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.

In brief:
The N4 is stuck on the whirling circles during boot. It is likely due to some broken bit of hardware. I would like to determine where it's stuck. After that I can decide if repair is possible or if I don't need that feature and it can be skipped one way or another or toss the brick altogether.
In full:
While out of town S.O. dropped the phone and the digitizer shattered. She said the screen appeared to still work, but no input was possible. She ordered a new digitizer and dumped it on me to repair, little realizing the difficulty of replacing only the digitizer. Still, I gave it the ol' college try on a slow day at work, heating the glass shards to yield the glue and get them off the screen. After installing new digitizer I was not surprised that I had damaged the screen and just a few colored stripes displayed.
So I ordered and installed a digi/lcd assembly and I now have a functioning screen and digitizer. The problem is the system won't completely boot and is stuck on the infamous whirling circles. I am fairly certain that during boot some device is being queried and is broken, and the boot has no timeout to skip it and move on. I would like to know where it's stuck. I *think* the way to do that is to somehow direct kernel messages out the phone's USB so I can use PuTTY to display them on a workstation. I do not know how to do that. If there's some other way, like getting the messages to display on the phone's screen, I don't know that either. Hence my post.
The techie bits:
Long story short here's a summary of relevant actions I've done so far.
Phone still goes into the mako bootloader and I can use fastboot.
Used TWRP recovery to wipe everything (including itself)
Flashed factory 4.4.2 OS
Reinstalled TWRP recovery and had it root for me
I now have two ways to access the phone - fastboot when in the stock mako bootloader, and adb when I fire up TWRP.
Now what can I do to find where the system boot is hanging? Suggestions welcome.
first thing to look at - proximity / light sensors connector . phone will not boot if they are disconnected from mainboard.

I will check that. Thanks for the reply.
Edit: I just checked, and you were right on the money. The tab with the connector for that device had flipped under the mainboard so I didn't connect it. All fixed now and I have a working phone. I owe you a couple beers. Thanks.
Hi, you are lucky
I have a similar problem.
Yesterday i restarted my phone and >problem, stuck at X-boot-logo<
Already tried different roms.
Can get into fastboot-mode and therefore can have ADB with CMW-recovery.
I replaced my screen a few months ago.
Already checked proximity sensor cable.
btw:
at the beginning, one time I got it to "optimizing apps...", but it was stuck at "starting apps"
How can I see if my proximity/light sensor is dead?
can I use the Nexus 4 serial?
Any other solution?
Regards
You can try to downgrade to stock 4.2 android, phone most likelly will boot, but looks like you have lost your IMEI.

OK, I'll try to go back to 4.2.
Anything I can do if I really lost IMEI?
I think you could be right.
I rebooted my phone because i got no network connection. (even after airplanemode on/off)
---------- Post added at 07:05 PM ---------- Previous post was at 06:45 PM ----------
OK, 4.2 booted successfully
Thanks.
but phone does not connect to network.
IMEI seems to be lost (*#06# shows nothing for imei)
What do you think about restoring IMEI with dd-command from "somewhere"?
take a look here : http://forum.xda-developers.com/wiki/LG_Nexus_4/Partition_Layout
do you have baseband version unknown too ?
if yes, first I would try dd mmcblk0p1 (modem / radio.img) and only after that next step would be m9kefs1/mmcblk0p8 , m9kefs2/mmcblk0p9 = IMEI
this is only speculation, never tried that ...

no baseband too.
imei empty, not zero
I don't think dd mmcblk0p1 would be useful as it is only the radio.img.
You can find it in the stock image
The first step now is backupping the efs-partitions
do you mean directly writing IMEI to it?
I can try to copy the IMEI(or all partitions) from my brother's phone to mine
Thx
don't hurt to try dd modem partition first, maybe it's corrupted in some way ... why it's unknown ?
Hi,
I have a problem with my S5. After flashing a custom ROM I found out that my IMEI is null, and so the EFS is corrupted. I tried to restore it from backup only to find out that I have deleted the backup
What can I do now? I anything? Would restoring EFS from another S5 (with damaged mainboard) could be a solution?
Generally everything works except of phone modem, I have got IMEI written - is there maybe a method to set the IMEI without EFS or a method to create EFS? I already tried sam IMEI changers, but I found out that they only do this on the application level - apps will be able to read different IMEI for licensing, but phone still sees NULL IMEI.
You can't restore EFS from another S5 coz it'll brick your device.

