Big Problem - after connecting USB or wall charger - switch off.

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???

[Q] Not powering on - please help

Omnia 7 with Mango RTM officially installed, working perfectly was recently let to sit idle while I was using my Focus, and the battery drained over time.
Today, I wanted to charge it, but plugging in the USB did not power the phone on. I even changed cables, and also used my PC to charge it - but for the life of me, it wouldn't turn on. I even let it sit with the charging cable in it for a while.
I also took the battery out and only plugged the cable, still nothing.
Is the phone dead? Can anything be done to revive it - it was a flawless phone and there were no issues as such. I would appreciate any help.
Update: I plugged in the USB jig which powered the phone on, but now it's in the download mode. Powering it down and and trying to restart it again I am hitting a dead end. It's not powering on. Anyway to restart the phone without removing battery?
Update 2: I remembered from the past trying to update the ROM, that it fails and restarts the phone. So, while in the download mode, I started the ROM updater from Samsung and ran through the normal update process. It failed and restarted the phone - now I see a big white battery charging icon on the front screen. So hopefully this will be ok - and I will update the progress.
But this is quite disturbing as to what steps I had to take to power it on. Imagine if I didn't have the USB jig.
Update 3: After showing the battery icon for about 5-10 minutes, the phone restarted itself and booted normally. It's now charging and hopefully all will be ok. I'll make sure I don't let the battery die again.

Battery charging problem (lenovo k3 note)! Please help!!!

Hello,
I have a problem with my lenovo k3 pote phone.
I put the phone on charging (AC) and after a while I noticed the phone was turned off. When I tried to turn it on, the phone just vibrated and nothing happen. I changed the charging source (to my laptop) and the phone was not charging. After many attempts, the phone turned on and I managed to reinstall a MM rom I was using ( K3_NOTE_MM_6.0_1610_3.40.1_v16_ROW_D_CUOCO92). I even tried to restore to the previews rom (default rom) but the phone turned off while it was restoring.
Now the rom installed is K3_NOTE_MM_6.0_1610_3.40.1_v16_ROW_D_CUOCO92,.
Now the phone turns on only when it is connected to charging and the battery shows 50%, but it doesn't charge.
If I turn the phone on without connecting to a charging source, it says 1% batter and it turns off within a few minutes.
When the phone is turned off and I try to charge it, it shows the charging animation for a fraction of a second and it disappears.
What should I do?
I was thinking to install a new rom (CM12 stable), if I can and hope to solve the charging problem.
Please help !

Update:
I installed the CM12 stable (http://cu.tl/cm12) and the phone can only be charged while it is turned off but it doesn't charge when it is turned on.
Please what should I do next?
Edit: now I can tell it's not only me. https://forums.lenovo.com/t5/K-and-...novo-K3-Note-Not-Charging/td-p/2145929/page/4

battery not recognized

Hello,
My yotaphone had some big issues after I've changed earpiece, the actual situation is:
- With plugged battery phone is completely dead, nothing happen pressing the keys and the pc recognize it as an usb input device (no adb/fastboot support)
- If I disconnect the battery connector and then plug in the charger, phone starts a bootloop "powered by android", BUT if I plug in battery DURING bootloop the phone boots correctly to the system but battery is 0% (I bought a new battery and I'm sure that there's some charge stored) and if I disconnect charger it says battery low and tuns off
- I've noticed that if I put phone in download mode>connect battery and then disconnect charger, phone stays on and it happens also during "optimizing apps" step during the first boot after update.
Now, I'm not sure of that but I think that it's an hardware issue (like the "daemon" that reads battery amperage doesn't work anymore) but I need your help tho confirm this supposition and even some things to try before throwing away my beloved yotaphone 2
p.s. sorry for my english

My YP2 has had problems with QI-Charging and random reboots since two weeks, maybe from falling down..
Two days ago, the YP2 got very hot, the battery has blowed and the YP2 was in bootloop.
After changing the battery, the YP2 will run like new again.

problem identified!
Finally I've discovered what's wrong:
battery connector is partially broken and the central contact doesn't touch battery terminal.
anyone have an idea if I can find this connector or if I have no chances to find it?

[SM-T230] Tablet doesn't boot if not pluged to charger + doesn't charge if turned on

Hi Everyone,
I just got a little SM-T230 tablet and started to playing a bit. I flashed TWRP, changed rom, rooted, tried some mods and it became surprisingly good and snappy. So thanks again people here at XDA you are awesome as always.
But the tablet has some strange problems. When I try to turn it on, it keeps flashing the Samsung logo with the model number. It shows up for a few second after that goes black and shows up the logo again and repeats this for ever.... But if I plug in the charger (wall charger or laptop usb port, doesn't matter) it boots normaly. When I plug out the charger, no problem I can use the tablet normaly, does not turn off or anything. The battery is quiet good, it can play video continuously for almost 6 hours. If it fully charged the situation the same, I have to plug it in to make it turn on.
Another problem is, that the tablet doesn't start to charge when it is turned on. But if I turn it off and then I plug in the charger, it starts to charge, and after that if I turn it on, it keeps charging.
Do you have any idea what is wrong? What can I do to fix these problems?

I can't figure it out what is the cause of this problems. I flashed 4 different roms, stock and customs, but just the same with every rom. Can it be a hardware related issue?
Edit: A little update on the charging issue. I flashed CM 14.1 for T230 and now charging is working, I can charge the tab when it is turned on. But the boot problem still here.... I can turn on the tablet only when it is pluged to the charger.

You're lucky
My SM-T533 was hard bricked because I flashed a rom and I'm still searching for a Kitkat Debrick file, if someone would give it to me, that would be awesome
