[Q] [Problem] Nexus 7 Wi-Fi 3G Cyanogen-Gapps ERROR

Hi guys. Today I unlocked the bootloader of my Nexus 7 Wifi+3G MODEL and I rooted it. All went perfect. Then I installed Clockwork Recovery Mod Touch 6.0.0.6 and I downloaded Cyanogenmod 10.1 for Nexus 7 GSM and Google Apps for android 4.2.2 and Cyanogenmod 10.1. I tried to install CyanoGenMod but it gives me this error:" assert failed getprop "tilapia" ( ro.product.device) (ro.build.product)
(Status 7)
Error in sdcard
Installation aborted "
Then, I tried to install Gapps and the installation went succesfully on. When I try to power on my device it says "Unfortunately, Setup Wizard has stopped" and when I click "OK" it says " Guided Configuration Application crashed" and when I click "OK" again it opens this window. I tried to re-flash Cyanogen but nothing, and my pc doesn't recognize the device, so I can't open the memory of the device and put another version of Cyanogenmod. What can I do?

unbrick Lenovo tab M10 plus (x606x)

Hello everybody,
first of all I'm, sorry for my newbie's awkwardness and for my bad english too...
I'm a linux (Debian) enthusiast and I'd liked to install it on my Lenovo Tab M10 Plus; my choice felt on "Linux Deploy" but it needs a rooted device so, after an internet search for tutorials and tips and a system backup (.adb file saved on PC) I bravely tried with Magisk... and I failed (or I think so).
The tablet start in a never-end booting loop and on the splash screen appears the message
"
Orange State
Your device has been unlocked and can't be trusted
You device will boot in 5 seconds
"
I can access in fastboot mode so I tried to flash a no-rooted (downloaded) boot.img but it didn't works (the flashing process reports OKAY but the device reboot anyway in Orange Status), I tried with the flashall command that reports
"
error: ANDROID_PRODUCT_OUT not set
"
I tried to wipe and flash but it didn't works, I granted the access in some recovery mode and tried to install the .adb backup file from the SD card but the system says :
"
E: signature verification failed
E: error: 21
Installation aborted.
"
I thought to open the backup .adb file for extract the original files (I don't know if it could be done and if it could be useful) but how?
I think someday someone more skilled than me will solve the problem but, waiting for that day... any advice ?
Thanks, anyway.
Cheers, Ste.
Use official Lenovo Rescue and Smart Assistant
