Successfully transplanted a motherboard from donor phone - and it looks like I am good to go. Now need to unlock the phone to use my non T-Mobile sim card.
Can anyone tell me if I use the original IMEI number - or the one from the transplanted motherboard / phone ?
Is the IMEI associated to the motherboard ?
Any feedback greatly appreciated
i believe you have to use the one from the donor motherboard since the old dead phone is no longer the IMEI for the new phone sir

and today when I was looking into unlocking my phone, I noticed that the system IMEI is different from the IMEI label on the back of the phone.
I am using a deep shining ROM. did the ROM flash over the IMEI or was my phone just messed up to begin with?
also is there a soft method of finding out whether or not my phone is already unlocked?
Sorry to say but that guy messed your over by changing the IMEI. Flashing a rom doesn't do anything to IMEI, special tools and software CAN change it, and that is what this guy did. You can't do anything to change that, as changing IMEI is downright illegal and you dont want to get caught up in that.
As for finding out if its unlocked, take another companies SIM CARD, ie if you are with ATT, go and get a Rogers, or whoever else uses a SIM CARD, and find out if it will work in the phone.
so, it is quite possible that this phone is stolen? damn... what are the potential consequences of that? if he switched the original IMEI to the current one that I have, what if someone legitamately uses the imei on the same network, am I going to be screwed?

No you will not get screwed. {Unless you really want to; then I'm sure we can arrange for it}
IMEI {International Mobile Electronics Identification} Numbers are uniqe to every phone, but the network does not {& I believe Cannot} read the IMEI. ESNs {Electronic Serial Numbers} are a different thing, as the CDMA networks use this # to Identify the devices network authenticity {in other words: Whether or not it's authorized to use the network}. GSM {Global SIM Management} Phones rely on the SIM card to authenticate the devices access to the network. An IMEI is never sent thru the network! That's like posting your social security # online {Mine's 420-69-840} About the only time that a false IMEI is a problem, is when you need to get it unlocked {as you are trying to}; or if you need to report it stolen/lost. If the latter is the case then you will need to provide the authorities with both IMEIs. This is in case the person that has it removes the label in the back. For unlocking the device, you need to give the # that's in the software; as this is the only # the phone knows. Oh yeah, You can't send it in to get HTC warranty service either
Have you tried asking the person you bought it from about this? I would!! I would want to know why he did it, how he did it, & where the other # came from. It is a possibility that he had replaced the Mainboard with another unit, but he should have changed the labels at the same time. I have done this with a few phones {combine a couple bad ones to make a good one}, but I always ensure the IMEI or ESN matches on the back & in the software! If you believe you were defrauded, then contact the authorities & explain it to them. If there is another phone with the same IMEI, they should be able to tell you.
It might either be that he changed the main board or the cover itself.. (hopefully he did not steal it..)
I wouldnt worry too much about it though. Just go with the IMEI that is displayed on your screen not on the back of the phone.
well i tried to get an unlock code by using the IMEI read off the system page on my diamond and the guy couldnt get aan unlock code; is there anyother way to get the correct code>?

