Root is needed!

Credits go to yakk from motofan.ru / Special thanks to Labsin for his involvement and help​

Note: Not all Baseband versions work with this hack, to know if it will work for you, go to settings-> system info and check if baseband version is "EPU93_U_00.59.01". If it is not indicated there, then try installing defybaseband switcher and look at info in the app

If your baseband version is different, you can try to change it to the one that works (nandroid backup first ) by downloading Baseband_change(EPU93_U_00.59.01).zip, and putting it in /sdcard/, and flashing it via recovery.​

Flashing a zip has never been easier

Thanks to labsin, there's an easy flashable.zip that will:

1. Backup your original two files and put them in the folder "simlock_original_files" on your SD card (safety first )
2. Apply a modification to init.mapphone_umts.rc
3. Copy the fixed bp_ptc file

Go into recovery, flash Softunlock_defy_v1.1.zip that fits your baseband version and you're done!
​

!!YOU MUST REBOOT ONCE AFTER THE OPERATION BEFORE CHANGING SIMS!!​

Voila!

Don't forget to reboot phone once!
Only then you can test by rebooting with another simcard

Hit thanks button if i helped you!
Any problems? I'm here to help

Changelog​

v1.3:

• ICS ROMs are now fully supported!

v1.2:

• zip will check if the line to be added already exists, so it doesn't get added more than once

v1.1:

• automated zip that will add a line in mapphone_umts and copy fixed pt_ptc in system

Troubleshooting​

• I have no signal when i put another simcard in my Defy

Have you rebooted at least once BEFORE changing sim cards??​

Try using Defybaseband switcher to select the correct frequencies for your carrier​

Try method below​

• You are still asked the unlock code

- Turn on Airplane Mode
- Run Terminal emulator and type "su" and then "bp_ptc"
- Turn ofr Airplane Mode
​

• Airplane mode won't turn off

Flash the baseband(EPU.0.59..) file in the first post, then play around with your APNs and network settings untill you fix it (see post 308)​

• You are having trouble unlocking a stock ROM

See Post 260​

Proof of success​

Holy mother of Jesus, I could unsimlock my defy+ (plus) . Here is what i did (i think some steps could be ignored but is good to know the entire procedure i've done)

1) Because of a failed CM7 flash, first I flashed a 2.3.5 SBF
2) Flashed quarkx 26-feb nightly for defy+ (baseband EPU93_U_00.60.00)
3) Changed to a proper baseband with defy-baseband-switcher v4.0
3) Changed to baseband EPU_U_00.59.01 following steps mentioned in 1st page
4) Flashed softunlock 1.2 for EPU_U_00.59.01
5) Rebooted (still no sim change till this step)
6) Power off the phone and changed SIM
7) Rebooted
8) Almost had an orgasm

I'll be posting links i used later if somebody ask for them

Thanks to all people directly and indirectly involved (very special thanks to crakeron for his help)

So I guess i use root explorer to put the files where they go?

Correct
A simple copy/paste operation

Ok thanks got it

Update.zip

Made it as an update package so you don't need to use root-explorer...

It should just copy the appropriate files and set the right permissions.

Edit: Now makes a backup to defy_simlock_originals on your sd

Should be that yes. Don't have a locked Defy but should do it.

Can you pls tell it the zip works? Should be the same as pasting so..

 

[thisjustin]

Didn't work with the zip

 

[labsin]

R you on CM7 and witch version? First post also mentions reboot afterwards with good sim and reboot again with other sim.

Did it work the way mentioned in first post?

I admit: I haven't tried this yet, but I did noticed that the OP says to replace init.mapphone_umts.rc to: /system/bootmenu/2nd-init/ and that your patch copies it to: /system/bootmenu/2nd-boot/ folder...

I'm could be wrong on this, but I believe that most people use 2nd-init boot by default (I've only used 2nd-boot while having ICS as dual boot before). But again; I'm just guessing here and could be totally wrong and it might make no difference...

Cheers, and btw, thanks for teaching me how to backup files [with a zip patch]

My OP say's 2nd-init, are you talking about the flashable zip?

Yes, the flashable zip replaces the file in 2 nd-boot directory so I thought that it "might" be why it didn't work for that guy...

Didn't work with the zip

retry with the new zip, there was an adress error in the old one (nothing bad, don't worry)

 

[crakeron]

New flashable zip uploaded. Fixed (changed .../2nd_boot/... to ..../2nd-init/....)

Hello, the file /system/bootmenu/2nd-init/init.mapphone_umts.rc provided did not work for me. It did not detect any SIM card.

So I edited the original file to defy me and I added the line "service bp-ptc /system/bin/bp_ptc" around line 194 (This can change depending on your file) after the line "user root" in the section "# Adb over Network"

After the copy on my smartphone with correct permissions, it worked.

If it can help

Thanks, seems very usefull

Edit: that line is at the right place in the files i gave so you had a different init.mapphone_umts.rc file probably. What ROM are you running?
