[RECOVERY][TWRP][dragon]

[followmsi]

April 1, 2017 .. and it's not an April Fools' Day Joke --> TWRP for Pixel C is official now !

https://twrp.me/google/googlepixelc.html

I would like to continue this thread for publishing test builds and other troubleshooting.
Once the changes are stable and tested I will merge them into TeamWin github for the next official build.

Known issues:
- FBE (file based encryption) is not working correctly, pls use FDE (full disk encryption) instead.

fwtool
The "fix fastboot" advanced menu item has been removed as it's not part of the official TWRP sources.
The fwtool is still existing (/sbin/fwtool) - only the menu item has gone.
If you need the fwtool, to fix fastboot, you can use it like before, but now you have to type the command into terminal inside TWRP.
For more details, pls have a look here .. http://forum.xda-developers.com/showpost.php?p=64777133&postcount=96

Installation:
Please install the new version from your current TWRP.
Pls make a "reboot to recovery" once you have installed the new version.
Of course you can install it via fastboot too.

Well done to both you and NYChitman!

I have noticed that when I go to make a backup, it finishes but is unable to unmount partitions after the backup saying that it is busy. If I reboot I am able to mount and unmount properly

Thanks for the feedback ..

Did you install something before .. maybe still mounted from before ?
Or you just made the backup only ?

Which partitions did you backup ? .. system as well .. or just data ?

Pls post recovery.log on pastebin.com .. helps a lot !

Thanks

Backed up system, data, vendor, etc.

Made a twrp backup before wiping to install new rom

System partition locks up and is unable to be wiped or flashed over until I reboot recovery

It´s always system which is complaining .. no other partitions, correct ?

Thanks ... will have a look.

 

[DarthDestroyeis]

Yup... just the system partition.

Hey. I'm back. Considering taking the risk and installing TWRP again. Will I still be able to take OTAs? No, right?

 

[ilpolpi65]

N4 + Update.ZIP_PixelC_Ryu_NPD56N-system-vendor.zip (flashed via fastboot) +TWRP_dragon_3.0.2-0_v16.img.

loop boot recovery..I tried everything but no chance to boot into system again

You did flash system-vendor update.zip via fastboot ?
No good idea.

The kernel and the TWRP are fine to flash via fastboot, but not the system.img and vendor.img.
Like written on first page of the updatr.zip thread.

Pls install the package via TWRP.
Or use unmodified stock image from Google for fastboot.

For recovery bootloop I know only "fastboot reboot".
I had the bootloop once myself, as I still was on M, but the command did help me.

I am not the OTA User
As I know, the tool "flashfire" from Chainfire should handle the whole OTA process smoothly.

The Update.zip packages I do anyway, because I am used to it .. over the years.
Did this for Nexus Flo ... Nexus 10 as well.
For Pixel C I just publish them, because nobody as else is doing it.
Look in Flo and manta xda .. They have these packages too, done by others.

Because of all the problems with OTA .. in the past ..and still today.

Today we have systemless root and regular OTA...times are changing.

Maybe it's time for something like flashfire in the next time ..

 

[ilpolpi65]

sorry I made a typo :
I meant Update.ZIP_PixelC_Ryu_NPD56N-kernel-dragon.zip ( I extracted boot.img)

This should work .. the boot.img is just stock.

Were you rooted and decrypted before?
You did install SuperSu afterwards ?

And 'fastboot reboot' did not help either ?

People have reported they had to go back to M to be able to boot again.
There was one recovery bootloop with stock recovery as well ,

Maybe you try another kernel (boot.img) too ?
A fresh one .. below from the stock kernel

Strange issue .. for me not reproducable at all!

Sorry, can't help you better ..

Yup... just the system partition.
