Try to use JTAG debugger or TTL Converter. It'll help you to upload firmware.

@@aviyansthoughts bro can you tell me what is the exact problem like it is working fine till choosing firmware and then it showing also the port in yellow colour but the loading is not starting ... May be bcz there is no direct reset button on vc02 ... But I tried connecting it through controller like Arduino Uno, esp8266 and also esp32. On every board there are reset options but on all of them it was not starting loading after yellow line is coming after selecting firmware ... What should I do I am trying from 4 to 5 by many ways but it is not working ... Can you tell me exact problem what's going on and also how can I solve it ... I am totally exhausted by trying it in multiple ways ... Please help me 😔

Bro do you know something about this ?

There are some errors on their website, I have faced the same problem too, after 20/30 minutes I refreshed the page and SDK file was ready to download.

There are many types of voices. You can just change it to female-male or cute girl or man with Chinese accent like that, but you can't change it to American English or British English properly.

Unplug the module, after some time plug in it again and try to upload the original firmware file as I showed in the video, follow those steps carefully.

@@aviyansthoughts but facing this problem from 3day I have tried many bootloders also and try to flash it arduino also but anything didn't work

Did you use hummingbird burning tool?

@@aviyansthoughts yes when tries to upload the file on it shows my module and the section get yellow also but the reset button vc02 is not working after when i uploded debug_update instead of release_update

Ek I2C link ka maximum bus length hai about 1 meter at 100 kbaud and 10 meters at 10 kbaud. Yeh length vary v karta hai bus speed aur clock rate Ki upar depend kar k.

Desktop mode on kar k krna hoga fir.

Ap just firmware file ko bana sakte ho mobile pe desktop mode on kar k lekin firmware update k liye apko PC ya laptop ki jarurat padegi.
