how exectly?
i can't reach recovery i cant reach download mode
all the phone is doing is boot loop

Of course you can. i think that you should shutdown the device and just hold the three buttons, it should work if you on bootloop

a bit of a problam
when i press the power button nothing happen, the only why to shutdown is let the battery drain
from the bootlooping but in the moment I plug the phone to charge so I can do something he is bootlooping

I think you can get the battery out of the device and put it in. im not sure so you should check it. i think that this is the thing i did..

Pull the battery. Put it back in. Hold power button and volume down until you're in download mode.

Well that's deffinately weird.
Is it under warrenty? Because if you can't get to download mode I'm thinking that's a next step.
How about recovery? Can you get to recovery? Power plus volume up?

if I could get in to recovery , this thread was not exist because in "basic" bootloops
I know how to fix.
warrenty it's a bit of a problam because my phone is rooted and rooted phones disable the warrenty
but it's dont boot up so how can know he is rooted LOL, I think I'll go to the store i bought it from
and ask to fix this, but I prefer to fix it in my home so if threre is a solution I'll take it

Apparently I forgot to add the line to put it back in, Wow D: Atleast theres clarification ,Thanks for that. Will add it
@tanmay, Dark grey? That means the phone isnt completely powered off, Theres still backlight, Has to be completely powered down, I do hope its done in download mode. Anything flash related is purely in download mode to assure 100% safeness
but it doest help(((.it seems it is turning on but no download mode image.is it normal?
we know that we have to put it back....but the screen lightens up to dark grey and no download mode.what to do?

Check and see if you can enter recovery mode or if its broken. Vol Up + Home , Then 1 sec gap, Hold power till it vibrates, Make sure theres no backlight or thats not completely shut down.
@rit, Well yeah :\ Cause you know, Phone without a battery and hoping it will turn on--Just no comment there rofl
could you go into download mode?my screen is still lightened gray

yup..it was totally over...i earlier flashed into xxkb3..it was no problem then...dunno what happened now...SAD
plus i have my usb cable removed
Mines works perfectly o.o Flashed mine before making the guide. Hence the guide.
1. Take out the battery. 10 secs just to be safe. There should be no light. Or phones still alive.
2. Yes the 3 button combo is annoying, But its the only options android has given us. Recovery mode can break but it can be restored. Download mode is your highest prior. I dont know if your battery is low. If it is then use a direct power supply, phone will turn on without a battery. See how far it gets to turning on.
3. Replace the battery and retry the same, the pit file shouldnt harm the phone in any way.
4. See if you can enter Download mode.
Also i hope you flashed it when it was in download mode. The android digging picture should have been there when you flashed the pit or any other file. If you flashed it on a black screen *happens when adb server keeps the com port alive* it bricks the phone.
if there appeared pass on the odin, it means yes.yeah?

yes you can remove the usb............may i suggest taking off the battery for a while.........go for a walk , catch your breath and come back maybe it will work then!
Yeah, That means it worked. The pit file is just to prepare the phone.
See if this helps you in anyway

Well, I suggest you to try VillainROM 2.1. You will have to flash cf-root (the version of it has to be the same as the version of your current f/w), connect your phone to pc and get the VR 2.1 into your sd card then power off your phone, volume up + power + home button - do a full wipe - choose to install a zip from sd, flash villain and you will be fine..hope so. If you get stuck @ any point, you can scream for help cuz I will be here to support you mate
Forgot to get you this: http://forum.xda-developers.com/showthread.php?t=1103399 It might help you though.

Try to enter download mode (volume down + power button + home button) and flash with odin a stock rom.
The main problem now is I can power on my GSII so I can't enter any download mode and recovery mode.
I don't know how to do now and please help me, thank you.
Just power off your phone. If doesn't work by the power button, pull out the battery. When the phone is powered off, press the 3 buttons same time and you will enter download mod.
Sorry for my typo mistake, now I can't power on my GS2 so I don't know how to enter to download mode

You dont have to power on your device to enter download mode. Just push VOLUME DOWN BUTTON, POWER BUTTON and HOME BUTTON in the same time. Then, push volume down to enter odin mode. After that, connect your cable to your device and press start in odin (before that, dont forget to put the stock f/w into PDA in Odin)
My GSII still no response and I think the row is dead and can't bootup so how can I do? Tks brother
So after your flashing width odin did odin say pass or complete?
You may still be able to get into download mode but just not see it,
When you hold the key combination then plug it into odin and see if it comes
Up with the yellow box that tells your if your device is connected.
edit : so you hold power, volume down and home then you have to press up to enter download mode, after this plug it in to odin and see if you can see the phone.
There is no response after boot my phone and it hasn't say pass or complete.
Then the phone can't open again and I don't know how to do now, please help.

Why cant you enter the downloade mode / recovery? All you have to do is hold volume up or down with the home button when you put the battery in. You don't need to press the power button then.

[Q] Can someone help with the solution?

Hey guys,my phone will automatically turn itself on when i insert my battery. Then after the Samsung logo, the screen automatically turns black. I first suspected that it was a battery problem, but that did not turn out to be the case. I think it has something to do with the power button. I also tried to boot it up into recovery mode but the screen still went black before i had the chance to do anything. Any help would be appreciated. Thanks

A1 Suddenly Dead

Hi
i bought before 2 weeks Xiaomi a1
it wored very good.
Today while I wanted to turn on the screen it did not respond.
The phone is not responding to any type of pressing.
I must say that the phone is new, did not get any kind of hit , and 5 min before this problem it used to work really good.
I think that the phone is in brick mode, and i can't enter to fastboot option because the phone is not responding....
Pls help my solve this problem.
Thanks
Try holding the pwoer button for more then 10 seconds, that should reset it... once you start it up aghain turn of ambient screen... Gave me troubles too... Hope that helps.
Has that still not been fixed with November update? I turned my ambient screen back on to see. So far, 2 days since update and no black screen after notification.
I'm guessing it's not dead. I have the same problem before as well. It was the buggy Ambient Display. Force restart your phone by pressing power button and holding it more than 10 second. First thing on boot up complete, go to Settings > Display and turn off Ambient Display.

Leave the phone discharge
Then let it charge
Then power on with vol down + power
Try these 2 things
1) charge your phone for 2-3 hours. if didnt switch on try this 2
2) Connect your data cable with pc. In mobile Press volume up + volume down and plug in the other end of usb cable to your mobile. you need to hold the keys. this will boot your phone into fastboot.
If boot steps didnt work then it might be a hardware problem or hard brick.

Visit customer care(they will probably say motherboard problem as always) or try qfil method which is quite complex if this flashing things are new to you.

you should press the power key while charging cable connected.If it doesn't work , unplug the charging usb and plug again reverse(type c's reversibility).If it can't, try with another AC source,another person,another location.

You switched off the phone in middle of installing ota, best bet is take it to the take it to the service center and tell them phone not switching back on after installing August ota update.
Or if not in warranty then try to install stock rom using qfil.
Unfortunately you have bricked your Mi A1

You have bricked your Mi A1, when you turned it off while installing/flashing the August update. Basically you should never turn a smartphone off, or disconnect the USB cable (if it is connected), while flashing its ROM.
There are various methods to unbrick it, I suggest you try this one since it's apparently not going into fast boot:
