[Q] I have a mountain of questions before I decide to buy this phone :)

Hello everyone,
I have got a mountain of questions that arised from reading the forum and a lot of different topics.
I'll have numbers on them, so if you can/want to only answer a few of them you can refer to the number.
1. I've read about this ARB quite a lot, what's the deal with that if I want to go to a custom rom?
2. I understood that it matters where to buy the device in terms of an unlocked bootloader (TradingShenzen seems like a good place to start). But if I can't get my hands on a phone with unlocked bootloader, can I unlock it myself?
3. I'd like to go with the xiaomi.eu rom, any advice on how to get there? What I mean is, should I choose a CN model or is a Global model better, does it matter? What steps to take regarding TWRP and avoiding ARB, etc.
4. What does GSI stand for? I haven't found any thread explaining what that means, and I'm quite new to xiaomi devices (would be my first one).
5. I've also seen that there are quite a few different variants of this device, do the roms for it just work on all of them or do I need to check if the model is supported? (That seems to be a bit different to other phone vendors)
That's it for now, please don't kill me if some of the things have been answered before, I haven't found an answer to the questions so far (the infos that I got so far were insufficient)
Cheers,
Zacki

1 Google introduced ARB, a safeguard to not create an older version of the system from the currently released. If you install the official older version of the system for a new one, you will wall your phone.
Does not apply to Custom ROM
2 You can unblock the bootloader yourself on the official xiaomi website. It takes about 300 hours
3 unlock the bootloader, install recovery, install xiaomi.eu. Global rom is more stable, but xiaomi.eu has more personalization options. Recently, xiaomi.eu does not cause problems on Mi Max3, but it causes problems on other models.
4 GSI https://source.android.com/setup/build/gsi
5 Mi Max3 Global 4gb RAM 64gb internal memory,
Mi Max China 6gb RAM 128gb internal memory
You can install the Global ROM on the china version if you have unlocked the boootloader, and remember about the ARB. Otherwise, you will wall your phone
The Global version is popular.

Thanks for your reply.
@1. Interesting to see what Google is up to with things like this...why would they want this?
@2. Thanks, but whoa that's quite some time...and I guess I can only trigger the 300h AFTER I bought the phone, right? (Why so many hours actually...?)
@3. I've read about the changes they made to the rom and I like that. But what do you mean with being "less stable" than the global rom? In what way? I'd like to use that as my daily driver if I get it (not the weekly builds of course).
@4. Will have a look, thanks :good:
@5. I was actually looking at the 6GB/128GB version of the phone, if I can convince my wife to allow me to spend ~260€ on a phone (I'm currently a student ).
In this case, I'd already have an unlocked bootloader and if I want to install the rom from xiaomi.eu, there should be no problem, right? Also regarding ARB, this should be fine, right?
And in what ways are the CN and the Global versions different other than the rom? Are there differences for the supported bands or radios? I live in Austria, can I use the CN model here without any downside?
Edit: I'm having a look at this particular model, it would be available with CN firmware or with Global firmware. Would that still account as CN model in this case?

Google thinks people should use the latest system because it provides better security.
Xiaomi introduced a long wait time to unlock the bootloader, because dishonest sellers offered CN versions outside of China and India by installing the Global system on it. The CN version is only for China and India.
Xiaomi.eu provides its system every week. Contains various patches and additions. Sometimes something does not work, payments, BT paired in the car, notifications etc. In my phone, the last two versions do not work Gmail notifications. In today's version, people write that OK Google is not working.
If you unlock the bootloader, you can install xiaomi.eu. The ARB will be kept at the level of the official system you had.
The CN system contains only Chinese and English. It does not offer Google Play, it also contains full Chinese software.
Version 6/128 is only a CN model. If the seller offers with the Global system, it means that he has unlocked the bootloader and installed the Global system. You naturally lose the Xiaomi warranty.

So the xiaomi.eu roms don't have any of that ARB stuff, good to know. Could I technically install an older version of that custom rom without triggering the ARB or is that not possible? Just so I understand that.
And how is that with other custom roms? I've read in some threads that you have to make sure you have the correct ARB if you want to flash that particular rom, why that?

I'm not worried about the warranty but more about the specifics of the device. Is the CN model different in any way that it may not work properly with the providers in europe? Or things like that?
And sadly that vendor does not seem to have that version in stock at the moment, so I was thinking of getting the regular CN version of the device, that's why I'm asking

As for xiaomi.eu it does not contain ARB, but there are exceptions. If the phone gets an update to android 9 - xiaomi.eu must use the full original xiaomi firmware from ARB. The next versions on the same adroid no longer have files responsible for ARB.
Current level of ARB = 4 from Oreo to Pie. What you can not do:
to install MIUI9,
to install Miui Global on a CN version phone with a locked bootloader
block in the bootloader if you have Miui Global on your CN
install Miui China on a Global phone and block the bootloader.
Custom GSI roms do not have an ARB, you can install anything.
Mi Max 3 in the CN version in addition to the system and memory does not differ from the specification from Global. Will work in Austria.

