Hi everyone I'm new to samsung devices but definitely not to android in general since I come from years of htc devices, root, flashing and so on.. still I am facing a bit of confusion here so instead of writing in every single thread I'll ask you here my questions:
1. As I read on TWRP official thread "it's incredibly hard to brick a sam device"; anyway I understand that this is never a risk free process but reading the comments it seems like people on nougat firmware are facing some kind of trouble so my question is: Is it safe to flash twrp on nougat firmware? And which one? 3.1.1-0 latest version should be fine right?
2. Let's suppose I'm now on twrp but instead of rooting the stock rom I flash directly a custom rom, I still need to flash "dm-verity and force encryption disabler"? After some reading I see people that flashes this after every new rom, someone suggests to use 2.2 version but the latest is 5.xx and the content of the zips is different between this two versions (5.xx contains a chromeos folder, the other one no??)
3. "Update modem and bl" , this is meant for those who want to flash a rom based on a higher firmware right? I'm on the latest (may security update) so there's no need to update modem and bl at least I think (?)
That's all, I'm sorry for this long post and my bad english!

Hello all, and please help me with some small details before rooting.
I have an LG G2 with stock KITKAT 4.4.2., baseband M8974A-1.0.190084,kernel 3.4.0., build D80220b, software D80220b-219-02.
My questions
- do I need to upgrade stock firmware to D802d or D802f before rooting, and if yes wich is more stable
- is a SIM card needed (as inserted in the phone) for rooting process
- do I need to unlock the phone before rooting since it is locked with my local carrier (TELE 2 HR)
- does a custom ROM automaticly eliminate OTA upgrade and so prevent from bricking, or it must be unchecked manualy
- when installing a custom ROM (probably Cludy G3) do I need to flash a new custom kernel or it doesent mater (probably Bruce if it is compatibile)
- how does one check for compatibility ROM - kernel, is it just simple as finding "stock ROM" - "stock kernel" in the title
- do I need to instal a new KK baseband before custom ROM since I am allready on KITKAT
- do I need to do any kind of factory reset and/or wipe before rooting or later instaling a custom ROM
Thank you very much in advance, I have been searching all over for this simple answers but couldnt find any,
Sorry if the questions are too noobish but I am afraid tostart anything before I find the answers

1. You don't have to upgrade because you can use rooter that is compatible with your current firmware build, the differences between the firmware are only on their features, with less case of minor problem solved from previous build.
2. No, you don't need to put your SIM on.
3. Custom ROMs are meant to give you better performance of the current build, especially if it is Stock Based Custom ROM. Why you shouldn't update via OTA? because with several changes in the custom ROM, Official build will find it different from its official release, which would cause errors that could ended up with bootloop, even worse.. Hopefully, several developers also have their own OTA feature so people can easily get the update.
4. It doesn't matter since Custom ROMs sometimes come with their own suggested kernel that fit with the ROM. But you can also try other kernels if it suits you.
5. Yes, it is quite that simple, but also try to find out whether it is compatible or not with the ROM.
6. No, if you already on KitKat, you don't need to flash KK baseband.
7. Only when you are about to flashing new ROM..

Thank you very much for your detailed answers !! :good::good:
Can someone please explain to me the importance of updating firmware?
What exactly is firmware that only Motorola can touch?
Why can't this be included while installing a ROM?
Does Motorola somehow have the capability to touch a certain partition that we cannot?
If you flash official Motorola stock ROM, how does it differ from flashing custom ROM?They cannot do the same thing?
Lastly, if the Samsung galaxy S3 is already running 7.1, then why must we update "firmware"?
I know for a certainty Samsung stopped pushing updates long ago for the S3. Please help I'm very confused by this! I've never known to do this in all my years of flashing yet you all keep mentioning it here! Only thing I've known to flash outside of ROM was the radio/modem/baseband whatever you wanna call it. And that was a flashable zip.
How can old phones get new custom ROMs if there are no official releases for current "firmware"? Thanks all! Links and input appreciated!

