Need help / advice in how to flash phone - Samsung Galaxy S7 Questions and Answers

Hi,
I apologize if this is the wrong forum, but I will start here and see where it leads me. Not sure what type of processor the USA phones have.
I am currently using an SM-G930V Galaxy S7 phone originally bought from Verizon, but now used on MetroPCS. (USA)
Since MetroPCS uses T-Mobiles network, I wanted to flash my phone over to t-mobile, so I can get band 12, etc. and get better utilization / reception from the phone.
My concern is that I have never done this process before, and do not want to brick my phone.
I do have my current configuration backed up, using smart switch on my laptop.
Has anybody developed a guide, or instructions?
How difficult, or simply is the process?
How safe / risky is doing it?
Can I actually ruin my phone trying to do this?
Which software version do I use? the U version, or the T version?
Thanks in advance for any help / suggestions you may have to offer

Yes a lot of people have made multiple tutorials for this, and they are all over this forum if you read some threads
If you don't like that answer, imagine how annoying it is for long term members here to have to keep typing out the exact same instructions every day to new members who don't read anything

heres a link for the U firmware QD2 update just download that and odin and use odin to update your phone. Its perfectly safe to use the U firmware on all US variants. Any questions don`t be scared to ask.

Asking questions is fine if they are questions that are not easy to know / find the answers to, or you're having a problem
It's a joke when you come to XDA and make a new thread asking how to flash your phone, that info is literally all over this forum, it just shows laziness

[Q] Samsung Galaxy S Upgrade

Hello all, I have a Galaxy S that is unlocked, i have been trying to install Android 2.2 using the latest Kies software, but all i keep getting is the following.
Current Ver: 2.1 - Update, PDA:JF3 / Phone:JF3 / CSC:JE5 This version of the device cannot be updated.
My wife has the same phone on the Orange Network, this updated straight away with no problems, and works just fine.
I was wondering if it is the fact that if the phone is unlocked, and the update is not possible. We live in the UK. Any help would be greatfully received.
Thank You
I was hoping that this would be the Forum that would have least given a reply to my thread, but it seems not so. I notice that over 200 hundred people have looked at the question.
I live in hope than an answer will be forthcoming, even if somebody tells me to go away.
What kind of Galaxy S do you have?
You can do the registry hack for kies to change your product code and update to the generic rom, however I believe this hack has been patched for the most recent version of kies. I'll see if I can find a link to the hacking guide for you.

[Q] Question about 1.85 one click root instructions

Hi there,
Quick newbie question. the following thread ( whicb I cnnot yet post into) detials a way of 1-click rooting a 1.85 device. However, it mentions AT&T. Can someone please confirm this will work on the international version of the HTC One X as well as I have one on the Orange network in the Uk. I just wanted to make sure these instructions are not US handset specific.
http://forum.xda-developers.com/showthread.php?t=1709424
Secondly, the page suggests I unlock the bootloader aftrewads. Is that 100% required as i have no plans on using custom roms, i just want to be able to use things like Titanium Backup in the full root mode.
R
It will work only on AT&T model as it depends on the AT&T update servers!
Ah, thank you. Good job I didnt give it a try then.
Is there a One-click for the international model? I couldn't see one.

You're in the wrong forum. The versions (Tegra 3 versus Snapdragon S4) have been organized into separate forums to avoid confusion. Lots of things here will brick your phone if install them on the wrong version.

Hi i am new to the droid community got this fone as a gift from a bufdy of mines, got tonrun it on metro pcs network was really to setup. Anyways i update to ota with out doin no reaseach seems like i am stuck with 4.4.4 my question is there a way to root xt10180 non dev or temp root??? Can someone guide me the rite direction thank u
P.s if this is not the rite place pls move post t.y
Considering there is other sections more appropriate than the "Dev" sections for a question or concern, this would certainly not be the right place to ask.
But to answer your question, no. If your BL(bootloader) is locked, you have OEM/Stock recovery, and are on 4.4.4 you are screwed. It appears the Ultra is no longer being supported by anyone capable of finding a method to root. However, you can PAY for a BL unlock code, but it apparently has not been successful for everyone so I personally havent tried and would not pay the premium and possibly get nothing in return. At 4.4.4, you are unable to downgrade to older versions capable of root. Unless someone releases a method of bypassing the stock restrictions - you may have to wait until the next update. Only problem with that is the day after you update, if you choose to, someone may release a tool or method to bypass those security measures. However, if you dont update immediately you may possibly miss the window of opportunity to use a crack-able version of an OTA and wind up being stuck with too new of a version (I am not 100% sure on this last statement, as its been awhile since I was fully involved in the dev world). Hope this answered your question.
Yeah know I am stuck on this version. N I also won't pay for no bl that's not going to work. If someone do come out with a crack version I am willing to donate. I miss been root man. I hope someone do come out with a way to bypass this restrictions. I know they are a lot of smart ppl out there, that can help us noobs lol.

