Question Global/Indian Rom vs EU rom - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

I have recerived my Poco F3 and it has the RKHEUXM which does not support call recodrding and I am wondering if I flash the Indian rom which I heard support call recording, will this feature be there?
Is there a way to roll back to older version which supported call recording? like Mate 20 if u rolled back to 10 and install the app/activate it and it will work after futer updates.

yeah yeah theres no problem with rollback you just need to edit fastboot command line on batch file to avoid anti rollback protection

Call problems

I ordered my Mi Max 3 from TradingShenzhen and chose the option to have them install the xiaomi.eu ROM. It arrived with TWRP installed, an unlocked bootloader, and xiaomi.eu MIUI 10 v. 8.7.26 installed. I downloaded the most recent xiaomi.eu MIUI 10 ROM (v. 8.8.23) and flashed it in TWRP.
Everything on the phone is working fine except for a persistent problem with calls. Within about 40 seconds of being in a phone call (whether on the phone or through the car's bluetooth) the party on the other side complains that my voice has suddenly changed to being very "tinny" and "robotic" and that they can't understand me. I hear them fine. At all times my signal strength is excellent. Depending on where in the city I am I may be on LTE or LTE+ with four or five bars but the problem persists.
Does this sound like a firmware issue or did I get a bad phone?

Try this fix from @ice0901: Hey I fixed it. Found a post on a thread that will enable VoLTE on Xiaomi Phones. Apparently they disabled VoLTE starting with MiUi 9 due to lack of certifications in certain countries, the US being one of them. To activate it dial *#*#86583#*#*
Thank you for your note. I used the secret code and activated VoLTE, but the problem persists. I called my telecom this morning and a few seconds into the call with tech support the chap said: "your voice has become distorted - I can't hear you" and then he hung up! I was thinking about using fastboot to flash the China Stable and then reflash the xiaomi.eu to see if that clears up the problem, but I am concerned about the announcement that beginning with MIUI 10 v. 8.8.23 "anti-rollback" has been activated on the Mi Max 3 and that you will brick your device if you attempt to downgrade. I also read on the xiaomi.eu forums that xiaomi.eu "disables" the anti-rollback features of the China development ROMs they use. Any thoughts on how to proceed?

Happy to help! Sorry you're going through so much headache. I would suggest starting over as you mentioned and doing the following from @omer1919's instructions from his nitrogen rom thread:
"I suggest to start clean again by flashing 8.8.9 fastboot and then follow the full installation instructions on op post
Installation Instructions:
- Make sure your bootloader is unlocked!
- Boot to fastboot mode
- Format your data to make sure that the installation will be clear using the command: fastboot format userdata
- Flash TWRP Recovery
- Boot to TWRP recovery
- Mount all the possible partitions
- Wipe your data,cache,Internal storage,dalvik DONT WIPE SYSTEM OR YOU WILL BRICK YOUR DEVICE
- Using MTP or OTG copy the xiaomi.eu rom to your device
- Flash the Xiaomi.eu rom
- Wipe cache and dalvik
- Reboot"
Can you tell us what carrier you are using? I also bout from trading Shenzen with the xiaomi.eu rom installed and had call problems at first. First thing I did was follow the advice from this thread. Flash the chinese fastboot then flash the latest xiaomi.eu rom. Then I enable voLTE by typing *#*#86583#*#* into the browser and now my calls work great!
My carrier is Telus (Canada). I followed the advice in the thread you linked (flashed China stable, re-flashed TWRP, etc.) then flashed xiaomi.eu 8.8.23 and this time my call problems were even worse. When I went to dial anyone the phone app would simply say (failed to connect). So I then flashed xiaomi.eu 8.8.9 which other Mi Max 3 users have commented is trouble free, and so far I've been making calls for the past hour to different landlines and mobiles and no call problems. Perhaps there is a problem with 8.8.23, but it is odd that more people haven't had my problems using that version.
UPDATE:
I have now had several messages from other Mi Max 3 users that 8.8.23 caused serious call issues and that reverting to 8.8.9 fixed all their problems. I have now had two days trouble free after reverting to 8.8.9 so I will wait for other reports before considering today's release of 8.8.30 (if it isn't broken why fix it). Besides, MIUI 10 beta testing is now complete for several devices so Xiaomi has begun releasing China Stable MIUI 10 ROMs as of today. I downloaded and flashed the China Stable MIUI ROM for my Mi MIX today and it is working great (despite the odd annoying menu in Chinese). Can't wait for the developers at xiaomi.eu to release their version of the China Stable MIUI 10 ROMs. If the Mi MIX (an older device) has a China Stable MIUI 10 ROM it can't be long before our Mi Max 3s get the stable version as well.
For those of you with call problems using xiaomi.eu MIUI 10 v. 8.8.23 finally an explanation from xiaomi.eu as to the cause. Xiaomi.eu has always 'stripped' the anti-rollback feature from China developer ROMs that they translate into European languages. For the Mi Max 3, 8.8.23 was the first China ROM issued with arb, so in their release xiaomi.eu stripped this feature from the firmware of the ROM. After so many complaints they realized that beginning with 8.8.23 a new modem (required for calls) was imbedded with the anti-rollback feature of that ROM, and by stripping the arb from the firmware you wound up with a ROM that included a modem that didn't work. So on this week's release, 8.8.30, they have left the anti-rollback feature in place, thus allowing the new modem in the firmware to permit normal calls. So you basically have two choices if you stay with xiaomi.eu on this phone - stay on 8.8.9 which is stable and has no anti-rollback protection, or upgrade to 8.8.30 but thereafter brick your phone if you attempt to re-flash an older version.
...then someone try 8.8.30 ? Resolved call problem ?
Can I reverse my actual rom 8.8.23 to 8.8.9 ?
Total disappointed about mi max 3.Bought from mi global store with global rom.When receive it, the calls don't work.I was hijacked to use custom buggy software for flashing rooting and other ****s to do, if i want to use max 3 normally, because there is no official global rom.Never again xiaomi, never.......

