hi guys im in a big problem
im new to root i open QPST i was trying to do stuff and i changed my phone # by accredited and now i cant call anyone and when someone calls me no one answers i tried to change it to my number but it didnt workk plzzzz helppp

also my 3g is still working
hmm well the problem obviously came from making those changes and you say you changed them back but did make sure to change EVERYTHING back? i would probably suggest to do a factory reset and see if that works. also in the future dont try to use QPST unless you know what you are actually doing. if worst comes onto the table, you should unroot and then go to your local MetroPCS store and see if the ycan fix it or get it replaced
you could also try this but i doubt that this would even work but its worth a shot:
1- Download QPST (Free Software,
Click Here)
2- Get your own SPC Number
Click Here & Enter Your MEID. That will be your key to unlock the phone and your password. Your MEID could be found at Settings->About Phone->Status ... it's all numbers
3- Got to Start-->All Programs-->QPST-->QPST Configuration.
4- Select your phone from the list (the phone should be in Debug Mode).
5- If you don't see your phone Click on "Add New Port" uncheck "Show Serial ....blablabla" and select the port and add it.
6- With your phone selected go to Start Clients-->Service Programing. Select the phone and click OK.
7- If a dialog came up telling you to retry click on retry.
8- Click on "Read from Phone" you will be asked for your SPC number to unlock the phone and get its information.
**** BE REALLY CAREFUL AFTER THIS POINT YOU COULD MISS-UP YOUR SERVICE AND FLASHING YOUR PHONE WILL NOT RESTORE THESE SETTING... SO TAKE EXTRA CARE FROM THIS POINT ON***
9- Go to M.IP tab and select profile 0 and edit your user name remove the "aaak." just for the first row.
10- Go to PPP Config-->Um change the user name (
Your Phone#@mymetropcs.com) and insert your SPC as the password
11- Go to PPP Config-->An change the user name (
Your Phone#@mymetropcs.com) and insert your SPC as the password
12- M.IP tab change the mobile ip behavior to: simple IP only (thanks to oscarher4)
Write to Phone (the phone should restart by itself)
EDIT: wait when you tried to change it back did you make sure to click read from phone to get the new information and then changed it to the original and then write to phone?
