Real firmware needed
 

Hello. I have bought an mp3 like nano and it had to be 8gb. I noticed that windows format tool works great, but it still has errors on playing all the songs when it's fully written and songs can not be normally deleted, just over windows format tool, mp3 tools program is nor working with this player and I did h2testw test which shows that it's about 4gb player. I opened it and found out this info:

Hynix H27UBG8T2ATR
BC 051H

And other chip is AK2027C

MP3 shows that firmware version is:

CBD CO., LTD
2010-09-27
9.5.60

Could you give me information, how to fix this player back to it's real memory? Thank you very much.
