M6 SL trouble

Hi, i posted this problem on meizu.com with little help so far b4 i remembered this site. This is mostly copy/paste from a couple of my posts there.

Issue:
When playing some of my own converted videos the player simply get stuck sometimes. It goes black just after trying to start a video and i'm unable to reset it in any way. It's not turned off since i can still see the background light in the edges. The only solution so far has been to wait for the player to run out of power and charge it back up. After that it's back to normal....till i try play another video =/ Some videos work and some don't. It's not the files that is damaged, that i've tested. It seems that it might depend on position on the disc..

I have a small theory that it might be a damaged "sector" on the storage unit. As far as that's possible on a flash-disk.
In that case could reformatting the disc and installing new firmware help?

Any tip on what this can be and any solutions would be appreciated.

Reinstalled the firmware (2004.7 version). This didn't change my problem though and my files wasn't deleted in the process as i expected. I wanted a full reformatting of the disc.
Atm the player is stuck and i have to wait till the battery is flat to try something else =/

What i wanted to do is to hook up the player to my PC and wipe the disc clean by formatting it and build the disc back up (does it support NTFS or FAT32?). Then reinstall the firmware. My question is then: Will i be able to install the firmware if the disc is wiped clean like this?

patching together these posts made quite a few questions =/ replies to any of them is appreciated.

tnx in advance, warjar

edit:
Just found out it's currently on FAT32 and seems to be able to be formatted as NTFS. still if changing to NTFS is a bad call.. let me know =)

If the player refuses to play a video it's most likely the video itself that is converted outside the requirements (wrong codec, bitrate too high etc.) or if there is no space left on the device (needed for buffering).

Maybe you should try to convert it with a different program (e.g. Batman).

There are "damaged sectors" on flash drives, but they are not used since the controller locks them.
Formatting as NTFS is not recommended because the features of this format also produce much more wear and tear on the flash drive which will cause it to wear out much faster (don't know if the player can handle it anyway).

If the player freezes you should be able to force it to shut down by pressing the Play/On/Off button for 10-20 seconds (reset), this has always worked for me.

Tnx for your repply

The video files them selves shouldn't be the problem. I spend a lot of time with different converter programs and different settings, bitrates to try find the optimal format. The files that is "failing" is among a long string of files i converted the exact same way. 160 files at least, and used Batman for all of them with the 90 degree flip (which was my biggest prob with other converters).

Damaged sectors: This is why i want to do a full formatting of the drive. I have a small theory from personal experience that these damaged areas might not be excluded yet. I believe this happens in the process of rebuilding the discs structure. Such as after an full formatting. Haven't read up on these things so its just a gut feeling.

I have tried pressing the Play-button for a long while, but perhaps not long enough =/ Will try that again next time.

I will stick to FAT32 as u recommended, don't really need the 2GB+ filesize-support on the 4GB drive anyway =)

the restart-function worked =) can't understand how i've missed out on that function =/ (got Chinese manual tho) tnx ALOT for that, now my problems are manageable.

Been messing around with formatting the disc and such. A few failed attempts when formatting was unable to complete and not allowing me to access the disc again =/ Even tho, the reset-functions on the player seems to make this all pretty fool-proof no matter how bad it might seem =)

my problems showed up again after a little while, but the restart-function now allows me to investigate the reason. It seems now that it might be the files them selves after all. Perhaps a small glitch in the conversion that MEIZU can't handle.

Thanks again for confirming that there was a restart-function after all. That changed everything for me.

Problem "solved". Thanks!

It would still surprise me if it is really a "bad sector" that is making your M6 crash when you play videos. To proof this, you could copy the same movie 3 times with different names and see if they all make your player crash at the same time code. That would be a hint that it can't be a bad sector.

Yes, my first thought when this happened was that it was due to a damaged file when i first encountered this problem about 3 months ago (I was at a vacation when it happened and had limited limited options for fail-testing). And i did try to place the same problem-file on different areas of the disc like u said, but since i didn't get the restart-function to work it took me 8-10+ hours between ever time i was able to test it. The few times i tried it seemed to apply that the files was working, but just as well might have mixed the damaged ones and the working ones up over this timespan. In addition the problem-files worked perfectly in windows and showed now different in spec (resolution etc.)...hence my hasty conclusion.

Now that i can reset and test again almost instantly i'm pretty sure its just individual files that are damaged. Still it's a bit weird after having played perhaps 30-40 working files suddenly every other file is now damaged. All is converted the same way and at approximately the same time (same codecs and all).

Sorry for "spamming" all this after i've got my prob solved. Just in case there would be others with a similar "problem" out there =)

the M6 is a bit picky with video files, and since Meizu has never made the exact specs public, we just don't know what makes it crash exactly. I have tested a lot with BatMan and several input and output methods, so I got finally a way that would work 99%. Your video seems to be one of the 1% that don't work. Try to preconvert it with virtualdub and a very high bitrate first, then throw it at BatMan.