First: mi global store is not official Xiaomi store, just a chinese guy, which sell Xiaomi devices from China.
Second: they unlock bootloader unofficial, which is a big problem.
In other words, you got a chinese Mi Max 3, with unofficial unlock bootloader and fake ROM. Buy official global version and anything works perfect out of box.
Plz how can I get official global ROM for my mi max 3. I am in Nigeria and bought the unlocked global version of the phone last two months, August. I need Ur help, pls

Indian rom on global version device.

Could please someone let me know if I can install Indian rom on global version phone, and please share the way to install.
Yes, You can Install it.
The Process are
- Unlock Bootloader using Mi Unlock Tool.
- Download Fastboot Rom of Indian Version.
- Download MiFlash Tool and while flashing, Don't Select "Clean all and lock" option. Just select only "Clean all" option to avoid brick issue.
*Note: Unlocking Bootloader will erase user data. If device got brick, only option to fix it is to take it to service center.
I'm gonna do this tonight, been waiting 7 days to unlock bootloader, just for this.
The only reason I'm doing this is to get stock MIUI Dialer and messaging app, with default call recording built-in.
Can someone confirm this?

No NFC hardware in device itself. So, No NFC in Indian Rom.

Alexa does work but make sure to turn off Alexa hands-free in the notification toggle. My device couldn't play audio, auto-brightness didn't work and videos were sped up. After turning it off everything worked again.
NFC is nowhere available, not as a toggle and not in the settings.

Actually way more boring than I thought. Flashed the China Rom after that and that also sucked. I'm now back on EEA
Can you also tell how to install the Android 10 rom on Indian device? I've been waiting for so long but the Indian Rom is still stuck on 11.0.4

If your bootloader is unlocked and you flash the whole Rom using fastboot, it should not be a problem.
I've read about some anti-rollback 'feature' on some roms, but that would be from Android 10 I think.
Both the versions you mentioned being Android 9 they should not have it.
PS: If you flash IN Rom you are going to loose NFC.
Having the preloader and lk already installed as the megathread intrudes, just need to follow the same steps indicated here?
Do I need to reinstall it after the flash of the Indian version?
Thanks.

no it doesn't only global devices rom get nfc hardware so is software support , conclusion is any device sold officially outside india is global rom and have nfc , i tried indian rom but problem is to make something like that you need to make a custom rom with these features which is nearly impossible because mediatek doesn't care about its' customers and its' restrictions are beyond insane , that's why xiaomi.eu ended support for mediatek phones because of bad platform and crazy restrictions that blocks developers from having freedom that they get on snapdragon platform , it's not xiaomi's fault.

Will System Apps Updater revert ROM?

