[Q] firmware upgrade question - T-Mobile Samsung Galaxy S II SGH-T989

hi,
i've been on 2.3.6 for a while now, and i would like to try either cm10 or aokp.
do i need to do anything before flashing these roms, besides flashing v6+ cwm, and being rooted?

As long as you're rooted and have a custom recovery (CWM or my favorite, TWRP) you're good to go. You may want to get the app, Titanium Backup to backup all you apps and their data (do user apps only, system apps and system data don't transfer well across ROMs).

Rooted, rom question

I was hoping someone could help me get things straight in my head before I proceed any further. Currently I am running stock w/root 1.47. The first thing I did was get titanium backup (donate version) and backup my apps and system data. This is where I am at a loss.
I want to be running a lean, fast phone with wifi tethering. Here are my questions:
I installed ROM manager, can this be used to test out different roms without rebooting into my recovery?
Is there a list of apps I can remove? I can use titanium backup to remove them (also, should I remove, pause, or delete?) Specifically I don't want things like sprint nascar, sprint zone, etc.
Will the roms remove my useless apps, or do I need to do it manually? Specifically I was thinking of installing baked snack.
Thanks
ROM manager has an option inside the app to boot you into recovery. No way around trying a new Rom other than going into recovery, wiping, and flashing.
Go to the android chef forum and search 'apps safe to remove' and it should turn up a thread that keeps a list of apps you can use.
Most custom roms, including baked snack, remove bloat apps (mostly Sprint apps)
Awesome, one more thing. I am trying to figure out what to backup using titanium backup. On my stock rom, lets say I have all the apps downloaded that I want to use. Do I want to exclude everything RED on titanium backup and just backup the green programs? When I flash to a new rom and go to titanium backup, if I backed up EVERYTHING and restore it, wouldn't it put the bloatware back on my phone?

Rom updates

Hi all,
About to root and rom for the first time on any phone and I was wondering a few things.
First, after I install clockwork mod recovery, I can make a backup... Does this backup have the ability to restore all of my apps and data after I install a custom rom? Also, does it restore things like homescreen widgets, app settings etc as well?
Secondly, after I install the rom of my choice, how does updating it to a newer version work? Will updating to a newer version wipe my phone completely or is it like receiving a stock ota update in that it doesn't erase anything?

1) The backups in clockworkmod are of your entire phone. Without a 3rd party app such as titanium you won't be able to restore specific pieces of it. IMO clockworkmod backups are meant to be used to restore your entire phone if something goes wrong. Titanium has a feature where you can restore specific stuff from the backups, but I would recommend creating backups via titanium rather than relying on what was done in clockworkmod. Personally, I backup everything with titanium then do a backup in clockworkmod before I flash a rom. App settings will restore, widgets do but many times you'll have to add them again because they restore with placeholders for whatever reason.
2) Updating a rom is dependent on the specific rom and often the version. Some roms you can just flash over what you're running, sometimes an update will be significant enough to require a wipe. Even if a rom doesn't require a wipe, I'd advise at least doing a backup.

Installing CM10 on Galaxy S3...first timer

This is my first custom flash off stock. I have actually had some experience flashing due to accidently flashing from LH9 to LG1, which doesn't work. So I had to install TWRP, do a factory reset, root it, and install LH9 from there.
But I plan on trying out CM10 and I have a few question.
A) Can I just flash CM10 in ROM Manager since it is built in?
B) How can I keep my apps, app data, account data, folders,settings...etc? I have both CWM Pro and Titanium Backup Pro installed.
C) Is there anything that is worse in CM10 than Touchwiz?
D) If I don't like CM10, I can go into CWM ROM Manager and just restore my Backup, correct?
To be honest you need to flash it and give a shot and see what you think, everybody loves something different.
Download from the cm10 build from the link in the xda thread and also get the 10/12 gapps.
Boot to recovery and make a NANDROID BACKUP!
When you install, you will need to do a full wipe.(Wipe Data/Wipe Cache/Wipe Dalvik/Format System in that order to be safe
Flash the cm10 rom and the flash the 10/12 gapps.
Then Reboot!
And enjoy the goodness!
I love CM10 or AOKP much better than TW, just my opinion.
Hope this helps!:cyclops:

QnA bud. Good to see you're starting to flash tho.
I've tried many, many ROMs on my S3 but I keep going back to CM10. Even though it's not a stable release for my model it's still awesome
Couldn't I just use ROM Manager since CM10 in on there and wipe data and cache?
Isn't the CWM ROM Manager backup a Nandroid?
How could I keep my apps and most my data...etc?
I appreciate your help, but I was knew how to do it in that way
Use Titanium to backup all your apps & data, boot to CWM recovery take a backup and install CM10 then restore your apps from Titanium, should be that easy!
Yeah, perhaps you guys don't use it, but my question remains. I've backed up using ROM Manager and transferred that image to my PC for an external copy. Couldn't I just install CM10 using ROM Manger as it is supported? Isn't that backup a NANdroid?
Or is it just not preferable?
Thanks for any help guys/
Can someone please answer my questions?
rom manager simply boots into recovery for you and makes the backup itself, etc. however, if you want to do more (wipe /system, etc) you need to go into recovery manually and do it.

