Do you have land-line phone service? I'm thinking of getting one from best buy that costs about $300. It does not use the phone line, per se. It just uses the wiring as the antenna and boosts 4g. Don't remember the name. . .
[Verizon Galaxy Note 3 Q&A, Help & Troubleshooting] scott_65:
I don't have the service, but the old house I bought does still have the wires in it. Same thing I suppose, unless it uses the voltage thats in the wires... Good idea, I'll look into it as well. Thanks!

Original guide created by ChikushodoF for the LG G3. Use at your own risk!

The LG L90 does have fastboot, but it's hiding "behind" LG Download mode. The steps to access it are as follows:

Note: This assumes you've already rooted manually or with Towelroot and know what adb/fastboot is.

First, backup your LG Download mode (laf) with this code, so you can use LG Flash if necessary.

adb shell

su

dd if=/dev/block/platform/msm_sdcc.1/by-name/laf of=/sdcard/laf.img.

Run the following code to zero out laf:

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf

adb reboot

For whatever reason, you won't be able to access fastboot via "reboot to bootloader" like most phones, so you've got to do a key combo:

Power Off

Unplug USB

Hold Volume Up

Plug in USB

There you go, access to fastboot. I have attached a zip containing fastboot drivers for Windows users.

That would be on LG as they're the ones who removed the commands from fastboot. Without LG's sources, no one can do anything about this but LG...
[LG Optimus L90] professaWuKong:
otherwise unlocking the boot loader and doing fastboot recovery stuff. what else do u need it for.

cuz apparently the bootloader is already unlocked

i just use flashify and flshed twrp and went from there

i used 1 click root for lg to root my phone.

i would advise d415 users to avoid editing the laf. cuz if u dont need it and it only would cause issue. stay away from the fastboot . but i could be wrong.

Hi [MENTION=5412690]LaDY Vengeance[/MENTION],

I have a lg l90 d415 rooted with super su. When i boot into fastboot or what seems as it where it says "fastboot processing commands"-is that right?-and i type in "fastboot oem unlock" on my cmd window, it says FAILED (remote: unknown command) finished. total time: 0.004s. FYI, i already have twrp 3.0.2 flashed img with flashify and it runs. Do i still even need to unlock my bootloader? Also can someone plz provide me a link to cm 13(or latest) and gapps that goes with it. Thanks a ton in advance.

I'm using the file you uploaded too

Please help

Thanks!
[LG Optimus L90] shinobisoft:
You don't need to do any of this for the D415. You've already been advised of this fact, in several threads...

Edit:

My bad, didn't realize you were trying to restore your lag partition. Is 'laf.IMG' in the same folder as the fastboot executable? If not, move it there or include the full path to the laf.IMG you wish to flash.
[LG Optimus L90] irfan61802:
Thanks sorry for my clumsiness. However, i already tried putting it in the same folder and when u say path do u men add the laf to it because i already added the whole folder to the path. Thanks Edit: Actually none of the commands i type work in fastboot. It keeps saying remote: unknown command. Please help. Thanks
[LG Optimus L90] shinobisoft:
I have a better solution...

Copy your "laf.img" to your sdcard. Internal or external, just remember where. Visit this thread and download and install my LG L90 Utilities app. Once installed, go to "Fastboot Manager", I think, lol. In the upper right hand corner is the menu button. Press it and select the only item "Choose restore image". This will open a file browser that will allow you to browse your device for the laf.img file you put on your sdcard. The file browser initially starts in internal storage. The first item in the file browser is to switch to external storage, the reverse if browsing external storage. Once your laf.img is found and selected press the button at the bottom of the app to restore the partition. Since you are trying to restore your laf partition, when the Fastboot Manager page initially opens, it should show Fastboot in green with a green check mark in front of it. After choosing your restore image, and if successfully restored, Fastboot should turn red and Software Upgrade should turn green. Your done. It sounds more complicated than it is.
[LG Optimus L90] irfan61802:
How do u tell when and if it is actually doing the work. After i click select, it just closes the window and still show fastboot with a green checkmark. And when i press the bottom button "toggle" is shows up with a blank window saying warning with an ok button. When i press it nothing happens. BTW i know i used the right laf because it is the one [MENTION=5412690]LaDY Vengeance[/MENTION] provided. Edit: If this doesn't work or even if it does, i might not have downloaded the correct fastboot drivers hence none of the commands. Can you plz give me instructions to do that too thanks.

Thanks for your help!
[LG Optimus L90] lung1:
hi!

I'm stuck with no ROM and no download mode. I have the laf.img because I backup it, but I can't flash anything. I fact any command that I type results in: FAILED (remote: unknown command)

Do I have a hardbrick? Can I do something?
[LG Optimus L90] Snorp09:
I'm in the same situation. Except... I don't have my LAF.img anymore. (I'm sure I backed it up, but I have no clue were I put it. I suspect I lost it in a hard drive failure I had.)

So... yeah... is this a hard brick? Is my poor phone bricked? (Lucky, I'd never do this on my main phone, so I'm still good phone wise.)

EDIT: Oh yeah, I forgot to mention, the download link for laf.img has malware.

For last, the phone is recognized by the pc because the command fastboot devices shows me the phone and when i enter a command like fastboot flash recovery recovery.img i only get FAILED (remote: unknow command) but, the phone shows the command in the screen. Is my phone dead? is there anything i can do to unbrick it?

But using some device info apps, it still shows as unknown. What do you think?

I'm afraid I can't help you with that one. My only suggestion is a factory reset. You'll need to restore your laf partition first. I have a LG L90 D415 that has hardware keys. The only other thing I can think of is installing Xposed Framework and the GravityBox [KK] module so you can reenable your navigation bar.

