No SIM, No Wifi after global stable update - Xiaomi Mi Mix 2 Questions & Answers

Hi, I bought my device with global stable 8.5 rom with officially unlocked bootloader with replaced imei (Turkey Problems).
Installed miui 9 developer beta without problem (xiaomitool)
Downloaded 9 stable recovery virsion and installed with Setting, system updates, select package...
Device booted but no sim or no wifi network. So I cannot pass mi cloud account validation.
I can flash twrp and all fastboot versions of xiaomi roms.
Xiaomi roms can boot but I can not pass mi cloud step.
RR, mokee roms installed succesfully but they don't boot.
I have QCN file backup but I can not restore it because I can not take phone to diag mode over twrp.
Is this problem related to QCN file, any suggestions ?

same problem here

You could try with a usb type c to ethernet adapter to pass activation.
Strange Problem you ve got

Hey! I wanted to ask if you found a fix for your issue since I am having the same problem now after updating my phone.
Ty

Mokee and RR will probably work if you format phone by typing yes in twrp after installing the zip

Galaxy Note 2 N7100 - No Sim Card

Hi Folks. Can i request some assistance please? I was running Standard 4.4.2 on my device and decided to flash Resurrection Remix for N7100 onto my device. I initially loaded TWRP 2.8.7 and installed RR 5.7.2 with the appropriate "slim" gapps. Once loaded, i got the above error. I loaded TWRP 3.0 and tried again, no joy. I also tried RR 5.7.3 and still no joy. Could someone please assist as i really need to use my device.
Hello Guyz,
I also faced same problem on my note 2 (N7100),
Network issue in all CM based rom (RR, AICP, Vanilla Unicorn, Temseaks and others),
other hand all kitkat rom (Eclipse and Ditto) installed perfectly but some time I faced network problem (In a day faced 3 to 4 times) until I restart the phone.
Anyone here to solve this problem and help us.
Thanks in advance
Best Regards
Phone is running the latest bootloader and modem? Phone displays the correct imei by dialling *#06#?

*#06# just says IMEI - no number etc
Im also having same issue.. Is it due to TWRP..? updated TWRP to 3.0.2 n flashed RR rom 5.7.2 over 5.7.0. Then No sim.. tried to flash back 5.7.0 no hlp, tried eclise v2 after full swipe.. No help so far.. Pls guide, many ppl getting into this prob i think..
Flash back to a stock rom to see if the imei returns. If it does, make sure to backup the efs folder before flashing anything else.
If the imei does not return after flashing a stock rom, you'll have to recreate the efs folder and inject the folder back to the phone.
The lack of an imei could explain the SIM card issue. You may not be able to connect to wifi either.

mine too, after i install cm 12.1.1 when i start the phone there's no sim detected. i really need somebody to fix this problem.
With a sim card error, the first thing I would check is the imei and whether the phone is running the latest bootloader and modem.

Huawei mediapad M2 10.0 A0L1: missing wifi

Hi guys! first of all sorry for the poor english.
I have a Huawei mediapad M2 10.0 A0L1 said M2-A0L1 , 3 Go ram , 16 GB, 3G sim card, EMUI 3.1 android 5.1.1, Build : M2-A01LV100R001C233B011SP01-log.
Custom rom, no root, no bootload
I think it is a chineese modele.
Now the story:
I tried somedays ago to upgrade the mediapad with some huawei updater found on the playstore, as they say at my own risks. I tried to be as carefull as I could (updating/grading mediapad could be tricky as some models herbely differ from one another).
So I found one (mistook) and it perfomed the uppdate directly within the internal sd.
The update seemed to have suceeded but after the reboot nothing seemed to have changed, I even tried a second attemp but still nothing changed. I then wanted to connect to internet but no connection eventhough wifi toogle was on.
I gave a look to the settings and it appears that IP number is missing too.
I recently tried to upgrade via external sd to android 6 (europeen version) but failed once again.
Then performed a factory reset since the recovery reset ( power button + low sound button) did work for me. And even with all that done still no wifi
What should/could I do , that appart the tablet is running clean. I just need my wifi back.
THANKS FOR THE HELP and have a good day

