Magisk attempt gone horribly wrong on Pixel 3a, haven't found the answer - Google Pixel 3a Guides, News, & Discussion

So I tried to root my Pixel 3a, long story short it went into a boot loop, I got it back into fastboot mode, but now my pc can't see it. when using "adb devices" search comes up with zilch. when plugged into the pc it knows it's plugged in but I can't see it. Has anyone else seen this, or possibly know a way to at least get me to where I can flash the stock image on?

You have to use "fastboot" commands in fastboot mode. Like ... "fastboot reboot bootloader" or "fastboot boot namearecovery.img" ... You might be able to boot into TWRP recovery and flash the Magisk uninstaller.

call me noob or insane, but it wasn't working, but then I typed that in and it rebooted into fastboot. Off to try to follow these steps and hopefully get this thing working again.

It wasn't working because you were trying to use adb commands while in fastboot.

[Q] Kindle fire totally dead

Sorry to open a new thread...I've been searching for a similar problem with no result...
My KF was bricked in a bootloop with acces through adb or fasboot but i can't solve the problem via KFU o Unbrick tool, so I was trying to install TWRP
The last command a typed in cmd was (big mistake):
"fastboot flash bootloader twrp-blaze-2.0.0RC0.img"
after that the KF shuts down forever... no charging light, no adb, no fastboot, nothing...
plz any idea to revive my KF???

Make/buy a factory cable and fastboot the proper bootloader from the stock update package.
Sent from my myTouch_4G_Slide using XDA App
I was a little confused about this myself at one point... There are a bunch of 'low-level' partitions that are really important not to mix up.
'bootloader' contains the basic bootloader, which loads everything else and you should pretty much never touch it, except to install FireFireFire.
'recovery' is the partition where TWRP or ClockWorkMOD should go.
Finally, 'boot' is what launches Android.
I almost made the same mistake last night installing CWM (it was 2am and my brain+fingers were being stupid)
Anyway OP, it sounds like a factory cable would be your best bet, unless that just tells something to the bootloader, in which case getting a warranty replacement from Amazon might be your only option...
Just remember next time that you want to flash recovery ;-)

I have had a similar situation on my KF. I used a factory cable to solve my issue. Send a private message to SkOrPn with Factory Cable in the subject. His cable is well built and arrived very quick via USPS. Not to mention he sells them at a good price.
Finally I got my factory cable.... but the problem is not fixed..
I connect the Factory cable to KF...in am at the command prompt and no matter what fastboot instruction I put always the same message "waiting for device"
If anyone knows what I should do I really appreciate it...
Try adding the device ID 0bb4:0c01 to your USB configuration

I think you've gotten somewhat misleading information from the previous posters. The factory cable will always put the KF into fastboot mode if (this is a HUGE if) the device has a working bootloader. The bootloader is the piece of software that will put the device into fastboot mode, so without that the factory cable cannot do its job.
I'm quite surprised you were able to break the bootloader by trying to flash that image onto it. In my experience, fastboot flash checks for the size and would fail when I tried to give it something > 256KB for the bootloader... but that's neither here nor there...
If you cannot get a "kindle fire" or the "yellow triangle" to come up on the display, your bootloader is broken. Your last hope is to open up the case and use usbboot to temporarily load a bootloader into memory via USB and use that to flash a permanent bootloader. You'll probably need a case pry tool to do this fairly safely and linux installed because I don't believe usbboot was ever ported to Windows.

[Q]Bricked ?

This is what happens :
1. When I normally turn my N7 on , it goes throught the google logo and gets stuck on the ROM logo .
2. I can get into the bootloader when the USB is plugged off , but i cant get into recovery it just gets stuck on the google logo .
3.If I plug my USB in while in the bootloader the bootloader gets stucked and i cant move around in it or flash anything , but my PC recognize that an android device is connected . (if i get into the bootloader when the USB is allready connected it gets in the bootloader main screen but i cant move) .
So i cant flash , get into the rom or return to stock .
ANY IDEAS ?? please help me :crying::crying:
Bump
Definitely not bricked since of powers on. Fastboot flash the stock image and you should be good as new.

Strange, it shouldn't make a difference whether your USB is plugged or not when trying to get to the recovery.
If you get into the fast boot menu or "boot loader main screen" and you press the volume down button a few times you get no response? Sometimes it takes a few seconds for mine to switch to recovery,etc.
Also, what caused your tablet to get stuck in that state?

