settings in case of fail (firmware brick)?

                    Is RAW Photo included?
