  • Restart the phone in Recovery (volume up button + Home button + power button)
  • After entering Recovery, select the following items:
    !!! If you have a PhilZ Touch custom recovery, then instead of all the points below, we use only one - Clean to Install a New ROM (i.e., then go to step 4) !!!

    - format system
    - format data
    - format cache
  • Next, choose choose zip from sdcard (if the firmware is in the phone’s memory) or choose zip from external sd card (if the firmware is on the memory card)
  • Select archive with firmware
  • Restart your phone, wait for the firmware to load.

Q: Do Samsung's proprietary technologies work on CyanogenMod? (Such as SmartStay, MultiWindow, etc.)
A: No, they do not work.

Q: When KitKat firmware appeared, did ERROR Status 7?
A: The old recovery does not support the installation of QC. Updated to the latest versions.

Q: I want to post logcat / report an error. What should I do?
A: Post in topics on the night assemblies AOSP KitKat. Since this is a nightly assembly, do not expect a quick fix. The rest of the discussion, for example, suggestions on what you would like to see in AOSP KitKat, leave in the official topics on the discussion of AOSP KitKat or in the topics on the discussion of night assemblies. Do not forget to follow the rules.

Q: Some applications crash with / do not start. What can be done?
О: Settings ->Applications ->Find the problem application ->Clear data ->Reboot. If this does not help, then perhaps the application is not compatible with the current version of the android. In this case, check if the application has been updated to fix problems, or contact the developer and report the problem.

Q: Why was there no night build today?
A: Either there were no new changes, or Jenkins (the assembly server) could not compile as a result of any problem. If the latter, then someone will manually check the problem and solve it. Please be patient and do not clutter up topics with similar questions.

Q: Is there a patch from Exynos root exploit and from Sudden Death ("Sudden Death") in AOSP KitKat?
A: Yes, there is. You should also use patched recovery to completely get rid of Sudden Death. Recovery can be found on xda.

Q: How to enable "Developer Mode"?
О: In Settings ->About phone, click 7 times on the "Build Number"

Q: What is Google Apps and what are they for?
A: Google Apps are Google applications and services (for example, Google Play). Initially, they are not added to the firmware (under the license of Google, developers are not allowed to do this). GApps need to be installed independently after each update.

Q: I can not find a market / add a Google account /
A: No Google Apps package installed. Download it from the links in the header and install via CWM.

Q: I installed AOSP KitKat some time ago. Now I saw that since then there have been several updates. Do I need to put all the updates in a row or is it enough to put the latest.
A: It is enough to put the latest.

Q: Why does the network icon change color after connecting to the Internet (from gray to blue)?
A: Blue is a connection to Google servers. You can disable the check only by turning off the background data transfer.

Q: Where can I turn on closing the application by holding the Back button?
О: Settings - For developers - Closing applications (check the box).

Q: Where can I see the numbers on the SIM card?
A: In the standard contact manager, they can only be imported.

Q: The regular player does not play AVI files.
A: There are no AVI codecs in the firmware - the Cyanogenmod team has no right to add them. they are proprietary. When developing CyanogenMod, only OpenSource is used. Use alternative video players.

Q: The program% name% does not work.
A: Check the compatibility of the program with KitKat (if you have ART mode, then compatibility with ART). Most likely, this is the problem of the application, not the firmware.

Q: The program% name% is not available in the Market. "Device not supported"
A: The program may not be adapted for Android 4.4. *. Perhaps the reason is the modified DPI, if you changed it.

Q: Why does the battery consume so much?
A: 1. The first 2-3 days after the firmware can quickly discharge the battery. To calibrate the battery must go through 2-3 cycles of full discharge and battery charge.
O: 2. After disconnecting from the BB, reboot and turn off debugging, if enabled.

Q: How to configure the restriction of the use of Internet traffic?
О: Settings - Data transfer - Set a limit (put a checkbox). In the diagram, set limits for warning (orange slider) and shutdown (red slider). To view the use of Wi-Fi in the Menu (press the touch Menu button), you need to turn on Wi-Fi traffic display.

Q: How to disable background data transfer?
О: Settings - Data transfer - Menu - limit the background. dir (tick box)

Q: How to disable broadcast messages?
A: Look here:Samsung GT-I9300 Galaxy S III - AOSP Firmware (JellyBean)

Q: How to set 3G / WCDMA only mode?
A: We dial in the dialer * # * # 4636 # * # *, select WCDMA only, go back, after about a minute the phone switches to WCDMA only mode.

