Problem sim card / Bluetooth and wi-fi - Not active - Xiaomi Mi 8 Questions & Answers

Dear friends,
I had a problem with my xiaomi mi 8, it fell to the ground and the car passed over it, I thought at first that it would only be the exchange of the screen and when trying to take the battery, also damaged.
After buying the display and the battery and installing, I had a surprise, my simcard does not detect, my bluetooth and wifi do not activate, mac adress is only 02: 00: 00: 00, I've read some reports of people with the same problem .
I wonder if the problem might be software or hardware?
Was it because of the battery change and display or will it be that with the problem occurred the car having passed over damaged some plate?
I have tried some persist.img procedures and install custom rom and others ...
Can someone help me in anything ??
Appreciate.

Hello friends,
I tried several procedures on the internet until I screwed up my IMEI ...
Could someone help me re-write the IMEI, do not want to change, just write the original IMEI of the box ...
Worse I did not back up anything ...
I've been reading about EFS file
Anybody help, please?

Please, can anyone help me??
I've tried all the procedures and nothing ..
I have the imei information in the device box.
I am without network signal and wifi, I am without using the cell phone.
Do I need some kind of .qcn file or an efs backup?
Please help me friends

[Help needed] Emergency calls only

Hi there!
I've looked around the forum for a solution to this issue and unfortunately my case doesn't apply to any of the posts I've found.
Three months ago I followed the instructions of the hex hack posted here: http://forum.xda-developers.com/showthread.php?t=881162 in order to restore my phone's IMEI (since then I've been using the generic one 00499... etc)
The phone was rooted using Odin3 v1.7 to install the CF Root Kernel CF-Root-XX_OXA_JVK-v3.1-CWM3RFS.tar and finally I unlocked it.
The thing is my phone can't make/receive any calls. I've tried my old SIM card in another phone and it worked.
It's not the SIM card. I even asked for a new one just in case and my phone company sent it for free, but it's still not working.
I tried a different SIM card from the same company in my phone and it works just fine, so it can't be the IMEI being barred.
The weirdest thing of all is I still receive emails and whatsapp messages because the phone logs in to the 3G network without any trouble. Under "Status" you'll see:
Phone number - Unknown
Network - Claro AR
Service state - Out of service
Mobile network state - Connected
I restored the nv_data files in the efs folder thinking they might have been corrupted but I couldn't solve anything.
WTF is going on? Any expert suggestions will be much appreciated.
Thank you!
claro ar
Did this happens suddenly 3 o 4 days ago?

Please post your solution if you find one.
thanks

Yes it did. Not sure when exactly but must have been on wednesday night.
I haven't found a solution yet but the phone is working since this morning. I don't know for how long it will stay this way.
Please post any news or changes in your phone. It might help us, you never know.
Thanks
Hi,
I'm having the same issue all over again, exactly as described above.
Can somebody give me a hand here? Please?
Thank you very much!

[Q] No network issue LG Optimus 4x HD

Hi guys,
I have a LG Optimus 4x HD with stock rom (Jelly bean). About three weeks ago, I suddenly lost my network connection and it looked like my phone didn't recognize my SIM card. I put my battery and my Sim out and in my phone, but that didn't help. I tried many SIM cards and they work excellent on my other phone. When I turn my device on It just boots up and doesn't ask for my pin code at all. I see no difference when my SIM card is in or out my device. However, it does recognize my SD card, so I think there is a problem with the software? On the lock screen I just see the message ''no service'' and at the top I see this (first pic). When I try to dial someone it says ''reorganization of internal processes. Try it later.''. I read on a forum that I had to go to ''mobile networks'' in settings, but that isn't possible (pic 2).I also tried to put some paper between my sim card and my sim card slot but that didn't work either. Does someone have this problem too or is there somebody who can help me to solve this problem? Your help would be greatly appreciated.

I discovered that my phone doesn't have an IMEI and IMEI SV code anymore. It also doesn't have an baseband version. Do you guys know this caused the lost of my network connection and does anyone know how I can recover my IMEI number? Finally I managed to enter the mobile networks in settings by do a long tap on the data icon in the notification center. I hope someone can help me.
I have the same problem as you. With every restart the phone is unable to read the sim card. Also the baseband is shown as unknown, and I don't have imei no. The solution for me is to remove the battery, and put the phone in the refrigerator for 10 minutes.(yes in the refrigerator The phone is getting very hot when is searching for network and to have it really cool helps apparently. Try it yourself to see if it does the job for you and let us know.

Thanks for your reply! This morning, my phone finally asked for the first time for the sim password and I finally got a signal. I got my IMEI and my baseband number back. Unfortunately, after an hour or so I tried to send a sms and I wasn't able to send it. I got the error no USIM or so. The IMEI and Baseband number disappeared agian. I turned flightmode on and of and I didn't get a signal again... New today was that I am now unable to connect to multiple wifi networks too. Now my WI-FI MAC-adress is 00:00:00:00:00:00. I already lost the phone and I now also lost the smart part of my smartphone... I also tried to put my phone in the refrigerator but sadly it didn't help. I think I have to buy a new phone....

