Thanks it's work now all good i can see qualcomm, but It's not my problem coz when i start phone its still the same problem i mean when LG logo dissapear automatically running android update 2/2 part and after several seconds i have error on black screen. I think i need format but i don t know how to do it, i saw yestarday i can go into s/w mode but lg flash tool don t help too with installing new android, on computer i have 4.4.2 and lollipop for lg l90 and i just can see after installing 4.4.2 in s/w mode i have rooted device but nothing more it s still the same problem with update. I think error say something about fonts. :rolleyes:

Edit:

I install 4.4.2 drivers in lollipop from this hardbrick.zip and that s why perhaps its not working, i install drivers from lollipop and now i don t see update but just logo and i can t get into recovery, i try install now original KDZ

Drivers i mean it s just what we see in RESTORE BOOT IMG and i changed these file to lollipop

This Works But...

This Works but now in "About Phone" shows V120b-OP1-HQ.

Formerly V20b-SCA-XXX and now the frontal camera doesn't work!

How to Fix this?:confused:
[LG Optimus L90] Floating Point:
I think you used the recovery images from a different model to launch download mode. The hardbrick file is nothing more than the partition tables and partitions images backups until the laf mmcblk0p15 of an unknown L90 variant (probably D410 dual-SIM without NFC). I believe you are able to fix this by rooting, unlocking the bootloader and flashing the whole bootstack from you model. When I say whole, I mean all partitions you'll find inside the KDZ of your model (except for GPT tables of course). A TWRP flashable zip can be easily setup for this task. Many people can face this problem but I think this is the solution, the hardbrick file is a good start so you can launch download mode and after flash the proper images of your exact model.

I'm not sure this will solve your problem, but I believe this is the cause. :good:
[LG Optimus L90] Thi_Memoria:
Tanks

Ok, I have the KDZ my unpacked device. and it contains these files; aboot abootb BackupGPT boot cust factory laf modem persist PrimaryGPT rct recovery rpm rpmb SBL1 sbl1b sDI system tz TZB all accompanied with a numbering system and divided 17 part example: system_933888 system_1197064 system_1201176 tz_150528 tzb_157696 etc ... What should I do? :rolleyes:
[LG Optimus L90] Floating Point:
Whats your variant and what kdz you are trying to flash (kk or ll)? If your bootloader is unlocked and you have TWRP installed, I can arrange the flashable zip for you, all you'll have to do it's to drag and drop the files into the zip.

The multiple system binaries can be merged in the LG Firmware Extract, there is a button to merge all in a single img file, this one can also be used to flash your system partition.
[LG Optimus L90] Thi_Memoria:
Tanks again

So... I flash all available partitions KDZ and yet this V20b - OP1 -HQ the only partition that I found in KDZ was the " MISC " would be the problem ? I take this partition and flashing by fastboot ? I have unlocked bootloader and TWRP recovery and fastboot mode too!

I have another D410hn! Maybe i make backup the misc partition and flash on my device!

---------- Post added at 03:59 AM ---------- Previous post was at 03:51 AM ----------

So... My variant is D410hn Brazil V20b Lollipop! Here the link to my kdz: csmgdl.lgmobile. com/dn/downloader.dev?fileKey=FW6332R032URAYPC7CBB62W/D410hn20b_00.kdz
[LG Optimus L90] neverdies:
Hi [MENTION=6863179]Thi_Memoria[/MENTION] sorry , I've been a little busy , and so I've not been able to watch this thread as much as I wanted.

Now that you have the phone working you have to flash (offline) the KDZ suitable for your device.

Here you can see how to flash your kdz: http://xdaforums.com/lg-l90/general/guide-flash-stock-kdz-offline-lg-l90-t2803479
[LG Optimus L90] Floating Point:
Mine is also the brazilian variant D410hn.

The files you flashed to get access to download mode are from the Asian CIS D410 (dual-SIM without NFC).

I unlocked the actual D410hn bootloader and made the proper bootstack for our version.

Make sure to be using TWRP 2.8.7.0, I didn't tested in older versions or CWM.

Bootstack - this flashes all D410hn partitions, except system: http://www.mediafire.com/download/mzc4qt5a7r79rcl/Bootstack_D410hn_Lollipop_v20b.zip

If you are willing to return to Lollipop (boot/system). This is the flashable android zip to install system without KDZ: http://www.mediafire.com/download/i2ijgbwa07o2ugf/Flashable_D410hn_Stock_Lollipop_v20b.zip

Before flashing the big lollipop (second zip), wipe data/cache/dalvik/system, since it's a huge file, It takes around 10 minutes to flash. Also, after that flash SuperSU: http://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip then reboot and check if everything is back to normal.
[LG Optimus L90] Thi_Memoria:
Solved?!

