Hello all, I'm completely new to the MIUI world (I recently bought the Redmi Note 11) and this is my first time using a Mi device. So I ask for your understanding.
I just have some few questions regarding this rom and how to install it.
1. Can I install this on top of the stock rom without losing my data? (installed apps, settings etc)
2. Will this trip the encryption/warranty of the device? (like in samsung, the knox thing)
3. From the download links for my device, whats the one I need to download if ever I decide to install this ROM?
4. Do these roms also have the latest security updates by google?
Thank you all in advance.
1. Not. This is custom ROM (be aware) and as that you must first unlock Bootloader. Unlocking the Bootloader procedure performes Factory reset. Please search here on the Forum and elsewhere on the Net and YouTube how to unlock Bootloaders on Xiaomi
Also, first time you will be flashing Xiaomi.eu, you will have to Factory reset. Later Xiaomi.eu updates will not require Factory reset. But switching back to stock or any other custom ROM will again require Factory reset (every time you switch, but not when you update - generally about switching the ROMs, nothing specific to Xiaomi.eu)
2. AFAIK, with custom ROM (as it is), you could not excersise warranty. But you can always flash back the stock firmware and relock BL and then go for the warranty - unless you brick the phone (but if you brick the phone by not properly following the procedures for flashing a custom ROM, that's not for the warranty anyway)
3. Carefully read the OP post #1. Particularly, find your model in the table and (you can use this ROM only if your model is listed there). On the Download server you will see firmwares for all supported models, and for some more than one firmware (latest and some older version numbers). Choose the proper firmware file name, and usually you would like the highest version number.
As everybody else, you should be able yourself to recognize and download the proper file based on that
Additionally, some firmwares are Fastboot type (they have fastboot in the file name) and some (newer ones, from the moment when custom Recovery became available for that particular device) are Recovery type (they don't have Recovery or Fastboot in the name).
Read additionally in the post #1 and in this thread (find the posts with the link where to find the appropriate custom Recovery for your model and how to install) about different installation procedure for Fastboot and Recovery type of Xiaomi.eu ROMs
4. Security patch is of course the latest from the time when the particular firmware was built (on Download server, you can read when each file was uploaded - when you install you will see in the Settings the Security patch date). You can later receive Security updates from Google
Whenever Xiaomi.eu Stable updates for your device you will receive a notification), it will come with the latest Security patch
Unlocking procedure, from the moment you request, takes one full week (exactly 168 hours) by Xiaomi to let you unlock. Enough time to google, read, learn...
