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?
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.

You need USB to UART (serial 3.3v levels). RS232 is wrong!
