Hi,
First of all, great site you've got there, been checking it ever since I laid my hands on my first htc g1.
Secondly, and I hope I'm not double-posting about an issue already raised, as I've screened the threads quite thoroughly.
Here's the issue I have with my MK808B.
I've tried to start it with a USB ubuntu pendrive plugged into the USB OTG (I had saved some files I wanted to transfer, didn't realize it would mess things up).
Regular start up with this hdmi key is Google tv screen > android screen > home screen.
I get stuck at android screen, no matter how long I wait.
Out of nowhere, I tried to use another 2A power supply, as this had been advertised on other threads, no sucess... I also tried to start it with a paperclip pressing the reset button, didn't work...
Honestly, I don't know what to do exactly, I think it might have tried to boot ubuntu out of the usb stick...
I think I have no option left but to flash it (thus losing all that is installed already on it).
Is there any trick that could restore things the way they were? Any suggestion welcome.
Thanks for your time and help.
Solved by flashing
Hi,
Since no mgic trick happened to save the day, I was left with no choice but to flash it.
Used rockchip batch tools, crossed my finger so the stick wasn't a clone with the mediatek chip, flashed stock plus goodies rom, waited 10-15 minutes, and voila!
good as new, got rid of the chinese apps I couldn't even log on, but got a full wipe of my data.
Hello,
My Pioneer R1 tablet the other night decided to do an automatic upgrade when booting up and hung for hours on 14 of 18 files updated. I rebooted the tablet for it to get to the home screen but come up with the error android phone services not initinalized and then froze. so rebooted and it got to the animated pioneer logo and just sits there never loading fully. Pioneer customer support sucks with helping and the tablet has a reset button on the back in a pin hole. I pressed that the tablet turns off. The tablet still stuck on animated logo.The tablet was running stock jellybean 4.2. The Pioneer people didnt want to do any troubleshooting. told me to send it to them to fix and that if they found anything wrong other than hardware issue i am liable for the charges on to of the shipping cost. I dont have money to just hand out to people who dont have a system setup for troubleshooting. Sorry for a long story but my question is is there anyone who can help me fix this issue.
Unfortunately I'm stuck with the same issue, tablet was running slow so I rebooted it, got hit with their "system breaking update"
Spent a better part of the day trying to find a way to reboot it into recovery mode and wipe user data/reinstall but so far no luck.
Fired off a email to support, tried calling but the wait time was 54mins last time I called.
Also there is a automated announcement while waiting for call time informing everyone that they "are aware of a problem with the tablet"
If I manage to get it into recovery and fix this I will let you know how
so after further testing :
holding reset for 30 seconds: fail
holding power for 10 seconds: fail
holding power for 1 min: fail
holding reset and then power:fail
power then reset:fail
opening case to disconnect battery; FAIL soldered to the board/battery wtf ?
pinhole on bottom of case between usb and power port doesnt sync up with a reboot option

ok well this was an counterproductive day
called Cs @ 1-800-421-1404
waited 45mins on a "20min" wait
talked to someone who informed me this was the wrong number to call for help with the tablet
called Cs @ 1-888-999-0987
"we are experiencing a high call volume at this time, leave your name # and model number and we will return your call before the end of the business day"
waited until 3pm and called again finally got to talk to someone and it was horrible
I was initially told to press the reset button on the back, when I informed them that was not the issue. I was told to email [email protected] and detail my problem, after around 10mins of this, I was put on hold where 3 different ppl picked up and re-asked my problem. Finally when I asked to speak with a supervisor I was told he wasn't there.
When I explained that this is not uncommon in tablet from time to time, ppl forget what they used as a lock code, or one of their children played with it and put a passcode on the device. I was informed that they cant give me any further information because pioneer hired them to field tech support questions and they aren't part of pioneer. The whole reason they cant just tell me how to boot the device into recovery is they dont know, you see pioneer failed to give them that crucial piece of information.
supervisor is supposed to be calling me back tomorrow so lets see what kind of bs this is.
more then likely I will be de-soldering the battery leads from the board to force it into recovery tomorrow afternoon/
only thing I've found out so far thru trial and error is :
power on ,hold power till first logo, press reset and hold. 3-5 seconds later screen flashes white once (either turning on or off)
tablet off, insert usb connected to pc, rapidly tap power and it will stay on the charging screen , pc then recognizes device as libusb-win32 device "Worldcup device"
still no recovery mode
ESI is actually responsible for the tablet as pioneer leased out their logo for the tablet.
This is why there is a ridiculous run around trying to get help from pioneer's cs reps,ESI got my problem sorted.
look for a stock rom dump soon.
so what files would be needed exactly....
so far I have :
aml_logo.img
boot.img
bootloader.img
cache.ext4.tar
data.ext4.tar
logo.img
recovery.img
and still have to copy over system.ext4.tar
packaged rom file!
ok so after following this thread :http://forum.xda-developers.com/showthread.php?t=2195858
I ended up with this Pioneer r1 stock rom , anyone who has a stuck pioneer want to try ?

