[Galaxy S II General] Coirpre:
To the Moderators:

This is a try at lowering the rate of repeated questions in the CyanogenMod 10.1 official nightlies // discussion thread. I am aware that this thread would probably belong in the "Q&A" section, but I fear that it will get buried and forgotten there. I beg you to consider the idea of this thread and leave it in the "General" section.

Have you flashed a CyanogenMod 10.1 official nightly? Do you have questions and problems? This post is here to help you!

Please read the entirety of this post before asking questions in the CyanogenMod 10.1 official nightlies // discussion thread!

It is assumed that you have read the first post of the CM10.1 thread (called "the OP" in the following).

If you were not able to find your information by yourself, or would not have been able to without this thread, you should reconsider flashing a CM10.1 NIGHTLY.

I will not answer Questions in this thread.

I get a "status 7" message when flashing with CWM!

It seems you are running PhilZ Kernel or a derivative of it. This kernel seems to be broken and unable to flash. Flash Siyah, Dorimanx or any other Kernel via CWM or ODIN, boot to Recovery and try again.

My phone asks for a PIN or some other code which I don't have!

You have a SIM.Locked Phone which was unlocked via an exploit. Samsungs kernel-update fixes a few issues, including those exploits. Use GalaxSim Unlock to re-unlock your phone.

Youtube/Market/GMail crashes!

You need to flash the corresponding 4.2.1 GApps, currently 20121212.

The Clock app (or any other app) crashes!

Go to Settings -> Apps -> All -> Clock (or whatever it was) and delete it's data.

Are there any other kernels supporting CM10.1?

As far as I know, all Siyah-based Kernels should work. Remember that you are not supposed to post on the CyanogenMod 10.1 official nightlies // discussion thread when using a different kernel.

I have flashed [insert any kernel here], now my phone won't boot!

The kernel obviously does not support CM10.1/Android 4.2.1. Reflash the ROM to get the stock kernel back.

Where are the developer and performance options?

Google has hidden them. With good reason. You can render your phone unbootable if you use those incorrectly. To quote Codeworkx: "bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed."

If you apsolutely need to use them, tap Build Number until you are a developer (about 7 times).

I unlocked the Developer Options and tried to use "Simulate Screens". Now my screen is black and won't turn on again!

That is why one does not simply mess around with the dev options. Reboot your phone and press vol. down while it's booting. This will boot it to Secure Mode, where you can go and untick "Simulate Screens". Fixed.

I cannot find Photosphere! Will it be added?

No. Photosphere is not open source and therefore only available for Nexus devices.

Charging speed is very slow!

Due to hardware limitations, there are only three possible charging speeds, one of which is never used. The others are 450mA on USB and 650mA on the charger. Your phone is either draining power while being charged (media scanner?) or has a problem with the USB connector. Try cleaning it CAREFULLY or find the app responsable for the drain with BetterBetteryStats.

I want to disable the Lockscreen Widgets

Use Lockscreen Policy from the Play Store

The weather Icon of Chronus does not show on the lockscreen!

You can maximize widgets in the Lockscreen Settings. All your Lockscreen widgets will be maximized after turining the screen on. If you want to know why there's no better Option read this.

Sometimes I get freezes when scrolling through long lists!

I have never experienced this. People suggest that ticking "Force GPU Rendering" in Developer Options solves this. Other People suggest that forcing GPU rendering breaks other things, e.g. the keyboarld leaves a black space in WhatsApp. I have never experienced this, neither.

My Car Stereo/Handsfree/other Bluetooth device does not work correvtly!

All AOSP 4.2.1 ROMs including the Nexus 4 seem to have problems with Bluetooth, or more specifically A2DP. Rumour has it that it will be fixed in 4.2.2.

I get "Out of storage" messages and can no longer install Apps!

Viber and Lucky pacher are known to trigger this. Try to move them to your external SD card. If that doesn't do the trick, search /data/apps for .odex files and delete them.

I get tons of dumpstate_ril_RESET_BY_CP_SILENTRESET.log files at /data/log !

These are logs of RIL crashes. Do NOT use GetRIL to fix this. Use this instead. These zips flash modem, RIL and a few other related files. They are much more reliable than GetRIL. You can also try to Flash XXLS8 without RIL and hen reflash CM, it comes with XXLS8 RIL.

The rotation- and the acceleration sensor do not work anymore!

Deactivating tilt to scroll in Chrome should help.

Real Racing 3/Simpsons/other games crash after a very short time!

Blamesung. This is a problem with the current mali driver (mali is the graphics chip). Do not expect it to be fixed. There is a possibility to flash older drivers and fix the gaming issues (see siyah kernel), but that will bring the graphical glitches in the UI and keyboard back.

UPDATE: It seems to me that it's not the mali driver, but the audio HAL acting up. I have sudden loss of audio and a game crash a few seconds after, most prominently in World of Goo, and some people report that disabling all things audio via in-game controls fixes the crashing.

I still have a problem that was not discussed here!

Reflash the ROM and wipe cache and dalvik cache in Recovery. Reboot. Delete the data of the app that is misbehaving. Search the CyanogenMod 10.1 official nightlies // discussion thread to see if anyone has had this problem before you, and if there is a fix. If all of this fails, ask in that thread and someone will hopefully try to help you.

IMPORTANT INFORMATION

I have moved on to a Sony Xperia Z. I will not trouble myself with keeping myself, the OP or the thread up to date. If you have very common problems and a solution, PM me and I'll update the OP. If you want to take over the management of this thread, PM me and we'll find a solution.

Happy flashing and bye!
