[Q] Using Ti Backup from GB to ICS? - T-Mobile Samsung Galaxy S II SGH-T989

Sorry noob here but it's my understanding that I can't back up my App data and upgrade to ICS from GB, Is that correct? Is their anyway of updating to ICS and keep app data? I'm rooted and running Juggernaut ROM.

I believe most user apps and data can be restored from GB to ICS, just don't restore any system app, and keep in mind that some apps and games may not be compatible with ics and that's going to make the restoring batch get stuck, just keep that on mind

Will it Brick or Soft brick my phone if i redo a batch and it's not compatible do you know?

If you restore system apps or their app data, then it is likely, but if restored user apps have compatibility issues then you'll mostly get force closes.

quick reference
I do suggest referencing this post which has so far the best route if you're going your route. I have been able to upgrade and keep all the data using the stock upgrade in Kies for two other phones (not mine) and they have not had any issues.
I went the odin flash route and just want to remind you to wipe all the system partitions (I used Darkside SuperWipe) then flash Radio then flash ROM
hope that saves you some time.

Thanks Guys!!

Yeah, just hit batch and restore missing apps w/data. You'll be fine.

Im not able to post in the dev side yet, still working on my first 10 posts. So.. a tiny history, I am comming from 2+ yrs experience with WebOS and pre- & pre2. I am very familiar with customizing with preware, using all the patches & OC kernels.
So, what I have noticed, although webOS & Droid are both Linux based, it seems that they are fairly different when it comes to customizing.
This is my issue, I have a galaxy S2 epic 4g touch (sprint). When I got it, it was on EG30 (2.3.4). I was able to root and flash LOS and didnt have any issues. When the 2.3.6 update was pushed out, I didnt have a chance to unroot, so I ended up having to wipe/restore back to 2.3.4, then I tried to reroot, I got the no wifi and bootloop. I wiped and resotred again, all was ok, and I tried to root manually with the e4gtauto method, that I found for the EK02 stock system. Well, all was perfect, until just ran a backup with titanium, not restore, but just a back up. Is that my problem? Having titanium installed when rooted? I have been trying to follow QBKing77's processes, but need to just have a confirmation on the best process to root EK02 SPH-D710 on 2.3.6
Thanks,

Titanium and root is not going to cause the issue you describe.
For some reason going from los to stock sometimes has wifi issues. I suggest you backup, then odin the eg30 factory restore in my sig
When that is done, do a ##786# reset from dialer and let the hamds free activation take place.
Verify wbether wifi works. If it does apply the ek02 ota update.
Then start restoring your data backup.
Thanks for the response. I have been able to get my phone updated to ek02 with out any issues. As of right now, it is a fresh install with the ota update ran to get to 2.3.6, I have all my apps/data restored. The only thing I want to do is root, install latest cwm, SU, and busybox. When I tried to manually root, it worked perfect, so it seemes, I didnt have any problems until the next morning. I was wondering too, do I need to be rooted already to do a nandroid backup?

Sent from my Samsung Galaxy S2 - Epic 4G Touch - SPH-D710 using XDA Premium
You need cwm to do a nandroid backup. Technically you do not need "root" to have cwm, but practically if you have cwm you'll probably have added root as well.
I guess I don't understand what "problem" you are seeing 1-day later. You said you got by the wifi problem. Any chance your problem is related to the restore? Are you restoring only user elements or system elements as well?
The wifi issue the ive seen I thought was a common problem with the latest update, but ive found that it is not connected to the bootloop problem. The wifi issue that ive seen is that it stops functioning until you restore back to stock. That is what I have done, reinstalled the stock ROM from sprint, updated to 2.3.6, then rooted. (currently not rooted) but every time ive tried, it seems to be unstable and I end up in a bootloop..
Sent from my Samsung Galaxy S2 - Epic 4G Touch - SPH-D710 using XDA Premium
What I want to do is root as stable as possible. I dont have to, but from my experience, the devices are much better when rooted with the added functionality that you have access to.
Question about nandroid backups, does that type of back up take a snapshot of how your device is at the time of backup? Does restoring a nandroid backup put your phone back to the exact state it was when backed up? Root and all with apps and settings?
I want to be able to create a backup where I dont need to manually fix all my apps & settings, or is that even possible too?
Thanks for the help..

