Don't need ROM, but want Root-> What's reqd? - Galaxy Note 4 Q&A, Help & Troubleshooting

I have recently been told that unlocked bootloader is not required for ROOT.
If I get N4, I'll want to root, but don't care about ROMS. So, I had been thinking I would likely need to got with TMO phone on AT&T, rather than AT&T, due to unlocked boot loader (although I planned to wait to be sure it is unlocked).
But, given that unlocked bootloader is not required for ROOT, I'm wondering if I still need to look at TMO. I suspect should just wait and see what shakes out.
Interested in hearing anyone's thoughts on Rooting possibility for the N4,

Can an ulocked G1 be locked by upgrade or root?

If I have an unlocked G1, can anyone tell me if I root my phone and update to some of the firmwares posted hete (RC33), is it possibel that my phone becomes locked again? I now have RC19 and the phone is fully unlocked, but I'm afraid it can become locked again if I root it or flash it with another firmware. I have enough technical background to do the rooting and flashing as I have expoerience with windows mobile, but this is something new for me. Btw - i totally love the G1 and regret not leaving windows mobile.
The Sim-Lock is in an area of the phone that can not be "flashed' by the user. You are good to go!
Thanks a lot for that !

I have been looking for this answer, as well. I have a brand new g1 that I traded my 3g iphone for. It's unlocked and on my AT&T account with no problems. But I had my iphone modded to the hilt and so of course I want to do the with the g1. That was the answer i was looking for!
Anyone else?
Yes. Please, anyone who has rooted and upgraded their UNLOCKED g1 , share experience. It may seem like a stupid question to some of the "advanced" users
bt remember - you weren't born with knowledge, so share it!
For example - an ulocked Iphone can be locked when upgrading so are you sure that the G1 won't lock as well!
What do you mean unlocked? As in sim unlocked, if so it can not be locked by upgrading software.
If you mean unlocked as in you have access to root. Then yes, but that is why you use JF's firmware.
alright ive got a rooted rc33 and im on at&t, ive upgraded from rc30..
so even when you upgrade you're good to go
I mean sim unlocked
I mean what unlocked means - SIM unlocked. My device is rc19 and came unlocked for any sim cards. I haven't done anything with it yet - root or upgrade and I wanted to ask if it's safe root and upgrade a sim unlocked device.
I was concerned it may become locked again because I don't know anything about the unlocking process on the G1 - I know there is a code that's generated according to the IMEI and tahat's about it but I wanted to know if this code can be erased by flashing newer firmware. I have read the steps described on this site for root and upgrade and I plan to do those with my device but I wanted to gather some opinions first. I hope this topic will be useful to others who have bought the G1 unlocked and are concerned.

youre safe to upgrade and root, ive done both and mine has stayed unlocked..
Ok. That sounds encouraging. I recall that there were more than one ways to unlock the Iphone. Is it the same with the G1 - I know the main way to unlock
it is by entering a code but I also know there are HARDWARE unlocked devices (as the developer edition of the G1) - Is yours only simUnlocked or is it hardware unlocked too? I'm sorry if I'm asking too much, but I don't want to pay 30$ to get an unlock code again.
It's not like the iphone. The iphone is has to be 'unlocked' by hacking the firmware, since apple have never released any legitimate way of unlocking it, and seem to take great delight in re-locking 'unlocked' iphones every couple of months (this is one of the reasons why my iphone sits at home gathering dust).
The G1 has a standard unlock code, just like just about every phone on the market. Once that code has been entered the phone is unlocked permanently. There's no such thing as a hardware unlocked device - it's merely never been locked to a provider. In the same way if I buy a 5800 from Nokia it's unlocked but it's no different to one got on contract, it's just never been locked.
Google don't care much if you run JF firmware or something you cooked up yourself... they give away the source code so you can do just that.
Thanks.
So entering the simunlock code is irreversible process, having nothing to do with the firmware. That's what I wanted to hear. Thanks guys.
Successfully rooted, upgraded to Jf RC33 with multitouch, put apps on SD and very happy now

Any Info On locked or unlocked bootloader?

Basically, the thing that will help me decide if i get it is if the At&t version has a locked boot loader or not. The At&t and VZW S4 are locked and a Pain for us Who like to tinker with our devices I was lucky to get an unit early with MDL firmware and have the benefit of being able to use Loki to have my way with it but but those with MF3 versions are SOL and there is not even an ODIN package to restore to factory if you brick.
Since the MF3 has been successful in holding back modification Im pretty sure AT&T will do something similar with the GN3. There is always a hole that can be exploited nothing is perfect but MF3 is messing up the advance in the GS4 ATT. I Like to mod as soon as I unbox.
So as soon as any info is available on the Boot loaders please share it. If the bootloader is unlocked on the AT&T One I Have A brand new Unopened SGS4 AT&T with MDL Soft ware Im Going to sell to get the GN3.
i would put very good money on both being locked AT&T might have a better chance to get an unlocked one but as much as i want verizon bootloader to be unlocked im sure it will be!
And if it's locked the only alternative we have is to get unlocked non-lte version?

