Yes, you can update via the Play Store and won't lose your addons or their settings.. That's how I went about mine. Of course, you have to backup your current Jarvis installation + apk, in case you have to revert. I'm able to get DD passthrough on Krypton and the audio - video sync I suffered with 17.0 is nonexistent on 17.1. Knocks on wood.

Note: If after the upgrade, Kodi refuses to launch and simply crashes all the time. You may want to delete the guisettings.xml, advancedsettings.xml (I had to do this for my installation...also deleted a conflicting addonsdb file.. Forgotten the exact file name) and confirm that the addons (especially skins) from Jarvis are confirmed compatible with Krypton. Otherwise, you'd have to go manually delete the offending addon or files, etc. You should only do this if you have intimate knowledge of your system and Kodi installation. Else, backup Jarvis.. Uninstall, install Krypton as new and setup from scratch. Might be easier than going through a troubleshooting process like I did. 

That's what I thought actually. Try to upgrade first and if it is acting up, I will start from scratch. Yeah, no worries I have Jarvis apk. Thanks for the tips!

Which box you going to update?

My 3 months old external hard_drive die on me. sent back to warranty just now. 

My own Docooler box.

let me guess... one of those "green, environmental" models?!

oic! no need to wait lor. Krypton v17.1 platform much nicer to use. 

Yes, been delaying for some time already.
I know the white box only accepts Jarvis.

WD 

Totally failed to detect

WD.. after many purchases, failures, warranty...

best one is ELEMENTS (made in thailand).
passport, passport ultra.. so-so (made in malaysia).
MYBOOK "green" is the worst.

If you want to update the white box. Use SPMC v16.4 from playstore. It's compatible with the latest SSL changes. 

I have a 3years old 4TB MyBook. Still going strong. All my photography work I back up there. 

All IT service dept said it will take 2-4weeks for replacement. confirmed hardware failure. 

Oh got it. Never thought of SPMC.
Still using Jarvis on that box.

Anyone using Trakt for managing watched show and/or add as collection?
it doesnt update at the other machine if i watched any shows in 1 device another device doesnt show as watched.
Already noticed this prob since like Kodi v13 ?? that time still with Genesis.

I doubt its account prob as my mom-in-law also same prob

Any other better (freeware) option to use?

SPMC is what Jarvis for Android should have been in the first place.. Can't blame the Kodi devs, as they have been asking for dedicated Android devs to come on board to make it better.. But so far, not so much success.. However, I can confirm that 17.1 is better and has been pretty smooth so far with my needs. Device dependent of course.. YMMV.. 

i didnt quite understand how quasar works...

like we select the tittle we want to watch, then select option to magnetize, then they will autosearch the torrent rite?
but seems like now downloading/ no downloading progress....
