Basic 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: My Phone is stuck at boot and doesn't start, what to do??

A: Update your bootloader and modem. Also make sure you have made a fresh install of the rom. Bootloader and Modem can be found in the OP. Another problem can be that you are didn't decrypt your phone. To fix this read below how to disable encryption.

Q: Do I need to update bootloader and modem after every update?

A: It's recommend to update your bootloader and modem everytime there is a new base yes. The developer will tell you if necessary on every rom changelog.

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 verification 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: Which devices are supported at the moment?

A: Current supported devices are: SM-G930F/FD/K/L/S/W8. Snapdragons are NOT supported

Q: Is this rom working on Snapdragon 820 variants?

A: No, sadly not.

Q: I want to change something in my rom setup, how can I do that?

A: Simply reflash the same rom version without any wipe and than choose the correct things you want. :)

Q: Some features are not present in this rom, but they are on stock rom, so where are they?

A: In aroma installer you have the option to select bloat you want to install or not, you probably didn't select all package, this is why it's missing now.

Q: After a clean install my phone is overblated with many custom settings. What to do?

A: Open my romcontrol, grant it root permissions and then my default settings will be applied.

Q: Will you add X or Y feature?

A: You can kindly ask in the thread for that, if I like your suggestion I will think about adding it to the rom.

Q: You said you fixed SD card RW but Titanium Backup can't write to external SD card, why???

A: This is because of googles changes concerning SD card, to fix this open Titanium Backup, Menu, Preferences, Backup Folder Location, Storage provider and than hit DocumentProvider Storage and select your SD card. Problem solved

Q: I can't find X and Y mod. Please help

A: I've added many links and useful stuff to this post here. Hope that's what you have been looking for!

Q: I want to have my external storage like an internal as well. Google introduced it with android Marshmallow, but I can't see this option?

A: Just follow this Guide here and you can setup your SD card as normal storage

Q: I got a new strange icon appearing after nougat update. What's that?

A: This is a new advanced calling feature introduced in android nougat. Should make your call quality better or something like this. To hide it please visit following forum: Get rid of RCS icon

Questions concerning rom updates:

Q: Do I have to do a full wipe for the new version?

A: It is always the best option to make a clean install, otherwise please don't come and report bugs!

Q: But I don't want to make a full wipe when only small stuff changed!

A: For updates using the same bases you can install the rom with a dirty flash. BUT with a new base a clean install is highly recommend!

Q: What steps should I do to update to a new version with a full wipe but keep all data?

A: There are some different ways. One way is to make a backup with Titanium Backup, you can backup all Apps and Preferences there. Make sure to store this backup on external SD card (if you have one). Second way would be to save your data onto a google account or samsung cloud and restore it after a clean install.

Q: I miss an apk after rom update, how can I get it back?

A: Simply reflash rom and select "dirty flash" in aroma + select the app this time in aroma.

Q: My battery life is so bad and performance is very poor after an update!?!?

A: This comes actually not form the rom itself, dirty flash can cause problems even if only some small things have been changed. So simply install it clean again and it will solve your problem.

Q: Performance and battery is very poor even after clean install. What should I do now?

A: I assume you installed Xposed than, some modules can cause batterydrain and performance problems. So try to make a clean install of the rom WITHOUT xposed installed.

Questions about log and logcats:

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

A: Take a logcat for me, developers use to say: without a log, it never happened ;). A logcat can be grabed with a PC and ADB installed, simply type: adb logcat > log.txt while your phone is connected and the error is happening. Same can be done if you have a terminal installed on your phone. Simply type adb logcat > log.txt and you will have the same output as on the PC.

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

You can also send me a log created by your phones terminal with the exact same commands!

Questions about RomControl:

Q: None of my romcontrol changes do anything, why are you such a bad dev!?!?

A: The problem is not on my end, you installed stock systemUI (which is STOCK and does not support one single mod). Use another one in aroma instead. The same thing can happen with good lock!

Q: Romcontrol gives FC's to me. HELP!

A: Very simple answer here: wipe data and cache from superman control application. Also make sure storage permissions are given to the romcontrol.

Q: Romcontrol still FC after cleaning data and cache!

A: Make sure you allow storage permission in main settings.

Q: I try to backup my current RomControl setup, but it won't work?

A: It works. Just make sure to enable storage permission in main samsung applicatoin settings. You will find it in internal sdcard under RomControl folder.

Q: I can't restore SuperMan control settings after a clean base update, why?

A: Backup for SuperMan control only works as long as you use the same version of the app, I mostly change very much things in new releases that's why it won't work there.

Q: SystemUI reboot doesn't work in SuperMan settings app, why?

A: Since Nougat update, you need to install busybox in order to get this button working. Without busybox the button will just do nothing.

Q: I enabled weather on lockscreen but I can't see anything...

A: You probably didn't setup or even installed samsungs weather widget. Without it weather on lockscreen won't work too. So reflash the rom with the widget installed this time and set it up.

