Try both and enjoy. Why limit to one ROM
Stock ROM is somewhat stable
With custom ROM you will get android pie

Just flash ROM and gapps and don't flash firmware while flashing custom ROM
While flashing stock MIUI ROM use fastboot ROM to flash and there won't be any chances of brick. MiFlash software checks bootloader index before flashing a ROM so it is safer way

You can also use latest recovery ROM and flash it using TWRP recovery

So Finally installed GCAM after unlocking the bootloader , installed Redwolf recovery & rooted with Magisk & its working good. Will i be able to upgrade to MIUI 10 with OTA or have to follow some other process?
Also, which ROM & kernel setup do you use.
Thanks in advance!

Yes you can upgrade to MIUI10.. but you have to flash full recovery ROM, still you will get OTA update from xiaomi but its always recommended to flash complete recovery ROM

If possible then how to revert back from MIUI 10 Pie to MIUI 10 Oreo

Hi all
My note 5 pro is Global ver, 6gb/64gb. I was on Oreo last ver, just before few days I received notification for Pie, so without a 2nd thought I downloaded and installed that. The Pie ver is stable 10.3.1.0 PEIMIXM and now regretting why I did that. The battery drain is horrible, it drains like crazy, on Oreo my battery used to last at least 2 to 2.5 days whereas this one just dies in 1 day, the usage is less then the previous usage in Oreo.
Now the question is how can I revert back to Oreo from this Pie, if at all possible.
The phone does not have TWRP but the bootloader is Unlocked.
Any help is appreciated.

Download oreo fastboot file and flash it with mi flash tool(select clean all if u want to keep bl unlocked)
U can flash recovery rom file and flash it via twrp.but fastboot flash is recommended
Will this not brick my phone as trying to go back to previous ver of ROM.. and due to this Anti-RollBack policy?

its been awhile since i have flashed anything on a phone. last time i did it was on my note 4...anyways, i also want to do this since my battery doesn't last long and dual apps for Pokemon Go, isn't working like i had it before.
my bootloader is locked. I know i have to unlock it via MUI website and write the reason i wan to unlock it. how long does it take for them to unlock it?
what should i write to them?
does unlocking the bootloader mean its rooted or do i have to have a custom rom?
also, im confused on what model my phone is. i checked my model name: its M1803E7SH
i checked online and it says that its the redmi note 5 as well as the redmi note 5 pro..so im wondering if this method will work on my phone. pleaaaase help

You dont have to write any reason to unlock bootloader.
visit en.miui.com/unlock page login with your mi account and proceed with unlocking procedure, you may need to wait 360 hours before unlocking bootloader (depending on your mi account activity)
your's is Redmi Note 5/Pro model name WHYRED. you can download Redmi Note 5 Pro ROM package and flash it on your mobile

Anti-rollback Help!

Hello everybody,
yesterday I installed the ROM V.11.0.7 but it doesn't make any changes. It seems official. It's terrible! Today I tried to put the V. 11.0.5 but it does not even let me install the TWPR 3.4.1B I probably made a mess.
It doesn't allow me to downgrade.
Can you help me please?
Thanks a lot!

To come back to miui from AOSP you must use miflash tool to flash an official fastboot version of miui. It's necessary because miflash restores some partitions that are altered by flashing AOSP roms. Just remember not to relock the bootloader because miflash can do that.

You must bind your mi flash to your account to be able to use it to flash a rom on your phone. Note that mi flash will recognize your phone even if you had flashed a different rom on it.

Question Flash official redmi k40 firmware on poco f3 via fastboot ?!

can you please answer me , if i can flash the Official Firmware (enhanced edition 12.5.6) of the Redmi K40 on the Poco F3 using Mi_Flash_Tool with unlocked bootloader in Fastboot Mode ?!
Thanks in advance
i cant see any issue as long as flash all & lock is not selected. Why not just install Miui vn or Eu they are based on china.
Yes you can but dont lock bootloader.

The ROM miui vn is also the enhanced edition i believe. Regarding flashing the official once via mib flash in sure it's fine as long as you don't lock bootloader with it.

If u lock bootloader after flash, the motherboard crash because not same region that he configurated. So if u let him unlock bootloader, ure device won't think about region and let u boot into ure china rom

it is not about the motherboard , it is about the bootloader because it the system check for your device and its security , it does not crash it will not boot because the bootloader cannot accept such system to run on that partition except the official one for the motherboard
So, it is mandatory to unlock the bootloader even when you are flashing stock firmware?
Just don't lock it again with other firmware?
I'm currently using Global MIUI 12.5.4 version but was thinking of flashing Mi 11x firmware.

No, It only applies here where the firmware wasn't made for the device but if you're going to flash a stock firmware that was made for your device the you don't need to unlock it
