Stuck at google splash screen, ADB doesn't list devices with "ADB Devices" command - Google Pixel 2 XL Questions & Answers

Stuck at google splash screen, ADB doesn't list devices with "ADB Devices" command
I was using Masgisk. I followed the steps from masgisk to restore before i took the OTA. The ota moved to step 2 but then restarted. Now i am stuck at the splash screen. I can get reboot to the bootloader but after I lauch my CMD from the platform tools window and use the command "ADB Devices" nothing is listed. I don't remember enabling usb debugging prior to this. Is there anything i can do to flash something that will not erase my data. If not is there any way i can flash the factory image?

Is your bootloader "fully" unlocked?? Have you tried side loading the OTA? It will not wipe data. From bootloader mode, type in fastboot devices to see if you get your phone ID displayed. The USB debugging part is what's worrying me though! Is OEM unlocking checked off in developer options at least??

Thank you for your reply, yes device state is unlocked and when I use fastboot devices I see something but not when I use adb devices
Edit: I was able to restore the factory image thank you though

[HOW TO] Root only STOCK/No Custom Recovery

Taken FROM http://rootzwiki.com/topic/11732-galaxy-nexus-root-procedure-broken-adb-method-dont-use/
With the big change of YOU WILL BOOT LOOP WAIT FOR ADB TO RESPOND and push all the commands then pull the battery and disconnect your USB cable and reboot normal you should have perm root!
**As always RootzWiki nor myself are responsible if something goes wrong. Root your phone at your own risk with the understanding it will void your warranty and there is always a chance of something going wrong.**
*This method WILL WIPE YOUR DATA*
First download Galaxy Nexus FYA Root Package and extract it to c:\gnexroot (for the purposes of this guide)
Also if you wipe and format remember to re-enable Debug mode before restarting processes listed above.
Method
1. First, navigate to C:\gnexroot and install the Samsung drivers (Samsung_USB_Driver_for_Moblie_Phones_v1_4_6_0.exe)
1. If those drivers dont work download pdanet from here http://forum.xda-dev....php?p=19709279 and let pdanet install the drivers for you. Worked for some of us.
2. With the phone turned OFF, hold VOLUME UP + VOLUME DOWN and power the phone on. This will put you in bootloader mode.
3. Navigate again to C:\gnexroot, and hold SHIFT on your keyboard, and right click in the white space. Then, click 'Open command window here'
4. In the command prompt, type:
fastboot oem unlock
You will be prompted to confirm that you wish to unlock the bootloader. You do, of course.
5. Once the bootloader has been unlocked, it's time to boot up the device using the insecure boot.img (ro.secure=0 set in the ramdisk). This essentially means you have permanent root for the duration of this boot session. In order to boot up using that boot image, simply type:
fastboot boot boot.img
Don't expect to see anything wildly different during the boot process - it will boot as normal.
6. Once the phone has booted, in the command prompt window, type the following commands, pressing enter after each line:
adb root
adb remount
adb push su /system/bin
adb push Superuser.apk /system/app
adb shell chmod 06755 /system/bin/su
adb shell chmod 06755 /system/app/Superuser.apk
adb reboot
Again I did NOT write these steps nor did I take credit for this procedure. My goal was to have all this information easy to access here so people don't brick their new device
Edit:
If you get stuck at the google logo and cannot push adb commands, pull the battery and usb cable then reinsert and reboot. If this doesn't work Reboot into recovery and wipe everything and start over.

If you do a factory restore remember to boot at least once after and re-enable debug mode.
anyone had the issue of not being able to unlock the bootloader?
i ran the command "fastboot oem unlock" and it just sticks at the response: <waiting for device>
but nothing shows on my phone.

I would guess your computer is not recognizing the device. Try installing the drivers and connecting the phone to the computer while it is in normal mode not the bootloader. It should install the drivers correctly that way and your computer will then recognize it when you boot into the bootloader and the commands should work.
yea... you are right... it was the samsung drivers not fully loading. re-installed the drivers then doing a windows update showed that there's a new set of samsung drivers on the windows update that needed to be installed. that did the trick.
The superboot method worked just fine for me.

You must be in recovery mode. Turn the phone off, press volume up and down as well as power. Keep it there until you're in recovery and then unlock.

