Re: Wanted : Hacked chip recovery testers
 

i think im almost there the only problem left is i dont have a backup.log in testdisk could you post it and the location it needs to be stored or should i create it using another device ????

dailyroach, Just create a text file, paste the info into it save and name it backup.log, place it in testdisk-6.4\win where the testdisk_win.exe resides.

Re: Wanted : Hacked chip recovery testers
 

sorry to post twice

testdisk encounters read errors after cylinder 60 is this normal or is the chip screwed now

dailyroach, If that is the case then the chip is not really 2GB or a section has failed and you no longer have access to the full memory. Continue with the process but I do not think that you will be able to recover the partition.

dailyroach,
Just some info on why this may have happened. All chips when manufactured contain errors and bad cells this is quite normal. Chips are batch tested for quality, batches with minimal faults go for the highest price and are the most reliable.
Batches that return poor test results are sold a lot cheaper and are more prone to failure. As you can imagine the manufacturers of these players look to produce them at the lowest cost they can. They are not intersested in quality.

All memory degrades with use and will finally fail after many 1000's of read write operations, with poor quality chips that already have an abundance of bad cells and weak spots this can happen a lot earlier.

Re: Wanted : Hacked chip recovery testers
 

i think you are right i may have lost 3/4 of the chip in some way this may account for the lost size i think i will just use it as a 512 now as it is stable at that thankyou for all your help ...

Re: Wanted : Hacked chip recovery testers
 

I just got a new MP4 from China last week and the space back then was 998Mb. I was manage to use about 47% of that space before i use the MP3 Player Disc Tool to Format and then later do the Partition and Encrypt. After the Partition and Encrypt, my MP4 space was reduced to just :cry: 233Mb :shock: Is this also one of the conditions all of them that are having here? And i've already tried with the TestDisk procedure in page 1 and still getting the same stuff. :wink: The question is : Why am i still able to use 47% out of 998Mb which is around 470Mb if the real space in the MP4 i got was 233Mb? :roll:

Re: Wanted : Hacked chip recovery testers
 

i had a problem like that!
When i use mp3 player disk tool! my mpx 4gb changed to 108 mb! Help me to solve it!

ctht, Check your players settings and make sure that you have Online Mode set to Normal Only. I am unsure why you are still having different readings but if you want to know the true size of your memory chip then you will have to open your player and check the chip serial number. You can check Samsung and Hynix chips here
http://www.mympxplayer.org/samsung-a...rs-vt1692.html

cardinalbird, I would say your chip was hacked to read 4GB and the true size is only 128MB. Check the memory chip serial number here to find it's true size.

Re: Wanted : Hacked chip recovery testers
 

Well, took me some time to remove the sticker that was stick onto the chip and the number in it was K9F2G08U0M from Samsung... By comparing this to your list it would be 256Mb.
Ok, i can accept this FACT that i've been cheat with the Space of the MP4 but doesn't borther me much cuz i get this MP4 for free.

And cardinalbird, hope you get your 4Gb back cuz it would be devastating comparing the ratio of Memory Space lost due to the hacked chip with mine, 1Gb - 256Mb and yours' is 4Gb - 128Mb... :?

ctht, The worst I have seen is a member who ended up with a 64MB.

Re: Wanted : Hacked chip recovery testers
 

64?!?! They still producing chip of that size? :shock:

hi! Tadad1!
i have a problem! i want to have tutorial from U to solve it!
I did with your tutorial for dailyroach! and here my backup file

#1162874829 Disk /dev/sdb - 106 MB / 101 MiB - CHS 13 255 63
1 : start= 63, size= 221949, Id=06, *

I don't know why my mp3 don't recover his size! help me, please!

cardinalbird, You need to open your layer and check the memory chip serial number to find it's true size. My guess is your chip is only 128MB.

You can check the serial numbers for Samsung and Hynix chips here:

This is my problem:

my player shoulb be of 1g

but I´ve never been able to charge that amount of data.
at the beggining It appear on the computer as two different disks, I loaded the files in the one I could enter, cause the other one was with no format.
Half of the files I loaded worked right but when I tried to play the other half the player rebooted itself.
"how misterious!" I thought
then I started to delete those files that were corrupted (at least that`s what I thought!) but I could not.
How strange! I thought that time.
Suddenly without advice windows let me delete the files and I left the player empty.
I load songs again.
And something even stranger happened in one folder (the "record" one used to save the things you tape with the player) were all the songs again and again and again, it´s hard to explain, but I thought, IT MUST BE A VIRUS! EUREKA! so I decided to format the drive ... now the displays says that my memory is of 474 MB
Is it hacked? or I did something wrong?
when I use the encrypting tool it says that the memory is of 474 MB too
but before it said that it was of 969.780 MB (something like that)
anyway it´s a crap, can anybody tell me if this testdisk can help me?

to be honest this player is quite a headache

Tadad,

I have a mp4 2G that I tried to use your test disk tool on but when I tried the program it said the drive was not the correct size (or something like that).
I then used the tool in the 4.00 amv convert program ran the slider from full left to full right, repartitioned and then used windows to reformat in FAT mode. Well guess what my 2G is really a 1G! Not as bad as others here have been scammed but still a bit of a bummer. I then opened the case and confirmed the samsung # K9K8G08U0A chip is installed. I have a few more units on order from ebay and I hope they are no worse. Thanx so much all you guys for your hard work and efforts to help us all. It is greatly appreciated!

