I will be installing the latest image offered for /e/ from the repository on a Google Pixel 5.0 and I will follow these instructions: https://doc.e.foundation/devices/sailfish/install
My two questions are:
To 1: downgrade from 10 to 9 should work
To 2: you can’t lock the bootloader after flashing any custom rom
Thanks for the info.
I tried to downgrade from Android 10 to 9 with no luck.
OTA images from Google fail as expected. Wrong dates.
Using factory images and unlocking the bootloader I used the flash-all.sh (I’m using Linux) and this exited with error:
mke2fs 1.44.1 (24-Mar-2018)
/tmp/TemporaryFile-lCpyRi: Unimplemented ext2 library function while setting up superblock
/usr/lib/android-sdk/platform-tools/mke2fs failed with status 1
mke2fs failed: 1
error: Cannot generate image for userdata
I went back and started from scratch and sideloaded another OTA image that had been released in December 2019 and my Pixel was October 2019 but I was not offered the December update on my phone. This should have reset everything I might have changed.
Any suggestions?
It could be an issue from fastboot you have installed. Is it from your distro or from Google Android Studio. ? You should install the latest from Android Studio
I am using fastboot and adb version 1:8.1.0+r23-5~18.04 from Ubuntu apt repositories. I used thes to flash a Samsung S6 Edge and a Nexus 5x
Android Debug Bridge version 1.0.39
Version 1:8.1.0+r23-5~18.04
Installed as /usr/lib/android-sdk/platform-tools/adb
I installed the complete Android Studio 2 times on my main computer and once on a different computer.
If I install Android Studio I do not have access to adb or fastboot and I understand adb and fast boot are included with Studio so maybe my installation is wrong.
Thanks for the help but this is over my head. I have flashed /e/ on a Samsung S6 edge and a nexus 5x so I’ll just stick to those for now.
Here is the entire output if anyone cares to follow up:

Thanks for the pointer. I did read those instructions when I was doing this. I also read a few others.
Sorry, I’m now a little confused. What are you trying to do? Flashing stock rom or eOS ?
flash-all.sh is for stock rom, as for as I know from my MI devices.
When I’m reading the
archive does not contain ‘boot.sig’
I think you stock rom zip is not the right one for your device.
Could you share a link from where you have this zip ?
I am trying to downgrade from Android 10 to 9 on a Google Pixel 5.0. I have tried 2 different images from the Android 9 series.
Images and instructions from here: https://developers.google.com/android/images#sailfish
Specifically images: 9.00 (PQ3A.190801.002, Aug 2019) and 9.0.0 (PQ2A.190305.002, Mar 2019)
I have read other instructions as well including the one posted above.
I am going to keep using my S6 Edge for now so don’t spend much time on it. When I get back to my country in March and I have more time I’ll work on it again or buy a different phone.
Solved… Maybe
I had a few minutes and thought that maybe I could boot into TWRP and install an Android OTA v9 this way.
I booted the Pixel into TWRP for sailfish and followed the /e/ documentation instructions to install /e/. I could Format Data and then I could Wipe System but not cache. There was no option to check for cache. I went ahead and completed the Wipe portion and then went to Advanced and selected ADB Sideload. Once the phone was waiting for the file I sent an OTA Android 9 to flash. This completed and I rebooted to Google Android 9. (there was not mention of a cache partition missing)
Once I had Android 9 installed I rebooted into TWRP again and followed the instructions for installing /e/. Again there was no option to wipe a cache partition. I sent e-0.7-p* and when it finished the phone rebooted to /e/. There was a red letter warning of failing to write to the cache partition at the end of e-0.7-p* sideload.
Is the missing cache partition a problem? If so can it be fixed easily? (novice here)
I have internet connectivity with browser and email syncs. Calendar does not sync. I’ll look into the calendar problem later.
Edit: The installation instructions on LineageOS differ from what /e/ shows. lineage shows to wipe system only there is no mention of wiping cache.
The Pixel 5.0 is Redfin. The Pixel is Sailfish.
I think the “5.0” reference here is about the screen size (Pixel 1: sailfish: 5.0 screen), not the model.
Kind of a hijacking here, and maybe the question would be more appropriate in the “weekly updates topic”, but anyway: the Pixel 1 is definitively dropped out from future upgrades? In Lineage there is a 18.1 version available: LineageOS Downloads