Its not recovery mode, but fastboot mode. If you are in recovery fastboot won't be recognized. Looks like he got it fixed by checking his drivers.
can you also use this method for a Verizon Galaxy Nexus???
http://forum.xda-developers.com/showthread.php?t=1392310
is there any difference?
Superboot method actually does the same thing as this method from what I read just one is automatic and one is manual.
Being I didn't see anyone else rooting from Verizon I took the time to figure out a manual method so i can verify each step and figure out issues if I ran in to any. With Superboot its either it works or it doesn't there is no playing with procedures.
This should work for other carriers to, I can only verify it for Verizon though.
I get past <adb reboot bootloader> just fine but then when I do a <fastboot oem unlock> it just says "waiting for device" forever. everything is installed but under my drivers it says;
"Android 1.0" drivers not installed.
plz someone help, ive searched all over the net but only found help for HTC phones and 2007 old posts.
edit: I am in "Fastboot mode"
Update the Samsung ADB driver under device manager while you are sitting in the bootloader. I'm bootlooping after pushing the boot.img
got it working, "Note: 1" under this guide fixed it.

GOod. Mine is still bootlooping back to the Google screen with a lock on it.
Booted into recovery, formatted. At least i can boot up now.

Sounds like you didn't successfully unlock your bootloader. Have you resolved this?
Done and rooted. Pushing APK's now.
I would recommend doing a full wipe first. I think something got corrupted during the forced wipe when unlocking.
After wiping, I started over. Unlocked and flashed the boot.img. Got a full normal reboot. Flashed it a second time, and it stayed at the google screen and i could connect to it with ADB. Pushed all the commands and rebooted. Works great.
Thank you.
I assume you need to have adb installed before doing this? Or do the command prompts perform from windows?

I had it previously installed. If you download the zip. its already in there, just run it right from the directory you unzip it from.
I would like to return my phone to stock. Locked, unrooted, and available for OTAs. Is there a way to do this yet?

[Q] Running Stock Android. Download and Fastboot working. Can't boot OS. What now?

This is a followup to this thread.
I got some help at androidcentral.com and now have Fastboot driver installed. I don't have access to ADB mode or the main Android OS. What can I do now to get my phone back to working. My phone can also enter Download mode if that's useful.
I can enter Recovery from Fastboot but then what do I do?
Edit:
Run this command in ADB.
adb backup -apk -noshared -nosystem -all -f C:\backup.ab
Your phone will ask for a password...
Don't put one in.
Once it's finished...
It will say backup complete.
Or your phone might just boot straight up.
Then navigate to recovery.
And factory reset.
Does your phone now boot?
(If not, stop here, and hit me again)
GOOD!
Now get back in fastboot and run:
adb restore C:\backup.ab
This will give you your applications back.
This MIGHT brick you again...but I doubt it.
If so...simply factory reset.
Thanks for the response.
Can I use ADB from recovery mode because I don't have access to the main OS and It was my understanding that you access ADB from the main OS?
If so, I'm using GNex TOOLKIT V5.6. Would I need to boot to CWM Recovery to use ADB or is the stock recovery ok?
I tried using the command in Fastboot and I get the error "adb: unable to connect for backup"
In GNex TOOLKIT at the top is says:
FASTBOOT MODE
List of devices attached
(the phones serial) fastboot
ADB MODE
List of devices attached
(blank space)
Click to expand...
Click to collapse
When i try "adb devices" in the command prompt, I also get "List of devices attached" with a blank line under it.
OK, I gave up on trying to access my data and attempted to do a restore with the toolkit. I had to unlock the bootloader as the first step and after that the system would boot again.
It would be nice if I could have figured out how to reflash the stock bootloader as a first step but I couldn't figure hot if you can or how.
Anyway, I should have unlocked it from day one. If i had, I would have has access to ADB from CWM recovery and would have been able to backup my stuff and access files even with it in the unbootable state it was in.
I guess not unlocking the bootloader was a mistake I need to learn from.
Jubakuba, thanks for trying to help me out.

I think I may have ruined my phone

Hey there
I want to start off by saying I have very little experience with rooting, but am very familiar with jailbreaking apple devices so I figured i could manage.
I have a htc one m8 on rogers network locked. I rooted it and had super user and all that jazz, then flashed AOKP. Then I thought i actually liked the stock HTC sense better, so I tried to "get things back to normal"...lol.
Now im at the point where if i turn my phone on it goes straight to the fastboot screen(?) with all the "fast boot, recovery, factory reset, etc". Since I'm super new to all of this is there anybody that can write some instructions on how to get my phone back to stock? I would really appreciate it after panicking over this for 3 days.
Edit: In the fastboot screen at the top it says ***Tampered*** ***Relocked*** ***security warning**
also when i try to press recovery it shows the htc screen for 1 second then back to the same menu
i found this http://forum.xda-developers.com/showthread.php?t=2710735 but i cannot even get into recovery

While being an expert with rooting and flashing custom recoveries on Samsung devices, I am also new to the world of HTC. Out of curiosity, what happens when you hit factory reset?
Unlock the boot loader again then install twrp recovery then head over to the stock backup thread and flash one of the nandroids for your cid.

