That's the problem..
My drivers are up to date.. I can connect my other phone and this is no problem.
Just the A50 will not connected or detected by the pc.

Does the a50 charge and does the cable transfer data?

The same cable works with the s20
And the A50 starts if I connect the cable.

No charge screen? Just straight boot to the Samsung screen and froze?

I Cannot Help You Fix Your Phone
Sorry
Samsung always does crap different. They integrated the nasty vertified boot but does not enable fastboot mode which allows disabling it. At least as far my knowledge reaches, your phone is just to me a fancy, glowing paperweight, although I know telling you that is heartbreaking.
Your options could really get up to:
Find, some other posts related, or senior members and developers who are helpful, or Google 'vertified boot Samsung bypass' as a last hope.
Define your A50 as obsolete, (maybe cry for your money then) sell it on ebay as 'parts / unfixable'. If you need the data protected, sell the body, screen, battery and dispose the motherboard in some known environmentally friendly way.
I don't recommend putting your hopes off, so I will provide some related posts from now on.
If you wanna get the data back, there is a (kind of hard) way to do it.
Unsolder your emmc chip and solder it onto a usb drive.
Also, replacing the EMMC storage chip may help as the corrupted data will be replaced, and maybe that is the answer of the problem but that requires high soldering skills which puts off most people.

[Q] Bricked Galaxy Nexus

Hi there! First of all I don't speak english very well.
My Galaxy Nexus hard bricked yesterday.
tl;dr no boot animation, no recovery mode, no download mode, no response from computer.
I thought it had just a low battery level, I found it turned off. So I tried to recharge it but it gave no signals, no battery icon, nothing.
After an all night long recharge I tried to turn it on, to enter in download mode or in recovery mode but nothing works. I also tried to connect it with my computer with and without battery, no response, no "OMAP" device found, no sound from Windows for plugging it in, nothing.
I found this thread here in xda, many people has been redirected to it and found their solution to the brick problem.
I tried to follow all the steps but when I plug in the phone and start the .bat file nothing happens, just stuck on "Waiting for device".
The phone is unlocked and rooted. I'm running AOKP JB-MR1 Build 2 and Franco Kernel for a month, never had problems with them, never installed other ROMs after that.
What should I do now? Should I try to do something or just bring it to a support center? The phone is still in warranty, there would be any problem because it has a non-stock ROM?
I've red about a jig to force the Odin mode, should I buy it? (I found this one)
Thanks for the help.
Have you tried booting into Odin mode

Yes, it doesn't work.
have you your warranty on it?
return it and get a new one
It's hard bricked and a JTAG unit may force it into download mode, if you send it in for warranty, chances are it won't be accepted as it was obviously tampered with and they would find out that your bootloader is unlocked and charge you more money than the device is actually worth to fix it.
I don't understand how it could of bricked if nothing has changed on the phone for a month or longer. Nothing was flashed recently so how can you hard brick the phone?

Yeah, that's why I'm not sure to send it in for warranty. So have I to try with a JTAG first?

I'm not understanding that too, I don't know what happened. Suddendly it stopped working. Maybe is just a battery problem, I'll try to use another one before bringing it to the shop where I bought it.
same happened to me, but I have an untouched phone with stock android. it worked well for over an year until today.
I see a lot of people having same issue, but they say that when connected to PC over USB the phone is recognized as OMAP.
for me the PC doesn't do anything...
any help? thanks

so right after I wrote that I plugged my phone into USB of my PC without battery. when I inserted the battery it started showing me the battery sign and I could started the phone. 3 minutes later it went black again, but the trick didnt work again.
any ideas? thanks
Try This !!
Arrange a 4 ohm resistor and try to attach it in ur usb plug port of phone ..it 'll force the phon eto go in download mode or say Fastboot mode.
then follow a tutorial to flash any rom..
its quite easy else ping me !!

Please could you explain a bit more how to go about this? I have a Verizon Galaxy Nexus in a somewhat similar condition. This one is recognised as an OMAP 4430 device. I downloaded OMAP Flasher, installed drivers and tried to bring it back to life but after running the batch file I get this error: Operation FAILED (Remote: : Driver init error 0x00FF8080 - MMC CONFIG FAILURE). Can the resistor trick work on this and if yes, how can I go about it? I am not faint-hearted; I think I can handle it if given the right instructions.
After I tried everything i could from the internet, I went to a shop and tested to see if the USB is broken - and indeed it was. I replaced the USB component of the phone and after that it started.
Thanks guys

[Q] T-Mobile S2 T989 - hardbricked / can jtag fix it?

I received an SGH-T989 that wouldn't boot. It had TWRP on it, so I was able to flash latest stable CWM. Upon reboot, it apparently became hard-bricked.
Currently, I'm unable to enter download or recovery modes. USB Jig does not work. There is no output on the screen, even when charging the battery. When connected in Windows (32 or 64), I get a usb error message: "This device is disabled because the firmware of the device did not give it the required resources. (Code 29)"
My question: Is the motherboard dead, or could a jtag repair fix it?
What I've tried:
multiple micro usb cables
usb jig
odin
keis
heimdall
Thanks xda!

