MU-MIMO - Redmi Note 8 Questions & Answers

Hello everyone.
Cannot find any relevant information about MU-MIMO technology on my Note 8T device...
Is it a hardware option or some software implementation by ROM flashing?
Thank you.

It's hardware related

will be blocked. Then I saw many threads about Qualcomm
And rsap issues.

J2 with Exynos 3475 working ROM with FM radio

Hello everyone.
I need help finding an AOSP rom for Exynos 3475 J2 2015 variant (I found that some models have this chipset, but I can't find which one) with FM radio working.
If there is nothing like that, ideas and code too will help me because I'm trying to develope a working kernel with FM radio support.
Thank you

Upgrading Bluetooth to 5.0 ¿Is it possible without hardware update?

My now rooted Xiaomi Redmi 7 comes by default with Bluetooth 4.2 connectivity, but as far as I know the Qualcomm Snapdragon 632 has support for Bluetooth 5.0, I've been doing some research and cannot find a proper answer to my question, also checked some similar posts to this one but none were the same, were all different questions, so I wanted to ask if it's possible to upgrade from Bluetooth 4.2 to 5.0 without any hardware update? or is needed to update the internal Bluetooth Adapter to actually update the Bluetooth Version? Thanks in advance, and sorry for any mistake that I may had.
no bro , hardware is required to upgrade to 5.0 and that too is not normally possible

Carrier Aggregation

Does redmi 6 pro support carrier aggregation ? The chipset does support it but i think xiaomi has disabled it .
Does it work in custom rom or Mi A2 lite ?
On cacombos.com this device is not yet listed so please submit your device log to cacombos.com/contribute so then could listed and see if it support Carrier Aggregation.
I think this device do not support well due limitation of RF. Example A2 have very limited support: https://cacombos.com/device/M1805D1SG

I don't know about mi a2 lite , but the stock ROM on R6P doesn't support it .my carrier supports it though . Chances are r6p doesn't have the additional hardware required .

Question Will cross flashing modems open up different bands?

Hi I have an LE2120 cross flashed to global and am currently running nameless. I was wondering if flashing a NA modem would allow me to see all the NA bands including the Verizon UW bands. I ask this since as far as I can tell the hardware is the exact same on all the models with just a change in software. I appreciate your answers. Thank you.
Hi, here is a link with more info regarding you question for/on our device.
