Google Pixel 3a (sargo) brick - error boot prepare - Google Pixel 3a Guides, News, & Discussion

Hi,
Today I wanted change my recovery. I had the Lineage OS recovery, but i was trying to install the twrp recovery.
So, the guide of twrp says that you should boot the twrp via fastboot boot twrp.img and install via the booted twrp. But I mistaken the command and I wrote fastboot flash boot twrp.img, I tried to reboot and the device booted himself in fastboot with the enter reason "error boot prepare" and I can't boot into the system or recovery.
I tried to flash the official image downloaded from the Google Developers website, but when i run ./flash-all.sh, console get stuck. I waited for about 15 minutes but nothing. I tried even the official Android Flash Tool but after 10 seconds it says "Your device stopped responding. You may have to select restart in the bootloader menu in order for it to be recognised again."
Does anyone know how to help me? Thanks in advance.

Yes, I wrote in the post, I tried both the command line tool and the chrome version. Btw i'm on linux

Okay so, I fixed.
For anyone who will have this problem you just need to flash official Android 9 and next Android 10. Only with Android 10 you can use fastboot flash boot recovery.img (you can't use twrp in android 10 with the Pixel 3a)

Does this work if adb not working? I only have fastboot.

It depends if your pc were authorized, if it was, you can use fastboot to flash the stock version of Android 9, just running the flash-all(.bat) script.

I'm not certain I understand what you mean by PC authorized? I'm using a Windows 10 tablet. When the phone is attached to the computer it sees it as a device that can be disconnected through USB.

I just had an encounter with this. I was rooting my device (Pixel 3A) and messed up my partitions through accidentally attempting a downgrade which broke all my ****. I was unable to easily reset this device to factory, so it took me several days to figure out and root. I'm getting better though as a hacker, because a year ago this would have taken me a month.
I was able to enter recovery mode (lying down Android, NO COMMAND). From this recovery mode, adb devices -l recognized my device, although I was unable to get a shell.
At first, ADB was telling me the device was authorized, but I messed with a bunch of other stuff (tried to flash a bunch of different partitions and monkey around in general trying to install Magisk) and then ADB started telling me it wasn't authorized when I used devices -l.
Once it said unauthorized, I was unable to issue the device any commands with ADB, so I just used hardware keys to get into recovery mode. From there, I selected OTA update, and it got into sideload mode. At that point, I used adb sideload with the OTA package that I downloaded here https://developers.google.com/android/ota
^^^ That operation did successfully restore my device to factory
This following guide here describes the details of how to use hard keys to enter recovery on this phone (don't download anything from there tho, and make sure your adblock is on)
How to Hard Reset your new Google Pixel 3a [Tutorial]
In this article, you will learn how to start your Google Pixel 3a up into the Recovery Mode and perform the Hard Reset to make it work perfectly again.
thedroidguy.com

I just wanted to say, I've been wrestling this hardbrick for a couple of days with my Pixel 3a.
I've finally overcome it by sideloading the most recent OTA update after using a hard key combo to get into recovery mode. The hard key combo is hold Power Button, tap Volume Up, then release both. Then, all you need is to use the command:
adb sideload <OTA.zip>
^^^OTA wasn't the actual filename though, you can download OTA packages for Pixel 3A here: https://developers.google.com/android/ota
the OTA binaries are NOT the same as the factory images, which is here
Factory Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
Sideloading the OTA package brought my phone back from only having fastboot and recovery mode, even when flash-all.sh from the official downloaded firmware failed. Now I know how to undo damage that I cause by rooting this thing. Since I sideloaded newest firmware, it was also like applying an update. I easily got root after that, and I've logged the process. I'll make it into a guide soon

I'll just note that if you accidentally flashed the TWRP boot image instead of simply booting into it, I believe all you have to do is flash the stock boot.img to fix the problem. Obviously you can sideload the entire rom image, but that shouldn't be necessary.
Using the Windows computer (or whatever computer you are sending ADB commands from), download the full stock image directly from Google. Unzip it and then upzip the folder inside. You should find the boot.img file inside that folder. Take that file and then flash it to the phone using the normal ADB command: fastboot flash boot boot.img
While I haven't tried this myself recently, it should work in theory. The command "fastboot flash boot twrp.img" flashes the boot partition with a non-working twrp image, so replacing the faulty image with the stock boot.img should fix the problem.

