I was asked to. The device works, but does not enter the recovery - it hangs on a black screen.

It was such, until I fixed the address where to flash, as I wrote above

By the way, our core supports ZRam, I have set myself up, a bit more RAM now. Who cares what it ishttps://ru.wikipedia.org/wiki/ZRamandhttp://habrahabr.ru/post/172137/, instructions for setting up can write a little later, if interested. Everything is quite simple there.

Something I'm not quite sure about the usefulness of this. For his work, a piece of RAM is bitten off, which is so small.
So where will it suddenly become more?

The question is not in quantity, but in the effectiveness of its use. Swap, in simple terms, the continuation of the RAM, but on the disk. We create a swap in the same op. memory, but use compression on the fly. Thus, cutting off, say, 64 mb, we win about 100-200. Naturally, this works when the "normal" op. the memory is filled by n% (n depends on the setting of the swappiness parameter in the system) and the system begins to "swap" the data from it to disk. Additionally, we win in speed, the read / write speed of RAM is higher than that of a flash drive / HDD.
By the way, I have also limited the max. CPU frequency, for the sake of autonomy. Well, something else is configured, I can share. Everything is implemented in init.d scripts

I know that. It has long been set up. 9 hours in the sudoku game mode at full brightness with the included waffle, Google services, reminders and other junk (reports mail, package tracking).
As for - the memory is faster. Oddly enough, I have the internal flash memory of the tests slower than the external card. Map class U1.

So we are talking about RAM memory, a swap is created in it, and not on flash drives (whatever - internal / external, RAM is a separate chip), the difference in speed is several orders of magnitude. That's the whole highlight of the ZRam. By default, we generally do not have a swap, even on a flash drive.

No, I meant that I swapped the internal flash and the external one (by editing the firmware) and got a decent gain in speed + set up a swap.
You can certainly see what will ZRAM. Another question is that the device is very much "budget" and expect more from it - well, it's just not realistic.
Although the maximum, I think, have not yet squeezed :)

Made by user MiceRus from standard from manufacturer.
Take here.
Do not forget to plus the author of the firmware (the topic is not mine, I just posted a link)
Together we ask the author to raise the creation in the topic header!

I asked for the instructions and the tablet died
when launched, it gives the name "SUPRA" in a faded form, and so on in a circle.
Tell me how to return to life ???

It seems to me that you were using the wrong version of the firmware. Try another one because such a white intsindent met on phones with firmware without a kernel.

Hello!
For those who can not install the driver, then to flash, advice (although if the tablet somehow loads), press the Switch button in the Rockchip Batch program and it immediately goes into the firmware mode and the drivers get up without problems, later you can properly flash the instructions In the cap through Rockchip Batch.

I could not get into the recovery in any way, the tablet was locked with a graphic key.

Guys, share, please! I hope for this (editing scripts and all that) you don't need a higher one. tech. education? And it will be possible to roll back, it will not turn into a brick? Gee, thanks for the answer.

All I did was described inPDF file. Step by step.
If you have another version of the tablet - then just take and download your firmware and disassemble it.
As for reducing the frequency of the processor, there are a lot of programs for this in the same Google applet.
However, after playing for a month, I deleted it. I don’t know if she left her settings or not.
And for fine tuning, I use three programs:
Wakelock detector
Disable Service
All-In-One Toolbox
This is quite enough for a normal NOT DANGEROUS setting.
