Hi guys. I bought an unlocked Sprint LG V40 (V405UA). I am from Argentina and it works perfect in my country with my SIM card, but the problem is that it has the Sprint firmware and it is in Android 8.1 and it won't update if i am not with Sprint contract i think. I'd like to have the stock global firmware and get OTA updates (Android pie at least). I see a page called "lg-firmwares.com" with all models firmwares and tutorials, but i am noob in this matter and i don't want to "brick" my phone or lose the unlocked condition. If i follow the "lg-firmwares.com" tutorial and flash the Android pie firmware for my model, can i brick my phone or lock it again? or it is secure and everythink will be ok?
Thanks.

Okay you have 3 ways to do this.
1st. If rooted/Unlocked Bootloader: https://forum.xda-developers.com/lg-v40/how-to/guide-crossflash-unlocked-pie-to-t3944359
2nd If rooted/Unlocked Bootloader: https://forum.xda-developers.com/lg-v40/how-to/guide-make-lg-v40-compatible-lgup-t3953120
3rd I personally haven't tried this yet: https://forum.xda-developers.com/lg-v40/development/lg-1-16-t3967559
With the 3rd one you should just simply be able to flash any KDZ but you should make sure it's compatible first.
But once you Crossflash no more OTA's you would have to download NEW KDZ and flash it over the one your on.

https://forum.xda-developers.com/lg-v40/how-to/guide-lgup-root-t3967858 This Guide i made should help you with your 3rd question. That we have seen no you shouldn't loose Sim unlock if it's factory unlocked or if you carrier unlocked it for you after so many months being active with them. You always loose your data when KDZ flashing. You wont get OTA updates if you Crossflash...if you stay with your current rom OTA's should be possible
If you're using a us carrier phone outside of the us, you should just forget about ota. It won't work. Do yourself a favor and learn about the various flash methods. You're gonna need one of them at least to keep it updated.
Thanks guys. It sucks that it's imposible for me to get OTA updates, but at least i can try flashing my phone to keep it updated. I will check the guide and learn more about it then. Anyways i think this is an amazing phone and a bargain for the price nowadays..

As per the title, bought an unlocked G970U instead of U1 by mistake. Should I expect a Verizon splash screen greeting me in the bootloader? I don't wanna see any branding anywhere in my phone. Can I get rid of any of that flashing U1 firmware?

Which G970U phone you have bought. If it was a Verizon branded, then their logo should greet you If you bought T-Mobile variant, then its logo will be present while booting the phone. Flashing is possible and it depends which carrier you have. Also don't you have the phone in hand yet?

Yeah, the phone hasn't arrived yet. In the pictures I can see the box has no carrier logo, but I'm guessing it's Verizon because I haven't seen a Verizon branded box yet. Also, the box definitely says G970U.
I've been a Nexus/Pixel user all my flashing life, so I'm well versed in the fastboot/adb dark arts. How does this compare to Odin? There are so many new terms that I'm still trying to understand: CSC, HOME CSC, USERDATA, etc. Is there any guide I can follow to flash my incoming phone to U1 firmware?

The T-Mobile version is also G970U, so it can be pretty much any carrier. USERDATA file is present in carrier firmware, if you flash unlocked firmware you won't need/have this file.
Link below is for S8, but works for S10 as well. Of course you would need to use firmware files for your phone. I would also use instructions under "Flashing standard firmware" first using Standard Odin. If you get an error when staring to flash, then use (Patched) Prince Comsy's Odin.

Thanks a lot. One last question. I'm based in Mexico (we only get Exynos here), so I got a U version to get the Snapdragon CPU. Obviously I don't want any US carrier branding/blotware in the phone since I couldn't benefit whatsoever from it. What about OTA's, though? Will I get them whenever Samsung releases an update for U1? Or will that depend on my carrier? Should I update monthly using Odin? Do I have to factory reset? So many questions :silly:
The link you provided doesn't work, btw. But I've since found some other Odin guides. Thanks!

