LTE doesn't work with AOSP ROMs - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hello guys, (K20 Pro 8/256, Chinese varient)
So I've tried all Q ROM based on AOSP, and my data SIM card doesn't work with all of them. AFAIK, the LTE band being used is B3. Flashed all vendor/firmware that I can found (Global/Chinese/India/etc). Anyone know what's wrong?
Many thanks.

The 4G LTE in Miui is fake, check with devcheck

LTE+ problem

Hello,
I have a Mi 8 in Germany with Vodafone but the LTE+ does not work.
LTE works but very slow.
I have root and the Global MIUI 10 installed.
Can I go to Havoc OS to make it work?
Can I flash only Havoc OS and Google over the Global MIUI 10.0.2.2?
Did you check your APN ?
you can find it under settings>mobile network>APN (Access Point Names)
and choose for live.Vodafone or the carrier you have.
Yes the LTE works but not the LTE+. In the APN are web.vodafone.de active.
Mi8 doesn't have B7+B3 aggregation so sometimes in certain areas LTE is really slow
Ok but my Mi 8 never use LTE+ only LTE

It's only supported if you purchased Vodafone Red S, M, L or XL
It doesn't work with CallYa

Mi 9T PRO - K20 PRO Cross compatibility

i have the doubt if the Custom Roms from K20 pro Raphael (especially AOSP ones) will be compatible with Mi 9t Pro Raphaelin, like the times of kenzo and kate from redmi note 3 pro.
why would they not be compatible tho? the hardware is exactly the same?

The Mi 9T Pro is raphael_global.
Custom ROMs are compatible between the Chinese and Indian versions.
Custom ROMs for the Mi 9 (very similar hardware to this) are compatible across all versions.
Custom ROMs for the K20/Mi 9T (only the SoC is different to this) are compatible across all versions.
So why would you think they won't be compatible for this phone?

actually they are the same K20 Pro and Mi9T Pro
if you compare with kenzo and kate (i personally own them)
there are a few hardware difference in them like signal band, etc
i always wondered what the actual difference is, because it just supports different bands. Does it have a different modem or are the different bands just achieved with a software change?

The modem is the X24 that is baked onto the SD855, there is no separate modem. As far as I know the bands are set in the baseband partition, but this seems to be locked and cannot be simply flashed over. It needs proprietary Qualcomm software to change what bands are enabled.

do you mean modem partition? or some other partition?
imagine if we could unlock global bands, we could just buy the cheaper chinese version and have global lte bands

Cannot get VoLTE working in any ROM :(

Hi,
I cannot get VoLTE working in any ROM. It did not work in RR, it did not work in Havoc, it did not work in Stock MIUI and it does not work in LineageOS. So probably not the ROM is the fault.
Further Information:
Redmi 4X Global 3/32 GB
LineageOS 16.0-20201007-NIGHTLY-santoni (but did not work with other ROMs either)
German Klarmobil SIM (Telekom)
VoLTE with the same SIM works out of the box in my father's Redmi 6A
VoLTE is enabled in settings
Baseband: MPSS.TA.2.3.c1-00395-8953_GEN_PACK-1_V048

[Question]Mi 9t Pro Originally - Am i able to enable NFC on Indian Rom? (K20 Pro)

Originally Mi 9t Pro "Global" (With NFC)
as known, the indian rom for the K20 Pro doesn't support NFC. i want to use it as it combines all what i need from the three roms (China, India, Global) except for the NFC.
so is the any work around or some hack/third party app to force enable using NFC on it?

Nothing can be done, NFC is physically missing from Indian phones, so Indian MIUI ROM reports it's missing. You would need to hack the MIUI code itself to enable it. Try using a xiaomi.eu ROM instead and see if that covers everything you need.

I hate custom roms, wished there's a solution other way.

Question Mi 11 Ultra - Which Version to buy (EEA or Global)?

Hi,
I am planning to buy the Mi 11 Ultra but I am not sure which version to get.
Since my provider (Telekom Germany) uses a 4G frequency the Chinese version does not support I could only take the global hardware version.
But as far as I have read on this forum an remember from my Mi 9 back in the days there are two different firmware versions. The normal Global and the EEA (European) version.
On my Mi 9, I remember that the Global firmware got updates faster and had a few more features than the EEA one.
Since I use some banking apps which require a passed Safetynet check I would like to avoid unlocking the bootloader to switch to the global firmware.
Has anyone already some information on which version to get and if there are differences when it comes to 5G Dynamic Spectrum Sharing support? Either I could easily order the EEA one directly from Xiaomi Germany once it is available or would have to import the Global version.
Thanks in advance for your help and recommendations.

Simply, there is no EEA version of mi 11 ultra as stock, EEA firmware is not official firmware to be released out of the box and it extracted from Chinese version.
I had your thoughts as well until someone corrected me.

No, I think you are confusing EEA with EU.
EEA is an official ROM, but does appear to just be a later global version.
This is the official firmware list: https://xiaomifirmwareupdater.com/firmware/star/
Europe is the EEA version.

Are you sure you do not mix up the xiaomi.eu ROM (which is a rather unofficial firmware based on the official China ROM) with the official EEA firmware, which is also listed on the official firmware list for the Mi 11 Ultra here in the forum?

I'm on Vodafone Germany with a CN Mi11U which is working nice and fine, not sure which 4G bands Telekom uses, though.
If I look at the specs the CN version actually supports more bands than the EU version with the exception of B32 and B66 which is EU only....

The CN Version should in general also work fine for Telekom Germany even though they plan to use B32 to increase the download speed in some areas.
But I am also not really sure how the 5G Dynamic Spectrum Sharing (DSS) compatibility of the CN Version is since it lacks some 5G frequencies (like 900Mhz) used as anchor bands for 5G by the German Telekom. Especially since my coverage at home is 5G with 900Mhz as anchor band I do not want to risk getting the CN version.
Hi, so Antoine got an answer ? Xiaomi finally released the 11 Ultra in Europe with EEA firmware, so witch one to buy of GLOBAL or Europe model ? What's the difference between these two models ?
EEA is likely to be at standard price, whereas Global can be picked up for a lot less (when it's in stock)

Since the hardware is the same on all of them, why not order Chinese model, which will cost less, imiort it and unlock it 9unless it is unlocked already and flash it with either the EEA or Global rom?

I tried global rom and eea rom and eu rom on my device.
1)eea rom: I did not like photo quality and colours of eea rom.Especially in reverse light, white shadows in dark areas. Because good camera is a must this is not an option for me. So decided to choose between global or eu
2) I tried eu rom, i liked double tap to wake,sleep, ram usage indicator,call recording etc but did not like call sound quality(worse than global rom), bluetooth sound quality (worse than global rom), randomly freeze clicking some applications(worse than global rom etc.) , swipe to turn off etc. It is clean but extremely clean, i could not find some basic stuff like clockwatch etc
3)I tried global rom, i liked its smoothness (better than eu),i liked Camera(better than eea, same with eu), i liked bluetotoh sound quality(better than eu), i disliked no recording calls option, double tap to wake on home screen not working
As a result i decided to use global rom because camera quality,bluetooth audio quality, call sound quality,smoothness are crucial things for me.
I turned of all updates because any of the devices bought before with xiaomi brand was messed up by software updates, elder mi phone,robot vacuum cleaner etc

Is there a reason you need to use the default launcher? If it's about gestures, then with root you can use a mod for fixing issues on 3rd party launcher
