I have some questions that I'd like to get some help with, I'm no means an expert, but I have several questions about installing custom roms,
1.Is rooting the same thing as unlocking a bootloader?
2.Can you flash custom roms without root? like the team viper mod
3.If you can, flash without root, what do you have to do in order to go back to stock rom?
The main reason I want to flash custom roms is because I wanted to see if there is an battery improvement, and I honestly wouldnt mind stock rom, but there are so many apps that you cannot uninstall that run in the background and take up ram.I cant stand the bloatware that comes with the AT&T version of the one x+

1. No
2. Yes
3. Have the bootloader unlocked and flash the factory stock rom / ruu. Note: once you unlock the bootloader there will be a flag that prompts it's been unlocked. If you relock it the flag will show relocked incase you are asking if you ever need to send the phone for warranty repairs.

hey, just wanting to clarify things before i start messing around with flashing. I want to install a custom rom, so ive read guides on rooting and installing recovery, as well as unlocking the bootloader. now i just want to know, if i am rooted and have recovery installed, do i also need to unlock the bootloaders to flash a new rom in recovery, or is that enough to do it. thanks for any feedback
-edit: i noticed looking at the custom roms, it specifies in the topic whether it is for a locked or unlocked bootloader.. so im guessing i just have to choose whether i want to unlock it or lock it depending on the rom i want
That is enough you don't need to unlock bl just be sure to flash a Rom for locked bl

I seen some people say something about bootstrap recovery but i was curious to know like what roms will work or if it really is possible to flash a custom rom while the boot loader is locked
Custom roms are possible, custom kernel is not. Imperium, mof3.5, rocko, homebase, and jokerskinny are your options. Mof3.5 is the only one still in active development.

I've done some reading and am still unclear.
So, if I want ICS and still keep my 4G I would:
1) Unlock bootloader
2) Install CM9, make nandroid backup
3) Install custom ROM
4) Relock bootloader
I am certain this has probably been covered somewhere and apologize for asking such a goofy question.

If you want ICS and 4g you for cant have it. In order to retain 4g the only rom you can use is a locked rom as already stated there are several in the development section.
4g =locked rom.

Is it possible to use custom ROMs without an unlocked bootloader?
Theoretically, yes. I did on my previous phone. A dev would have to cook a Rom with the stock kernel, etc.

could you explain a little more?
because i tried running cyanogenmod on my device but it showed up a security error, which i read somewhere is cause by a locked bootloader

Basically, when a ROM is made... It's either made from 100% scratch, or it's made with another ROM as it's base. For example...Paranoid Android used to be CM based... Meaning it used certain aspects of the CM ROM, but with the look/feel/features of it's own. So for this to work ona locked bootloader, the ROM cooker would have to use Stock as their base, and build up from there... I'm not a developer, so I can't go into extreme detail on this, I'm sorry.
But to properly answer your question... Yes, it is possible to do this... Will it happen?? Probably not, unless someone takes the time to port something over.
You got a security error, because CM changes things from the Stock base... So since it's not build from stock, it won't work unless the bootloader is unlocked, OR unless someone rebuilds it with the stock ROM as it's base.
For anyone else reading this... I hear MIUI is relatively easy to port onto a stock base...
okay. last thing. what 'changes' does the locked bootloader detect that it shows up a security error?
Boot.img has to be signed by LG. Not signed= security error. There is probably more to it than that but that is my understanding.

So, do you think it might not be an unnecessarily tough and time consuming job to port cyanogenmod in such a way that it would work on a locked bootloader device?

It's do-able... But may be pretty time consuming... If you have never ported before, I suggest starting with MIUI v4. From what I read, it's relatively easy. I know for a fact that MIUI, if ported properly, will work on locked bootloader, as my previous phone ran it with locked bootloader.
There is a workaround here. http://forum.xda-developers.com/showthread.php?t=2099238
Artas and markolino had CM9 working on locked bootloader P760. Anyone interested in trying to port a ROM this way should definitely check out that link.

I have a doubt reguarding bootloader unlocking.
It is possible to flash custom recovery using fastboot, and then flash any rom using recovery.
Then is there any need for boot loader unlocking specially??
I flashed recovery using fastboot mode without any special steps of unlocking bbootloader.
And plz tell what is the good way of flashing recovery- through stock recovery or through fastboot mode or terminal or certain tools(mtk)
I have rooted my phone oneplus x using kingroot.... It is rooted.... I have checked it with root checker.... I have installed TWRP on my phone too... N i want to flash the paranoid android 6.0.1 on it.... I have downloaded it along with gapps package........ Now i want to flash ut but i am in doubt wheather it will flash properly because i haven't unlocked my bootloader..... So will i be able to flash this rom without unlocking my phone???
Hi. I basically don't won't to unlock because you have to give your details to Sony which means voiding the warranty.
Can I still run custom (AOSP based) ROMs?

