Device not detected with Computer - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hello,
I'm posting to XDA Developers today because I'd appreciate to get some assistance with a Samsung Galaxy A3 (2016) device.
A few weeks ago, a custom rom had been flashed but it unfortunately failed for some reason and now the device is stuck on a bootloop (Stuck on the Samsung logo), and it seems that it doesn't have any IMEI anymore (Field empty).
However, I can still access TWRP and the Download Mode.
The problem here, is that my device is not detected by the computer. When I put the device on Download Mode and connect it, Odin doesn't show it (Which would mean that the device isn't detected by the computer).
Also, when I put my device in sideload mode (With TWRP), it isn't recognized as well.
I've tried to reinstall the drivers but nothing worked.
Thank you all in advance for all your help,
Have a nice day.

[Q] Soft bricked I337 isn't recognized by pc

I'm on a rooted I337 that has been factory reset and under normal boot originally told me that normal boot has failed and was stuck with downloading.... but now tells me to select recovery mode in Kies also Download mode is still accessible. Before the crash I was working with a towelrooted 4.4.2. The problem is that nothing I do allows my computer to recognize it, It tells me that the device has malfunctioned and can't be identified. I've changed usb ports and cords and uninstalled/reinstalled drivers. Kies and Odin don't recognize it, but when I took it to a phone repair shop they were able to push a file that changed the normal boot error to what it is now, he gave it back to me to mess with and I could fix it if I could connect to it. Any help with this would be amazing
Thanks in advance
My I337 just got soft bricked earlier today, I made changes to my build.prop file to make it appear to be a Nexus 5, and rebooted just fine. I initially made a backup of the stock build.prop, so I decided to revert back to the stock file. when I rebooted, it gets frozen after the samsung screen and vibrates on any button press. I can boot into download and recovery mode, but I am unable to access the device via adb or kies.

Help trying to install stock bootloader

Hi people,
Long time ago installed TWRP on my samsung galaxy s5 SM-G900f so i could install a custom rom but never got around to it. Recently have realised that i can't update the OS on my phone due to having unauthentic software (or similar term) installed. While trying to reinstall the stock bootloader for android my phone got stuck on a loop of the TWRP logo and will only let me boot into download mode. After researching online I found out that i can stop this by installing CWM which will replace TWRP. Installed odin and everything on my laptop only to find my phone now won't be recognised by my PC and I am therefore stuck on what to do next?? (it would connect before this happened)
Any help will be hugely appreciated, thank you in advance!!
Get a stock ROM from sammobile .com firmware section, put the phone in download mode, and flash with ODIN 3.10.7

Sorry for the late reply and thanks for the advice, I have tried that but my laptop won't recognise the phone. I believe i have the correct drivers installed as it used to connect fine. I can put it into download/odin mode but i can't even locate it in the device manager let alone ODIN 3.10.7. If you could link me the correct/official drivers it would be much appreciated as all the one's I've tried have the same result.
Grab KIES3 from samsungs site, that installs the drivers, although windows always seems to install them for me automatically when I connect the phone

You can try fixing the phone with KIES before ODIN too if you want (Firmware recovery)
Phone has to be in Download mode (Volume Down & Home & Power) to flash from ODIN
ODIN will show a port number at the top when it sees your phone, as seen here with COM6 in blue

I've just installed kies and tried both ODIN and emergency firmware recovery but still neither recognise the phone, on Kies3 i get to a menu stating "list of devices requiring emergency recovery" and the box is blank (phone always plugged in, in download mode)
In odin no COM port is recognised, no text in upper boxes
Use a different PC / Cable
Tried both, used 3 different cables and 3 different pc's (2 windows 10 and 1 windows 7) after installing kies and odin on both still got same result as on my laptop. Although on windows 7 after i waited several minutes for the box to light up in odin a message came up from windows saying that no device driver has been installed for "unknown device"? thank you again for your help!
Seems strange that multiple PCs can't see it, there are some samsung drivers kicking about you could try, if I can find them I`ll link here

SM-G935FD Bricked... Sad...... help pls

today i made a very stupid mistake while i tried to root my S7 edge.
I put the phone to Download mode and installed twrp-3.0.2-4-hero2lte.img through Odin FIRST,
before installing CF-Auto-Root-hero2lte-hero2ltexx-smg935f.tar
It was a really careless mistake, really stupid..
what happens now is that the twrp is not installed (cant load into the twrp recovery). and it is stucked at the samsung s7 edge screen.
the phone can still boot into Download mode, but my computer cannot detect the device anymore.
it only recognises the phone as "unknown usb device (device descriptor request failed)"
- i tried with 3 computers (all running windows 10), 3 different cables, all wont work.
- battery has been fully dead and then re-powered on
can anyone help me with this please? i will donate to your paypal if you can help me fix this problem............
Have you tried to switch the cable / usb port and use the emergency recovery on the Smart Switch software?

