I recently installed Aroma ICS 4.0.4 Cyanogenmod 9 UNNOFICIAL V3.0 rom, and when i first boot my device, i dont have the Google Play Store App. How can i fix that?
First thing is, any bugs, things you dont like or anything like that post it in ROM thread, second you need gapps package for ICS ask jordfaz to give you a stripped one
I tried to post in the rom thread but, it told i need 10 posts to do it. How can i talk with jordfaz? Thanks for the quick reply
Send him a private message ask him to give/make you a stripped down version of gapps
---------- Post added at 01:33 PM ---------- Previous post was at 01:31 PM ----------
BTW, CM9 should have gapps included, did you do a full wipe before installing ?
When i wipe the user data, it gives me this error, i dont know if it has something to do with the previous error.
The error says:
Formatting DATA...
Formatting CACHE...
Formatting SDEXT...
No app2sd partition found. Skipping format of /sd-ext.
Formatting SDCARD:/android_secure...
Data wipe complete.
That's nothing important
I have another problem i just installed the Facebook application from Android Market, but after using it for a while an error appears saying "Sorry, Facebook has stopped.", and that happens with other applications as well, what can i do to fix this? :/

Many users reported booting. You have to unmount system.
Do not flash gapps. It's not compatible with miui 8.
1) Open mi app store.
2) search for "Google"
3) open and install "blue panda(du) foot print logo app" ("I can't read Chinese")
4) Click on install
5) Open the app
6) Click on blue button
7) Install all prompted apps manually ( select install unknown source in security settings)
8) after everything installed you see yellow button just open it and login your Google account
9) Enjoy.
10) Like this post if it helped you to install gapps and reduce force closes.
See screenshot for visual steps.

Same problem here, i m getting a lot of FC's from google play framework. Even my FC's have FC's
FLOSSbOxIN - Since 2016, I am a non-foogle person, nor do I have shucksfook, or anything of those stuffs. I was on Telegram and used to run the flossboxin channel, but left the application due to too much of spam and useless stuffs, and moreover, privacy issues tbvh. Now my XMPP channel is named FLOSSbOxIN too. I recently lost my M30, however, I have been for quiet sometime trying to get this M30 debloated to a level where knox also does not trip, nor where one will have to face the unnecessary Samsung bloatware and annoying analytics. Finally, I have made it to that level, after several permutation combinations.
Code:
[B]FLOSSbOxIN M305F Debloated FOSS/FLOSS Stock ROM[/B]
Released: [B]20200925[/B]
Patch Level: September 01, 2020
Build Date: [B]20200926[/B]
Base Version: Android 10
Build #: QP1A.190711.020.M305FDDS6CTI1
Kernel: [I]4.4.177-19407255[/I]
UI Core: [U]One UI 2.0[/U]
Links:
M30 Database -- AFH
DM-Verity -- AFH
FLOSSbOxIN - ROM -- Cloud - Direct Link
Odin V3.14.4 -- AFH
TWRP 3.4.0-0 -- AFH
Magisk Canary -- AFH
Installation Guide (Only For Bootloader UL On Q/10)
Download ROM from the links given.
Boot to recovery (stock/TWRP) (Guide Link)
Code:
adb reboot download
You will have to format data, as the ROM is decrypted, and coming from an encrypted ROM will give issues. For decrypting, do a "format data" in TWRP Recovery and then reboot to recovery and Wipe Dalvik/ART, Cache, System, Data, Hidden, Internal
Copy over ROM OS & DM-Verity file (do not rename DM-Verity file, keep as is)
Flash ROM - Would take around 10 minutes time for it to flash
Go to wipe, and wipe /hidden
Flash DM-Verity file
Reboot - should take around 5-6 minutes
Notes:
I have removed the setup wizard altogether
Post system starts, wait 5-10 minutes, as system tries to integrate system apps, which are newly introduced
Only necessary foogle stuff is kept, including Maps+Location, GSF & Play Services and all other foogle stuffs is removed
Somehow, even after removing the notorious HIYA (so called caller id and spam protection service), it somehow comes back with a valid internet/mobile data connection. If you wish to remove it again, boot to TWRP, mount /system and then delete the hiya service folder and clear dalvik/cache, and reboot
If any app has permission issue, then reinstall as "user" app (install again manually), and reboot sysui. Should work post that, as sometime, few apps are by default not allowed system changes by Samsung framework, and to add each app to framework is a bigggg task, and very irritating too
Still if any app (e.g., AnysoftKeyboard (see git issue), then uninstall as system, and reinstall as user
Ensure minimal apps are made /system, as they can be harmful
Features:
Fully debloated
Fully stock
Smoother, faster and has long battery run
Foogle & Samsung stupidity free
FLOSS apps included:
Aurora Droid, Aurora Store
F-Droid Classic - Classic variant by bubu
F-Droid Privilege (if you ever install F-Droid main app)
Bromite Webview is default
UngoogledChromium is the default browser
FreeOTP+ is your FLOSS 2FA companion
K9 Mail is the default FOSS email
KeePassDX for auto-login and enhanced privacy
Notification Log allows you to view several logs, once usage access is granted, and is fully FLOSS
QKSMS replaces Samsung Messaging app
Power App allows you to reboot to various modes - sysui, recovery, bootloader....
Vinyl is your music buddy
Dual-Mod for audio included
Screen capture (image & video) feature added
Data transmit (Up/Down) in status bar added (thanks Akhil)
Various camera tweaks (FOSS - OpenCamera is not included)
My hosts file is included, which enhances privacy by blocking various trackers and ads - URL
Hosts editor also included
GPS fast locking in closed areas - debug included for it
USB debug revoke option added to Dev mode
initd support added
Shutdown thread log enabled