If I did the same I would first attempt to manually put device in bootloader/aka fastboot mode then fastboot flash the stock boot.img , sudo fastboot flash boot boot.img --slot all
I only read the op (first post here);but I betcha that would have worked. Then sudo ./flash-all.sh and let it do it's thing.

Hi... You can't use adb commands while in bootloader... Only fastboot commands. Use the volume rocker till you see recovery mode displayed and press power button. If it still bootloop, try formatting cache and data with fastboot in bootloader and reboot in recovery again. If it still bootloop. Finally try fastboot flash a stock Google image. If none of these steps work, your phone is probably dead and you'll have to try to RMA your N6P.

Fastboot flash-all.sh is for Mac computers so presumably you have a Mac. Flash-all.bat is for windows. You need to unzip the Google image and move everything into the same folder where you have the fastboot program. Just open a command prompt window inside that folder and type the command. That's how I do it in Windows. Presumably the process is similar with a Mac. You will still have a zipped archive after you unzip the Google image but you want to leave that one as is. So far flashing flash-all.bat has gotten me out of every boot loop I've gotten into on my 6P but my phone never spontaneously bootlooped. I was always doing something (updating a rom, trying to restore a nandroid backup) that resulted in a bootloop. The fact that your phone boot looped without warning is probably a bad sign. If you still have warranty I would try to flash stock and see if you can RMA phone. If that isn't possible you might want to try staying on stock or using a different rom and seeing if the random reboots still occur. Good luck.
Well that really sucks. Sorry for your loss but it is a long running phone failure problem. I'm on my second 6P because this. Even worse to me is the fact your were running almost the exact same setup I am now. I refrained from running 7.x.x to try and minimize my chances of another BLOD so now w4on knows what to do. Lol

adb only works while phone is booted into system so nothing wrong there. If you're in the bootloader menu where you see that the status of your device is unlocked then you're already in fastboot mode. Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too. Go into install and press flash image file and find the stock boot image and then go into install again and change to flash .zip and flash magisk. After that, reboot into system.
WOW thank you so much'

No problem. Thank you very much for the donation, that was really kind of you. Hey I'm sure you'll get the hang of it before android P drops. you did figure out what went wrong all by yourself so get a hold of the right boot.img and the rest is exactly as how you did it in the first place but flash the boot.img before magisk. Let me know if you want to give it a dive again.
I'm on 8.1 boot loader unlocked and ready to try to root again .Thanks for the help
This is the closest thread i could find to what is happening to my PH-1.
Like videodave1 I 'was' running the latest stock 8.1 and have my bootloader unlocked. In trying to root the phone I did this:
flash boot flash boot twrp.img
adb shell twrp sideload
adb sideload magisk.zip
All installations went well, but when trying to reboot from twrp it forced me to install the app. After that the phone went into boot loop.
* Note how I didn't sideloaded the Oreo 8.1 image before magisk.
By pressing all 3 buttons I can get the phone to reboot and releasing the volume up I can get to Fastboot. Just volume down and power doesn't work.
The problem now is that adb and fastboot no longer recognise the phone. adb devices just gives an empty list and fastboot only shows < waiting for device >
Trying to go into Recovery mode doesn't work either. Power off doesn't work and Restart bootloader, well, restarts the bootloader.
It might be relevant to mention that I'm running adb and fastboot from Terminal in a Mac and that this is my very first and frustrated attempt to root any phone.
For reference this is what the FastBoot Mode brings:
PRODUCT_NAME - Mata
VARIANT - OPENUS
BOOTLOADER VERSION - mata-aad8ac4
BASEBAND VERSION - 2.0.C4-M1.3.1
SECURE BOOT - yes
DEVICE STATE - unlocked
I might have to just resign myself to the ordinary land of unlocked full stock phones
Thanks very much

I might be missing something hopefully obvious here. How can I flash twrp again if I my computer can't see the phone. With the USB phone plugged in and in the FastBoot screen I enter into Terminal:
fastboot flash boot twrp.img
and I get:

How do I flash it from the FastBoot screen? BTW, going to Recovery mode just hangs at the Essential logo.

Thanks Arju. If you are referring to the FastBoot menu where you can use the up and down volume keys to select Start, Restart Bootloader, Recovery mode and Power off Yes, but not much else unfortunately.
If I select Recovery mode I don't go to the screen with the blue buttons from twrp.

