Sansa e250 v2 -- no radio, no time, no voice

(1/3) > >>

rekkataichou:
Hello all,

I just came from un-bricking my Sansa e250 v2 over at AbiP and I thought I had my music/gaming/radio back now with the latest Rockbox & Bootloader -- and I almost did.

I have three two three major stumbling blocks:

[*]I can't use the voice-recorder -- somehow that fixed itself screwed up again. I can record in the OF (I've tested for files up to a minute long), but if I try to delete a recording, it freezes up. If I go back, I can see the recording has been deleted, but the Voice playlist says its still there. (The OF freezes up when trying to delete files in general.) In RB, a few seconds after entering Recorder, the screen freezes. (But the screen-saver still responds to key-presses.)
.
[*]As said in the title, the radio also doesn't work. Under RB, clicking FM Radio does nothing or it causes a lock-up. (If I press power, the screen fades in and the wheel lights up, but everything is still locked.) In the OF, the radio commands are full functional, but it doesn't get any signal.
.
[*]The time is not kept at all. RB has the clock stuck on 6:28:15 AM Feb 7 2006 all the time. Even the App "Clock" has the hand stuck. The OF is slight better about this; it starts with 2007/9/24 12:00 and will gradually change if left on. If you change any setting and hit apply, when you return to Time/Date you get 1970/1/1 12:00. When I just unbricked my Sansa, the clock was fine and --amazing-- current. Despite my repeated battery drains and removals, it still had something close to the current date and time. When I tried correcting things is when it just said NO.[/list]
.
Looked through the posts this forum dating back to 2009, but haven't found anything like this. (There was a complaint somewhere else on the website, but not under "Repairing and Upgrading Rockbox Capable Players" -- and it went unanswered.)

I'm hoping someone knows what might be going on. And if you have time, here's the TL;DR version of how this happened in the first place:


--- Quote ---I believe I bricked it in the first place trying to hot-swap the microSD card while it was charging in a mobile USB docking device. The microSD cards had no issue, but the Sansa (in Original Firmware) would no longer have the correct font to display "now connected" -- it would just be a series of blocks. When I tried connecting it to my PC, Windows and PuppyLinux could not discover the device.

RockBox would load just fine however, but a few of the files saved to the Sansa (and not the FAT32 microSD) had their names completely mangled and I couldn't delete them off the device without freezing up RB (ver 2.x, bootloader 1.0). So, on one of the lone instances Windows recognized the device, I formatted the entire thing... big mistake as that meant I couldn't have access to Rockbox at all and the OF wouldn't get past the "Sansa" opening movie.

Opening up my Sansa v2 (it was a v2; the Flash chip was on the board, the board said 1.5+ -- and there was something fuzzy on the pen-battery inside), I did the "short these two points while mounting the drive" to unbrick it. It did work. The Sansa was recognized as a USB device. I was able to flash it with the latest SanDisk firmware (v03.01.16A) and install RockBox 3.6 (Bootloader 1.27) on it.

And I thought that was it.

Except the fade-out on the wheel didn't work so well; the blue light would dim and flicker, but not turn off. The OF was randomly activating the Hold button. I decided to format the machine using the OF format option, re-install the Sansa firmware, OF format again, and then install RockBox.

And here I am. I'll admit that my Sansa can still play music and games, and I'm satisfied with that. But I'd like to have all the features available if possible -- the mic on this baby is amazing!

Are you using 3.6 ? This is fixed in current builds

rekkataichou:
Thanks for the reply.
I should be. (Yup, boot-screen says 3.6.) I installed this over the weekend using the 1.2.7 installer. I was a bit worried about manually installing on an unbricked system.

If I can immediately start recording, the system won't lock up. But if I leave the recorder on for a few seconds (3~9) with the recording bars in flux, it is very likely to lock up.

I say lock up because I am just testing it now and, while the screen is stuck, the recorder is still "active." As the RB screen is stuck on the Recording bars, I can hear the amplified sound coming from my headphones.

I saw from FlySpray someone was having this issue with their Fuze this week.

If you want recording just use a current build, they work fine and USB works with rockbox, no need to reboot.

Thanks, but I am already using the current build. And unfortunately recording does not work fine with my recently un-bricked Sansa e250 v2.

If I do not immediately scroll to the "record" button and start recording when I enter the recorder menu, the system will lock up and I will need to reboot.

When I connect Rockbox to a Windows PC with the select button held down, my Sansa gets recharged. Is it normal that Windows does not recognize it as a USB device? (If I don't hold the select button, the OF starts up -- and once the database updates itself -- is recognized by Windows XP.)

My theory as to how I bricked my Sansa in the first place was that I was using a USB wall-charger to charge it instead of  the proprietary cable and a computer.
