Questions before I buy an M9... - One (M9) Q&A, Help & Troubleshooting

I have some probably stupid questions that hours of searching hasn't yielded a firm answer to.
I'm looking to buy a used M9 with the intent of running Lineage 14.1 on it.
Questions:
1. Not a question, but the only international M9 I've found has a bad microphone, so I probably won't go that route. Otherwise, I'd go that route.
2. I'm thinking that an At&t one is my best bet as I'm on cricket and probably will be for quite some time (at least). I've read that (unlike my POS At&t S4) the bootloaders are unlockable but the real issue is gaining s-off ( which is needed to install and not just boot TWRP, right?). Can S-off be attained on a phone that has the OTA Marshamallow update installed (as I have yet to see one on ebay that is for sure 5.0)? If not, is there a way to revert one back to 5.0 so I can?
3. Failing that, there is T-mobile. First, do the T-mobile ones have a different GSM/LTE modem, or is it the same as the At&t version? Second, my understanding is that even if an app-unlockable T-mobile phone unlocked it is one accidental partition write away from loosing the unlock. Is that true, or are app-unlocked T-mobile's permanently unlocked once "permanently unlocked"?
4. On the Lineage OS site I only see a listing for US GSM M9's. Is this a combined image between Att and Tmobile, or is only one supported (or lumped into the international GSM version)?
Sorry for the dumb questions, but having had to return two LG G4's over similarly stupid Gotcha's, I'd like to buy without having a 75% chance of having to send the bleeping thing back because I can't actually install a rom on it.

Will, I won't answer all the questions, but still, u do not need S-OFF to install TWRP or roms.
U only need to unlock your bootloader.
And be sure to make a system image backup if u ever been to go back to stock, or take an OTA.
The "readme" thread is your friend. ?

I feel stupid. Somehow I missed that thread... That answers my questions, Att phone it is.

Which part of the software depends on rooting?

So I just got my HTC One M8 last week (my carrier is Verizon). After seeing how terrible HTC Sense is, I decided I want to root and then flash CM. I rooted my last phone, the Samsung Galaxy S3, but this seems a little bit harder. I've looked at a few guides, but I'm afraid that there is a certain piece of software that depends if the root will work or not. On my S3 I just had to see what Android version I was using, but this phone has a few different types of software. Which one do I pay attention to? Android version, HTC sense version, software number, PRI, PRL, ERI... Also, when I rooted my S3 and then wanted to flash a rom onto it, I had to reset the flash counter because I was on Verizon. Does it work that way with this phone too?

There is only one way to root verizon htc m8 because verizon doesn't allow htc boot loader unlocking. You have to visit the firewater site and gain temp root, then soff, etc.. You should check the verizon forums. I will go ahead and tell you that ALL aosp roms including cm are very buggy right now and not daily drivers. Sound buggy, wifi messed up, calls make beeping etc.. Maybe try a better sense rom that supports verizon. Here are the verizon forums

[Q] 16GB Optus (Aus) Version of G3

Has anyone here used it?
I was wondering what firmware etc it was on as i get one this Saturday. I'm also assuming we arent lucky like the t-mobile version and have an unlocked bootlater as default? I Have always been addicted to flashing roms haha, been doing it since the HTC Dream (I.e the G1) days with jesusfreke root.
Having come from a Nexus 4 where it is easy to return to root/relock the bootlader if you need to send in for a warranty, What is it like for the G3? If i put TWRP on there and something hardware wise goes wrong, is it easy to relock etc? I have read about the LGFlashtool but notice a lack of availability of the Optus Firmware to use as a backup
Cheers

[Q] Note 3 User - Moving to LG G3 - Please Help?

Dear LG Friends,
Long time XDA member, coming from the Windows Phone days HTC, then to Android HTC, bunch of Samsungs, and am now thinking about the LG space. More specifically moving from the Note 3 (T-Mobile US) running on the AT&T US, to the LG G3.
Before I do, I need some help from you guys. Which variant should I go for? I know my primary choices will be the T-Mobile and the AT&T variants (I believe they are 851 and 850)? Based on what's important to me, below, can you guys advise which variant to get?:
1. Development Support - Which variant has the MOST amount of Custom ROM options, that is on-going and kept current? I am spoiled with the Note 3, which has a massive development support. I have never tried the LG OS/Skin (escaping me what it's called), but if it's anything like the TouchWiz on Samsungs, I think it will be important to have CM/AOSP/AOKP and etc support.
2. This is related to # 1 - But I heard that only T-Mobile has the unlocked Bootloader? However, doing some research, I believe the AT&T and the Verizon and Sprint variants can also be unlocked? Is this true? If so, are they anymore limited than the factory unlocked T-Mobile variant?
3. LTE bands - I will most likely be using the phone on AT&T US, but if development options/support are higher on other variants, I might consider buying those models, even if they are missing some AT&T bands. For the Note 3 - T-Mobile is a Pentaband phone, meaning it had all the bands needed, so it could easily work on AT&T LTE, all the time. The reverse was not true.
And basically that is it. Initial instinct says to go chase the T-Mobile variant, based on my needs above. But please educate me and help me out if I have missed something. Thank you so much in advance!
Any input guys?

