If the Flash IC/Memory IC damaged for any reasons or Its program/firmware corrupt due to any reason then the Main controller does not get any boot/basic information and the device does not turn on. In this situation, we need to reprogram the flash ic with the matched hardware dump/flash file to get the device in normal condition.
Here are some china satellite receiver’s Dump/Flash files for free download: S.No.

For Knowledge Purpose i will be explaining briefly the sizes of satellite dish and there conversion to different unit. We have a very common sizes been used frequently which is meter for example we hear of 1m. 1.5m, 1.8, 2.4m, etc. Also we hear of 60cm, 90cm, 8feet, 24feet, etc. 
Yea if you have ever wondered just like i did sometime ago about feet. Because i was a little confused until i understood the simple arithmetic that is been involved. Its a common mathematics that me and you know of in our early school days. Now lets go there.
Get you pen and paper we are going to solve some mathematics today: 100 centimeters ==> 1 m 3.28 feets ==> 1 m from the above we should now know that it takes 100cm for us to get 1m and likewise it will take 3.28feet before a meter can be obtained. Example1: Convert (1.) 60cm (2.) 90cm to meter Solution: 1. Recall: 100cm ==> 1m therefore; 60cm ==> Xm Cross multiply 100 multiply by Xm == 100Xm 60 multiply by 1 == 60 now we divide 100Xm by 60 100/60 = 0.60m therefore 60cm = 0.60m to convert to feet. Recall 3.28 feet ==> 1m therefore; X feet ==> 0.60m cross multiply 3.28 multiply by 0.60 ==> 1.97X multiply by 1 ==> X therefore 60cm = 0.60m = 1.97feet. Do that of 90cm on your own.
From the above just use the procedure to solve and calculate your feet Further Examples: how many meters is in 8 feet. Now we know that; 3.28feets ==> 1m therefore; 8feets ==> Xm cross multiply 3.28 multiply by x = 3.28X 8 multiply by 1 = 8 now divide through by 3.28 we have 8/3.28 = 2.4m therefore: 8feet is = 2.4m. Concluding simple easy calculation. HOW TO REVIVE DEAD SRT 4950M/4950H ONLY Despite the fact that the warning I gave you before upgrading I will still find many that will brick their decoder coincidencely and carelessly that’s why I will give you the software to revive the decoder after it get brick. ===>Download Revive file for SRT 4950H and SRT 4950M or rename any of the above software to ROM.bin STEPS TO REVIVE DEAD SRT 4950 1.
Rename and copy the file into memory card or pendrive and make sure the file is the only one inside the memory card or pendrive and make sure it is virus free 2. Insert the memory card/pendrive into your decoder through USB port. Power on your decoder and wait for 5seconds, check if the front panel shows upgrade process but if it fail that’s means you needs to change the memory card or pendrive and you are done if it works and reboot successfully after the upgrading.
