[Galaxy S II Q&A, Help & Troubleshooting] martidroid:
As mentioned in the main thread (next to download link), there are RIL issues in latest build, so I recommend using build 05/08. Bugs are often user dependant, so just try and see for yourself :D

You don't have to unlock bootloader. Maybe the YT video was a tutorial for a locked phone, but the SII has no locked bootloader. Simply install recovery and flash. ;)

And concerning battery life: This depends on the apps you use and are running in background. I have a loss of 5% at night (6-8h) and get at least 1 day (depends on usage, screen-on-time etc).

Hi, i've installed 05/14 yesterday (coming from 05/08) like this: Wipe Cache + flash rom + reboot. When i clic in "reboot now" on Recovery, he tell me that reboot root are damaged or something like this, i clic on "repair now" and then, when i reboot and trying to put my PIN SIM card, the device loading ~ 1 minute (before it's just question of seconds) and then tell me "Failed to unlock system using the PIN code of the SIM card." some thing like this. I remove SIM card and reboot but there are an other problem, each second google play and google gapps crash.

[Galaxy S II Q&A, Help & Troubleshooting] martidroid:
To me it's always helpful to analyze my energy consumers using the app BetterBateryStats (if you don't this app yet - you can get it here on xda).

But it can also result from a dirty flash (no wiped caches etc). Sometimes even a simple reboot helps out.

Don't repair root - this message comes every time you leave cwm.

And as mentioned next to the download link, there are RIL issues (that means issues concerning network and connectivity). So it's safest to stay with build 05/08. ;)

As solution, try to format system (in cwm) and reflash 05/08 build and GApps. Your data won't get lost ;) if issues remain, try a clean installation.

---------- Post added at 03:08 PM ---------- Previous post was at 03:01 PM ----------

As for many users wifi works fine, it might be a hardware problem for you. Someone else had this problem here.

Did you make a clean install?

To me and many users, battery lifetime is very good. I made now 1.5 days with 3h screen-on-time. No battery issues to me.

Sytem freeze, stuttering

Hey guys,

I am using the CM-12.1 on my i9100 quite a long time, but since the last about 3-4 builds I encounter system freezes quite a lot. It always occures especially when I am seeking in music, no matter what player I use. The only way to get the system back to work is removing battery and rebooting.. very annoying. In addition when I have rebooted I notice a huge battery leak. It also occured sometimes in the past when loading the keyboard.

Is it a already known problem and are there any workarounds?
[Galaxy S II Q&A, Help & Troubleshooting] good8life:

[Galaxy S II Q&A, Help & Troubleshooting] martidroid:
Yes, the battery leak after rebooting is a known CM bug. Was also present in CM11.

Exchange services crashing

I can't run exchange services with this latest version. I have re flashed a couple of times and even tried to us PA gapps but exchange keeps on crashing. I have cleared out the chache and data files I even did a couple of complete re-partitions and started over with stock roms.

As soon as the phone tries to sync with an exchange server the program crashes.
[Galaxy S II Q&A, Help & Troubleshooting] martidroid:
Which build / ROM do you come from? As mentioned, it is not recommended to "normal users" to flash latest build (05/14). Rather use 05/08 and wait for next build, if there occurred no errors.

wifi not working

first of all thank u for ur hard work on the rom but i got one issue the wifi just worked at the first boot time but then if i reboot the devices wifi will not worked till i do a factery data reset i tried to updated from beta 8 to to 5/8 but still the same thing help me plzzzz :(
[Galaxy S II Q&A, Help & Troubleshooting] martidroid:
Did you make a clean flash? Backup your important stuff and then: format system, cache, data and wipe dalvik cache, then flash this ROM (05/08 is best, if you neither want to have issues with RIL nor using terminal commands) and GApps.

If wifi works - alright.

If wifi stops working after restoring your backup - you know where the problem is ;)

Hope this helped you a bit :D

Flashing this ROM overwrites your custom kernel, but reflashing (if kernel is lollipop compatible) will replace CM kernel with your custom one.

Good luck ;)
[Galaxy S II Q&A, Help & Troubleshooting] MartinX3:
I came from the last CM11 nightly to the 14/05 Nightly of this unofficial CM12.1. (Yes, i need to use the FIX on a clean wipe to get the SIM working)

It works much better, no more lags or slow behavior.

It needs less space on my Galaxy S2 with same GAPPS and all of my APPs recovered with titanium backup.

Thank you, that you let the newest CM work on this wonderful piece of hardware :)

But i have the problem, that it gets hot, if i do something, like using the data explorer or the browser.

The second problem are the I/O-Errors if i want to transfer files from my PC to my external SD-Cart.

If I use the CWM recovery, i can transfer the files without this problems.

And i have two questions:

Can i use the build in Updater, to update this ROM?

And, why it is unofficial and not downloadable via http://download.cyanogenmod.org/?device=i9100 ?
[Galaxy S II Q&A, Help & Troubleshooting] martidroid:
My phone also gets hot sometimes, normally after flashing clean rom. Maybe because of the heavy working CPU.

Did you analyze your energy consumption? (--> BetterBatteryStats)

Also take a look at your CPU gov (you can never know...) and CPU States

I just tried and did not get any errors. Transfer with good speed (not using cwm). Maybe it's the latest build? (I'm on 05/08)

Which kind of errors? (I assume you are using windows)

No you can't update in CM Updater as there is no update server for these builds.

CM Team did not want to develop and support CM12 for our S2 ... That's why this is unofficial, but afaik this might become official :D:good:

(guys, correct me if I'm wrong :P )
[Galaxy S II Q&A, Help & Troubleshooting] MartinX3:
I'm using the CPU Governor PegasusQ, because it can disable cores, if not needed. Saves energy :)

And the IO Governor ROW, because i read more times, than i write data. :)

I used BetterBatteryStats in CM11, i will reinstall this app :)

I'm using Linux Mint 17.1 and the last build :P

And they don't occur in CWM :)

Oh :(

But couldn't the maintainer of this build become the official S2 CM Developer?