How to go back to stock:

Q: I like to go back to stock rom, how is this possible?

A: I can provide you here all steps which are needed to go back to a full stock rom.

0. Make a backup and than wipe all partitions in TWRP

1. Go to Sammobile and choose your country

2. Download the file and the attached Odin on sammobile

3. After downloading, put your phone into download mode

4. Make sure drivers are installed and your pc can detect your phone in odin

5. If the box in odin turns blue, add the AP file to AP tab, BL file to BL tab, CP file to CP tab and CSC_HOME to CSC tab

6. Hit start and wait until it is finished.

7. Reboot and you have a stock rom again :)

Questions about Encryption:

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

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

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 of my rom instructions it tells you to be sure you're not. So, what do you need to to in case you are still encrypted.

A: HOW TO DISABLE ENCRYPTION:

1. Boot into TWRP

2. Select Wipe

3. Select format 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: And if I want to use this rom with encryption?

A: Normally we can use the stock kernel to encrypt our device, but since the Android 7.0 Nougat update samsung makes a check kernel sides to block deodexed roms from booting. This means that even the stock kernel is build by me to disable knox and tima. So encryption won't work there and you have to encrypt your device after you set up your phone. After that go to settings, security, encrypt device. It may need some additional steps to work...

Questions about CSC/Signal:

Q: Where has the CSC selection gone?

A: To include all csc files, the rom get way to big, so it got it's own thread now, take a look here: CSC installer

Q: I have a weak cellular signal, what can I do against it?

A: Two things: first, install your providers CSC using CSC installer and flash in TWRP or flashing stock CSC with Odin. Second Thing: You can install the modem from your provider, also find your modem on Sammobile and install it with Odin in CP tab.

Q: I don't have all sHealth features, how come?

A: Not all CSCs include this feature. I recommend to use AUT or DBT as it has the best compatibility!

Q: Can I flash MM CSC on N and vis a verse?

A: No, this is clearly not recommend! You can and will face call fc's!

Questions about Xposed:

Q: Does Xposed work yet on Android N 7.0?

A: No it does not! You will end up in a bootloop when you flash it on android N

Q: I selected xposed but now I don't see an app for it?

A: Maybe there went something wrong with installing the app to /data/app from my installer script. But xposed is actually installed only the app is missing, so head over to the download page of xposed app: Material Xposed Thread

Q: I selected xposed but the app shows not active or something else with xposed is not working.

A: This can have 2 reasons:

1. You have installed latest xposed version without installing magisk, magisk is required for most recent xposed version!

2. You used 86.2 xposed (which does not need magisk) but you did not install supersu. Since 86.2 does not use magisk to be systemless it uses supersu instead!

Questions about Magisk:

Q: How can I pass safetynet?

A: 1. Make sure to fully uninstall SuperSU by chainfire

2. Flash most recent 2.4.3 SuperStock Kernel

3. Flash Magisk V12

4. install latest Magisk Manager from playstore

5. Open Magiks Manager, go to settings

6. Enable MagiskHide, systemless hosts and systemless busybox

7. Reboot the phone and check safetynet!

Q: I got out of date binary issue?

A: Since Magisk V11.1 there is no need for phh root anymore. Everything is handled inside the MagiskManager apk!

Q: Where can I configure the root settings in Magisk?

A: Since Magisk V11.1 Magisk uses MagiskSU, you can find it in latest Magisk Manager V4.1

Questions about Snapchat:

Q: Even when I did not use xposed during my setup in rom I can't login to snapchat anymore!

A: Snapchat got updated and now detects even root access on your phone!

Q: What to do to login to snapchat then?

A: Clean install the rom without root and xposed and login to your snapchat, save the app with titanium backup, flash back xposed and root. For the next update of the rom just restore snapchat backup in TB.

Q: Any other possibility?

A: You could enable MagiskHide and check Snapchat inside it so root will be hidden from Snapchat. You will be able to perfectly login without any issues.

Q: I want to discuss this problem a bit deeper. Should I do so?

A: Do that, but this has nothing to do with this rom, so please go ahead and post your experience here on this Snapchat Thread.

Questions about Kernels:

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 Magisk and supersu (or any other zip that changes some stuff in ramdisk partition) after every change of kernel!

Q: Synapse shows no UCI support!

A: Most comon issue is that no busybox is installed. Download the one from here: Latest busybox and flash it in recovery.

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.

Questions about Root:

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, simply reflash your preferred root method and it will work again!

Q: I selected phh root but my phone tells me I am not rooted!!

A: There are two possibilities:

1. You have mixed supersu/phh with magisk.

2. You did not install phhs root app from playstore.

Q: I get a warning about binary out of date. Help!

A: That happens on latest Magisk V11.1. Reason: Root has fully moved into Magisk Manager, no additional app required. Uninstall phh or supersu apps and only use magisk!

Q: I want to use su hide on my phone, how to do so?

A: Both below variants are outdated, I recommend to use Magisk with its build in MagiskHide. Check the thread: Magisk Thread
