[Q] No SIM Card

I just got my Motorola Defy (from amazon.de)
Software version is Blur_version_2.51.1.MB525.Retail.en.DE
My Vodafone SIMcards don't work (tried 3, a prepaid non-UMTS SIM, my normal UMTS SIM and the SIM they exchanged at the Vodafone shop) , but a KPN SIMcard works. Phone shows 'No SIMcard' in the screen.
Does anyone have any insights or help ? (or does the Defy flat out not work with Vodafone NL ?)

Update, also doesn't work with a T-Mobile (NL) SIM.
Is my Defy broken ?

Added a screenshot

Looks like the SIM reader is faulty...
If it's under warranty, get it replaced.

Thanks
I applied for RMA and Amazon.de is sending me a new one tomorrow (hope that one yields better results )

No problem! I hope the one you get is problem-free.
The Defy is a great device but hearing things like this gives it a bad rap. If Moto can iron out all the manufacturing problems as well as all the other problems, they'll probably get more sales...

However, anyone who does some research before making a purchase, will know that any phone or even any electronic device out there, will on occasion have a bad apple amongst the bunch. Manufacturing defects are virtually impossible to prevent completely - it is what warranty is for.
If prospective buyers would not buy a device based on the experiences of a fraction of the consumers, they would simply never be able to buy anything.
Ask enough people and you will always find someone who has a problem with any product out there.

No SIM insterted, advices please

Hy guys,
I have a situation and need some advices
I have the opportunity to buy NOTE2 for a very fair price, BUT device cant read a sim card :-S (with sim card inserted)
Device does not have a waranty (because it is bought out of my country, to be specific it is from austria), and seller said he is not take it to a service center. so there is no diagnosis what is wrong with it.
I have not seen the device yet, but i will see it in about two days. Seller said that the device is almost new, and it is fully functional except the sim card.
I was ask him is maybe sim slot is broken (people cut regular sim card, and stuff), he said no (he also not sure, because he exchanged it for something else etc).
But nevermind, I will see if it is hardware problem (lets say that I am experienced in this ). I would like to see broken sim card slot, because it is replacable . But lets get to the part where I need advices. possible software problems
I read through forum, and there is various problems and solutions, and also there are few with no solution
I need help with my check list:
1: I will check the IMEI. If there is no one, I will give up
2: If there is IMEI, lets say that there is a chance (maybe someone flash a different rom etc). My qouestion is: Will I be able to make a proper backup of EFS? ,Then try to flash different, modem, kernel, rescue rom, etc... Without a chance to loose IMEI? (properly getting back with efs backup)
3: I read that there are few guys who bought a retail version of the note (the one without radio chip at all). Is there a way to recognize such? (i dont remmember if this version have imei, or not)
4: Is there a chance that device is only locked. What message appear in that situation (no sim, wrong sim, type unlock code or something similar ?)
5: What are the chances that maybe the radio chip is blown , If we assume that the device is relatively new and not dissasembled or something (I know that this is hard to recognize, but maybe, some services code or something)
6: Is there a some kind of service mode to check if the radio chip is functional
So to conclude: If you guys can help me with the check list, feel free to add tips.
I am sorry for this long post.
Thanks in advance

wow, posted a question last nigh, and now it is on a third page lol
lets bump
So once again, my main question is: Is there some service code/mode to check whether the radio chip is functional/or whether is the radio chip existing in a device?
the rest I will leave to chance
again, thanks in advance

Go to a your local telephony service provider, give them the phone's IMEI and inquire about it if it has been black listed. If your device's IMEI has been blacklisted IDK if there's a tool to clone/change it to a newer one. Once the device's IMEI has been blocked, that process is irrevocable unless the previous owner clears the issue for you.
Blocking IMEI happens usually to phones with unsettled payments for the phone unit.

Thank you, that is sound intersting, and when I've thought about it can be possible cause.
This device came from Austiria to my country, so If we assume that the IMEI is black listed; Whether this can be checked by any carier/service provider? or just one where phone is bought?
thanks again

if it is carrier locked then you should still able to dial emergency number isn't?
in hardware issue you can't.

Just like what dr.ketan said(which is the easiest way to troubleshoot it), try dialing the emergency number wait for the ring(a single ring, then put it down - don't try to call again if it does ring) and if someone answers your call - say the matter has been solved. The phone is network locked.

Thanks guys, I was reading a lot through forum, and my head is full of ...:laugh: so I overlooked the logical solution
Thanks again, will try check phone maybe tomorow, and I will let you know

[Q] IMEI - Can I change it on my SGS3 - I747M

Hi Folks,
Here is my situation, I have a SGS3 I747M which got water damage because of ATV accident, my carrier Virgin Mobile Canada wants $340 to replace it because I am not due for an upgrade yet! I bought another brand new SGS3 I747M for 1/3 of the price only to find out that the IMEI has been blocked by Telus because the phones previous owner canceled her 3 year contract prematurely.
So now I am screwed both ways! After several days of trying to wipe and re-image the phone I finally got it unlocked but once I put in my SIM card the phone tells me that I am not registered on mobile network, if I put it in my old phone it works. So, my question is can I change this new phones IMEI number to the current one that I have?
Any help would be appreciated.
Cheers

Your best bet is switch motherboards. Open it and take out your motherboard from the working one and put it in the other one. Someone in a cell phone repair shop will do it for you if you cant.

