what is nvflash actually for? - T-Mobile, Samsung Galaxy SIII

ok so what is the text file for when doing a nf backuo? does it restore the device from a hard brick? i just did the backup and just wanted to be sure what it was for

reboot nvbackup? Backs up IMEI, basically. There is a lengthy post (in the IMEI restore thread) about how it actually works.

Basically when flashing your emei may randomly dissappear meaning you won't use the things that a phone is for such as calling or texting. If you can't restore it only way is to replace it. So good thing you backed it up because often that gets fo gotten and is really the most important thing. Samsung phones always have to deal with these issues.

nice thanks. i also have the transformer prime and they also found a way to do nvbackup and in their post it said it helped recover from software bricks including bootloader. so i was wondering if it was the same for the s3.

[Q] To devs or anyone...please help!!!!

Here's the problem . My friend has an Stock Epic 4g and it eventually bit the dust. She can still access the download screen via 1+power buttons but other than that her phone won't turn on. Now, thats not the problem. I can fix that. The problem is that she had very important text messages in her phone and we're trying to see if there's a way to retrieve them before I "unbrick" her phone. has anyone found a way to pull info off the phone before undergoing restoration and deleting everything? I apologize in advance if the answer is already on here somewhere. I searched and came up with nothing in our forums except for the text message history viewer on sprints website that is no longer there and besidesm even if it was, these texts are from around christmas. Any suggestions or advice would be greatly appreciated. Thank you
I think you're pretty much stuck. I had the same problem once and never managed to get it working. If you can somehow make a backup of the messed up system that would be great. If the phone is stock, I don't think there's a way to do that.

no, there's not. I thought of that too. I was wondering if maybe i plug the phone into my computer maybe there's something that can take everything from the phone and copy it to my computer? or even just view the system folders in hopes that I can get the text messages that way but i dunno if that's even possible.
No. She's screwed. Tell her to back up next time.

OUCH! When I give people bad news I at least hand them a bottle of petroleum jelly first! Yes this is an attempt to make a very dry (or is that wet) joke! Sorry had to.
On topic I don't know if you can mount the system w/adb once it is in that state and k0nane would know more and if he is saying no I doubt it.
I am by no means an expert but... could you odin in the recovery, get into CWM, make a backup, extract the data image, pull the messaging data and then restore after getting the phone functional?

Wouldn't that just reflash the recovery partition? OP: Try this if you haven't just reOdin'ed yet. It wouldn't damage the messages any more than they already are.

That is what I was going for, just overwriting the recovery partition like you would for rooting GB. You could even try to bring it back to life by flashing a kernel and see if it would boot. Neither of those operations should delete data.

I agree with the above. Don't odin it, try reflashing the recovery partition, nandroid everything to sd, THEN unbrick, restore data.

Make sure you tell her that her boyfriend still loves her even though the text no longer exists.
Download google voice from the market and you should see your texts there. For whatever reason, all my texts have been saved even though I've wiped my phone many times for different ROMs.

[Q] Need to reset Android ID (resolved)

After flashing a new rom, ran into a problem I have never seen before. I could not restore my apps from Titanium Backup. It won't even list them. I know I have the directory set correctly. Even had TB search for the right directory, and it shows files there, but when I go to do anything in Batch nothing shows up. Not even currently installed apps.
Wiped, format, etc. Flashed a different rom. This time when installing TB it comes up with a screen telling me my android id has changed. Still can't restore anything. TB said it could fix it, but only if you have premium version. (Wife just got laid off, so money is tight, otherwise I probably would have bought it.)
Googled the hell out of it for a couple days and pretty much came up empty. Android Id changer in the market it not compatible with this device. Seen people mention editing build.prop I have no idea where to even look for build.prop, let alone what to look for inside of it.
Another interesting thing I noticed while going to Play Store via my PC, I now have 2 different E4GT listed as possible devices to install to. This seems to confirm the changed ID.
Any help would be greatly appreciated.
We need to know what rom you're using that broke it.
Sent from my SPH-D710 using XDA
Went from cm9 to Frankenstein. Thats where the problem started. Wiped all and currently running touched by sgsiii. If it helps, my new id is the same as my serial number in about phone.
Sent from my SPH-D710 using XDA
From what I'm reading the MEID is your android ID. I think it's also printed on the box you got the phone with and also under the battery. It should not be the same as the serial number.
And you still have service?
Edit: Have you tried one-click back to stock rooted EL29 GB yet? I think you really should start there to see if the reset resolves the issue on its own.
Also the info I put above is incorrect about it matching yourMEID.
No, its not the meid. It is a 15 digit hex number. Same that show in about phone-> phone status. Serial number. I can pm you a screen shot. I dont really want to post that info out in the open.

