- Version of /e/OS: 2.7 u
I recently bought the smartphone Google Pixel 8 Pro. Android 14 (March period) was installed on it. When trying to install /e/os v2.7 (husky) according to the instructions Install /e/OS on a Google Pixel 8 Pro - “husky”, my first problem was that the “Enable OEM unlock” in the Developer options was grayed out. A quick internet search revealed that updating to the latest Android version fixes the problem. The /e/OS-instructions contain the tip that:
Before installing /e/OS on the Google Pixel 8 Pro husky for the first time, install the latest stock OS version 14 build on the device
I asked myself how I could install exactly the latest stock OS version 14 build on the device. I could find no further reference to this in the above mentioned /e/OS-Instruction. So I used the update function in Android, which installed the latest Android 15 version.
After than I followed the further instructions and everything worked quite well so far…
After I had unlocked the bootloader and flashed the additional partitions, the next hurdle for me was to switch to recovery mode. After input
entering fastboot --set-active=a
I switched to boot__a and then I also entered recovery mode.
I carried out the factory reset together with the format data.
When executing adb sideload <downloaded_file_name>.zip, the program aborted at 47% with the following error message:
Error: recovery : Signature verification failed
Error: recovery : error: 21
Install from ADB completed with status 2.
Installation aborted
I have already published this post here. They explained to me there that the Android 15 update was the cause of this error and that I could fix it by installing a Google factory image.
I wondered if it would be that easy as I had changed the status of the smartphone by following the steps in the /e/os-instructions (“Flashing additional partitions” and “Installing a custom recovery using fastboot”). Unfortunately, I didn’t get any answers to these questions. So I just tried it out withe the latest stock OS version 14 build (14.0.0 (AP2A.240905.003, Sep 2024) for “husky” and Pixel 8 Pro).
The flashing of the factory image was not successful either. The command
fastboot --slot=other flash bootloader bootloader-husky-ripcurrent-14.5-12100691.img
was remarkably fast - only 0.6 sec. Afterwards I noticed that the following warning at the beginning:
Warning: skip copying bootloader_b image avb footer (bootloader_b partition size: 0, bootloader_b image size: 18118264).
After I entered the commands “fastboot set_active other” and “ fastboot reboot bootloade” twice and then rebooted, only a white Google still image appeared.
I asked myself if the warning significant? And if so, how do I get more space on bootloader_b or should I switch to bootloader_a?
I then tried it out with the latest Android 15 version. The same error messages appeared. So I think I was right with my initial concerns that you can’t easily play a factory image on the smartphone after you’ve already completed the steps in the /e/OS instructions: “Flashing additional partitions” and “Installing a custom recovery using fastboot” plus the failed attempt “to install /e/OS using /e/OS recovery”.
No one could help me in the previous post and I was told to try here.
I wonder where I did something wrong or thought wrong? What do I need to know or what can I do to install /e/OS on my smartphone from its current state?
Thank you very much in advance
