WRecently i bought a samsuung galaxy s3 off of the internet and when it arrived i checked to see if everything was good. when i took the back off the sd card and sim card reader were broken off. so i turned the device on and it worked perfectly. started to root the device and when i tried to download supersu binary a notification popped up and said "knox is installed on this device,this can cause root access to be limited. would you like to remove knox?" when i did that the phone tried to reboot and then it was hard bricked. the only thing that works is when i plug it into a computer without the battery inserted via usb cord and the charging light appears then my computer tries to install the driver for it. after about 20 seconds the light turns off and my phone disconnects with my computer. Is there anyway to unbrick it by using a computer and usb cord? please help
Hello and thank you for using XDA Assist.
A little more information is required in order to properly guide you.
What carrier is your S3 for? Or which model S3 is it that you have?

Hello. Newb here so sorry if i make lots of mistakes.
I have a Samsung Galaxy Note 10.1 (2012) n8010 that is stuck in a boot loop, only flashing up the Samsung note logo then rebooting.
I am able to get into Android system recovery and Odin mode on the tablet.
It reads the SD CARD.
I have wiped data,factory reset and wiped cache partition.
It will not connect to my PC (tried 3 different ones) via the usb cable. I have the drivers installed via the Samsung_Galaxy_Note_ToolKit but the PC's just say USB Device Not Recognized unknown Device Hardware device not connected to this computer (Kies is not installed).
So i cant use the PC to connect to the tablet to use the tool kit or ODIN to flash any recovery.
Does this mean its most likely a hardware problem?
Faulty cable?
Is there a STOCK/CUSTOM ROM that i can install using the ANDROID SYSTEM RECOVERY via a .zip file that i can put on the SD CARD that will pass the signature verification to set it booting normally?
Thank you in Advance for any advice or suggestions.

I have seen this condition a lot lately.
How old is your Note 10.1, do you have the original factory cable and what condition is it in?
Not being able to connect to your computer is not good.

I bought it 0ct 2012 so its passed the 1 year warranty. Haven't contacted Samsung yet.
If it becoming common then is a mass complaint of all the effected units in order?
The cable is the original factory one. Seems fine on the outside. It charges normally and the PC sees it connected but just as an unknown device.
Tried to connect with the Kies (after downloading and installing) not still no connection.
Might try connecting it to my sisters Mac book tonight.
Buy a new cable?
Any repairers in the England sussex area to fix if worst comes to the worst?
Thanks

I had to install the 4.3 firmware on my S3 since it got soft-bricked, but it seems that even though I installed the Samsung USB Drivers and installed Odin, my phone won't connect to Odin. I tried using different charging wires and different USB ports, and that doesn't work either. Even my friend's phone, which was an S3 as well, managed to connect to Odin with the same charging wires. Is it something to do with my phone? I need help with this.
My S3 updated to 4.3 (locked bootloader) and I can't make it connect via USB, it won't connect. I've tried everything, every link I can find, reghacks, drivers (countless installs/etc). I know what I'm doing, I've been using computers longer than a lot of posters here have been alive.
The thing is the device isn't telling the PC what type of Hardware it is, let alone the PC having drivers. I actually think my phone is toast - I'm glad it still charges and you can (if you're not rooted) root via Towelroot without a PC.
Good luck.
Dear,
My Galaxy S6 SM-G920F with lollipop 5.1.1
AP : G920FXXU2BOG8
CSC : G920FOJV2BOG8

The pc doesn't recongnise it on device manager (i have a win 7 pc), the phone however react as pluged in a charger.
their is no mtp or mass storage switch on notification.
i have reinstall the driver of samsung several times with smart switch & also made it manual by suppressing directrly the samsung usb driver from programs on control panel then reinstall it but no hope.
I can't figure out eitheir its hard or soft.
i had change my cable & also test my pc with another Galaxy s6 it works fine, but mine no.
i have made wipe cache / factory reset also made an initialisation from parameters the phone is formated but not recognised by the pc also test it on another pc but the same behaviour windows pcs doesn't recognise my phone.
However, i figure out that when its on the restore mode (volume down + lock + home) the pc recognise it by Odin and smart switch.
i install the same rom on it also made an emergency restore with S/N and model and the process completes fine with smart switch and i saw the donwload progress bar completing on my phone.
but still i m stuck its not recognised please help !!!
i tries to use *#0808# and its on AP / MTP + ADB but no hope
i plug it on ADB android studio but the device list is empty :'(

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.
Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem
i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.
Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you
I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?

Picked up a used LG Volt from eBay for cheap, seller said device is user-locked. First thing I noticed is this is a Boost phone and there is a Sprint sim installed. Thought someone might have been monkeying with the internals. The phone is pattern-locked. I have tried every conceivable combination of button presses/holds and the device will NOT enter recovery mode. All I get is the LG logo coming on and the notification light glowing, then the logo and light disappears, then the logo comes on for a couple seconds then back off again and keeps repeating this cycle.
I connected it to my PC but, since I can't unlock the screen I can't set the phone as a removeable drive and it does not connect to the PC. I have installed the LG Drivers and tried to put the phone in DL mode, however, it is still not recognized by the PC. If I open up device manager on my PC and then plug the phone in the device manager rolls up and back down again like it is trying to figure something out, but the device still does not show up . I have installed/uninstalled the drivers and rebooted my PC several times in hopes that it would connect. I have tried a couple of Android managers on the PC but they don't recognize the Volt either. I have booted the PC into Linux and tried to work with it there but, again, it is never recognized. I have read several post concerning flashing in DL mode, even installed LG Flash Tool, but since the Volt isn't recognized the procedure comes to a halt. I read about ADB but I can't unlock the phone to set debugging and, I believe, the phone needs to be recognized by the PC.
If I could just get past the pattern-lock or get the PC to connect to the phone I feel I might have a chance fixing it.
