[Q] Help with a bricked phone!

Hi guys,
I decided to flash a kernel, Team Skyfire kernel in fact, on my Samsung Galaxy S2 i900.
Problem is, my device is now bricked. I can power it on, it shows the samsung logo along with the root triangle, then shows the new kernel boot logo, then the screen turns black. I think it powers off, but im not sure. Sometimes if i press the home button the screen will then turn white.
I had CM10 running beforehand..
Can someone please give me advise on how to solve this?

Well firstly your phone is NOT "bricked". All you have done is flash a incompatible rom/kernel combination resulting in system partition not booting. This does not mean your device is bricked of "soft-bricked" as some n00bs like to call it now.
Its likely that the kernel doesn't support Android 4.2 (CM10.1). Just reboot device back into recovery or download mode and flash a compatible kernel to get your rom booting again like the vsync patched Siyah or other.
Alternatively re-flash CM10.1 and it will replace kernel with cm10.1 default.

Touch Screen works but no display or colors just black screen

I have a xperia u After replacing the housing touch doesn't seem to work.... Device turns on device leds blinks but screen is just black lighted without colors.... after booting up (after 2 vibrates thats how XU boots) when i press camera button it opens the camera (flash light turns on) when i touch where camera icon is it just captures the picture(flashes and i can hear the capture sound)
Simply the problem is touch works. its responsive but no colors it just lights up thats it. Digitizer works to (menu, home, back buttons) cuz after booting up when i touch it it vibrates.
(When i keep removing the battery and restarting a single time sony logo came and went)
Please someone help me to solve this issue.....
my xt890 lcd screen and digitizer were broken so i changed them and the phone was working fine for a week, i then wanted to update to kitkat through oem update; everytime i tried it would give me error . i then read that since i unlocked bootloader and rooted my phone and installed cwm recovery i couldnt do an oem update and i had to do a factory reset in order to update through oem, so i did just that ; after the phone finished factory reset and booted i proceeded with oem update while the phone was charging, everything was going fine the file was downloading, i went to the bathroom and came back the display was black, but touch screen was working fine...through more searching i read that this could be from the update, and i should do another reset... since i couldnt see anything even recovery menu. i downloaded moborobo so i can see my screen on pc and proceeded to factory reset ... now i cant even see through moborobo and im stuck. Please help.

[Q] Need help unbricking a z787

hello everyone
this phone is NOWHERE... i cant believe how few people have this phone in the hacking community.
I've used a guide seen here
https://www.youtube.com/watch?v=BCiq21WsFEc
essentially I rooted it in KK successfully. Then I installed TWRP through the twrp app... installed successfully. no error.
Went to reboot, phone does not get past splash. Recovery instantly goes to black (powered off) screen with red LED (tells me the phone is kind of on.. but some serious hardware misunderstanding taking place.)
How can I restore the stock recovery? While it is in this no-display-red-light mode it appears on my computer in DFU... so I know it is possible to still get in there, but I cannot find anything about the stock recovery for this phone.
Can't believe ZTE has little to no support for this phone...
Possible solution
That video seemed to be for the newer model of the zte grand x, thats why its called grand x plus. I had tried it on my phone and it was like stuck in a power up loop, what i did to get out of it is to go into recovery mode by pressing and hold the power button plus the up volume button. One i got in there i just rebooted it. Try that out and see if it works. Im still looking around for a solid root for this phone

HTC One M8 unlocked International Version on Reboot Loop

Hi There.
I Have an HTC One M8 International Version has not been rooted just plain custom stock installed, it was working Fine, all of a sudden it went off and wasn´t able to be turned on, at this point it would just vibrates repeatedly and was flashing led indicator on green or orange (times blinking/at times solid).
I read on some other forums it might be a battery problem, so i swichted the battery with no results, kept doing the same thing. as getting deep into this some other peeps suggested it might be the screen so i changed the display.
Now, with the new battery and a new display i manage to get the screen to work but i just keeps rebboting (on htc logo) after 10 secs even if i power it off it will turn on and keeps rebooting, im able to get to hboot menu but no furthermore, wont go to recovery at all, and will restart boot loop when chose any option (fast boot, reboot or recovery).
Help please since it is not root, quite sure it hasnt been erased the rom.
:crying::crying::crying::crying:
Any help or suggestion to get it to work again, just as a factory device.

Black screen after Logo[GFive President G9]

Hello guys, I have run into a serious problem here! Please help me out..
I have a GFive President G9 Android running stock Jelly Bean 4.2.1 (ROOTED). I tried to install a boot animation through ROM Toolbox app, when I rebooted it, it didnt show any boot animation and booted straight to the home screen. So I just went into the ROM ToolBox app and restored the bootanimation backup I had created earlier to get the original GFive boot animation back.
However, when I rebooted, my phone showed the GFive Logo, and after it the screen went dark( The screen is backlit but doesnt display anything). It just stops there and doesnt do anything. Ive tried removing the battery but to no avail. For some reason I CAN'T ACCESS the RECOVERY or the DOWNLOAD MODE, as holding the power button and vol up etc still ends up in the same situation - Black backlit screen after logo. The phone isnt in a reboot loop or anything, it just stops at the black screen for eternity.
THE WORST PART, this phone probably has a damaged USB port, since I was previously able to charge it via the PC, but it wasnt detected in the PC. So I CANNOT CONNECT IT TO THE PC.
So is there anyway I could get this phone back alive? Is a factory reset possible? Please help me experts!! :crying:
P.S Custom TWRP is installed, but I cant access it
So there's no expert in this whole forum who has a solution for this? Because no reply means no one has an answer..
Incase theres no way out of this, please mention that.
