Please help! Need LM-V405UA1 At&t full backup - LG V40 Questions & Answers

please somebody help me

Not sure you're going to find it. Att prevents lg from publishing their specific varriant of the rom. You can use the unlocked rom which does support all of the att bands for the v40 though.

Phone was SIM locked by Att. Аll the Att's apps were disabled, so there was no message about the lock. Then phone crossflashed with US open. Now there is simply no message about entering the unlock code.

[Q] AT&T XT1058 can i flash it to a generic rom?

Hi, I got an AT&T XT1058 from ebay. I'm in teh UK so I'd really like to flash it with a stock UK ROM. I've had a look on here and with the huge amount of info I can't figure out if this is possible and which rom to use. it's 4.4.2 that's on the phone at teh moment which i believe can't be downgraded or unlocked easily, is that right?
any help would be greatly appreciated
cheers
To flash any Rom besides the Stock, Signed Moto ROM for your carrier and model X, you need to unlock the bootloader.
While Moto doesn't give out the Bootloader Unlock Code for the ATT USA XT1058, since you have 4.4.2 on it still, you should be able to use Sunshine to unlock the bootloader. (NOTE: please boot into fastboot/bootloader on the phone, and verify the version on the 2nd line is 30.B4 which is correct for 4.4.2).
Once you use sunshine, you can flash 3rd party recoveries, roms, etc.
While I have NOT done it, I've seen posts of ATT US Xt1058 owners flashing with Parts of the XT1053 rom to remove bloat, etc. (flashing the modems will likely change which wireless bands the phone can connect to). I do not advise flashing another carrier's rom. It could get messy, especially around UPDATE time. And I've seen some lose Cellular and WIFI flashing the wrong modem files.
One final thing. The ATT US XT1058 is SIM/Carrier locked too. So in order to use a non-ATT SIM in it you'll need to obtain a SIM unlock code. You should be able to get this from any web site selling unlock codes on the internet.

To unlock the bootloader on the ATT XT1058 Moto X, there are only two possible ways..
The China Middleman thread (in the general section), although he only has codes for certain date range of phones (depends on the Assembly Date of your phone), BUT he has recently stopped responding again. There is no telling if/when it will start up again
Sunshine, which doesn't work with 4.4.4. However you can always try it since it wont charge you if it doesn't work. (i.e. it checks your phone, if it will work, if wont, it tells you and exits without charging you).
4.4.4 can't be temp rooted either.
So you are pretty much stuck stock ATT, and then just get it sim unlocked to use it with your carrier.

thanks for the reply. I guess i'll give the china middleman a try. I'd really like to get rid of the ATT address book, the fact that it perpetually shows as 4g connection and have the phone speak to me in a not american accent!
cheers

I'm on Rogers xt1058 (16GB)
Is there any way (assuming I can unlock the BL) to get developer edition ROM?

For the Rogers XT1058, Moto does offer the Bootloader Unlock code for free from their web site -> https://motorola-global-portal.cust...e/bootloader/unlock-your-device-a/action/auth it will void your warranty
The GSM Dev Edtion is the XT1053. It has different radio/modem files, its hardware supports different bands (less LTE bands). I never recommend flashing another model's ROM as we have seen loss of cellular in some cases, where even flashing the original firmware back didn't fix.
Once you unlock your bootloader and root, you can remove and freeze any bloat on the phone (freezing is preferred because the next OTA might require it to be there).

Only if you can't unlock your boot loader. But as I said, moto does give out the unlock codes on their web site for the Rogers xt1058
Also, without unlocking the boot loader, you can only flash the rom for your phone model and its carrier branding.
I see
Thank you for the answers
I knew the second part, was not sure about the first one.

[Q] Switching to AT&T

Hey,
I just recently moved to the USA and I am trying to set up my Note 3 to work with AT&T but I'm not sure how to do that.
The phone I currently have is a Rogers Galaxy Note 3 N900W8 (Already knox 0x1), and I'm curious what I need to do to make it work with my AT&T sim card.
I was hoping to stick to ViSiOn-X but from what I can see that is not available for AT&T, so I'll probably just stick with the stock ROM, whichever that is.
Though, I do still have a phone plan in Canada and would like to switch between the sim cards so that I can check my voicemail if at all possible.
Is it possible to set up my phone to work with both Rogers Canada and AT&T USA? Or am I required to purchase a factory unlocked phone to do that?
If it is possible, how?

You need a factory unlock so you can switch carriers now as for the rom I'm not sure if the rom will work on AT&T, you should check the rom forum an see if other AT&T users used it an if don't already know the Model for AT&T is SM-N900A, also you could always try the rom once you get an sim unlock, an try it with that rom but if it don't work flash a rom that you kno will work

Ive got my phone unlocked now, but I think there may be some issues with the ROM. When I first unlocked it I was getting the 4G connection to AT&T. Now I just have the regular phone connection, no 4G. Data is on.

Can it work on the AT&T version of the lg v40?

Just got my LG V40. Is it better off to cross flash it? Can I do anything else to it?

So I just got my sprint V40, Model Number LM-V405UA
android version : 9
Android Security Patch: March 1st 2020
And the software version is : V405U20d
Are these all up to date on my model?
______________________________________________
2nd question
What exactly is the benefit of cross flashing the phone with US unlocked KDZ or ATT Unlocked or any other KDZ?
What do you gain from doing it?
is there anything else I can do with my phone to improve it?
1) Yes.
2) & 3) More bands available to you/better compatibility for when you decide to leave Sprint for another carrier (make sure the phone is SIM unlocked first!), plus the ability to connect to more towers if you travel to other countries. Less Sprint bloatware.
4) Unlock bootloader and root device. Take full control of the tech you own!

I dont actually have sprint, I have Tracfone as my carrier and use the AT&T sim card
which KDZ would be best to use? I looked at LG Firmware and saw US Cellular but there's also the US unlocked one too
The only information i've seen about rooting and unlocking the bootloader is to contact someone that has a octoplus box

If you crossflash use the US unlocked.
Look here for unlocking the bootloader.
Once you've done that, rooting is as simple as using TWRP to load Magisk.

Get the US unlocked KDZ. I also had the Sprint model. Crossflashing to the US unlocked allowed me to use wifi calling and the additional bands for T-mobile.

Is it possible to unlock LG V40 T-Mobile US for use in UK?

Hello. I was iterested in getting a second-hand V40 which happens to be the US T-Mobile version. But i want to use it here in the UK. I've checked the specs and it seems to support all the band numbers which my carrier uses. But I have read that the T-Mobile V40s are somewhat restricted and it is not possible to root or crossflash. Does anyone know if it is possible to unlock for UK use? And if so, how?
Many thanks
What do you mean? Unlock is sum unlocking, root is root, cross flash is cross flash. Dont tell me you got the word unlock mixed up.
Rooting and crossflashing will not unlock the sim carrier for you to use as youll need to unlock before crossflashing. Also why not just go buy an unlocked variant as LG also has the US unlocked version. every manufacturer's unlocked version will always have more radio bands.
