MTK 6228 firm. problems

[godai]

I have a few of phones with this chip, and always when I try to read full flash say that the firm could be corrupted or damaged.

I try to open these extracted firmwares with lp editor and it says that no lenguages were found and that firmware could be damaged.

What could I do?

Thanks

Hello,

Try to read flash at low baudrate.

hello!

firmware readed with errors. this is why you recieving this error.
might be damaged hardware which cause phone unstable work, which gives errors while reading

the phones I tried were all without problems, just wanted to extract the firm.

I will try to extract at low baudrate and post results.

Thanks

There is no way. I use low baudrate (not lowest) and always firm or flash damaged. Here is the log of one of the phones I have with mtk 6228:

Am I doing anything wrong?
