Different rom :) For sprint we cannot use the stock rom.

currently attempting to create a custom boot.img that will boot with visuals and fix our battery drain

---------- Post added at 12:48 AM ---------- Previous post was at 12:32 AM ----------

Part 1 of the above complete. I have visuals on a modified boot.img. Part 2 has to wait because I screwed up and accidentally deleted my rom :/ so i am about to go through setup wizard
[LG V20 Guides, News, & Discussion] Nevea:
Awesome stuff!!!!!

Been following this thread for weeks and weeks now.. Got my V20 and was so upset about the bootloader... You guys are doing amazing! Can not wait until the tweaks are all worked out and a stable ATT version is available :)
[LG V20 Guides, News, & Discussion] me2151:
Minor ATT update(at least a H915 update) we are able to replace the BL using the same method. Also had the same exact service problems as the sprint model. Our guy has gone to bed but he is trying to get alot done.

---------- Post added at 01:35 AM ---------- Previous post was at 01:25 AM ----------

And a much needed update. No more battery drain i hope. Nothing is constantly resetting and crashing like before and the phone is running cooler now.

Always had faith in you guys. Let me know where to send money for my ls997
[LG V20 Guides, News, & Discussion] d0p35m0k3r:
Many thanks for everyone's hard work. It's much appreciated. I am eagerly awaiting to void my warranty and remove some Verizon bloat! :D
[LG V20 Guides, News, & Discussion] Slypnslyde:
Yes I also would like to mention thank you too all who participated in this.
[LG V20 Guides, News, & Discussion] me2151:
When we release there will be a list of all involved. Please thank them all then :) especially [MENTION=3802703]glitschi667[/MENTION] as he was a big part of it.
[LG V20 Guides, News, & Discussion] ubergeek77:
I want to mention that I've had issues with this on other phones in the past. For some reason, a lot of the advanced calling features are baked into the ROM. Even if it's available across carriers, and even if you see a setting for it, it won't work right if you aren't using the correct ROM.

For example, when I still had my LG V10, I had the T-Mobile variant, but I was using it with an AT&T SIM card. Things such as VoLTE, Video Calling, and WiFi calling did not work properly.

I'm sure this is something that's already being looked into, but I wanted to have it written down here, too.

Admittedly, I'm a little apprehensive to flash the unlocked ROM to my V20. I'll do it if there's absolutely no other way to root, but I'm still very apprehensive about it. In my experience, there's always something that doesn't work as intended, and the complications build up the longer you use the phone.

I'd be in paradise if I could keep my AT&T ROM + root <3

Just my 2 cents. I'll donate the remaining $39.98 when the time comes :p
[LG V20 Guides, News, & Discussion] me2151:

[LG V20 Guides, News, & Discussion] elliwigy:
[MENTION=4609377]me21[/MENTION]52 has Sprint.. itll prolly be the most refined out of all the variants lol
[LG V20 Guides, News, & Discussion] Logantbrown:
Woooo, can't wait for the method
[LG V20 Guides, News, & Discussion] jellybear456:
Getting more hyped for this as the days go by. Seriously amazing work being done here. And those other "well known" developers for LG wouldn't even take this on.

You guys rock:svetius:
[LG V20 Guides, News, & Discussion] twistedvip:
Curious, I see you've worked a little bit on the AT&T H915, but has there been any tests on the H910?

Twisted
[LG V20 Guides, News, & Discussion] me2151:
Pm me.
[LG V20 Guides, News, & Discussion] ubergeek77:
Wait, AT&T has two different model numbers for this phone? I had no idea.

......why though?
[LG V20 Guides, News, & Discussion] twistedvip:
I thought that was strange as well, but yes apparently it does. Mine is the Titan color LG-H910. If yours is Silver, that may be why, but if not I've got no clue why there is a need for 2 different variants...