Thanks - are you sure about this bricking device?
I already tried this numbers but it always says "No Network", The only instruction that I found was to use *#0011# and it goes into the Service Menu, but it doesn't look like that described. There is something called NVM restore, but it doesn't do anything with IMEI
I am gonnna post screenshots at evening.

Yes I'm sure about bricking. EFS partition on your phone is made for ONLY YOUR PHONE. This is sth like restoring TA Partition on xperia devices. When you flash ta from another xperia, you brick device
Tapatalked from SM-G900F
I read someone saying they had successfully restored a backed up EFS partition from an identical model S5 to another, and it worked
The problem I can see, is if the original gets blocked by the carrier, chances are so will the clone
Not sure about network issues having two identical devices on the same network at the same time, both making calls, might end up like an IP conflict
Pretty sure that transferring IMEI from one device to another is against the law too......
Sent from my rooted, debloated stocKK kn0x0 SM-G900F
Yes, I also know that is it against the law, but I have a complete phone with broker mainboard (so even the IMEI is written on the back), and I would like to use this opportunity to copy the IMEI from old (broken) mainboard to the new one. It even looks better than the situation when I have got and old case with written IMEI that doesn't correspond to the IMEI on the new mainboard.
The mainboard is broken that way, that there is short-circuit somewhere and the CPU is constantly using power and it get's really hot, so it use useless.
I am trying to flash EFS, let's see what is gonna to happen

1. Tried flashing EFS = nothing happened
2. Tried flashing EFS + Modem + ModemST1 + ModemST2 = nothing happened
3. Restored android to STOCK
I can't get into the service menu.
The only Service menu that I can get into is this one, but there isn't any fixing IMEI/NVRAM option
Code:
*#0011#
Menu > Back
Menu > keyInput "Q"
Menu > keyInput "0000"
Wait for few seconds

Hi,
you have 2 options
1. Use Samsung Kies which will repair you efs
2. Flash with Odin the official rom 5.0
If you install another efs, the data installed may be not work, even if it is same model. In S5, nothing to do with the IMEI
You can also root the phone and with adb commands, erase all the efs
you can also use Z3X tools
Hi,
Thanks - some new ideas
So if I understand you correctly, I have 3 options:
1. Use Samsung Kies which will repair you efs - how to repair EFS with Samsung Kies?
2. Flash with Odin the official rom 5.0 -> I tried flashing oryginal 4.4 and it didn't helped. Should flashing 5.0 help?
3. You can also root the phone and with adb commands, erase all the efs - What will erasing EFS will give me? Shouldn't I have EFS partition with some data?
you can also use Z3X tools -> ok... I am gonna figure this out, 'cause I don't know it yet

