[PORT] Ubuntu Touch for LG L90 Dual

peat_psuwit · Mar 16, 2015

Update 30 October 2016: I'm sorry for very long delay. Being a university student make my free time lower considerably. Anyway, new device tarball is released in stable and rc-proposed channel. This version mostly contains minor fixes, but more importantly, this includes fixes for some famous vulnerability, including the Quadrooter and dirty CoW vulnerabilities. Go to "System Settings" to get your update, or follow instructions below if you haven't update your phone since 9 January 2016.
I still ship experimental fixes in rc-proposed that may freeze your phone when the screen is off. If this matters to you, you may consider using stable channel for now, but that has pretty bad power consumption (but that still means about one day of light usage). Also, there is known bug about mobile network not usable on some network that affects all channels.
Oh, and for those stay on absolute bleeding edge on devel-proposed channel, I currently don't have enough time to test that. So, no release to devel-proposed just yet. Sorry!

Introduction
This is a port of Ubuntu touch to LG L90 Dual and all L90 models. (See below for tested devices.) Basic functionalities work, but there're still some rough edges all around. It's stable enough to use daily, and I personally use it on my phone every day. If you're tired of Android, you may want to give Ubuntu touch a try.

Tested device
This doesn't mean other devices aren't supported. If your device is labeled as "L90" (or can run Cyanogenmod for LG L90), you can give this a try.

LG L90 Dual (D410) (My device )

LG L90 D405n (single card) (Thanks, keturidu!)

LG Optimus L90 D415 (T-Mobile variant) (Thanks, JamesB3)

What's working/not working

Note that this is tested using rc-proposed channel.

Screen: Works

Touch: Works

Audio: Works

Screen rotation: Works

Vibration: Works

Camera: Stil picture works for both camera. But video recording doesn't work for the front camera.

Mobile Phone: Works for both SIM, but please see "Bugs and workarounds" below for info about 3G slot and data connection.

Wifi: Works

Video playback: Works

GPS: Works.*

Bluetooth: Works, but on/off doesn't.

*Do note that Wi-Fi-assisted location isn't available as ~~it's licensed for the official devices only~~.

How to install/upgrade

Code:
Installing for the first time (updated):

The easiest way to install it is using ubuntu-device-flash. All of your personal data will be deleted. Make sure you backup everything important before install.
You have to root your device and unlock device's bootloader. This forum has a good tutorial on that.
For rooting, I recommend http://xdaforums.com/lg-l90/general/guide-root-l90-varients-updates-t2928364. If that doesn't work, try http://xdaforums.com/showthread.php?t=2732311. This guide is guaranteed to work.
For unlocking bootloader, I recommend http://xdaforums.com/lg-l90/general/guide-guide-to-unlocking-bootloader-l90-t2852917
Also, you'll need an Ubuntu (virtual) machine.
If your device has been running Lolipop, you may have to flash Kitkat-based bootstack for your device (http://xdaforums.com/lg-l90/development/bootstack-kk-l-l90-t3118632). Make sure you know exact phone model (Dxxx__).

Follow the instruction for preparing your desktop in this link.

Select channel (see information about selection above). Don't download device tarball. The flashing software will get it for you.

Enable ADB for your device. I won't teach you here, but, again, this forum has a good tutorial about that.

Plug your device into your computer. Then, put the device in fastboot mode by running the following command:

Code:

adb shell su -c 'dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/boot bs=16 count=1' adb reboot

The first command will wipe the first 16 bytes of the boot partition. So, when the device reboot, it'll boot into fastboot mode as the boot partition is broken. Don't worry, it'll be flashed by Ubuntu Touch anyway.

When the device is in fastboot mode, run the following command:

Code:

sudo ubuntu-device-flash --server http://system-image.ubports.com/ touch --channel ubuntu-touch/{selected channel} --device w7 --bootstrap --wipe

There maybe some trouble flashing recovery. If that happen, re-plug the USB chord and try again. You'll see a lot of text and then purple recovery screen. At this point, the computer will push the files into your device. Don't unplug your USB chord until the device reboot again with big Ubuntu logo spinning. Wait until the device reboot into Ubuntu Touch, and, viola, Ubuntu Touch is installed!

