After these steps:

power off phone

eject sd card from phone and connect to pc and delete its "Android" folder and reinsert it into the phone

boot into recovery

wipe data/factory reset

wipe cache partition

advanced --> wipe dalvik cache

format /system

format /preload (this stepa actually gave an error... I don't know what it does exactly)

install from zip the 30/04 rom

install from zip deltadroid gapps (gapps-510-base-20150422-2-signed.zip)

restart phone

configure wifi and installed many applications without problem

reboot phone

charge all the night

power on at morning

all seems come back ok again

I've got 2 freezes until now: screen blocked in the app where it was and no way to unlock it

(tried back button, home button, volume buttons and wait about 1 minute too)

only way keep pressed power button and have the phone reboot

The first time I don't remember where I was; the second one I was in gmail

I see that logcat contains info since reboot... Is it possible to find also information before so I can send?

Apart these two little problems, the phoen seems fluid and ok as with the 13/04 I have used for about 15 days without any freeze at all

(I power off the phone each night; I don't know if this can make any difference with others that keeps it always on)

Thanks again,

Gianluca

Problem making nandroid backups

Hi, since clean installing build 04/23 I can no longer make backups to external sdcard. When I boot to recovery and select 'backup to storage/sdcard1/' the backups completes /data, /system, etc, and then fails with the error:

error while making a backup image of /sdcard0/.android_secure

I have tried manually mounting/unmounting /storage/sdcard and /storage/sdcard1 before the backup, and they definitely have enough space for the backup on them?

Does anyone know what is causing this or how to fix it? Backups to /storage/sdcard still seem to work fine but now I don't want to trust them in case they are failing too without throwing up the error. What is .android_secure and why does it prevent backups to /storage/sdcard1?

build 30/04 unable to see internal sd card 13/04 was ok

Hello,

it seems that for me all is good on 30/04, but the internal sd card access.

when I open camera app it says it needs an sd card inserted to use it.

when trying to see whatsapp photos it says it is unable to download

in es file explorer I see these related folders under / :

extSdCard (link to external sd and ok, see sdcard1 below), storage, usbdisk0 (empty)

Under "storage" folder I see

sdcard1 (that contains external card root contents)

usbdisk0 (empty)

sdcard0 (marked with a question mark icon)

Under / I don't see any "/sdcard" directory and for example when I open es file explorer, in the bottom part of the screen I see a floating message saying that it cannot find "/sdcard" and indeed it is not here...

How can I further check? Would a logcat give any insight of the reason of this problem?

I used for about 15 days the 13/04 release and access to internal sd card was ok

Thanks in advance,

Gianluca

CM12.1 updating on S2

Hello There

I have loaded cm-12.1-20150423-UNOFFICIAL-i9100.zip

So far I have got only these two issues:

- sometimes my browser gets crashed.

- Direct dial contact on lock screen --> always looking to use Skype to make calls, once I restart the mobile then it is ok.

Now I want to flash cm-12.1-20150430-UNOFFICIAL-i9100.zip.

Do I need to wipe off everything and start again or I can just flash on top of previous rom. ( I thought it just saves time me not have to reload all other apps)

Hi guys! I have cm11 on my galaxy s2 and i want to flash cm12.

My kernel version is: 3.0.64-CM-g89e6992build04@cyanogenmod aug 2014 and the recovery version is 6.0.5.0

1) Do i need to upgrade the kernel or the recovery(from 6.0.5.0 to 6.0.5.1)? I never changed them, they are from the last official update from cm10 to cm11(settings>about phone> update)

2) I know that before flashing the rom i have to: wipe data, wipe cash, wipe dalvik cash. I saw on youtube someone goin to mounts and storage>format sistem. Do i have to do this too?

3) If i have to update the kernel, when using odin, do i tick the reboot box or untick and after it's done i remove battery and start in recovery?

I've never used odin or flashed a rom, just used cm installer so i'm total begginer

Hope you can help me! :D

Try a clean flash? For most users (including me) front cam is working fine. Which Camera App? Stock CM?

This ROM is only for GT-I9100, that's the regular S2, unfortunately not for S2 HD LTE.

Gotta wait for this to be implemented ;) this is clean CM, so we have to wait for CM Team, I assume.

Except for indivdual bugs discussed in this and main thread, there are no major bugs. Runs smooth, stable and responsive :D

1) Nope, you can stay with 6.0.5.0, it's KK compatible and will automatically be upgraded. ;)

2) Yes, before flashing it's best to wipe system, data and cache (as you mentioned, in the mounts menu in recovery) as well as dalvik. This will avoid unnecessary problems ;)

3) If you are using CM11 (as you wrote it), you can simply follow these steps:

- Optional: Backup (Titanium Backup oder Nandroid over recovery for example)

- boot into recovery

- wipe system, data, cache and dalvik

- flash this ROM (zip file)

- flash GApps

- I always clean cache and dalvik once again after installing LP and GApps, but don't know if that's necessary ;)

All Downloads are available in first post in main thread or in linked threads

Good Luck! Hope this helped you!! :D

Have you installed BetterBatteryStats? Maybe take a look at wakelocks what drains your battery, because my phone is fully charged within 2-3 hours (from ~10% to 100%, with slight usage during charge). And else try reboots.

Wifi on but not connected

Hello Lysergic,

I came from a 4.4.2 rom and made a clean install of your 4/30 version. when I first set up a wifi connection it works well. however if I have mobile data ON while Wifi is OFF and I switch it ON then the wifi icon will show an exclamation mark and will not obtain an IP address. the connection remains on mobile data. there are only 2 things that can switch to wifi:

1. forget the access point and then configure it again and connect.

2. turn mobile data OFF (it's possible to turn it back ON and it will keep the wifi connection).

But it should just smoothly transition to the wifi connection when I switch wifi ON.

Any suggestions?

Thanks.

[Galaxy S II Q&A, Help & Troubleshooting] Dark1Angel:
I have 3 questions:

1) i downloaded the necesarry files to copy on phone and install cm12.1 and they are zip. Do i need to unzip them of copy as they are?

2) on youtube i saw them copying the files on sdcard0(interal memory) . A friend of mine told me(and it seems logic) that if i copy them on internal they will be deleted when i wipe data or when i install the rom so i won't be able to installl gapps and to copy them on external card. So which one is true?

3)which version of cm12.1 is the most stable and without issues in: google play, signal etc?(of course the latest, the better but i prioritise stability over inovation)

I understand thet for camera i can use other apps that work perfectly.

[MENTION=6159291]Lysergic Acid[/MENTION] when will you upload the next update
[Galaxy S II Q&A, Help & Troubleshooting] martidroid:
1) No need to unzip, as the option in recovery is called "flash zip file" ;) download and flash :D

2) "wipe data" is not equal to "format internal sd", these are two different options. By wiping data you clean all your "user content" (apps and app data), but by wiping internal sd, you delete all your downloads, music and all the stuff on your internal sd. There's no difference between flashing from internal or external, as long as you don't format internal sd ;)

3) Well, that's a good question. There are lots of people having lots of different bugs on different builds, while I have not experienced any of them. So just try and flash ;) if it's not stable or there are bugs you can't live with, try an older build ;)

---------- Post added at 06:31 PM ---------- Previous post was at 06:28 PM ----------

Try a reboot and wait few minutes. If this doesn't help, install BetterBatteryStats or go into Settings > Battery (don't know how this menu is called in English) and take a look at what is taking much capacity. But I think a reboot will help. ;)
