ye, i think win 8.1x64 was the problem, i succesfully downgraded to 4.4. from win 7x64
[LG Optimus L90] xanscorp:
Mine only recently started having issues, except I receive a "stopped responding" and "debugging" error request. It used to work in 8.1, but I don't know what LG's deal is lately. The most recent version and drivers seem to give this issue.
[LG Optimus L90] DallasBelt:
Thanks a lot man, you saved me! Finally I flashed stock Lollipop on my device :)
[LG Optimus L90] H84:
where can i find stock d40510A ?

i have search but cant find it anywhere, just lollipop

or. if i have lg l90 d405, is d40510d the one i should have ?
[LG Optimus L90] Tejas tedi:

[LG Optimus L90] H84:

Hello all,

could anyone for the love of GOD please get this file from a D405n so that I can unbrick my phone please?

Thank you all
[LG Optimus L90] H84:
nothing works for me ! :p

the whole story so someone maybe know whats wrong.

i first uppdate to stock LP through OTA, but then flashed back using kdz to KK and installed cyanogen 12.1

then i wanted to go back to stock LP, and first KDZ to KK (maybe didnt need this) but now i am there, now i cant use KDZ to flash LP, nothing happend, tried everytginh.

and neither using official Lg Pc suite works, it says i have an uppdate, and start downloding but get error when tried to flash ??

so for me´, it maybe seems like mine phone is on LP ?? :P
[LG Optimus L90] xanscorp:
Depending on your variant, with the OTA available, it may block the Flash Tool as the flash tool detects the OTA. If you have a custom recovery you can try Brossovitch's uploaded zip format of the stock LP.

and i after that tried to flash my KDZ that before didnt work, But now it work and it flashed through 100% ?? :)

thanks for paying attetnion to my problem :)
[LG Optimus L90] krazyq:
Sorry for noob question

Does the phone need to be rooted for this?

Thanks
[LG Optimus L90] xanscorp:
To flash the stock kdz with LG Tools, no. Only download mode is needed. In most cases, flashing stock kdz will unroot anyhow.
[LG Optimus L90] dr.spider:
Thnks for the fix! I got my phone bricked with cettification error 640! after OTA update of LG :/

And download mode with volum up and power on was not working by my phone anymore..

But I did it on another way wat also worked for me pff

just:

- put out the battery

- plugin usb (yes without battery inside)

- hold volum up and put battery back in phone (same time)

and I was in download mode :)

Maybe hany if you put this way also in the topic start for ppl that can't in download mode anymore via normal way..

Im verry happy that I fixed my phone with your help :)
[LG Optimus L90] modestas7152:
any way you could help me? Been struggling with my phone (d405n) for few days now, my pc sees androidnet device with drivers installed, and ...usb_hub without drivers. Tried flash tool, lg support tool nothing works, flash tool get's stuck at 4% or doesn't recognize device, support tool says that battery is too low even though it's fully charged, tried changing ports etc.. It seems that I can't get my phone to enter download mode or any other mode with button combinations... when connected to pc, fat partition comes up with 2 folders image and verinfo.. The problem started (in all my stupidity) when I flashed wrong recovery img to the phone... I'm using windows 8.1 x64, got all the drivers installed, tried flashing with d405n10c, d405n10D, d405n20a.. The only thing left in my knowledge is try the guide with boarddiag, but either the guide is too complicated or I'm too much of a noob for it....
[LG Optimus L90] :
Try to go in win to devices and printers (just search) and see if there is the lg l90. Open properties of it and click hardware. Now open each hardware thing inside it and click at drivers remove uninstall or so. This way (when you done this for every hardware piece) unplug phone, reboot windows and let it load everything. Now plug phone in and it will get recognized as a new one (including reinstalling all drivers associated with device). Hope this helps.

