[Q] [Newbie Question] Details about rooting

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:

Out of the game for a while advice welcome

The last time i flashed a rom was about 6 months ago and the last time i had to get my hands dirty in a root and recovery process was even longer, probably as much as 2 years back with my old S2.
With this in mind i was hoping for a little guidance on a couple of things.
1) I'm not too concerned with triggering knox that i heard could be a problem in the early days for the note 3 as it's nearly 2 years old but I'd prefer not to, what is the best way and the best order to root, flash recovery and then flash a rom?
2)i know there isn't much love for people asking what is the best rom but what i would like to have is a stable rom even if it isn't the most recent and i do like touchwiz. However i do like the idea of extra features and tweaks. So, are there roms around that meet these requirements?
Cheers guys.

There are ROMs.. but Xposed is still not stable for Lollipop Samsung phones...
I'm not a fan of Touchwiz either but Lollipop Touchwiz is awesome (coming from a CM Fan)
Also ROMs like AryaMod are promising

cheers mate.
any other advice for the rooting and recovery processes from anyone?

You are not out for long enough to forget stuffs Welcome back anyway.
Rooting can't be more easy. Just flash any custom recovery (TWRP/ Philz), and flash the SuperSU zip package which can be found in Chainfire's website from it, https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip
Done, you are rooted.
And for stable ROMs, well some are out there, but my favourite is AryaMod. It is based on stock TW ROM and comes with lots of customisations. If you are looking for purely stock based ROMs then just download those cooked ROMs by Alexandar (pardon if the spelling is wrong), they are as close to stock as you will get. And I don't like S6 based ROMs, I have a Note 3 and I want it as a Note 3, but there are few out there which will give you some S6 features. But the ones I mentioned are purely Note 3 based, you won't find any other phones' feature in them

1. I triggered Knox ages back so haven't kept up on things but if you flash a custom recovery, AFAIK you WILL trigger it. There are ways to flash custom ROMs etc without triggering Knox but I think you have to flash a pre-rooted ROM. Do some reading around - I've seen a number of threads about it.
2. I am currently on Temasek's CM12.1 ROM and have been for some time. I occasionally try others but have always come back to his - it's everything I like. Even on stock though, I run Nova launcher. For a stock-based ROM I'd recommend Sparx's Alliance ROM - I used it for months and it is easily the most configurable ROM I have seen - you don't need Xposed or other app to mod things, it's all built in.

You'd be surprised how much i could forget haha
So, would it be - 1) root (which method and how?) 2) flash recovery (which one and how?) 3) if I'm to use arya rom it says I'd need a stock lollipop installed first so would i do this before the root and recovery (again which one and how?)
Thanks guys for advice and patience.

hi and thanks for the referral to Arya. i see it mentions having to come from an existing stock lollipop. could you take a look at my post just before this one and see if you can guide me a little as i dont want to brick my note 3 by doing something either wrong or in the wrong order. thanks for your help.

1,2- Root: Simple as I said before. Just head over to Development section and find TWRP recovery. Flash that via Odin. Then go to Chainfire's website, to download the SuperSU zip package, 2.46 I believe is the latest version. Have that zip package copied to your internal or external memory, enter Recovery (I am sure you remember Vol Up + Power button combo will help you to enter recovery) and flash that SuperSU zip file. Just reboot the phone and you are now rooted.
3- Yes, you will be needing to flash a stock Lollipop ROM to be able to use Arya. I am not sure but I think its because of the bootloader. If you want to flash a stock ROM, just head over to sammobile.com and download any Lollipop ROM you want and flash it via Odin. Then download Arya ROM, it will be a zip package, and install that from TWRP, just like you would flash that SuperSU zip for rooting.

Cheers mate, i think I'm nearly there. Flashing the stock lollipop will wipe out root won't it? Do is it best to first flash the stock lollipop, then flash twrp then root then arya?
Lastly, when i looked on sammobile there were many different regions of it. I'm in the uk on an unlocked international model which i believe is btu. I know btu hasn't had it yet so which one is best? I know I'll be flashing arya over it but would like it to be the right one as i might try it out for a few days before flashing arya.

Yep, you got it right, you should flash the stock Lollipop ROM first, then flash TWRP, then root the phone (SuperSU zip package from recovery) and then flash AryaMod. That way you won't have to repeat any steps, cause flashing any stock ROM will restore stock recovery anyway, but I am sure you've already figured that.
About the ROMs on sammobile.com, well I can't really say which one you should download. I once downloaded a German or UK ROM (can't recall really) and it wouldn't flash on my UAE Note 3, someone told me that mine is 32 gigs phone and that ROM was meant for 16 gigs phone, since then I really didn't put much thought about those ROMs anyway, and obviously I had found Arya by then. You can ask in on the UK only topic in general section, they should be able to help you. The ROM from sammobile which worked for my phone was Polish Lollipop ROM, but again, it worked on my phone, so you get the point.

Questions about installing custom rom and need rom suggestions.