What you need to understand is that twrp will not stick after you flash it. This device does not have a recovery partition and that's why you replace the boot partition with twrp and while you're in twrp you need to flash the boot.img back and whatever mods on top of that such as kernel etc.. If you flash a rom then it will replace the twrp with the boot.img found in the rom zip.
So now we need the computer to recognize you device. Could you unplug the cable and change the usb port on you computer. connect your phone while you're in the bootloader menu where it says start on the top.
The use use fastboot command: fastboot devices
See if the computer recognizes you device.

Root & TWRP!

Note: I am no expert at this. I used this to get TWRP and root, but it there is no guarentee it won't brick your phone. Only do this if you know what your doing. Before you start you must have an unlocked bootloader, which will delete all your data. Here's the instructions (If you need help, feel free to post a comment):
Download Magisk's installer zip on your phone from https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 (Google Pay only works with Magisk v19.0+)
Download arter97's kernel .img to your PC. This kernel currently is the only reliable way to get TWRP. https://forum.xda-developers.com/razer-phone-2/development/arter97-kernel-razer-phone-2-t3914996
Reboot your phone into bootloader mode (Turn off then back on while holding vol down).
Make sure your phone is recognized by Windows before proceeding. Follow this guide to setup the proper drivers and fastboot.
Flash arter97's kernel by running
Code:
fastboot flash boot arter97-kernel-*.img
If you run into any issues, then you will probably need to specify the slot to flash. Reboot back into your system.
Turn on Android Debugging and run
Code:
adb shell getprop ro.boot.slot_suffix
and make note if the output is _a or _b
Reboot back into bootloader
If _a use
Code:
fastboot flash boot_a arter97-kernel-*.img
if _b use
Code:
fastboot flash boot_b arter97-kernel-*.img
Reboot to recovery (either through bootloader mode or hold vol up while rebooting).
Install the Magisk .zip from TWRP.
Be amazed by the possibilities.
Old instructions (Should always work to get root):
Download the factory image from here: https://developer.razer.com/razer-phone-dev-tools/
Extract and copy the boot.img file to your device
Download and install Magisk Manager. If you have an SD card make sure it's installed on your internal storage, not the SD card.
Tap install, select Patch Boot Image File, and select the boot.img (If using the default file manager click the overflow menu and show internal storage)
Copy the patched_boot.img back over to your PC
Flash the patched_boot.img to your device via fastboot (Turn off then back on while holding vol down) and run
Code:
fastboot flash boot patched_boot.img
.
If you run into any issues, then you will need to specify the slot to flash.
Turn on Android Debugging and run
Code:
adb shell getprop ro.boot.slot_suffix
and make note if the output is _a or _b
Reboot back into bootloader
If _a use
Code:
fastboot flash boot_a patched_boot.img
if _b use
Code:
fastboot flash boot_b patched_boot.img
Reboot, and open up magisk manager to confirm everything is working. After an OTA update you may have to re-apply due to it using a different slot.
Note: the phone wasn't properly recognized by my computer when in bootloader mode so I had to install the Google adb drivers and manually set the driver used to Google Bootloader Interface (or something like that)
I found you needed to specify boot_a or boot_b specifically as the bootloader tended to mess up the suffix(it tried "bootb_b"????). So I had to first run "fastboot getvar all" to check the current slot.
I also found the commands are executed much more reliably if you enter the command first and press enter so fastboot goes into the "waiting for device" state and then boot into the bootloader and afterwards plug in the cable so fastboot executes the command as soon as it connects.
figured itd be as easy as that. this will be my first up to date device in years, att sending it to me in the mail. should get it by the 6th . but glad to see theres root! hopefully lineage to follow <3

Flash the patched_boot.img to your device via fastboot (Turn off then back on while holding vol down and run `fastboot flash boot patched_boot.img`.
Reboot, and open up magisk manager to confirm everything is working.
Note: the phone wasn't properly recognized by my computer so I had to install the Google adb drivers and manually set the driver to Google Bootloader interface (or something like that)
I also tried to install some Android Pie GSIs, but none of them worked.

Does this destroy all data? Do I need to unlock bootloader? Does it matter where I place the boot.img on my device?

Interesting. The bootloader isn't exactly what I'd call a masterpiece of coding (weird cause I still maintain the ROM is excellent) so it might have just been a momentary glitch.