galaxy note 4 stuck at (RECOVERY IS NOT SEANDROID ENFORCING) not recognized by ODIN

Hello,
I have a galaxy note 4 that was working fine. First the phone couldn't be recognized by any laptop as it showed USB DEVICE NOT RECOGNiZED.
When this happened, i tried flashing CWM using my phone only because it didn't show on ODIN, using FLASHIFY. i downloded a CWM.img file and flashed it i clicked continue, the app asked me if i wanted to reboot the phone, i said yes, then this happened. My phone now is showing me the samsung logo when turned on with RECOVERY IS NOT SEANDROID ENFORCING in red on the top corner. i tried factory reseting the phone, but it wont boot into recovery mode to factory reset it, it only shows the logo and (RECOVERY IS NOT SEANDROID ENFORCING). when pushing POWER button + HOME+ volume down to go into downloading mode, the phone does so, but when connected is showing me again USB DEVICE NOT RECOGNIZED, it's is not recognized by ODIN, every other phone that i tried this on is recognized by odin and by the PC . i have tried reinstalling the samsung drivers several times, unistalling USB BUS, changing cables and using original ones, changing laptops and PC, kies, heimdall gremlin remover and nothing, the phone is not recognized by the PC as it shows in device manager as (unknown usb device (device descriptor request failed)). so anything that can be done using connection to PC is out of question because IT IS NOT RECOGNIZED BY ANY PROGRAM.
At first, i thought it was the micro USB adapter not working correctly or maybe having bent pins as it was charging but not transfering DATA, so i took it to a repair shop and changed the port completly, but NOOO THIS WAS NOT THE PROBLEME, the phonse still could not be recognized...
I have already succeded in rooting the phone several weeks ago without having any problems.
My probleme is that my phone is not recognized by odin heimdall or PC, it can't boot into recovery mode to do a factory reset, and is stuck on (RECOVERY IS NOT SEANDROID ENFORCING.)
Please help, i have TRIED EVERY THING !!!!! :crying::crying::crying::crying::crying::crying:
bro, you need to change the connecting cable, got myself at same situation & same error. I changed my usb cable, put note 4 in download mode, reinstall samsung usb drivers and odin detects it, installed stock rom & its working again. i wanted to root my galaxy note 4 sm-910f, i tried several times with different odin versions, used CF-Auto Root but it got stuck at bootloop every time i do with same Seandroid enforcing message.
nop, didn't work..

S8+ SM-G955FD Bricked Only Download mode. Unrecognized USB device

Model Number: SM-G955FD
I Think i bricked the phone when i installed a TWRP update by flashing the twrp file as an .img file after renaming removing the .tar extension from the file. Currently im stuck in a bootloop where i the device shows up as an unrecognized device in windows when im in download mode. When Booting up i get red Text saying " Could not do normal boot. Invalid Kernel Length"
For those who would say: "Install USB drivers" --> The usb drivers have nothing wrong with them, i tried out another similar phone ( SM-G955FD ) and it works, i flashed stock, flashed TWRP, no problem with that other phone. But when i Insert the bricked phone with it on Download mode, all i get is that its an unrecognized device, device descriptor failed. (This is ever since a long time ago, Even OTG doesnt work somehow, but the device charges fine, and when i use my external SSD with a USB C to USB C wire it shows up).
For now What i have done is:-
I Tried to boot into Recovery -> Doesnt work, its stuck in a bootloop (I think its because i flashed the TWRP file as . img into the recovery Partition).
Booted into Download Mode -> It works
I Opened up the Phone and swapped out the Motherboard with another one from an S8+ with a semi functional Screen. Download mode works, phone works fine, nothing wrong with it, board is just old and i would prefer to fix the other one
What works:-
Download Mode
the USB port has nothing wrong with it. i Swapped in another USB board from a similar phone which shows up in odin and it still would show up.
What doesnt work:-
Recovery mode Doesnt work.
I believe its a Kernel/Software issue. Share your thoughts on this.
For now, i am running the phone on an older board from a phone with the same Model Number SM-G955FD with the Original Parts except the Motherboard. Even though i am somehow fine, i do not want the other board go to waste.