Q: How to assign the completion of a call to the Power button?
О: Settings - Special features - tick the "Power button ends the call"

Q: What is the "nightly build"?
A: Automatically generated firmware builds with all the latest changes. Go out daily. May include errors.

Q: I recovered data using Titanium Backup, but my applications don't work?
О: Do not restore the system data, you will not see it. The AOSP KitKat has a different data structure.

Q: Does AOSP KitKat have music switching by holding the volume buttons?
A: Yes, there is.

Q: Why does my light bulb turn green by 90%?
A: Regular batteries are initially designed to charge up to 90% and not up to 90. Firstly, this prevents excessive battery wear, secondly, it helps to avoid overcharging (link1, link2).

Q: And why then on other firmware the light comes on at 100%?
A: The most plausible explanation is that in official firmware, the threshold for current drop in charging, switching the light bulb to green, is significantly lower than in AOSP KitKat. In fact, the battery still charges up to 90%, just AOSP is more honest about it.

Q: During the conversation, the interlocutor does not hear me and I also cannot hear him. What to do?
A: Readthis message.

Q: After flashing CM11 / OmniROM / AOSP / AOKP, KIES does not see the connected phone. What to do?
A: The fact is that the "Kies from Samsung" program works only with official firmware for phones that were officially released by Samsung. And all the mods coming out on the basis of or under the name CyanogenMod are an unofficial development. And in this case, the Kies program simply does not see the firmware data.

Q: What is the folder "0" and is it possible to remove it?
A: This is because Android 4.4 supports multi-user profiles. You are the first user and your personal folder on sdcard "0". Add another user and a folder "1" will be created for the new user.

Q: Tell me the device with this firmware is defined in Mac OS?
A: Yes, it is determined. Detailshere.

Q: How to make a screenshot of the screen?

Q: What is ART? How to turn it on?
We read here:Samsung GT-I9300 Galaxy S III - AOSP Firmware (OS 4.x) (Post # 26598688)
or here://savagemessiahzine.com/2013/11/09/123502

Q: MTP connection problems. What to do?
A: Who has problems with the MTP connection, try to go to Settings->Memory. Next, click the left button, the item "USB connection to the computer." and put a tick there. There should also be a tick in the settings for developers on the item "Debug USB".

The option of kernel settings and a description of the functions during installation:
* Consider I / O as CPU load - Yes
* CPU maximum frequency - 1.6
* MMC readahead buffer - 1024
* MMC I / O Scheduler - CFQ
* Low Memory Killer Presets - Light
* Hardswap - Yes (or space setting, I don’t remember. It’s on exactly, in general)
* zram - 250
* Fast charge - did not change
* Sound output level - both +1
* Dynamic fsync settings - On
* init.d script support - off

If briefly explain -
* Load the processor while the disk is loaded
* Maximum processor frequency
* Preloading buffer (allocating space to the application before its request for allocation. I do not advise you to set great value, because the application may not require it to allocate space)
* CFQ - preset on disk write performance. There are still Noop and Deadline in this core - both to save charge
* Setting the closure of applications when there is a shortage of RAM. I put almost the most gentle, because with my applications it is simply not necessary =)
* In fact, the expansion of RAM, allocated a section on the disk that acts as a buffer, there are cached processes. It may slow down the download of some applications, but I'm not in a hurry =)
* Compressed section of RAM, to save it
* Fast charging (change of voltage). I do not advise to play with it, because you can burn the power controller, if you do not know. I have a charge for Nokia with a current of 1.2A, but I still do not increase it, for nefig.
* Sound booster
* Long to explain what it is. In short - recording performance gains without any damage to the battery.
* Too long to explain, but I do not advise you to change it if you do not know what it is.

Hello. What to do if you do not work on the nfc data transmission (android beam) on Cyanogenmod 11? All-inclusive, the second phone Nokia 3.1 is not transmitted. In general, the proposal does not appear to convey. I know that in the non-original batteries, there is no antenna NFC. But. I completely original Accum. Bought 2 years ago for 1500. All NSF checks show that the NFB is working. But in the context menu in the gallery, Youtube does not appear to convey a proposal for android beam. Also there is the original battery that is planted in an hour, just in case I checked (it has an antenna 1000%). And there is the same picture! GT-I9300 Cyanogenmod 11 last snapshot.