I corrected the link in case you need it.
To answer OTA question: I had unlocked U1 model of S8 and when I flashed it with T-Mobile firmware then my phone got OTA from T-Mobile when they release it. I assume if you have carrier branded phone and flash it with U1(XAA) firmware then most likely your phone will get updates when Samsung releases them. You won't have to use Odin every time there is an update if you flash properly. Also, it would be advisable to flash using CSC file instead of HOME CSC, so your phone would be wiped. It is because you change firmware and want your software to be fully compatible. After flashing and you check your phone's software update and see that is shows "not compatible or something similar", then I would just suggest you to do "reset"(factory reset) from setting and after you setup your phone, that message will disappear. Also don't do any software update before flashing as you phone may get a fresher firmware than the one you might be trying to flash.
1) Check your current phone firmware
2) Download firmware you want, but if you can, get the firmware that is a previous one than the current one, so you will check to see how your phone gets OTAs
3) Flash using Odin
4) After that disconnect and let the phone do its thing
5) Set it up and check to see if software update section in settings don't give you any messages such as the one I outlined above, if it does, just factory reset the phone
Hi i am new here and need help with updating my Samsung note 9 i still have a baseband N960USQS1ARI5 but will like to update to the latest firmware. i'm using an unlocked AT&T phone. can anyone guide me? I'm not sure if updating the firmware will lock the phone and the process to update, do I just update the firmware in stages as the updates were released till i get to the latest update or can i update straight up to the latest? I am thinking of using Odin, is that a safe way to do this? any help will be appreciated. Lastly, can I change from the AT&T firmware to lets say a none carrier based firmware so as to stop seeing the AT&T logo on boot up? Maybe switch to a firmware that supports global or international? Does anyone have links to an unlocked firmware update i can use, as well? Please help!
I must state that the phone never updates automatically as it always says the software is up to date.

to your last point, at&t phones are notoriously bad at updating
factory unlocked phones will remain forever unlocked and phones unlocked that are bespoke to a specific carrier will also remain unlocked even with Odin flashes providing that the method employed to unlock it was legitimate. Some unlock methods employ root and only trick the phone into thinking its unlocked. Well, once you remove root, and thusly the trick, the unlock is gone. I have ran across rare examples where the person swore up and down that they unlocked their phone with a legit unlock code and that it relocked to a carrier once the sim was inserted and initial programming completed, but i dunno. Sounds weird to me, but every person who said this also said that the phone locked to a carrier other than the one it came from originally. Take that for what its worth, but i still mostly stand by the first couple lines of this section of my diatribe
If you want the at&t crap gone, get the N960U1 firmware and flash it in Odin. You will need the modified version of Odin to flash it so it can ignore the 255 errors the phone throws up from flashing firmware for a carrier (or, in this case, no carrier) on to a phone that it wasnt originally designated (not designed) for
go to sammobile.com/firmwares, get the info for the firmware you want to d/l, get the Frija tool or Samfirm and download the firmware thru one of those as theyre literally 5x faster and flash it

Hi, my phone is a Note 9 ATT factory unlocked.
Below is the link for my post
I've updated my phone using the link , and still unlocked and working Ok.
I hope it can help you .
https://www.google.com/amp/s/forum....note-9-att-rom-update-sept-2019-t3979303/amp/
[SOLVED] Hey, so I purchased the Note 9 (SM-N960U, baseband : N960USQS1CSF1) about six months back, and for some reason, I haven't received any OTA updates, I'm still stuck on Android 9 :'). I've decided to flash the firmware, but it's gonna be my first time,
And I do have some questions..
1. Is it fine if I flash the latest Android 10 UI2.5?
2. I have the AT&T variant but I live in The UAE, I don't have any European sim either, so is it fine if I flash the Verizon version ( or is there any other recommended Carrier) cuz I can't find any firmware of AT&T.
3. Is it necessary to root the phone in order to get it flashed with Odin?
4. I don't see the OEM UNLOCK option, but that does that matter right? ( I do have the snapdragon version)
6. Are there chances of bootloop or bricking if I follow all the instructions and download the correct firmware?
Lastly, if you guys could offer some tips and suggestions, I'd appreciate
Thank you!
[EDIT] Heres how I did it
1. Installed the latest Samsung drivers for mobile on my pc
2. Factory reset my phone and cleared all the cache
2. Got the U1 firmware for my sm-n960u unlocked phone (as advised by a fellow redittor) from sammobile.
3. Used the patched Odin 3.13.1.3b to do a *clean install* of the new firmware. And done!
Problems I faced: Odin failed to recognize my device, so I had to use another USB port and reboot my pc

Note: I did watch some YT tutorials and have read some stuff, so I do have some basic knowledge on flashing the firmware

1. If there is update available
2. I don't know about U phone
3. No root needed. This is official fimware
4. No need
6. Provided the firmware you're going to flash is correct, shouldn't be a problem. Upgrade shouldn't cause stuck/bootloop, just don't downgrade.
Be sure to find the correct firmware.

