I was always able to ADB shell into my phone after i installed the proper USB drivers as well as Pull up ADB DEVICES no problem and i SAW ADB DEVICE in my device manager
Ok i have finally got to the steps where i have flashed my sappimag.zip file to my Mytouch successfully. that ROM has been flashed and now when i boot the phone up it says VODAFONE and i can get intot he phone fully
I have turned the device off and hold the BACK and POWER button and the FASTBOOT screen comes up. i plug in the USB cable an FASTBOOT changes to FASTBOOT USB ok great.
i pull up CMD and type in ADB SHELL and it says DEVICE NOT FOUND. i type in ADB DEVICES and its blank.
I power down and power back up fully and same thing (but it was working before the flash of sappimg.zip)
i downloaded and installed HTC SYNC which supopsedly has updated XP drivers and it did.
i power down phone and power back up as normal and pull up CMD ADB SHELL works fine and ADB DEVICES shows my serial number. ok making progress.
I have turned the device off and hold the BACK and POWER button and the FASTBOOT screen comes up. i plug in the USB cable an FASTBOOT changes to FASTBOOT USB ok great.
i pull up CMD and type in ADB SHELL and it says DEVICE NOT FOUND. i type in ADB DEVICES and its blank still again.
what gives? why does this only work now with phone fully booted and not in fastboot mode?
also note my device manager no longer has ADB DEVICE anymore its gone.
adb doesn't work in fastboot mode.
edit for clarity: When you boot the phone in fastboot mode, adb isn't supposed to work. You have to boot fully, or boot into one of the recovery images that supports adb for it to work, fastboot doesn't support adb at all.

ok so what does this mean in the directions then? how am i supposed to perform the below directions in red then?
FLASH your T-Mobile myTouch 3G
Make sure are using fastboot from the latest SDK (release 3) !
- Power-off your device
- Insert the goldcard
- Power on while holding volume down (of fastboot your device and then press volume down)
- It should pick up the sappimg.zip and you should be able to flash it.
- Once the flashing is FULLY finished power off your device.
- Remove the goldcard and insert the SD (with update.zip)
- Power on while holding back (=fastboot) and connect the USB cable
- Download my RAv1.2.0H recovery and fastboot it :
Code:
fastboot boot recovery-RAv1.2.0H.img
it means exactly what it says:
Download the recovery image to your computer then, from your computer, run the command:
"fastboot boot recovery-image-name.img"
fastboot is a command line utility that comes with the android sdk. It allows you to push recovery images to the phone while it's in fastboot mode and boot them.
adb is used to communicate with the phone while it's running an android image, NOT while it's in fastboot mode.

ok i understand what you mean and say BUT look at the directions and it clearly says:
POWER ON WHILE HOLDING BACK (FASTBOOT) and then CONNECT USB
when i read that it makes me thnk think literal and to hold the Back button my my device and hold power and watch it come into fas boot mode and then when itmentions connect USB it makes me think im supposed to go into ADB shell commadn and then type that command in.
so im definately not trying to argue with you just trying to get you to se my point of view on why i am confused thats all.
i really apreciate your help on this.

ok one thing that again is confusing is that you say ADB can not recognize the phone while in fastboot mode but then you said i use the fastboot command line to push recovery images to the phone while its in fastboot mode.
how am i suppose to do that if the ADB shell (where i run the fastboot command line from) does not work if the phone is in fastboot mode (the mode it has to be in to accept recovery images)
see what i mean very confusing.
i just rebooted my phone normal. connected it to USB and went into CMD and ADB shell comes up fine
i typed in ADB SHELL
and then :
# fastboot boot recovery-RAv1.2.0H.img
and it says:
C:\>adb shell
# fastboot boot recovery-RAv1.2.0H.img
fastboot boot recovery-RAv1.2.0H.img
fastboot: not found
fastboot is different from adb........
2 different programs. adb.exe and fastboot.exe
just place the fastboot.exe file from the sdk into system32.
and try to put the recovery file in to the sdcard.
rename it to recovery.img to prevent misspelling .

