Hi everyone. I apologize for my poor English.
I rooted my Archos Cobalt and everything worked perfectly.
Several weeks of use without any problems.
After installing ToolBox ROM and change Boot Logo Animation, a few days later, my tablet would not start easily but I could start with the ignition button and volume up.
At present, it is impossible to start it. Still a black screen. NOTHING! :crying:
I followed different methods to get my Archos Cobalt unbriked but it does react to any of them.
Any of you know where can be my problem?
Thank you in advance lean on my worries.
Good day / evening all

Hi and thank you for your reply.
I can not access the recovery menu or something. My tablet does not turn on. Exactly as if the battery was discharged.
I do not know if it is on or not because the screen is always black no matter manipulation I can do (Power Button + Volum up / down, USB cable or not etc ...)
Nobody has an idea?

Hi guys!
I have a big problem with my Galaxy Tab 10.1.
Everything was fine, before I launched a game (Angry Birds), and then my Tab was freezed and now I can't do anything with it. I only can see a black screen, with the notification bar, at the bottom, but it doesn't make anything when I touch it. I can't turn off, and I can't take out its battery (why...). What can I do? I tried to plug it to the charger, but nothing has changed.
Stock ROM.
Thanks in advance!
Did you try holding the power button for a long time. like 30 seconds?

I installed Indirect's method to gain root access and now the N button on my tablet won't work. I tried to post on the development board but since this is my first post it wouldn't let me. Any insight into how to get it to work or why it stopped working?
Because of home catcher, fix: 8 failed reboots

What I mean is how exactly do you get 8 consecutive failed reboots?

when your NT boots up there will be a black screen with the n logo. right after that black screen disappears, hold the power and n button at the same time until the NT shuts off. repeat 8-10 times and you will be greeted with a factory software reset screen.
at that point, the NT will be booting into it's own recovery software. once that process is complete, you will be starting off with a fresh NT, assuming your original software was 1.4.0, otherwise it will be 1.4.1
hope this helps!
Do a factory reset. I had the same problem - N button stopped working. Password protection stopped working also. Only help was a factory reset. At the time, I didn't have home catcher installed - still don't.

Let me think about this... N button doesn't work... Hmmm, hold down the N button... but, the N...
If the n button has failed in that regard, no amount of resets will repair it. That's a hardware failure and you would need to return the unit.
Try it. The n button may just not be working as expected from software.

Okay I need some help to fix my phone because somehow I did something to my phone it really did not like. I will try to keep it as short as possible.
Since last week I was running liquidsmooth nightly LS-KK-v3.2-2014-10-13-umts_spyder on my xt910 and it was running as smooth as it could get.
This morning I decided to simply reboot the phone for no particular reason, battery above 90%, it shut off, it turned back on, showed the motorola logo and then a black screen. nothing else and I have not been able to make it show anything else.
volume+, volume- and power button in every combination, result in the same situation.
on the black screen I can press volume keys to make it vibrate but I am not sure what it actually does.
windows recognizes the device as motorola usb composite device and an MTP XT910, so far so good. Even RSD lite shows it as xt910 and connected though all device properties (IMEI etc.) are N / A and flashing results in "phone could not change to fastboot mode"
I found a similar problem described here: http://forum.xda-developers.com/showthread.php?t=1767469 (especially the last post).
Since the last reboot I installed plants vs zombies 2 and reinstalled google chrome, nothing else has changed.
I can't get into the fastboot menu to select ap fastboot, I tried doing the right steps at the black screen blindly but apparently it is not the same screen.
I am pretty clueless what to try next and I am not even sure if the phone is still being charged when I connect it to the charger.
sooo what to do?
thx a lot

You have a black screen but the phone isn't really turned off...
When you see that black screen,press and hold the power button until you see the white line flashing for a moment,like on Tv,that means it's turned off.
Immediately after that press all 3 buttons,vol-,vol+ and power button to get into the boot menu and then choose AP Fastboot from there.

interesting, first turning it off by holding power allowed the three-button combo to bring up the fastboot menu. thanks a thousand times.currently flashing sbf image
:highfive: worked

just a quick thought, is it possible that I provoked the black screen by using liquidsmooth on the system1 slot?
Not likely. Liquid Smooth has been in my #1 slot for quite a while. (Not stock side, just 1st slot on safestrap....)

hey guys : )
im quite a beginner considering anything about configurating my smartphone... Yesterday i did watch a video with the youtube app and then my display suddenly froze and became black. Since then everytime I push the power button the screens keeps black but you can notice that its getting a little bit brighter. So it's basicly still active but I dont know how to fix the problem. the only thing I tried so far is to reboot (10s power button + volume up) but it didnt change anything. When i plug it onto my pc it gets recognized instantly.
Could anyone of you tell me how to fix my problem?
greetings
Hi folks,
i got a LG L3 II E430 and rooted it. It worked great for some days, but now it just turned off and wont turn on again. When i replace the battery and start, the home button lights in different colours, after a while it stops, the screen is on but black, the menu and back button react but there is no sign of a function.
When i hard reset it (battery out, then starting with home and Vol- button pressed), the same happens. After some times, the screen had a few thin vertical stripes and you could JUST guess that the LG-symbol is there when starting.
Before all that, i just hat titanium backup save Data and apps and installed Xposed framework and xprivacy. I had both (xposed and xprivacy) installed a couple of days before all that and had no problem.
Does anyone know what happend or even better has an idea what i could do to save the phone?
thanks in advance,
Simon
EDIT: After a couple of tries, the hard reset worked!
Hi again,
after i managed to hard reset the phone, i did not reinstall Xprivacy or Greenify. It worked for 3 days, but now the screen turned black again. Sometimes there were some very thin vertical lines in some places.
It seemed to work, because the menu and back button lighted up when i touched them. also i could shut down the phone when staying on the power on button for a long time.
After 3 restarts, this time the phone managed to wakeup again, just as normal.
Does anybody know what the problem might be, or if there is a way to check a failure log or something like that? To me, it looks like a hardware problem. In that case, i could send it back since i bought it a week ago..
I got Kingroot and Titanium Backup Pro installed, if that helps.
Thanks a lot, Simon