[LG Optimus L90] shinobisoft:
Did you do all of the following:

You installed and opened Xposed Installer. Then went to the Framework page and pressed the "Install/Update" button.

Then went to the Download page in Xposed installer and downloaded and installed GravityBox[KK].

Then opened the Modules page and placed a checkmark ( enabled ) the GravityBox [KK] module.

Then rebooted device and opened GravityBox [KK] and selected the "Navigation Bar Tweaks" option and then enabled the "Master Switch" in General? And enabled the "Enable navigation bar" checkbox too? Then rebooted device one more time?​

---------- Post added at 05:04 PM ---------- Previous post was at 05:01 PM ----------

If you're missing that many apps, then I'd highly suggest a factory reset ( Hard reset ).
[LG Optimus L90] eta82:
Yes exactly as you described.

But etedy lose unlockbootloader so?
[LG Optimus L90] shinobisoft:
You can always unlock the bootloader again. Do you happen to have a recent CWM/TWRP/Philz-Touch( any recovery ) backup? If so, why not restore it?
[LG Optimus L90] eta82:
How to unlock the bootloader??

I do not have CWM / TWRP any backup. I have a stock recovery :(
[LG Optimus L90] shinobisoft:
Not sure how to unlock your bootloader. Search your devices forum. Since you don't have a backup your only option is a Hard Reset. This will completely restore your device. I'm not sure what key combos are needed for a hard reset for your device. You may be able to do it thru Settings->Backup & reset and select the "Factory data reset" option.
[LG Optimus L90] eta82:

I wonder which is better, fastboot or download mode?

I wish they could be separated, so its not one or the other
[LG Optimus L90] Failbringer60:
I thought the whole point of deleting the laf was to get into fastboot mode to unlock your bootloader, then after its unlocked you should be able to flash laf back to get download mode back and not lose the unlock of the bootloader correct?
[LG Optimus L90] shinobisoft:
That would be correct. The advantage to fastboot mode over SW upgrade mode, in my opinion, is with fastboot you'll never need to mess with a KDZ, which makes this device practically unbrickable.. XDA is riddled with threads about KDZ errors. It's not just the KDZs that are the issue, it's also LG's crappy software.
[LG Optimus L90] LaDY Vengeance:
How did you do it? That could be useful for someone that experiences the same thing! [emoji4]
[LG Optimus L90] aSuperSaiyanG0D:
He just downloaded a fresh kdz since his old one was possibly corrupted ?
[LG Optimus L90] shinobisoft:
On the L9 fastboot is built-in with u-boot. I'm guessing it's part of the bootloader for the L90 as well. I believe the 'laf' partition contains the files needed for a complete restore to stock via Factory Reset.
[LG Optimus L90] Ilxaot:
My KDZ wasn't a completed download LOL.

used is 128.0K so i`m safe?
[LG Optimus L90] shinobisoft:
According to your screen shot the laf partition was NOT backed up. The laf.img on your sdcard should be 22 MB. To use the "dd" command you must first grant root access to the shell by typing "su" without the quotes. You will get prompted on the device if root permissions haven't previously granted to the shell. Then do the "dd" command. All you are doing is making a block for block copy of your laf partition. If you're trying to enable fastboot you'll need to zero out the partition AFTER making a backup.

To simplify things, why not use the script I created for this? Look for "[SCRIPT] LG Optimus L90 Utilities" in the General Section of the L90 forums.

[LG Optimus L90] Edvinoske:
I didn`t do anything, just tried the first command and It`s like this.

I`m running cm11 so maybe by unlocking bootloader I unlocked fastboot?

I`m doing this so it`s harder for me to brick the device as I understood from earlier posts.

Thanks for reply.
[LG Optimus L90] shinobisoft:
No. Unlocking the bootloader DOES NOT enable fastboot. To unlock/enable fastboot mode the laf partition MUST be zero'ed out.

[LG Optimus L90] shinobisoft:
You have to write the laf backup back to the device. You can't have both. Its either fastboot or S/W Upgrade mode.

Swap the 'if=' and 'of=' parameter values in the dd command from the steps you followed to enable fastboot.

EDIT:

Bootloader is fastboot mode. Directions to get to bootloader/fastboot mode are in the OPs directions . You don't have to wipe the partition every time. Just once.

I believe its power off device then push and hold Volume down and attach USB cable to phone. Phone will boot to fastboot.

If you want or need Software Upgrade mode then you will need to restore the laf partition.
[LG Optimus L90] simpson5774:
Alrite, need some help.

I attempted to do the guide to put my D415 into fastboot mode, ive spent practically the whole day searching these forms and online to get this thing unlocked and junk to get CM11 or another rom onto this device. I mean I am not a guru at this stuff but I usually can read a guide and execute. I did this to my nexus 5 but apparently the D415 is T-mobiles middle finger to enthusiasts.

Anyways I did this guide more than once before I Was able to get my phone into what appears to be download mode but I need some guidance to figure out what I am looking at and what It means.

so I do the guide, to attempt to gert into fastboot mode and do the oem-unlock command I turn off the phone, unplug my phone from usb, then re-plug it in while holding the sound button up, I get into what says up top:

"download mode"

[150] fastboot_init()

[250] usb init ept @ bla bla

[270] udc_start

[380] --reset--

[380] --portchange--

[540] --reset--

[540] --portchange--

(and if i unplug my usb I will get a new number, and a continuation of reset and portchange. I don't get the "Fastboot processing commands" or any other messages, and I can't run the fastboot command on my pc, it says "waiting for device" and does nothing.

I don't want to sound like a nub in my question, but I feel like one because I can't seem to find the answer to this myself.
