Hi, I can't recover my device after trying to update with another room. I will appreciate help to identify it and recover it. Decided to ask in this forum because of another thread about an S905XQ4 that was recovered. Here are all the details in order.
What I know about this Android TV Box:
- Sold as Radioshack 4K Android 6.0. This is the picture [link]. I opened/removed disipator and thermal paste to identify.
- Specs SOLD as having 8G of space and 1G of RAM
- Chip/ processor says Amlogic S905X Quad Core // J-TPS111 00 // B0DCOCN03210
- 2 Additional chips identified as Kingston C703U2338.05 & D2516JC4BXGJD each ONE, meaning each chip has those printed letters. Found here on Kingston website and the PDF says it's 4G of DDR3/3L/RAM, I guess those chips are actually the internal space (4g+4g=8G?).
- One additional chip (memory? with #1503251 G/01/A/987 and small letters KLM8G/GEME HSFL54AGP (appears to be eMMC samsung chip)
- Can't see any other relevant chip except from network, realtek wifi, etc.
- Important: seems I can't trust the specs. I found on some forums cases where developers found the custom rom of the device to be lying about the Ram Memory, I'm not sure if this is the case with mine.
- Checking the details inside the booted device reported p212/p213
Details obtained on a backup log:
ro.build.description=q200-user 6.0.1 MHC19J 20161105 test-keys
I searched the web for firmwares for 905X / T5KP / T95KPRO and roms marked as MHC19J, no luck so far. I'm using Amlogic USB burning tool, 4% is as far as I've been able to reach, I get switch identify error. I haven't found any web reference about a device that looks exactly like mine, not on the outside or the inside. I have searched for Android TV Boxes to see if I can get a picture match, also searched for boards, still no luck. I have no idea were this device was built, it's not popular so it seems. I have tried so far at least 25 roms marked with any or all of the key data posted here.
How did this got bricked?
Found the website atvexperience [.] com and found there were firmwares for the S905X so I wanted to try updating the box. I didn't use the USB Burning tool to upgrade, installed it? yes, did it detect my device? yes, but as explained I didn't use this for the firmware update, instead I used the SD card method. Used the reset button found inside of the TV Box and booted from SD, first rom didn't work and what I got was an Android logo with an X. So I tried another rom from the same website. That didn't go well, the device turned on, blinked and that's it, done and bricked. Since then I have no video, no lights on, etc etc. The power brick works, and even bricked I can connect it to my PC and use the Amlogic USB Burning tool, the device is detected, but I can't find the right rom.
Tried the Amlogic Burning Tool? yes. I have tried over 25+ diff firmwares that have identifications of working with the S905X but no luck. I'm using the mal e to mal e cable, the Amlogic Burning Tool does identifies the device but get stuck. In some cases I get stuck at 1% and get the "low power error", in other cases I get to 4% and get diff errors like switch identify error. Anyway I can't pass 4%.
Did I make a backup before creating this mess? YES!. I took my time trying diff TRWP, prepared the SD card and tried to boot. I didn't stop until I found the right one and yes I could boot from SD card using the reset button and use the graphical interface. I created a backup. Also tried modding the settings on my tv box AND THEN restoring the backup and booting the device again just to check if the backup worked perfectly, it did. So yes I have a TRWP working backup. The problem? after briking the device I can't boot from SD or use the TRWP tool to restore the backup.
I have tried at least 15 firmwares. Searched all over the web and found some broken links and some working links. At this point no luck yet. I've been reading about the "errors" from the USB Burning tool and to my understanding those happen because I don't have the right firmware.
It's frustrating having a TRWP backup that I can't flash because I can't boot into recovery. I can only identify the device via Amlogic USB Burning tool. Read about converting the TRWP backups to flasheable images but it only works on .zip files and I need to get an .img file to work with the Amlogic USB burning tool. If I could just recover the boot to get into TRWP. As explained the device is identified on Amlogic USB burning tool but I get no leds on (both leds are off).
JTAG? serial? yes. The device has the four pins, but the 2 extreme pins show 3V. I have no TTL device to access this, I do have an arduino but it's 5V so I would have to build something else to use the arduino as TTL converter
I'm about to trow this brick to the trashcan. Due to failing after trying the ATV Experience Rom (and got bricked) I did asked the guys over there. They are unable to identify my device and also guess it's bogus, not real specs. After my attempts I guess I've been confirming the device is not what it's been promised to be.