ok thanks everyone i got everything i wanted above.
I guess my Mytouch is now rooted? but wth a 32A radio?
i want to flash a 32B cyanogen 3.9.10 rom onto this device and using the directions below:
For Daredevils : Perform the following steps only if you want to revert to a 32B based radio and ROM.
Revert to 32B Radio and ROM :
- Download your favorite 32B ROM and copy it to your sdcard
- Download the Ion radio image from the HTC site.
- Extract radio.img from ota-radio-2_22_19_26I.zip using your favorite rar/zip program.
- Download my 32B RAv1.2.0G recovery.
- Fastboot your mobile and connect it via USB :
where it says copy your favorite ROM to your SD card well the ROM name i want is called "update-cm-3.9.10-signed.zip"
do i need to rename it to anything? or just leave it as it is?
do i literally just copy that file to my clean empty SD card no renaming to UPDATE or something like that?
Hi everybody, it's my first message here for a big promblem to solve.
First of all my Sapphire version is 32A SHIP S-ON H
I tried to install a Hero version on my Magic by following a recent tutorial.
- I tried to use ecovery-RAv1.2.0H.img (and older version) without success.
- After copying a JACxHERO version (and rename --> update.zip on the SD Card), I lauched the update with daldroid-recovery.img.
- The phone doesn't start (blocked with HTC Magic on the screen)
Problems:
- The backup I did with daldroid doesn't work
- My phone doesn't boot normally anymore
- I can't access the SD Card anymore (with Windows | Dos )
- The USB drivers are correctly installed
What is THE solution to reset the phone (by putting an original version of android on it)???
Thanks a lot for your help!

"update-cm-3.9.10-signed.zip" is perfect. Copy it to the SD, but rename to update.zip JIC.

thank you
With Amon_RA's RAv1.2.0 recovery you don't need to rename . I keep my favourite roms in my sd card and switch back and forth all the time
You just select (when fastbooted into recovery) Flash - Choose .zip, and you get a list with all .zip files on sd card root Sweeeet
Start asking your questions in the right sub-forum (Q&A) (Theme) or even in (General), or i will be forced to ban you for 3 days or till you learn.
Thanks
Thread Trashed!!
Hey folks,
I´ve ran my MZ601 xoom on EOS builds over the last 1,5 years.
Obviously its unlocked and rooted. Currently its running CWM Recovery 4.0.0.4
Now I want to go back to stock to install the latest official updates to get the updated drivers for the UMTS radio/modem module.
After that I want to unlock and get root again to use any of the lastest custom Roms again.
Switching to a touch based recovery would be nice too.
I surfed around a bit and I´m rather confused which steps I need to perform in order to do this.
I guess I need to remove root and lock the bootloader again before I can install official updates ?
Could someone please toss me in the right direction? Maybe some step-by step list?
You'll presumably want Build H.6.1-38-1 for Retail Europe from here.
Returning to stock:
Extract the files from the link above to your adb/fastboot directory if you have one. If you don't have one I've uploaded them for you here.
Connect your Xoom to your PC then open command prompt from your adb folder. (Hold shift > right click on adb-fastboot folder > click Open Command Window Here)
Type adb devices and hit enter, if no devices are listed then ensure USB debugging is switched on in Settings > Development > and tick USB Debugging, then try again.
If it still doesn't appear then download Motorola USB drivers here and try again.
If fine then run:
adb reboot bootloaderThen run the following to flash the stock image:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
Flashing userdata.img is going to remove all your files so back everything up first.
This should unroot your Xoom anyway, not entirely sure if the lock is required to receive updates, but it's simple to unlock again.
Once booted and through initial setup you should receive several over the air updates. (I believe the stock image is Android 3.2)
Unlock:
Connect your Xoom again and open command window in the adb-fastboot folder as before.
Run:
adb reboot bootloader
fastboot oem unlock
fastboot rebootYou'll now be unlocked.
Install Touch Recovery and Root:
Next download ClockworkMod Touch recovery from here, rename it to just recovery.img for simplicity, and copy the image to the adb-fasboot folder.
Download Xoom Universal Root from here.
Copy that file to your sdcard.
Then run:
adb reboot bootloader
fastboot flash recovery recovery.img(assuming you renamed it)
Once verified, reboot by holding Volume up and Power. (Keep connected to PC and keep command prompt open)
Important: When you see the Motorola logo wait about 3 seconds and hit volume down. You should see 'Android Recovery' in the top left corner, now press volume up to enter recovery.
From recovery go, Install zip from sdcard > choose zip > and select Xoom-Universal-Root.zip
Important: After the root flashes do not reboot.
Run:
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.oldThen select reboot in ClockworkMod recovery and boot as normal.
If you are unable to use adb in recovery, then you can enable this through Windows by doing the following:
Whilst in recovery and connected to your PC, open Device Manager, find your Xoom, usually under 'Other devices'.
Then right click on your Xoom > Update driver software... > Browse my computer for driver software > Let me pick from a list of device drivers on my computer > Pick your Xoom (either one if there's two shown)
Windows should confirm the driver installed then adb should work in recovery.
Finally, run:
adb reboot recoveryIf ClockworkMod touch recovery is still there then all is good!
Hopefully I've made sense! Any questions, just ask.
Repeat of downloads:
Download Motorola USB Drivers (Device Manager) here.
Download ClockworkMod Touch recovery here.
Download Xoom Universal Root here.
Wow, what a detailed guide
Thank you sir
No problem!
Let me know how it goes, hopefully shouldn't have any problems.
Resetting worked great :good:
Right now I´m in an OTA marathon
all that unlock, root and recovery stuff sounds familiar so I don´t expect any problems.
Thanks so far :good:

Ok, so this is not working
after I flash touch recovery and do thta reboot thing I can enter touch recovery, thats fine.
Flashing universal root, fine.
THEN,
adb remount
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old
gives me error since in recovery mode there ist no adb connection
Whatever when I choose to reboot the system, recovery warns me that it will get overwritten by boot and ask me to disable this.
Shall I do this?
EDIT: Nevermind, I decided to be a little brave and just confirmed that message.
Now touch clockwork seems to be persistent and I´m a happy Xoomer again
Sorry, I had meant to reply during my lunch break.
Edit: Realised the time on the second of your posts, so wouldn't have been much help on my lunch anyway
Well I believe I just learned something new!
Either that or I'd forgotten it asked.
I assume it disables the action rather than deletes those files.
My method was just so you can use the reverse rename in future to re-enable the overwrite on boot.
In future, not that you'll necessarily ever need this information, you can enable adb in recovery through windows by doing the following
When in recovery and connected to your PC, open Device Manager, find your phone, usually under 'Other Devices'.
Then right click > Update driver > Browse my computer > Let me pick from list > Pick your phone (either one if there's two shown)
Should confirm driver installed then adb should work.
I didn't include the above previously as I couldn't remember having to do it personally.
Glad to hear all is well though!

No problem, I'd be honored!
This is how i fix my TF300TG stuck on recovery. I hope the steps descried below will help.
Long story, short:
For some reasons, seems like the WIPE command from TWRP and CWM recovery screw the partitions.
No partitions or microSD card can be mounted.
The tablet is now booting only in recovery mode or in fastboot mode (the screen with three icons - RTK, Android and WIPE) instead of Android.
IMPORTANT:
If your tablet reboot in fastboot mode DONT WIPE IT AGAIN! Just skip step 4.
First of all, MAKE SURE YOR BATTERY IS CHARGED!
Recharge your tablet for at least two hours.During the flashing process the tablet doesn`t charge.
Use the original Asus USB cable that came with the tablet or a high quality replacement cable. Cheap cables can and will cause problems.
Use a laptop or desktop with known good USB ports. If you have problems, try a diferent computer, some USB chips can cause troubles.
Disable the antivirus or screensaver, sleep etc...
1.Download these files:
from ASUS website: http://www.asus.com/Tablets_Mobile/ASUS_Transformer_Pad_TF300TG/#support
Drivers&Tools, on the OS tab select Android
click on Utilities and download latest version of ASUS PC Sync (you will need this for drivers)
click on Firmware and download the lastest available (you will need this for BLOB file)
Minimal ADB and Fastboot: http://d-h.st/gbx
install ASUS PC Sync and Minimal ADB and Fastboot (on fastboot installer check the box that make a shortcut to desktop)
unzip the firmware file downloaded from ASUS site
you will get a second zip file, unzip this one too
the folder unzipped from the second one contain a file called blob
copy or move the folder to the root of your drive C: or D: or whatever drive letter you have
2.Installing drivers:
connect your tablet to PC
you will get a message about Windows couldnt find driver bla...bla, ignore it and keep your tablet plugged
