As per the title, I have a client who wants this done to their generic chinese/yarvik tablet. It uses the Allwinner A10 cpu afaik. Due to my very limited experience in building kernels(where I believe the "option" to enable/disable this is)/roms + the lack of sources for the tablet(just getting into fastboot took a while).

My phone( HTC Explorer /Pico A310) wont completely boot unless power cable is plugged. Yesterday, my phone just restarted when I was doing nothing. Then it goes till white screen where HTC logo is displayed(before boot animation) and restarts. It goes on repeatedly.
If I remove my battery and reinsert it after some time, phone starts automatically(without pressing power button) and goes to boot loop. I can enter into HBOOT by holding volume down key but factory reset, recovery etc wont work.
When I insert my power cable, It starts as it should, everything is fine. If I remove it while phone is on, it just restarts and whole process repeats..
My phone is not rooted, its still in stock rom GB 2.3.3. Its still S-ON.
I tried factory reset by power cable plugged in, reset was successful but nothing worked.. problem still there..
ok this is what is wrong with the phone. about 2 days ago my phone acted weird it shut off but after a while it came back on. Then yesterday it did the same thing but it never came back on. the phone was fully charged and as i went to reach for my phone to wake it up it didnt do anything. I have tried the power and volume for 2 mins nothing. I have had it on the charger but all it does it is hot but no light. I have never rooted this phone and dont know what is wrong with it. I only had this phone for 1yr and 3 months. All my contacts, recipies, photos, ect are on it i even tried to see if i can contact it to the manager nothing.

I have a USB Keyboard plugged in, but if it's plugged in, I cannot use any other keyboard except physical one. I even try turning off USB Keyboard, but it won't turn off.
What to do?
Rooted Aria/Liberty won't turn on if it's plugged in (wall charger or USB). The orange charging light is on and the screen is lit but black. The menu buttons do not turn on. I have to remove the battery after unplugging it for it to turn on.
The phone is rooted and the problem is consistent no matter what ROM I use. I believe it is a problem with the bootloader, but I'm not very advanced with these things.
I rooted the phone with Unrevoked and whenever I boot into recovery mode it says "Revolutionary CWM v4.0.1.4."I know it's minor, but it is my mother's phone and every time I'm on the phone with her she complains about it.
My Dad is looking into buying my Asus TF101 off me to use as an in-car navigation and entertainment system.
One thing I would like to try and do for him is set up something that will turn the tablet off automatically after the car is turned off. The tablet will be permanently connected to the 12V cigarette lighter socket via car charger. I currently use Tasker to automate many things on my phone and the tablet, and any experience in using it to turn a device off say 10 minutes after the charging source is removed (car turned off).
Has anyone had this problem on their Evo? It seems to work if the phone is off the charger but when I charge it overnight and have it set to wake me up in the morning it doesn't go off. And I have downloaded a new alarm app and tested it off the charger and on it and it as well only works when the phone is off the charger.

She plugged hers in last night to charge and it turned off. We thought maybe because it was so warm from messing with it. Well, today it's turned off twice for no reason at all. Anyone else have this problem or have a recommendation? Everything seems ok on hers when we compare our two. Mine has yet to do this once?

View 1 Replies View RelatedI want to let Android OS to boot automatically when the charger connected (for HTC Magic) without pressing power button
I found this guide: Complete boot when charging
If your phone only gets one of those ugly battery symbols when a charger is connected to a powered off phone this is because the init process is interrupted by /system/bin/chargemon. That file is a binary ARM program, I replaced it with a simple script containing only a single line: echo skipping chargemon
The file was created and installed with the following steps:
Code:
echo "echo skipping chargemon" > chargemon.script
adb pull /system/bin/chargemon chargemon.backup
adb push chargemon.script /sqlite_stmt_journals
adb shell
[Code]....
When the command su is given above, it might have to be acknowledged in a dialog on the phone screen.
The final command reboot -p shuts down the phone. As the USB cable is still connected it will power on again, and if everything has gone fine the phone will complete its boot process without halting with any battery symbol.
But I can't find "chargemon" in System/bin
Hey guys I had a question wanted to know am I suppose to have some type of charging light when the phone is powered off and plugged into the wall charger? or does this only come on when the phone is fully charged?
View 3 Replies View RelatedI have never even heard of the make and no software comes with the device. It's a so called "Asteroid" tablet which will not get past the boot screen! it just gets stuck on the android logo with the dots going up and down the space ship. He said it worked for one day and then it broke. It does look very similar to the generic ones being sold on other websites and are just called "7 Inch Android 2.2OS Tablet with WiFi and Camera".

I just got a Arnova 10D G3 and it doesn't boot. All I get is the "Arnova" logo on a black screen. I bought it on a refurbished condition, it was a pretty good deal so I am ready to do any risky procedure to make it work since I don't have much to lose.
I downloaded the latest firmware from the official website but I am unable to use it because I can't access the recovery mode.
How can I make it boot?
I am now able to access the recovery mode (power + vol up) but the tablet keeps rebooting after loading this mode. I don't even have a menu.
I've bought an Android Tablet a few months ago, there was an update recently, and my tablet stopped working, it doesn't pass the boot image. I don't know which model is my tablet (chinese tablet i guess). I've taken some pictures of the tablet.

