Samsung Galaxy S4 MT6572 GT-I9500 no service solution !!! topic

hello ! after a week of testing ive finally found a solution for samsung galaxy s4 clone ( mt6572 gt-i9500 ). with no service !

Soo , you have no service and can't make calls ! follow this instructions and you will be talking on your phone in no time ;)

Its very simple : ( i'll add the necessary links / software for this job )

1. you need SP_Flash_Tool_exe_v3.1316.0.150 ( you can easy google this one )

2. you need the WORKING ROM ! http://www.4shared.com/rar/9ClKLRR2c...8012a_fwv.html

3. you need MtkDroidTools http://www.4shared.com/rar/KcOfy4tdb...roidTools.html
( this version is allready modified to work with mt6572 )



The procedure :

we must first format the phone using SP_Flash_Tool_exe_v3.1316.0.150 . soo we open the program and select the scatter file.txt atached in the rom . hit format and then hit OK.
Now remove the battery and connect the usb cable to the phone. it will start formatting the phone. wait till is ready ( you will see a green circle )

At this point , the phone is ready to receive the new ROM

you have allready selected the scatter file early'r .

THIS STEP IS VERY IMPORTANT !!! uncheck the CACHE and USRDATA at the bottom.

Now hit Download button , you will get a warning message, just press YES
Now put the baterry back into the phone, and connect the usb cable. wait till the process end's and when you see the green circle you can disconect the phone, remove the battery, insert back the battery and power on the phone , and voila !! your phone have working network !!

Next step is to write the IMEI...

Use MtkDroidTools ( you must have debugging mode on in the phone ) connect the phone to the usb cable, wait till MtkDroidTools see your phone , and then hit the big imei button. There you must provide the imei number ( you can find it under the battery ) after that you hit write imei and then reset your phone and you are good to go ;)


I presume that you allready have the usb drivers ( if not, i can also provide them )

For other questions use the forum below ;)

[MT6572 Primo F2] SIM not detected, pttycmd1 not found, NVRAM empty topic

I 'whole formatted' my MT6572 based Walton Primo F2 phone with SP Flash Tool.
Then I flashed the official firmware of this phone with SP Flash Tool.
Now the phone works fine but it does not detect SIM.
Also, the IMEI is shown as 'Invalid' for both SIM slots when I input *#06#.
When I try to fix IMEI from MTK Droid Tools it shows 'ERROR : pttycmd1 device NOT found!'.
Also, MTK Droid Tools shows 'Baseband v: -----'.
I am sure the problem is that when I formatted the phone it wiped the NVRAM region too.
So the phone has no baseband or radio files right now.
Although, WiFi still works perfectly.
Now the official firmware of Primo F2 does not contain any nvram.bin file.
It does contain a BPLGU file but I can't seem to modify IMEI with SN Write Station or Maui META etc.
Probably SN Write Station and Maui META etc. only modify IMEI when baseband or radio files are already present on the phone.
So I think the only way out for me is to flash a nvram.bin with SP Flash Tool.
Any ideas whether I am on the right track or not?
If I am, then how can I get nvram.bin file for my phone?
Can it be generated from BPLGU file somehow?
As you people can see that I have tried a lot of things, so please suggest/advise accordingly.
Any help would be appreciated :)
