How can you save your current ROM?

hello is there away to do the title of this thread?
I have a unbranded ROM but it's loaded with my operators Data settings, and I'll be loathed to type them in if I decide to return to the stock ROM, so is there a way to save your current ROM incase it goes wrong, or your flash and decide to go back?
TIA Luke.

Nandroid backup - which you will certainly be doing before flashing anything new. Won't you?
Thinks - you are rooted aren't you?

Does anyone know if you can back up your ROM without root, before gaining root access?

Simple answer is no, it can't be done. You need root to backup your rom.

Actually, you don't need root to do a nandroid backup. Just a custom recovery.

I am new to this, coming from iphone. I just love all the features and customizations availalbe.
Rooting on my galaxys4 was easy. thanks all
Thanks for this info too. just what i was looking for.
:good:

If you have rooted and installed any decent backup software they can backup the entire rom and all settings.
Then even if you mess up your phone and boot loop it, as long as you can get into recovery you can restore everything.
So it serves multiple purposes, I prefer this method to rom manager and titanium backup.

[Q] How to tell which ROM I've flashed?

I can see Android v4.1.1 on System, About, but I totally forget what ROM I flashed. One of the more popular ones, last October or so. How do I tell what is on the phone?
Thanks, and sorry for the dumb question...

Don't you have the rom zip saved? It should say what rom it is. Although you should know what you are flashing.

Might I interject here? If the only reason you want to go back to stock recovery is to get the OTA updates, I personally don't think you need to. Typically, Freeza has the most up-to-date Stock, Rooted Rom over in his thread. In my case, he usually has it well before I get the OTA notification from Sprint. If you think his thread is daunting to look at, you really only want to flash one of the following (I always remove direct links to the Roms out of respect for the dev's):

The MC3 Rom is a leak of a new OTA that might come out soon (or it'll be incorporated in a future OTA). The MB1 Rom is the most current, stock Rom. All you have to do is flash it and you're updated. If you need help with how to flash it, you can look to my post over here. Since you're going from 4.1.1 to 4.1.2, I'd recommend a "clean install" (step 5 in my instructions) just to minimize the chance of Force Closes, but you should be good if you want to do a "dirty flash" (only wipe cache and dalvik cache). If you dirty-flash, though, any and all troubleshooting will boil down to doing a clean install and seeing if the problem persists.
Also, CNexus has written up a really good OTA Guide to help you understand the whole OTA thing more and to recognize your options. You can check out his post over here.
Hope this helps!
Edit: It might also be good to update your Recovery before proceeding. Depending on how old your CWM is, it might be best to get an updated one (with hopefully fewer bugs). Thankfully, Naddict has created updates that are flashable from the Recovery itself. All you have to do is download the one you want (I'm using TWRP 2.5.0.0, but CWM is fine, too) and flash it in your custom Recovery, then reboot into recovery again.

topherk, thanks!
I took your advice and upgraded my ClockworkMod. (I also installed TWRP, which I think overwrote it, but that's another story).
I'm going to go over your post in more detail (hopefully) this weekend.
I tried flashing some different ROMs to see what they were like. I was not impressed, so I went back to stock.
Can you tell me something? If I use TWRP to back up everything, I still need to install GAPPS, right? Then I need to do something with GAPPS and Platinum Backup before I wipe/re-install to keep all/most of my programs/settings, right? Then run GAPPS again after I flash the new ROM?

Yeah, you can only have one recovery installed at once. I use TWRP, others use CWM. In my opinion, it shouldn't matter too much. They're both good and as far as I'm aware, the newest of each are relatively bug-free. The only thing is once you have backups for one, you can't restore them with the other. This isn't that big of a deal, but just an FYI.

I'll break your questions here:
As far as I'm aware, all TouchWiz Roms include GAPPS in them by default. Of the flip side, no AOSP Roms will include them. This is because Google has asked dev's to not include them (in a Rom) unless specifically approved by Google. Samsung has gotten that approval for their TW framework, so any Rom based on TW can (and do) include GAPPS. If you're in doubt and the Rom doesn't say, first re-read the thread, as it's a common question. Then you can just flash the Rom without GAPPS and load up your phone. If GAPPS is included, you'll have a play store. If not, then you can just reboot into recovery and install it. Easy as pie.
I believe you mean Titanium Backup (another precious metal). Using TiBk, I actually have an automatic restore done every morning at 3am. Then if I decide to flash a new Rom, I always have an up-to-date backup of my apps. I never restore system apps, as that's just asking for trouble when switching Roms. I always back up my messages and phone log, but nothing that's red in TiBk. And for most apps, you don't have to restore data (only the app). I only restore data for games and apps like Hulu so I don't have to log in again.
Hoep this helps!