Twisted
[LG V20 Guides, News, & Discussion] ubergeek77:
I guess that's what's going on then. I have the Titan Gray, and it's an H910. I just don't see a reason for them to do it like that :silly:
[LG V20 Guides, News, & Discussion] AllGamer:
H915 is from Canada, H918 is from T-mo
[LG V20 Guides, News, & Discussion] Gman_aka_Pop's:
I have been following this thread since the start. I have also offered to be a tester for the AT&T Model just so that's out there amd I am very knowledgeable in this field. However it was stated that the Titan Grey is the LG-H910 and that the silver a different model number correct. Well my phone is also a LG-H910 but it is the Silver version. Keep up the good work devs and I'm looking forward to being able to gain root access on my phone. It is the only thing I am missing with this phone. :good:
[LG V20 Guides, News, & Discussion] me2151:
I see that. I do remember that. I will probably need 1 more AT&T tester so it will be you. Just not ready for that yet. Im don't a revert to stock test right now on my sprint
[LG V20 Guides, News, & Discussion] Gman_aka_Pop's:
Sounds good Im here when you need me just PM me. Thank you for all the hard work it is very much appreciated.:good::good:
[LG V20 Guides, News, & Discussion] jellybear456:
I have an AT&T silver V20 and am in the US with the model H910. I don't believe there are two different numbers.
[LG V20 Guides, News, & Discussion] twistedvip:
I just remember there was someone on here who had the H915 and was on AT&T. Not entirely sure why there would be two different models - but at least the vast majority seem to be H910.
[LG V20 Guides, News, & Discussion] AllGamer:
it's not uncommon for people to buy SIM unlocked version of Canadian models to use in USA.

in the past I helped a lot of fellow XDA members purchase Canadian version of few model of phones not available in the USA, to have it SIM unlocked and used over there in USA

either due cleaner ROM /firmware or because bandwidth are more widely compatible, etc.

for example this time around the LG V20 it'll be one of few phones featuring LTE66 which is not yet available else where, and we will be getting that firmware upgrade soon.

which also means, your regular H910, H918 are supposedly be able to also unlock the same LTE66 frequencies with the proper hack, or ROM upgrade.

Willing to test on sprint not trying to derail u guys awesome thread
[LG V20 Guides, News, & Discussion] me2151:
Don't need anymore testers. AT&T works basically out of box. I am pretty much satisfied So i will be starting the steps to release :D
[LG V20 Guides, News, & Discussion] eldedo:
Woot! Let the tweaks begin, no more ads and bloatware
[LG V20 Guides, News, & Discussion] ubergeek77:
"Basically out of box" as in we get to keep the same ROM? :laugh:

Or that the debug ROM doesn't have all the weird issues that were cropping up earlier?

h y p e
[LG V20 Guides, News, & Discussion] me2151:
AT&T works on stock rom. Will still need a data wipe to root just like T-Mobiles. but works on stock rom.
[LG V20 Guides, News, & Discussion] ubergeek77:
This makes me so happy, you don't even know.

Thank you, and everyone else who's been an integral part of this project, very much. I've never seen development move this fast before. You guys are the best.
[LG V20 Guides, News, & Discussion] pbedard:
Is it hard to do it sorry for beeing a bug
[LG V20 Guides, News, & Discussion] the1stSecond:
[emoji115] [emoji122]

This is great. Thanks very much to everyone involved. It has been a long time since I have been able to root. I came over from a Note 7 (and have had almost nothing but Samsung devices for years, all on AT&T). I am glad I will have control over my device once again.
[LG V20 Guides, News, & Discussion] me2151:
I am trying to simplify it as much as possible. At this point. im not even doing the installs on tester phones anymore. im just giving the testers some instructions and its going through.
[LG V20 Guides, News, & Discussion] Ryuk359:
You realize you guys have made history right?
[LG V20 Guides, News, & Discussion] Krillen:
I am not sure is has been said or not (I must have missed it if it has been) but does it work with stock rom on the Sprint variant of the phone witch I have.
[LG V20 Guides, News, & Discussion] ubergeek77:
World record for "Fastest bootloader unlock + root?"

T-Mobile doesn't count for this, of course. That's cheating. :cool:
[LG V20 Guides, News, & Discussion] Ryuk359:
Even just cracking a lg bootloader is praiseworthy certainly. Rarely rarely done. Nice work gents.

