Miui caused a major brick

Hi, I own a Galaxy S2 SGH T989 and I wanted to get the H1ve theme, so of course, I got miui. Right after I flashed it, I kept getting complaints about applications crashing, as well as the ics keyboard. Now, my phone won't even turn on. I've tried all ways I know to reboot (power button, volume and power, battery out and in, and all of that in the charger) and nothing works. Does anyone out there know how to turn on the phone. I just want to be able to factory reset on it. Also, when I try to enter download mode, the computer makes weird sounds at regular intervals while I hold down the phone keys.

ODIN flash back to stock. Make sure you have a battery while you're going into Download mode.

Are you doing the correct key combos for dl mode, vol down and power for 3 seconds then release the power button and keep holding vol down

[Q] I have a black screen after trying to root my Galaxi S3 SGH- I747M

I was in the process of rooting my Samsung S3 with Odin3, everything was going well, I was following the steps from theunlokr.com .. it looked like all the processes were done but at the end the screen never came on. I keep pressing the power button still don’t turn on. I hold the 3 buttons at the same time (Vol Up+Home+Power) nothing happen.
I press the on/off button and it plays the start up ring shows the Samsung logo and then it goes black.
Can anyone help please, I hope I can fix it ASAP, need my phone for work. Can't understand what went wrong.
Need your help
Thank you!!

First mistake was using a site other than XDA to root your phone. Pull the battery and hold the power putton for about ten seconds. Put the battery back in, hold the down volume button + the home button + the power button until you feel it vibrate and then let go of the power button while holding the home and volume down buttons. It should go into download mode and ask you to confirm by pressing the up volume button. If this works then using Odin on the computer to flash back to stock rooted.

Some solid ROMs include: CNA (codenameandroid), Kyan, CM.
I used to use BlackJelly as my daily-driver, but couldn't do without the AllShareCast functionality, so I'm back to stock-rooted, until I find a ROM that both looks awesome and supports AllShareCast.

well, if you can't power you M8 with any buttons combination i think you might have to send it to repair service...

Do you see the charging light at all?
Try plugging the phone into the pc via usb. Press and hold volume up and power until you hear a ding on the pc, might take a while.

I had the same problem after I did a dirty flash of a new ROM. Phone went black and didn't want to reboot anymore. What I did was to connect the phone via USB with the PC first. Then I tried combination of holding the power button for 20 sec. After that holding the Volume up key first then pressing together with the Power button and also hold it for 10-15 sec. After cycling that for 2-3 times finally my phone rebooted. I have no clue why but after that I was able to jump back into recovery and reflashed the ROM with full-wipe. Then everything was ok.

unplug phone, vol up and power for 11 seconds, let go of both, vol down and power to enter boot loader, then choose reboot. Must be unplugged for this

Do you use TWRP recovery?
Sent from my HTC One_M8 using XDA Premium 4 mobile app

Yes. Version 2.7.1.0.

My phone went black and wouldn't do anything after I clean flashed a rom. I just left it alone once I established it wouldn't do anything and it came back on its own after a while. I was using twrp 2.7.1.0 also. I have switched to Phil's touch recovery to see if it happens next time I flash a rom.

Did you make a nandroid backup before u flashed viper one? If u did enter recovery by rebooting holding down vol down and restore your backup. Or flash your carriers stock firmware. Check the back to stock thread for info on that.
If that doesn't work it's a hardware issue and you should check your warranty and get a replacement.

Thank you guys for the help and for everyone coming together to come up with solution it is deeply appropriated my M8 was finally able to boot it up I plugged phone on the charger and directly to the power outlet on the wall and hold the volume up + volume down + power bottom all 3 keys at same time for 20 minutes and released all key at the same and left phone on charger over night for 24hrs and phone was able to boot up

I think you only need to hold Vol Up + Power for a few seconds and it should reboot.
Mine did the same thing once and that's how I got it to restart.

True. Power + Vol Up is a reboot, basically a simulated battery pull (for phones that have a removable battery.
Power + Vol Down boots into bootloader.
Power + Vol Up + Vol Down is not any button combo on this device, that I know of. This is perhaps a button combo for another device? Care should be taken to only do known button combos. Although I don't think there is any "harmful" button combo on the M8; on my old One X (EVITA) folks would mistakenly do Power + Vol Up to go into bootloader (correct combo is Power+ Vol down) which erased the ROM and sent the phone into Qualcomm download mode, which would probably give you a heart attack!

[Q] Sumsung Galaxy Tab S 10.5 (SM-T805) screen went black

My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn’t drop and hit by anything…i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life

Are you able to get into download or recovery? I've never heard of something like this before. Maybe go ahead and let it die and then plug it back in and see if you can get into download mode by holding home+power+volume down then re flash your stock firmware or whatever you were using. Or do home+power+volume up to get into recovery. If you still have stock recovery then you can just do a factory reset right from that but if your using something TWRP then your still going to need to flash something after wiping your data.
Not sure how else you can get it to shut off since you can't see it. Even knowing where the power menu is once you press the button it would still be tough to hit the right thing. I'd say let it die. Maybe someone else can come shed some light. Of course it could be a hardware problem as well. I'm leaning toward software still though.
If your still completely stock I'd say let it die and get into stock recovery. Home+power+volume up and then wipe data and do a factory reset. Now if the screen stays black after its off and you've plugged in the charging cable then I'd imagine there's a more a serious problem going on.

Yes I am waiting for battery to be completely drained out. I will try your method once the battery is completely dead.
thanks

Your welcome let me know how it goes. Will do my best to help.

I don't have my tab with me right now but can't you hold power button for 10 sec to force a reboot? All Android device I ever had could do that.

Doest work on t805 holding powerbutton, just hold the buttons for download mode and that will force it to reset and prompt you to press volume down to cancel volume up to continue...hold for 30 seconds, and if nothing appears let go and just press volume up once, still no joy then pop back cover off and unclip and reclip battery if your brave, thats what i did before i new about this quicker way.

How to run the battery completely down..? its still active and on... though not showing anything on screen.
Is there any quicker way... ?

To do a hard-reset on these Samsung devices, you need to hold Power + Home + Volume Down until it reboots. On every other device it's just Power. Some it's Power+Home. For some reason Samsung likes to be different.
Or if you have previously enabled USB Debugging, you can plug it in to your computer and do an ADB Reboot.

Power + volume down + volume up works for me as reset.
