I have a Mi Max 3 global version (M1804E4A) which has simply stopped working on 4G/LTE network. I have been using the same carrier and I have also checked by moving the sim-card to another device where LTE works just fine. I have moved the SIM-card from one slot to the other, tried manually selecting network but only 3G or 2G networks appears on the list. Also did the airplane mode and various types of resetting.
Is my best bet a hardware defect or has Xiaomi bricked the phone with an update?
MIUI version 10.3.3
Kernel 4.4.153-perf+
Reinstall the firmware

i have lg g3 dual d856
its official 5.01
now rooted
stock recovery
sim 1 has option for 4g 3g and 2g
sim 2 slot is for 2g only
i was using sim 1 for 3g and sim 2 for calls
but latter on i got some free 3g data on sim 2
i physically swapped sim slots of sims for using 3g of sim 2
now my sim 2 was in 4g/3g/2g slot of phone
and sim 1 was in 2g slot of phone
upon reboot i was unable to use 3g on sim one
while selecting manually error was shown that sim 2 is in wcdma mode ...
now mannual searching for networks in sim 1 only showing gsm signal
while sim 2 showing 3g networks
restart reboot nothing worked
factory reset solved the issue
but again upon swapping sims phone was stuck in gsm mode on both sim
again factory reset did the job .....
an y one else having this issue ?
Only work around is downgrade to kitkat....

I'm having the same issue. For me factory reset didn't fix it. However, now slot 2 runs 3g/4g while slot 1 is stuck in 2g, so I just put my data sim into the slot marked 2G (which now runs 3G/4G) and my other sim into the slot marked 2G/3G/4G (which now runs only 2G), and that works just fine. The 2G/3G/4G setting for slot 1 does nothing now, and there's no such setting for slot 2, but the latter is running 3G/4G anyway, so I'm ok with that.

which firmware are you on?
one work around is switch both sims to 2g then replace sim and re boot ....
factory reset while both sim are removed
but i think this issue is not present in official 6 update.

Slot 1 is already stuck at "GSM only" and slot 2 doesn't have that setting at all, so not really sure how to do that.
download flash latest firmware LGD856 v20c from here
http://lg-phone-firmware.com/index.php?id_mod=41
back up your data ( all data will be erased )
remove sd card
remove both sims
flash it ( for guide search in forum )
after booting turn on phone use it for while and again factory reset it
now put both sims and it will be normal again i.e sim for 2g 3g and lte and sim 2 for 2g
one bug i have noted in v30b firmware that if we search mobile network in manually it will return error but auto network search will work normally

Is there some reason not to flash version V30C instead? Will I have a problem rooting it?
(Actually I seem to have lost root somehow in my current setup as well, I really need it back..)
Humm
For root i won't recommend it .....

Actually the thread is year old ...&
I have personally changed lg 3 ...
V30b was my last firmware ....
Rooting was not done
Only bug i came across was network manual search was returning error....
And battery drain was insane also ....

I've installed crDroid running android 7.1.1 and now both my sim slots support 4G.
When i bought D855p it came with 4.4, then i updated to 5.1, all official. After this i installed Cyanogenmod 12.1 and everything were fine. But when i installed 6.0(poland) my network signal keeps droping the intire day, it changes to UMTS and HSPA. I cant use my phone as a phone. The only way to solve this is, every time that i turn off the cel or put in airplane mode, is enter in MOBILE NETWORKS > NETWORK OPERATORS > SEARCH NETWORKS and choose GSM. (but i need to do this EEEEEVERY TIME that my cel turns off/airplane mode).
6.0 is the only ROM that i can choose GSM and the signal keep ~stable~. At least i can use my phone as a phone !
I did a backup of my IMEI before installing cm12 as well.
Things that i already tried :
-Flash ALL modem (ALL) , including 21C.
-intall cm13 and after cm12. Using TWRP 2.8 and 3.0.
-stock 4.4 , 5.0 , 5.1 and again 6.0. Using LGFlashTools
-MANY factory resets and wipes !
anybody can help me ? :good:
Same issue. I am on stock 4.4 and mobile network signal keeps dropping on weak signal area. I set to gsm/edge mode to mobile network. But nothing goes fine.

Doesn't work , sadly :crying:
i also tried to put in Network mode : GSM/WCDMA ( worked ) but when i choose GSM/WCDMA/LTE auto , signal drops every time. It is a solution to do this, but i cant use my LTE, and it sucks ...
Disable VOLTE n go to ur models service menu (check google) for me it was
*#546368#*851# (my model = d851)
*#546368#*XXX# (ur model=D8XX) verizon sprint numbers are differently
go to field test >network mode>set GSM permanently (try different gsm 850,990,etc)
Back > RAT selection > select GSM
U cant have network problems now cuz ur permanently set to gsm dont use 3g or 4g use wifi
hit like it helps