Another problem is, that sometimes, cm12.1 wont REmount my internal and external sd card, even if i disabled MASS Storage. (After i connected it at my PC).

And it is getting VERY hot while booting. :(

If my phone rings because of my APP AlarmDroid, it gets very hot and my Battery is empty, after 30 minutes.

And i feel no much different in the behaviour or the battery life, if i use the new energy save mode.

Ok, here's the full story: I am coming from a previous cm 12.1 build from Lysergic Acid. So trough ODIN I flashed a PIT file and a CWM-Kitkat-combatible-i9100.tar, witch formatted my internal memory (I flashed the 8GB 45mb preload [NOT FOR STOCK ROMS] by metalgearhathaway http://xdaforums.com/galaxy-s2/development-derivatives/mod-partition-internal-memory-app-t2538947/) after that got into the recovery pushed cm10.1.zip(I had to push it to my external sd card because CWM couldn't mount /storage/sdcard0/) through adb and clean flashed it(deleting data,cache,dalvik cache and system),after boot it gave me a pop-up saying that I have to reformat my internal SD card so I did (that created Android files on the internal SD card and cwm could now mount /storage/sdcard0/). Then I went back to recovery and clean flashed cm11(SNAPSHOT) to see if that works and it does. I didn't mess around in cm11 and clean flashed cm12.1 and got stuck on boot animation.(3 times went to cm11 and back to cm12 because it was stuck on boot animation,but that did nothing) please help!

I don't know where you get your information from. All governors on the s2 has hotplugging support (feature to disable unneeded cores) for our device, hotplugging is done by the hotplugging governor (not available to be selected on built-in kernel). So that means the default should give same battery savings too (or any other governor other than performance).

---------- Post added at 06:35 PM ---------- Previous post was at 06:31 PM ----------

That's not true. CM updater is only for official builds only. When there's official, there will be cm updater nightlies and etc.

Again, CM Team is not responsible for giving support most devices. It's usually because of the maintainer has left or have moved onto a new device. We had no maintainer for a while now, and plus there were a lot of issues on the progress of making cm12 stable for our device.

Sorry for picking on you, I felt that you were a little misinformed on some information.

---------- Post added at 06:38 PM ---------- Previous post was at 06:35 PM ----------

Flash a different pit file, possibly one without modified preload to remove future errors from popping up.

With which CPU- and I/O-Governor will i get the most energy saving and stable behaviour?

(Except the powersave governor, it will only use the smallest cpu frequenzy, which would make my phone unresponsible) :)

Could it be possible, that the maintainer of this unofficial build become the official maintainer of the CM-Builds for the Galaxy S2?

---------- Post added at 05:45 PM ---------- Previous post was at 05:29 PM ----------

Try the way, i did it :)

Use HEIMDALL or ODIN to flash the zImage in this zip.

It is the Apolo 8.0 Beta 9 kernel.

AND this pit file ("I91001GB_3GB.pit") together.

Don't forget to tick the "repartition" checkbox. :)

Now boot into the TWRP recovery and make a full wipe.

And format the internal and external SDCard to VFAT.

Now flash the latest CM12.1 build and the gapps of your choice.

I prefer this gapps, because they are small and i don't need the extra apps.

Don't forget to untick the "inject TWRP"-Checkbox after you choose the zip and before you touch the flash button!

TWRP gave me bootloops/problems.

[Galaxy S II Q&A, Help & Troubleshooting] DasOlliginal:
First thanks a lot for the ROM, running very smooth so far :)

I have one problem though and I'm not sure if it's just my phone that fell down a hundred times already or a ROM problem. My compass is stuck somewhere around north (Only moving a few degrees and it seems rather random). Already tried the usual calibration movements and so on but didn't see any improvement. Is the compass working fine for others with this ROM or is it a general problem up to now?

Great that CM 12 is still provided for that old phone, it just doesn't want to die even though I don't treat it very nice so I guess I'll have to keep it for quite some more time ;)
[Galaxy S II Q&A, Help & Troubleshooting] KikoFMC:
It had to be at least 15-20 minutes.
[Galaxy S II Q&A, Help & Troubleshooting] MartinX3:

I had to wait 3-5 Minutes :)

By the way, if i hear music with headphones and change the volume, the slider doesn't refresh its position.
[Galaxy S II Q&A, Help & Troubleshooting] taspac:
Same issue with Compass for me too, also it is stuck showing north. At least it is a relief that it is not HW fault, as I was already thinking :)

Also GPS works poorly, detects your position, but acurate actual navigation is impossible. Cannot keep lock, with "GPS test" sees only 3-6 sattelites and locks to them only if I am standing still in one place (but locking time is ~10 sec which is very good) + that lock does not keep for very long, keeps locking, unlocking, locking again constantly. Accurasy in only ~40 meters, when locked.

Waiting for new releases and hoping these issues fixed. Rest is working so smooth that I have even dropped idea of buying new phone. Especially after official CM11 which was crap compared to this version.

No, as this is a different OS, you have to do a clean flash.

And if you use a small GApps package, there should be no problems with system partition size.

I think this is theme dependant, normally there is the same wallpaper, but there are themes that allow two different ones - but I don't think that it's changeable then. This is at least what I experienced. (example: With TouchWiz Theme from Playstore, I can apply lockscreen wallpaper, but cannot change it.)

It's on path to become official, but it's hard to give estimates, because it depends on how fast LA (the developer) can address remaining issues and also how much time it'll take the Cyanogenmod guys to review and merge LA commits.
