No idea how to use I can't find any proper help which actually explains how this works.. I know it needs this busybox thing and a root thing so I downloaded something else on here when i searched those names.... The English blog "help" no longer seems to work. So may be amazing but needs a very simple explanation for most people to be able to use. The french one translated was no help to me either.
Did work Did have 4.0.1 but updated to 4.2.2 and lost it. I run step 1 and 2 with no signal so reboot as instructed and its still locked up with code screen still in place. Tryd doing step 3 before reboot after reboot the lot still not working. Any ideas would be nice as its a great tool hence the 4* rating
great app!! tried [root] Galaxy S2 SIM Unlock first - couldn't find my unlock code....so tried to extract nv_data to do a hex decode to get the unlock code....too much trouble. found this and ran steps 1 and 2, then restarted and BOOM!!!! unlocked. magic. thanks xxx running 2.3.3 GB on SGS2 from TMO UK, now on prepaid TMO USA :D *happy girl*
Success Works for new galaxy s2, ICS version 4.0.3. Make sure your phone is rooted (when choosing kernel to flash, out of the many available, choose the one that matches the PDA code in your phone info. I.e. for mine i had version lpd, so i Googled xxlpd/xwlpd root sgs 2. Follow instructions on good tutorial. Busy box.should.be.opened once downloaded and installed from within the app.
This app successfully unlocked my Galaxy S3 (gt-i9300), just after I upgraded it to run Android 5.1 (yes you can!). It took a few minutes before it worked, and the screen did indeed go black, but you could use other apps on the phone whilst it unlocked it.
Unlocked my Galaxy S2 easy !! I have a Samsung Galaxy s2 which was locked to T-Mobile. I tried an app called Galaxy s2 unlock which took about 45 mins and didn't work! This app did it in a minute and didn't even require the phone to restart !!! My text messages just started to come through :) Very impressed Thank you. Would recomend to anyone.
New firmwares have a new protection, at restart the phone is locked, i work on a new program for unlock the phone at all start automatically. At this time, you must unlock at all reboot.
3.05: Minor update for non working galaxy s
Changed the reboot method by only restart rild (thanx to Supercurio for the trick)
If you have any problem, click on restore saved efs folder.
Please Add comment if all work good or not, i don't have any I9300 for test on it.
