(My pc is ok it have all driver installed and odin works)
Is there anyway to solve.
Thanks.

reboot pc just to be sure.
connect phone and pc
on the phone in download mode screen, hold vol down and power till screen goes blank immediately let go and hold vol up and down to boot back into download mode. the letting go when screen goes blank to holding up and down needs to be fast.
now once back in download mode, is odin showing port number?
also make sure your using odin 3.13.3
if still no go, try uninstalling samsung usb drivers, reboot then reinstall and try the process again.

When I put cable in my phone it directly shows the logo....
Its not showing the battery

I tested my another Samsung phone to be sure that my softwares are working. And it's working but when I put my A70 in. Nothing happened

[Q] Phone displays on

Hello guys, today i have a problem with my phone... Yesterday at the evening connect my phone with pc, and put my phone in download mode (up volume + power), then i started a download of firmware from the net, but i got a call from my boss and he asked me to go work immidiately. I have forgot to disconnect my phone from the pc, and when i come back after about 6-8 hours, the screen was stuck, i have tried to turn off and on my phone, but screen was stuck. I have pull out the battery, and put it back again. Then i pressed the power button, and screen was stuck at that image (showed in the photo attachment). When i try to click any button, volume or power, that image just disappears for second and then showing up again. I cannot go to fastboot mode, i cant go to download mode, i cant boot up the phone, when i connect it to pc, odin recognizes it, but when i try to load a firmware on my phone, odin writes something about "waiting for connect your phone" - endlessly.
What should i do? Need help please...
Sorry for my english

Galaxy Tab 3 NO Power, boot loops when plugged in. Otherwise nothing Video attached.

Hi all, I've been using XDA for years since the original O2 XDA's and I have never had to post anything as I've always found my solution. I'm hoping somebody can assist me with a problem I have on this stock galaxy tab 3.
The device was brought to me after being thrown down the stairs. I replaced the screen and built it back up,
Removed battery connector and reconnected = nothing happens
Press power = nothing happens
press download mode = nothing happens
press recovery mode = nothing happens
Plug USB into PC = nothing happens on PC or tablet
Plug in USB mains charger and it displays battery charging logo but it doesn't fill or animate the fill then it starts the samsung boot screen. It reboots and continues to do this constantly and never ends.
I've tried two batteries and both batteries work in another tab 3 but neither batteries changed how the device works.
Thank you for any advice in advanced!!
I just received a Tab 3 lite (SM-T110) for repair, it's having a similar problem.
It does automatically turn on when plugged into charger or computer.. It is stuck on a bootloop, requiesting a Kies recovery. It does reboot when given the three finger salute (center button, volume down, and power) - it will not enter recovery mode though - same firmware error message). The device is also full off or full on, no indication of it's it's recharging or no - let the battery run out, it's off - else it's on (does not turn on or off with power button). I don't have any info how it got into this state - most likely power loss during a firmware update, but haven't ruled out other possibilities (ie bad rooting job, a custom ROM upgrade went wrong, etc). I'm not 100% concerned about cause, but hopefully I can unbrick the thing.
Anyways, I loaded Kies onto my computer and put it into recovery mode and plugged it in - nothing. Exit the recovery mode of Kies, and all of a sudden the program goes nuts trying to connect and disconnect from the device. Hmm... Okay, disconnect it, uninstall Kies, install Kies3 and try again - same thing except it complains the device is too old when the program leaves recovery mode - but same thing otherwise - does not show up in recovery mode, connects and disconnects at huge rate when not in recovery mode....
Hmmm...
Now looking at the screen, it does indicate (in the upper left hand corner) that it's in ODIN mode... So my next step I figure I'll try ODIN (although I'm researching ODIN at the moment as I haven't used it before (never had to unbrick anything from Samsung prior to now).
Okay, that was painless - downloaded and installed ODIN 3.10.7, and then downloaded the latest firmware from Samsung, extracted the firmware, added it to ODIN's AP line, then hit start to push the latest firmware onto the tablet. Good as new again.