Hi, sorry to hear about your troubles from flashing an incorrect ROM. It may be that the ROM you flashed messed with the radio partitions on the device, or that your /system/phone.prop file is incorrect.
Here is the official Huawei ROM for B025 for the M2-A01L (M2-A01L, Android 5.1.1, EMUI 3.1, V100R001C233B025): http://download-c.huawei.com/download/downloadCenter?downloadId=78087&version=310901&siteCode=cn
You can try downloading and flashing this ROM after performing a factory reset on your phone. Hopefully this will flash the clean ROM onto your phone, fix your radio settings and cure your wifi problem. Good luck!
EDIT: Also, please note that some ROM versions have problems with Wifi if the Wifi router is configured to send out 5GHz "AC-Only" mode Wifi connection - you need to set your wifi router to "Mixed" or "N-only" mode on the 5GHz band to get wifi connectivity back.
Thanks beast.in.black I'll give it a try and let you know whether it works for me!
Cheers
Soooo it worked, wifi is back again thanks to you beast.in.black. Now do you think I can find and download the asian (chineese) marshmallow version ?
Thanks again

As far as I know, there is no Marshmallow that exists for this device (10.1 model)... Where did you find one? There is not a single thread in this forum that says that a Marshmallow ROM exists for this device
Hey sorry for the late answer but you are right there is none it was a mistake.
Have a good day

Weird Issue with MI MAX - Constant Network disconnects. Please help!

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.

Yup it's all Radio Interface Layer (RIL) related.

It's a physical issue? or just rom?

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.)...

But those you mention are only update packages, iirc MIUI said that fastboot flashable roms has to be in tgz format.

Yes i did, but i can only download the latest version from my cellphone 8.2.30 which gives me bugs
from the website i can only download
http://update.miui.com/updates/v1/fullromdownload.php?d=helium_global&b=F&r=global&n=
Xiaomi Mi Max Prime 64G/128G Latest Global Stable Version Fastboot File Download
which is helium_global_images_V8.2.3.0.MBDMIDL_20170420.0000.00_6.0_global_ece8e97134.tgz
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

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

WIFI Not enabling

Hi Guys,
Noticed today that my WIFI won't turn on. You can try, it attempts it - but ultimately, it goes to the off motion again.
I've tried going to the following and backing up the WPA Supplicant file, but still the same. data/misc/wifi/
I'm using the ROM MIUI 9 from Xiaomi.eu v. 7.10.26 - Rooted.
It's worth pointing out WIFI has been running fine on this since I installed it (5-6 weeks ago).
EDIT: Just checked, and the WIFI Mac is 02:00:00:00.00.00 Will look into this, not sure how its happened as I didn't change a thing!
Thanks!
EDIT:
So I restored from To October 15th, wifi works. Go figure... What settings do I need to take from that to the current version? Or just easier to update to a different ROM?
Just to add to this, I done the OTA and that fixed the issue. No idea what caused it...
I just get the same bug with WIFI MAC address 02:00:00:00.00.00

Updating to 7.12.21 did not fix the bug. I had to factory reset the phone to have wifi working.
Good job it's fixed! Interestingly, did your phone battery go in low power saving mode prior to it occurring? I seem to remember that being so. Can't say for certain.
try :

chiron_global_images_V8.5.1.0.NDEMIEF_20170925.0000.00_7.1_global_f58374960a.tgz
global stable 8.5.1.0
or
eu rom 8.5.7.0
I have a wifi issue.
my wifi works excellent on miui 8.
non of the miui 9 roms either stable or beta and official or pro/eu/epic connects internet via wifi.
wifi opens but connected networks stay saved only and after a few minutes my network disapperas.

Mix 2 wifi and IMEI problem
Hello, hello I need your help in a matter. I have 2 devices in my hand. Imei had to be discarded. After installing twrp and magisk, I deleted modemst1 modemst2 fsg partitions from pc while in twrp to remove IMEI from qpst. Whatever happened after that, wifi does not turn on when partitions are deleted match address was 000000. I did not take backup. I open the device with rooted diag but says qpst no phone connected. He sees the port but does not recognize the device. I can't write in Qcn. Fastboot rom, I installed custom rom did not recover. What should we do?

SIM card and Wi-Fi not working at all

My Redmi Note 5 (Global) fails to detect both my SIM card and Wi-Fi hotspots. Not only on MIUI, but also on Havoc and such.
I flashed the official ZIP from miui.com, the fastboot image and even the firmware zip, but the issue still remains
Any idea on how to fix that? Thanks in advance!
