Hey,
I'm in the process of using SP Flash Tools / scatter files to try to recover my phone from what I think is a soft brick. My problem is this:
I can't power on the phone, enter recovery or fastboot. When I connect it to a PC via USB cable, it connects and disconnects every 20 seconds.
I've tried different cables, different PCs and different USB slots on each PC.
I've tried connecting with the battery in and out; no change.
I've tried removing SD and SIM card; no change.
When I'm going through the process of SP Flash Tools, it recognises the phone and starts downloading the scatter file to the phone (once the PC detects it) but after 15 to 20 seconds, it fails, because it disconnects form the PC.
Any thoughts on how to solve the connect/disconnect issue?
Cheers,
Chris
Try to charge the battery up as much as you can. Maybe you don't have enough juice to keep it on.
Thing is, it was on about 80 percent when this happened (using my phone then all of a sudden it froze / turned off) and it's been unable to boot since. I'll charge it for a few hours and retry.

Well, that sounds like an emmc fail. I had a similar thing with my Nexus 7, only a motherboard swtich solved it.

Does that mean it's a hardware issue? How sure are you that that could be the cause?
When I plug the phone in to charge, the LED lights up red for about 1 to 2 minutes, then turns off. No change with regards to power button not working etc.
Is this indicative of something else?
Cheers
Hey,
I'm afraid I also faced a sudden hard brick today
Did you find any solution? How did you proceed?

Ive tried searching everywhere on here but cant find anything concrete. Hopefully you can help me out
Verizon - Samsung sch-i500 fascinate.
It has been running Dirty Unicorn. Its the only one that's lasted for more than a month. All of a sudden the other day it started having problems.
The phone with battery in and just power button keeps putting into Download Mode. The only way to remedy it it to hook it up to computer with USB. While phone in hooked up it charges and everything is fine. The moment i pull the USB cord off it gets super sluggish like 50 mhz cpu or something. Then after about 3 minutes it crashes to black screen and i have to reboot it with the battery and usb hooked up. USB & Battery in pressing p. button it will boot up perfect and run again until i pull the usb. Also when rebooting with the p.button only and USB/Batt combo the first thing that shows up is a charging battery for 5 seconds then it reboots automatically into Recovery. Then I select reboot system and thats when everything works. Ive tried recovering OS and even tried different recovery flashes with Rom Manager.
USB debugging is on although the icon isn't there when cable up. Phone will charge.
I tried doing ODIN to reformat but ODIN wil never connect to it. I'm running the Samsung Driver that worked before. (Tried uninstalling and reinstall)
This leads me to believe its a USB issue somehow. That's why I'm here.
I just want this thing to work without being hooked up to USB.
I installed the stock rom through twrp and it seemed to work ok.
I then went into twrp again and tried to use it to wipe the sd card, which didn't seem to work. So i then tried to have it repartition the sd card and that also failed. At which point i turned the phone off - and havent been able to get it back on since.
however, i think the phone is actually still on in some way. When i plug it into my pc, it detects that the phone is plugged in, which it shouldn't do if the phone is actually off. It's been less than 24 hours since this happened so I'm sure the battery could still have juice in it.
Anyone have any ideas what went wrong here? And how i can fix this? Or did i just brick the phone?
What does the phone show up as when you connect it to your computer?
Nothing shows up in file explorer but under ports in device manager it shows qualcomm HS-USB QDLoader 9008 (com3)
That's not good
how not good is it? Did i just create a paper weight or is there some way to fix this?
Any ideas what I did wrong? Like i said, the stock rom installed. This only happened after I tried to wipe/repartition the sd card in twrp.

You may be able to resurrect it via Jtag but that's out of my realm. Have you tried charging it overnight or holding the power+volume buttons for two minutes?
I've tried just holding the power button down for a minute but nothing happened.
I was actually thinking i should let the battery drain since right now it appears to be turned on to some extent since the PC detects it when i plug it in. The battery had about 80% full charge when it died. So i didn't think fully charging the battery would help. (tried doing the power button and volume button now, no effect)
jtag is new to me - just did a quick google search. Looks like it involves opening the phone up and shorting out some pins?
I wish I at least knew what the hell I did that caused this

I believe captain had a similar situation on his m8, tired to partition his SD and made a very expensive, yet very visually pleasing paper weight.
ah shoot - i didn't think anything dealing with the sd card could muck it up. The phone will work without an sd card normally doesn't it? Oh well, guess I'm out of luck now
Hello all. I have a Smartbook Surfer 360 mn 10u. It went a bit haywire recently so I reset it using the desktop options. Since then, when I power up, all I get is a blank screen followed by the jelly pad logo and that's how it stays.
I've opened the back and disconnected the battery. I reconnected and let it charge before powering up, but the same thing happens. I've tried connecting it to my laptop with an a-a USB cable but the laptop doesn't install the drivers.
Does anyone have any suggestions as to what else I could try?
I would really appreciate some guidance as this is driving me nuts !!
Many thanks

power it up and then wait for long hours about 4 or more hours to boot just wait
then if still not working remove the battery and wait 20 seconds after that plug in the charger without the battery then wait for 20 seconds again after that
remove the charger then put your battery in your device and then plug in the charger then power it up
Boot loop problems

