Sadikk posted a topic in Tutorial and GuidesYou reading this post because you have an imported/foreign CDMA handset with you and its ESN/MEID is registered in Reliance database. If ESN/MEID is not registered then you can check this topic. Now you want this handset to be working on India's Largest and RIMweb's beloved CDMA network! Though this area is little tricky for n00b's, past knowledge of CDMA development plays a key role. But if you don't have anyone this post will help you (hopefully); fingers crossed! PLEASE NOTE THIS PROCESS CAN GET YOU VERY EXPENSIVE AND ULTRA MODERN PAPERWEIGHT. SO YOU SHOULD KNOW WHAT YOU DOING. IF YOU DON'T WANT THAT TO HAPPEN THEN GET IT DONE WITH THE HELP SOMEONE AS MENTIONED IN THE FAQ TOPIC. Prerequisites 1) CDMA 800 Mhz handset (Which ofcourse you have) with its data cable. 2) CDMA workshop v 2.7 (though there are more softwares to do it, this is used commonly) - Use Google to find 2a) There is a possibility that your handset isn't supported by CDMA Workshop v 2.7. In that case you need QPST - Use Google to find 3) Knowledge of how to put your particular handset in DIAGNOSTIC mode along with its driver. You can Google that out. 3a) Though I have personally done 100's of different handset models, keeping track of each handset model is difficult. So I am mentioning the most common DIAG mode enabler below: HTC Handsets: ##3424# or ##3424+Call button. Palm/HP: ##8727277# Samsung: ##8778# and select modem. BlackBerry DIAG behaves on virtual port created by installing BlackBerry DM. This list will be huge if i keep writing. So I'll suggest if your handset isn't mentioned in this list then please ask on this topic and I will try to reply with your enabling DIAG solution. 4) Diagnostic Driver for your device. (There are so many handsets and usually there are different drivers for each devices, so this is something you have to request here, commonly used DIAG Drivers - Google for it) 5) Windows PC with XP or Win 7 32 bit. (Its very difficult to find 64 bit drivers so I'll keep and support this tutorial for 32 bit only) 6) Carrier specific NAM PRL or Preferred Roaming list file. (Check the pinned topics in Technical forum) 7) A-key or Authorization key. (will be provided by ESN/MEID Registrar or handset seller) 8) Your handset's SPC (check your handset cover box or ask your handset seller). How to / Step by Step: Note - There are many handsets/models and each time process is little different. But basic changes to latch your phone to Reliance network is mentioned here. I am using HTC DEVICE to do it for Tutorial. 1) Pick your phone and enable Diagnostic mode in it. ( I am using HTC HERO and so i punch: ##3424#). Please find your phone DIAG enabler in prerequisites above. 2) Connect your Phone to PC using Data cable and let the Driver search process begin. (mostly Driver installation failed and you have to do it manually) See pic or video. 3) Now open CDMA workshop (You might have to disable your antivirus, as the crack for CDMA workshop uses Trojan pattern) 4) Open Device manager and expand Ports (COM & LPT) there u see which COM PORT assigned for your device. In my case its Com PORT 7 5) Select that comport on CDMA workshop and press connect. and press read. 6) Go to security Tab and enter SPC and press SEND button. return message should be SPC COrrect Phone unlocked See pic. 7) Now go to Nam Tab and press load and select Reliance.nam and press write. 8) Go to CAVE and enter your akey and press write. (You might have to calculate akey, see pic for details on calculation) 9) Go to Other tab and press write under PRL select Reliance.PRL file return message should be success. 10) Now your phone is flashed on Reliance CDMA network. :thumbup: :thumbup: Note - Now after this process you need to visit Reliance webworld to transfer ur number from existing handset/RUIM to this phone. U can also use HCC (Handset Change Card) if its available and work in ur city/state. Hope you enjoy flashing your phone. Thanks. EVDO Activation & Configuration For questions related to generating the NV dump file with EVDO parameters and submitting EVDO activation request, please check the FAQ topic. If you have the NV dump file from your handset seller or MEID/ESN registrar, you can follow these steps to upload the NV dump file to start using EVDO: 1) Go to "Security" tab in CDMA Workshop and Send the SPC as explained earlier in this topic. 2) Once it showed that the phone has been unlocked, go to the "Memory" tab and click "Write" under "NV Items" 3) Clik OK when it shows that you have to send the SPC and then you will be able to select the NV dump file. Browse and select the file. Sample file name is like "MEIDnumber@hrpd.rcom.co.in-net-NVItem-Script-PPP-HDR-27.txt" 4) Submit the file and it will show that the NV items have been written successfully. Now restart the handset and EVDO should work fine if the EVDO activation has been done already at Reliance.