Upgrading your device or switch channel (updated):
If you've updated your device with new instruction at least once (since 9 January 2016) and just want to update the device tarball, just go to "System settings" on your device to get your update. But if you've never updated with the new instruction, read on.

Enable developer mode on the device by going to System Settings > About this phone > Developer mode. If you don't have a passcode for your device, set it now by pressing Lock security. Then, enable developer mode by pressing at the check.

Plug your device into the computer, unlock your device (this is important) and run:

Code:

ubuntu-device-flash --server http://system-image.ubports.com/ touch --channel ubports-touch/15.04/stable

Don't unplug your USB chord until the device reboot again with big Ubuntu logo spinning.

Flash different (Android-based) recovery:

Ubuntu recovery can't be used to flash Android-recovery-format ZIP file. If you want to go back to Android using backed up file or ZIP file, you'll need custom Android-based recoveries, such as TWRP or CWM. You'll need raw disk image (IMG file) for this. Run the following command in terminal:

Code:

adb reboot recovery # wait for recovery to appear adb push {recovery image name}.img /cache adb shell dd if=/cache/{recovery image name}.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery adb reboot recovery

Download & Source code

You don't need to download device tarball manually anymore as flashing software will deals that for you. But if you want, you can download device-specific tarball using --download-only flag with ubuntu-device-flash. Be warned that you can't flash that image directly because updater in recovery image won't trust the signature.

Customization on the Android side can be found in the local manifest in this Github repository:

Change method to wait for Bluetooth config at startup.

Change grid unit size to 13px.

(rc-proposed only) Run init.zetaw.post-boot.sh when the phone finished booting. This'll make battery consumption a lot lower but will cause the phone to lock up sometimes. That's why I release this fix to rc-proposed channel only. If you can't bare with something like this, switch to stable channel.

28 April 2016

Add a workaround for NetworkManager, to fix Wi-Fi connectivity after mobile data is disconnected. The actual fix is preparing to land in rc-proposed soon, but until then, let's use this workaround.

17 March 2015:

Partially fix camera. It can take a still picture, but cannot record video.

Fix the problem about GPG signature properly. The hack is no longer needed.

Bugs and workarounds

Note that this list is based on rc-proposed channel and stable-based device tarball.

At boot, the device may freezes and restarts itself. ~~This is due to the Wi-Fi system and I'm investigating this issue.~~ This is due to fatal subsystem failure in the kernel. I've reduced possibility for Wi-FI subsystem (this is the most common failure), but this may still happen but at the lower rate.

If Wi-Fi list doesn't update during the day, turn Wi-Fi off and on.

Turning Wi-Fi on and off currently doesn't work. (Note that while you can turn Wi-Fi on-off in system settings, the Wi-Fi chip will be not turned off.)

If you're using rc-proposed channel, you may experience lockup when you're trying to wake the phone up from sleep. Currently, there's no fix yet, but if you can't live with it, use stable channel instead.

If you're using some mobile provider, your phone will not be able to detect SIM card. The fix is being developed. (If you're curious, it's about comunication between RILD and oFono and how your SIM card is programed.)

Fixed or disappeared problem:

~~Camera will stop working after you bring camera app from suspended state. Workaround: bring app back to suspend state and bring back again. This can be done by swiping from left edge.~~ This seems not be the case now.

Sometime, the device may seems freeze because an app is crash. This seems to be the problem in graphic subsystem. The system may becomes responsive again after seconds, but if it takes too long, just restart the phone. This seems not be the case now.

~~Sometime (at boot or sometime after), Wi-Fi stops working. This can be noticed by having Wi-Fi network list not updated.~~ Fixed by pseudo-on/off fix.

~~Second One or both SIM slots may stop working at some boot. Simple rebooting should fix it. You may have to reboot multiple times.~~ Seems to be disappear.

