Nokia N900 dead, flashing cmt-mcusw...sending request 0x50 failed: No error

[Gonercase]

I have got the Nokia N900 phone and I am facing some serious problem on this new phone as it gets rebooted automatically. Actually it boots up to the Nokia Screen and then gets reboot. I have tried to flash this device but it shows me an error as "flashing cmt-mcusw... sending request 0x50 failed: No error".

Possibly your phone needs hard reboot which might solves your problem. Actually you need to pull out the battery out of your phone and then keep your phone off for few minutes and then put the battery at its place and then start your phone. Now check that it moves further then that of Nokia screen or not. If it is not going then I guess you have to reinstall the whole Maemo again on your phone.

As your phone is the latest one then you should not open your phone at any ordinary store as it would be voiding your warranty. I suggest you to give a check to your phone from the Nokia Care as they must be knowing the real issue with your phone. As if there would be any major issue then you should claim for replacement of your mobile phone.

Download the flasher who's file name is maemo_flasher-3.5_2.5.2.2.exe (Version number may of course change to the top). Now install Flash Leads to the downloaded *. exe and installed the tool from anywhere, which I later can easily be reached by console.

1. Turn off Phone
2. Remove battery
3. Nokia N900 connect via USB cable to computer
4. Put back into the battery unit
5. Press the "U" button on the N900
6. Logo appears and stops right above the screen should now see a small USB symbol.
7. "U" key can now be allowed to go
8. Console in admin mode start
Windows button -> search field "CMD" and type in the top right click on cmd.exe -> Run As Administrator
9. have to cd euer_verzeichnis navigate to the directory into which you just installed the Flash software.
10. now it leads the flasher from the command:
flasher-3.5.exe-enable-rd-mode
11. Console command confirms this and a little extra character appears in the display of N900s
12. now remove the USB cable, the phone should now boots up and retrieve the date and time, which must share it.
13th The phone shut down and put the phone back into the USB Service mode. See items 2 to 7!
14. Now you go back into the console and terminated with the RD command mode:
flasher-3.5.exe-enable-rd-mode
15. USB cable from the Nokia N 900 removed. The phone should now reboot normally and the error is fixed!