Updating the firmware is necessary because the firmware brings a newer version of bootloader and for it to be compatible you need the latest version of bootloader (B1.03 right now)
Other phones need firmware or driver updates too. Sometimes they can be baked into the rom or an additional zip. It's up to the manufacturer how they deploy drivers.
Also the well known sim on/off switch is a driver inside the modem. And if the manufacturer don't release the source you cannot see the changes and need the stock rom/files to flash them prior the custom rom to get newer drivers.

Don't discuss here, ask your question in the thread you're following the instructions to upgrade to nougat please. BTW Your given information is not specified enough to help you out.
Thanks everyone for your assistance! I appreciate the information.

I notice there's a huge ...problem in custom rom makers and their ability to speak proper English. Not to offend them, but it's just really a problem. Decent instructions are skipped, and words are omitted...not sure if they're foreign or what's up with that.
The confusion is currently I'm on Android Stock 5.0.1 Rooted.
Only one thread for Aurora ROMS mention flashing "BL/CP". If I flash a new BL - firstly - would this NOT lock the bootloader/remove the ROOT off the device again?
In which case - wouldn't this remove Custom Recovery etc?
So confused. A lot of 6.0.1 based ROM makers are not even mentioning custom bootloader and modem.....which leaves me wondering if I need it
Forgot to mention I have bootloader currently unlocked

I think it's less about the language barrier and more of an assumption that you already know what you need to know. It's sometimes hard to remember that a lot of people aren't on this site as much as the people who post ROMs are on it. So a lot of the basics get missed.
To answer your question though, you do need to be on the proper bootloader that corresponds to the rom that you want to be on (6.0.1 roms=6.0.1 bootloader) and depending on which model of the note 4 you have it will relock it. For instance, I have the SM-N910V and in order to get from the 5.0.1 bootloader to the 6.0.1 bootloader there's a bit of process involved (it's not as easy as just flashing a bootloader in Odin and being ready to go). I would look in the specific forum for your particular model to see how others are upgrading their bootloader and go from there. Most of the instructions that are posted with the roms in the main snapdragon section are for the F model and sometimes the G so the instructions for upgrading don't really apply anyway if you aren't using that model.
Hey I want to install Lineage OS on my S5 G900F. I had this rom not long ago but I remember I had random reboots. I don't really understand how the bootloader and modem works ( I've read other threads before opening this but I'm not sure what to do so it's best to ask instead of breaking the phone ;D). If I will have android 7.x which bootloader and modem should I install? The latest and if yes where can I get download for those (I saw there is an option to extract it from official rom but the official one is version 6.0.1 so I'm not sure what to do).
If anyone can clear my misunderstanding and help me I will be glad, Thanks!

I am not using it but on the official LineageOS thread they recommend bootloader+modem combo from the latest available stock firmware which is android MM 6.0.1 of course.
You can get them for example from here (newest ones are: BL - CQI6, Modem - CQA9).
Thanks for the replay in the end I went back to stock rom and reinstalled lineage OS. Phone runs smooth and no crash until now. I think my problem is solved.
Sorry for this noob question. But i appreciate any answers...
Most of the rom devs advice to flash 'latest firmware' before flashing their roms. First of all What is meant by firmware? Is it the original rom when the device is bought? If yes then why advise flashing latest firmware and then clean flash custom roms?. I mean the latest firmware gets wiped on clean install. Then why recommend latest firmware flashing?

OEMs usually refer 'ROM' as 'Farmware'.
But when developers say 'Firmware', they usually mean 'Baseband' or 'Radio'. This is not a full Stock ROM, but only a small part of it. It stays on the device even after Clean Flashing.
When an update of Stock ROM released, it mostly comes with a newer & updated Firmware (also called Baseband or Radio). Developers sync those new changes into their custom ROMs and Kernels when they release a new build, for a better experience (they usually mention it in the changelog, like - 337 sync).
Sometimes few features of those new custom ROM or Kernel builds may not work properly if a device is running on older version of Firmware. That's why they advise users to flash latest Firmware.
Updating Firmware is easy. Just flash the latest version's zip file via Recovery. That's it. No need to wipe anything. And this procedure won't wipe any user data either.
I hope I cleared your doubts...

So you are saying it is always good to flash latest firmware. Right?. But in which partition does it sit?

Sometimes Baseband can reeduce internet speed.
It is probably stored in Modem partition.