Edit: Sorry for any grammar issues (as I saw them too :-p ) but it is really hot here in the Netherlands which makes me kind of lazy :)
[LG Optimus L90] modestas7152:
done that already, my pc doesn't recognize device as l90, but rather as AndroidNet device, I've reinstalled drivers countless of times... :/
[LG Optimus L90] BadChoices:
Probably you have installed some wrong drivers on win 8.1 & now the Os cant detect the correct phone model as far as i understand.. im also running win 8.1 x64 on my desktop and after installing the LG drivers the only thing, for now, that i cant manage to get to work is fastboot, because i get the error "waiting for the device", but that's another story, either you have messed up something regarding the drivers or maybe some other installed device on your rig is causing that, maybe a printer ? a camera ? are you connecting the phone to the pc via an usb hub ? try to connect it directly, something usb related is causing that to happen, you can check as well your main board usb drivers, best option is to remove as many installed devices/drivers till you find out whats causing this issue to happen.. even though that you don't need at all to install any drivers to make the phone been seen/recognized by win 8.1, don't forget to activate the usb debugging mode under developer options on the phone, i have a d405n as well and trust me that the most times we are the guilty ones causing the device to go bananas ;)

best regards.

alert > To use custom ROMs on this device, you must either come straight from stock kitkat, or flash the appropriate kitkat bootstack for your variant. Otherwise you will have a broken baseband, which means no mobile network service! You must also have a custom recovery already installed, and your bootloader must be unlocked!

/edit

Could anyone please, tell me how to install or to get/find out which is the lg keyboard that comes by default with the KitKat stock rom _ D405n10c_00 ??

[LG Optimus L90] dnuuk:
Saw the problem somewhere on this thread but didn't get to the solution (read all 30 pages and nothing)... I'll give you some background hoping you could help me with some fresh new ideas on where to turn to, where to search for answers... I'm in Mexico, so it means I own the Mexican version of the L90 which is D400hn (dunno what H stands for, N i've read it's for NFC) ok, that being said... I continue, everything was good until five days ago, I got kinda like desperate because the phone was sluggish, I flashed the D400hn before one time with a posterior root treatment by PurpleDrake method (also installed CWM recovery, just in case)... ok, I couldn't get my phone now ready for a KDZ flash... I've read around that it happens because you "trespass" (for calling it somehow) LG's protection and even If you were on root or carefully unrooted, the unit wouldn't allow the user to flash it (LG wasn't gonna make it so simple for everyone, that's understandable), well, don't know for sure if this is true but wouldn't doubt it either... ok, back to my issue... I got pretty desperate and used that CWM to try and flash a custom Lollipop ROM, to my surprise, they were outstandingly good on my phone... only major issue I had was that none of them detected the sim card (how odd I thought! ah! and the camera issues and a few non relevant issues)... well, researching I found out about something called "Bootstacks"... and oh what a salvation! Flashed BOOTSTACK_v1.4_D405N-10F (Note it's intended for D405N, couldnt find anything about my own local model) and voilá! The sim card was operative and the skies opened up and sun shined down to my hand beholding that beauty... but well, as every sad story my cellphone and me both had our tragic ending... I thanked the bootstack creator in his/her thread, who quoted me soon after that to let me know I was getting a bootstack taylor made only for my device... and because of being thankful and anxious couldn't even wait and flashed it... holy crap! NOW... my cellphone has this nasty " Boot certification verify : SECURE BOOT ERROR ! " and I can't get to recovery (with the buttom combination I almost get there, Factory reset like you know? but then it all goes pitch black and completely irresponsive and dead lol... I can't get to fastboot to push any ADB, still any of the flash, recovery, test, or any kind of tool from LG don't even notice my device, I've tried in two different computers and I'm STILL HAVING A BEAUTIFUL BRICK! :(

So guys... do any of you have any answer that may be helpful to this situation?? Is it possible to push or flash something from Download mode? some sort of Odin-like app that can take me out my misery ASAP? guys?

sorry for writing so much, I wanted to give you guys a clear idea to try to get the most accurate help possible, thanks a zillion in advance for being so kind to read, share your time as well as your knowledge! :)
[LG Optimus L90] xanscorp:
If you can get into Download mode, but not a recovery to flash your initial .zip (you do not have to be able to see it, just enter it), you may be able to use the FREEDOM_PACK_30E to access adb devices and adb shell and use a push to reinstall the Recovery to the phone. From the recovery (if you have a backup on your SD Card,) you can flash a backup. If not you can download a recovery in .img format (like TWRP) and a ROM in .zip format to install to your device. The following are the instructions to use in adb shell:

adb shell

dd if=/sdcard/%imagename%.img of=/dev/block/mmcblk0p17

reboot recovery

C:\adb>adb shell

1|root@w7:/ # dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p17

dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p17

(It will show something like) 22832+0 records in

22832+0 records out

11689984 bytes (11.1MB) copied, 1.828023 seconds, 6.1MB/s then enter

reboot recovery

That should get you back into your TWRP or CWM (whichever .img file you used) to be able to flash the ROM, or backup.