IMPORTANT: even if you previously installed ASUS PC Sync or other drivers and Windows recognize your tablet, you still need to change the driver.
right-click on My Computer-Properties and click Device Manager
find the Asus Android device - should be with an exclamation mark on it (the driver is not installed sign)
right-click on it and choose:
Update Driver Software..., Browse my computer for driver software, Let me pick from a list of device drivers on my computer, Have disk, Browse
go to C:\Program Files or Program Files (x86), ASUS, ASUS Android USB Drivers, Android and select android_winusb.inf
Asus Android Composite ADB interface will appear in the list of device drivers - don`t hit next yet!
uncheck Show Compatible Hardware and select Asus Android Bootloader Interface from the list, now hit next
3.ADB mode:
open Minimal ADB and Fastboot from desktop - from this point, keep it open
type: adb devices - and you should see some numbers under the List of device attached - thats your tablet
if you can`t see the tablet, try this command: adb start-server
4.Booting to "fastboot":
there are two ways to do this:
a) from adb window type: adb reboot bootloader
or
b) reset and hold vol-down (didn`t work for me, but maybe will work for someone else)
the three icons will appear on screen - NOW YOU ARE IN FASTBOOT MODE
if none of the above work try this:
in adb window type: adb reboot
wait until the tablet enter in recovery menu and type in adb window:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb reboot bootloader
5. Flasing the blob
the credits for this part goes to buster99. He is the one who figured out the right commands for formatting partitions and flashing back the OS
here is his post: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
here we go, one at the time in adb window:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system x:\your blob folder\blob (here you enter the path to your blob file, must end with blob, to point at the file)
fastboot -i 0x0B05 reboot
THE FLASH SYSTEM COMMAND WILL TAKE SOME TIME
be pacient and wait until the progress bar is 100% full on the tablet and you get the command prompt back in the adb window.
After reboot, the Android is back on.
Cheers and good luck!!
A big thank you alexhosu,
several months ago that my tablet was blocked, but I still kept hope
a solution would be found. I'm really happy for you and thank you again for sharing.
Long live XDA
me too
Thanks from me too; was enjoying 5.0 (timduru) on my TF300 when I went to upgrade and idiotically managed to get into a TWRP bootloop(interrupted a format of \data and then used 'wipe' from the boot screen by mistake...)
Your solution has saved my tablet
Am now carefully reinstalling Katkiss
Thanks
This saved my (veggie) bacon too, something went wrong when flashing new ROM (most likely user error - e.g. my fault). Tablet woud go into an eternal boot wouldn't finish booting, nandroid recovery did the same. Used this technique and have a working stock ROM from which I intend to reinstall TimDuru's Lollipop.
Thanks again
Followed the instructions.. Worked well, but getting error 963 when installing/updating anything in Play Store. Seems to be related to storage permissions. Some users are suggesting using format instead of erase. What's the difference? Could that help.
I did factory reset, reflashed and used fix permissions in TWRP but no luck...

