ls997 to us996? - LG V20 Questions & Answers

is there anyway to fully convert it? I got a sprint version for a really good deal and im on att. Or atleast flash the modem or does it do that when you flash that rom?

I can unlock the device for you, I have another free slot available.
Message me on skype: stoney.lawson
https://www.youtube.com/watch?v=fFl8_FDffp0 for video proof

Okay, I did. but would it matter if im on the us996 rom?

If you're on that rom the device is unlocked

Well then the real question is can i flash the modem that goes with the rom? or would it brick it for my purposes?

Flash the entire rom from the dirtysanta thread..
have you done so already?

I did. I know it unlocks it but what im asking is does it flash the modem with it? searched all over couldn't find if it did or not.

I'm not too sure, it's all in the carrier settings in the software, you're fine and good to go, don't stress it any further

No there's no way to do so and stay away from this idea or else you'll end up with a similar story.

Well really im just looking for the modem. Looks like he flashed the entire KDZ. Does anyone know if just the modem flashing would work?

Actually he performed US996 KDZ flash got no signal - than flashed directly DD part of LS997 modem.
The problem is that EMMC partitions are different and with different start/end address locations so you are hard-bricking your device this way when you overlap them and the only way to restore it is low-level via JTAG.

Well this kinda sucks lol stuck with using us996 roms because somehow it unlocks the device.

I really can not understand why are you thinking that you are stuck on using US996 ROM only...
If it is about SIM lock - you can easily unlock your device...

yeah but if theres already a way to unlock it (meeting requirements) without paying then why would you pay for it...

[Q] Installing another S4 carrier's modem

I have an I337 running on tmobile network. I have tried both tmobile's and at&ts roms and both get 4g but the att&t rom seem to connect faster. I am currently on mdl modem and woul like to experiment with tmobile's modems and am wondering if it is safe?
Thanks in advance

I heard doing this could possibly erase your IMEI number. Personally, I'd only flash my carrier's modems. Just to be on the safe side.
Its not wise to use other carriers modems, and it will clear the IMEI, but I have heard that it can be done. Kinda of a hit and miss thing, if you are going to pursue it, backup your efs first.

Your welcome, and trust me, do not get into the IMEI restore thing, you talking about a pain, try that once.
good choice. in all the diff radios i have flashed on various phones they gave no more than minimal improvement if any
i thought initially the mf3 radio was better, now not sure

I hope I'll never have to go through that but if I did, can you share the steps? With my s3 (may it rest in peace) a simple "reboot nvbackup" and "reboot nvrestore"command in terminal emulator was all it took, and it saved me many times. Would this also work with the s4?

You're right that has been my experiences with different radios also.
replacing the IMEI, talk about a hardline approach from Samsung.
I remember on my S1 flashing radios from S1's all over the world, Europe, China etc etc
Though thanks for this thread, I was actually wondering about flashing a canadian modem, to unlock AWS and since it's one build higher than the AT&T modem
Just a reminder, it is not wise to run other carriers modems, the modems we have are sufficient to do what you need, and if you find a way, you will not see much of a change if any.
Good luck to all.

Hey man, i am starting to think i would have to flash another variants modem on my s4 m919v because i dont see any modem files for my phone on xda or atleast i cant find many because this variant isnt all that common. What do you think its possible right?
Oh and the reason i want to flash modem is because i want to flash an older modem for s4s that allowed them to be unlocked using the *#0011# code and i cant do that currently. I have heard flashing an older one will allow me to unlock my phone.

These are my only unlocking options?

OK, I just come across an S4 SGH-i337M running 5.0.1 locked to Bell. Searching Google is fairly mind boggling as everyone has their own method. In my situation, I'm pretty sure I have come to this solid conclusion. Two options only,,
1. Buy unlock code or
2. Downgrade to at least 4.4.2 and use the hidden codes method.
Can #2 be done safely? Some sites say if you do try downgrade from Lollipop to KK, it will brick. What would a safe procedure be if possible.
Thanks

Thanks, seen this but wasn't sure. I assume that flashing back to Lollipop isn't necessary if one chooses to stay at 4.4.2 for a while. Heard some comments about increased battery drainage etc. on Lollipop.
Will try this once the new charge port shows up and I can replace.
The hidden codes method won't work, unfortunately. Let me know if you are successful.
Thanks.

