You should open your player up and check the numbers printed on the flash chip to find what actual capacity it is supposed to be. If H2testW is telling you only 197MB is OK and the remainder (755MB?) is bad, and this is littered throughout the drive (as opposed to being concentrated in the front or back area), maybe your player is a genuine 1GB player but they sold you one with defective flash memory instead.

BTW - The MP3 Utilties disk tool encrypted partitioning trick never worked for me - I've alway had to use other disk partitioning tools instead. However, every fake MP4 player and USB player I've seen so far has just been reporting the wrong size so the format utility will allocate available space in the file system beyond the end of the actual device's capacity. This I have remedied by either adding an MBR and using hard disk partitioning techniques (which the MP4 player also understands), or using Linux's mkdosfs command with the drive size override option specified.

PS: I am uploading my 9.5.60 firmware tonight if it hasn't already been posted, but don't consider reflashing your device except as a last resort and when you are already confident of the device's true size.

Hello, I bought two of the 8GB, Gen 5 nano clones on ebay. I ran the H2testw program on both units, one unit appears to be a 2GB, not an 8GB, the other one tests OK at 8GB ( well 7408MB)

I am trying to figure out how to "Un hack" the 2GB unit, but the old process doesn't work, and I have never used linux so the newer guide on here is not very linux-newbie friendly. And I have no clue how to create a new MBR.

So,
first the simple question, is there a relatively easy way to fix these newer 5th gen clones? And if there is, does anyone know where there is a guide that either doesn't use linux, or explains the linux steps in layman terms?

Thanks

Linux has become much easier to use than it was a few years ago. And it has always included the system tools that let you access the disk directly, since drives can be easily mounted and unmounted and accessed directly just like editing a file.

You don't even need to install Linux on your PC anymore in order to use it, as the most popular distributions like Puppy, Knoppix, Ubuntu, Fedora, openSUSE, Mandriva, etc. can boot directly from CD and create a RAM disk for the runtime file system. Mac OS X is pretty much equivilent for this purpose too. Once in Linux, you can unmount the flash drive and then reformat it at a command prompt in the terminal shell window as indicated here...

Can someone help me to remove the hacked memory from this mpx player please? I need it to work, its a fun hardware but its sucks when I don't know the real capacity and overload, also, do you guys know what is the biggest SD card capacity that will work?

anyone can help me. I bought mp4 player from ebay here is link 8GB 2.2" TFT LCD Shakable MP4 MP3 FM 5th Video Player | eBay
and after using 3Gb memory player can not read files after it . how can i solve this problem. Thanks.

I really thank you for this guide. I have just bought a cheap mp4 player, the first one for a little girl. I was too lazy to check the current prices, so I bought from ebay a "16gb" player for 30 euros shipping included from Netherlands. Reading errors soon appeared, files with nonsensical metadata (date, size of several gigabytes) showed up in a new repertory I had just created, directories began to duplicate...
It turns out it is a 4gb player, not so bad after all, but I have written back to the seller (grazy*gadgets)so that others are not ripped off. I see that he has other players in stock :
★ 16GB Mp4 / Mp3 / FM / VIDEO SPELER Zwart + USB Kabel Oortelefoon Handleiding ★ | eBay



As a side note, I followed the old guide (http://mympxplayer.org/image-vp52076.html) and succeeded to format with MP3 Player Disk Tool the player back to its original 4gb NAND size. At the beginning, the memory appeared encrypted and couldn't be formatted on a windows PC.
I have registered here to thank the admin and let the people know that such a 16gb MP4 player is.... dubious.

my player doesnt turn on at all. what do you suggest I do now?

[oliwek]

espowsong, you should be more specific : what model exactly (link to site of purchase?), what did you do to try to turn it on? wer'e you able to turn it on before, or is it a brand new player? explain with as many details as possible, then maybe someone can help.
On the one I have just purchased, you have a slider you have to set on the ON position (not written), then you push on menu (UP) ; keep pressing a few seconds if it is needed.
Of course maybe you have to charge the device a bit if it is brand new (or kept unused for a long time). But the thing is, you have to turn the device ON to be able to charge it up! (that could be a problem with a fully depleted battery)