Do fastboot devices ... adb commands itself won't work in bootloader, it has to be fastboot commands.
now you have a locked bootloader which means you cant do anything.. so your first step is to unlock it again then flash a custom recovery (TWRP) after that flash the stock rom+ boot.img ( to be safe) make sure it boots. RELOCK the bootloader then flash your firmware.zip.. hope it helps

If it's in bootloader it should show in command prompt when you type fastboot devices after connecting it to PC. If it doesn't then there is a driver problem perhaps. Check to make sure you have HTC drivers installed, or reinstall them. Might as well make sure adb is up to date as well, can do that through the Android SDK Manager. Another possibility might be that the usb cable isn't working correctly, try another cable. Fact of the matter though is, if it's in bootloader and you connect it to the PC adb/fastboot SHOULD pick it up.
So check and fix those things. Also make sure you use the correct commands, in bootloader mode, it'll be fastboot commands, not "adb devices" but "fastboot devices" ... "fastboot reboot" etc etc. Also make sure you're running the commands from within the adb/fastboot folder path(just for in case yeah...)

You didn't read any of my posts about that, did you? lol
I already stated adb commands like "adb devices" "adb reboot" etc will NOT work in bootloader, it'll work in the system and yes, it'll work in recovery for sideloading etc, but NOT in bootloader. For bootloader you HAVE to use fastboot commands, "fastboot devices" "fastboot reboot" "fastboot oem lock" "fastboot oem get_identifier_token" "fastboot flash unlocktoken Unlock_code.bin" etc etc

With that adb devices command again in bootloader? Did you flash TWRP yet? If so, Got to Advanced >>> ADB Sideload >>> Swipe to start sideload.
Place the ROM.zip file in your adb folder then:
Connect phone to PC, while still in recovery mode type adb devices to make sure your device gets picked up, should show you the serial number for device AS WELL as "sideload" next to it, if so then you are hooked up right. Next type adb sideload name_of_zip.zip wait until fully finished.
If sideload fails for one or other reason you can also try to push it. Reboot to recovery again, type adb devices to make sure device gets picked up, type adb push name_of_zip.zip /data/media/0/ or adb push name_of_zip.zip /sdcard/ flash as per usual then.
Yet somehow I don't think you even need to go to these steps

I made a small mistake with the sideload though, it actually installs automatically as such you don't have to go back into recovery to flash, as it did it already, sorry. Edited post to fix.
Well as long as you can get into phone now to copy the nandroid backup to the phone all should be in order, can flash back stock from the nandroid then.
Glad it worked out then.:good:

I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.
Please can you help me. What can i do? Many thanks for your help!

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.
i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“

Enter command "fastboot flashing unlock_critical" gives me error "FAILED (Write to device failed (Too many links))" "fastboot: error: Command failed"

Maybe trying to update your firmware to something closer to current. You're about 3 years out of date....

Then i would suggest that you update your firmware via OTA as Tulsadiver suggested. Then try your unlocking command "fastboot flashing unlock"
The critical one is no longer needed after the 9.0 update. Good luck. :good:

Do you see your serial number when you type:
fastboot devices

Thanks I will consider upgrading the firmware if there is no other solution. I am going to see if I can solve the problem on 8.0 for now.

Entering the command "fastboot devices" gives me nothing. When I try "adb devices" my serial number is displayed.

Are you in fastboot mode or bootloader mode when your typing "fastboot devices"???

I'm not sure of the difference. The screen I attempt to unlock reads FastBoot Mode in red. Fastboot devices is now displaying my phones serial. Adb devices no longer displays serial.
I cannot remember if I had fastboot mode loaded earlier when I attempted the command "Fastboot devices". It is now displaying serial when enter the command while in fastboot mode.

Fastboot mode, or bootloader mode as some call it, is when you enter it when the phone is shut off with the power + volume down buttons, or from ADB reboot bootloader when your phone is on. ADB devices will not work in fastboot/bootloader mode. Conversly speaking, fastboot devices will not work while your in your OS with the phone on. All your fastboot commands must be done from fastboot/bootloader mode. :good:
I'd try out the pixel all in one tool, it makes these things dummy proof. But really, take the OTA and get your phone updated first.
Hi everyone, I recently bought a 2xl pixel and it's updated to Android 10, and I want to change rom (basically why I like to see how much can be done)but I have the problem that it is Verizon version, I have tried to unlock it with the methods I have seen, but I have seen that it depends on the Android version.I would like to know if there is a way to unlock the OEM unlock in order to unlock the bootloader. My model is the Google Pixel 2XL 128GB. Thanks in advance

Sorry to say, if your device is a Verizon carrier variant (not purchased directly from Google), then you will not be able to unlock the bootloader at this time (or likely ever)....
To be sure:
after enabling "Developer Options" if you can't enable the "OEM UNLOCKING" toggle, your bootloader is not unlockable.
