LG flex secure booting error

[Gudasta]

Wana jamvi naomba mnisaidie hili, nina simu yangu lg flex ni mpya sijaitumia, jana kuna option niliichagua ya ku update android ambayo ni os ya hii simu. Ghafla simu ikazima na kila nilipojaribu kuiwasha inaleta ujumbe huu:
ERROR: Boot certification verify
[720]----------------------------------------------------------------
[720]
[720]Secure Booting Error
[720]Cause: Boot certification verify
[720]

Kuna option moja nimeiona online na nimeijaribu ya kusolve hili tatizo lakini sijafanikiwa. Option yenyewe ni hii:



Possible Solution 2: Enter Recovery Mode
If your LG G Flex doesn't work as before, if you are experiencing continuous lagging, screen unresponsiveness, or you even think that your device might have a virus-infection problem, we have another solution for you. In addition to the hard reset that we have just told you bout, you can also try the steps from below for unbricking the handset:

1. Turn off your LG G Flex handset;
2. After waiting a few seconds, press the Volume down and Power buttons until the LG logo appears on the display;
3. Release the Power key for a moment and then press it and hold it again;
4. Keep pressing all the keys until the recovery mode menu is displayed on your LG G Flex;
5. Finally, select ‘Reboot system now' and the procedure will be over

Naomba kama kuna yoyote anayeweza kunisaidia afanye hivyo
