[Q] Phone reboots, galaxylogo, blackscreen! - Galaxy S II Q&A, Help & Troubleshooting

Long story short.
My phone rebooted when i plugged in my wallcharger (dunno if it has anything with that though), and shows the samsung bootlogo. But after that the screen goes black and nothing happends. Turns itself off again..
I was on MIUI 1.11.4 and KI4 Modem at the time. with latest CWM.
Couldnt get in recoverymode. downloadmode on the other hand is no problem.
So i then tried then to flash different stock roms with odin. still no go. Black screen..
So, anyone?
edit:
I've now got CWR working again. Tried to mount sdcard to pc but no go on this either. Will try to flash villain 1.1.. And if that doesn't work the next step will me repartitioning? :s booo

I have the exact same thing happen to me today!
The phone stops at the big flashing "S" boot screen. I waited a long time and it doesn't get anywhere. however, I then noticed, by tapping the the power button to put the phone to sleep, and then tapping the home button will bring me to the screen lock.
I can unlock the screen. But the phone home screen is black and the all shortcut keys including the four original shortcut keys at the bottom of the screen aren't there!! The only thing I can do are:
1. the dropdown from the notification bar. Everything from the dropdown work.
2. double tapping the home button will bring up the Voice Command
3. long press the home button will bring up task manager, and everything in that particular task manager page is functional.
4. volume keys are functional
5. power button is functional
That's all I can do to the phone.
Both the menu button and the return button are not working.
Can someone please help! Please advise what shall I do.
Thanks.

Remove the sd card, that should fix it.

If you can get to recovery might be a good idea to wipe everything and re-install from scratch.Wipe cache partion,dalvik cache,battery stats,format data,format system,factory reset and then reboot.Phone wont pass S2 logo so give it 2min,pull the battey,put it back in and boot to download and re-install your ROM (firmware first if you want aswell) then apps if you have a back up via titanium.

tried it. doesn't work.
My last resort would be to wipe everything but I wish I don't have to go to that.

Read from another thread, someone is having identical problem: stuck at the S2 logo boot screen.
He tried flashing several ROMs but without any luck: still stuck at S2 logo boot screen. No solution yet.
My condition might be slightly better as I manage to get to the home screen, only I can't launch any program since the screen is blank, and the MENU button doesn't bring up any menu as before.
Any other ideas? Please?
Thanks again.

Hey!
I got my problems sorted out after 4 hours of trying (and failing). Im not sure how to fix yours though but this is how i did it..
Eventually got the "Mount usb to pc"-function working in CWR (No luck with this function in win7, but worked as a charm 1. try in ubuntu). Transfered an old NANbackup i had and flashed that. No problems what so ever! Really odd since I tried to flash the exact same ROM from odin with no luck..Hope this may help you or others. good luck!

[Q] Alcatel OT-990 brick issue.

Hi there,
I wanted to install a custom ROM (Moonstone V1.1) on my Alcatel OT-990, so I followed the guides mentioned here to root and update my phone to be able to install custom ROMs. Everything went fine, so I proceeded to install the custom ROM. While installing I forgot to flash the custom ROM... and now I am caught in a boot loop.
I followed various guides mentioning all kinds of stuff to unbrick the phone posted here and on some other sites (some site mentioned formatting my SD card, tried that, nothing happened aswell).
I'd really be glad if someone would help me out.
take the battery out for a few seconds, press the down volume, home key and power, when the icon lights come on let go of the power key but continue to hold the volume and home key until the droid icon the let go of both, the plug the usb cable in to the top with the other end connected to computer and click start menu on computer and go to the recovery-clockwork-file that you should have installed, open the zip and run the "install.bat" you should be able to just double click on it , it will open up the "clockworkmod", just go into install from zip and flash the rom.. if you don't have the recovery-clockwork downloaded let me know and i'll get you the site to download it..... hope this helps....
---------- Post added at 08:53 PM ---------- Previous post was at 08:45 PM ----------
alot of phone are different so if you phone don't respond: plan B - hold volume up and press power, when phone vibrates, let go of power and press home key but don't let go of volume, phone should go into clockworkmod, if not then attach usb cord and follow the above direction from there.... good luck, its hard to brick the 990 without formatting everything and completely wiping all the files from sd and phone... and don't forget to wipe cache and dalvik and battery stats this helps... those can be found under advanced

Once you stuck in boot loop, can you flash stock rom via fastboot?

