Hello everyone this is my first post here I'm looming to get an answer for a rather annoying problem here. About since a week ago i have been getting this error which says "*app name* can't be installed (Error code : -504)". Now the weird this about this error is that it only comes up on apps which are over 50 mb or which are classified as big apps. Also I'm aware of error 504 which is a gateway error but this is completely another thing because this occurs after the app is done downloading it only shows up while the app is installing. And the weird thing is that the same thing occurs when I try to download the app in apk form too. So any app under 50 mb will install but over that its going to give the same APP NOT INSTALLED error. So far iv troed using an antivirus that detects nothing and clearing cache through clean master and even through a factory reset as well as clearing data and cache of the market and nothing is working please help. My device is the Infinix hot note and I'm running 5.1 LP
I have oplus Xonphone 5 (Android 4.4.2). My phone is having virus/malware which have accessed root permission and made itself a system apps and now they are automatically turning wifi on/off and downloading tons of other apps (e.g. Hot cam, UC news, Ram booster etc.). Whenever i open running apps there are System.bin and systemMultimedi are running and consuming battery. sometimes they close all other apps and download malware. I have tries following thing which didn't solve my problem:
1. Soft and Hard resetting of phone.
2. Rooted my phone and using root browser tried to delete/Uninstall these files(viruses).
3. Tried uninstall all newly installed system apps by using Kingroot but they again showed up.
3. Cleared the cache partition and then hard reseted phone.
4. tried to flash the ROM but failed.
Please help me recover my phone . Thank you in advance.

This is really a big problem and if not solved soon you will be in great trouble
I suggest you to first uninstall root and then flash the stock rom again
This is the last option I have
I dont think you can do anything beyond that

I will also suggest few senior members whom I know to solve your problem as soon as possible
This could even be a police case if the malware tries to do something beyond this
If you think something more suspicious than just downloading appps and toggling settings
Then I would highly recommend you to switch off your device and keep it aside until you find a solution at xda

Rootkit on an android? Now that's rare. If you tried every conventional method, I doubt anything is going to work. You can try disconnecting from the internet, check your running processes and services, kill them if found, scan with Malwarebytes and attempt to locate problematic files manually using explorer. There have to be some specific apps that are being installed, can you name them?
And full factory reset did not help you?

These are the steps I done
1. Add a shortcut of the apk to the home screen from the my files app
2.Power off the phone.
3. Cleared the cache partition.
4. Restarted the phone.
5. Quickly installed the Apk by accessing the shortcut from home screen.
(Now it's installed )
6. But the launcher keeps force stopping.
So I cleared touchwiz home's data and cache from app manager.
7. Now it's working fine.
I also installed Bixby app through the same process.
Hope this solution works for all those who face the conflicting signature problem.

For some reason i was reset(hard) my phone (by wiping data + cash partition). After successfully reset when device is turned on i found an unexpected error like below:
Device Locked
Device Management has restricted certain features on your device.
Please contact the administrator to re-install Device Management to recover your restriction.
Now I can't access CAMERA(security policy restricted camera), SD-Card not found(showing not inserted), Bluetooth is also disabled. USB-debug is also disabled although DEVELOPER OPTIONS is enabled. Screen-shoot is also disabled. I have flashed my mobile multiple times after that occurrence with proper updated files(AP,BL,CP,CSC,pit). But my problem is still remain. I really don't know what to do. Plz help me out. Thanks in advanced.
N.B: I have also used a fresh gmail account but problem still remain. I have a backup EFS folder but i can't root my phone as usb-debug is disabled. I was tried multiple times to root my phone by CF-Auto root for sm-g930k but it stuck on KT logo and as a result i have flashed it again and again. :crying:
Sorry for my bad english.

In set-up wizard I login with google account and choose restore from cloud
When it's completing setup (my apps and data) it hangs on 47 ou of 87
Waited for a whole day for it to finish...nothing
Reset device 2nd time
Did another google backup on my old phone
Same thing this time at 60 out of 87
Edit:
Factory reset
No google account this time
Managed to update apps already installed on device, can't install new apps without signing-in
Disable all automatic updates etc.... sign in with google account, can't install apps "waiting for download"
also had this error during restore but doesn't seem to matter
Updating apps on playstore doesn't work, installing new apps also doesn't work...everything gets queued up and no progress
Really disapointed with this, maybe it's faulty?
Edit:
Did yet another system/factory reset. And this time I chose restore backup from another phone, hope it works.... update: it didn't, same thing 36 out of 87
UPDATE: MAIN POST EDITED
So I added my google account after setting up the device, I managed to restore a lot of apps BUT some of them failed and/or can't install them from playstore.
Tried deleting cache and storage from PlayStore. Also tried disabling MIUI optimizations and even letting the screen on ∞ time and let it install overnight......nothing
The list of apps appear to be random, so I'll just keep updating it
The list
Android system webview - can't update
PokemonGo - can't install
Flud - can't install
For apps download/update change the connected WiFi settings to "static"
For crashes I would suggest to "clear cache" and "clear data" of these apps: Phone, SIM Toolkit, and Contacts
If it didn't work, then factory reset and start fresh (don't restore from cloud) it could be something from backup that conflict with MIUI

Thx for the tips I'll try them Edit: only had crashes on device setup
I did factory reset(4th time) and haven't restored from cloud yet, I̶'̶m̶ ̶a̶b̶l̶e̶ ̶t̶o̶ ̶p̶r̶o̶p̶e̶r̶l̶y̶ ̶u̶p̶d̶a̶t̶e̶ ̶a̶n̶d̶ ̶i̶n̶s̶t̶a̶l̶l̶ ̶a̶p̶p̶s̶ ̶n̶o̶w̶. can only update some apps already installed on the device and phone hangs when installing google apps that are part of the device setup.
I think this problem has to do with miui aggressive apps freeze/lock battery saver policies
Anyone knows how to disable that? I did disable miui optimizations and wifi throttling in developer settings (And no I don't have battery saver on)

I did factory reset(4th time) and haven't restored from cloud yet, I'm able to properly update and install apps now. But if I can't restore all my data from my account this phone is pretty useless to me.

I'm no expert on miui yet by try to lock google play store in the memory. You can do that in the recents list. Also make sure that all the needed apps have the right permissions (storage etc.).

PokemonGo - c̶a̶n̶'̶t̶ ̶i̶n̶s̶t̶a̶l̶l̶ was installed after update MIUI V12.0.2.0 (QJGEUXM)
Flud - can't install always stuck at 66% (25-09-2020 managed to install it today...dunno why)
Anyways I unlocked bootloader etc. Still can't update some apps like, messages, chrome and system webview
But what is important :
PlayStore settings -> scroll to the bottom and under Play Protect certification -> Device not certified
Is this normal?

Same thing happened to my device when I bought it, but I managed to install everything. All it took was just a restart.
Also, keeping your bootloader unlock will remove the Play Store certification, the only way to be certified again is to restore the stock rom again and lock the bootloader, otherwise you may encounter further problems with Google services in the future.

The apps eventually install/update, for some reason. Just wanted to find out why