I've got a issue with my impression 9.7" tablet... It seems not to BOOT, I think I may have accidently left the file system READ only... I can gain shell access and see what's going on however I cannot get it to remount as read/write right before it turns off... Factory reset won't do anything either... Here's the logcat as much as I can get out of it...

I am currently trying to flash my new Sanei n10 tablet with CM10 and it is proving much more difficult than I first imagined.
My main problem seems to be that the device just does not want to boot in CWM. I have installed the latest version of CWM (found here) via the Terminal Emulator but it doesn't boot into CWM Recovery, but rather just boots normally. I have also tried using the hard keys to boot into it but all that does is boot me into the default android system recovery (3e) which is useless as it will only update from verified roms.
The device is rooted and I have ROM Manager installed. I have given Terminal Emulator superuser permissions... It just doesn't seem to want to boot into CWM Recovery. I have tried using both ROM Manager as well as NOVO7 Tools to boot into it but I get the same results (device just reboots normally)
I think that it might be something to do with the stock ICS 4.0.4 that came with the device.that is causing me so much hastle.
I've been trying to root my Nook Tablet to CM10 unsuccessfully. I found this [URL]..... which led me to believe that downgrading to the 1.4.0 update would be useful.
I followed the link from this, [URL] ..... and downloaded the .zip and put it on an mSD. I proceeded to place it in the tablet, turned it on, and the update went through and my screen went black. After a minute or so I hit the power on button, and nothing happened. Nothing works on it now. I've tried hitting the power button for 20+ seconds then the 2 seconds, as well as the power + N button. The screen remains black. I can connect the nook to my computer and the power cable lights up, as well as when it's placed on the wall.
The Nook Tablet (it's a BNTV250) isn't turning on.
Recently I have rooted my android tablet and I was exploring what I could do. One guy was telling me about an app that can work with performance in game(ChainFire 3D). He said it lowers the pixels in the game to run better. I tapped the install button and it said rebooting now. It then started to reboot but then proceeded to get stuck at the boot screen. I tried doing a hard reset but it is still stuck. I have also tried flashing the stock rom, but I get installation aborted when I try and install it.
View 4 Replies View RelatedI have a chinese Allwinner 7" tablet ( Rocky M713HD ) , I was trying install a CWM recovery image. I connected my tablet to PC, opened my terminal and taped:
adb push recovery.img /data/
adb shell "cat /data/recovery.img > /dev/block/nandg; sync"
adb shell "echo -n boot-recovery | busybox dd of=/dev/block/nandf count=1 conv=sync; sync; reboot"
After that, my tablet freezes on bootloader with no single info on adb when typing "adb devices"
As you can see, I missed a caracter on the 3rd line: ( nandg/nandf )
I was on Allwinner 4.2.2 ROM.
I have just bricked my tablet by puting another recovery.img.. and now the tablet only shows boot screen. How can i connect it to pc to usb adb to restore it...or another method?

I received a generic Chinese table. it worked well for about two-and-a-half months. Then, just recently, I discovered rooting and the wonderful things it allowed you to do. I decided to download a system-tweak app, which included a CPU control. I was a little wary of overclocking my CPU, having heard it may decrease its life expectancy, but finally I thought "What the heck?" and in a brilliant stroke of genius cranked my 1Ghz processor up to 1.5Ghz, and it promptly froze, forcing me to power it down. When I turned it back on, I discovered that it had been factory reset. I re-installed my apps, including the system-tweak app, and decided not to touch the CPU controls for a while. Soon after, while at my sister's talent show, I discovered I had about 30% battery life, and I was still supposed to record her. So I figured I'd underclock it to save the battery.
Unfortunately, as my finger touched the slider, my brother bumped my arm and caused me to lower the CPU frequency to its lowest setting. It became extremely sluggish, almost to the point of being unresponsive, and finally I had to shut it down. When I restarted it, it started to boot but then got stuck on the shimmering Android logo, and now that's all it does. I can't even boot into recovery mode, and unfortunately I had just turned off USB debugging that same day.
I have a problem with my chinatablet.
It's a X-Touch tablet X714 as the back case says and DFP7006.... anyway i don't mind what the heck it is.. problem is:
It's been working satisfactory for half an year and yesterday i installed BusyBox Pro, dsploit and Flappy Birds.apk from unknown sources... so than battery died (it dies in 3hrs) and today when i charged it up it booted to factory erased mode (cold or hard boot i guess you call). I didn't mind it at all, started installing apps from SD but there was not enough space, actually not even a bit of storage. Now every time i boot my tablet it keeps erasing. Strangely enough i found mojang folder in the mnt/sdcard/ directory which i could access with built in file explorer.... So tablet didnt actually erased everything, but rather just denied my permission to use them and any free internal memory..
When I turn my tablet on, I get a battery symbol with a triangle around it and exclamation mark in middle.