Tmo never counts when they give you the keys to the castle. The slimy magenta castle. :cyclops:
[LG V20 Guides, News, & Discussion] CromDubh:
Canadian H915

So I have a Wind Mobile /Freedom Mobile H915, will we be able to use the same procedure as the AT&T?

Thank you so much for all your work. When I found out that the Wind Mobile wasn't the same as the TMobile version I almost returned it. So glad I held off now.
[LG V20 Guides, News, & Discussion] me2151:
Sprint is the only one of the US carriers that needs a custom rom unfortunatly. I have put together a rom for us on Sprint so we will not be missing anything :)
[LG V20 Guides, News, & Discussion] ubergeek77:
I just thought of something: once this is all said and done, we should definitely pin down a list of general precautions to KEEP root.

Mainly OTA updates. Potentially, there could be an OTA update that unroots the phone and relocks the bootloader. We would need a way to stay safe from OTA updates in the event they somehow auto-install (I don't even know if that's a thing, but just in case), or know which OTA updates are safe to install without losing root.

And using LG UP to restore is probably completely out of the question now.
[LG V20 Guides, News, & Discussion] me2151:
The method does work on the h915 but i am unsure of the status on his service. One of the devs owns this device.
[LG V20 Guides, News, & Discussion] jellybear456:
In the past, like on my old G2 D800, titanium backup freezing software updates and OTA updates usually keeps them at bay. This shouldn't be too big of an issue unless something changed, which it certainly could have.
[LG V20 Guides, News, & Discussion] Krillen:
Yeah I will be missing what I want witch is my phone fully stock with the ability to use root apps like titanium backup. That way I can get debloat the phone and restore apps with data from my old note 4. It's a shame I need a custom room witch I never use unless the phone is not officially supported but still supported by the community. I was really looking for root with stock room too. Guess I can no longer have root, what a shame. The most I would be willing to put on my phone to have root is a deodexed stock rom. Nothing different to that of stock other then it's deodexed and I have root. If there is no way around needing a custom rom then I am forced to live with out root from now on. I will hate it but will just live with it wanting apps I never wanted or use off my phone ect.
[LG V20 Guides, News, & Discussion] me2151:
The way TWRP is now is that OTAs cannot be installed when the system is set to write access(only way to get root) Until they actually try there is no way to know for a fact though.
[LG V20 Guides, News, & Discussion] ubergeek77:
Oh, that's right. I had this issue on Android Wear all the time. It tries to reboot into stock recovery and auto flash, but it can't, because it boots to TWRP instead.

Can't believe I forgot that.
[LG V20 Guides, News, & Discussion] Logantbrown:
Thanks dude! Will you or someone be making a post with some instructions and what-not when the time comes? Excited!

Edit: for sprint specifically I mean
[LG V20 Guides, News, & Discussion] me2151:
I will be a little more specific. This custom rom is a US996 STOCK ROM that has been deODEXd and I have added some files to allow proper sprint connection. Its still the same LG rom but no bloat(no sprint apps) and proper apn files and other stuff. Its not like a stock aosp rom where its pure google. looks and feels exactly the same as a stock rom. just added steps when doing everything.

---------- Post added at 03:47 AM ---------- Previous post was at 03:41 AM ----------

Its not much else. Just install the rom. But I will be adding it to the guide. I have a sprint device my self.
[LG V20 Guides, News, & Discussion] Krillen:
Well there is one stock Sprint app I need. It is the Voicemail app because i don't know of any other way to know when and if I have voicemail other then see I missed a call and call my voicemail everytime witch is both annoy and waists call time unless i do it during my free time. Anyway is there anyway to go back to full stock with out root should I not like the rom. I don't want to possibly root and use the rom to find out it is not the same, not liking it and want to undo it. I just want root with my stock rom. I like being able to choose witch apps I remove myself and witch to keep. I don't like custom roms unless my phone is no longer supported accept by the community.
[LG V20 Guides, News, & Discussion] me2151:
Might be able to add the app separately. I am currently working on a way to return to full stock.
[LG V20 Guides, News, & Discussion] rickberg:
You Sir are amazing! The whole sprint community is raving because they finally have root and you are whining because you have to use a modified stock Rom? If you had any positive brain cells you would know the sprint visual voicemail is a apk that with a little help from Google is all over xda in sprint deodexed roms.

