[Q] Can we use LG provided files to unbrick L90 - LG Optimus L90

I came across this link in one of the posts. So can we use these files (rom + kernel) to flash your phone back to stock. will it help unbrick any bricked phones?

Those are the sources for the L90, D415 variants. They must be built first then possibly flashed via recovery. If you don't have access to your recovery or fastboot then KDZ flash or warranty claim are your only choices.

You won't be able to flash any kernel or ROM without ensuring that your bootloader is unlocked first. The stock boot.img ( which contains the kernel ) is a signed image signed by LG's own key which we don't have access to. The bootloader checks the signature of the boot.img before booting. If the signature doesn't match you'll end up with either LG Security Error or a soft bricked device.

So basically I bought the wrong phone?
This is not a customizable device? Should I sell it and get a different model? What is this KDZ thing they talk about in the other forum?
Can you unlock it?

We call this process unlocking, which is needed before rooting. After rooting, u can still customize it more freely.
ps One special case (not for u Americans). In my home city, unlocking is not needed for any devices, and we can root directly

I have root, used an laf multitool to pull and backup the laf.IMG in order to access fastboot mode. I've unlocked my bootloader and restored download mode. I have TWRP 2.8, can i use a kernel like the one mentioned in the OP? Or should i just keep looking for custom l90
kernels? I'm a noob and I couldn't help but ask

Currently, there's only one custom kernel in development ( here at XDA anyway ). Whenever you flash a custom ROM you are also getting another kernel. As stated, the kernel is part of the boot.img. The boot.img, at a minimum, is a combination of the RAM file system + kernel.
Man, this phone is pretty bad a$$ with the current development. Search for sound mods, etc. My phone is super loud!!!

There's currently no custom kernels available.
Only Custom ROM with their kernels available.

This is kind of a deal breaker for me, that and the broken rar archive. BUT when it starts working I would like to use your ROM because I love stock roms with minor modifications and debloat. Did you use this xposed framework? http://forum.xda-developers.com/showthread.php?t=3034811
When I flashed the completely stock version, it broke, no data/wifi/bluetooth, and everything crashed. I think it was because I wiped first and since this is an OTA I shouldn't have done that, but now I am worried about trying again, since I just got my phone back up and running. I must say thanks for that, because flashing using TWRP and your ROM gave me TWRP back, so I was able to downgrade back to 410c stock from your ROM. I'll wait for the radio problem to be fixed before I try again.

You can flash safely with TWRP. Go ahead and upgrade to Stock Lollipop via KDZ then you can try flashing one of brossovitch's ROM. It worked for me. Just follow this http://forum.xda-developers.com/showthread.php?t=3088131 guide if you get broken IMEI or/and Baseband. It will help you get it back as well as get Lollipop on you phone.
Good luck!
So if I read that right, you have to flash the Stock 5.0.2 using TWRP, then flash the Stock 4.4.2 using the LG Flash Tool, then flash the Stock 5.0.2 using the LG Flash Tool, then root then unlock bootloader (is that necessary with the D415? I never did that before) and then use Rashr to flash TWRP and then flash brossovitch's LollipOptimus ROM, just to get the IMEI/Baseband to work? Seems like a lot of hurdles. Why not just flash the 5.0.2 KDZ and then root and flash TWRP possibly with or without bootloader unlocking and then flash the LollipOptimus ROM, or even just flashing it like an OTA from TWRP? Will the LG Official OTA break the IMEI/Baseband?
And has anyone tried the linked Xposed framework?
Thanks for your help!

No, that is if you had a failed flashed and did not have Stock Download mode which you lose if you unlock the boot loader (which is technically unlocked). Unlocking bootloader is optional, I should put that.
If you have unlocked boot loader then you need to either flash the lag.img or bross's stock ROM with laf.img in it.

I'm going to try xposed again.
I'm also going to upload the partitions needed to make the bseband work.. There's a way to be easily flash them to go to either.
Stock lollipop is just different. And the custom roms are based on KK. so we gotta be able to go back if we want..
We can.
With L90 utilities you can flash your laf partition or toggle it between fastboot mode & s/w Upgrade (firmware download) mode.
From there you can use adb to flash the proper partitions.
IE:"fastboot flash radio modem.bin"
Which would likely work..

Just restored your latest nandroid and is WORKING GREAT SO FAR !!! Just one thing , how did you guys get rid of the annoying t-mobile voicemail notification ?
Am new to TWRP so excuse me for asking, but since I restored back to 4.4.2 my phone is better than it was before. I would like to upgrade, but I'd like to be able to revert back to 4.4.2 if I have a bad experience. I backed up my phone with TWRP, can I flash the kdz with the LG tool, and then root and get back to TWRP and flash the ROM to make the radio work, and then back up the 5.0.2 ROM and switch between the two?

