but when i'm updating, im getting this error in update: Problem with communication between Cell phone and PC
Anyone has any suggestions?

make sure you have usb debug mode enabled.
Reinstall drivers. Remove battery from phone then insert it and plug phone to computer with debug mode enabled. Wait for drivers installing.
Then try again update your phone.

If follow that cant fix. Change computer running windows 7 to update ROM.

NV Flash help

I'm getting really frustrated been at this thing for a few hours, I cannot install the naked drivers because Windows 7 says I have the most recent driver. Not having the naked driver has me stopped on the using wheelie to access NV Flash part because I cant get it into APX mode. Ive tried stopping windows from automatically installing drivers but it still installs it whenever I plug in the tablet. Has anyone had this issue that could help?

you're already in the step of booting in APX mode right?
1. Turn off your device and insert USB cable to your device only
2. Hold volume up then plug it to your computer and since you said you stop auto install driver it will now recognize that windows is unable to find driver for APX device and that's where you use the naked driver. after that you can execute the wheelie command and tada you're done!:good:

Disable USB debugging on the device and disconnect it from PC. Install Drivers. Wait until installation is complete. Reboot PC. Enable USB debugging on device and then connect to PC. PC will then install the drivers as required for your device.
Thx ill try this when I get home

try to connect your phone to a different USB port
or install drivers before you connect phone to PC(you can google for drivers)

Bricked Phone USB not recognized by PC

Need help. I was using Miracle Box to flash stock ROM, I don't know how but the phone (Micromax E453) is bricked now. I tried to start phone in Meta Mode (swiched off phone connected to PC by holding volume up button), it worked once, then following some tutorials I uninstalled (and checked, Delete the driver software for this device) MTK USB COM driver under port. Since then phone is not turning on and PC is not recognizing the device. Tired changing the USB cable and even tried it on another laptop, but no go. Kindly share what else I can try. PC has Windows 10 64 bit and MTK preloader vcom driver always has yellow exclamation mark (always installs with error code 10). I have disabled driver signature verificiation.

Did you have USB debugging enabled in the device's system settings before it got bricked? If not, you might not get it to connect via USB and be recognized.

Thank you for your response. Yes, USB debugging was enabled before it got bricked. I was able to successfully see my device when I ran adb -devices command. I was also able to run fastboot commands. Now its completely dead.
