General :: Crypto Tablet (GRC) Based On TCC8803 800mhz Dead
Oct 18, 2012
I have a tab with following specs TCC8803 800mhz, 256ram, 4gb intern SD, display 7" 800x480 capacitive, HDMI, rtl8188cus wifi, no 3g. no bluetooth, no gps, support extern SD -32gb, support extern keyb thru USB-OTG.
tab was rooted worked ok till tried to put Linux through Internet. Was downloading packages and then wifi lost connection.ever since the chip warm-up ( opened tab and felt it ! ) but no display or sound at all !! I think i left it on debug mode in order to have external keyboard work.
windows 7 will see it as 'unknown/ unrecognized' device, i forced ADB drivers to it, I get Android phone but also 'device cannot start.
Tried to conx with TV via HDMI but nothing there too.
Tried to format a 4gb SD with sardu tested ok with quemu but nothing on the tab. no lights, no sound, silence of death !!! FYI no power led on this 150 euro device.
have saved some system files.
Android 2.3.1 Gingerbread, rooted with superclick 2.3.3.

I have a noname chinese made Rockchip 2918 based tablet PC that I am trying to root so I can use some tools to increase performance/etc.
I have ADB and the Android SDK installed.
I have the most recent Rockchip drivers installed.
I have Development Mode turned on on the tablet.
When I plug the device into USB, nothing happens other then the windows notification sound to let me know something was plugged in. No "searching for drivers" nothing. When I go to ADB and do a "ADB Shell" command, it says device not found.
If I boot the tablet into Recovery mode, connect USB, and repeat the above procedure, I get the same result.
Is there a seperate USB Recovery mode I need to get into? I read about this on other RK2918 based tablets and I have tried all the methods to no avail. Volume up and Power is the only combination that does something, and that just takes me into normal recovery mode.
Just a side note, If I connect my HTC Evo 4G LTE and try the shell command, it finds it instantly.

I reckon that I have deleted all the data from partitions such as boot, system, cache, etc all of them. Hence, the Nook tablet isn't starting into any mode except the recovery mode of ClockWorkMod. How to restore the boot entries of a Nook 16GB tablet?

now won't boot! I just see the fish and the bubbles but like in a 16 bits resolution, with colors all messed up, and doesn't do anything else (the screen looks like this one: [URL] ...). The whole procedure didn't report any issues but now I'm stuck with a "fail safe mode" or something like that.
I've been told that the problem is that I used a file (lk.rom) for 1024x600 instead of a 800x480 one, and I need to get correct ROM files for 800x480 model.
I tried with DX but they just avoid giving me what I need... So the bottom line is: I'm loooking for the original files of this item.
Here's what I know about the tablet:
MID TCC8803 Cortex A8 with android 2.3.3, somewhere in the user manual says LY-F521, and in the chinese part of that manual also says EM72/EM73, surrounded by characters that I don't understand.Has HDMI, Camera, capacitive touchscreen.

I cannot find any documentation that specifies the algorithms that I can specify in getInstance for Cipher. Is there any around? Specifically, I am looking for support for the RC4 cipher.

These benchmarks were taken with: Quadrant Standard
550 mhz Score: 351
800 mhz Score: 441
1000 mhz Score: 569
Thought that I share these incase someone was curious. I have a Android 2.1 Motorola Milestone. Its interesting to note that at 1000mhz when compared against the online database of benchmark results the Milestone placed higher than the Nexus 2.1. Though of course the nexus 2.2 still lead the charts.

I have a Nexus 7 tablet and every few days I notice a few new apps on the device. I'm not sure if they're full apps or just simply icons to download apps or get more information. I have tried to avoid using them. I know previously I had a couple apps that were sending notifications to the notification system that I considered to be spam. After some research I found out how you can find out which apps are doing it and disable notifications from those apps so that took care of that.

Does overclocking your droid to lets say 800mhz or 1000mhz overheat it? Or will it cause any damage to it?

My Samsung Galaxy S2's battery went dead because I didn't charge it when it was down! The first times I tried turning it on it turned on and off almost instantly once it had got to the lock. Now it just vibrates (does this when you turn on) and does nothing.

My Nexus 7's (2013) battery was low so I decided to charge it. I plugged it in to a AC adapter and it showed that it was charging. The tablet's battery was decreasing! I decided to turn it off and charge it. I've been trying to fix the tablet for a while. It showed empty battery icon, LED light above the usb port was flickering 5 times. Then it showed no more sign of life. I've tried many things including holding power button for 1 minute, tried different chargers, plugged in a different outlet, used original charger. The tablet is still under warranty but I don't want to go through all the trouble to get a new one. My tablet is not rooted.

Is there any way to control from outside an Android which screen has become nuts ?
I have a chinesse phone ( and MTK 6573) which touch screen has become nuts (most of it has become unresponsive and often a continuos touch imput is detected in the center-left side of the screen). So, it has become useless...
The thing is, I would like to access to it, in any way, to recover some of the data I have on it. Also, becouse I try to disasemble, volumen key seem not working. How could I connect to it ?
I tought of the mimobiler, but I need to enable it trought touch and hadn't been able I tought backing up and restoring in another mobile (an MTK6577), but volumen key not working for ColckWorkRecovery would be to control it from mouse or similar, in a way that does not affect the missfuncionality of the touch screen (should be disable I presume). But anything that allows me to recover the saved phones (several got stored in mobile instead of google account), and a couple of apps data (a fianace data and a notes app) would be great something like remote-titanium-backup ?

