Hi,
I tried to install a custom ROM using TWRP and when i tried to reboot it, it said:
"No OS installed"
I rebooted the device anyway and it now bootloops the Boot Animation and i am unable to access download or recovery mode by the button combinations, I am also unable to access the device using the PC because it keeps rebooting itself.
What do I do to recover this.?

so you can't get into to twrp? what rom did you try? did you wipe before flashing the rom? if so what did you wipe? did you make a nandroid backup?
 
I am unable to access anything on the device, OS, TWRP, recovery mode, download mode ect, I tried using a Lineage OS ROM, I created a backup using TWRP and i wiped both cache partitions, data and system partitions.
 
Welcome to the forum @GlitchedFolx, :)

Again, I want to confirm you are using the Galaxy Ace. The files and processes can be very device specific, and using the wrong ones can lead to a permanent brick.

I think it would be, I was researching the device, because i live in Australia, and apparently the device i have, Samsung Galaxy Trend GT-S7560, is also known as Samsung Galaxy Ace 2.
 
It would appear the S7560 is the Galaxy Ace II X where the I8160 is the Galaxy Ace 2. The aren't exactly the same device. :confused:

I'll have to defer to some of our resident Samsung experts on how best for you to proceed. The good news is Sammy's tend to be pretty resilient, so hopefully someone can point you in the right direction.

ok no twrp.....i you will most likely need to flash a firmware made specifically for your device. go to sammobile firmwares and make sure you download the correct firmware for your device. you will need odin installed on your computer to flash the firmware.

How do i complete this task? I have Odin and the correct firmware for my device already but I cannot access download mode to install.
 
It will either turn on the back light for about 3 seconds before restarting, or show the Samsung Galaxy Trend LOGO for about 3 seconds before restarting
 
if you can't enter download mode then, you might want to try using adb commands to get into download or even fastboot.

adb guide:

if you can get to fastboot, you should be able to get to twrp and no need to try the firmware.

but if you want here is the guide to get to download mode via adb.

granted all this does require usb debugging turned on on your phone (hopefully this was done before the bootloop.)
 
If it is a windows device, make sure the drivers are installed correctly. I haven't done this in years, but Windows was finicky. If you have a *nix box or boot stick it makes it easier.
 
I have installed everything correctly but the device isnt detected by the ADB, it also is shown as SAMSUNG CDMA Technologies under the Devices tab on my Windows PC

i understand, but drivers and anti-virus programs can create communications issues with your pc and phone. it could also just mean that the loop is not allowing for the connection to be complete as well.

unfortunately this is the extent of my knowledge. if you can't use adb, and flashing a firmware will not work, i'm not sure what other options you have.

....maybe time for an upgrade?
 
This is what is shown in Device Manage by the Ace II X

I don't know if this changes anything, but it turns out that every button combination using the power button when the device is not plugged in, shows the Samsung Galaxy Trend LOGO, but the download mode combination just causes the back light to come on, like it is trying to load into download mode or something.
