Hey guys,
So, many of you have probably heard on one forum or another that there IS a was to root (and brick) your phone. Bricking occurs when the "/system" folder, also called the system partition, becomes wiped! One will realize this when they boot their phone to find that the G'zone is not actually, "now loading". However, thanks to the user monkeytools, this "bricking" can be overcome! All that it requires is a windows computer, 32 or 64 bit. However, I do not own Windows 8, so for the drivers working on that, i wish you luck If it does not work, you could build a vm of windows xp or 7...
This process is good for users who:
A. Want to develop system ROM's/Updates
B. Want to have a fallback in case they become 'curious' of the file system
C. Do not have, or have an expired, warranty. And most importantly,
D. Those who want ROOT!
There are several instructions that must be followed in order for this to work. If you are not sure about a step or process, it is best to not do it, and ask first.
OK, now to the juicy stuff!
1. The first thing to do is download the unbrickable phone toolkit. And read the readme.
2. Install the adb drivers. On your computer, install the drivers.msi file that came with the toolkit. If it gives you an error about the phone and being connected or not just go to task manager and terminate the process.
3. Go to your C: drive and make a folder in the root directory called "sdktools". Copy and extract the toolkit's files directly into that folder. The filepath should then be "C:\sdktools"
3.1 Select your boot.img version. info is in the readme. Rename to boot.img and place in the sdktools directory.
4. Check to make sure that the adb works properly. On your phone, go to settings->applications->development. If the box for enabling usb debugging is not already checked, check it.
5. Plug your phone into your computer, and set it to charge only mode from the usb notification. There should also be a notification about usb debugging on.
6. Verify that the adb and usb drivers are working properly. On your vista/7 computer, press the windows key, and type "device manager", and click it. On 2000/xp computer, go to start->control panel->system->hardware tab->device manager. I hope you know how to on windows 8 . In device manger, there should now be a "CASIO C771 Android ADB Interface" device, under android phone category, and a "CASIO C771 USB Composite Device" under "universal serial bus controllers" catagory. If one of both are missing, then it is due to the temperamental drivers. Use IObit Uninstaller to remove the drivers, the do the powerfull scan, and then reboot. Try installing the other drivers "from some random guy" and see if they work any better.
7A. Disable fastboot security, a.k.a. enable bypass booting. This is when the really dirty work comes in! Plug in your phone to your pc if you have not already done so.(Just checking) On you phone, go to the dialpad and put in "##program". SPC is 000000. Go to the Bypass Boot option, and enable it. It will say, "saved". After you back out of the program, the phone will then reboot.
7B. When the phone is done rebooting, reboot into the bootloader. To do this, after your phone is done rebooting, type the following:
cd C:\sdktools
adb reboot bootloader
the phone will reboot, and then get "stuck" on the unlit g'zone logo. This is good.
8. Verify that the bootloader is recognized on your pc. Open device manager. There should be a "CASIO C771 Android Bootloader Interface" in the same "android phone" category.
9. Flash the boot and recovery images to the phone. On the same command prompt from step 7B, Type the following:
"fastboot -i 0x0409 flash boot boot.img"
(text should appear about how it was sucessfull.)
"fastboot -i 0x0409 flash recovery recovery.img"
(again, same text should appear, but for recovery.)
"fastboot -i 0x0409 reboot"
(the phone will reboot with the new recovery and boot image.)
Those who wanted the boot.img update, you are done. Those who are in for the whole thing, your not quite done yet.
10. Reboot your phone into the new recovery. When the "CASIO C771 Android ADB Interface" comes back under device manager, type, "adb reboot recovery". Congrates, you now have a custom boot.img and recovery.
11. From the main menu options, make a nandroid backup of at least boot, recovery, and system. The others are for your own choosing. To navigate the recovery, use the volume up and down buttons to go through the menu options, and the physical menu button to select. The physical back button goes back.
If you are not rooted,from the menu options, go to developer menu, and select the 'install superuser and su' option. CONGRATS you're rooted!!!
12. Reboot your phone. Now, your phone can be recovered if the /system is wiped on it, using adb from the computer!
All I ask is that you press thanks if this helped you.
