[ROM] B7610NXXJC3/B7610NXEEJL2/B7610XXJC2

Recommended Posts

There is a B7610NXXJC3/B7610NXEEJL2/B7610XXJC2 - 19.01.2011 ROM on mobile firmware downloader. Does anyone have this ROM and could share it?

PS. Is there any way to upgrade our phones in official way, right now? KIES is not working with my phone and New PC Studio's upgrade function is blocked... :/

JC3??? Really? Coz the latest till now was JC2. Hey guys, can anybody try to verify this? I tried but Samsung Firmware Downloader and Samsung FUS programs are not working now.

@Davka: which mobile downloader are you talking about?

Any update? I tryied to connect to FUS servers, but no response. I am able to download GT-B7610_B7610NXXJC2_B7610NXEEJC2_B7610XXJC1_B7610NXEEJC2_XX_XEE, but if I am looking for B7610NXXJC3/B7610NXEEJL2/B7610XXJC2 there is no response from servers.

I am trying to understand the decryption mechanism by decompiling/reverse engineering the code of Samsun FUS downloader. Its based on public key encryption so we are dependent on Samsung servers for decryption and internet connection is required while decrypting. If successful, i'll make it a standalone application.

I found on XDA http://forum.xda-developers.com/archive/in...p/t-770271.html

info about how to do it. It is for android, but i think it can also work for Win Mobile. We need decrypt key(monitor net trafic to find it) and then we need decodertest application for decoding.

The decrypt key is specific for each model( i hope so), so we need to for b7610.

Info from XDA:

"Now how the F to explain this... its basically using Windows HOSTS file to redirect fus.samsungmobile.com to my own webserver which is hosting MS_TEST/msfus.php which contains the following:

<?php

echo '<?xml version="1.0" encoding="utf-8"?><FUSMsg><FUSHdr><ProtoVer>1.0</ProtoVer><SessionID>560822</SessionID><MsgID>1</MsgID></FUSHdr><FUSBody><Results><CmdRef>2</CmdRef><Status>200</Status><LATEST_FW_VERSION><Data>I9000XXJPD/I9000OXAJPD/I9000XXJPD/I9000XXJPD</Data></LATEST_FW_VERSION></Results><Put><CmdID>1</CmdID><BINARY_CRC><Data>1283028158</Data></BINARY_CRC><BINARY_ENCRYPT_STRING><Data>9780154</Data></BINARY_ENCRYPT_STRING><BINARY_URI><Data>http://fus.samsungmobile.com/Phone_Binary/9/GT-I9000_I9000XXJPD_I9000OXAJPD_I9000XXJPD_I9000XXJPD _XX_XEU.zip.enc</Data></BINARY_URI><DESCRIPTION><Data></Data></DESCRIPTION><GSM_SUPPORT_HIDDEN><Data>0</Data></GSM_SUPPORT_HIDDEN><GSM_NATION_CODE><Data>XX</Data></GSM_NATION_CODE><GSM_SITE_CODE><Data>9</Data></GSM_SITE_CODE><LAST_MODIFIED><Data>10/08/21</Data></LAST_MODIFIED> <LATEST_ANDROIDGSM_PDA_VERSION><Data>I9000XXJPD</Data></LATEST_ANDROIDGSM_PDA_VERSION><LATEST_ANDROIDGSM_CSC_VERSION><Data>I9000OXAJF3</Data></LATEST_ANDROIDGSM_CSC_VERSION><LATEST_ANDROIDGSM_PHONE_VERSION><Data>I9000XXJPD</Data></LATEST_ANDROIDGSM_PHONE_VERSION><LATEST_ANDROIDGSM_CONTENTS_VERSION><Data>I9000XXJPD</Data></LATEST_ANDROIDGSM_CONTENTS_VERSION><DEVICE_ANDROID_PDA_PATH><Data>ADD_Home_cache.tar</Data></DEVICE_ANDROID_PDA_PATH><DEVICE_ANDROID_CSC_PATH><Data></Data></DEVICE_ANDROID_CSC_PATH><DEVICE_ANDROID_PHONE_PATH><Data></Data></DEVICE_ANDROID_PHONE_PATH><DEVICE_ANDROID_CONTENTS_PATH><Data></Data></DEVICE_ANDROID_CONTENTS_PATH><CURRENT_DISPLAYVERSION><Data>I9000XXJF3/I9000OXAJF3/I9000XXJF3/I9000XXJF3</Data></CURRENT_DISPLAYVERSION><LATEST_DISPLAYVERSION><Data>I9000XXJPD/I9000OXAJPD/I9000XXJPD/I9000XXJPD</Data></LATEST_DISPLAYVERSION><ANDROIDGSM_TAR_PATH><Data>ADD_Home_cache.tar</Data></ANDROIDGSM_TAR_PATH><NOTIFY><Data>1</Data></NOTIFY><ANNOUNCE><Data>0</Data></ANNOUNCE><ANNOUNCE_CONTENTS><Data></Data></ANNOUNCE_CONTENTS><REQUIRED_CLIENT_PRODUCT><Data></Data></REQUIRED_CLIENT_PRODUCT><REQUIRED_CLIENT_VERSION><Data></Data></REQUIRED_CLIENT_VERSION></Put></FUSBody></FUSMsg>';

?>

Then i just hosted the JFD firmwares from the real FUS site in my own Phone_Binary/9 directory and KIES will hit my server, get the above info, and hit my server for the .enc file.

Easy as hell.. works a treat... you could setup a localhost Apache/whatever server and alias fus.samsungmobile.com -> 127.0.0.1 and achieve the same thing with a few simple downloads..."

@Dasklos: What decoder are u talking about? Can you please explain in a bit more detail?

info from XDA:

get both files, the fw and the decoder

2. put the fw and the extracted decoder in the same folder e.g. on desktop the folder JPH

3. open your dos command box (start -> run --> cmd)

4. go to the correct path in my example it would be

C:\Dokumente und Einstellungen\Admin\Desktop\JPH>

of course you have to adjust this one to your language and username

5. type in "decodertest.exe filename pwd"

filename=GT-I9000_I9000XXJPH_I9000OXAJPH_I9000XXJPH_I9000XXJPH _XX_XEU.enc.zip.enc

pwd=87253

6. wait a lil bit, done

Somebody created decodertest.exe application., but we will need decryption key. Link for decoder:

oh and how will one get this password thing? Is it available on the Samsung server somehow, in some form? Anybody has any idea? I am asking this because as per my analysis of the FUS downloaded its based on public key encryption technology which does not involve passwords like this. Its more like a long string in the case of these kind of encryption techniques.

"Under this topic you can make firmware query and download requests for your Samsung Mobile device. I will ask you for a donation of 1 € for each firmware query request and 5 € for each firmware download request. "

the fastest way to get it :D
