[Bypass Anti-Roll Back Protection] Downgrade The MIUI And Android Version

MIUI10 for Redmi 5 Plus released with android up-gradation to 8.1 from 7.1. When some users got bricked their phones upon downgrading the android version then Xiaomi realized and informed it on their forum that the recent updates have anti roll back protection implemented by Google for enhanced device security.
Well its enough for intro of anti roll back protection, this guide is for users whom have addiction to change roms.
I go through XDA Forum and MIUI Forum I found that users downgrade their phones but the results are nothing except the boot-loop.
Lets move to the guide to safely downgrade your redmi 5 plus!​
Requirements:
Definitely Unlocked Bootloader
Custom Recovery
MIUI10 Dev 8.7.3 zip
MIUI9 Dev 8.4.19 or later fastboot rom
Process:
Download the 1st global MIUI10 closed beta 8.7.3 update and flash it using TWRP.
After flashing boot into system and check if your MIUI version is now 8.7.3 then boot the device into fastboot mode.
Load the MIUI9 Dev 8.4.19 or later in Xiaomi/MI Flaash Tool connect you device and select the "clean all" and click on flash.

A video could be a proof but at now I can't make that, this is a completely safe way to downgrade!

Thank in advance

I found it strange already because my previous rom was EU version. What's the difference between global and EU?

The Eu rom uses Google applications for contacts, calendar, calls, etc. and there is no recording of calls

Question LE2120 IN Version

So I bought a oneplus 9 pro from a dude yesterday for 500 bucks which is an absolute steal. I unfortunately however have the Indian version of the software (Oxygen OS 11.2.10.10.LE15DA)(Model: LE2120) so none of my 5g bands are working, which is the main reason I upgraded.
1.) Yes I know there's a very popular forum about how to flash the global version of oxygenOS but the thread gets posted in and updated constantly with different info from different people so it's harder to follow.
I need the following:
1.) Previous IN Oxygen build to downgrade.
2.) Current Global OxygenOS Version to upgrade.
I know doing this can wipe your data but the phone is a day old so I don't have any data. I can easily switch IMEI numbers through TMobile app as well so I'm not worried about that changing if it does. I just want the correct versions of the ROMS so I don't up/downgrade to the wrong versions and critically mess it up. Any help is appreciated and thank you!

If I'm incorrect with any of the information I provided please correct me as well. I truly appreciate any information on this topic!

Can you post your phone info, I got my from clicking on settings>about phone
I know you already mentioned it in the text, but a picture would help.

Flashing a global/europe firmware wont fix your 5G. You need to do some extra step and need to be rooted to get the 5G back. And 2120 it's Chinese version which comes with Color OS as primary but sellers found a way to flash Indian firmware there and flashed and sold the phone.
Below you will find LE15DA Indian downgrade to 11.2.5.5 link: https://oxygenos.oneplus.net/OnePlu...110_all_2107082121_downgrade_66a1f653e8ee4eb5
Downgrade to this and then install European firmware but wont get back 5G anyway try.

I want to downgrade my A5 2017 to Android 6.0.1 but I can't seem to find an official Android 6.0.1 ROM for the A5 2017.

I am not experienced at all with ROMs, so a helping hand would be, well, helpful.

the a5 2017 never released with android 6, only with android 7

It was released with Android 6 and then later got 2 major upgrades (from 6 to 7 and 7 to 8) like all Samsung phones at that time. Android 8 was the last official version that A5 2017 received.

Yeah Android 7 was already available at the time A5 2017 released, however Samsung decided to ship it with 6 instead for some reason that we dont know.

your best bet would be is to install twrp, format system, boot, data, cache all that stuff, and extract system.img, boot.img from a 6.0 firmware for the a5 2017, and then flash it like a gsi. this could be a hit or miss, as it wasnt usable on my j5 2016, as i didnt have wifi, but perfectly fine on my s9.