If you've rooted using the Auto Root package, there is no chance that is causing your bootloop (nor your wifi problems). Other root methods which involve a new kernel might cause something like that, but not for the general case or many people would be complaining.

I didn't re-read the whole thread to see what root method you used, but that is one of the reasons the Auto Root package exists. A minimalist approach to rooting that uses your existing stock kernel/rom.

It dumps the images of your system/data/cache/kernel partitions. It will restore everything to just like it was, except for the modem, which isn't backed up.
Thanks again for the responses. So, if I am rooting with the autoroot tool, what can be causing my no wifi & bootloop issues? I have tried with a fresh restore (to stock 2.3.4) and then root, and I have also tried a rooted EK02 ROM, both become unstable after resetting..
Im kinda bummed that I cant figure this out.
After it being super simple to root/oc 2.3.4, im frustrated that it is so different now.. :/

Sent from my Samsung Galaxy S2 - Epic 4G Touch - SPH-D710 using XDA Premium
Different kernels and OC are potential culprits. With the bootloop, I would think my first suspect would be OC/undervolt/etc. Not all CPUs can OC to the same speed and be stable.
So you factory restore to EG30 then wifi is working and no bootloop? Let it sit like that for 2 days. Then install root using auto root. Again let it sit for 2 days. Then finally start adding your other stuff one by one until wifi and instability gets introduced.
I can guarantee you 100% that rooting using Auto Root is not causing your wifi and bootloop issues. I'm saying this because of analysis of the changes Auto Root makes. It is just adding 3 files, which are mostly DORMANT unless you use them.
Concentrating on root as the cause of your issues is a waste of time. You need to look at the other changes.
Awsome, thanks for the response again. Should I install acs recovery or cwm to do a nandroid backup? I want to make sure I can restore easier than having to redo everything everytime, or is that expected to need to do everytime I "play" with this type of customizing.

Both are fine. Nandroid should get you back to where you started as long as you aren't doing modem changes.
does that mean as long as I back up stock EK02 2.3.6 before root, or does that mean I should nandroid backup at EG30 2.3.4 before root?
Sent from my Samsung Galaxy S2 - Epic 4G Touch - SPH-D710 using XDA Premium
Assuming you want to end up at EK02, I would make the cwm/nandroid backup immediately after applying the EK02 OTA update on top of EG30, before adding your own items back.
Run it completely stock for a day or two (however long it too in the past for the wifi/bootloop problem to crop up) If it doesn't show up, then start adding your stuff back in a few at a time. Once it shows up, you'll be able to isolate which most recent change caused the issue.
Awesome, thats what I figured, but I just wanted to be sure, I'll chime back in after I start if I run into problems.
Just to clarify, I cannot back up when I have it all set up with my apps/settings to where if I get a bootloop or something I can just restore with apps/settings restored? or is installing apps manually the only way to get the device back to how you like it for day2day usage?

You can make multiple backups, one at each stage, and restore to that point. The only thing you can't restore is the modem (you can flash the modem by hand, just not from a nandroid backup), but assuming you can get a stock EK02 which doesn't have any issues, then it doesn't matter as you won't care to go back to EG30, so your nandroid backups of EK02 should serve you fine to figure out what is causing your issue.
right on, thanks sf, moving from webOS to android will be a breeze with all of the great devs and such to ask questions. i was fairly impressed on how the development community for webOS was so open and friendly, i am glad to see that it is the very same way over here too!

Hi SF, i wanted to clarify my steps before i run through them. So i am currently running stock EK02, unrooted with plenty of apps currently installed. (do i need to be rooted to install cwm and then run nandroid backup?)
I was thinking my process is as follows:
1 - Backup my app list (I've found Ultimate Backup Pro is very nice)
2 - Remove external SD card and flash back to stock (outta the box) EG30/2.3.4
3 - Update to EK02/2.3.6
4 - Remount SD card, install CWM5, run nandroid backup. Is ACS recovery better?
5 - Root, wait 1 day
6 - Install SuperUser & BusyBox
7 - Start restoring apps a few at a time
? Does it help to reboot after each install for any reason. Also, are apps that require root access the usual reason that cause the wifi/bootloop issues, or can any app free or paid cause the same problems?
Again, i totally appreciate the info you have explained already! oh, btw, Merry Christmas!
see ya

