[Q] Rooted my phone, now how do I flash a custom ROM/kernel? - Verizon Samsung Galaxy S III

Finally was able to succesfully root my phone last night, and now I am wondering how to actually flash a custom ROM. I figured I'd start with Cyanogen since its the most popular and seems like a good starting point. So, I have a few questions.
1. How do I install the custom ROM? (Cyanogen in this case) Also, is this process the same regardless of what android version I have? (I'm currently on the stock 4.1.1 OTA)
2. Should I install a custom kernel? If so, is it the same process? Also, is my data wiped just the same as with flashing a custom ROM?
3. If I make a backup with Titanium Backup, will I simply be able to access/redownload my app data it if I redownload Titanium after I flash the ROM?
Any and all help is appreciated!

I'm sure everyone has their own advice, but I would say first thing you'll need is ROM Manager
Download the ROM you want and place it on your sdcard. Use Titanium Backup to backup your applications, and then restart your phone in Recovery Mode. When in recovery mode, make a backup by going to "Backup and Restore" > backup. Then do a factory reset and wipe your cache. Install the new rom and enjoy the addiction

Also...be careful making sure that any kernel flashed is compatible with the ROM you are flashing. If not you can brick your phone.

1. IMHO, you should extract necessary settings or data and restore to your new rom. You can use AppExtractor
2. No need to delete everything before restoring
3. Your choice. There is touch version out there. Try and love it

Thanks for your reply i really appreciate it.
i was saying that if i wana go back to my stock rom (original rom) wich is not rooted can i restore it using CW?
if i flash back to my stock nandroid backup using CW my phone will not be rooted and it will restore the default samsung rom?
its just my theory though i haven't tried it yet i`m asking question like this for my future reference
Well...
Yes your device wont be rooted and will return to the stock rom.
Since the nandroid backup copies the whole partition. just like Norton Ghost does on the pc, so your phone will just go back to its exact status it was at that time.
You wont need to wipe user data/factory reset, because of the data partition being restored by CW.
Well you are asking for a recovery. How did you make a nan backup if you have no recovery?
Or you used the stock one? if you used the stock one, aren't you able to use it to restore?
Or do you want a new more powerful recovery?
As in the previous post they mentioned, use the one you like, with the most options

Issue with CM9 ROM on Motorola Defy

Few months back i flashed CM9 ROM by Elypson3 on my Moto Defy.Presently there is a new version of that ROM which i downloaded and flashed.I have Nandroid Backup of the previous ROM.After flashing the updated version of that ROM i am getting ROOT problems using Superuser.When i use the ALLOW all app the root permissions in Superuser,the apps does not allow the root(Tested onany apps including Titanium Backup Pro),but when i use the PROMT option in Superuser settings,the root works on all apps when i tap ALLOW button on promt.
Is there any problem in ROM or i have to ROOT my phone again?Also if anyone can post some simple steps to flash ROM freshly(like a very new ROM and not including a single bit of data from previous versions,like wiping data etc.) would be really helpful.
Go into superuser app & check for update. You can try to unroot, reboot, & reroot. Play around how you like, since you (smartly) made a backup.

I don't know what SFB is, but I'm guessing you need it for the ROM to work on your phone? In that case, ROM first.
Nandroid backs up your whole phone's internal memory, so restoring will take you back to whatever state your phone was in when you made the backup. The contents of your SD card are not included in the backup.

You can install ROM Manager from PlayStore and use Clockworkmod to backup your ROM. Or you could also backup your rom by entering your device's recovery. You can trigger it by pressing a specific combination (Volume Up, Volume Down or both alternatively - depends on your device) of buttons while the device is switching on.
You can find elaborate explanations here: http://forum.xda-developers.com/showthread.php?t=1587607
Hope I helped.
In a nutshell, what you are looking for is called a making nandroid backup. There are many programs which can accomplish this. My favorite is 4EXT recovery, which you can download from the play store. It does require you have root to install 4EXT! After you have a program such as 4EXT or ClockworkMod which can make nandroid backups, then you can save them and restore them in the future. This is how you can return your phone to the exact way it was when you make the backup.
thank you for advising me 4EXT recovery and ROM Manager.
What about titanium backup?
i made a backup(i hope so) by Titanium backup, by selecting the option "Backup all user apps and system data".
my questions are:
1) is that enough for back up?
2) how can i restore it after installing a new rom?
3) in between the process of installing if my phone become dead or blank how it will possible to access titanium backup?
oh its so much complicated. plz any developer help me.
thanks in advance.
installed ROM Manager Premium v5.0.2.7
if select
1) "Flash CWM Recovery"
asks to confirm ph model-> select iris 454 -> says "it does not have an official supported CWM yet. Have u installed a cwm based recovery manually?" -> if i select "yes," 2 option comes for confirm version cmw 2.x and cmw 3.x -> after selecting one of those nothing happen.
2) Backup current ROM
displays "new backup name..." -> if i click OK the system reboot. -> in reboot process an android symbol comes and suddenly it lay down like a wounded man. -> system hangs ->only removing battery makes it solve.
Yes, that's enough backup. You have backed up all your system data and applications. So you can restore your phone's last known working state.
After installing a new ROM, you can download Titanium Backup from PlayStore and use it to restore everything.
Note: Some ROM's don't have PlayStore available in their package in which case you'd have to download the gapps package separately and flash it too while flashing the ROM.
You cannot use Titanium Backup if your phone doesn't come alive. You'd have to restore the stock ROM or flash some other known-to-be-working ROM. You can then restore your stuff.

I've never used a nandroid backup, I usually do a backup with go backup (sms,phone log,wifi passwords and apps with preferences) which is an easy and intuitive app. If something fails i have a tested rom which i flash before do anything else.
Why it's better to do a nandroid backup and not just this??

thnx dear.
titanium backup is enough for me.
but now what about" if your phone doesn't come alive"? how should i restore the stock ROM if it is unavailable?
can i make stock rom or make a back up of stock rom? how?
Sewrizer said:
this means that your device is not supported by CWM recovery so there is not much to do, unless your stock recovery can perform the same tasks as CWM. for instance sgs2 recovery mode only allows you to install zip and to wipe cache and factory reset.
On the other hand there is a risky method you may try but i am not sure whether it would work. Install odin on your PC or mobile odin on your device and look for a kernel which has CWM recovery in it. THIS IS A RISKY OPERATION SO THINK BEFORE YOU DO THIS. I'm saying this because i bricked my sgs2 and the only way i could make it work was to restore, but again, you need CWM to restore. good luck.
hit thanks if i helped or reply/ send me a PM if you need further details.

You can find the entire procedure for backing up your Stock ROM here: http://androidadvices.com/backup-stock-rom-clockworkmod-rom-manager/
In order to restore Stock ROM, turn off your phone, boot your phone into recovery and use the restore option in the screen you see.

Can you put your phone in recovery mode? I if so, take a picture of it and post it in a reply.

[Q] Flashing a new Rom help

If i clean flash a new Rom but restore the data part from a backup i did earlier from another rom from recovery will it work? Im using TWRP recovery.
ive always had mixed results on this. if youre going from a TW ROM to an AOSP or AOKP rom, likely not. If you use TiB and backup your apps and their respective data, and restore them via the same method, that 99.9999% of the time works

[Q] How to use stock ROMs to upgrade PRL, for rooted CM 10.2 phone?

Hi,
I'm running CM 10.2, and using TWRP 2.7.1.2 Recovery.
I think that when I was "cleaning" my phone prior to installing ROMs, I was a little too thorough, since based upon my poor 3G/4G performance/coverage, I guess that my PRL list is pretty minimal.
I gather that the procedure to fix this is roughly:
Make a Nandroid backup from Recovery
install a stock ROM
update to latest PRL
Restore the Nandroid backup
But I don't understand some of the fine details. In particular:
When preparing the Nandroid backup, what options does one use?
What sort of "wipe" if any, does one perform at this point prior to installing the stock ROM
HOW does one install the stock ROM image asanti_c_sprint-user-4.1.2-9.8.2Q-122_XT897_FFW-5-6-release-keys-cid9.xml.zip ?! It looks a little different than custom ROMs
After updating the PRL, what sort of "wipe" should I perform prior to recovering from my Nandroid backup? I'd like to be thorough, but not so thorough that I wipe out the PRL update. Where does that PRL list reside?
Does the Nandroid backup include the ROM images which I flashed? (CM 10.2 and the corresponding GAPPS) If not, then in what order does one flash ROM images and recover my Nandroid backup?
TIA ...
1. Doesn't matter, whatever you feel you need to restore. At a minimum backup system. Backup data if you want your data saved...
2. None, if you use RSD Lite to reinstall stock it will wipe ALL. Everything will be back to stock (including recovery).
3. RSD Lite.
4. PRL List should not be wipe-able from recovery, AFAIK. Factory reset should be fine.
5. The backup will include whatever was currently running on your phone - CM, gapps, any installed applications, etc. Simply restore your backup, no order of operations here. Of course you'll need to reflash TWRP in order to restore your backup (again, flashing with RSD Lite resets the ENTIRE phone, including custom recovery).
If you had taken a backup of the stock setup, you could skip the whole RSD Lite crap and just restore your stock setup, download the PRL, and restore your CM setup. For future reference, step #1 after getting custom recovery is always always ALWAYS take a backup of your working stock setup before making any other changes.
Thanks for your detailed response. As a Mac user, I believe that RSD Lite isn't a viable option for me. I do have another Motorola Photon Q phone with the stock ICS image, but don't know whether that is helpful in this case.
I guess that I need a strategy using adb, fastboot and TWRP. Thanks ...

The stock backup from that other Q would work. Just do a factory wipe and restore 'system' only from that other Q.
