Cannot Unlock new Tab

Just got a new Tab from a carrier shop here in Kuwait with some, let's just say, undesirable applications preinstalled which I would like to get rid off. Read all (well most of the posts) but getting nowhere.
Upgraded to new firmware through KIES.
downloaded Z4ROOT and rooted succesfully (or at least that,s what the app is telling).
Tried to copy the nv_data.bin file to my sd card - cannot be done
Tried to open nv_data.bin in HEXEDITOR - no can do
Tried to delete application - nope
So some help is obviously needed here if anyone is kind.
Best regards

You did install busybox, did you?
Which firmware? Post what you are doing on the adb shell. Be specific or we can't help you.

You're right should be more specific.
Well I did not install busybox (no idea what it is for) and
Firmware version is 2.2
Baseband version P1000JXJK2
Kernel version 2.6.32.9 [email protected]#1
Build No FROYO.JPJK2
Hope this clears it.

Busybox gives you most shell commands (including, but not limited to, cp).

Thanks.
Installed BUSYBOX and copied nv_data.bin file to sd card for modification as per How to carrier/SIM unlock the Galaxy Tab topic from 17/11 but the address 0x181469 could not be found.
Also tried to uninstall the preinstalled apps - no success

need z4 unroot it
busybox
root explorer

Z4 unroot, DONE
BUSYBOX installed DONE
ROOT EXPLORER installed DONE

So

totaly worked for unlocking the SIM/carrier. Very easy and no problems encountered. Inserted a different SIM and made a call. Perfect. Thank you for all the work that made this possible.
However it still does not let me delete the APPs that came preinstalled with the Tab.
I am guessing this is something to do with the Kernel version 2.6.32.9 [email protected]#1. How can this be undone (another guess is flashing the ROM but i have no idea what it involves so back to the reading and learning)?
If somebody has a simple to follow guide and resolution to this please let me know the thread. Thanks

Have you mounted /system as r/w in Root Explorer?
Regards,
Dave

Dave, to advanced for me. How do i do that?

Just an update.
Managed to successfully flash the tab to the european version using guide from
[HOW-TO] Flash your at&t Tab to make calls + 1900+850 WCDMA - UPDATED
thank you it worked fine and i achieved what i was looking for: no more undesirable apps.
But, i lost the 3g and cannot get it back using the same guide as above.
With my limited knowledge of the whole thing I am guessing that this is to do with the modem.bin file. Will try to download an arabic version of firmware, extract it and try to use the modem file and see if it will work. will post an update just in case anybody is interested,
regards

I found it rather embarassing posting replys to my own thread all the time but I feel it might help somebody so what the hell!!
I finally got my 3G working on the Tab. A silly thing really: APN (Access Point Name) was deleted during flash and by adding and activating the APN i got my 3G restored.
Anyway, thank you guys for all the replies and help. Really good forum with a lot of useful stuff.
Regards

Guide for unlocking fastboot and flashing custom roms.
http://androidforums.com/optimus-gt...nogenmod-7-android-2-3-4-avaliable-gt540.html
My app root toolbox will flash a recovery image, all download links in my signature.
For root access use z4root. Don't update to 2.1 because z4root doesn't work on some versions of it.

Also have a look here before you change roms/unlock fastboot

Hey there
Nice to see you're still on 1.6 , We really need your help right now!
http://forum.xda-developers.com/showthread.php?t=1123968
If you haven't already rooted , Follow these steps :
1. Download http://bit.ly/9wAKC5 and transfer to phones SD Card
2. Download Astro File Manager in Market (Or any other file manager)
3. Open the file manager and locate the application you downloaded
4. Click on the File and Install the Universal Androot .apk
5. Run Universal Androot and select Superuser for 2.0 - 2.2
6. Click 'Go Root'
7. Follow any restart prompts
8. Go back into market and download Terminal Emulator
9. Follow the instructions from the CODE box on http://forum.xda-developers.com/showthread.php?t=1123968
10. The files will be created in the backup1.6 folder on the SD
11. Using a computer, .ZIP these files and upload them to the filesharing site of your choice
12. Share the link to us
13. Be very proud of yourself, you've helped us all
Then after , I would install 2.1 using LG Software Updater (Easiest Method)
But EVERYTHING is deleted , Including contacts and SMS when doing so. To backup contacts , click Contacts , Press Menu and press Export then Export to SD
To backup SMS I recommend SMS Backup and Restore from Market.
Hope I helped Jamie

haha okei, i'll try to do that so i can give you a recovery imagine of 1.6
and you told me to upload to official 2.1 android through lg site,, i am known that 2.1 is just, mmm , as 1.6 XD i mean, you have problems to install things in the sd, and many apks does not work, and the flash is dead x.x haha
but well, i'll do that first before upgrading to another version!

