help on flashing custom ROM - Xiaomi Mi Pad 4 Questions & Answers

hi everyone, i just ordered a Mi Pad 4 wifi version and according to the seller it is using Global Rom which i assume it is already bootloader unlocked.
i wan to flash carbon ROM on my Mi Pad 4, may i know what is the actual procedure if the bootloader is already unlocked?
1. do i need to link my Mi account first before trying to flash carbon ROM?
2. if it is already bootloader unlocked, do i straight away flash the ROM using the instructions in the carbon ROM thread or are there anything that i need to do first?

Unlock question

The official bootloader unlock guide here http://en.miui.com/thread-202290-1-1.html states that "If you're using Redmi Note 3 Qualcomm version or Mi 5, you can unlock on MIUI Global Stable ROM"
1- Did anybody succeed in doing so?
2- After unlocking the official way, can I still flash the latest global stable? (assuming that point 1 is not possible and I have to flash the china dev) I read warnings everywhere not to do so to avoid boot loop, is this warning valid even when unblocked through the official way?
3- If I flash the latest global, will my bootloader get locked again?
I would like to unlock my bootloader to prepare for CM13 and in the meantime I want to keep running the global stable ROM.
Many thanks

I'm on Redmi Note 3 Qualcomm.
1 - For me, it only worked with the Global Dev ROM. You can switch from Global Stable without erasing any data though. I had the usual "never works on the first try"-stuff though, so I tried a lot of things and I can't say if being on Global Stable was one of the main issues.
2 - I read similar things, but also that you can OTA update without any problems when you are officially unlocked. I think the posts warning of bootloops concern the unofficial unlock only and it will happen if you forget to delete emmc_appsboot.mbn before flashing an official ROM.
3 - Shouldn't happen. Haven't tried it yet, but what would be the point of Xiaomi locking the bootloader again, just because you changed ROM versions.
So, #2 and #3 is guess work on my site. Hope someone else can chime in and give definitive answers. As of #1, hope it helps to know that Global Dev works fine. Or was there any reason you wanted to stay on Global Stable?

[HELP] Flashing TWRP on MIUI 7.4.9.0|LHOCNDD (Vendor ROM), BOOTLOADER UNLOCKED!

I got my kenzo yesterday and was surprised because it's already unlocked. My problem now is how to flash TWRP, since there is 2 methods which involves a bootloader unlocked via the official/unofficial method. I don't want to install official MIUI because it will re-lock the BL, plus what I want is a AOSP/CM based custom ROM. Please help!
**I got this Note 3 from an online retailer. They said their supplier is the one who unlocked the device. The retailer doesn't know if it is unlocked officially or by the unofficial method.

[SNAPDRAGON] Downgrading the Redmi Note 4

Hello everyone..
I recently got my Redmi Note 4 SD, its the 4/64GB variant and the device is classy I must say. However, since the last update, my device is having RAM issues and above all, heating issues. What I'm trying to know is can I flash the outdated version via fastboot method without unlocking the bootloader?
I am on the 8.1.15.0 version (Indian Variant) and I have the 8.1.10.0 version, I just want to rollback to it.
I hope there must be a way to flash stock ROMs without unlocking the bootloader. And also, if I unlock the bootloader and flash the stock ROM, will the bootloader get locked again or would stay unlocked?
A step by step guide would be highly appreciated.
ThankYou
Isn't there anyone who can help me out with this?
You need to unlock bootloader to downgrade or flash fastboot ROMs. You cannot downgrade from Updater app

Kidnap the seller and torture him until he remembers that mi account. I did it before someone, it worked.

As far as I know you can´t cross the firmware before to unlock device and in your case when you unlocked it you can flash any of both but you can´t relock it over the crossed firmware or you could brick it.
If you want to wait that someone that tried it can confirm it but I read that some users bricked due to this.
