UMIDIGI Crystal V1.1_20171023 ROM - SPFT + OTA release

kostolany90

I write fastboot flashing unlock. This is the complete code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flashing unlock
...
(bootloader) Start unlock flow

FAILED (remote:
Unlock operation is not allowed
)
finished. total time: 5.100s

If I write fastboot flash unlock, I get an error, that I did not select a partition.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash unlock
unknown partition 'unlock'
error: cannot determine image filename for 'unlock'

Try fastboot OEM unlock or fastboot getvar unlocked

...
(bootloader) unlock_ability = 0
OKAY [  0.009s]
finished. total time: 0.011s

I am also not able to flash the system.img file, it says not allowed in this state

Hello,
It's been two weeks since I received my Umidigi Crystal 4GB-64GB. I have only one big problem with it. The bluetooth is the most horrible bluetooth I've had. With my Bluetooth headset, the connection stops almost when I put the phone in my jacket pocket. I have to keep the phone in my hand for it to work. If I go further than 4 meters, it's dead. As I do a lot of cycling, I can not listen to music anymore. My headset works great with my other phones. I am in Android version 7 and I have the last ROM.
Thank you for telling me if I am the only one with this problem, and if I have to return the phone? And who to send it back?

i'm italian sorry my english.
in the next firmware it would be better to fix:
1) wi-fi and LTE radio sections do not work well, weak signals
2) gps is not good, weak signal
3) Replace calendar app with a more recent and functional one
4) Replace clock app, the alarm often does not sound at preset time
5) give the opportunity for users to uninstall apps included in the firmware that does not
     use, or at least deactivate them

thank you so much

Grazie mille per il consiglio già fatto, ma non siamo noi che dobbiamo risolvere i problemi ad Umidigi è lei che dovrà farlo con una nuova rom che non abbia tutti questi problemi peraltro non risolti completamente nemmeno dopo il rilascio dell'ultimo firmware...e perchè no magari Oreo......
