After reading several posts, I decided to install the raspbian jessie in a sdcard and insert it in my raspberry pi 1 model B.
This time the raspberry pi managed to boot successfully but the usb ports do not seem to work, the mouse and keyboard do not function at all.
Therefore I thought to connect to the raspberry pi remotely by using putty.
Since the usb ports do not function, I could not use a wifi dongle, so I used an ethernet cable to connect my raspberry pi directly to my router.
Unfortunately it doesn't seem to connect either because I am not able to view the raspberry pi connection on my router control panel.
Please note that:
I have read in https://elinux.org/RPi_Hardware#Power_supply_problems about the polyfuse issue, and measured the voltage between TP1 and TP2 to be 5.51 volts, way above the range between 4.75 and 5.25 volts.
If you think you have a problem with your power supply, it is a good idea to check the actual voltage on the Raspberry Pi circuit board. Two test points labelled TP1 and TP2 are provided on the circuit board to facilitate voltage measurements.
Use a multimeter which is set to the range 20 volts DC (or 20 V =). **You should see a voltage between 4.75 and 5.25 volts**. Anything outside this range indicates that you have a problem with your power supply or your power cable, or the input polyfuse F3. Anything inside, but close to the limits, of this range may indicate a problem.
So there must be an issue with the input polyfuse F3.
Bypassing the polyfuse with a thin wire, will it solve the problem? Or do I need to replace the polyfuse F3?
Please help me and thank you very much for your precious time.
