[Q] No download, no recovery

I can't get past the Samsung logo. I cannot boot into recovery or download. What can I do? I've searched and read an no go with any of those solutions.

does it actually boot to android or gets stuck at logo
does it stay at logo forever or reboots after about 10secs, if reboots then its a stuck power button

Stuck at logo, no reboots. It doesn't come on when battery is taken out and put back in, so not stuck button.

if it boots u should be able to get into download/odin mode, how r u trying to get it into dl mode as i think ur doing it wrong, keep trying or maybe buy a usb jig as ive read that it will get it into dl mode but i havent tested that out

How to enter Download Mode on Galaxy S2 Skyrocket:
First of all, know that you will not use the Power button at all.
Connect your USB cable to the computer, but not to the device.
Now, pull off the battery from your device, and then place it back.
Press simultaneously the Volume Up + Volume Down buttons. With the buttons still pressed, connect the device to the USB cable.
The phone should turn on now, and a screen with a yellow triangle and a warning should appear on the screen.
Let go of the Volume Keys and press Volume Up once to enter Download Mode.

Nothing works, up, down, both same time, nothing. This started when I used Flashify to flash newest twrp .img. I think it's hosed.

recovery flashing should not interfere w/dl mode unless you flashed it for a different device which would of hard bricked it which yours is just a soft brick.
i dont think i ever seen a soft bricked i727 not being able to recover.
go through the ts for odin in my stickies
does pc see anything connected when phone is plugged in and booting
i would hazard a guess at a bad cable, usb port on phone or pc.
try just the volume down button b4 connecting cable, thats a rogers phone technique but you never know it might work if u have not tried it.
if all else fails a cheap usb jig might help

I've had USB cables in the past that transfer power perfectly well, but don't work to transfer data at all. Before considering your phone borked, I'd try a different cable, maybe a different port on your computer as well. I've taken Skyrockets right to death's door before, but even after frying them to one stop short of Hard-bricksville, Odin was always able to read them.

I tried a different call and port. I guess this thing is hosed. Thanks Flashify. I should have just installed a twrp zip.

Z3 won`t charge via USB

I have a Z3 which won`t charge from anything other than magnetic cable.I tried holding volume up and pluging the cable, only blue light shows and nothing, tried holding volume down, flashes red green blue and nothing again.When i connect it only with usb phone starts with a big battery symbol but doesn`t charge...tried holding power+ vol down and vol up again nothing tried pressing the reset button near the sd slot but again no connection.Bad part is that I don`t have any drivers for it on this PC but still it does not connect...

What version of android you are at are you using stock or aosp rom or stock or custom kernals both things can affect your charging in your phone. You can download drivers from the Sony,s website and can start flashing stock roms the charging part can be the software or if you have a broken connector on your Xperia Z3

It`s 6.0.1 version, but my PC does not recognise the device...

Then my friend you are in a heap of trouble. Well sort of two more questions i need to ask your question is confusing me
Q1 can your device boot to the OS ?
Q2 Have you tried fast boot if not flash an custom recovery like TWRP
If you have the case that your phone does not boot would not detect or be recognized by either Flash mode or fastboot mode then your phone might need some work

Please help me

Hi
I've made a bad mistake which I'm hoping people can help me with. I tried updating my phone wit MIUI 8 as I had an issue with my battery. My updater app on my phone was not working so I downloaded zip file and tried doing it manually from the app. Then my phone just turned off and I'm unable to turn on or charge. None of the button combinations work and when I plug in to my laptop through usb port I get a message saying it doesn't recognise device. I've tried using unlock function on website but get error messages in chinese around ip address to malfunctioned phone number so no luck there.
Appreciate any help as I had a lot of information, apps and data that i would hate to lose. I lost my wife 3 months ago and I have some precious memories on that phone. I know I should have done a backup beforehand and that was stupid of me.
Is there anyway i get can my back in without losing data. if not then anyway at all to get my phone working.
Thanks, from a very down MI4C user

Try holding one of the power buttons(don't remember which one) and plug in the cable so the phone boots into fastboot mode. If you manage to get into fastboot boot TWRP and copy your files straight from it as it has mtp support. If your PC sees your phone as an unrecognizable device there's a big chance you can recover your data. Last hope would be to use a modified usb cable for edl flashing although this way you'll most likely lose your data.

