DO NOT INSTALL FIRMWARE V0.22
ONLY USE 0.15
ONLY USE 0.15
F750 Development thread
We can convert our f750 to an f770 without issue and all functions work correctly, so long as you haven't upgraded to a firmware version beyond 0.15
I am in the process of attempting to create a modified firmware, I have successfully dumped the ROM but recompiling it is an issue
Need to find the uboot recovery files for the F750 camera.

Please do not install any firmware versions after 0.15, installing .22 or newer will prevent you from installing F770 firmware files. THERE IS CURRENTLY NO WAY TO REVERT TO 0.15

Do not use the thinkware F750 firmware version .22, there have been some people report issues and have not been able to change or update the firmware. Please only use .15 F750 version, then update to the .02 F770 version.

the PC viewer seems to have a bug where you cant turn off lane departure warnings. collision warnings can be turned off as normal.
All settings can be changed via the mobile app
Its important you don't swap SD cards when making setting changes so always try and use your normal card (ideally the thinkware one)
Fimware versions

Convert your F750 to a F770
Format the Thinkware SD card
Download
http://www.mediafire.com/file/bmsz896vrivxtcv/f770_3_1.00.02.zip
extract the F770-pkg.bin file from the downloaded zip
copy the bin file to the SD card
Rename F770-pkg.bin to F750-pkg.bin
insert SD card and turn on the camera
Update may take a few minuets so DO NOT TURN OFF!
Update your converted F750
Format the Thinkware SD card
Download the firmware from thinkware
extract the contents of the downloaded zip to the root of the SD card (1 file and 2 folders)
Download the camera data for your area
replace the file in the DriveInfo folder on the SD card
insert SD card and turn on the camera
Update may take a few minuets so DO NOT TURN OFF!
I suspect that all firmware updates will work fine after this however in the interest of your own sanity I will test every firmware version and will report below
f770_3_1.00.02 - Initial release firmware - OK
f770_3_1.00.03 - Aug 2016 update - New speed camera functions - OK
f770_3_1.00.06 - Nov 2016 update - Fixed speed camera issues (?) - working, currently in testing
If you cant enable the speed camera data or some of the settings don't appear to change try this:
Download the latest firmware and speed camera data.
Get the thinkware SD card that has been used on your camera (has videos on it) and insert in to your computer
copy the speedcamera data file you downloaded to the "Driveinfo" folder
In the settings folder on the SD card delete setup.cfg
In the settings folder overwrite default.cfg with the version from the downloaded firmware zip file
Make a copy of default.cfg and rename it to setup.cfg
place the F770_pkg.bin you downloaded in to the root of the SD card
insert the SD card in to the camera and turn on, allow it to boot and install updates
using the same SD card insert card in to the computer
Change settings as required in the PC dashcam viewer program
Finally, copy the speedcamera data file you downloaded to the "Driveinfo" folder (yes do it again)
insert card in to camera and it "should" all be working
Does anyone have any useful technical information on this device?
Specifically I'm looking for info on:
Hardware access through UC-E6 port
Dump complete ROM
Unbrick device through UC-E6 port (ELF file?)
I have unpacked a precompiled image from thinkware
we have the following partitions
BST = Bootstrapper
BLD = Bootloader
HAL = Hardware abstraction Layer
PRI = Primary Kernel
SEC
RFS
DSP
LNX