[LG Optimus L90] JOuzts:
Negative. This will only flash stock LP ROM. I don't know if you could even find KK flasher. This won't. Only way I know to get back to KK is through Recovery. Don't forget they're different bootstacks...

Download your kdz using ur IMEI

Here are the steps :

1) Type this in your browser

http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI

2) Replace IMEI with your IMEI phone's code

3) The browser will display some html codes

4) Look for text something like :

http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW567986573210987654321/D41020A_00.kdz

I used this guide after I found out that my loader was already unlocked. I 'unlocked' it, and screwed up my laf partition. I used the stock kdz and the LG toolboth mentioned in OP to return my phone to STOCK. Huh, why, idk? I'll never go back to stock, if you have a custom recovery already installed, and want to stay as close to stock as possible..... Brossovitch has several 'stock' ROM options. All are debloated.

Wondering if any one can share his QCN file for LG L90 D410 (Dual SIM), I had got my phone hard brick, though i was able to get it up and running but no signal for both sim, later managed to get one sim working but no lead for second SIM to set its IMEI, would be of great help if some one can make a back up of his working phone qcn file and few digit of both IMEI number so that I can read the location and replicate with my own phone with my original IMEI.

Omg you're a lifesaver. Worked like a frickin' charm!
[LG Optimus L90] andrewz1986:
Hi guys. I'm a newbie, so please be nice to me. :)

Long story short:

I tried to go from Lollipop back to Kit Kat with my unrooted L90. Everything went fine, but when I should "JUST RELAX!", the flashing process ended at 4 percent on the LG Mobile Support Tool side (0 percent on the phone side in Download mode) with a message "Upgrade stopped due to an error". What am I doing wrong?

Short story long:

I bought LG L90 D405n. It was never rooted. It came with Kit Kat. I haven't found any complains about Lollipop, so I immediately made an OTA update. It went fine, but I'm not happy with Lollipop. I would like to find out whether Kit Kat would resolve some of my problems with Lollipop, so I wanted to downgrade. I mistakenly flashed Lollipop ROM with Lollipop ROM first. The process went fine, but I did not move forward in any way.

So I went back to

lg-phone-firmware.com/index.php?id_mod=55

to download stock ROM. "21 CZE/CZECHO" KDZ file was relevant for me. But the download link is dead. So I downloaded KDZ file "55 POL/POLAND" from other source

androidfilehost.com/?fid=24052804347761023

(links also dead on lg-phone-firmware; the RAR "D405N-POLAND-10B-kdz.rar" file contained MD5 and TXT files that I ignored). I followed exactly the same steps, but was not succesful in flashing the ROM this time, although I made it before. When I should "JUST RELAX!", the flashing process ended at 4 percent on the LG Mobile Support Tool side (0 percent on the phone side in Download mode)

goo.gl/wAv83e

with a message "Upgrade stopped due to an error"

goo.gl/nlz72g

. I tried to reconnect the phone, but it did not help. The phone is fine, but still has Lollipop.

Why didn't the flashing process run fine this time? Is the downgrade itself the problem? Or is it the language? Or is the ROM (filename D405n10B_00.kdz, size 0,98 GB/ 1*053*060*098 bytes) I downloaded from other sources faulty?

Thanks.

Edit: I tried a different USB cable and different ROM "D405n10c_00.kdz" straight from lg-phone-firmware.com/index.php?id_mod=55 . I got the same negative result. :(

Edit2: I'm not alone. forum.android.com.pl/topic/191713-flashowanie-stockowego-romu-kdzunbrickowanie-telefonu/page-9

Edit3: I tried "Upgrade Error Recovery" feature withing LG Mobile Support Tool. The flash process went ok, but it was also "no-step-forward" Lollipop to Lollipop case.

