Flashing just the modem with Odin doesn't wipe anything, right? - Epic 4G General

As long as I leave repartition and all that other stuff unchecked, right?
(I checked through the board, couldn't find the answer)

No it does not, but just in case you should backup your stuff, if you encounter a problem, you should be good tho, i updated the modem no problem, no data loss..

I flashed just the modem with no problems but like david said a nandroid backup is always ideal before flashing anything.

Actually ive been fed up with clockwork backups, i started just put titanium back up on schedule at 3 am to back up all apps and app data and account stuff, nothing at all for the system as i can just wipe data reflash the rom fresh then use titanium backup, just to restore apps and important app save and account and thats it..
Clockwork has given me to much trouble and also annoying to back up all the time where as it takes forever, where as its backing up in titatanium back up frquently every day, and never have to worry about losing anything if i need to odin, wipe or what ever.
Clockwork has failed to restore properly and still gives me fcs that i occured before and after the nandroid restore.
i just got sick of it so i switched my back up method

Is Nandroid 100% original backup ?

Asking because I never had reboot before and after restoring with Nandroid I get reboots and some errors in navigation
nandroid doesn't change kernel, recovery, baseband or radio.
it does restore everything else.

I didn't change any of that....just applied lag fix and then did nandroid restore. Never had a reboot issue before......I have to say that restore point was NEW flash odin install with root, before I had original unflashed phone.

Can you clarify what you did there? Not sure I understand.
I'm trying to determine whether or not a lag fix (ext2 loopback file) will survive a nandroid backup/restore onto a new stock phone. I'm thinking that the safest thing would be to backup with Titanium, undo the lag fix, make a nandroid backup and restore onto the new phone. THEN, apply the lag fix to the new phone.
Perhaps I should leave this nandroid backup out of it altogether with these lag fixes. It seems we are asking for trouble. At least with Titanium, most everything will be backed up anyway. And then, they can be restored onto a bare, lag fixed phone.
EDIT: It appears there are several who are having problems restoring a Tit backup after a lag fix, which really makes no sense as to why that would happen.
Installed fresh rom with odin. Did one click root. Installed all my apps from market and removed bloatware. Backedup. Then done lag fix and then undone it, but just in case also done nadroid restore.
Personally and I do mean personally before I do anything out of the ordinary like Lag fixes or hacking away at any of my files I create a Backup via Clockwork. Of course they live on my SD card, but I also back them up onto a PC at home. With my G1 it would trash the SD card all the time for some odd reason so it was smart to rebuild the partion via RA_Recovery and then just copy over the Nandroid backups and flash away.
Always inportant to tag each backup with a quick discription to make sure you know what is what because dates do get confusing.
2010-08-09-Time-BFR-Lag = 2010-08-09-Time-Before Lag Fix
So if I screw things up I can easily restore to that point because one reason or another I'm not going to be happy. Heck if I decide I'm not to sure about a fix I create another backup 2010-08-09-Time-AFR-Lag = 2010-08-09-Time-After Lag Fix
I now can test before and after and restore back and forth constantly until I decide what I want or where I want to stay.
Heck the first thing I did after I installed ClockWork was a backup, which would put me right back at Stock minus some of the bloat apps.

Why are my Clockworkmod backups unusable?

So, I just rooted my Mytouch 4G a few days ago using the 'Ultimate' guide on this forum. I had root access and I disabled and deleted some stock apps from my phone. I was using LauncherPro instead of the HTC Sense launcher. I made a backup in Clockworkmod recovery immediately after installing Clockworkmod, before I'd made any major changes.
So, I spent the past few days removing and tweaking things. I had my phone working extremely well. But then I realized that I actually wanted an .apk file (the stock visual voicemail app) that I'd already deleted from the phone. It should be in my original backup file, right? So I figured that I'd make a new backup, restore my old backup containing the .apk file, copy the .apk file off of the phone, then restore my recent backup. Well...this didn't work.
When I restored either the original backup or the more recent backup, the phone would boot up and I'd get a message that the System UIDs are inconsistent. The phone would let me make phone calls, but 95% of my apps were missing from the loader. Most of the icons on my home screens were grayed out and would tell me the applications were missing when I tried to click on them.
I tried Fix Permissions in Clockworkmod recovery, but it didn't help. My Android Market app and all of my file manager apps didn't work, so I couldn't reinstall any apps. When I'd wipe all the data on my phone, but only restore the System backup, the Android Market would work and the phone basically returns to stock. But as soon as I restore my Data backup, everything breaks.
At this point, I've already wiped the phone and started over from scratch, but I'm afraid to rely on Clockworkmod/Rom Manager for backups again. Any ideas what went wrong?
did you flash a different kernel? this may be the issue, as I know that for other devices CWM does not restore the kernel.
this happens when your backups/card gets corrupted... it could of been a number of things... changing the name of something to how much you scan the card... hard to say exactly what caused it... If your really worried about it I would suggest making a backup of your backup on your computer just to be safe...
Hmm. Mine does.

I did make a backup of my backup, but it's not like these backups sat on the memory card for months before they got used. I ran the restore within minutes of when I made the last backup. Besides, aren't the backups hashed with md5 and then retested before restoring? So, if the files did get corrupted, I would think Clockworkmod would have notified me, no?
I just wish that after making a backup, there was some way to test it out without taking the chance of trashing my phone.
Regarding using a different kernel, I did not. I did not flash any experimental/downloaded images, these were simple backups and restores of my existing phone data.

