Use an app like Flashify from Play Store to flash.
[LG Optimus L90] cavazte:
Flashed. As happened with the recoveries of this post, the phone shows a pink screen When I try to enter in recovery
[LG Optimus L90] shinobisoft:
Guess you'll be needing your own recovery too ;)
[LG Optimus L90] meer_mortal:
Have you unlocked your boot loader?

You may need a hacked aboot.bin
[LG Optimus L90] shinobisoft:
Yes he has. D400 unlocks like D415 apparently.
[LG Optimus L90] meer_mortal:
My best guess would be something wrong with his aboot.bin
[LG Optimus L90] shinobisoft:
Possibility. D415 doesn't need aboot.bin to unlock tho .
[LG Optimus L90] meer_mortal:
I don't know but those pink/purple screens were the same as what I got when I tried to flash a custom recovery without flashing a custom aboot.bin
[LG Optimus L90] cavazte:
Yes I have. Apparently this model does not need a modified aboot to unlock the bootloader.

[LG Optimus L90] meer_mortal:
Yes you're right you don't need modified aboot.bin to unlock you boot loader.

but you will to enter into recovery I'm almost certain.

But hey I could be wrong.

LGD405v10c

What's about the LGD405v10c abootb.bin? Can I use another one like the LGD410v10c or shall I do simething else???
[LG Optimus L90] shinobisoft:
I know you CANNOT use an aboot.bin or abootb.bin from another device. You will brick yours. I believe [MENTION=4646325]gdjindal[/MENTION] will know for sure. I think, from what I've read anyways, you will be alright using the latest version of abootb.bin for your device, even though you have a newer software version, but please don't quote me on that.
[LG Optimus L90] GrinningFerret:
Sorry for the double post.... I posted in the wrong thread and couldn't delete it. So you think I should take the LGD405v10b?
[LG Optimus L90] shinobisoft:
I believe you can, but I'd probably wait until someone who knows for sure gives an answer too. ;) I own the D415 which doesn't require any of this so I cannot say 100% for sure.
[LG Optimus L90] GrinningFerret:
Thank you nevertheless......
[LG Optimus L90] Skyrockcorp:
where i use to unlock and root d400h?
[LG Optimus L90] shinobisoft:
To my knowledge, there isn't a patch for any of the D400 variants. There may not be a need for a patch either. See this post.

From what I remember of what happened in that forum, you're bootloader unlocks like the D415 ( with fastboot oem unlock ) instead of needing to flash a patch aboot or abootb image. I could be wrong however so please don't quote me on that.
[LG Optimus L90] gdjindal:
I am not sure. But in my case, I have D410 and I flashed aboot.bin of V10C to newest V10D rom, it worked without any issue. So it must work in your case, but I am not sure. So try it on your own risk :fingers-crossed:
[LG Optimus L90] GrinningFerret:
OK, but what can I do, if it doesn't work and crash or brick?
[LG Optimus L90] gdjindal:
In case of crash, just follow my unbricking guide in sticky post :thumbup:
[LG Optimus L90] GrinningFerret:

Warranty

Thanks for your tutorial.

When i unlock my bootloader i lose my warranty? If i lose my warranty it is possible to relock the bootloader for reactivate my warranty and send him in reparation if it's necessary?

Cordially

Mathieu SERRA
[LG Optimus L90] wojtek267:
Yes, you loose warranty. Yes, you can relock bootloader by flashing stock rom
[LG Optimus L90] mathieu.0598:
And when i flash stock rom the warranty was reactivate? It's possible to save something in bootloader for reactivate warranty like with Sony?
[LG Optimus L90] wojtek267:
As far as I know (had samsung before) every action made in software is to be found in logs, but while flashing stock I saw a 'clear logs' button at one point. It might be that. Also, c'mon, we know these service guys are way too lazy and they don't check logs anyways (based on own expierience). So I would go for unlocking, there are nice things to do with L90 waiting
[LG Optimus L90] mathieu.0598:
You have a lg l90? If yes, what rom you use?