So basically I should can ROM Manager to upgrade CM10 or restore, but not flash new ROMS?

i'm confused by your wording, sorry. rom manager would be suitable to your needs. it can install a rom for you, but it will only wipe data/factory reset. it will not wipe /system or dalvik cache like so many installation instructions say to do. rom manager can backup your rom and restore your backup.
so yes, you can use it if you choose to, but learning to use cwm would probably be easier in the long run than needing to rely on an app.

How would I keep photo or music that are on my phone's memory? Aren't they in a SD parition?

they are either on the internal sd card or one that you inserted into your phone. you won't lose any data on those.

You should really do some reading over in the development section. They're full of information that can answer all these questions you have.

Tools

Need some help moving forward with rom installation. Have been reading and playingback guides and articles in the last few days on rooting and roms. Just rooted AT&T S3 I747 ver. 4.1.2 and have access to SU. Installed Revovery Tools from DsLNeXuS and Titanium Backup Pro. Made a backup with Recovery Tools and stopped.
I'm going back and forth between guides noticing some of them were written over a year ago. Have been using these guides below.

Questions. Are Recovery Tools and Titanium Backup Pro used for the same purpose? Is the toolkit below an alternative to both these tools, RT and TBP?

Do I need to run RUU flashing?
Thanks.
Thanks.
Recovery backups are for if something happens to your phone you can restore phone its original sate by choosing backup from recovery.
With Titanium Backup you can backup your applications and data. Tomorrow if you install a new ROM you can just restore applications along with data from Titanium Backup.
When you flash anew ROM you will loose all your current apps and Titanium Backup is used to restore them.
Thanks. Sounds like I don't need to have both recovery programs but Titanium Backup will do.
When backing up apps is it necessary to back up all the at&t apps?
I am still at a lost with RUU. Do I still need to Flash RUU?
thanks.

You use titanium backup for backing up apps and the associated data (logins, settings, game progress, etc). For installing custom ROM you need a custom recovery such as CWM or TWRP. Samsung stock firmware uses ODIN vice RUU.

So I'm hearing "restoring data from one rom to another can cause problems". This will be my first rom install. I've already backed up all apps and data. Do I have to pick and choose which apps I want to restore after flashing a new rom?
Thanks in advance.

It could cause problems. If it occurs, it is usually when switching from a Touchwiz ROM to an AOSP ROM and vice versa. If you are going from stock TW to a custom ROM based off stock (or AOSP to AOSP), you will likely have few to no issues. App compatibility with a new android version is another matter (I.e. ICS to JB 4.2). It could happen over changes in android versions but it is not likely and even less so over minor variations (4.2 to 4.3 for example).

Restoring "System" data from another ROM will usually give you problems.
Also, it might be a good idea to copy your EFS folder from the root of your phone, using a file explorer program, to your SD card or computer before you start flashing ROMs, as most people who later had data connection problems (lost their IMEI numbers) never got around to doing it.

Any file explorer program recommendations to copy EFS folder?
Are "custom ROM based off stock" and "Samsung based ROM" the same thing?
I am currently running AT&T Android Version 4.1.2, Baseband I747UCDMG2. Can you recommend a couple of known stable Samsung based ROMs?
On backing up apps and data. When preparing for the very fist ROM flash, does it make sense to not backup all the bloatware apps AT&T has in 4,1,2.?
Thanks in advance.

1. Root explorer is good. But it's a paid app.
2.Yes
3. S3Rx, Dandroid, Intergalactic, and Graviton are some excellent touchwiz ROMs.
4. Do not restore system apps!!

I currently have Recovery Tools, Titanium Backup and ROM Manager installed.
Do Recovery Tools ans ROM Manager do the pretty much the same thing? I see a lot of info for ROM manager. Will I be able to do everything by keeping only one(ROM Manager?)?
Is it better to always flash from external SD card instead of internal?
Slim Bean
Figured it out. Running Slim Bean 4.2.2.build.8-OFFICIAL. Don't think I can ever go back. Well worth contribution to developer.

rom flashing and data loss

asking for a friend who can't make the post currently on xda but he's looking to flash a rom over to his Samsung Galaxy Note 3 (T Mobile) which is already rooted. The question is would he be able to flash the rom over and then things such as Gapps ect and then restore from a Samsung kies backup? (kies essentially is a perfect backup for Samsung phones for those who aren't custom to it)
Or what method would work to not lose stuff after a rom flash? (texts/app settings ect)
Kies cannot be used with a custom ROM.
Use Titanium Backup to backup as many apps and data as possible.
Before flashing a new ROM, make sure to take a nandroid backup before flashing.
