android reboots repeatedly - Android Q&A, Help & Troubleshooting

Hi all!
device is a tablet,Vero,Oktabit,Chinese make,model no:A8878
on the cpu i found : A33 Quad core Q88 E8024AA 2951
The device has on the ic q88 A33 8G 2681 7660 512M
SP 1409025 3032
LZ 87 20140930
Installed was the kitkat4.4 ver.
After installing some application ,it started rebooting continiously,without responding to button presses,except to shut down when pressing power button for 10 seconds.
I tried several combinations of the volume and power buttons(the only ones it has),to no avail
I read it is possible to flash this thing to make it work again,but i cant find the image file needed according to the instructions i got.
Do i need to get a specific file or any kitkat 4.4 for a tablet would do?
And how am i to go about flashing it?I need an external SD card and reader??Or is there an easier way?
I d appreciate any assistance
Best regards in advance
GS

Can you please tell me what apks you had installed before getting into this??

prestigio pmp 5588 C duo (MultiPad 8.0 HD) root

well, i hope this will pass cause I am a noob here..
As an owner of this pretty much cheap and quite alright device I had hard time finding proper root method but in the end it was found..
Mine was already on 4.2.1 and the rest is as usual 1,5ghz dual core, mali 400 graphics, and apparently cortex a7 not a9 as on the box.. but who cares, right!?
so i got to the file (its actually based on crystal_root method from xda but some smart guy somewhere just made it work for 4.2 generic tablet ) I apologize if this si mentioned somewhere else, and I couldn't reply to crystal root board cause i am a noob, but I am sure some people will find this useful, that's all.
ok...you can chat here with me untill i got those 10 posts to upload link, you can google "Aigo M80E - JB 4.2.1 - help with rooting (killing cell standby)" or you can be a good soul and my first mate here and paste link
Cheers!

Prestigio 5588c Rooting Issue
Hello to all.
I have a Prestigio 5588c and I had recently updated it to the latest firmware. I wanted to root this device, but it seems that the new update is not allowing the utoo-root-signed.zip to root it. It keeps failing. I was wondering if there is someone out there that is in the process of renewing the file so that it works on the most recent update from Prestigio.
Thank you in advance for your time and your great work regarding all things that are Android

Hello all,
I have the same PMP5588c_Duo device (4.2.1 stock Build PMP5588C.20131231.1.0.42) and managed to easily root it using Kingo root (kingoapp.com). It's a straighforward process:
download the app and install it on your PC
enable USB Debugging from the Developer options on the tablet
start the app on the PC
connect the table and PC with a microUSB cable
do not enable anything else on the tablet (like SD card access)
wait for Kingo to detect it
it will automatically download and install USB drivers to your PC and show a ROOT button
click the ROOT button, wait for 2-3 minutes, it could take up to 10min so be patient
the device will automatically reboot after the root has been applied
at which point disconnect the device
after the restart check for the SuperUser app, it will automatically install it
Have fun.

hey Z.
thank you for the guidance.. testing it now so will update shortly.. although the program thought I had a samsung note lol
ok, this is an update.. seems the program did not want to root my tablet. when I started it again, it classed it as a google device, but said connection failed due to cable instability.. guess I will have to try another way
double update... after leaving it for a few days, it seems to have wanted to work.. woohoo. thanks Z for the info
help with prestigio multipad 8.0 HD !!!
Welcome. I have a problem with this tablet.
Tablet died after a crash. There is no option to enter a Power + vol +
also does not move with the micro SD card from the system manufacturer Charges start-up screen and that's it. When connected to a PC saw it as m3-chip.
In total, I found drivers in Device Manager I did update the driver for the M3-chip and now the tablet is listed in my device manager as libusb- win 32 device. I found a program that detects such a connected tablet. The program is Amlogic Image Burning Tool v.1.6.2.2. For the time being this my progress stopped. I was trying to upload with this software firmware downloaded from the manufacturer's website dedicated for this device, but I get the message "find no upgrade" and do not know what to do. Can someone help me ??? I'm not an expert, and the above step I got reading the various forums. To my eye it looks as if they fell bootloader, but thanks to the above program to see the tablet (or rather its processor) and now combines where to download a bootloader to throw it out there and then be able to upload the system such as the sd card. Or is there some other program or a way to restore the dead to life my tablet ??? Can you help ???
1. Turn off the tablet (hold the power button and count to 12
2. Insert prepared SD card https://yadi.sk/d/_6VITNSbhKPyi
3. Press and hold the "Vol +", press "Power ON" for 2 sec.
4. Release all buttons and wait for boot TWRP (about 10 seconds)
5. In TWRP select Install -> update.zip
6. Reboot tablet

[Q] Sansui Etab 801 Cortex A8 Problem

Update: I just got the original firmware sent via customer service.. but do not know if it would work or not.. Just updating..I'm scared cuz the firmware I flashed it with was for a Cortex A9 device.
I have a Sansui Etab 801 Cortex A8 Android Tablet. It got stuck in boot loop and after trying several firmwares which didnt work, kept asking for uImage_recovery, uImage, u-boot-aml-ucl.bin, factory_update_param.aml etc file. After some search I came across a ROM, for Ramos tablet, I used it cuz it has the uImage_recovery, uImage, u-boot-aml-ucl.bin, factory_update_param.aml files etc. When I inserted it into the TF card and did an upgrade, the device would not start up at all. Just some lights on the controls.
When I insert into PC, it recognizes it as M3-chip, I found out about the AML flashing tool..I am stuck at "write data to ram failed" and I guess it is because of usb_spl.bin. Is there a way to create a separate usb_spl.bin for my device or it IS IT THE SAME FOR ALL TABLETS?
If it is the same for all device, thats a problem as I'm just stuck at write data to ram failed.
HELP!
I found out that the firmware I flashed it with was for a Cortex A9 device...