This does nothing on Galaxy A5!
attached 0011 code screen
Has anybody found the solution? Efs professional gives me error " device connection lost" while using Qualcomm nv tools on s5.
I have a D800 I'm working on for someone. They did a real number on it. It was semi-functional, but would randomly lose all screen function and had no service. Also had a persistent "ERROR" right above the home keys.
I performed a TOT reset to 20c, and everything seemed fine. I verified functionality and downloaded some apps using my google account, so once everything was fine I performed a standard Factory Reset via Volume - + Home/Home. Now, all hell has broken loose. It retained download mode - for a while - and I was able to flash all 3 available TOT's with semi-success. OS was bootable, sometimes, other times it was pure bootloop. Factory resets performed before and after TOT flashes. Confirmed MD5's, correct TOT+DLL combinations, etc etc. The phone is just pissed. Currently, the IMEI is now gone, but I know it. I wrote it down prior to doing anything the moment I got it. It also matches the IMEI on the inside of the back cover. I have confirmed this is not a frankenstien refurb - D800 on rear of mainboard / all panels / battery ribbon cables / etc. I lost download mode at one point, had fastboot. Couldn't get fastboot mode to work with my pc to repair it, so I manually put the phone into QHUSB 9008 mode, then 9006, then repaired fastboot so Download mode would work. Back to step one....Bootloops, hard freezes, random reboots, "ERROR" during RANDOM boots sometimes no ERROR, etc etc.... Something somewhere is just not meshing. I thought MAYBE the lack of an IMEI might be throwing the OS for a loop, so I tried the qualcomm and EFS Professional programs with no luck. The phone throws an error when trying to backup the memory, as well as write the HEX IMEI. I've tried various ports. Drivers are all current, and I've tried every available version of drivers I've been able to locate.
Anyone have any ideas? At all....? I'm familiar with most of the processes involved here, I just can't figure out how a full TOT reflash isn't wiping the issue...
Sorry, meant to put in Troubleshooting. Apologies!

I performed a TOT reset to 20c, and everything seemed fine. I verified functionality and downloaded some apps using my google account, so once everything was fine I performed a standard Factory Reset via Volume - + Home/Home. Now, all hell has broken loose. It retained download mode - for a while - and I was able to flash all 3 available TOT's with semi-success. OS was bootable, sometimes, other times it was pure bootloop. Factory resets performed before and after TOT flashes. Confirmed MD5's, correct TOT+DLL combinations, etc etc. The phone is just pissed. Currently, the IMEI is now gone, but I know it. I wrote it down prior to doing anything the moment I got it. It also matches the IMEI on the inside of the back cover. I have confirmed this is not a frankenstien refurb - D800 on rear of mainboard / all panels / battery ribbon cables / etc. I lost download mode at one point, had fastboot. Couldn't get fastboot mode to work with my pc to repair it, so I manually put the phone into QHUSB 9008 mode, then 9006, then repaired fastboot so Download mode would work. Back to step one....Bootloops, hard freezes, random reboots, "ERROR" during RANDOM boots sometimes no ERROR, etc etc.... Something somewhere is just not meshing. I thought MAYBE the lack of an IMEI might be throwing the OS for a loop, so I tried the qualcomm and EFS Professional programs with no luck. The phone throws an error when trying to backup the memory, as well as write the HEX IMEI. I've tried various ports. Drivers are all current, and I've tried every available version of drivers I've been able to locate.
Anyone have any ideas? At all....? I'm familiar with most of the processes involved here, I just can't figure out how a full TOT reflash isn't wiping the issue...

Hi everyone, i have a G2(D802) which i have used for 5 years. Yesterday, when i turn off the screen then try to turn on it didn't. I tried to reset with holding power button like 20-25 seconds. It stucked at LG logo. After many reset nothing happened. Then this morning i could was able to open my phone, so i thought it was a problem about software things, so i backuped everything and change my rom(i was using Lineage 14.1 ) to Resurrection Remix. But same thing happened, when i turn off the screen it has gone again. So i decided to install stock rom back. But this time when i used Flash Tool 2014 and appropriate KDZ, it stacked at 4%, after trying different cables, ports,windows 7/xp and programs (like LG Mobile Support Tool, LG Up) in Device Manager it seemed as : "qualcomm hs-usb qdloader 9006" and no recovery mode no download mode, when i google this problem i found it named with "qhsusb_bulk" and i found this article and successfully recover download mode. Now in Device Manager it seems as "LGE AndroidNet USB Serial Port".
TLDR: I can only open download mode, no recovery, it stacked LG logo, when i use Flash Tool 2014 or LG Mobile Support Tool with different KDZ/TOT it stacked at 4%. What should i do? What's wrong with my phone? I need your help urgently because i have no other phone. Thank you for reading.

