[Q] I can't get into bootloader/fastboot mode - G2 Q&A, Help & Troubleshooting

I can't get into the bootloader/fastboot mode, is there something wrong?
Note I am now on stock 4.4 (including stock recovery/kernel etc.) but previously i had custom recovery and same error.
- tried rebooting into bootloader from recovery when I had philz and/or TWRP - would just boot into the OS
- tried power + button up (i.e. reverse of booting into recovery) - same, boots into OS
- tried quick boot root app - same, boots into OS
WTF
Not hugely concerned since I could get into recovery lol but why is it I can't get into bootloader/fastboot mode? What if the OS is broken and I need to ADB something?
Note I rooted/TWRP/PHilzed and went custom for awhile, then I made my own zip using below thread and a full kdz and flashed back to stock including recovery/kernel/baseband (I wanted to go back to 100% stock).

Isn't the bootloader locked on the G2? Coming from a Nexus phone, I was also looking for the option but read it wasn't currently possible to unlock it.

I know we're BL locked, I meant fastboot or download mode or whatever the mode is where you can use adb commands and/or fastboot flash recovery recovery.img if I never need to manually fix recovery for example.

You can use ADB by enabling USB debugging in developer options.
Download mode can be enabled by turning the phone off, pushing power+Volume Up and then plugging in your phone to your PC with a USB cable - I've used this twice already to recover from experimenting with recoveries and ROMs (by going back to stock following instructions here: http://www.droidviews.com/how-to-restore-lg-g2-to-stock-firmware/)

also i've found the phone won't boot in to recovery if it's on mains charge (via button combo not adb/in rom apps or APM)

Thanks, the plugging in USB cable is probably the bit I'm missing!
I know I can use ADB with USB debugging, I'm asking the question if I need to recover from softbrick and can't get into OS

Nexus 7 wont boot to recovery via fastboot

So is fastboot the problem or are you trying to boot to recovery through the bootloader. I would use ADB instead of fastboot. But if what you're asking is that you want to boot to recovery from the bootloader, just connect your USB cable to your computer and then select recovery in the bootloader.

Pretty sure it is fastboot... You use the volume rocker to select recovery and hit the power button... It shows the Bootscreen but doesn't go any further than that.
Edit: it says in red FASTBOOT MODE.. When i select recovery it goes tot he google screen (witht he unlock icon) and doesn't go any further than that.

I'm having trouble too. I have it plugged in to my laptop. When I select "Recovery" and press Power, it just reboots, and then boots into Android.
No recovery.
So I'm gonna try TWRP..
i had the same issue this is what i did
download new recovery h**p://goo.im/devs/OpenRecovery/grouper/openrecovery-twrp-2.2.1.4-grouper.img
then in fastboot
fastboot erase recovery
fastboot flash recovery name_of_recovery.img
wait 15 seconds
unplug usb cable
then use volume keys to boot in to recovery
hope this helps
so any solution at the same screen, same problem.

You want to be in the bootloader mode and select recovery. The trick is that to do that, you have to have your Asus USB cable connected to a live usb port when you do it, and it usually works if recovery isn't damaged.
And you can also use Wug's toolkit on the computer, or if you can boot the tablet, you can use goo manager to reboot to recovery, or the Trinity kernel app, or your rom's advanced power menu.
With the USB cable attached from the computer to tablet, here's what I did:
- Went to bootloader
- Did "fastboot erase recovery"
- Did "fastboot flash recovery IMG"
- Then boot to recovery manually from the device itself via volume buttons and Power
Hasn't failed me yet when trying out different recoveries. There was some issue a while back where you had to have the USB cable hooked to your computer and Nexus 7 in order to get to recovery. Not sure if the bug still exists, but it may be worth trying with the cable in.
Also you probably have to have an unlocked bootloader (lock at bottom of Google boot screen).

Thanks for that.
That worked for me
Does the USB port you're plugged into need to be a computer with the fastboot drivers already installed? My unit freezes up in bootloader every time I plug in any live USB cable, whether it's a computer or not. My recovery is fine, but with the bootloader constantly freezing I'm not able to install the N7 drivers on my computer, let alone input any fastboot commands. And no, I don't have access to the computer with the drivers already installed sadly.