Okay mate.
Few ways to do it.
1. By installing rooted AP with TWRP already included:->
Install September stock Firmware from my post here: https://forum.xda-developers.com/galaxy-m30/development/rom-t4167497
Use that to flash the September FW. Use ODIN via windows, and use the file: AP ROOTED WITH TWRP RECOVERY. Flash only AP. CP is optional. Follow the steps there. Ensure to flash DMVERITY.
This is one way...
Another way:
2. Flash stock ROM. Connect to wifi/mobile data and setup. Change the time to say 7 days prior to today. Wait 30 minutes and boot to download mode via the following method:: switch off. Press Vol+/- together and connect to laptop/pc via usb. Ensure usb debugging is ON and then perform. Now you are in download mode. Flash TWRP.tar file from AP. All checkboxes should be unticked. Once flashed successfully, press vol- and power button for 7-8 seconds and let go off vol- upon haptic feedback and press vol+ to enter to twrp recovery. You can let go of the buttons once twrp shows up.
Now format data and reboot to twrp again. Mount data and /system and if OS is installed boot to system, else flash a ROM of your choice.
3rd way:
3. Download FLOSSbOxIN (FLOSS/Google variant available). Extract to any desktop folder. Now open 7Zip and make a zip file with all the .img files. Choose .tar (available from 7Zip dropdown as well) and rename the tar file to say rom.tar.
Once done flash this one via AP. Ensure all checkboxes are unchecked. Reboot to TWRP following the steps in method 2 above. Format data, boot to twrp, flash dm-verity and boot to system. You can wipe cache/dalvik and /hidden if you want. Will take around 10 minutes to boot. Dont forget to boot to twrp first and flash dmverity, else you will end in bootloop.
Note: With Samsung, in case you forget to flash DMVerity, and by mistake clicked boot to system, do not worry. Switch off, or reboot to twrp and mount /system and flash. Wipe dalvik and cache, reboot. Done.

@vdbhb59 THANK YOU SO MUCH ,SIR.I was about to sell the phone coz TWRP could not be booted.
Finally,TWRP is booted huge thanks to you.Procedure 2 did not work(bootloop) and Procedure 3 gave me .binary error in odin(maybe i messed up in some steps).But Procedure 1 was easiest and foolproof & it booted TWRP in first try without any bootloops.
Now coming to Floss ROM(Vanilla).It was simple,clean and elegant and performance is good as well.I have not checked the battery life with this ROM but i hope it gives me more than standard battery life.Will be checking other ROMS as well-Lineage,Bliss,Turbo etc. and will be settling once i find ROM suitable for me.
Again thank you DEV for guiding me,giving me your time and most importantly contributing to this community !!

