[Beta] Pixel 2 installer config

flohack

@agates Ok thats good, let it bootloop once and then press Vol-Up and hopefully it boots into recovery, then we finally might be able to get hold of a /sys/fs/pstore/console-ramoops log

agates

@flohack Hmm holding Volume Up during boot drops me into the bootloader with the following error message in yellow:

ERROR: Operation Denied

Nothing in /sys/fs/pstore/, either

Maybe I'm pressing Volume Up at the wrong time?

flohack

@agates ok bootloader is wrong, try Vol-Down

agates

@flohack Volume down just goes into the bootloader without the error

flohack

@agates Interesting. Okay we can try the following trick:

Flash twrp.img to boot partition
Issue fastboot boot boot.img that will make a one-time boot of our bootimage, then reboot into recovery. Thats my last resort to catch this.

@flohack OK, that didn't work. I decided to reflash android and re-flash ubports again for a fresh slate.

During the ubports installer while it was pushing files I decided to adb shell in and look for console-ramoops. To my surprise, it was there. No idea if it's useful or not.

Sorry for my absence. I currently only have a pixel 2 that is locked by the carrier and effectively useless for unlocking purposes. I was not aware that certain Pixel 2 devices had this. I will jump back in if I can get my hands on an unlock-able Pixel 2.

flohack

@i2097i Oh thats a pity. Yes, some carriers are mega-stupid, and Google happily jumped onto that. It should be forbidden by law.

@Flohack agree entirely. Hopefully it's a remnant of the past.

@flohack Any ideas how I might get past this "ERROR: Operation Denied" error? It seems that's what's preventing me from dropping into recovery after the kernel panic, right? and the bootloader erases pstore?

Walking in fresh to this.

I downgraded to Android 9.

On Linux Mint I opened the installer with

"ubports-installer --f /home/edi/Desktop/walleye.yml"

Install looks like it was successful, however the phone reboots to a white screen with the Google logo and an unlocked lock at the bottom.

Any suggestions?

Thanks all!

flohack

@flashylinux Well we took offline the installer config for walleye as it is not working currently. If you want to help testing thats fine, otherwise you will have to wait until we fix it at some point hopefully.

flohack

I removed the config now also from my first post. Sorry for the inconvenience!

FlashyLinux

@flohack I would love to help test! I have some experience with flashing and rooting. So I wouldn't be a complete noob haha.

How can I help?

flohack

@flashylinux Currently the problem is: Pixel 2 and Pixel 2 XL share the same device tree and kernel. In fact, they are almost identical. Yet we were not able to boot into UI or even telnet mode with the Pixel 2. Something gets stuck with our boot image.

What you can do is:

Wipe your device with TWRP (format userdata to remove encryption, wipe all other partitions as usual)
Flash this boot image: https://ci.ubports.com/job/UBportsCommunityPortsJenkinsCI/job/ubports%252Fcommunity-ports%252Fjenkins-ci%252Fwalleye-taimen/job/main/lastSuccessfulBuild/artifact/halium-boot_walleye.img into the active boot slot
Flash dtbo and vbmeta from here: https://twoot.bin.org.in/nextcloud/index.php/s/mzfmYJscqPyM2Bc
Note: vbmeta image needs to be flashed with fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
Reboot the device
Observe any activity on your USB on the host: Does any device appear after boot?
If not, try to flash twrp into boot, and then make a one-time boot of the boot image, thereby hopefully getting in some way a /sys/fs/pstore/console-ramoops to see whats going wrong

I never had such troubles with booting our images as on the Pixel 2

FlashyLinux

@flohack Okay I will get to work on that.

Also I didnt mention in my first post. And I didnt see this in the thread but after the install it boots to a "installing updates" screen with the little robot. Afterwards it reboots and gets stuck at the google screen.

I am able to get to recovery mode. Would the logs from the recovery mode be helpful? I tried to download them but unfortunately, while linux sees the phone I cant access it's file system, so I would have to provide the logs as screenshots.

@flohack said in [Beta] Pixel 2 installer config:

Flash dtbo and vbmeta from here: http://twoot.bin.org.in/nextcloud/index.php/apps/files/?dir=/porting/walleye%2C taimen/walleye&fileid=8312

When I click on this link it asks me to login to nextcloud.

@flashylinux Sorry this is the right link: https://twoot.bin.org.in/nextcloud/index.php/s/mzfmYJscqPyM2Bc

@flohack

Not so good news.

Instead of the being frozen on the boot screen. Now it boot loops.

Try #1
Steps
1. Wiped everything using TWRP
2. Flashed boot with “halium-boot_walleye.img”
3. Flashed dtbo with “dtbo.img”
4. Flashed vbmeta with “vbmeta.img” using fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
5. Rebooted device

Result – Boot loops

Try #2
Steps
1. Flashed boot with “twrp-3.3.0-0-walleye.img”
2. One time booted “halium-boot_walleye.img”

Result – This booted and then restarted and went into TWRP

I am able to see the device when I boot into TWRP though. Not sure if this is helpful or not.

flohack

@flashylinux Ok can you check after it bootloops if there is anything in /sys/fs/pstore?
