Android N Rom Compatibility? - Nexus 6P Q&A, Help & Troubleshooting

This should be an easy question to answer for those of you that have had this device for any length of time. I am a new nexus user, I just received it yesterday, in fact. Here is my current setup, Android N beta program ota (latest) with unlocked bootloader, twrp, and systemless root. My question is, can I flash any rom of my choosing, marshmallow based or otherwise or do I need to be on stock marshmallow to start flashing the current roms? I ask this because I'm not sure if I'm on the correct bootloader, etc.....
Thank you in advance.

The latest Marshmallow build uses the same bootloader and radio as the Android N Developer Preview, so nothing to worry about there. You would need to flash the correct vendor image for the build that the ROM (you want to flash) is based on. This is standard procedure when flashing a ROM on this device anyway though.

Is there a problem if i update to latest stock rom?

Hi,
i want to buy a new note 4 - the version 910f.
If i update the new phone with stock 4.4.4 rom to the latest 5.1.1 - will there be any problem if i want to install root or anything like this later on? Can i still install custom roms?
I want to now this, becqause if i update my new amazon fire 7 (2015) to latest stock 5.1.1 rom - there is no chance to start recovery anymore for installing custom rom. With only 5.0.1 all is good and i can install custom rom with recovery.
Is there a similar problem with note 4 or can i install latest stock rom and won´t get any problems later?
Only thing i found is that i can´t go back to 4.4.4 when installing 5.1.1? And i can´t go back to 5 when i´m installaing marshmallow because of changing partitions size?
So if i go to stock 5.1.1 it doesn´t matter, because i don´t want to use 4.4.4 and i can still use all stock roms and change to marshmallow later?

No problem if you don't plan to use 4.4.4. Note that if you update to latest 5.1.1
>your bootloader will be locked you can't go back to previous roms or use custom roms which are based on earlier versions such as 4.4.4 custom roms or 5.0.1 custom roms.
>you can still root your phone install custom recovery and install custom roms which have newer bootloaders. However rooting 5.1.1 is bit different because with android 5.1.1 there is an extra security layer in the kernel which detects and stops device from being rooted you need a "permissive kernel" to root 5.1.1. And then you can do whatever you like.
Would it be a better decision to stay on 5.0.1 for the moment and later install 5.1.1 custom rom? To not loose unlocked bootloader?
And one more question: if I deactivate bloatware in application setting off stock rom, is bloatware complete deactivated or is it still running in the background somehow?

You can install 5.1.1 with these bootloaders coj3, coi3, pok1 , coh4 these are safe and won't lock your bootloader. i'd recommend 5.1.1 over 5.0.1 because the difference is day and night in long term use (when u have many apps) 5.1.1 is much smoother and better battery life just don't install coj5 or newer bootloaders. I don't use custom roms because in my experience stock rom is the best custom roms have some bugs etc. If you deactivate bloatware in application settings then its no more running in background.
OK, thank you. But so I should deactivate ota updates and flash latest stock update with Odin, so that I don't get latest locked bootloader?
How can i update to latest 5.1.1 update and keeping the (old) unlocked bootloader?
Do i have to donwload version from smamobile and flash with odin? How can i disallow to update bootloader too?
And if i update with ota - i will get latest (locked) bootlader automatically - no chance anymore to remove it?
-----------------------------
I don´t want to root my phone the first time (because of knox) but later on i maybe want to root too.

There is no way to be sure if the older bootloader will work with latest 5.1.1 rom. So its better to stick with the bootloader which comes with the rom and yes if you update with OTA you will get latest 5.1.1 and bootloader automatically. Just go to sammobile and download 5.1.1 with COJ3, COi3, or POK1 (nordic countries). and Flash with odin.

Updating to Marshmallow on OF1

Been off this thread for awhile (you know how life gets in the way) and was wondering if there are any meaningful upgrades to an S4 with 1545VRUGOF1 rooted via Flashfire. with stock.
C
If you want marshmallow, then custom ROMs are the only way to get it.
Which s4 do you have? Isn't flash fire for the i337?

SCH-1545
Android 5.0.1
I545VRUGOF1
At the time, Flashfire was the only path to root
Look here for a possible answer: http://forum.xda-developers.com/galaxy-s4-verizon
Any guidance? I have the VRUGOF1 Bootloader and consequently was only able to root with Flashfire. Not sure if there has been any development to allow Marshmallow to be put on this device

Yes, there are ROMs for that device. But you can only flash with a custom recovery so you'll have to find one.
Look in the Verizon forum. This forum is for the international version of the s4.

