Instructions

To flash an the ROM, you can either:

Download a zip archive from above and flash it from recovery by sideloading the zip (using adb sideload) or by

just copying it to the device (using adb push or MTP file transfer) and installing it. Instructions are below under

Zip Instructions.

Download a tar.md5.xz archive which can be flashed via ODIN. Instructions are below at ODIN Instructions.

After CM-12.1 is installed, flash either the GApps package linked above, or download openGApps, but only

the micro version, otherwise there will be app conflicts between the CM apps and the GApps.

After flashing an image successfully, simply check for updates from System->About to update thereafter.

Device Names

Verify your device codename before downloading any firmwares or recovery images!

Note

Do NOT ask for help/post issues if you:

[LIST]
[*] Have flashed mods (Xposed, etc);

[*] Didn't read the OP;

[*] Didn't follow intructions to the word.

[/LIST]

And most of all, I'm not taking feature or device requests.

Disclaimer

I'm not willing to help anyone who damages their device because they didn't take the time to read any instructions I may have written

up, and I'm not willing to do any hand-holding when it comes to flashing custom firmwares. I assume beforehand that you know what terms

such as "Odin" and "recovery" mean in this context and the basics of flashing firmwares using Odin and custom recoveries.

These packages are distributed in the hope that they will be useful,

but WITHOUT ANY WARRANTY; without even the implied warranty of

MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

I'm not responsible for any bricked devices, etc, etc, as a result of flashing these images. It is assumed that by downloading one of

these images you possess the prerequisite knowledge required to flash such firmware image.

Zip Instructions

[*] Download and install a TWRP recovery file for your device if you are on stock recovery. You will have to flash the recovery

.tar file for your device using ODIN (see ODIN Install below) or by using one of several applications from the Play Store such as

Rashr (will require a rooted phone).

[*] Download a recent .zip file from the links above for your device.

[*] Reboot into recovery mode [Press Power+Volume Up+Home].

[*] Wipe your data and cache partition (equivalent to doing a Factory Reset) if you are coming from a stock ROM.

[*] Either: Plug in your phone into your computer, copy the zip file to a location on your Internal or External Storage on a

device, click Install on TWRP on your phone and locate the zip file in the phone, or:

[*] Plug in your phone into your computer, and open Advanced->ADB Sideload on TWRP on your phone and swipe the slider to enter

sideload mode. Then open a command prompt/terminal on your computer in the folder you put the file by Shift-Clicking (Shift+Right

Click) and selecting "Open Command Prompt/Terminal Here" (you will need to have adb installed) and type:

adb sideload name_of_zip.zip

to sideload the file. Replace name_of_zip.zip with the name of the file. If you are running Linux you may need to type

adb kill-server and use sudo adb sideload if you get an `Insufficient Permissions` error.

[*] Download and flash GApps in the same way (optional).

ODIN Instructions

The flashable images are hosted at the link above.

The directory contains tar.md5.xz archives. The tar.md5.xz archives are named according to the date the image was built, e.g

cm_gprimeltecan-ddmmyyyy.tar.md5.xz and can be uncompressed to yield the flashable .tar.md5 archive.

Each ODIN flashable .tar.md5 contains the boot image, recovery image, and system image for flashing.

Installation

[*] Enable Developer Mode on your phone and unlock the bootloader from the settings, if not done already.

[*] Download a recent compressed flashable image above.

[*] Reboot into Download Mode [Press Power+Volume Down+Home].

[*] Extract the tar.md5.xz archive with 7zip or `xz -d cm_gprimeltecan-ddmmyyyy.tar.md5.xz` if under Linux or Cygwin to get a flashable

tar.md5 file.

[*] Flash the tar.md5 archive using ODIN by clicking AP and selecting the .tar.md5 file you just

extracted. If the file was corrupted during download, the installation will fail. You will need to redownload the file in this

case.

[*] You will need to wipe your data and cache partitions afterwards (equivalent to a Factory Reset) if you are coming from a

stock ROM, which can be done by rebooting into recovery [Power+Volume Up+Home].

[*]

Download and flash GApps (optional).

Changelog

01/11/2016

* [ fixed ] NFC is now working.

* [ note ] This batch will be the last build(s) for CM-12.1.

30/10/2016

* [ G530FZ ] Changed kernel source

* [ G530FZ ] Rear and front camera should be working as [MENTION=4981011]kentone[/MENTION] said.

12/09/2016

* [ G530FZ ] Enabled LTE

* [ G530FZ ] InputDisabler should now be working fine.

* [ G530FZ ] Fixed up camera code in kernel. If rear camera still does not work, then this is an issue in

the proprietary files.

08/09/2016

* Added a few more frequencies to the cpufreq kernel table (overclock to 1209MHz, and addition of 1152MHz).

Please don't request for me to add anything higher; the CPU is rated maximum for 1209MHz (even with nitrogen cooling, and so on), so it is

impossible to go past this.

* Added the "Particle" charging animation from the stock ROM. Off-mode charging should be working proper as well.

* Fixed Viper4Android (module was not named properly when copied to system).

* Updated InputDisabler code (the software that turns your touch screen off when you call).

* Tuned Kernel Samepage Merging to be less agressive with memory page merging. This should fix the responsiveness issues that popped up

in the last builds.

