Phone System Info

Hello XDA-Developers,
How can I check the exact model of "Samsung Galaxy Note II". The IMEI sticker doesn't match with the phone (*#06#). I don't think it is the original model/software loaded, please help.
Label at the back of the phone is attached for reference.
regards,
kay8

Try to contact Samsung.

Settings --> About phone
There you'll find the model, SW version and so on so forth. IMEI, MAC and serial no can be checked under Status.

unfortunately, this feature is not in the settings menu, I also tried to set the unit to factory default as mentioned in this forum (volume up + home + power) but didn't work.
Is there any other way to find this units system info?
One more thing, Samsung logo is not shown during system restart.

No signal at WCDMA

then you need to downgrade to 4.2.2 and do the step and when you got imei back flash 4.4.2
if you are on new bootloader download 4.4.2 bootloader put it in 4.2.2 rom and flash and do the step and flash 4.4.2 stock again

I've tried EFS Professional and my IMEI is fine, not damaged in any way. This is really strange.

It seems that your Radio Information has gone. Mine says a date, but try this: type in dial *#27663368378#
go to [1]UMTS then to common then to nv rebuild and select load default NV if that does not work go again to nv rebuild and select nv restore

Thanks, mate. But I've been impatient and left phone in Repair shop. I'll know the status during the evening. Will update later.

They've repaired it with box.

LG G2 with null IMEI after crash

Hello
I have an LG G2 D802 that was working perfectly but some days ago, after a crash with broken screen the phone suddenly show the message "Service Disabled" and the code *#06# returns IMEI Null.
By the time of the crash it was kit kat, and I made a factory reset that did not solve the problem. After that I use LG Flash tool to install the lollipop 5.0.2 rom, but the problem remains.
Then I took a lot of time trying to understand the problem and I found out that it could have a EFS backup, but in fact I didn't have one.
The next thing was root the device (it is allready out of warranty) and use alternative tools. I have tried to rewrite the IMEI I have in the box with QPST , Qualcomm NV tools and did not work.
- QPST (2.7.4.11) works and shows the device but doesn't work the Backup QCN (To get QPST to show the device I needed to apply this with adb shell - http://forum.xda-developers.com/lg-...ct-g2-d800-t3175064/post62250384#post62250384, but it works and shows the phone in the ports list);
- RF NV manager returns and error "NvManager::getNvItemsFromPhone( const string comPort ) - QpstServer::sendSyncImpl - Bad response from phone (DM packet commands 19-24)";
- Qualcomm NV tools works and reads the device, then I write ESN, MEID and IMEI with good confirmation messages, but when I rebbot it remains with Null IMEI.
By this time I am in the search for more wise help and experience.
I also have "Unknown Baseband", and by reading some threads I thing the problem is that the phone has Null IMEI and the tools are unable to writr data to partitions. The only way is to write NV1 and NV2 by dd command into mmcblk0p10 and mmcblk0p11.
The phone works perfectly in all aspects (sensors, camera, wifi, screen) except for the phone signal "service disabled" with an X above the 4 signal bars. I gess it is not a hardware problem
I am struggling with this because it is a very nice device, and I need to bring it back to life before replacing the broken screen.
Any help?
thanks

Today I tried this method with adb shell, to make sure Qualcomm NV tool writes IMEI to the phone...
setprop sys.usb.config diag,adb
ls -al /dev/block/platform/msm_sdcc.1/by-name
dd if=/dev/zero of=/dev/block/mmcblk0p10 (no space left on device)
dd if=/dev/zero of=/dev/block/mmcblk0p11 (no space left on device)
dd if=/dev/zero of=/dev/block/mmcblk0p16 (no space left on device)
Can anyone tell me why the "no space left on device" occurs?
Thanks

Hello!!!
First sorry for my poor english!
I think that you have a bad connection after crash!!!!
1. Remove the Backcover of your phone.
2. Remove the backplastic on upper part of phone using screw driver.
after remove back cover and upper plastic
3. Remove Battery Connector.
4.Remove all connectors except camera connector, Proximity sensor and face camera
After removing connectors
6.Reattach all connectors! Firmly press all the connectors
7.Reattach battery connector!!
Et voilÃ*!!! This is a way I do after losing IMEI and Baseband! IMEI: null and baseband should be implemented!!!
I had tried most method to fix but nothing happens,
Hope to help you!