Bricked my LGG3

Hello everyone,
so here's my problem:
Wednesday morning i took my phone out of my pocket and had a blackscreen. I tried to restart it and took out the batterie but i always got stuck in the LG Logo or a bootloop. Since i had TWRP and lineage OS installed, i tried to go into the twrp menu with the factory mode (power button + volume down) but after the "double yes" i always got a blackscreen.
So i went into the internet to fix it myself. I tried the "LG Flash Tool 2014" with the kdz. reset & the other Flash tool with the tot. reset. Both didnt recognize my phone. At this point, the only thing that worked was the download mode BUT not the recovery mode that usually comes after it. It just showed the download mode for some seconds and then a black screen. Later i noticed that my phone showed as a "qualcomm device" in the device manager, and the internet said that this was bad. So i used "Board diag" and "Smart boot diag" to fix it, but at the point where the device should have restarted, and the download mode should have worked WITH the recovery mode, i always ONLY had the 6 second download mode. After messing a bit with "Board Diag" i even got it to show up as LGE AndroidNet USB Serial Port in the device manager, which apparently was even more bad and only way to go back to qualcomm was to shorten the pins which i did. And it worked BUT now i was back with the qualcomm stuff.
So as you can see, i've prety much run i circles since wednesday... Iam now at a point where 3 different thingscan happen when I try to put my LG into download mode (volume up + usb cable):
1. Its recognized as a unknown device which is constantly connecting and diconnecting, so iam assuming my phone is bootlooping with a black screen.
2. The download mode icon shows on my phone and disappears after some seconds but my pc fails to recognize it.
3. Nothing happens and the screen stays black
When i only connect the usb cable, it shows a stuck charging icon for some seconds and then goes black. Connecting without a battery shows the "missing battery icon". I tried with 2 pc's, both having the LG mobile driver 4.2 and the qualcomm driver installed AND beeing in testmode. Both don't recognize the device. I also tried 2 batteries on my phone but it changes nothing.
I have a D855. And i know that my situation is pretty f*cked but maybe someone i able to help me anyway. Thanks alot.

Samsung Galaxy J6+ flashing crash - Boot loop endlessly

Hello,
I have a problem with my phone : Samsung J6+ (SM-J610FN/DS)
I have crached a flashing Rom with Odin and I'm sure it is because of that my phone can't start by pressing the power button.
Now my phone has the message : An error has occurred while updating the device software. Use the emergency recovery function in the smart switch PC software ...
The thing is that it is rebooting and looping without end every 2 seconds on that green screen with that message ...
Only thing I can do is, with the USB cable connected, when the green screen is up, I can push VOL down + VOL up and I can go in download mode.... Then I can push on VOL up but right after the phone reboot in loop again and again ...
Another thing is that without USB cable connected I can't start the phone.
What can I do ?
First thing, I can't start my phone if it's not connected with the USB cable.
Second thing, when I connect my phone with the USB cable, it starts automaticaly even if I didn't push the power button and it's looping and blinking and rebooting endlessly.
Also the phone don't seems to know how charging himself when USB cable connected.
Is it a Bricked samsung phone ?
If it is, how unbrick it ?

Have you got the issue fixed on you phone?
Since you can reach download mode - why not doing a clean flash with the correct firmware?

Cannot boot into download mode

Hi everybody, yesterday I was playing with my old Galaxy A50 trying to install a custom rom unsuccessfully.
I repeated the procedure three times installing TWRP and then Havoc OS but every time I tried to reboot from TWRP to OS I was stuck at the warning screen saying that the phone bootloader was unlocked and booting into download mode to reflash TWRP was blocked as it showed "only official binaries can be installed" (yes I installed Samsung disabler but still).
Still I was able to get the phone into download mode and reinstall the stock firmware as it seemed to be the only way to install and boot TWRP.
But at 4th time repeating the process I got frustrated, shut down the computer and left the phone on the warning screen still connected to computer usb cable.
Then I got back and noticed the phone was off as the battery died.
Indeed the battery died, so I put the phone in charging and after it reached 100% I tried to boot into download mode again to reflash stock firmware.
But here's the strange thing, I cannot boot into download mode anymore as pressing vol up+vol down while connecting usb cable, shows the lightning charge logo for 5 secs and then reboots infinitely with the same pattern.
If I force reboot by pressing vol down+power it shows the Samsung logo with the warning below it, then skips to another screen with another warning suggesting to press power button to continue (which does nothing) and after a while reboots to samsung logo.
So it doesn't seem it is bricked, it looks more like a battery controller fault, so I tried to detach the battery flex from the board, hoping it would reset the controller but it's still the same.
Also I tried with the flex detached and still no download mode is possible.
Was the download mode somehow erased? (if it's even possible considering it's the motherboard firmware)
If you need photos, videos or even a call on zoom, Skype, webex I would be glad to show you
same i got the same problem i can't find nothing for this when i press volume up and down and put the otg cable its simply charges but it gets stuck on the logo image there's no way to fix this but the only way is to open the phone,change the emmc and put one from samsung,close the phone flash a custom rom and you are done.
If you can enter recovery, do it. As soon as your phone gets into it, select the power off variant and then try to enter the download mode.
It seems like you did not unlock the bootloader, did you?
The bootloader Is unlocked i can't enter in the recovery because the phone locks on charging logo and its fully charged but when i try without charger It doesn't start.
