[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Tkkg1994:
Q&A

Below I added some basic Q&A stuff which here so hopefully it will answer most of your questions!

Q: How to get into Download Mode?

A: Power off your phone, than hold: home + volume down + power on button until you see the download mode.

Q: How to get into Recovery Mode?

A: Power off your phone, than hold: home + volume up + power on button until you see the recovery mode.

Q: I get verification failed at start up!?!? My phone is broken now?

A: Yes, you have to buy a new phone now. Just kidding :D You did not disable force encryption in TWRP (how to do so you will find below in how to decrypt your phone).

Q: I get FRP LOCK? WHYYYYYY???

A: Very simple answer, you did not enable OEM Unlock in developer options. Now you need to flash full rom with odin again and start from scratch. But don't forget to enable OEM Unlock this time!

Q: I got FC's and other Problems with the kernel, what to do?

A: Take a logcat for me, developers use to say: without a log, it never happened ;). A logcat can be grapped with a PC and ADB installed, simply type: adb logcat > log.txt while your phone is connected and the error is happening.

Q: What kind of logs can I provide to help you?

A: Logcat: This one is for general infos about FC's

DMESG: this is for kernel related things

Last_Kmsg: this can be used after a random reboot

Q: How to get logs?

A: 1. Connect your phone to your pc

2. Make sure you got usb debugging enabled

3. Install Minimal ADB tool

4. After install open it and type: adb logcat > logcat.txt, adb shell dmesg > dmesg.log, adb shell cat proc/last_kmsg kmsg.log

5. Send me the file you got

Q: Which devices are supported at the moment?

A: Current supported devices are: SM-G930F/FD/W8. All other exynos models can work but are UNTESTED

Q: Is this kernel working on Snapdragon 820 variants?

A: No, sadly not.

Q: Help, I never had a code and now after installing the rom my phone asks for a password??

A: Your device is still encrypted, on step 0 it tells you to be sure you're not. So, what do you need to to in case you are still encrypted:

1. Boot into TWRP

2. Select Wipe

3. Select wipe data

4. Then you manually need to type "yes" with the keyboard

5. Confirm the wipe (this will remove the encryption)

6. Reboot your recovery

Q: Is there a way to get rid of encryption which is simpler?

A: Not really, you could also wipe data with stock recovery but this is quite a big hassle so above method works better.

Q: On TWRP there is an error about /data mount, what to do?

A: Your device is encrypted, follow the above steps to get rid of your encryption.

Q: Synapse shows no UCI support!

A: Reflash kernel, a script of you may overwrite my synapse config

Q: I want to switch kernel, how?

A: Since we have systemless xposed and systemless supersu, we have patches in ramdisk of boot.img. This means you have to reflash xposed and supersu after every change of kernel!.

Q: I lost root after installing this rom. What to do?

A: All mods (like supersu, phh's root, xposed and magisk) are stored in /ramdisk of kernel boot.img. So if you flash this rom, and after this another kernel (Which has supersu included by default) you can not do much. You have to stick to the two kernels provided in rom. Also when switching kernel, you need to flash all related zips again after changing it. Last tip: Do not use magisk until you really need it for android pay!

Q: I got random reboots, heeelp!

A: This is most likely from a custom kernel, if you face random reboots please check if you have the latest kernel installed or switch back to the stock kernel included in the rom.

Q: My screen is kind of yellow/orange and the touchscreen doesn't work at all!

A: You have chosen the wrong kernel in aroma selection. Reflash the rom without any wipe selecting the right kernel version.