Follow this http://forum.xda-developers.com/showthread.php?t=3088131 guide If you have Downlode Mode, skip step 1 and since you are on KK, skip step 3.
Sent from my LollipOptimus™
Since I cannot reply directly to the main thread or the How to fix IMEI/Baseband Unknown Issue (D415) thread, I will ask here.
I am currently running the KitKat stock and rooted, with the original laf.img and TWRP recovery, de-odexed system, and several unwanted stock apps uninstalled.
From my arrangement, to upgrade, I can go to download mode using Vol + and Plug USB (because I haven't zero'd out my laf, right?), and use the 2014 LG tool to flash the Lollipop KDZ. This will cause the data/wifi/bluetooth signals to stop working, as well as losing root and TRWP (correct me if wrong). From there I would need to root and flash back TWRP and then from TWRP flash the LP-[5.0.2]_L90_D415[boot-system-laf-aboot-modem.zip] to get the signals back.
At this point, would I then be at stock rooted lollipop with TWRP and download mode and have a useable phone? If I do a CES flash as recommended, would I lose all of my currently installed apps and data? If so, I should disable xposed first, right?

You WILL lose all data but you need to use CES to fix, I believe, the partitions. You DO NOT have to flash the LP-[5.02]_L90_D415[boot-system-laf-aboot-modem.zip] if you go to KK then to L using Lg Flash tool. After succesful Lolli flash, then root, install twrp, and flash one of Bross's rom.
But if I want to go to stock 5.0, with twrp and download mode intact, what do I do? Flash using LG Flash Tool, root and flash twrp and I'm done? This won't cause radio problems?

I promise, if you follow my guide, everything will be fixed. You only lose radio if you flash something wrong. For example, flashing one of bross's ROMs while on kk. That is a bad idea. After you flash to lolli with lg flash tool, you can root and flash twrp. You WILL NOT lose Download Mode unless you zero out the laf by following the Unlocking Boot loader guide.

Flashing a KDZ back to Stock ROM?

I have CyanogenMod 11 made for the D415 LG L90, but I want to go back to stock because of screen problems and video problems. Can I use the flashing KDZ method with, say, KDZ 10e to go back to Stock Kitkat? Is there any extra steps or precautions while flashing from Cyanogen to Stock? I do not have an SD card, so I cannot flash a ROM through recovery.

[GUIDE] Unlook bootloader, install custom rom LG L90 d410 v20c

I encountered many problems as a beginner to install a custom ROM on my LG L90 D410 v20c Europe, because struggled to receive support, I posted on dozen of posts and never received any answer, since most of the developers have probably abandoned this phone.
So I post below what I did and worked for me. This doesn't mean it will work for you and I assume no responsibility.
PLEASE, USE THIS TUTORIAL AT YOUR OWN RISK, IF SOMETHING WENT WRONG ME OR XDA WILL NOT RESPONSIBLE FOR YOUR LOSS. Always do backups before of every operation if you are unsure of the outcome

I had my phone in a rooted state, with this guide
Then I couldn't find any unlocked aboot for v20c. Some were saying it was safe to use aboot file for 20b or 20s, but some were saying it was risky and if it did work, I would have lost my imei. I eventually also found an aboot for v20c from a russian website.
But in the end I decided to be safe and restore a previous stock version where there was a verified couple of KDZ and aboot. I choose version 10d.
I downloaded the file KDZ of the stock OS from this link, that looks to be from the LG website itself
http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=FW682806432109876543213/D41010d_00.kdz
and followed this guide to restore stock 10d
To download aboot file and successfully unlocking bootloader I followed this guide
Earlier I've tried also this guide and it DIDN'T work for me. It entered in a boot loop that I solved but then it couldn't install any recovery. It might work for you, but it didn't for me.
With the previous working guide I installed the old version of twrp, then restarted, installed the official APP of tpwr and from there I upgraded to the latest version.
I restarted in recovery and backup up my partitions, imei, etc.
At this point the most difficult part is done, and now you just have to follow the standard procedure to install a custom rom and gapps, downloading the versions of your choice in the SD, restarting in recovery mode and installing.
Here more details
I hope it will help other beginners in the same situation as me.
Unfortunately I can't provide support on anything since I'm a beginner myself.

H811 20o/p/q/r rooted kdz

Hello Guys,
My G4 has bootloop issue and in order to fix this, it needs to be rooted and disable the big cores. May I ask if you have rooted KDZ for H811 20p/o/q that you can share to me? I need to flash a rooted KDZ using download mode via LGUP.
Note that zip ROM won't work as I can't boot into recovery due to bootloop issue.
Thanks for the help in advance.