2 - Remove external SD card
3 - ODIN Flash EK02 Factory Restore
4 - Remount SD card
5 - Use Auto Root package - Choose Option A to Root (ie install su, busybox)
6 - Use Auto Root package - Choose Option C, then EK02+CWM
7 - Boot into CWM recovery, make nandroid backup
8 - Run it stock for .5-1 day to make sure everything works
9 - Restore a few apps at a time (making note of what you restored), reboot and run for a little while to verify wifi works and it doesn't get stuck on boot
10 - run like that for a little bit, then repeat 9&10 until all apps restored or culprit found

[Q] Issues with rooted T989

My wife has a rooted SSGSII with the stock rom. I have the same phone but have a custom rom. She has alot of weird issues like sometimes freezes when a call comes in, her time in the system bar is often incorrect. She uses Magic Locker and sometimes her time in Magic Locker doesn't match the system time or they may both be off. I wonder if anyone has had this kind of issue. We have replaced the SIM card already. She used Titanium Backup to bring back her apps from her old Droid after rooting. I don't have any of these problems at all but she has crazy issues like this. Any thought about what might be contributing to these issues?
I've never experienced this before, but I have had major issues with titanium backup to the point that I no longer use it. Have you tried reflashing without using titanium?

No. We didn't flash her device. We just used TB to restore some of her apps after she rooted it. TB website said it would be OK to use it with a Stock Rom.
Sent from my SGH-T989 using xda app-developers app
i would assume TB meant it would be okay if it was from the same device... its not best when you're restoring apps from a completely different phone. I you sure its completely stock? i would just go ahead and flash a custom rom.
Thanks for the help. Think I will flash a custom rom and see if that helps the issue.
Often times if you use TB to restore apps and previous app data, this will happen. Couple options. Try restoring just the app without the data, or use ODIN to flash a clean stock, then re-root and start over. A clean can resolve a lot of issues. I ODIN my phone at least once a month regardless.

And the reboots could be related to the battery.
You need to learn how to backup and restore data anyway.
Titanium is a good tool. You need to use something to backup the apps.
Do a nandroid full backup of your current setup anyway (and then a restore to test it) so you can always go back too.

Everything went smooth.
Now the problem is that the phone still reboots randomly, I have taken out me sd card, thinking there could be an error, which was causing it to reboot. No resolution.
I have swapped the battery (third party), and still the same issue.
I think I need to get back to sprint to have the phone swapped out.
Is there a one click to do that?
Do I have to reset the odin? counter? to swap it out at sprint?

[Q] looking to switch roms? currently running jellybomb

Im new all this rooting and rom stuff and yesterday morning i successfully rooted and inststalled the jellybomb 14.0.0 jelly bean rom thanks to qbking77's on point videos. so the question is... how can i switch which rom im running? i like the jellybeen roms and im looking to explore more to see which better suits my needs. ive heard of doing clean/dirtry instals or something of the sort but i want the best and safest way possible so i dont run into any bricking trouble. please help?
Ok, read up on how to flash a recovery
Download the rom of your choice and place it.on your sdcard. Once you do that you can install roms by booting into recovery and finding the zip for the rom you want to flash and selecting it through the "install zip from sdcard" option
Now a clean install is whenyou wipe all partitions, aka blocks of your phones memory, (details farther down) and then install the rom zip. This method minimizes the chances for problems to occur after installing
A clean flash involves:
Formatting system
Formatting / Clearing data (also known as a factory reset)
Wiping cache
Wiping / Clearing dalvik cache
Now a dirty flash is when you just flash the new rom zip over whatever you're currently rumning, without clearing anything. This method is only recommended when flashing an updated version of the same rom, and even then, the nature of some updates can require you to do a clean flash.
One more thing, DO NOT flash any roms, mods, or zips for the international version. That usa surefire way to brick your debice because the partitions are completely different.

Backup via CWM (RECOVERY) is mainly for restoring the same rom or going back to the rom you were running if experimenting, Now, can use apps such as Titanium backup to save all the other settings, apps and things. Once you flash your new rom, download it, open program and can restore your stuff that way. Personally, I'll wipe, start from scratch, sometimes i'll download an app i never use, and it just allows me to clear out the useless ones.. Happy flashing!

