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.

If model is same, then country doesn't matters.
You will only not get the language but sometimes you may miss features from your carrier, like
If Indian user flashes J710FN France, then indian user will not get VoLTE feature from his carrier.
Nice to hear this worked for you

That is still a nougat rom. I think there is slightly newer version still on nougat, but several more with update to oreo.
Either way you can use HWOTA to to do FULL-OTA updates. . Having root is blocking you from taking the ota in a regular way, as of now.
This link should help you out.
https://forum.xda-developers.com/honor-7x/how-to/guide-honor-7x-flash-oreo-update-t3781649

Thanks for your prompt reply.
Should I directly try to upgrade to BND-AL10C675CUSTC675D1B365 (8.0.0.365) from Android 7?
I have copied the 3 update files as per the instructions in thread.
I tried flashing TWRP available in HWOTA7 using Huawei MT Tool, but strange folder names are coming in TWRP (Crypted?), pls help me.
Also, can u PM me your whatsapp/ Telegram/ e-mail id, so that I can quickly contact you in case of any issues while upgrading.
Thx!!

That is normal to have the strange file names.
Afaik , you can flash direct to that version, as long as it is always the fullota.

Since strange folder names are coming, how do I locate and install the 2.6GB file?

Wifi and SIM not working. Unlocking impossible.

Hello
my Mi Mix 2 suddenly couldn't read my SIM Cards anymore and I even can't turn on wifi (turns itself off immediately). Both functions broke at the same time.
As nothing helped, I have done a factory reset. Now im stuck in the language selection screen, where I need to unlock the phone with my Mi Account first, which isn't possible because there is still no way to establish an internet connection.
My bootloader is locked and my last hope was unlocking it and flashing another/Stock ROM. But the unlocking Process with Mi Unlock always fails. (Can't get info, connect again at 50%; on my other PC it stops at 99%)
Can someone help me? I'm so lost.

No I'm on vacation right now and don't have my mix 2 with me.
I'll keep you updated as soon as I can in about 2 weeks. :good:

Hi all, did you find any solution to get wifi working?

No I still can't do anything with the phone. Bought a new one by now.
And I don't trust this indian guy above with his instagram account and only one post on xda. Seems like a scam. If he has a solution, why shouldn't he share his information with us publicly?
Tried contacting xiaomi mail support, but the support is a ****show.

Well, where were you all, dear ones, I missed you for a year. I killed persist in August, but somehow I restored imei using Android 7. What the phone didn’t give out - but as an option it always worked with custom Android 9 wi-fi. Than just did not sew. In short, I bought mi 9, and tied it to the same battery. Mi mix 2 I blocked and gave up. But somehow everything decided to heat it over a gas stove and make a testpoint. On mi9 sat mi-room and did not think)). But somehow I decided to do mimix2 again and configure m: rolleyes: i box s in parallel. As a result - mi 9 is locked, it doesn’t see SIM cards, but there is wifi)) Mix is ​​not even sewn even through testpoint, I have been listening to music on mi box for a month now and am writing with Chinese, Indians (sorry if I hit anyone). I’m even thinking, maybe the iPhone and to hell with these firmware, I’d better get married a second time. I got sick already, more electricity was spent on the firmware than these devices cost. (If you don’t understand anything, beat the Google translator - I’m just blowing it, I’m too lazy to write in any non-Russian languages): laugh :: la ...

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

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

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!
