Reboot and RED LED. I know red means bad and i dont have any idea whats wrong.
The whole problem is described in the title.
Some details:
I switched my battery with my friend who has a prophet also. Problem remains the same. When i connect USB or wall charger device switches off and RED LED appears.
My battery charges on the other devices (friends prophet).
Is my dev bricked? Whats wrong ?
Im using ShadoW 1.0 (clean edition) ROM (WM6).
I know that the ROM in my dev is working because when i charge batter in other device and put it into mine - dev boots up and works normally.
(tryed also in boot loader mode - switches also off )
Question: what happens if you try to charge the device while it is off (completely off)?
There may be a problem with the USB driver in which case the device should still charge normally when it is off.
If that is the case try another ROM, or at least a hard reset.
Hard reset already. cant connect to any laptop with usb because every laptop will make the device switch off, even when i boot in RGB mode (boot loader) - thus cant change the rom :/
Hi. I've the same problem.
My prophet walking strangely.
1. When I plugged into a PC he does not want turns on. When he turns on, it for some time.
2. When it is in charge, the red light 3s, then sometimes it goes boot loader mode, once it does nothing else
3. Without battery it is the same.
same problem
any solution for your problem???
My phone was stuck in the connect to PC (phone..!..PC) screen after being left in download mode for the night.
I connected it to the wall charger and when it showed that screen, I turned it off, I turned it off a few times and then connected it to the USB and use heimdall "close-pc-screen" option to recover.
Wanted to share this if anyone faces something similar.
2.3.4 - unlocked/rooted
Tried several PCs/Macbook. Tried several cables...
Plug the phone into USB and it charges but isn't recognised by the PC/Mac and phone does not recognise it's connected to USB.
Also, power off phone when it's connected to USB it hangs just before powerdown. Progress stops spinning and it sits hung. Unplug USB at this hung point and it powers down immediately.
Boot into recovery mode (Power/Volume up) and connect to USB - Reboot bootloader still not recognised by PC.
In recovery choose Power off whilst USB connected, again it just hangs - 'POWER OFF' highlighted in blue to confirm selection, but phone just hangs at that point unti USB disconnected, at which point it powers down immediately. It will reboot if you choose reboot option from recovery menu...
My phone won't transfer data but charges too. Except mines is a hardware issue. Dropped the phone on its USB port while plugged in. All loose now
Sent from my Nexus S 4G using xda premium
Installed cyan rom. No difference.
Phone still won't shutdown when USB plugged in. As soon as you remove USB down she goes immediately, so as I suspected it's deeper than a ROM issue.
Boot phone into standard recovery mode with USB plugged in, Choose reboot bootloader, info messages displayed
USB Control Init
USB Control Init End
Top line shows 'FASTBOOT MODE'
Still not recognised by PC/Mac.
'ADB devices' shows no devices.
'fastboot devices' shows no devices
Searching around this seems to be a 'known' issue, but the fixes I've seen documented say power down phone whilst plugged into USB, which obviously I can't do as it hangs.
PITA this as I use it as an app development phone
Was plugging in my G2 to charge it and suddenly it had this screen. "Firmware Update. Do not unplug the USB connection until the process is complete."
How do I exit safely? Will I corrupt any data or damage anything? I was only plugging in my phone to a wall socket, so I don't know why there would be such a screen. Help anyone? >.<
Someone knows how I can exit safely? >< Please?
That sounds like its in download mode, which you get to by turning off the phone, then plugging in a usb cable while holding vol up. I always assumed the usb cable needed to be connected to a computer for that to happen, but maybe it works if it just senses power.
Anyway, if the bar isn't going anywhere (and it shouldn't be since its not connected to anything feeding it data) then you should be okay unplugging it and turning the phone off, then back on.
Edit: Just tried it with my phone - turned off, then connected USB cable/wall charger while holding vol up and sure enough it went into download mode. I unplugged the cable, then held the power button until the phone restarted. Booted as normal.
My Lg ls740 prompted me to do a system update 3days ago and has not came back om since. It just keeps flashing from LG logo and the android man...i have tried taking battery out...factory reset...and everything above . Can anyone help?!?!
Okay, weird problem here. I'd like to unlock the bootloader on the Samsung Galaxy Tab A 8.0 2019, but can't seem to recreate the blue screen asking if I'd like to enter download mode or unlock the bootloader. I've read that I should press both volume keys and plug in the device while holding the keys until that blue screen appears. However, for me this doesn't do anything except "boot" the charging thing (where you see the current battery percentage), I held the keys for about 30 seconds but didn't get anything different. When I press Power + Volume up I get that Android Recovery screen, but can't seem to unlock the bootloader from there either. I tried rebooting to bootloader, but that just gave me the download mode instantly (on a black screen with my tablet logo) - this way I also had no choice to unlock the bootloader. Anyone know what I should do here? I'm kind of stuck
Edit: fastboot oem unlock just tells me it's waiting for device, however adb can find my device (OEM unlocking and USB debugging is on)

With the tablet off, plug the cable into a PC only. (not a charger) Then, while holding down both vol up and down, plug the cable into the tablet. After a couple of second, the screen should appear with the unlock option instructions.

I am doing that, but the tablet just shows the charging animation that appears when the device is off. By the way, the device is on Android 11, is that maybe the problem somehow?

It has nothing to do with what version of Android you are on. It should enter the download mode before Android even starts to load. Have you tried using another USB cable? They can be very touchy about detecting the data connection rather than just power. As I said, I don't have a 290, but on my 500 it helps to connect to the PC via a USB 2.0 hub rather than directly to the PC.

I now tried 3 or 4 different cables with no luck. I'm still assuming that it has something to do with the software, and I noticed today that the tablet actually runs OneUI Core, whatever that means.
