Hi, I recently bought a used Sprint Tab 3. It's a data sim card version but I only plan to use it for wifi. Previous owner did a factory reset. Everything works fine, I rooted it to get rid of bloatware, no sim notifications, sprint crap etc. However, when I go to settings -> about device -> status, it shows a user name, eg. "[email protected]" plus a phone number, MIN, PRL, etc. Tablet shows as connected to 3G network even though there's no sim card. If I enable airplane mode and reboot, all the fields show up as unknown and mobile network as disconnected, however the username remains.
I believe that info is from the previous owner, but where is it stored? I'm guessing the tab is getting it from the network even though there is no sim card in it to authenticate it which doesn't make sense. Removing all Sprint related stuff does nothing. I tried wiping the whole tablet and flashing a beta CarbonRom that was in the forums and the info still shows up in the about device status. I flashed back to stock rooted. Only difference is that android 4.2.2 has the username option while kit kat doesn't. Since I had made a complete backup of the tablet, I wiped the efs partition just for the heck of it and rebooted. Interestingly enough it removed the Sprint boot animations and replaced them with stock Samsung ones. Folder was recreated by android. Everything else is still the same. I was expecting the tab not to connect to anything anymore but I guess not. For all the doom and gloom that is said about wiping the efs partition, I was a bit surprised that it didn't absolutely nothing. There wasn't even a nv_data.bin file in it (although my S3 is also missing this file for some reason too.)
Any suggestions? I was thinking about trying to contact the person that sold it me, maybe he hasn't taken the tab off his account yet or something. If anything I can just keep airplane mode on with wifi enabled, still wondering how the tab is getting that info. I'd rather not have anything of the previous owner on it.

I have a brand new issue that, for the first time, I haven't been able to resolve from existing posts on the forum.
When Cyanogen nightly build 92 first came out I loaded it on my phone and everything had been working flawless. Yesterday I swapped my SD card for a another one, something I do with regularity and have never had trouble. Afterward, the phone wouldn't boot.(black screen) I swapped back and still nothing. I removed the SD card entirely and installed another SIM from my G1. Although, it would not boot into the phone I was finally able to boot into CW, so I reset all caches, reformatted boot, system and data. Reinstalled build 92. About halfway through the reinstall the phone suddenly rebooted. I started over again, wiping cache, reformatting and reinstalling to build 92. (I double checked md5sum just in case the file was corrupt) This time it installed perfectly and I was able to reboot the phone back to what appeared to be normal.
Now everything appears to work fine except for one very serious flaw. I can no longer connect to an APN. I can search networks and see them but when I select one it says cannot register on network. If I connect to WiFi the "WiFi calling feature works fine and all seems normal. I did a little research and was told to check my IMEI. Sure enough it is 111111111111111 which is obviously invalid. I have no idea if the Invalid IMEI is a symptom of another problem or the cause.
Just for grins, I borrowed a friends AT&T Sim to see what would happen.( I recently updated to the gfree .05 for full unlock) There was no difference except of course, AT&T doesn't support T-mobile's WiFi Calling.
So here is where I stand so far:
Original SIM is fried so have a new one
Invalid IMEI but I have my original logged
WiFi Calling allows me to operate the phone normally but I can't go anywhere this way.
I have all of my CW backups and have tried them to no avail.
The swap of my SD Card is normal for me. When I travel I use an encrypted card for all of my data. (A slightly paranoid industry, {Corporate Intelligence} but hey, I get to use calling encryption)
I never store apps on my SD card and always select Internal as my installation location, not that it should cause a problem anyway.
I have been actively using and updating my phones since Jesus Freke started on 1.5 on the G1, so I am not afraid to get creative.
Any suggestion or direction at this point would be greatly appreciated.
Hello.
My HTC Touch Pro 2 encountered the following problem:
Additional to the PIN (for SIM-Card) I have also set a 4 digit PIN to lock the device, which is activated automatically after 5 minutes.
After accidentally deep discharge of the battery (forgot my phone in the drawer of my desk for over a week) and loading the battery afterwards, the phone refuses to unlock the device. The inputting device lock code, which is 100% correct, does not work anymore- no matter whether I type it on the touch screen or keyboard.
