So if I want to unlock the bootloader on day 1, I just have to boot into fastboot mode, plug into my computer, start adb, and then run "fastboot oem unlock"? I've never had a nexus before so I'm not sure if this is the right procedure.
Not quite. Previously this would have been the case but now you have to boot the phone first. You can skip all of the configuration stuff because all you need to do is get into Developer Settings and flip the Enable OEM Unlock toggle. Then you can reboot into bootloader and run fastboot oem unlock. This is of course assuming that you have the correct drivers in Windows or the correct package in Linux.
I was just wonderin i got a fastboot cable comin in in a week for my kindle hdx. To twrp and root it. Just wonderin if anybodies tried one on the g4 yet
Android does not require a special cable to enter fastboot.
I've personally never heard of anything called a fastboot cable, a quick google search shows a kindle factory cable... obviously amazon have done something to prevent fastboot over a standard microusb.
Fastboot on G4 is easy to access by enabling OEM Unlock in the developer options and then rebooting into the bootloader. Doing anthing with fastboot however depends on the unlock status of your bootloader. A Locked bootloader will simply reject any useful fastboot commands.

There's a particular dongle that you plug in to the MicroUSB socket and when you turn on the phone it's supposed to boot straight into fastboot mode.
Not sure whether these boot the G4 into Fastboot mode - being able to boot straight into fastboot without having an OS installed would be a real boon.
Does the device not already boot straight to the bootloader when there is no OS installed. i would have thought the boot process would get stuck in the bootloader with no OS.

A fastboot cable has a wire grounded out and commands fastboot. kindle uses them and a few other comps used them too
Im just testing stuff out.

Bootloader mode - yes. Fastboot mode - no.
Bootloader allows you to flash stock KDZ or TOT files, fastboot allows you to install custom recoveries, modems, kernels, ROM's from ZIP or IMG.
A chain of unfortunate(or reckless) events led to my soft bricked Robin. This is the current state of the device:
Does not boot normally, stuck at boot loop.
Have access to fastboot mode and Stock recovery.
No access to adb.
Device is OEM Locked and does not allow flashing anything from Fastboot.
What are my options? I have seen posts for other devices where they toggle OEM Lock status from Fastboot
Also some other cases where they use QFIL to flash stock OS.
Please advise.
Can unlock the boot loader with
Code:
fastboot -i 0x2c3f oem unlock
Did you get the drivers n stuff?
(apologies if you know all that).
I bought a refurbished Razer phone one from the official razer eBay page, and it's stuck on download mode. I haven't tried flashing anything, I haven't even ever been to the home screen. What can I do to fix this?
Get the Google USB Driver and make sure your Razer phone is installed with these drivers
https://developer.android.com/studio/run/win-usb
Get Android SDK Platform Tools for latest ADB and fastboot tool
https://developer.android.com/studio/releases/platform-tools
Open command prompt to that folder and run these commands
fastboot flashing unlock
fastboot flashing unlock_critical
fastboot set_active a
from what i've gathered from other threads with similar problems, that's the jist of it...
It says "Waiting for any device" the problem is that it's not recognized by the computer.
Thank you ! Same problem. This is halp! after first run, works. Question, can I block it now? and how please... fastboot flashashing lock ?
Now I can block back? fastboot flashashing lock ?

Hello. Same problem. ( I bought a refurbished Razer phone one from the official razer eBay page, and it's stuck on download mode. I haven't tried flashing anything). It helped me. Now I can block back? fastboot flashashing lock ? Please, sorry my english...
EDIT: The links did not copy paste appropriately. I fixed them now.
These are all posts from various places in this thread:

"Find the driver here:
https://dl-ssl.google.com/android/repository/latest_usb_driver_windows.zip
unzip the files/folder to a location you will remember
Follow the instructions below, point the windows driver update to the .inf file in that folder then driver will install. Make sure you have the latest Android platform tools, the link is also in the PDF below.
https://s3.amazonaws.com/cheryl-fac...stall_Android_Fastboot_Drivers_on_Windows.pdf
open a command prompt from within the Android sdk folder while the phone is still in download mode (phone stays and reboots to download mode through each process below making the process fairly easy)
type: fastboot devices
your phone should show up once drivers are installed correctly
type: fastboot flashing unlock
use the phone vol + - and power to select yes
phone should stay in download mode
type: fastboot flashing unlock_critical
use vol + - and power to select yes
phone should stay in download mode
Download the firmware image below or if you want to try the following command type: fastboot set_active a && fastboot reboot
to see if the phone boots, not sure if all the phones have Android installed. One poster below seems to and also seems to have his bootloader unlocked. This won't be the case for everyone. If phone does not boot continue downloading the firmware to install it
https://s3.amazonaws.com/cheryl-factory-images/cheryl-o-global-6033.zip
unzip all the files and put them in the android sdk folder, from the same command prompt if you're on Windows
type: flash_all.bat
For Mac type: flash_all.sh
Will take a few minutes but firmware will install. These instructions are for RFD members that do not either 1) want the hassle of RMA or 2) take a chance at voiding the warranty (any phone flashing via adb is frowned upon by Razer)"
------------------------------------------------------------
"Yes. Reverse the locking procedure. Put phone back into Download mode (from power off, press and hold Vol up and then plug phone into computer) then issue fastboot commands to lock boatloader starting with critical."
------------------------------------------------------------
"if you have a ryzen pc and getting some error while unlocking... dont plug the phone in at the beginning... type the command when it says [waiting for device] then plug it in ... also dont forget to unlock critical right after"
Now I can block back? fastboot flashashing lock ?

it helped, now it is loaded; but after each reboot it writes, the phone is unlocked and that it is unsafe. can it be blocked back, is it safe that everything continues to work? please write what commands to enter?

Repeat the unlock commands using lock instead of unlock but in reverse order so:
fastboot flashing lock_critical
fastboot flashing lock
again you must place the phone in download mode (powered off...hold volume down key down...plug in) between each command and follow the onscreen instructions.

I used to enter these commands , the instructions were only after 1
I did not turn off the phone and the question on the screen was only after the first command. I probably entered only 1 command <if it was necessary to disconnect phone? ... thank you for help.
Sudo.
If ur using linux - run it with sudo. always run fastboot with sudo
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot set_active a
error: Device does not support slots
Dear All,
I decided to return to stock rom. However, when I type fastboot oem lock, the device cannot restart. Then I tried to flash stock rom again (in bootloader locked state) but it failed....
Any solutions?
I'm having a similar issue I guess. I have the drivers. I can get into fastboot mode but when I type fastboot flashing lock or fastboot oem lock, the phone just waits and I have to volume down and power to restart. Maybe something wrong with phone?
