Huawei Honor 3C H30-U10 is dead?

vicfurpac · Aug 7, 2016

Hi. I think I killed my Huawei Honor 3C H30-U10 chinese version. I succesfuly had upgraded it to MUI 3.0 and latest Chinese FW, but then I tried to upgrade to anothr FW version european all ok, then I didn't like it and tried to downgrade to original Chinese FW but wanted to maintain EMUI 3.0. Now it doesn't vibrate anymore nor is recognized by USB. The only thing that I notice is when I plug the USB, A red light blinks once for just a short period less than a second right next to where the front camera is. Phone has no life. Tried everything I know to ressusitate the phone and it won't turn on, won't vibrate, and is not recognised by USB. Question is: Is it recoverable and if so, what should I do? Thanks in advance.

Hello,

try to charge battery to 100%. You can try a wall charger, so the phone did not use it while charging.

Hi, and thanks for your reply.

When you say a wall charger, you mean charging it via other way than using the phone itself? Because it doesn't show any sign of life other than the short red led blink next to the front camera and won't turn on. Therefore don't know if it's charging or not.
Before this issue it would vibrate if plugged to charger or pc, but after what I did mentioned on first post, it does nothing.

I could try to charge the battery directly connecting 5v DC to the battery's positive and negative pads, but it could be dangerous as it could over charge and blow as I would have no way to tell if battery is 100% full.

Any comments / suggestions are welcome.
Thanks.

Just try connecting the phone to charger and let it sit there for some time IF THE PHONE VIBRATES WHEN CONNECTED TO PC WITHOUT BATTERY. If it does so, you may try to flash bootimg with stock / last good known kernel.

Btw. The battery is charging using 4.11V DO NOT TRY 5V!!

Thanks for reply, but phone used to vibrate before I tried to upgrade it. Now it just does nothing, just a simple quick red led flash near the front camera.
Will try to leave phone on charger overnight and see if it vibrates again or not.

Hi guys,
I have honor 3c-u10. last week, I see that it was not working. so I tried to flash it. I think I had a mistake. now, when I try to turn it on, just black screen and vibration.
