i2097i · 3 Sept 2021, 18:49

this is the general gist of what I am doing:

adb reboot recovery && adb wait-for-recovery && adb shell "mount data" && adb shell "ls -la /data"

I haven't been able to get any adb commands to run on the device itself (adb devices works)

flohack · 3 Sept 2021, 19:07

@i2097i Just try to get adb shell working to get an interactive shell

i2097i · 3 Sept 2021, 19:08

@Flohack same issue - I'm going to factory restore this device and try again. I'll post my findings asap.

flohack · 3 Sept 2021, 19:23

@i2097i a simple adb shell should never get stuck, yes do that plz. And use an Android 9 image maybe to flash a few system partitions with the right version

i2097i · 3 Sept 2021, 20:23

@Flohack Yeah, the hanging of adb shell is likely on my end somehow. I am going to try a different cable along with rebuilding.

Yeah, I'll have to get these partitions cleaned up . I've been using the last Pie update PQ3A.190801.002 (5670241) to refresh.

flohack · 3 Sept 2021, 20:28

@i2097i I agree thats the one I would have taken too

@flohack I was able to boot into that image and list the data partition:

@flohack Ok perfect so data is empty currently. Can you please just boot into normal boot, and then try to do telnet 192.168.2.15 after lets say 20 secs on the Google logo? Thanks!

agates · 4 Sept 2021, 19:36

@flohack No change in behavior

flohack · 4 Sept 2021, 20:01

@agates ok can you check on your host what dmesg gives you, any mention of an RNDIS adapter coming up when booted normally?

flohack · 4 Sept 2021, 20:02

Oh and please see again in recovery if you can also mount system partition (mount /system_root could do it). And whats inside there...

@agates Okay so you got already some potential UT data in your system partition. Please wipe that too, so that data nd system are clean, then the boot should drop into a telnet session on 192.168.2.15

flohack · 5 Sept 2021, 18:30

@agates Oh and I forgot one important step, download vbmeta and dtbo image from here: http://twoot.bin.org.in/nextcloud/index.php/s/mzfmYJscqPyM2Bc

and then flash it with:

fastboot flash dtbo dtbo.img
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

Thats to ensure you have no error from verity during boot.

agates · 9 May 2021, 20:44

@flohack Hmmm, well now I'm in a boot loop. At least it's something different :). After the google logo I get a temporary black screen before it reboots.

And I still can't telnet

Both system and data are empty:

root@walleye:/ # ls -alh /data
total 0
drwxr-xr-x  2 root root 0 1970-01-01 00:00 .
drwxr-xr-x 24 root root 0 1972-09-20 23:41 ..

agates · 5 Sept 2021, 23:26

@flohack Oh also, same usb 3-2 dmesg entries as before.

flohack · 6 Sept 2021, 11:22

@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 · 6 Sept 2021, 17:18

@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 · 6 Sept 2021, 17:25

@agates ok bootloader is wrong, try Vol-Down
