[Android Q&A, Help & Troubleshooting] lemayautocare:
I just picked up two of these. Both lost touchscreen the first time they connected to wifi. The first started working again after playing with the reset pinhole The second one I couldnt get working. At this point I have CWM flashed through the regular recovery but it isnt working right. Keeps getting errors that the cache partition isnt accessible then when i reboot it reboots right back into cwm. Anyone got any ideas of what to do here?
[Android Q&A, Help & Troubleshooting] mthous01:
I think this is what you'll have to do. If your issues continue, please return your devices ASAP. You could alternatively try to flash the Stock Kernel zip I posted earlier first, to see if that brings you back to booting. Are you sure you have the A700 instead of the A701's?

I'm planning on revising my build instructions on SDX soon, and I'm considering taking all conversation on this there. Will you guys follow? Is there anyone else willing to learn some with me? It wasn't nearly as hard as it seems. If you have any old DOS common sense and any programming knowledge at all, the general structure is pretty straightforward. If I don't get any followers, I will keep posting here instead, I just hate clogging a thread myself.

To all who haven't tried, the Nook Color development would not have gone nearly as well as it has if not for the plethora of people who just wanted to learn and try. I didn't get in on the ground floor of that one, but this is a great tablet to learn on. You can still pick these up online for about $60, and they're worth it in my opinion, especially since they tend to be great for this kind of learning (unbrickable much!). Jump on the wagon and give noob development a go.

Not getting a lot of response on SDX, so I'm going to fish here.

I've been trying like crazy, but I think there's something with using the prebuilt kernel that's throwing things off in building.

I've tried everything that I have found googling to no avail. I can't see anything else that would be different. I wish I knew that I could build a kernel and make it work with our tablet. If we could only get our hands on the source code.
[Android Q&A, Help & Troubleshooting] mthous01:
Maybe it's just my inexperience, but I'm wondering why when the 33.6MB nandc.img is split, you get a zImage that is 4.6MB and a initrd.img that is 396.2kB. Where did the extra data go? I've used abootimg to repack the zImages that I have built, and some flash, some don't. Does this system require a image file that is exactly the right size in order to flash?
[Android Q&A, Help & Troubleshooting] BLuFeNiX:
Any .img file copied from a device's partition is going to be padded with zeros (since it's a byte-by-byte copy). If you know where the data ends and the zeros start, you could (theoretically*) just flash everything before the zeros. I hope that answers your question.

* You might need some number of zeros following the data portion of the .img, but in my experience it does not matter. YMMV.
[Android Q&A, Help & Troubleshooting] mthous01:
I cannot get it to flash at all with a smaller file. I have tried building a kernel, using the unpacked ramdisk image. The boot.img file was only 9MB or so, but it wouldn't flash. I was wondering if it took making the file exactly the correct size by padding with zeroes in order to flash without failure.
[Android Q&A, Help & Troubleshooting] mthous01:
So I'm stumped. I have been able to successfully build a zImage from source. I have used abootimg to create an image file using the stock ramdisk and the stock bootimg.cfg. The resulting nandc.img file is 33,778,118 bytes instead of the original 33,554,432 bytes. The file will not flash to the nandc partition, (Installation aborted in CWM). I have tried to pack the zImage and the stock ramdisk without the bootimg.cfg, hoping that the smaller image would then flash to the nandc. It also fails. Does anyone understand the hex addresses contained in the bootimg.cfg, such that the original bootimg.cfg can be altered so as to make the final nandc.img file the same size as the original? Maybe this will get it to try to boot.

I guess maybe I did something wrong. I repacked it again, and the nandc.img file was exactly the same... still aborts installation. Huh...

Used adb push and dd to push the nandc.img to the /dev/block/nandc. doesn't boot, but does get to the second bootimage.

Got it to build and boot all the way to the home screen! The touchscreen works, but the entire system is as slow as molasses, and root doesn't seem to be working. But... IT BOOTS! Please join me on the SDX site to start working on cleaning this thing up!

<BTW, seems that uboot must be compiled along with the kernel to get a booting image.>

It's critical to follow all the instructions thoroughly (not to say you haven't) make sure to run the driver exe files, then start livesuit.exe, then plug in your tablet while holding volume up our down. It takes a minute or two for all the drivers to kick in and for the tablet to be recognized.