That would be great! I did see the S3 fix that loads a debrick.img from sdcard - would that work with hardbricked? Windows wouldn't load the usb drive for my phone, complaining that the firmware didn't give the "required resources". So if the firmware is borked, I'm not sure it would be able to load an external img.
I couldn't wait, though. Sent it out for jtag repair :fingers-crossed:

Jtag should always do the job, unless there was physical damage done to the motherboard.

The t989 has great specs, only downside is its PPI (really low) if you still love it, I would wait if you want to send it into JTAG repairs, we are on the verge of unbricking our t989 without JTAG! Looks like we need someone with a working t989D though
I have been studying the other 'unbrick' methods, its definatly mind expanding, the amount of knowledge absorbed can seriously make you forget time n space.
If there is anything I can do / contribute holler at me.
Now ill tell you something weird so I flashed a rom not meant for T989D plus I did it all without being rooted. (if it matters) since Since the flash the phone doesn't boot into recovery or show a bootanimation, just darkness.Yet it felt operational in hand.
Once I plugged it back into the PC all I got was a constant notification of drivers that cannot be identified Also it keeps connecting and disconnecting the device.
None of this is weird until I installed OMAP flash and the T.I. drivers for which was used to fix my friends nexus. After he left I plugged my s2 to the PC still nothing. I looked away for a brief moment . Then i noticed MobileGo for Android popped on screen. Visually showing my s2 as an Alcatel rom.
just bizzare.....
The unbrick method on the S2 is a little different, but in General, at http://forum.xda-developers.com/showthread.php?t=2646310 after a little work, I resurrected a QHSUSB_DLOAD 9025 T989D to the point of ODIN and fully working Android OS working, just missing recovery.. Soon to follow in a day or so.

Hi, so I also have a hard bricked t989 galaxy s2 (tmobile variant) and I'm attempting to understand the instructions. However my phone has another issue...usb connection to the computer does not work, it hasn't worked since the micro usb port on the phone was replaced because the old one broke. So really the phone could charge but never connect to my pc as it cant be detected...so what are my options? If i create the sd card with the image, will i still need to connect it to a pc in order to force the phone into download mode? Please help...

[Q] Official software upgrade - probably bricked my galaxy grand :'(

Hi all
I got a notification of the latest software upgrade available for my device. I downloaded it and installed it. The installation process was shown to have reached 100% and then the phone screen went black and then did not turn back up. When I connect the phone to charger, I do not see any battery charging icon
I had my phone connected to the power outlet while I was upgrading? Is my phone bricked? Any way I can resolve this issue? My phone is out of warranty.
I have never ever rooted the phone. Not sure why would this happen with an official software upgrade.
Any help will be immensely appreciated
Are u able to enter recovery mode!

After successful flash the phone will reboot automatically and will stay on bootloop, while rebooting press and hols home+vol.up+power button. Then factory reset, wipe dalvik, wipe cache. Then reboot system..
Why not PDA? When i flashed stock rom i choose PDA and choose the file.
Auto reboot and f.reset time are the only checked boxes

SGH-i747m only boots to recovery mode with 16gb sd card

Hello, I purchased a phone off kijiji fully knowing it was not functional - For the 40 dollars my curiosity got the best of me; and if I can fix it well I can get myself a new phone for cheap. I was informed that this phone: Samsung Galaxy sgh-i747m had the latest update (not custom rom). The phone suddenly would not boot past Samsung logo and by the time I bought it, would not boot up at all. So after doing extensive research I decided I would give the 16gb class 10 sd card boot a chance. While somewhat of a success, the only thing it boots me to is this.
BOOT RECOVERY MODE (IN GREEN)
CHECK BOOT PARTITIONS
COPY FROM T-FLASH
BOOT RECOVERY
WRITE 159488 SECTORS
FLASH WRITE FAILURE (RED)
ODIN MODE (RED)
PRODUCT NAME: SGH-I747M
CUSTOM BINARY DOWNLOAD: NO
CURRENT BINARY: Samsung Official
SYSTEM STATUS: NONE
QUALCOMM SECUREBOOT: ENABLE
Warranty Bit: 0
BOOTLOADER AP SWERV: 1
I should note that with the debrick-SGH-I747M-UEMK5 image that I used, the phone will boot to recovery mode without holding any buttons(While Plugged in). It will also boot to recovery if it is unplugged and I simply hold and release the power button when I feel the vibrate. I have also tried volume down + home + power. Same thing. If I take the sd card out I cannot get any sign of life / no recovery mode.
The computer does not see the device at all, even in device manager as a random name. There are no signs of life on the computer end. ODIN also does not detect it even when in boot recovery mode. Will not boot to download mode. A red light comes on if I pull the battery out and plug in the usb cable.

No, I was contemplating making one or ordering one online but was unsure if that would make any difference. But I am willing to try anything even if there is a slight possibility it could work.
Where are you located? I recall seeing a thread on XDA about people that has a USB job for use by other XDA members.

I am in Thunder Bay, ON
I'm in Toronto which doesn't help you right now. Maybe order a USB jib and see what happens.
If you decide to sell the phone, let me know as I need to try and repair a phone that has a defective lcd and digitizer.

