Help How can I stop the device rebooting

Hi ! My device is stuck in the "bootloop" and I want to reflash with stock firmware. The problem is that for flash you need to shut down the device. This thing I can't only by pulling the battery or from the recovery. But when I plug the usb in my device, it turn on automatically( with and without the battery) and starts to reboot again until I pull the battery. The question is: I can flash while it reboot? And if not, there's possible to stop him rebooting?
 
What device do you have?

What you should do is pull the battery, wait a minute and then replace it. Then put it into recovery or fastboot BEFORE you plug it in. That should prevent it from bootlooping.
 
When is in the recovery mode, the reboot stops and stays in recovery until I turn it off or i pull the battery. I can reflash with stock firmware while is it in recovery mode? ( The device is Vonino, an american device, i have everything i need for the flash)
 
If you have a fully restorable ROM in a zip file then you can do it from recovery by using apply update from zip, or sideloading it using ADB sideload. If you only have the .img files for each partition, you'll need to flash that with either fastboot or the manufacturer's utility. I couldn't tell you exactly as I'm not familiar with Vonino.
 
They gave me, along with other files, SP Flash tool. It works while is in the recovery mode? And if it works, which version I should use ( because are 2): 1.15 or 5.15?

I understand that, but normaly, when i plug the usb in the device, it shouldn't turn on, right? In my case, it start to turn on. Appears the name of my device, after appears the error like the one in the image( it's not my phone, just the error that apears on my device too) and reboot and appear the name of device and so on. The question is that I can make the flash while my device is rebooting or is on the recovery mode with the sp ?

I don't know. Some phones will stay off in a charge-only mode, others will boot if power is applied. It could be because it wasn't shut down cleanly, but that's just a guess.

It probably won't work if it is stuck in a bootloop. Put it into recovery and give it a try.
 
Sounds like a Fastboot device. You need to boot into the bootloader, fastboot, or download. you won't be able to flash it in recovery. Wish I knew more about the device.
 
Thanx Bg260 for that tip! I installed the 15 seconds adb for fastboot( with his drivers too). When I enter the fastboot mode on device on the pc appears that some driver is installing, but at final appears unsucessfully. Do I need to install the drivers for my device too, not just the adb drivers?
 
The drivers are for the computer to communicate with the phone. If you are on on Windows look in the device manager. See if the phone is displayed. Could be under portable storage or a few other titles. When you find it right click for properties and then "update driver". Have you enabled USB debugging?
 
Try this ... put your phone into fastboot mode, then plug it in to a USB port, preferably on the back of your PC if using a desktop or a USB 2.0 port on your laptop. Even if it says drivers weren't installed, just let it go and open a command prompt. Navigate to where you have fastboot.exe and type
Code: 
fastboot devices
if it does indeed show a device serial number you should still be able to flash with SP Flash Tools.
