[GUIDE] Unlock Bootloader and Flash Custom Recovery L90 D410, D405n, D405 [CWM][TWR]

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.
I have tested this method myself and it is working perfectly for me, but it is also possible that it might not work for you for some reasons, so don't panic, just post your problem or whatever error you are facing (please attach screenshot if possible). I or other thread members will try to troubleshoot it. After resolving the problem I'll update this post, so that other members do not face such problem again.

Here is also another method to unlock bootloder using ADB on PC by @SubliemeSiem
Guide to unlocking the bootloader on the L90 using ADB

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.

Does this work on D405 v10b?

Only for D410

another typo :
"of=/v/block/platform/msm_sdcc.1/by-name/aboot"
the /v/ is supposed to be /dev/ right?

It was typing error crosswire, thanks for correcting me

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...

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
Code:
fastboot flash aboot "path/to/aboot.bin"

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].

Worked great on my new d410, thanks. I noticed cwm has no backup to ext sdcard. Its this a phone limitation or its from cwm recovery?, so I'll switch to twrp instead. Cus phone memory is too small for my full cwm backup

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 !

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

Stuck in a pickle ( D415 fastboot)

Hey guys long time personal device modder and lurker here, I've seem to have bricked my girlfriends phone, and she is currently not very pleased.
I attempted to unlocked the boot loader for her D415
from this tutorial here http://forum.xda-developers.com/lg-l90/general/guide-unlock-bootloader-t-mobile-l90-t2836457.
did the first half of the guide ( adb ), I wasnt able to get reach fastboot from lack of fastboot drivers, but after reading another thread turns out her d415 was unlocked already. I rooted the phone with towelroot, installed TWRP from I think rom manager, booted into recovery from terminal emulator, made a backup of the phone using TWRP and installed cyanogenmod 11.
Now everything worked great with the phone, but she wanted Gapps. When I installed Gapps from TWRP half of the Gapps werent there ( the play store was missing ) , and a google plus notification repeatably kept popping up. So I decided to restore the phone with the backup of the phone I made earlier and reinstall cyanogenmod. Once the restore was complete it was booted into fastboot. At first her phone wasn't being recognized, I found the drivers for fastboot, on this guide here http://forum.xda-developers.com/lg-l90/general/guide-fastboot-l90-d415-t2827825. I can communicate with my phone from fastboot but that's it. I tried using fastboot to install the cyanogenmod and stock rom but I got a 'error: update package has no android-info.txt or android-product.txt" from each rom
So any help would be appreciated! Sorry for the long post, I didnt wanna leave out any details that could help!

I don't think I can enter recovery by holding down buttons on this phone, I think the only way I could reach it is from a terminal emulator or TWRP manager? So what would flashing a recovery do ? because wouldnt I still be in flashboot?
Sorry only being stuck in flashboot is weird.

BOOT problem

99% SOLVED
Hello all.
EDIT 070117 Partially SOLVED - after 0% battery is possible enter to FastBoot, but problem with TWRP or Unbrick stay...
EDIT 2 only Revolution recovery is going, but no efect... still trying install OS
I tried install Revolution ROM on my Huawei P9 lite (1 SIM card model for Europe - LN21), I unlocked BOOTloader, flash recoveries and ROMs, but after last install phone reboot ONLY in "wait for boot" mode... No acces to recoveries and FASTBOOT mode.....
Any ideas?
Thanks..
EDIT 10 01 2017
After about 100 reflashing everything inside OS works only 1 solution (99%) - i was on broke Nougat, nothing work correctly....
go to fastboot (turn off, hold down volume and plug USB - PC)
1. flash twrp beta 9 from BadWolf
2. Flash this zip http://forum.xda-developers.com/atta...1&d=1481994704
IN CASE OF UNABLE MOUNT ANY PARTITION - USE product v_3 (twrp restore by Badwolf)....
3. Put the MM UPDATE.APP in the DLOAD folder on EXTERNAL SDCARD (it is possible use internal storage, i used VNS-L21XXXXX120)
4. Install it using the 3 button method (dload method) but sometimes work only + volume and power on
5. Factory reset
In case - decryption code need, only write anything and ask on revert data by eRecovery....
Now everything works correctly , ONLY FASTBOOT DONT WORK yet....
PS SORRY for terrible english!
6. DONE!!