If I press the volum dowm bottom while on fast boot menu I can move around the menu if the usb is plugged off , but I can only shutdown or restart the fastboot since the start and recovery options just gets stuck on the google/rom logo if it is plugged in I just gets stuck in the menu and I cant even scroll . yea I waited about half an hour on the google logo trying to get to my recovery and nothing happened .
I JUST DONT KNOW WHAT I DID ! I really dont ! I am an experienced flahser and had been so for almost 2 years now ! I just left my N7 on the table and didnt touch it at all for a week and when I tried to turn it on after that I just got that prob . but I did nothing related to flashing or so - it just happened by staying at the table !
any help ?? PLEASE
I CANT RETURN TO STOCK , if i plugg in the usb fastboot gets stuck .
have you tried charging it on the wall charger to make sure the battery has got a full charge, don't know, just throwing out options
Hmmm, well at least you're able to boot the tablet and get to fastboot menu so its not a hard brick. Sounds like a corrupted partition of sorts if you can't get into ROM or recovery. Someone with more expertise might have a possible solution. I wouldn't lose hope yet.
yes , i did charged it to full batt .
i can get into fastboot but not rom or recovery and when i plugg in usb i have no fastboot , doesnt that mean i wont ever be able to flash ?
if i will make a vid of the prob it will help ?
Get to boot loader and do
fastboot flash recovery C:\File path to recovery on computer
Once you have a recovery installed you can push a ROM to your Nexus via adb.

Or you can always use wugfreshs toolkit and click flash back to stock option and check device won't boot, the same thing happened to me awhile ago and the bootloader problem is cause you have the old bootloader the knew 4.13 bootloader fixed that

Lol just calm down man we're all just trying to help you!
Now, you need to get your N7 into the bootloader, it does not matter if you can't navigate the bootloader on your N7. Once in the bootloader, connect the N7 to your computer with the USB cable.
Once you're connected, make sure you've downloaded the Android SDK and open a command prompt. Navigate your command prompt (make sure you ran that command prompt as administrator) to the "platform-tools" directory.
Once in the platform-tools directory run the following command without quotes:
"fastboot devices"
It should return the serial number for your device, indicating that fastboot sees your N7 and can work with it.
After that type
"fastboot flash recovery *.img"
You'll need to head to clockworkmod.com to download the N7 recovery image. Place the downloaded image in the platform-tools directory and replace "*.img" with the filename of the recovery image you downloaded.
That's it! Unplug your N7 and go into recovery, and sideload whatever ROM you want!
Let us know how it goes!
PS: If fastboot devices shows nothing, we have a bigger problem...

OK. Next thing is to ensure your N7 is properly detected in Windows.
Just head to the device manager. You should see Original Android Interface or something along those lines.
Report back with a screenshot, those are very helpful!

I had similar issues and was able to get back to stock using WugFresh's Nexus Root Toolkit. Highly recommended!
From the same command Window, in the same platform - tools directory, does adb devices show your device?

No Command Error

I went to update to KitKat and it was nearly done and then the "No Command" error came up. My tablet has an unlocked boot loader but isn't rooted. However it was before but I updated it from an OTA and that got rid of it. I've tried booting into recovery etc but the same thing happens.
Anyone have any advice please?
Same exact issue and set up here. Also, maybe I'm just dumb, but I can't get my tablet to turn off either. It just keeps cycling back to the "no command" screen until I do something.

I think that both of you what you see (the "no command") is your stock recovery, if indeed you see an android with a yellow !.
If it is the case to access the menu of the stock recovery press power and tap volume up. The menu will give you the choice of rebooting your Nexus 7.

I can get to the menu but when trying the reboot option, it just cycles the same way again. Back to the android with a red ! and says "No command." I also tried clearing cache and data to no avail. I was going to try using ADB to manually push the update but my computer was recently updated and now I can't get the driver installed for some reason.
I spent too much time messing around with and learning how to do things with my SIII and not enough time with this
Same deal here! Not sure what to do short of wiping and losing my info.
Same here...any advice? Not sure what happened. OTA update too.