Rather than complain about something that has been released for a few hours after many people yourself included begged for root. Why don't you thank the people who spent countless hours and countless nights to make this a possibility one of which was said to be virtually impossible.

Why don't you ask if you can help deodex the Rom etc instead of asking for more. And if you aren't capable of making the stuff you think you have to have work. And don't want to have root or even bother to at least try to help then SIANORA AMIGO!
[LG V20 Guides, News, & Discussion] Krillen:
Thank you for that and all the hard work you are doing to give us root on the sprint. Also would it be to much to ask to have all the stock lg apps for the v20 be made available to everyone so they can choose witch apps to install if any. I ask because I have read that there are some lg apps that some of the variants of the phone like the Sprint variant just didn't receive on their phones at all.
[LG V20 Guides, News, & Discussion] me2151:
At the very least. I cannot return to stock on my sprint model due to the setup wizard continuously crashing. So If you are a Sprint user. This is a one way ticket. It runs great for me though. and honestly. Its your choice if you want to take the risk to root. Krillen I suggest you stay unrooted
[LG V20 Guides, News, & Discussion] elliwigy:
all of the lg apps are in the US996 deodexed rom... it doesnt have the Sprint garbage or other carrier garbage...

if you want the apks once its available you can download the rom and extract what you want if you dont want to install it and root your device
[LG V20 Guides, News, & Discussion] Revan365:
Hmm. Think it'd be worth in on my lg v20? Sprint here. Mainly just wanting that root level control for tethering and any other customization I'd like to do.
[LG V20 Guides, News, & Discussion] elliwigy:
only u can answer that question, i dont know you lol.. its a no brainer for me though
[LG V20 Guides, News, & Discussion] me2151:
I already have hotspot hack enabled for native hotspot in the sprint rom.
[LG V20 Guides, News, & Discussion] A_Richie:
That's all I needed to hear. SOLD
[LG V20 Guides, News, & Discussion] Krillen:
What if the person didn't know how to do that? That is why I ask for them to be made available if possible. I am happy we have root but not happy we don't have stop rom with root. Not just like stock custom rom with room. I appreciate all the work done to give up room but it's not the room I truly want. I may use the custom rom root but only if I am about to undo it should I not like it. I have always never likes custom roms unless the community were the only ones to support it still or the stock rom was just that bad. I am not knocking the work being done just giving my opinion.
[LG V20 Guides, News, & Discussion] EMSpilot:
Probably best if you don't root.

Cheers
[LG V20 Guides, News, & Discussion] Krillen:
I am not doing that at all. I love the work that has been done to get root. I just like my root with the stock unmoded rom. I only use a custom rom if the official support is done and only then has community support. I never did say i would not use it accept if there was no way to undo it should i not like the rom. Having room makes me very happy, having it via a moded rom is take a moded rom like it or not or no root for you. Sorry if that makes me seem ungrateful or putting down the work the guy has made but it's not. I just see it as I am being forced to have something I don't want or care for just to have something I do want witch in this case is root on my phone but with my stock Sprint rom. I have always had my phone till they went out of official support. That is just my opinion that nobody has to like or even agree with. Sorry if my opinion is causing any problems, that was not what I meant by my opinion that i'm entitled to have.
[LG V20 Guides, News, & Discussion] me2151:
I advise you to not root using this method then. Wait until another root method is available (if one does become available) and be happy with your stock rom. I may make minor updates to the Rom I have done but it will not be a constant update thing. There is NO reverting to stock after this. So i advise you not to do this since it isn't what you want.
[LG V20 Guides, News, & Discussion] Krillen:
I agree it's the best for those who like custom roms but not the best for those who prefer stock with root. Also so you all know I do want to try root out when possible but I hope I will be able to undo it should I not like it or need to undo it for some reason. I wouldn't want to be stuck with it should I not like it. I like my phone fine enough with out root minus having apps I don't want or need being unable to be uninstalled. I would love to be able to free up the space for other apps more useful to me.