Sorry to say that "It's time to say goodbye"
I got same problem with you and try all kind of possibility. Here is final verdicts:
- Some phone repairers I know said It's the encrypted baseband partition is damaged, unless you have backup of that, it's a no-go
- I've tried to reflash the phone and it will stuck at 10%, you have to push really hard at some point at the back to make is flashable. After that, the signal back on with baseband and IMEI.... but only for a few restarts it will be gone
Hi blbterminator,
I already said goodbye to my p880 (has been replaced for the G3), but thanks for your reply. Now it's clear for me that's it's a hardware issue.
Maybe do you know if this problem only affects the lg p880 or other brands or models too?
Many thanks!

help me please!!!!!! galaxy note 5 signal problems.

Hello. First of all, I searched the threads before posting to no avail. So if I'm being repetitive I apologize. But here's the problem. I have a t mobile galaxy note 5. Unlocked. It's rooted. Running an arter97 kernel, and Jovys Darkstalker kernel mod. Everything is running smoothly and has been for months. Recently the only problem is my signal. 90% of the time it is saying searching. When I make a call it says not registered on a network. This is strange because I have done nothing to cause this change. No new roms, mods, updates, nothing and it's been working fine all this time. I know it is not location related because it was working 100% fine from day one until now. I tried *#06# to see if my imei was null, it is not.
I let the phone search, and then choose an operator, that works temporarily giving me signal, but eventually goes back to, and stays searching. I tried to pull up the service menu using *#*#4636#*#* to reset the radio, but that number is not pulling up the menu. I was told I may have a bad efs, but I never created a backup because until now I never had this problem and didn't know efs existed . I don't know what my next step should be. Any help would be greatly appreciated!!!!!!
Sn: if there is already a solution to this problem on this forum send me a link please!
Try using the Shortcut Master (Lite) to pull up the service menu.
I've also got same issue.
My phone is n920c. I've spent all day trying fix this issue by new rom, but I didn't find solution yet.
Kind Regards,
Marcin

Where did you buy your phone? Why don't you check to see if it's blacklisted first (maybe it took a little while to get listed). Never ceases to amaze me the number of people selling stolen/balance owing phones, or the number of people buying them, for that matter:
http://www.t-mobile.com/VERIFYIMEI.ASPX
Very true. I think i may have solved the problem though. My phone was bought outright through tmobile. I try not to by second hand phones for that exact reason.
I think i have may have found my the solution. For me it was a sim card related issue. Apparently my sim card was exhausted, or had expired. This is why my phone kept dropping me from the network and i had to keep reconnecting. Accordind to t mobile your sim expires 90 days of no use. This dodnt apply to me but whatever. Got a new sim, transfered the number, problem solved. Also something else that greatly boosetd my service. Take the case off. This was why i got the searching status in low service areas and only 2 bars of service in good reception areas. Crazy that in 2015 cases still affect service but it did greatly. So yea my fix was a new sim and take the case off. Very elementary. But i can say it was not root, kernel related thank god :good:

Won't stay registered on network

My S5 Mini SM-G800F won't stay registered on a network, it registers initially but after a few seconds drops to 'Emergency calls only' with the notification that the selected network is unavailable. The signal strength is fine and the sim works in other phones. It's an unlocked phone, using a different network sim produces the same result. Bought it secondhand just over a month ago and it's been fine up to to a couple of days ago, done a hard factory reset but the issue remains.
Ideas for a fix?
This may or not be similar to an ongoing issue I have with my S5 Mini - See below :- Has your IMEI changed to the below at all - 350695200123951-01 ?
"Hi All,
Did any one actually get a fix for this issue as I have exactly the same problem, my SM-G800F IMEI now also shows as - IMEI 350695200123951-01 which is for a blacklisted NOKIA 6310. If anyone can supply an absolute beginners guide for me as to how I can get my original Imei back that would be fantastic.
I am just a user of an android phone and have zilch experience of tinkering with them.
I have seen reference to things like Odin and flashing firmware and am quite happy to give it a go myself and learn
I will post this on a few other threads that list the same issue as I am desperate to get this fixed now as is a waste of a perfectly good phone !! "

No change to my IMEI, consensus seems to be that it's probably a faulty SIM card reader.

Lost signal . Can't connect to network

Hi,
On the way back from work, my phone lost signal. Reset didn't help, I try to install new firmware but didn't help. Only emergency calls I can make,
SIM card works normal on different phone. In side settings, I see my carrier name.
Maybe someone had the same issue ?
Hello there!
I too have same issue from few months. Did you find a solution for this? Everything else works. Looks like some issue with antenna
