In general, it should work if their memory 512 (userdata) + 2048 (internal sdcard) will be equal to ours

[mcnaci]

I confirm. works. really had to do the restoration twice.
Now under / data 2.5 GB.
internal flash drive 19 MB.
the question is - is it possible to modify the script for moving memory in such a way as to hide this piece at all in 19 MB?

Hello, guys help me save, I bought myself m84g, everything seems to be okay, the problem arose when installing games with a cache, the cache rushes to the internal memory, I put the hook on it, the label is there, and the cache in the internal memory, I throw a copy of the cache he doesn’t see it on my flash drive, and starts downloading a new cache when starting the game ((((che to help me please).

[mcnaci]

after using vold_ed.zip, flash drives have changed places, but in the settings in the memory view, how much space on the flash drive does not appear.
Is it inevitable or can it be cured?

[kitt]

I took my device to the service (and a couple more), it was specifically for this device that the SMS came, saying that the defect was discovered, agree to a replacement), but I’m rubbing the roll, I will demand money back, or replace all three DNS-tablets (totaling 21 tons). r.) by twohttp://saratov.dns-shop.ru/catalog/i159743...io-pmp9100.html. My trust in the CSN brand has been exhausted.

Something I did not understand the humor of mounting drives: (
Internal Memory: 0.98 GB
Internal memory: 16 GB (my flash drive)
SD card: 1.58 GB

men, generally expected normal build 4.1.1 / 4.1.2 on dns m84g or not? The official firmware is terrible, and those firmware of adjacent devices that are laid out are not perfect with jambs !!

Specify which firmware you tried with the names and links and what are the imperfections and jambs)
I used my native 4.0.4 for a week, then 4.1 beta from explay surfer 8 / 31g, now I use 4.1 from ross & moor 877g
Except for the lack of dialers for the firmware of the jambs I do not see

What is vold.fstab.nand responsible for?

And as usual, I myself answer my question:
Contents of the /etc/vold.fstab file

dev_mount sdcard / mnt / sdcard emmc @ fat / devices / platform / goldfish_mmc.0 / devices / platform / mtk-sd.0/mmc_host
dev_mount sdcard2 / mnt / sdcard2 auto / devices / platform / goldfish_mmc.1 / devices / platform / mtk-sd.1/mmc_host

Vobschem then, if the memory does not change me, everything is exactly the same as it was.
But I made changes to /etc/vold.fstab.nand:

dev_mount sdcard / mnt / sdcard auto / devices / platform / goldfish_mmc.0 / devices / platform / mtk-sd.0/mmc_host

The only thing that did not like:
/ mnt / sdcard - External Memory
/ mnt / sdcard2 - My 16gb mSD
/ sdcard - mounted my mSD
As it is not for Feng Shui :(

Stitched on 4.1 Ross & Moor 877G, the tablet does not even turn on. The same fate befell with ikspleevskoy prosh: (
Do you guys need to describe the firmware process in more detail?
What items should I choose in the SP FLash Tool?

From eksplaya 4.1 I fixed it by selecting all the items, only the recovery immediately indicated the custom, but through the Firmware Upgrade button

Shl. as for changing the mount points of the cards - this manipulation in vold.fstab was enough for me

Either I myself was very stupid, or a computer, or this is a fatal combination of circumstances, but now all the firmwares have risen perfectly. The only thing - flew imei to 4.1 from ross & moor 877g. He does not want to recover yet.

Hurray, I finally defeated my Chinese vrazhin, I managed to change IMEI through the system menu, so who is interested, we do this:
1. Click on the button to dial the number and enter * # * # 3646633 # * # *
2. Get into the engineering menu and select: "CDS Information", "Radio Information", "Phone1"
3. In the topmost field, where it says AT +, we add EGMR = 1.7, "your_imei1", in the end, we get the string AT + EGMR = 1.7, "your_imei1" and press the "SEND AT COMMAND" button
where your_imei1 is your imei for the first sim card
4. If you need to register imei for the second SIM card, then in the same line type AT + EGMR = 1.10, "your_imei2" and again press the "SEND AT COMMAND" button
5. Exit the engineering menu and reboot the smartphone
6. Check your imei by dialing the code * # 06 # in the dialing string

Ps I only have one imei displayed, although through the same engineering menu you can see that there are two

By the way, it is quite possible that root method is not needed for this method, since the command is executed by the system utility.
