    P3 Firmware tips and tricks of phantom 3 family transmitters GL300A and GL300B

    AC version 1.8.0, RC 1.9.2 is working. Motors arm. Still have the encryption error shown in the app. Not sure if that is going to go away once it shows up. Not sure how to proceed to role down to 1.7.6 AC /1.5.8. RC

    P3 Firmware tips and tricks of phantom 3 family transmitters GL300A and GL300B

    Sounds like a plan. On version at a time until the AC links with the RC without the errors that prevent arming. If I'm successful, how do you suggest I come back to the desired 1.7.6 (AC) and 1.5.8 (RC)?

    P3 Firmware tips and tricks of phantom 3 family transmitters GL300A and GL300B

    Not sure if I understand completely. Lets say I start from scratch and get the AC back to 1.11.2 and the RC at 1.9.2 . Assuming all is good (but I doubt it at this point), I would then walk the AC down one version at a time and check the connection to the RC. At what point and what RC version...

    P3 Firmware tips and tricks of phantom 3 family transmitters GL300A and GL300B

    I keep digging and need another life line. With the AC at 1.7.6 (without the "+"), I attempted to role back the GL300B to 1.5.8. Android DJI Go 2.4.2 was uninstalled as it was not giving me options to upgrade/downgrade the RC (long press the grad cap). The DJI-Go 3.159 was installed and the...

    Fix no video feed / black screen / no image transmission / no FPV on Ph3 Pro

    Yes, I understand the mismatch. My intention was to downgrade the gl300b to match the AC. I was under the impression this was possible as I see others have accomplished it.

    P3 Firmware tips and tricks of phantom 3 family transmitters GL300A and GL300B

    My goal was to use older firmware on both the RC and AC. I see others have been successful with that. My plan was to walk the AC down one version at a time using the Debug file and then downgrade the RC to be compatible. I was successful in downgrading the AC. I assumed downgrading the RC...

    P3 Firmware tips and tricks of phantom 3 family transmitters GL300A and GL300B

    I have similar post on other threads, but have yet to figure out the current downgrading process for a gl300b with the latest firmware v. 1.9.2. The long press procedure pulls up an update screen on the Android app with a blank pull down screen. Nothing to download. I have put the C1-FW .bin...

    Downgrading RC firmware.

    Old thread but I see recent activity. Struggling with downgrading the RC. Will the usb wipe.bin file work on a gl300b? If not are there any downgrade options for the 300b.?

    That is a great write up for r the gl300A. Still confused about downgrading method for the gl300b as it was indicated the usb method will not work on that model

    Fix no video feed / black screen / no image transmission / no FPV on Ph3 Pro

    Can't figure out how to downgrade a gl300b. I have done the debug process with the bird, now trying the controller. Placed the "C1 xx" file on a usb drive, inserted, turned the controller on - nothing happens. Must be doing something wrong but can figure it out I tried the special button...

    Fix no video feed / black screen / no image transmission / no FPV on Ph3 Pro

    If I understand correctly the same firmware bin packages used for the AC work on the RC, correct? Additionally do the same debug file use to downgrade the firmware on the AC work on the RC? If I want to use 1.07 or 1.06 on the AC, what is the suggested best version for the RC.

    Fix no video feed / black screen / no image transmission / no FPV on Ph3 Pro

    I have made some progress, thought I would share As for the gimbal with no video transmission, I ended up fixing it by removing the cmos module from the camera. I believe resetting this cable did the trick. Years ago I monkied around with this component removing the IR filter from the lens. I...

    Fix no video feed / black screen / no image transmission / no FPV on Ph3 Pro

    Thanks again. I wish I had the will to drop it and move on. I suppose the puzzle is a needed life distraction. The putty log was generated from a disconnect gimbal top board. I will attempt to connect everything and get a new log in hopes to discover more clues. I also question if my...

    Fix no video feed / black screen / no image transmission / no FPV on Ph3 Pro

    Still plugging along. I was able to flash the uImage and verify the primary kernel is booting (putty file attached). However, I still have the same issues. No transmitted image, blinking green led, can't complete a firmware update. I also notice it takes longer to shut the bird down after...
