[Q] Gemini Devices GEM7020 - 7" Tablet - Android Q&A, Help & Troubleshooting

Can anyone provide me with info for a custom ROM for this tablet?
I have looked everywhere but cannot root the thing and cannot find any roms other than the stock one.
I am having some very bad wifi problems with this ROM. Disconnecting and reconnecting, hanging on connecting/obtaining ip address. etc
Was hoping someone could provide a more stable ROM.
I can use the device as a test for someone if they want to help me cook a new ROM
Any help would be appreciated.
Thanks
Ballz
Maybe this info will help :-

[Q] Custom ROMs for Navcity NT-1710?

Hi, I've been looking around for a while for a custom ROM for my Navcity NT-1710 tablet without much luck.
I came across this thread for CM10 for Allwinner A13, which my tablet supposedly has, but upon further inspection on the thread for CWM, it says the "Hardware" in CPU info should be either "sun4i" (A10) or "sun5i" (A13), while my device returns this from ADB:
Code:
[email protected]:/ $ cat /proc/cpuinfo
cat /proc/cpuinfo

CPU part : 0xc09

Hardware : WMT
Revision : 0000

Does anyone have any idea whether I have another processor (and the company lies to its customers), or this could be some sort of misreading and I can still install CM10 normally? Thank you.
I’m looking for a custom ROM too, but without lucky....
I'm even thinking that I should make one, but without CWM it's futile.....

[Q] XBMC on rom UGNA7 not working 15.02.14

Hi to everybody!
I was on mk6 rom and had my xbmc 13.0 working perfectly. I updated to ugna7 and i get an error parsing cpu features.
I tried downloading the latest nightlie and didn't fix it.
I've read in some thread that the problem maybe is in proc/cpuinfo.
I wrote in the xbmc forums trying to find help but nobody answered. This is my thread:
http://forum.xbmc.org/showthread.php?tid=186026
and this is my cpuinfo:

maybe someone is on mk6 and we can compare it ? maybe i can modify it so xbmc works ?
I have exact the same problem on ugna7 and boeffla kernel.
Does only matt and I having this problem?
Here on xda there are so many people with great knowledge and skills. Why nobody writes anything?

lenovo A820s ( i phone think this is a clone of a A820 )

Hello I´m Antonio from Portugal .
I have this phone , lenovo A820s ( think this is a clone of a A820 ) , I´m very , very newbie ...
I´m trying to root this phone... but always fail !
the "project " is to backup the original software and after install a new Rom more "clean" , without the tons of apps that I don´t use ... and free some space because it has 1G of ram ... but is always at 92% full ( this confuses me also ) .....
The current problem is I can´t root the phone in the first place , but from the cpu-z report there is one thing that confuses me ...

Other omap4 based tablets rooting?

Anyone know if a generic tablet using the omap4 cpu (OMAP4430 dual core 1k mhz) can use the cyanogen rom for the archos? Picked up this pos for $13 (still overpriced) and am have a tough time finding a route to root and the archos seem about as close a cousin as I can find, thanks..
http://www.amazon.com/gp/product/B00JDRYKHK?psc=1&redirect=true&ref_=oh_aui_search_detailpage
Your link on Amazon gives 404 error. It's hard to tell beforehand, Archos boards have slightly modified kernel in comparison with Blaze platform (TI OMAP4 processors). Do you have /mnt/rawfs/tags file on your device?
Yeah listing has disappeared and I don't see a way at /mnt/rawfs/tags without root, I just did a factory reset though and am using the built in fm, don't have es on there, each time set this thing up through google it slows to a crawl and is close to being introduced to a brick wall..
This is the best tech info I've found so far, as far as I can ferret out this is the cpu it's using, really need to figure away to root on this pos..
http://system-on-a-chip.specout.com/l/388/Texas-Instruments-OMAP-4430
emailed svp support.. giving 1/100 odds that they are of ANY help..
Yup, you need root to read that file. It's FTAGs file with device's TAGs of it's parts (CPU, memory, display, etc.). This file is used on Archos devices for initialisation. Without root you may try to type "lsmod" to figure out your drivers/devices on your tablet. Also "uname -a" will give you current kernel without root. Also try "cat /proc/cpuinfo" and "cat /cpu/meminfo." Also you may try to investigate inside /sys/ directory for devices and its config and so on.
Uname-a and /cpu/meminfo not found

Did I say "cat /cpu/meminfo"? Sorry, it was misspelling. Use "cat /proc/meminfo" instead. It will show memory of the device. uname command probably doesn't present to save up a bit more space.
What's the name of your device BTW?
"Hardware: gs702a" isn't device name, it's most probably the name of the motherboard on your device. Ainol Novo7 Venus device may also have this board. I don't think Archos gen9/gen10 kernel is compatible with "gs702a" boards. Take a look there:
https://github.com/archos-sa/archos-gpl-gen9-kernel-ics/tree/master/arch/arm/mach-omap2
I don't see board-gs702a there. Maybe you should try to search in older Gen8 kernels, IDK:
https://github.com/archos-sa/archos-gpl-gen8-kernel/tree/master/arch/arm/mach-omap2
Also do not see any gs702a here. You may try to look also in gen7/gen6 yourself.
Also, your modules from lsmod look very different. Here is an example of lsmod on Archos 80 G9 Turbo (A80S board with OMAP4460 ES1.1 CPU with Cypress tma340 touch screen chip modification):
$ lsmod

Also be careful. Make full backup of the whole MMC or other storage you have on device. And try to install some kind of Special developer edition firmware (backup menu in case some kind of partition is bad and do not load). Different devices may have different partitioning schemes with a lot of different partitions on the same device. Also, you should know that Archos firmware is encrypted and there are decryptors for it. Also, Archos kernel is signed, you will have problems with it because of checksum mismatch (if you will be doing strange things without understanding). There are also special tools for firmware modification like ACT Pad Firmware Modify Tool. But you should know what you are doing and double-check if you do not want to brick your device.
Ok, thanks for your help, I was guessing that this might be compatible. At least you got me thinking linux rather than android, funny if I install linux I usually don't even install a gui and use ssh for everything, but with android it just as likely I won't even have terminal installed, pretty good trick hiding the linux bones so well you forget it's just another desktop env.
And since I reset, and have not mainlined the goo, (ie not entering any google account info) I've side-loaded my apps instead, and it's running reasonably well vs slowing to a crawl once it gets hooked on the goo, so I'm sticking with the side, and kids.. just say no to the goo!!
thanks..
