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

A: Update your bootloader, modem and TWRP recovery. 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-G935F/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 (like a cloud) 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

Q: I installed Viper or other sound mods, but they won't work, why?

A: You most likely missed to freeze sound alive, if you did this and it's still not working you it's due to the kernel. Stock kernel doesn't support these mods since we need a permissive kernel!

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.

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 batman 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 BatMan control settings after a clean base update, why?

A: Backup for BatMan 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 BatMan 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.

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: Encryption does not work anymore on Nougat roms with TWRP installed, sorry to tell...

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: There are some test version of Xposed on N, I don't recomend to install it!

Questions about Magisk:

Q: How can I pass safetynet?

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

2. Flash most recent BatStock Kernel

3. Flash Magisk V13.3

4. Open Magiks Manager, go to settings

5. Enable MagiskHide, systemless hosts and systemless busybox

6. Reboot the phone and check safetynet!

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: What to do when I can't login to snapchat?

A: Clean install the rom without root and login to your snapchat, save the app with titanium backup, flash back 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.

Questions about Kernels:

Q: I want to switch kernel, how?

A: We have systemless 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: 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.

Questions about S8 Ports:

Q: I have the problem that on each game I start, the screen becomes black, why?

A: This happens on all roms if you haven't selected S8 navbar AND updated game tools via samsung store. I will explain: the new s8 has an updated game launcher which works together with the navbar. The rom itself includes an older version of that app to work well if you don't choose the navbar. If you update the game launcher, the store will think you got a s8 (as this is a full s8 port). After that it installs you most recent s8 game tools and you got this issue with black screen! Solution: don't update that game tools!!

Q: I have a GAP on the stock launcher with no s8 navbar, why?

A: Samsung recently started to update all their apps via playstore. So if you update the launcher via play store, the app will be stock from samsung and not modded anymore. Means that GAP will appear again after the update. Solution: simply don't update the app :)

Q: I have a virtual home button on the AOD and it won't go away!

A: You should be able to update the AOD app via samsung store, that will fix it.

Q: On AOD analog clock I can't see the clock seconds and hours on the first clock, all others are working fine. How to solve?

A: I'm aware of this and will try to fix it on upcoming updates!

Q: How can I get camera stickers to work?

A: By flashing the provided fix from the OP :)

Q: How can I get secure folder working again?

A: I dropped support for secure folder officially, but there have been some discussion about a fix, check it here
