CWM and modem - Epic 4G Q&A, Help & Troubleshooting

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.

[Q] Help! Can't flash anything!

I searched but couldn't find this particular problem; any help would be greatly appreciated.
Over the last few days I've downloaded midnight 5.5 and the new Urban fury (each three times; 2 times from different computers and once from the phone) and everything I flash just hangs at the Samsung boot screen. I've odin'ed back to EC05 and tried, always wiped everything 3x....nothing is working.
I can restore a previous backup just fine but that's all that works. I'm on the EC05 modem but also tried with the EF02 and EF10 (?)...the update from 02 anyway. I'm using the purple nurple for recovery.
Any ideas because I'm fresh out. Thanks!

Did you odin to stock EC05 or just the modem?
Sent from my SPH-D700 using XDA App
I guess that part wasn't clear; I odin'ed the whole ROM and it switched me back to the EC05 modem in the process.

Aren't those EXT4 ROMs? You need to run the EXT4 conversion script first. CWM 3.1.0.1 does not convert for you like the older clockworks.
That's a good point. I'm not sure how that works but before the odin ordeal I was on EXT4 and tried wiping and flashing. After odin'ing I suppose it would switch back to RFS but how then does that handle my CWM restore as it was EXT4 when it was backed up? Does the restore change the file system as well?

Just to cover all of my bases I downloaded and flashed the RFS2EXT4.ZIP. I assume that it worked, at least it backed up and flashed to "complete" but after wiping and attempting to flash Midnight again it is still hanging at the Samsung screen..

Restore your system to a working condition with no FCs, run the RFS2EXT4, don't wipe, flash Midnight. The problem with restoring a nand from EXT4 onto an RFS is the new CWM restores the kernel as well which would be EXT4 only. So anytime you need to restore from a Nand, choose advanced restore and restore data.
I tried re-flashing after getting back to a stable backup but still had no luck. I then downloaded Frankenstein ECO5OCE directly to the phone, wiped 3x and flashed it and it booted up with no problems. I'm still not sure what the problem was with the other two. It's hard to believe that all 6 were bad downloads. I think you're probably on to something with the file system train of thought.
Either way, I'll give this ROM a try for a while. Thanks for all your help.
per the 5.5 thread - Bonsai recovery works best with the 5.5 Midnight fixed. CW wasn't working so great for lots of people.
Thanks for pointing out the problems others were having. I actually was able to flash Frankenstein fine and SRF 1.2 fine today. At least I know that my phone's not jacked; I'll try Midnight again shortly I'm sure. I've always had good luck with Rob's ROMs. Thanks again everyone for the help.

[Q] Can you CWM backup SRF1.2, flash EG22, then CWM restore SRF1.2 without any issue?

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

ECO5 help

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.

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.

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.

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.

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.

Question about updating profile

Before I backed up my stock rom and flashed my current one (PACman) I updated my profile just to make sure that I was good to go for a while.
Does the profile updates/PRL updates done in stock stay once you wipe everything and flash a new rom? I'm wondering because I don't get quite the signal strength that I did in PACman that I did on stock and I have no way of updating my profile inside of PACman. But, if profile updates don't stick after a wipe, what good does it do to go back & forth?
I really wish a dev would come out with an apk for each major carrier to update profiles.
Yes it does stay. When changing modems you should update again though.

So, just restore back to my stock backup with my current modem and update...then, restore back to my PACman rom backup?

Can't Update Profile
I just recently installed a JB 4.2.2 ROM from rootbox and have been unable to get my profile to update, so in turn have been unable to connect to 3G. When I got to About Phone -> Sprint System Updates the update profile option dials *22805 which never activates my phone. It just dials the Sprint customer support number.

Well, I just flashed my recovery and it won't boot past the S2 logo now. Did I miss something?
Okay, more questions!
I tried restoring my nandroid I made after rooting/kernel/ICS modem and it appears to restore correctly in CWM and then it won't get past the S2 splash screen. I did it first without wiping/factory reset and it was a no go, and then I was duh...and wiped/factory reset then restored the stock nandroid...still no go.
What am I doing wrong? In the meantime, I just restored a PACman nandroid and that went just fine and I can use my phone again.
I've been trying to find the answer myself, but the only thing I've found is that the stock recovery has to be restored on the same version of CWM it was created on. How do I do this since CWM updated itself to v6?

You flashed the EL26+CWM kernel to make the original nandroid correct? then just flash that kernel (with PC or mobile odin, doesn't matter) and then restore the nandroid.
BUT, you can skip this if you want to stay on PACman. @bilgerryan has an app somewhere in the forum that attempts to add the sprint update functionality back in to AOSP. Almost everything is broken (including PRL write and Update PRL OTA), but Profile update works without a hitch.
ALSO, take a look at the gps link in my sig. I have a link in my OP there for how to set up multiboot on the Epic Touch. That way you can multiboot into EL29 to do things like GPS lock, PRL update, Profile update, dialer codes, etc.

Okay, I will try to find that app. My PRL is up-to-date so yeah...all I need to do is update my profile, but I'm with Virgin mobile. However, I did flash the FL24 modem (sprint). This will update my profile with VM?
I decided to just try your first fix where I reflash the EL26+CWM5 kernel and flash stock nandroid. After I'm done updating things and want to go back to PACman...I simply reflash the PACman zip (to get back my PACman specific kernel) and once restore flash a backup to get all my apps & things back, right?

Well, that didn't work for me. :/ I reflashed the EL26+CWM5 kernel in mobile odin and then restored the stock nandroid. This gave me the S2 splash screen and just sat there. So, I guess I have to find that app you spoke of.
Okay, I found it, and followed all of the instructions to the "T" and when I click on Sprint System Updates, it simply makes a phone call to Sprint with a voice menu. :/
Update: Okay, I see it is also in the app drawer, but the only thing that currently works is the MSL retrieval.
Sigh...
Download the kernel or the rom and just flash over your restore. Your eecovery is bundled with a gingerbread kernel. So the backup you made is trying to run a gingerbread kernel. Wont work. If you flash the rom over your nandroid it will boot. You will have all system setting restored though. It sucks. But it worka.

I'm feeling a bit dumb now...
I don't quite understand the first part of what you are saying. I do understand that my nandroid cannot run without the GB kernel I made it with. So, I did reflash the GB kernal with mobile odin and then went into CWM and restored the nandroid...still didn't work.
Am I misunderstanding?
Yes. After restoring the nandroid flash whatever rom you were on again. Do not wipe. So I believe you are restoring pacman. After your restore pacman. Use the same recovery, and flash the same pacman rom again. Basically you just need the pacman kernel. Not sure if there is a aseperate kernel somewhere. But flashing the rom over top without wiping anything will restore the kernel back to what its supposed to be.

Okay, new approach...
