hi, I'm from Brazil and I'm with this problem as well (CM13, boot loop and PC didn't recognize as qualcomm device), but I cannot find the little point in your picture (I'm not talking about GND, the other point), sorry but my L90 D410hn isn't with me at this moment so I can't send u a picture, what am I supposed to do? (I'll send a pic of mine asap!) thx! (and sorry my bad english)

My phone is stuck in bootloop. Phone is not getting switched off. When I remove the battery and insert after couple of minutes it gets Switch On automatically and reboots again after CynagogenMod's Logo. I can't enter custom recovery because of it. I tried every button combination but nothing seems to be working.

Anyone know where to download these programs at? The links to download these are dead, and if you do have the programs upload them to Mega.nz.
[LG Optimus L90] hvramanan:
I have tried everything mentioned here but it's not working for me. When I connect an USB cable to my LG L90 this is what I see under ports (see device_manager.png attached)

When I use the boardiag application to run the test I keep getting the message "No response from the device. Check PMIC first and if still boot problem, replace AP." See error message screenshot.

I love this phone and want to get back working. Please help me.:crying:
[LG Optimus L90] hooooossamq:
guys.i did all the steps successfully and pass them all.but the phone still stuck in the battery 0% if i try to turn it on.i plug it to the charger and the same 0% come up no LG logo or any thing els>so is that mean its a hardware problem?
[LG Optimus L90] SMOKYxPANDA:
What does the

"1.5 Short the phone resistor;"

mean?

Or how can I do this?
[LG Optimus L90] 0000.0000.00:
If you look at the last picture it shows two points and I think you connect them together with copper wire or something that conducts electricity.
[LG Optimus L90] SMOKYxPANDA:
i've done everything in the correct steps, I just get an error on step 2.8, I get a "device was not found in dload trying flash programmer" under the ports it shows the phone as "Qualcomm HS-USB QDLoader 9008" tried with only the ap check, with ap and emmc, ap and pmic, nothing seems to work, I installed the alternative driver, the L90 driver isn't a program, so I direct it to the folder through the device manager when updating the port, says the phone driver is already up to date, doesn't even install the driver, I delete the driver already installed, and as soon as it recognizes the device as QHSUSB_BULK it automatically installs the drivers, and doesn't let me install the downloaded l90 driver, don't know if it's the driver that's messing up, or the phone...any help?
[LG Optimus L90] 0000.0000.00:
I think you just need to install the drivers like a program and don't install them through device manager. Also you could uninstall the driver with the internet off so it doesn't reinstall, then install the other driver.
[LG Optimus L90] SMOKYxPANDA:
Already tried it with the internet off, seems to reinstall the driver, or at least some driver, and I can't install it like a program, i don't get any exe file, they're only setup information, system, security catalog, and application extension files, the application extension file is a .dll file, double clicked it and doesn't even know what to open the file with, I'm pretty much lost here...
[LG Optimus L90] 0000.0000.00:
Did you disable driver signature enforcement?
[LG Optimus L90] SMOKYxPANDA:
Yes
[LG Optimus L90] 0000.0000.00:
Try installing the inf files manually that are in the normal drivers, but first remove the driver in device manager.

Other wise, PM me because I could use team viewer to access your computer and try a few things.
[LG Optimus L90] Mr. V.:
Hello!

I'm changed aboot.bin to flash custom recovery. After changed, phone black, no boot, no recovery, etc.

Tested this method... working --> black phone to live bootloader or logo.

The big problem: go to download mode and phone say (in standard firmware upgrade screen info box): NOT SUPPORTED and changed version D405 to D410.

Flasher software not flash 405 KDZ to 410.

How to back default (D405) bootloader for this phone?

QPST and EFS not communicate in "good" phone. (for IMEI=0 problem)

All other tools to back stock bootloader?

Thanks!

Solution:

Put 410 firmware (to 405 device) with official Support Tool software. Put 405 hacked bootloader. Bricked again. Low level format, send Bootloader image file. Download mode (405) available. Put 405 firmware and working.

"IMEI 0" problem no problem in calls, phone working without IMEI.

hello

how to flash these files and when i enter the button it shows partition does not exist please extract the files from the total binary image.. WHY
[LG Optimus L90] skyramanna:
Hi... this post is creating an optimism in me for a lovely LG D410, L90.. that broke into a boot loop, and only option was to remove the battery to keep it at peace.

When I found this post, I was delighted, and I then followed the entire process of shorting the test point to ground, and got the HS-USB QD Loader 9008 on the Device manager consistently. I then followed the further instructions to download aboot, BackupGPT, but when I tried the restore boot img with 'boot', I got this error "boot partition write fail.. sector 0x50000 test aborted". I tried several times ending at the same. Can any one guide me from here?