---------- Post added at 12:24 AM ---------- Previous post was at 12:19 AM ----------

That's a shame no way to undo it is being made available. There should be one so if the anyone should need to undo it for any reason at all they could. Every time i have rooted a phone like my old Note 2& Note 4 both on Sprint I have always been able to undo it should I need to.
[LG V20 Guides, News, & Discussion] me2151:
You have been warned. If you don't like it and want to revert I cannot help you. Maybe once LG gives us the TOTs we need it will be possible
[LG V20 Guides, News, & Discussion] Slypnslyde:
I use YouMail it's way better than stock
[LG V20 Guides, News, & Discussion] Krillen:
So you can't help with undoing it should anyone need to or will not (not to sound rude like it might)? What good is any root if the way to undo it is not given along with it? I would love to use your root while having the way to undo it should I need to do so.
[LG V20 Guides, News, & Discussion] me2151:
I CANNOT HELP ON SPRINT DEVICES. It is impossible to do. That is the END of the discussion. I will help ones that are possible but it IS NOT POSSIBLE. Since you cannot undo my root, do not use my use.
[LG V20 Guides, News, & Discussion] jspsuperman:
Take the hint guy, if he could undo it he would. [MENTION=4591212]me2151[/MENTION] dont let ignorant people bother you, you are doing amazing ?
[LG V20 Guides, News, & Discussion] A_Richie:
It's like talking to a brick wall, isn't it? Lmfao. Some people
[LG V20 Guides, News, & Discussion] AlkaliV2:
Alright, so it's been awhile since I was on Sprint but I went ahead and looked into the file(s) you are talking about and I'm thinking it is the Sprint Visual Voicemail App. The plus side is that with TWRP, all things are possible. You need to verify what version of VVM you are running right now (open the app and check) on Nougat because that is the one you are going to need when/if you install the custom ROM (US996). The VVM apk goes in:

/sys/priv-app/VVM

with one other file called "libsmsimediaset140603.so" in /sys/priv-app/VVM/lib/arm , but the numbers at the ends are likely a release date for that file. Anyway, you either create a flashable zip to extract to those directories or you can push the files there manually and change the permissions to make sure Android recognizes them on boot-up (rw-r-r).

Once that is done VVM should be up and running on your phone since me2151 has already included the connectivity files for Sprint.

Now I'm going to have to assume a few steps of the exploit to get you best case scenario, but keep in mind I am not a tester and I don't know that this is what we do to unlock the bootloader.

I assume:

1.) There's a root shell to get fastboot control and pass the command to overwrite the locked bootloader with the debug bootloader and reboot to the unlocked fastboot menu

2.) Once in the unlocked bootloader menu fastboot flash TWRP and then boot to your recovery (TWRP)

If those two steps are accurate then the next step is to perform a backup before applying root. When you first boot into TWRP backup your entire stock system to your External SD card. Leave it uncompressed so you can go through the files yourself on your PC later and find the VVM folder I'm talking about. This will enable you to add the folder back in after you've rooted because now you know where it goes. You'll reboot and launch VVM and if it worked properly you should have voicemail notifications on a majorly de-bloated system.

Scenarios listed from worst to best:

Worst Possible

: TWRP doesn't do backups. At all. Then you won't be backing up the ROM system you'll be scouring the net for the APK with the same version number.

Still Pretty Bad

: TWRP does backups, but not to the external SD card or MTP doesn't work

Things are looking up

: If you can backup the system ROM to internal memory and MTP copy it to your PC without failure

Best case

: It backs up the files and saves it to the external SD where you can safely remove it and manipulate the files to get VVM back.

There's some advanced stuff I mentioned above but nothing you can't technically do yourself. If you don't understand what I'm telling you in the method above I'm going to have to agree with everyone else that you shouldn't root until the TOT files are available for complete restoration of the device.
[LG V20 Guides, News, & Discussion] Krillen:
Would you please explain to me why you say it is impossible?
