[LG Optimus L90] Floating Point:
In the past, when IMEI was stored in EFS partition, they were in plain text and could be hex-edited, but LG (and probably every OEM) changed this and now the IMEI seems to be encrypted in modemst, so the answer is no, at least I never heard about someone who could decrypt the partition data.

I know that there are some ways to recover the SIM1 IMEI, but the second remains blank, but this is something that cannot be discussed here in XDA (rules), so all I can talk about is the legit way to backup and recover from your backup.
[LG Optimus L90] ASPViTo:
well

Well over 2 days trying to put the 2 IMEI on the right place, hours of research, just now i found a video on youtube "https://www.youtube.com/watch?v=0fpaWmfroSo" the method works with EFS Professional Suite, and Qualcomm NV Tools, i just managed to put one IMEI on the place, but second still "0", confirmed with *#06# after a simple reboot. Funny is that i can still do calls with both sims. But if someone knows better to use this aplications, and can show us a way to edit second IMEI, will be worth a pizza and a beer !
[LG Optimus L90] Floating Point:
That what I was talking about.

But a method to recover the second SIM remains unknown.
[LG Optimus L90] root-1:
Whenever I try to flash the laf with fastboot (or use any fastboot command for that matter) it always says it failed, with an unknown remote command.
[LG Optimus L90] Floating Point:
You cant. LG removed fastboot commands.

With your phone rooted, you have to flash via adb or terminal with dd if=/storage/external_SD/laf.img of=/dev/block/platform/msm_sdcc.1/by-name/laf
[LG Optimus L90] root-1:
Alright, I'll try that. Only thing is, my phone is soft bricked... Can I do that purely using TWRP?

EDIT: I did end up flashing bootstack, and now I can access download mode. My phone has been wiped left right and center, I have attempted to restore it numerous times, flash the stock ROM, etc. But please, someone tell me. Is this the solution I have been looking for?

EDIT 2: Well, I was too desperate to unblock my phone, so I started the process already. I'm a little worried because the LG Mobile Support Tool didn't say I disconnected.

EDIT 3: YES! This actually worked when no one else on the internet was able to give me a solution! Thanks a lot! (not sarcastically)

I've had a couple issues with my L70 this past few weeks, one being that it would not let me update OTA and the other happened tonight when it kept loading with the systemui has stopped error message. I used this fix the first time, so I figured it would work again, although the guide I used the first time sucked because it told you to keep it in North Korea language which was stupid so I changed it anyway. Anywho, I had forgot how to flash the kdz so I had to google it again and clicked through a couple times to here. Thanks for the help! Worked again so far. Thank God, because I love this phone but I'm still wanting to upgrade soon but don't have the funds to do so immediately and needed a quick fix. {Sigh of relief}

Can't enter download mode.

So I accidentaly replaced aboot file and now my LG D405 is hard bricked. I cannot enter download. Tried Volume + and connecting USB but I only get Removable Disk in my computer which has folders image and verinfo in their. In LG Flash Tool I get a message that there is no connection between my LG and that program. I am so stupid :( please help me. How do I get into Software Upgrade Mode.
[LG Optimus L90] sjrsjr:
you have many step to do now.

First need to download 3 files.. DiskImagerev2 , HDDLLFsetup, Loader_410 this can be download when u search in XDA. I forgot the link

then you need to format the drive now which you can see in your PC, and update that with the loader_410 . this all details will be in the forum.

then take the backup of all the partition using EFS professional . bec when u flash the using KDZ file , u will lose the IMEI details. if you do with out backup then it is a great headache. One backup then flash using LG flash tool, this details are there in this thread.

then hope you will be back to normal

Hello,

I have a big problem. I cant connect my phone in software upgrade mode. I don't even see when is it turned on or off. I try to disconnect it from PC and then i hold Volume Up button and connect the USB cable but i cant see anything on my phone screen. It doesn't show anything but some icon that my battery is not inserted, when i connect my phone to USB with no battery. And when i try to use your method i always get the message that there is a problem with communication between my phone and PC. It suggests disconnecting phone and removing battery. I do so but nothing changes. Can you help me please.

SIM card not working

Hello,

I tried flashing Cyanogenmod 11 to my LG L90 D405n. I had some problems but i did flash it in the end, it loaded but one problem left - my SIM card is not working. It shows message: Emergency calls only. Then i decided that it could be the problem with that software I just flashed, so i flashed stock ROM using your posted method step by step. However the problem is still present, I can't use my SIM card. It also shows message: Current version is not available for user. Can't find matched cust for NT-code mcc/mnc[FFFFFF], subnet[12]. Could it be that flashing this new ROM damaged my phone antenna or is it just software that is blocking my connection? How can I fix this problem?

Thank you in advance.

Lady Vengeance has/had a LG-D415, not LG-D405. She had to send hers to get serviced. Unless you know someone with an Octopus Box, Otter Box, or something similar, I believe the service center is your only option. You may want to ask around at one of your local cell phone repair shops as well...

use those IMEI number and try it on a pc not phone.

I guess it isn't that important. Thank you all for trying, but I think that I will just have to wait to do anything too serious with rooting till I get another phone.

Please post screenshot or what exact error you are facing. Please check the data cable and device drivers are properly installed. Also check device manager after connecting phone in software upgrade mode, before starting process. Run "LGFlashTool2014.exe" as administrator. Also confirm is you phone shows any activity when process was started. Most important is do not connect phone before starting flash process.

LG's rct

Will this flash restore rct status to unroot, and give me back the warranty?
[LG Optimus L90] lfom:
First, try Kingroot from XDA thread, it should work to root any KitKat or Lollipop on L90.

In second place, if you want to SIM unlock your phone to use it with other carrier's SIM then it's a completely different subject. Bootloader unlocking is just to be able to change recovery (and system, consequently). To SIM unlock you must contact the original carrier and request it or buy an unlock somewhere (also possible online).
[LG Optimus L90] Davepr:
thank kind sir for reply i look that the Kingroot but i dont found nothing maybe i dont know where to star it is possible to link me the thread if that possible if not well i tried to look more and thk again

LG Flash Tool and the original firmware. Flash it back to stock and then re-root. If the device is detected, it should be able to flash it.

[LG Optimus L90] xanscorp:
...

Uninstall the current drivers

Use the LG Mobile United drivers found in this thread (Page 43 I think).

Install the drivers.

With the phone powered off, hold the volume up and down keys simultaneously and connect via USB to the comp/laptop to enter Download Mode. (I believe Qualcomm will still show, but as long as it detects the device, you should be good to flash).

Select the .kdz file from the Stock ROM to flash to the phone.

Wait until it is done...phone will automatically reboot into the basic ROM.

[LG Optimus L90] xanscorp:
Does it remain on the fastboot screen? If so you may be able to proceed through the rooting process in order to boot a ROM.
[LG Optimus L90] abc360:
Yes it stays in fastboot. But I can´t flash via fastboot, because the bootloader is locked.

But in fastboot my computer recognize this smarthone.
[LG Optimus L90] xanscorp:
I meant in fastboot. (On a side note, if it went to fastboot to begin with, your bootloader was/is unlocked.)

Also, can you get into any recovery? Booting into recovery is a different key combination than download mode.

Rooting allows you to remove it. You'd have to remove them yourself... unless you flash a custom ROM too.
