Need help... stuck in Fastboot Mode - Google Pixel 3 Questions & Answers

Hi,
My Pixel 3 was rooted with Magisk. After uninstalling it, I lost root, tried to re-root with Magisk and ended up stuck in fastboot mode with "error boot prepare" and now can't exit or power down.
I assume I won't be able to save my data, is there any way to reset/flash stock image?
adb fastboot devices show my Pixel 3
adb fastboot reboot works but goes right back to fastboot mode.
If I'm posting in the wrong forum, can you please direct me to the appropriate one.
Thanks
Martha.

I assume your bootloader is unlocked? Have you tried flashing the factory image with fastboot? I'd first try using the flash-all batch file with the -w removed. That way you might be able to save data.

Thanks for your reply.
After countless tries to flash-all with fastboot as well as flashing different options nothing worked...
I originally rooted my phone from a Mac with no issues. I could still run fastboot reboot and other commands but it would revert back to the fastboot mode.
I finally loaded up Parallels and tried fastboot flash-all from Windows and managed to reset on the first try.
Not sure why it didn't work with my Mac... but I'll always use Windows from now on.
***SOLVED!***

I'm not very familiar with mac's. You need to use the .sh file, which I'm pretty sure you know. But you also need to edit the batch file. Command lines that start with / need to be changed to ./ Or something like that. I don't remember exactly.

[Q] Sticky Bit Fastboot

So... Anyone have any experience getting sticky bit turned off on fastboot? My phone boots to it anytime I try to reboot or do a regular boot up.

Mine did that for a short while after I screwed up a flash, I reflashed boot and while running tossed the adb command to get into fastboot and then left it properly. Haven't seen it since.

To clarify... Flash boot from recovery, while that is running adb reboot bootloader? If that is the case I have a different set of problems to "boot", I can't get my pc to recognize the phone while in recovery. Everything else is recognized, even reinstalled drivers to be certain, pc doesn't even try to install a driver for recovery. Tried both TWRP & CWM.

Memory is fuzzy but I'm pretty sure I did it from fastboot, this happened to me about the time shabby was trying to fastboot boot boot.img and I ended up flashing it instead.

Okay, this will probably help you...while your device is in Sticky Bit Factory Fastboot, open up a command prompt and connect to your device (given you know how to do so in your folder containing your fastboot app and drivers). Then type "fastboot oem fb_mode_clear" This command will allow your device to boot into system normally. Problem is (I think) when a failed flash occurs sometimes it sets your device in that mode and the above command clears it. Another way to manually place a device in the same state you described is to enter this command using fastboot: fastboot oem fb_mode_set. I believe that is how RSD Lite automatically reboots your device into factory fastboot mode after flashing partitions (.mbn) on your system so that it may resume flashing the boot, recovery, and system images, etc. Let me know if it helps.....

TF300t constantly booting into recovery

I have a TF300t that I have been doing custom ROMs on for over a year now. Not to long ago it messed up and I ended up doing a ADB side load of the the current software from ASUS to recover it. I wanted to try CM11 so I followed the directions to get the right version of TWRP installed. I noticed that it was really slow at stuff like wiping cache and dalvik, so I decided to reflash TWRP through ADB instead of a zip file.
All went well and I got into android and went into TWRP to see if everything went okay. I'm in TWRP, but I cannot do anything. Only system will mount and it says I am not rooted and wants to install supersu. If I reboot or power off it just goes back into recovery. Doing the power + vol down will not get me into the bootloader and will instead just power cycle at the ASUS logo.
Any idea on how to fix this, or did I just royally brick my tablet?

When you first reboot back into TWRP, try running fastboot commands. You may be able to reflash your recovery, or follow Buster's recovery method from there on.

I just get stuck at waiting for device. Is there a section I am supposed to be in? Or do I do it from the home screen for twrp? I checked device manager and it does have Transformer listed in other devices.

As in the command:

Else you could try:
Code:
adb reboot bootloader
from the ADB in TWRP and then try fastboot commands.

It's not finding anything and ADB sideload fails. I'm doing the fastboot commands from the fastboot folder I have been using with other fastboot stuff for the TF300.

hmm idk. Im guessing you flashed the wrong version of TWRP, which has ended up in a brick for most users, but they had fastboot access and could later recover it using this: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12. You dont seem to have either ADB or fastboot, and TWRP is in a non working state. You could try reinstalling your fastboot and ADB drivers with the universal naked drivers, and then retrying ADB reboot bootloader and fastboot.
All fixed!
Here is what I did.
1.) Installed naked drivers following the guide at the link provided above. This allowed me to get into the bootloader, but I was unable to successfully flash anything.
2.) So, I followed this guide: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
Probably lost all my user data, but worth it for a working tablet.
HUGE thanks to cmendonc2 for the help and ultimately leading me to the correct solution.

Moto G bricked?

Hey guys this is my first thread, I hope it's in the right section
Here's my problem:
Yesterday my Moto G 2013 with CM12.1 just froze (I could turn the screen on and off but that was it)
I tried opening the reboot menu, which worked, but it got stuck on "rebooting", so I just holded the power key until it turned off.
After that I got to the boot logo, but nothing happened from there, not even the boot animation showing up.
Next I tried to boot into TWRP, but it only got to the TWRP boot logo and nothing happened after that, so I flashed CWM, which I could access, but when trying to flash something it just doesn't progress. When I press "reboot to bootloader" on CWM it just freezes there aswell.
In another thread I read that flashing the gpt.bin should fix everything but it didn't help.
I don't really want to perform a factory reset, because of the data loss, but I think this would be my only option.
My question is:
How can I fix my phone (preferably without a factory reset), for example by getting TWRP to work again, because I have a Backup of my system and a zip of CM12.1 on it?
Btw another thing to mention is that when being in Recovery/System USB doesn't really work, but if my phone is turned off or in bootloader it works just fine.
Try "fastboot boot twrp.img" (or whatever the exact name of your TWRP image is). If it gets at least to the curtain screen, run "adb pull /tmp/recovery.log".

