I can see the sn.txt serial file error, is this what problem cause is? do i need to make new serial everytime i re-burn?

again, i try using sd card booting ubuntu mate, still seeing 1gb ram instead of 2gb…what is wrong??



Hello,Did you mean the original ram IC was broken? and you have replaced new one,but the Board doesn’t recognise it,right?

yes, sort of like that. The ram ic was broken, so i solder new one into it. The board can boot fine no problem it look like at least…just the ram size is not 2 gb. Board was send to me in good condition, 2gb ram, but I use in my project and broke the ram. Any advise??

Hello,could you make sure that the ram ic you replaced is 2Gb size? could you provide me the datasheet?

or could use the original same type ram ic ?

ok, i think i made a mistake reading the ram ic number. I read H9CCNNN8JTML, when it was suppose to be H9CCNNNBJTML, the latter is only 1Gb density. I found out today, I will order to replace with the same ram ic and see what happens.

Ok, now I have install new Dram, i can boot and into android using both SD-Card and internal EMMC…I have new problem with the EMMC part.

After I have boot new the 2Gb sdram…using android V5 in internal emmc, after running a while, I begin to get crashing. After android crash, not running anymore…cannot boot. I think i reflow correctly the sdram and not touching the emmc flash chip…

So , I heat the emmc chip again and voila…it boot again…after about running 1.5 hour…it crash again… This problem repeat everytime i reheat the chip, boot, crash and reheat the chip…what is wrong here?? very frustrating problem…

Any idea?? is this hardware problem…or emmc chip defect/broken? or something else is wrong?
