You can purchase used motherboards on eBay but they may be hard to come by. Generally a used MB either has a bad ESN if it is carrier branded or it has something else wrong possibly water damage. What is wrong with your signal? Why are you trying to get a new MB

IMEI would not be blocked the phone sells fully unlocked. Try to
1. Do a hard reset
2. Flash new stock firmware via Odin
3. Try a different SIM from another carrier.
4. Try to restore the IMEI EFS NV-data.bin file.

I believe Philz CWM has an option in recovery to restore your EFS check here
Hopefully a backup exists on your phone if not your going to have to restore without a backup. Search the forums here on how to restore without a backup if that does not work

poped my EE sim in phone found a good signal spot ,strange i can get data downloads but no voice or sms ,puzzled now

Your better off calling a carrier (3, t mob etc) ask them to check the imei. I brought 1 off ebay, worked great for 2 weeks then lost signal, tried loads of sims, some showed signal but wouldnt let me make or recieve calls or txts, searched online if the imei was blocked and just got msgs sayin "valid" in the end called 3 even though the phone is sim free but was sent out with a new 3 sim, they told me it had been blacklisted as a fraud case and the phone will never work and to bin the phone. This gave me a challenge, brought a 2nd phone from the states with a broken screen (US blacklisted imei can sometimes work in the uk) chamged the boards and now have a working s4

Repair Samsung Galaxy S4 IMEI – Fix Galaxy S4 GT 19505 IMEI error

After repair my phone from bad boot, as it was stuck on the attached image i repair it through kies. but now it's showing IMEI problem. it's showing NULL

That's forced download mode. First thing you need to do is flash a stock rom (preferably for your carrier) with Odin. Then, if you're lucky, you may get your IMEI back. If you don't & you don't have an EFS backup, it's either a service centre or local mobile repair shop job.

That was only for samsung galaxy s4 I9500 not for I9505.

I had this problem when I first got my s4 I flashed a ROM everything went fine I booted up and imei was null, so what worked for me was booting back into recovery and wipe everything and restored my backup and all was good again!!

No one that is smart will share their IMEI code with an other person. I would highly recommend that nobody should share their /efs backup.

A bundle of thanks dear, for nice suggestions and advice,
i hope , everyone will listen to you.

I hope they do, because nobody should share their efs.
If you don't have backup then you should get acces to a samsung box: http://z3x-team.com/
If that doesn't work then you have damaged hardware.

Permanent no service? No connectivity?

Well i was trying to to flash a new rom on my D802 and accidentaly i deleted everything... a full wipe from phone menu ( not recovery )
Since there was absolutely nothing on the hard drive anymore ( i assume) Phils TWM coudnt find any folders .. i had to push roms to the phone through adb now the problem is that no matter what rom i install i get no connectivity/no service .. cant recieve any calls or use data... only wifi...
I tried re flashing...
Stock rom
Paranoid rom
G flex rom
Stock kernal and peak 5.2 kernal
Nothing has worked? How do i restore connectivity to my phone? Thanks

You have a problem.. Your EFS folder was probably wiped
I guess you could reflash your kdz and bring it into the service centre?

I bought this phone through Kogan shipped from hongkong... This will take weeks, perhaps months... I am not even good with reverting phone back to stock as if never happened...
Is there any other way for me to fix it myself?

Anyone.?

there are plenty of guides on xda on how to revert to stock. search these forums and read carefully. you will be back up in no time. there is also a thread on stock modems also. give it a whirl

NomadCF said:
Honestly, you'd need some one to send you their EFS backup (who's on the same carrier and model). Then you'd need to extract it. Then edit it to replace their data with yours.
But I don't think your going to find anyone willing to do that. As it's a HUGE risk to them. So I think your only bet it to to a warranty or repair 'call' with lg if not your carrier.

Is there anyone who can help me with this folder? You can remove your sensitive info... I have the international d802 bought from Kogan Hong Kong stock been using with optus network in Melbourne Australia. Will really really appreciate it.

I don't think editing will help. Don't know if you can even do that.

Warranty service?

Yeah, if you wipe your EFS, flashing back to stock wont help. The EFS partition contains files individual to each device, you will probably have to return it for repair man D:

I've had the same problem too, my SIM card doesn't seem to be reading on my phone either; and it definitely a functional sim.