Yeah stock based roms will include GAPPS, AOSP roms cant because they arent officially licensed to distribute them...
As for the original question, I think I have it figured out. If you go to /system/build.prop and open that file, the great majority of devs will modify the relevant lines to the name of their custom roms. On cm roms theres a line called "cm.version=", which devs will usually modify that on a CM rom
The name is in there somewhere...could be changed on a couple lines, or on ALL the relevant lines, but it will be changed most of the time
Hope this helps

Is there a way to just directly upgrade Jellybean from 4.1.1 to 4.1.2 without having to re-install (via Gapps?) all of my applications, etc.?
I thought I read that I could unroot, do the OTA upgrade, then root again? I'm reading the OTA guide by CNexus, and 'freezing' the update app seems like a good option, but that just keeps the nag screen away.

All you need to do is follow the guide. You can download the MB1 firmware from freezas thread, and then flash an updated version of your rom. If you are on stock rooted, then you can flash one of freezas plain stock rooted roms over what you have (i would recommend a backup first though)

Just a small correction Gapps strictly refers to Google made apps (maps, play store, books, etc) you usually only flash these when working with AOSP roms. You sound like your talking about Touchwiz roms and thus your not loading all your apps through gapps, because Gapps are already included with Touchwiz roms. What you are referring to is reloading all your apps through Google Play Store and using the Google restore feature.

Yes! I'm talking about:
1) Backing up everything on my Galaxy S3
2) Installing other ROMs (sometimes stock, sometimes AOSP)
(side question: "stock" = "TouchWiz"???)
3) Magically re-installing *all* of my apps in the new ROM by clicking a single button
To do that, I'll need to use the "Google restore" feature?

You don't have to hit ok for each app when you use google restore the correct way. It automatically reloads your apps on your device. TB is a great also but never restore data it is the root of most issues caused when people use it.

Android laying down with red triangle after OTA update

First of all I would like to apologize for posting this because this probably happens a lot, but I couldn't find any forums to fix this, so I would be very grateful if someone could help me or send me a link to another forum with the same problem and solutions.
So I just did an OTA update on a rooted Samsung Galaxy SIII SPH-L710 phone and while doing the update it said that root access might be lost, attempt to fix? and so I pressed yes..so now and it turns on but will never get past the Samsung logo right before it gets to the homepage/apps or whatever. I have gone into recovery and data reset like 5 times already to no avail, and when I go into recovery..there are only like 6 options most are just apply update, there are no restore options. I had CWM installed but that's not showing up anymore. Yes I know I'm an idiot for trying to update on a rooted phone, but I would really appreciate any help that you guys can offer!

Ok, at this point, the thing I'd have you do is to flash a stock rooted Rom through Odin (while in download mode). The files are found in Sextape's thread over in their forums (warning, external link). Since you already wiped your user data and rooted, you should flash the "Restore" Version: SPH-L710_MD4_1130792_Rooted_Restore. They have directions on their page, so it should be nice.
Once you have root, you can use Goo Manager or Rom Toolbox to get a custom recovery back.

Thank you!! I will try this out and get back to you on whether it works or not.

And another note
Just to add something: In the future, please do not accept any OTA updates. If you're running a custom recovery or have frozen any stock apps, the OTA will fail (sometimes it'll get part of the way through, like yours did).
The best way to keep your phone up-to-date is to just flash the latest stock rooted rom when it comes out. Freeza typically has the latest stock rooted rom over in his thread, and for the most part, gets his Rom updated way before I ever get the OTA. You'll want to get the DeOdex version and if you're coming from a stock rooted Rom, you can do a "dirty flash" (only wipe cache and dalvik cache), no need to lose your user data.
Again, if you're running a custom recovery (CWM or TWRP) you're asking for trouble if you try an OTA update.

