I bought a Cubot Power at the start of December, and I was quite happy with it for a while. Two days ago, I decided to install Greenify to test it out on a non-rooted phone, but when I tried to restart the phone, during the boot screen the phone froze for a moment and after that I couldn't do anything else other than stare at the black screen. Surprisingly enough, the next day my phone had it's screen on (had to insert PIN from restarting), and got to use it for a couple of hours. Then it froze again, and after that I haven't gotten it to work.
I'm not exactly sure what happened to it, unlike my previous phones it does not vibrate when turning on so it's hard to tell whether it's stuck in a bootloop. But when I do connect it to my PC with an USB cable, my PC starts making the device connect sound, only to disconnect a couple of seconds afterwards. When I open up device manager, I can even see MediaTek driver in there, which disappears with the device disconnection sound. I can't get into recovery, I've tried using the volume up + power button combination, but with no results (screen still remains black).
I've tried to use getdroidtips guide to install stock ROM on my Cubot Power, but no matter which stock firmware version I use, flash tool gives me an error "STATUS_DA_HASH_MISMATCH".
Does anyone have any suggestions what else can I try? It would be a hassle to send it back to get it fixed, as I ordered it from half across the world.

I am pretty sure that someone has posted something similar to my problem, but I can't find anything that gives a straight up answer or seems to kind of deviation of the problem.
So I do have cyanagen mod 10 stable installed on my phone and it has been great... No problems what so ever. I'm not sure if something happened or if it was something that I had changed, but the only thing system wise that I had changed was under the ROM Tool Box, I had edited the screen settings to change the dpi of the screen. However, everything worked fine after it changed and rebooted. In fact, I loved the fact that screen was now "bigger..." Meaning that it made the icons and text smaller.
So, now the problem comes, now the phone doesn't load up. The battery died and I plugged the phone into charge it and it turned on like normal with the little loading image of a circle (like the one you seen when a flash file is loading) and then it blinked and did it again, but then nothing. Normally if you let it sit for a second and press the power button, it would show an image of the battery charging. But it doesn't. If I press and hold the power button, it starts to laod up and says "Samung Vibrant" then goes black, and then repeats Samung Vibrant again and again....
Now I am not a super genius on the android thing, but I have flashed many different ROMs and thought I had bricked my phone many times as well, but always have been able to bring it back to life. I am actually starting to think of my phone as "Frankenstien" since it has died and came back so many times...
Now, I have tried to reboot into recovery mode but doing the volume + and - and power, didn't work.
I have tired to boot into download as well...
The phone can be plugged into the computer and it recognizes it as far as sending out a charge to "charge" the phone, but it does not recognize it in Kies or in Odin. I reinstalled the drivers as well and still not recognized... I know the phone is "old" as far as that goes, but it was working fine and currently unemployed, so every penny counts.
Suggestions?
Hi I'm really hoping someone can help me. I received a Sony z2 tablet spg521. I was told it was new but it would not power on or charge, and the charge light would sometimes blink red. Well I got the fixed or so I thought by doing a soft reset and then pc companion...sounded simple but spent a couple days trying to be successful. Sometimes my computer would recognize it sometimes it wouldn't.... Any way I finally got it out the blue dont know what the difference was I was just happy it finally worked... I then fully charged...yadayada and used it flawlessly for about a week... It would turn on and off, battery held charge like its supposed to, everything seemed to work.....then I went to power off but hit the restart by mistake....no there is no power again and this time it will not do a soft reboot.....no light ever....computer will not recognize ever....I have been trying off and on for a few days.....among-est my research to try to correct it seems like this is very common....when i shut it off the battery was over 50%..so how can something work fine then just die like this??? Ive seen that sometimes with sony if you disconnect the battery and the reconnect this will work... does anyone know? does anyone have any advice before I take apart this cherry tablet to try the battery thing???
I would really appreciate any insight as I have fixed many of my own problems and for others from advice on this site. Have a wonderful day and thank you!!! :silly:
ok today i tried to use flash-tool that Ive read about on this site....when it asked to plug n device computer recognized it and red light came on, but flash-tool did not recognize it....torn between letting it set and seeing what happens or trying to get the flash-tool to work, I chose the flash-tool...bad mistake when I went to try to reconnect and see if the FT would see it..it was no longer recognized by the computer and no light but computer did say USB device not recognized and not installed correctly.....now I already have the right drives so now Im really confused..tried a couple more times with same results and then once again nothing...no light no soft reset no recognized at all by computer not even not recognize USB....so disappointing loved the tab but this is insane that sony does this as its not user error but sony error and they dont even man-up and try to make it like you dumb or something....will try again..when i calm...
reset the device by pressing power+volume(up or down) for several seconds. It seems like a toasted one, possibly caused by putting magnetic charger on wrong polarity.
Thank you yes Ive tried all kinds of resets I have found...I agree seems fried but I would not know how. I have not used a magnetic charger...only the regular sony one that came with it....
So last few days I have tried off and on again....now computer recognizes by making noise when connected and disconnected but does not show up...PCC does not recognize it.....flashtool says its connected in log but when it asks for it to be plugged in it never leaves the screen telling you how to connect....when I try to connect the charge light comes on for about 4-5 secs then turns off....still no vibrate when try to reset still no light when plugged to a charger.....I want to get another one but I am scared this will happen again....gonna chuck this one as if time is money then I have well exceed the worth in time... I only got this because some time ago a sony z1 came my way and I so love it...i recently upgraded to z3.....i have a lg pad but screen got broke so I got the sony tab....maybe Ill just fix the lg

