VCOM driver: Windows 10 can automatically install it. Please make sure that your Windows is logged in with administrator rights and your computer has a working internet connection when first time connecting your phone.

Here's an optional solution to start the flashing process on your UMIDIGI BISON 2021 if the standard method doesn't work.

It's especially useful if your phone is bricked or is stuck in bootloop

1. Connect your phone to USB.

2. Start the flashing process with the Download button in the flasher app.

3. Press and hold the power button of your phone until the flashing process starts (red bar appears at the bottom of the app window), then release it. In this process you have to keep the power button pressed for about 10 seconds.

4. Wait until the flashing process finishes.

Kind request from users:

Please report any kind of new issues you experience after installing this update only if you've already flashed this ROM with SP Flash Tool in Firmware Upgrade mode. In rare cases a FOTA update can cause more or less serious malfunctions but that means only the update process went wrong, not a badly developed ROM. An updated stock ROM, especially related to the basic functions will not cause any new issues but will solve some of the existing ones.

There is bad bug with this firmware. The battery % is not shown correctly. From 100% to about 30-40% it drops very fast, with only 1-2 hours of screen on time. Then from 30-40% to 10% it takes at least 2 hours of screen use, and from 10% until the phone turns off is at least 2 hours maybe even 3 hours.

Please fix this stupid bug with an update. With this firmware you never know how long your battery will last... The battery % show is a complete joke.

Battery life is very short. Please patch!

A menudo me abastezco de esta droga https://espanalibido.com/comprar-kamagra-oral-jelly-online/. es un buen viagra que ayuda con el sexo. Desafortunadamente, es imposible comprarlo sin receta en farmacias regulares. Pero hay una salida. Ordeno general en línea y rápidamente llevo el paquete a casa. Intenta hacer lo mismo.
