Название: DR500GW-HD self bricked?
Отправлено: neoncek от 05 Ноября 2014, 13:57:48
Hello guys, greetings from Slovakia  ~))

I am dealing some problem with my DR500GW-HD already discussed at dashcamtalk forum, so I`ll copy-paste some info here as I am lost in ideas how to recover it.
Link to discussion:
http://goo.gl/Iz3RdE (https://car-dvr.info/forum/go.php?url=aHR0cDovL2dvby5nbC9JejNSZEU=)

Issue description:
Everything was ok untill yesterday, I stopped at the petrol station and once I moved, camera repeated some some non-english sound. I guess russian. Several times I removed power cord to restart, no success.
At home I removed card, used SDformat tool, made surface scan and copied them fresh-downloaded firmware v2.002. Same software version was on SD card before.
All LED blinked once, then GPS (blue) LED s ON for 6 seconds,
then Security LED (in front) & REC LED (in red) & WiFi LED blinked once,
REC LED (in green) keep ON for 11 seconds.
During this time there is no recording detected on microSD card.
Once started without SD card, same behavior as described above but green REC LED keeps ON untill powered.
I have tested 2 microSD cards fresh formated to FAT32:
- 16GB MicroSDHC from Pittasoft
- 64GB MicroSDXC Kingston
Car voltage checked, it gives me 11,89V DC, at home I use 12V/1,5A; 12V/5A and 12V/300mA power supplies.
Several monkey-snatch tried with reset and WiFi button, no success too.
Battery was changed 2 months ago, I have tried to install firmware v1.005E on SD card, but no success, it just ignore SDcard.
I guess I will need to use some UART cable..
Or is there any way for deeper troubleshooting?
I am open to all possible options to recover my only dashcam.
May I kindly ask you for guidance please?

Thank you in advance for your advices.

Hello, at the first --> thank you for reply  ;)

I have run my dashcam without SD --> no WiFi found, REC LED stayed green untill power off
I fresh formated my Pittasoft SD 16GB using SD formatter (FAT32 32kB), put to the cam switched on my power supply
 --> no WiFi found BUT I got a sound I heared in the car as described above

OK so, I need UART cable at the first. Would this be applicable?: http://goo.gl/1d8kBx (https://car-dvr.info/forum/go.php?url=aHR0cDovL2dvby5nbC8xZDhrQng=)
 ..--.. Is there any procedure/guide how to push the firmware there?

So if I want to push custom firmware from http://goo.gl/DRvKKG, (https://car-dvr.info/forum/go.php?url=aHR0cDovL2dvby5nbC9EUnZLS0cs) how to connect UART (pins) and which file to push to DR500GW-HD?

 )ooo( Great, thank you guys, Gtranslator gave me text in english so I can go on once I receive UART  )ooo(
Based on picture from Delorm`s first post of mentioned topic, I should connect to 16PIN slim connector.
Guess I can write down some steps in english afterwards...  |||

Hello guys,

I have just received UART and cannot wait so I connected cables, installed driver for UART, started dashcam without SD, holding "d" while I got a prompt:

Hello from Australia!

I also had my Blackvue self-brick, with it booting to the Korean "upgrade failed" error message. I think it bricked after the Blackvue was powered off whilst it was still originally booting up & it corrupted itself. (I only moved my car from driveway to garage)

Thanks to your instructions I've now fixed my dashcam!!! )ooo(

I had a little trouble with translations & following the instructions/process above, so below is the consolidated steps which fixed my unit...

1. Connect serial console to computer at 115200/8/N & no flow control.
2. Power on Blackvue, boot status should appear
3. Soon after powering on (or resetting), press the 'd' key to enter the boot loader config.
---Restore Root File System---
4. At the boot prompt type: loadb 0x82000000
5. Then immediately use your terminal program to KERMIT send the cramfsImage_DR500GW file from the BlackVue\System\upgrade folder within the firmware download ZIP. (I used Terra-Term, File Menu > Transfer > Send > Kermit command. It took hours!)
6. The terminal should then say that the transfer was OK
7. At the boot prompt type: nand erase 0xa00000 0xdd0000
8. Then to "write the file system of the NAND flash memory", type: nand write 0x82000000 0xa00000 0xdd0000

---Restore system software---
9. Copy patch_DR500GW.bin file to root of SD card & Reboot the Blackvue
10. Blackvue will boot up - and in my case still got stuck looping the korean 'upgrade failed' error message. Press CONTROL+C
11. Login as username = root & password = pt
12. Enter these commands... (I *think* this is what worked for me, I had some confusion with the original forum thread with these instructions; see http://car-dvr.info/forum/index.php?topic=801.0 (http://car-dvr.info/forum/index.php?topic=801.0) for clarification
# cd /
# mount -t vfat /dev/mmcblk0
# umount /mnt/nand
# /usr/sbin/flash_eraseall    /dev/mtd4
# mount  -t  yaffs2  /dev/mtdblock4  /mnt/nand
# tar -xvzf  /mnt/mmc/patch_DR500GW.bin -C /
# sync
# reboot
13. The Blackvue should then boot 'normally' again and reformat the SD card!

Hopefully that helps others out as I thought mine was dead until I found this info :D

Hi!

I have a similar problem with my camera.
I looks like the firmware is corrupted and it doesn't boot.
When I plug it in, all the LEDs light up, except the blue GPS LED, and all stay lit. No blinking.
When I unplug it, all goes out.
No voice messages.

In the link below, you can find a short film with the camera.
What do you think, is it software related or hardware?

I've tried re-installing the firmware with no result.
Also tried with another SD card and without any card. Nothing happened.

Would that UART interface help?

Thank you!

How can I use it to reprogram the camera?
Where do I have to connect it?

I see there is a 3 pin connector on one board and a ribbon connector on the other. Which is the right connector for reprogramming?

negon, What's wrong with your dashcam.

I think I bricked my DR550gw-2ch.
First i have ulgraded the FW to the latest korean FW 2.010. I have put the upload folder on the root directory of the sd card and upgrade cgi on the config folder. The blackvue changed to english but it says that the version information is different so I tried to return it back to 2.010 korean FW. It changed back to speaking korean and it seems that it is still saying that the version information is different. Hope that someone can help me.
