Fingerprint Scanner/Firmware issue on custom ROMs - Xiaomi Redmi Note 7 Pro Questions & Answers

As per title. This was an RN7P bought in China, but I unlocked the bootloader and flashed the MIUI Global/India version (11.0.5.0 PFHINXM Stable), which currently has firmware/baseband version 4.3.c2-00022. On MIUI the finger print scanner works absolutely OK.
On the other hand, of the custom ROMs I've tried: PE, LOS, Havoc, Derpfest - the fingerprint scanner does not seem to work. There is no option to set it up in initial setup or in settings later on.
I have tried flashing various firmware packages from xiaomifirmwareupdater, none of which seem to work. Some help here would be great!

Flash, China firmware 9.9.3 and then flash Custom Roms.

I should flash this on top of global/Indian MIUI? Any reason why this works, whereas the other ones don't?

As an update: having flashed the China firmware 9.9.3, the option to add fingerprint unlock still does not work.

Redmi Note 5/Pro Miui ROMs without firmware [fw-less]

Redmi Note 5/Pro Miui ROMs without firmware
We all know that Xiaomi added Anti roll-back to latest Stable/Beta ROMs and many users bricked their phones because of it, check my thread about ARB Here, then check out this one
Here ill provide Miui ROMs fully stock but without "firmware-update", to prevent any potential bricking while switching between Miui Based ROMs
Download Folders:
Here
Notes:
After flashing any of the builds above you cant go and flash FULL Miui ROMs to downgrade, just stick to my modded versions if you want to use older MIUI builds
No matter which Anti (3/4) you have, you can flash any of those ROMs with TWRP
Those ROMs doesnt affect your phone bootloader in any way, so you can roll back to your old ROM after Flashing any of the above builds
Old builds might get removed, so keep what you need locally, we will keep the latest 3 builds from every branch
Dont answer with false info's, i saw more than one reply with false statements
Be Nice to each other, no need for flaming in here
Dont post links to other ROMs here, i saw miuipro & eu links couple of posts back ( it could come with fw/bl)
Read OP, Search before posting
One more time, those ROMs wont remove or change your anti, if you come from anti 3 it will stay anti 3 after flashing, and same goes for anti 4
Again, if your phone is anti 4, you cant just simply go and flash FULL older ROM, even after flashing Modded builds, so stick with my builds
Anti 4 users can flash any of those builds just fine
[*]All the notes Above applies for My Modded builds only, do go and share it as facts for all Miui ROMs

Note for CN Users
Note for CN Users:
before flashing any Global ROMs, you guys have to flash Global Cust from fastboot
Download Global Cust Here
Donwload dummy.img Here or attachments
then follow these steps:
Flash dummy.img from Fastboot to Enable Fastboot Commands
fastboot flash antirbpass dummy.img
then Flash cust-global.img
fastboot flash cust cust-global.img
Then Reboot into TWRP & Flash Global ROM
and this thx

No!!, read notes please, those builds contain system, boot & vendor only, doesn't have anything to do with bootloader or anti
Wait for Modded Miui 9 builds!
?
Excellent thought. Keep it going!
Stable builds are UP!!
Enjoy
Thanks! Are these flashable through updater app? I mean since I can't flash official v9.5.17.0 global over v8.7.5 beta now as we have newer stable version 9.5.19.0 with ARB which I don't wanna flash yet. Also I have locked bootloader still 165 hrs to go until I can fastboot flash and downgrade but i really wanna go to stable ROM asap.
@AL_IRAQI
Hello, I am currently in an AOSP and TWRP installed, I am wanting to install to EU 8.7.12. If I do, can I go back to an AOSP again?
Obs: I read the notes but I still have doubts

Downgrade from MIUI 10 Global 9.2.15 Beta possible?