Hi,
Maybe it is or it isn't (but it is possible). It depends on which country that person bought this phone and maybe he used warranty service. I had this issue myself.After 2 month My Diamond didn't recognize my simcard, i sent it for warranty and when it came back GPS didn't work. so i sent it again , when i received it, at repair center they said that they replace mainboard, so imei changes and i received written document that they replaced mainboard (my back panel imei and the imei that phone shows are different now).
for checking it , Goto this site : http://www.numberingplans.com/?page=analysis&sub=imeinr
enter both imei and check them, if both are for diamond i think your mainboard is changed before, but if the imei that phone shows is belong to another handset (for Ex : a nokia one or another htc model) i can say 99% percent your phone is stolen.
i'd probably bet he's bought an "original" housing from auction site. i've done it many of times but i usually rip the imei sticker off, bear in mind the imei on the diamond is only on a metal plate, he may have forgot to change this part, he may have damaged his old imei sticker/plate, as stated above he may have changed his main board also, there is many possibilities.
don't worry about it, if your still a bit worried try the CheckMEND online service here:
http://www.checkmend.com/uk/
It costs £1.99 per go, (which you'd want to do both imei's) but you get a certificate telling you wahts dodgy or not about your phone.
it a great service if you feel a little worried.
Hello Guys,
My G1 is Bricked, Have an Question,
As we know the JTAG De-brick stuff is under development, so the curremethod is to change the motherboard...
So My Question is If I get an Screen Broken G1 & Replace my Motherboard with its Board, will it change my IMEI number ???
yes (10 char)
And if the screen broken g1 is sim locked to some network, would it lock my g1 after swapping the MotherBoard ?
your unlock code corresponds with the IMEI number, so yes, the new board would need to be unlocked for any network other than tmobile. (or whoever the phone is subsidized through.)
I know I have other threads on this but decided to give all my symptoms and what I have done up till now in one thread.
Ok, so to begin........ I had the power button problem on my Captivate as well as other problems, phone would get hot and smell and do weird things. So I decided to buy a broken phone off ebay and change out the motherboard.
I swapped boards and the new board had a lock on it so I couldnt get into the phone so I restored it to factory defaults. After that I was able to get into the phone and it works great except for the fact it will not connect to the network! So I have a camera and a wifi device.
Here is a list of problems I see.....
When phone boots up without sim card it doesnt ask for a sim card to be inserted
when sim card is inserted it doesnt read it (card and card holder work fine on other motherboard)
No network but wifi works fine
Baseband version - unkown
phone number - unknown
mobile network type - unknown
service state - out of service
mobile network state - disconnected
imei - unknown
imei sv - unknown
I have tried pretty much everything I have read on the forum....
Rooted phone and installed a custom rom and corn kernel - no luck
Mobiletechvideo method - no luck
moved efs folder from old motherboard to new motherboard - no luck
did a CWM backup on old motherboard and copied it to new motherboard and ran CWM recovery - no luck
tried Galaxy S unlock and no matter what I do only get the FFFFFF code
Flashed other modems - no luck
in hex editor my nv_data.bin files look fine.......
00188008|2e|34|00|00|00|00|ff|41|.4....A
00188010|54|54|00|00|00|00|53|47|TT....SG
00188018|48|2d|49|38|39|37|5a|4b|H-I897ZK
00188020|41|41|54|54|00|00|00|00|AATT....
So anyway, Im at the end of my rope so hopefully I can get some insight before I just give up (which I keep saying I'm going to do but havent yet, lol)
Thanks!
It may not matter, but have you tested someone else's SIM card in the phone that's not detecting yours? If it won't read two different cards, but all the software parts are looking like they're functioning correctly, it's possible you have a lemon SIM card reader.
I don't know if that's something that could be replaced, but if you test it and it won't read the second card, it might be worth getting in contact with Josh (connexion2005) at mobiletechvideos to see if replacing the SIM card reader is something they can do.

Yes I have tested other sim cards and they dont work either. I had thought of this too but I put the sim card reader/holder on the other motherboard and it reads fine.
Here's an interesting twist......
started looking around in root explorer and looked at dev/block, only folder in there is dev/block/void and it is empty. Maybe this could be the cause? If so anyone know how to fix it, lol
This very well may be a modem defect. Do you have the background story for how it became this way?

It was a phone with a broken screen I bought off ebay, took the motherboard out and put it in my phone which has a bad motherboard. Hasnt worked since I switched it out so that as far back as I can go. If it was a modem defect would the wifi still work?
my At&T Htc one m7 is unable to detect the sim card. It doesn't even show an error in the notification window almost all of the time, sometimes when i get the notification error (no sim card) i insert the sim again and it works. I tried the tape fix but it didn't work. Tried bending the tray a little that didn't work either. Tried using a nano-sim with a micro-sim adapter but that also doesn't work. Even when the sim card is inside the option to search networks is greyed out. I'm in India bought it on eBay in Dec'14. The HTC service guys are saying they cannot repair AT&T at all. What can be the issue ? Is the sim card reader faulty ?
I'm running Lollipop 5.02 stock with S-OFF.
Any help is appreciated.
Thanks.

I would strongly recommend not bending the tray, adding tape or using sim card adapters. All these things can make the situation worst, many members got their sim tray stuck inside the phone because of that.
Backup your files and try a factory reset first
If the phone isn't stock, you should flash back the stock rom
Also try with a new sim card
If nothing works its maybe an hardware damage and you'll need to send the phone for repair

I'm fully on stock, tried factory reset, tried with different sim cards (with a brand new one too) but nothing works. Problem is I don't know where to get the set repaired in India as the HTC service center refused to service it saying they won't get the parts for AT&T. Can sim reader be a problem ?

Not the first time I see this. Its a cheap excuse because they don't care/want to provide support for devices that were not purchased locally. I can't believe it's impossible for a big company like HTC to get the parts from the USA center or even directly from the manufacturer from Taiwan. Anyway it might not worth it depending the cost of repair, a brand new M7 cost around 200$

Maybe it could also be anything else like the radio or the motherboard, its hard to tell.
Got it rectified .. it was an issue with the imei .. the number just sometimes went blank because of which all this kept happening .. wrote the imei again and it's working fine since a day
Thanks ..

Sorry for the late reply man, nothing got rectified, I even got the network IC changed. After a day it became the same again. Sold the set as the HTC guys in Delhi said the motherboard needs to be replaced.
Were you able to solve the problem ?
Hello, I'm considering to buy chimera to do the job, I have no box nor dongle. But I still can't figure it out how to get a new IMEI number. should I use an IMEI of an old phone? is there a list of unused IMEIs ? How does this works ?
