I am starting this topic for understanding the NV item and generating new dump file when we change or sell our Phones. If you see the NV items received from your seller you can understand that basically we have to change 37 items in Phone’s actual NV adresses in order to use it on Reliance CDMA… These are
0714 (0x02CA) 0460 (0x01CC) 0461 (0x01CD) 4396 (0x112C)
0463 (0x01CF) 0464 (0x01D0) 0462 (0x01CE) 0495 (0x01EF)
0546 (0x0222) 1907 (0x0773) 0465 (0x01D1) 2825 (0x0B09)
0466 (0x01D2) 0465 (0x01D1) 2825 (0x0B09) 0466 (0x01D2)
0465 (0x01D1) 2825 (0x0B09) 0466 (0x01D2) 0465 (0x01D1)
2825 (0x0B09) 0466 (0x01D2) 0465 (0x01D1) 2825 (0x0B09)
0466 (0x01D2) 0465 (0x01D1) 2825 (0x0B09) 0466 (0x01D2)
0459 (0x01CB) 1194 (0x04AA) 0579 (0x0243) 1192 (0x04A8)
0580 (0x0244) 2953 (0x0B89) 0910 (0x038E) 0906 (0x038A)
8035 (0x1F63)
You can see that many addresses are repeated in dump file. Please note that its just the location of addresses where we have to input the value. Input value will be same for all similar address. For example 0465 is repeated 6 times but value for all 0465 address will be same.
Now for understading what these address refers to you can go through the following topic of XDA :
http://forum.xda-developers.com/showthread.php?p=33230579
Don’t worry about the long list in above tutorial; what we need to understand is basically 4-5 items only. Most of the addresses in above 37 items have same value. I will group the address together which are having same value :
ADDRESS VALUE
0465, 2825, 2953, 910, 906 net
579,1194 meid@hrpd.rcom.co.in (Replace meid with your Phones MEID)
466 HIGHLYSECRETWORDnet
580,1192 MIN
REST ALL Leave it as it was in old dump file
Now if you have any latest NV dump file then basically you have to edit only 579,1194,580 & 1192 as value of all other addresses will remain same in new dump file also. Please care that older NV dump file may have different values because previously we were using our MDN as Username and Password i.e. 0465, 2825, 2953, 910, 906 has to be changed to “net” in older Dump file. Similarly you will find HIGHLYSECRETWORD(your MDN) in address 0466.
All these addresses are entered in HEX Format in Dump so to understand dump file and to edit it you need a ASCii to HEX Calculator. I used following online tool for this :
http://www.asciitohex.com/
Just copy the ASCii value in text box of above calculator and click Convert. Then check the Hexadecimal Box for corresponding Hex Value. Now enter this value in dump file one by one.
Replace the small alphabet to Capital while entering in Dump file. Also dont edit the first Hex value in address as it defines the location. e.g:
After editing the Dump file you can upload it to your phone using following topic:

Please note that above editing is for 1x only as I am not able to understand address 580 & 1192. If you put your MIN in these address you will get 1x but for EVDO I believe something else has to be entered. I have tried this method on 3-4 phones and was able to get 1x. (Tried on HTC EVO3D & Samsung Fascinate.)
My purpose for writing this tutorial is purely to avoid bothering our gurus/sellers again and again for NV dump. I may not be correct in my understanding and request all Gurus to correct and shade some more light on it. I thanks Hetal & Dr. Muffaddal for their help and many tutorials and offcourse Parin who send me every now and then NV dump for various phones.