Hi Cedie,
Thanks for that. Unfortunately this has not resolved the issue. Is there anything else I could try? As i mentioned, I have tried connecting it to my laptop to see if I can access it from there but. When I plug it in it starts installing the drivers, but then fails.
Is it safe to say it's for the scrapheap or is there anything more drastic I try?
Many thanks

turn it on for long hours
Hey there. I found a bit old phone in my house, Huawei G730-U10 with MTK6582. Here's problem:
Phone won't turn on at all (no reaction) with battery in and USB out.
With battery in and USB in (connected to charger or PC, no matter what), at first it turns on red led that stays still, and after some time it starts vibrating with interval of about 10 seconds and PC sees it for 2 secs (it connects and after 2 secs - disconnects), then everything repeats. I assume it's bootlooping, but there's no anything on screen (it doesn't even turn on, full darkness). This continues even after taking out USB, only way to stop it - take out battery and place it back.
With battery out and USB in, red led starts blinking with very quiet beeping (very very very quiet).
As you could guess - recovery, fastboot and other things aren't working.
I've checked main board, everything is ok, connected and working fine.
I think there's problem in ROM (not firmware ROM, but ROM that's read-only memory). Something's wrong, maybe there's wrong preloader (or there's no preloader at all), maybe boot partition is damaged, I don't know.
Service center tried to fool me on buying new board for 100$ (althrough it costs 40 on aliexpress), I think they didn't even look at it, so I can't trust them.
I don't need suggestions like "try to flash new rom", you think I didn't try? How is this possible if I can't make PC to see phone for more than 2 secs? Flashtool isn't working even without battery mode.
Do you have any ideas?
Thanks for help.
Hi i purchased the phone in January the phone has been working fine no problems at all until last night. I was playing football manager which i imagine is quite a heavy game to play but something i do regularly and have no issue usually. i got a text so i switched to whatsapp and the phone crashed, so i did a hard reset holding the power button down and it booted backup but then crashed again immediate.
tired to do the hard reset again but it just went to a black screen and haven't been able to turn it back on again since.
so basically the phone is non responsive to anything i'm not getting a charging sign or any sort of sign the phone is working no vibrations sound nothing. the battery was on about 80% before it went of so pretty confident that's not dead.
things i've tried so far:
Hard reset holding down the power button
boot select holding down the power button and volume down button.
I've been trying to connect it to my laptop now this is a slight positive but where i've come up stuck, the laptop makes the sound as if its been connected then 5 seconds later it will disconnect then reconnect disconnect and so on.
I've changed the power setting for usb ports no change, i've tried holding down the power button on the phone as to reset it incase it stuck in boot mode or something but no change.
My next step is to take the back of the phone and remove the battery for 30 seconds or so. but with the phone still being under warranty i'm a
bit reluctant to do that plus i'm pretty confident its a software issue.
Update: after deciding to open it up i've disconnected the batter and the screen plugged it in and still getting the same connection/disconnection issue. it will connect then disconnect within 5 seconds max thne connect and disconnect. thought disconnection the battery may do the trick as i haven't tried to flash it or anything like that just gone wrong on it's own. I've now voided my warrenty but want to get this sorted anyone got any idea as to what could be causing the issue?
Thank you for taking the time to read it all and suggestions are appreciate thank you

Thanks for replying, that's what I've been trying to do but the phone won't stay connected to a pc. I connect to the pc and it will disconnect within 5 seconds then reconnect disconnect just constantly doing that. I thought Maybe if I unplug the battery it may get it out of that loop but even with the battery disconnected as soon I connect it to usb it still does the same loop. It hasn't got any lights or vibrations, to look at the phone it's non responsive thee only response I can get it the computer connecting and disconnecting constantly.

That mean that, your phone is waiting for flash and when it don't get it it just restart and do the same think. It happended to me when i flashed wrong twrp. Just select firmware in sp-flash tool and click download. Than plug your phone into your pc and wait for next restart. If nothing happens you will have to download mediatek drivers.
(My english is really bad, i really sorry) Hello good evening. Excuse me, did you find any solution? Did you request a guarantee from UMIDIGI? What happens is that I was charging the phone and started watching YouTube, in an instant the phone went off and did not want to turn on definitively. It does not respond to my PC or the charger.
I clarify that the entry is good, I had 40% and I set about the task of looking for more problems of this style and I found two similar to mine, and yours would be the third problem that I see of this nature. Should I contact support and ask for a guarantee? I don't know what to do. Thanks.
