I know that a previous post of mine talks about the infamous eMMC problem where the chip will burn out, however looking over some of my notes on eMMC chip problems I did come across a couple of things I noted in regards to possibly finding a solution to a couple of the issues.<\/p>\n
\u00c2\u00a0<\/p>\n
Now the usual way we know we have an eMMC problem is that we get:<\/p>\n
\u00c2\u00a0<\/p>\n
E:Can’t mount \/cache\/recovery\/command<\/p>\n
E:Can’t mount \/cache\/recovery\/log<\/p>\n
E:Can’t open \/cache\/recovery\/log<\/p>\n
E:Can’t mount \/cache\/recovery\/last_log<\/p>\n
E:Can’t open \/cache\/recovery\/last_log<\/p>\n
\u00c2\u00a0<\/p>\n
appearing as a debug message, this is actually the full “cache” partition being corrupted. Obviously the majority of rom chefs have run into this problem many times and myself included I have seen that message on more than one occasion over different handsets.<\/p>\n
\u00c2\u00a0<\/p>\n
Usually there isn’t a fix for any error like that, once the cache partition is corrupted you really cannot recover from that, it is a catastrophic failure. The only way I have been able to fix this a couple of times and that was by\u00c2\u00a0immediately\u00c2\u00a0removing the battery and letting it sit for a couple of minutes before putting the battery back in.<\/p>\n
Then if you boot directly into the boot loader and hit into recovery mode.<\/p>\n
Now if you haven’t received any major errors you cahce partition should now be formatted as ext3, so if you cycle through the menus and format it to ext4.<\/p>\n
Do a full wipe of everything, including factory reset, davlik cache and battery stats<\/p>\n
Flash the rom of your choice again (now make sure it is the correct rom for the phone) and hope for the best that it works.<\/p>\n
\u00c2\u00a0<\/p>\n
Now hopefully that potentially can resolve your problems, if not then you will probably have a serious eMMC problem and potentially will have bricked your phone.<\/p>\n
\u00c2\u00a0<\/p>\n
I will say this method has worked 9 out of 10 times with me and I still have these notes saved for the next time it occurs.<\/p>\n
\u00c2\u00a0<\/p>\n
Key things to remember, always track changes in the rom – see if there is a good user base and check them against other more popular roms to see the differences and benefits if there are any.<\/p>\n","protected":false},"excerpt":{"rendered":"