[LG Optimus L90] :
aboot or abootb @_@

Hi guys.

I can't find this explained anywhere in the thread and it's loading slow for me today so I've decided to post a question here.

I'm trying this on D405 10a EUR XX which I've already rooted easily with towelroot.

I've downloaded the aboot.zip file for 405 (not the 405n) in the OP. And unpacked it to find... abootb.bin!

The terminal step says:

"su

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

So... what gives? Should I rename abootb.bin from the OP to aboot.bin... before doing the terminal... or do this without renaming but simply change the terminal command to:

"su

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

?? Please help I don't want to mess up here.

hi to all guys, I would like to draw your attention to what happened to me, and possibly know how to restore.

I am owner of a lg l90 model d405n, wanting to unlock the bootloader I used an application that I would have to just unlock the bootloader and install a modified recovery.

Actually 'cell after this hack is pretty much dead, he would not turn either.

I started looking for various tools and various programs in vain, the cell showed no signs of life.

Then, now giving it up for lost, I tried to go for broke, I low-level formatted, and then with an application (umbrick) I could flesciare boot and everything else. Now the cell was lit and was also in mode 'upgrade download.

I downloaded the firmware of KDZ 405 and I tried to use flash tool but the procedure is always blocked to 2%, giving an error.

With the tool of 'LG blatantly that I discovered the phone was identified as d410, exhausted by the various trials do not go into port I wanted to download the KDZ model 410d and, as if by magic, flash tool worked! I installed the latest version and the phone works wonders!

So now I have a cell phone with firmware that is not his (among other things the 410d is also dual sim).

I would like to restore its system orifginale, that of the 405, but I'm afraid to do other **** ....

I hope someone can help me out

unfortunately being very inexperienced I would need a guide more ' detailed . Excuse my English ( Google translation )

[LG Optimus L90] lfom:
@up

You don't have su on Terminal. If you had the prompt would show "#" instead of "$".

Are you sure you granted Terminal superuser rights after using su? Check your superuser app to make sure it's granted. If no window appears when using su to grant superuser rights then you haven't rooted your L90 sucessfuly.

Edit: the screenshot shows you granted Terminal superuser rights. Remove it (don't block, just remove) and try again. If you don't see a dialog asking for grating rights when issuing su then something is wrong. Try another terminal app or use adb.

how i can do for root and unlock bootloader of a d405n lollipop SW version 20a?
[LG Optimus L90] lfom:
@up

You need to root first. If the one click tool doesn't work for you, you can use Kingroot and then a script to remove it, or unlock bootloader as described here, install recovery, open Kingroot and remove it from your phone then flash Superuser zip to enable root again.

Make sure you use the correct aboot for your device and ROM version when unlocking the bootloader.

[LG Optimus L90] lfom:
People with D410 v20a should take a look at the end of this thread:

http://xdaforums.com/showthread.php?t=2852917

A user reported that he used aboot from 20b and it worked. It should work, but may display the wrong version in the phone's software settings (shouldn't be a problem).

Just to be safe, I would upgrade to 20b and root again. If it is a problem because you don't want to flash a kdz and root again, then make a backup of your data and use 20b aboot. If it fails for some reason, get ready to flash 20b kdz.

Be careful everyone

This instructions are very dangerous to do if your device is updated. Even if you still use KitKat but you have done the first upgrade, then your version in not 10b but 10V or more. Do not assume that they may be the same thing because they so are not. I thought that same thing and used the 10b on my device, which is upgraded to Lollipop 5.0.2 and version V20a, and now my device is bricked and I don't know what to do. I also saw many people on other posts complaining that the did the same thing. So, if you're trying to unlock your bootloader/flash custom recovery, better search elsewhere. And I would advise you not to do it if you don't know what you're doing. It's very dangerous and you can lose your phone. And it's not really worth it. I'm actually 3 weeks without a phone now and I'm still searching for a solution. Just be very careful with these things.
