[Upgrading, Modifying and Unlocking] banannq:
yes, delphi is much like pascal

i know it's not that hard if you mean the structure. i just don't know how to start. in fact i got myself evc yesterday, after what you say i'll take good lok at it as soon as i prepare some room on my HD.

Delphi does well with windows api - as far as i can tell, i played with theese a bit so it shouldn't be hard to catch up when starting with c++. other thing is i never did dll, although i know how it works in general, i also used other peoples dll's in my programs. will do i hope. also, Rudegar provided us with good tutorial/example on today dlls, so i hope i'll be able to expand it. the only thing, i'm a bit anxious. you say evc is good for starters? ok, going to give it a try.

what a week, four days, four new RAD environments already:)
[Upgrading, Modifying and Unlocking] Rudegar:
delphi is object pascal which is an extention of pascal like c++ is of c

c programs should compile without any problems in c++

Hi,

I saw a way to develop today plugins in .net : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppcgen/html/TodayScrn.asp?_r=1

I did not try and I guess it will slow down the device as .net is not very fast, but you can try...

Good luck ;)

THIS GUIDE IS ONLY FOR L90 D410, D405, D405n

​

First of all, This is not my original work. I am just sharing this GUIDE for easy Bootloader Unlocking and flashing Custom Recovery to L90.

Root Access required to Unlocking Bootloader and Flashing Recovery. If you are already rooted then go on, if not then down towelroot apk from https://towelroot.com/ and root your phone and install superuser from play store.

DEVICES FLASHED WITH THIS GUIDE AND TESTED OK: LG L90 (D410)

Follow this guide step by step :-

1. Download and extract L90_D4##_v10x_aboot.zip

(# = your device model, x = version of stock firmware)

and any custom recovery zip you want to flash from the attachments below this post to external sd card (aboot.bin should be on external sd (/storage/external_SD/aboot.bin) , not in any other folder.

2. Download and install terminal from play store and run it.

3. Now type following commands in terminal :-

(Grant superuse permission to terminal after typing "SU" command)

4. Exit terminal, download and install Flashify from play store. Run it and grant root access.

5. Tap on Recovery image > chose a file > select recovery.img file

6. Tap on Yup!

That's it you are done

HOW TO BOOT INTO RECOVERY PRESSING VOLUME AND POWER KEY

You can reboot to recovery via flashify app or following key combination: -

Power of your phone press both Volume Down + Power Button same time, As soon as the LG logo appears release both buttons and immediately press and hold same buttons (Volume Down+Power) again. Now Factory data reset screen will appear saying "Erase all user data & restore default settings?". Use volume down key to select "Yes" and press power button to confirm and now you should be in recovery. (Caution: Don't try this while stock recovery installed or it will erase all your data)

In case of brick or want to flash stock firmware, please follow this guide :

I used evoname's autopatcher, does this aboot work for all variants from v10a to v10d? I thought they all had their separate aboots.

.

anyways the aboot patch works, tested on my d410 v10b

is "dd if=/storage/external_SD/aboot.binde" a typo?

I advice that users first enable fastboot and make backup before doing this.

Please help!!!!

Hi guys,

I've bricked my D415 by flashing the aboot.bin for the D410.

Now my device doesn't turn on, even when I connect the charger. However when I connect the charger cable with the battery out, the phone turnson and shows a signal to put battery back.

Is there any way to solve this issue? Maybe by reflashing the aboot.bin (I backed it up before).........

Help plz... :(

[LG Optimus L90] shinobisoft:
If ADB still recognizes your device, then yes, flash back your original aboot image. Otherwise, it's KDZ flash. Did you zero out your laf partition to enable fastboot? If so, put device in fastboot mode and flash aboot backup with

fastboot flash aboot "path/to/aboot.bin"
[LG Optimus L90] VR25:
My device is completely dead...

It doesn't turn on.

No fastboot, no download mode, no adb, no life... :(

But when I connect the usb without the battery, the phone lights up and shows a missing battery icon. Only in that situation. other things do not work, the phone is "The Walking Dead, Last Season"

I think that the aboot is the bootloader of everything... but the question is "why does the phone show the missing battery icon, and then when I put the battery back it doesn't show anything...? No charging, [nothing].

Bricked....?

Hello all, I think I bricked my phone (lgl90 D410) I followed instruction from first post , also this is not the first time I do something like this on a phone.

Everything seamed to be fine during the process, but when I tried to boot in recovery the phone wont start at all, the only sign of "life" is when I pull out the battery and plug in the USB cable it shows maybe a warning that the battery is missing, that is all :(((((,.

Can some one help me, can I fix this or I should go with warranty ? Thank you in advance !

[LG Optimus L90] k2wl:
i have done it a little different way that OP said. on my INDIAN D410

here is what i have done.

1.i have rooted with towelroot and install "supersu,busybox and quick boot "from playstore

2.enabled developer settings in about phone.

3.go to developer settings and enabled usb debugging

4.connect phone to pc in MTP mode

5.open terminal on my ubuntu(you can use windows with adb installed)

6.given following commands

(accept the rsa key prompt if appears)

(grand super user request)

(after reboot go to adb shell again with su propmt)

(you can use cwm.img or twrp.img from quarx's cm11 thread)

in quick boot >>>click recovery>>grant super user

and you are in recovery.

i think this is a easy way as no one has to type commands on mobile which is cubbersome and liitle uneasy.

here you can copy paste if you want...:)
[LG Optimus L90] gdjindal:
Thanks for suggestion buddy,

I am aware of this method. You are just using a PC for hole process, but what I am thinking is, that not every L90 user can afford a PC (in INDIA) :( , but can afford Terminal app for free from play store

Problem is that you flashed wrong version of aboot.bin zip file unto your device. You can only flash v10d aboot.bin on firmware v10d and no other.

