Hi,
I've got a Point of View POV Mobii 7 Bussinessline PROtab2 ( TAB-7C-4GW-1 ) which is stuck on the bootscreen.
- it does not power off when I press "power" for >10s
- the reset switch on the back powers it off
- pressing "home" while powering on results in an update screen after ~5s (little green android with box and arrow next to it) which changes to recovery ~1s later (android with exclamation mark) where recovery menu can be entered/hidden by pressing "home"
- wipe cache or factory reset in recovery didn't help
- "reboot system now" in recovery actually powers device off
I've downloaded the latest firmware from http://81.21.136.56/downloads/Tablets/ 7 Inch Tablets/TAB-7C-4GW-1 Firmware Upgrade/ which I was able to flash few years ago...
I've installed Telechips VTC driver which is part of the download.
Connecting the device via USB results in four "Telechip s, Inc.M801_88 USB Device" beeing recognized by windows as mass storage (empty drives) and an unknown device "M801_88" where no driver can be found.
It is the same in recovery mode and after regular boot. A usb reconnect is done when the device switches from update to recovery mode, but device constellation keeps the same.
Telechips Update-Tool "FWDN V7" (also part of the download) does not see a device (it should show a popup when a device connects, I guess)...
I've tried manually assigning the VTC driver to the unknown device, but that doesn't work. The driver supplied is just an installer... I found inf-files on the system after installing it, but assigning them says that they aren't drivers. Also listing all systems drivers doesn't who a driver from Telechip to select...
I've tried it on Windows 10 and in a Windows XP VM with identical results...
Any ideas what to do?
Edit: I managed to assign a generic ADB driver to the unknown device. It lists as "0123456789ABCDEF device" and limited shell is available (recovery?)
The device is okay again. I really hate it when things aren't reproducible, but after performing a factory reset in the recovery once again, it booted just fine...

Hello,
I've tried updating the Odys Genesis to the custom firmware cyanogenMod7 custom rom for odys genesis.
I think i did it the wrong way. I've searched for hours on the internet how to do it, and then i cam across a post that said i just needed to put it on the device and then android would pop up and say: "A new update is available" and i just would have to tap that. So, i did.
The device rebooted and started updating all kinds of stuff in a dos-like enviroment. But now it's only a black screen and saying ANDROID in white letters. I've kept it like that for an hour, and then i tried resetting it (behind the device, hard reset button). I see the Odys brand screen, but then it's back at the black screen with android on it again.
Is there any hope left? Can i do something to fix it?
I've tried searching for hours on the internet, and i came up with absolutly nothing. Any help would be greatly appreciated!
Thanks in advance!
I found out a little bit more:
- My problem is called a boot-loop. It seems like it anyway, i only see a tiny white text saying 'android'.
- I can't find anywhere on the internet if there's a recovery mode for the Odys Genesis.
- The device will turn on with any button-combination, except when i press menu+power or power+reset.
I have been looking at Odin, cause that should be a unbrick-program for android phones. But it seems you need specific firmware for your model. Can i just use the original firmware update from the website of the manufacturer?
Or am i just totally ****ed? Just a reaction alone would be appreciated !
Solution
And somebody can close this topic!
I'm extremely happy, cause by a little accident i discovered how i could flash back to the normal firmware.
For somebody who has the same problem, here my solution:
When the device is on the screen only saying android do the following:
- Press the hard reset button (on the back, the tiny hole) and the menu button at the same time.
- The android screen should now go away, and it should like the device is off (although it isn't).
- Plug in the usb cable and connect it to your pc.
- If you had your device previously plugged in to your pc before, the pc will falsly recognize it as 2 hdd's while there isn't any shown in this computer.
To fix that:
- Go to device manager (This computer (right click) -> properties -> device manager)
- Uninstall the falsly drivers, (so there is no driver anymore).
- Disconnect the usb cable and connect it again.
- Windows should now say (or say in device manager) that an unknown device is connected.
- Download the Pc Update Tool and original firmware from the manufacturer website: (can't post url's here, so google Odys Genesis and you will get there)
- At the driver installation window choose you would like to point where the drivers are.
- Choose the dir from the pc update tool, and choose the driver map according to your processor and windows.
- The device should now be installed as a RK2.... something device.
- Start the Pc Update Tool
- The first box below should be green, indicating it sees the device and is ready to flash.
- At the box image, choose the original image downloaded from Odys website.
- Click Upgrade.
All should work well now, the box (log) should keep you informed. It could take a little while.
When it's done, it will tell you in the window. The device should now restart and Boot recovery should start and the device, formatting everything, resetting again and then installing everything. It all could take some while, so be patient.
And that's it.... then everything is working again ! ~!
Please let me know where you downloaded the CM7 ROM from... can't get it from the link in other post
Thanks

