I am trying to use my cheap virtually unbrickable tablet to learn more about kernel development and eventually ROM building.
I have extracted the manufacturers (WoPad) LiveSuit image and used split_bootimg.pl to break up the boot image.
I extracted the config file from the kernel image using extract-ikconfig and it created a config file. I didn't see the config in /proc.
So, I have the factory ramdisk and the factory kernel config.
I have downloaded several kernel sources (lichee-3.0.8, ChritianTroy's 3.0.36, and another one from linux-sunxi 3.0.72). I can successfully compile all of them without errors and they all generate zImages, uImages, etc using the factory config as well as the sun4i_crane configs they come with.
When I repack the boot.img with the newly created kernel and install it on nandc it wont' boot past the android icon (u-boot). When I compare my boot.img to the factory one, they both have the same offset where the kernel starts (0x00000800). I have also ensured I'm replacing the kernel modules when I'm changing kernel versions.
Tablet hangs in Bootloop after installed cm9_nightly_20120721 + protab2xxl_compatibility_1.2.0 startet from cwm 184.108.40.206. Noticed that the "/data" partition only has 15MB of Space with 0B Byte free. I wiped the cache after installation with cwm, i am not able to boot to cwm again because key combinations not work on this device.
Got a T15A Generic tablet which has the same Hardware than protab 2 xxl, Goclever A103, Coby 1042 etc..how to get CM9 or CM10 running?
I own a Allwinner A13 7 inch tablet, on which I installed the Cyanogen 10 mod (Due to restrictions I cannot place the link to the mod)
The problem is I probably installed the wrong touchscreen driver, so the tablet boots perfectly into the Mod but I can't do anything. Normally it would be no problem to just put back my backup, but I can't get it to boot into CWM.
In the first place I rebooted into CWM to instal the mod by adding the following command through the "terminal app" before rebooting,
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 am thinking it might had hit "un-allocated" memory area, I did have to change the ramdisk_offset from 0x01300000 to 0x02000000 make the kernel fit. what could I do to check to see if it is un-allocated space I am dealing with
im new in android and a couple hours ago i try to instal beanstalk - legacy kitkat 4.4 and they suggest to download kernel from dark raven "dark kernel cm11.0" 11DarkUrushi20131130 after that im flash the kernel and something happen....
my phone dont boot up and the logo dont appear
im try to connect to flash tool but still dont get it...
I wanted to change the boot logo for i9300. Im well aware that you have to incorporate it in the kernel. I installed Ubuntu, the necessary libraries and brought the cyanogenmod source code. Only part is I dont have the necessary experience to tweak it using the NDK tools
I have a phone with a MT6577. The vendor (Wiko) published the kernel source code. So, i'm trying to build it. I can get the zImage. I converted it to boot.img but i can't boot with it on my phone.build a good zImage? (if you want to try) : URL...

I want to get a custum recovery because I can't access to my recovery mode it shows a foto of a droid, I tried rebooting from rom manager app, and from the power and Vol+ .. but nothing works you can check the foto in the attachments.
Is CWM available for the Eken T01? I have posted this question several times on other boards and never got an answer either way. I just got this tablet and I have rooted it. However I would really like to make backups with CWM like I do with my phone because it has saved my butt more than once
I recently acquired an A13 tablet and wanting to install CM10 on it I first installed CWM 220.127.116.11 according to the famous manual (if it's relevant I'll post the exact url). Anyway, it got stuck on CWM (doesn't boot normally). Now I figured it can't install since using 'adb shell' and looking at /proc/partitions -- nothing is there! """ cat /proc/partitions major minor #blocks name
- bought a Thomson QM734-8G tablet (Allwinner A13b clone), running Jellybean 4.2.2; - PC interface worked fine in MTP and large storage modes; - setup Android SDK & Java JDK on PC and communicate with tablet via ADB;
All OK so far..After a couple of days, I decided to replace stock recovery with ClockworkMod Recovery, so I could start messing about with the tablet.
I found the CWM 18.104.22.168 mod supposed to work with these tablets and, following instructions, determined it was indeed running on sun5i hardware and had 10 partitions (nandj) and downloaded the appropriate version.
