Nexus 4 / Nexus 7 CrossUpgrade from Cyanogenmod to Lineage OS

EDIT: Experimental Builds were deleted now, as initial stated by LineageOS Team in this post. CrossUpgrade is not possible anymore, best bet would be to wipe the device and start from scratch. So just skip the second step with EXP Image and WIPE EVERYTHING in TWRP and install the latest nightly. Please also stay alert on bugs which are included in LineageOS. This link will give you access to the unresolved section of the Nexus 4 / Mako device, while this link will give you access to the same for the Nexus 7 2013 Wifi / flo :). Also, you can find the latest changes for mako here and for flo here.

As CyanogenMod ended their services - and Lineage OS took over, we need to cross-upgrade to the new system.

0.) Basic idea:
To upgrade to Lineage OS, they setup an so called experimental image. This exp image exists soley for the reason of migrating old CM installations to LOS installations. An really ugly-nag-screen will remind you of that. So the upgrade path will be: CM -> LOS Exp -> LOS Nightly. Also, you need to upgrade to the correct version. I.e. LOS does supply Nexus 7 LOS 14.1 images, so you need to upgrade your Nexus 7 first to CM 14.1, then install the LOS Exp 14.1, then the LOS Nightly 14.1

1.) Nexus 4 (mako)
- Install latest TWRP Version: https://twrp.me/devices/lgnexus4.html
- Make sure your device is on CM 14.1, if not, upgrade via: https://download.cyanogenmod.org/?device=mako
- Download LOS 14.1 Exp and install via TWRP (clean caches!) and reboot: https://download.lineageos.org/mako
- Download LOS 14.1 Nightly and install via TWRP (clean caches!): https://download.lineageos.org/mako

2.) Nexus 7 2013 Wifi (flo)
- Install latest TWRP Version: https://twrp.me/devices/asusnexus72013wifi.html
- Make sure your device is on CM 14.1, if not, upgrade via: https://download.cyanogenmod.org/?device=flo
- Download LOS 14.1 Exp and install via TWRP (clean caches!) and reboot: https://download.lineageos.org/flo
- Download LOS 14.1 Nightly and install via TWRP (clean caches!): https://download.lineageos.org/flo

And thats it! 🙂

More Infos needed? Just check out this older blog entry - you can use 2) and 3) but please do not delete anything except caches on 3) - and you do not need to flash GAPPS - as we want to upgrade, not reinstall from scratch 🙂

[Google Music] Or: How do I get all my music online?

I appreciate art and I love music. And I just can't get enough of it: I really love to listen to my collection on "near all devices": On the Netbook while doing work at the University, on the Tablet while sitting on the couch or on my Phone - while running or commuting. That said, there is always the little and persistent problem of synchronizing data.

Google solved that problem by starting "Google Music": You can upload 20.000 Songs from your collection and listen to them - again and again - for free. Awesome!

But before you rush out and start getting your uplink glowing - let me share  two "words of advice":

1.) Clean your collection and tags. Yeah, you saw that comming and you hate it. Everyone does. But it is the only way to get fun out of your collection. Don't try to upload and correct that stuff later. It just won't work and will frustrate you. So do yourself a favor and work out that little errors and problems. Get in some cover pictures, too. MP3tag ( http://www.mp3tag.de/ ) was my tool of choice and works awesome. While using the latest WinAMP to convert Audiofiles from foreign Formats to MP3 - and to look for "a little too strange songs" via the Autotagger - you will get these files ordered in reasonable time.

2.) Your only way to upload your music to Google is by using the Music Manager Tool. It seems straight forward and easy - but it is kind of buggy. Look out for "not uploaded" files by checking files from your HDD against your Google Music Account. Music Manager tends to "overlook" files and can't be pushed to upload certain missing files by adding another folder with the same, missing files. The only thing that is working out is browising to C:\Users\%username%\AppData\Local\Google\MusicManager and deleting the files there [Win 7 Path]. Especially the Database / db File. After restarting Music Manager, the tool will reindex your files and upload missing ones. If "Johnfail" wouldn't had found this Workaround, I would still be sitting ducks. Here is the original post: http://johnfail.wordpress.com/2012/01/12/more-google-music-upload-failure/

Thanks a lot :)!

Other than that - enjoy your music! 🙂