Even after several soft reset - not change. The PIN (for SIM-Card) works but the device-Lock PIN does not. No possibility to unlocked the device – it tells me always “entered code is wrong”. Even after connecting to a PC, the computer does not recognize the phone - so I cannot even read out the data of the phone via a computer.
On the phone are important data, photos, entries that I will not delete!
HTC has got - as usual – no idea of their own devices and the German support on the phone told me that I should buy myself a new cell phone - very helpful!
A hardware reset / reset of the device, I do not want to do otherwise the data all are gone.
Is there a way to circumvent/ bypass the device lock and hack the data in some way out my phone?
The emergency plan, which I do not want to try by now, would be a hardware reset and subsequent data recovery using the software "File Scavenger ®" This works very, very good with defective USB sticks and accidentally deleted computer hard disc drives (deleted system volume information etc.) . Unfortunately I have no idea what kind of memory, the HTC Touch Pro 2 uses (it's been no SD card inserted in the device).
And I do not know how the phone reset works - simple device reset witch clears memory only (which would not be that serious) or if the entire memory will be overwritten (which would be fatal).
Maybe someone has a solution and can help me, how to get my data out of my cell phone. Thank you!
If you have the data on the SD card, why worry? Photos, music, etc should all be on the SD card, not the phone itself.
Either way, I doubt you'll be able to recovery anything. Good luck.
If your data is on the sd card/sim card then I would pop it out and do a hard reset on the phone. Put it back in and hope for the best after the reset.
If your data is on the phone you are screwed. When you do a hard reset it will do lots of writing to the nand memory, and overwrite anything you might try to scan for data recovery.
I have never heard of anyone finding a way to get into the data on these phones when the pin didn't work. It is also the reason I never used that feature.

OP mentioned that he does not have a SD card inserted into the device. I think that is why he is so concerned!
Any updates there OP?
Hey guys,
I recently updated to the latest CM10.1 (d2att) from get.cm. I also updated to the latest GApps. Before installing, I wiped cache and dalvik cache. I also performed a factory reset.
That said, after I booted to the system, my mobile data and WiFi did not work. I rebooted the phone and still nothing. I reset my APNs and nothing. I searched far and wide and people are saying the d2vzw (Verizon GS3) is having this issue, but the d2att users seem to be having no issue at all.
I turned on Airplane mode and rebooted the device. I then disabled Airplane mode and WiFi/Mobile Data kicked on and I was good to go.. however when I rebooted my phone again to test, it was disabled. I seem to have to do this each and every time if I want WiFi/Mobile Data.
Another concern is USB connectivity.... My PC sees my phone, however the sdcard and internal storage drives seem to be swapped. What I mean by this is my PC is displaying the contents of the phone's internal storage as 'sdcard' and vice versa. If I remove the MicroSD card from the phone, my computer shows an empty folder for Internal Storage. (however it shows that there is 5gb of space used on the drive). Copying and Transferring is disabled.
When I tried the 12/17 nightly, I had usb access because I flashed back with ease, however now that I have the 12/18 I have lost access to my TWRP backups and have to reflash 10.0.0 in order to regain access and then flash my backups.
Is anyone else experiencing anything similar, and if so is there a fix?
Thanks,
Ryan

Thank you so much for the link and quick replies guys! I am very sorry, I searched using forums and google (actually since 2pm this afternoon ET, and even checked the cyanogenmod IRC channel, but no one stated they had issues.)
Glad to know they are being addressed and I'll follow that thread going forward!
Have a great night!
so here is my problem.
i have a samsung note 2 (N7100) with 16 gb internal memory. I didn't paid much attention to the internal memory space, and had tons of data on it. And the phone reached a stage, where the internal memory (16gb) got entirely full. so, the phone got off automatically maybe due to unavailability of the space required to run the phone and apps.
I didn't had much idea about it, but 2 or 3 days before my phone went off, i had checked my internal memory and it was on the verge of getting full almost, i had this thing in my mind that when it will get almost full, a message will pop up on screen saying "your memory is full, please delete files." But, in vain.
