Does CWM 2.5.1.0 backup the modem and kernel? Also will it overwrite the modem and kernel if I reodin then restore??
off note anyone have an update.zip for the eb13 modem?
I would try reflashing the modem to see if it solves the signal and data speed problems
This is kind of what I am wondering. I created a backup with clockworkmod, but I don't know if I'm able to restore back to my D18 backup now that I am on EB13. Or how this works with custom roms. I've looked but can't find a tutorial for clockworkmod. I guess I'm looking in the wrong spots because i've spent hours already..
Not sure on modem but I know reverting my cw backup today did NOT restore the stock kernal on my epic. I reverted to my backup from stock eb13 with no mods besides root and the OC kernal was still there after the restore.

It does not backup or restore the modem either.
So I would have to Odin before restoring 2.1

Yeah, from what I've gathered CWM doesn't mess with the modem. I think it can flash a new kernel though.
I should know this but I haven't tried it. Can I make a backup of my current SRF1.2 ROM via CWM, flash an EG22 rom and if I decide to go back to Froyo simply restore my CWM backup of SRF1.2?
Thanks
yes

Thanks, figured as much.
youll still have the eg22 modem, which will work, but you can odin just the ec05 or whatever modem you want back...
Well, for the most part yes. I do a ton of testing and I have gotten Google Services Framework errors on occasion when restoring a nandroid specifically after being on Gingerbread. It seems totally random though and if you aren't constantly changing setups like I am, you may not have this happen to you

I always have 2-3 nandroid backups to switch between different roms etc. Been back and forth between EC05 based roms and EG22 w/plus kernel like 4-5 times this week alone, and no issues.

I keep 3 or 4 nandroid backups myself. Perhaps its due to the absurd amount of testing I do that it catches up to me (sometimes 4 to 5 times changing setups in a day) that it catches up to me. Its not likely but it is a possibility.

Hey John, with all the switching around and flashing, what method are you using for restoring apps and data? cwm advance nandroid restore or titanium backup or both?
I've been on srf exclusively but with all the cool new gb roms I'm itchin to play around. Also what is your current favorite new rom?

I never restore data from one ROM on to a different ROM. I always do a clean install of apps and such. What I do is flash a ROM, get all of my apps added, set it up exactly how I want it then make my nandroid. Now, when I do restore data I do it through CWM Recovery Advanced/Restore Data Only. I do that (for example) if I install SRF 1.2 fresh then restore data from a SRF nandroid. Now people do restore data only from one ROM to another and don't have problems. I just can't test thoroughly that way because it could be app conflict causing an error. I wouldn't recommend restoring data from a Froyo ROM onto Gingerbread though. Now my Favorite ROM??? Wow that's tough. On Froyo; (in no specific order) SRF 1.2, Urban Regeneration, and ERA ReVolt. On Gingerbread its a ROM that isn't out yet...CompKid's upcoming EG22 release is going to be a big hit. They are all good though. You really have to try them and see what works best for you

I am new to rooting the Epic 4g, but not new to rooting in general. I had an HTC Hero (cdma) and am now on the Evo 4g. I understand all the terminology associated with rooting/flashing, etc, however, the Epic is a little different. I just rooted my wife's ECO5 Epic using the most recent One-Click method and everything worked great. The first thing I did was make a backup. I would like to flash Syndicate Frozen 1.2 but am a little confused on this whole files system jargon as it isn't existent or an option on the EVO. My questions are as follows: If I flash Syndicate Rom 1.2 and the Genocide kernel, I understand that it will convert my files system to Ext4 automatically, but if for some reason I don't like it, can I simply recover my backup in CWM and go back to stock? Or do I need to ODIN back to stock and reset up my whole system as I had it prior? I see that the One-Click 3.1.0.1 method I used has dual file system support. What does that all impact? Just new roms or my current ROM. I have done a bunch of research but haven't been comfortable in my findings enough to start flashing. Can someone please clarify this for me?
I believe there are scripts available to convert between the two file systems, in both directions.
That said, EXT4 is the way to go imo. Don't be shy about it. Sfr 1.2 is top rom in my book. Do take the time to go get the other goodies as well. Hotspot hack, and the supercharger script. It's all amazing when it comes together.

Clockworkmod 3.1.0.1 does not restore filesystem type (ext4, rfs). You can either odin back to rfs or flash a .zip in Clockworkmod. Also, if you have access to odin, there is NO WAY you can brick your phone. It will ALWAYS be recoverable.
(unless you intentionally brick it, there are ways)
So just to clarify, I must ODIN back to stock and thenin recover my backup, which is just stock? Or, can my stock backup run on Ext4?

Best to restore first and do the conversion, but there is no reason you can't restore after. Although I usually do advanced restore data between file systems myself.

Will the completely stock rooted rom run on ext4? Or is my backup useless unless I convert back to rfs file system?