No. Custom ROMs require custom kernels which need unlocked bootloader.
However, the stock Sony ROM is pretty good.

"Pretty good" is not good enough for me. Maybe it's possible to somehow "patch" to bootloader so it won't check kernel at startup?
Since with root access you can probably overwrite anything (right)? And the bootloader already knows to allow booting modified kernels when state=unlocked.
Maybe one of the master developers here can hack the bootloader to make it behave as unlocked?
Ist it possible after modification to set the SGP311 back to 100% original ?

How to root (with links) is explained on my thread here: http://forum.xda-developers.com/showthread.php?t=2751432
Also, much of the "HTC specific" lingo is explained here: http://forum.xda-developers.com/showthread.php?p=52484527
I would suggest reading up (and making sure you understand all the terms and processes) for at least a couple hours before trying anything on the phone. I do this every time I buy a new device, even having own quite a few HTC phones. In fact, I usually start reading and researching before I have the phone in hand.

also is there a way were i can go back to stock when i need to thanks

If your talking about ROM, then take a full backup of your ROM before flashing custom ROM using titanium/nandroid etc.
Or if your talking about root,
Just unroot using unroot apps from play store or the respected app you get after rooting.

As the above reply stated, it depends on what you are talking about.
If you just want the stock ROM, recovery, etc. one option is to relock the bootloader and just run the RUU. It will return you to stock software. The only thing not "stock" will be the bootloader will say RELOCKED instead of LOCKED. You need s-off to make it say LOCKED again (after unlocking it).

so this is what i want to do i want to unlock bootloader then root which i know how to do but i was woundering would i be able to install this rom http://forum.xda-developers.com/att-htc-one-m8/development/rom-sd-4-0-sense7-port-sdkernel-t3062367
would i be able to install that rom soon as i am done unlocking the bootloader and rooting or would i have extra stuff sorry for the dumb questions

You should be good to go, then. Just unlock the bootloader, install custom recovery and flash the Skydragon ROM you linked.
would i need to be s-off and would i be able to go back stock and relock the bootloader with s-on again sorry for the manny questions i am new to this phone

You can return to stock with a RELOCKED bootloader with s-on.
You do need s-off if you want to make the bootloader say LOCKED as it was from the factory. But the only reason to ever do this is for warranty purposes. And if you bought the phone from AT&T, you should note that your warranty is through AT&T, not HTC. And AT&T doesn't give a crap if the bootloader is unlocked, or whatever (folks have even successfully sent in phones for warranty with custom ROMs on them).
If you are seeing warranty service through HTC (you didn't purchase from AT&T) that is another story. But that is the only reason I'd bother going back to LOCKED.
In normal usage, I recommend leaving the bootloader UNLOCKED as it give you more flexibility to flash ROMs whenever you want, etc. The only reason IMO to relock the bootloader in normal usage is to run the RUU.
S-off is nice have if you want to flash radios, modified hboots, and some other things (you also don't need to relock to RUU with s-off). It certainly doesn't hurt, and some folks like to make the phone as customizable as possible right away. In fact, I did s-off to the phone the second day I had it (although s-off was free back then). But for you, its not strictly "needed" at this time unless you want to do the things mentioned.
so heres the thing again sorry for the manny questions i am just making sure if i do this everything will work so heres the thing the rom i linked if i were to flash it will my at&t sevice work since it would be a different baseband
can you link me the latest twrp recovery for the at&t htc m8 so i can flash once i unlock the boatloader

The baseband isn't determined by the ROM, its determined by flashing a different baseband/radio (which requires s-off).
There are some folks that have had issues on AT&T's LTE network using some custom ROMs. Namely, not receiving or sending voice calls while on LTE. But this seems somewhat random, and not the ROMs fault per se; but probably changes that AT&T is making to their network. The most you can do is flash the Skydragon ROM, and if you have problems, try another ROM or revert to stock.
Make a backup of your stock ROM with TWRP before you flash anything, to be sure you have something to revert to if you have problems. This is good general advice before you flash any custom ROMs, root mods, etc.
I'm using the ROM your linked (Skydragon Sense 7) on AT&T, and it works fine for me.
