Is it possible to change a locked d802 rom to a open d802 if i root and flash?

So basically turning a provider locked phone into the european open D802?
edit: another question:
If i do a nandroid backup of my stock LG rom, is it possible to just do a nandroid back up, install stock recovery and basically "lock" the phone without the hassle of having to go through the longer "unrooting" guide?
thanks in advance!

It should be enough to follow the "back to stock rom" thread http://forum.xda-developers.com/showthread.php?t=2432476 , this will change the current rom with a stock LG rom using LGs own tools.

Partially no, it flashes based on IMEI region. You want to flash a EUA KDZ. Then disable OTA.

I apologize for the lack of knowledge. Ive flashed all my phones so far sgs 1, nexus 4, galaxy nexus,htc one x and what confuses me about this phone the most is the kdz files.
My phone, for example, is a provider locked d802 - provider being www.a1.net
(Austria)
Now i followed the link you showed me but it only shows me open european d802 and some from germany files fir download. Would it be safe to flash those when reverting to stock considering i have a d802?
If i want to flash my provider's rom, how do i go on to acquiring those files ? Just incase of phone issues and i have to send my ohone in. Would it be as simple as flashing my stock nandroid backup, flashing stock recovery and typing fastboot oem lock in cmd ?
Im sorry for all those questions, while im quite confident i would get it done, i just like to acquire the basic understanding needed before i start anything.
Not to say i dont understand the effort put together by those who made the threads (how to flash/revert to stock etc.) But the threads to a certain degree are limited to just a simple how to when they could maybe use a little bit more detail.
Thanks in advance guys! Looking forward to rooting this thing

If by unlocked, you mean allow you to put any Sim card in it and it work, no I don't think there is a way to make that work. Roms deal with a totally different part of the phone than the carrier lock. If you mean boot loader unlock, that would specific to your phone model and flashing one from a different model could do nasty things to your phone. I would suggest finding the exact forum for your phone model (I.e. at lg g2, international g2 etc).
They should have all the info you need, and to carrier/Sim unlock your your phone to use on various providers- I would Google "Sim unlock *insert phone name here*) and read through til you find a site that will work out.
Edit* I just saw your provider, u "should" have an international version and you should be able to easily bootloader unlock, root and flash the phone. Be sure to read carefully before attempting anything though.

Oh.. So although im provider locked and own a d802 i basically still have the international version and therefor should follow the d802 international guides/should be able to flash d802 roms?? I really apologize if my questions have been stupid so far. Just i am very cautious. Thanks a bunch though.
But can you answer thr nandroid part (in bold text) ? Basically reverting to stock with nandroid backup, flashing stock recovry und locking the phone in fast boot. Is this doable on the g2? Thanks a lot once again appreciate it

If you unlock your boot loader and install a custom recovery like clockwork mod or teamwin recovery you can then make a nandroid of the exact stock ROM to restore back to. Relocking the boot loader is separate but usually fairly easily done. More often than not, the steps to relock the boot loader are laid out in the same thread to unlock it.
Be very careful, most of the time, once you start changing things you NEVER EVER want to accept an ota update from lg until you return EVERYTHING back to stock.
My recommendation would be unlock, install twrp and flash a custom ROM. That way you won't ever be asked to do an lg update, and most custom Roms end up being as stable or more so than the software that came on the device to begin with.
Or to return to total stock easier, most phones have a "factory" image that flashes in Odin or some other similar software meant for that device. It will erase everything, remove root and relock the phone all at once I believe. Just remember to read everything at least twice, and try to totally understand exactly what you are about to do.

