First of all great work man amazing rom,ultra stable and clean.

2 days ago i flashed ALEXISROM_1.3.1_S9.zip and its working so good but i seem to have 1 problem and thats it.

I took some pictures yesterday and all went well and few hours later i pull my phone to enter gallery and no photo there.

First i thought no big deal maybe gallery not updating but then no SD Card acces it says Corrupted i removed card and put it back in without restart it works a treat,setup my pin,iris,FP etc. pull out my phone it asks for PIN after reboot,phone reboots in my pocket and SD card says Corupted.

Today my phone rebooted 2 times and every time SDCard said Corrupted.

I clean card,format,check even choose in phone options setup card (format to use it) and its still rebooting randomly and corrupting card even tho reinserting the card fixes it.

Without card its fine.

S9 Exynos SM-G960F

Should i clean System,Cache,Dalvik Cache,Data and clean install 1.4 version?

Thanks in advance and sorry for the long post

I am getting the Camera failed. Tried shutting down all apps, but still didn't work. Am on 1.4
[Samsung Galaxy S9 & S9+ Cross Device Development] j1gga84:
Will the "from time to time" camera error been fixed some day or is this just impossible and we have to live with it? I think the camera failed error that occurs from time to time is very annoying for people that take pictures with their S9(+) Camera a lot ;)

Is it known what causes this issues?

After two days after flashing the lastest Rom 1.4, I want to do a backup trough TWRP what I did.

After rebooting the phone from TWRP, I lost my baseband /efs folder!..., I cann't call or use 4g.

In the software overview he said "Basaband Unknown" even I install the latest modem & bootloader DTD7,

But without succes...

How to solve this, flash the original firmware with Odin? Or is there another way to solve this problem?

Thanks Anyway!

Usually, this should fix the issue... Maybe try to flash one of those files, depends what you are using. Let the others correct me if I'm wrong, but I think they should be flashed when you have an issue like this. All credits to [MENTION=1262300]alexndr[/MENTION]

[Samsung Galaxy S9 & S9+ Cross Device Development] sc7es:
I downgraded to 1.2 versión with oneui 2.0 until alexis fix the camera error (I hope he can fix it). I love this rom and I love all the things of oneui 2.1 but I use my camera so much and that error is annoying :(
[Samsung Galaxy S9 & S9+ Cross Device Development] Cheech1976:
I tried downloading the rom thrice now, every time the zip file is corrupt, so there´s something wrong with the upload?
[Samsung Galaxy S9 & S9+ Cross Device Development] Serpentinefire76:
There are mirrors provided by Leon here
[Samsung Galaxy S9 & S9+ Cross Device Development] Cheech1976:

[Samsung Galaxy S9 & S9+ Cross Device Development] Leon:

Did you try the link provided by Hellrock86 on the same page?
[Samsung Galaxy S9 & S9+ Cross Device Development] Cheech1976:
I got the same error with the file from Android host, twrp states the file is corrupt.

I will Try again later, hopefully I will be able to obtain a good file, don't know, if it is somehow related to my internet or my pc, but I should think not.
[Samsung Galaxy S9 & S9+ Cross Device Development] amuro1:
is this error for S9 + models only? So far I haven't had it with my normal S9

[MENTION=6114446]AlexisXDA[/MENTION] Ieri ho flashato l'update senza installare il DTD7 Package, adesso, con un sonno pazzesco l'ho flashato scordandomi di fare il backup dell'EFS...mi sono letteralmente fatto la cacca addosso...fortunatamente è andato tutto bene... hahahaha
[Samsung Galaxy S9 & S9+ Cross Device Development] AlexisXDA:
Never seen an error like that

The only bug is single take that causes camera error, but just when you go in single take mode
[Samsung Galaxy S9 & S9+ Cross Device Development] j1gga84:
So is this something that can be fixed one day?

Does another camera app helps in this case to avoid the error?

I think 90% of the users take single photos instead of multi pictures.

I have successfully upgraded my G960F from 1.3.1 to 1.4 and also flashed the DTD7 Firmware via TWRP (I am on DBT And have Vodafone Provider). Great ROM!

I only (still) have these bugs:

- power button doesn't work to open boot menu, only locking screen (was also in 1.3.1)

- in the quick panel I am missing the buttons for Screenshots and VoLTE activation (I had them in 1.3.1, now they are missing) does this have sth to do with selecting options in aroma installer?
[Samsung Galaxy S9 & S9+ Cross Device Development] Nisar Ahmed Nisar:
A big big thanks to Alexis. This is an excellent rom one annoying bug for me is random restart which may be related to sd card since after restart sd card is shown corrupted and after manual restart it is ok again, but i can't complain. Thanks for the rom.
[Samsung Galaxy S9 & S9+ Cross Device Development] xxBeatsByDrDrexx:
Same issue here but i reverted to 1.31 after trying out 1.4 and no random reboot so far.