Wow, this seems to be widespread, at least somewhat. I'm in same situation. Toolkits, adb, nothing works. I thought this was a soft brick, but now I'm thinking it's toast. Probably doesn't help that I didn't have Dev options enabled along with USB Debugging. I can't even turn it off. Just bootloops after Google logo shows up twice, then to No Command error, then starts over again. I wonder what the hell is causing this. (Device was locked and unrooted)
Same boat here, even sideloaded the factory image via ADB.

If you have android-sdk-windows installed on your computer do not forget to update it through "SDK Manager.exe".
Pushing via ADB didn't work for me. That also failed.
I caved and called Google. Tech support is stumped as well.

I finally got mine working again!
I tried a million different things so I'm going to try and explain my process as simple as I can, I apologize in advance because I am far from an expert...
First, I tried using the method, well some of it, from this thread: http://forum.xda-developers.com/showthread.php?t=1907796
- I would suggest using this thread to get everything set up (drivers, ADB, the factory image downloaded and in the correct file location) I wasn't able to get the drivers working correctly with that route so I ended up using the toolkit to get them working but that thread helped me get all of the system files in the correct location and helped get all of the ADB stuff set up.
Once you have everything set up and your computer recognizes the tablet, (I checked that by opening a cmd prompt and using the command from the original thread above "adb devices"). As long as you see your device, I think you should be good.
From the "No Command" screen I held down Power and Volume + to get the menu to come up. I then chose the Restart option and immediately held Power and Volume -. This got me into the Fastboot Mode.
Once in Fastboot mode I went to the cmd prompt on my computer and used the following commands in this order from this post:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system -w
fastboot flash system system.img
fastboot reboot
*Make sure that all of the image files are in the proper location on your computer otherwise this step is worthless
The tablet then rebooted normally and I was able to set everything up again. Again, I am by no means an expert at all, this is just what worked for me. Try at your own risk.
I hope I covered all of the steps, I tried a million different things last night so they all kind of run together.
I ended up doing and it worked for me as well. Wiped everything though. How can I restore / reinstall my apps w/o needing to download them all again?
Two things: That guide says you must have USB Debugging enabled. Since my wife had this tablet, I did not have dev options enabled at all, including USB debug.
The other thing is that when I run the SDK Manager, nothing happens on my computer. I double click it or try Run as Admin, and a small CMD box flashes on my screen for a millesecond and disappears. That's all.
My wife's 2012 N7 is having this same problem. Unlocked bootloader, but I reflashed factory image and unrooted before giving it to her. She got the OTA last night, and now stuck at No Command.
I've subscribed to this thread, hoping that you guys will have it solved before I get home from work tonight! Would love to not have her lose all her data.
(I was kinda mad that she got the OTA last night and I haven't got it yet on my 2013 N7, but that's another gripe for another thread)

Unfortunately I'm not sure on the SDK manager part. As far as the USB Debugging, I'm 98% sure that I did not have it enabled either. I think I did at one point but after doing several OTA upgrades, I'm sure it got unchecked.

Worked for me! Thanks, I don't believe I had USB Debugging enabled either. Shame it wiped all my data though.
OK, got mine back up and running! I'll just leave what I did here in case anyone can benefit from it.
I first used Wug's Toolkit to download and install the RAW drivers. (Option #4, I believe) They were the only ones that worked for me. I followed the instructions to install them and then when it looped to the No Command screen, I held volume up and power. This got me to the menu, where I chose reboot. I then immediately held down the volume button and power to get into the bootloader screen, where it (thankfully) stopped looping. Then I unlocked the bootloader using the one-click option. Next step was to download and flash factory 4.4 image using the Soft Brick mode. Fastboot recognized my device and pushed the image. Now all is well. Close call... I've already enabled USB Debugging for my wife on this tablet so that crap doesn't happen again. She did lose all her data but she is happy to have a working tablet again instead of a $200 beer coaster.

Fastboot discussion.

I have searched and couldn't find a fastboot thread. So here it is.
I found out fastboot is working on Linux.
Bad news is Windows seems to need another driver for fastboot.
Please help look for a windows driver or make one.
The fastboot commands all seem to work fine.
Here you guys go! Enjoy.
Code:
[SIZE=5][SIZE=3][SIZE=5][SIZE=3]adb reboot-bootloader
fastboot -i 0x1949 command_here[/SIZE][/SIZE][/SIZE][/SIZE]
Just noticed pokey9000 said this but it was overlooked.
pokey9000 said:
That's it. And you're running fastboot as "fastboot -i 0x1949 your_command_here", and you have udev set to allow permissions for that VID (or are running as root) in Linux?

