Upgrading Homebrew Channel

This guide upgrades the Homebrew Channel on your rooted TV to Test Build 0.8.0-test2.

Do I need this if I already have v0.7.3?

webOS 11 - apps that need root access may report that root is not available, even if homebrew says that root status is ok (fix).
webOS 7 and webOS 8 - fixes Parse Error: Header overflow when installing or updating apps from the homebrew TV app because GitHub now sends more than 8 KB in headers and nodejs on these webOS versions can't handle it. (fix)
webOS 1 - 3 - homebrew autostart doesn't work on these old webOS versions, so startup.sh doesn't run after the TV reboots and there is no SSH or Telnet (issue, fix).
webOS 4, 5, 6, 9, 10 - v0.7.3 is enough, you don't need to upgrade to 0.8.0-test2.

Prerequisites

Rooted TV. Non-rooted TVs are not covered in this guide (yet).
Enabled SSH Server checkbox in homebrew settings.
You need to be connected to the root shell of your TV. You can follow my other guide about installing and using webOS Dev Manager (or just connect via SSH root@TV_IP pass alpine). Then come back here.

Upgrade homebrew channel to 0.8.0-test2

To upgrade homebrew channel to 0.8.0-test2 we will copy paste few commands to the TV's root shell.

We are connected to the root shell

First download the new Homebrew Channel 0.8.0-test2 ipk file (this assumes your TV is online):

wget https://github.com/throwaway96/webos-homebrew-channel/releases/download/v0.8.0-test2/org.webosbrew.hbchannel_0.8.0_all.ipk

Updating Homebrew Channel from the terminal

Install the new homebrew channel 0.8.0-test2 ipk file:

luna-send-pub -i 'luna://com.webos.appInstallService/dev/install' '{"id":"com.ares.defaultName","ipkUrl":"/home/root/org.webosbrew.hbchannel_0.8.0_all.ipk","subscribe":true}'

Homebrew Channel update output in the terminal

After you see that is was installed (there is no change for 20 seconds), send CTRL+C to return back to the shell.

Stopping the Homebrew Channel update output with Ctrl+C

Elevate the Homebrew Channel service:

/media/developer/apps/usr/palm/services/org.webosbrew.hbchannel.service/elevate-service

And copy the startup script:

cp /media/developer/apps/usr/palm/services/org.webosbrew.hbchannel.service/startup.sh /var/lib/webosbrew/startup.sh

Copying the startup script in the terminal

Ve will now verify it. Open homebrew:

Homebrew Channel app tile on the webOS home screen

Go to homebrew settings

Homebrew Channel main screen with the settings gear in the top-right corner

Homebrew channel is now updated and root status says ok:

Then press the System reboot button and verify that the root is still ok
