abc360, are you using t-mo's 415, ora different l90?
[LG Optimus L90] abc360:
It´s a LG D405 L90.

[LG Optimus L90] lfom:
What is your phone model? If it's not D415 then you have a chance using one of the "hard brick unbrick" tutorials. Have you tried them? Be prepared, you must disassemble the phone and be careful with some probe tips, but it's the only known way if it's completely dead. If your computer sees a Qualcomm device then you can try other tutorials that explain how to rewrite the proper partitions to fix your phone. Good luck.

Any solution for the lost imei??
[LG Optimus L90] phoenixsun28:
Can't download kdz file

Hello all. I am having trouble downloading the kdz file for my phone. I have the LG-D415, and upon entering my IMEI through the resource provided in the OP, it tells me I need: TMO/T-MOBILE(USA) V20f for LG L90. After going through the captcha, I am then directed to a page that tries through numerous methods to try to get the user to download all kinds of malware (after having gone through the process at least 4 times now, each time was a different solicitation of a different software). After clicking away from the malicious solicitations, and then skipping the ad, I am eventually re-directed to what seems to me to be a legitimate URL: http ://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW68EQV972FNA6X7967B42K/D41520f_00_0110.kdz (I inserted a space after http so as to allow it to display). However, the page either loads blank or can't be displayed (attempted in multiple browsers with no adblocking).

Pretty frustrating. Any help would be greatly appreciated.

Thanks!

Here is the link for T-Mobile (D41520B): https://www.androidfilehost.com/?fid=24052804347759872
[LG Optimus L90] phoenixsun28:
Hi Tejas, and thanks for the quick reply...

I'm just curious to know what is the difference in the number-letter combination (e.g. 20B) between the different models?

I only ask, because the utility linked in the OP directed me to download the kdz for the 20F, but the link you provided is for the 20B. Meanwhile, the sticker in the phone says "S/W: V10c".

I'm not familiar with the difference, and am just slightly apprehensive about proceeding with what seems like some very non-specific identifiers.

Also, just to include all specific info, my model is "LG-D415" with no additional characters, as per the LG sticker inside the phone.

Should I be worried at all about the discrepancies?

Thanks,

Phoenix
[LG Optimus L90] Tejas tedi:
That's the software version number 20B is older one and 20f is latest.

I only got the link of the older version so I shared it for you

By the way main thing you Should see is the model number and the SW version doesn't matter..So you can flash it[emoji2]
[LG Optimus L90] phoenixsun28:
I understand, Tejas. Thank you, that is very helpful info...

I'm now prepared to go ahead with the flash, but after going through the OP, it says that a file: B2CAppSetup.zip was to be attached somewhere to be downloaded, but in looking through the attachments, the only one I found was the LG2014FlashTool.zip. Did I miss the link, or perhaps do you have one I could use?

Thanks again,

Phoenix
[LG Optimus L90] Tejas tedi:
That one is not compulsory

The drivers of LG phone will be installed automatically when you connect your device(if not installed means download from other site by searching drivers for LG phone) and extract the rar file to get the kdz ..
[LG Optimus L90] phoenixsun28:
Thanks for the help, Tejas. I found the drivers on LG's support page, and I was able to successfully flash the phone with the file you provided.

I would just like to ask if I should still expect to receive updates from Android with this current version, because as of yet, I've yet to receive any prompts, and I know that T-Mobile's latest update was just within the last month. I actually prefer not to ever get OS updates, but just figured I'd ask you while I have your attention.

Thanks again,

Phoenix
[LG Optimus L90] phoenixsun28:
Nvm, Tejas. I already got the updates, and went through and just did them all, as I had to update like 5 or 6 times, each time increasing a letter. Maybe that info will help someone else in the future...
[LG Optimus L90] phidias81:
Hello, I have a D410 v20c, rooted and original bootloader (not unlocked)

As far as I understand I don't have to unroot before starting the procedure, right?