Thank you mate! Now I just need some clarification on the carrier issue.
Hi all, I'm new to modding in general so there's many things I don't quite understand, hoping somebody can help.
I bought an S10 from a site which was supposed to just send me a refurbed (italian) S10, instead they sent me the US version, (G973U) and I believe it is carrier locked since it's stuck with Android 9 and doesn't find any update.
I have tried searching to no avail what I should flash to simply unbrand it, and allow it to receive OTA updates without tripping Knox.
The build version is the following: PPR1.180610.011.G973USQU2ASGC and the CRC is XAA/XAA/ATT
Thanks in advance.
You shall call them.
Who and what for? I'm past the point of dealing with those sellers, I just want to flash the phone.
CSC (not CRC).
XAA is a multi-region USA ROM, so I don't think it will change over properly for you in Italy. There are threads here for how you reflash a different ROM. The one I used for my S10+ was this one: https://forum.xda-developers.com/t/...e-links-and-flashing-discussion-here.3905897/ but I am sure there is one like that for your S10 non-plus... find it, follow the instructions, and you should be all set.
Thanks! I'm a newbie, what does it mean it wouldn't change properly? No OTAs? Tripping KNOX?
I have found this which seems to be the equivalent of the link you posted.
So, I should flash the U1 version right? However I see only a file "SAU - 1 - ....", and my build number doesn't end in that, furthermore I don't know which bootloader version I'm at.

Oh ok. I couldn't understand first.
For that, You'll flash in EDL mode. But the problem is if your device is powered by a snapdragon chip, it'll not working seamlessly.

No problem. I'm aware of the mode I have to enter to flash, as above I'm trying to figure out which stock rom I should flash to avoid tripping knox, and to receive OTAs. What won't work seamlessly?
Well, mods can close the thread, found the way to do it. Leaving it in case somebody ever needs it.
First, found & checked the bootloader version (5th number from the right in the build version) since you can only flash older bootloader versions apparently.
Then downloaded through Frija the rom for the unlocked phone variant (SM-G973U1) and the unbranded CSC (XAA)
Then using odin 3.13.3b flashed the rom

Hello, I'm in more or less same situation. When you flashed, which files did you use? All of them or just the AP_*** file?
Never mind. Flashed it anyway, now I don't see the AT&T startup screen anymore which is promising. Firmware version is now Android 11 (SM-G973U1 and not SM-G973U) on XAA CSC. Will see if I get any firmware updates later.
Hello guys.
So I recently got a phone that's stuck with the August 2021 security patch. I wanna flash the latest software so had 2 questions:
1. Should I flash the most recent software update or considering I've never actually updated my phone, should I flash all the previous updates from August first before I flash the latest one.
2. I wanted to know if anyone has experience flashing SM-G998U1 firmware on a SM-G998U phone. I heard you can flash "U1" or carrier unlocked firmware on a "U" or carrier locked phone. Just that you'd lose all your data. I have an SM-G998U locked to Verizon and since I'm not in the US Verizon says they can't unlock it for me. So my only option is to flash new firmware updates. But I can't for the life of me find any Verizon SM-G998U firmware from after August 2021 (that's my latest security patch) online. So wanted to hear from anyone with experience that's flashed "U1" firmware on a "U" phone.

I'm not trying to unlock my phone. It's usable cause it doesn't reject simcards. Just denies me OTA updates. All I want is new software.
Is there another option apart from flashing new firmware if I want to update it? I'd love to unlock the phone but all the websites keep talking about generating codes. My phone doesn't request a code. And I can still use it. If there isn't another option for unlocking, can you assist with the questions I've asked?
Fine to flash new firmware to get the latest.
1. If you flash complete FW using Odin, you can flash the latest, no need to flash intermediate updates.
2. Did you search the forum yourself? See following thread for FW versions of the US-devices: https://forum.xda-developers.com/t/...s-and-flashing-discussion-here.4220111/unread

Thanks so much for all the help Yeah I've seen that thread before. But only firmware available until November 2021. Nothing after. So think I'll try the U1 to U option for now.