What should I do? If the same problems on RF NV manager got the same error. bad response from phone. How do i fix it?

Wow! What a coincidence!
I also have a LG G2 (D802) and the EXACTLY SAME problems!
Background:
It's been about a year since I am on Lineage OS 14.1.
Since 6 months ago, I started having issues with my antenna. Sometimes, antenna bar got empty and sometimes I couldn't get 3G signal on locations that I had before (and others had with no problem)
Fast forward 3 months ago and one day my phone couldn't detect sim card and IMEI was vanished. I had to restart it few times to make it come again.
And a month ago, I dropped my phone and screen shattered, Exactly Like you. After changing broken LCD with new one, and also a new battery, I couldn't get sim card detected anymore, No matter how much i restarted the phone.
IMEI was null and no baseband version was showed on about page. Also back of the phone (under camera started to get suspiciously hot.
I started applying pressure to different parts and sometimes phone hanged and restarted and maybe one in 20 times I could get antenna and sim card back.
Things I've done and their result:
Opening the phone numerous times and checked the connectors and unplugged/plugged them: nothing changed
Flashing back to stock (found lollipop kdz and flashed it via lg flashtool): nothing changed
Flashing Radio (Some images were available on XDA): nothing changed
Restoring ROM to an old backup I had (year ago): same as above
Trying to use QPST/NV Tools: They cant talk to modem.
Showing the phone to some repairmen: they cant talk to modem to set the IMEI either.
Still, sometimes by applying pressure to phone randomly, the IMEI comes back, which prevents me to cut hope and drop the phone into trash!
I would really love to know your result! were you able to fix it?

How to Fix LG G2 no IMEI and not detecting SIM Card!
After I posted this reply here, I found a solution on some other topic about how to fix LG G2 WiFi issue. He opened the phone, and applied constant pressure (by putting a tape between WiFi chip and Metal Cover).
And I thought maybe my problem is similar too. So, this is the things I've done:
Download the Service Manual for your phone model. you can find it on Internet. Here is the one for LG G2
Look at the Service manual and find the chipsets related to IMEI/Service Issue. Usually they classify board components based on their common issues. For example, in G2 service manual, in pages 38 and 263, you can see this info.
For LG G2, The chips/IC's related to IMEI and Service were: U2003 (Bypass Booster), U2002 (WTR1605L), FL1014 (B3 DPX), U1101 (SP4T B7), FL1015 (B2/B3 Filter), FL1010 (DPX B20), U1005, U1000, U1001, U2002.
Most of these parts are under a metal shield which can be easily unmounted and mounted back on.
Make a thick piece of Tape and put it between the chips and the metal cover. The goal is to apply pressure to them to stick to the board.
Put the metal cover back on and close assemble the board. Done!
In my case, it worked, although after lots of repair men simply rejected my phone, I fixed it with just a little tape. Now, the IMEI is back, SIM Card is detected the moment phone is on, and I guess the phone consumes less power, since it doesn't get hot anymore.
Why this works? Well when you use your phone for a long time and it undergoes a of of heat/cooling cycle, the pins of some of these chips that tend to get hot, become a bit loose and get disconnected from the board. by doing above instructions you simply push them back.

Lenovo k5 note lost IMEI and Serial Number

i used the SP_FlashTool_v5.1616.00 to download and update the firmware to marshmallow version 6.0.
i have used the "Format all + Download" option.
And it seems i have not saved the nvram and nvdata files.
now my phone boots and wifi and bluetooth works, but i have lost the IMEI and the Serial number and i can't use the SIM card.
it says No Sim inserted.
the help of your experts is highly appreciated, to allow me to recover the imei and the serial number.
(i have a snapshot of the previous original IMEI and Serial number)
thanks in advance.
