[Galaxy S5 Mini Android Development] hennymcc:
CyanogenMod is discontinued.

This ROM is continued as a LineageOS ROM.

Check the G800F LineageOS ROM for more info.

This is a CyanogenMod 14.1 ROM for the Exynos3470 based Samsung Galaxy S5 mini (G800F/G800M/G800Y).

DO NOT USE IT FOR G800H OR YOU WILL BRICK YOUR DEVICE

Although G800F and G800H share the same name they are not related in terms of hardware due to the different SoCs used (Exynos vs. Snapdragon).

Hence please do not ask for support or ROMs for the G800H.

Important note: It is possible that flashing this ROM can cause efs partition issues. Therefore it is strongly recommended to make a backup of your efs partition before flashing this ROM. This can be done via TWRP.

Before you start:

Backup your data, like call history, contacts, sms, WhatsApp messages, favourite app settings that are on internal and external sd (by using Titanium Backup or other apps available on PlayStore). At least all internal data will be lost in any case. If you have bad luck you might also loose data from your external sd card.

Download:

Odin3-v3.07 (it is contained in CF-Auto-Root)

TWRP 3.0.0 recovery image [25/03/2016] (AndroidFileHost Mirror)

CM 14.1 ROM for G800F/M/Y (Android File Host)

Google Apps (contains Google Play, ...) for Android 7.1. The following is recommended:

Open GApps Project, Platform:ARM, Android:7.1, Variant: whatever you prefer (e.g. "mini" or "nano")

Install recovery:

Reboot your device into Odin mode: turn off your device, then press Volume-Down + Home + Power button at the same time and release them.

Confirm the following warning message with the Volume-Up button.

Connect your device to your PC via USB

Make sure the device driver's are installed on your PC

Start Odin

In Odin select PDA and select the recovery image (recovery.tar.md5)

Check that only "Auto Reboot" and "F. Reset Time" is set

Click on "Start": the kernel image should be flashed now and the device should reboot afterwards. By flashing the recovery, your warranty will be void.

After the recovery flashing process was successful, power of your device. If not restart into Download mode and flash again or flash the stock rom.

Before you flash:

You need the latest TWRP recovery (see above). Otherwise TWRP might not be able to flash the ROM. This is because TWRP checks now if the device is "supported".

Wipe the device to avoid problems with remaining files from the old installation (see instructions below). This also applies if you already installed an older version of CM 14.1.

Flash CyanogenMod:

Reboot into recovery mode (Press Volume-Up + Home + Power button)

If you come from a stock ROM, this is your opportunity to make a Backup of your phone(Backup, then select Boot, System, Data, then swipe to backup). Note that the recovery might fail to restore the backup when you want to go back to the stock ROM (for me it got stuck after a restore during boot. But the backup was made with a different version of TWRP, so it might work in general) - simply do not expect too much of it at the moment.

If you haven't copied the installation files yet, you can now copy the GApps and CyanogenMod zip to your internal sd or external sd (be careful not to put the files into the data directory of the internal sd card as this will be deleted in the next step). Be sure that MTP is enabled (inside Mounts, click on Enable MTP), then, from your pc, copy the files. If MTP does not work from recovery, try it directly from Android or remove the external sd card from the phone and put it into your PC.

Wipe Dalvik Cache, Cache, System and Data (inside Wipe -> Advanced Wipe). Do not report problems if you did not wipe those partitions as the problems are most probably related to this!

Install the CM ROM zip-package

Install the GApps zip-package

How to root:

No SuperSu is needed as CyanogenMod already comes with integrated root support. Root access is disabled by default.

You normally do not need root access. If you want to activate root access for apps, do the following:

Open the Settings menu, select "About Phone"

Tap on the "Build number" entry seven times. You should be notified, that the developer settings are now active.

Open the Settings menu, select "Developer options". Enable root access by selecting "Apps" in the "Root-Access" setting.

In case you want to go back to the stock ROM:

lf you do not have the latest ROM for the G800F you can download it from SamMobile

Reboot your phone into Odin mode

Open Odin on your PC and connect your smartphone with your PC via USB

If you have a zip-file unzip it so that you have a .tar.md5 file

In Odin click on the PDA button and select the .tar.md5 file. Then press "Start".

Normally the stock rom fails to boot as the data from CM is still on the data partition. So after flashing the stock rom, reboot into recovery mode (it looks a bit different now). First wipe the data partition, then wipe the cache.

Reboot

Developers welcome

At the moment the G800F/M/Y specific port of this ROM is only done by two persons (CTXz and hennymcc). Although Unjustified Dev also works on this ROM he does not own an Galaxy S5 Mini but a Galaxy Light which has a similar base but is different when it comes to camera, nfc and other components (maybe even slightly when it comes to audio and radio).

Help from other developers is always welcome. See the bug/feature section and this thread to see what is missing. Just give some short info (here in this thread or PM) that you want to work on some issue or feature so that work can be synchronized. Maybe there are also other devs that want to work with you on the same issue.

Knowledge in how the kernel works and good programming skills in C, C++ and Java would be nice but not necessary for all problems. At least you should be able to build the ROM and test your changes yourself but you do not need experience in porting ROMs.

Thanks to CTXz, Psyafter, spookcity138 and ayke for working on this ROM.