I would but the problem is with the MB, the phone heats up and last only 4-5 hours on one charge, even with new bat. The camera too does not work even if I replace the actual camera with he other phone.

This topic is not allowed on XDA, and is a crime in many countries.

Nexus 5x pick no service

my lg nexus 5x recently went to become just a personal compact computer that unable to make or receive any call or connect to network, not a phone as smartphone as it should be. everything work just fine only that it not pick up any service. it has detected the sim card is inserting and the carrier name of the card (it's AIS, i'm living in Thailand) but still the bar is empty and its IMEI is still good. After several investigation and tens of flashing which doesn't work, I came across with some clue of the causes of the problem and I'm begging if someone has a solution for it.
1. i found that in Thailand the LTE band that is support here is only band 1 and and band 3 which in this device it support only USA, 5 and 7 so is anyone know where to get a radio.img file for flashing it to make it work?
2. when I brought this phone it said it the description that it is unlocked, but I not sure its really is or not, so is there any way to check on that and a way to unlock it.
3. i'm quite certain that isn't a hardware problem as it's still able to detect the card i put in, so if it a software problem and someone know a clue of solution, please post in
thank you

1. Has it ever worked? Does it work on 2G/3G as the websites I link below say it should? The actual phone or simcard could be at fault here. But some info: If its not the international version and your carrier does not use the same bands then there is no software fix for this as it has to do with the hardware make up. Eg If the hardware cannot see band 3 no software with make it do so.
Here maybe some helpful links
https://www.frequencycheck.com/compatibility/k6lh22/google-nexus-5x-lg-h790/thailand
http://www.droid-life.com/2015/09/25/nexus-5x-hits-fcc-with-all-us-carrier-bands-including-verizon/
My suggestion, Return it and get the international (h791) model.
2.Unlocked in the fact there are no carrier/manufacturer restrictions preventing you from modding or preventing you from going to another carrier other than the one you brought it for. EG Moding a samsung device is a nightmare as carriers/manufacturers prevent you from unlocking the bootloader/installing recovery's etc and hacks are required to get around this. LG/Google allow this. 2 easy steps to unlock the bootloader and you are away.
3. It maybe the fact that the information maybe hardcoded on the simcard.

Thank you for your solution. It seems likely to be the first one as it has said in the description that it is the h790 when I brought it from eBay, and when it came and after I refurbished it, it never pick up my carrier's service since then.
One more question, is there any way to test the signal receiver function as if its still functional or not, by simulate US signal or something, because I may want to sell it to US someday and I want to make sure that it is actually work.

The only way to test it is to use it on a network it supports.

Question A52S/sm a526b/ds successfully rooted with camera working+ demo unit baseband 0000 imei question problem.

I purchased this phone unknowingly that it was a demo version.
I removed the demo version from it via the code, reset and then flash and update.
The dual imei numbers are both 0000 when I typed some code ( cant remember it showed that the imei is ok)
I wanted to get it repair via some of those remote box services. I dealt with very rude unpleasant person who was impolite, told me to install quite old xsg rom which is different csc compared to my original rom. When I flashed under imei there is UAE csc and new lines added under: TRA ID :
and TA : , and these two were not there before, device also shows just as a52 instead as a52s as previously. The person suggested the rom based on the build number that I sent him.
Afterwards he was asking for pictures and then blocked me.
Im wondering If I can fix this unit to usable cellular state with working real imeis
I thought xposed modules would help, but it seems they only help with apps and only change imei on them.
I highly doubt that this device has banned imei.
I would be happy to help you to root it and I would appreciate if someone can help me.
I searched many threads without success, I know the efs/qcb is probably corrupted
What route I should go to fix this device?

If it is a demo version and has no IMEI this tells you that this legally is no mobile device that is approved to use with operators. Inserting a new IMEI can not be legal in normal countries. IMEI is a device identifier sent with all phone traffic to ensure that the device is a legitimate one and is not stolen and black (do not work at all) or grey (works but flagged to be traced) listed.
Go back to the seller and demand your money back!

I hoped that someone with more experience with this would chime in, on these new galaxy devices the imeis still seems to suppose to be there, in galaxy 8 or older galaxy version there was no 4g module and antenna removed, I think this is what you are talking about right ? and it was purchased on ad.
Im wondering if these services like chimera can fix it.

I thought it's unrootable. How did you do it?

You must be joking; demo phones have no imei. They are not phones they are dummies. Throwing around inane accusations will do you no god around here.