Hi all!
I'm running the mentioned ROM at the moment and I'm having several problems (GPay not working, Netflix not working, ...) so I want to go back to a standard MIUI version.
Can I flash the official global ROM via TWRP on my device? Or won't that work or brick my device?
Otherweise can I flash any custom ROM like Pixel Experience or Lineage without any problems over the actual ROM?
Hi. yes you can install the miui rom via twrp. we must take the version in .Zip and not that of fastboot. then if you want to use gpay, you must reblock the bootloader. me, I would prefer to use miflash to install the original rom and it also allows to reblock the bootloader by checking the box.
With relocked Bootloader, I cannot install any other Rom like Pixel experience or Lineage, correct?
I GPay only working with Stock Rom?

yes, if you reblock the bootloader, you could no longer install custom rom. it will unlock the bootloader again. but if you want to use gpay on a custom rom, you have to install magisk.

Trying my 1st custom ROM

Any recommendation on which ROM should i use for my 1st custom ROM? Is the pixel experience any good? i mean is there any major issues about this ROM? Is it also safe to flash it on my current MIUI version whihc is MIUI 10.2.2.0 PDGMIXM its the global version. I already unlocked my bootloader and currently searching for tutorials on how to install TWRP and which one should I install in this device. Many thanks in advance if anyone responds on this post.

It depends on how many costumizations you prefer. LineageOS and Pixel Experience do not have many extra features, while e.g. RR, Arrow and Havoc do. I experienced very few bugs in PE and LOS, but I haven't tried other custom roms. LOS has very clear installation instructions, which are also applicable to most other custom roms: https://wiki.lineageos.org/devices/polaris/install
We have an official TWRP version; you can find the instructions and download link on https://twrp.me.
Thanks
I just want to try a new look on my phone. Ill install those roms soon, is it ok to back up this current miui im using if i dont like the rom i installed right?
Yes, but some users (including me) reported failures of restoring full rom backups. So make sure you also use some alternative backup (e.g. the Migrate app) and save your backup files on an external device.
Use a full backup with TWRP. It worked for me every time. However there is a bug with phone protection (unlock code or fingerprint) - and you have to delete it manually in TWRP file manager.
But everything works fine.

Pretty much easier is removing any PIN or fingerprint authorization before doing the backup.

Not sure I get you. My apologies. Removing any PIN, fingerprint authorization before doing twrp backup is inevitable unless you want to modify your backup file the way somebody above described.

btw, does unlocking the bootloader affects my phone from getting OTA? im still using the stock rom now MIUI 10.2.2.0 PDGMIXM.

You can still receive OTA updates on the unlocked bootloader as long as you are using official Mi rom and you do not have twrp installed. TWRP may break OTA updates. At best case an OTA will just replace your twrp with stock recovery. Root also should not affect OTA updates. So no problem getting ota even if bootloader is unlocked as far as I am aware of

[Solved] Sensors not working when using a Custom ROM with a custom vendor image

I have a weird problem:
When using Custom ROM's that use a custom vendor image, all sensors stop working. But when using Custom ROM's that use the stock OOS vendor image, Omni ROM and Paranoid Android, they work. On OOS they obviously work too.
Thing I've tried so far:
MSM Download Tool (Upgrade and SMT Download Mode)
Flash ROM's with fastboot
Flash ROM's with TWRP
Firmwares I've tried so far: 10.3.0 (global), 20.0.3 (eu), 10.0.2 (eu)
I don't know why only I have this bug apparently. I would appreciate everyone's help into investigating into this.
btw here's a log of crdroid (this rom uses a custom vendor image) for those who want to check it out: https://www.dropbox.com/s/3myddc1rzijqbcm/log.txt

Question Flashing Miui.eu

I want to try miui.eu and was wondering if I still need to update to the latest miui. I'm still using miui 12.0.3 global version.

as I had to wait for my bootloader to unlock, I updated my pocox3 to lastest build at that time; 12.5.2 global
then after unlocking, flashed 12.5.2 eu rom, had no issues so far, currently updated to 12.5.5 thru dirty flashing. you have to wait for like 3-5mins for first initial boot of eu rom after flash (if you're waiting more than 10mins, its a bootloop).
having some experience with flashing custom rom on xiaomi devices..... i found out it's always best to be on latest firmware before switching roms, else there might be slight chance you experience failed flashes/bootloop problems, etc... xiaomi itself generally recommends getting to latest global rom, then doing anything *custom*.
