[Q] NEW TO LG (Spectrum)

Can anyone tell me where to find the fastboot drivers (win7 pro)
and how to enter fastboot mode?
I tried pwr+vol-down and got hard reset menu
pwr+vol-up rebooted to normal OS
adb devices does return
the serial number and
normal functions work
at regular boot mode.
I'd also like to know to reboot into recovery
[I did successfully use adb reboot recovery,
but hoped there was a button push to
enter bootloader or recovery]
adb reboot-bootloader and
adb reboot bootloader both
just reboot to normal OS.
thanks

can you go to fastboot ? hold vol up and turn on your phone if can
download ADB Fastboot n install (google it)
download the windows zenfone 5 driver
download firmware from asus site i use V1.14.40.50 for WW
extract and you get UL-ASUS_T00F-WW-1.14.40.50-user.zip
get fastboot.img, boot.img from the zip and copy to adb folder
rename UL-ASUS_T00F-WW-1.14.40.50-user.zip and move it to adb folder
hold vol up and turn on your phone - should went to fastboot
open cmd and go to adb folder
type the following 2 lines: "fastboot flash fastboot fastboot.img" and "fastboot flash boot boot.img" (look phone screen, should say successfully for both)
go to recovery - wipe data (google zenfone recovery mode - follow the blog guide)

My asuszenfone5 had usb logo lots of time, when i tried to update to kitkat. You need to try several times power+ vol up (1sec after) since the device has a power button unresponsive. Then just follow the tutorial people told you. Get usb drivers from microsoft(on win8 must give program installer compatibility mode on XPSP3 and administrator previleges to install it properly)In my case i would have batery logo/usb logo several times before getting access to boot mode (10 min attempts So keep trying dont give up. Its an excelent phone but with power button unresponsive/. The same thing happens while you try to wake up phone after deepsleep mode.

I tried to follow this, but every time the it finished the sideload, I still get an error which says "assert failed : greater_than_int (getprop("ro.build.date.utc").1392739......, and then the installation got aborted. I can't access the internal memory cuz I believed my phone was bricked and when opening the phone, I was just stuck with the loading screen and not getting through.
Got this problem when I tried to update my phone to kitkat. The installation got stuck at about 30% and tried to reset it and now I have this problem.
I appreciate it if someone will see this and reply to me. Thanks

[Q] How to unlock Lenovo A1000 bootloader?

How to enter into fastboot mode? I am not able to figure out.
Tried - adb reboot bootloader, adb reboot-bootloader, adb reboot fastboot
None of them worked, However "adb reboot recovery" opens it in recovery mode. I have installed Lenovo Le Tools also. Also tried to open it by pressing -
Vol down + Power (opens factory mode)
Vol up + Power (opens recovery mode)
Note - I have learnt that MediaTek devices doesn't have fastboot mode. I am trying to flash Ubuntu Mobile on my tab which first requires "OEM unlock" which can be done in fastboot mode but if it doesn't have fastboot mode then what's the alternative way?
Please help!

OPO can't access fastboot mode

Hi,
I have a problem with my One Plus One. When I open the phone, there is only the "CYANOGEN RECOVERY" screen that appears.
I can access sideloading using the menu but it is not working. I tried to sideload CM12 and it is looping back to the recovery screen
More over, I cannot access fastboot mode. I tried to use adb to reboot the phone in fastboot mode but adb only sees the phone in sideload mode
The Power + vol up combinaison doesn't work...it will come back to the recovery screen
Any idea ?

Are you attempting to boot into fastboot with the cable connected? That's been known to cause issues, so unplug and try again.

Please help me guys
