I am facing a problem which i have never faced before.
My phone is in Marshmellow and working fine. The problem is when i want to enter fast boot mode. After turning off the phone when i try to press the power button + volume down, the phone vibrates and then nothing happens except a black screen. I can understand the phone is in fastboot mode as its detected by the All in One Tool. But no further movement after that. I have to press Power + volume Up to reboot the phone again to enter my os.
In simple words i cant access the bootloader menu, all i see is a black screen. Can anyone help please?
Can anyone please help me with this?
From a command prompt with the phone booted to the OS, type the following command:
Code:
adb reboot bootloader
Press enter. What happens afterwards, if anything?
nothing happens, i just see a black screen and thats all..
Any one with the similar problem? any solution?

Hey guys, sorry for a new post. I did a search and wasn't totally sure about what i found so i figured i'd start a new post and get some help.
I bought a nexus off a guy for cheap but it was stuck at the fast boot (?) screen
image
the trackball doesnt work so i cant select anything. the only thing i can do is pull the battery out to shut it down. what can i do to fix this phone? I have no idea what to do to an android. I switched yesterday from wm6.5 so you're going to have to explain everything.
thank you!
You search the forums. That's what you do.
Trackball might be effed up. Replace that
That phone is unlocked
You get to that screen by holding down the trackball when you press power. (Like the above poster said)
Make sure the volume buttons or the trackball are not stuck in a pressed state.
I thought to navigate that screen you use the volume button and power button to select. Trackball doesn't work in that menu

thanks for the helpful comments guys. :]
i meant to also add that none of the buttons work either, volume or power button. i tried to flash amonra's recovery thru cmd prompt but i couldnt do much after that. i couldnt get into the adb prompt. it says the device isnt found, although fastboot promt found the device fine. anyway so after i flash the amonra recovery img i can't get into recovery mode. holding the power and vol down button gets me to the hboot (i believe it is?) but again, i cant navigate the menu with any buttons to put it into recovery mode so i'm pretty much stuck here.
and just to clarify, I have done a few searches as i've said and I didnt feel sure enough that the problems mentioned were my problem so that is why I'm asking for help here.
You should not go to any forum and feel bad for posting or have to say over and over that you did a search. There are many people that can do better and some will show up, hopefully with answers that are not painful to someone who has purchased a new phone... cheap. I would flash amon ra which you can do adb without using any of the phone hardware buttons and then see where you are at. There are many posts on installing amon ra and the instructions are also in the offical thread. With any luck you just have a hosed recovery and the flash will get you rolling.
Can you not navigate the fastboot/hboot screen with the volume buttons? If not then you're gonna run into serious problems. Make sure both the volume buttons and trackball are clear. You can clean the trackball by pressing it in with a piece of cloth and pushing it in different directions while pressed in, this should clear most of the junk on it.
You can also clean the volume buttons and power button a little better by removing the battery cover. Good luck bud.
trackball+power -> fastboot mode.
volume+power -> recovery mode. if you see androids on skates you have the stock recovery.
trackball+volume+power held = reboot
Recovery, boot etc can be flashed from fastboot only.
just to clarify, the first thing that pops up when i press just the power button is the fastboot. i dont have to press anything else, just power.
i flashed amonra recovery img while i was on fastboot mode from my computer (cmd i used was fastboot flash recovery recovery-RA-nexus-v1.7.0.1.img) and it was successful.
Then i tried to put it into recovery mode w the command adb shell reboot recovery. It said that the device wasn't connected.
when i input the cmd fastboot devices i see my device connected, but when i input adb devices it says its not connected.
So i figured I'd put it into recovery mode on my phone by pressing volume+power. I get to the hboot screen with the three androids on skateboards (i realize the screen looks the same as fastboot but the selectable options here are different) but the volume buttons, trackball, power buttons don't work so i can't select "recovery" on the phone.
so this is where i'm stuck
It sounds like you have a stuck or f..d up trackball.

I have the same problem has anyone figured out a solution?

You cannot use ADB commands when you are in the bootloader (i.e., fastboot) screen. You need to be booted into the ROM or into the recovery for those commands to work.
What I find difficult to understand is how come your volume buttons work to boot into the bootloader, but don't work once you are there?
Try flashing each partition from a stock FRG33 ROM (from here). Unzip the files, and flash the boot, system and data images using fastboot (e.g., fastboot flash system system.img) and then try to reboot normally.
Hi,
I have my Nexus One stuck in FastBoot screen. Today, my phone worked normally, but trackball don't worked, so I had to reboot phone. But when I rebooted, the phone started in FastBoot screen, and buttons don't work (volume up / down, power, trackball). There are 4 options (bootloader, reboot, reboot bootloader, power down) but I can't choose any because buttons don't work. Before reboot, when phone worked normally except Trackball, the volume and power buttons worked normally, so I don't think that all buttons are crashed.
My phone has HBOOT-0.35.0017, radio version 5.12.00.08. Also has installed a MIUI Spain ROM. I try to reinstall rom but I cannot, because buttons don't work in FastBoot Screen.
Do you have any idea to solve this issue?
Thank you very much
If it starts automatically in fastboot mode, it is most likely that your trackball switch is stuck down, because your phone should start in a generic bootloader and then give you the option to enter fastboot.
Did you spill anything on the phone or accidentally submerse it in anything?
Yes, it seems that trackball is stuck... I will try open the phone and clean trackball from inside...
How do i take out the trackball?
To take the trackball out you'll need to take the nexus one apart for that you can go check out the ifixit tutorial.
Hey guys, did u find a solution for this? I'm having the same problem here!!!! The track ball was my first guess too, but I feel the trackball Ok.

