How can you flash back to stock? - LG Stylo 2 Questions & Answers

I picked up the Boost variant Stylo 2 at Best Buy since it was only $50. I have no intention of activating it on boost, its just a nicer, cheaper iPod (hard to beleive people actually still buy iPods). Im hoping to unlock if possibe in the future though.
I took out the Boost Sim and popped in a Sprint sim on first boot, then tried a TPO sim just for giggles (said invalid sim with TPO). Anyhow Ive noticed that there no Boost or Sprint bloatware whatsoever on the device and im wondering if ive crippled the network capabilities by putting different sims in, as ive read Boost now does that (not even sure where i read it). I figured Id try and see if I re-flashed it with a stock ROM if id see some Boost/Sprint software, only Im finding it impossible to do so. I managed to find a ls775 kdz (zv3) here along with the lgup ls755 dll's but the phone isnt recognized properly. Theres literally no support from LG for this phone. I havent taken any updates and running zv5.
EDIT: I watched an unboxing and didnt see any boost/sprint software on the device either. Nevertheless, would still like to know if I can flash back to stock if I screw it up messing with it.

Kdz zv3
Did u ever get the zv3 kdz to find your phone i did hit me up

Questions on rooting and SIM unlocking (S4 eumk2 4.3)

Hey guys,
I'm new to this forum. A while back I found a phone in the gas station bathroom that I was working at. I kept it under the desk with a note and of course the camera watching it in case it disappeared without a customer picking it up. No one ever came for it and after 2 weeks (company policy) I took it home with me. Anyway, I've just been using it on my wireless internet and playing games, however my phone contract just ran out on my crappy verizon old flip phone and I want to go to straight talk and use this one.
So, I bought the Straight talk byop kit which includes a sim card for the phone, however, the SIM card that's meant for AT&T phones is too small for this one for some reason, however the TMobile one fits in it perfectly fine. The problem is that it's a tmobile sim card and I'm sure you all know that I need to unlock the phone to get it. So, last night I spent about 4 hours searching for ways to unlock it. I see it's possible to do it for free using the system settings phone codes, but the code combinations don't seem to work for me.
*#0011# - When i key enter 1 it doesn't do what the video I was watching says it's supposed to do.
*#9090# - Restarts my phone after I hit the what I'm told to.
There's another I tried however, I can't remember the code, it takes me to the debug menu, however option 6 isn't there to give me access to phone options or whatever.
So, I gave up as my laptop battery started to waiver around 10% and went to sleep.
Now, today, I hopped on and attempted to figure it out again, but got bored really quick, stumbling accross the same stuff I tried last night, so I tried rooting it thinking that getting admin access to my phone would make option 6 appear when I entered that number. I was wrong, but hey, I successfully rooted my phone so it's cool.
Anyway, I just want the SIM card to work. I really don't care if I have to unlock my phone or whatever, I just want my phone to be able to make calls. So if unlocking my phone works, please help me, if there's a way to get the super small AT&T SIM card to work, then that's be great.
I'm sure you need some of my phone info to help me out so here we go.
It's a Samsung S4 on 4.3 firmware, rooted. It's an I337 and the baseband version says I337UCUEMK2.
If you need any other information to help me out, please feel free to ask. I tried calling AT&T already btw, they said without a phone number they won't provide me with an unlock code.

I honestly don't understand 90% of the words in that post... Is there a post or article that'll teach me the basics to rooting and unlocking? I'd really love to do custom roms and everything. I honestly thought when I rooted my phone it'd give me admin access and the hidden system management options would become open to me.
Anyway, hope you can help, my wife is getting on my case about getting it unlocked. If I don't have it done tonight, she's going to make me add the straight talk to a different phone instead of this one and I really don't want to use a cheap piece of junk straight talk phone.

