Hi
"Disk Write Error " Mean You Have "Null" IMEI ,So QPST Can't Write data to partition

Only way is write NV1 and NV2 by dd command into mmcblk0p10 and mmcblk0p11

I have d800 with low signal after repair imei,actually only work "WCDMA".....Not Work "GSM"
So:
I need EFS or Full QCN readed by adb or efs professional or QPST
Also Can anyone tell me ,how can I switch "Nework " from gsm/wcdma/lte to another one ..? I mean I can't find this menu in phone but I can see this menu on another my g2(D801)

Unhappy EFS Premissions
trying to fix lg g2 imei.

i have followed all the steps mentioned in "http://forum.xda-developers.com/showthread.php?t=2701861"
and received the following : NvManager;;writeToPhone( excption thrown ) Unable to write NV_UE_IMEI" (Command failed, reason other than NVM was full).

So i gave up on that and tired your program EFS Professional > Qualcomm NV Tools > phone in pc software usb mode & usb debg is enabled (this was the only way to make the software see it & connected successfully > Secure Ops > checked MEID "wrote the MEID" > checked IMEI "wrote IMEI" > then clicked write.

Errors "Cannot Write: NV_MEID_I -- Error: NV_ERR_READ_ONLY_NV-ITEM" Cannot Write: NV_UE_IMEI_I -- Error: 4"

so i am assuming that because these values are write protected. how can i solve this, i have access to su adb shell using windows command line through ioroot25r1 adb tools.

The following was followed to root and install twrp recovery "http://forum.xda-developers.com/showthread.php?t=2633150"

Thanks,

I received the same error in QPST when trying to write. Got to about 20% then fails with that message. In EFS Pro I check the IMEI box and put in the correct IMEI and click write to phone. Says it's successful, but when I reboot the phone the IMEI hasn't changed. I didn't get any error message in EFS Pro, it just didn't actually write the IMEI. Ultra bummed!
