Q8 (or vsmart Q8) RK3288 – Everything that we know
Some info that's not mentioned and might be useful:
RAM: DDR2LP @ 400 Mhz (x 2) -> Doesn't like overclocking at all! -> need to do more testing.
GPU: 500 Mhz -> tried OC to 625 Mhz, seems to work but needs higher RAM bandwidth for efficiency, need to do more testing.
ARM: 1800 Mhz -> No OC tried yet, overclock-o-matic fails to find the second kernel lock for some reason, don't feel like flashing new ROM/kernel just yet.
Wifi: AP6330
Referring to my box (ENY-Q8P-V10)... had some problem with the default update process (with W10 and XP).
Here's the problem and how I "fixed" it:
First of all I fetched Android Tool 2.3 from this forum, complete with the Rockchip driver (the unsigned one: had to disable driver signature check as adverted in W10).
Problem is: there was a "Code 10" error with device detection, meaning that every time I put the Q8 in "update mode" a yellow "?" appears in the device tree and the device isn't detected in AndroidTool.
There's no way to fix it (at least, I wasn't able to fix it) but you can go to device tree and "update driver" with THE SAME driver on the fly, then the device is detected as working and you can "use" it until the next device reboot.
A problem arise when you try to flash a new firmware (in my case Wasser4) because just before writing the device must be rebooted and the infamous "Code 10" happens.
For this reason (since you have a limited time span) keep your device tree open nearby, wait for the reset and "update" the driver as fast as you can, if you're fast enough you'll be able to do this before AndroidTool goes to timeout.
Add: This is my board, a "standard" ENY-Q8P-V10 but with a different sticker and a white code on the lower left angle.
The CPU "head" (heat spreader) is also different from the one in OP.
Recovery mode is as follows:
Additional rant: memory is "16Gbit LPDDR2 1066MHz 220-FBGA - K3PE0E000A-XGC2"

RAM needs to run at 533Mhz to play 4K videos smoothly, possible on all other RK3288 tv boxes with decent heatsinks.
4) Brick
If your device don’t have any signal of life, and can’t even enter on upgrade mode, well, the device is bricked. It’s time for desperate measures.
Disassemble your device, and look for the FORSEE chip
locate the 7 & 8 connectors. But the problem is: which corner start counting? Well, most of the cases is in the black arrow, but there was a time that I had to pin the yellow arrow! So, just start the procedure bellow with the black, if doesn’t work, restart and go to the others corners…
1. Open the RKbatchTool
2. Unplug the power supply
3. Plug the OTG USB cable in the micro usb port and in the pc.
4. With a screwdriver, PIN the 7 & 8 connectors
5. Connect the power cable.
The BatchTool should now show an blue device flag instead of the green. If is blue you can simply flash your stock rom again
Hi.
My TV box, I: XT-V10 2014-09-02 Q8L C Q8L label with 8G / 2G ST XT201410154
Brick was. I did it on the basis of section 4 but does not boot into the system.
A year ago, the same way I did the first time and managed to revive.
The LED lights up blue.
After the flash recovery writes:
E: clone_data_if_exist-> partition scanning error
Formatting / data ...
Formatting / cache ..
REBOOTING ...
but nothing happens.
I tried a hard reset. Nothing.
Firmware is Stock
Hi, I'm trying to revive my old Q8L, looking for firmware rk3288-eng 4.4.2 KOT49H eng.yangfeihu.20150625.111516 , MEGA ling does not work anymore, and I can't download it from Baidu.
Can anyone point me to this firmware (or even better send it to me via forum or email) please ?
