CWM Recovery with UBIFS Support For Amlogic Nextbook Tablets (Support Thread)

[locuraconsigueusted]

For whatever reason, that didn't fix it for me. Settings force closes when I click "Storage" and I cannot save anything to the sdcard, even though it says it mounts. And I can boot from the sdcard, so a broken card or slot is not the issue... Any other ideas?

UPDATE: It seems that my NAND (Flash) storage is not being mounted either... Nothing in the /storage/sdcard0 folder...

I'm working on CM10, because I had to start the device trees to create CWM and this was the best base available with UBIFS patches already created. It continues to offer the least work to get something usable.

If I get it working completely, then it should be simple to use the same device tree for other ROMs like Paranoid Android or PACMAN. It should also be simple to start updating to newer Android versions, although we still need a new kernel before we can boot newer Android versions.

Any chance of uploading to github? You can use SmartGit/HG (gui for github). You can use the deb package to install in Ubuntu 13.04, just double ckick on it in file manager. The jellybean kernel should boot any version of android but may have problems mounting filesystem and camera, bluetooth may not work. Plus for 4.4.2 you will need a newer version of TWRP, not sure about CWM.

This can be really frustrating to solve. Sometimes it takes more than one try. Here's what almost always works for me:

1. Shutdown
2. Remove the external SD Card
3. Boot to the stock internal Recovery
4. Wipe Everything (Twice)
5. Restart
6. Verify internal partitions are mounted properly in settings.
7. Reinsert SD Card

That almost always works for me. On a few occasions, I've also found it necessary to reformat the external SD Card in addition to doing the above.

If that doesn't work for you, please advise what steps you took to fix your WiFi issue. Maybe that will give me some additional clues.

I intend to publish to github eventually. The main thing holding me back is my lack of experience with github combined with my lack of time to learn right now. (I'll take a look at SmartGit/HG).

I was under the impression that the 3.0.8 kernel would not work for anything newer than 4.1.2 or maybe 4.2? Perhaps I was mistaken?

The filesystem and partition layout are a big problem, because they are hard coded in the kernel.

Most of the nextbook models don't have internal bluetooth. Other hardware drivers can probably be insmodded if necessary.

I intend to update CWM / CM incrementally after I get a stable device tree. Switching to TWRP shouldn't be too difficult if necessary, but so far the TWRP builds that I have tested have had such horrible touch response that I won't release them. I may take another look in the future to see if the touch response can be improved.

cm-10.1 for the Prestigio Multipad Pmp5580C Duo works on the NX008HD8G/NXM8000ND_WM, no hw accelerated video, bluetooth or camera. http://forum.cyanogenmod.com/topic/6...-pmp5580c-duo/

The kernel should work up to 4.3.1, maybe not on 4.4.2. I would like to see PAC-man 4.3.1 ported, my favorite rom.

This is awesome! I remember seeing this request, but I was unaware that it had been developed. I'll definitely play with it. Hopefully I can find the source code used for it. I'm sure I could merge parts of it with my own and Christian Troy's to further my work on all the Nextbook models.

I believe the Prestigio model is the exact same thing as the Next8HD8G-NXM8000ND_WM. I strongly suspect Prestigio is either owned by Yifang (Like eFun/Nextbook is) or buys their tablets from Yifang. The Next8HD8G even has a the following line in it's build.prop: #ro.usb.product.string=PMP5580C

Not sure about the Prestigio model, but the Next8HD8G DOES NOT HAVE A BLUETOOTH chip... hardware acceleration and camera should be fixable by swapping files from the stock ROM.

I've never used PAC-man, but it looks interesting. It should be possible to build PAC-man or Paranoid Android from the same device-tree used for CM, with few changes.

Do you know if the CM ROM for the Prestigio uses UBIFS or EXT3 or EXT4?

ShaunMT

P.S. I just noticed that this is actually Christian Troy's ELF2 ROM, plus a patch for the Prestigio. It uses the same source code I'm already working with. Examing the patch files should answer some of the questions I've been trying solve.

i will test for u shaun let me know ok sounds like it b great

I'm still doubtful that I'll have any alternate ROMs ready for testing anytime soon... but'll look for you when I do.

Christian Troy only released the source for jellybean. The 4.2 and 4.3.1 versions of android changed the way file system mounts for multi-user. The first post is made from ICS, screen rotation is correct. I am trying the 4.3.1 and screen rotation is wrong. Might need to change the build.prop to the one from our tablet:

ro.sf.hwrotation=270
#0~7 You are required to get the correct install direction according the sensor placement on target board
ro.sf.gsensorposition=6
ro.sf.Gconvert_x_y=0
ro.sf.Gconvert_x=1
ro.sf.Gconvert_y=1
ro.sf.Gconvert_z=1
ro.sf.ecompassposition=4
allow_all_orientations=1

Do you have any idea how to unpack the boot.img? I would like to compare the rc files from our tablet to the ones from PMP5580C.
nnlynx has ported cm-10.1, cm-10.2, cm-11.0, and ParanoidAndroid 3.99 to the PMP5580C.

Screen rotation has been a pain. It seems like the build.prop, display and touch drivers, Open GL config, display config, hwcomposer, frameworks etc... all have to match up correctly. Amlogic does something strange to change default orientation in the Android source... so far I've managed to get it working correctly in landscape and portait, but not in upside down landscape or upside down portrait.

I use CXZ's scripts to unpack boot.img. You can find them in the Ainol forums at Slatedroid.

From this forum. http://forum.cyanogenmod.com/topic/6...-pmp5580c-duo/ I tried cm-10.1 and cm-10.2, just follow the instructions. I used Shaun's CWM to flash but there is a TWRP in the forum that may work.

I followed your directions, and it did not work. All I did to fix the WiFi was reflash the stock boot.img. Under where it says "flash storage" it says 8 GB, but nothing else. When I insert the sdcard I get the same issues as before. Maybe if I flashed the cm 10 that was mentioned earlier...

Not sure about the Prestigio model, but the Next8HD8G DOES NOT HAVE A BLUETOOTH chip... hardware acceleration and camera should be fixable by swapping files from the stock ROM.

From the looks of it bluetooth is achieved by use of some external USB dongle, not actually built into the device.
