OPPO NEO 3. No sim card detected - General Questions and Answers

My phone is rooted
Before this problem :
I flash my own port Rom using cwm.
And no problem on my ported Rom.
After I decided to flash another Rom it's ok nothing changed but when I flash ported Xperia Rom from the owner (not me) ,and I get the problem. No sim card detected.
I don't know why, but maybe because the Xperia Rom is cdma gsm, so my phone can't detect that because my phone is gsm gsm.
After that, I flash stock Rom and the problem still there.
Please help. Thanks

Hey there..
I would recommend you to download the stock firmware for your device (search "firmware for (your device's baseband number" on Google) and then flash it on your device using Odin..
Visit this http://forum.xda-developers.com/showthread.php?t=1896696 guide for tutorial on how to flash via Odin.(Only follow the process don't use the download links provided as they aren't for your device)
If even that doesn't work, you might want to check whether your sim card is defected or not by putting it in some other phone..
Cheers.

Hey there..
It seems that there is a problem with your sim card slot.
I would recommend you to take it to samsung service center as we are unable to offer you technical assistance on this matter.
Good luck..

SIM not working

Greetings!
I bought Magnus last November and everything seemed to work fine until now.
The phone is now not recognizing both SIMs simultaneously.
First I thought it might be a hardware problem with the SIM slots but have made sure that both the slots are working fine and so are the SIM cards.
I found out that the SIM 2 gets activated only when I turn SIM 1 off in the SIM Management settings, otherwise there is no network recognition.
I’ve also tried removing recently update apps etc but alas!
Any ideas or anyone went through the same before?
Thanks in advance!

I am giving some shots at home before I go to the service center, its horrifying!
Last night I did a factory reset on the phone but alas the problem still persists.
Before flashing it, can I try Hard Resetting it? Will it make any difference?
Thanks in advance!

Working link for the Stock ROM?
I hope it will not be different from the one that is pre-installed.
Another strange behavior which I noticed today:
(Original SIM Cards: SIM1 : Vodafone, SIM 2 :Reliance)
I swapped the SIMs just for the sake.
But this time instead of SIM 2, SIM 1 is showing the same problem which is Reliance in this case.
Can there be a problem with the Reliance SIM Card?
Will be testing it by replacing a 3rd SIM soon.

Bro Bro listen......
I think there is problem with your Reliance Sim card..Phone is working fine...IF there were any fault in the Phone in the SIM 1 then it wouldn't have detected the Vodafone Sim...
BTW try With a new Sim..Until then no need to flash the stock Rom...
If the problem persists then just comment here..will try my best to guide you

I tried another SIM as SIM 2 & Vodafone as SIM 1. It worked fine & the original Reliance SIM is working fine on another phone as well.
I called up the Reliance Service Centre, told them about the probelm & they said that this is some network issue & my complaint will be resolved within 3 days!
Now the problem is beyond my understanding, as I swapped the Sim cards again, Vodafone as SIM 2 & the other one as SIM 1
& to my surprise it is not working and showing the same behavior although it was working fine before!
The original Reliance SIM is still working fine on a separate phone!
Now what bothers me the most is, Is that even possible to be a network error?
But I can now give a try to flashing the stock ROM, but I need to be assured that it'll be the original ROM and will not void my warranty.
If so, then please provide me a working downloading link for the same as I have already downloaded SP Tools!
I just came across this post in the forums:
" Try downloading mmx canvas stock recovery from below link and follow steps.
http://forum.xda-developers.com/atta...1&d=1370782052
Put file recovery.img in your root of sdcard
Use MTKDroid tools to flash it instead of MobileUncle Tools"
Will this help or the original ROM?
Thanks in advance.

SOLVED
Sorry for being a little late.
The problem was with the Reliance network!
When I called them up they said they will look into it.
And weeks later they called back and said that this is a very common problem which has now been solved and they refer to it as
" Cross Connection Error "
I don't know what the hell is wrong with them!
Anyways, thanks a lot for replying.

Root ics with CID error

Hi
Can someone please help? I've an ICS on atrix 2 running at&t ROM official on Indian Atrix 2,unfortunately I've lost my CID & getting cid error on boot & want to bypass it with bmm
I searched many threads couldn't get fix.i want to root my device and I was told to root using BP tool,I've no clue how to root using bptool as I've tried one click ICS root which didn't help,if someone can guide me or provide a link how to Root using bptool & also I need a bmm apk file as playstore doesn't have it,please need help.I'd really appreciate all the help
AFAIK, if you have not backed up your CID, you have to live with that error
Each phone has its own CID
Thanks for reply,my concern is rooting,how to root ICS when I've cid error can you help me I was told using bp tools I've no clue how to root using bptools
Pls see this post, part number 2
http://forum.xda-developers.com/showpost.php?p=61919769&postcount=19
Many thanks I followed your procedure & rooted it,one more question here as I've an Indian atrix 2 MB865 but flashed ATTversion I'm getting sim not found error,is this cause of flashing at&t or some other reason,here is the thing
I insert a micro sim of one carrier by Name Aircel it detects for sometime & again no sim card
If i insert normal mini sim card of mostly all the carriers ive tried ,it'll not detect my sim no matter what i do
Ive tried both 32k & 64k sim.i believe atrix 2 has mini sim,but still don't detect mini sim,but it detected micro sim for couple of hours
Sim I've used
Aircel -micro sim worked for 2 hours
Aircel - mini sim didn't work
Vodafone - mini sim didn't work
Docomo - mini sim didn't work,
Could you please help me,should I reflash Indian fxz? Or is it just a radio problem? Could you link me to correct fxz of Indian version please as I've already messed my phone with cid not saved,also if I flash back to Indian fxz will I've any problems flashing as I've CID error?last thing should I delete Boot menu manager & unroot before flashing? All your help highly appreciated
Regards
1. You're sure that your SIMs work, right?
2. Because mine is AT&T, so I don't have any experience flashing cross ROM
Here're what I know from your post:
- I think you can use alcohol to clean your SIM holder
- You don't need to remove BMM or unroot before flashing, just flash it by RSD, like you raze your house and build a new one, you don't care what are inside your home :silly:
Thanks again,I've flashed back to Asia retail using the bat file without using rsd lite,thanks to the developers ,makes things so easy,coming to the sim issue ,even after rolling back to Asia retail the sim problem still there,not detecting sim.it only detects one particular carrier sim that's aircel & its a micro sim whereas our atrix2 has mini sim.I'm really confused now,where am I wrong
You said clean sim holder as in the sim card slot which holds sim card inside the phone or do I clean the sim card ? The chip portion?
Do you think the sim tray is faulty ? If faulty it wouldnt detect any sim ,but it detects micro sim of one particular carrier,I'm sorry to throw so many questions at you,really appreciate your help
Hi,
I meant the golden contact points of your phone, just clean it for sure
But if you already flashed different ROMs or tried many SIM cards then I think there must be problem with your hardware (SIM holder or something else I don't know)
Mini SIM or micro SIM doesn't matter, just the size
To remove cid err on bootlogo, you should try this: http://forum.xda-developers.com/showthread.php?t=2406867

Download the stock rom for your device, double check the model, its probably a bad modem error, where your imei and baseband is null. Flash it and get back your device alive.