I made a mess of my G4 plus

I'm not sure if this is going to end up as a fix or a cautionary tale, but here goes.
Was looking to root my g4, so I successfully unlocked the bootloader & installed TWRP using this method: http://forum.xda-developers.com/moto-g4-plus/how-to/guide-newbie-resource-thread-t3386584
Things were going pretty good there, but when I tried to install the SU image through TWRP, the phone wouldn't boot.
Naturally, I didn't do a backup of the stock state of the phone (BECAUSE I'M AN IDIOT!) so I figured, what the hell, might as well install cyanogen mod, and see what that's all about. There's a cyanogenmod beta for the G4+. It went on smooth through the TWRP installer and was behaving ok, but wouldn't see the SIM. I check the IMEI number and the phone does not have a value set, just blank space.
I then tried to re flash stock firmware on the phone, thinking that might restore the IMEI.
It was a bear to get on there, but I was pretty proud of myself when it booted.
Trouble is: still no IMEI number. Also no wifi and it can't see the SIM card (probably because no IMEI number).
So, I figured I'd go back to the cyanogenmod, and see if I could somehow trick it into an IMEI number, BUT! re-loading the firmware re-locked the bootloader.
I went through the unlock process at motorola again, but this time she won't unlock. The console is throwing me
Code:
...
(bootloader) invalid boot state
OKAY [ 0.005s]
.
So, from here, I don't know where to go. Try re-flashing cyanogenmod on it manually I guess, but I don't know if that will work with the bootloader perpetually locked.
Can anyone help me sort this out?
Please?

How did u flash the stock ROM? Did u flash the right one for your device.

I flashed the stock rom on manually from the terminal using fastboot. Evidently: it isn't the right version. After careful inspection, it seems like I loaded the Indian / Asian version, whereas my device is the Canadian version.
Unfortunately, the Canadian stock firmware is still listed as a work in progress.

And the file names are confusing as hell. My device model is xt1643 but my stock ROM doesn't even mention 1643 in the file name. What's your model number?

Did you turn on unlock bootloader option in Dev settings ?

W0000000ooooooooooooooooooHooooooo00000000000000000000000000!!!:victory:
We're back in business, kids!
Found the stock rom for the Canadian Retail build (not locked to carrier) here: https://mirrors.lolinet.com/firmware/moto/athene/official/RETCA/
It took forever to download, but once it showed up, I flashed it on with fastboot, fired 'er up, and it's the same old stock G4 with working wifi, that can see the SIM & Connect to the network, complete with IMEI number AND - I believe - an unlocked bootloader.... at least I get the unlocked bootloader warning screen on boot.
Varun: I saw your message when I was getting set to flash the firmware on and got set to put my palm through my head. You're right: it could have been just the switch in developer options. But I checked and it was on.
Maybe the mods can add that firmware to the big firmware download links post.
Now, you'd think that having just brought this thing back from the dead I'd leave well enough alone and quit fiddling with this thing, but...

Maybe the owner of the newbie thread should add a post with "take a backup through twrp"

No IMEI, bootloader locked, no root, no sim working

Hi,
I have an EU G7 L01, followed this guy's tutorial (http://ministryofsolutions.com/2016...ade-marshmallow-europe-asia.html#comment-2438) to update to marshmallow, replacing the "oeminfo" file with a turkish version, to trick the phone into updating. The new file had no IMEI in it, and after the update I was left with a locked bootloader, no root and no way to replace that file with my backup, to make the phone accept the sim card. From what I see, I'm either left with a small tablet or I have to replace the motherboard to make it work again.
Any other ideas would be appreciated.

To get your device to its original state, you need to downgrade to B340 of the Turkish firmware: http://download-c.huawei.com/download/downloadCenter?downloadId=74865&version=273720&siteCode=tr
Do a forced update with B340, root the device using Kingroot, replace your original oeminfo file, then install the official EU firmware.
If you really want to use marshmallow, then the only way will be to pay for your bootloader to be unlocked. On the source post, it clearly states that there was a problem with unlocking the bootloader, and HCU Client should be used to unlock it. The problem with that guide is that the bootloader unlock code only works a certain amount of tries before it becomes unusable, and the only way to replace your original oeminfo file is to have root, which is only possible on marshmallow with an unlocked bootloader.
I would suggest you let the guy who wrote the article know about your issue. Regardless of whether he stated that it is done at your own risk, he either needs to amend his article to that of the source, or remove it completely, as many people will not be able to pay $5 to get the bootloader unlock code.
Good luck!