* ZRAM is available for all devices (fixed at 512MB), but only enabled by default for the G530FZ. There's a post somewhere on how to

enable it in the thread.

* Patched the update zips from today's builds with an old updater binary (zip updates should work again). I removed the zips from

Jenkins so they're only available from the /builds/ directory on the root of the web server.

* Added a few more screenshots.

* Any other changes in the log are more concerned with refactoring of code in the device trees, etc.

05/09/2016

* Added new build server [Bilbo]

* Added Viper4Android as the default equaliser.

* In-call audio now working.

* TWRP is now the default recovery [in the ODIN images]

* [ G530FZ ] Fixed zram properties, added other low-memory tweaks

* Enabled dex pre-optimisation [= Faster app startup, lower memory usage, quicker boots]

* I dunno what else, you check and see.

01/09/2016

* [ G530W ] The sleep of death issue should be gone on the latest successful build, and the device should be

going into deep sleep properly. I have yet to resolve this for the other devices (probably in a few days).

31/08/2016

* Fixed InputDisabler

* Added qcom powerHAL (might hopefully fix sleep issue)

+ Various other fixes ( file access permissions, kernel tweaks)

29/08/2016

* Initial work on cpu undervolting.

28/08/2016

* Fixed MTP support in TWRP (if you use TWRP, reinstall it).

* TWRP now shows proper disk free space information.

* adb sideload now works in TWRP (may need to kill adb server and start as root to do so).

* Added new device (SM-G530T1).

* Added VoLTE support to SM-G530FZ (Still no in-call audio :( ).

* Added darkness cpufreq driver (from Mokee kernel) to kernel.

* Enabled ZRAM by default in SM-G530FZ.

* Trebuchet and System UI should be working properly now (ostensibly it requires hardware rendering,

which is disabled on low-ram devices by default).

+ There may be other minor fixes I missed here.

25/08/2016

* MTP is now working (properly)

25/08/2016

* MTP is kinda working (I'm investigating)

* Modem is now fully working on G530FZ (calling, audio, data).

* All sensors (gyro, magnetic, proximity) working on G530FZ.

19/08/2016

* Fixed WiFi tethering

* Fixed issue with WiFi and bluetooth MAC addresses (were not set properly at boot).

* Added Samsung Doze app

+ Several other minor fixes and tweaks

14/08/2016

* Kernel is now built entirely from source

* WiFi should be working again on all builds

12/08/2016

* TWRP recovery is now available (I will not bother servicing any issues regarding this if it doesn't work for you, it is included here

purely for the purpose of providing a different recovery to those that want one.)

* There do not seem to be any more sleep-of-death issues (this seems to have ended the last build).

* Over-The-Air updates are now possible, simply check for updates from System->About (after flashing this image).

03/08/2016

* Recents button is now working (thanks [MENTION=6940293]Has.007[/MENTION] !).

* I'm not going to be uploading any new images because I'm currently working on getting the kernel to build from

source, and (I'm occupied with exams and schoolwork in general), so no new images are going to be pushed until this works properly (I had

to cobble this one together from a failed build on the custom kernel).

31/07/2016

* Added a few tweaks concerning CPU frequency scaling so there should be power savings from that as well as lowered device temperatures.

* Kernel Adiutor frequency scaling now works properly.

30/07/2016

* The previous update was buggy and kept crashing, I pulled that one and uploaded a new one which should hopefully fix that.

29/07/2016

* Minor tweaks

25/07/2016

* Both front and rear camera work as expected now.

* Trebuchet now displays the lock screen image properly.

* Trebuchet now displays full windows in the Recent Apps switcher.

* GPS is working

24/07/2016

* WIP - I had uploaded an image but I pulled it because filesystem mounting was broken in this build.

* I have pushed a new image, but something broke in the build which is preventing the sdcard from being mounted at boot by Vold (an

explicit entry had to be put in the fstab). I will be reverting changes and looking for a fix so there might be no build for the next few

days.

* Mobile data is now working in this build, but phone calls can still neither be placed nor received.

* System detects SIM card properly.

* GPS is not working.

* Rear camera works properly with the default camera app, however the front camera does not work with the default application and trying

to switch to it will cause the app to crash and refuse to open.

* Recents button is still not working (I had thought I fixed it but apparently it isn't working).

23/07/2016

* Limited mobile connectivity [ sending/receiving texts ].

- Calls can be received or made but there is no audio (speaker or microphone).

- Mobile data is not working.

- Currently the system does not show the mobile connection as active, but texts can still be sent and received.

* Screen brightness controls working

22/07/2016

* Limited mobile connectivity [ sending/receiving texts ].

Currently the system does not show the mobile connection as

active, but texts can still be sent and received.

* Fixed troublesome cgroups problem, meaning:

Apps can now be installed on the device; and

Apps no longer crash.

* Minimal camera capability - camera image is distorted, and only back camera works.

21/07/2016

* Wifi connectivity now available. [module has to be manually loaded - use adb shell su modprobe wlan ]

* Bluetooth is now working.

* GPS is working.

* Audio is working (microphone, speaker)

* Multimedia playback working

* Sensors are working (magnetic, rotation/gyro,proximity)

21/07/2016

* Initial image created.