Big thanks from me.
I killed my tablet with an accidental restore to factory defaults while in cm12, an got stuck in an endless bootloader boot loop.
my tablet came back too life at the end of section 4 after adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3.
although getting adb to talk to the tablet was a fluke.
I just kept trying to send "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" while the tablet was loading (boot looping)
6 months of believing my tablet was dead, after letting CM12 do its own update thing, and now, thanks to the above instructions, I'm back online and its working with the stock rom.
Thank you so much for this. No idea why I couldn't find these instructions before, then I just gave up, back in business now!
Thanks a lot for your guide, this is what helped me fortunately unbrick my device, i was stuck in a boot loop with a broken recovery
Another tablet saved. Know your work is appreciated.
i have the same problem, the system doesn't pass the ASUS logo, i tired to log into fastboot (reset + volume down) and i was able to see the three icons but adb doesn't recognize my device. i see the drivers are correctly installed but no working adb. Any help is highly appreciated.

Did you try entering "fastboot devices" or just "adb devices"? adb wont find your device in the bootloader, but using fastboot commands should unless it truly is not connecting for some reason.

I would try moving the blob to the root of the C drive and try the 7th command "fastboot -i 0x0B05 flash system C:\blob" just to make sure sometime of file permission type issue isn't happening on the pc side. Other than that the only kind of issue I think it could be would have to be the connection with the drivers, although if erasing the partition's works fine, I don't really see what could be going on.
I followed all the steps and delete, but when loading the file update.blob I get this error:
C: \ Users \ mikel> C: \ Users \ mikel \ Android \ android-sdk \ platform-tools \ fastboot flash system update.blob
error: can not load 'update.blob'
Can someone help me out?

Hey, I know that I'm a couple years late on this. But, I was just given a Asus Transformer TF300T, and attempted to install the Kisskat custom rom. I unlocked the device with little issues. Rooted with little issues. But when it came to flashing the rom. I get his error saying that "no MD5 file found" and holds it there for a couple of minutes. Then gives me the failed install. My only option is to boot into recovery and restore the stock JB 4.2. If you could point me in the right direction, I would greatly appreciate it. I've searched the forum for someone with a similar issue, and couldn't find it. I hope that I'm not alone on this one. It would kill me to be stuck with the stock rom.

Muito obrigado!
I know this must seem odd, being such an old thread and all but, after several years adding apps and changing ROMs on my wife's TF300T (my gift!) only these past weeks I had the need to search for help, after installing nougatella 7.1, which I did with success, only to stumble on endless logo loops and loading processes without conclusion. Don't get me wrong, the ROM looks great and it wasn't that hard to install but, after two weeks or so, gave me this problem and after correcting it and installing again the ROM, I got in trouble again...
After some five hours googling and trying different stuff, I finally found this thread and twenty minutes ago (around 2:AM) my ASUS returned to its (Jellybean) life!
Alexhosu, thank you so very much for such a detailed, yet easy to follow guide and, if you happen to come to Portugal on vacation and visit Setúbal, I'll have a bottle of Moscatel waiting for you!
Many thanks to Droidbound (who got me off the hook the first time the tablet went nuts!), and also Kevinthefixer, Gtanner00 and some other very inteligent, patient and thoughtful people, and all the guys who shared their difficulties and in a way helped me find the people with the fix.
For anyone interested in trying this method, I would say that it's paramount that you should stick exactly with what is asked and should pay real atention to what is the correct ROM update to download and use. If anyone needs help with translation to Portuguese, just say so.
Again, thank you so much for this!

This is how i fix my TF300TG stuck on recovery. I hope the steps descried below will help.
if none of the above work try this:
in adb window type: adb reboot
wait until the tablet enter in recovery menu and type in adb window:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb reboot bootloader

