[Q] I can enable usb debugging!

Hi, i have brick my Nexus 4, is a softbrick. i tried alot of different method to save it, but most of the method need to enable usb debugging, but i cant even load in to screen, how to enable usb debugging???? any ideas guys?

Turn off your phone, then press VOL Down + power. Phone will boot into fastboot mode. From there you can either flash whatever you want or enter stock recovery by browsing the fastboot menu with the volume keys and selecting an option with the power button.

[Q] Bootloop, cant get into fastboot

Hi
I rooted my nexus 10 some months ago. All worked fine until yesterday. I wanted to go back to original firmware and used the WUGs nexus root toolkit to download 4.4.3 version and flash it. But afterwards the tablet doesnt boot anymore. Google logo appears and then the circle thing never goes away. I searched many threads, and all base on going into fastboot and flash again, but thats the problem. I cant get into fastboot. The usual combination (Power and vol+ and vol-) doesnt work! I tried many other combinations with different timings, longer press only vol+ and power ...., I always get to google logo after it vibrates.
Is there any other way to get into the fastboot mode ?
Can I connect it to the computer and interrupt the boot process when I switch it on via the PC?
thanks in advance
regards
Erich

Try to connect it to PC with original usb cable and run "adb devices".
If you see Nexus device, you can try "adb reboot recovery" and upload a ROM to /sdcard with "adb push" for flash it.

Hi
Thanks for your relpy.
But thats the problem, even if I could upload a file with adb, which is not working, how would I flash it if I cant get into fastboot or recovery mode ???
thanks anyway
regards
Erich

I think what patzzz is saying is that it depends on your bootloop, often is the case that when someone is in a bootloop the kernel does initiate and adb is functional. Not always but at times for sure.
So if so you can attempt
adb reboot recovery
Or
adb reboot bootloader
If the above doesn't work than you will have to continue trying to boot to bootloader manually with key presses (which I believe is power on while holding volume down)
Best of luck!

Hi
Thanks for the tip. Unfortunately it doesnt work. It made a batch file which calls adb devices and adb reboot bootloader in a loop, so it can send it to the device if it is found, but the tablet isnt regonized, tried some reboots and no luck, adb cant find it )))-:

It seems a brick, but you can try using fastboot command instead of adb:
Code:
fastboot devices
fastboot reboot-bootloader

I suggest you do a factory reset from the stock. You have gone back to stock firmware so you should have stock recovery. I had this happen once and this work for me.

Hi
I will try it with fastboot too, maybe it works....
How can I do a factory reset without recovery mode ?
thanks

Erich

1.If your tablet is on, turn it off.
2.Press & hold the Power, Volume Up, and Volume Down buttons at the same time for several seconds. You'll see the word "Start" with an arrow drawn around it.
3.Press the Volume Down button twice to highlight Recovery mode.
4.Press the Power button to start Recovery mode. You'll see an image of an Android robot with a red exclamation point and the words "No command."
5.While holding down the Power button, press the Volume Up button.
6.Use the volume buttons to scroll to "Wipe data/factory reset," then press the Power button to select it.
7.Scroll down to "Yes - erase all user data," then press the Power button to select it.

>>2.Press & hold the Power, Volume Up, and Volume Down buttons at the same time for several seconds. You'll see the word "Start" with an arrow drawn around it.
Thats the problem, it doesnt work! Tried it a dozent times, only Google logo appears.....

As soon as the Huawei logo appears release the power key and continue to hold the volume up key until recovery loads. That seems to work for me. Make sure you press the 2 keys at the same time to start.
Do you have stock recovery? or TWRP? and is you phone rooted?
IF you have a rooted phone you can install 'Flashify' or 'TWRP Manager' or 'ROM Toolbox' to boot direct to recovery while phone is on.

With the volume up, it says:
"Your device has been unlocked and can't be trusted....."
Your device is booting now...
And then nothing.
Can't boot. Can only access fastboot.

Reflash your recovery in fastboot.

Hardware button don't work in bootloader?

Hey guys. I just got LG G6 H870 model. Unlocked bootloader without much problems, but issues came later. While being in bootloader I can't do anything, hardware buttons seem to not work. The only way to get out of bootloader is to use "fastboot reboot" command, but that prevents me from getting into custom recovery after flashing it. Only entering download mode works (holding volume up and plugin in usb cable). Non other key combination work until I boot into system.
Can this issue be somehow resolved?

I had similar problem myself with entering recovery more and the reason behind it was that I didn't press the button combo in proper way. what you actually have to do is while you in fastboot mode you press down and hold power button and volume down button. phone reboots after a moment and you should still be holding these keys and when lg logo appears you let go of power button for brief second and then press it back again and then when a prompt on white screen appears just go yes two times and phone shall boot in recovery mode . I had watch a tutorial movie to figure that out. other easy way is just to have adb enabled and reboot it with adb reboot recovery command via USB cable

No, because I had G5 and I know the proper way to do that. Problem is I can hold the power button as long as I live and the phone won't reboot, regardless of pressed combination or power button solo.

and the adb command way ?

Well... Nevermind, turns out vol down button isn't working at all.

still good way around is adb reboot recovery

Can't unlock bootloader

Hi,
I have trouble unlocking my A40. It's 2nd piece I own and the problem is the same.
When I follow the steps from this forum;
Go to Developer Settings and enable "OEM Unlock" option
Power off the device and boot in download mode
In download mode, you will see the long press and volume up option to unlock the bootloader
Unlock the bootloader. That will wipe your device so be sure you made a backup of your data
After bootloader unlock, boot up the phone and make sure it is connected to the internet or it will trigger rmm prenormal
Setup the phone without google account and others
Reboot in download mode and flash the recovery and vbmeta images
Boot to TWRP
Format data in TWRP
Flash the Multidisabler zip
Now you can reboot

I'm stuck at the 3rd point.
I don't see ANY instruction about Volume UP + Power in download mode. Nor FASTBOOT see my device to run actions with it.
What I see is only "Volume down key + power key for more than 7 secs Cancel (restart phone).
And holding Vol UP + Power doesn't do anything.
How to make this work?
Thanks.

You did enable OEM Unlock, correct?
Turn the device completely off, without any cables connected. Keep a USB cable ready that's plugged into your PC.
With the device powered off, hold both Volume buttons, and plug in the USB cable connected to your PC. Do not press Power. You should see a prompt on either a green or blue screen; select the option for Device Unlock Mode.

Finally.
Thank you for making me try for another time
