Okay, so I recently bought a Nubia z7 max, and it came fine working, sim card worked in lte, all the bells and whistles, the version was a multilang version of the 1.64 official software, so i used the official update tool provided by to update to a 5.0 android version of their software so it would repartition my internal memory in a way that CM12 would work, it worked. All was fine and dandy until I saw a friends Nexus 5 able to dual boot(using MultiRom app from play-store) i was so jealous of him that i copied his build.prop to my phone in an attempt to make my phone think it was a nexus 5. My idiotic attempt got my phone in a boot-loop, this resulted in me flashing a 3.09 version of the nubia software on it then TWRP and finally restoring from my CM12 backup using TWRP. But i have a problem neither sim slots seem to work, i already checked and the sim card works(by putting it into another phone), and no sim works on mine. I would really appreciate it if someone could help me recover my precious phone. Thank you in advance.
Hi, thank you for using XDA Assist. Yeah, never flash or copy system files from a different device than you have. You most likely need to flash the stock firmware on your device and start over to get the sim to work again. The best place to ask how to do this is in your device specific forum.

Hello people,
I've got a problem:
I've bought a Newman N2. Unfortunately I've updated the stock rom - and now I've got no more detection of my Sim card.
It has Firmware Newman_N2_00.22 - IMEI is also correct.
My Sim card works in another handy correct.
I don't know what to do - I've searched already here, but it didn't help me what I found.
Could it be something with the EFS Filesystem? Can I restore it somehow whitouth flashing?
I can't install the CWM. Didn't work for me. The fastboot doesn't work for some reason
Thanks in advance for your help!
There was an info on the newman forums about you must flash the phone without sim.
What if you try it with wipe before flash, and reflash then?
Didn't read that unfortunately... What can I do now?
Try to install the 00.20 FW, but wipe data, and wipe cache before it. And ofc without the SIM.
After it you can isntall the 00.22 FW. It is the latest.
00.20 http://pan.baidu.com/share/link?shareid=188071&uk=1143976775
00.22 http://pan.baidu.com/share/link?shareid=190980&uk=1143976775
Any luck? I found something. To go back to the stock FW you need to flash it via Windows.
"Warning: People who have the first Version of the Firmware ( Date 2012.12.13 ), they should first update to second version ( Date 2012.12.15 ) and then they can update to the last version ( Date 2013.01.12). Because you can get some problems with SIM."
Unfortunately only 32bit drivers included.

I read this too, was because of me this topic
I sent it to a friend, who will flash it with his box.
Finally flashed it to the basic firmware.
Also tried several other firmwares, resetting IMEI - also different sim cards.
We guess the SIM Slot should be broken. Does anybody know if we can order just the SIM Module Slot? Or it would be just the whole mainboard?

See IMEI sim card phone is not registering. Imeili clone phones updated when the network is losing record. I think they do the installation again with Box
Hello, i recently thought about flashing a rom on my phone, i did all the basic stuff unlock boot loader, root etc but when i put the file on my device i got stuck in a bootloop, so i panicked a little and went on to google to find a STOCK ROM for the moto g. I found one and flashed that instead, it did infact save my device and i was so happy at the point, but then i noticed that at the top on my task bar it said i had no signal on BOTH Sdcards when infact this phone only has 1!? (my o2 simcard was in at the time) Anyway i went into setting and it had above he wifi setting "Dual SIM settings" which i have never even seen before. Anyway i clikced on that and it says 'SIM1 Disabled' and below it says 'SIM2 Disabled' Also my Mobile DATA has vanished to. All this worked before i went and screwed up my device. Im kind of in a panic and really dont want to loose this phone :crying: :crying: Please can anyone help get me back my signal and data, other then that everything else is working normal.
Screenshots Attached.

You have flashed a single sim variant of the stock ROM on your device, find the dual sim version for your phone here: http://sbf.droid-developers.org/phone.php?device=14
Also, of course your data has gone as your phone has undergone a reset and firmware flash
All of them are not for 4.4.4 or does that not matter?

Absolutely. From experience, you must flash the dual sim variant. Unfortunately, there is 4.4.4 available, but only for the States. You might PM me the OTA update package and I'll be able to help.
Sent from my XT1022 using XDA Premium 4 mobile app
Cant find it?
Cant find any for O2 uk or retail UK or duel sim or even 4.4.4

Hi.
I have a Xiaomi Mi2S that doesn't connect to any cell networks.
I'm using CyanogenMod 11 nightlies, and after an update the phone lost its IMEI number. I had taken a backup of the NVRAM using EFS Professional, but when I looked for it the files where 0 bytes in length (probably a hard disk problem on my computer)
After trying a lot of stuff (installing stock MIUI, putting the phone in diag mode and installing a bunch of drivers), I managed to restore the IMEI number, but the phone still can't connect to the network.
I have tried a SIM from another company and it doesn't work. And my SIM works correctly in other phones, so I think that is not a SIM problem.
I don't know what to do... I tried flashing different ROMS, tried flashing a new baseband radio, but I can't get it to work! Is the phone lost???
Can anyone help me? I would appreciate it very much!!!!

Hi
I´m a little new to flashing roms etc, I have an LG G2 D800 which was on AT&T in America, here in Spain it is on the Vodafone network. I followed the procedure to flash the custom rom by Rashed97 with accompanying gapps and other zips (Supersu). Everything went well until I rebooted, during the setup procedure the operating system tells me that I can´t find or recoginse a sim card even though it is in place. I repeated the procedure but it still says there is no sim card and I´m not sure what to do, everything else wifi etc works fine. Whats the best thing to do, change to a different rom?
Thanks in advance for your help

HI Friends, (@Vinay)
I am new here, and have specifically registered to seek your help
I have D2212 IN version which was SIM unlocked.
Apparently, I was successful in
1) Unlocking the boot loader
2) Installing Vinay's Custom Nitrogen ROM
Subsequently, I used the phone happily for over 1month and problems started happening where Phone lagged so much that it became unbearable.
Also at the same time, I noticed my phone would lose its network.
I would get a X next to SIM indicator. No Signal. I swapped the SIM into other phone, the SIM works fine.
I put other working sim in the E3 D2212, again no Network. No Data (2G, 3G). Only WiFi works
So I decided to roll back to D2212_18.5.B.0.26_Customized IN.ftf via Flashtool
Still no dice. I still see no network.
When I hit *#*#7378423#*#*
I think (repeat think) the phone is SIM Locked.
No matter which slot (1 or 2) I insert it, I don't get Network or DATA
But I can certainly vouch the Same Vodafone IN SIM was working on the phone earlier.
Any help in this regards is greatly appreciated.

Did you flashed the stock rom correctly?
Well I thought so
HI @vincy009
Many thanks for responding. Appreciate your help.
Well I thought I did.
I referred to a few youtube videos to do it using flash tool.
Also, pls note, I also tried flashing back Vinay's Nitrogen ROM, that too would not get Network.
So,it was 100% issue with the way I was flashing the rom (Stock or other)
Eventually, I surrendered and sent the Phone to Sony who refused to fix it citing it to be out of warranty due to unlocked boot loader
So I had to submit to a local Mobile repair shop who fixed it.
But I am yet to ascertain what exactly he did.
In the mean time, I have already read the Newbie's Q&A and other threads where they explain how to use flash tool.
If there is an accurate thread/howto/etc, pls point me to that, so that I can avoid mistakes in future.
Maybe you done something wrong in flashing step or it wud have been any Lil hardware problem.. If wanna do new things always get a nandroid backup.. So it wont get mess up.
