T94 mtk6589 bootlooping due to DPI change.
Hello to all.
I bought recently a Tengda T94 (also being referred to as Dapeng T94).It has MTK6589 chip.
Me,the smartass,wanted to change the DPI setting of the smartphone,because Real Racing 3 lagged a little bit and thought changing it might fix the framerate.I changed it from 320 dpi to 221 with LCD modder and reboot.Then the surprise struck me,when it didnt start,it just stood on the logo and kept replaying it.I have tried with ADB commands - some works,some not.
I am with stock recovery 3e.
Has only few commands like reboot now,install update from adb,cache,sd card and wiping cache and another option for wiping data to factory settings (and two irrelevant options of restoring/backing up user data).
I tried wiping all data and cache,still bootlooping.
Tried with mediatek firmware adapter tool,but i think it cannot change the build.prop file while bootlooping (it cannot find my device when in recovery mode),because it is either in use,or in read-only mode.
Tried with android commander,but didnt know what to do there.
I downloaded rather late a CWM recovery for my phone,and also if I am not mistaken two roms - one of them is exactly like mine.
But when tried to install thru recovery adb sideload it starts and then says : restating ADBD ....... installation aborted and returns me to main recovery menu. Tried with my backed up build.prop which i have put in flashable zip file.
However,the two roms i have downloaded arent working properly.They are zip,but still adb sideload cannot read them.
And another (i dont know if it is relevant) my external sd card 16 gb default,when i put it in my old gsm to put the two roms and cwm recovery files,first windows wanted to format it and the only option was FAT 32,total of 2.87GB.What has happened to my sd card ?
Still I couldnt install from the external sd card the roms,only zip with build.prop file was listed and gave the same mistake as said above : restating ADBD ....... installation aborted.
PP: I have arrived at the conclusion that the problem is this line ro.sf.lcd_density=221,which is in build.prop file (I might be wrong).So the question is can i somehow modify the prop file or what should i do ?
And why has my sd card shortened from 14,6gb to 2.87 ?
Sorry for the long post.
