[Q] it is possible to...

Sorry, I'm new to this so sorry if this seems dumb.
So i bought the phone from rogers and immediately updated to froyo 2.2 official release by rogers/samsung.
I read about all the hype online about rooting and custom roms so i decided to give it a shot.
I used the superoneclick method to root my phone and it was successful.
I then used "rom manager - clockworkmod" and created a restore file before i did any flashing to my phone.
after creating a backup, i went on and flashed to the cognition 3.04.
Now my question is. Am i ever able to get my phone back to its original rom, kernel, and modem? the reason i want to know is because i might need to get my phone replaced due to some technical issues with the phone.
Also, does the backup of my phone after rooting play a part in any of this? if so, how?
Im sorry if there is already a post like this one. Its just that i couldn't find the answer through all the hundreds of pages of threads and replies, so I thought it would be easier to post a here with my specific question. Thanks.
regards,
danny

It guides you through the process of going back to a stock ROM. Btw, I've used it and it works.
Good Luck!!

Thanks for that. Do you think Odin is the only way to do it or do you think i can use clockworkmod

Do I not use that link in general, or just not to use the firmware given at the bottom? the steps are correct though, no?
also from my searching.
i can put my phone back to my backup point (just after rooting) through clockworkmod. Woud this change my rom back to stock from? how about kernel and modem and all that? would that all get reversed back to my backup point? meaning it will basically be a stock phone. But I think also read somewhere that my kernel and modem does not get changed back to rogers original one. is there a way to do it?
I then found this link: http://forum.xda-developers.com/showthread.php?t=846501
that says i need the original rogers rom for the captivate by the links there no longer work for download. Also on that thread, it was mentioned that the AT&T logo will still come up on startup, which would not be a good idea if i had to send my phone in for warrenty.
I then looked at : http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S/SGH-I896
Here it tells me to flash to a i9000 before i reflash to a rogers firmware in order to remove the at&t logo. it also provides me with a link for the " Official Rogers Stock ROM ", but according to somebody on the first link i posted here, it isnt the "official rom"
Any ideas?

This is where I got the stock 2.2 file from http://forum.xda-developers.com/showthread.php?t=905042.
Edit: I have flashed a bunch of times and have never got stuck with the AT&T startup after flashing back to stock with the odin file.

Thanks. Do you know if my kernel is going to go back to stock too or is it going to remain the same as the custom rom one?

If you use the odin file the kernal and modem will revert back to stock.

Thanks. So im assuming now that the only time my kernel and modem wont go back to stock is when i flash with CWM. correct?

I haven't tried using the CWM file in that link so I'm not sure if it contains the kernel and modem. As far as custom roms go most if not all come packaged with the kernel and modem of choice.

So.. When I do a "master clear" from http://forum.xda-developers.com/showthread.php?t=731989...
Would everything be wiped? I read somewhere that when you do a "wipe" from your settings it only clears user settings or something. What would a "wipe"
from the recovery menu do?
I flashed to a different rom today thinking it will help my battery issue. When i am flashing from one rom to the next, i do a restore back to my backup before i flash to a new rom. Is this the correct method? or am i supposed to wipe beforehand? The reason i ask is because this is my 2nd rom and my battery issue still seems to be there. I tried other methods of fixing hte battery but nothign seems to work. When i looked into root explorer, i see that there are a lot more files now everywhere, than when i first started. would some of them be from my previous rom? if so how do i remove them?

[Completed] S3 ATT Like to know how to unlock bootloader, root the phone, and install custom ROM

Hey first time posting on xda devs and would like to know how to unlock bootloader, root the phone, and install custom ROM.
Now I have spent entire day backing up and searching the different people root but if someone can help me and point me in the right direction that would be great.
So I have a S3 from ATT Model: SGH-I747, Version: 4.1.2 JellyBean, BaseBand Version: I747UCDMG2, Kernel: 3.0.31 - 1300972. It is a stock ROM, I have never done anything to the phone at all before.
Now I will admit I followed a youtube video call "How to Root AT&T Galaxy S3 SGH-I747!" by High on Android and I did everything in the video. I used odin v1.85, I did the PDA to the CWM.tar file, phone rebooted and I added the CWM superuser file and that is when I tried to get to CWM recovery mode and all I got was the phone's default recovery mode and not the CWM one.
From what I understand I believe I need to unlock bootloader first, but again this is a my first doing this and I hoping someone can point me in the right direction. Forum post state that you should follow guides that is exactly the same to the phone you would like to install custom ROMs.
Honestly I would like to ultimately be able to install a recovery mode that works with my phone that I am able to create snapshot image of my stock phone in case anything happens or I would like to go back to my stock image (which I highly doubt if everything goes fine) and install a custom ROM (I know there are different ROMs if someone can point me to where I can check out all the custom ROMs and not necessarily install those custom ROMs that would be awesome) and finally get rid of ATT loading screen when booting up the phone and install a custom boot loading screen, but of course I care more about getting the custom ROM install first.
If anyone can help that would be great.

