The guy is my hero of devs [emoji847]

Answer for all:

Yes, it is safe :good:

But it's make not more really sense:

v5.x changelog:

SYSTEMLESS DevBase has been removed due to the fact, that in case of modern devices/firmwares we need to perform many changes physically in /system anyway, so it loses the sense of use here. If you liked it - you can still install it separately from here...

https://xdaforums.com/showthread.php?t=3517178

So I am waiting for the future changes of the systemless mod...

PS. For look and feel of the Rom (it's like stock, but smooth like butter...)

roger roger

i will try an report
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
I feel this was covered already, however I couldn't get it to work for me . I need to see if I understand correctly.

I want to use my local CSC. My CSC is BMC which is found as part of the XAC multi-csc.

Should the "skip CSC" option allow me to retain my CSC?

Steps could be:

1.Return my phone to factory via Heimdall or Odin. Use the home CSC.

2. Install TWRP

3. Ensure flag to keep CSC is set in options.prop and it's in the root dir.

4. Install

5. Win.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Calvin.manneson:
in options prop,use 'KCSC' (will retain existing csc)

don't perform any wipes before flashing zip.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] :
I'm interested in the response here - no matter what option I choose I have not been able to flash this on my W8 since the January update.

I get an error in TWRP stating current CSC not supported and the flash is aborted. I am on latest bootloader, etc.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
By not performing any wipe, will it still result in a debloat ROM? Or will I have all the apps that come with my CSC?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Calvin.manneson:
unfortunately yes...tho re-read the op about debloat(physical/virtual)

you have options....

will I be able to use tkkgs1994 csc selection with new update. past few updates never worked using xac csc
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] _alexndr:
Bad news :(

For some reason S2DRC3 can't be installed without wipe data over U2DRB7 (I experienced FCs & freezes without wipe data). It is not because of v5.4 - seems like S3DRC3 base is somehow older than U2DRB7, despite security patch level.

As my work is almost done - I will share it anyway, but you need to perform clean install if you want to use S2DRC3

The best solution for you is to install pure XAC stock ROM via odin (with CSC_* file, not HOME_CSC_*), then install TWRP, then dirty flash my ROM. "Keep current CSC" feature will save all your current CSC content

Wow! That was fast, nice work!

Downloading now, thanks :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Tom Mix:
so far,

ok it worked. despite the fact that the xposed-installer states this is not safe for samsung tw roms.

as i said: this ist my only tw rom i am messing around with.

@ board

are there good guides or experiences on how to make this rom google free?

and if it is not possible: how can i get the rom to the minimum google application presence? lets call it almost google free.:rolleyes:

i just started testing with g-killer aroma installer. lots of options there...

https://xdaforums.com/android/software-hacking/aroma-google-services-debloater-t3668456

has anyone tried before and can make a recommendation:confused:
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] blazethelight:
It's not safe? What do you mean?

It's clear, that is working without official support or something.

It's the Rovo89 xposed module for (Samsung TW) Nougat.

Please never update the API via Xposed self update.

I don't know if it's working after self update (possible not!).

I don't know about the old thread / source.

This is the only source I find actually:

https://xdaforums.com/xposed/xposed-android-nougat-sdk-25-arm64-t3639221

Working devices and Roms (include our device): https://xdaforums.com/xposed/unofficial-list-roms-device-nougat-t3641607

After using over since 6 months with Nougat and Alex Dev Rom, I doesn't have any issue or something.

With Lollipop I had sometimes warm device, force close and reboots.

In my opinion it's safer than SDK23...

(Note 3 time).