Maybe I'm not being clear, but I was uder the impression if you have the OF1 Build you can only root with Flashfire, and, you cannot install CWM or TWRP as it will brick your device. I am not looking to add another ROM, I am fine with stock. My goal is to see if there is a way to go from Lollipop to Marshmallow safely given my specific device parameters

If you can't install any custom recovery, then there isn't any way you can.
There is no official TouchWiz Marshmallow ROM for the S4, as such, the only way to get marshmallow is through a custom ROM.
A custom ROM can only be flashed via custom recovery.
Ergo, if you can't flash a custom recovery, there is no way to get marshmallow.
The Verizon OF1 bootloader is locked and not exploitable. Only the MDK bootloader had that luxury. You also cannot downgrade to it. If you want to flash a ROM other that stock head to the Verizon Galaxy S4 development forum and read up on SafeStrap and ROMs that can be installed with it. A custom recovery such as TWRP is not able to be installed on your device. Because of that ROMs such as CM, JDC custom ROMs, etc. are out of reach for you.

Thanks
So to summarize, since I am on the OF1 build and could only root via Flashfire, the bootloader remains locked...consequently I still cannot flash TWRP or CWM, and as you put it, out of luck to get Marshmallow.
However, has anyone successfully used Flashfire and Xposed? I saw it on another thread: https://www.reddit.com/r/AndroidQuestions/comments/406o9w/verizon_galaxy_s4_unlocked_bootlaoder/
but there was no definitive conclusion that it was successful. Anyone have any direct experience with this? Since Safestrap and Flashfire are both custom recoveries installed alongside of your locked bootloader, do either work to get to Marshmallow?

You are a little confused. SafeStrap is not a custom recovery so to speak, TWRP is. SafeStrap allows the installation of some mods, etc. on devices with a locked BL. A quick look in the Verizon S4 Android Development forum does not show a MM build that can be installed via SS, only LP builds.
The issue with a locked BL and SS is you cannot install a different kernel which limited what could be installed.
I saw a set of OF1 instructions out on Stang5litre's OP for his ROM. Has this been validated as a stable rom for those of us on OF1?

HTC M8 The Legend and how to Upgrade!

Hello guys i decide to open this new thread to ask a few question to clear this out for myself since it last before long time i almost forgot everything.
I bought my m8 imideately after the release and till now NO other device grab my attention in design hardware Sound and etc. So after years of use i drop it several times u know... and i start to have problems sometimes losing signal sometimes when making a call its a bad ass people dont hear my sometimes i dont hear them or the call just drops etc also several sratches.
Anyway i decide to get A NEW M8 second hand in fully working condition in perfect shape without any sings of use. becuase i really love this device.
The previous one was HTCdevs unlocked then Rooted then S OFF with firewater and right now is still runing the latest S.Team ROM
The "New One" that i bought is with Stock Software, Firmware S-ON all is super stock.
As far as i read i cannot S OFF it anymore like before i did with my previous M8 with firewater.
What i can do in order to be able to flash a custum Firmware?
I don`t know what is best for the phone... because i did update my old device from day 1st till now with every new release of Android or Firmware.
Like i say the new one is super clean Stock
Can i jump directly to the latest Android 6 Custum ROM i want?
what i shold do 1st?
HTCdev then ROT and S-OFF?
if i change the motherboard of with the old one that is fully unlocked this will grand me all benefits of S OFF?
For example i want to go all the way from Pure Stock Android 5 lets says to latest Custum S.Team ROM
what i should do best?!
Thank you in advance
I'll answer some of these questions
1. Firewater no longer works, you have to use sunshine now to s-off.
2. To get the newest firmware just update to newest version through OTA, make sure you got locked bootloader. After that you can do whatever you want - unlock bootloader, flash roms, s-off, etc.
If you have a few bucks to spend, you can S-Off your device, but in my case, I have this phone 3 years already and still S-On and have flashed numerous custom ROM's already and I'm happy with it. ?

As long as the phone is currently on Marshmallow, then yes just unlock bootloader, flash TWRP 3.1, and flash the desired ROM.

Unless you are really skilled with that sort of thing, I'd leave it well enough alone. I've seen a lot go wrong with taking the phone apart. So you risk ruining a brand new phone, for no good reason. Spend the money for sunshine, if you need s-off for a specific reason. But you don't even need s-off for flashing ROMs, firmware, or most other mods.
I'm in the same boat. I just bought an carrier unlocked brand new M8 because.....well....I love this phone. I too have had my current M8 since release but now the charging usb port is acting up. I'm very interested in rooting my new M8. I never did my current one.. My new phone is coming with Android 4.2 I think. Should I I OTA it as soon as it comes in or unlock the bootloader etc flash TWRP before and the just flash a custom ROM?

I was rooted, unlocked bootloader with s-off. I went back to stock and got all OTAs. So, is locked bootloader necessary?

You should OTA and update to Marshmallow before unlocking the bootloader.
Especially if it comes with 4.3 (or anything before Lollipop Android 5), the firmware won't be compatible with the current ROMs, and you will be stuck with issues like no boot, no WiFi, etc. Also, the current TWRP versions will not be compatible with older firmwares.
So short story, you must update in order to flash current ROMs.

