Dahua VTO2000a with wrong MCU firmware

[fiuzatec]

RioGrande75
Thank you in advance for everything you posted on this forum and for any tips you may have given me. I actually managed to develop developments and techniques on the VTO but in reality I still don't have 100% back. Summary: The problem I have already explained previously. I started with ST-LINK V2 trying to reset the HEX file. I can read and write without any problem on the VTO (The last HEX file I loaded was the one available at General_VTO2000A-MCU_V3.000.0000000.0.R.20181123

Then I explained the problem again and RioGrande75 said to continue searching the forum and I did...many hours later and with the purchase of TTL UART Serial converter I can load the firmware I want with that technique of changing the first byte from DH to PK generate the various files etc etc and following the instructions I managed to gain access to the VTO again.
Current status: I can access the VTO via IP, I can see the VTO on my cell phone via P2P but...... I can't get the ring button to work, nor can I get the door relays to work. From VTH I can get it to detect the VTO via IP but I can't access the VTO image or open the doors. What could be happening?

(Firmware used General_Multi3_VTO2000A_EngItlFreGetDutSpaPor_P_16M_V3.200.0000.0.R.20190221 )

Good News
Not yet installed on outdoor where module DEE1010x is mounted. Till now VTO call VTH, VTH Answer and open door 1. TOmorrow I will install on place to test rs485 module.
Uffff......

PS: I dont know how to solve the connection to the IPC/XVR on port 554. Before all this problems it works fine... any suggestion ?

Now Installed and at work ! Uffff hard job but educational
Now million dollar question.... WHY my VTO change the language for English ?? I login change it to portuguese, but after reboot (it makes reboot after change language) it goes again to English.
Dahua told me.... its old...buy a new one

Can someone guess it ?

What firmware (not MCU!) did you install? Did you install language pack (needed to have portugese)? If yes, what version?

I used the one in your list General_Multi3_VTO2000A_EngItlFreGetDutSpaPor_P_16M_V3.200.0000.0.R.20190221.bin
First flashed with TTL terminal
THen after realive used configtool ->upgrade firmware -> main program -> General_Multi3_VTO2000A_EngItlFreGetDutSpaPor_P_16M_V3.200.0000.0.R.20190221.language

After that login, change language to portuguese, reboot and in portuguese.... for 1 minute.... then back to English.


but after all my problems and when at point of saying " I wish to VTO comes back and English language is the minor of the problems...." .....

Once I thought that the problem could be on small battery on PCB that I suppose it saves all the definitions of setup. But I changed for a new one and still same problem regarding language

I flashed 4.3 firmware but because it’s SIP and VTO is non SIP I thought the problem was about that. But VTO with SIP firmware works with non sip VTH ?
