A lot of people often hear about "flashing mobile phones" without knowing what it actually means. Flashing a phone means re-installing the phone's firmware files, that is, re-installing the operating system of the phone. When a phone's operating system files are corrupt due to incompatible applications, virus attack and so on, flashing might be the only solution when restoring factory settings doesn't work. Apart from this, flashing a phone too can be used to update the firmware to a newer version, install a cracked firmware, "wake" a dead phone, etc.
You must take in the deep thought that flashing a phone shouldn't be done just for fun as it might be useful and dangerous at the same time. Yes, flashing a phone can wake a dead phone, so also flashing a working phone can kill it!
THE FOLLOWING ARE THE SOFTWARES YOU NEED TO DOWNLOAD TO GET STARTED: you can google them
a. Navifirm - to download the phone's firmware
b. Phoenix Service Suite
c. Nokia PC Suite
d. A good USB cable
1. Install Phoenix. This might take a pretty long time if you're using a slow computer but you've got to be patient
2. Run Navifirm but be sure to have a working internet connection before doing this. It connects to the internet and loads all available Nokia phones firmwares. This too also takes a long time and requires a steady internet connection so you need some patience here too.
3. Be sure your phone's battery is charged to at least 50% though flashing should take less than 10 minutes.
4. Select your phone type under Products. It is located on the phone just beneath the battery. For example, N97's product type is RM-505, RM-133 for N73 and RM-596 for Nokia N8. (You can as well check it by dialling *#0000# in standby.)
5. Wait till it loads Releases. From here, you can see all available firmware versions. Select the latest you find there.
6. It now loads Variants, select your desired product code from the list. You can also check beneath the battery to find the original product code.
7. Now select all the files and download. Select Download with IDMM (Internet Download Manager) if you have it installed it on your PC. If not, select, Download with program and choose the destination folder.
8. Go to C:/Program Files/Nokia/Phoenix/Products
Create a folder with the name as your phone product type.
For example, for Nokia N97, the folder will be named RM-505
The firmware files you downloaded will then be located in C:/Program Files/Nokia/Phoenix/Products/RM-505
9. Now run PHOENIX and connect your mobile phone in PC Suite mode. If phoenix detects your phone automatically, skip steps 110-14.
10. In Phoenix, click File > Manage Connections > New.
11. Now select the type of cable you are using. If you are using DKE-2, CA-53, Micro USB cable, select USB.
12. Click Next. It will find your product and say FOUND. If it doesnâ€™t find any, you can try changing your cable type by clicking Back.
13. Click Next and then Finish.
14. Now your cable type (USB) appears in the connection list. Select it. Click APPLY and then CLOSE.
15. Now select File > Open Product.
16. A list of RM codes will open. Select your phoneâ€™s RM code.
17. Now select File > Scan Product.
18. Your phoneâ€™s firmware info will appear at the extreme bottom of the Phoenix Service Software window.
19. Now select Flashing > Firmware Update. At this point, Phoenix will automatically load the firmware files we talked about in step 8. If it doesn't, make sure you named that directory accordingly and please go over step 8 again.
20. If everything up to step 20 goes well, select â€œRefurbishâ€, wait until the â€œSuccessfulâ€ dialog box appear (DO NOT touch or disconnect the phone or USB cable during the process). Press OK, phone will disconnect and restart.
At the end Phoenix will tell you to disconnect your phone as the flashing has finished butome phones may not boot up automatically after the flashing has finished. In those cases, remove the battery and then insert it and manually start the phone.
