Device model :IPC-HDW4631C-AWhat is your device model & onboard firmware version?
I have a modded IPC-HDW4433C-A camera which had some issues restarting on its own from the very beginning. ........
Am I doing anything wrong?
Or, do I need to try to make different bin file?
Anybody? Please help advising with the step to convert the EOS camera to English version.

Update2:
I used the Mod Tool to extract the original DH_IPC-HX4XXX-Eos_Chn_PN_Stream3_V2.680.0000000.41.R.181212.bin file and -re-build it without doing any changes. Even after that it failed to download the "re-built" firmware using TFTP.
It seems that the firmware signature - is what causing the problem.
Any ideas on how to overcome the signature issue?
How or where this fuction can be seen or loaded?The method to overcome the signature may be founded by analyzing the UBOOT_commonSwRsaVerify function.

System version:v2.800.0000005.0.R
That may have damaged the serial TTL interface on the camera.I tried different serial adapters: one FTDI USB to RS232
Try to reverse the bootloader file and analysis the algorithm in the UBOOT_commonSwRsaVerify function.The serial interface is still OK.
I switched from PC to RPi. Now I don't see gibberish anymore. However when trying to send files over TFTP I'm getting the following message after sending completion: " ER0002:The IMG header be changed!"

Any ideas?
Thank you.
How do I get to see the function?Try to reverse the bootloader file and analysis the algorithm in the UBOOT_commonSwRsaVerify function.

Now I have established connection between UART device (RPi) and the Camera. But I can't update (downgrade) the Chinese firmware back to English. Is that it? With the new signed firmware there would be no way to apply changes?You need USB to UART (serial 3.3v levels). RS232 is wrong!