I used ADB sideload to install CWM and everything appeared to work OK ... until I rebooted and found myself stuck in a never-ending cycle of CWM-based recovery bootloop.All I get is the CWM recovery console, with a few lines of error & the tablet will go no further.
E:can't mount /cache/recovery/command E:cant mount /cache/recovery/log E:cant open /cache/recovery/log E:cant mount /cache/recovery/last_log E:cant open /cache/recovery/last_log
CWM functions work properly and nothing will mount through the 'Mounts and Storage' section, although sideload mode still seems to work.Attempts to use ADB sideload to install a different CWM or other recovery image have all failed, and LiveSuit and PhoenixSuit both have issues detecting the tablet (despite trying various versions of each & following instructions precisely), so I can't flash a replacement ROM to fix things.
At the moment, I just want to rip CWM out and go back to factory recovery mode and have a working tablet again! I think the Bootloader is locked and the tablet is unrooted. Superuser or SuperSU don't want to install properly. However, using ADB, it looks like I can get root access in shell (#).
Basically I ran Livesuit to flash my Chinese Tab, its called a desiretab has an a10 processor. Anyways the first flash was successful, besides the fact that it didn't pick up touch calibration correctly. So, I decided to flash it again with a different firmware image, low and behold it gets about 50% in and just freezes up. Now the Tablet shows no form of screen output, I attempt to flash it repeatedly, nothing works.
When I say I attempt to re flash it and nothing works, I'm saying that it just sticks at zero and the flash command does nothing.
i have a allwinner a13 tablet that has gotten stuck in the process of opening. i had installed clockmodrecovery and uberizer. and was looking for a way to correct root 'permission" that kept coming up when trying to install programs that needed root access. then i messed up.
i was trying to restore factory when it froze. i cannot use buttons to enter recovery mode. i made a back up in uberizer but am unable to find .how to use. also since this is happened i cannot load any driver to recognize the tablet into windoes 7device manager.
I have a generic Allwinner A13 7" tablet essentially identical to this one. The internal memory is set so that part of it is seen as internal, and part as a fake SD card mounted on /mnt/sdcard. Actual SD cards get mounted to /mnt/extsd.
I find this very annoying for a number of reasons, and would like all the internal memory to be seen as internal with no fake SD cards, and SD cards to be mounted to /mnt/sdcard. If this were one of those tablets capable of running Linux I'd run gparted and do the job from there, but it isn't.
Is there any way to merge the two internal memory partitions into just one?
I'm aware I can edit vold.fstab and invert the two mount points, and I'll keep it as a fallback solution, but I hate the idea of wasting a gig of useful internal space like that.
I have an Allwinner A20 tv box, I trying to use it on a device with an old, low res, 4:3, 5" screen. It works but I have a few problems - firstly the box has "pal" and ntsc" settings for use with AV out, but when connected the picture is squashed inwards so circles are represented as ovals. I ve tried to mod the aspect ratio/resolution but nothing works, the picture is always distorted.
On top of that everything is too small for the screen, it is readable but things really need to appear bigger, so I also played about with the dpi, this does make things bigger and a better match for the screen, even though the device doesnt actually have a screen itself.
I ve done both these mods with several apps and modding the build prop and I always get "sorry systemGUI has stopped", constantly - when you close it, it opens again straight away. Clearly settings doesnt like these mods, so I m trying to work what I need to change so it DOES accept them.
How I can successfully mod the setting.db and get this working at the correct aspect ratio and a dpi that is suitable for use on a low res screen ?
I have an Allwinner A10 clone (Kurio 7), it is designed for kids but otherwise a standard android tablet. After hours of googling I rooted and installed CWM & Gapps (not included in the stock ROM). So far so good. The stock ROM was causing issues with some apps, it needed to go.
I flashed CM10 and it worked but no touch screen. It needed a compatibility flash to make it work. You can guess what's coming. I picked the wrong one and now the device does the following:
Reboot loop Black screen (backlight though) PWR+Vol up no longer gets to recovery Vibrates constantly between reboots (due to wrong patch I'm guessing)
ADB picks up the device for a split second between reboots but "adb reboot recovery" does nothing. Even when using wait command. Tried "fastboot flash recovery cwm.img" after wait command, no luck. Is there anything else I can try?