a stupid bug.buoght yesterday,rooted and unlocked.downloaded 10 roms,all kernels,and now that i'm ok to begin test i tried without luck to enter recovery from fastboot (i didn't know this fact)but my cable was inserted on pc usb port...and strange it doesn't work.yestrerday via fastboot i flashed twrp recovery that i love and use also on mine gnexs.i'm on stock rom yet,and without "reboot to recovery" option in powermenu.i reflashed twrp,cwm touch (in fastboot manually)then the same but with a rootkit,no luck.i began to think i have a problem in my device and i don't know how to do because it's a secondary bug for assistance i think..and i read this post.don't even tried commands in few posts ago,already did same things an hour ago.i installed quickboot frm playstore and now i can boot on TWRP.use this for today,when i begin to test roms i'll have the powermenu option!
Sad this,i'm a bit anxious of this bug,because i soft brick gnex every 2\3 days,always trying things and stuff,kernel with modifications by me etc,and i often have to go in cwm via devices off and fastboot before...i see that my tab attacched at pc don't enter recovery from fastboot mode..and it's a problem for me.hope someone discover where is this bug and find a workaround\fix fro that.

Paragraphs dude? Or at the very least, proper spacing.
On stock rooted rom, flash latest TWRP recovery. openrecovery-twrp-2.2.2.0-grouper.img
adb reboot bootloader
fastboot flash recovery openrecovery-twrp-2.2.2.0-grouper.img
Then install Rom Toolbox. Use the "Rebooter" to Reboot recovery, and you should have no issues.

I did this and I still can't boot into recovery. The only way I can boot into recovery is if I use the fastboot command. The rom toolbox does not work for me.
similar problem
I have somewhat similar problem. Well, actually the problem is not very uncommon the way it looks, but usual solutions do not work.
Basically I have erased my old rom (rebooted to recovery from aokp menu) and erased my rom. I've tried mounting the device from the recovery mode, but it was not recognised on my PC. I assumed that this was an Win8 issue.
Once I've rebooted, I could no logger boot to recovery (after selecting recovery all I got was google logo). I've thought of flashing recovery via fastboot, but bootloader seams to freeze with usb cable in (no matter the cable) and resetting does not help (the way it helped others). Also I cannot fastboot at that time either as PC (neither win8 nor win7 machine can see the device).
Any ideas would be appreciated.
When the bootloader freezes with the usb cable plugged into a PC, it is a driver issue. Uninstall and reinstall the drivers. I have experienced this on a win7 x64 system.
It isn't a driver issue as the same thing happens when connecting to a charger and not the PC.
It happens on mine as well.
Well it wouldn't crash with wall charger if it was a PC driver issue.
In either case, I've actually figured out what's the problem. It seems that usb connector is not very reliable. If the it usb connection is poor, the bootloader crashes. To avoid this issue you have to bend the cable towards the screen to ensure the proper connection. It load that way just fine.
Edit: or not... probably bending just removed the connection completely...
Edit2: did not figure out what was the problem, but after playing around some more, the phone has popped up in computer manager and I was able to continue from there. After flashing the recovery (twm -> cwm), the bootloader un-froze as well.

[Q] HELP!!!!!!! I may have brick my nexus 7

I'm not new to clockwork recovery, and I have flashed many Roms on my Nexus 7........ today I did a full back up of my latest ROM and I downloaded the latest version of the bug less beast .....I let rom manager do the back up and flash......then there was an error flashing the new rom and an abort and a reboot.......no im stuck on the google screen with the little un-locked lock at the bottom of the screen......if I reboot and go into recovery it just goes back to the google screen and stays there.....any clue as what I should do ??
Search around the forums for solutions.
Use the Wugs toolkit to make your work easier.
It's not bricked its standard procedure you just need to plug it in

To manually enter recovery from the bootloader on devices prior to 4.1.2 (don't know if it was fixed. its a glitch from google in the bootloader) you must have the USB (OEM of course) connected to a USB port on the computer. Then you can boot to bootloader and use the volume buttons to enter recovery. It may take trying a few times, like connect to usb port before powering on, connect to USB port once you're in the bootloader, etc, but that's your only issue unless when you panicked you tried some other solutions.

dude, i'm told you what you need to do, i had erased manually my bootloader,recover,system,data and i was able to restore w/ what i told you it worked w/out any issues
Get fastboot. plug into your computer and do these:
fastboot flash recovery recovery.img (recovery.img is whatever file you have for recovery. IMO, get the newest touch recovery from CWM and have it in the same directory as fastboot)
fastboot reboot-bootloader
From there, leave it PLUGGED IN and get back into recovery. Worked for me.

Power down your device, and power it back on. Just after vibrate press vol - that will take you to fastboot mode.
I have screwed up on every possible way and fastboot saved me every damn time!!!
Just get the timing right , go to fastboot , connect miflash -> flash stock image.

Already tried MiFlash in Fastboot mode, but it doesnt seem to recognize my device, although I'm pretty sure I have the right adb drivers installed on my Windows 10 machine. MAybe I gotta reinstall them, but I'm not sure which are 100 percent right.
Thanks!!

phone bricked? help!

