Question about my device!!

I don't know how strict people are about "searching" things before posting on the forums, but I rather get yelled at by some nerd on the internet, than to have my $350 device screwed over because I followed the wrong tutorial. Anyways here are my questions:
1) I bought this device from someone brand new, and it came out of the box configured to work with Windmobile, but I was able to get my FIDO SIM card to work by simply inputting it into the device. So does this mean that my device is already unlocked?
2) I still have the old 2.2 version on my phone, and I want the new version (2.3), but since I cannot update the OS from the device itself, I don't know what method I should follow from my computer, also I am afraid that I might lose my unlock (if it is) with the update.
Please link me to the proper tutorial, or give me some insight on my problem, Thank you.

Optimus L90 D405n: How Do I Unlock Bootloader?

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loader and install custom recovery but don't use its files because you are in version 20a (android 5.02) and they maybe outdated:
http://forum.xda-developers.com/showthread.php?t=2839690
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!

Look buddy I'm sorry this happened to you. Part of the reason I gave this cell away when I unbricked it was that the very first te it bricked it was bricked 120 days. Is all I can suggest is that you try not to panic an possibly delete system. It's similar to format data. Then try an make a clean start with the unbricking tool. My ex still uses it every day with zero probs an I think it may be an EU rom. These cells are natouriously difficult to customise. I hope you unbrick it soon. An I am sorry there are so many unsympathetic people on XDA who would rather say how ignorant or dumb you are than try an help. I refuse to be like that now. I am just a humble forklift driver. We cannot all be computer experts or write code or roms for cellphones.
Take your time an try an erase the cell in case something you are trying to hold onto is preventing unbricking?
I lost everything on my cell an only had it 2 days when it happened to me. You may lose your data. But erasing might help the unbrick tool work
Good luck. An breathe ok

MDM error, tablet T713 stuck on bootloop.

Hello everyone,
I have my tablet SM-T713 which finds itself completely blocked following a dumpling on my part:
I had activated a software which prevented the installation of software etc on the tab and wanting to simply reset, I had the ingenious idea of ​​making a Wipe data and attempted an installation of a full firmware via Odin above .
Fatal error ! Unable to write on it (MDM) and I find myself in bootloop without the possibility of writing on it or anything.
I tried the TWRP flash without success, I cannot try in ADB or SD : refused.
Is there a tiny hope or can I use it freezbie?
Thank you really much by advance.
Jonathan

Hey,
i have a question: can i use a full nand erase on Odin ? Maybe it's the good solution to repair my tablet?
Thank you !

I check it on the web and i don't find it for T713 Samsung.

Well I don't know how to build it (yet?) but as I'm interested to know as well, I've asked for how-to on that specific page.
Downloaded a stock T713 ROM and unpacked it.
It contains .mbn files but no .edf I can't identify all what the .mbn are for, if these would be sufficient or more/others are needed.
And of course don't know if the found ones could usefully be flashed with the QPST.
Hope the guy from that page will give positive answers.

The guy wrote an answer but not helpful at all:
<Hi. In case of Samsung devices, the only thing that will work is the Odin program. It’s hard to see a Samsung device getting hard bricked, just because Samsung has all those critical partitions blocked from being flashed. If you ever come across a soft-brick, you can just use Frija to download the latest Odin-flashable firmware and push it through Odin.>
So sorry.

Question Help about flashing Oxygen OS to Chinese Oneplus 10 Pro

I know that there are so many threads about this, but in every thread everyone is talking different.
I want to just know, which is the tested method to flash European ROM to Chinese phone?
I also dont have a proper link for european rom ( I have seen some people flashing Indian rom and what is difference between indian and european?)
So lads please help me, I dont want to brick my phone, because there are no OP support team near my country. So it would be a garbage.

By personal experience, don't do that.
My phone is just bricked from just trying to flash the same rom again.
I've always did on my htc, xiaomi, samsung and many others and OnePLus 10 pro was the first one to give me problem. If you get in a state that you need to run fastboot flashing unlock_critical and for some reason your device reset then it's dead with no chance to recover.
There is no tool available to us that can recover from that. The phone don't turn on screen, it's not recognized by the computer and even on the charger it just don't turn on. So completely dead.
The best way is to just buy the model NE2213, that comes with a global rom.

It is too late, cause I have bought chinese version and waiting to delivery.
Also there is no chance me to leave this ColorOS. So I will somehow flash or sell this phone

Yes I have seen this and much more posts about flashing.
Someone was lucky and made it, someone was not lucky and bricked phone...
Wish i have seen these failures before I buy phone

Get Fastboot Enhanced & files needed to access adb/fastboot from computer. Unlock Bootloader. Download the OOS ROM you want then extract the file you need for Fastboot Enhanced. Make sure no cow files exist on device with Fastboot Enhanced and then if all checks out you flash.
I've kept this very vague because like you've mentioned there are a few different tutorials explaining (including mine here: https://forum.xda-developers.com/t/...lobal-rom-region-change.4462591/post-87151395) but the basic steps I quickly explained should exist in them all. You'll just need to find one you can follow that makes the most sense to you!
I personally used NE2213 on my device that I converted from NE2210 and am using that device to reply to this thread. I am in Canada and this is Chinese Model OP10 Pro and all works fine on my end. Hopefully you can accomplish the same for yourself if this is your intention.

Should I use the link you pinned here? Is there a rom download link inside?
If you can help me ill be very glad.

If you can make sense of all the steps then go for it lol. My tutorial is more of a gathering of others work put together in a way that I hoped others could follow. I didn't want to re re re make another tutorial from scratch as your already seeing how confusing and inconsistent having so many guides can be!
I typically use Oxygen Updater on the PlayStore. Then in settings I'll do this (check photo). Then go back to the first page of application and you should see a download option (also check photo). Once you've downloaded the file just transfer it to the computer and you should be good to go. This is usually how I get the files...

Thanks so much, You made a great job lad.
Will try when I get a phone and I will let you know how it goes.

Just remember to keep reading over everything while you wait for your phone. Make sure to check everything over and over and just read all the threads here on XDA to get an understanding for what everyone else has done (the good and the bad) to ensure you yourself don't make any mistakes when the time comes.
I have the Chinese Model also and don't even understand one word let alone writing in the language but this is the phone I got and I gotta make it work so I can relate to your situation with buying it already and it being too late to change your mind lol.

my mind is blowing, everyday reading so much failures and bricked phones thats not good for mental health.
planned to go with your guide step by step and pray same time, maybe that helps lol