---------- Post added at 02:44 AM ---------- Previous post was at 02:26 AM ----------

Hi guys.. now I am not sure what worked.. I tried one more time after logging the above post, and voila.. the flashing of image files are completed one after the other without any error.. ! However, after I reconnected the battery and to USB, I get flashing battery charge icon at 0%!!.. The same repeats even if I plug to main charger.. I made a progress.. but still way to go.. any clues how to come out of the battery icon flash issue and what it means??? The phone does not start when I press power button... after a while, I see LG logo also is flashing alternately with 0% charge indicator.. dont know if its a battery issue.. getting optimistic further.. but not sure what the fix is..

You made it possible to save my device. Was sure it was a gonner and that I made 1 mistake too many to be able to fix it myself. Thank you so much!

Umm..... How did you get the IO shield off?

---------- Post added at 06:25 PM ---------- Previous post was at 06:21 PM ----------

So I hardbricked my D415. I don't know how exactly but there was a guide on XDA where it mentioned flashing aboot and using Flashify to flash TWRP. Now, Windows sees my phone as multiple drives (probably every single partition) and no qhsusb or Qualcomm 9008. Should I try this method?
[LG Optimus L90] 0000.0000.00:
The d415 doesn't need its aboot flashed to unlock bootloader you just need fastboot to do this and the IO shield just pops off.

[LG Optimus L90] DavidXanatos:
My phone is being detected as "QHSUSB__BULK" not "QHSUSB_BULK" when i force it to install the driver, the b2b application complains when I press start.

the log says Failed during lading flash programmer

Test Aborted!!!

I did not have to short the pin to get to this state, just hold down he power button and plug in the cable.

is that wrong? do i need to short the pin in any case?

Also I see a device called "Qualcomm MMC Storage USB Device" which appears to be the internal MMC exposed as a normal writable usb drive can I use this somehow to flash the flash? DD some image files to it may be?

Updating the drivers as said in the first post does not work as the device name is slightly wrong, reinstalling them manually also does not help.

If it remains it's likely your phone had an hardware related issue, this guide only works for software problems.

[LG Optimus L90] patriotvinny:
Hello, I wanted to thank you for such a good tutorial. I recently bricked my lg optimus l90 when I accidentally accepted the latest android update. Phone restarted during the update, then turned off and it never turned on again. No download mode, no splash screen, no recovery. Its completely unresponsive. When I hook it up to my laptop, device manager see's it so that's not a problem. All my drivers are installed. I managed to short out the phone (as described in the tutorial) and get it into Qualcomm HS-USB QDloader 9008 mode in device manager. However when I use boarddiag I get an "error device not found in dload trying flash programmer" or sometimes I get this error "No response from the device. Check PMIC first and if still boot problem, replace AP". I have been at this for hours and I keep getting these errors. The Boarddiag software just refuses to see my phone despite device manager not having any issues at all seeing it. I have all the same options ticked as in the tutorial and triple checked my com/port number, everything is correct. I am using windows 7 on a x64 system, not sure if this is a problem for Boarddiag. I have googled this problem and did find that a solution is available, however those solutions are for phones that are not taken apart because it requires the battery being pulled out. In this case there is no battery and the phone is taken apart, so those solutions would not apply to me. I guess my question is, how do I get Boarddiag to recognize my phone while its taken apart. I'm sure its probably something so simple but since I'm a noob to this I probably will never see it. I will continue to look for answers and check back periodically. Thx in advance for any help that you may be able to offer. Your efforts are very much appreciated. :good:​
[LG Optimus L90] neverdies:
Hi, as you can see other members are facing the same problem than you, I tried to help them, but without success. I still can't understand what causes the error, so to help you I need you to do some tests. If it's ok to you let's do it.

First off all I need to know if you're removing the test point after getting the phone recognized by device manager.

Your approach, removing the battery I think this should be only to de-energize all the components from the phone motherboard.

-> By removing the usb cable and wait some seconds, you will get the same result, you can also press power button for a faster discharging process.

-> Try also the 1.1.3 steep: Restart the pc and press F8 repeatedly, a boot menu will appear, select "Disable Driver Signature Enforcement".

After this two steeps try again and report the results.

Good luck.
[LG Optimus L90] Floating Point:
As I suspected, there is a smarter way to recover from this kind of brick that your phone shows as mass storage in Windows.

When we extract the KDZ, along the partition files we get the sectors (blocks of 512B) where they must be flashed (eg.: recovery_372736).

You can simply boot Linux and use DD to flash the necessary partitions to boot in download mode or recovery, I was about to write something about this but someone already had this same idea: http://xdaforums.com/showthread.php?t=2582142

Yes, you need Linux, I don't know how to do this in Windows.

Also, I think this way is much safer since you wont touch your modemst partitions (the infamous 0 IMEI problem).
[LG Optimus L90] neverdies:
If you follow my guide, only, you won’t touch the modem partitions, you will only mess with them if you format the mass storage device (fat partition), as described here: http://xdaforums.com/lg-l90/general/how-to-unbrick-hardbricked-phone-t3100163

But you are right too, if you flash the right image to the right partition you will end up whit a working phone, also the right IMEI.
