LG L90 D415 accidentally I changed the "bootloader" - LG Optimus L90

I have a LG L90 D15 and accidentally I changed the "bootloader"; but now I can not turn, I can not even access the "S\W Update" mode.
I have the file ".kdz" but nothing yet, because I've put volume + and connect the USB cable to the PC, and nothing.
Some help me.

The unbrick a hard brick would help but I think it doesn't work well with D415 as many people have reported... Your only hope I think is fastboot, but I don't know much about it, just that you will need laf partition and command line. There are a few threads about it if I remember correctly.

Thank you, I could solve the problem. I have to wait to see if someday find the solution. Meanwhile I have to stay without cell.

I remove the battery and connect the power charger or PC and show me on the screen a cable with a battery and an exclamation point. If I put the battery is not detected on the PC.
Some help me.

No. Not unless you throw your phone at the wall halfway through the processes.

Maybe your USB port is at the cell is broke... Or did you already try, to plug in the cable without battery in the phone? Did you try to directly flash a kdz file with smartflash, or did you unpack it to bin/fls files before?

The charge images are inside the boot partition if you overwrote that partition it would not show images when charging. What OS is your PC running? If its Linux run lsusb or cat /proc/devices to see if it detects it. Windows doesn't play nice with bairly working devices. I have no idea about how Mac handles it.

Same Here
Hello,
I have exactly the same problem as statet above. My phone is totally black.
nothing happens when i put it on charger,
nothing happens when i hold power button,
nothing happens when i hold power buton + down volume,
nothing happens when i remove battery, hold down volume and plug in usb.
My phone worked fine, i have used like 3 or 4 roms. i made a backup of a ROM.
This went totaly succesfull, just as it did before a couple of times.
After this backup it rebooted succesfully to my CM10 nightly.
Then it said my SD card got dismounted and i opend ROM manager and clicked on reboot to recovery.
and then i got in the situation where i am now.
can anyone please help me? im pretty scared that i bricked my phone.
Which is kinda odd because it wasn't aborted during any flash or backup.
Hardware cannot be damaged right ?

I would recommend sending it into repair shop. At this point we can't do anything if SW update mode is nor accessible. I've been working on a way to recover with shot bootloader but to no avail.

ATT (ROOTED) Lg Flex wont boot. Help! (please)

So I woke up this morning (after going to bed listening to audiobooks on sleep mode) to find my brand new flex would not power on, did not respond to charging, and I even tried to use paper clips on the two small holes in case it was a soft reset ability.
I had to leave on a business trip for a few hours, but before I left I USBd to the laptop, and it found about twelve drive partitions all asking me to format. My questions are numerous, but primarily I want to beg slash ask ;
1. Any advice on what to do?
2. Were those drives all related to the efs partitions in another thread?

What's the device listed in device manager? Sounds like your phone is hosed...Partition tables got messed up.
You might be able to restore it in Linux using dd. Can you get into download mode?
return it; if its brand new, dont mess with it, just get it replaced..
EDIT: I see you rooted it; what exact method/steps did you do?
I hosed my G2 a month ago. Tried 3 or 4 ways to bring it back but nothing helped. Lesson learned to back up EFS on laptop and phone before anything. I had mine swapped out but took a few days. Good luck.

Have exact problem...I can get in download mode but dont know what to do from there. I tried adb and fastboot commands but it cant find device. Anyway to get it into fastboot mode or how do I use download mode so it will boot again. If powered on it tries to boot like it is updating (the blue line under android) then he falls over dead with the triangle. If I could get it to connect to my pc via usb I can do the fastboot flash of the .img files. Thanks in advance

We already tried some of the ideas of the Ubuntu VM dd commands as well as some other stuff.
If someone can continue this work to get G Flex into download or fastboot mode like others did LG G2, than share there or here...
I'll be more then happy...

[Q] Did I just hard-brick my Xperia T?

Hello.
I was installing different boot.img by Flashify app. Then I was asked to restart my phone, pressed the button and... nothing.
My phone doesn't turn on, LED doesn't blink while connected to adapter, phone is recognized as Qualcomm HS-USB QDLoader 9008.
I'm 99% sure my phone is hardbricked, but I'm not going to lose it. If there are any possible solutions to recovery it, I'll risk to keep my phone alive (or dead).
Thanks for any response

If it is hard bricked then open the phone disconnect the battery and reconnect it..then use flashtool to flash a kernel with recovery and flash another rom..you should then be good to go!
@PeterGeorgiou already tried it, gives nothing.

Try to press and hold volume up and power simultaneously and connect to pc. I managed to recover my XV that way.
If it doesnt work, take battery out and in and retry.

Still nothing :/
Second question: is there any chance that if I send it for a guarantee, sony experts won't find that my phone was modificated?

All you have to do is put the phone in fastboot mode and use Flashtool to flash a stock kernel or the kernel for your ROM if you're on a Custom ROM, which is the first thing a repair shop will do if you tell them what you did and/or if they really are "experts". You should google how to put your phone in fastboot mode since I've already heard about several people saying they've ruined their phone when in fact they just have no idea how to put it into fastboot/flash mode properly.
If they manage to boot up the phone they will see that you've at the very least rooted your phone and installed apps that require root, so you might want to consider that.

If I was able to put my phone in fastboot mode, I wouldn't make this thread. Main reason of creating this topic is that I can't access my phone in any way including many combinations of keys, disconnecting battery etc.

I know, I'm just saying because, just as you, I've seen other people make threads because they say they can't do this and that, and then it turns out they just don't know what they are doing. You wouldn't be the first person who couldn't get into fastboot mode, when in fact, didn't know how to get into fastboot mode, which is why I reminded you, because if a Sony Service Center does in fact boot up your phone and see you have rooted, that might most likely void your warranty and you'd have to pay; so it's best if you really figure out if you actually know how to get into fastboot/flash mode.

NeoWave is based on Omnirom... not CM11.
Boot.img had to be installed by Flashtool or manually in bootloader mode.
The only way is to connect to PC pressing volume UP.
Power+volumeUP is a good way to reset a wrong kernel.
No sign from your phone? No blue light?
Have you tried to change usb cable? To change PC?
If there's no red light when you connect the recharger, it's a bad sign though

Sorry, my bad.
Haven't switched USB cable (I've got only one), but I'm sure it works because I've checked it on my secondary phone.
Tried to do it on PC and also on my laptop, both don't work.
And a really bad thing is that when I connect my phone to recharger there's no red light.

Perhaps you need to find a way to recharge your battery because it's to low for anything to happen?
Someone should inform the Flashify developer that his app bricks our phones.. Perhaps he can add some kind of device check to prevent this in future.

There are some chargers like that on the market.

Or just buy a new battery, which has always a little charge before installation.
A wrong kernel doesn't allow to recharge and the battery may discharge quickly, that's true, but the fact that after rebooting there was no sign is a very bad thing.
Maybe the battery was suddenly fried... who knows.. Yeah, give it a try.

D405n fully bricked - problem

Hello,
few days ago i unlocked bootloader and installed twrp on my l90 d405n. Unfortunetly, something went wrong and now my phone is fully bricked. Windows see the phone only as 60mb disc with two folders, on phone screen is still black.

it may be due to bad recovery version o rbad aboot? What can i do?

Is there any hope for my device??
come on guys we need a fix please help
If your computer still recognizes it, you may be in a soft-brick. Try flashing your stock ROM onto your LG L70 and wipe caches.

Hold volume down + power for 15 seconds, hold it even longer to try to get into fastboot mode. Was the battery low? Maybe you need to charge the phone up.