First make sure you are using the right version for your build.. After you install it via fastboot, from there go to the recovery menu, up, down volume. When in there wipe data.. Some say factory reset, but I wiped data which did the same thing, and now it works.

Question IDK Redmi 10S

Hi there.
I wanted to root a Redmi 10S device. Bootloader was also opened. The flash went during fastboot mode, then after the fastboot reboot command, the device restarted, but it only shows "Redmi" and the word android at the bottom. I tried to access recovery and fastboot mode, but powr+volD only restarts the device and only the Redmi inscription is visible.
I don't know what they call this state in which the device is.
If there is a suitable link on the forum, I would appreciate it.

Hi there!
What did you flash excatly?
I mean, did you flash the whole phone, or just a patched boot image?

Then, you don't have to flash the whole phone again, just flash back the original image, and try rooting with twrp and magisk zip file (rename the apk file from magisk.apk to magisk.zip, and then flash it in twrp)
If you can't install twrp, or something went wrong, take a full backup from your phone (like using google's backup service, and Miui backup--> it 'll save the backup to internal storage/miui/backup/AllBackup) and then ypu can reflash the phone with mi flash tool, but don't lock the bootloader back, and after flash, you shuold enable oem unlock in developer settings.
One quick question:
Did you enable oem unlocking in developer settings, before trying to flash the modified image?

yepp, enable oem unlock. But fastbootmode is required for all operations. But fastboot mode doesn't work.

What do you mean it doesn't work?
Can't enter into fastboot mode?

Can't enter fastboot mode. The device only shows "Redmi" lettering. If fatboot worked, I could have done it already. power+volume down, the device just restarts and shows "redmi".

Hmm..
And if you holding the volD and power buttons together for a longer time?
Like a min, or sth
I had a similar situation, but after a few tries it went into fastboot mode

it just restarts, as long as I press and hold volume down+power, if I don't press it, it just shows the redmi text

Hi there the forgive my on my bad english and text.
The Only thing u can do is restoring the firmware by using brom mode, Look it up or follow the steps i'll give u....
First keep in mind brom works best Without the batary conected . So remove the thin cover plate at the back u can loosen it with heat , after removing the cover move all screws and remove the housing so u can disconect the batary at the mainboard .
Next u will have to install the Vcom drivers according your chipset mediatek etc.
For the Vcom drivers and install of it u can follow https://www.hovatek.com/forum/thread-16640.html
U must download or allready have a firmware file in fastboot format , Open up SP Flash tool and go to optionsd and select connection, click the w/o battery option and close it. Open your scatter file and than click on download . Insert your phone wile holding your volume down or up , with my device a redmi note 10s it was the up and down to getter for it was flashing the rom. this should flash your device back with a working fastboot and working rom.
Hope u will succeed...

Yep, this guy here 's got the point. If you can't flash with sp flash tool because auth fail, there's a method to bypass it.
You can find the tutorial here: https://www.getdroidtips.com/bypass-mediateks-sp-flash-tool-authentication-protection/
I also got some help from this guy's post, many thanks to him too.

Let us know how it's going with it! ;D

I can unbrick the device at any time. There is another problem. An incorrect boot file is probably being copied. After TWRP you will never enter android again. But TWRP also only loads up to the subtitle. I tried a lot of methods. Now I will try google p ex. android and make it root.
But, if someone can recommend a device intended for gaming, but easy to root, then I will buy one

If you can root it easily, then the expensive one is good for me! Normal root was not available for typical gamer phones for years. If I buy something for which root may not be available, then I'm wasting my money...