Thanks, will do. Hopefully will be getting to it tonight. Here's one of the confusing things I was talking about. Been doing alot of reading, and in your instructions, you install TWRP to flash SuperSU and such. Then, reading elsewhere, I see this "SAFESTRAP IS THE ONLY RECOVERY WE CAN USE!
Don't even try flashing another one.", posted in a thread about AT&T SGH-I337 model. Well, here it is, halfway down in the second post, bolded in red. http://forum.xda-developers.com/showthread.php?t=2616221 Just trying to get things figured out, it's been a couple years since I last played with the Galaxy, just getting back into it now.
The AT&T version of the s4 is the Sgh-i337 and, if it was running stock 5.01, the bootloader would be locked and twrp cannot be used.
The Canadian version of the s4 has the letter "m" at the end of the model number and the bootloader is not locked which allows the installation of twrp and custom ROMs that are not based on a tw kernel.

Thanks, this method seemed to work,,just one problem I overlooked, but I just assumed this phone would work on AWS1700,,wrong lol. I was reading the 141 page thread and there seems to be a few different methods for doing this. With my S3, I only had to flash the NV and run a script on every boot as the nv rewrite would not stick. Is this so as well with the s4 too,,or is there a method to make it a permanent stay. I didn't plan on updating to 5.0.1 quite yet,,but will do if needed. Do you no of a recommended/preferred method for this?
Did you test the phone with another sim card? Hopefully, you will not be prompted to enter a network unlock code.
For AWS, I'm not sure what needs to be done as I am using a Telus s4 on Bell.

It was locked with Bell, my provider is Eastlink,,I finally got the AWS1700 band working, but kept losing it when the phone went to sleep. Updated to the NE1 modem, then had to flash the AWS again and all seems to be working fine. Hopefully it holds up. Thanks for everything.
Glad it is all working. We're all here to help and learn from each other.

Difficulties after switching to T-Mobile

Hey guys! Thanks in advance for any help or clarity you can provide.
I had to switch to T-Mobile from Verizon. My device isn't rooted, modified, or in any way different than factory. However because of the switch I've had some functionality that I've lost. Namely the ability to get software updates. This phone has been rooted before, and I'm very comfortable with the process of loading up different software. The question I can't find anything on is whether or not installing the T-Mobile firmware will brick/cripple the device. I know there are different chipsets so I'm trying to figure out the best way to keep my phone up to date without being on Verizon anymore.

You can flash T-Mobile's firmware or the U firmware without any problems. There are tutorials here in the forums that will walk you through the process.

I tried finding something about loading the T-Mobile firmware on a Verizon device but I haven't had any luck. Only guides on doing a regular firmware update on a T-Mobile device. Should I be worried about the Exynos/Snapdragon differences? I hate asking for something so simple, but could you please point me in the right direction? I'd LIKE to try and go that route, because the U firmware had poor battery life, a lot of heat generation, and requires a patch just to get wifi to work. Then again maybe I'm thinking of the eng boot we had for rooti. I do love my all day battery quite a bit.
Thanks in advance.

T-Mobile, Verizon, and the U phones all have snapdragon processors. No need to worry about that.
Read through this thread here as it pertains somewhat to what you're trying to accomplish. Read it from start to finish so you don't miss anything important.

@Outbreak444 Thanks for the help. Last night I threw G935U-PI3 on the phone and literally everything worked out of the box. Even wifi calling and (seemingly) VoLTE. It's taken care of all my issues. I can't get over the fact that it's now an out of the box solution and it works flawlessly.

Hey, a friend of mine just got the Verizon s7 edge and is trying to get it to work on T-Mobile. Did you have to get the phone unlocked somehow, or did you just install the U firmware and everything was fine. My friend's data is not working. Thanks!

Just look on the forums on flashing either the U firmware or T-Mobile firmware using Odin. It's a fairly easy process if you read through the steps thoroughly. And you don't need to worry about unlocking anything.

I'm familiar with flashing the U firmware, as I did this on my Sprint s7, but my understanding was that just flashing the U firmware didn't open up the bands. But are you saying that flashing the U firmware alone was enough to get TMobile fully working?