Thanks for your help :good: and I'm sorry for my basic English, but here is another tablet saved. Your instructions were clear and my tablet is working.
I hope this information helps, based in the next link (user sszyman): https://forum.xda-developers.com/showthread.php?t=2275035&page=9
in which he recommends using the following commands too:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p2
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p8
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p1
With these commands and "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" I was able to solve my Bootloop problem.
Honestly I don't know which of the commands worked, I used all several times.
Download
Search for TWRP recovery for LG V10 H901 (File: twrp-2.8.7.0-h901.img (31.7 MB))
Backup Apps and Data
While this process should not wipe any of your data, a backup is highly recommended. Once you install a custom recovery like TWRP, make sure you backup your system, data,etc. from the recovery. It will be helpful in case anything goes wrong.
Prerequisites
This guide is compatible with LG V10 H901 only. Do not try it on any other devices or variants.
Unlocked bootloader is required to install a custom recovery like TWRP on your device. Click here.
Set up ADB and Fastboot on your computer. You can download the minimal ADB and fastboot tool from here (unzip it) or get the quick ADB and fastboot installer from here.
Install Motorola USB Drivers on your computer.
Open Settings> Developer options and enable USB Debugging on your device.
Go to Developer options and enable Allow oem unlock.
How to Install TWRP Recovery on LG V10 H901
Download the recovery image file. Extract if in case a zip file. Now transfer the file to your PC where you can easily locate it.
Make sure you have setup ADB and fastboot on your PC. Also accept Always allow from this computer when you plug in the device for first time to enable USB Debugging.
Now power off your device and unplug it from your PC.
Boot into the bootloader or fastboot mode. To do so, press and hold volume down and the power button simultaneously for 5-6 seconds. When you see the bootloader screen, connect your device to the PC using a USB cable.(Choose fasboot if option is available) Alternatively, you can also issue the following command through your cmd or terminal, while connected to the PC in order to boot into the bootloader.
"adb reboot bootloader"
Navigate to the location where you have placed the recovery file. Rename the recovery file to a simple one, like recovery.img. While the folder with recovery.img file is open, hold shift key on keyboard and right-click on an empty space and select “Open command window here” option to launch a cmd window.
Now issue the following command in the command prompt to check your device connectivity
"fastboot devices"
Now flash custom recovery. Issue the following command for that.
"fastboot flash recovery recovery.img"
Custom recovery will now be installed on your device. Now boot your phone in recovery mode. You can do this by turning your device off and then press and hold volume down and power keys at the same time. Or you can simply enter the following command.
"fastboot boot recovery.img"
Once into the recovery, you can backup your current ROM, data, EFS and more.
Once you have installed TWRP, you are all set to install custom packages onto the device’s system. Alternatively, while on Linux or Mac OS, you can issue “./fastboot flash recovery recovery.img” command to flash the TWRP recovery.
Root
As you already have TWRP, simply flash the SuperSU file (version 2.56) to gain root access
@TheJesus @KAsp3rd, thanks guys for everything you've done over the past few days. no shade to @joe01gun but if people are going to use these instructions make sure you search the rest of the forum for what thejesus and kasp3rd put together to get us to this point - definitely appreciated. thanks @joe01gun for putting these additional instructions together.
Your post says the following:
Set up ADB and Fastboot on your computer. You can download the minimal ADB and fastboot tool from here (unzip it) or get the quick ADB and fastboot installer from here.
yet, there's no link to the necessary files to "unzip" them. Any suggestions?
Thank you for the help, but where do we get fastboot set up on our PCs? Yes, this is getting confusing with the steps outlined above. I followed the first step and had to take out the battery because I was stuck in fastboot screen with small tiny text in the top left that didn't respond to any manipulation with the volume keys on the back of the device and wouldn't restart any way until I took out the battery.

I think it's cause he's not allowed to post links yet cause he's too new. I followed this guide http://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930
You can get twrp from the development forum.