Hey guys i want to install a custom rom for my t00j-d. I searched about unlocking bootloader and things like that but i couldnt find something useful. First off all i have latest stock rom (lolipop) and its not rooted so do i have to root my device first then unlock bootloader then flash rom? And which rom is good at the moment? My priorities are battery life > performance > visual.
thanks for reading and answers

you can root zenfone without unlocking bootloader and if you wont flash rom backup your imei using terminal and then system using twrp or another recovery

i have been looking around and can not find any info on what i want to do. so i am just going to ask and see if anyone can help. hope ive come to the right place.
about a year ago i purchased a blu studio 6.0 hd(d651u). it came stock with kk(4.2.2 i believe. can confirm if needed.) i pulled the stock firmware using droid tool. so i do have the original rom and scatter file. the lollipop update was available so i updated. afterwards i ran the updated rom through SuperRs rom kitchen, rooted, de-odexed, debloated... afterwards when i was theming the apks and was almost satisfied, i dropped the phone and it broke.. so i purchased another one. same make same model(d651u). only thing i see any different is that this new one came stock with the same lollipop rom that my old phone had updated to. so my question is this. can i use the stock rom and scatter file that i got from my original device to restore the device i have now in case anything goes wrong. im trying to find out if i can safely skip the whole rom pull step and jump right into getting my custom rom onto my NEW phone. i know i can use my old rom, i just wonder if i would be able to restore a brick with my original rom pull because they are the same device, just manufactured at different times. any feed back would be GREATLY appreciated. thank you

no, you should not use the backup from another phone to restore your new one. and you should post in the section for blu studioinstead of here, the info you get here might be inaccurate

How to return to original firmware from CM13

Hello everybody,
I have a Moto x play running CM 13. I followed the process listed somewhere in this forum and successfully installed cm 13.
Bad news is my laptop got stolen at uni. I had installed Motorola drivers and all that stuff in there, so now I'm wondering if I can go through this process without that laptop. I hope I can.
I only have the cellphone and I would like to return it to its original firmware so I can sell it.
Is there a safe way to do this without "bricking" my phone? I'm not very well versed in these processes and managed to install cm13 only because the procedure was very clear. I hope you guys can help me!
The original carrier is Iusacell (Mexico), although the cellphone itself is unlocked and takes any Sim.
thanks in advance!

to flash original firmware without PC you can use Chainfire's Flashfirehttp://forum.xda-developers.com/general/paid-software/flashfire-t3075433, however - it's still kinda experimental, needs some knowlege, and I'm not really sure if it supports our device. Reading through its thread may give you some clues. This will not revert your phone to out-of-the-box condition - that would take relocking your bootloader and PC is needed to do so (warranty will be still voided anyway). So maybe just try flashing some stock ROM in TWRP. The procedure will be the same as flashing CM.

I feel more comfortable with the second option. I found this github with MXP ROMs for my country and carrier: https://github.com/motoxplay/stock
I honestly can't remember if I had it at the beginning with Android 5 or 6. What happens if I flash Android 6 and it originally was 5? I suppose I should make a backup "nandroid" first.
BTW, can the bootloader be locked again via a new PC?

Flashing newer firmware won't break anything, it's a normal update. Worse thing would be if you tried to flash Lollipop over Marshmallow.
Making backup is always a good idea, do mind however, that flashing full stock firmware means overwriting your TWRP with stock recovery. Also, be aware the files you linked are actually firmware and not TWRP flashable zips.
And yes, you should be able to relock bootloader with original firmware.

Baseband Collection/ Switching Guide

I really think there should be a thread on XDA with tested methods to switch baseband as a lot of people face trouble with GPS etc on custom ROMs. Ideally we should be having a collection of TWRP flashable zips instead of having to install stock firmware via tools like Miflash and then doing everything from the beginning.
This zip from Davideavinavil is TWRP flashable and it works perfectly for me. It doesn't improve things drastically from stock Marshmallow Indian ZUI baseband but would be great for if your GPS is not working or something.

To get the baseband from latest Indian ZUI Nougat Beta follow these instructions from zukfans by Magz Heaven. Tested on my own phone which previously had the above Davideavinavil zip flashed and is now on M8996FAAAANAZM-1.76387.1.92759.1. I wiped everything TWRP then flashed this in fastboot and then went back into recovery and flashed ROM + GApps. If you want to run this in Linux open the bat file as text and use the same fastboot commands with those files in your pwd.

1. Will bootloader be locked again after flashing baseband?
2. Do I have to flash ROM after flashing baseband?
3. Does bluetooth connectivity depend on baseband?
Thx

1. Yes its possible that your bootloader gets locked after flashing. If you do it wrong and doesnt check it after first reboot you can brick your device.
2. No you dont.
3. Someone said when you only flash the NON-HELOS.bin file you can get problems with bluetooth. If its right I dont know.

Thanks for your response. Only reason i asked about bluetooth is because only ONE custom rom works for me bluetooth wise. I'm unable to connect to my cars headunit with any rom except resurrection rom. Would flashing a modem help this? my modem is 9-00026-M8996FAAAANAZM-1.63821.1

Flashing custom roms shouldnt change the baseband. Does connecting work on rr with this baseband? Do you have problems with other bluetooth devices except your car?

Sorry I probably didn't explain that the best. Flashing ROMs doesn't change my baseband but I'm wondering if changing my baseband will fix my Bluetooth problems. Yes RR works with my current baseband and my Bluetooth works with every device I've tried, on flashing to a different ROM none have worked sadly. I've tried to ask around if other people have issues but they all say their BT is working as it should haha

I flashed this zip onto my z2 plus and the phone has stopped completely. Its not booting nor am i able to go to recovery.
It flashes ZUK message and then goes silent completely.
Have i bricked the phone? Can i recover it?
Thanks

Will this baseband work for the UK? Sorry if this a silly question