[Arc/S]Update to 4.0.4 Rooted **Updated**

Hi All There is One grate tutorial out there to accomplish this goal
so i thought id make it a bit more clear for all.
original post by: OverLo4d
Okay so most of the text here is by OverLo4d , I have just added more info to each part to clear it up.
==
my text will be in here.
==
Ok here we go....
after i used buzzinkeegs's tutorial to root my Arc s i thought to put the 562 kernel in the 431 FTF, so the only thing you need to do is rooting with OneClick root exploit for the 4.0.3!
1) flash the ready to root 4.0.4
===
To Flash the required ftf files you will need flashtool 8
there are many forums around to help you with this.
===
for the Arc s:
http://uploaded.to/file/14aaw2yg
http://www.filefactory.com/file/3y2i...dy_to_root.rar
for the Arc:
http://uploaded.to/file/fhx78bgu
http://www.filefactory.com/file/1jir...dy_to_root.rar
===
Once flash tool has finished flashing the ready to root ftf
it will automatically restart the device if not disconnect the device
and boot it up.
===
note: you might get errors after the reboot, don't worry, this is normal and step 3 will fix that.
===
Once the device has booted choose language and skip everything else.
go into settings and turn on usb debug and unknown sources.
Connect the device to the pc and root with this tool below
The setting will only be required if you choose to wipe data when flashing the first ftf
otherwise just boot device and connect.
===
2) root your Arc/s with this:
http://forum.xda-developers.com/show....php?t=1601038
===
When the tool exits and finishes, disconnect and power off the
device
===
3) flash the 4.0.4 kernel
===
Again Flash the kernel only ftf file with flash tool
===
Arc kernel only:
http://uploaded.to/file/ivzlpk6e
http://www.filefactory.com/file/1e16...ernel_only.ftf
Arc s kernel only:
http://uploaded.to/file/tfs9vxs8
http://www.filefactory.com/file/1dyq...ernel_only.ftf
===
Again when flashtool reboots the device or you do manually
you will have a rooted 4.0.4 device.
===
that's all, you have a complete 4.0.4 rooted Arc/s!
only three steps, Flash Root Flash.
buzzinkeegs's tutorial:
http://forum.xda-developers.com/show....php?t=1683189
===
I have no experience with the Pro so i have removed that part from
this post. please view original post for instructions on the PRO
===
============
***UPDATE***
For people having issues uninstalling system/vendor apps after the root
this is because most app removers do not support the new Vendor location where
apps are stored.
The only one i have found as of yet that works is SystemCleanup
this can be downloaded from the market.
=============
=============
Thank you all Hopefully that helps out
with this simple but error full install.
enjoy.
all the credit to OverLo4d

i noticed only one thing that can be problematic, what you said there should happen only if you wipe user data. some people (the noobs) might get confused. if you could mention that it would be great

Im glad you like it. i have also updated the first post to include that and also
an extra bit to explain system/vendor app removal at the bottom.

Yes please do read all posts that are related to this before stating q fake root. Also I stated why this happens with TB and how to remove the apps with the updated app. I would assume TB will update soon to fix this issue.
Also the root is confirmed because I have added custom ui tweets witch requires a root explorer(esfile mgr)
And root to change system files.

[Q] Back to 4.2.2 ? Guide doesn't work!

Hello
I've got a problem to flash back my LG G2 to 4.2.2 (from original 4.4.2)
I've tried both ways of this guide ( http://forum.xda-developers.com/showthread.php?t=2432476) but my access was both times denied ( 1. time running Automatic Offline Procedure.vbs 2. time saving the hosts file) by windows ( I'm running windows 8.1 )
What should I do now? (Of course I'm the Admin on my pc )
I would appreciate every help and tip.
Thank you very much in advance for your answers,

reboot computer.
go to hostfile, manually edit the file. dont save as text but as all files.
follow tutorial go back to root. check firewall to allow https program, and virusscan to allow https.
boom done.
reboot, change hostfile back. reboot and done.

Changing MAC ID

For permanent change, go here.
For temporary change, go here.
Temporary change is easy to do, but MAC id will change once you switch wifi on/off or reboot.
Permanent change, might work or not depending on the kernel, and is surely a complicated process.
So the choice is yours

use Pry-fy

Detailed Procedure which i found working on my device ( Lenovo A 6000 + )after lots of attempts. Hope it helps someone.
1. Take backup of all data.( Incase of data loss, which i haven't experieced with expeerience of araound 20 times rooting)
2. Root your phone using kingoroot (via PC ) (my preference --you can root any way you want )
3. Check root sataus using root checker app (Its in playstore )
4. Make sure you have Super User (App which guarantees root access) .Its is installed automatically when rooted via Kingoroot software.(Or install it from playstore)
6. Install ESFile Explorer from playstore (again its my preference,you can use any root explorer )
7. Enable root explorer option in ES File Explorer(Grant root access when asked)
8. Directory to change mac id
Device -> sys -> devices -> soc.0 -> a000000.qcom,wcnss -> wcnss_mac_addr.
9.Open the file in ES Note Editor and change the mac to whichever you want.
10. Switch on aeroplane mode and off it.(Then only mac id changes).
Note:-
1. Mac ID is reset when resetted .(Switching wifi on and off doesn't affect)
2. The above procedure works in stock ROM (lollipop and kitkat )
Plz reply if any probs...I figured it out after too many attempts as i am quite new to these things.