Stuck on Edge!!!

Hello everyone,
I wonder if anyone can help me. I have a rooted Samsung Galaxy S III from T-mobile, running CM 10. Since last week I've been having trouble with it after I updated the CM 10 rom. For some weird reason I cannot receive calls while I am using my data connection, incoming calls are always sent to voicemail. I tried the ##DATA# code to try to turn off the DDTM mode but later on I read that I cannot access this menu unless I am on stock ROM, I tried to flash T-mobile's stock ROM with Odin but the process kept getting stuck with no progress at all.
I kept looking and I came to the idea that my problem was my IMEI, which when I checked, was 0. I restored my IMEI and now I have my IMEI number and everything but I my internet connection is still stuck on EDGE and I cannot receive any calls. I even tried updating my modem I tried several different T-mobile modems for my phone and none of them can take my phone off EDGE.
then I tried changing the network type with the *#*#4636#*#* the actual network type option that it has selected is WCDMA preferred, I went ahead and selected LTE/GSM/CDMA but that option doesn't stay!!! I am going nuts here!!! I want my 4G connection back, I have tried everything with no luck at all.
I just hope that somebody out there has gone through this and found a solution cause I am losing all my hope and I don't want to take my phone to T-mobile since I cant flash it back to stock rom.
If anyone here could please help out I will be extremely thankful.
Thanks in advance.

It's more to it than simply injecting your IMEI. You have to inject it, back it up, and then restore it.
Well i had to enter my IMEI manually to generate a .txt to write it to my phone because the one i had before was corrupted cause it was 0.
Was thete any other step that I skiped doing?
I figure i wouldnt make a back up before injecting my IMEI manually cause i didnt have one.
Am I screwed??

Yes, you skipped two complete steps. There's three steps, again, Injection, Backup, and then Restore. Go back to Peoplearmy's thread and follow it completely.

I did this method, I cant actually check if my 4g is working since unfortunately at home I always get EDGE so I will check later when I go out.
I have a question, I did check on the dialer my IMEI but I saw a picture of somebody on peoplearmy's thread and their IMEI included a /0# at the end and I realized that mine doesn't.
Does the IMEI need to have that /#0 at the end in order to work or is it ok? I just want to make sure since I can only check my connection speed when I go out.
thank you

As far as I know, your IMEI should just be a simple number. If the IMEI you're seeing on the software matches your IMEI on the back of your phone, then you're good in that department. If you also followed the steps for the backup and restore. Then you're good. The backup is important, because it allows for the restore. The restore has some (stuff) that adds all of the settings back to allow you to connect to 4G. Does that make sense? It's a three-step process when you lose your IMEI for the first time.
Inject, backup, restore. It has to be done, because the restore really does add something back to make it work properly.
Should you lose it again in the future, you can simply just restore and be right back.