[Q] OEM unlock on Note 4?

(my browser spazzed and I lost my last post if it shows up as a double ignore the other one!)
I'm new to Android and finding it confusing so thanks for the help so far!
I have a 910F Note 4 on Lollipop and want to root it to get rid of bloatware and possibly stop ads (if I can convince myself it's ethical) btu I *may* want to custom ROM it later.
So far your help and my reading have taught me this:
-- I can root using chainfire in order to get rid of bloat and block ads
-- If after rooting I later want a custom ROM or Xposed I'll need to get custom recovery in which case I'll be able to add CWM or TWRP later to my rooted phone
Assuming the above are true (if not please tell me!!) my question is this:
What on earth is oem unlock/bootloader unlock? In my reading I've come across people talking about this and it wiping the phone. I can't find an easy answer online. If I root +/- do CWM/TWRP will that automatically do OEM unlock or are they different things? Is bootloader unlock a different thing too? I'm confused! Will I need to root AND custom recovery AND oem unlock AND unlock bootloader?
Thanks in advance!!!
Some devices come with a locked bootloader, where you may be able to root the device via an exploit, but you can't change lower level software (ie kernel and/or recovery)... unless there is an unlock method for the bootloader.
The devices that do have a locked bootloader can be locked by the manufacturer, or by the carrier. That's the difference between the two. Either way the bootloader is still locked, only difference is who called for the locking.
For example, note 4 on tmobile does not have a locked bootloader, however, note 4 on at&t does. That decision was made by at&t, not Samsung. As far as I know, the at&t variant does not have a method for unlocking the bootloader yet so there's not much development for the device.
Compare to nexus devices, where Google automatically has the manufacturer lock the bootloader, but it being a development device, it's the easiest bootloader to unlock. It's literally a one line command in adb. HTC devices are locked but you can get an HTC dev code to unlock it from HTC.
I hope that makes sense. The best way to determine if your device has a locked bootloader is to visit the development forum or the general/Q&A forums for your device. If you have a locked bootloader and there is an unlock method, you only have to do it once (until you update or relock your bootloader). Some locked devices never get an unlock method. It designed to maintain the security and integrity of the device, but it also prevents user tampering.
Thank you for your thorough reply absinthesummer, very helpful.
However I'm still a little confused. My reading suggests to me that T-Mobile (910T) is *rootable* and the AT&T version (910S?) is not *rootable* but I'm in the UK and don't use these providers I use EE. And so I have the international variant of the Note 4 which is the 910F. I don't see a subforum or help for the UK EE version of the note 4 but as it's the 910F I assume that's the one I need to search for and not worry that EE will have put their own lock onto the 910F??
Now, because this happens to coincide with what you are saying has a locked bootloader or not, am I to assume that whether or not something is rootable is the same as whether or not it has an unlockable bootloader? i.e. is something only rootable or not because its bootloader is unlockable or not? If so therefore am I correct to assume that as the 910F which I have is rootable that it is also bootloadunlockable? And furthermore am I correct to assume that the very process of rooting itself unlocks the bootloader? Or perhaps in the case of the 910F it doesn't need to be so is even easier than Nexus devices? i.e. I just simply root and that in itself mean bootloader is already unlocked (and I am assuming that oem unlock is the same thing?)
I'm getting myself in a muddle I think!
Hehe it's totally cool, and yes your carrier could put a lock on it but that's incredibly rare in Europe due to frequent traveling between countries and the need to change Sims and carriers often... or at least that's what I've been told. The US carriers who lock their bootloaders are typically GSM carriers who do not expect you to need to root/carrier unlock/whatever. It's a control thing imo.
Anyway, your note 4 does not have a locked bootloader. If you check the development forum for your device you will see plenty of roms and guides and directions for rooting. That's usually a good indication that a device is unlocked (and those anticipating the release of new devices tend to get lock information prior to release, so they know which device they intend to buy).
Anyway, since you don't have a locked bootloader I wouldn't worry about it... that reminds me of a device I had for about a week, the LG L9. It had an oem bootloader lock but the international variant did not. We could root it & use a specially designed recovery with the bootloader locked but we couldn't flash a custom kernel (with a custom rom). They figured out that we could flash the international firmware and unlock that way, but it would make our display backwards (mirrored) and while that could be fixed, we would never be able to revert the boot screen. Now that's way too much trouble to go through just to unlock a bootloader and I did end up returning it and getting an s3 instead.
Bootloader locks are no fun, but they are not often placed on international devices for various reasons, so really I wouldn't worry about it too much.
If you get a device like a Google nexus, or an HTC that has a known locked bootloader, the bootloader and unlock method will be specifically mentioned in the routing guide. I hope that helps.
One more thing: rootability and locked bootloaders are not mutually exclusive, sometimes you can root devices with locked bootloaders and sometimes people will come up with ways around them (ie note 3 has safe strap recovery that runs parallel to stock recovery) to be able to use custom roms. However, if no exploit is found and there is no workaround, development will stall until one or both of those things is found. You may be able to root a device with a locked BL, but you may not be able to flash custom roms/kernels without a workaround. What I meant though is if you see a popular device with very little development, that's probably due to a locked bootloader and not having found a way around it yet. Most guides will explicitly mention the BL though if it's something you need to do
Yet another thoroughly helpful and detailed reply. Thank you very much indeed. You're a star!