I decided to update my old oneplus 2 to lineageos 15.1 with, but when I tried to flash the file with TWRP, it shows an error. Since the TWRP version I was using was old, I decided to update it first. Keep in mind at this point i had completely wiped my device. So, I downloaded the "twrp-3.2.1-0-kenzo.img" file, as per a youtube video where the dude managed to flash the update successfully, and gave it a go. It showed up as successful. Then i shut the whole device off, and tried to boot back in to recovery to flash the ROM again, but the thing won't boot. It's stuck on this boot screen (with the oneplus logo and 'powered by android' at the bottom), and refuses to go further. I'm stuck in a situation with the phone having no OS, no recovery and the thing won't show up when I connect it to the pc either. Well, the pc makes the 'device connected' notification sound when I plug it in, but nothing shows up on the file explorer or the device manager.
That's my dilemma, please i need help!
Thanks in advance.

You downloaded the KENZO (this is not oneplus2! ) TWRP and flashed it on another phone (oneplus2), just normal that it doesn't work and your phone is messed up.
If you can enter fastboot (vol up and power button to boot) you can rescue your phone:
-enter fastboot (vol up + power, while phone is completely off, u can also hold it until you can see "fastboot" written on the screen)
-connect device to a computer with fastboot installed
-type "fastboot oem unlock" into a terminal/cmd window if there is no error, you are good to go, otherwise your bootloader relocked, use this thread to recover
-if your bootloader is still unlocked, download the ONEPLUS2 TWRP IMG, ALWAYS make sure to only flash the roms, kernels, recoveries or zips for YOUR phone otherwise you can really DESTROY your phone!
-now type into terminal/cmd: "fastboot flash recovery *drag the oneplus2 twrp image into terminal/cmd window* and hit enter
-use vol down + power to reboot phone into recovery and wipe all partitions
-Install a ONEPLUS2 ROM of your choice
If something is not clear, use google, because this is most likely basic stuff you have to know when flashing your phone
I can in fact go to fastboot mode by holding the power+volume up keys. When I the phone to my pc it does show a fastboot device (9597b869 fastboot). What do i do from here?

P.S, i can enter fastboot mode on the phone via power+volume up.

Oh, the link is dead, sry for that. try this one (GDrive links are up and working).

so i managed to get into qualcomm mode, updated the drivers, and ran "MSM8994DownloadTool.exe" in administrator mode. it went as it's outlined in your guide. however, at the end of that process, the phone got stuck in a bootloop (the oneplus logo flashes for a moment and restarts). and can't get into qualcomm mode now, since when i connect the usb to the pc while the phone off, it lights the display (to show that it's charging, i think). any way back from this?

Do you still have TWRP? If yes go to TWRP and shut down the phone there, afterwards you should be able to enter qualcomm mode again.
otherwise you have to try (i think 10s power button will shut the device completely down). You should be able to enter qualcomm mode if the device is fully shut off (your scenario sounds as if the device is not fully shut off when u connect it to the pc).
Just to go sure: You are absolutely sure to have a oneplus2, are you?

Screen/Touch not working, trying to recover data

Hey, I have an XT1563 with an SD card integrated into internal storage (which I'm regretting deeply now). Never unlocked bootloader.
Long story short, the screen fried and now won't turn on. Now I'm on a long journey trying to recover the data from it.
I'm also a noob at all of this, here's what I've done so far:
I have the Motorola drivers installed, and just the SDK platform-tools installed.
I can't remember if I kept USB debugging enabled or not, but I figured if I could get it into recovery mode I could enable it through that.
But I can't enter recovery mode. The only thing I'm successfully able to do is enter fastboot mode. I tried doing a flash recovery but of course since bootloader is locked it failed.
So from fastboot, since I can't see the screen, I can only guess at which buttons lead to recovery mode. From images, recovery mode is second on the list, right?
I've tried Vol Down + Vol Up. Didn't work. Also tried Vol Down + Pwr. Also didn't work. Fastboot still says it's in fastboot mode and adb doesn't recognise anything.
The only way my laptop is recognizing the phone is through fastboot. When I plug it in normally it doesn't connect (guessing it jumps into charging mode, but adb still doesn't recognise it)
Can somebody help me here? IIRC Moto X Play does have a built-in recovery mode, right? Is there a way to enter recovery mode through CMD/fastboot functions, or can anyone help me with the hardware buttons to reach it?

I'm not sure what is possible. My idea would be:
1. Enter fastboot
2. Fastboot boot twrp
3. Use integrated adb of twrp to access data and shell as well as adb backup. Transfer data using data exchange for Android should also be possible.