Also I read that the D410 v20c version gives problem if I try to install custom ROMs, that's why I want to downgrade. Can I still follow the procedure described here also for D410 v20c, or am I going to have problems? Thank you
[LG Optimus L90] Cueza_89:
Good morning,

Just followed the procedure on LG L90 d405n and everything goes fine until the end: using hardware method to short the mainbord and it has been recognized as Qualcomm, then follow the steps but when everything finish and it boot up it gives "security error" so I flash offline the right .kdz, everything go fine but when it boot up it stucks on boot logo forever. The device is unrooted what can I do now ? The phone boot up, it shows recovery (already done Hard reset) and goes in download mode pressing volume up while connecting to USB.

Let me know what You think will work for my L90.

Tks
[LG Optimus L90] AcuraKidd:
your guide doesn't work for my phone. I have the T-Mobile version L90 D415. I installed Lineage OS 14.1 but lost root and TWRP

I tried all the one-click root methods and nothing works because it gets stuck at the point where it says Looking for LG Serial port...

this flash method doesn't work either, gets stuck at the last part after I put the phone into Download mode and connect, the computer doesn't recognize it, and neither does the flash program.

Please help

Full Wipe

Attempted to reload my D415 after a failed install of the Google Dialer. It kept all the software in place after following the instructions. Things are still broken.

Is there a way to do a full wipe and back to factory?
[LG Optimus L90] hamedbb:
Has anyone tried this with optimus L9 p768 ?

I would like to re-lock my bootloader please .
[LG Optimus L90] babcocca:
Its OK now

I deleted every file I could find relating to the dialer and its services. I reflashed. All is working now. Dont install the Google Dialer.
[LG Optimus L90] gdjindal:
Sorry buddy

It's not possible to relock bootloader on LG L9.
[LG Optimus L90] SubliemeSiem:
This might come in handy for some people too:

I used this method many times to go back to stock, but the last time I tried this my device got into a bootloop. I actually fixed this by shutting down the phone, starting the phone with the power and volume down button pressed, releasing those buttons when the LG logo shows up and immediately pressing them again, then choose to perform a factory reset. After the factory reset the phone booted like I expected it to. Might not work for everyone, but is definitely worth a try before you try to flash the KDZ file again.

It only happens when you enter wrong IMEI number, so enter IMEI number correctly, open website on pc, not on mobile.
[LG Optimus L90] xantanion:
Well i entered the correct imei x4 on both pc and mobile, then roommates computer and nothing. So it's not just wrong imei causing it.
[LG Optimus L90] gdjindal:
what L90 model you are using, then only thing i can do for is, ask other users to generate the link for you.

The phone does not turn on at all and I tried the volume down and up they dont work

So, need some help here, Downloaded the KDZ, LG Drivers are right but it never goes past the "Phone is disconnected from PC" message. I'm downloading another KDZ file see if that helps but so far I'm stuck.

UPDATE #1: New KDZ did not fix issue. Starting to run out of options.

WHAT I'VE DONE SO FAR: Rooted and installed TWRP. Tried to install CM11, Had the 128MB issue everyone else was having. Did a factory reset via LG Button combo. Rebooted. It booted back in to TWRP. Rebooted that it booted into CM11. Tried to go to stock. Now having KDZ flashing issues.
[LG Optimus L90] gdjindal:
Hi Angel,

Don't panic, I also faced this issue many times while flashing KDZ. Just go through following steps :-

After installing device drivers, unplug phone and reboot pc. After reboot don't connect phone until wizard says to connects the device.

After connecting phone in software upgrade mode open device manager and confirm 2 new devices as shown in screenshot below

If still it says device not connected, just unplug and plug it again while phone is in software upgrade mode and press retry button.

Hope these steps will solve your problem :good:
[LG Optimus L90] ArkAngel_X:
Don't see an image but this is all that's in Device Manager. Not sure if I installed drivers correctly.
[LG Optimus L90] ArkAngel_X:
ALL IS WELL!