I have RN8P Global and have flashed Indonesia ROM, Android 10 MIUI 12, in order to get call recording. If/when there is MIUI update and I use System Apps Updater, will phone revert to standard Global ROM (and lose call recording) or will it update to new MIUI with Indonesia ROM?

Question Help with Mi 11X bought in India

Hi All,
New to the forum. A Hi to everyone.
I have bought an Mi 11X in India in very first sale and after setting it up realised it doesn't have Miui dialer and messaging app and instead has Google Dialer and messaging app. Google dialer doesn't save call records beyond 30 days and also doesn't have native call recording option without warning about call getting recorded and I am unable to move messages from my previous Redmi 8 device to this device bcoz of no Miui Messaging app in Mi 11x.
Can someone please suggest how to get Miui Dialer and messaging on my Indian Mi 11x handset. And also let me know how do I unlock bootloader as Miui global forum is blocked in India foe access. Cant access the forum and hence cant place request for bootloader unlock. Please help me. Thanking in advance.
you can record call with Google Dialer or Google Contacts whatever you call that app there's a Magisk module for it just get rooted via Magisk

Its not just about call recording facility. Miui Dialer is more feature rich than google dialer. Like unlimited call history vs 30 days call history. Messaging app is also very user friendly of Miui. I just want a way to get Miui Dialer n Messaging app on my Mi 11x. Either by some apk install or via some other ROM flashing.
im not sure if this helps but maybe you could try installing them from apk mirror, hope the apps work tho.

Solution is to move to XIAOMI EU ROM. Weekly and stable both have MI dialer installed.

You get OTA for both EU rom, weekly and stable, but because a working recovery to handle that is not yet available we still have to do it manualy via fastboot.
Accept it for some time or stand by.

Everything is automatic once you first installed EU rom.
Bootloader stays unlocked until you relock it with MIFLASH rom.
Your data are going to be erased by force because you need to format data at first install and only here. Make them backed up.
I have successfully unlocked my device and have downloaded Miui 12.5 HMK40 ROM from xiaomi.eu forum and setup phone in fastboot mode and extracted the fastboot miui 12.5 ROM and ran the file "windows_fastboot_first_install_with_data-format".

I closed the command prompt window by clicking "X" on top right corner and again started the process by running the file "windows_fastboot_first_install_with_data-format" and now I am stuck at "sending sparse super 1/7" which earlier took only 50 seconds and now taking ages.
Faced errors multiple times but after trying to flash three to four times and changing USB port, I was successful in installing the ROM. Thank you to the community for help and for encouraging to try installing the ROM.
My last genuine query, sorry if I have been too curious about things. I have successfully installed EU ROM. Now
1) Can I lock the bootloader again and whenever there is an update just flash it without the need to unlock bootloader again??
2) Say a Recover ROM gets released in near future, do I have to again flash it a New?? I mean complete format? Or can I just upgrade to it without loosing data and without full format??

You have better to boot latest TWRP and install EU zip with it.
Just check the digest file in the rom zip if it take care not to reject aliothin (your phone).
That's what I did on F3 .
Great rom for my today use.
EDIT: You can NOT lock your bootloader under EU rom, you need to flash an official fastboot rom via MIFLASH.
Take care to flash the same region rom as your phone was first.
But, Stay unlocked that's better if you can.

U can lock ur bootloader only if u have the original ROM region the phone was build for (EEA, MI, IN, ID etc). So, never lock bootloader if u had Indian stock ROM and u flashed EEA or other region build.....most probably ur phone will get hard bricked. Also, never lock bottloader if u flashed any custom ROM (xiaomi.eu, CrDroid, Arrow etc)....not sure if this is even possible, but still

oneplus oxygenos 12 dialer

hello, i upgraded my oneplus 7t to os12 (h1900_11_f17) and root with magisk. How to reinstall the dialer with recording function?
I believe OOS 12 switched to Google dialer, I don't think you can go back to or install the 1+ dialer with built in recorder
this would be your best option - https://github.com/chenxiaolong/BCR
I have call record option in diler... on OOS 12.1
I use India Rom on my Eu/Global 7t...
I just thinking to flash EU firmware, but if you don't have Rec option, I will stick India firmware for now... It's working fine in my phone, and I live end use it in Europe
P.S. I also have tasker shell command for Call Recording (from OOS 11 days... on EU firmware)
su
settings put global op_voice_recording_supported_by_mcc 1
(Run as root)