My understanding it does. The hardware between the phone's should be the same so it's software that's affecting it. But the U firmware won't allow wifi calling and other carrier specific things unless you're rooted. So pick and choose.

FRP Locked LGV20 H918

Reading up on some things, Maybe I could flash it back to stock using LGUP (Not sure if i can do that without usb debugging and dev settings) and hopefully use dirtycow? I have no idea
Phone: LGV20 H918
Android ver: 7
Security Patch, May 2017
If you have any questions feel free to let me know, thanks!

Depends on the model. I've heard H910 doesn't have a kdz. If you can find a kdz for the phone, you can use LGUP or something else I've heard called UPPERCUT, which is the same as LGUP but better in some ways... I haven't done any flashing, especially since just unlocking the bootloader on my model is nearly rocket science.

H918 does have some KDZ's but I can't seem to find one for H91810D
This is the closest i've found so far. https://build.nethunter.com/misc/h918/v10d/
I have 0 clue how to flash that at ALL.
There's plenty of guides to flash kdz files. Wish I could help, but like I said, I haven't done it myself. Search around, see if UPPERCUT is better.

Safe to flash H91010I to US99610N with LGUP?

Hi all,
Have an AT&T branded V20 in Australia so not getting updates. Also can't use the hotspot without it being registered on AT&T network.
Want to know if its safe to flash a KDZ, thinking US99610N as its from the unlocked variant?
Have a few questions:
Is it possible?
Anybody know of a good guide to do it?
Risk of hard/soft bricking?
Possibility for recovering after possible brick?
Any help is greatly appreciated, been trying to find answers on my own for ages to no avail.
Thanks!
Root your phone, then flash the latest H910 firmware. There are two zips that are in the ROMs forum -- one will take you back completely to stock, and the other will upgrade you, but leave TWRP, you can decide which one.
As for flashing the US996 firmware, it may work, probably won't brick your phone, but there is no reason to...

Would updating to a newer H910 firmware still leave me with the issue of the hotspot wanting an AT&T connection? That's the only reason I thought to flash to US996 as its unlocked so would think that's the only way to alleviate the mobile hotspot issue.
Thanks again for your reply!
Search for 'H910 root' in News and DIscussions. I made a thread specifically for the H910 up to V10r.
Have you ever installed the mobile hotspot app for the carrier that you use on any other phone? If so, go into the playstore and search for it -- you will be able to install it.
For example, I use T-Mobile with my H910, and after I debloated all the AT&T crapware, I just went into the playstore and installed all the T-Mobile apps that I need. If for some reason that isn't possible for you, you can always side load them. The bottom line is, that while it may work, you will probably have more trouble if you flash another models firmware. There are exceptions, but why do it if you don't have to

Thanks heaps for your replies. I'm not trying to be difficult (but probably kinda am), I guess also my reason for looking at the US996 route is I live in Australia and that model was sold here, the H910 wasn't. So if I flashed to that wouldn't I be getting OTA updates, not having to flash every time?
Also with the hotspot, this is just a little bit of a foreign concept to me. I've owned plenty of Android phones but this is my first non-Nexus. All the others I've bought from overseas and its been as simple as settings>network>hotspot & tethering and away you go. So with this one I have to download an app? Seems stupid for something that is such a basic feature and is built into Android. I'm not sure why they bother with all this crap, stock Android is better in every way IMO.
Again really appreciate your guidance.
Well, all I can say is try it. It isn't going to brick your phone so bad that you can't recover, but the recovery process would involve you flashing the H915 KDZ and rooting. In order to do that, you must be at ARB 0, so make sure that whatever US996 KDZ that you flash doesn't increment ARB. Also, let's say that you flash the US996 10c KDZ and it works fine, but down the road you take an OTA that increments ARB AND doesn't work. You would then have no way to fix your phone.
Just trying to point out some of the pitfalls you may run into.

No I appreciate the pitfalls being pointed out. I thought it was the safer way to go but guess not... I'll take a look at your thread you mentioned earlier when I have a bit of time to actually do it. Or I'll just wait until a big update comes out, 8.0 or something. Thanks for all your help.
