V8X Locked on Green Light On No Remote Control Works

[Eusebio20]

Friends of the Forum

Good Morning

I got stuck in a V8X device, I tried to go back from the Mars bin of September 2 to the last bin identified by the name GTMedia_V8X_Release_V319_20220519.

I used the GTMedia_V7V8 Refresh Tool_V2.2, and I made the cable according to the diagram published in the forum, it made the whole process, when I reboot the deco, it only turns on the green light, the display does not turn on, it does not respond to the remote control, it does not respond to the remote control.

I tried to use the GTMedia_V7V8 Refresh Tool_V2.2 again and it does nothing, it keeps telling me to reset the v8x device.

Use the USB recovery method and it does nothing.

Any help please

Regards

Incorrect COM connection, it may be due to Windows drivers, most cables are for Windows 7

Thanks to my friend Caje for his prompt response, I'm going to try to do it on a PC with Windows 7, this situation happened to me with a PC that has Windows 10 installed, I'll post results later

Cheers

I did the test with a pc with Windwos 7 and it doesn't work, I think the only option I have left is to record the memory of the V8X with a memory recorder, if someone has another idea, please.

Try different USB sticks, as some may not work.

Here are my notes on flash.bin recovery

The GT Media instructions on forced recovery are here.

flash.bin recovery is done like this.

Place a copy of the unpacked software (the .bin file) on a USB stick and rename it "flash.bin"
With the USB in the unit, power on while repeat pressing "Menu" on the remote.
The unit should reload the software.

Also other users say that you must use a USB stick, not a card holder etc and that stick must be 32Gb or under.
Use the rear USB port on units that have two ports.

I have had units that will not recover.
Try using the same software as was in the unit when it crashed, not the new update software.
You must use the correct software, ie that for the V7HD for the V7HD etc, not software for any other freesat units.

Try even older software as the file for flash.bin.

Look at the LED in the USB stick. When the TV shows the message "USB Upgrade, do not turn off" you should see the LED on the USB flash as the file is loaded.
The USB LED should also flash a few times as the unit first powers on and looks at it.
Also users have said to use the rear USB port for this on V8 units.

New information: Users are reporting that naming the file "Flash.bin" with a capital has worked where "flash.bin" has not. This is with the Nova units mostly.

I found that a USB stick with a lot (more than 30+) .bin files on it, my UHD unit would not show the new software file in the menus.
This suggests that having too many .bin files on the USB stick can also be a problem.
I moved most of the file into a folder and it then showed the file.
Keep only one or two files in the main directory.

From the PDF file for the V7 V8.
6. V7 V8 USB forced upgrade：：：
6.1. Connect the power, and press “MENU” continuously with the remote control.
Note: Press the button continuously.
This should read repeatedly"

6.2.Digital tube shows UP9，，，After releasing the MENU button, enter the upgrade mode

Good luck

There have been user that recover their unit after removing the wifi board, or just cut the 5v power to the board.