Mine is kinda toasted and this is how it works. Whenever I have a problem, I have to reset by pressing power + volume up, as soon as I hear three vibrations, I turn it on by pressing power button. Otherwise this tablet will just repeat sony logo and no boot. If you have bought one "NEW" make sure to return or replace it. If you want to enter fastboot mode, repeat the resetting routine and pressing power button to turn on, but also right after that or even simultaneously press volume up to enter fastboot mode with usb cable inserted, or volume down to enter flash mode. either way, your unit is toasted and sony sucks.
Well, I have the same problem, and isn't fun. Just very extreme rare cases it turns on the screen charging the battery, but doesn't turn on sadly
I did a happy boot today after 3-4 months off with several times trying turn it on, and did all the tricks from all treats about SOD
Last weekend I did a full charge from deep red to green light and battery animation on screen at start, but no luck.
I put it back in the box
This weekend I got some visitors, one of them asked about the tab, told him it didn't work and showed to him
Pressed the power button and to my WERY BIG surprise, it vibrate and turned on as nothing was wrong
The battery was only 54% after one week off. it received a update (264) and I installed as normal, turned off and on again as normal and happy I was

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.
Hi to all the XDA community,
It looks like that I am a new member but I have been for several year on XDA (but I lost all the log in details).
The problems I am facing is with a Samsung J6 that my mother in law gave me because one morning didn't show anything on the screen. These are the steps I did:
1. Screen is black, first thought lets charge it. I kept on the charger for ages. When I got back home I was sure that the phone is fully charged (it shows it on my usb hub). Tried to switch it on - Result, nothing is coming up to the screen
2. Hard reset by pressing power button and volume up or down - Result, nothing is coming up to the screen
3. Connect the phone on a laptop to check if the laptop recognises it. The laptop is doing the noise that something is connected and start installing drivers. Seconds later the device disconnected and connected again and this loop of connection and disconnection is happening for ever -Result nothing, only question marks.
4. Thought that is a hardware failure and since the screen doesn't shows anything I bought a new screen. I didn't by an OLED, I bough the cheap one. - Result, nothing is coming up to the new screen
5. I disconnected the battery and install the screen again connect the battery and try the same steps 1 & 2. - Results the same as the steps 1 & 2.
For me it looks like that the phone is bricked (I forgot to mention that my mother in law gave it to someone else before she pass the phone to me, no trust ) and the other guy probably tried to change the ROM or something similar. The boot loop that the phone is doing when I connected on my laptop is not normal (noise of connection and after 1sec noise of disconnection).
Additionally, I am not sure if the screen is working and I am on dilemma, do I have to return the screen to the seller of keep it until find out what is the problem with the phone. Maybe the screen is the faulty part that cause another issue. When I connect the phone on the laptop without the screen is doing the boot loop noise of connection/disconnection. I found out that when the phone is connected on the laptop and I press the power button the disconnection noise is delayed by couple more seconds.
Any help or guidance will be more than welcome.
Obtain the Stock image for your fone from samsung, load it into the version of Odin they suggest, but dont start it yet.
Disconnect fone from pc, and turn it off.
Start Odin flashing
plug fone in
Mb a few steps dif since I last flashed a samsung, but this will fix your fone.
Make sure you got the samsung driver installed in your pc

Thanks for your response.
Samsung drivers are already installed.
The problem that I am encountering is that I can put the phone on download mode. Firstly because I can't see anyhting on the screen and secondly because my laptops can see the device. I tried different cables too but nothing worked.
Since the phone cannot be recognised by the PC, the Odin app cannot see it either.
As the title suggests I have an old Z2 tablet that has been an absolute work horse for many years. I was using it one night and the Android OS prompted me that the device hadn't been rebooted in 28 days. So after I was done using it for the night I rebooted it. Only, it didn't reboot it just stayed off. I tinkered with it for a while and got it to show the Sony logo but then it just went dark again. The device is rooted and I have TWRP on it. So when I got it to turn on again I booted it into the TWRP recovery. I proceeded to clear the cache and also attempted to make a current backup. However, the backup would fail after running for several minutes. I decided to try backing up to an external OTG USB drive but the device needed to be rebooted to detect that the OTG USB drive was attached. So from TWRP I selected "reboot recovery".
Unfortunately that was the last time it worked. The screen will not come at all. When I hold volume+ and power it vibrates 3 times but still doesn't boot. I plugged it into the charger even though the battery charge last showed at 85%, but with the cable connected the charge light doesn't even come on. I tried plugging it into my computer but it doesn't detect the device has been connects and adb devices doesn't show anything in the list.
I read on a forum to try drying it out with a hair dryer and while the device hasn't ever gotten wet it has been humid here so I figured what the heck. Unfortunately that also hasn't resolved the issue.
Pretty much everything I've tried hasn't worked. Even the red reset button under the top panel just causes it to vibrate 3 times.
The device has been in this state for a week now. I was hoping maybe the battery would die and then I could recharge it, but since it still vibrates 3 times I'm guessing the battery still has a charge.
One thought I had is that maybe the internal storage is either dead or corrupted.
At this point I'm wondering if the device is a lost cause and I should just let it rest in peace or if there's any other solution. Even if there was a way to factory reset it from it's current state that would be better than having it be a paper weight.
Any suggestions beyond what I've already tried would be greatly appreciated. And, yes, I may look into seeing if I can get it serviced however there's definitely no warranty and I don't really want to poor money into it since it's probably time for an upgrade anyway.
Why is my phone vibrating 3 times and won't turn on? - Sony Xperia Z5
When I try to turn my phone on it just vibrates 3 times and does nothing after that, just wondering what the problem could be?? - Sony Xperia Z5
www.ifixit.com
The device vibrated 3 times, that's good, then it is off.
"Sony writes: This is how you force the device to turn off:
Press and hold the power button and the volume (+) button simultaneously until the device vibrates three times."
Did you try to put the device into flash mode after that? I think only a complete flash will bring the device back to life.