This rom is a stock rom and is almost 100% stock but it comes without dm-verity to avoid boot problems in case you want to preserve your custom recovery.
This rom is meant to be used in case of emergency, give a fresh start to your device, restore your device in case of corruption or just to play around.
I have tested this rom on my own device and everything is working properly.
Please check the specifications at the end of this op.
Requisites:
New assert-fixed twrp version forked from messi's twrp
Note: All the credit for twrp goes to @messi2050, this is just an assert revision of the current twrp made from messi. It will be deleted as soon as we get an updated version with the right assert tags.
Installation steps
Download the new assert-twrp version and flash it as you would normally do it.
Standard Wipe (factory reset) and Format Data are optional (unless you have a non-stock based rom installed already). If you want a full fresh start you should format data, reboot into recovery again and do an standard wipe x3.
Install the rom.

Please read requisites and download the new file using the new link.
With this new assert-fixed version of the current twrp made from messi we can now avoid issues flashing the original iPioneer Rom.
NOTE: This will only work on MetroPCS, not sure about tmobile, I will try to make it for both carriers...

I think you mean screenshot right??
I usually don't take screenshots on my stock roms, basicly because there is nothing new/fancy to show. It is stock and it'll look the same as when you buyed your phone, with the same default wallpaper and apps...
I take screenshots in my slim versions (wich I will start soon).

For some reason doing the Vol - and Power does the same wipe problem as in Messi's V1 of twrp for me. Am i doing something wrong?

Lgms210 custom roms
My name is red208 and I just want to know if there is a custom ROM for MetroPCS LG ms210 preferably like Resurrection Remix I also want to know if this stock
ROM right here is at all any different form the way metro does it? Im really trying to bypass the 8 gig hotspot restrictions that metro has so it can be a truly unlimited hotspot and i know the easiest way to do that is too just Flash a custom rom plz help me??!!?

You mean that you power off your device and the use the Volume Key and Power hit yes twice, right???
If that is the case you could try flashing DM-Verity or SuperSu again to avoid that little bootloop. Or you can just stick (like me) to do and ADB REBOOT RECOVERY.
Please notice that I never mentioned that the bug-fixed twrp was intended for this bootloop/reset issue, it just correct some asserts problems that block our devices from installing this rom and any other room with the right and original asserts.

Question 1: There is not at the moment, I will start with Leaneage OS after doing my slim version. I don't know how many time it will take as this is my second device and I am just playing around with it (my V20 give me more pleasure).
Question 2: Stock means Stock... Nothing new nor fancy, same setup, apps, etc.... I mention on the OP what this rom porpuse is.
Hotspot issue: not all the time depends on a custom rom, this is my first device with metropcs service, I don't know if they sync your hotspot usage with their servers. If they do you are not going to be able to bypass that. Any ways my slim version it would get rid of plenty of bloatware and it may work if they depend on the main app on the device.

The hotspot will be monitored regardless of if you're using a stock room or custom. The only difference being that on a custom rom, you won't receive a notification stating you went over 8 gigs. Once you hit the 8 gig limit, your hotspot speed will be slowed down.
Also, when you go over your 8 gigs of high-speed hotspot it won't reset at the beginning of your pay period, but exactly a month (to the day) after you went over.
So say your pay period is the 5th and you go over your limit on the 4th. You'd have to wait until the 4th of the following month before you get high speed back.

I was just about to ask if your slim rom would be a debloat, but now I know. So good look there.
Also, if and when you get down on lineage. I'll be more than happy to test, I had been working on it myself before I blew up my hard drive. So I'd rather help then be a sponge.

Im also willing to test.