If I remember right, stock runs on ext4. As long as you have a different kernel. Stock kernel does NOT run on ext4.

That is 2 different questions. One no stock kernel is RFS. Two, restore as I mentioned before, advanced restore data only and you will be fine. You may have to set up your accounts but that is about it.

I think i need to ask the question differently. Right now, all that I have done since getting her the phone is complete the One-click root 3.1.0.1. I then made a backup. I haven't done anything else or made any changes. If I now flash Syndicate 1.2 frozen but want to return to my backup, are you suggesting I don't need to ODIN back to stock, but simply advance restore in recovery? Sorry for being an idiot about this guys, but like I said, I am an Evo flashaholic and its taking me some getting used to speaking Epic language! Plus, I would hate to flub something up since its my wife's phone!

I think what I am looking for is step by step what is the shortest easiest way to "undo" a new rom flash and go back to exactly the way it was before. On the Evo, a nandroid backup is gold and does just this, but I am finding that on the Epic this isn't as simple
Sent from my PC36100 using XDA App
I would not start with SRF 1.2. Because you also need to flash a kernel. Start by flashing a ROM that comes with a kernel. If it is for someone else keep it simple like ReRFS ROM. I would not even do EXT4 unless you are sure you have journaling enabled. The first freeze, drop or battery pull will cause Force Closes galore. Unless you are planning on supporting that phone constantly, keep it simple. And yes most times restore works fine without goling back to Odin.

Yes, I agree, but "if" I flash an ext4 rom/kernel and then try to recover my stock rooted backup from cwm, will it work since stock is rfs?

Nand doesn't care what the file system is so yes. The issue you may run into is incompatibilties between ROMs and data. So go ahead. I run both nands and Titanium backup just in case of an incompatibility so I can go between froyo and GB.

The answer is no. Complete stock kernel doesn't support ext4. He would have to flash genocide or twilight kernel.

Doesn't matter if he did an advanced data restore. It does not restore the kernel.
Also I am not sure it restores the kernel on a full nand restore. Did one recently and none of the kernel mods restored. Had to reflash my kernel. I thought 3.1.0.1 was supposed to backup and restore the kernel.

That doesn't make sense, if it didn't restore kernel, then how can some people nandroid between cm7 and eh17 every so often? And yeah, but I think he was talking about restoring the ROM, not his data. I could be wrong.

I am confused as to what the OP wants then. I thought he wanted to flash a ROM and if he didn't like it restore back.
As for CM7 to EH17 and back, simply flash and advance restore data or use Titanium Backup. I backed up Hurricane after flashing a new kernel and adding some mods. Upon restore later the first thing I noticed was the mods missing. This is with 3.1.0.1 Odin'd in. Had Bonsai recovery which does back up kernel image as well but would not flash other EH17 Roms for some reason.

I'm confused. The op wanted his phone to be " if for some reason I don't like it, can I simply recover my backup in CWM and go back to stock" which I assume is complete stock, which means the ROM and not his data.

He further confused me later on but going by the OP, then you are right and the best bet at that point is to Odin a prerooted stock ROM like EC05plus to save a step and then restore everything if he didn't like SRF 1.2 and Genocide.

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?

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.

I'm new to Samsung Android phones, and new to the E4GT, so I need a little help.
I always flash the zip for the EL26 CWM5 recovery like instructed, soooo, here is my issue.
I'm running AOSP and thought I would try CM10 JB, soooo, I flashed into EL26, performed a full nandroid to my Ext SD. I flashed JB and gave it a shot. For issues known to all, I wanted to switch back
So, I went into recovery, flashed the EL26 recovery and rebooted recovery, I then restore the nandroid backup I just made, rebooted, went to the Samsung screen (with the yellow !). After some time, about 20-30 seconds, it goes to a black screen indefinately until I pull the battery.
Any ideas? I have yet to get a nandroid to work on this device. Had no issues at all on my 3D. I'm sure I'm doing something wrong.
TIA,
Tee Jay
You need to flash the AOSP kernel. Well first can you boot into recovery or download mode

Yeah I can get into recovery fine, so I flashed an AOSP kernel and then my wifi didn't work.

Nope, won't even turn on. But if I do a full clean flash of the exact ROM, it works fine.
I'm by far no expert but I'd say the kernel is being replaced by the gb recovery kernel when you flash back for your safe recovery.I personally keep a couple various recoveries so I can nandroid backup on the kernel native to the Rom and then the backup will contain the proper kernel.I think I got that right.so....nandroid b4 recovery has been my habit.
Had this issue before, minus the yellow triangle....anytime you're on an aosp rom and do a nand via el26, the nand stores the last kernel used (which is GB el26). After you restore, wipe cache and dalvik and then flash an aosp kernel, probly one from chris41g. Reboot and should he good to go.

Right, I tried that with my AOKP backup, I was able to boot. But then my WiFi wasn't working because of something to do with the Kernel I'm assuming
