Can I swap a Nandroid backup between replacement devices?

If I need to have my Infuse replaced under warranty can I load my Nandroid backup from original Infuse onto the replacement?

Indeed.
At least to my knowledge there should be no conflicts because the backup shouldn't contain any device specific information(unless you're changing devices completely i.e. infuse to atrix or something)

I am new to the infuse so I don't have a definite answer for ya...I know on our other devices it has always been discouraged

Nope, Infuse->Infuse.

MisterEdF, did you ever have to do this? ZeroIsntTheHero says "no conflicts" and 00mred00 says "discouraged". What is the correct answer?
I just shipped my Infuse to Samsung to have the GPS repaired and I would like to know if a nandroid restore is even worth the try if they ship back a different IMIE.

At the time I had just bought the phone...as there is nothing radio specific from device to device I would say go ahead.
The only issue I could see is if imie info were stored in the back up, and I don't believe it is but I don't know for sure.
(sprint phones would be highly discouraged due to wimax keys)

Yes, and it worked perfectly fine. From what I have been told there is nothing in the nandroid that is "phone specific."
However, if the problem you are having on your original phone is software related you will carry it over to the new phone.
I did have a problem going from Froyo->GB but what I did was install a GB ROM first then it worked fine as per one of the devs recommendations .
Whay not just backup USER APPS ONLY with Titanium Backup and restore that. That worked fine on any OS for me.

[Q] IMEI Null/Null?

So, it turns out that my IMEI is missing and I don't have a backup of my EFS folders. My phone works perfectly fine but it has no service. Is there a way to fix this?

I had the same problem... I didn't know how to fix it so I took the phone back and replaced it. I think it might be a bad flash, but I reflashed it a few times and still no use.

Yeah dude, I was getting to the point were I was going to say the same thing as the above poster. Because I am stoked as what to do. Some people here have said that they've had to return their phone and get it replaced by Samsung.
You may have to do so if it is still under warranty if you cannot find a solution.
If a solution hasn't been found, remember that if you will send the phone back to samsung the phone must be complete stock without the root and without the de-odexed files. (I can show you how to return it to stock without root, i wrote up a small tutorial on that.)
Anyway man, I'll keep looking over the forums, if anything comes up I'll let you know. Heck maybe someone will post a solution to your answer soon even before me.

So the problem came up after i tried to reflash the roms back to stock rogers (along with the kernel reflash)
i used the stock firmware from gtg along with his kernel in the HOW to root rogers in the q/a
afterwards, im not exactly sure when, i received the no carrier (no imei, etc) problem. I thought i might have short circuited my phone by pressing the back of the sim card's metal holder but i guess this isnt it. Anyways, my replacement rogers phone is coming in this week and i dont think im going to mess with any custom roms until this is cleared up.
Most likely to be a kernel issue or a modem issue. Have you guys tried reflashing the stock rogers modem? i havent done it because i dont have my phone anymore.

I flashed GTG's back to stock for Roger's many times I've had no problems loosing my IMEI.
I think the only time you can actually loose this is if your EFS folder becomes corrupt during flash, for example if your flashing and the flash suddenly becomes interrupted etc.
Roms are cool and all, I know that (Used to be a flash junkie on my captivate). I've stoped using roms. This phone is fast enough to go without roms imo.

im pretty sure this is what happened to mine, but i cant seem to find any solutions. If i send this back to rogers you think they'll hammer me for it?

Is there a rom on it? If not return it to stock without root and bring it to a rogers store.
Good luck!

Infuse 4g - No IMEI: /null
Happened to me also.
Tried performing IMEI Restoration from mobiletechreview, but my EFS folder gave me different files and there was no nv_data backup.
Would flashing a different rom/kernal help fix this?

i tried re flashing roms but it didnt help. Im pretty sure the efs got messed up after the partitioning of the drive. I was on cm7 and then i decided to go back to stock and bam, got stuck with this no carrier/no efs thing. Im pretty sure because going back to stock required the drive to be re partitioned and this happened. That and i deleted my entire SD to clean it up and im pretty sure that didnt help either hahah.