I have the same issue, but I have a 64bit Win7 and it just won't work. Windows will not install the original drivers. Any other way to go around it?
I only need make a hard reset, any help??? I don't remember unlock code
I've tried to download original firmware but i can't find it.
I was using Gingerbread 2.3.4 and enter the Software Update option on the Settings Menu.
There was a Software Update available and started downloading, then it began to install, until it was finished. After rebooting itself, the initial "Samsung Galaxy SII GT-I9100" screen appears (since is rooted, appears with the Warning signal also) and it won't go beyond that screen.
I tried Recovery Mode, Wipe cache, Wipe Data/Factory Settings, etc, and it won't go further.
I download Heimdall, detects the device, but when it tries to connect, it says that there was an error "Claiming Interface Failed!". I search for an error like this one, and turns out the USB Debugging has to be ON in order to access the device when connected to the USB port.
Since I cannot get by the initial screen, I cannot set ON the USB Debugging option.
Is there a way to enable this from a Terminal or Command window? I am using Mac OS X.
Any help? I searched the website without any luck.
Thanks a lot!
Hi,
I have on my tf201 latest official firmware, 4.1.1 build-number: JRO03C.WW_epad-10.4.2.18-20121122.
As Asus doesn't provide any more updates for our device and mine is out of warranty I'm finally ready to move on to some custom roms.
My tablet is Rooted.
Now after a lot of reading I thought it would be wise to do a backup of everything and make my device unbrickable.
I started to follow the instructions on this site : matthill.eu/android/transformer-prime-tf201-jellybean-nvflash
At first I backed everything up with Titanium Backup and then I did a factory reinstall, so I would have a clean tablet to start.
Then I installed the unlocking tool and succesfully unlocked my device.
I restarted my tf201 with holding the volume button down to get the options to enter fastboot.
When I got to the selection menu, I press the volume button a few times to select the USB-icon.
Then I press the volume up button to enter fastboot, but nothing happens. It just freeze.
The only thing I can do is hold the power button until my tablet restarts.
Also, since i'm on JB I never could connect it on my pc anymore. It even doesn't show up as an unknown device.
So when I want to use ADB I have to use ADB Konnect (wireless ADB).

When you press up on the USB icon and it freezes that it normal.. This is fastboot mode.
You now must access it over a PC after installing the naked drivers.. If it is not showing on your PC then either try a different PC or your cable is faulty.
Thanks for the quick reply.
I tried once more to enter fastboot. Same result.
But when I disconnected my usb cable to connect it to an other computer, suddenly I got this message on my tablet:
"Starting Fastboot USB download protocol"
This message didn't show up before.
I plugged the tablet back to my pc, but still no device detection in device manager, even when refreshing (So I can't install naked drivers, as it is not recognized).
My computer is a Windows 8.1 system.
I restarted my tablet again, (after disconnecting it from my pc) and followed the procedure to enter Fastboot again.
I waited for the message "Starting Fastboot ..." and then I connected the cable to my other pc (Windows 7 system)
Same result as on the Windows 8.1 machine, not recognized
You say it could be that my cable is broken. Maybe, but it's a strange coincidence that this happened when switching from ICS to JB.
I know JB for the tf201 is been out a long time, and I updated since I could. So over time, maybe my cable could be broken now. But I'm sure I had this problem (not recognizing) since then, because right after updating I wanted to do some things with ADB and so I found out I had this problem.
After month of search and trial I had to start this thread.
Device Samsung Tab 4 (mother board ET-86V2G-A23-V1.2, A23 processor, china junk)
Problem: I tried to restart the device into recovery mode out of Clockwork. It never reached recovery just shows the logo SAMSUNg Galaxy ab 7 and that where it ended.
Restart into recovery with power and volume button does not work. I tried all combinations 10 times. The device does not have a hard home button.
Conneting to the PC via USB does not work. First is was not set for USB debaging and the PC does not even react when connected (therefore even drivers are useless).
All the advise I get is start in recovery or connect to adb but none of it works as explained above.
Does anyone has an suggestion how to reach into the bowels of the device without revoery and adb (USB connetcion)?
Thanks
Hi everyone, i ask for your help cause i have a common problem but the fixes i found in the forum didn't work for me: my ZenFone 5 stucks at "Asus" logo with a "loading loop" wheel below that.
I know this post may be long but i beg you to read all steps:
1) Phone stucks at logo, but could enter recovery (pressing vol + down), i've updated it via external SD card (official firmware but didn't work) then i've wiped data and did a factory reset. Phone still stucks at logo.
2) Now i can't even enter recovery mode... when pressing vol + down it shows 2 options but whatever i choose the phone reboots. If i press vol + up it says "CSC mode, long press power to restart. Phone still stucks.
3) Now (after some time) the phone's screen doesn't show anything, nor charging icon or notification led when recharging, but strangely the computer recognizes it as a device when connected via USB cable, and the led turns on when i do this.
A friend told me to follow a guide that says to install "Intel Soc USB driver", i did that. After installing, when connecting the device, 2 things should pop up in Device Mangager under "Intel Soc": CloverviewPlus Device and Intel Soc USB Driver... but the second one doesn't show to me
I've also tried Asus flashtool guide... at step 4 it says to click in the box icon and choose the firmware RAW file, so i've downloaded a raw firmware for the ZenFone 5, but oddly it doesn't let me choose any raw file.
Note: the phone is recognized by the pc as "QHSUSB_BULK", so i've tried to update its driver with qualcomm drivers, and now it's recognized as "Qualcom MMC Usb storage device". But i think i've did a wrong thing cause my friend told me i should have choosed some kind of official driver
Thanks in advance for your help
