PROBLEM

So far, I noticed that after I turn it on and it completely loads up, it can't:

  • show notification-bar
  • use camera
  • detect or recognize "internal USB storage"
  • detect or recognize "SD card"
  • use WIFI (when clicked, just says "Error")
  • sometimes use cellular network (have good signal strength but can't reach the network)
  • sometimes detect "SIM card" (PIN asked on booting but on settings page can't detect!)

WHAT HAPPENED

My device is pretty heavy on apps (about 200 apps installed), sometimes while I`m working, it hangs and everything just freezes but after about half hour cellular network automatically forced to turned off and everything will be just normal and after reset, net will be back too but the last time that this happened, it took about two hours and when I reset the device, my problems began.

WHY

I think all of this is happening because of two reasons:

  • the Operating System kernel drivers maybe damaged
  • hardware failure (maybe some IC controller fried!)
  • because device can't detect internal/external storage so many apps (such as operating system's own apps) can't work properly

DEVICE INFO

  • Model number - Samsung Galaxy Mini 2 (GT-S6500D)
  • Android version - 2.3.6
  • Baseband version - S6500DJPLI1
  • Kernel version - 2.6.38.6-1206137
  • Build number - Gingerbread.JPLJ1
  • Status - Rooted

P.S.

I know that I simply can use Android's Recovery mode or Odin for flashing a new Operating System but I don`t want to wipe all of my data (very important to me!)

200 apps on Gingerbread :O, time to upgrade now. Even on my OnePlus One with 3gigs RAM and 64gigs Internal Storage, I merely have 20-30 downloaded apps with 2-3 in start-up.

But anyhow, follow this:

  1. Format and install some custom ROM like Cyanogenmod
  2. Keep only required apps.
  3. Remove apps from start-up. Use AIO Toolbox from Play Store.
  4. Use AIO Toolbox on regular basis to clean up.

For all your apps backup: I believe in that list of 200 apps, you must have some system tools. Check if it has backup option for apps or not. Even you can create backup from recovery mode too, if your recovery supports. TWRP/Cyanogenmod/ClockWorkMod do have this option.

as you quoted:

I don't want to wipe all of my data(very important to me!)

So, A way to do this would be backup editing. You will need the following:

  • A PC
  • Your phone, rooted, with cable
  • adb installed (intall from here)
  • a copy of the stock ROM from online(you made need a MD5 dismantle method, look at this link here

Assuming you are not rooted, do this first: download kingo root from here and install it on your phablet. Then, press root and wait. Once it's done, continue on below.

If you do not want to root (even though half this process will unroot it) look at the answer here

First, turn on your phone. head to developer options, and enable USB debugging. Then, plug you phone, and use the command 'adb root' to ensure no problems, or very few anyway. adb pull / backup.zip (leave a space between the source i.e. the /, and the place you will save it) Be sure to to put what you want to save it as.(I suggest backup.zip) next, with the stock ROM, take it apart (see link i gave you on how) and "loot" the /system file. Then, open the backup you made, and replace the backups /system with the stock /system. re-zip the modified backup, and boot your device into recovery. from recovery(must be custom, 2.3 does not have what we need by default) choose an option along the lines of install update via sideload,then run this command on your PC: adb sideload <filename of update.zip> or, in this case:

adb sideload backup.zip

And wait. By the time it reboots, it should be in fine condition, without the loss of your data. Good luck :)