This is for phones that dont support Nand like the vibrant. HTC phones is a full backup including kernel.

Your right, CWM does do a md5 check when restoring. I'm sorry, I don't know what could be wrong. I currently have like 5 backups of 4 ROMS and have to restored to just to play around. Did you do apps2sd? This can cause major issues when switching ROM's.
I am also having a problem restoring to my stock rom. how big does my backup file have to be?
I have had this problem before. I think in my case my issue was caused by and incompatible version of CWM. I found that to be safe, I usually make two back ups, one with recovery in 2.5.12 and one with 3.0.0.6.
It was the file. It was only 60mb, apparently I ran out of memory thanks though my other backups work fine and I found the stock rom on a thread.

Keep my data after flashing a custom rom?

Forgive my ignorance.
I am following randyshear's excellent video and just rooted for the first time and wish to flash viperrom 4.0.2.a.
The only question I can't find an answer to is whether I can keep all of my data intact (my email accounts, the apps I've downloaded, etc), or whether this process will completely wipe out my data?
Maybe I'm already on the right track? I booted into clockwork recovery and selected "backup and restore" and made a backup to my sd card. I copied this nandroid backup to my PC. Will I be able to "restore" this after I flash the viperrom?
Thanks and sorry for the ignorance!
I prefer Mybackup Pro over Titanium.
Yep, my back up pro, or the free root version.

Or once you install your new ROM, you can boot back into recovery, go to backup and restore, then advanced restore, and just restore your data. This should restore all of your apps, settings, sms, ect without messing up the ROM.

I have flashed several roms several times waiting to find that ultimate rom that I cant live without, everytime i have had to try and figure out how to get all my data back, will this method work without fail? have you done this before. please let me know, if this is true you will have become my new hero. thanks
If you are coming from 2.1 or any other rom then data restore can cause fc and stabilit problems. I'm not saying this happens to everyone on every rom but it has happened to me multiple times after wiping data/cache 3 times flashing the rom, booting, clockwork data restore etc.. I generally don't try it anymore as it caused more problems than it solved. Just my 2 bytes.

Newbie needs help/info

I have a T-Mo G2 and want to keep my Froyo image to reinstall later if I cannot get theGingerbread to work right. I want to make an image file that will restore the phone to exactly how it is now. I have tried all kinds of stuff, but am not able to make the "img" file so that I ca do a restore when booting...
Can someone point me to what I need to install to do this, and if possible some directions on what/how to create the "img" or restore file ?
I would be most appreciative, as I had to reverse everything from the OTA of Gingerbread, since too many apps didn't work, ESPECIALLY the GPS!
My current Froyo is a temp-root system.
Thank you all!
Aloha. .
I would do full root via the wiki, and then install 4EXT (the full one that's like $2) - it will keep your old stuff straight
Ditto on previous reply
Root your G2
Backup all your apps with using Titanium backup
Get Clockwork mod ROM manger or 4ext ( I prefer 4ext) and backup your stock rom. You can download new ROM CM7 for first ROM.
If you don't like the ROM you can restore your stock ROM with CWM or 4ext at anytime.
I have a theory that Ti Backup or any backing up of apps is a bad plan. I know you can do it no problem, and that it is a great time saver, but I have a strong feeling that this ultimately results in an unstable phone with mysterious force closes etc.
Even though it's a real pain, I think you are always better off reinstalling your apps from scratch after changing to a new ROM and wiping caches.

1. I have had zero problems with TB personally.
2. Without it your app data is gone.
3. Triple wipe, takes a few extra minutes and makes a world of a difference.
4. Do not restore system data!
5. Check md5 sums BEFORE doing anything!!!!
6. Make sure you have a recent nandroid backup and you'll be fine either way.
7. triple wipe before flashing anything including nandroids. Preferably with different wipes aka factory reset, superwipe+ ext4, then recovery wipe!
Just my 2 cents, it's saved my a$$ more then a few times...

Backup restore problem

Hi all... tonight I decided to try the Samurai kernel. Unfortunately, it boot-looped on me. No big deal I figured, I did a full nandroid before in ACS's CWM, so I'll just restore. Unortunately, doing so isn't working: all of my apps, data and settings are gone! It basically looks stock (although, interestingly, all the Sprint bloat I had manually removed before still seems to be gone, so the restore worked to a degree)... I've restored backups before and never had a problem so I'm guessing the kernel is somehow the culprit, but I think that got restored from the backup too so I don't know what's going on. I'm stock EI22 by the way.
Can anyone help me? I'm pretty frustrated at the moment.
Thanks,
Frank
Try restoring an older backup. If that works you can attempt an advanced restore data only from your recent backup to see if it was something in your setup.
Sent from my SPH-D700 using XDA App
That was a thought I had too... I tried TWO older backups that I still had, same problem. I also tried a factory reset and then a restore (in theory it shouldn't make any difference to factory wipe first, and sure enough it didn't, but figured it was worth a shot).
My only other thought is maybe if I odin back to stock, root & install recovery and then try the restore again... kind of a shot in the dark, really shouldn't matter, but maybe.
Did you clear cache and dalvik before flashing the new kernel? I wonder if ACS is the issue and if trying CWM 5 might help.

I was thinking the same thing D. The only other thing I can think of is bad reads from the sd card.