PS. A thanks is gentle... [emoji6]

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Tom Mix:
more precise

i guess it is just a coincedence, because i downloaded the latest

SDK24 xposed module from the official repository: http://dl-xda.xposed.info/framework/

http://dl-xda.xposed.info/framework/sdk24/arm64/xposed-v89-sdk24-arm64.zip

and i use the:

[UNOFFICIAL] Material Design Xposed Installer [25/1217] by DVDandroid

inside the installer there is a red thumb down for the installed framework on

samsung roms. i guess the description was never updated...

however: i do not have fcs so far.

and it seems that my goals cant be achieved: scramble lockscreen layout and quick-unlock on correct pin... :silly:

i am way to spoiled i guess...

p.s.: i do not get the biometrics-hype (fingerprint, mug, ...) because it is a huge drawback in security, just a win for

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] _alexndr:
You made something wrong.... Above message is displayed

only if you force not supported CSC

("Keep current CSC" feature will not be used then)

Detailed steps:

1. Install pure stock ROM for your country using PC Odin (load then CSC_*.tar.md5 as CSC package, NOT HOME_CSC_*.tar.md5) - it will perform clean install automatically which is required to set CSC properly

2. Install TWRP and perform format data to remove encryption (important: do not perform other format(s) - especially do not touch /system as we require your CSC content!)

3. Install my DevBase with default settings (important: I mean do not force any CSC, because forcing CSC works only with CSCs listed in post #1, make sure that you do not have also forced CSC in options.prop placed in external sdcard)

During install you should see following messages:

[...]

- Backing up current CSC pack...

- Wiping system & preload...

- Installing system, please wait...

- Restoring current CSC pack...

[...]

Above means that "Keep current CSC" feature has been used successfully :cool: (you can use any CSC above way even, if it is not listed in post #1)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] dorf18:
What causes forced CSC? I did nothing to ROM kept default. I have CSC selection on my SD card does this cause forced CSC? Anyways I've said forget it staying on stock rom and will just deblot myself

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
I have the g930w8 model. I followed these directions and it did not keep my current CSC as BMC.

I've read and re-read to be sure I am following closely, and its such a simple process that I believe I am following your directions properly. the only setting i changed in my options.prop was skipblcp=true.

Any further suggestions?

Edit: Is it because our CSC (BMC) is part of the XAC multi-csc? (DBT was applied instead) https://imgur.com/a/8oSvr
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] zeestats:
Hi [MENTION=7184490]Alexndr.[/MENTION]..

I have some suggestions if you kindly consider...

1. App lock

2. Some gestures on home screen (swipe up, swipe down, single tap double etc)

3. Separate ALEXNDR customization setting ( just like Sec setting in sec Rom, Bat setting in Batman Rom etc from where can adjust battery style, network monitor, clock setting etc)

4. Screen Recoder and screen shot in quick notification setting.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
This is a devbase. What that means, its a a base rom you can use to make your own custom rom. Making these changes on the devbase would defeat the whole purpose of what is being achieved here.

---------- Post added at 07:53 PM ---------- Previous post was at 07:43 PM ----------

I wonder if the whole g930w8 problem is because of the naming of our device? its heroltebmc and not herolte. Could mean nothing, but I am trying to figure out why I can't use my own CSC.

Next level: How do i create my own rom based on this rom with the XAC mult-csc? I'm not well versed in stock samsung roms.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
Here is my CSC work around for the g930w8.... I'm not much for tutorials

We want to replace the current multi-csc with the XAC-multi-csc

1.Extract cache.img from the stock rom's *.tar.md5. either CSC file is fine.

3. Once you have it extracted you'll need to make it so you can mount it. I'm on Ubuntu, so I used sim2img to create a raw file from the sparse android cache.img file.

3. Mount your raw cache.img file, and extract the folder named system from sec_csc.zip to wherever

4. Open Alexandr's zip and replace /ALEXANDR/csc/system with the folder named system that you just extracted from sec_csc.zip

5. Rename zip to force BMC (or whatever carrier code you want from the XAC multi-csc) This is important, as it won't install otherwise.

6. Install as directed by _alexandr

7. \m/

EDIT: This method is now obsolete. You can fix the csc issue by restoring your original EFS backup.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] _alexndr:
Screenshot you posted shows that your CSC (shown as "Original CSC" in PhoneInfo) is still DBT (because the installer check content of /efs/imei/mps_code.dat to check current CSC - it is the most reliable!)

Content of /efs/imei/mps_code.dat may change only with clean install (it matches then to /system/csc/sales_code.dat - in case of S7 and older phone(s)).

