[Galaxy S II General] unreal64:
the latest nightly (as reported by some users) contains bug fixes for the CWM recovery which could cause the erasing of internal/external. AFAIK the RC2 has it (as the fixes has been merged later).

I would like to share two experience i had with this ROM in the latest month.

ABOUT ALTERNATIVE KERNELs:

I know that i should not talk about it here, but i saw many times lot of people talking about alternative kernel which dramatically improves their battery life & perfomance & touch screen reponse & stopped the war & helped them with sex.... jokes apart i was tempted a lot of times and finally, two weeks ago i tried an alternative kernel (latest fluxi)

maybe it was me, or my configuration, but i found absolutely NO BENEFIT to change the kernel, i had several phone freeze and MAJOR RIL issues. in the end i tried to use the BLN feature and i realized why CM devs didn't put into the stock kernel (HUGE battery drain, doesn't worth it, IMHO).

after 3 days i came back to the stock kernel, and i realized that the touch screen is almost the same, IMHO stock is better. the battery life was very good as usual, the only thing i missed from fluxi was the auto brightness, that with fluxi works much better, but i don't really care about it, now i'm always in manual mode using the status bar to increse brightness when needed.

ABOUT THE RIL ISSUE:

after coming back to stock kernel i decided to look better into the RIL issue (with my very limited knowledge about the topic..).

-before july i had vodafone IT sim card and the same modem since may (XXLPW). only one day during a phone call the connection was suddenly lost and i had no signal for about 30 sec, then everything came back to normal. actually i can't be so sure that it was a RIL crash as it happened only once, and no more in almost 2 months of daily usage.

-around 10th of july i moved to another carrier (wind IT) then i started to have several RIL crashes. often it happened to completely lost the signal, and i had to reboot to get it back. also i had some call dropping. in the same period i tried also to change the kernel and, as i mentioned before, i got even more issues with RIL: no signal at all for hours, and phone becoming very hot, one reboot didn't solved the problem (sometimes two were needed).

-coming back to stock kernel i tried to flash the XXLPS modem because i noticed that it was the modem shipped with the I9100 official sammy rom for galaxys2 wind branded. still no good results :(

-finally (about one week ago), i decided to follow what Entropy512 said (previous modem has better behavior with RIL) so i decided to try several GB modem (KI3 and KI4) but i had very weak signal. searching with google i read into an italian android forum that the NEKF2 was good for some guys, so i decided to try it.

i'm using NEKF2 since then (about a week ago)and i had no RIL issue (and hopefully it will continue this way!).

i posted the long story instead of a short one because i was trying to find out why switching the mobile carrier had the result to increase the RIL issues. i realize that my actual operator (wind) has a weaker signal coverage than my previous one (vodafone) and maybe, the modem i'm using now uses consumes a little bit more power (this is what i've read in that forum, maybe is a myth, maybe not) to avoid the phone to stay in a signal then no signal then signal then no signal (and so on) state, stabilizing the network, and MAYBE avoiding RIL crashes. i guess that the more the network is stable, the less RIL crash shoul be experienced.

i hope my experiences could be useful to someone other than me :)

thanks to everyone who developed and contributed for the development of this great rom!

[ot]i'm also glad to see that everyone moved to the cm10 preview thread, there are no more tons of pages of "new nighlty has a great battery life!", or "the new nighlty if awful!! worste battery life ever" (with no changes at all!) [/ot]