Your phone cannot go into download mode even if you have kdz file and the situation seems hopeless. However,the phone can be restored?. I restored one recently.
[LG Optimus L90] Lazgeor:
Don't worry, I have restored it now. I'm a actually typing this from my phone. However, the solution I found in order to unbrick it involved a low level format and that deleted my IMEI too. Now I need to root it in order to restore the IMEI using QPST and some other programs I found on another threat. Anyway, thank you for your response :)

If you plan to install a custom ROM then you can use any aboot to flash TWRP then install ROM (I'd recommend to flash a full bootstack fir your phobe first, Lollipop if you flash CM12 or 13). If you want to stay on stock 10f then you are out of luck: backup your aboot to a safe place and try latest unlock. Besides the wrong info in phone settings you may not have any side effects...
[LG Optimus L90] sidhhu:

Backup of stock aboot is explained here:

If there is a stock ROM for D410 that's for another country it may work for you, buy mayor may not support your language or 2G/3G settings for your country, you'll have to test it. You can always go back using LG Flash Tool if download mode is available.

Hello. Really wanted to get CM13 on my D405n. Tried a lot of times this tutorial. Soft bricked my phone everytime i tried (but found a way to bring him back to life).

So, after the terminal step, and flashify (using twrp provided by app) i choose to boot on recovery mode. That's when phone gets soft bricked, and don't give any sinal of life. When i connect to computer only shows - removable disk - with 43 Mb of space, containing 2 folders.

If anyone can help, it would be spetacular. Thanks.

PS: If anyone wants to know how to unbrick, i can try to help.
[LG Optimus L90] lfom:

What is your stock ROM ver. & which aboot file are you using??:confused:

these hard bricks happen due to wrong aboot files flashing and not by recovery!!:good:
[LG Optimus L90] afrsantos.89:
Hello. I think i get the method from XDA. Will check it later.

Really think the problem is between the version of aboot file and the Stock Rom. My stock ROM is V30a (from the LG Support Tool, that i use to unbrick flash from upgrade error option) but i only found V10a aboot files.

Now, i have two questions:

1 - Is it possible to get the aboot file for v30a? Never found it.

2 - If i can't get the correct version of aboot file, is it possible to donwgrade to the correct version of aboot file?

Surprisingly, from the last time that bricked the device, it's now showing a different kind of Brick where i can see in the device manager "QHSUSB_BULK" and doesn't show anymore as a storage device. Do you know how to unbrick from this? I found a way but i guess it needs to be done from a 64bits OS. Will try it later.

Thanks for your help. I am going through this because i would love to try CM13
[LG Optimus L90] Tejas tedi:
How you got v30 ??? on which android ver it is

for global it is v20 only!!!

AFTER UNBRICK TRY THIS!!!

1.Flash this KDZ ver https://www.androidfilehost.com/?fid=24052804347761023

2.Root it with some method!!!

3.Use this aboot to unlock bootloader http://xdaforums.com/attachment.php?attachmentid=2904709&d=1408518903

if it succeed THEN FLASH TWRP RECOVERY!!

Then flash your CM13!!!:laugh:
[LG Optimus L90] afrsantos.89:
Meanwhile, the last brick i think it was a hardbrick (QDloader 9008). Computer only recognizes phone as QSHUSB_BULK. But found some tutorials to fix it (already did b2b lg tool sucessfully, but don't know the next steps :( ).

I think you're right about the version of the LG ROM, probably v20a.

As soon as i can unbrick the phone, i wil try the steps you mentioned, anda will post news of the process.

Thanks a lot :) i should came here before trying this by myself.
[LG Optimus L90] afrsantos.89:
Hello.

So, i could get the phone unbricked using files from another thread (dumbass), but i think that it was missing the

sbl1.mbn

file, so i got it from your instructions. I think this could have created problems, because now i can't flash your kdz file because lg flash tool crashes when upgrading to device. And i also see that initially, lg support tool recognizes my device wrong as D41010a.

Now, my phone just let me do 3 things:

- hard reset by vol down + power

- download mode by pressing vol up before inserting usb cable

- turn on anda stay on first screen LG.

If anyone could help, i would be grateful.

thanks
[LG Optimus L90] Tejas tedi:
NOW YOU CANT FLASH KDZ AHH???

and have you tried to hard reset

i think the kdz is not flashed properly

and for wrong device in the support tool you would have used d410 variants file while unbricking!!!
[LG Optimus L90] afrsantos.89:
Yes, tried a lot of times the hard reset (Power+Vol down), but always get nothing different.

Yes, probably flashed the wrong files, with exception for sbl1 that i got from the files you mentioned (because didn't have).

do you have any sugestion? maybe try brick again onto QHSUSB_BULK, to do the procedure with all files you mentioned?

Meanwhile, i'm trying every possible way to correctly flash kdz.
[LG Optimus L90] Tejas tedi:
Which method did you use to unbrick???
[LG Optimus L90] afrsantos.89:
I used this method (didn't need to do the 1st Part).

But i think i got the files to this method from another post (i can search again, if it helps), only used sbl1.mbn file from the upper link because it was missing from the first download.

does that affect my aboot choice?

or did I had a different aboot before?