Only thing i did differently is to save pics and everything on internal storage,whenever app asked me to store on SD i said no and hopefully no issues with that since i can just move pics and video via file manager.
[Samsung Galaxy S9 & S9+ Cross Device Development] Nisar Ahmed Nisar:
Thanks Mate, Will try the 1.31 and inform how it is going, but first let's try to revert every setting from sd card to internal storage on 1.4 and see how it's going. Once again thanks for the tip.

Are you using Firefds?
[Samsung Galaxy S9 & S9+ Cross Device Development] damjang:
I have installed 1.4 rom and work ok. But I have find something strange (don't know if similar in previous versions of rom): if I check with TitanBKP through the installed system apps, some apps are listed multiple times... Circular 1.0 (listed 5 times), Filled 1.0 (5x), Gestural Navigation Bar 1.0 (10x), Backgrounds 1.0.53 and Backgrounds 5.0.00, Phone 10 and Phone 11.1.70.20 and Phone 11.0.00.51, Rounded 1.0 (4x), Samsung Keyboard 5.0.10.64 and Samsung Keyboard (deprecated) 4.9.00.7, SIM toolkit 10 (2x), Wallpapers 1.0.53 and Walpapers 5.0.00. Is this correct or maybe a problem of the rom or of TiBkp?
[Samsung Galaxy S9 & S9+ Cross Device Development] Nisar Ahmed Nisar:
No, no XPOSED, no firefds. Screenshots attached no reboot for 13 hours
[Samsung Galaxy S9 & S9+ Cross Device Development] Serpentinefire76:
Ok. For me, SD card is not mounted if I used Firefds to shutdown my device and then boot.

If I use Quick settings app, everything is normal-Sd Card is mounted as should be
[Samsung Galaxy S9 & S9+ Cross Device Development] AlexisXDA:
I mean that you can move camera modes however you want, like an app launcher, so you can hide single take, so you won't see any camera error anymore
[Samsung Galaxy S9 & S9+ Cross Device Development] AlexisXDA:
Guys I think that random reboots are not ROM related.

Is it also somehow possible to remap the bixby button with the key settings without having to install a third party app? I remember in SuperMan ROM it was always possible from the jump.

---------- Post added at 02:35 PM ---------- Previous post was at 02:31 PM ----------

Ok I see good point. I guess it depends on how fast you are with setting up your phone. For me it's quick with clean flashing. And I rather spend a couple minutes setting up my phone, than having the feeling of a dirty phone in my hands ???

EDIT, the same failures doing all the steps well, at the end of the TWR installation (error when creating fstab), when reaching the wifi configuration when it passes and looks for updates, it returns to the wifi screen, it does not allow to continue, even if it inactive and continuous with mobile data. does not allow, error exit Android settings, force closing

I have a bootloop too. What rom did you flash before this ? Also I cannot go back to pie. That gives me bootloop too.
[Samsung Galaxy S9 & S9+ Cross Device Development] Docmjldds:
On my 960F S9, can confirm the fstab issue. I did allow the install to complete. Samsung screen took a good twenty minutes before getting to setup stuff. Then after creating wifi log in and choosing cancel to use old phone for copy, would get Android setup force closing. Rebooted phone, got to Google downloading apps. Tested camera and stock gallery app. Still get gallery FC's. Currently running a TWRP restore of your original stuff.
[Samsung Galaxy S9 & S9+ Cross Device Development] ingeniousambivert:
My installation did complete and I did wait. But I got stuck in a bootloop. P.S. I was on pie before. I tried to directly update from pie to this rom. I guess thats the issue. How did you fix it ?
[Samsung Galaxy S9 & S9+ Cross Device Development] AlexisXDA:

[Samsung Galaxy S9 & S9+ Cross Device Development] Zootopia:
Coming from a Pie custom rom.

Decided to give this a go based on a very good feedback from various users.

SM-G-965F

Using official TWRP 3.1.1.1.

Tried several different scenarios, all ending in bootloop (samsung logo, blue light flashing on the top right corner...)

- First I did was to make sure I flashed the DTD7 reccomended BL and modem through Odin (v3.14)

- Always performed a clean flash first (format data => yes);

- After a couple of bootloops I decided to try the above, and sideload using TWRP the modem&firmware zip file you guys so gently shared, since I don't have it on my phone.

- ADB sideload was doing fine until it stopped pointing out an error (which I supoosed normal, according to the above);

- Then I forced reboot, flashed Rom... Still bootloop.

Also tried to flash that mentioned .zip file after flashing the rom, same result... bootloop. ::confused:

Also tried using soldier's firmaware file instead, no success.

Would appreciatte any ideas solving this, sorry to bother you, thank you.
