[Q] Tablet is acting strange

[danizmax]

Hi,

I've been using galaxy tab 8.9 with custom ROMs for more than a year and a half now, and sometimes it was acting strange, like flickering dialogs and crashes. Usually this meant an unstable ROM or just cache wasn't cleared when a new ROM was installed. And it was stable for some time, till I did a reset. Now no ROM is stable any more in addition to this, the battery sometimes says it is empty, but after restart it is back to normal status. I tried number of ROMs without luck, all are flickering lately which must mean it is not ROMs fault.

I am running out of ideas what to do with this tablet, so I'm asking if you guys have any suggestions, what else can I do to fix it.

NOTE: when installing a new ROM, I always did it with CWM recovery from internal storage with data, cache, dalvik wipe and factory reset.


regards, Daniel

Do you ever wipe the system partition?

Do you ever wipe the system partition?

Agree. In TWRP, a factory reset only wipe data, cache and dalvik cache. You have to manually format system. A clean install requires to wipe system, data, cache and dalvik-cache.

Try flashing the original firmware via odin.

Try flashing the original firmware via odin.

Flashing original firmware would be my last resort. Is there any difference between odin and CWM flashing?

Of course. Flashing original firmware via odin brings back the original setup that came with the tab out of the box. I just don't remember if it will delete the contents of internal sd card. In any case, you can flash original firmware thru CWM as I always do, though I only flash boot and system images I modified in Kitchen. It will still be stock but only that it has been debloated, rooted, busybox installed, init.d enabled, and some system apps replaced.

Just remember that when flashing ROMs via CWM do a factory reset (wipe data, cache, dalvik-cache). In addition to the wipe, the rom.zip itself formats the system partition prior to flashing.