So if I get the phone with Android 8.1 and I want to get MIUI 10 (Android 9) I need to update with the official rom and then flash the xiaomi.eu rom?
And while we are at that, if I buy the CN variant, do I have to upgrade to PIE with the CN official rom or can I also do this with the Global rom to get ARB to 4?
And what't the deal with the developer versions of the original roms? I've read something about them but would that help me in any way?

Ok but once the bootloader is open, why relock it anyway?^^ And I've read that on the xiaomi.eu roms you can not accidentaly relock the bootloader.

Working in Austria sounds good, but what exactly do you mean with "in addition to system and memory". The system and memory are different in the two versions and the rest is the same? Is there anything I should be aware of while using the phone?

it's not like that. You do not need to update the system. Xiaomi.eu is built with miui china developer extended to additional language translations, optimizations of softu for Europeans and a few additions that occur only in the Chinese version of the miui.
The whole system, firmware and kernel is miui china. If you install xiaomi.eu then you install the entire system, with the firmware and kernel. They are suitable for the android version.
You can have miui global Oreo and install xiaomi.eu Pie. Everything will be updated.
Miui Global is available in Stable and Dev versions. Dev-Beta is a development version released every week, contains the latest security, system fixes and errors detected in the Stable version, as well as new additions that are tested and do not always have to work correctly (like the development version of xiaomi.eu). As developers will correct detected errors, the stable version is created.
I just installed myself Global dev. I like it more than xiaomi.eu. Everything works so far. I usually use Global dev, and xiaomi.eu tests once in a while.

Some block the bootloader from ignorance or inadvertently.
When installing a new ROM by MiFlash, you have the following options:
install and block the bootloader (by default selected)
clean everything and install

the parameters of the telephone accessories and the frequency ranges of the network are the same. The difference is 6gb RAM, 128gb Internal memory and MIUI china.

Interesting, because I've read somewhere that the normal and the dev version are more or less the same, just that you have to use the dev version in certain situations to "unbrick" because of something with the bootloader (but I don't actually remember the details).

If you have an unlocked bootloader then you install twrp and flash xiaomi.eu

Using dev to unlock the bootloader affected old phones. Currently, it does not matter. Rom useful as well as Stable.

Miflash is used to install only official miui Rom, you use the rom .Tgz package
It installs through Miflash with the cleaning option. It does not leave garbage in the old system.

If you have xiaomi.eu then china rom does not matter.
You can look for a seller who offers a phone with downloaded xiaomi.eu or miui global - to choose from
in the past, the sellers offered the china version.

So last question for now (I hope ), if I decide to get the EU version instead, can I still unlock the bootloader or is that only possible on the CN versions?

I've just read in another thread that it is 720 hours that's full 30 days... I hope it's more the 300 hours you said but I fear I might have to wait a full month for that...
Can anyone confirm this number of hours?
Cheers

Usually it is 720 hours, but I checked it every now and then, after 4 days, this time has decreased by half.

It's 100% not decreased or changed it 720 hours. Unless you had a mi account before an unlocked a phone

That is an interesting note. I created an account a few days ago, when I ordered the phone. Does this already count as "having an account before trying to unlock"?

Redmi Note 8T

Hi people,
I have just purchased a variant of the Redmi Note 8, called Redmi Note 8T, which is basically the same device but with the long awaited NFC! This variant just launched in Europe.
In theory should be same device as the RN8 with added NFC (the SoC and other specs are indeed the same) so I wanted to share some info:
- MIUI 10.3.1, Android 9
- Model Name M1908C3XG, the same as shared by a leak on some websites
- The codename of the device is willow, the ROM has in its fingerprint willow_eea which confirms I have an EU version., but the Redmi Note 8 codename is ginkgo.
I have already applied for bootloader unlock (need to wait for a week) so soon I will be able try some things if somebody asks.
I hope modding will start soon

I bought too, but waiting for delivery yet..

Hi, i got the Note 8T too, and i got a little problem.
Does yours have a notification LED? Cause i dont have any working on mine, and It seemed to me that the "normal" Redmi Note 8 has It.
So i wanna ask if is mine broken or if it is a downgrade from Redmi.

Me too..... where is?????
All Note have it... possible note 8t not implemented???
I not found it.....

In reviews on web writes, this model dont have led notification ..

