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?

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..

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.. :/

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

1 - Backup my app list (I've found Ultimate Backup Pro is very nice)
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

To do a nandroid advanced restore of data from a gb rom to a ics rom? Currently on calks ics fd24 and i have a nandroid of blazer rom. Would doing an advanced restore of data be ok or do you think it might mess something up?
Sent from my SPH-D710 using xda premium
I'd use sfhubs autoroot EL26+StockCWM. Safest bet for sure.
Im not trying to go back to gb, i want to restore my data from a gb rom to the ics rom im on now.
Sent from my SPH-D710 using xda premium
Oh I wouldn't do that yet. But, you can try it an let us all know. For maximum safety I've just been using Odin to flash then going back to the stock EL26+CWM to then flash to ICS builds. And then I have to reinstall all my apps and do the configuration of everthing again - real pain in the anus. Main reason I haven't been flashing as much. I have kept coming back to my Blazer Rom. After messing with ICS I'll do the above (Oding stock EL26, add stock CWM - both from sfhub) then restore my last nandroid. It gets me back to completely working phone. I'm hoping to get some answers to using the 'preserve data' option to update/upgrade so I can save a crap load of time and effort.
Ill try and see what happens. Also, i thought the ics kernels were only giving problems for flashing roms? Whenever im on a ics rom and i want to go back to blazer, i just wipe and restore, no issues.

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
Sent from my SGH-T989 using Tapatalk 2
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.

A friend created a nandroid and Titanium backup for me, and my phone is rooted. I'm currently on ICS and I want to go back to GB, Do I have to Restore Epic 4G Touch With Pre-Rooted Stock Gingerbread Firmware — EL29? or can I just use nandroid recovery since it's like a full system image right?
So confused. Want to go back to old GB without losing apps or settings. Please help?
You can restore the nandroid from a safe recovery like EL26.

Yes that helps. If you don't like ICS (FF18) ODIN back to EL29 (Gingerbread). thats the safest way or to keep what you had under your backup; ODIN Direct boot kernel here: http://forum.xda-developers.com/showthread.php?t=1662295 its under the GB touchwiz based kernels. Flash that kernel, it will only boot to CWM and then restore your backup. But to let you know, there are better custom ICS ROMs that are very smooth and stable. Just make sure you use the safe kernel/recovery like this: http://forum.xda-developers.com/showthread.php?t=1767421 Then you can safely wipe and flash any ICS ROMs you choose.

I downloaded this: SPH-D710.EL29_CL852097_ROOTED-oc-sfx
but will it delete my apps, settings, msgs, etc?
It seems like it will factory restore and wipe everything>
Is there a way to just use the backup and reset it to then? If so can you please dumb down instructions and what it will do? I really really appreciate any help. I'm sure that once I go through it, it will make more sense but at this time, I'm overwhelmed by all the different setups and instructions from different places.
All I want is to restore a backup I have with GB. What is the easiest way to do that without losing info?

Ok get titanium back or a backup app. Then back up all your apps, just apps not system settings. then with titanium back up you can make a flashable zip. odin back to EL29 + CWM. let it boot up. Then power off, reboot into recovery. Flash Titanium backup Zip. Reboot. the titanium backup app will be on your phone. then restore apps only, not apps with data as ICS is very different. All done

I would love to LOVE ICS but the only thing I want my SGII to do without apps or widgets that I have to turn on and off to use:
Control orientation: I sometimes read in bed and it irks me that I have to use an app called Autorotate Switch to stop it from switching views, it does work but sometimes cuts off the top of a chapter. I can also hear it "fighting" with the system to prevent it from rotating based on the angle I'm holding it.
Control Brightness: The lowest setting isn't dim enough and I have to use a screen filter. Now with ICS it autoadjusts the lighting even when the toggle is off the setting to adjust brightness automatically! I hate this new feature.
Social Hub: I actually like this since it integrates msg and email and fb together. The new ICS lets me easily delete without confirmation, something that's good, but it broke update syncing contacts and the emails are huge and it's a big mess with scrolling and spacing.
Camera: All I want is to assign a shutter button to a camera
Phone: I want to call out in speaker automatically. I had set this up in WebOs and it was awesome especially for driving.
I seriously would consider trying out other ROMs if they can help me do this...

That is the GB direct boot kernel that I linked it the previous reply. Flash that kernel/recovery in ODIN or mobile ODIN. Then restore back up in backup/restore option in CWM recovery.

Okay so my sister updated her epic a few days ago, and has been having nonstop problems with the ICS build FF18 there are just so many bugs in this and wondering if there is anything she can do without wiping her data on the phone.
She has two options. After ROOTING and flashing a custom recovery, she can either:
1. Backup all the data she wants: apps, sms, system settings, home screen layout and call log.She can use ROM Toolbox, My Backup Root or Titanium Backup. Those are the best. I personally recommend ROM Toolbox, but My Backup Root can backup sms and call logs.
After that she can flash any ROM she wants and then restore the data of all the apps.
2. She can try to format system only and then flash any ROM she wants. This is the easiest way but it is very risky to do it.
The first method is the most recommended. It is always recommended to flash a clean install.
Hope this helps. You can find all the links you want for Rooting and Flashing in the Android Development section.
If you need anything else, let us know...

About the only option you would have then is using Kies to backup, wipe the phone with a factory reset and restore through Kies.
If you have been reading through the threads, then you should know that the brick bug is still a major concern with the latest ota.
But you really don't have any other option if you're not going to root.

I don't blame her. It's no longer a great or even good phone for the majority of people. Even with custom roms and customizations I get about half the performance. They should have never released this update to the masses.

It is the apps that are on there. She has to start from a clean slate. Get Go BackUp, backup just contacts, sms, mms, and call log. Factory Reset. Then reinstall the the apps she wants from the Play Store. This worked for me.
you need update the device to stock FH13.. maybe fixed your issue about battery drain...
Running FH13 with 2 hours on screen time and 60% battery left. I started at about 90% after flashing the update patch from FF18 to FH13.
