[Galaxy S III General] 0blivious:
For people that don't get the md5 from the log file, I've been able to unlock with the following steps.

- firmware to 4.0.4

- root phone

- install root browser (I keep the apk on an ext sd and install via the cmw tool included in the cf-root 6.4)

- copy .nv_state and nv_data.bin from efs folder (keep an original copy on computer)

- edit .nv_state from 0x31 or 1 to 0x30 or 0

- edit nv_data.bin address 00181460 position 9 from 01 to 00

- [reboot]

- *#7465625#

- check Network Lock is [OFF]

- [congrats phone is unlocked now!]

this doesn't work on 4.1.2, so upgrading from this succesful unlock is a no-no

there should be a desktop tool somewhere that can generate the same android type md5 so we only need to edit the nv_data.bin and nv_data.bin.md5

Hi,

I try to unlock my Samsung Galaxy S3 with this steps, but not works :(

I have Android JB 4.1.2.

My S3 are rooted, When I use GalaxySim Unlocked I see:

"Device model: GT-I9300"

"Block sim status: UNLOCK"

Then... Why my simcard not works ??... I put this simcard in other phone and works fine... then... what happend :S ?

Somebody can help me please ?

Hi again...

When I bought this phone, have root (Superuser), but... I flash the phone to remove the root with stock rom (same installed rom)... but... "surprise", my simcard not works :(

I try to root again the phone... and install "GalaxySim Unlock" but this app shows: "UNLOCKED"... then... I dont understand why my simcard not works... I try with other simcard and not works too :(

I check this things:

- When I press *#06# I see IMEI: 4205*******7987 / 04 (I have a screenshot of this before the flash with stock rom)

- When I extract the battery and see in back of phone: 3584*********5025

When I bought this phone, have german language and this info:

AP: I9300XXELL5

CP: I9300BUELK1

CSC: I9300VFGELL1

Hello again,

I took my phone to a technician, he does connect my phone to PC through an application and another apparatus and changed the IMEI to release it.

Then, he flash again the phone, and missed the unlock.

The technician went back to change the IMEI, did factory reset and everything OK.

Now what I want to know is, if I make a backup of the folder or partition "/ efs" I can flash again, apply root and replace the folder "/efs" which I was save to preserve my unlock?

Thanks.

Sorry to be a div, unfortunately I have the same problem.

When you say compute md5 hash like this, could you explain how to carry out the computing ie. What program to use or more specific steps

appreciated
[Galaxy S III General] .NetRolller 3D:
Use the "md5sum" command, as I have written. That line is not a general description of what you have to do - it is the exact command for generating the md5. Run it using adb shell or Android Terminal Emulator (you may have to install Busybox first).

4.2.2

Hello.

i have a gt-i9300 4.2.2 from Vodafone PT.

i was getting "cracking detected" then i tried using the nv_core files from efs.zip and the nv.log didnt say anything after i reboot the phone.

but galaxsim unlock says i im still locked and i have inconsistent nv data.

what i did :

changed the nv data in the 181460 address, generated a md5 with the terminal emulator ,

copied those 2 files and changed their permitions (if i rebooted in this step i would get cracking detected);

then i copied both files from efs.zip (the nv core hidden files)

rebooted.

still locked i guess, dont have yet a sim to test it though. galaxsim says im locked, have inconsistent nv data and have a risk to loose my IMEI, it also suggests me to restore efs by now. (yes i have a backup of it)

thanks in advance guys

EDIT:

i ended up downgrading to stock 4.1.1 and happened exactly the same, but the phone is unlocked!
[Galaxy S III General] .NetRolller 3D:
If you are having problems finding the MD5 in the log:

Calculate md5 by running this command on a linux machine:

No need to downgrade to 4.1.1.

Does this work on stock 4.3? Thanks in advance.

If it does, how can I get the md5 checksum with BusyBox?

Thanks.
[Galaxy S III General] .NetRolller 3D:
I cannot personally check, but it should work.

The MD5 command is the same that I posted earlier. Only works if your version of busybox includes md5sum - otherwise, find a Linux PC to compute md5.

[Galaxy S III General] sillybun:
little success story on how i came to circumvent the "cracking detected" issue:

i have a gt-i9300 baseband version XXDLID. i flashed TWRP on it, then LineageOS 14.1, which uses android 7.1.2 - i also rooted it while doing that. first i tried unlocking via the secret code to the service menu, but the "NETWORK LOCK" submenu didnt exist (even when i downgraded to 4.0.1 or whatever it was). according to GalaxSim Unlock i have efs v1.

!!!BACKUP YOUR EFS BEFORE DOING ANY OF THE FOLLOWING!!!

so next i tried the procedure from the first post in this thread, combined with user ".NetRoller 3D"`s helpful suggestion to get the correct md5sum via

(cat nv_data.bin; echo -n Samsung_Android_RIL) | md5sum

problem was, on reboot my hexedit changes to nv_data.bin were undone, and nv.log had the nasty "cracking detected" line. desperate as i was, i went out on a limb and modified the .nv_core.bak, .nv_core.bak.md5, .nv_data.bak and .nv_data.md5 as well.

both .nv_data files i simply copied over from the nv_data files i had created as described here in the original post (and using ".NetRoller 3D"`s command). in the nv_core.bak, i searched for "01ff 0000 0000 0517", since that was the string i altered in nv_data as well. and indeed did i find that section (at a different adress though, so the numbers before that didn't match)! so i changed it to "00ff 0000 0000 0517", saved, calculated md5 via

(cat .nv_core.bak; echo -n Samsung_Android_RIL) | md5sum

, put that in .nv_core.bak.md5, changed permissions and owner on all files i altered, and the rebooted. and BAM, simlock gone! after one week of tinkering and immense frustration, i am now quite euphoric :D

bloody leeches from the network wanted 40€, even though the phone was paid off during the contract - well suck on me having it unlocked for 0€, you twats!

thanks a whole bunch & kudos to vinokirk and to .NetRoller 3D!