SG2 Logo, no boot, jig wont work, odin wont detect, after SG2 logo minimal flashing

I've really search everywhere for an answer and I hope somebody here can help me.
I had resurrection remix 2.5.1 on my phone and tried to update to 2.5.3. It installed but then when it rebooted, it got stuck on a boot loop.
My home button on my phone is not working so i used android sdk to reboot into recovery and restored my phone to a previous backup, I then downloaded 2.5.3 from my computer to phone and tried to reinstall and wipe cache etc, which worked, the rom installed, i rebooted and it worked.
Because I had just done a titanium back up before i tried to install 2.5.3 and i went back to a previous back up, i wanted to wipe the phone (because i had crap on it) and then reinstall some apps. When I did a wipe i did it through the phone, and when I booted back on, this is where the problem started.
My phone now turns on with the Galaxy S2 logo and then theres no boot animation, just a black screen which you can just about see that it is flashing. I tried to use android sdk to reboot into recovery but it wouldnt work. I didn't want the hassle so I brought a Jig, which doesn't do anything at all,l i've tried with the battery in and out memory card in and out and pressing buttoms. I thought it might have been entering download mode without the screen so I plugged it in and it isn't detected by odin BUT I have notice that sometimes the phone looks like its about to charge but when the battery icon comes up, the circle inside it does not move and then it disappears.
So to summarise, stuck on SG2 Boot logo, just notice blinking screen. My menu button is broken and jig doesn't work. Not detected by odin and wont boot through android sdk...
Sorry for the essay but I hope someone out there can help me!!!
No download mode, jig doesn't work, nothing with ADB = service centre. No other options.

One question though, will they be able to tell I've rooted it when I sent it to samsung and invalidate my warranty?
Hi mate, firstly can you confirm successfully flashed RR 2.5.3..?? RR came with its own Boot Logo and not SG2 Boot Logo.
USB Jig only works on older Bootloader...e.g Gingerbread 2.3.4.
VolumeDown + HomeButton + PowerButton still working for you..??

Well it says samsung galaxy s2 before then going onto a boot animation which was a stock android animation of the word android which I did think was odd
But now it just says samsung galaxy s2 without any boot animation.
And my menu button doesn't work... I guess i'll have to buy another one if its my last hope...

Try do a hard reset but holding the left "soft" key when powering up the phone.
---------- Post added at 09:34 AM ---------- Previous post was at 09:30 AM ----------
Not sure if this will work but try a master reset as well.
To do a master reset do this:
1) Turn phone off
2) Hold the two soft keys and power back on
3) As oon as it states 'hit ok', hit ok and then allow the phone to run through the reset...

[Q] LG G3 stuck in miniOS 3.1 + unresponsive screen

Alright, so i've searched and searched but i can only seem to find my problems separately. It started with the replacement of my new screen. i got it off Amazon and worked fine at first. but then i began to notice that once i locked my phone, the touchscreen would deem unresponsive( a battery pull would temporarily fix the issue) . i tried to fix the issue by going into the hidden menu to hopefully re calibrate my screen but once i tapped device test, i got stuck in the miniOS 3.1 and the worst part is that my touch screen wont respond( even after battery pull). so i cannot physically touch "OK" to begin the "Auto Touch Test"
Does it give you factory reset status 2???
no, i cant go any further from the device test
Do you see power off or restart button if yes press and hold power button while holding tap the power off or restart on the screen.
my touchscreen is unresponsive. i cant tap anything. is there any button combination or a computer program that can help?

Hey, does anyone know if there was a fix to this problem? I'm having the exact same issue and Power + tapping Normal Boot doesn't work since my touch screen is having problems. I'll still be looking around in the meantime, thanks!
Plug in your computer and pray for fastboot commands or adb, examples:
adb devices (run in thermial)
adb reboot recovery
Or
fastboot devices
fastboot reboot
Then hardware keys to custom recovery
If all else fails call customer service and try to get a replacement. There is no way (that I know of) for the device to look "flagged'. Pretty much we don't get any red bootloader text.

Phone keeps restarting only can enter download mode

First of all sorry for my poor english
So for no reason my Samsung galaxy s6 edge turned off and now it keeps doing same thing over and over again till battery dies. Phone keeps restarting every 1 second till battery dries out completely once connected to charger it instantly turns on and keeps restarting no matter what. The only thing that works is download mode, but after succesfully flashing rom it restarts and keeps doing same thing again till battery dies .
Also tried flashing custom recovery still can't enter it using button combo
Model:SM-G925F
Update: Now it keeps rebooting as always but white indicator led keeps flashing.
1: Remove sim card.
2: while it shows samsung logo instantly press volume up and home button.
3: if its not entering recovery then keep holding power and volume down button.
4: Let it flash the logo few times
5: then try to enter recovery and wipe data factory reset.
i was having same issue and i fixed this by removing sim card, do not insert sim card until its completely ok

Didn't worked . Also maybe there's something with phone's hardware :? since it doesn't show battery icon once i plug in charger it just instantly goes to restarting.

As i said i can only enter download nothing else tried to enter recovery like 100 times
what is your firmware version and build number, try to reinstall same firmware it was on the device before.
there is some thing wrong with your boot.img , it can not find system.
anyway try to reinstall through odin and plug a chrager that must have at least providing 2 AMPS of current at 5 Volts.
---------- Post added at 03:36 PM ---------- Previous post was at 03:32 PM ----------
some times its week battery problem and while booting processor needs enough current to start.
so if the battery is week it can not provide enough current while starting.
i have fixed this issue with many devices with bad battery circuit which is built inside the battery not in the device.
---------- Post added at 03:39 PM ---------- Previous post was at 03:36 PM ----------
3rd
try to install your rom with pit file and select "nand erase all" in the odin.
good luck
