[Q] Error when trying to go back to stock via fastboot method

So i kind of got a situation here , i originally wanted to be rooted and have my nexus 6 non encrypted so i had unlocked and rooted my phone. After i ran the "./fastboot erase userdata" command i flashed the custom recovery again and booted into it. From there i thought i would be able to "./adb sideload" a stock custom rom non encrypted but for some reason i was having difficulty running that command. My laptop was not seeing the phone, so after about 30 min of playing around with it trying to get it to work i figured id just start over fresh. From this point i dont have an OS installed so i knew i would have to download the appropriate files for the nexus 6 so i did. I tried both methods, the "./flash-all.sh" command and flashing everything one by one rebooting the bootloader in between flashes and still kept getting this same error
fastboot(1561,0xa04aa1d4) malloc: *** mach_vm_map(size=1681293312) failed (error code=3)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
failed to allocate 1679613116 bytes
error: update package missing system.img
and now im stuck in fastboot mode at least, but cannot revert back to stock unless im missing something here. Can someone help please

it looks like the script is looking for a file that is not in the proper directory
the flash all script has never worked for me I have always had to manually flash the images.
looks like you are on a mac since you are using the ./with the command
follow the directions below and you should get back to stock
since you are already in bootloader mode
Download the required factory image files to your computer and extract them
Create an empty directory. All of the files that are required, need to be in one (i.e., the same) directory. It does not matter what it is called, but all the files need to be in there, with NO subfolders. EVERYTHING needs to be extracted into this one directory; (it is easier this way)
Download the version of Android you want to your new directory. Make sure you are using a nexus 6 image.
Extract the files from within the .tgz file which you downloaded in step 3 using 7-zip, not WinZip or WinRAR or whatever.
Make sure you have extracted ALL the files (including extracting any files in any archives inside the .tgz file). You should have six (6) files ending with .img in the directory you created in step 1. The other files you extracted from the .tgz are not necessary;
Open a command prompt in the same directory (i.e., make sure you are in the same directory as your files are located). You can hold the shift key when you are in the folder in Windows explorer and right-click in a blank spot and it will open a command prompt. In Ubuntu or MAC just cd to the directory.
Type in the commands into the command prompt
Make sure your computer recognizes your device by typing: fastboot devices
Flash the bootloader: fastboot flash bootloader bootloader-some-description-number.img
Reboot: fastboot reboot-bootloader
Flash the radio: fastboot flash radio radio-some-description-number.img
Reboot: fastboot reboot-bootloader
Flash the system partition: fastboot flash system system.img
Flash the data partition: fastboot flash userdata userdata.img
Flash the kernel/ramdisk: fastboot flash boot boot.img
Flash the recovery partition: fastboot flash recovery recovery.img
Erase the cache partition: fastboot format cache
Reboot: fastboot reboot
Done! The first boot will likely take quite a bit longer than you are used to, as Android builds the cache.
Now you have a fully stock image on your device. The only thing that is different from out-of-the-box condition is that your bootloader is unlocked.
No you can root or decrypt. Search for directions on the forum or the internet.

funny i just did this exact same thing like you instructed and was about to reply to this post saying i resolved it hahah. Thanks anyways though =), i dont understand why i was getting that though because i had every file in the same place

No worries glad you got it working

Also found out that you Dont do the ./fastboot erase userdate command because it puts 0s in and leaves the phone unbootable which was my root cause for my phone being stuck. Instead, after flashing the boot.IMG you do the ./fastboot partition userdata instead and it will do a factory reset and when booting it will not encrypt the phone.

And I was having the same issues executing the flash all command too until I opened the command in a text editor and for every command put the "./" in front and was able to execute it but this is the first time I've gotten an error. My nexus5 worked with this command no problem

worked for me but still could not decrypt

Flash Lineage on top of "incompatible" data

I built lineageos myself a while ago, and now I want to return back to stock lineageos. It gives me "can not flash on top of incompatible data". I'm pretty sure data is fine and going to work. Does anyone know what I need to tweak in it so that it does flash?
Just to be clear here, wiping the data and starting from scratch is not an option
*UPDATE* found one method. Edit following file : `META-INF/com/google/android/updater-script` commenting out following line with "#" such as:
# run_program("/tmp/install/bin/otasigcheck.sh") != "31744" || abort("Can't install this package on top of incompatible data. Please try another package or run a factory reset");

How do edited this file inside the ZIP archive before flashing? Extract the file via 7zip on Windows?
Edit: I deleted the two lines that included the text "Can't install this package on top of incompatible data. Please try another package or run a factory reset" directly in the 7zip internal text editor and was able to flash the ZIP afterwards via TWRP!