In the Fire TV section a fastboot cable was created by splicing two USB A to B cables together, so that the A to A ends were together which when connected from your computer to the Fire TV on bootup put the device in fastboot mode, in the process then your computer recognized (Running Windows 8 was the example given) the device and installed the proper drivers. Since the devices are similar, a potential solution would be use the cable, have the computer recognize it and install the drivers, then backup the drivers, and share them here for others to use.

I'm quite sure the cable isn't the issue. Also that's just it, I can't get windows to recognize it or find much info about it. The adb driver for the device isn't enough I guess. The funny thing is windows says it's working properly as 'Kindle' for a little while when you plug it in (while in bootloader) then device manager refreshes and reports 'cannot start'. I tried launching 'fastboot devices' many times but still nothing. I think it needs a software fix and not a hardware one but I have no past experience using fastboot. So... noob alert.
btw the driver windows tries to use is ms_comp_mtp(Generic driver installed=true) and adb uses the Amazon one on the fourm here.

I have a problem
I don't think there's ever been a question of getting into fastboot mode by using the adb reboot-bootloader command.
The issue is how to enter fastboot if the device is semi-bricked.
The device has source in the original bootloader to boot into fastboot mode if both volume buttons are pressed while powering on the device. But this has since been altered and now will only work if the device is unlocked.

Is flashing the stock .bin file any different than doing a factory reset?
I am bricked, have root, have adb, can get fastboot using adb reboot-bootloader in windows 8. I also have a Linux box if necessary.

Fastboot works with win8? Not with win7.1 If you have fastboot working with win8 please go to device manager (when your in the bootloader) click properties on the device then look for what driver it uses.

hope all of you, understand what i mean here
i need solution for fix the problem soon. thanks
I think all that works is reboot into fastboot mode. Windows 8 says no drivers are loaded. I tried a command (can't remember what) and it just went out to lunch so... I guess windows 8 isn't working either. Only to put the device in fastboot.
there are three oem commands:
oem device-info
oem idme
oem relock

but it doesn't support oem unlock so there must be another way of unlocking the bootloader, when you try some of the commands the device returns "not allowed for locked hw". Does anyone know what the "hw" is ?
hw = hardware?

Read up on this bud.
Hi,
I have a bricked kindle hdx 8.9 that stops at "Kindle Fire" boot screen. I am a newbie at these things.
Just discovered that it still respond to some adb queries. Sounds like there is still hope to recover... Could it be the bootloader is messed up? Anyway to reload an image boot file to repair?
Also "fastboot reboot-bootloader" puts it into fastboot mode...with the status "ready"....and i just dont know how to proceed. Any one can help?
uhg
Facepalm
just back a little: was rooted in April but with subsequent amazon auto updates - didn't have su status. But I was able to load apps & files, installed vpns, quite a few docs,mp4 files, etc. Not really using much of the new freedom or whatever was left of it... Nothing exciting.
Was working well until one fine sunday afternoon, just 2 weeks ago when it just simply stopped after rebooting from a previous low battery charge. Was told it could be an interrupted routine update when the battery power just fell below threshold - but thot it wouldn't have erase the previous image before the new update is effective. Or it could possibly be a deleted file that is related to the booting process as I did a bit of clean up prior to the last reboot?
In the meantime, I did some adb shell/pull to explore or extract the files, photos,etc in /sdcard & other places back to my PC just in case they were not backup by the cloud. Maybe it was not bricked...but just lost a boot file or something...
In a bad situation, have absolutely zero ADB access as my build.prop is botched (bad permissions) and I did a factory reset in hopes of recovering. There is a "fastboot cable" on amazon that says it will reboot a hdx into fastboot mode, but I'm unsure of it's legitimacy. Help?
here try

I don't quite understand. Why is a special cable required for this? What makes it any different from the standard one that comes with the device?
I don't know if this will add anything to the discussion...but I can confirm fastboot is working on Ubuntu 14.04. I am using a kindle fire HDX 7" and it detects it on devices..and most commands work. Sometimes the terminal must be closed and reopened for commands to go through..
fastboot oem unlock works..or rather it says "Okay" but I'm unable to flash anything.