Your condensed thread is more convoluted than the actual development thread which also includes the links to everything.
I'm still wondering why you have install Motorola USB drivers for an LG phone..
Understood
Understood
The one on development is straightforward and I managed to make it done.
If you don't lock the bootloader back, you will see bootloader unlocked when starting up.
If you have root enabled file explorer, you should remove /system/priv-app/adaptclient folder to avoid annoying root request from adapt.
Please use the main dev thread for instructions on what to do, found below. Having duplicates for what is essentially the same thing can cause confusion and just takes up unnecessary space. So I have closed the thread.
[Recovery][LG-H901] Unofficial TWRP
Forum moderator,
matt4321
For background, I have Verizon pixel 2 and am using a Mac.
I went down a massive rabbit hole last night reading through these forums and all the posts and was able to unlock bootloader, flash the January OTA and then root by doing the modified boot file with magisk. (interestingly enough the booting into recovery gives me red ! Over a dead Android and I could not load the OTA that way, nor did the adb sideload OTA comand work either, I had to push the extracted walleye img and then the zip file as discussed in one of the steps in some other thread here)
So anywho, in the end I now have a phone that gives me 2 errors when it reboots, one for unlocked bootloader and another for root telling me something is wrong with my phone and i should contact the manufacturer (which I read on here is normal), but my biggest issue is that my ADT alarm app doesn't work anymore (even if i check it off for hide in magisk). I feel like the root is just not worth it for me and I want to revert to completely stock image, even if it resets my phone and I have to re back everything up all over again like did when i had to do the unlocking of the boot loader.
So -- What are the steps I should take?
1)uninstall magisk from magisk manager?
2)delete magisk manager?
The above will unroot me, correct?
3)Do I push the stock boot image file onto the phone?
4) do I have to repush the latest OTA walleye image and zip file onto the phone again?
5) do I then do the adb reboot and do the flashing lock command (same command i did to unlock the boot loader) to lock up the bootloader and reset to stock?
If someone could be as explicit as possible in correctiong or validating my steps above it would be much, much appreciated.
I don't want to do any more unnecessary steps in flashing things than is needed so if I have extra steps above (perhaps 4 is not needed?) Let me know.
Thanks
Proceed with Caution
I am not an expert by any means, but can speak from personal experience. I was in the exact same situation as you. I followed the detailed steps to unlock the bootloader on my pixel 2, received similar issues, and the same prompt when the phone rebooted. All that to say proceed with caution.
My thoughts on questions 1 & 2: I personally wouldn't recommend you remove or delete magisk from the manager. When I did i had to reinstall it via twrp. My phone functioned fine, apart from the error at reboot.
My thoughts on questions 3 -5: When I followed the steps on XDA for your questions here I ended up bricking my Pixel 2 with locked bootloader from Verizon. Probably an error on my part, but wouldn't want someone else to go through the headache, hours of issues, and then an expensive paper weight.
My suggestion would be to:
1. Leave your phone as is and attempt to trouble shoot the app or apps you are having issue with
2. contact Google support on your phone and see if they would replace it
3. wait for an established method to unroot the pixel 2 here
Thankfully Google replaced my phone due to the error after rebooting, prior to me bricking it. I knew I had a replacement phone coming. So I attempted to go back to stock and that is when I messed it up.
Note sure this is exactly what you were looking for, but hope this helps you.
Dozens of posts with hundreds of pages on how to root but no advice on how to go back to stock cleanly?

Your version is Verizon which is making things more complicated. Generally when the bootloader is unlocked, you just hit flash-all.bat and then relock the phone. Given that the Verizon I'm not sure.
So you are on stock ROM with all these apks loaded ? If you go to settings, then do a factory data reset, you'll reset the phone back to stock and completely wipe the phone and return it to stock, at that point you can go into bootloader mode and relock.
Again your bootloader is unlocked, so the flash-all is your best option. If you see the red exclamation point with the error android laying on his back, you press power and up volume and toggle that and it will bring in the stock recovery which you can sideload the OTA however it may fail since you have magisk.
I bought my phone stock last year and have not rooted it or modified it in anyway. Too many problems and it only gets harder and harder as Google releases a new phone.
@mikeprius -- thank you for replying. after reading more on here, it seems like that's the way to go -- flash-all script, seems like i don't really need to do 1&2 that i wrote above as the flash-all will wipe that out by itself.
at that point i should be running the latest stock 8.1 but with an unlocked bootloader (and according boot up message screen) and i should be able to re-do the fastbook unlocking command to lock the phone back up.
(and yes, after reading even more now -- and i tried this yesterday -- i completely missed the portion about PWR + Vol Up button, that's why i think i had that issue, but still, i was able to push the update by pushing img and then the zip through).

