Hi
I mistakenly restored a QCN file yesterday via QPST software on my phone. But when the phone was rebooted, IMEI and bassband were removed!
After doing everything to restore the original backup, I get a corrupted NV data error!
Anyone have any idea to solve this problem! Thankful
you can try this in twrp terminal
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2
and reboot your phone
do this at your own risk fixxed it for me on my pocophone but i never got the imeis back in btw i had em back in the phone but never got a signal sim got recognized but no signal

I've done this before and IMEI is zero. But it didn't matter to me as it did before.
There are efs version and imei unknown right now and no operator network connection possible!

So a customer brought in a Tab3 to me with this horrible McAfee Livesafe software on it that had locked it.
it is asking for a pin, he is adamant that he never set this up.
you can't click "forgot pin" because it needs a data connection and I can't activate the data connection because the device is locked.
I have successfully flashed the device in Odin but it just starts up and lands back at the McAfee locked screen
Is there anyway around this ?
the customers data is not important and can be wiped.

I'm not sure I understand you, i have flashed it already if thats what you mean
Flashing in Odin does not wipe user data. You need to boot into recovery and perform a factory reset to wipe the user data.

Are you certain the device isn't stolen?
okay, if you can reflash the device with a good custom recovery, meaning being able to run adb shell as root for push/pull
and parted is built into the recovery, AND losing data is truly not an issue,
first try twrp for it's format data function which will wipe ALL of userdata. if nogo
try philz (more options) while in recovery connect via adb shell # and run
parted /dev/block/mmcblk0 --- wait for the prompt...
(parted)
then enter
print all
copy that output for reference, at the beginning of each line the number corresponds to the mmcblk0p##
note the block ## for cache and run
dd if=/dev/zero of=/dev/block/mmcblk0p[cache's block##]
then
reboot recovery
have a stock rom ready to flash or push to device's external card.
in philz format data and internal sdcard, flash rom and reboot.
if you still hit the lockout, something's living probably in /efs or /param.
param block on tab3 can be dumped or pulled via adb
via adb shell
dd if=/dev/block/mmcblk0p[param block##] of=/storage/extSdCard ---> your actual mount point may vary, adb pull off device
via adb [as root]
adb pull /dev/block/mmcblk0p[param block##] param.bin
param extraction and repackaging [works on tab3 10, note 10]
tar xf param.bin
look through it or just pull param from another known clean and correct model and replace
if there is something skunky and you can remove it, then to repack param.bin --make sure to move old param.bin out of $PWD
tar cf - `ls | sort -t.` > param.bin
then push back to device and reflash/write
dd if=/[$PWD]/param.bin of=/dev/block/mmcblk0p[param block##]
reboot

edit - remember to reformat cache through recovery
I had TWRP 2.7.1 and Android 5.1 (adriano's AOSP rom), and then I did volume up + power button to go into the recovery, did my thing (I don't even remember what it was), true is, after that it only reboot's to TWRP, so way I can go into system.
I've wiped/formated everything I could, but it always goes to TWRP no matter what.
I've tried to go back to stock through LG Tool, but I'm having connection to server fail issues.
http://forum.xda-developers.com/showthread.php?t=2451696
On step two I have "no space left on device". Not sure if it's an error or not, true is, it does nothing. Also, I don't have USB storage access, my drivers have probably some other problem (strangely adb it's ok as mentioned).
I'm trying to back to stock, but I can't go into download mode because it goes straight to TWRP.

Any help please? Completely desperate!
Do you have an SD card in your device? When I was stuck on TWRP on another device, removing the SD card solved the problem then.

You will need an SD card to install a new ROM. Otherwise since you are on TWRP 2.7.x, you cannot add files to the tablet inside TWRP.

That was not a problem because I already had a custom ROM on the internal storage.
The problem was no matter how many times I wiped/formatted everything, and applied the custom ROM, it was always booting to TWRP.
i had the same problem
i was stuck on recovery
i fixed it by enter this in terminal comand
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
enter then
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
i did reboot recovery and then flashed a rom and it worked

I tried something like that, not sure if it was exactly that though.
Anyway I managed to revert back to stock 4.4.2 through the LG tool, which solved my problem, thanks anyway!

Maybe you could fix this by using TWRP terminal commands, and enter the following:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
Click to expand...

Reboot.
Good luck
Thank you for your reply!
tried to do it but after
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota i got error :
can't open /dev/block/platform/msm_sdcc.1/by-name/fota no such file or directory
any ideas?
Checked in file manager - under /dev/block/platform i have only /f9824900.sdhci and not /msm_sdcc.1 . Also under mount - system partition is not checked, when I check it and reboot it is still get unchecked. Any advise?

Copy Stock Rom (older release is better)to the phone's root, then Wipe Dalvik/Cache. Return to Stock recovery and try to flash it, maybe it will fix the boot issue.

Already tried 13s official. Also tried to restore from system backup... still twrp bootloops...
Hello,
I was disabling journaling on my device's partitions then after rebooting from the TWRP I found a very slow startup. After that I thought it a bootloop. So I installed the previous ROM which was DevBase, followed by many as Alexis and others they were all giving the same a bootloop or at least what I thought it was.
So I flashed a stock firmware but the true issue started after this the IMEI is invalid and showing as null.
I found an EFS backup inside of .backup/efs/efs_bqckup.img.tar inside of the OTG folder together with recent.img something like that.
I tried to Gunzip to restore on the /sda3 partition didn't work nor direct dd command worked for the .img
How can I restore my EFS or repair the IMEI in a legal way note that I've everything for the phone including it's IMEI.
I`ve lost efs. Can`t get it back. the phone stuck at bootloop. tried to restore using adb command. it seems that is flashes back the modemst1 modemst2 but after a reboot they are lost again.
I also have qcn backup. but I`m not able to do anything with it.
If it happened spontaneously, then my bet is on a hardware fault.
If it is the result of something you did, then please describe as much as possible.
I did it and then the phone stuck at bootloop. I used TWRP for erasing EFS. Nothing helps like flashing different version of factory images. except the android 11. for the first boot the phone starts with no imei no wifi no mac address then if I reboot for the second time after flashing android 11. it bootloops again
Sounds like you've got a backup - if so, it should be possible to restore.
I haven't been in that situation myself, but I would try fastboot, something like described here:
How to Backup and Restore EFS Partition on any Android device
EFS is a partition on your Android device that stores all the important data associated with your phone. For instance, these data include the IMEI number,
www.getdroidtips.com
But this is for different phone, so you may have to change partition names.
I do not have my original efs but got it from another pixel 2 xl. I thought it should work but it didn`t. it flashes efs modemst1 modemst2 fsg fsc. but after reboot those files disappear
I do not know if installing the stock rom with the Deuce tools from here helps
