I already know what caused it. It was caused the dual speaker mod.

Ah thats not good,i suppose you dont have a Nandroid either? i suggest you do a nandroid backup right now, format data & cache and try rebooting. If it still doesnt work , your /System partition may be corrupt. best to go with the above mentioned post by klebengan which would return you back to stock.
Mind you, in both cases you would lose your data. so do a nandroid right now, atleast wou would have a chance to extract important data later once you are up and running again.
BTW, This is the wrong place for this thread, it should be in Q & A and i m pretty sure there would be similar or related posts

ok, thanks for the tip but I tried to even follow the Klebengan post but the main problem is that I am not even able to go to the download mode with the volume key up and Plugin in the usb cable.
I have the flash tool and the kdz file but as i said I am not able to go to the download mode so I am not able to use the LG flash tool also.
If somebody can help me with the steps of transfering the zip file in to the phone memory I can atleast try to install the custom rom once the phone goes on and starts than I may try to flash with the kdz file.
pls help

[Q] Phone Won't Reboot Without Looping.

I got my new Note 3 2 weeks ago and after a week of ownership decided to root it and install a custom rom.
Rooting went fine and then I installed my first custom rom Echoe Rom v.4.1 Full. But the problem I had was that, after installing all my apps, when I went to reboot the phone it just went into a continuous bootloop. So I thought I'd try another rom and installed Omega v4.0 and had the same problem, boot loop after rebooting.
So my question is why? Why are all roms causing me bootloops after I reboot? I'm having to either keep charging the phone and keeping it on 24/7 or if, for some reason it does power off, clearing davik cache and performing a factory reset to enable me to boot the phone up again and go through the whole install process over again.
Can I do anything to stop this or has anyone any idea why it is happening please?

Thanks but I've tried that and am still getting bootloops on all roms I install! I'm now trying [26.11.2013] X-NOTE v5.1 N9005 MJ7 and yet again, after going through the initial setup and installing my apps, I'm getting bootloop when rebooting the phone.

Check this ROM it fixes all my issues,Wipe/Factory reset from recovery mod then flash the first PreRooted rom via Odin 3.04 in the thread and make sure you unroot your device.

Many thanks Dahdoul. I'm downloading the first PreRooted rom from the thread. Hope that's the right one! Do I need to unroot the phone before powering it up and, if so, how do I unroot it?

two ways to Unroot your device:
Go to superuser app in your phone then settings press on unroot completely option and you are ready to go.
OR
In recovery mod Wipe cache partitions and reset factory settings then flash the stock rom by odin.

Soft brick oder Hardwarefehler? Bunte Muster

Hello,
I have a broken Galaxy S4 GT-I9505. After the last update went wrong it falls into bootloop. (it stucks at the Galaxy S4 Screen). After a while you can see the screen showing some grey patterns or lines in RGB colour. After flashing the newest firmware over Odin it just starts into recovery mode after putting out the battery for some minutes. After wiping cache and partitions it starts with sound but stucks at the pulsing samsung logo. After a while it reboots and it starts again. I really dont know what to do... Is it a hardware error maybe? After entering the recovery menu you can see CSC VIA. This happens after flashing a DBT Firmware too.
Can you go into Download mode?

Follow this guide: http://www.android.gs/manually-upda...5-lte-to-android-5-0-1-i9505xxuhoa7-lollipop/
Okay i will try this fw with 4 pieces. I tested just 1pcs fw`s...
I let you know if it worked for me...
The same reaction as mentioned before. After flashing, the phone restarts, stuck at the first Screen and falls back into bootloop after a few seconds.

That happens shortly before reboot.

I think the only way to fix that is zu flash a custom recovery like twrp and flash a new Rom
okay i installed TWRP on the s4. Everytime i start the backup funktion the screen becomes pink or any other possible colour... I think the CPU is the broken part? Would it be enough to replace the mainboard?

Try only to backup data and wipe the system or wipe all partitions. But im not sure if it helps good luck
I think its broken
It doesn't matter what i backup... shortly after the start it crashs....

When backup doesn't work there is only one way. Wipe system/data/cache/dalvik/ (optional internal sd) and install a custom rom for example: cm12.1
At least, you can try if there is no other options.

PLZ HELP!! Nexus 6p keeps booting into TWRP menu

Today and after deciding to simply restart my Nexus 6P, it booted into TWRP menu, I tried to reboot again, but no luck. can someone please help?
is there a way to get off the TWRP menu and boot my phone normally?
Note: The root used to simply work fine for about a month now.
Did you take an update? Rom details? You basically said you stuck a fork in a microwave and it sparked.

Have you tried wiping the caches and/or data? Have you tried reflashing whatever ROM you're using? Have you tried flashing the factory images with fastboot?

I will have to call you out here buddy. If you have indeed tried to flash all factory images, you won't even have TWRP in the first place.
Go to this wonderful guide by the wonderful @Heisenberg, and scroll down to "10. How To Flash The Factory Images (And Return To Stock)". You will find very clear instruction on how to return your phone to its factory stock state. This will most likely get rid of the problems you're facing.

If you had flashed the full factory images I don't see how it's possible at all to be in your current situation. Explain how you flashed them, and exactly what you flashed please.

Yes on the latest twrp. Idk what the issue is.
Would it be because I'm on 7.0? Idk if that's a thing but I would assume it wouldn't be the case.

Yes I'm sure I'm using the right one for my device. I have never had this issue before.
Went back to twrp 3.0.2.0 and it's fine, I guess it was just the latest release that was the issue.