Yeah guys, there is no notification LED on this device, what a bummer.

Redmi Note 8 has a led notification
Redmi Note 8T doesn't have it
Sent from my Redmi Note 8 using Tapatalk

Ohhh.sh..t....
The redmi note 8t is. Areally good phone but the notify led..... Oh.. when i bought I havnt thought....

Hey, I just ordered the phone too, how is it looking with the dev.?

The first OTA has been released for our device. I've grabbed the URL, it's MIUI 10.3.5.0 and can be installed only if you are on 10.3.1.0 which is the only version (so far)...
https://bigota.d.miui.com/V10.3.5.0....PCXEUXM-V10.3.5.0.PCXEUXM-d79044d785-9.0.zip

The first EEA ROM: https://mirom.ezbox.idv.tw/en/phone/willow/
https://bigota.d.miui.com/V10.3.5.0...EAGlobal_V10.3.5.0.PCXEUXM_e2b2a958aa_9.0.zip

I hope xiaomi.eu will support the 8T. No Miui 11 for now?

Fun fact:
In Camera information, codenames start with ginko. We knew cameras were the same, but that's something more.

Hopefully with just minor modifications, 8 development will work on 8T. I've got 14 days still to wait to unlock though.

Best custom rom for Redmi note 5 pro whyred

Hi guys
I would like to ask if possible help me with unlocking, rooting and helping me decide which custom rom to install on my Redmi note 5 pro.
I been off for sometime from xda, so bear with me.
Many thanks

Pixel experience plus (Android Pie) is the most stable and fast custom ROM I have tested
Unlock bootloader by the official Xiaomi application (backup your personal files because this operation will erase all phone data)
Install ADB drivers for Xiaomi device
Flash OrangeFox recovery 10 for Whyred
Wipe cache, system and vendor partitions
Install downloaded ROM (fromixelexperience.com)
Use "How to..." On YouTube to search detailed videos about flashing pixel experience (or any other custom ROM) on Redmi Note 5 Pro

Advising on a ROM is going to be hard as there are soooo many. A lot seem similar when reading them but may have a unique feature or bug. If you are able to change ROMs often then just try them out and swap between them. For me I use my phone for work. I rely on email and some apps. I also need GPS /maps and banking apps to work so I have a ROM that suits. It's an older ROM using 8.1 and I would like to upgrade but can't risk bugs.
To unlock the bootloader you need the official Xiaomi unlocked and sign up your account. Takes a few days or used to anyway.
Once unlocked just install your ROMs the usual way

You can switch from chinese to global rom(or indian rom if you want inbuilt call recording option) after unlocking bootloader and debloat it all after rooting..Or maybe just flash custom roms .

Hello Robert
I have ordered CN version Oct, and i have been using it ever since. Out of the box you will get 18w charger with adapter which is very good, i live in Bosina, both sims are working fine 4G works too. There is not much to be worried about in CN version it works great it gets latest builds of MIUI (compared to other versions). Only thing that was kinda a nitpick and kinda annoying for me from start is that you get few standard Chinese apps that you can delete, and some of main Mi apps keep giving notifications in CN like mi videos and very other few, but rarely and they can be blocked. When you power on a device for a first time and creating Mi account you will have to install gapps which you can do over integrated mi store as i can remember (just type google no need for Chinese fonts). After doing that and logging into your google account i recommend you to unlock bootloader, you will have to make a request for unlocking it takes 160+ hours for it to get approved. Install xiaomi.eu rom which is cleaned and optimized CN miui for global users with xiaomi devices and regular updates and builds. I am currently using xiaomi.eu rom its fast, it has also ability to update it with updater in system. Anyway it is up to your preference what you want from device, you can try to install global firmware without unlocked bootloader you can try, if you want or some other custom rom with unlocked bootloader.
Best regards

Question How to I switch from global MIUI ver. to CN ver 12.5?

Because of the recent pandemic, i couldnt go back to china to get the Redmi K40, so i had to buy the Poco F3 in hong kong. after watching some bilibili videos about 12.5 (some were negative, but i dont really care), i realized im missing out on quite a lot of content and features. Now, before you say "Oh if I were you i'd just go for xiaomi.eu" i do prefer xiaomi's AI way more than google assistant, so thats one of my main reasons for going CN. but how do i actually get there? I went to the CN xiaomi community page for the rom download but something is wrong with the page, and twrp doesnt support K40 or F3 as of now either. I do see the alpha build for twrp in this forum, but is that good enough? the image is what the xiaomi community site shows when i click on rom download, i also couldnt find the 12.5 rom for k40 anywhere else.

Here better? xiaomifirmwareupdater.com
I think I saw it there... I'm waiting for my K40.