I've noticed with a lot of cleaning app's they leave behind unused folders and files of app's that have since been removered and started up a small graveyard so to speak of these app's and their directories...
Is there an app that will inspect your installed app's and then clean and free up space according to what's installed and what's uninstalled but left behind?

I bought the Thl W5 and he came with one white dead pixel and slower i expect.
To correct the problems i decided to flash the phone with the latest update from the THL website.
For my surprise the oficial ROM from the THL do not support the Brazilian Portuguese, only english and chinese.
Could backup and upload the international ROM that comes with my language?

I bought one Star N9500 from aliexpress and after few hours, it had the most strange thing I faced with a mtk cellphones because I tested many different chip and models but this one after I try to charge it because the low battery, when I come back I found it like power off, so I tried to switch on and the big surprise cannot switch on anymore. I did many tests like charging the battery with external charger,pressing both buttons volume + and power or volum - and power.... but nothing can make it wake up. The screen is black and no signal of life.
When I plug the cellphone, here is the most strange thing, I can hear the sound like a new device found but just after 2 secons again the sound of windows when you unplug a device and again like the first sound when u plug it, mean like u insert a pendrive and u remove it every 2 or 3 seconds but of course, the cellphone all the time conected by cable and testing different usb ports.

I recently ordered a Rikomagic MK802 II: Amazon.com: Rikomagic MK802 II New Generation Mini Android 4.0 PC Google TV Box HD IPTV Player: Electronics
I was intrigued by the concept of a mini PC and thought it could be a good way to get YouTube, remote potato, etc. on my non-smart tv. When I first got it I plugged it into the TV and plugged the USB into my laptop for power, it started right up and worked fine. I connected to my wifi, synced my Google account, and downloaded some apps. I also removed all the Chinese apps that came pre-installed on it..After awhile I powered it down with the "power off" option in the task bar. The next day, and several attempts after, I could not get it to boot back up. When I plug it in, it starts to boot and the Android screen comes up for awhile, then the screen flashes white and it starts over, and continues cycling like that until I pull the plug. I've tried USB power from my laptop, a powered USB hub, and a USB wall charger, all with the same result.
I don't feel comfortable sending it back to this manufacturer with my account synced to it. I've pushed the hard reset button inside the device with a pin while it was powered on, but I'm not sure it had an effect. I can see the device on my Google Play account, but can't see a way to remove it from there.
what I could try to get this device booted, or any steps I can take to remove it from my account without getting it booted. I suppose if I change my Google password, that would prompt all my devices (including this one) to re-enter the password next time it's booted?

My GNex took a baseball to the screen; the screen is shattered and unresponsive, but the phone will power on and I can see the file structure if I connect via USB to my PC. I've retrieved all the files and photos that I want to save from the phone by copying to the PC, but not the text messages. I had a backup for the text messages, but it's gone (different story for another time). So I've been searching for a way to retrieve these text messages that can be executed entirely from the PC side, since I have no way of installing an app on the phone. I'd either like to be able to copy the SMS database to a new phone via PC, or dump it into some sort of manageable text format.
From the searches I've done, it seems like I might be able to do this using some sort of developer's code; (i.e., Install this program, plug in the phone, enter these lines of code, etc.)
The phone is stock (not rooted), and was just recently updated to ICS 4.0.4 (?)
Samsung says they can "fix" the phone for $160+, but that they won't be able to save any of the data since the phone isn't navigable (I assume they'll just send a replacement).

I have a dead Nexus S 4g that won't power up anymore, tech guy at the phone store couldn't figure out why. I got a 2nd working Nexus S 4G afterwards. I want to move the pics from the old phone to the new phone but because the NS4g has NO external SD Card, and the hard drive in the old phone is soldered onto the motherboard, I don't want to remove the solder from the old board and put it onto the new phone, it sounds messy and a lot of work and I'm afraid to "screw" it up even more. I want to move the entire board onto the new phone and try to retreive the pics and then move it back. I don't know if this will work but I want to try it out anyway.
1 of the tiny screws from the new phone was stripped and I can't unscrew it to disassemble it ! I've been searching online and people generally have bigger screws to remove (on bigger hardware) but couldn't find much on tiny screws on a delicate electronics like our smartphones, thus posting here now. How to get the pics out.

People are still sending me texts even though I can't read them. I can still hear notification sounds. I've gotta get a replacement quick, but I also need to get the important texts I missed. Is there any way I can get them through my mac?
To be clear, the screen is completely blank but I can still unlock it via touch pattern. It takes a few tries but Android File Transfer on the mac will tell me if it can or can't connect. If it can't, I just try again and I can get it. So the touch part still works, it just doesn't show any information.
The phone is a Galaxy Nexus. When I connect it to my Mac, I can see the files in it via the Android File Transfer window. However, I can't find the texts here.
I have the Android SDK installed and I was told I can do this: adb pull /data/data/com.android.providers.telephony/databases/mmssms.db..However the device shows up as offline when I do adb devices. I can't figure out a way get it showing up as online without being able to use the screen.
