[Samsung Galaxy Nexus] drumst1x:
When I first came to 10.2 (from one of Tiny's older 10.1 linaro-optimized builds), I came over to Tiny's build (it had some other toolchain optimizations in it, and i've had luck with his builds/kernel on my phone in the past). When I did that, I did a full wipe (data, system, cache, dalvik). After flashing his 10.2, i switched over to the official nightlies to see if the data issues I was experiencing were due just to his builds, or to CM10.2 in general. I "half-dirty" flashed then (wiped system, cache, dalvik, but NOT data). Still had the data issues (this was early september).

Since then (and in general, any time I'm flashing), I have only wiped system/cache/dalvik (and not data). I do this every time regardless of if someone says it's not necessary, it doesn't hurt anything, just takes a few more minutes when flashing. As I'm having some other TiBu issues at the moment (not to get TOO off-topic, but i can't run a TiBu backup -- it doesn't give me the out-of-storage-space error everyone else has gotten, it simply stops running (no force close window or anything) after about 10-15 apps backed-up. Almost as if it runs out of memory or something. I've tried changing the backup path to legacy, no difference), I'm apprehensive to do a data wipe unless i absolutely have to.

- I haven't tried the build.prop edit (don't think I even saw that one actually, i'll go back and look through again to see if I can get any better results using it).

- I do reboot fairly often (normally due to running out of battery, though I must say DAMN does my battery last longer now that i'm on 3G only :) )

- I have tried the *22899 one time on a flash, and it seemed like it killed my APN value for a while (not really sure what that does, but it did eventually come back). I've read mixed things on doing a manual *22899 with these phones, some say that it can fry the sim card, and that it shouldn't be necessary at all with LTE..... i guess the jury is out though, because i certainly didn't fry my card or anything, as i can still get it working as long as i'm not going from cell to cell, but rather staying in one place.

I didn't realize that the *22899 would be necessary after every flash, so maybe I'll try the build.prop edits and the *22899 trick every flash and see if I have any better results. Thanks for this info, was very informative and helpful!

I do hear that this is running awesome on lots of people's phones, however (and I said this in an earlier post you must have missed) I've found that I've been getting MUCH better / smoother running with 10.2 than I ever did with 10.1 (granted, i wasn't on stable, i was on nightlies). 10.1 always seemed really laggy, and that is mostly gone with my new 10.2. Thanks for the heads-up though. This is a solution for lots of people, and if i can't get LTE working soon (whatever soon means), I may end up going back. Again, as stated above, i'm apprehensive as i'd want to do a full wipe to go to 10.1.3 stable, and since TiBu is borked for me, i'm trying NOT to do that. If TiBu was good for me, i'd probably have made the switch already, and just kept reading on here until people said "Yup, it's fixed with the latest nightly" .... one day ..... :)
