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

I decided to flash back to stock because I was having some reboot issues. Everything went fine except that I noticed my internal (sdcard) memory was wiped after returning it to stock and re-locking the bootloader and all my backups were gone and music etc... Is this normal? Kinda crappy since we can't just pull a SDCARD to stop it.
You relocked your bootloader. This will cause a wipe all across the board. If you wipe via recovery, it does not wipe your sdcard.

Relocking the bootloader does not cause a wipe... but unlocking it does.
As well, flashing the data partition with the stock data image will wipe the /sdcard folder.

OP, you may want to seriously consider Titanium Backup if you are not already using it. Then setup a dropbox account, and sync your backups to dropbox. Makes things real easy to restore if you wipe everything. You could also keep a copy of your Titanium backups on your PC for quick retrieval as well.

Any way to do this unrooted and still locked? So that when I want to re-root and unlock I wont lose it all again?

Yes. Leave your boot loader unlocked. There is no reason to relock it

Apologies for thread hi-jack...
Gentleman, by leaving the boot loader unlocked will the eventually 4.0.3 OtA still push onto the phone?
I'm completely new to the android scene having come over from the iPhone 4.
- I unlocked bootloader (lost all data as expected)
- Rooted
- Used CMW to install the 8mb 4.0.2 update (GSM)
- Used titanium to back up for the future
- I've left the bootloader unlocked, so my question is - will i have to do the manual update for 4.0.3 as i did with 4.0.2 or will it push?
Thanks all

It will push automatically whether your bootloader is locker or unlocked. However, as with all updates, it may be faster to manually update it if someone who gets it early posts the update link.

Is CWM required to flash stock images, whether they be either the small update files or the full factory images?

I've been rooting for the past 4 years, so I'm not a COMPLETE idiot. But I have no idea how I did what I just did. (Well, I do, but I'm in denial
I've used exhange for work email for last year and a half. Over this past weekend, I couldn't get in to email, and kept getting a popup to encrypt. I figured I had to, to get to my email(and probably so). So, I did it. And then realized I couldn't get into Recovery. In full agitation mode, and while in recovery, I fruitlessly tried wiping, and just as fruitlessly, tried to get to my data to try and just flash a new ROM over it(couldn't do either, because of the encrypted data). SOMEHOW, I freaking managed to format system by the time I was done.
SO, in summation- I can get to recovery, can't restore a backup, can't get to my data, and can't get my phone to boot.
What the crap do I do now? From what I've read, it would appear I have to unroot and flash a stock/unrooted image, is that correct? Will I wipe out all data on the phone in the process? Can someone push me in the right direction for the easiest way to do it? (keeping in mind, can't get my frigging data, nor can I mount).
Oy Vey.
Many thanks in advance!
I think you should download a stock image from google at https://developers.google.com/android/nexus/images and just install it. I assume you can still get in fastboot mode. Of course you will lose your data, and I don't think you can omit flashing the userdata because I think you will wipe the encryption salt. I think someone with more expertise should answer this.

You could try flashing TWRP through fastboot. I think it has support for decryption. I'd look it up first though.

+1 on TWRP! Back from the dead. GREATLY APPRECIATED!
Now on to to this freaking pesky encryption. What a mistake.
At least now I can copy my data off the phone, then wipe/revert to stock to get rid of the encryption(I hope?) then re-root.
I rooted well before the Galaxy Nexus Toolkit came out. Assuming there's a one click(or multiple clicks ) for unrooting and rooting?

You could just flash the factory images, flash recovery through fast boot afterwards, and flash a superuser zip if you're gonna run stock rooted or just flash ROM of choice.

Hello all, weird problem. I've tried numerous times to wipe my phone to reinstall CNA 3.6.6. I'm running the latest CWM.
I boot into recovery and do a factory reset and wipe/data/cache/system. All the prompts show that the phone is being wiped etc... Then I reflash the ROM and Gapps. When I reboot its as if nothing happened. It seems like the Full wipe did nothing. Any ideas? Really perplexed!

Best to just flash back to stock. Format internal SD while you are at it just to be sure.
You still have GNex toolkit installed on your PC right? Download and flash the stock ROM, format internal memory and start from scratch.
Disregard this post.
Thanks. I'll give it a try.

This happened to me last night. Was on jbsourcery, wiped, flashed aokp and it wouldn't boot. Reflashed jbsourcery and it booted as if I never wiped it.

try twrp recovery. it could be an issue with cwm most likely. its a shame if you went through the process of flashing the factory image and reroot if its just an issue with that recovery.

I remember there is a computer program called android commander. You might be able to use that to get the info but tbh I really don't know. This is the issue about not having a removable sd card
Problem solved. I was able to adb pull what I needed and returned to stock. Phone is working now. Thanks.

I previously installed the 4.2.2 camera before the OTA was available and this prevented me from successfully using the OTA because the phone wasn't completely stock. After trying all of the "typical" fixes like going back to the stock camera and a bunch of other stuff (covered in my last thread), I was told the only option I had was a factory reset. I finally had a free day so I did a Titanium backup as well as a nandroid backup with TWRP, saved all of my pictures and such along with the backup files on a backup HD, then did a factory reset through the android settings menu. Once it rebooted, it was "reset" but the 4.2. camera remained. I tried the OTA update and of course it failed. So I rebooted into TWRP, wiped the caches and then did a factory reset within TWRP and once it rebooted, I had the same issue (it was reset but the 4.2 camera remained). All of my pictures and the Ti backup files remained on the phone throughout this whole process as well, not sure if that's normal or not.
What am I doing wrong? It seems like it's resetting all the phone data but keeping my old modified rom? Thanks.
That's exactly what factory reset does
Sent from my Galaxy Nexus using Tapatalk 2
OK, I'm not sure why I was previously told on here that was my only "fix" then if it doesn't modify what I am having issues with. So what is it I need to do in order to get a factory ROM with the factory camera that will accept the OTA? I thought there was a "factory" way that would do it quickly/easily without going through dozens of steps?

For the record, I did see the link in his sig and read through his "back to stock" tutorial before asking if there was a way that didn't require dozens of steps. I don't have much free time so I was trying to see if there were any "easy" ways.
Regardless, I got it completely reset stock 4.1.1 and rooted again. Thanks for the help there.
Is it better to use my Ti Backup to restore things BEFORE installing the 4.2.2 OTA or should I do the OTA and then restore with Titanium? Thanks.
