No, Miui10 doesn't support replying to notifications (on LS), also it doesn't have persistent notifications (on LS). The reason being, Miui has still not fully integrated the notification capabilities from stock android OS. It might come in future updates, but nothing is a given.

Different hardware for cost cutting measures. Importing parts to India costs them quite lot. So its not easy to build the same device as china in India and price it accordingly. Specially when its on a latest flagship soc. And they have to keep the prices low or else Indian market would be furious. Even after all this, India isn't happy about K20 pricing.

If its two different set of hardware, its two different code name. I wish they would allow stock fw swapping between them with locked bootloader. But that also comes with another set of issues.

[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] aman2125:
The concerned device is a k20 pro (RAPHAELIN) indian version.

I unlocked the bootloader.

Installed Orange Fox.

Flashed Pixel Experience Plus.

Wiped cache/dalvik cache

Rebooted

..

The phone keeps taking me to fastboot.

I can boot into recovery by pressing the volume up + power button.

I can flash zips via all-in-one tool.

I have tried reflashing the indian fastboot rom as well as the global one.

But nothing seems to be solving the issue. It keeps booting into fastboot.

I'm sorry. I'm a noob. I tried following the tutorials but eventually ended up in this mess.

Any help would be appreciated.

My device is Indian K20 Pro (raphaelin) and not able to flash Pixel Experience Rom ([ROM][9.0][raphael] Pixel Experience [AOSP][r46][2019/09/06]), however flashing lineage-16 Rom worked.

Steps Tried:

1. Unlocked Bootloader (via miunlock tool)

2. Flashed chinese fastboot rom V10.3.17.0 / V10.3.16.0 (via MiFlash tool)

3. Reboot to bootloader and flashed TWRP recovery (twrp-3.3.1-13-raphael-mauronofrio)

4. Reboot to TWRP recovery and tried to flashed (PixelExperience_Plus_raphael-9.0-20190906-1038-OFFICIAL.zip) with wipe (data, cache, Dalvik, system)

but it fails with Error E3004: This package is for "raphael" devices this is a "raphaelin"

Not sure what else i am missing here.

fastboot getvar product says product: raphael

I believe flashing chinese fastboot rom V10.3.17.0 / V10.3.16.0 (via MiFlash tool) on indian k20 pro do change vendor and firmware right?

if not help me correct procedure to flash chinese vendor/firmware files.

Anyone else faced or resolved similar issue please help me out.

Pardon me, but am i supposed to flash a Chinese MIUI version before I flash any custom rom on this phone?

And there are so many versions of MIUI for this phone, can I flash each of them interchangeably? Or does it carry a chance of bricking the phone?

Also, I thought Xiaomi reduced the BL unlock time to 3 days, but to me it is showing 7 days.... ☹️
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Sukhi:
You just need to be on the Stock vendor firmware that shipped with your device. If you have India unit, then there is no need to flash Chinese MIUI.

All K20Pro / MI 9T Pro roms can be cross flashed. Just don’t lock your bootloader on any rom other than the one that your phone originally shipped with from factory.

Xiaomi Reduced the BL unlock time frame for Poco Only. Few of the devices stilk have 30 days wait period.

[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] ntmalol:
Quick question, why would someone downgrade from Q to P? Just wondering. Also why do so many people want to unlock their bootloaders? Doesn't it break the google play protect and prevents users from using secured banking and other paying apps?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Robbo.5000:
Q is still early days and so still has a few issues. Although Xiaomi have moved it over to stable, this seems to have been done as a pure marketing exercise, as its quality is still beta quality. Xiaomi just wanted to say they've released a Q build on the day Android officially released Q.

There are many reasons to unlock the bootloader. Some like the phone, but not the software and so want to install a custom ROM. Some want to root the phone, to remove more bloat and to have more powerful features.

Using Magisk as root and installing some Magisk modules will allow you to continue using financial apps and GPay.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Sukhi:
People try things for fun and when they realize that things didn't work out as expected on account of Q ROMs being in beta, they would eventually like to return to P. Technically, you loose safety net while unlocking the bootloader and you could easily get over it by using a Magisk module but unlocking has its own merits and demerits.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] maddy143ded:
My K20 pro is On latest stock rom. (10.4.8). Noticed a few things in daily usage.

1: Dual Sim reduces battery life by around 20%.

2: No Heat issues while playing Asphalt 9 legends for 2 hours straight...(Wifi)

3: While on 4G Phone gets warmer while playing Asphalt. Also Battery drain is noticably more..(20%+)

4: Sometimes Asphalt hangs due to network issues even while there is full network. Might also force close...

5: Dual Apps is Awesome....

Also people trying Custom Roms, there are very few custom Roms that are stable enough to be your Daily driver. I myself have come to love the miui interface and the host of features it provides by default.

Not tried anything in my K20pro yet but Tried a lot of custom Roms in the past(Since Huawie Ideos and Samsung Nexus S days).

Custom Roms rarely provide better battery life then Stock. They can provide better performance but again at the cost of battery life. MIUI itself is a custom ROM and has most of the features that other small developers add to their roms. Same cant be said for Samsung's One UI.(It freaking doesnt have an option to display network speed in notification bar).
