Xiaomi Redmi 1S might not be officially updated to Android 6.0 Marshmallow but that doesn’t mean you cannot experience the latest Android firmware on your device. It means only that further OTAs aren’t happening, but you can still add or install dedicated custom ROMs that can ensure a stable Marshmallow system on your own Redmi 1S. That’s why during the following step by step guide I will try to explain you how to install the new CyanogenMod built (CM 13) on your Xiaomi Redmi 1S.

CM13 isn’t yet officially available for the Redmi 1S, but thanks to those of xda-developers we can use a ported version of the same ROM. So, the devs modified and optimized the CM 13 firmware in order to bring a suitable Android 6.0 Marshmallow update for the Xiaomi Redmi 1S. Even though the update is not yet fully stable you can still use it on a daily basis and you can still test the latest features, apps and processes after completing this tutorial.

So, bottom line, with this CM 13 release you will get the Android M OS for your Xiaomi Redmi 1S but you will also experience minor software related problems like bugs and hangs – all the problems will be resolved by the devs soon, so you have nothing to worry about. Therefore, it is up to you: you can resume the guidelines from below for flashing the unofficial built of CyanogenMod, or you can wait for a more stable release of the same Marshmallow update.

If you do want to try it out, then first I recommend you to make a Nandroid backup. As pointed out, the ROM is not yet stable so you might not be pleased by what you obtain. So, in that case you might want to go back to stock. If that happens, a Nandroid file will be more than helpful – through the Nandroid backup you can save (and restore) the stock Android firmware that currently powers your Xiaomi Redmi 1S.

Moreover, since we are dealing with a custom ROM that isn’t related with Google, you can apply the update only in certain situations and only after preparing other additional operations. These operations are referring to the following aspects: you have to root your Android device and you have to install a custom recovery image (such as TWRP or CWM recovery) on your Xiaomi Redmi 1S. With root you will ensure an unlocked system and the recovery software will be used on the flashing process.

As you will notice, installing CM 13 is possible only if you first wipe the internal storage system of your smartphone. Therefore, you will have to hard reset your device and to clear its app data cache. Due to same reasons, you might end up in losing important and personal data. So, I recommend you to backup everything that you might use afterwards: contacts, call logs, texts, images, videos, audio files, market apps, internet settings, EFS, IMEI / NVRAM data, calendar info, saved passwords and so on – don’t worry, the backup can be easily completed as you can choose to sync your data, to use a cloud storage platform or several other backup and restore tools from Google Play.

Since CyanogenMod is an unofficial Android 6.0 Marshmallow update, flashing the software will void the warranty of your Xiaomi Redmi 1S. Yes, that’s right, after taking care of these lines you will no longer be able to reclaim your phone’s warranty. If something bad happens most likely you will have to learn how to manually fix your bricked Android device.

Being a manual update operation, this process will require the following: a computer, your smartphone and your phone’s USB cable; on your computer you will download some files, so temporarily disable antivirus tools; you will have to connect your handset with your PC so on your Xiaomi Redmi 1S gain Developer Options and check the USB Debugging option: go to “menu – settings – about phone” and tap several times on Built Number and then access “menu – settings – developer options”; charge your phone in case the battery power left is lower than 50% (if your Redmi gets turned off while you try to flash the CM 13 system, a soft brick might be issued).

Take note that this Android 6.0 Marshmallow based update is compatible only with the Xiaomi Redmi 1S. Don’t use the guidelines from below if you are using any other Android based devices.
