1) Hard Reset = Hold Vol down and power
2) As soon as the screen goes black, press and both volume buttons and plug it into the usb (can take a few tries if they is an error somewhere)
3) This should get you to download mode
once in download mode download the A50 android 10 firmware from sammobile [ https://www.sammobile.com/samsung/galaxy-a50/firmware/#SM-A505FN ] - be sure to change the model and network for your phone.
Now you are on stock android 10 [So many reasons to use this over pie - for twrp and magisk it has worked wonders]... Follow this guild: https://forum.xda-developers.com/galaxy-a50/how-to/guide-samsung-galaxy-a50-btc4-firmware-t4071817

Hey thx for the fast help.
I was tryed it for like 40 times and gave up to sleep a little. after that my Phone was dry agian. wenn i pluged in the dry phone to my pc while holding the vol buttons it finaly worked.
i was able to flash the phone with no problems back to a normal firmware but was still stuck in the same bootloop. but this time i was able to reach the menu to make a factory reset. now every thing works fine.
but i have an other problem now. Over night i opend my Phone and disconnectet the battery because i wasnt able to stop it. I accidentlly ripped a cable at the opening progress.
The phone still works fine but i want to know what i destroyed in case it was something important. i added a Image of a not broken one. i draw a smal red line at the point i broke it.

I think that flex cable is part of the middle frame wich connect the buttons and one antenna, how about power and volume buttons and network signal (try both sim slots)

Can't get into recovery mode

I flashed JG5, updated to modaco's r3 and then tried to flash mimocan's stall fix which killed my phone (progress bar stayed on 0 and phone went black).
Now I've reflashed JG5 and cannot get into recovery mode.
VolumeUP+Home+Power just starts up the phone as normal ( I have tried multiple times)
VolumeDOWN+Home+Power still gets me into download mode.
Any ideas?
EDIT: Managed to reboot into recovery through adb.
I have the same problem here.
I can enter in recoery mode only with abd or reboot widget ...
Anybody else ? volume up + home + power doesn't semm to work ...
EDIT : the pb occured when I flashed the JG5, and I have the same problem in JM1 and JM2 !
EDIT 2 : I manage to acces to recovery mode.
I pressed volume up + power + home and when the i9000 logo appeared I released power !!
i've had a bad flash with latest firmware, odin became stuck at "do not power off"
now i get the "cannot connect" icon and the device isn't detected when i plug in the usb cable.
i've installed both kies and usb drivers, but still nothing.
any ideas?
i actually get a com 7 usb serial port driver but the device isn't detected by odin. the drivers installed are default from microsoft.
10x.
Had this issue myself.
I disconnected everything. Restarted the computer.
Opened the back of the phone and removed the microsd card, sim and battery.
Put the battery back in. Placed the phone in download mode.
Started ODIN and entered all the files then connected the phone to the computer and flashed as per normal.

Exactly that!
If you don't get into recovery mode by pressing volup+home+power, you are just pressing them too long or short or alternatively didn't turn off the phone before trying it (not necessary but makes it a lot easier)

it worked, i think i was pressing them in the incorrect order or something.
I found I had to do it a couple of times to get it to work as well.
Just have to keep at it. Maybe my old fingers are not clicking at the same time.
Cant get me Gt-9000I into recovery mode & cant on usb debugging because pattern lock.
I've got an old GT-9000I which cant get into recovery mode with button combinations. The bad thing is phone is stuck in pattern lock as well. I forgot my pattern and phone is showing email verification for unlocking device which is also not working.
Is there anyway I can flash my device with altering some circuitry or applying anything.

Bypass custom OS warning to access recovery with broken volume buttons

Hello all, I've got a bit of a problem with my Galaxy S3 Canadian version. I am stuck in a bootloop and unable to go into recovery to factory reset to clear the issue. The reason behind this is because while I am able to boot into a warning telling me to press the volume up button to continue, I am unable to continue as the volume up button does not work/ (Oddly enough, the volume down button works to get into recovery with the power, volume down, and home button, but the volume down button does nothing on this screen while it is supposed to reboot.)
I have been able to install a custom recovery which supports touch, but I am unable to reach it. I have searched the forums and found a solution involving adb and fastboot, but I have tried this and both are unable to detect the device, presumably because samsung does not use adb or fastboot, the drivers are installed and all other things recognize the phone, including odin. I am able to reach download mode however, as I bought a jig a while back that has come in handy.
Thanks for your help!

The volume down, power, home is download mode. Recovery is volume up, home, power. Could you include pictures of your screen? Your other option is to replace the volume buttons.
Thanks for the heads up! I tried with volume up but the phone just gets to the screen saying "Samsung Galaxy SIII" and continuously reboots. Here's an image of the aforementioned screen:

Oh, alright, haha that's awkward. Do you know of any alternative ways to reach recovery without access to the main OS or the use of the up volume button? At this point, I've pretty much decided on selling this thing for parts on Craigslist. Thanks!

I would just fix it. Parts can be found for cheap. You might not get the price you are looking for. You might not find a phone for the same price. Is it a I747M or?
i747m. Will try and see how it goes, thanks anyways for your help!