Ok I know about Flash KDZ Updater and I found out where the problem is! he is in MISC partition and CUST partition, I edited files CUST partition with Root Explorer and now is normal and front camera working now! I edited these files: cust.prop cust_grup_mapping.cfg and cust.prop of open_sca folder. Tanks for All!:good:
[LG Optimus L90] Floating Point:
The flashable bootstacks I made for D410hn also flash CUST partitions, this would have solved your problem too. In fact flashes all partitions in kdz, except boot and system that are in another different zip. With those two files you can flash everything in TWRP just like lg kdz would do if you have your partition table ok.
[LG Optimus L90] Thi_Memoria:
Help

So... I flash this Bootstack_D410hn_Lollipop_v20b and my imei is now "0" :mad:

i'm downloading the big zip now
[LG Optimus L90] Floating Point:
Weird, because I flashed kk and ll bootstack multiple times between kk, ll, cm11 and cm 12.1 flashes and my imei remains the same. Try to flash system and boot of the big zip.

Edit: Sorry for the wrong info, it doesn't flash misc partition since it do not exist in kdz, I see you modified some files in misc partition, this might be the cause for your lost imei.

If nothing works, try to flash the foreign d410 lollipop bootstack: http://xdaforums.com/lg-l90/development/bootstack-kk-l-l90-t3118632 you flashed another variant unbrick images I believe some "unique" partitions were overwritten by this flash and your phone no longer is a d410hn anymore at software level.
[LG Optimus L90] Thi_Memoria:
Nothing...

Nothing work... imei=0 imeisv=0:rolleyes:
[LG Optimus L90] Floating Point:
I took a look into the unbrick images you used and I could identify that they came from the D410 (dual sim no nfc) v10d kitkat. I would try this two things:

1 - Flash D410 (dual sim no nfc) kitkat bootstack and CM11 (since it's a smaller file, just to test and see if you have you imei back).

If it don't work:

2 - Return stock lg recovery and flash KDZ via LG Flash Tools in emergency mode.

You can extract the binary from the KDZ (LG Firmware Extract, extrack kdz, then dz and extract the recovery_numbers.bin), name it recovery.bin, put in the root of your microSD and flash in terminal or adb with:

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

Or use Jrummy ROM Installer.

Then follow this guide: http://xdaforums.com/lg-l90/general/guide-flash-stock-kdz-offline-lg-l90-t2803479

I have 2 L90 with the unlocked bootloader I made, I flashed the bootstacks hundred times to go between almost all custom roms available here in xda and stock and never faced this problem, probably something changed when you got the hard brick and flashed the d410 l90 variant unbrick images so you can never change your bootstack to d410hn again, I never flashed other variant files in my two L90 and they both are ok.

If nothing more works, unfortunately, I believe the only way is to make the test point again and redo the whole process :crying:
[LG Optimus L90] Thi_Memoria:
OK

OK i am download this now and i have the cm11 installed on my device!
[LG Optimus L90] Floating Point:
Make sure to flash kitkat recovery if you are using kitkat bootstack.
[LG Optimus L90] hessien zaghloul:
i used another battery and still rebooting
[LG Optimus L90] jamiscs:
Try to put on download mode (holding Vol + before connect USB cable in the moment the phone turns off), it may make the phone stop to reboot.

If doesn't work, disassemble the phone and put in on Qualcomm HS-USB mode again followng the guide.

But right before you flash the files, do this:

Check the EMMC box

Select laf on the partiton, side of this checkbox

In option, choose erase and hit Start

Then check "restore boot partition" and flash the files in order, but not the laf.

So, try to put in download mode again. Without the laf partiton, the phone will be forced th use fastboot mode.

I'm not sure if this will work.
[LG Optimus L90] hessien zaghloul:
still rebooting
[LG Optimus L90] jamiscs:
Lol. I have no idea why my phone stopped to reboot :(

I think if erasing the boot partition (with the method that i told), it will stop to reboot and stay on fastboot mode. But I'm note sure of this...
[LG Optimus L90] hessien zaghloul:
anyway thank you for your time<3
[LG Optimus L90] Floating Point:
I know L90 fastboot were butchered by LG to cut a lot of commands, but maybe this can be useful for our device to avoid the trouble into making a test point: http://xdaforums.com/android/software-hacking/guide-how-to-reboot-to-edl-fastboot-t3394292

I'll try to find out if our device supports this mode.

For anyone willing to test this, plug your phone in USB debug mode and send adb reboot edl, your phone will turn into a black screen and QHSUSB_BULK will show up in device manager. You'll have to install the drivers provided in the topic, after that, it will become Qualcomm HS-USB QDLoader 9008, but fastboot won't accept any command, won't even detect the device although is recognized in Windows as the QDLoader 9008.

[LG Optimus L90] neutrondev:
[MENTION=7284204]dusan17[/MENTION] please never reply to a long post like that; nope you do not need to solder a wire or "weld it"

Before you plug usb in the phone the gnd and that point need to be shorted out. After that you can release the short. You can short it out by keeping 1 cooper wire between them.

Caution: if you short other pin to ground than the one shown you might fry the cpu, emmc or power circuit.

I realized this same software provided for unbrick can dump the phone nand in bricked state.

With some hex edit, you can dump the necessary partitions and keep your dual-SIM capability if you are on D410hn (or any other dual-SIM variant). If you flash the russian D410 image in your phone without making any backups before the brick of before trying to unbrick with the testpoint method, say bye to your SIM2 IMEI.

I'd like to have in my hands one of those bricked D410hn of the topic to test this and see if unbrick without any bad side effects is possible.
