I bought a piece Android tablets. Android 2.1 was installed.

I saw that was a little slow for Android 2.1.
I searched the internet a bit.
Adroid 2.2 and 2.3 is faster than writing.

So I downloaded the files from the internet UPDATE.ZIP.
I tried to install the error took off.
ANDROID MARKET trying to install has been deleted.
Then I searched some more.

I saw on the Internet is different from other menus I've seen androids recovery.
There ClockMod Recovery.
I downloaded the installation files from the internet ClockMod Recovery.
I tried to install the error took off.
Recovery mode is broken.

I searched the Internet a little more
I found Telechip Frimware FWDN program.
I set my computer to download.
2.1.3 software required for FWDN (lk.rom, NANDfai and tcc8900_mtn.img) files are downloaded.
FWDN program 'Vtcdrv' I've installed the driver.

I pressed the Menu button at the top of the Tablet PC long.
I put the USB cable.
FWDN NAND memory of the Tablet PC came with the program.
First, I received a copy of the NAND memory.
Then I tried to upload the files I downloaded from the internet.
I tried to install the error took off.

Forum Telechip several different sites (lk.rom, NANDfai and tcc8900_mtn.img) files are downloaded and installed.
However, the error took off.
FWDN received a copy of the original image of the program tried to install.
Now, there it was another problem.
Hold down the Menu button, and USB I wear
However, Did he a tablet PC does not see any FWDN.

Tablet PC, only the 'Android Sooner Single ADB Interface "sees this as

FWDN the Tablet PC does not detect.
But the computer detects the Tablet PC as Android.

Computer ADB driver perceives
In fact, 'vtcdrv' driver needs to detect.

Normally, the Tablet PC is detected in this way can install android.
ADB can not use commands. (I'm writing a shell ADB - Unknown devices and writes)

Only 'fastboot' commands would apply.
With fastboot (boot.img-recovery.img, system.img) installed... .

There is a changing thing.
Only shows a white screen ...:mad::mad::mad::mad::(:(:(

Searching the internet I met the following examples.

  • Menu + Power -> USB Connect ( I've tried at least 8 times )
  • Menu + Home + Power -> USB Connect ( I've tried at least 5 times )
  • Menu + Home + Back + power -> Connect. ( I've tried at least 5 times )
  • Power + Menu -> USB Connect ( I've tried at least 5 times )
  • Menu -> USB Connect ( I've tried at least 10 times )
  • Home -> USB Connect ( I've tried at least 3 times )
  • Back -> USB Connect ( I've tried at least 3 times )
  • Home + Back -> USB Connect ( I've tried at least 2 times )
  • Menu + Back -> USB Connect ( I've tried at least 2 times )

I think our way
I need to delete the NAND FLASH ROM memory installed on the Android.
NAND FLASH ROM is deleted, not in the Android
'Sooner Android Single ADB Interface "will not detect the form.
Because of - not the Android operating system.

I've tried different USB cables.
Put on different computers.

Nothing changed.

Look like an X6 to me:
And forget about recovery mode now.

X6

Latest official ROM: #387

Features
- G-sensor
- HDMI
- better touchscreen (new resistive technology)
- only 1x miniUSB
- microSDHC cards
- 1300mAh 7.4V battery
- 256MB RAM

Can you confirm specs?
If this is the one open the tablet carrefully and you should have a switch inside on the board(please confirm)

If this is the case:
Do not connect tablet to PC yet.
Download FWD 387
fire up fwd
load 387 (2 or 3 files) and add these files
change the switch on the tablet
connect tablet to PC
FWD should start restoring 387
when finish change the switch to normal position
disconect from PC and you should be back on after reboot

If you have the switch on the board there is praticaly no way to brick the device, if you have no switch on the board send a picture of the board as you'll need to make a small bridge.But I think the X6 has the switch.

Pictures actually indicate that this is a Phecda P7, not a HSG X6. The button placement is how you tell.

Sounds like you flashed the wrong firmware.

Not sure if this is the same as what you would want: http://www.filestube.com/925fkp5gJhrtFLfqerFBvR/phecda-P7-rom20101022.html

There might also be a 1103 firmware floating around somewhere.

There is supposedly a P7S as well.

According to this, there are two versions of the P7. One has Hyundai flash memory. This is another link to check:
http://www.99pad.com/thread-1505-1-1.html

1022 should be the last version for old flash memory.

I don't have time to fetch the other link. You should be able to find that somewhere.

I don't want to hijack this thread bit I think I am having a similar problem with my P7 but I cannot find the other firmware for my version of the P7. I have tried numerous sourses and it always ends with the FWDN status box getting to the check crc message and hanging at the end. Any help would be greatly appreciated. Thanks.

Hi everyone,

********************************************

1) I opened the rear door.

2) The following electronic circuit, such as changes in the picture I did.
$3.jpg

3) I opened FWDN program. (*. ROM and *. imgadded to the program.)

4) PC and the Tablet PC connected.

5) FWDN program has detected that the Tablet PC.
6) *. img *. rom and installed it. Installation is not finished completely. But the screenis no longer white. PHECEDA writes on the screen.

7) Then I brought into the electronic circuit and the old. So, I canceled the circuit made ​​to combine.

8) Then I closed device cover. Make sure the cables connecting the device alone.Cables with other pieces that will not damage the screen print making.

MTD area, write the complete

I have researched this site and XDA site. Yet I could not find a solution.

I wonder what I did?

The link won't let me download the file( P7 11/18 version) because of my IP address. Any ideas of where else I can find the file?

Thank you, it is very much appreciated!

it worked great. I will keep the file in case somebody else is looking for it. (There was a error unpacking it but I guess it was on a unimportant file)