Anytime mate. Actually all the 3 ways I mentioned, do work. Probably, some trouble while flashing. However, no worries, I am glad you were able to boot to TWRP and flash a bloat free OS. Enjoy mate, and happy riding.
Battery life is around 1.5-2 days basis your usage. At times more, touching 3.5 days too. Again, the logic basis is always usage and background stuff.
Bliss does not boot for all, LOS does though.
BTW, which FLOSSbOxIN variant did you try? Google one will eat more battery obviously, against FLOSS one.
FLOSS(Vanilla)-[without google] review
Everything is good with the ROM but some problems i faced could be solved by following procedures:
1.If some apps does not work/launch as expected then "UNINSTALL AS SYSTEM" then REINSTALL it or INSTALL APP OF YOUR CHOICE.For eg:Vinyl player.
2.If AURORA STORE does not download apps then first give permission to Aurora Services and then rerun Store.Otherwise install GooglePlayStore manually once, update GMS and it will work.PS:You can delete PlayStore or disable if you want to.
Other than these everything is FINE.Would certainly recommend to try this ROM ?

Thanks for this mate. Though not bugs, but the app behaviour itself. The ROM itself does not have any bugs.
October release coming soon.
Dear Dev,
Thanks for the rom.
My 3 queries
1. Getting access denied on some files like magisk, odin, and m30 database.
2. Is there any aggresive battery saver or something alike in rom which switches off all functions except calling?
3. The download link to download google version is very slow and is showing close to 17 hours to download on 150 MBps connection.
Thanks and Regards

Hi Ashish,
Actually, AFH is having some issues. I too am unable to view files at times. Magisk and ODIN are Public files anyways. You can navigate with androidfilehost then my user, which is vdbhb59.
Battery saver is there, Ultradata by Samsung itself. You can use any 3rd party app too.
Google version link is quick here. Showing 25 minutes at 80Mbps.
Update - 20201017
Hi All,
Update released for the new version.
N.B., the update by Samsung never was for October 2020 patches, and was only a con, as they moved the apps & priv-app between the 2 folders, and added a very big BUG along with several privacy issues.
When I reached out to them with the details, I was blocked, and my account was suspended.
I have stripped away every bit and piece of bloat and BUGS (afaic). Security patch is still September.
Also, the stock camera is now replaced with 2 open variants, and much better ones. With the latest update, while trying to remove Knox, and some resources, the stock Camera breaks up fully, and the hidl does not link, rendering the app useless.
Magisk Canary 20201017
20201017 - FLOSSbOxIN_Foogle_V2_20201017
20201017 - FLOSSbOxIN_V2.2_20201017
Difference between the 2 versions
Difference between the 2 versions -->
FLOSSbOxIN_Foogle_V2_20201017 - this version is a bit smaller compared to the version 2.2 below. Version 2.2 contains a few more privacy oriented apps, and XDA app as well inbuilt, along with OSMAnd+ and UNLP. I have retained GMS Core and Maps as OSMAnd does not cover many parts of Asia and Russia.
FLOSSbOxIN_V2.2_20201017 - this version contains the following:
SMS - QKSMS
Mail - K9 & pEp - both open source. Both more reliable then stock.
Clipboard - Added function for clipboard. Probably, some apps may not work with it. Ideally, it will come as an option with pop-ups.
Maps - GMaps, OSMAnd+, UNLP
Music - Odyssey & Vinyl
Video - MPV is a great tool. VLC somehow does not integrate with Samsung while building, so have not added it yet.
SimpleTools - Gallery & Calendar alongside stock ones. Do use the open source ones, as they are fully privacy oriented. Some folks like Samsung one, but it is filth filled, and I have taken huge time out to prepare these stuffs, so do try.
Camera - OpenCamera & FreeDCam have been added. I have been using these 2 since a long time, so, do use them too.
Browser - 2 variants of Ungoogled Chromium, Bromite Webview alongside Android Webview.
Terminal - Termus. Do install the relevant addons from F-Droid/AuroraDroid and enjoy.
Downloader - Download Navi is prebuilt.
Launcher - OpenLauncher is added too, which is a better option compared to Samsung one. Use the one you prefer.
Stores - As usual F-Droid (2 variants), Aurora Store and Aurora Droid.
The ROM has been tested completely, in terms of retaining of Samsung features, and additional stuffs that I could integrate. I hope on getting Stock custom ROM soon, if the framework parts pans out, and may have inbuilt power menu options, more QS stuffs and theming, all again depending on time I can spare and framework nuisance.
It would be great if Theme option is added

Did they replaced system.img with super.img ? Samsumg keeps adding their security related sh**t in the name of security patches making difficult for devs to mod their Roms.

Nope. They moved few /system/apps to /priv-app and to /vendor and made a lot of framework changes to ensure boot goes for a toss. One of the worst was how system auto cleans at a schedule. Also busybox installation fails due to /system free space being minimal.
Few more things, which I think cannot explain here.
