My iRiver T-10 has worked fine from last year Dec until now. when i lock in securely the earphone pin into the earphone jack i only hear one channel. if i put it in half way i hear both channels but then the pin will at tiimes fall out when i am walking. how do i fix it?
Try another headset to be sure its a problem of the player and not broken headphones.
if its the player i hope its still under warranty, else you need to open it whats wrong.
hot air soldering machine is an advantage..

You will need professional help on this, the laptop must be dismantled down to the motherboard level to access the problem. The earphone jack may have to be replaced and requires a high degree of solder skills to remedy the situation.
Most earphone jacks have two functions. One, to provide signal to a set of earphones or headphones. Two, to DISCONNECT the path that would be amplified and sent to loudspeakers. If that particular contact on the jack is bent or broken, when you UNPLUG the male jack, the connection is NOT re-established!
there is a broken solder joint where it is on the pc board.it is not the earbud itself,because when you pull it out,both sides work.the jack has 3 sections,the tip which is one side,the next piece,which is the other side,and the shank piece which is the ground.the ground connects to the outside ring of the headphone jack.there are 2 contact points inside for the two channels.what happens is the copper foil of the pc board fractures where the pins are soldered.scrape away some of the foil so that copper is exposed for the pins,and resolder it and it will work if you wiggle the jack,you will see the whole piece of circuit board move where it is cracked.after fixing it,put epoxy over the area to make it stronger.
Interesting problem but I have repaired this problem before. This is not going to be something you can fix yourself.....believe me... I have 30 years of experience in Electronics.
The headphone jack either has to be resoldered or replaced. When its loose, in most cases the pins of the jack are broken and/or the printed circuit board tracks have been torn off the board. The jack is a surface mount part.
A new jack must be installed but there is no way to solder in a new jack because the printed circuit board tracks are gone. The new jack must be installed with epoxy to the board and new wires have to be soldered from the printed circuit board to the jack.
There's around 2 hrs worth of work involved in this repair.
have you tried playing it in ole iriver style (not rockbox). to see if you really did delete something. and if so go to www.iriver.com and download the the last firmware you had to rebuild. and hopefully you can come back to rockbox latest version also. its just a very late suggestion. oh yeah one more do you know of any one who has a 120 as yours (you can copy theirs software, but you will have to format yours in order for it to work correctly)
Call Sandisk and tell them about your problem. I had the same exact problem. The headphone jack inside is loose. Talk to Sandisk and don't worry about the box, the customer is always right. But after they send you a new sansa e250, sell it on ebay and buy a durable mp3 player like the iriver t10 series. My old iriver dropped on the floor plenty of times and it's still working after 3 years.