Edit4: I tried to go from Lollipop back to Kit Kat via Windows 10 (not via my primary Windows 7 as before). I tried a different USB port. I got the same result. Maybe I'm attempting to flash faulty ROMs. Which one should I download?

Edit5: I gave up. I would probably have to use cwm/twrp method to go back to KitKat, which would require root. When warranty is over, I will come back. :)
[LG Optimus L90] ASPViTo:
WORKS !

My phone was bricked while i try to flash a custom recovery (used TWRP_2.8.5.0_120215_L90.img), i used this method described here and voila after flashed version 20c it booted normally, just to say a big thanks to you guys !
[LG Optimus L90] Floating Point:
As long download mode is available, it's easy to recover everything and return to plain stock.

To install TWRP, don't forget to unlock bootloader first, and use the right D410HN hacked aboot image file. Do not use the russian D410 version.
[LG Optimus L90] abhay03533:
In my case, even the Download mode was not coming still method mentioned at #323 works swiftly, the only issue is with lost IMEI number, which in case of single SIM easy to do by editing item number 550 of QPST download tool , but in case of Dual SIM, editing NV item number 550 will only fix single SIM, not the Dual SIM. Still looking for a solution to make second SIM working. I guess it can be done if someone is ready to share his qcn file

---------- Post added at 04:33 AM ---------- Previous post was at 04:25 AM ----------

Was it a LG L90 D410 dual sim variant, if so can you please share your qcn file. I need to repair my second sim IMEI
[LG Optimus L90] Floating Point:
That recovery method override your modemst1 and modemst2 partitions info, your phone modem is not a D410HN anymore, now it's the russian D410 single SIM version.

I always say here, after rooting, before doing anything, backup your modemqst1 and modemqst1 partitions with

dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst1 of=/storage/external_SD/modemst1.img

and

dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst2 of=/storage/external_SD/modemst2.img

These partitions cannot be recovered with regular kdz flash, they are unique to each phone, can only be flashed with twrp, adb or terminal IF you have backed up them before.
[LG Optimus L90] abhay03533:
I disagree a bit (or may be you can help me understand better) as I can see all functionality and properties of Dual SIM listed and associated with populated services like (nw mode, data service selection etc). Even *#06# still shows both IMEI, one of non working SIM as 0. So I believe my phone is still Dual SIM
[LG Optimus L90] Floating Point:
You modemst is russian.

Your system is from another dual sim variant.

The app that show second sim blank because it cannot retrieve the info from modemst partition.

You can even hack the app to show more sim cards, but since it cannot retrieve the data from the modemst partition, it's useless, just the first one matter.
[LG Optimus L90] ASPViTo:
Damit !

Was everithing ok, since i read this issue about lost IMEI, my phone shows two "zeros" when i type *#06#, but i still can do calls with my 2 simcards, but i noticed when i got to another city, i lost signal on 2 carriers, i dont know what to do.
[LG Optimus L90] abhay03533:
Do you have backup of your qcn file ?
[LG Optimus L90] ASPViTo:
sorry

Sorry bro, i am not a big noobie, but i dont know where this file was, and i did not make a back up before did the ****, sorry again, but i may ask, where are this file ? (I have root)
[LG Optimus L90] Floating Point:
I don't know why they are talking about qcn and efs in LG phones.

What is known to backup your IMEI and other precious unique info from your phone in LG phones is the backup of modemst1 and modemst2 partitions.

After rooting a LG phone, before doing anything else, backup the modemst partitions and keep in a safe place, in case of lost IMEI you can recover with those partitions.

Or even better, make your own unbrick image with dd if=/dev/block/mmcblk0 of=/storage/external_SD/unbrick.img bs=512 count=323583 and don't share with anyone since it has your IMEI data.

If you lost them by making a direct flash in NAND using someone else unbrick images and don't have your backups, you are lost.
[LG Optimus L90] ASPViTo:
so...

So There is no way to put back IMEI info on my phone ? By any means ?