Now the thing is, the phone won't start up, when you press the power on button, it will show the screen with samsung logo but won't go through. the logo will stay or the phone will automatically turn off. I am not much of a tech guy. I tried going to local repairing shops, but they all had this one thing, we can start your phone but we can not pull out the data and consider your data as gone. Data is highly important for me. I do not have any issues if the phone does not start up, but i want to extract my data anyhow, as it has my personal data (media and documents) of the last entire year, i know when i knew that data was so important than i should have backed that up from time to time. But, i do not have any backup.
i had never installled any custom os or no nothing about rooting my phone. the phone was running android 4.2.2 and i used apps like snapchat, whatsapp, bbm , document reader , facebook and few games.
i started searching out on the net for my problem, as i can not handover my device to any local or repairing guy, because they can not get me my data back for sure. than i found this thing, you can go to bootmenu than scrolldown to "clear cache memory" and maybe that could release a bit of space on the phone and somehow get my phone started and get me my data back. To get to the boot menu,
Boot Into Recovery Mode on Samsung Galaxy Note 2
Turn off your Samsung Galaxy Note 2 device.
With your device turned off, press the Volume Up, Power button and Home Button at the same time, for a couple of seconds.
When you see the recovery mode displayed on the screen, release the buttons.
i exactly did the same thing as mentioned above, but did not found any recovery screen rather found screen warning me about custom os or custom rom installation and other option read start phone normally. on selecting the first option and continuing "that i understand the risks of installing custom rom'" a screen will appear saying downloading and nothing will happen. and if i say second option the phone will start, and the samsung screen will come up and it won't go through.
the bottom line: my phone won't start up. And i won't be able to pop my data.
i had tried factory reset via boot menu earlier in the past in samsung galaxy y and y duos , there i did saw factory reset, cache wipe , ackup and other expected recovery screen. I know what the recovery screen looks like but in this case i can not get through as some odin something screen will appear instead of recovery screen. I won't find normal boot options but this two stubborn options as mentioned above here.
I don't know what to do . i would be highly grateful if anyone from here can help me out. and i already went through several threads in the forum, but none of the thread exactly matched my problem.
i also had this one idea that if i can remove the memory ic from the ciruit board of the phone and can get it fixed on other note 2's memory than maybe i could get my memory on that device and can recover. I know its dumb to think so and such a thing is not possible as everything on the circuit board is heavily linked to the board and we can not remove the memory ic. I can not get my files via hardware manipulation i know.
also, i have learned that flashing or re-installing the os, would start up my phone, but i would loose all my data and that's what i do not want. There are recovery apps such as recuva, which can recover your data, but that's still like taking a chance and is risky. and may be internal memory data can not be recovered.
Every android guy i knew all said the same thing that there is no way to get the data back even the android geeks whom i knew said the same thing. i am helpless.
I need media and document files mainly and importantly.
I just want someone from here to be a angel and push away my problem and help me out.
i do not have anything such as developer mode on in my phone, as i have already said that i am not much of a tech guy. I am a normal user without much knowledge of how to fix , root or any other thing.
please help me out.
Thanks for your valuable time in much advance.
The only hope is this thread. Be my saviour.
First off, thank you for reading this.
A couple of weeks ago I went to use my phone. I typed my security code into unlock the screen and the phone froze. After a few minutes, the phone rebooted, and took a long time to boot, and came back to the "Welcome to Verizon" prompts you get when first turning on a brand new phone; it appears the phone went thru a factory reset! After getting thru the prompts, I found that ALL data on the phone and the external SD card was erased.
I tried to recover the files from the SD card by connecting the card to my Windows machine and running and my trusty recovery tools (which have always worked in the past on formatted drives). All the tools I normally use failed to find any files. So, I bought Wondershare Dr. Fone - and it actually worked on the SD card. It's not the greatest tool, but it was at least able to recover my media files. When Dr Fone attempted to scan the phone's memory it failed because it was not able to root the phone. After some reading, I see that it is not possible to root a Note 4 (Verizon). However, it appears there might be a temp root possible. Can anyone give me some general direction on how I can recover data from the phone's memory (I have more media that plus some other app-related files)? Will a temp-root allow Dr Fone to scan?
Thanks in advance.

From my experience, you could get help from professional app
Since your phone is wiped, you could apply to Samsung Data Recovery app. It works better if your phone is rooted. good luck.