Yes as said above, a backup through recovery (also called a "nandroid" ) stores an EXACT image of the current state of your device. Meaning all data, all system files, all apps, radios, etc. Backing up through an app, like Titanium Backup, only backs up certain things like apps and app data
Basically, if you're trying any experimental stuff that may break your system (for example, flashing a new modem or testing to see if a certain kernel works), then a nandroid is the way to go because you can restore to an exact image of a state when everything was working
Yea I did that the 1st time and couldnt recover anything. Is there a certain way I should recover or maybe I did something wrong? Im not sure. Sorry if im sounding stupid but I cant return my phone if I screw it up so im tryin to be as safe as possible. Hopefully thats understandable

No no, its recovery
The recovery is basically something that allows you to install zips, it doesnt actually have much to do with recovering anything lol
But first do what was suggested right above me to check to see if you have a recovery installed
To get a more detailed description of what a recovery is and what it does, you can get over to xda-university and read through the "as user" section on recoveries

[Q] Upgrading data from 4.2 to 4.3

Using custom ROMs, CWM & TWIP, backup apps like Titanium and Reware MyBackup, etc. are not new to me. I've done my share of ROMs on various phones & tablets.
It's really easy to say wipe data for best results when upgrading to a new Android version or ROM. That's typically what I've done as recommended.
But, when a carrier like T-Mo finally pushes out their update, for example the MK2 to move to 4.3, the data gets upgraded automatically and reliably. Obviously no wiping of data.
I don't want the locked MK2 bootloader and KNOX. Other than that, I'm OK with mostly stock.
If I flash one of the MK2 modified stock ROMs on top of stock 4.2 (maybe just rooted), will it upgrade the data just as it would when you do a carrier upgrade? If necessary, I would also flash the latest KT kernel & modem, so Wi-Fi calling would work and the latest baseband would match. Again, as close as stock for now w/o locked bootloader & KNOX.
This would save me a lot of headache and hassles with having to use Titanium for apps & data. I can always also do a Nandroid to back up before an after this entire process.
Has anyone tried to upgrade to the latest modified stock MK2 ROM on top of a stock MDL ROM and keep their data?
If you flash the rom you have to use titanium but believe me it's 10 times better than doing the ota.. It's worth extra step.sit down watch TV and let titanium do its thing.

A little background... I've been a SW developer for 20 years. I want to understand how stuff works. I have no problem screwing around with my phone, Nandroid, wipe data, etc. and have already done so. My wife just wants a working phone and could care less. I want to upgrade her phone w/o locking her bootloader and w/o KNOX in case I want to use her phone later. She wants all here system and app data to remain identical, otherwise, I'll have to hear her *****ing & moaning until I fix it.
Technically, is there any difference between flashing a the modified 4.3 stock ROM w/o wiping data and doing a traditional carrier upgrade in how it handles the upgrade for any data partition? (ignoring bootloader & modem upgrades). Does the carrier upgrade do anything different after it formats and installs onto the system partition? I wouldn't think so. Please correct me if I'm wrong here.
Also, I think it can be sketchy restoring TB System Data from older OSes (4.2) onto newer OSes (4.3). I'm particularly referring to stuff like SMS/MMS/Call Logs/etc. Maybe I'm wrong here and a newer OS is always expected to be able to upgrade order system data if restored?
So, in order to retain all that stuff (for her phone), it would seem that simply flashing the modified 4.3. ROM onto a dirty 4.2 data partition would be exactly what the carriers do when they push the update form 4.2 to 4.3?
Here, go to this thread follow the directions in the OP carefully and your wife will be on the latest boot loader Knox free MK2. Once you've finished that then you can flash any type of 4.3 ROM or 4.4 and not have datadrops or any problems. Pretty much doing the 4.3 ota for the bootloader but Knox free.

Flashing roms without wiping is not always a great idea. If you do... atleast clear cache and dalvik cache. You won't lose your data but you may or may not have issues. YMMV. As far as transferring system data from different Android versions, that is a no no. Just backup your sms and what not using the various programs on the Play store, most of them do a good job. What I REALLY recommend is for you to make a Nandroid backup using Nandroid manager or through your recovery such as CWM or PhilZ. Once you have this backup safely stored on an EXTERNAL SD card or on your computer, you can experiment and flash away. I doubt you'll have problems since the upgrade is minor but just have your backup handy... it is critical in case you have problems after doing the dirty upgrade and to avoid getting your butt whooped by the wifey
