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..

I'm going looking into flashing a custom ROM on my sister's i337m (on Rogers) . Currently it is on Lollipop OTA update, and she says that ever since the update it has been super slow and laggy. I told her i can flash a custom ROM and it should be much better performance (in my experience good custom roms can provide much better performance than stock firmware in most cases).
I'm not familiar with the S4 specifically but have been using custom ROMs myself on various other phones so i generally familiar with the procedures involved. Just want to ask for advice on a couple points.
1) From what i've read so far i am trying to decide between Goldeneye and Kangapop. both seem to be pretty solid options. I noticed in the install instructions for both it mention that the i337m useres need to have 4.4.2 baseband and bootloader. Is there any specific one that works better than others i see a few different stock versions of 4.4.2 for i337m Rogers on sammobile (MG1, NC1, NE1, NI2) I am currently downloading the most recent NI2. Just not sure if specific versions have any bugs, flaws or advantages/disadvantages to worry about..
2) I figured while i'm going to have to downgrade the firmware to install the custom ROM i might as well try the Root/Unlock procedure from this thread . Is this still working? I think i would need to flash the stock NI2 firmware then follow the procedure in that thread to root and unlock the phone then from there i could install Goldeneye or Kangapop? Has anyone done this or can confirm if it should work this way.
Thanks
Hay there! I just installed Costom Rom on my Galaxy S5 G900I after a great stuggle at one stage i thought I bricked my phone, but lucky this time. All thing is fine even great with custom rom the issue it that, It change my device information and it is Note 5 Now here is my questions?
1) How to know my Build No ( orginal one before custom rom)
2) If I want to installed another Rom then how to find my phone match's Rom?
Thanks and Sorry, If i wasn't clear enough.

Hi Jabbarshah
If you followed xda tutorials by the letter, you have made a complete Nandroid backup before starting any modifications.
Just in case the information you eagerly need isn't present, you may restore that backup and regain access to it.
What lasted after ROM installation can be easily visualized using Phone INFO ★Samsung★. Specially Hardware and Personal tabs are stock information.

Your main information while seeking for a new ROM is the model SM-G900I. Nothing else matters.
You will just need to take care, for future flashes, that your bootloader and modem are matching (closer enough) the firmware you are flashing.
Example:
a) If you intend to flash PopWiz Telstra v5.1 that is compatible with your G900I, would be kinda complex as @iris28 doesn't clearly states which firmware version he's using. The information may be somewhere onto his thread but unfortunately isn't advertised as should.
b) THE GALAXY PROJECT by Master @djb77 states clearly that he's using Lollipop XXS1BPD3. :victory: ... so you end opting for it.
Now you just have to search for the closer firmware you can find that will match (not exactly) TGP. You have a complete list at Sammobile SM-G900I. Seek for your country/provider with higher Lollipop (5.0) release. If you are unable to find a flashable Odin file for that, you may do it yourself (xda way)
Hope I could be clear enough.
Have fun.

Hi guys,
I see several Roms in the Rom Section that require to flash a new Bootloader and Modem.
I can't find any explanation why this is needed or what it changes.
Afterr flashing those. Is it than necesarry to reflash stock if you want to try another Rom.
Would be glad if someone could please elaborate on this topic a little bit.
Thanks

But before flashing anything make sure your device version is supported by the rom. I am in canada and have a w8 version device, not all roms support this device.
You need a new bootloader and modem, if you are upgrading to marshmallow or adding a custom rom. As the older roms do not support 6.0.1 and custom roms have a base from a different device (usual F series of the international devices). You would then reflash the bootloader and modem for your particular version if recommend by the rom developer to take advantage of certain features like radio (modem), volte if supported. It also depending on where you are reads your sim card and imei correctly.
no you do not need to back to stock to flash another rom just follow the rom developers installation instructions. If you have any questions, it is usually best to post in the rom thread as developer or someone who is very familiar with that particular rom can get the help you need.

Thank You very much for the explanation.
I do have a F-Version (International unlocked) So if I install new Modem will I still be able to use evrywhere ?
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!
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.