Could you post here a screnshot from PhoneInfo -> CSC ??
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] pixiebob:
_alexndr: big thanks to you for the update , hope you will keep your S7 very long time
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] :
To be sure I understand, your zip file starts with BMC for Bell I believe. If I renamed your zip file to start with RWC for Rogers - I am good to go ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
Help me understand.... It may be possible that even with a clean install using Heimdall, that my EFS may have information pointing to the DBT sales code?... My guess from previously installing a custom ROM that uses the DBT sales code?

Thankfully, I have a backup copy of my original EFS somewhere on my external hard drive....

But for now my method appears effective....

Edit: Aftter inspecting /EFS/IMEI/omcnw_code.dat, It has DBT inside of it.... However, /EFS/IMEI/sales_code.dat has BMC inside.. and /system/EFS/IMEI/sales_code.dat has BMC inside.

I may want to locate that EFS backup....
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
You want to restore your backup of your EFS instead. You can boot to TWRP, connect a usb cable to your phone and computer, open a shell using adb shell and run

dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS

This will restore your original EFS and fix your CSC issues.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
Problem solved! I restored my original EFS and now the devbase installs as intended!

Thanks for all the help [MENTION=5150393]_alexndr[/MENTION] !!!

[MENTION=804010]bill_in_mtl[/MENTION]
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] _alexndr:
The installer prefer value read from /efs/imei/omcnw_code.dat, but in case of S7/S7 edge "omcnw_code.dat" file should'n be there at all !!!

Do you still have /efs/imei/omcnw_code.dat file after restoring your old EFS backup? (you shouldn't, "omcnw_code.dat" files exists natively in S8/S8+ and newer devices)

You most probably installed a S8 port in the past, which left in /efs mentioned above "trash"
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
Nailed it! I had installed an s8 port at some point. After EFS restore, that file is gone.

Thanks [MENTION=5150393]_alexndr[/MENTION] for providing DevBase and the update!

I already used the previous version of DevBase and updated a few days ago. With DevBase version 5.1 the magisk.img has been automatically mounted to /magisk. I'm missing this in the new version.

I can't remember changing any configuration value so that magisk would mount itself to /magisk. After reflashing 5.1 the magisk.img is mounted again to /magisk.

[MENTION=5150393]_alexndr[/MENTION] did you change anything according to magisk.img "automount"? Do you know how I can restore the v5.1 behaviour with v5.4?

Thank you very much in advance!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] _alexndr:
In case of Magisk v16.3 symlinks like /data/magisk and /data/magisk.img have been removed (content is still available in /data/adb)

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
Ok so the issue is the omcnw_code.dat file again.

It appears its now part of the CSC (EFS) for the s7 in newer releases (at least for the g930w8). It has XAC (which is the name of the multi-CSC) inside instead of BMC and this confuses the installer. I deleted it in recovery and the Rom installs fine.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] RukusX7:
Good point! I did test a custom kernel... I didn't consider that a custom kernel would mess with the EFS.

When I did restore my EFS backup... the EFS restore was causing a bootloop at the first screen...which prompted me to flash stock once again. So it's possible the EFS backup didn't take properly and what remained was a modified EFS from testing the custom kernel.

At least I have an idea again for the future. If i restore to stock again, I'll have a closer look at the files in the EFS partition to confirm.

Thanks again!

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] _alexndr:
According to latest reports seems like I was wrong (tested only the most problematic scenario U2DRB7 -> the newest)

Following update scenarios are SAFE if you want to keep all data (dirty flash over previous version):

(a previous) -> U2DRB7 -> S2DRCC -> S2DRDC

(a previous, except U2DRB7) -> S2DRC3 -> U2DRC6

Following update scenarios are NOT SAFE (dirty flash is NOT possible, requires wipe data):

U2DRB7 -> U2DRC6 -> S2DRDC

U2DRC6 -> S2DRCC

Conclusion:

If you are using U2DRC6 at the moment - just stay with it, it does not make sense to update to S2DRCC (same changelist, same security patch level)