ADDED BONUS COMMENT:

btw, if you have adb on your PC and a rooted phone, then you don't need the RootExplorer. you may copy from phone to PC by executing on your PC

adb root

adb pull /efs/nv_data.bin /somewhere/on/my/PC/

and copy from PC to phone by

adb push /somewhere/on/my/PC/nv_data.bin /efs/

use

adb shell

on your pc to get a command promt on the pc that executes commands on the phone. there get root rights if you have a rooted phone:

su

your command promt should now show a '#' instead of a '>'. then you can change the owner of <file> via

chown radio:radio <file>

and change access via

chmod 700 <file>

and maybe check ownership etc by listing the directory:

ls -al /efs

cheerio!

With just a slight adjustment. Instead of "chmod 755 debugfs", I had to use "toolbox chmod 755 debugfs"...

Just in case it can be useful for anyone...

You have no need to do any of that. Simply flash CF-Root and your done.

[Galaxy S II General] sparkym3:
As requested by miloj, I have updated my transformer prime root tool with the changes required to work with the SII. The changes I made were to change mmcblk0p1 to mmcblk0p9 and add added "toolbox" before the chmod call. I have no way of testing this and do not have the drivers for this device so somebody with more knowledge of this device may want to add those pieces if people have questions.

EDIT:A generic version of the tool has been uploaded to this other forum that should work for this device as well as others, but I will leave this version out there as well.

Total Noob

All, I am a total noob to this and could really use the help. Everything seems so convoluted.

I just returned my phone to AT&T because of some issues.I was able to root that one without an issue. However they now provided another phone with ICS on it. I don't want to install a ROM or change the kernel. Just want to use the AT&T software and have it come up the same way just rooted. I saw the GalaxyS2Root.com site but it changes a load up screen picture.

I want to have the ability to load titanium back up and freeze the tethering program so I can tether my tablet.

Once again I just want a simple rooting program with minimal but detailed steps. I appreciate any assistance that you pros can give me.

Forever in your debt!!

Thanks

I formatted my sd card (through cwm) recently to clean out all the old junk. Now my sd transfers are painfully slow. Over an hour to move 2gb. I was on a miui rom before i wiped but then flashed to a cm9kang with a trinity kernel. I assume i had a mod on my sdcard that helped with the transfer speed and i lost it by formatting. Does anyone know what i am missing? Does formatting the sd remove ext4?

Hey guys, ive been tethering for awhile now, and had no problems, just really noticed this after my second month of service.

But, when tethering, HTML web browsing is pretty slow, and my Network Meter widget on my computer says im loading webpages at only 25 -30 KB/s but when i download a torrent/file or anything else (even streaming youtube) my dl speeds go up to 130-208 kB/s. So i thought it was IE9 but then when connected to an actual wifi access point, i experience so issues. Also, i downloaded Google Chrome and the same thing happens. Secondly, when im skyping or oovooing, it will randomly disconnect and hang me up, but yet the icon on my phone says that im still connected to data and everything is fine.

Question is this: Do you think the issue resides in my laptop, phone, WiFi tether app, or T-Mobile network?

I must add both the speedtest app and website (ran from computer) yeild the same speeds. Im completly stumped as to why its like this, im putting my money on the tethering app, but at times when i get kicked off skype and it says i have no internet connection, i try loading a webpage on my phone and it takes a bit longer. (Its really hard to say) but i really need ideas as to where i can start diagnosing and eliminating things.

AS USUAL THANKS GUYS :D

Are you on Magldr? If so, can you test it with cLK? I'm tethering wired and wireless with cLK and it had been pretty fast- the only time I see a lag in losing any page is if the site is a known, slow one (like the Indian Railways reservations site!)...

Im on CLk, i dont like MAGLDR because i have the red key digitizer error. Where the touch screen becomes unresponsive when you use the end key. I might tear it apart and try to fix it someday. But a thought just came across, could T-Mobile somehow know im tethering and throttle me then?

Ah! You didn't mention TMo :) (am on XDA app, can't see it even of you have added it to your profile!)

It's very much a possibility- other TMo users, can you check this one out?

And how do you tether- wifi or wired? Built-in or an app? I use built-in for wireless and the wired tether app. The app shows the speeds in realtime, try it if you already haven't...

Haha sorry man! Wasnt sure if it mattered. But i have a feeling its my phone, as something strange happened just a few minutes ago, i was tethering, and i lost connection, so i enabled Airplane mode, then disabled it, and it said 3 bars of service no matter where i was.. it was like the radio got stuck/froze or something. Im gonna flash another radio just to check it out. Also, i use the WiFi tether for root users app which actualy uses built in wifi tethering. But i cant really see the speeds as my phone only gets 3g on my window sill xD and i use VNC viewer to control my phone from my computer. And the tether app uses the wifi port to monitor speeds, so it goes way high when im controlling my phone with VNC from my computer so its hard to say. Im more convinced its the phone :/ but just dont know what.

I think ive narrowed it down, after changing ROM, RADIO, kernel, location, only one thing made a difference, and that was location.

Are you sure your place has a good signal, and its just the HD2 that is not picking up? Try with another phone. I used to have black-spots in my home a long while back, and used some app for Symbian for my E72 to check the signal strength at various places within the house as well as the cellular towers that is available for me - maybe something like that is available for Android (should be available for sure, is Symbian has it Android will have a million alternative!).
