I used the search function to find an answer to this but no luck.
I am trying to upgrade the factory Android on my VIM3 to the latest version to get touch screen support etc. but after having tried all 4 ways to enter upgrade mode I am stumped. I ran the various tools/burners etc. and followed the instructions but nothing I tried will initiate upgrade mode.
When using the USB upgrade mode should I also connect the VIM3 to 12 volt external power? I’m a bit nervous about doing this as I don’t want to burn the board.
I disconnect USB accessories, otherwise connections required to flash are the HDMI cable and a USB-C to USB-A cable, the VIM3 will take its power from the USB of the PC.
1.) Install the USB Burning Tool on your Windows PC(Linux tools are also available).
2.) Download your desired and appropriate firmware image. The downloaded file will be compressed, extract(Unzip) the file.
3.) Open the USB Burning Tool and load the firmware image you extracted in step two.
4.) Connect the USB-C cable to the VIM3, connect the USB-A end to your PC.
5.) Press the Function button, aka the middle button, 3 times in under two seconds.
You should see something like this…
I did the steps exactly as you described and what I got is the blue LED on the board did three sets of double flashes and then all LED’s want out and no output via HDMI to the screen. The board seemed to be inert. It did boot up properly when I used the power key to re-start it. I don’t think I am getting a connection to the board as my PC does not show any connection to it. I bought new ‘HI QUALITY’ USB-C cable to use with my VIM3 and am wondering if this is the problem…I tried the process you posted with the USB-C cable plugged into every USB port on my PC but no luck. Anyone have any ideas?
Tomorrow I will go out and look for a new USB-C cable to try as I am hoping it is a simple as that.
From the way you describe the LED, you are successfully entering MASKROM mode.
Certainly could be the cable. Some cables don’t have a data function. Also, if your VIM3 is cased, I have heard of situations where the case prevents the cable from fully seating in the port, resulting in a loss of data line connections.
So if I understand this correctly I should connect my VIM3 to my PC using a USB-C cable and upgrade over that. The problem is that my PC does not recognize my VIM3 over the USB-C cable so tomorrow (Monday) I will buy a new USB-C cable to try the upgrade.
I got it to upgrade! The stores are all closed so I went to my storage locker and rooted around until I found a USB-C cable and used it to replace the new one I was using and it worked first time I tried.
I have come to a situation like this, where I am not able to put my board on upgrade mode with all the possible options.
Here is the boot log. UART Log
There is no HDMI Connected and still it shows LCD resolution error.
I have vim2 which enters the upgrade mode fine and I can see it in the burning tool but vim3 is not, I have tried TST method, Power Key method and also Maskrom method.
Still no luck.
