Thumbs up [APP] Sim Unlock Free without code

Hello,

I made new free app for unlock Galaxy S and his variants.

Galaxy S Unlock

This app need:
Root + Busybox + Active internet connection.




Not work on Docomo, Docomo have nv_data rev 0.400, International Galaxy S have rev 0.800 and rev 1.500

Tested and worked for Galaxy S sold with android 2.1 (for vibrant and captivate this method is the same of this: http://forum.xda-developers.com/show...&postcount=103 compiled in apk)

Tested and worked on Galaxy S sold with android 2.2 in france all new GS sold with android 2.2 must use step 2 for 2.2.

Link to first test:

http://forum.frandroid.com/topic/389...erche-testeur/

Link to download:

http://perso.numericable.fr/helroz/P...y_S_Unlock.zip

or



For security, save your /efs folder

Step 1 save your /efs folder
Step 2 Unlock your phone in 60 seconds, black screen is normal(get the good step2 for phones sold on 2.1 or 2.2)
Step 3 Built .nv_data.bak (after restart)
And last choice restore /efs folder saved on step 1 if you have any problem.


This is not a final version, test at your risk




Edit 07/02/20011:

Unlock method is changed by only "change lock-bytes" because minority phones have random signal problem and several users delete the backup of efs folder and send me a message for help after

Please send a message for inform me if this method work good for phones sold on 2.2

why the active internet connection ?
just write an apk that will change the lockbit in nv_data.bin and rebuild
it should only need root access

anyway .. a good start

Lockbit is good idea but with normal unlock nv_data have more changes.

With internet connection, i download my generic unlocked nv_data and i built a real unlocked nv_data.

I have retourn of SGS unlock pro and new nv_data on phone sold with froyo, just Lockbit change make problem with 3g and call.

And my unlocked nv_data are in zip, just 15kb...

nice idea, I'm glad somebody develops an app for this issue!

I am currently running 2.2.1, any experience with this FW?

I can send you the proper nv_data.bin template file File attached .. now you can include it in your apk and like this, your program will have to extract the imei from original nv_data.bin and after, insert it into the template and then replace it in efs (also deleting the md5 in the process).

One click job and still no internet connection

FULLY Tested on 2.2 and 2.2.1 (stock/factory 2.2 / 2.2.1 and also 2.2 / 2.2.1 upgraded from 2.1)

PS: Add an input box so one can chose a new NCK and Freeze code for later re-locking by code for warranty *7465625*638*# and like this, they won't need any app to re-lock it since they have the code the phone accepts

I don't need you for have good nv_data for unlock.

I unlock I9000 since september and my method is reference of all other.

My choice for download is just a choice.

And my 2 unlocked nv_data was made with a normal unlock method. After i change just a imei and product code.

And for relock for garanty, just reinsert efs save of step1 and it's good.
