You can use Odin even if the phone is rooted, it doesn't matter. But if you want to use something else (heimdall etc.) then you can just unpack the tarball using any common packing software - e.g. 7-zip or winrar.

Very first thing I did after downloading everything was VolDown + Home + Power to boot into Odin. I get the confirmation screen, accept that, and then an Android logo and "Downloading Do not turn off target !!"

What's going on? Should I just wait? There's no indication that anything's actually happening.

When its in that mode, is when you have to use Odin to flash the recovery, from where you can wipe everything and install the ROM..

What I figured out was that "use Odin" means "launch the Odin desktop app". It's very confusing because that screen on the phone also says Odin. I am in the process of pulling together a screenshotted step-by-step guide which I will post here when it's done.

The Hall sensor is the compass, I think: https://en.m.wikipedia.org/wiki/Hall_effect_sensor
I made it work by rotating the phone twice over each of its three axes after a reboot: that's a way to recalibrate the compass. Otherwise it has been very stable in my experience, apart from YouTube and the camera crashing occasionally (now I'm using CM13, which does not have these issues).

It isn't. Magnetometer is the compass, Hall sensor is usually used with accessories like SView cover, it detects when the cover is closed because there is a magnet in it.

Sadly the Devs don't give a f*ck about them bugs and left us with a unfinished version. Camera bug and slow Charging make this ROM useless. I'm waiting for the official release from Samsung.

You should be careful what you say. Don't forget: they are not paid for doing this. This use their freetime for making us happy with updates. Furthermore there are a lot of supported roms like slim 6 which have less bugs and are still in development.

    This is a CyanogenMod 12.1 ROM for the Exynos3470 based Samsung Galaxy S5 mini (G800F/G800M/G800Y). Support for G800M is untested so far.

    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.

    Working features
    • Receiving and making calls
    • Hardware sensors (Light, Orientation, Compass, Proximity, Acceleration)
    • Audio
    • Bluetooth (audio in HFP seems to be distorted with at least some headset devices)
    • Wifi
    • HW accelerated GUI
    • USB-OTG (Keyboard, Mouse, USB-Audio, Mass-Storage)
    • Camera (pictures+video: Back+Front)
    • MTP storage
    • IR
    • GPS
    • NFC

    Non-working features:
    • Fingerprint scanner (no app for tests found)
    • Pulse sensor + Step counter (no app for tests found)
    • Hall sensor
    • SELinux

    Known issues:

    Disclaimer:
    • You flash this image at your own responsibility. I am not responsible for any damage that might be caused by flashing this image (bricked device, lost data, ...)
    • Flashing this kernel image will trigger the KNOX counter, so your warranty will be void.
    • Applications that use KNOX (e.g. "Private Mode") might not work anymore when returning to the stock ROM, as the device is regarded as compromised. Do not flash this ROM if you need those applications.
    • The image is only for Exynos3470 based S5 Mini variants SM-G800F/M/Y.
    • It might be instable, crash your device, drain your battery, or even might damage your smartphone (e.g. if an USB-OTG device drains too much power)
    • Some users reported that their touch-screen stopped working permanently after some weeks of usage. For some user's (two at the moment including me) NFC stopped working permanently. Probably this issues are not related to this ROM as also many stock user's complain about hardware issues (random reboots, black screens, unresponsive touchscreen) but you have been warned.
    • Backup your data before flashing and check if the original firmware is present (e.g. at SamMobile)
    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:

    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 12.1.

    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 12.1 ROM zip-package
    • Install the GApps zip-package
    • Reboot the system and enjoy a Lollipop

    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 CM12 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 one person (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 Unjustified Dev from Team Regular. As the S5 mini (G800F/M/Y) and the Galaxy Light are quite similar we worked on this together.

    As you can see I am compiling on my laptop since I am staying at my friends for vacation so compiling will take longer especially when I have the sources on my external HDD
    13
    A new untested build is available here:

    Same disclaimer as before:
    As this is untested, bricking your device is possible. It is also possible that the ROM does not boot at all.
    Report problems in this forum.
    12
    After a crap ton of patches @hennymcc and I got our first compile done. I will try to flash mine once my compile is done.
    12
    Compiling CM 13 at the moment, wish me luck. If I get it to boot there might bee some bugs from before since I will add patches later