[Q] Huh... I've tried digging up stuff, but I think I need some advice

Howdy folks, I think I'm in an odd situation here...
I have a Note 2 from Videotron that's been unlocked (they won't warranty it, Samsung's given me the run around), but seems to have developed an odd issue... Basically, I'm running stock firmware, but have been rooted. However, my phone gave up the ghost the other night and I figured just flashing the stock Odin image (from Tesh) would just resolve it.
Well, it got my phone back up and running... sorta. I can't seem to access the inernal storage (which isn't a big deal as I have 32gb micro SD card), and somehow my IMEI number shows up as 'null'
I did some digging around and I found out about the nv_data.bin (and related files), so I decided to dive into the EFS folder and lo and behold... those files seem to be missing. Wifi and bluetooth check out as functional.
I've tried some of the tricks to rebuild it, reflashed the stock image, modem, csc. and no dice.
I've seen talk of being able to hex edit the files from another device to get it up and running, which I don't mind doing. I've been flashing ROMs for a few years now and this is the first time I've encountered this. Also, I'm an IT tech by trade, so command lines fon't scare me.
However, this is stumping me and I really don't want a $730 mini tablet... or if you folks know of a service that rectify the issue for me, I'd appreciate any info. Though, I'd prefer to DIY myself before sending it out to a shop.

That would probably solve my issue other than the fact that the one tool I need (here) keeps 403ing.
If someone sent me that tool... I might be able to fix my IMEI issue and be done with it. Otherwise... I'm contemplating of getting a crackberry Z10 and be done with android...

Kies doesn't really backup the device, it just copies out media. Backup implies "data" as much as any other adjective I can think of and app data is one thing Kies does NOT backup for sure. Samsung "Smart Switch" is a sham for the same reason and they don't make that clear. A less informed user wouldn't find out until they tried to "restore" to a new device and found that much of their app-data (preferences and game-progress mostly) is not there.
Well without root I don't believe there is any other way to save app data such as game-progress and preferences as you stated. If there is a way, then what would you suggest?

adb backup is the only method I know that doesn't require root. Same method that Helium relies on (which I am now trying), though i think it's taking another approach to getting the .ab file because it seems to be storing on the device, not desktop just yet.
My adb issue doesn't seem to be preventing it from making progress, but it's slow and not remotely done so I can't claim success yet.
Give Helium a try. No root required, and while it's not Titanium Backup it's pretty solid for just backing up & restoring apps.
(of course, now I see it was already mentioned)
I o ow this is an old thread. But, her is how I did it with mine. Download Titanium Backup and SuperSUme. Next, Kingroot. Root with Kingroot, go to SuperSUme, run it. Then go to Titanium Backup. Run that, back everything up. When it is done, move all other the files in its chosen directory onto a safe place. Like a computer or thumb drive. Reset your phone, then after you have set up your Google account, download Titanium Backup, SuperSUme and Kingroot. Put your Titanium files back where they were before. Re Root, and restore your files one by one. That way you do not add unnecessary ones back. Also, after a rest of the phone, you might have to run the Ddebloater script again to stop the OTA's. I'm sure that the OP has by now figured things out. So this step by step is for those that are looking to do the same. If any one else knows of better, by all means, let us know.

Truthfully, if the "Chinese" want into your phone. They will be in there. Think about it. Where are your phones made and programmed? Yup, that's right, China. Now, does the Chinese government have a history of providing that they can not be trusted? Absolutely. But, sorry to burst your bubble. Every government has thus far proven to be the same. And the United states and British governments are worse. So, try to hide whatever it is we want to hide. Doesn't matter. There are probably more back doors into your life regarding our electronic devices than we can imagine. And there are soon to be more when legislation passes a bill locking down firmware for WiFi routers and cellular routers. Of which, our phones have both. Will they be locked down to protect us? They say so. But, we all know that it will be so that the development community can not patch these back doors. Any way, I went off point a bit. I have been using Kingroot and SuperSuMe. A lot of us have been. Does it put us at a potential risk? Yup, potentially it does. But, I want my data to be backed up so that just in case. For now, the pros out weigh the potential cons. But, to each their own.
On a somewhat side note. I use to think similar to you on this subject. But, if the dev community offers a way to back up what the corporate community has failed to provide to us, so be it. If the XDA community has thus far not found any major fault with our Chinese friends software, then I am OK with it. Though, if we find out that this software has been doing potentially bad things, then I would hope that the development community would investigate and destroy them. By the way, if you have the means, keep sensitive data on a separate device. If possible. Maybe one that only connects via WiFi.
