amit.shippie 135 Report post Posted March 6, 2013 (edited) 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: http://www.rimweb.in/forums/topic/33225-tutorial-flashing-your-cdma-handset-after-meidesn-registration/?p=255120 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.

nikme 177 Report post Posted March 7, 2013 (edited) the main reason we need nv dump is for hdr password which is different for different phones so even after decoding nv you will need hdr password which means contact your seller for that or the person who registers the meid.again for 1x this will work on htc and samsung phones but motorola and lg phones need mobile + simple ip so there nv has to be little different.<br /> Edited March 7, 2013 by nikme 1 Share this post Link to post Share on other sites
amit.shippie 135 Report post Posted March 7, 2013 (edited) ^^^you are correct nik but if seller gives the HDR password once it will be same always... right??...so there wont be trouble for them again and again... For Motorola Its really difficult I have gone through the post on mobile5.in... Edited March 7, 2013 by amit.shippie Share this post Link to post Share on other sites

st_7 138 Report post Posted March 7, 2013 Hi amit great post, this is the first post I've liked in Rimweb.in, always wanted someone to post this info for the same reason you posted here, that is to get rid off the hassle for both buyers & seller everytime the buyer changes his/her number. There used to be a simple nv item file generator @ mobile5, but it was taken out. Glad that atlast someone sensed the necessity to have post like this. A win-win situation for both sellers & buyers. Once again thanks for the detailed information 1 Share this post Link to post Share on other sites

neerajayshree 36 Report post Posted March 8, 2013 First Place Amit nice iniatieve i dont have Data Working on my LG Spectrum How do I go about creating this NV FILE for the same. I cant be dependent on my seller (Abhishek Pujara) I had CW and read the NV file and saved it. It had some bad-patches reported ( what was the significance of it I don't know) Can i make changes to the NV file saved and upload it. the main reason we need nv dump is for hdr password which is different for different phones so even after decoding nv you will need hdr password which means contact your seller for that or the person who registers the meid.again for 1x this will work on htc and samsung phones but motorola and lg phones need mobile + simple ip so there nv has to be little different. nick you said it is different in what way would it be different for LG and MOTO ? can you eloborate Regards Niraj Share this post Link to post Share on other sites
nikme 177 Report post Posted March 8, 2013 (edited) simply writing the nv won't activate data on lg spectrum you can try the nv from lg marquee post which zeroes out some nvs which is required for data.Sent from my SPH-L710 using Tapatalk 2 Edited March 8, 2013 by nikme Share this post Link to post Share on other sites

dr.faramroze 703 Report post Posted October 8, 2014 Yes you can surely take NV backup. It is always a good practice. Experienced guys should take EFS backups also as each android build of each device has different EFS partition size and useful during "baseband unknown" issues.