Yes, yes and not really (you get a file chooser so you just need to locate it)
I updated the post a bit with instructions on how to flash to a specific slot.
Tonight I'm going to try compiling TWRP for the first time ever (unless someone beats me to in). Wish me luck!

Good luck it's a easier process compare to years ago. I would do it but I have no need for root or custom recovery. If you fail on the TWRP I will do it in time for people.
Is this working on the AT&T version of this phone? Or would you need to flash the global firmware in order for this to work? Looking to upgrade to this phone and I want to be sure I can get root. The rest looks to be coming fairly quickly.

I see the separate firmware. I'm only asking because of past shadyness from AT&T trying to tell manufacturers what to do. Years ago on my Xperia x10, if on AT&T firmware, you needed to flash the global generic firmware to get around their crap.

With the release of the factory images we can achieve root via Magisk boot image patching. Note: I am no expert at this. I used this to achieve root, but it there is no guarentee it won't brick your phone. Only do this if you know what your doing. Before you start you must have an unlocked bootloader, which will delete all your data. Here's the instructions (If you need help, feel free to post a comment):
Download the factory image from here: https://developer.razer.com/razer-phone-dev-tools/
Extract and copy the boot.img file to your device
Download and install Magisk Manager. If you have an SD card make sure it's installed on your internal storage, not the SD card.
Tap install, select Patch Boot Image File, and select the boot.img (If using the default file manager click the overflow menu and show internal storage)
Copy the patched_boot.img back over to your PC
Flash the patched_boot.img to your device via fastboot (Turn off then back on while holding vol down) and run
Code:
fastboot flash boot patched_boot.img
.
If you run into any issues, then you will need to specify the slot to flash.
Turn on Android Debugging and run
Code:
adb shell getprop ro.boot.slot_suffix
and make note if the output is _a or _b
Reboot back into bootloader
If _a use
Code:
fastboot flash boot_a patched_boot.img
if _b use
Code:
fastboot flash boot_b patched_boot.img
Reboot, and open up magisk manager to confirm everything is working. After an OTA update you may have to re-apply due to it using a different slot.
Note: the phone wasn't properly recognized by my computer so I had to install the Google adb drivers and manually set the driver to Google Bootloader interface (or something like that)
I also tried to install some Android Pie GSIs, but none of them worked.

Would this procedure be the same as far as mac/win?
I understand all of that, I am simply asking if someone has tried this with the AT&T variant yet. I want to know before I go order this phone.
I love a rooted phone, but as far as I know, if you unlock the bootloader, Netflix will no longer work in HD mode. To me, this is a deal-breaker. If anyone knows about a work-around, I'd love to know.
Razer phone 2 root
so im kinda new to rooting this type of phone and to the android boot scheme in general. i have a razer phone 2 and have attempted (febaly) to root it using this meathod. after installing the google adb drivers i was unable to see the device from my pc when it was in fastboot and unable to send commands, after installing the drivers again with windows update it ran even though no device was detected with this message
">fastboot flash boot patched_boot.img
Sending 'boot_b' (19268 KB) OKAY [ 0.523s]
Writing 'boot_b' OKAY [ 0.179s]
Finished. Total time: 0.718s"
it then blackscreened, i then tried a factory reset from recovery, and it is now in a bootloop... any advice?
update: no longer in boot loop but now is full blackscreen after a glitchy install screen

Since it's already wiped the easiest way to fix it is to probably flash the full factory image. Did you happen to update to the MR2 update prior to following this guide? Doing this on MR2 will soft brick. Not entirely sure in what way, but I assume it would be similar to what you experienced. If you were still on MR0 you can actually just fastboot flash the original kernel image to fix it. I just finished rooting MR2 so I'll post that next

Adb and fastboot are separate things. You should only need download mode and fastboot. What are you trying to use ADB for? If in doubt, the guide on Razer's website should be quite sufficient
EDIT: You can get to download mode by holding Vol Down and Power Button while the device is off. You can force reboot by holding down power for approx 15s as well

Can't install TWRP on OP6T

Hi - I am trying to reinstall TWRP on my OP6T after upgrading to OOS 10.3.0.
I am running Minimal ADB and Fastboot v1.4.3 on my Win10 PC. I have connected my phone to my PC, and entered Fastboot mode. The OP6T is detected when I do a fastboot devices command.
Next, I try doing a temporary Recovery Mode boot into TWRP with a fastboot boot twrp-3.3.1-1-fajita.img command. This is where I run into a problem ... While the Minimal ADB and Fastboot window says that the TWRP image was sent to the OP6T, I am still stuck on the Fastboot screen, and the phone is locked up and doesn't reboot the image.
What is going wrong?

