[Help] Phone goes to Download mode with Black Screen - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hi,
I've kinda weird problem with my skyrocket.
When phone boots, just split second of boot screen appears and then total black until boot complete and i have to press unlock button twice to wake device. And after that while using, whenever i start browser or camera app, it goes to black again.
then i decided to flash phone again to ATT original 4.1.2 firmware wia ODIN and found another problem,
In download mode, screen remains totally black, phone detects by Odin but nothing on screen.
then I've tried flashing 2.3.6, ICS and JB original and CM firmwares but no success.
if anybody aware about this issue, please help.
thanks. :good:

It's not a hardware issue though its a complete brick I just want to make sure other infuse owners don't get the same mistake and what steps can be taken to prevent it I am a noob when it comes to flashing especially this being my first samsung android but its the red cwm to the blue
it's not a brick.
brick is when you get nothing. absolutely nothing.
you've some sort of power looping...not brick.

[Completed] [Q] i9100g recovery mode missing and download mode has an android with a 0 in it.

Hi
i recently bricked my phone while updating from stock to phils cwm recovery and my cable unplugged. After that my phone went just dead. I read on the internet and used a OMAP flash and after that i could access my download mode, but it has a yellow exclamation mark triangle and has the android mascot with a 0 in it. I dont know what that means.
Now i some how managed to put a stock rom in it (Gingerbread). But it never switches on. I keep getting a blank screen, not even the samsung bot load symbol comes up. But when ever i use a pit file to just repartition the device my phone starts up and the gingerbread os switches on. But it keeps flashing that every process of google is being forced close, so i cant even move ahead. its just stuck there, and error keeps coming up with force close pop up.
If i try to restart the device it gets the blank screen again. it works again if i repartition it.
i even tried nand flash, but it gets stuck in odin after the message Erase.....
i tried adding a new recovery to no avail. Neither does a new Android OS gets pushed in, gets stuck at NAND write start.
The phone doesnt let me access recovery also. It gets the same blank screen when i try.
help please

Hmm ... after flashing a custom (PhilZ-cwm) recovery, the yellow triangle shows that you are no longer on official/stock firmware.
You can reset it with TriangleAway app from Chainfire.
If download mode still works, you can try to flash another (custom) kernel with a custom recovery. But it has to be a kernel which is compatible with your current ROM.
For further questions, please post in the Galaxy SII GT-I9100 G Q&A thread.
If you have issues with your download mode, check the [GUIDE] Fix an unflashable or soft bricked I9100G thread.
Thread closed ... thank you !

Help required S7 DUOS [SM-G930FD] hanging during update after flashing stock ROM.

I have been given an S7 SM-930FD [Dual Sim] that was supposed to be bricked. It wouldn't boot into anything but I have successfully got it into download mode and been able to successfully flash a stock ROM downloaded from Sammobile [several times] with no errors. Each time I have used the full set of AP,CP,CSC files and the previous owner is not sure what ROM it was on or what he tried to install. I have tried different versions of the firmware for this model for various android versions and regions simply to try and get it to boot, but without success. I have tried HOME CSC and CSC files too.
But each time it starts to install the update / reboot it hangs. Either when it installing the update on the blue screen with the robot and its "erasing" - small rotating symbol just stops and nothing happens OR it loads to the GALAXY S7 normal boot screen then hangs.
When it hangs it will only respond to one key combination Power + Vol Down. It then "switched off" and will not reboot in any mode. When I say "switched off" I mean the screen goes black. However if I then connect the charger, it won't show the charging symbol UNLESS I leave it for a few hours and the battery goes flat. It will then charge and I can boot into download / recovery mode but normal boot starts installing the update and it will hang all over again. On one occasion it hung with and black screen and blue flashing light but again no key combinations worked and I had to wait for the battery to drain.
Also tried Smart Switch Emergency Recovery. Even with the drivers freshly installed it does not recognise the phone, it does accept the model number during initialisation, but once the S/N is entered it comes back and says it can't find the model, S/N or IMEI in the database!
I have researched the web for hours and watched every relevant youtube video and tried their suggested key combinations etc and they just don't work.
So I'm hoping someone can help me resolve this frustrating situation, not least because of the delays between attempts!
Presumably as I can consistently get it into download mode there is a solution out there somewhere???????
What am I doing wrong? Should I be looking at a custom ROM or trying something else?
All help appreciated.

Problem with bricked GT-N8000

Hi everyone
I have GT-N8000 2012 version. A week ago it suddenly went off and I am no longer able to turn it on, i.e. after showing the Samsung white logo, it is restarted. I have tried flashing different firmware versions but it doesn't help. Also the Power+VolumUp combination does not show any menu (I think it usually boots a menu for factory reset). What can I do? (I prefer being able to recover my data).
Thanks in advance
Same problem here, on same device type (N8000 2012, standard stock samsung firmware).
Mine doens't even reach the Samsung logo. It just gets to the 1st screen (Galaxy Note 10.1 white message) and reboots after a couple of seconds.
Also can get to any menu using Power & VolumeUp (doesn't seen to have any effect). Only Power &VolumDown gets to the Download menu.
Unless this is a Hardware problem I wanted to factory reset the device, hopping this would clean "everything" but put it running again.
Thanks
Suggest flash stock rom via Odin ,and download mode.
try this one

no worries. it happens. soft brick situation
you need a stock rom for your device or back up rom.
go back to PC and start ODIN, cable in, then boot your device under download mode not recovery.
once it is in download mode, flash your device using ODIN.
allow to reboot.
un-bricked device.:good:
stock ROMs are here in case you are looking