Will do. Going to build jig today and test it out
Another solution may be to have the firmware flashed via jtag.
You should be able to flash with Odin from there if I'm not mistaken. (Been a long time since I've been through this part myself). You may need to try different drivers, different cables, usb ports, etc.

Yea I didn't want to have to go that route if possible as my goal was to gain experience and knowledge from this little project. If I got the phone working then I would just replace my old Samsung infuse. I made the USB Jig using the 301K ohm's and it still does not work. I know the jig works because I tested it on my wife sgh-i747m and also on my infuse. Both of which boot into download mode immediately. My concern is there is something wrong with the main board because it really doesn't seem like it was rooted at all.
I am just going to see what I can get for it at this point, I paid 70 so would be looking to get at least 60

I have tried 5 different cords, and two different computers on all usb ports. Nothing
You said it'll boot recovery, is it stock or a custom one? Also, are you familiar with ADB?
When you plug it into the computer, is it detected by odin? If so, what does it say in the message box when you try to flash?
Look in device manager too. What does it detect the device as?

You have the Canadian version of the s3? Will you phone boot into download mode without the sd card installed?
Sorry, I have the SGH-i747. The phone only boots with the SD card and just stays in download mode. Odin doesn't recognize it.

What was the last stock ATT ROM on the phone? Can the phone boot into download mode without the external SD card?
When you connect the phone to you computer in download mode, are you prompted to install drivers? If you are using Windows, any unrecognized devices in device manager?
And don't forget to try different cables and every USB port on the computer. Cables go bad much more easily than most people think, and many charging cables cannot be used for data transfer.
I've seen a number of times where people found that only one of the USB ports would allow it to connect.
You might also want to try several different driver versions. (I'd start with the oldest that was release along with the S3.) You can find several in the link in my signature.

I am in big mess! Please help!!

I was doing some experiment with DriveDroid and now I am in big mess.
I think I messed up with drivedroid settings and I was not able to see my phone (oneplus 3 rooted LOS 15.1 ) on my computers.
I have tried different computers but all cant detect my phone.
I have tried drivedroid wizard, different usb systems, different usb settings and no luck.
I have tried uninstalling the drivedroid and still no luck.
The phone was going in charging mode only. Its was not going to MTP mode so I can see the phone internal storage in computer
I have tried to do factory reset also but no luck.
Now I mistakenly wiped data partition also and now the phone is with
No OS
No USB detection on phone while in TWRP
No OTG detection
No any ROM.zip file in phone memory.
When I am on TWRP and connect my phone in computer I am seeing same error message and cant see my phone interenal storage.
Now what to do? Any way to flash ROM ?
I am in big mess, and I dont want to spend money on new phone as of now
I hope someone will be my angle and suggest me something to recover and save me from this mess...
Crying out loud now...

Phone is not recognized in computer while in twrp mode so it is not able to connct to adb via USB.
Just get os flashed at OnePlus service center.
I did something same in my previous Samsung phone. I took it to service center and told em that it's not booting up and I don't know the reason. They flashed the firmware from scratch, charged me 250 INR and my phone was back to being normal.

I am not able to follow this as phone is not even coming in USB mode. So its actually soft bricked because can go to twrp and fastboot mode and booting up without OS but USB is not able to detect on my computer.
now the service center guys saying I need to change the motherboard which I dont think is the issue, mother board is not going gone for sure as I can boot up in twrp and fastboot mode. its just may be the usb host controller gone.
Cant decide if I should go ahead with mother board replacement at cost of 10k INR ( phone cost was 28K INR) .

If you use the Method 2 of the Unbrick Guide, you don't need normal adb/usb mode recognition. Follow that guide scrupulously and step by step. Don't skip any and don't rush.

I even tried that but somehow it is not even recognized as QHUSB_BULK device.
believe me I have tried all things to revive the phone but its not hard brick in my opinion, it can boot into twrp but the when I connect the phone in computer it shows the error message I shown as attachment in my first post.
yes, I have tried 2 different computers and few usb cables.

Your phone need not be hardbricked to use the Guide. It will work even on a normal perfectly working phone. If your phone is not recognised while following the Guide, it only means one of two things: either it is a hardware fault or you are not following the Guide properly.

tried to follow the unbrick guide on windows 10 but phone is not seen as QSBULK device in device manager.
I am going to try on windows 7 as few post said that windows 7 would be better for unbricking than windows 10.
finger crossed, right now flashing windows 7 live iso on USB.
so finally I am declaring my op3 as hardware failure as one of my other phone (yureka) easily identified as 9008 mode in my computer but my op3 is not. so all drivers are installed correctly but somehow my op3's usb hub is failed.
i guess time to move on..
thank you everyone for spending time to help me. it really is supportive and encouraging...

Although I bought 6T now and am kind of happy with that, but I am still missing my oneplus 3 and want to experiment on getting it revived.
By any chance someone can help me answering my doubts.. I would be greatful..

2. Is there any way I can turn on the wifi from within TWRP and so I can connect to phone via adb over wifi/tcpip ??
Thank you all in advance.