Thanks, first suggestion doesn't work unfortunately. I have now been given permission to unlock bootloader but problem is the device is not recgonised due to usb issue.
So I cant turn on, won't charge etc and none of button combinations work. Has anyone encountered the issue with usb before. Unsure of 'modified usb cable for edl flashing'. All very frustrating.
thanks for any help

Anyone else have any ideas. Desperate here without my phone and important data

Have tried everything at this stage...utter despair. My phone just won't turn on or charge or enter fastboot mode etc
Anyone please help

The modified USB cable that I spoke of is used to force boot the phone into emergency download mode. It's baisicly a last hope flashing method that should work regardless of how broken the phone is. The only downside is that using this mode you only can flash via miflash and this will wipe your data. As for the cable you can either make one (look for deep flash USB cable schematic, it involves swapping 2 wires) or just buy one. Once you get into edl just follow the unofficial bootloader unlock guide to flash the 6.1.7 rom as it is flashed in the emergency mode.
Edit: whenever you plug your phone into your PC does the screen or led diode light up at all? You can also try holding vol- and power button and plug the phone into a charger (not PC) to see if it will respond at all. Charger gives more current so maybe it will force the phone to boot.

Thanks Adi. I don't think I will be able to make one. I've seen some threads elsewhere about getting into EDL mode, do you always require modified cable to do so?
Nohting happens when I plug it into PC, no lights etc. Tried charging using normal power supply but nothing happens either. Have even tried connecting to powerbank overnight but no power is taken from it.

So there is no "unrecognized device" popping up in windows anymore?
If so, let the phone lie for 1 more day (without connecting any power sources to it). Afterwards charge it (with a normal charger and a cable that works for another phone) for about 2 days (or until you see the notification led charging). if nothing happens you can try a different charger or an usb port for another 2 days.
If your computer recognizes the device ("unrecognized device" or just any reaction by connecting the phone) try to reinstall all the drivers (xiaomis/qualcoms, as well as adb, fastboot) and see if there is something happening.
Report back if it helped.
Edit: Did you try different cables? had similar problems with op2 (not recognizing) with xiaomi cable...
Edit2: to make sure the device is completely dead, use a linux distro (e.g. Ubuntu, ensures that there are no driver problems, you can install it on a usb drive) and a cable which surely works (try it on at least 2 other phones, if data transfer works its ok) then first install fastboot (ctrl+t to open a terminal) by copy/pasting "sudo apt-get install android-tools-adb android-tools-fastboot". Afterwards hold vol- and power button for at least 12secs and plug mi4c in (release the buttons after plugging it in). Now you can run "sudo fastboot devices" and see if there is sth listed (should even recognize it in edl).

You don't need to use the modified cable as you can enter edl from fastboot, but the cable method is used to force the phone into it if you can't enter it the normal way. As for rescuing it, try the method @wertus33333 suggested.

Did it work?? Any information would be appreciated, so the next one with this problem doesn't have to open a new thread.... @colb16

Apologies for not updating, I got an answer on MIUI official forum from a very helpful member called Codex. Below are steps he asked me to follow and although it took a few attempts my phone came back to life after following below and then pressing power and volume down for numerous minutes.

phone wont reboot while usb cable is plugged in....

well this is a new one for me considering how many android devices i've had in the past. but a device that wont reboot once a usb cable is plugged in is rather new.
so i was flashing a bunch of roms ... some are N and some are marshmallow on my lenovo p1a42 ....
for some reason now if the usb cable is plugged into a pc or even a wall charger and i reboot it -- it just sits still at a black screen .... the moment i unplug the cable it continues to reboot.
one of the roms i flashed had magisk ... although i am not sure if thats the cause or not.
i need to be able to hold the volume up + plug the usb cable to restore stock firmware. i cant do that now because once the cable is plugged in it wont boot.
i tried different usb cables. same issue.
HELP!
((EDIT: Issue resolved. wiped internal storage + flash/cache/etc))

Question how do i reset when i cant reboot to stock recovery [solved]

so I relocked the bootloader after flashing stock and now I forgot my pin. I don't have usb debugging enabled and I can't reboot to recovery using buttons.

I need to reset but I can't

You should be able to reboot to Recovery. Just try doing it (holding vol up + power) with the USB cable plugged into PC.
