M97 does not boot, cannot recover

M97 does not boot, cannot recover
Hello,

My M97 tablet boots only to a little word Android and then it hangs.
I can start the recovery menu, but then I can not move to wipe data/factory reset.
When I use the volume button one just reboots and the does nothing.
   

Also it says:
E:Can't mount CACHE: recovery/command
E:Can't mount Cache: recovery/log
E:Can't open Cache: recovery/log
   

I installed GPG Android Tool By GPGIndustries but it says it can not read directories when I clik on check hardware / software.

All I further have on information on my tablet is:
On the back it says: qTab Mi97
On a one page M97 User Guide:
Android 2.2/2,3
Freescale iMX.515 800MHz ARM Cortex A8
4-side G-sensor
1024-by768 pixel resolution
some other info but I think useless for this problem

I bought it online here and know it is a Chinese tablet.
It worked like a charm until it "crashed".

Could you please help me out on this?

Thanks!

RE: M97 does not boot, cannot recover
Hi Ankur,

I opened the tablet.

On the motherboard itself I found this printed:
PAD1051M_V4
AZM

Then there is a "big" black 'thing' which has printed on it:
MCIMX5150JMBC
M77X
CTEA1034A
CHINA

I decided to add a picture:

   

All I further have on this tablet is in my first post.
Thank you!

RE: M97 does not boot, cannot recover
Thanks Naveen,

I see there are years of 2013 in the file names. So I wil try the oldest one because my tablet is from 2011 or so.

The 6 steps in the manual seem rather weird to me but I will try nevertheless.

I will report my findings.

Thanks Ankur.

I will first try Naveem's solution. Hope I can try yours if that does not work.
I will have to ask you for the steps though. I will let you know when needed.

Well Naveem, it seems it will not work.

First I connected the device to the PC. Powered it on and started Phoenix.

Then on the first screen it says:
See picture
Then I go to firmware and choose upgrade. Then it reboots my tablet and returns to the first screen.
Then I click firmware again. Then the message "There is no device to be upgraded" appears and after "Ok" the screen with the 6 steps shows up: 6 steps
When I perform those 6 steps it also ends with: There is no device to be upgraded.

So it seems connecting to the part of the device where the files should be written to fails.

RE: M97 does not boot, cannot recover
That is exactly what I did. These steps are in the manual of the downloadpage. But, to my regrets it did not work.

Thanks for helping!

RE: M97 does not boot, cannot recover
Actually, the “E: Can’t mount /sdcard/” issue is closely related to the file system type of your SD card and the inability of the device recovery system to read a particular file system.

Pull out your phone’s SD card.
Put in a memory card reader and plug it into the computer.
Create a backup of the contents of the memory card on your computer.
Now open My Computer and right-click the drive that shows represents your memory card.
Select Format… option.
Click File system and select NTFS or exFAT or FAT32.

You can download the SD Card formatter

Then click Start button.
Now copy the backed up files back to the SD card.
Insert the card into the device, boot into recovery to check if the problem is fixed.
In case the SD card issue mount issue is not fixed, try formatting the memory card again with a different file system (those you did not try yet). If formatting the card using the NTFS or exFAT or FAT32 file systems does not work for you, try [url=Then click Start button.
Now copy the backed up files back to the SD card.
Insert the card into the device, boot into recovery to check if the problem is fixed.
In case the SD card issue mount issue is not fixed, try formatting the memory card again with a different file system (those you did not try yet). If formatting the card using the NTFS or exFAT or FAT32 file systems does not work for you, try SD Formatter tool

It really work
