Problem with NAND storage on RK 312x



Being my first post on this huge place, I wanna thank all of the people that stands here and provide help support and wisdom for all of us who are new on the site, AND in the scene.

That said, my need:
I have a Tablet PC running 4.4.4 kitkat android device, with 312x rockchip processor, 1 gb ram, 8 gb rom, usb and micro usb, mini hdmi, bluetooth and wifi connectivity. I wanted to change the internal storage capacity, since like all chinese tablets, haas a 1 gb (0.98 gb to be precisely) and 6 gb of nand storage (5,28 aprox, i cant remember now, you will see next why). I wanted to change the parameter file so i can gain more space on the main storage (where apps are installed, as you may know), but there was no change. Suddenly, after a few tries, when it finished the booting process, now running the kitkat, in settings appear that the nand storage cannot mount, and every time i try to do it, it fails as it says "the nand storage can be safely removed". Now then, i have a 0.98 storage in the system, but no nand storage, so i cannot install nothing to the nand storage. I installed TWRP generic rom but for recovery only, and it works, but since the nand seems to be corrupted, i cannot modify at all nothing.
To modify the parameter file i dumped the entire rom of every single part of the tablet: system, kernel, cache, etc. With parameter file in hand, i used an hex calculator to modify values and gain the storage i needed (3 gb in internal, whatever it left to the nand storage) but nothing happened. Could the nand be corrupted? i still have the roms and the parameter as it was installed, tried to reinstall via batchtool 1.37 but there was no change.

Any help will be welcome and support will be thankful.
Thank you for reading this.



S3 NAND Fail



Hi! My rooted S3 started to reboot randomly and suddenly one day stopped working. It's stuck on the "Samsung Galaxys3 GT-I9300" screen. I'm able to enter download mode and recovery mode. I can't use factory reset/wipe data because as soon as it starts the phone reboots.

I've tried several guides to no avail, I just can't get it to work. Kies can't see the phone, but Odin works. Even tried cleaning the power button just in case, but I think that only works for the samsung logo loop. Last thing I tried was a "GT-I9300XXEMG4_KOR_MULTI_FACTORY". This is what happens:

I'm at a loss. The phone worked flawlessly (rooted) for more than a year and suddenly this happens. Maybe when the random reboots started I could have done something, but what's done it's done. I've read that I could try changing the motherboard, but they are kinda expensive for something I don't know if it will even work. Tried different computers, USB cables, but it's always the same. I remember I had the avast anti theft app, but I don't know if this is what's preventing me from wiping the data or fixing the phone.
