[Completed] Question about CWM and Galaxy Tab Data Loss - XDA Assist

Hello there! I'm new here, lot of experience doing bench-tech repairs, phones, computers, laptops, consoles, web development and graphic design. But 0 experience rooting android and installing custom recovery. I am here because I have a Galaxy Tab 4 (SM-T230NU) that is locked with a pass-code that I don't know. I could do a factory reset but I don't want to lose data. I read another post about flashing a zip file through recovery might help me remove the pass-code. However this device is completely stock, not rooted, no usb debugging, and no custom recovery.
So my question is, can i install ClockworkMod on Galaxy Tab 4 (SM-T230NU) without losing any data? I really only want it so I can remove the pass-code, if there is data loss I may be better off doing a factory reset. (please note, it is not backed or synched to a google account)
Any pointers in the right direction will be most helpful. Thank you XDA!

PLEASE HELP!
Anyone? Please?
Guys I need help!
I can not help you with your tablet, but what I can recommend is posting this in the Q&A section. You are more likely to get a response there.
heres what I used
I used a file called tabatronics which is a Verizon uberoid except no configuration settings just extract to card and power on worked like a charm including touch screen which is what I kept having issues I think I uploaded this file if not let me know. I have two of these called a boss 7in tablet I got on base but took almost 2 months to find a file that worked.
There are two files u extract one is a command the other a folder with the system remove these from your card.or zip when done or will install on each boot and took lose everything also made mine alot faster hope this helps.

[Q] Lost all networks after nandroid backup?

Hey guys,
I was running a stock 4.0.4 GSM, IMM76D and wanted to try out some new ROMs. I did a nandroid backup beforehand and tried flashing Pixel ROM & Slim ICS. I wiped data, cache, dalvik, system, etc. then tried the new ROMs. Something went wrong and I applied the nandroid backup from ClockworkMod.
After the backup, I seem to have lost all network signals. This is what I have:

}
My Baseband version is "unknown"
I've read a good deal of topics with related problems, but failed to find a solution for my situation. My last resort is flashing the stock 4.0.4 again, but I'd really appreciate it if anyone could help.
seems to me that your efs folder got corrupted and u lost your imei. Did u made a backup of it before starting the flashing spree?
If not, i have bad news for you, you may have to end up sending your Nexus for repair.
If you can't restore your Nexus with factory images as described in the other thread where you posted this morning, take a look here:

Thanks for the replies, guys!
ezio84, I tried EFS Pro. This is what I got:
It says everything should be fine, but still: http://i.imgur.com/oLw1f.png ..no signal. I pressed "Repair NV Data" button and hoped that it might help me. I didn't find any additional instructions on how to use the program in the original thread you linked me to, so I assume this might not be the right way to approach this problem.
I'll try your advice in the other thread on flashing the factory image, after installing the new usb driver.
Again, thank you for your replies!
I did it! I have the network signal again.
I updated the SDK package (which doesn't have anything to do with the solution, but still), and then I flashed a new radio from this thread: http://forum.xda-developers.com/showthread.php?t=1116884 (KB1 did the job for me)
Pretty simple, but I had to read through something like 20 threads, +500 comments to get to the right answer.
Again, guys, thank you for your help!
Good! Happy for you ;D

What's your phone model? Not Nexus? The radio you mentioned was not for Nexus. Is it OK for Nexus? My Nexus lost baseband and IMEI too. I have not found out how this happened. Maybe nandroid as you said. I used cmw recovery made a backup too... And then, no network signal

[Q] Unbricked to newest 4.1.1 release, now unrooted on SCH-i535 Verizon

I unbricked my phone using this guide: http://forum.xda-developers.com/showthread.php?t=1762709
It gave me a choice of factory stock roms to install during the recovery:
Step 2: Download one of the Factory Stock roms below to your pc:
VRBLJ1 4.1.1- http://www.myandroidfiles.com/open1y..._WIPE).tar.md5 (This is a Verizon Leak, but damn its smooth!)

I opted for the 4.1.1 newly leaked version. This is now my "About Device" pic:

So, now my phone appears as if it came with JB out of the box. I have no root and it's running smooth as butter! Love, love, love it.
Can someone describe the current state of my phone? I know that sounds like a stupid question -- and it likely is -- but I can't understand how I have JB yet not rooted.
And two issues I need help resolving:
1) USB connection to my Mac. I used to have some issues on out-of-the-box ICS but Android File Transfer app solved those issues. Now that doesn't even pick up the connection.
2) Wifi Tethering. If there is a rooted solution for my setup, I need to if root guides are safe to follow with the current state of my phone.
-Obviously a newb... but lots of love and respect to the developers out here who make life so much easier for all of us normal folk.
I'm running 4.1.1 too and love it. I'm not rooted either or unlocked.
Android file transfer no longer works with the GS3. I have a Mac too and I'm not happy that I can't transfer files easily.
A lot of people on these forums will tell you about alternatives but honestly, they all suck. Android file transfer was amazing. Only thing we can hope for is a new version from Google...

i guess i can use bluetooth for the one off file transfers. But if down the road I need to get in there for more heavy lifting I'll need to fix that.
Most importantly though - no wifi tether on 4.1.1 for Verzon gs3's ?
I got the other issues fixed except google search is not returning a voice response.
Make sure to backup internal sd and ONLY use the full wipe versions in odin.

K3 Non note question. (K30w)

By mistake I ordered a K3, not the note version.
From what I came to know is that this device is intended for the Asian market only.
The phone has really bad software, and after a bit of searching on this forum and Google I have yet to find an answer to the following questions:
Is it possible to install another rom on this phone?
Are there any out there?
Is it the same phone as the A6000 (or does it accept the same roms)?
I have rooted/installed firware on phones before.
I am sorry if I overlooked any relevant information.
Nobody?
I managed to get a custom rom working, i'll make a post in this topic to help others out.

}
On your current (stock) rom:
- Download all the software needed: https://ufile.io/a8497
- Enable USB Debugging after connecting it to your pc.
- Download TWRP for A6000 (unzip on your pc)
- Download K30-W_MIUI6_5.1.23_liuxingghost-0501251930-RUS-UK-MIUI.SU_v2.zip and place it on your phone's SD-card!
- Open "Boot-TWRP_A6000.bat"
- Phone will reboot into recovery
- Wipe > Advanced wipe
- Select first 4 options and wipe
- Go back to the main menu of TWRP and "install zip"
- Select the rom, and install.
After the rom is installed, the boot will take LONG to the point you will think the flashing has failed. Don't worry, it will boot, this is only the first time.
If it asks to update, don't it will fail.
OPTIONAL: After rom booted, put Google_installer.apk on your SD and run it from the file explorer, install ALL parts of the software to get play store working.
OPTIONAL: Install galleryGoogle.apk to get the standard android gallery, the one provided sucks imo.
The rom is only in chinese/enlish, but the standard software is so crappy and bloated, that this is a hell of a lot better.
After a bit of configuring I managed to get it all to proper English, and got play store working. The phone runs smoothly, and everything is working fine (even 4G).
ROM VERSION: 4.4.4 KUT84P
MIUI version 5.1.23 | Beta
I am not responsible for bricking your phone!
If anyone could provide me with a better rom I would be very happy, although this one is working fine for the moment.

You may want to read through this thread, the ROM linked above is in post #25(message#25) in the thread linked below. There are also many different ROMs there that you might can use with a little bit of work to set it up.