Sorry, quick question. Do you know if I should still be rooted after doing this? I see superuser still installed

yea you should be rooted if you used the rom that topherk referenced

1 click root for lollipop 5.0 that would be awesome

i mean custom roms are great but i have to many data stored and too much modifications in the apps which i dont want to wipe factory reset
i remember in 4.3 it was with twowel or something similar i dont remember
i just did the regular LG UPDATE to 5.0

I'm confused, is this a question? Because this is posted in the Q & A section. Also, there is absolutely no reason at this point in time to make a one click root for Lollipop when there is an effective root method for stock. If you want Lollipop that bad, you should rollback to stock and Stumproot then Bump your G3 and flash a pre-rooted official Lollipop stock build or just flash the updated SuperSU binary from within TWRP. What we have works great and took a long time and a lot of work to develop, no need to make it difficult for the wonderful devs who did this for us.

[Solved] Need help with installing Cyanogenmod (Without a PC if possible)

Hi all, new to all of this. Please keep this in mind as you read this thread.
Well first of all I have been reading about Cyanogenmod and how it helps saves battery. I also wanted to use cputuner to overclock my phone a little. I have in the past rooted this phone and installed cputuner not knowing that it could damage your phone if you didn't have a custom kernel that supported overclocking. After I found that out I uninstalled it and unrooted in fear of damage to my phone. Anyways I have a few questions and was looking knowledge, resources, and help about a few things.
Questions:
Is installing a custom rom and things needed to install a custom rom possible with a PC?
Can I safely reroot my device since I unrooted through #SU?
What do I need to do besides reroot my device in order to install a custom rom? (Cyanogenmod)
Thanks in advance!
Other INFO:
My device is a Samsung Galaxy S3 I-747
Firmware 4.4.2 KitKat
Device was rooted before using towelroot but I unrooted using #SU.
.

Ok. To install cm with no computer use, I'd say the easiest way would be to get root again with towelroot. Then install flashify from the play store. use flashify to install a custom recovery. I prefer TWRP.
Next download cm rom and Gapps. Follow the installation instructions for the rom. Generally that's boot into recovery, wipe dalvik, cache, system, and data, flash rom, flash Gapps, then reboot. You can do this from the internal SD, it won't erase that when you wipe. However, an external SD can be really handy for getting out of a jam.
If you haven't done it, a little research on the forums here about backing up your efs might be in order before flashing roms. Hope you never need it, but it could make life easier someday.
Read, read, read the forum here. This was just a real brief overview. If you don't quite understand any part, it should at least help you with what to search to learn what you need to know.

Thanks friend will look into it a little more. So is there a major risk of getting bricked or are chances slim? Also do you have any links to the Cyanogenmod version I'm looking for? I would like it to be 4.4.2, not 5.X.X. And I also need the appropriate gapps file. If you don't know I still thank you for the info friend!

Chances of bricking should be slim as long as you follow the instructions closely.
CyanogenMod 11 is based on Android 4.4.X, Kitkat. Nightlies can be found here or here.
Snapshot releases, sometimes called monthlies, can be found here.
There are options regarding Google Apps( GAPPS ) the choices from CM are here.
Some prefer the GAPPS packages provided by Paranoid Android, look here.

Thanks so much! Have been researching like crazy and odds seem pretty good. Problem is I've hit a ditch headfirst. I can't reboot using towering because I updated my kernel sometime through the period when my phone was unrooted (idk when or how this was done.) The date is apast june the 3rd and i read it won't work apast that date. Is there a workaround for this? I have no PC so I would like a non-PC method if possible. I just wanted to say I have tried all the modstrings for toweroot and still nothing.

The June 3rd date probably only counts if you took all of the OTA updates, okay rechecked your OP and I see that you are on NE4. I recall that either the NE4 or the NJ1 update patched the kernel to block TowelRoot. I take it when you say Firmware 4.4.2 KitKat you mean baseband, modem, and Samsung stock rom.
With SuperSu you can re-root using it, assuming you unrooted but did not remove the app. I don't know if the same applies to th SU app that comes with CWM. You could try. If you did go back to stock rom and properly formated you may no longer have su on your phone.
Yes, if you have a custom recovery on your phone you should be able to re-root without a PC. Search for the zip version of SuperSu, put it on an external sdcard, and flash it through the recovery. Without a custom recovery I'm not sure of other options not requiring root that do not involve a PC (Windows or Linux) or a Mac. Apps like Flashify require root, so will not work for you at the moment.

