[Question] Can't flash, can't get into bootloader...

[aus9]

at the risk of offending mirandam

Also, when I'm in ADB console, when I type any command besides adb sideload or adb devices, I get error saying: "error: closed". I cant get into fastboot with adb console.

this does not look right at all.

If you have a PC and adb is running correctly, for Windows users that means in admin mode.....you can not issue any adb command until you see a positive result for

Code:

adb devices

if you phone appears then and only then can you run

Code:

adb reboot bootloader

this will reboot phone into either a menu bootloader or fastboot

2) if you are in fastboot.....all adb commands MUST fail
instead you need fastboot installed on your PC and you now issue

Code:

fastboot devices

Do you see a trend here? and you must see a device

AFAIK your options to flash during fastboot are limited to
boot,recovery and system....choose one or more or all

Pretending your recovery is crap you would restore your original with

Code:

fastboot flash recovery recovery.img

where recovery.img is in the same folder as a windows user is running fastboot.

Linux users have better options but would require even more reading that your time does not seem to permit.

3) custom recovery offers sideload

to get to it....you boot into recovery
choose install zip
choose from sideload

on PC your command is

Code:

adb sideload filename

where filename is in same folder as a Windows users running adb.

another way of putting that is
---while in adb mode you are never in fastboot mode
---while in fastboot mode you are never in adb mode

good luck