I'm doing research on getting a custom rom installed right now, I'm looking at Carbon ROM. I guess I have another question, is there any roms that give me full access to system manager or whatever it's called when you enter those numbers?
Okay, I made an attempt to use your walkthrough, method 2. I went and downloaded odin, and tried to flash the mdl modem however they don't exactly explain in the walkthrough how to do that, I figured I'd take a hit at it and went to do it and odin says it failed.
Is there a walk through I can read through to find how to flash?
I'm not sure what safestrap is, I can't find it on my phone and google only brings up droid ones for me as far as I've seen. It sounds like if I get the mdl modem on my phone that because it unlocks the hidden options in system manager I just have to do that and use the system manager walkthroughs I've seen to go ahead and unlock it.
EDIT: Okay, I got safestrap installed, now I'm just trying to figure out how to get a different modem installed, any help there? I'm looking and asking around but I'm not seeing anything.

[Q] note 3 won't detect SIM card, also won't shut down

I got this from a customer he bought a new phone and told me if i could fix this then i could keep it... Decided to start here... Everything seems to be pointing to a bad update... Tried to do self recovery but i feel it needs to be totaly reflashed... I had anothet note 3 and switched the bords to make sure that it wasnt an anntenna problem or anything else besides the motherbord or software... Is there a way to fully flash this again? Like the basband and Android? I know u all flash ROMs but id like to get stock working first... Tried Kies but wont reflash it... Maybe a way to get it into emergency recovery mode so it will reflash it?
I havent done any flashing since my SII i know Odin was relivent, where would i get 100 stock verizon 4.2? And its like the old ways right?
I figured out how to reflash it.. But im leaving it's off just in case someone else came across the same problem it's almost like there's no SIM card inserted even if you pull the SIM card out sometimes it does sometimes it does it never shows the network and it never shows a signal strength over .99 also its not showing IMEI number was just super weird, it keeps pointing to bad software... If reflashing it dont fiz it ill post some screenshots...
My first note 3 killed 3 sim cards before verizon finally replaced the phone under warranty. The phone may still be under manufactures warranty if the phone is under 1 year old. I cant wait for my upgrade so i can get a non samsung device. I love the size and most of the hardware but first and foremost it is supposed to work as a phone which is does not. Plus bloatwiz is a freaking joke even in rooted custom form.

[No service] rooted v20 h910 connection issues

I bought an unlocked h910 on ebay a little while ago and rooted it the day I got it by following the typical root guide. Everything seemed to go smoothly with rooting, and I have SuperSU and the stock rom. I have had terrible connection problems ever since rooting. I never actually used the phone with a sim before rooting it (my other device takes micro sim and I didn't have an adapter, do I got a nano and activated over the phone after rooting). As soon as I put the activated nano sim in, the phone would lock onto a tower and continuously drop and say "No service", then lock again, repeat repeat.
After a little while, the phone magically fixed itself and was working OK for the rest of the day. Then the next day, I started getting the No service problem again. I tried lineageOS with the werewolf kernel, but that didn't quite work out due to crashes. So, I figured I would do the typical restore procedure from this thread:
https://forum.xda-developers.com/v20/how-to/stock-att-h910-stock-recovery-boot-image-t3528060
That went through OK, and I figured everything was fixed, but then I started getting the No service problem again after a little while :crying::crying::crying:. At that point, I decided to do some reading and it appears that some folks with unrooted phones have had connection issues on the v20 that they got warranty replacements for. I am concerned that there may be a hardware problem that is causing the No service issue if other people have experienced this too. Unfortunately, since I never used the phone with a sim before rooting it, I don't know if it was working correctly before rooting or not. I can say that it was sold as "new, sealed box", however, with original packaging.
Now I am at a bit of an impasse. The service on the phone works sometimes, but is not reliable enough to be usable, so I went back to my other device and have had the v20 sitting around doing nothing for a bit now. I am tempted to send it back to LG for repair, but it has clearly been rooted already and since there are no kdz files available for the h910, there is no way to revert to complete stock. So I suppose I am hoping someone can give me some ideas here. I have been trying to figure this out for weeks now and haven't had much luck. As I see it, here are the options:
1. Perhaps this is a software problem that someone on the forums knows how to fix, which would be ideal. I have seen some threads regarding modem settings, but none of the ones I have seen apply to the h910.
2. If this is a HW problem, I could send the phone back to LG as rooted and effectively guarantee I will have to pay the repair cost. I have no idea how much that will be, but I would like to avoid it.
3. I could intentionally brick the phone and send it back claiming that it bricked itself. Seems ridiculous, but I have heard of this before.
4. Sell the phone as rooted. Haven't had much luck in that regard yet.
I must say that having a very unreliable phone has not been a pleasant experience so far. Can anyone offer some advice?
Does anyone know if LG is going to make a fuss about the phone being rooted if I send it back to repair? Can they at least reflash it to stock kdz for free?