If you want OTA updates i suggest sticking with the AT&T variant since you have a valid AT&T sim. If you use a AT&T sim in a T-Mobile variant you wont ever get OTA updates and that means missing out on necessary fixes
1. All 3 US Variants are mostly the same, all have CM12 and all the random obscure AOSP roms as well
2. Well unlocked bootloader isnt that fancy it just means theres fastboot mode compared with the other editions where fastboot mode doesnt work properly even if you enable it. It essentially just makes installing TWRP easier since you dont have to root before installing it unlike other variants
Nevertheless Lollipop can be rooted on all US Variants right now really easily. But the only downside to it is that removing custom roms sometimes can be a pain since you have to use a way where it sometimes works and sometimes doesnt

Hi Friend,
Thanks for your response, this is very helpful!
No OTA is never a thing I consider. Everything that matters to me, is what I listed already.
So, is the development support (new ROMs, updates and etc) the same for all US variants or would you say one variant is particularly more popular?
As for the locked bootloader, I thought you needed an Unlocked bootloader to flash Custom ROMs, no? It seems like "Bump" fixes this for Verizon, Sprint, and AT&T and gets you TWRP on your phone, but do we need to do extra steps everything to the boot.img for non T-Mobile variants? Or is it a one time mod and then regular flashing and Backups with TWRP?
If it's the same for all variants after Bump, then you're right, I will likely stay with an AT&T variant, thanks to that Band 7 LTE.
Thank you again for your help, hopefully more can chime in !

No need for any steps. Its just install TWRP and your on your way to installing whatever rom you want
Unlocked bootloader means that the system doesnt security (consistency) checks on system partitions
For LG G3, its because someone cracked the encryption for the kitkat android bootloader which means people can sign non stock boot.img without having to worry about unlocking the bootloader.

Gotcha, thanks again mate! Another (hopefully last) question. If I buy G3, where someone had already OTA'd to 5.0+, will I still be able to root it, install TWRP and get KK ROMs, like CM11 or something?
And vice versa, if the phone comes with KK, do I need to patch with Bump and then I can install ROMs?
Thank you again!

You can root it but i dont know if installing TWRP will work. I didnt want to try it incase it doesnt work and it runs the factory reset script instead. That happened to me once before
But i would say just to be sure, downgrade back to KitKat to do it
Yeah, if the phone comes with KitKat just root, install TWRP using root permissions and then your on your way

This is helpful, once again bud. So how would I downgrade back to KK? Would I have to run a stock firmware of some sort? In Samsung, he Flash a .Tar file through their flashing tool called the Odin. Would that be similarly done here?

[Q] Updating an unlocked LG G4. No rooting.

I have the LG G4 H812 (Canadian model). Bought from Bell and unlocked to use with Koodo (they don't have the G4) I read somewhere you can update an unlocked phone (because you update over WIFI) then I read that you CAN'T. That you have to root it and build an OS/ROM. I am not prepared to do that because I'm pretty certain I would ruin the phone. I'm terrified to even try. Rooting might be ok but building a OS/ROM? Forget it! I mean WHY do I want to build an OS? I just want to be able to update my phone! Not go through a bunch of crap. But no somebody said you HAVE TO build it...
So can I get android updates on my phone or not? It's running 5.1.
Watching this video. Would this happen with an android phone? youtubeDOTcom/watch?v=o8gGb2lqJjE
And PLEASE no "GO away newb. This is for developers only la la la". I'm asking here because I can't get a straight forward answer anywhere. I spent almost $800 on this phone and I want to be able to update it without it getting ruined in the process. Or else I will have to return it. I don't want to because there are no other phones I even remotely like.
Not sure what you mean with update. If you mean updates from LG, sure no problem. My unlocked G4 (H815, asian model) on AT&T was updated this morning, using wifi. Root not necessary.