Unlocked bootloader is okay for OTA updates. However, you will need to restore a stock never rooted ROM (unrooted will work - OTA will fail) and stock recovery in order to OTA update.
Rooted ROM will cause OTA to fail. Custom recovery will cause the update to get stuck, as it expects and requires stock recovery.
Return to stock ROM and stock recovery with using this guide: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
And to be clear, there are no updates beyond Marshmallow for this device.

I was rooted, with bootloader off, s-off with TWRP. Did not have stock recovery. Found my version of stock RUU here on XDA, thankfully, installed and received all the OTA's. Am now Android 6.0, HTC Sense 6.0 Software Number 6.12.1540.4.

Stock recoveries are posted on the guide I linked. But yes, RUU is a valid method as well to return to stock and/or update. On that note, you could have just RUU'ed up to any version, and not done any OTAs. Marshmallow RUU's for US versions (which yours is) is a slight exception, where you have to flash the 6.12.1540.4 firmware using fastboot, then you can run the 6.12.1540.4 RUU.
No need for s-off to flash a custom ROM/kernel. Just unlock via htcdev, flash twrp recovery via adb, be sure the zip of the new rom is on the internal memory/sdcard, flash it, done. I recommend leedroid + clumsy kernel or ice + clumsy(on ice keep in mind that sometimes it freeze on boot htc logo around the first few restarts, hard restart it and it should be fine, if it's not - clean only cache via twrp and it will boot normal from there on).
I received my new phone, installed the AT&T sim but when I try the OTA system update all it does is say "checking". Can I manually update via PC? What update package should I download from htc?
The phone is currently on Android 4.4.4 htc Sense 6.0 Software # 3.28.401.6

Just Bought a Sprint HTC 10 HELP (ROMS)!

Finally upgraded to a 10 from M8. Glad I did. Right now I have it s-off and bootloader unlocked. Do I have to relock bootloader to flash RUU like the M8? Right now I am running Stock Sprint ROM. My question is how do I remove bloat and gain root? I have always been using SuperSU but now I want to try Magisk. My plan is to flash TWRP first and then Magisk on my Sprint ROM and manually remove bloat myself. I wonder if I flash the WWE_deoxed or Dev version would I mess up my radio and LTE bands/prl update ability? My goal is to have a Stock rooted sense rom with Magisk that works with my carrier Sprint. Also, I want to have the ability to have OTA updates from HTC directly if possible. If I have to flash the WWE or Dev version that's cool but I don't know if I have to change my CID or not. I just want a pure sense rom that works with Sprint and able to take updates? Btw what are the differences between WWE or Dev since my bootloader is already unlocked? will I be able to flash magisk on these two roms? I have read over the forums but there are too much information someone guide me in the right path please. thanks and god bless!

Rooting this device is no different than the M8, for the most part. Before you flash any sort of custom ROM I highly suggest making a backup of your current ROM, to include the system image, as this will help you take OTA updates in the future. Second, if you check OMJ's threads in the Sprint development forum you will find stock rooted ROM's for the 10. I believe he also has Magisk versions that you can install, if you so desire. As far as relocking the bootloader to run a RUU, that's not necessary now. If you plan on using a custom Nougat ROM you will need the latest TWRP recovery, which can be found in Captain Throwback's TWRP thread in the main HTC 10 development forum. I can't really help you with the rest of your questions, as I have a Sprint 10 and run ROM's that work for the device that don't require any sort of modification to the device outside of having an unlocked bootloader with S-off and TWRP.

Thanks for the reply. I am glad I don't have to relock and unlock bootloader again for RUU. Many thanks to Captain Throwback who has been providing stock roms since M8 days. Is there any ways to remove Sprint bloat? I wanted to go to the HTC 10 forum and flash Sprint_WWE rom but i don't know if it will mess up my modem or radio. Any ideas?
I saw that the BadBoyz Modded Rom have Magisk Flash option. What about Stock rooted rom Badboyz posted? I dont see an option to flash Magisk zip onto it. Do I grab a Magisk file from Generic HTC 10 topjohnwu's forum and flash it with Badboyz sprint stock rooted rom? will it be compatible and do I need TWRP to do the steps above? thanks!

Bootloader and modem question

How do I know which bootloader do I have? I'm currently running build B35.
Can someone direct me to a thread how to flash universal bootloader and modem?
If I use bkores flash toolkit, it said you have to flash universal bootloader, modem along with Rom and Gapps but in which order?
If using twrp for future flash do I need to flash universal bootloader and modem every time I switch ROM?
I'm not an expert but here's what I understand.
1. You don't have to worry which version you have unless you're flashing a custom ROM, usually for Nougat you want the B15 and for Oreo you want the B35.
2.Universal Bootloader>Modem>ROM>GApps>Magisk/SuperSU
3.You only need to flash it once if you're switching ROMs with the same android version.

If you haven't you need to unlock your bootloader before you can start flashing custom ROM. You can find a guide on how to do it here.