I've been doing some searching myself, since I've got a soft-bricked R1 (Father-in-Law didn't want it any more), and from the looks of it, reflashing AML8726-based tablets is done via a rescue-SD card, or using a manufacturer produced USB burning tool:
http://www.slatedroid.com/topic/41478-how-to-unbrick-your-amlogic-aml8726-mx-series-tablet-v20/
So it appears that the tools are out there, but I haven't had any luck finding the device-specific files that will help.
I don't suppose you manged to find a way to contact ESI's technicians without going through the support number?
There is a recovery mode i unbricked mine just a few day ago need help finishing it it's very unstable

Could sort of get mine to boot...
My r1 crashed while watching a video and when I tried to restart it was stuck on this pioneer loading screen. I noticed if i let the battery run all the way out I could then get it to load up... but was greeted with dozens of error messages. This program has stopped this program has stopped. Every two seconds another error so trying to get on to google play for a scandisk app was pointless. I chose to restart and... back to Pioneer loading screen :/
Anyone ever locate a stock recovery flash for this tablet? TBT-7R1-P can be flashed via adb and ImageBurnTool. I have 2 tablets that 1, I do have CWM installed but need to connect a mouse to navigate (using a usb mouse plugged inthru an OTC cable) and nothing to restore since I'd wiped it.
Hello everyone. I’ve got a hizpo stereo that a friend of mine give me a few weeks back. The numbers on the side of the radio is ADY17009. It’s running Android 7.1.2. The problem I’m having with it is the screen is inverted. I’ve tried the reset button tried erasing everything no luck. I tried accessing developer mode pressing build number 7 times and it didn’t let me access it. Anyone know where I can get a copy of the stock firmware and operating system on this thing or can I upgrade it to the latest and hopefully it will fix the issue. I can’t sign up on hizpo website. Every time I try to I get a connection timed out error.
Anyone?

This is usually a symptom of a loose connection in the hardware(believe it or not, a good shake, tap or bump this way or that way has been known to solve this) or a symptom of the sensor needing to be recalibrated(also solved by shaking/bumping or even lightly dropping on a soft surface from about 12 inches, but doing it while the device is powered off)
Or, if the device still functions correctly, there are apps that can recalibrate the sensors for you.
As for finding the stock firmware...
If a Google search for:
"Return to stock (your model number)"
Is not finding anything, then it probably isn't available. These cheap, off brand devices usually do not get any software support of any kind from the manufacturers, they do not release the stock source or the stock firmware to the public.
If it came down to really needing to flash the device, you'd have to look for a firmware from a device that uses the exact same hardware as the device you own. That can be very difficult, it requires opening the device to look at the numbers on the hardware components, then using those to compare to other devices. If one of those devices is the same as yours and has a firmware available, you can use it.

hi guys,
i recently upgraded my mcu to the sound patched version. sound is much better, but now the dam head unit cold starts every time. when before it almost never did. any ideas? i have already, factory reset, wiped cache, loaded my old mcu settings(like recommended saving them before the mcu update.) but still the same..... i have tried 3 or 4 different MCU's all with the same result. i read there is an option in extra settings, but mine doesnt have any option there except "play music for usb/sd card on start" or something along those lines.
Any ideias? its really anoying, as backup camera only works 30-40 second after cold start....
ps: my first mcu was mtcd_gs_v2_23_1, its a px5 unit. running stock rom, android 6.0. xtrons for the bmw e90
any help greatly appreciated.
