lcd-backlight-ctrl start determine-lcd-type,lcd type:61bc11

My Samsung Galaxy Mini won't turn on, when I press the start up button a message comes up on the screen i.e.( lcd-backlight-ctrl start
determine-lcd-type,lcd type:61bc11) but nothing else happens. When I press Vol down+Home+Power, phone boot on with a lot of texts,
and start normally. I can't get recovery mode or downloading mode for odin use. Can anyone help me please? I'm newbie. Thanx

Same problem right here. Any idea?

What have you done before facing this issue?
Sent from my GT-S5570 using xda premium

In my case, volum up button doesn't work, and phone doesn't enter in downlaod model, just in some emergency mode arm9... something like that. I try to update software, i think because it's some software problem. After that, everything ok (start downlaod mode with kies, and update with odin). Odin show pass(isn't first phone that I update with odin, but everything before was ok). When phone start, show this .... and i don't know what should I do. Any help, any idea?

Downlaod mode doesn't work. Enter in : "emergency dload arm9..." something like that.

Be careful and press only vol down and not both volup and down...try.

Before, I update with odin: Galaxy S, Galaxy gio(2x), Galaxy ace(3x), another galaxy mini, with odin.

Weird it is then, cuz i know holding volup+down+home+power will get u to emergency download mode...whatever that is.

It's possible.The person who gave it to me to make them update said the volume up button does not work very well. Be a reason? Phone also have another problem, battery drain, in 5 minutes, battery goes from 70% to 20%. Wipe battery stats in CWM should resolve this? 100% probably no, but something?

Im having the same problem, I get "lcd_backlight_ctrl start" when im trying to turn my phone on, can only go to Emergency download mode
I have firmware from http://forum.xda-developers.com/showthread.php?t=1551586 and i get this error after i tryed to go to recovery mode (Clockwork recovery not flashed)
EDIT: Got into normal download mode, reflashed roms, now its working fine. Apperiantly theres a problem with my "Volume up" button.

For future
This combination which u have triggered is: Volume up + menu + power or just Volume Up + power

it's so easy bro.
you just have to put off your battery from your phone and then put it in to the phone, finally you have to press vol down+power button until the phone logo is shown up

Have you tried the right combo mate? Download mode: volume down+home+power
For selecting in recovery mode you can do it with the power button.

yes I know how to go to download mode via the 3 buttons , this is not my first time using Samsung mobiles and they all the same
and also not my first time doing root and changing rooms
but this is the first time I face this problem and only in this galaxy s 3 mini (I've rooted another galaxy s 3 mini before and there was no problem with booting into download mode)
also I know that the power button is for selection (I already mentioned that in my post )
but it doesn't give any respond (only in recovery mode) while there is no problem with the power button if I used it with any other place in the system

Well Mr. Mad-Ungrateful-Expert... maybe you can try buying other phone.

Try this :
makeyourself said:
Your problem sounds similar to this one. I assume when you say 'blank screen' that the screen is powered on?
Power off the phone, hold down VolUp + VolDown + Power for 4 to 5 seconds. Then release ALL AT THE SAME TIME. Now press Volume Up. Now hopefully you will be in download mode even if you can't see that you are. If it doesn't work try it again a couple of times. The reason that you have to press Volume Up is that a warning screen is actually displayed before the phone lets you into download mode.
The phone will give you no other indication that its in download mode and won't 'recognise Odin' when not in download mode. Make sure you have Samsung USB drivers (comes with Samsung Kies) installed on your PC.
Oh yeah and by the way the thread I've linked to suggests you have to reflash the bootloader to fix the 'blank screen' problem.

I've already asked him what did he do with the phone but he didn't respond to my email yet

Have you tried installing the latest firmware for your device with ODIN? Maybe that works.

[Q] - HTC One (M7), Stuck in Bootloader.

Hi all,
Apologies if I don't include all the information you require, first time posting in here. (I'll add some screenshots tomorrow evening)
I was attempting to unlock the boot loader to begin the process of installing Cyanogen Mod onto the device. After powering down and entering the bootloader(?) I have been unable to select any options and can't get out of it. It appears that the volume up button works, but the volume down and power buttons do not. The device isn't recognised when attached to a PC either. Not really sure where to proceed from here and any help would be appreciated.
Cheers,
Gurk

Hold the power button to reboot the phone in the OS. Then get your volume button repaired, you'll need it if you start flashing stuff, even unlocking the bootloader will requires to use the volume down button.

Holding the power button does not reboot the phone into the OS. The volume buttons do work as does the power button, however in the bootloader only the volume up button appears to work. (Sorry that I did not make that clear in the original post)

Huawei Ascend P7 - bootloop singular problem :(

Hello, my Huawei P7 during automatic update does not start up again. I can't go into download mode or fastboot . I have tried all ways , with the attached USB cable , pressing pwr + vol up, vol down + pwr , pwr + vol up and down . Always returns to the same place: Software install failed!
I managed to use this instruction (http://www.carbontesla.com/2015/07/guide-restore-ascend-p7-b805-lollipop-to-b609-kitkat-firmware/) to do downgrade using the transition pack , then downgrade to the B609 and unlock bootloader according to the instructions (http://forum.xda-developers.com/ascend-p7/general/unlock-bootloader-huawei-ascend-p7-l10-t2830641)
Everything I've done via SD card by force update

Have you thought of taking it to the repair shop? Because I'm thinking that this might be more than just a software problem.

your initial issue was that you DIDINT format data when you first flashed twrp. please read dr.ketans guide in the guides and discussion thread.
when the phone reboots by holding vold down and power, very very quickly swap to the DL button combo(vol down + bixby) and plug cable. reflash twrp 3.2.0.0 and follow the instructions. ( when odin fisnishes flashing twrp in the AP slot, DONT let phone boot to home screen or at all. immediately hold vol up +bixby +pwr to enter twrp recovery. then swipe to allow modification and go directly to wipe menu and format data. type yes when asked. go to reboot menu and choose reboot to recovery and flash

jd14771 said:
follow these steps, you must be fast and diligent with the button combinations:
-first, plug phone into computer
-Second, HOLD POWER + VOLUME DOWN until device restarts, as SOON as the screen goes black you must let go of all buttons and immediately hold VOLUME DOWN + BIXBY
-you should be in download mode.
the phone has to be OFF and plugged into a computer BEFORE you hold VOLUME DOWN + BiXBY in order to enter download mode. You can not trigger this while the phone is on.