I also have been trying mobiletechreview's IMEI Restoration but did not have the same items in folders and no nv_data. Has anyone figured out how to fix this problem yet?

The nv_data.bak is in the \efs_bkup\efs\root\afs\settings folder.
Thank me please!

problem: I still can't find nv_data in the new EFS folder!

I have the same problem Imei null/null and the baseband said unknown when the sim is in the cellphone.

I posted an efs fix some months back. Not sure where it's at now. But it is in the Infuse forum someplace.

IMEI issue

Hey guys,
Did some searching but couldnt find anything about my specific problem. Recently installed a couple new ROMs and when I was backing up and restoring between them (with CWM) I somehow lost my IMEI and it was showing as B000000000. I made the mistake (you learn the hard way I guess!) of not backing up my IMEI beforehand, but my first question is how could it get lost by performing CWM backup/restores? Improper data/cache wiping?
I came across the IMEI repair writeup using QPST to manually write a new NV and that seemed to work. However when I rebooted, the IMEI was one number short (ie- my IMEI is 15 numbers and the phone was displaying the first 14 but cutting off the last number) and I still have no service, and I'm not roaming. My second question is, does anyone have any ideas where to go from here??
Thanks!
Mike

Are you sure you followed everything in this post ?

There is stuff in the last pages about downgrading your phones radio if there is issues. I don't really know because I haven't had this issue and had backed up all my stuff before messing with my phone. Either way questions about that issue should be asked in there.
Good luck!

Thanks for moving the thread, sorry about the misplacement. Mercuie - I tried the method you linked me to and ran into an issue with the software. When I plug my phone in, my computer's dev manager sees it on port COM14, and when I run the software there is an option in the dropdown menu to select COM14, but it is unable to connect. The ERI status just sits there trying to connect and if I click anything else in the GUI it crashes the program. A reboot of my phone and computer doesn't help. I have MS Vista with .NET 3.5 installed, but not sure if I have the right diagnostic drivers...
edit: tried using the samsung MEID repair tool again and this time when i try to connect to COM14 a red ! comes up and says "In user or invalid port". Not sure why since device manager is definitely still showing my phone as COM14, but it's not crashing anymore

I think my issue is resolved guys =) The QPST injection worked, I just needed to wait long enough for it to reestablish connection on Verizon's network. Thanks!

just kidding! I jumped the gun with my previous post. My mobile data was restored for about 10 minutes then it was lost again. Not really sure what's going on here and why i have intermittent connection. My IMEI in Setting>About Device>Status is correct.

Probably need to reprovision your phone/sim card.
I don't have the key sequence handy ... do a search in these forums for reprovision.
Edit: Enter *2767*3855# into your dialer. This will factory reset your phone, which includes wiping your internal sd.

thanks for the reply. I backed up everything including my internal sd card onto my external card and ran the reprovision sequence. The phone reset, but everything in /mnt/sdcard is still there and I still do not have service. IMEI/MEID seem to still be intact as well my phone number, but Network is Unknown, Mobile network state is disconnected, ERI version is none, and IP address is unavailable. Thoughts??
Edit: tried the reprovision a second time and now I'm Roaming

Bump.. anything guys n gals?

Don't know if this will help, but try removing your sim card and rebooting phone. Shut down phone, reinsert card, reboot and see what happens.
If still no service, reprovision again.
Edit: If you are roaming, you have service. The roaming prompt is a persistent problem with imei restoration that I don't think has been solved yet.

Have you tried to reprovision since getting it fixed? Also, the tool that is linked that you tried and didn't have any luck with is suppose to fix your problem. I haven't tried it but others have had success with the same problem that you are having.

