Whenever i tried to install this ROM, i can't install any apps from google play store. The download progress will keep on going multiple times (dowloading 3 times for one app) but not installing anything at all. I also can't install magisk app (tried flashing from TWRP but the app still isnt showing up). And when I flash the custom kernel, my camera app just shows blank, then an error message popped up ( basically camera is unusable)

hello

samsung dex does it work?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
while installing the rom Samsung Dex is one of the feature apps you can chose to have restored, I've not heard people complaining that it doesn't work. follow absolute best practice for the install and you shouldn't have any problems. if you have the latest OneUI update then use the latest build of ProjectX. boot into twrp after backing up, format data and type yes to confirm. then reboot from recovery to recovery (important step) and then you can wipe cache and dalvik and then copy the rom zip from PC to your phone.

can I flash july rom with august sequrity patch
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] hayalci:
Thanks
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] LambdaChi:
I did try this myself. It does work and it does boot successfully after flashing.

I didn't try many things, but a popup that "android.process.acore" has crashed repeatedly pops up frequently. This appears to be related to the contacts app, which crashes upon opening.

So yeah, it does boot, but doesn't work too well. (Which is obviously expected)

I'll retry with July patch.

Already big thanks for putting in the effort for this rom!

[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
FOR PEOPLE WHO CAN'T INSTALL APPS

if you check when installing ProjectX you'll see if all partitions took a decent amount of time to flash. if the vendor partition flashes in 1 second then it didn't work and you'll have a knock on effect in the data partition most commonly.

The Solution... the install procedure should be boot twrp, format data. then go to twrp's reboot menu and reboot to recovery before wiping dalvik, cache and flashing ProjectX.

when you format data you should always reboot twrp to make sure twrp is working with the cleaned up file system.

camera issues with custom kernels are a thing but check out the latest Prime Kernel posted today. a lot of testing was done on that.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] AmeyA:
Is the ROM rooted by default?

I am not able to use a couple of banking applications due to this. Is there any way I can remove the root?

This ROM looks very good and this is the only thing that constraints me using this ROM.

Thanks.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Gully.Moy:
Thanks guys, seems great so far!

What amazes me is how persistent the branding is. My phone was originally provided on the Three network, but I thought just flashing the generic firmware would erase all traces of Three. However, no and even on Project X I get Three on my case with a splash screen on boot and notification about about apps. Is there anyway to completely debrand the phone or at least block these notifications now I have root?

Cheers
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] madadictromtester:
if its a snapdragon model then it wont change the splash screen. Only on exynos it is possible
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Gully.Moy:
I am exynos, still got splash screen and notifications from original carrier.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
before or after you flashed the zip open it with a decent file manager and copy the boot.img file. if you then boot into twrp, select install image and flash the boot.img to the boot partition in twrp you'll be un-rooted. just uninstall the magisk app too.

please look up magisk hide options though, about 90 percent of apps that try to detect root can be fooled. it really does depend how far that bank asked it's app developers to go in detecting root.

I updated to the latest version for the Snapdragon 5G version. My only complaint is the"Restart/Reboot" option is missing. It is just Power Off, and that is it.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
in the latest version v4.5 / v4.1lite it should be turned on by default but if it's not go to settings / advanced features / global action settings and select what options you want to show.

The v4 link is for the 4.1 version it seems.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] bladez:
I have 2 bugs in this ROM (4.1 Exy).

1. Bixby Routines sometimes starts, sometimes don't start. Turning routines of/on fixes it temporarily.

2. Fingerprint sensor sometimes doesn't react. Seems like it tries to light up the sensor, but does so for too short of a time and not bright enough. Turning the screen on/off temporarily fixes it.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] N0he:
Have you flashed it? Can you check the version?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
I havent as yet, so cant answer that yet.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
v4 is the most current PUBLIC build available, there is a v4.1 based on the October update that's a private build. private builds are offered to any donars first and held back a while. in this case we're skipping October as a public build. Nov might be late from Samsung as it's gonna jump to OneUI 5.0 very soon.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] N0he:
I tried it myself now, it's the 4.0 version based on the September security patch. Which brings me back to the question whether it is fine to flash it over the newest stock rom which is based on the October security patch?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
Ah ok, well if you look at a reply I got I thought 4.1 was included - https://xdaforums.com/t/projectx-rom-oneui-based.4450045/page-6#post-87695679

So maybe it isnt.

I,

I don't arrive to flash ProectX Rom.

After to install Zip project and Magisk.zip. Reset Dalvik cache. But when system restart, it's blocked. Il have use last version of TWRP 3.7.0 ?

I have use last stock rom

Thanks
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
you DON'T need to root the rom, just install the magisk apk that buried inside the ProjectX zip.

the last 2 versions of twrp should work fine.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Marcopololo:
Ok, but when I have install TWRP, vbmeta,multidisabler, format data.I testing again.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
don't make up your own instructions for flashing twrp, follow what the install instructions on the twrp page.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kluskarafael:
Is the rom compatible with some custom kernel?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
it should be compatible with Prime, Klimbo and Bandido kernels

I'm on the stock rom with the October patch, can I go to the latest projectx version?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
yes that will be fine. for a good install you need to format the data partition which wipes your internal storage. when you do it you must use twrp's reboot option to reboot from twrp back into recovery again. don't skip this step and remember to wipe dalvik/art and cache afterwards then everything will work.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kodein:
Hi, when will the new build come out? I'm on the paid version....
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
only Exynos has gotten OneUI 5 so far, that's being worked on. some snap phones got a regular November update but that will almost certainly be skipped. probably looking at mid December before OneUI 5 hits for the rest of us and we don't know if there will problems there too.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kluskarafael:
I have a problem, all other power off menu functions are gone, remaining only power off function

what should I do ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
do you mean you had them and lost them ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kluskarafael:
The rom already started with just the power off and restart