Help with a very odd issue

Hey there, first time poster , long time user of this site. I started using this site about four years ago when I needed help modifying a HTC one V, and from there on out I haven't been able to stop modding and rooting. This site has been so helpful, you have no idea
To date I haven't had many issues with the unlocking of boot loaders and rooting, installing roms and also network unlocking.....Until today.
I am currently trying to network unlock a Samsung s5 neo. I did indeed buy the unlock code from Koodo (the original service provider). However (heres where its going to get weird), no matter how many times I try putting the darn code in, it plain well just refuses to take it. I can sit here all day and nadda a thing will happen.. IN FACT I thought after 10 times it would hard lock its self, resulting in me having to buy a unfreeze code. But nupe.
I'v used 3 different sim cards to try to get this phone unlocked but nothing, Bell Mobility from my LG G5 phone, A PC mobile sim and a Eastlink sim (By the way I'm from Canada)
I tried flashing (odin) with koodo OEM roms, from the first one which i think was 5.1 up to 6.** not sure where it left off. Even went as far as flashing with Telus rom, as koodo is the sister of Telus, and still it sits there pretty much laughing at me.
Factory reset from both with in the OS and the recovery menu, used every code for the phone dialer and half refuse to work. Installed shortcut master (Yes I'm rooted) and keeps saying locked. Also been trying to sim unlock both unrooted and rooted.
I'm completely mind blowen, i even said what the heck and bought a code off line for kicks and sure enough as soon as it showed up in my inbox, same EXACT code Koodo gave me. So we know the code is right.
Any help would be great as I'm at a complete lost. this is the first phone iv had , i'v ever had this much troubles unlocking. OH and if it helps "KNOX" is disabled
P.S I have no idea if i posted this in the right forum , sorry if i didn't.
Thanks

Help/advice with Unlocked Sprint LG LS997 V20

I recently switched carriers to Tmobile and couldn't be happier, they also paid the remaining balance on both my v20's
I requested for the phones to be unlocked which they did.
it of course isn't a phone I want to use as my Daily since I got the V30+ but just for the hell of having a backup
I tried my tmo sim card and it worked I just had to set apns.
Last night I decided to reset the phone cause I hate that sprint bootscreen and also wanted it to be fresh.
I tried putting the Tmo sim card again and now it won't even recognize the sim is in..
So anyone with more experience would or could point me to make it work again ??
I would really appreciate any feedback
thanks!!
No one??
Did you just do a standard factory reset?

Yes!
Settings/backupand restore/factory reset..
And I also cleared the attached Data profile from Sprint with a ##code
Does the t mobile SIM card you're trying to use work in any other device? Ensure that SIM isn't just worn out from you taking it out and inserting it into phones by trying it in another phone. Also confirm the phone sees the Sprint SIM when that one is in. Pay attention to how both SIMs sit in the phone to see if you can see one of them sitting slightly further into the phone or something like that. I'm not sure how you expected your boot to not have a Sprint logo on startup if you did a factory reset though because as far as I know that's just part of the stock OS bootup, even if the phone is running a different carrier.

THIS is the stupid world of Sprint. This is what exactly happened to two LG XPowers I had with Sprint. My GSM SIMs worked great with the XPowers until I reset the device to factory settings or that the device went through a security update. You unfortunately have to get Sprint involved with the unlocking process from their end. And getting Sprint to do something? Good luck with that.
Had I not been getting unlimited free service from Sprint I would have left it some time ago and it's not for their phone or data service, but unlocking devices that is a pain in the ass!

Yes The boot logo goes away when you reset the phone..
When it activates then u get the sprint logo.
The sim card I used work just fine on another phone, I actually thought the same thing you mentioned but nothing.
And yes indeed the sprint sim card reads just fine just no service.
Thanks for your willingness and suggestions though