I'm sorry, xda mail somehow has been going to my spam folder.
Anyway I am not familiar with this issue, but perhaps you can restore your stock rom via flashtool, then call LG and tell them that you don't know why this happened Oh and modems are distinct from EFS I think (at least that's my understanding)
Your main problem will be the shipping though
I found this thread for the lg optimus G though - http://forum.xda-developers.com/showthread.php?t=2161498. Perhaps try PM-ing autoprime?

Same Problem
I also am in this EXACT same position. Still havent found a resolution quite yet. I am in correspondence with Shellnut the guy who actually wrote the freegee app that uses loki to flash cwm and twrp. He said that only cdma phones need efs, that the gsm phones didnt need it. This was new information to me. I haven't heard back from him quite yet as he informed me my phone wasnt bricked and that they would help me get back up and running. I know he is extremely busy. I have also been hearing that you can possibly use lg qpst to manually write your imei, looking into this now.
I would love to not have to take the risk of sending it in. Would love to just fix it.

i'm in the exact same position right now. Hunting the threads for a fix. I will be going back to Hong kong in 2 weeks time for 2 days, not sure if thats sufficient time for LG to get it fixed.
Hopefully we can find a solution soon!

Possible refurbished device with incorrect model no., need help from experts

I'll be quick so no ones time is wasted and a viable solution can be found fast.
I bought a D802 from a third-party, with:
- 32GB ROM
- 4.4.2 D80220b firmware
- 2G, 3G, 4G working
- The csmg.lgmobile.com website said that according to my IMEI, my model is the UAE 32GB D802 and gave me the D80230a firmware for manual flash via LG Flash tool. (screenshot below)
I used the phone for a while, rooted it and used Xposed. Never got recovery so no backup(wish I'd seen the SRK tool before). Then I downloaded the firmware from the csmg.lgmobile.com website. I flashed it via the Flash tool and everything seemed fine. Then it booted:
- Touchscreen was erratic. Ghost touches, dead spots, phantom touches, whatever.
- The Baseband Version and IMEI in About Phone both say Unknown
- ROM has converted to a 16GB version
- Download mode is fine along with every other feature of the phone
After that I looked around and found a UAE D80220c firmware and flashed that. It flashed fine but all the above issues remained the same.
I browsed around extensively here and found out:
- Refurbished phones have their back cover and firmware changed to imitate D802's.
- My phone is probably some other G2 model with D802 firmware and an altered IMEI
- The actual model of my device is UNDER the motherboard. Which, apparently, I must get hold of so I can flash the appropriate stock kdz. This gets a bit too hardware-y for me.
So, basically, my phone is no more useful than a brick at the moment. Any expert help would be appreciated but here are the main questions that I'd really like answered:
A. Should I try various flashing the kdz files from different models mentioned in the link I gave up ^there until one clicks and then try to do something about the IMEI?
B. Is there any chance that my phone is beyond repair forever?
C. Should I stop messing around with my mediocre knowledge and take it to a repair shop?
I really can't afford to lose this phone so please, if you've stumbled upon this, try to help or forward it to someone who CAN help. I will be very thankful.

Cannot really help you. But look for Frankenphone. There's a thread here.
I would return the phone. That's fraud.

Go by this method.

B. I doubt it's beyond repair, it will just take you time and work to figure out what is what and how to get it back to working state. I think everything you need can be found already here, I saw a lot of posts with the similar problems and really hard bricks being solved. Just be patient and good luck.

You have to confirm your mobile actual model. By opening it back cover.

Possible refurbished G2 D802
Guys i bought an LG G2 D802 from a third party. i tried to install TWRP using AUTOREC for D802. My phone went into a bootloop. Luckily i had made a backup with SRK tool, so my G2 is up and running. I think my phone is refurbished because i have seen other G2's with D802 backcovers in that market but their IMEI no. was D800. My IMEI no. , backcover and software all say D802. I Dont want to open up my phone because it is confusing for me because i know there will be 2 to 3 model no.s written inside it. My question is can i find out my model no. by installing all autorec recoveries for g2 on my phone after making backup on SRK Tool. When i get the TWRP recovery on my phone i will know which model my phone is. Plz people who are expert of SRK tool help me...
Also will my Imei no. stay safe if i backup from srk tool.

Backuping EFS partition will backup data like device specific essential information such as the IMEI (International Mobile Station Equipment Identity), wireless device MAC address, baseband version, product code, system ID and NV data.
If you lose your IMEI during flashing and wiping roms, you will end up with a piece of brick incapable of making calls:crying:
