Camera Issue Final Fix (Updated TWRP & Custom Kernel to New Base)

As mentioned earlier, third party selfie camera for third party app was broken on Q10 because of lacking of TWRP & Kernel from latest source code. Now it is available and posted in Download area/Q/N975F_N976B_N976N/Root_TWRP/

All Q10 users of N975/6 requested to flash above said TWRP & Kernel after flashing Q10

After this fix, you will have latest TWRP & Custom Kernel & no more required to use combo key to reboot to system with root.

Q10 for N970F Will be available in few minutes (untested). N970F already have included new kernel, N970F users needs to flash newer TWRP & Kernel just before flashing Q10, and no needs to flash after flashing ROM. N970F users needs to update bootloader & modem if TWRP showing black screen only.

hey dr. where is the fix? I cant find it, is the download area is the one on your site "download rom'? if yes there are files for android 11 and 12 but im on android 10 Q10

also , on S07 with tweaks pro , secure folder works?

thank you for the hard work

well then I'll say it, this is the only ROM that can be used flawlessly on this phone (N975F) on the entire XDA, it's a pity! the phone itself is almost flawless and I'm not willing to replace it yet, but for example magisk can only be updated if I replace the kernel? why is this

Important Instructions for setting up ROM (NEW)

- In case clean installing ROM
  • On first boot, Check for Magiak app, you may needs to update stub/Install apk manually. open magisk and complete the additional setings if asked for, else exit the magisk app. (Don't setup any option in magisk now)
  • Then open ROM Tool, Apply essential fix and Reboot

(ROM Tool Essential fix also give option to install this app) There is separate SafetyNex Fix option available in ROM Tool - Mods & Misc fix - SafetyNet fix, You can use anytime if needed.
  • Now you can further setup ROM a per your liking. Also MagikHide is Configure Denylist now and available under Magisk Settings.
  • Since A12 Stable Magisk not working and new Magisk doesn't have buil-in Module repo, You can get standalone module manager from here For more details and queries about new magisk ref this (ROM Tool Essential fix also give option to install this app)
- In case dirty install (You can try if you are on DrKetan ROM previous version but we DO NOT RECOMMENDED)
  • Clear ROM Tool data
  • Before installing ROM, uninstall Magisk manager from app drawer
  • After ROM installation, update Magisk from installed stub
  • Then Follow above instruction for clean installation
  • In case you have any issue after dirty install, don't post queries on thread, we don't support dirty install, simply go with clean install.
PS : Plz don't install any other mods for SafetyNet, All queries related to Magisk/SafetyNet will be ignored if already explained above

  • If you are on A11 and updating to A12, we recommended to flash Stock firmware once, If not full, at least download your regional A12 stock firmare - Extract Home_CSC*.tar.md file and flash using Odin ith CSC tab. Also it is better if you flash CSC everytime flash updated version of ROM.
  • New base have updated bootloader so if you are running previous base, you must needs to update Bootloader & Modem else device may not boot. BL and Modem available in download area
  • Included DrKetan/Cruel kernel which is compiled with source code from cruel-kernel Thanks and credit to @ evdenis for kernel. Here is OP for kernel & source code
  • Clean Install is recommended always.
  • Don't Install any module related to SafetyNet Fix/Busybox/Multidisabler etc, Everything is included in ROM itself.
  • Magisk is built in custom kernel, SO DON'T update/flash magisk, else it will cause bootloop, In case this happens by mistake, re-run ROM zip, skip everything but Flash kernel and finish installation.
Important notes for N976B/N
  • This ROM is fully Single ROM for N975F and N976B/N and N970F ,While flashing ROM, N976 must select N976 kernel from aroma.
  • N976 may have network only after Applying ROM Tool essential fix + Reboot. ROM Tool will detect device and patch it accordingly.
  • We do not support dual SIM variant of N976 device, So you may have only one IMEI after setting up ROM. Some users reported Dual SIM working if you manually add Access Point for it.

I recommend clean Installation only. If you are able to handle consequences with dirty flash then proceed, but don't post bugs in forum without clean installing ROM.

I have had this issue too, never notice as I don't use air action so keeping air action toggle off.
When ever I enable air connect it aways show fluctuating 10% to 100% and using air action, getting disconnected in few second
- Updated bootloader (before that it was not updated)
- Deleted data/misc/Bluetooth and data/misc/bluedroid
- blown air in spen room
- reset s pen from air action-three dot

Now since 30 min it works as it should and charging 100% and discharging normally after using air action
S07,having this issue,i followed the instructions ,except updating bootloader since its updated from the latest files that you provided in download area ,still the problem persist

edit:I now also flashed the bootloader + modem that you provided , and followed the steps again , the issue is still occurs

Dear ROM Users
Before you expect too much with this ROM, let me say,
Routinely I support device 2-3 yrs, but here Its been about 4 yrs started N10 project and hardly skipped updates and that too lately in last few months. Now it's time to end. Though I am planning to release last version of ROM (probably with April update itself) and that will be likely with Magisk 25.2 only (uness can fix some Magisk 26+ issue on N10 devices) But I can't promise if any future version will release or not.
My sincere thanks to all users for amazing support & showering lots of love with this project
Again Thanking you all.
hi master doctor.on how meany days its out? the last version of ROM..and thnaks for 3 years best rom for note 10+