Ufffff...
Ok guys... After several days testing / building the slim version I am getting really frustated and dissapointed...
Everytime something goes wrong there is no way to boot into recovery mode using hard keys, that only makes twrp wipe and reboot but not entering on the complete twrp options. So everytime that I flash the test .zip of the slim version and I get an error before actually booting completely into the normal system I have to go to Mocosoft (windows) and use LGUP to flash the .kdz and start from scratch all over.
I hate to have to reboot my laptop and use Mocosoft, I really hate not been able to reboot in recovery mode as in other LG devices with the hardkeys.
I guess is another limitation of the actuall twrp version that we have, maybe we will have to wait for an updated twrp version to avoid all this trauma.
Right now I feel like I'm done with this device, I have used LGUP around 15 times in 3-5 days just because I can no go into twrp.
If this is happening with a stock based slim version I don't want to think about building/testing lineageos.
If you know an option to go to twrp version after a corrupted/incomplete system tell me about please. I have used the followings procedure but not success:
1.- Hardkeys (just makes twrp wipe the system).
2.- Fastboot boot twrp.img (command fails).
3.- Flashing original twrp (from messi) and then the flashing back the bug-fixed twrp (forked from messi) and trying to reproduce the first boot taking out the battery and using hardkeys (no luck, still wipes the system and reboot by it self).
Sorry guys, I think I will stop for a few days... Maybe I need to go out and have a little fun and come back...

So now I can continue with the test and after that with Lineage if no body build it first... :laugh:

I hope you can success with lineage 14.1, i wasn't able to make it boot on the stylo 2 plus since ms210 and ms550 are almost the same if you managed to boot it then I'm sure it will work on the stylo too, good luck.

I know it's really late, but I was just gonna say build a version of your rom with the flags for Messi's twrp and just use that to flash.
Either way, I'm glad you managed to sort the shiz out and I'm wishing you the best of luck with development.

???
I don't get it?
You mean the asserts right?
I haven't test the new twrp version of messi (no free time), so you are telling me that the new version still have the wrong flags?
I usually don't remove the CORRECT flags from my roms (a Tmo user could flash the metropcs and cause a brick/softbrick for example) to avoid user's mistakes/misread...

The new version has the correct flags. I never said it didn't.
I'm saying that a twrp can be created with unified flags allowing a room to be shared between devices without having to build between the lv3 and the aristo. Sorta like what had been done with the LG Leon a couple years ago.
Instead of using the h or Ms flags relating to model number, you can use the consistent board config as the basis.
Either way, the only way someone could brick or soft brick from this method is if it were like the S4 situation where you have to flash the carrier specific kernel version for the device. Like using the At&t rom on the Verizon s4 will cause a soft brick until you flash the Verizon s4 kernel.
This is only just an idea in response to you having to go back and forth (before you got the updated twrp) on recovery versions during your tests

OP updated to link and point to the new and updated twrp version from messi.
You guys no longer need the bug-fixed twrp version as before.

Can you do me a solid, sorry if I'm turning into an annoyance. Add "lg aristo" into either the thread tags or into the thread name itself. It'll add the thread into the Aristo board for easier access and make this easier to find. I recommended your rom to another user who had no idea what I was even talking about. (So I shared the link if you don't mind me doing so)

Then it would be no Problem just downloading this and adding it.
Edit: This stock firmware dose have the stock recovery dosen't it ???

Well i would also like to remove twrp because i can't find the needed zip files in order to root my device twrp failed me in that retrospect.
Plus now i am wondering what use it could have when stock recovery is not that bad actually.
Very disappointed i did all of this in hopes of rooting this phone and i voided my 1 year warranty also when i flashed it my phone was very unstable i had to wipe it.And all i got was nothing but atleast the phone still works.:good:

What exactly happened? You provided no information at all... That quote was ALL what you provided, do you realize how unreasonable your request is?
Are you purposely leaving the details out for anticipation or a surprise post later on? Want someone to guess your problem?
Like, did you flash a custom ROM? It might be because you flashed a custom ROM on a stock bootloader.
Did you flash TWRP maybe? It's a known issue in old TWRP versions flash the newest one and you're good to go.
Explain in detail what you did and post the necessary information. Like ROM version, wether you unlocked your bootloader, what is your rollback protection index and what did you flash on your phone. Your phone model might also help so someone can get you a stock ROM.

My problem is simple when I restart my phone it boot's automatically to recovery mod by it's own
I did not flast any TWRP or custom rom what so ever I don't have root access too all I did is some miui 12 update

No your problem isn't simple.
Based on the information you provided. What just happened is a soft brick and it can happen due to various reasons one of which is when updating android's firmware.
The solution is backing up everything then installing a new ROM. Beware the rollback index of your phone as it may cause hard brick.
I highly recommend going to your nearest service center and asking them nicely to unbrick your phone with no memory loss since you don't sound like you speak the mumbo jumbo language. (Basically a noob. No offense)
Again you provided little to no information at all, therefore i can only do as much.