hi there.. unfortunately LG did a mess in my opinion! After buying G2 and G Pad I will never buy LG again because of this..
anyway, assuming you're doing everything as described into the guides (like port COM 41, copy the right DLL file etc) there is one thing I would try in your situation: trying with a different PC, in particular a Windows 7 / XP one..
also I read that sometimes this issues was randomly gone after trying and trying and trying and trying and trying..! If available I would also try different KDZ firmware (but be sure it's for your model.. as long as it is it doesn't matter if it's JB, KK or LP)

Thank you for your suggestion, after several hundred attempts i successfully go back to stock rom(an Indian stock rom which i found it in storagecow link), but the problem is; when i turn off the screen, i can not open again, and it restarts and stuck at lg logo. After hundred times reset, phone started normally, then i flash a twrp recovery (with autorec) and go recovery. This time twrp said Unable to Mount System,Storage etc. so twrp shows internal storage: 0mb and all folders(data,sdcard,system etc.) empty. I mean define this problem is very hard and i think it is very rare problem. I'm not sure which part of the phone is the problem. I don't know is this a hardware problem or a software(like wrong partition or something like that) problem.

so ROM is flashed but no files are anywhere? Did the same happens when you browse the device with the windows command Prompt / Linux Terminal?
Yea anyway weird, maybe you can see if this tool has original partitions for your model: https://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 - please pay attention if you do it and backup the partitions you have atm before

I used this tool when my phone showed in Device Manager as : "qualcomm hs-usb qdloader 9006" and it worked, today when i opened my phone(after install stock rom again) i kept the screen always open. After 5 minutes, suddenly screen gone and stuck at lg logo. Now I think that the problem is definitely hardware. Because i did nothing and phone was connected with a cable to my pc. If the solution is to change a part(like the processor) inside the phone, I will write here what the problem part is. Thank you again.

pretty sure it's the mainboard, I saw it's the first part of the G2 that gives problem after a while

I found the problem part. It's the eMMC chip. I disassemblied the phone and heat the relevant chip (on my motherboard the chip named as Toshiba) with hot air gun. My phone worked properly for 1 minute, then gone again.

you know what: I think my device has the same issue, eMMC is damaged.. I'm not using the G2 as primary or secondary device anymore but from time to time I like to flash something and using it.. but it's almost one year that when stuff I have no error but when I boot the device and start using it I have random reboots.. but they are totally random and almost happen when installing one app, using a system app or something like that. it happens with both stock firmware both with custom ROMs.. basically I have to flash and using the device for a day and if I have less then two reboots in that period I go on..
I'm not an expert about hardware matters, do you mind linking me a video on YouTube about what have you done with the airgun? Also I tried to search for spare eMMC but I wasn't able to find any (some time ago) so the option would be to change the motherboard.. did you find something instead?

This is the video I get help with: https://www.youtube.com/watch?v=ft8V5yrQFic
this guy did this for g3 but doing for g2 also works. This is definitely a temporary solution. It works maybe just 1 minute (like me) or 1 hour if you are lucky maybe 1 month. Changing motherboard is primary solution but it is expensive and worthless. I think that is chronic problem for LG G series. There is no proper heat dissipation on the motherboard. They have just put thin metal plates. Maybe you can try after the heating process, just put a thermal pads the relevant chipsets. You can see from this video: https://www.youtube.com/watch?v=HMdvG6w7etU

I thought about applying something (couldn't imagine what however) on the internal back of the cover but not because of the issues I have but simply because the device get hot very soon! I'
But basically you are saying that this issue related to the eMMC is not because the chip is damaged but only for the temperature it reaches?

Yes, because of the eMMC chip is damaged. But the crux of the problem is processor heats and cause of no proper heat dissipation this damages other chipsets. Thermal pad solution must be done after chip replacement.