~~3G slot selection doesn't work when there's only 1 SIM card. Workaround: use another SIM slot.~~ (Fix released)

Data connection will work with only 1 of the slots (the one you most recently used before flashing Ubuntu touch. Don't worry, if you can't remember you van try them both). Workaround: put the SIM card with a data plan in another SIM slot. If you happened to have only 1 SIM and the slot that data works is different from the slot with 3G capability, I recommend you to temporary borrow another SIM card from your friend so that you can change 3G slot. change 2G slot in system settings. Fix accepted and released.

I will try it when I have the time. I have been waiting to try Ubuntu Touch

Question: Does this method of install wipe custom recovery?

This method will install Ubuntu's recovery before using that recovery to install Ubuntu Touch. So, yes, your custom recovery will be wiped.

I would love to test this out on my D415. Once you get mobile phone and wifi(because t-mobile's mobile data sucks here. I only get 2G xD ), Once those two things get solved i'll be happy to test. Also I think if you moved this thread over to the android development section you'll get more interest shown. I know Ubuntu isn't android but it's still technically development.

I'm working on mobile phone now and I promise that Wi-Fi will be the next.

Anyway, I cannot guarantee that it'll work on your phone, because I have only LG L90 Dual (D410). It may boot or it may not. I have no clue at all.
BTW, I don't know how to move the thread. Please tell me how.

That's great! I understand I just want to ask if I will have any way to get my device back to android if it doesn't boot?
And you could probably PM the moderators of the forum and get them to move it.

I'm a fan of ubuntu. Never heard much of the mobile version though. How much app is available on this platform or are Android apps also compartible?

There are a little over a thousand apps right now and its just an upcoming platform so it doesnt have good support yet. Android apps are not compatible and will not be officially compatible though someone will eventually change that.

Thanks. Is there any way I can browse through the list of apps and see? I also read somewhere that the apps for desktop version are compatible with that of the mobile version. How through is this?

https://uappexplorer.com/ is an unofficial app store. I know nothing about compatibility other than what Canonical has said. I have no experience using Touch. It would be awesome if Touch could be flashed by zip because I dont feel like f-ing up my only phone..

Has anyone tested this rom yet? I am curious how well it performs and of any bugs. I want to install it but I dont want to screw anything up

JamesB3 · Apr 11, 2015

Is there anyway to recover from this if it doesnt work? Or anyway to go back to android?

Is the developer still working on the project at all?

You can take a backup with CWM/TWRP before install. If the rom doesn't work, you can boot into recovery, flash CWM/TWRP back, and restore your android.
If in doubt, you can always install stock rom via KDZ file. Search this device's forum for instruction.

JamesB3 said:

I'm still working on it if the time permit. The latest update have working Wi-Fi now. Please, don't ask the question like this again, because porting an operating system is not an easy task.

Do i use Ubuntu's terminal to install?

BellaMay95 · Apr 12, 2015

Instructions for installing Ubuntu can be found here: https://developer.ubuntu.com/en/start/ubuntu-for-devices/installing-ubuntu-for-devices/.
Instructions for reverting back to android can be found here: https://developer.ubuntu.com/en/start/ubuntu-for-devices/reinstalling-android/.

I don't know if the installation instructions will vary at all since we have our own image instead of pulling from their repository....but I imagine it would be similar.

Hope that helps!

peat_psuwit · Apr 14, 2015

JamesB3 said:

Yes, you'll use terminal in Ubuntu to type those command. I'm not sure if ubuntu-device-flash is available on another Linux distro.

Most of installing instruction will apply here, just don't forget to specify device as generic and provide our device tarball. The parts that doesn't apply is about unlocking bootloader, because we actually can't do it that way. Instead, use instruction in this device's forum.
The reverting instructions can't be used here, as LG doesn't ship our device's ROM in that format. Instead, search this device's forum for instruction.

I tried to install but after install recovery it says that i´ve no space on the device

I guess you probably need to check free space on your computer. The phone probably have enough space to install this.
But if it still doesn't work, please copy full message printed on the terminal. The error should say if it happen on the phone or on the computer.
