Default NWZ-E436F Firmware Won't Update

Hi - After searching here and elsewhere for a couple of days, and contacting Sony, I can't find a solution. Trying to update v 1.00 to 1.02 on my wife's E436F (she loves it - 1st MP3 player, although taking that into consideration, she likes the quality sound, ease of navigating, storing songs, size of display) -- Vista home premium. Walkman shows as an MTP item.

The updater window appears with the "Current Firmware Version" and "Upgrade Firmware Version" fields blank. As it progresses, another window appears: "Unable to write to device. Device timeout." I remove that window. The updater window now shows "Current" ver as 0.00, and "Upgrade" as "1.02". I'm now given "Start" as an option, so I did that. End result, no change.

The Sony instructions say if 0.00 appears, unplug the unit, close all programs, start over. Tried that several times, plus rebooting. No change.

I first tried this in Jan 2009 (bought in Dec 2008), w/same result. Sony (on phone) said (in Jan, and now in Apr) to save all songs/pictures, etc., and Format. I tried that in Jan, but no change. Tried the reset button -- no change. I've not tried the Format nor reset again in Apr.

Tried updating as a USB item instead of an MTP - definitely doesn't work - keeps telling me to connect device.

Any clues to this obstacle ?

The unit works just fine (yes, it does have the little pre-programmed quirks mentioned in these forums for the E-Series units).

BTW, I did notice, when new, and now, that when volume level is halfway, it wasn't as loud as I expected. However, 20-25 (max) is more than sufficient. I'm 55 with some high-end hearing loss, and when younger I used to really want to "feel" the music. Well, I can "feel" it just fine at level 20-25 - I don't need it any louder. I "want" it louder, but that's different than "need." For those that say the E-series units aren't loud enough, either you're already partially deaf, or "simply loud" isn't good enough for you -- you want to "feel" it !!! Well, you may be (will be) sorry later. That said, I sure enjoyed it at "blast" level when younger. There's always a price to be paid, isn't there ?

Hi LsWalk,
Mine came with 1.02 already loaded so I can't be of much help with this one. Have you installed the Sony software that came with the player, I know the Creative Software I got with an old player would automatically update the firmware. Maybe the Sony one has a similar function. If you're still stuck after trying that I personally would exchange the player under guarantee just in case later firmware adds useful functions.
With regard to the volume, you are right that it is adequate for headphone use and I certainly don't want to risk damaging my hearing. The problem for me is that I listen to the player a lot in the car through an FM transmitter but because of the low output of this player I have to turn up the car stereo much more than with other players that I own and radio interferance becomes a real pain.

Default NWZ-E436F Firmware Update Successful

Well, I finally got the E436F to update. I tried it on my work's laptop, which has WinXP Pro, and it worked first time. I've also recently bought, from Sony (couldn't find it anywhere else around the Atlanta, GA area), an NWZ-S638F, and it updated from 1.10 to 1.11 just fine. It did it differently - not the same kind of update windows. A nice touch was the option to engrave up to two lines on the back, for FREE, which I took advantage of.

The sound has many more settings, and is definitely louder at the same volume numbers than the E436F (which is my wife's, and is plenty loud for her). The headphones, whose ends look like they're broken, 'cause they're canted to one side, are really good. I don't know if it's the unit (I think they both go to 20K), or the headphones, but I could hear many more little high-end sounds. I'll try it on her Walkman, and on my CD player.

The "creating library" process is a LOT quicker (about the same number of songs, videos).

One thing that I thought was a MAJOR display problem, but turned out it wasn't (thought I'd have to send it back right out of the box) -- there were several barely-lit vertical lines of slightly different lengths stretching from top to about 3/4's the way down the display.

It looked like a major pixel problem, but was just the idiotic Wallpaper 2 ! I thought maybe the engraving messed up the pixels, but thankfully it was only someone's bad idea for a wallpaper.

Thanks for the suggestions!