Thanks, @jp0469! This helps a lot!
Just to be clear (and to get to a successful conclusion without a bricked phone), I won't be installing a TWRP installer ZIP file after booting into this TWRP image (The old style method), but instead installing the same TWRP IMG file as a "Recovery RAM Disk", correct?

Need a little more info before you proceed.
I know you said that you're currently on Android 10.3.0
Are you rooted with Magisk? If not, are you planning on rooting?

I was rooted with Magisk, but that got lost when I did the 10.3.0 update. Definitely planning on TWRPing and rooting again, as long as it's safe.

Once booted in twrp via fastboot flash the installer zip. It has always worked and will always. Always latest version. And flash Magisk after.

Put the latest Magisk zip and TWRP installer (zip file) on your phone's internal memory if you don't already have them there. Now you can fastboot boot the TWRP img file (Q version). Next flash the TWRP zip to permanently install TWRP into recovery. Reboot back to recovery to make sure it worked and then flash Magisk to re-gain root.
Reboot
Thanks, guys - The only reason I asked about the alternate "RAM Disk" method was because it was listed as the installation method by the developer on the link that @jp0469 provided earlier.
I'll try the old-fashioned method, since y'all say that it works OK.

I always install the latest directly from Google. There is a link on this page to the latest version of Windows ADB and Fastboot. Just unzip the file you download into a directory of your choice.
Everytime I try to boot twrp It says waiting on device. What's that mean

Hey I am running Android 10.3.7 and am having the same problem, I tried unofficial twrp linked abouve and still stuck on fastboot screen, I think I'm using abd 1.43, if twrp doesn't work is there an alternative? I'm newish to rooting I've rooted other phones but that was back in the good old days where it wasn't complicated. I am running a T-Mobile phone converted to international with bootloader unlocked

Trying to flash TWRP but no success (stuck on Fastboot mode)

I have been on a journey trying to go back to my T-Mobile OnePlus 6T back as my daily driver but the official updates killed the device for me. I have been successful in flashing it to the international version and now the device is on A9. I am trying to get it updated to A10 but in order do that (does not take OTA updates or can not flash within the updates app) I have to flash in recovery. Right now it is on stock recovery so I am trying to flash TWRP.
The problem is now that everytime I run the command " fastboot boot IMAGENAME.img" the phone restarts (as expected) and boots into fastboot but stays stuck in the Fastboot Mode screen.
I tried different TWRP images (older and the most current version per https://dl.twrp.me/fajita/ ) but I keep getting stuck in the Fastboot Mode screen. The last thing I was able to do without issues was unlock bootloader using fastboot.
I just need to be able to flash TWRP on the phone so I can still the final stock image so I can go back to using it as my DD.
EDIT: Disregard everything I fixed it. mods, please delete thread.
EDITR 2: Disregard that last edit lol Yeah I still need help. I am now tryingto flash twrp on a second 6T and the issue described above still applies.
You can try this version. Also try unplugging the USB after it reboots. You aren't getting any crash dump screen? So it should be working.

Tried your image and still same result. I am running following command
Code:
fastboot boot TWRP-3.6.1_11-OP6xT.img
The command window outputs the following
Code:
Sending 'boot.img' (34964 KB) OKAY [ 0.747s]
Booting OKAY [ 0.092s]
Finished. Total time: 0.860s
The phone then reboots into Fastboot Mode logo and stays stuck there. I even tried unplugging the USB after it reboots as well.
I even tried using the flash command instead of boot but no success.
How about fastboot boot recovery? Should be able to get into recovery somehow. Doing fastboot flash of twrp will mess up your boot partition but either way you still should be able to get into recovery somehow. There is the msm recovery tool you can use as last resort but it will relock your bootloader
Actually fastboot doesn't let you use boot recovery command I don't think. Only adb. But once you are in fastboot can't you choose to reboot recovery with volume keys?

When I am in fastboot mode, yes I can choose recovery but it takes me to the stock recovery. I do not have a option to flash any zip files there
Maybe you need a twrp for Android 9 since that's what you are on. But fastboot boot twrp should just take you there. Either have to find one that works or go msm route. Maybe windows not reading it correctly also. You using CMD or PowerShell?
