Fault description:

Nokia 7210 has contact service fault due to bad pm file, in some cases pm file corrupted in mobile so we get this error that when we power on mobile then it just shows contact service message in red letters on screen and then power off after few seconds.  

Fault solution:
1.      First we should flash mobile with latest version. we can flash mobile using any flash tool like mx key or ufs or jaf box or mt box
2. Now check weather problem solve or not if no then apply next step.
3.We have to write full pm file (permanent memory) in mobile. All pm file can be downloaded from support site of our flasher box. For write pm file using mx key we have to follow following steps:-
 A.      First connect mx box to computer


B.      Then select appropriate mobile brand here we should select nokia service tool


C.      Then select appropriate model here we select nokia 7210c rm-436

D.      Then go to service  tab


E.      In service tab open sub tabe PM


F.        Now press load from file here we have to open PM file from our computer location where we had stored it.


G.      Here we select 7210c pm file.


H.      Now write full pm file of all section.



Now contact service problem will solve.
If still we get the error then we have to buy new rpl file from server.
 Conclusion:
PM (permanent memory) file is most risky file in mobile phone because it stores all important data of mobile so during writing pm file we should take care that file should be same as mobile model no. otherwise we will get further many error.