Ouch a soft brick. Damaged recovery maybe?
Try a hardware factory reset again if you can:
Hardware factory reset (Using power and vol buttons when you can't run it from within Android 4.4)
Take your phone and turn it off – just press power button and select “power off”.
Wait while your device is shutting down.
Then, press volume down button and power button together until the LG logo appears on the screen.
When the LG logo is displayed, let go of the power button, keep pressing the volume down key and then press once more the power button.
Once you do that, on your LG G3 the factory reset menu will be displayed.
Press power button in order to agree and wait while the hard reset is being completed.
If you can't do that do you have download mode at least? If download mode can run your not fully bricked. And you can run the KDZ flasher, flash the tot and dll files again.

LG G3 Unbrick/Unroot (set to Stock ROM) stuck on Status 2
I had the same issue (phone stuck on Status 2) during stock ROM update. This is what I did to get it to work :
Unplug battery.
After a couple of seconds, plugged battery.
Repeated step that makes phone go into download mode (Volume Key up pressed while plugging into computer USB).
Computer continued downloading everything and finally made it to Status 3 (update is complete).
Rebooted phone. Everything works OK!

Lenovo Vibe Shot Z90A40 Cant Turn the device on after miflash completes successfully

Hi,
I am not getting Qualcomm 9008 mode even after installing and reinstalling the drivers manually or via setup
I see this under Other Devices in device manager
QHSUSB__BULK
Then I ran miflash it worked fine as per following attached screenshot:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But when I unplug device and turn it on it does not show any thing, just a long (2/3 seconds) vibration and done
So basically I cannot get any thing on my screen, Plz help me to get to recovery mode, as if I get till that point
I would be able to flash a proper stock ROM form SD Card
(I have tried the things after removing SD card as well)
it is fixed now
I resolved it, the Diagnostics 9006 mode problem happened to my device twice due to various reasons
in first attempt I was seeing a lot of read only partitions when I connected phone, it was solve using QPST/QFill
before resolving this problem I was able to go to Stock recovery almost all the times but was unable to flash
any thing from there even with the use of SD card
2nd time the problem was same, but this time I was not seeing any partitions in my Computer
actually both times the real problem was going to proper 9008 mode which I finally got to know how to do it from
following thread
http://www.androidbrick.com/lenovo-zuk-phones-qfil-roms-unbrick-guide/
I feel I shall put the text as well:
If you were on Lollipop : Phone must be completely off. Pressing �Volume Up�
key plug the USB cable in WITHOUT PRESSING POWER BUTTON ! Port will open.
If you were on Marshmallow : Phone must be completely off. Plug the USB cable in
and immediately press Power On button. Port will open.
Since I bricked from Marshmallow, so I used the Plug in Cable + Power button only to got
to 9008 mode and once there I knew I can make a come back, which yet came after a couple of tries
as one has to click immediately on Download button when Qfil can see 9008.
Actually I bricked my phone a whole lot of times even after my post thats because once I knew that it is just soft bricked and I can get it back somehow, I got the confidence and tried advanced things that bricked my phone again and again
And it was only the recent time (around 3 weeks ago), that I figured the 100% working 9008 method for my phone
actually u have to drain the battery completely out then it will get 9008 mode to do it u shall try turning your phone on again and again so that battery goes off
For example: Press Power button for a few seconds to turn it on.
Or press 3 buttons at same time (VOL+, VOL- and Power), then release only Power button when you get vibration. Then after 2 seconds release both VOL buttons as well (this is for going to recovery mode)
This way you can drain all battery of phone, and you will know when the battery is all gone when you will press the Power button and phone will not show any LED light or screen light, it will just vibrate and will be off
Now you connect ur phone to PC in following way:
If at bricking you you were on Lollipop (Android 5): Pressing VOL+ key and plug the USB cable in WITHOUT PRESSING POWER BUTTON ! 9008 will open use Qfil to flash the ROM u want
OR If at bricking you were on Marshmallow (Android 6): Plug the USB cable in phone, then connect cable to PC and exactly at the same time press power button (some times u dont need to press power button so try with both options). Then if you see 9008 mode in Qfil, then immediately press the Download button in Qfil
If you see Qfil error then repeat the above process to get 9008 mode and use miflash instead of Qfil miflash worked for me better than Qfil from such situation as Qfil often gives error in between
And when you get the flashing 100% then phone will either auto restart or you have to restart it manually Using Qfil it shows u message when it is restarting the phone, and I think using miflash it just says process 100% complete then u have to restart phone yourself
Remember at this point (after restart) connect your phone charger properly in a electricity power socket instead of PC as the battery was already drained so you need to charge the device while it shows the long booting process due to new ROM flashed.
Good luck,

Go into recovery mode (with the device powered off, hold Volume Down + Power) and you see what options are available. I'm not suggesting anything because I don't know the device, but I'll hint when I see a screenshot in recovery mode.

The image shows that the system booted into safe mode, not recovery mode. Can you check with the adb devices command how the phone connected to the PC responds?
Recovery mode looks like >this< video at 1:30.