I'm sad to hear that. Try also flashing modem 21C. There are also other guides for restoring your signal around the forum, different things seem to work for different people.
Hello
I will try to be simpler as i can
I have a MI MAX Prime (4GB/128)
Everything was ok and working right until MIUI 8.2.3.0 OTA arrived.
After update my phone started to experience Network disconnects and reconnects, "NO SIM Card, NO NETWORK, VIRGIN 4G", This happens at random periods but more often when i wake up phone from idle.
Nobody on Xiaomi Forums helped me, not even developers, Phone carrier told me to change sim card but problem persisted.
3 sympthoms.
1. After upgrading to 8.2.3.0 i can't search for networks manually. (http://attach.en.miui.com/forum/201705/09/033557amdkj2j33bkmyybm.jpg)
2. I use a MVNO which says i must use Roaming even locally, but this NEVER worked even if activated (http://attach.en.miui.com/forum/201705/09/233925hg9b3p55hm3pcpk9.png.thumb.jpg)
(http://attach.en.miui.com/forum/201705/09/233923kydk07ysor4rt0cz.png.thumb.jpg)
3. I noticed this weird pattern while charging (http://i.imgur.com/SPtvuqY.png)
I have done a factory reset and a rom flash via EDL, but problem remains.
I really don't know what to do now
Thanks in advance for your assistance
Well I am on the 8.2.5 Mi Max (not prime) & you can choose network manually by:
Settings - Sim card and mobile networks - tap on the preferred sim card - mobile networks & switch off the chose automatically and select preferred one.
You have to describe beter what is happening with your network connection. Does it gets blocked or disconnects completely (aka ril restarts) also does switch on/of air-plane mode resolves it?

In half a second Network disconnects and reconnects,
first "NO SIM Card"
Then "NO NETWORK"
Then "VIRGIN 4G",
It disconnects and reconnects every time.
Specially when unlocking the phone
Notice there is not airplane mode activated

It works hire.
Try rolling back to older versions, 8.1.9.0 is enlisted on official page.
http://en.miui.com/extra.php?mod=rom/download&r=302&mobile=no#458
Obviously somehow RIL is getting stuck & re-initializing (restarting). Can you direct me to a MiUI forum url where you failed complain/bug report.

Definitely a software one, simply something didn't fit in (either a RIL or related cellular radio libs) good when you updated so you need to revert to previous one with other RIL and libs. Then you can try again with 8.2.3.0...
Flashed to 8.2.1.0 with miflash via EDL mode.
Problem remains... Seriously WtH?

Assuming that your bootloader is unlocked I suggest you flash exactly the version with which the phone came, I flash ever with any issue via adb-fastboot placing decompress rom files in the same folder in c: with option "flash all".

You are doing something wrong. I pointed you out to the 8.1.9.0. For Mi Max Prime Global stable. I don't know where you found 8.2.1.0. at all it's not enlisted on the site not even for a China Stable (that goes up to 8.2.2.0.)...

from the website i can only download

Please wipe all data in Recovery mode if you want to update to a discontinuous ROM version, or downgrade to an older ROM version using MIUI full ROM pack.
I don't have access to recovery mode since i don't have TWRP and my phone is bootloader locked
After downgrading to 8.2.1.0 and rebooting twice the problem has been fixed, it's been 48 hours and there is no more issue
it's really sad that NOBODY at Xiaomi forums/Help desk/ customer support gave a single S#it about it.
If you are going to purchase a Xiaomi phone, think it twice, there is 0 support. Besides XDA.

You should check your IMEI *#06#
If IMEI is missing:
Open the file imei.qcn using hex editor and looking for value:
Code:
08 8A 96 72 01 42 99 81 05 - Sim 1
08 8A 96 72 01 42 99 81 86 - Sim 2

Xiaomi.eu rom
Lineage rom,
both of them have this bug, the only way to have a functional rom is with official global stable 8.2.10

thanks in advance
The Nougat to Oreo OTA update would never install so I did a full wipe and manually installed OCXS27.1 via flashall. since then, I lose all signal/data every 2 minutes or so. If I go into Phone info (*#*#4636#*#*), I notice the Mobile Radio Power toggle will switch off/on intermittently.
when I try resetting all network settings, the connection becomes consistent but the phone doesnt recognize I have mobile data (shows full bars and 4G LTE icon).
I have tried several different basebands and their corresponding OTAs but the issue persists, an issue that was not present on Nougat.
- M8998TMO_20207.117.02.41.01R
- M8998TMO_20207.117.02.41.02R
- M8998TMO_20207.117.02.41.05R
- M8998TMO_20207.117.02.41.06R
I've even tried a different sim card.
any ideas?
When at Phone info, you can change Preferred Network Type to Global (PRL) or LTE/UMTS auto (PRL) if you are outside of US. My ATT (of course carrier unlocked) is now running on LTE/UMTS auto (PRL) and everything is fine.
I just got my Mi Max 3 and want to test it in Germany. I got two sim cards which work in different other smartphones and they don't work in my Mi Max 3.
SW Version: MIUI Global 10.3.2 Stable (10.3.2.0 PEDMIXM
Is this not a official rom? I can't unlock this device because I would need mobile data. Do you have any infos how I could get this working?
I tried:
1) reset device (twice)
2) I pressed sound + and power to delete it another way
When I go into SIM infos it shows that my devices mobile radio is switched off --- I just don't know how to activate it.
Thank you very much
Data is enabled?
Check the apn settings if the correct apn is installed.