Thanks for the info, sadly I did uninstall #SU. Here is a ss of my modem info and such. I think it pretty much confirms I have the NJ1 version but I need you to confirm that.

I'm stuck.
You can install a custom recovery without having root, if you have a PC. You would use either Odin, Heimdall, or maybe adb.
You can install a custom recovery without a PC if you have root. You would use an app Like Flashify, Rom Manager, or Goo Manager (if it still exists).
You can flash a rom without a PC if you have a custom recovery, root is not needed.
Some roms, usually stock, can be flashed without a custom recovery if you have a PC.
I don't know the solution until you have access to a PC. I could see it being possible using a live USB with persistence of a Linux distribution, but you still have need for a PC. It's been a while since I created a live USB. The method I used required a small installation on the PC. so I don't see this as an immediate solution for you.

Oh sorry. I don't think towelroot works once you're on nj1, unless it has been updated.
If you get access to a PC, rooting is still fairly easy. You can use download mode and odin or heimdall to flash a custom recovery (be sure to uncheck reboot if using odin, or be really ready to pull battery). Don't let your phone reboot normally, you'll have to pull battery once odin is done.
Reboot to custom recovery, then flash supersu and you'll be rooted again, and set up to do whatever you want with your phone.

Thanks all for your help. I have decided I'm gonna give C-F Root a try as it seems very easy, then use Flashify to get CWM. Correct me if I'm wrong but there's no boot loader for my model type right? Couldn't seem to find anything on the subject except the Verizon variant. I'm gonna still need help deciding which gapps to flash as I'm gonna flash the latest Cyanogenmod monthly build. Is there anything else to be aware of when using a new Rom?

excuse for butting in .... but if you dont know your bootloader/modem info. here is an app called 'samsung info' that should tell you.
your question "...... but theres no bootloader for my phone model right?" kinda worried me. its important to know because they should match AND trying to downgrade can brick your device. on the plus side ; i've never seen a custom ROM include bootloader/modem in it.
again , just a thought and not trying to butt in.:good:

As mrrocketdog stated, the Samsung Info app will tell you your bootloader and modem. If what you previously stated is correct, they should both be NJ1. You can get the same info by issuing these commands in a terminal emulator on the phone:
Code:
getprop ro.bootloader
and
Code:
getprop | grep version.baseband

Appreciate the butting in! You may have just saved me from bricking my phone lol. Maybe I need to do a lot more research because that just lost me. So how do I tell that my phone is equipped with a boot loader? And if it is how do I disable it? I read that in order to flash a new Rom the boot loader must be disabled. (Correct me if I'm wrong) I'm no where near the point of flashing a new Rom (Cyanogenmod) but this is a great furniture reference to me.

every phone has a bootloader , two if i'm not mistaken. the one you're concerned with comes already unlocked on the good 'ol S3. (i bricked my first s3 trying to 'unlock' the bootloader). just find out bootloader/modem version (see posts above) to make sure they match (to avoid issues later) and just dont ever try to downgrade.

You have lifted a burden off my shoulders friend! Ever since I wanted to flash a custom Rom I've been worried if my phones bootloader was locked! I can now be at ease now that I know its unlocked. Will check upon that info about bootloader/modem.

Here is the info mrrocketdog

Is there a reason you can't use a PC to install a ROM?
I'm asking because I also do not know of a way to install a ROM without having root.
If you are able to root, you could try using the CM installer again.

Those are the latest versions of the bootloader and modem. You will be good for CM 12 or CM 11, and other custom ROMs based on CM. Older versions will work with them, but you probably need to edit the updater-script. (The older versions are not likely to include the NJ1 versions in the checks as they were not out when the ROMs were last updated.) NJ1 will also work with any of the ROMs based on the KitKat TouchWiz releases by Samsung.
As soon as you can find a PC to borrow you should be in business. Any chance of using one at a public library?

Appreciate all the help you gave me too friend, providing the links to cm and gapps, gonna borrow my friends laptop Sunday and try to root flash C-F Root through Odin. Thats the part that scares me but I should be good as people has confirmed it works for NJ1. Wish me luck friend. Would you recommend installing CM12? I personally like kit Kat and I know CM11 is based on that but is CM12 better? I guess its based on Lollipop