No luck. I removed the SIM, rebooted and it had nothing, then powered down, reinserted the SIM, and rebooted and still roaming. Also tried another reprovision and same result. I know I technically still have service since I can make/receive calls, but I have nothing in the way of mobile data and don't want to turn roaming data on for fear of extra charges. Is it worth brining to Verizon at this point to see if they can do anything? I mean I don't really see them doing much beyond factory reset and playing with the SIM card, which I've already done.
@HHF2:
Yes I reprovisioned multiple times after restoring my IMEI with no luck. The QPST tool worked to restore my IMEI. I saw the Samsung repair tool had an option for ERI repair I believe, but I was never able to get it to connect to my phone via COM port without crashing.

I would try a different computer if you have installed all of the correct drivers for the computer that you are using.

No luck from a different computer. No luck with a replacement SIM card i got from Verizon. A member in another thread posted about how he was in the same situation and was able to flash a downgraded modem and get the Samsung repair tool to repair his ERI, then flash the new modem again. I will try that route next. If still nothing then I'll probably have to Odin back to stock and see if that fixes it and if not then lobby for a new phone :\

I've encountered a number of people (myself included) who have used this tool (which was made specifically to repair roaming status, mind you), to repair the roaming issue after an IMEI injection. So yes, there is a guaranteed way to fix the roaming issue. No point in getting a replacement handset.
OP: I was able to get the connection for ERI repair after downgrading my modem too, so I definitely recommend trying that. If you can get that to connect, you should be back in business.

Glad to hear! So before I do anything just wanted to verify... How did you go about flashing the downgraded modem? Just placing it in the root of your external sd card, rebooting into [CWM] recovery, doing a data/cache wipe/factory reset, and installing from zip (VRLF2)? Then run the Samsung repair tool and once (hopefully) data is restored, do the same thing to flash the latest modem (VRLHE)? My next step was to Odin back to stock but I'd like to try this method first since it seems to have worked for you.

heres the story. i had been running cm10 for prolly 4 or 5 months. no problems. i wanted to check out liquid smooth rom. so i flashed it. no problems. had been running it for a month or so then one day at work when i went on break my network was gone. my apn's were deleted. came home inspected some more and my imei was unknown as well as baseband and many others were unknown. i took it back to stock many times using. gtg method. using heimdel. using odin. with different stock files. from different websites. including xda. i have tried just about everything to re do the phone. including going back to cm10. and other known working roms. ive *#*#4636#*#* and manually switched to gsm which wont change when i click it it still says unknown.
i dont belive it is a rom problem. i have been overclocked 1300mhz. what else is out there can i try. \

im sorry i need to correct that. i have not been able to flash to any other roms. i didnt go to stock and then cm10, due the the signature deal on cwm. i was thinking of another time i had problems. so no i have no been able to go to jb after the imei has went unknown

Download a heimdall one-click or odin back to stock pack. Open either one up and put your phone in download mode:
- turn off and have the usb cable connected to the pc.
- remove and reinsert battery
- hold both volume buttons and connect usb. Phone should now boot into download mode.
Run program and you will be good. Then look for entropy's dd kernel and flash it in download mode to get cwm.

i noticed i had signal bars. i looked at the imei and its was a number. it was a different iemi then what its supposed to be but there was a imei. baseband was still unknown but anyway i shut the phone done and inserted my sim card. btw its a straight talk sim. and restarted it now im back to unknown imei......

ok so im back on cm10. before i was on cm10 its was giving me the imei which wasnt my original imei. i guess cuz i flashed a efs.tar. but anyway i was able to make a phone call. now im flashed on cm10. and no imei no baseband nothin. i tried flashing the efs again with odin and still nothing. when i do the *#*#4636#*#* it still wont let me switch to gsm. and i cant add a apn.

