My Mi Max does not have option for LTE after flashing latest global developer

HI,
I bought my Mi Max 32GB in Indonesia and it came preinstalled with unofficial distributor ROM. It can't do OTA updates, so I flashed to latest MIUI Global Developer using MiFlash Beta through adb edl mode. My bootloader is still locked. The flashing process went successfully and I'm using the device without any problem.
Then I realized that my phone does not have LTE/4G option, I already try everyting on the internet but no result, including:
Set locale to Singapore / Malaysia
Dialing *#*#4636#*#*
Factory reset
Reflash

Flash your max with china stable/dev ROM, wish some lucky there...

yes..
i confirm that LTE will be enabled in both dev and stable china rom
or,,
try the custom rom: RR or CM13
regards

Maybe u can use this trick which need u to add a little modification to your device buildpromt. I already try it before and it works on my mi max.
Actually there is a link that can guide you how to do it but i'm sorry that i can't tell you rightnow coz i forgot about it. I'll do some search for a while and will inform you later when i find it again..
Ps: sorry about the grammar coz am not that fluent enough on english and am a newb in this forum
*update:
Am sorry about the late update and about the guide, am sorry again that i can't give you the link bcoz of the forum rules.
Based from the web, what i can tell you is this :
Firstly,, DWYOR!! am not responsible for bricking your device!!
must have root on device
have root xplorer or buildprop editor or any other like it installed
now use root xplorer navigate it to /root/system then find build.prop
open build.prop with HTML editor or text editor
find text ro.product.device=hydrogen then add # in front of it like this #ro.product.device=hydrogen
save it and reboot
now go to the network setting u can see LTE prefered is there
notes:
this trick can only be applied to MIUI 8 global dev rom (idk if this can also be applied to miui 8 chinese dev vers rom and there is a different edited thing for miui 7)
hydrogen is another name for 3/32 MiMax so for another xiaomi phones it will be different ex. mi4c=libra, RN3 Mediatek=hennessy etc
this trick can be applied to any xiaomi devices(sez the web not me) that already support LTE
lastly,, DON'T FORGET TO ALWAYS BACK UP b4 you do all of this!! in case something goes wrong.
i already tried this and it works on my MiMax running on 6.8.11 global dev rom and now on 6.8.25 global dev rom it also work.

You must install the firmware from the mirror version (The mirror and the tablet like version have exactly the same internals) so the hardware is the same CM84, therein a 1.90 beta version that would work great, it has some better quality of life enhancements! on that thread I asked in Russian if I can flash that mirror firmware on my tablet like device, I flashed it and everything was ok! In case anyone is searching info, here is the thread from 4pda:
https://4pda.ru/forum/index.php?showtopic=792739
If you manage to make an account (there are tutorials on web how to solve 4pda Russian captcha to register) you will se a download link from a custom rom named CATS IV you can safely flash.

Hi Hardy, mind to share with me the firmware you used to flash your device? i bought this car cam from china and it does not come with google playstore and cannot install apk apps... hope you can assist me for the firmware. Thanks in advance.

Here do you have the download link from the latest CM84 firmware:
https://disk.yandex.ru/d/qhbWzQD43Q94GN

hey got a similar DVR android mirror. Was wondering if you could send CATs IV firmware? I don't see it on that website?

Hi, i have the same device, my son played with it and locked it by pin. Can't find a way to factory reset it.
If i enter recovery mode i get a android photo and can't go further.
Any help to reset the device?

I recovery mode I can't pass the image with broken android.

Question Yet Another Bricked Mi Pad 5 after Global Rom

sigh, yes I am embarrased at what I did but I have bricked my Mi Pad 5 and need a hand. Background:
- new Mi Pad 5 China hardware but with Global ROM flashed by the vendor I bought from
- the Mi Pad started up fine and I logged into my google and Mi accounts with no issues
- noticed the bootloader was unlocked and that google play said device is not certified
- I used fastboot OEM LOCK *very stooooopid* and the device rebooted
- on start up is says "This miui version can't be installed on this device" and now it's bricked
- tried to wipe data but no luck same error
- tried miunlock tool but it tells me I have to bind my id to the device :-(
- tried XiaoMiTool V2 but it is also stuck
- tried Mi pc suite but it will not detect the mi pad
Is there way way to simply recovery back to the latest chinese version of the rom - feels like I am stuck between a rock and a hardplace :-(
Thx in advance for your help, FredT

Download an China fastboot rom from https://forum.xda-developers.com/t/miui-updates-tracker-xiaomi-pad-5-nabu.4328591/
Unpack and use the included installer

thx for the advice, I tried it but anything I do with the included installer tells me it can't work on on a locked device.
still looking for a solution....

You can not unlock again?
oem unlock command

yes unfortunately my stupid error was that I did an OEM LOCK thinking that would be ok and to fix the playstore uncertified issue :-(
when I try to unlock it tells me that I need to bind my ID :-(

Unlock again, install stock china rom, factory reset and lock bootloader

yeah when I try to unlock it now it says that I have to bind my MI id again but I can't boot MIUI to do that - so really stuck as it won't let me unlock

when I try oem unlock I get:
C:\Users\fredp\Downloads\miflash_unlock-en-5.5.224.24>.\fastboot.exe oem unlock
...
FAILED (remote: Token Verify Failed, Reboot the device
)
finished. total time: 0.014s

How did you unlock it in the first place? Maybe use the same method? Mine (pro 5g) came with CN ROM with the bootloader locked, so I had to go through the usual procedure of binding my Mi account and waiting for 7 days to unlock the bootloader. I used Mi Unlock as Xiaomi suggests.

Mine came from the seller with the global rom installed even on the CN hardware so they went through that process which in retrospective was not such a great idea, my mistake was that I did not bind my ID to the device before trying to lock it.

I don't know if you solved your problem, but when this kind of things happened with Xiaomi phones, you needed someone with an authorized Xiaomi account that could log in Xiaomi flasher and unlock your device for you. I remember seeing a guy from Russia who did this procedure for many people over the k20 pro fórum (he charges 20us I think)
Sorry for the kind of generic information but it's been sometime I saw this and can't quite remember the details. Try to search for more info about that in k20 pro fórum.
What I can tell you is that if you find the right person to do it for you it's quite easy and fast. I think he does it over TeamViewer.
Anyway, don't give up. It is totally recoverable

Here bro, this group in telegram can help you
A guy there has an authorized account
Search for {Mod edit}

How was this fixed? I also have the same problem(locking the bootloader after flashing and bricking it).

I tried to reachout to {Mod edit} and already paid for the service fee, and I am feeling that this is a SCAM, i have been waiting for a day and still no progress with this. Im confused if this is really a thing for our bricked units. Hope they were just really busy and not a scam.
{Mod edit: Telegram screenshots removed}

Update on my transaction with {Mod edit}, it is legit! Cant beleive they revived my mi pad 5. This thread is a big help. Thanks!

I understand the reason...
But how can we suggest a solution to people with bricked device if this is the only option available?

Help me to change blackshark 3s cn rom to global rom

Hi everyone member here.
I'm a black shack 3s user, I bought this device from my friend last month with china ROM installed.
I have questions, Where and how do I get and change from china ROM to global ROM?Because I have a problem with the china ROM on my cellphone, like one of them there is no notification from the whatsapp application so I have to open the application first then there is a message, and the next problem can't open email with gmail app.
But beyond that, my cellphone doesn't get updates and stops on JoyUI 12 20.08.08.
Do you guys have a solution ?
