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..
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.. :/

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

The wife did an Ota upgrade to Gingerbread battery sucked, so I did a factory reset. It was working OK for a couple of weeks until yesterday. It freezes about 20 times a day. It's stock and it just started happening yesterday.
I'm thinking of just rooting it and flashing cleanGB.
Any chance this is a hardware problem and would be dangerous to flash at this point?

Try to pin point exactly what you was doing when this first happened. Such as what apps you've installed. Got this tip from a fellow XDA member. Might help! If it is an app causing this issue, then just un-install it.
Question...was your wife's Epic stock before you did the OTA?
I don't think it's a hardware issue. You should be ok if you reset the phone bringing it back to a good working state then root, flash ACS recovery or clock work, flash a clean GB Rom ei22 based, or a rom of your choice.
Also, try rooting and installing cwm. Do a full backup, then wipe the cache 3x. If this doesn't make stable, do a full titanium backup and flash cleangb. You can then restore missing apps and data. Careful not to do a full restore, cause you will get the bloat that is removed like ciq.
Sent by my CleanGB Epic using XDA App
To determine if it is hardware or software you can try either flashing a custom ROM and see if that helps or Odin back to EC05 and let it OTA again in case something didn't go right with the update.
Hi Guys, thanks for the relies.
Yes the phone was and still is completely stock.
My intention was to root and put cleanGB, but I didn't have enough time last night because I ran into problems with the usb not being recognized w/ my laptop.
I ended up trying to root the phone with QBking77 Youtube tutuorial for the EI22 based phones, but ran into a problem: http://www.youtube.com/watch?v=kwFRzzIqouE&feature=relmfu
It verified the file kernel-GB-3a.tar.md5 put failed to flash it. I ran out of time and didn't get a chance to use another cable.
I ended up just a stock factory wipe. It's not freezing anymore.
Running stock 2.3.6, T-Mobile, T989. Rooted via ODIN, CWM installed. Wasn't paying any damn attention and flashed a battery theme. Now my status bar FCs at startup.
Is there any way to recover from this, or would I be better off unrooting/returning to full stock and then rerooting, reinstalling, etc?
There may be a better answer, but I would just flash a new rom. There's so keep roms available if that's what you want

well, if you made one do a nandroid backup. should work if im not mistaking
Anyone feel free to correct me if I am wrong
Now, see, if I'd been thinking I'd've made a Nandroid before flashing. You know, like mentally stable people do. Unfortunately, thinking wasn't on the menu.
I flashed Zedomax's 2.3.5 and will do an ODIN -> Stock 2.3.6 -> root again once I touch my Windows PC again tonight.
Learn from my failure! Nandroid now, nandroid tomorrow, nandroid forever.

You don't have to root again once rooted already.
Just flash a stock rom from the T989 dev section. Do a nandroid backup.

You can just flash a theme that's made for your ROM... I had this happen to me when I was trying to make my own theme and had bootloops with everything force closing in me so I instead just flashed a working theme to fix it.

What I ended up doing was using ODIN to return to completely stock, then rerooting and removing CIQ by hand. I'm at the point where I'm not interested in flashing anything save the eventual CM9.
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.

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.

Thanks for the help! I used titanium backup and did a one click to the fi03 version of ics.
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?

Am running CM9 nightly (9.16) and everything works great except I can't get GPS to lock on..just sits there with "searchign for GPS"...
What I've done so far:
- "GPS Fix" flashed from CWM....no help
- "nexusmodempatchcm9.1" flashed from CWM...no help
- "ns4g-radio-KL2" flashed from CWM...no help
- tried the temporarty boot method here http://www.youtube.com/watch?v=g2r7anSiI5I but that was for the Epic Touch and it didn't work or maybe I didn't do something right....it would just hang and couldn't get into CWM after reboot
- finally Odin'd back to stock, ran the GPS fix from the App store and got GPS to lock
- flashed my saved CM9 image from the day before, downloaded the GPS fix from the App store and still got no GPS lock
Is my image from the day before the problem? I thought the GPS fix done from stock would've carried over to the GPS in CM9...at least that's what I thought was the point of that...
Would just flashing CM9 again work? (but then I'd have to restore my apps from Titanium Backup..also from a day before saved)
*confused*
Thanks
Yes. Your image has bad GPS data. From stock with GPS on and locked flash CM9 and do not restore anything and test GPS.

Yes when you Odin to stock you will not have root but you are only testing your GPS. Then leave it on with a lock, Odin cwm 5.0.2.7 with reboot unchecked, when it completes pop battery out and in, 3 finger to CWM and flash CM9 and gapps. Start phone and test GPS. If it works then yes you can restore Titanium Backup stuff but no system data.
GPS works on CM10 without GPS Fix.

This. Went from various Gingerbread updates straight to CM10 mainly for GPS stability actually. Had trouble keeping lock on GPS all the time and used phone heavily for multihour navigation; for like 2 years.... Since CM10 have had 0 issues. It was almost a religious experience.