Is anyone getting true 2G players off of ebay?

Dave

Hello, Dave

My name is Elizabeth I work for thedigiword LLC in the usa. We have 83 models of mp4 & pmp players as well as Apple samsung and others. We sell wholesale and retail at the best quality and price. We are new to online sales so our website is not up and running yet. But We have just opened an ebay store http://stores.ebay.com/the-digi-world . thedigiworld LLC. looks forward to working with mympxplayer.org in helping with the progress of these players.

Hi tadad1

On reading this thread, I am a litle confused! I have bought 3 of these 'bogus' players from eBay sellers and there is something wrong with ALL of them. :oops: One of them shows up in Windows as a 4GB, but it corrupts everything above 1GB (980MB to be exact!).

The seller told me to format it as FAT and not FAT32, is this correct? Also, I have not had any usable utility disks shipped with these players (either they don't contain the firmware or they are corrupt and the only thing they contain that works after a fashion is the video conversion software).

Also, they are supposed to read TXT files but all I get is a file (with a readable filename), but the text is jibberish?

Also, one of the batteries is completely dead (so I am unable to tell what capacity it is), is there any way to change the batteries for these players and if so, where do I get one?

Thanks for all your great help.


I'm at my wits end with it all and wonder if I should have paid the price for a Sandisk Sansa!

Hi avionik99

I don't think so, check out the thread on this forum http://www.mympxplayer.org/viewtopic.php?t=1323&start=0

Hope you don't encounter the same!

hazel7797,
The 4GB that corrupts over 1GB is most likely a 1GB.
Fat format if you can, hacked chips sometimes will not let you format in Fat.
The MP3 Disk Tool is part of MP3 Player Utilities which also contains the AMV Converter.
You will find several versions of the utilities in the Downloads>Tools section.
I have replaced batteries in 3 players with iPod replacement batteries all run perfectly fine with hugely increased playtimes. You are really governed by what size battery you can use though. I have seen replacement batteries for nanoclones on eBay just do a search for "MP3 Player Battery" and they will come up.
I am not sure why you are having problems with your text files. Have you tried creating a short sample in notepad and see if it works.

Thank you tadad1, I have since found your, How To - Removing Memory Hack' and have followed the instructions, my results are: 1 x 4GB player was actually 2GB player, the 2GB player was 1GB and the worse one was a 1 x 4GB player that was actually only a 1GB player!

It also cleared up the txt file problem - I can now read txt files OK!

I will look out for batteries in the hope that I can redeem something out of this awful situation. At least it isn't guesswork anymore and I know EXACTLY how much music I can put on them without them being corrupted!

Thank you for all your help. xx :)

Re: Wanted : Hacked chip recovery testers
 

Hi
Just wanted to report my success. My heart sank :cry: when I first realised I had been ripped off, but I dilagently read through as many posts as possible and now thanks to testdisk 6.4 I have a fully functioning 966mb MP4 player.
First I backed up the firmware with s1fwx (in case of self induced disaster)
then ran testdisk 6.4 then disk tool
My players firmware is 9.0.4.3 and testdisk did not effect it in any way.
I am still a bit grumpy about how long the battery lasts (2hours), but hey, some folks don't even get 5 mins out of their battery if they get any life from the player atall, so I should not moan!
Anyway it prety much works like a dream now, and whats more I have negotiated a refund of 60% :shock: in addition to keeping the player, so all in all it has worked out o.k. :mrgreen:
TESTDISK 6.4 is brilliant!!!!!!!!!!!!!!!!

Re: Wanted : Hacked chip recovery testers
 

Hello, the FAT32 shouldn't be used in 2GB or less partitions because the size of clusters, the clusters in FAT32 are bigger than FAT therefore they compsume more memory in system data.

regards from Colombia

I recomend to you use the TestDisk to remove all partition data, then use the MP3 Player Disk Management Tool to make a new partition, and then use the formatting part of these tool to make a Low Level Formatting of Disk.

First you can disassemble your player check the number in Memory Chip and then go to http://www.mympxplayer.org/samsung-a...rs-vt1692.html and check the true capacity of you chip.

Re: Wanted : Hacked chip recovery testers
 

Hello, the firmware in player is loaded in the same memory chip used to store files.

when you turn on the player the firmware is loaded by the bootloader (is when the screen become blue with a sand clock) then the firmware takes control of memory and the space not used by it self is released for by used as a hard disk, when you plug the player en USB Port the firmware use a standard protocol to tell to the operative system of computer what the device is a mass storage device then the operative system of Computer treat the device as a hard drive and when de OS make a partition, MBR, boot sector and FAT on it become a disk. because that you must not be able to clear fimware using a disk utility, because the firmware self protect making the part of memory where him reside "invisible" (that is because if the memory is 1GigaByte you only see Aprox 950 MB).


There is another thing called "bootloader" must not confused with the bootsector. the bootloader is the program which load the firmware as the BIOS in a PC, this bootloader is in processor chip. if you read the recovery dead player guide you must make a short in the memory chip for the processor's bootloader can´t recognize the memory chip and then goes to ADFU mode making possible recover a dead player.
