Problema cu Vu+ SOLO 4K

Hi,

Problem with;

Vu + SOLO 4K, I installed the image, Black Hole 3.0.5.j

and now I can not install any other image,

I tried with:

openatv

openbh

VTi

original image Vu + SOLO 4K

Troubled with USB stick Fat32, from 1gb to 32gb total 9 pcs.

when rebooting appears the logo of the image you or what image I installed after that move to Black Hole and it stops here,

the only thing that installs and works is: Black Hole

BlackHole, but regardless of the version I install I show all Black Hole 3.0.5.j and load all the old channel configuration, plugin

everything I've installed, if I uninstall a plug-in or skin appears green screen and re-activate and can not eliminate anything nor install,

when installing on lcd from the receiver appears, "update rootfs" but for about 2-3 seconds and reboot, here's the problem? to "update rootfs"

please someone help me how to solve the problem,

thank you very much,

Now, I've managed to install a new image,

I did so,

with 8gb usb stick, fat32 formatted in ubuntu-server,

putty, sudo mkfs.vfat -F 32 / dev / sdb -I

with the receiver,

with: putty RS232-RJ12, stop boot with, Ctrl-C,

init 4

umount /

reboot

I put the stick in the front usb, I pressed the power button, and installed without errors.

"update rootfs" lasted about 1 minute, not 2-3 seconds how to try in advance

image, Blackhole-3.0.5-vusolo4k_usb_release_20180306_17a33d3

update online BlackHole-3.0.5-K, works perfectly

thank you