I would assume that since you are just unlocked in the carrier sense and not Root/Bootloader unlocked that this should not be an issue.....I mean I have never heard of this causing a problem before now.
I will try to look around and find out a concrete answer for you though as like you said, would hate to have something negative happen to that wonderful (and expensive) device.
Updates won't be a problem. I bought a G3 from Rogers because Telus didn't carry the LG Line. I immediately sim unlocked it so I could run it on the Telus network. Received the lollipop update with no issues.

Install stock SM-N910W8 on SM-910V

Hi, just bought an unlocked Note 4 from USA, it's the Verizon version.
I looked on your forum to find an answer, but I can't.
I'm from Canada, and I'd like to install a stock rom of the canadian version (n910w8), to have less Verizon/Amazon bloatware, and the french language available.
Considering that the N910W8 phone is pretty identical(from what I can see..), same CPU, would I brick my phone from installing this very rom "N910W8VLU1BOE2_N910W8OYA1BOE2_N910W8VLU1BOE2_HOME.tar.md5"?
And if so, why? And what are my alternatives?
see rooting and now you can unlock bootloader too first head to this post
then after that whatever your stock rom you can uninstall the blotware
here are another post for the blot which is safe to remove
and you can use that thing
I am using Indian sim and it is working great
'and you can use that thing'
That thing? The .md5 i mentionned?
When you boot the phone it says 'custom' and has a lock/unlock symbol?
You purchased it unlocked?

I purchased it unlocked, but it has a Verizon logo whenever I boot it. So, would I be able to install the n910w8 without any trouble? Or is there a way to "install it" and during the process if it is not compatible it will tell it to me?

He's trying to make sure that "unlocked" means that your bootloader is unlocked. It's a critical point, especially if your "unlocked" is referring to being open to all carriers.
If your bootloader is unlocked, you'll see an open padlock on the first boot screen. If the bootloader isn't unlocked, you won't be able to flash any ROMs until you unlock it.

Now, after a few more research I understand what you guys were trying to make me understand haha
I'm unlocking my bootloader, but my main topic question remain unanswered.
Will my phone be able to take the n910w8 rom even if I have a n910v? (once my bootloader will be unlocked and everything..)

The ROM, maybe. Will it work? Not without some serious help.
Since the Verizon variant of this phone isn't getting much developer love... it was locked until recently and true Developer Editions were rare and in smartphone terms, it's old... people are looking at the Snapdragon development.
The biggest headache will be getting the phone and data to work. The W8 is a GSM phone while Verizon uses CDMA.

Ok, I guess I could say I'm a superhero, my name, SuperStupid -_-
I finally got the padlock logo, rooted my phone, installed TWRP, tried to flash n910w8 rom, it didnt work, so I told myself, why not wipe everything, so I did.
Now I have a phone without OS, but! I kept the padlock and TWRP...
A new successful achievment for SuperStupid...
I'm currently downloading (with my superFast 1mb/s connection) the full firmware of N910V, which I didnt think prior to wipe everything, to keep a copy...
And I hope that I'll only have to put the file on my SD card, and then flash it...
I'll stay with my Verizon bloatware, as soon as I get it back, I won't try again soon to do this ****!!!

You'll have to root again, ya know...
I have a Verizon Note 4 arriving today for use in Canada. The seller indicated that it is unlocked which I'm sure refers to the carrier and not the bootloader.
I've owned the Notes 1,2 and 3 and my most stable and satisfying experience was with the 3, not because it was the latest and greatest but because it was the only one I did not root and play around with. I'm getting older and I'm starting to value stability over features. I actually like stock touchwizz and enjoy the built in productivity of the spen. Carrier bloatware really is a minor inconvenience for me.
I've enjoyed the Note line but the Note 4 will be my last as the SD card and removable battery are very important to me. As long as this Verizon Note 4 gives me LTE coverage in the Greater Toronto area (which my research indicates it will) I'll keep it stock. A bonus would be if it shows up with Android 5.1.1 or is upgradeable via OTA or Kies. I don't really see any North American varient receiving Marshmallow and certainly not this Verizon one.
Can you flash N910W8 firmware/rom onto a N910V?

Same here with a N910V wanting to know if N910W8 can flash ok to it. (but already unlocked mine with custom N910V roms on it) Been running LineageOS roms OK for a while but just too many bugs for something dependable.
Runs nice until you really need it not freezing on you lol.
Did try a custom W8 rom that was only flashable after installing TWRPCAN 3.0.2 in place of TWRP 3.2.3 and it did startup but phone ran really hot and broken WiFi so ended up going back.