If it boots directly into the fastboot screen, the trackball is the only button you can press to get directly there on boot. I don't see it being any other problem.
I just tried to access fastboot on my fire and pushed the wrong button.
When holding "Volume Up" while switching the device on, it shows "Factory APK mode..." on the screen. After releasing the button the message disappears after 2 seconds and the fire boots up normal.
Nothing has happend, it works normal and all apps still work the way they did before.
So what does that mode do?

Likely just safe mode, only stock apps load, when in safe mode.
Used to boot device if a non stock app is causing device to be unusable.
But why do play store and so on still work when booting into that mode?
It just displays the message while booting, but nothing changes when up and running.
5.0.0 or 5.0.1 ? mine boots on fastboot mode
5.0.1, I can take a picture of it later today, didn't know there might be a difference in the versions.
I can only get fastboot ... Are you able to do this reliably? I've tried different hold an release and timings but can get it to happen.
Sorry for the late reply.
I tried to take a photo of it displaying the mode, but my phone couldn't produce a good one, so I finally took a short video. Focus is bad but you can sometimes read it.
I can repeat the process every time: Power down, hold volume up key, power on -> factory APK mode.
Hope that helps you.
Can nobody proove this works?
I mean I can't be the only one with that mode and I'm still wondering what it does.
stays now in fastbootmode - help
Tried that, now it is showing fastbootmode, nothing else happens.
It's stuck in there, it does not react on buttons, nor is it seen by adb.
What can I do to get it back to life?
[Update]
Meanwhile I googled, installed Android SDK, went to platform-tools and tried adb and fastboot.exe.
adb devices gives an empty line.
fastboot devices gives the tablets serial and the word fastboot
fastboot in conjunktion with reboot, reboot-bootloader, continue tries but does nothing on the tablet.
Looks as if I have to wait until the batterie gives up, what do you think?

not shure but this worked on the older fires.
Success!
Thanks a lot!
My v5.0.1 german tablet boots into
- recovery mode with volume down + power on keys pressed
- fastboot mode with volume up + power on keys pressed.
Recovery mode says:
Amazon system recovery <3e>
Volume up/down to move highlight;
enter button to select.
reboot system now
apply update from ADB
wipe data/factory reset
wipe cache partition
reboot to bootloader
power down
view recovery logs
I have this same problem on my fire that I have only bootloader 5.1.1 and tablet does not start and I can not enter the recovery I wonder if I can help solve
I have 2 Fire 5th gens, 5.1.1, and both have the factory APK mode on vol up button and fastboot mode on vol down. NO recovery mode option. I can't even make it boot into recovery using fastboot reboot commands.
I'm trying to install a custom ROM onto my Xperia XZ1 Compact but I got stuck in the beginning. The first step would be to unlock the bootloader. I followed multiple tutorials but none of them worked for me, because I can't get my phone to reboot into fastboot mode. I tried two ways basically:
1. Turn off device, hold Volume down button for 2 secs, plug USB while holding the button. Nope, nothing happens, the only thing I get is the green led is on, I guess indicating that the phone is being charged.
2. Turn off device, plug USB and launch the command adb reboot fastboot (My computer is running Linux but I think it doesn't matter). The phone turns off but does not restart. If I just do adb reboot it reboots in normal mode. I also tried adb reboot bootloader but it just turns off the phone.
Any ideas what I'm doing wrong? Thanks

It seems that this issue is now solved. Black screen with green led on means that your phone is in fastboot mode. Do not expect any feedback on the screen.

Green = Flash mode, Blue = Fastboot mode.

I see, thanks. Anyway something is going really bad here, I wish I had never started this. I have managed to unlock the bootloader but the phone does not work now. It hangs at the XPERIA logo and does not respond to power button. It only responds to power + vol up + vol down which restarts the system and hangs again at logo

I'm restoring the phone right now, thanks for the tip. Fingers crossed. Yes, I followed the guide you linked above.
My device went int bootloop suddenly while I was using it. I not able to get in fastboot (when I press Power + Down it shows fastboot window for a sec and reboots again ) or recovery mode(When I press Power + Up, Screen shows up saying no command).
I was using official build(July patch). I have not enabled ADB. My bootloader is also locked.
Is it possible to get this device working?
Any help will be appreciated.

This is normal behavior of stock recovery: seeing "no command" hold "power" and click "Vol+", - to get to the stock recovery menu (btw, search would 100% give you this tip even in these forums).
As you are locked, and thus you have surely lost user data, you can try to make factory reset from recovery menu.
Yet I'd try to connect phone to power and make numerous attempts to reboot, occasionally rebooting into fastboot and into recovery, - with the hope that phone will switch into the other A/B slot.
If nothing helps, TestPoint/EDL is the only option except service.
But again, the problem may be hardware issue, and as you are supposed to disassemble phone preforming TestPoint, I'd check connectors inside and tried to reboot again before reflashing in MiFlash. And do not forget to reflash in fastboot after MiFlash reflash (and unlock phone - which I did immediately after purchase).