Seems IMEI was kidnapped about a month after Liquid
Ironically, I seem to have EXACTLY the same issue that this original poster has. I have been flashing my Infuse for a little over a year now and I Flashed Liquid, I'd say about 3 weeks ago, maybe end of November. Everything has been smooth sailing. About a 2 days ago I started noticing that my network would just drop - for no reason. But at first it came back. Ok, no problem, probably just a glitch. However yesterday morning it happened again and then I was without the use of data for most of the day until around 6pm. It came back but the bars were grey but I was able to make a phone call. Once I made another call it did not go through, I tried to hangup and it just hung there. there was nothing I could do to get it to hang up. Rebooting the phone resulted in no bars at all. Nothing, nada, ziltch. So last night I reflash it a couple times and notice that there was an update to Liquid (2.1 beta). cool. I wipe, flash 2.1b and it is beautiful. EXCEPT for the fact that I have no network. wifi works fine, but no carrier whatsoever. GRRRR. I decided to back every thing up (have done so several times in the past), stock back down to 2.3.6. Barebones and all it all looked great until I hung up the phone... Same thing. So I went all Rambo on the phone, wiped it down to the very last compound. AT&T wouldn't know the wiser if they took it from me. Master Reset, wiped files, data, I think I took an IC out with all of the wiping I did... Result? No IMEI, circle with the slash. Upset, disappointed and dejected I slumped back to XDA (after I went on Craigslist feeling my phone was broke) to see if I missed anything. That was where I found some links about missing IMEI. To make a long story short, I DO have an old copy of EFS thanks to QKSTER, but I have no idea how to restore. I swear I have been on this since 6:30am and just now am I finding these threads. Must have gone through about 50 others... Sigh. BTW, along the way of my flashing experience today, my network came back temporarily, but I have not relied on it because I knew it would leave me. Just don't know how to use Heimdall to restore. To make a long story short, using Windows, could someone please help me with how to restore my EFS to see if this would solve my dilemma?

What is the format of your EFS folder?
*.zip
*.tar
just a folder?
If you have lost the signal while on JB, see if you can factory reset the phone.
/settings/privacy -reset
Then put it into download mode.
Use the heimdall 1 click uclb3 and flash it once, then without closing heimdall, check the bootloader box and flash it again.
After this, check your imei and band. If it works, no further back up is needed.
If you're still missing the imei, you can flash one of the gb kernel in the second post to get cwm.
Then use the root pack in post #2,

install a root tool like root explorer (remember to toggle the r/o r/w) or adb and copy the /efs into the phone's root efs folder,

So it is in the .tar format that your script backed it up in. Finding another link on the we (which he also linked back to XDA, http://forum.xda-developers.com/showthread.php?t=1264021 I was able to take my backup (that I used with your script) and follow his steps -mostly- (my/your backup had a 'root' folder that had the nv_data.bin file in the afs/settings folder while the instructions did not mention that. I followed the backup location settings (which in turn was also the same as the default that I had backed up)) and replace the EFS folder. It still did not restore it in any flash image just like that. Still had the the circle w/slash. However while I was still searching and typing out that loooong last passage I wrote, my phone network came back for a little while. I know this because I began receiving a bunch of texts. I was able to make a phone call. But it still happened again when I made another, it did not go through and when I hung up, it just stayed there looking at me with its grey, blank look. Even killing the phone app did not work. I rebooted back to the same drama.
If you have lost the signal while on JB, see if you can factory reset the phone.
/settings/privacy -reset
I actually was on 2.3.6 using your posts, first the basic rooted flash having to then using the Entropy kernel and then I did the lazy flash that was already rooted and just having to add the vold file to /system/etc/blah/blah. I do want to add that I DID have wifi active at this time and it may not be associated, but the first poster did mention he felt it may have had something to do with it. With wifi on, after awhile of me NOT looking at the phohe (actually doing so made me want to HULK SMASH), the network came on and my texts came in. I was able to look in settings and see ATT, and my IMEI. I was almost finished with my passage to you so I decided to update to Liquid 2.1 beta, but moving up to JB, then to LiquidSmooth. Of course doing so I got the circle w/slash, but wifi started restoring my apps.
Earlier I mentioned that I did a whole rubba dub dub, meaning I did do the /settings/privacy -reset thingy, wiping the phones carcass. I will do it again (at this point nothing to lose), following everything you ask to a 'T'.

The weird part is now that I have the flashed, rooted 2.3.6 image and using wifi, at some point tonight my network may come back on. Or it may not.