If I were in your situation and the bootloader is unlocked, just use flash-all which has a wipe script then call it a day. I think trying to screw around even more is just a waste of time and I wouldn't even bother with the OTA, just erase and flash stock. You don't have to relock your bootloader if you don't want to, if you stay fully stock you may still be able to get OTA updates. I'm not sure if a bootloader locked is required someone can chime in as it has been awhile since I've done this, but over 1 yr ago, I just kept the bootloader unlocked, kept things stock and everything was good to go. Obviously there are security issues with an unlocked bootloader, but I'm sure you know this already
@mikeprius you keep saying reset/erase, do you suggest i re-set the phone and then flash the stock image?
i was just going to flash the stock image, i figured it already wipes the phone, and locking the bootloader would wipe it again, so what's the point of erasing all data prior?
Not to hijack this thread, but a question to add... I thought that there were kernels that would mask certain things to allow all of those apps to work, and get rid of the "problem with device" message.
Is that correct?

Just flash the stock images. It will auto reset.
Again, don't mess with anything just flash stock images, then go from there.
Also flash the newest version of the stock images out there. The pixel 2 will error if you try to downgrade any version.
here are all the steps to UNROOT and LOCK the boot loader on your Pixel 2 on a Mac (windblows users simply ignore all the "./" references).
1) download the latest ADB tools from google
2) download the latest factory Walleye image
3) unzip files from 1&2 into a common directory
4) edit flash-all.sh file and add "./" infront of every instance of "fastboot" in the script [windows users ignore this step]
5)hook up your phone to your computer in debug and file transfer mode. check that "./adb devices" loads your devide
6)type " ./adb reboot bootloader"
7) check that your device is still connected by typing "./fastboot devices"
8) type "./flash-all.sh"
===the script will run and your phone will be restored to stock, and UNROOTED. upon boot up skip through all of the setup steps and get to the phone settings as fast as you can. enable developer option, enable debug mode, set phone to data transfer ====
9) check that your phone is connect to your computer by "./adb devices"
10) type "./adb reboot bootloader"
11) check your devices is still connected by "./fastboot devices"
12) type "./fastboot flashing lock"
===== this will re-wipe your device again, you'll see the circle of death, and this will LOCK your boot loader back up again======
side note, feel free to skip over the steps where you check that your phone is still connected to the computer (./fastboot devices) if you're less paranoid and comfortable.

hey there. what is the command suppose to look like? every combination I try gives me an error:
first, I don't even enter the Fastboot command the same wayit given me an error:
Asads-MacBook:~ asad$ ./fastboot devices
-bash: ./fastboot: No such file or directory
so I try this: Asads-MacBook:~ asad$ fastboot devices
[serial #] fastboot
these are all the errors I get:
Asads-MacBook:~ asad$ cd /Users/asad/Desktop/walleye-opm1.171019.021
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: fastboot./: No such file or directory
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: ./fastboot: No such file or directory
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
fastboot: usage: unknown command ./flash
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: fastboot./: No such file or directory
...
how is the command suppose to look that I can edit it the right way?
"fastboot: No such file or directory" means that you didn't do step 1, step 3 on the file you didn't download, and there should probably be a "cd /<whatever the 'common directory'>" is. (I just created a directory named adb. That's good enough for me to know what it's for.)
You have to download adb and fastboot (which come in the adb tools file), unzip them to whatever directory you're going to use for flashing the phone, and cd to that directory.
Then, since you're evidently on MacOS, each command has to have ./ in front of it (that says "the current directory"). Try all that, then see what happens.

yayy! that worked!
so i had adb and fastboot in a folder (platform-tools) and i had the factory image in its own seperate folder (walleye-files). i was making the cd; walleye folder and trying to flash-all.sh there.
so i had to put the files from the walleye folder into the platform-tools folder. Then I made platform-tools the cd. now when . i could now follow all the steps from 4-12 and got the pixel 2 the way it was OTB.
thanks!
Great! I'm not a Mac expert (last time I used one was the 128K Mac in 1985), so I'm not sure how to export a path in MacOs, so I gave you the complicated way, but you got it done anyway. (If you ever find out how to add the platform-tools folder to your path, you can leave adb and fastboot in there and keep the ROMs [walleye] in their own folder, cd to it and adb and fastboot will still work.)
