Fix charging on a N9300 (chinese Dual-Sim Variant of Note 7)

[zroice]

Hey guys i was wondering how to fix the charging on a n9300?

Where is that charging block located in? Kernel, System?

And is there a fix for the N9300 at all? All the roms are for N930F or N930FD only.. =(

Hi. Yes it's located in the kernel. You need to flash a custom kernel with twrp for your note 7 variant...

Are there any "fixed" kernels for the N9300 (TGY) variant? Otherwise ill have to try downgrade to older odin firmware and then disable OTA - but a custom kernel would be safer and better I guess.

If you get 60% update you can downgrade to 100%. If you get the 30% and less update, you can't downgrade anymore...

ok, damn i think its the 10% update.. any idea if there is a way to get this back to charging?

Maybe downgrade through TWRP?

Yes you need to flash a custom kernel based on 100% kernel or flash the original 100% kernel with twrp. Maybe you need to extract it from 100% firmware. I don't know how but it's the solution. Good luck

fml **** doesnt take twrp anymore.. says i have to unlock it but i alrdy did.. guess its blocking odin =(

flashing the boot.img directly (in a tar archive) doesnt work either.. fuuuck

EDIT:
...... ahh my bad didnt read about that crom service crap. got twrp installed now!

EDIT2:
flashed old boot.img but **** is blocked .. aka doesnt boot - sigh such a pain in the ass

Odin won't work anymore with you. Downgrade is blocked by Samsung. The only way you have it's installing from twrp...

yea i flashed it through twrp but its bootloader blocked apparently..

I found some chinese custom rom for the thing but its downloading with like 10kb/sec .. so next week ill know if that works.. =)

the story continues... now i have a chinese custom rom on the n9300 and its charging and all.. but gapps dont work =/

They were not preinstalled and i flashed the latest version for 6.0.1 and arm64 from opengapps.org, but somethings not going right. Google play services crash occasionally and after sign in i get booted out of the play store to reauthenticate. Im guessing there is some block in the chinese roms .. =/

So my only hope now is to flash a hongkong version again (which would return everything to stock.. means doin it all over again and take the kernel from that custom rom - with that the charging works at least. The older kernel from the old stock odin version didnt boot as I said.

Or any ideas on how to get the gapps running? Tried removing the play services in hopes that the store would just load it after setting up but then the store doesnt even open anymore =/...

Endless story this heh.

hi @zroice, did you manage to make this work? I am exactly in the same situation that you have been in, would really appreciate your help.

Install the hongkong version, that comes with google play. If you cannot charge then you need to try to downgrade.

If you cannot downgrade with odin because its blocked then you need to download aurora chinese custom rom for n9300 (google is your friend for that) and extract the kernel (boot.img).

Unlock bootloader, flash twrp and then that kernel from the aurora rom (through twrp image flashing on boot partition).

If your device then does not boot into the system anymore because "you are using an old kernel" or something then you need to extract the system.img.ext4 of an older hongkong odin rom version and copy that onto the phone space.

With "simg2img" you can convert that system.img.ext4 to system.img in adb shell terminal and then as final step flash that with "dd" onto your system partition (should be sda21 iirc). then it should boot and charge when you get the right system and kernel combination.

Its not trivial so pls understand that if you cannot follow these steps or dont understand then you better shouldnt do it, or find some android expert to do it.

PS: If you dont need google play or wanna try to get that running on the chinese version (also has all languages, but no google and some chinese crapware) you can just try and flash that aurora custom rom for n9300.

Here's the link to the chinese custom rom for n9300 with fixed kernel:

Unfortunately you need to make an account at that site to be able to download - chrome with instant translation helps alot with this.
