Cannot load android system / 6a / 2026062300

popallo

hello,

my pixel 6a with 2026062300 doesnt boot any longer
"Cannot load Android system. Your data may be corrupt. if you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device"
i suspect the battery was low/empty when the update was running.

I tried sideloading via fast boot with the signed update packages:

2026062300 stable
2026062300 beta
2026062800 alpha

after rebooting i always get the same message
interesting fact: when i start a new sideloading process in fast boot it says "„in-progress update onoging" like it is not finished, the command line in platform tools though shows "Total xfer: 2.00x".

C:\Users\X\platform-tools>fastboot getvar current-slot
current-slot: b
Finished. Total time: 0.023s

C:\Users\X\platform-tools>fastboot getvar slot-successful:a
slot-successful:a: yes
Finished. Total time: 0.001s

C:\Users\X\platform-tools>fastboot getvar slot-successful:b
slot-successful:b: yes
Finished. Total time: 0.002s

C:\Users\X\platform-tools>fastboot getvar slot-unbootable:a
slot-unbootable:a: no
Finished. Total time: 0.002s

C:\Users\X\platform-tools>fastboot getvar slot-unbootable:b
slot-unbootable:b: no
Finished. Total time: 0.001s

C:\Users\X\platform-tools>fastboot getvar snapshot-update-status
snapshot-update-status: snapshotted
Finished. Total time: 0.017s

I cannot switch to the other boot slot because the boot loader is obviously locked.

Is there anyhing i can do to fix this without data loss?

thanks in advance

popallo i suspect the battery was low/empty when the update was running.

For future reference, System Updater can be set to download updates only while charging.

popallo snapshot-update-status: snapshotted

Hmmm. If the status were "merging", I would recommend: https://discuss.grapheneos.org/d/12814-fixing-the-your-device-is-corrupt-error-after-power-loss-during-system-update. But that may not help in this case.

Merging didn't work but i managed to cancel the "in progress update". After that when i tried to sideload 2026062300 stable it didn't work because it would have been a downgrade. I tried again with 800 and it did go through. Unfortunately after rebooting i have the same problem again.