I wasn't sure if there was a question there.
From my experience, flashing to JB (MTD partition) from GB without going through ICS may result in lost of imei.
Sometimes, it just happens. I had very limited experience with JB.
The few methods that I've tried worked for me. Just simply flashing back to stock with a re-partition ( (Heimdall -1-click for me) usually brings back the /efs and imei without doing anything extra.
If you haven't, and if you can, I would try the heimdall-1-click a few times.
If you want to use Odin, you may need to reinstall samsung drivers and use a different usb port on the PC than the one you used for heimdall.
You may also want to check the signal of the phone at your location. you may be getting poor signal and it has nothing to do with the phone's OS

Me stating that it is bugged out, was me just confirming that it is Weird!

Ok just to explain myself better. I have been saying that I was going from GB to JB when in fact I meant to say that I was going from GB to ICS. Sorry for that. Also, the reason my responses have looked wacky is that I was trying to select the multi quote button and getting no response. Hopefully this response is a little more organized.

See that is what confuses me too. I have flashed back and forth several times at this point, and sometimes the /efs and imei do come back, but now they have never stayed. It is the only reason why I have tried to pretty much rule out a hardware issue. Even when I flash and there is no imei, there is the same /efs folder. And when I wipe the whole thing sparkling clean, even the newly formed /efs folder has the correct imei but it is just not being recognized on the phone.

Of course what I did was accidentally leave my phone home preventing me from testing it out with Odin on another machine. Its all good though.

not sure why you would want to do that..you should be able to get enough from the variety that is available on the i997
each device has their own specific modem
some had reported success using modem from different galaxy device if the hardware is similar
i think the first galaxy captivate modem work but cant vouch for that. it's been almost 2yrs since i recall that topic being brought up
dig back into the older modem thread in the dev and the q/a sections

I did read in another forum that the emg4 modem can fix the signal (baseband unknown and imei unknown) so, i was thinking to flash it

this issue is a different altogether. flashing a modem from a different device over it is unlikely to fix the problem
kinda like trying to fix a accidentally pregnant girl with a baseball bat...
the baseband or imei was prolly from a bad jb flash
bring it back to complete stock may fix it

I tried that too...but doesnt work

the only time I had with a lost emei was a flash from gb to jb without going thru ics..i brought it back to stock gb and it came back.
gb uses rfs - samsung partition. jb moves the partitions around so the emei may seem lost. that's why i think when you go back to gb, it is found again. i think the same can happen to miui and cm7 flash
i've read flash jb 2 or 3 times may also work..idk..can't vouch for that
here is 2 posts in the general section that address the null emei issue...idk..it may help.

you can also try flashing another device's modem you wanted and report back. the worse that can happen is you sending the phone to the repair guys for a jtag flash for bricking it if odin or heimdall wont bring it back

You have left out a lot of details.
Your question was originally about flashing another modem.
Then it turned to missing or corrupt emei.
Is hard to tell a problem when there is not enough detail about how you got there.
Aside from making sure you have the correct apn, until you provide further detail about what happen to your phone, it is unlikely you will have further inputs..
The original answer to your question about flashing another device modem on to the infuse: is not something I would recommend or attempt myself.

yes you right, i change the subject a little, but I had made a post with this problem and there was no response, so, I hope these details are sufficient:
_i was using the 4.2.2 rom slim 7.8 jb for a long time, then i took a trip to a mountain, poor coverage, so, theres a friend who take my cel and she put it in a box full of moisture and strong products such as alcohol (to cure) and it was a little wet and then when i got back to my city, i pass from poor signal to no signal, baseband unknown and ime unknown, but suddenly, every 4-5 days, the signal go back for a instant, and i receive old sms and missed calls, and i get back the baseband and imei for an instant, but then, gone again

this may be hardware issues ex: sim card reader, sim card, connection in phone, antennae etc
especially true when it was running well and then you got it wet and it would read periodically
try disassemble all the phone parts completely, clean off all parts and connection with strong cleaner, dry it in silica, rice, beans for a few days and reassemble.