So, are you saying that I will be able to root without unlocked bootloader?
Thx!

Help with LG V20 US996 demo unit unlocking boot loader failed at LG developer website

Hi, i hope this is the right forum, i am a noobie at LG flashing, been reading some, but it is a little confusing (coming from Oneplus One), so i bought an LG V20 - US996, and i thought i could unlock the bootloader via LG Developers website, so i started the process, install drivers, follow the instructions, etc. then when i submitted IMEI and device id i got an error, message, stating :your device (TEST_GPIN) does not support unlocking bootloader", i emailed LG with the question but still no answer, so i did a little research and found out that my phone is a demo unit or something like it. on the inside sticker it says "not for sale" the model on the sticker is US996. i have attached some screens that show software versions etc.
so basically i would like to know if anyone knows if i am out of luck and cant unlock the bootloader to flash twrp and root, or if it can be done, and point me in the right direction, any help will be greatly appreciated.
i obviously would not want to brick my device, but am willing to try to unlock if possible.
thanks.

That's very interesting. Wondering if that's the model the debug bootloader was pulled from to root the US carrier v20's. I'm not an expert in this but have you tried to flash the us99610f (Dec 1 2016 sec patch) kdz using LG UP. That should put you on official LG firmware that is still rootable. The kdz will flash every piece of firmware getting you off of that demo firmware. From there you could try to unlock the bootloader again using LGs website, or worst case use dirtysanta to root the phone if you wish. There's a hacked lgup thread somewhere in the guide section that should do the trick.

thanks toastyp, i will download 10f, and look for the hacked lgup.

thanks guys, i used LGUP from Prowler_gr thread https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222/page8 Thanks by the way.
downloaded 10f, and flashed with LGUP, no i have a fully working US996 (not demo version) at US99610f, i will keep reading so i can do the bootloader unlock and root.
thanks again for your help

Glad everything worked for you. I would try to root using LGs official unlock.bin method as it will be the easiest way to root the phone. Plus you get to keep your stock bootloader which is potentially helpful in the event LG implements ARB on the us996. If it still doesn't work you can try the dirty elf thread. I believe it's the dirtysanta method for the us996. This process will flash a debug bootloader with full fastboot commands that is unlocked. From there you can flash twrp normally.

thanks toastyp, LG official unlock still not working, as i guess the IMEI is still recognized as from a demo unit, i will try dirty elf method, might take a while since my home pc just died (mobo or cpu) anyway , as soon as i can i will try it.
thanks.

Is Cricket LG V35 bootloader unlockable?

If yes, the phone must be rootable. Is Lineage OS 16 support this phone?
I have done some researches on this forum but couldn't find an exact answer.
Thanks.

From what I've read and heard, no. It seems like the carrier-branded phones and Amazon phones are far less likely to be able to unlock the bootloader in order to root or flash different firmwares, but on different models some people have had luck performing "Frankenstein" flashes by temporarily flashing a different firmware using a hacked version of LGUP, performing the bootloader unlock, and then flashing back to the original. You don't want to flash a KDZ to go back to the original firmware from what I've gathered though as it could relock the bootloader -you'd need to find a flashable ZIP file or something that has all of the firmware and use TWRP to flash back to the normal firmware. You might have to use LGUP to flash some modem firmware and such back, but those guys will be able to better explain the situation than I would. I considered doing this with My LG V30+ H932 using lafexploit but decided that it was too much work for not enough reward and just stuck with stock firmware. Honestly as long as PDANet/FoxFi still works in non-root mode there's not much of an incentive for me to unlock the BL since I might lose the ability to pay with Android Pay or some other NFC payment apps.