[Android Q&A, Help & Troubleshooting] mthous01:
I was hoping to see more people come over and begin to chat about how to dev for this device. I'm getting stuck on a few things, and could use some folks to test the most recent build of the kernel and see if they can pull some logcats, dmsg, etc. I don't have time to debug the whole thing, and some community support would be greatly appreciated.
[Android Q&A, Help & Troubleshooting] mthous01:
I've begin running logcats and dmesgs to figure out what's going on. I'm convinced that the kernel code I have is fractionally newer than the stock code (i.e. 3.0.8.15 vs 3.0.8.10). This means that some of the modules are broke. Primarily, I'm concerned with the Mali and the elg modules to begin with. I'm going to post a list of stock modules and a list of modules built by the custom source. If I could get help tracking down the source code for those items missing, that would be phenomenal.

hey guys, im a newbie here to this site and was wondering how I can overclock this azpen a701 tablet I got. I think its pretty similar to the a700 spec wise. I rooted it using vroot and as soon as I tried overclocking past 1200 with setcpu, which is stock speed, it would freeze. I searched the internet why and I figure I needed a custom kernel since stock doesnt allow overclocking as far as im concerned. sorry guys, I know nothing of android, roms, kernels-none of that. I use a Blackberry z10 thats why :rolleyes: I dont know where to start :crying: I read most of the thread and got lost pretty quickly.

CWM not mounting SDcard

Hi!

I'm new to all this, but anyway I got this tablet as a gift from someone although it came under a different name. Closer inspection revealed that they are exactly the same and I am currently running the livesuit recovery rom.

I was attempting to go back to stock with your zip but when I go into cwm(build 5) I get an error that says something like E:/ unable to mount sdcard.

I tried going into mounts and storage and the same error applies for anything that is related to the sdcard.

I have also tried build 4.

Any help would be greatly appreciated.
[Android Q&A, Help & Troubleshooting] mthous01:
Sounds to me like your partition table is a bit different from the A700/A701. Do you know anything at all about ADB (android debugging bridge) or the Android Terminal app? If not, these will be necessary to pull your partition table info and see if a CWM can be built for your tablet.

These are all for the A700/701. You can try, but without a livesuit firmware to fall back on, you could brick your device.

Then upload stock_recovery.img somewhere and link me to it.

2 things to note though.

1. This recovery was running on my brother's tablet which is running ICS not JB. Unlike mine. I doubt it will make a difference but just putting it out there.

2.When I run the cwm recovery for the A700 on my tablet, the volume up and down buttons are inverted. If you could, can you make them right again?

Thanks again!
[Android Q&A, Help & Troubleshooting] BLuFeNiX:
1) This should be fine.

2) Unfortunately, I don't know how to fix this (it's the same way with the A700). If anyone knows how, I'd be happy to hear. I suspect it involves compiling CWM from the ground up, which is not what I have been doing to make these releases. I just found a working CWM for a different device and injected the necessary kernel modules and filesystem information.

I'll try to take a look at this tonight and send you a test build. I can't promise that it will work correctly the first time, so be prepared to flash back to stock via Livesuit (or whatever other method your tablet has), in case something goes wrong. That being said, I suspect it will be fine.

[Android Q&A, Help & Troubleshooting] wkearney99:
For anyone curious, the Kidigi wireless charging dock (meant for a Nexus 7) does not work with an A700.

I've got an add-on microUSB Qi charger pad for the A700 (sandwiched in-between the tablet and the fold-up case). It works reasonably well with a flat charging pad (in my case a Docooler charger).

Unfortunately the slot in the base of the Kidigi dock is too thin and the A700 won't fit, even without a case on it.

Weird. Can you bring up an ADB shell in CWM, run each of these commands and post the output?

mount /sdcard
mount
cat /proc/partitions
ls /dev/block/
df -h

Make sure you are in CWM, not Android, otherwise the block device mapping will be different.

Also, one more command that is a bit more work:

dd if=/dev/block/nandi of=/tmp/fsdump.img bs=512 count=1

This will make a /tmp/fsdump.img file which you should adb pull and send to me. This will allow me to make sure there isn't something funny going on with your SD card partitions. (Don't worry, it won't contain any of your personal data, just the first 512 bytes of the block device.)