[Q] im new to the forum plz read my question help!!

I have a verizon samsung galaxy note 3 as many already know after 4.4.4 was released verizon locked the note 3 boot loader so users cannot down grade back to 4.4.2 and the only successful root process that works is on 4.4.2 at this time as far as I've researched so my question is if I were to pay verizon the sim unlocking fee and switch to a carrier that has a known properly working root process, in theory would this work. ? Any feed back would be great. Hoping this will work??!! If any thing I've said is confusing please reply and I'll try my best to reword it.
You're assuming that when you pay the fee that verizon will flash you with an unlocked boot chain. Don't think it's possible. If I'm not mistaken, some of the trust zones are flashed then locked with a physical fuse.
....
So paying the unlocking fee then say you buy a BYOD (bring your own device) kit from t-mobile, straight talk etc, activate the phone with the new carrier (preferably a carrier that currently has a root method that works) then proceed with rooting said device?
Again I'm new to the forum as well as new to the concert of rooting, flashing custom roms etc so please respond in laymens terms
Idk if it could work, I'm just trying to explore any possible solutions to the problem of when android 4.4.4 was released (verizon released theirs with a locked bootloader and if my reseach is correct, there are root processes working for android versions after 4.4.2 on other cell carriers.
So what I'm trying to figure out is if I found a root process that is known to be working on for example (a root process that works on t-mobile, sprint, at&t etc)if I paid to unlock the damn sim and activate the SM-N900V on a cell carrier that so happens to have a working root process, what is the likely hood of it working?
Or
Will it be a complete waste of time, effort, and money to atempt?

You are confusing 2 different types of "unlocking".
Sim unlocking is not the same as unlocking a bootloader.
The locked bootloader will not be unlocked by Verizon.
The locked bootloader will not allow you to flash a custom kernel or system and prevents the easy rooting methods. Unless someone finds a root method, you will not get root on that device.

All things root and Bootloader?

Hi Friends,
Hope you're all having a great new year. So last time I was lurking the S7E forums, we had a leaked Engineering Bootloader that was used to acquire root on all US Snapdragon models, albeit, with a lot performance issues and etc.
I came here to glance as well as all other variant forums for the SD model and now we have Root for every model, with even ROMs being baked like the Echo ROM for Verizon, Sprint, AT&T models, usually the toughest to achieve these things on. I'm trying to read through the forums, but I fear I'm missing the details, that will help me pull the trigger for getting the device or not.
Can one of you very experienced, knowledgeable, and kind members educate me on the latest?
1. Do we have unlocked Bootloader and Root for all US carrier S7Es? How is it done? I use people using Flashfire. So no TWRP?
2. Does this process still trip Knox and render Samsung Pay to never be used again on the device?
3. If I bought the Verizon variant, for example, can I root, unlock Bootloader, and etc, and then return to stock, to return to the store in case I don't like the phone?
4. Xposed Framework working for all models?
Much appreciate your responses, any and all of them in advance! Thanks!
1. No public unlocked Bootloader on any US variant. Flashfire works but no custom recovery
2. Right now with eng Kernel and custom(ish) roms like Echo don't trip Knox since it is still the U firmware of the s7
3. You can root and jump to roms like echo or other stockish roms and return to normal and return to store but no unlocked bootloader
4. Far as I know Xposed works on most if not all (I have mine on and Att variant running Echo) It is installed/Flashed via Flashfire and is a custom version.
Since we still need the leaked Eng Kernel we still have massive performance and battery lose. There are guides to alleviate these issues but its still not as good as stock. Even roms like echo require it for root. So remember that before you jump in
1. Do we have unlocked Bootloader and Root for all US carrier S7Es? How is it done? I use people using Flashfire. So no TWRP?
There is no bootloader unlock for the US carrier variants of the device as of yet, senior forums members are guessing there probably won't be, either. What is being done successfully is rooting via an engineering kernel. Visit the carrier-specific sub-forum for your S7E model to ensure you're using the appropriate method and files when flashing. Flashfire is being used after the fact, for things like xposed. There is no custom recovery option for any of the US models that I'm aware of.​2. Does this process still trip Knox and render Samsung Pay to never be used again on the device?
None of the outlined processes will trip Knox, as they don't modify or replace the bootloader. Samsung Pay should still work fine when rooted, as far as I've read.​3. If I bought the Verizon variant, for example, can I root, unlock Bootloader, and etc, and then return to stock, to return to the store in case I don't like the phone?
The Verizon variant has some of the better documentation and support for root, but AT&T and T-Mo carrier models can also be rooted. I'm currently running the firmware for the T-Mo variant on my AT&T model and loving it. I'm not rooted, as the engineering kernel is absolute crap in terms of performance/battery life balance, but it is a fluid stock experience w/out bloatware.​4. Xposed Framework working for all models?
As far as I know, yes.​
