Will keep you up to date, if a sound fix is incoming, or a gps fix for the Wiko Rainbow XSOP 6.1 ROM or the Resurrection Remix ROMs. Unfortunatly, this Wiko Rainbow ROM has that (old?) annoying crackeling sound bug, which I wasn't able to resolve for now. It seems to be a bit sloppy but it works.
I went for this Cyanogen CM 13 ROM mainly because it has GPS working. Heres how to install CM13 or any Android 6.0.1 Marshmallow ROM on your Samsung Galaxy S2 GT-i9100, you will need to repartition your system.Download & Step. Well there is Ken who is trying to keep people in line, but there are no changelogs and my offering for logs went to "look at post #XYZ". Ressurection 5.7.0 is mostly maintained at pd4.ru and XOSP isn't really backed up at XDA at all. So I turned my back on both projects for now. So I tryed around with Ressurection Remix 5.7.0 ROM but still. While I wasn't able to get GPS to run on XOSP 6.1 ( I did install the "GPS FIX" from the thread, but as the "WiFi fix )" it didn't have any impact) the mobile data seems to get corrupted sometimes when rebooting the phone. The reason: Neigther the XOSP ROM series nor the Ressurection Remix worked out for me when daily used. Then boot into recovery, make a Nandroid backup, wipe data, cache, flash CM13 ROM, flash Marshmallow Gapps and reboot your phone. CM13 is a popular custom ROM for Android devices which bring some features on your device which you won’t found on stock Android. For people who doesn’t like the Stock OS can Download and Install CM13 ROM for Moto X Play, that is based on latest Marshmallow 6.0.
See attached "Screenshot_Format_SDCard_Failure_Portable_Storage.png" picture for error message. The Cyanogen CM13 Marshmallow 6.0.1 MOD has been ported to the Wiko Rainbow recently.
This was expected and is normal for Android 6.0.1 in relation to Android 5.1.1.

for Android Marshmallow 6.0 (CM 13 Gapps) Gapps for Android Lollipop 5.1 (CM 12.1 Gapps). In general the Meticulus CyanogenMod 13 ROM seemed to function better in speed performance than the Meticulus Carbon LP 5.1.1 ROM for the devices. Gapps for Android Q 10 (LineageOS 17 Gapps) Gapps for Android Pie 9. I used the "" version with the fix-mtp patch. I finally had an opportunity to try this alpha build on my SGH-T599N.