Here's what I did wrong: When I originally rooted and ROM'd I left it in fastboot mode just in case i needed to flash something incase something went astray, i dun goofed and freaked out when nothing would work so i consulted this guide right here and realised thatyou can only have Software Download mode or Fastboot mode. not both. Flashed the backup laf.img i downloaded from Lady V and wham-bam-thank-you-maam it worked. :DDD

Can someone share a kdz for d410

First of all I got a normal working phone Lg L90 d410 rooted xposed no bootloader v10b

I tried to input my imei and got a link but the version that is available for download is sadly 10b still.

What I need is the 10c or a for aboot purposes.

anyway is it safe to just use v10c aboot file for my v10b?

Thanks in advance
[LG Optimus L90] wojtek267:
What you are downloading is a kdz file. It will change your system to v10b but it has nothing to do with bootloader at therefore aboot at this stage. You can flash it safely
[LG Optimus L90] kylesean:
You mean I can safely flash the v10c aboot on my v10b system?
[LG Optimus L90] gdjindal:
Hello kylesean,

Which variant of L90 you are using, if aboot.bin file is not listed for your device then please don't use any other aboot.bin it could brick your device.
[LG Optimus L90] kylesean:
Hi gdJindal,

L90 D410 V10b.

Ok thanks for the advice. I was about to use v10c aboot file. So does this mean that my model's bootloader cannot be unlocked? Or can I just borrow an IMEI with v10c link hehe :)

[LG Optimus L90] ryder151:
hi, installed my stock firmware on my lg l90 and when i try to unlock it or touch the screen it touches somewhere but not there where i want, but when i install a custom rom called cyanogenmod everything is alright, why is that happening?:confused:
[LG Optimus L90] kylesean:
Is flashing a wrong kdz will brick my phone? Cause I'll try to flash a kdz from the lgl90 ultimatethread. My imei returns v10b only.
[LG Optimus L90] SubliemeSiem:
Open the hidden menu using 3845#*4XX#, where XX is your model number. So if you have a D405n, like I do, you'd enter 3845#*405#. Here choose "HW Device Test" and then first run "Touch Test" and afterward run the option to update the firmware or something like that, which can be found in the same menu (HW Device Test).

The lg site referenced in the tutorial always gives you the right kdz, since it's based on IMEI. If that site gives you V10b, then apparently that's the software that comes with your device.
[LG Optimus L90] kylesean:
We are forever stuck in a locked bootloader...

Thanks for answering.
[LG Optimus L90] ryder151:
I will try to do it, but when i download stock firmware from lg-firmware-rom.com , flash it, then when i go to settings it says that my phone model is D410, but mine is D405N, so why?

---------- Post added at 12:23 PM ---------- Previous post was at 11:24 AM ----------

Tried that, didnt work, i dont know what the hell happened to this phone bought it yesterday, i said to myself i want custom rom, installed it, everything was fine, just some problems, so i wanted to go back to stock, and this is what happened... System is running perfectly but the screen is sometimes working good, sometimes don't.. I dont know what to do, in custom rom screen works fine :confused:
[LG Optimus L90] SubliemeSiem:
Not sure.. Are you sure you used the correct imei? You can check by typing *#06# in the dialer. Otherwise I wouldn' t know. In this case it might be a good idea to contact lg support if you keep getting the wrong model in your settings.
[LG Optimus L90] ryder151:
Yes i typed it correctly, one time i needed to reinstall stock firmware, and it worked perfectly, but this time its not, you sure you dont know why?

---------- Post added at 12:40 PM ---------- Previous post was at 12:30 PM ----------

Ok, i checked now my model number is correct screen is working fine for now, i dont think it will work fine all time, because it works fine for 5-10 minutes, then goes back to random touches when i press.

Thank you! It's working fine now! :good:

Try here

http://lg-firmware-rom.com

You don't need to "read phone information" just flash.

Make sure you have the right

Kdz

And it'll get an error with the lg server but it still works because it doesn't download the files from the internet so it doesn't need to connect to the servers.
