Hi All,
I have flashed EUViewPad 7 based on Stock rom. installed SD Card Booster, CPU Master and etc.
The flash is fine since I managed to boot it and install several apps.
Until I needed to reboot the device since the hacker keyboard always forces to close. I rebooted it and poof I am in infinite boot animation without a way to remove the battery. afraid to fiddle just waited the battery to drain so I can test again(This happened on my O1. just removed the battery, put it back and its ok)
I have drained the battery after almost 8 hours of non stop boot animation. But this device won't turn on anymore. It just vibrates when I press the on button.
Tried opening the back(crap I have scratched the back covering. now it has large scratches ) but the battery is taped . My question folks is what is the possible solution to my problem aside from removing the battery(can't even get to clockword recovery)
Thanks
Not too sure about your device, but doesn't yours have a reset button like the viewpad?
Should be a small hole on the bottom edge right next to the microphone.
Try pressing that with a paperclip if you're having boot problems.
Anyway, if you've drained the battery completely, make sure to leave it charging for a little while. Too low battery voltage will make it unable to start. 15 mins or so should be more then enough.
Try starting with both volume buttons + power pressed. Keep holding it until you see "entering recovery mode."
Let me know if this gives any results.

Ahh I have that reset button beside the microphone hole. Will try this later on. Thanks for your help and for your custom rom
Uh oh... Tried pressing the small hall beside microphone, pressed on button. No luck. tried pressing that hole and on at the same time No luck again.
Is it possible that it will mess up the whole boot process due to boot animation loop??

I'm afraid and it sounded like, from your descriptions, that the boot process has been messed up .... so, what do you got to lose by trying to "wake" it up or at least respond to commands, right ?
Try holding the power button & use a small pin to press RESET - leave it connected to the power supply/charging unit.
Try holding both volume Up & Down key & use a small pin to press RESET
Try holding both volume Up & Down key along with the Power button at the same time, and press RESET (you might want to get someone to help you to this)
Try holding the volume Down (left) key & Power button, and press RESET with a small pin.
Does any of these work in getting the screen to show life, be patient as you might have to hold it for 10 to 30 seconds before it cycle & restart/display the 3 birds ...
Chances are you will need to flash a stock ROM with the SULT3 utility, and then if successful, root it again & start over (carefully) - it might work or it might not even connect via usb at all .... worth a try, got nothing to lose at this point.
As a last resort, contact Cherry Mobile and get it repaired & sending it back to the shop .... check the warranty details in your locale, opening the rear case & exposing the battery, might or might not void your warranty coverage.
Hi Letiride,
I have tried the combinations you have specified but no avail. I can't boot this so my PC with correct drivers cannot even recognize i plugged this.
Is my Tablet already bricked?? I have bought this second hand so no warranty already.
Huhuhu Did I already have one of the "Vibrator" Android phone

Oh mine, no - if it won't power up or boot into Recovery or FTM mode, I'm afraid it's critical if not officially certified "paperweight". Try uninstalling your PC's usb drivers for the device, or use another computer & install SUTL3 utility from Viewsonic, and see if it can at least beep & signal some USB sequence loading the drivers.
Here's a link to Droid Explorer posted elsewhere in XDA (instead of pointing you to "Search" for it) Install it if you can get the yours powered on, but use it with care as it's a very "powerful" tool to explore all the hidden workings of the Android device(s).

My feeling is that the core image & boot file(s) were corrupted, damaged & overwritten, and it need to be reformatted & reflashed from a stock *.nb0 file, someone with adb might be able to - maybe, just maybe - rescue it.
Let's see if one of our fellow developers might have a better solution on where to begin b/c this is about as far as I can offer - well, you can always put on eBay for parts & hoped you didn't spend a lot as 2nd. hand.
Uhhh looks like i have no other choice but to have this repaired at service center and pay
I've got a Chinese tablet that boots properly up to the unlock screen, where if I'm quick I can unlock, I can see wifi is connected, etc. but around that point it completely freeze, even the power button doesn't turn off the creen and I have to reset it by long pressing the power button.
I tried all combinations of keys to bring up a recovery (power + volumes) without luck so far. If I press any volume or back key while powering up, the tablet doesn't power up and stays black. adb isn't finding the tablet. I opened the tablet, there are pins to connect a rx/tx serial. I could do connect a serial adapter to it if that could be of any help.
Actually, at this point I don't care much about the tablet but that could be a good opportunity to start learning a bit more about Android hardware development, just don't know exactly where to start.
Any tip?
Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks
Samsung Galaxy S9+ No custom, Just a normal phone from T carrier.
The situation is as follow. I wake up everyday and cannot turn on my phone, the screen is black but I hear it beeping when i press the volume keys. I do a Vol down Power to restart thinking it will , it restarts but the screen is black and unresponsive no matter what I do, the Power button is still functional at this moment.
What I quickly did is I connected the phone to my monitor using USB-C and i have a mouse connected to the internal KVM of the monitor- , perfect got excited that the phone at least works, on the monitor it shows up perfectly, I can control the phone with the mouse, enter my 4 digit password, works. That was the situation yesterday. Should have backed up then but didnt.
Today I wake up, the Power button does not work, so I read and find out that I can go downlead mode which I did using the Vol down and Bixby and plugging the charger.
tried the Vol Down and Power to restart it does not, so again I go in to the download mode and accidently press Volume up, Now I am completely stuck on Downloading... Do not turn off target
1. Power button does not work- I have no idea how to get the past Downloading screen now
2. Would I be able to recover anything it its really dead?
3. Any tips?
Hey everyone,
I have an issue with the bike tablet no longer turning on.
Previously, the bike wouldn’t boot past the P boot loader. I got it into fast boot with Power + Volume Up. There, I went to recovery. This presented a screen with an error robot and text “No command.” I powered the device off, planning to go back to fast boot and try something else, but now I can’t get the device to turn on.
I’ve tried
- holding the power button for extended periods of time
- holding the power button + volume up for an extended period of time
- directly connecting the power to the monitor
- unplugging for several hours to let batteries and capacitors drain
- using adb. Adb does not see the device, though windows device manager does recognize something is connected via usb
Ultimately, the screen is a large Android tablet so hoping someone could help out. Any suggestions?