Unable to install any new Rom

I want to install new Roms on my phone.
I followed the guides in the forum and unlocked the bootloader, and installed TWRP. However, when I try to install the new roms like Resurrection Rom v6 or AospExtended v5.8 I get the following error:
Code:
E3004: This package is for device: titan, titan_umts, titan_udstv, titan_umtsd, titan_retaildsds, XT1068, XT1064, XT1063, XT1069; This device is .
[COLOR="Red"]Updater process ended with ERROR: 7
Error installing zip file '/sdcard/RR-o-V6.2.0-20180911-titan-Final.zip' .....[/COLOR]
I get a similar error for ASOP package too. except it complains about the bootloader:
Code:
E3004: This package supports booltloader(s): 0x4882, 0x4883,0x4886,0x4887; This device has bootloader
[COLOR="Red"]Updater process ended with ERROR: 7

.
My device model is: XT1068
And in the fastboot screen it says: 48.86
I would appreciate it if someone could guide me on how to resolve the issue.

You should've searched on YouTube. Unzip your rom using winrar, I don't remember the path but you have to remove the first two assert lines of the script with notepad++ and save it back and rezip the ROM.
Search on YouTube "how to fix error 7 in twrp". And follow his steps.
I just replace the default bootloader version present in script with the bootloader version it gave the error and it works.
Edit.
Or for avoiding any errors after rezipping the ROM. Just open the ROM zip through winrar and navigate to the script directory and hold n drag it outside and then delete the script present in that zip file and after editing the script using notepad++ hold n drag it back to the same directory. This way you'll not have to unzip and rezip.

Backup data from fastboot on Pixel 4XL

Hi, I am stuck in a bootloop with my pixel 4XL and can only access fastboot/adb. I want to pull my photos from the device before wiping it to factory settings but cannot figure out a way to do it. My bootloader is unlocked so figured it was possible somehow.
I cannot access files under sdcard using abd and changing the recovery image doesn't seem to work (I tried TWRP) using fastboot flash recovery, I get this error:
Writing 'recovery' FAILED (remote: 'No such file or directory')
I am guessing TWRP doesn't work because of Android 10
Have I got any options to try and backup my data?

TWRP doesn't work on devices that had Android 10 pre-installed due to a new partition scheme.
I would try dirty flashing a Google stock image of your current build. It should undo any kernel or Magisk changes for booting purposes.
Google images: https://developers.google.com/android/images#coral
Platform Tools: https://developer.android.com/studio/releases/platform-tools.html
Extract the image ZIP somewhere, extract platform-tools into that same folder. (fastboot/adb, the .bat file and the 2nd image-coral*.zip should all be in the same folder)
Edit the "flash-all.bat" file, line 23 should look like this: "fastboot update image-coral-qq2a.200405.005.zip" (remove the '-w' or your photos/data will be wiped!)
Make sure fastboot devices sees the phone, run the .bat and mostly ignore your phone screen until the .bat says it's done.
Dirty flashing may corrupt your face data which might later require a full factory reset. Normally you would delete the face data before dirty flashing.

Update after root pixel 4a 5g

Hi, I have unlock the boot loader and root my pixel 4a 5g in february update.
I don't understand how update it when new update comes ?
I can update it with Ota when comes in settings/System/Update ?
Or I do flash system image with fastboot and then flash the boot.img with Magisk to flash it in Fastboot mode ?
But I see : Flashing a new system image deletes all user data !!?
Before on Oneplus and later Xiaomi is more easy with Twrp. But now it's very complicated to update my freshly updated Pixel 4a 5g and Root
Please that it is the easiest procedure to update every month with Magisk installed. Previously I stopped all the Mods installed so as not to have a similar bootloop for Substartum .. Thank you
Thanks

Here's what I do:
- Download full factory image
- Unzip the archive
- There will be flash-all.bat (for Windows) and flash-all.sh (Linux) files created. You will need to edit the appropriate file to remove the -w flag on the "fastboot -w update image-bramble-rq1c.210205.006.zip" command near the bottom of the script.
- Within the archive you just unzipped, a directory will be created i.e. bramble-rq1c.210205.006 and within that there will be another zip file i.e. image-bramble-rq1c.210205.006. This zip file also needs to be uncompressed to extract the individual .img files including boot.img.
- Copy boot.img to your phone (Download directory is a good place)
- Flash the update using the edited flash-all script
- Once flashing is complete and the phone has rebooted, go into Magisk Manager and Install Magisk using the "select and patch a file" method. Navigate to the Downloads directory and select boot.img. Once complete, there will be a patched boot image named something like magisk_patched_bEKaK.img created in the Download directory. Copy that file back to your PC and then use fastboot to flash it to your phone i.e. "fastboot flash boot magisk_patched_bEKaK.img".
- Reboot phone and profit!
