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).

okkkk thanx....but how to remove tamper flags becos without removing them sc guys can still find that the device is tinkered
can we use this http://nexus5.wonderhowto.com/how-t...odded-nexus-5-back-factory-condition-0151304/
Ok, my nexus 7 this morning had just randomly started to not respond to any touch. I restarted the device by turning it off and on again with the power button, and it stuck at Google logo. I can go into bootloader, but not recovery. If I try to go in to recovery, it gets stuck at Google logo again.
The device is stock, didn't even unlock it. Fastboot devices returns the serial number, fastboot oem unlock pops up the screen if I want to proceed, at which point I click no because I don't want to wipe the drive yet. I've tried Nexus Root Toolkit to boot into temporary custom recovery to make a back up, but doesn't work. NRT live log is as follows

and then times out.
Since i couldn't connect it with my computer with USB debugging on, the drivers might not have installed correctly, although I did try installing the drivers with NRT. Currently my laptop doesn't recognize the device. It does make sound when I connect the device, but it doesn't show up in device manager at all.
Any pointers please?
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.
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?
