[Q] Bricked Verizon G2

I made the mistake of wiping TWRP from my phone. I did a factory reset when I booted into TWRP. I tried installing the camera app mod. I am on 4.4.2. I am currently stuck on the LG screen and the phone will not power down. I cannot boot into download mode or recovery. I have tried to research as much as I can from other threads and I cannot find any that match my issue. Do I need JTAG service to fix this?

Hm. What exactly did you do ? How did you lose download mode ? (recovery I do understand).

While my phone is stuck on the LG screen (the phone will not power down) I hold the power button until it powers down, and it automatically reboots. When it reboots I hold the power button and the volume down button when the LG screen reappears and it just reboots again. Thanks for the quick reply. -Josh

Good news I just hit the right combo of keys at the right time and I got into TWRP. I will update this as I progress. I got it solved. I restored from the backup I made. Thanks again.

[Q] Bricked Phone, Cannot Enter Recovery or Download

I appear to have bricked my phone while trying to get back to stock firmware. I am using a galaxy s4 on verizon with windows 8 for reference. My problem is I cannot enter download or recovery mode. When I try to enter either of them it flashes for a second and then disappears. After that I have to remove the battery because the phone won't respond. The same thing happens on a normal boot so I am stuck. Also I am noticing that the phone boots up on it's own when I put the battery it. Could the power button be stuck or something? What can I do to get the phone back to working order?
POWER BUTTON FIX: Ok after some more research I found this which solved my power button problem (Can't insert the youtube video until I have 10 posts) but you basically flick the top and bottom of the phone near the power button to fix it.
Now I am able to go into recovery and download modes

Great mate!!
Glad it was easy.

[Q] Can someone help with the solution?

Hey guys,my phone will automatically turn itself on when i insert my battery. Then after the Samsung logo, the screen automatically turns black. I first suspected that it was a battery problem, but that did not turn out to be the case. I think it has something to do with the power button. I also tried to boot it up into recovery mode but the screen still went black before i had the chance to do anything. Any help would be appreciated. Thanks

Even with the charger on?
Why you said that the battery is ok?

It's definitely a stuck power button

Try to let the battery drain and make the phone die, then try to charge it when its off and get to download from when its off.
Also have you tried a jig to get into download mode and stay there?

Hi Thanks i forgot to scroll down and see its fixed Thanks a lot bro sorry i researched for hours but i couldnt found that forum Thanks again:good:

Recovery is a blank screen, so is the os!

Hello,
I need some guidance. I flashed the latest version of malaysk ROM. Unfortunately both recovery and the rom give me a blank screen. I know the screen works because I see the malaysk logo when I attempt to go into recovery.
I am presuming I could use a PC and fastboit mode, but how is this fine on an android head unit.
I have a 1 din, flip screen type, KLD5, RK3188 model.
Please help me.

There seem to be a lot of units flashed with the latest rom that have lost the bootloader and recovery.. I'm not seeing any fixes for this. Has anyone fixed a unit that is now stuck at the bootloader with no recovery possible?

I did not try it, but this might work:
Holding the power button while turning on the unit will get you into bootloader mode. **This is battery power not acc power** The screen will be black but plugging in a usb to the front usb will prompt the PC to install the RockChip bootloader drivers - this might help http://www.cnx-software.com/2013/11...install-rockchip-usb-drivers-in-windows-xp78/
(From http://forum.xda-developers.com/wiki/Hui_Fei_Type#Bootloader_mode)

I don’t have a power button on my HU, I wonder if the RST button or the smaller reset button above would work?