Quick question???

Good morning everyone. I have tried looking through both these forums as well as a google search and can't seem to find an answer.
So my phone is rooted/s off custom Rom etc. My phone originally was a vzw phone used with Verizon as my service provider. I've since switched carriers and am using my phone with cricket being my service provider. Everything works, and works ok. I've been running a venom Rom and truly do love the Rom. But with lollipop being out there, it is time to upgrade. my phone says I'm running 4.4.2. Everything I've read seems that I have to upgrade my firmware as well, which is based off of the build number if I'm correct in what I read. my question I guess is do I continue to use Verizon based roms etc or do I use any variant of it. I guess I'm just seeking some what of a direction to head in. I apologize in advance if it's a stupid question. I've attached a copy of my build number in case that helps. Thank you so much, not only for your time, but any help available. Have a great day everyone

You need to flash Verizon fimware and use Verizon based roms.

This is not the right place to ask for help with this... Check out the "guide" section... And ask questions In " Questions & Answers" section.
I think this is best method:
https://forum.xda-developers.com/v20/how-to/guide-root-twrp-lg-v20-using-dirtysanta-t3722278
Others use h915 kdz.
Please refrain from posting on this thread again. It will make me regret helping.
Don't forget to thank people who help you in the thread with thanks button. Specially if the guide they made helps a ton. Note this will get rid of at&t software. I think there is way too restore it still but I have not checked for a while.
this is helpful

Is there any current way to unlock the bootloader on the LG V20 H910 with AT&T's latest firmware release? AT&T has locked diown the bootloader, and with LG no longer in the cell phone game, they aren't able to provide the OEM bootloader unlock code as well. A few people have also mentioned that the Dirty Santa no longer works on these devices. Any help would be greatly appreciated.

At least did you try to follow the instructions available? According to this post from October-2022 it worked on H910 AT&T.

Yes. I tried it and its useless. Struggling to find a bootloader unlock process that actually works for the H910.

You are looking for help, because you don't know how to solve it. So we as a community need a little bit of cooperation from everyone to be able to understand if it's a limitation/roadblock of the method, or if you are doing something wrong for whatever reason.
So posting: "don't work", "it's useless" and anything like that not only don't help but discouraging others who read this threads. Tell the problem/error that you encounter.
I found another user who said that he flashed dirtysanta directly and once have TWRP he worked around it the downgrade flashing necessary.
As last resort you can swap the motherboard for one that is vulnerable for the exploit.
But if you wanna some one-click "I don't wanna have trouble" solution, I'm sorry that I can't provide that.

I have a clients device that needs to be updated, hence the search to unlock the bootloader and then update the device. The posts I come across, even new ones seem to be reposts of others work from before LG shut down their bootloader unlocking service, so ehen you follow their steps they don't work at various steps. I've been updating devices as far back as Android 1.5 and for some devices its a struggle to update them at all. Replacing the pcb isn't an option right now as the customer won't pay for it. Hence I scour various websites and forums for solutions as other post their success/failure in doing the same on this device. Too often I find people posting about updating their devices, only to find that they either already had their bootloader unlocked before LG shutdown their service to do so, or they just don;t reply to a PM about their process, hence they're fake posts, or old posts from years prior being reposted for no valid purpose. The amount of tim I spend to update peoples devices and test custom ROMs is actually fruitless in terms of money paid, but more for me to keep devices out of the landfills whenever possible. Every time I mod a device I make and keep notes, as well as the files used, stored on one of my NAS as I know I'll be doing it again in the future, including properly and fully testing custom roms to determine if they're actually working properly, or exactly what their issue(s) is(are), and I keep finding a plethora of bugs and issues with too many custom ROMs being pumped out before proper testing. I routinely turn down some device update requests when update steps are convoluted, fractured or even requirements are no longer valid. I'll keep looking around and trying various methods as I come across them. Thx.
No problems, I feel for you because I like to keep people using devices that otherwise would be discarded without real needs.
