[Q] Nandroid backup tutorial?

hi I rooted my phone yesterday I want to do a nandroid so i can revert to original state if i ever have to return it back to samsung, I seen guides online but didnt want to try them incase something is diferent

It's really quite simple. Open rom manager, scroll down, click backup current rom. Don't touch anything till it reboots.
Oh and restoring a backup of your rooted rom won't revert your phone to being unrooted. If you are going to send it in you may need to unroot and lock your bootloader. I've never sent a phone in so I'm not a 100% though.

Yeah i heard about needing to lockboatloader etc i might just use my free phone insurance from my bank and claim a lost phone. Is this the same for kernals i think i had read something as i want cyanogen mod and kernal so i can get voodoo

which model do you have?
they are all safe

2G & i9020a

So we all know not to touch the toggle in CM7 for 2G/3G, I personally found that out the hard way, but I read that you could do it through settings, well now that I tried that, it's even worse. I have reset the phone/changed radios/roms, had my sim card repushed 3 times now, off and on 20 times, nothing will get this #*@#ing phone to find telus again... WTF. anyways, its going back maybe this thing is glitched?

Alright, new phone. SIM card is the same from my other phone, and it's working fine, so there was a serious malfunction in the other one, not sure if it was because of cyanogen or the radio.
Does anyone know how to back up the stock radio?

+1 if you can back up that radio id like a copy pleasee...since there is no official rom for our phones yet Im so scared before trying anything, but I make the jump after hours of reading up lol.

after lots of reading and posting questions, I think we (as in with cdn i9020a) should play the safe card for now and only go as far as rooting and installing superuser. obviously all these custom roms are based on US versions of NS.

If I can get it figured out I will post it up for sure. I think I know what to do, just want to do some more reading to confirm before I attempt it.

Yeah, it's definitely safer, but never as much fun
The phone is fairly new so it will take a bit, things will get better. I just want to make sure I post anything that I find really screws things up, so no one else has to learn the hard way. The kernel and rom seem to be fine, it's the radio that I'm wondering about, and don't touch that gd 2g button, what a pain in the nut sack that is.

Doesn't android backup the radio? Couldn't we extract the radio from a nandroid backup?

No it doesn't back up the radio....if it did I wouldn't be too worried about it. I have no idea how to extract it but can't wait until someone does.

can I restore nandroid on a new phone?

I'm trying to get a replacement of my GS3 tomorrow since the GPS is acting weird. I backed up apps and system data using TiBu and also made a nandroid when I was still on root66. Then I odin'ed back to stock and did factory reset (by the way, that did get rid of the unlocked padlock //relief) so I'm good to go.
The question is, once I get the new phone and odin root66, can I restore the nandroid on the new phone? If not, can I restore any system data from TiBu?
I did search this in the forums and saw a few similar questions. but 2 posts said no and 1 said yes. so I'm confused.

yes you can restore your old nandroid on the new phone..

But depending on the recovery you are using you may need to put it in the correct id folder. I know amon RA uses specific id labled folders for each device (even the same model).

Yes, you can do it (I've done it) but it's not really a great idea.
You are much much better off to spend the time & reinstall everything fresh.

I thought I read somewhere recently that because backups capture phone specific data on Samsung models that you are unable to move a backup from one phone to another without overwriting some valuable individual phone information. I've done it across multiple other model phones and tablets but hear it is Samsung specifically that has issues.
Someone with prior knowledge and/or links to discussion please chime in.

Thanks everyone. I'll err on the safe side and setup everything from scratch.

[Q] IMEI question

Okay So my phones IMEI has been a bunch of 0's since maybe january of this year. I had a efs backup on my computer but someone wiped it and now i dont have that folder anymore to restore it. Ive tried a few one clicks and nothing fixed it..but my question is, can having a bad IMEI have a negative effect on my phome? What are the problems to this? And just so you all know, my phone has been running fine since the number became corrupted. I dont have any of the bad symptoms that everyone else gets.
Keep in mind, im not trying to fix it(i have lost all hope for that Lol) I just want to know what can happen because of a corrupted IMEI. Thanks In advance.

You can't receive or send data to your carrier and that is all.
Once your phone has lost its IMEI it's as good as a iPod Touch.

What do you mean data to my carrier? i wouldnt say its as good as an iPod touch since i can still make calls, text and have data. The only thing i have noticed is that when i log into my tmobile account, it doesnt show what kind of phone i have. But thats all.
Thanks for the quick reply btw.

Well the only way to get back imei to normal is to restore thru 1-click heimdall or whatever method you use to go back to stock.

I know, I've tried plenty of one clicks and none of them restored it. So I gave up on trying to restore it a long time ago. But the phone itself is working perfectly normal.

Check under /sdcard/aroma and see if there's an efs backup in there. If you installed any roms that used my aroma installer there's a good chance your efs partition got backed up.

I also noticed that yesterday before I fixed my imei with my efs backup I couldnt access voicemail at all. Ate you having that same problem?
Sent from my SGH-T959V using Tapatalk 2

I don't even have an aroma folder on my SD card FB lol. But thanks for the suggestion.
And actually, I can still access my voicemail.
Well, i guess im just lucky that everything still works even with a screwed imei number.

dont mean to jack this thread but fb im having the same problem i have the aroma back up how do i restore the efs back up

I'll need to post instructions soon or post a restore zip for you guys. Are you on ICS? It might be easier to try a one click back to gingerbread and to reflash your ICS rom.
Don't expect me to make the zip but maybe a savvy user can give you instructions on restoring the backup using adb.
Basically what you'll need to do if the one click to gb and reflash to ICS doesn't work is:
Flash to gb
Reboot to recovery
Mount /efs
Untar the efs backup into /efs
Reboot and test voice, data, imei
I'd give you specific commands but I'm not at home

ok thanks i dont like the one clicks. when i use them to go back to gb my imei is unknown but when i use your gb starter pack and flash a gb rom it works great so i think ill stick with gb

That is not correct. I got screwed over on an eBay buy, the phone was blacklisted by T-Mobile. I've been running on a null IMEI for months with no problems. Edge, 3G, HSDPA, phone calls, texts: no issues.

Lol thanks for correcting me, as far as I know you can't do stuff with the carrier, but I have no clear evidence of that. But if its working fine for you then I feel bad for other people who has no IMEI and can't do stuff.

Huh, I wonder if it is related to the towers in their area, I've heard also of a person with an SGSIII running on T-Mobile with null IMEI. I have not been able to connect to AT&T, although I was able to connect to them with the original IMEI.

can i flash a modem from another samsung? (not infuse)

Well, unless its a Samsung galaxy s 4g and its nodded for the infuse, no.

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.