I flash a profile on konabess, and the phone didn't even boot, so I flash the projectx zip boot.img through odin and the restart disappeared

to try to solve, could I flash the rom again over the top of it?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Revontheus:
Just do a clean install, and use the ROM stock. If you install third-party modifications, do not expect the ROM to properly work.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kluskarafael:
I did the installation from stock, without using third-party modifications, the only mistake I made was not restarting the recovery.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
restarting the recovery is needed, twrp cannot properly access data sometimes after a format. you also can flash the boot.img from the zip with twrp (patched or unpatched). try a dirty flash if you want, that will also restore the kernel.

not sure what the cause of your problem is though. does konabees patch the kernel ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kluskarafael:
I did the process correctly, but even so the buttons disappeared.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] kluskarafael:
I flashed the stock to install projectx again, I followed exactly the steps you described, and now the rom starts without the restart button, and worse, the magisk just disappeared, it's like the rom didn't come pre-rooted, even doing flashing magisk.zip through twrp just doesn't work.

About Konabess, it is an application to apply undevolt and overclock profiles in the kernel.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
the rom does come pre-rooted we can't make it install the magisk app, that's all you need to do, install the magisk app. there's even a copy of the apk inside the clean folder in the zip.

if you have an older version of ProjectX you'll have to activate the power menu options in the global actions menu found in labs.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] N0he:
If I install this rom now, will I have to set up everything again once the version based on One UI 5 comes out? Or will it be just simply flashing?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] wh1tekn1ght:
Not sure if this is rom specific or general issue on S20 FE but I cannot use USB OTG device.

I have an external SSD which is correctly recognized on my Galaxy A41 (stock rom).

But when I connect it to my S20 running projectX rom, it is not recognized.

Nothing appears in "My files" app. MiXplorer generates an error ([Errno 32] Broken pipe).

Anyone else facing this issue?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] petrapas:
Did it work with the stock ROM on the S20 FE?

In the past one could flash a custom Kernel which added the USB OTG, if a custom ROM lacked this feature.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] petrapas:
The ROM looks really promising.

Does it include Samsung DeX?

Hopefully Samsung will publish OneUI 5 for the Snapdragon S20 FE soon.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] wh1tekn1ght:
Been running custom rom for a while so I cannot say. Also checked custom kernels and haven't found anything about OTG
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] petrapas:

In the past there were apps activating USB otg like:

No USB otg would be indeed a dealbreaker.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] guilherme2707:

2. Do I have to do a clean install when installing a newer version? Do I need to format the data?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Revontheus:
Clean install by using ODIN to flash the latest version of OneUI. After which, install the ROM.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] vgpclife:
Hello all. I was hoping to get some clarification on something. I'm reading over these pages and I'm not totally clear on something. I have the S20 FE 5G. Its already rooted with TWRP. I still have OneUI 3.0, Android v11, Baseband G781USQS1CUAB.

What steps do I need to do first to be able to install this ROM? I see some mention of installing something else first via Odin but do I need to worry about losing TWRP? Or root access?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
each release of ProjectXRom is based on the corresponding monthly update from Samsung. it's best if you've updated to that same monthly update or at a minimum not being too far from it.

in short you'd need to update to the last version of OneUI 4.0/1 to be able to use the last version of ProjectX.

if you updated to OneUI 5.0 you'd have to wait until those versions were finished.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] vgpclife:
So on past phones, I'd normally just pop into TWRP, wipe the phone and install the new ROM. Why would I need to worry about updating to the latest anything if I'm just going to wipe everything and install a new ROM from TWRP?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
it's not a custom rom on a device that's EoL, things can and do change under the hood. not being on updated firmware would be like flashing with Odin but choosing each slot randomly out files from the last year.

[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Revontheus:
I am on Android 13 (GWA3) and flashed the latest beta of this ROM on my G7810.

I dont have any issues with my fingerprint reader. Perhaps you need to take off your tempered glass.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] apaxtc:
Yes man . it works on the beta .... but not on the latest stable one

by the way, what do you think of the "beta".....does it have problems or is it quite stable?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
the code used in ProjectX for the fingerprint reader is unaltered from stock OneUI. we don't change anything related the scanner at all.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Revontheus:
If you are using the Android 12 version of this ROM, then you should be on Android 12 firmware before flashing. If you will use the beta (A13), then you should use the latest A13 stock firmware.

If you use Android 13 stock firmware and flash the Android 12 version of this ROM, then you might encounter problems.

As for the beta. It's perfectly stable for daily use. It just lacks the advanced reboot menu of the A12 ROM, but other than that I have no issues.

[G1 Android Development] marvinp:
My phone keeps restarting by itself and I'm guessing something is failing. Does anyone know where I can find system log files like syslog that could have logs about system failures, etc...? I've tried logcat but it only seems to display logs since the last reboot.

Does anyone else get these random reboots? So far I haven't modded anything on my phone, I've only telneted into it and browsed the file system. It's been rebooting on its own ever since I got it. It's running RC28.
[G1 Android Development] mrboyd:
You could try running

logcat > /sdcard/log.txt &

Which should in theory dump all the log in a file on your sdcard in the background which you could analyze post-mortem.

Of course I haven't tried, and it might just brick your phone or at least be the cause of the crash. So do at your own risk.

In truth you should call T-Mobile support and ask them.