When I try "fastboot boot twrp.img" it reboots and get's stuck at the boot logo of android (Motorola logo) and I can hear the "Device disconnected" sound of windows.
But I flashed TWRP into recovery and it get's to the curtain screen. But it doesn't recognize my phone which might have to do with that as soon as it boots into a system USB just won't work

But adb only works in recovery mode in android, which I can't access right now without deleting everything, right ? And if I delete userdata, will my TWRP backup be deleted, too ? (It's just a backup of my system)

Yes, you do need at least access to recovery mode for adb to work. Try testing TWRP even if it is only partially loading. Also try CWM.
Everything will get erased on internal storage, photos, TWRP backup etc. Unfortunately, you may be left with no alternative.

Okay, thanks for your answer, but as I mentioned before, as soon as I boot into something like recovery or android, USB doesn't really work anymore (though it seemed to work again in android). Will erasing user data fix this (as it seems to be a software problem) or even better fixing it before erasing userdata, so I can backup my files? And if I erase user data and TWRP/CWM/whatever works, but USB won't then I can't really put a system on it, can I ?

Recovery mode ADB can take some effort to make work depending on the version of Windows. Since you obviously want to backup your files, you can try booting into Linux (a livecd will work) and installing adb. Linux adb works without the need for drivers so it may give you access.
If using Ubuntu, the command to install adb/fastboot is:
sudo apt-get install android-tools-adb android-tools-fastboot​

I see what you mean but I got adb to work most times when android was still working (just not in recovery) but I also had problems with charging when the phone was turned on, so I assume it's a problem with android, but I'll search for a Ubuntu Live CD that should be layng around somewhere here (lol) and I'll try it

Thanks, I didn't think abut that :highfive: fastboot works now, but adb doesn't (again when using fastboot boot TWRP.img the terminal shows that it worked but the phone just reboots and is stuck on the Motorola logo and if I flash TWRP it doesn't work either). Maybe I should mention, that I have that screen flickering and like scanline thingy going on when I boot into recovery.

Maybe you can get the phone booting into Android by fastboot flashing the system.sparsechunks from the Factory Firmware Image for your phone.

Stuck in Bootloader (Solved)

So i recently tried flashing a new kernel and for whatever reason my pixel 2 did not like that at all. Upon reboot after flashing it now just goes into the download mode where i have the option to reboot bootloader go into recovery and go into download mode. Normally not a big issue at all but this time when i go to load into recovery or load into Download mode its says Operation Denied. Upon a reboot or trying to reboot into safe mode it says ERROR: Slot unbootable: Load Error. Will ADB still work to flash this? not really sure what to do at this moment.
EDIT: Solved it by using Fastboot and flashing the stock firmware without the -w so far everything is back to normal....know to get that dern kernel again

ADB=system. Fastboot=boot. You can't boot your phone, so you're not in android, thus no ADB devices. Type "fastboot devices" and see if it's recognized.

Good news! So, your best bet at this point would be to re-flash your current factory image, with /w removed. If you still want that same kernel, flash it before Magisk.
Just out of curiosity, what method did you use to flash it in the first place?

It wipes all your data, that's why you remove it from the flash-all.bat script, unless you need to perform a full wipe. Telperion has an excellent guide for installing the lastest software, if you haven't already read it.
I've heard users having back luck flashing kernels in TWRP, as the kernel has something to do with recovery. I always use the method of booting the TWRP image in fastboot, use ADB to push the files to /tmp, and then do an ADB shell TWRP install of those files. TWRP, kernel, then magisk, in that order. I always reinstall all three, just to be on the safe side, and have never had any issues. Takes a little while, but not as long as redoing the whole freaking thing:silly:
Looks like you figured it out, before I finished my reply

Fastboot and ADB not working, please help. Tried multiple PCs already

I was working on rooting my device, and had a working root successfully with Magisk. But then I wanted to remove it and relock my bootloader, that's when the trouble started.
I am able to boot the phone and it is working. I can boot to recovery (stock OEM not TWRP), can boot to bootloader, and can boot and use the Oxygen OS. But I cannot get fastboot to run to lock the bootloader. ADB devices comes up empty. These are the steps that I've tried:
-using it on my chromebook that was working with ADB before the unrooting mess
-installed fastboot and adb along with Oneplus USB drivers on a fresh Windows 8 copy
-2 different red OEM oneplus cables
My goal is to return completely to stock and a locked bootloader. Any help would be appreciated, it really seems to be a phone issue and not a driver issue. Thanks everyone!
Use the unbrick tool. That autolocks bootloader when it flashes stock.

I looked into the tool, but I thought from what I read I had to be in fastboot mode to start. I can't get fastboot or adb to connect. Do you know if it will work without fastboot?

Are you sure you have USB debugging checked in developer options?
Absolutely. Just checked again. I would normally say it was a driver issue, but it was working fine until I flashed a boot.img and also I used a windows pc and a Chromebook and chrome os pretty much comes ready to talk to android phones or of the box. I was wondering if adb could have been messed up during the flashing of boot images.

This was correct and it worked. Phone is restored back to stock with a locked bootloader and everything is working as it should.