Need help unlocking bootloader

I've tried several times to unlock the bootloader and it will not respond to any commands once in fastboot mode. I've tried to follow this guide https://www.xda-developers.com/oneplus-6t-unlock-bootloader-root/ but whenever I type "fastboot oem unlock" it just says "waiting for any device" and nothing happens. I have usb debugging enabled and oem unlocking on so I don't know what I'm doing wrong. I have the platform tools from Google installed. I can run adb and type "adb reboot bootloader" and it responds, but after that, no fastboot commands work. I mainly just wanted to root so I could restore my apps and data via Titanium Backup. Is there a temp root solution I can use? Or has anyone else experienced this?
Let me know if you need more info. Hopefully this is an easy one.
What do you get if you run "adb devices"?

Or do you mean run it while it's in fastboot?
I feel like it's something simple I'm missing. I've never had trouble figuring this stuff out. I've been rocking an HTC M8 on VenomRom since forever ago so it was time for an upgrade. I've looked at several different guides, but some of them seem to be incomplete. Like the guide at the official TWRP page says to power off the phone. Then it says to hold volume up to go into fastboot mode. I tried following those instructions to a T, but that didn't actually do anything. It doesn't say where to put the twrp.img file, it just says to run the command to boot the .img. Getting into fastboot isn't a problem. It's that no matter what I do once it's in fastboot, I just get "waiting for any device". I've tried the OnePlus6t Manager because I thought maybe I needed a one-click method. But again, it gets to fastboot and goes nowhere from there.

Do not forget to enable OEM Unlocking in Developer options

Just my 2 cents I'm not an expert but it Might be your drivers or when you installed adb did you do it with administrator rights? The first time tried I couldn't get it to work it wasn't detecting the device in fastboot so I reinstalled adb and then it worked
I just rooted mines today but I went off a YouTube video I looked up and they had everything you needed to download in the description. Took about ten minutes ? I'm not sure if I can put a link on here

I've done that also. Developer options are enabled, USB debugging, and OEM unlocking. Are there newer drivers I need? But if that was an issue, it wouldn't allow me to do "adb reboot bootloader". It'll reboot to fastboot mode, but after typing "fastboot oem unlock" it just says waiting for any device.

Try and post it. It let me post the link to the guide in the initial posting. You could be on to something.
This is where I got my version of ADB. https://developer.android.com/studio/releases/platform-tools It's not so much an "install" as it is unpacking a zip archive.

I did not know it was case-sensitive. I just tried again and it seems to show my devices (I'm transferring files off of my m8 which is why it shows two).
Good call, brother! Where do I go from here?

you need to be careful in fastboot. One wrong command can lead to a catastrophe.
I used the adb installer from the same video. Once you unzip it. It's an .exe file which I granted administrator rights to install... it installs adb and drivers and it worked for me
That's the video and did it to a T
Another thing don't use power shell use command

I'm following a video now. I'm thinking I didn't have the ADB drivers installed so I'm trying that now.
Let us know how it turned out ?

Still getting nowhere. I thought my problem was that I didn't intall the drivers as administrator. So I did it again, following this video https://www.youtube.com/watch?v=B-XZy27wy5o When I reboot into bootloader, I type "fastboot devices" and it just goes right back to the command prompt. Nothing happens. I guess I'm going to try the old fashioned computer restart and see what happens. If all else fails, I can unplug it from the wall and blow on it, lol.
I swear, I've never been this simple before.

::sigh:: Still no joy. Restarted pc, ran adb devices and it showed my phone. So i reboot into bootloader, typed fastboot devices and it still took me right back to the command prompt.

I was thinking that maybe the latest OTA broke the bootloader unlock process, but someone else in this thread said they just unlocked theirs. I don't understand what the issues is. I've followed this video so closely I could re-enact it in my sleep.
Got it! I had two sets of drivers installed so I uninstalled both and it finally recognized my phone in fastboot. My old drivers from my m8 from 2014 were probably interfering with it. I knew it was something simple. I feel like Carl in Sling Blade when they bring him the lawn mower engine and he says "ain't got no gas in it, mmhmmm".
Nice! For a noob I wasn't too far off lol it just had to be one of those two issues
Enjoy happy rooting ?
