Well Guys firstly my phone state:
1) Phone State:
*Volume down button doesn't work
*I can't boot into fastboot mode (may be because of above vol dwn button problem)
*My phone boots defaulty (and only) into safe mode
Hence, I can use only system apps.
2) WORK-AROUND :
I worked around this last week by rooting phone through Flashtool root section. Then I used adb to make all installed apps from playstore as system apps ( using adb shell su ..then shifting all apps to system/apps and then chmod to 644)
...and bingo all was fine untill I decided to unlock my boot-loader for future use...flashing custom OS etc ( I have no understanding of all these terms ..ROMs etc..Im quite a noob) :rolleyes:

ok so here's the start of my bad story :
I unlocked the bootloader using Flashtool....as my phone doesn't boot into fastboot mode by using hardware keys ..i used app "quikboot" which I had made a system app as said above....I booted in to "fastboot" mode using it ... then unlocked the bootloader ....and Then the phone went in bootloop .. I learn't that we need to flash stock ROM(for me ROM = mobile OS) after unlocking bootloader..so then I dowlaoded an older version of generic sony xperia M ftf file from xda...
Before flashing it I relocked the unlocked bootloader :eek:
I updated the OS to latest official. Due to the hardware problem the phone again boots into safe mode only for the newly flashed OS too

I tried to redo the "2) WORK-AROUND " section steps again:
When I try to " adb shell su " I get "su not found ..why does this happen ( I suspect because of phone not being rooted)..so I tried to rppt again using flashtoolas above..but this time while using towelroot phone reboots ( and hence the root fails) and hence I cant make those apps as system apps

So my phones up again but it locked, not rooted and I cant used any apps except the default Sony system apps(not even whatsapp gasp :( )

So I believe my only way out is to make installed apps system apps...for it that I somehow need to gain "adb shell su" working....Please suggest any alternative way around I may have ..
I really dont wanna change my phone ..its hardly been over a year only :rolleyes:

Bought a N-910S. That's what's floating around these parts, was a good deal, didn't think much of it.
But after the usual trip to XDA to find a good debloated, fancified Touchwiz based latest and greatest, I come to see ....
Not much of anything.
It's all 910C, 910H, whatever, but no 910S. Yikes. Yikes?!
What gives? Googled, searched, read, can't figure it out. No love for the 910S? Do I need to open my living room window super wide and throw this thing as far as I can? What will happen to the 5.1 update, and me-never-ever-getting-it?
Omg. Stop me from going crazy right now. Shed some light on this totally human life existential drama question.
