Hello

I recently purchased a Ramos X10F on an impulse buy on a trip to the PP last month. I had been waiting longer than a year for an 8" 4:3 device that was not Apple with expandable memory and this one just made me succumb. Also I fell for the false data in marketing it as a cortex A9 and I thought a quad core A9 should be faster than my dual core A9 in the n7000. Actually it is a A5 or A7 (device details in cpuz mention some A7 blah).

The device has great potential to be an ipad mini killer (at $165) as the hardware fit and finish is very good, the screen is IPS and it weighs only 360 grams. I can hold it in one had lying in bed without tiring myself. However performance is marred by the stock android 4.1.1. Intially I thought it was slow nand flash as when I enabled cpu stats, the nand-rw-flash process appeared to be the top process for a longish time, each time it stalled. However I later discovered, the device is very laggy when Wifi is on while actual WiFi throughput is very good - I get almost full speed 16mbs in the speedtest.net results. Unfortunately even with entropy seeder and a deadline or noop scheduler, the lagginess is only partially improved. Also the old linux/android decision of using input to randomize and seed the entropy is only good for desktops not servers or touchpads. I have to tap a few times to get a app screen to respond inexplicably and suddenly and it shows that the OS was waiting on input. The device is best for streaming as typically once the app is opened I never have a problem with lag a it is typically 15 to 30 mins of viewing before switching apps. Otherwise the poor performance means a task that should take normal time (like reading news in the morning for 15 mins) takes more than twice the time as I have to struggle with the slow app launches and screen loading mostly. But if Wifi is switched off and content is cached, everything is smooth and much better. Battery life is decent with display brightness set around or below 10% typically.

So my recommendation for a new buyer is - dont buy until a custom ROM is made available. Dont fall for the x10pro video on the utube yet. Real world performance is not the same. Once the smoothness of the 4.4.x is acheived it will be a killer product. (It is not a weak cpu either, it is responsive and smooth with wifi off. Although the chip does not support out-of-order execution)

I would like to upgrade the android from its 4.1.1 to a 4.4.x version. Also this version is vulnerable to heartbleed and the openssl bug that came after that in June 2014. The omnirom 4.4.3 on my n7000 is really smooth and I am hoping somebody will develop a custom rom for this device.

But I dont see a custom ROM or CWM for this anywhere. I installed a CWM recovery for another ATM7029 device (yarvik) and it boots, but I forgot about the display driver compatibility and I can no longer view the menu in recovery mode. Otherwise rooted it and running ok.

What do I need to submit for a developer to build a custom rom for this device? Some kind of dump? Also need a recovery manager with the right display driver. Either TWRP or CWM.

I hope a developer will volunteer.

Thanks
