Help with D405n bootloader and stock recovery
Ok, so I am completely new to the rooting, bootloader and recovery community, and Android in general. I was trying to unlock my bootloader, following an XDA tutorial, on how to do it on all "LG L90 varients". It was an old post, from 2014. I hard bricked my phone, waited a long time for someone to be able to help, and thankfully someone referred me to a very helpful post on how to unbrick LG L90's. So now I am unbricked, I rerooted my phone, and trying to install the Cyanogen ROM. I believe my phone still has the stock recovery and the bootloader is locked. After about an hour of searching, I found nothing helpful. So I want to know if anyone can help me. I want to unlock my bootloader and change my recovery. I don't know what I have to do first, and don't know how. Here is some info on my phone which may be helpful.
Android version: 5.0.2 (Lollipop)
Kernal version: 3.4.0+
Software version: V20a-OP1-SI
LG D405n L90
Firmware: VUK/Virgin Mobile (United Kingdom) V20a
Please reply in a noob friendly way, so I understand. Thank you.
Check this link for instructions for unlock boot loader and install custom recovery but don't use its files because you are in version 20a (android 5.02) and they maybe outdated:

Go here for updated custom recovery and check some posts down for aboot for 20a

Don't forget to read well the posts and don't make any mistake or you may brick your phone again.
Good luck [emoji1]

I saw it before, which is how I bricked my phone, using the wrong version. However I found a v20a download on some cyanmod.pl forum, went with Cyanogen, hated it so went back to stock, lol. Anyway, thank you for the help.
Why the CM hate?
Can you pls share why did you hate it? Currently I am in process of figuring out how get custom rom on my d405n v20a, but from what you say, maybe I should stop trying. But I cannot imagine something can be worse than L90 Lollipop...

Hello! I would like to ask you for a favor. Could you pretty please explain to me how you unbricked your device the first time? I did the exact same mistake and used the wrong version in that post Now my device doesn't display anything, except when I plug it into the computer or to the charger without the battery on it. Also I see a 63,9 MB drive when I plug the phone into the pc. I believe you experienced the same things since we did the same mistake. So please help me, it's my only phone and I really want it back :crying: If it's a big and hard process, then just give me the links you used to find the instructions/solution. Thanks for your time and I count on you!

Hey, Lazgeor. I'm really sorry for the late reply. If you still have the same problem, here is the reply that I followed: http://forum.xda-developers.com/showpost.php?p=61808443&postcount=9
Make sure you have the right LOADER.img file. Take your battery out and whatever it says on the label is your phone model, if it's an LG L90 D410 then you can download the LOADER.img file from the reply, if not you can Google the right LOADER.img for your phone.
If you brick it even hard to where it only shows in Device Manager under "Ports (COM and LPT)" I can also show you what thread I followed. You loose everything when it gets bricked but you might be lucky if you had a gmail signed in with auto-sync on. It should recover most data such as app data, photos, etc.

Hello! Thanks for your reply I found that reply about a month ago as I was searching desperately to find a solution about my phone. Thankfully it worked and since then my phone has been working perfectly. However, my IMEI number became 0 after that tutorial, but I found a solution about that too in another post (after I asked for help first ). It's here for people who are wondering: http://forum.xda-developers.com/lg-l90/help/lost-imei-device-t3285130 Thanks for posting me this message. I may have fixed my problem but others have not and it will help them!

Hi all here is my dilemma concerning my personal DD, the phone was bought new in 2015-6 brand new and is currently on Android 7.0! The phone is in my opinion still very relevant and can be made even more so (if) I can update the whole firmware to the recent Note10 UI as seen elsewhere??
The trouble that I have experienced is trying to install TWRP via Odin? What happens, it recognises the file to be used, I set the parameters and start! It moves reasonable quickly then suddenly stops - No errors on the Pc/Odin page BUT the phone moves from the download mode in English to Chinese with Warning triangle and remains there until I reboot phone which starts up as normal??
I cannot get past this, and do Not know why the Change to Chinese that I do Not read or understand, so I have a few Pics but the 2 that I think are telling I will add if possible?
I found something in an overall search via the net, but this was the only one and this though Unclear in it self did Not assist me! Would I be correct in saying that this may be unique in that neither pictures or any where as this error arose hence why my possible struggles? Please can someone help in Solving this puzzle thank you.
I'm a Chinese student,my english is bad,and I can’t watch then forum all timeI，becauseI need vpn. flash xperia10ii‘s boot.img, then I turn on it .In start then Warning is white ，then turn green，finally it was dark，this Process just a few seconds。one more thing，my xperia10ii's BL was unlock.If someome know how to safe it,please help me,thank you very much.
我是一个中国的学生，我的英语并不好,因为我需要使用VPN，所以我无法一直查看这个论坛。我刷写了xoeria10ii的boot.img，然后开机。在一开始，它的警告是白色的，然后变绿，最后变黑，这个过程大概就几秒钟。还有一件事，我的xperia10ii已经解开了BL锁。如果有人知道如何救砖，请帮助我，非常感谢。
I just want it flash the official ROM
