Good morning got this from my seller. Hope it helps someone.

I have an S4.

hello friends hizpo has sent me update for s8

I'd suggest you have it upgraded to the latest version first, check it out pls: Method: 1. Download the compressed files from the cloud drive. 2. Decompress, and copy the <upgrade.zip> <MCU.bin> files into a FORMATTED flash drive. Make sure the files are copied into the ROOT directory of the flash drive. 3. Have the flash drive connected to the main device through the USB cable, then click "Settings" -- “General”-- "System Upgrade", and select the <update.zip>, and the system will automatically proceed with the upgrade. (It will take around 6min to finish.) 4. Click "Settings" -- "General" -- "MCU Upgrade" -- select the <MCU.bin> -- Confirm, and it will take around 1min to finish. Please Note: > Do not cut off the power supply during the upgrade, and do not modify the file extension in case of leading the unsuccessful upgrade; If the system pops out the notification that the version of the MCU is incorrect, get access to the factory settings and type the code 774411, then get back and proceed with step 4 one more time. > The Weather app would also require to activate after the upgrade. Please set the WiFi SSID of your smartphone as FYQP5QRG, and then have it connected with the WiFi of the device, this will activate the apk of the weather app. >After the upgrade, you will need to set the correct CANBUS protocol if your car has a CANBUS system, please follow the steps settings-factory-8888 ok-car model The system firmware link： https://jitufirmwarecarletter230207.oss-eu-central-1.aliyuncs.com/update.zip The download link to the MCU upgrade : https://jitu321077708mcu230207.oss-cn-hangzhou.aliyuncs.com/mcu.bin
