Hello all,

I am not italien, so i dont what there says, so i use translator.
But what must i do to install the cuoco92 rom?

Because when i download the rom and place it on my smartphone and want to install it trough standard recovery, i get an error message: E: failed to veriefy whole-file signature E: signature vertification failed installation aborted.

So there is something go wrong, i dont have TWRP yet, because in the first post even if i translate it i cant understand the message.

Can somebody help me out with installing this?
How to twrp my nubia z9 mini,

What have i done so far?

1. created a folder called TWRP
2. created a folder in TWRP called theme
3. Downloaded a theme from TWRP project and place it in the map theme (ui.zip)

4. downloaded the Recovery_TWRP and put it in a map called test on my pc
5. trough cmd did go to the map trough cd users\my name\desktop\test
6. i did turn off my phone, and set it in fastboot
7. with the command in cmd: fastboot -i 0x19d2 flash recovery Recovery_TWRP.img i pressed, and get this error:
''Fastboot'' is not reconized as an internal or external command, operable program or batch file.

What am i doing wrong???

Hi, first of all you have to install drivers and fastboot/adb tools from the second post
After you have installed them, you have to connect your smartphone to PC and let the PC recognize the cell. After the drivers are been installed you have to reboot into fastboot mode (from Settings -> About phone -> System update -> Fastboot and then confirm the warning message).

When you are in fastboot mode, PC will install again another kind of driver (if not you haven't installed the driver I told before) you can type the command you have said in your post.

great did install now the adb tool , did not do this before.
Uhm now i am in fastboot mode with the phone connected to the pc but the pc dident install anykind of driver.
I think i have installed already drivers for the ZTE NUBIA Z9 before for other roms, so now again when i am in cmd and want to run fastboot -i 0x19d2 flash recovery Recovery_TWRP.img i get the same message as before.

Have debugging on, did everything you told, but stuck at this point: fastboot -i 0x19d2 flash recovery Recovery_TWRP.img

Close every Command Prompt you have opened and then install again ADB/Fastboot tools... when installing tools you have to press Y to every question it asks...
After everything is installed, open a Command Prompt and type the command fastboot if it shows this is correctly installed:

You have simply to select the option "reboot to recovery mode" on fastboot menu.

mi trovo ancora nella situazione waiting for device

Sottolineo che sono nella cartella della recovery ed è da li che lancio il comando :fastboot -i 0x19d2 flash recovery Recovery_TWRP.img
Come da guida nella prima pagina.

Il telefono è acceso e collegato con debug attivo...

Quello è il comando per cellulare spento ed in modalità bootloader...

@INNOR hai installato i driver del dispositivo? Lancia il comando e mentre sei in attesa del device, premi vol + (+) power per entrare in bootloader, poi collega il cavo usb al telefono

[theduke1989]

thanks, my phone did go to the twrp in my theme, but after rebooting again for twrp, it is in chinese (yirom.com things.).
do i must do this everytime with cmd or ????

my phones stucks at the red/white chinees letters, my phone doesen go further than that...
and recovery doesent work eather, the phone when you press vol- and power the phone restarts, but no recovery or fastboot...

Ciao a tutti,

questa mattina mi è arrivato il telefono, l'ho già rootato e installato il FW di Cuoco92 (Grazie mille per il lavoro), solo che ora mi dice che trova un aggiornamento disponibile? Inoltre se ci saranno aggiornamenti futuri dalla casa madre come si fà?

Tra l'altro, qualcuno ha sbloccato la banda LTE B20 800Mhz? Io ho Wind per cui niente LTE al momento
