Unfortunately, there are no official firmware from Megafon in public access.

Official updates
Updates distributed by MegaFon on FOTA (updates "over the air"). This method is not optimal, because checks the originality and integrity of each file being replaced, thereforeInstallation is allowed only in the correct sequence, with version control and strictly on stock firmware. Those. if you made any manipulations with the firmware of your device (received root, put patches, replaced recovery or any other component) - the installation of these updates will not be completely completed, which is guaranteed to lead to problems during operation.

Use this update method only if you know exactly what you are doing!


v5.2.5.0- it was in this update that the ability to transfer applications to the SD card appeared.Screenshotsfrom 1375maximus
v5.1.8.0
v5.1.6.0
v5.0.9.0- This is an update test, when you apply it sequentiallycan't(i.e. after 5.0.8.0, you must install 5.1.6.0 right away).

The easiest way is to use the vebs BigButton script, performing installation of patches without permanent firmware modrekavery into the device (only one-time loading it into memory is performed).

- Is it possible to install only patches from vevs through BigButton, and the rest through moderation?
Through BigButton you can putanything.

- After selecting a patch, the message "error: more than one device and emulator"
You must first remove the Android emulators installed on your PC (like Bluestacks).

- When flashing via BigButton, the adb server did not ACK error appears
Solution 1from leo150;Solution 2by piont

- Is it necessary to enable the “Debug USB” mode in the “For Developers” menu before installing the ADB drivers when flashing through BigButton?
No, FastBoot mode and ADB in Recovery are in no way connected with the setting of this parameter. Those. if it's about working with BigButton, the scheme is:
1) launched in FastBoot ->put the driver ->checked in the window
2) Recovery is booted ->put the driver again ->checked in the window.
And the firewood for the already loaded tablet - if necessary, we put it for the third time. In all three modes, different usb_id.

In Russia, the tablet will only work with a MegaFon SIM card (it is locked to the operator). At the same time, the SIM-lock is installed so that abroad the tablet will work with any SIM-card of local operators. That is, the list of prohibited networks is limited only by Russian competitors.

It is possible to restore a SIM-card lock only with the firmware of your own image created by the HDDRawCopy program.! (see spoiler"RESTORATION")

FAQ
- Who is the author of this topic?
The author and honorary curator is a respectedstudmix88

- How to maximally (but safely) increase the capabilities of MegaFon Login 3?
1. Create a system image of the tablet program HDDRawCopy (see spoiler "RECOVERY")
2. Install the modified firmware from Vevs'a (ALL preinstalled third-party software has been removed, Google services are pretty thinned out, root installed, modified recovery, audio patch installed and a full-featured (as far as possible in KitKat) SD card, menu enable_adb in the Qualcomm service menu) (see spoiler "FIRMWARE / Firmware / Unofficial firmware / Modified") using BigButton (see spoiler"FIRMWARE / INSTALLATION"). For the modified firmware 5.2.5.0 from Vevs'a also install a patch for full-fledged work with an external memory card (see spoiler" FIRMWARE / Patches ").
3. If desired, unlock the SIM card (see spoiler "UNLOCKING")

- OTG is?
Not. I repeat - not at all! And it will not be! And through the engineering menu will not, and with external power will not be! Not at all!

- Is it planned to update the operating system installed in MegaFon Login 3?
No, the Android version will not be updated.

- Is it possible to correct the decrease in the sensitivity of the microphone in the official update v5.2.5.0 from MegaFon?
Yes you can. Take advantage of "a patch to improve the sound in headphones"from vevs (see spoiler"FIRMWARE / PATCHES") or modified firmware from vevs, which already contains this patch (see spoiler"FIRMWARE / Firmware / Unofficial firmware / Modified").

- Do you plan to release a new patch by MegaFon?
Yes, there will be a patch related to the bug of degrading microphone sensitivity in version 5.2.5.0.

- Is it possible to make a backup of the tablet before performing actions on firmware / software update / patch installation?
Yes, it can and should be!It is strongly recommended to make a backup of the system using HDDRawCopy before updating, flashing or doing anything dangerous with the device!(see spoiler "RECOVERY").

- Is it possible to restore the tablet performance after unsuccessful actions or failure?
Yes you can (see spoiler "RECOVERY").

- Are there official firmware for MegaFon Login 3?
Unfortunately, there are no official firmware from Megafon in public access.

- Is there any unofficial firmware for MegaFon Login 3?
Yes there is. Modified firmware from vevs. They removed ALL of the pre-installed third-party software, pretty thinned out Google services, installed root, modified recovery, audio patch and implemented full (as far as possible in KitKat) work with an SD card (see spoilerFIRMWARE / Firmware / Unofficial firmware / Modified").

- Does MegaFon Login 3 have a custom counter?
There is no service counter that identifies the number of non-factory firmware flashed into MegaFon Login 3.

- Is it possible in the modified firmware 5.2.5.0 from Vevs to achieve full-fledged work with an external memory card?
Yes you can. Install the patch for full-fledged work with an external memory card from Vevs'a (by turning off the internal emulation) (see spoiler "FIRMWARE / PATCHES").

- What are Root-rights and what are they for?
This is an administrator account giving you unlimited control over the system. One should be aware that even obtaining Root rights is an invalidating guarantee, especially if after the changes made in the firmware it is not possible to roll back the system to its original state. Before going to the service, in order that you would not be denied a Root access guarantee, you will need to delete it.

- Is it possible to get Root in MegaFon Login 3?
Yes you can. Take advantage of "patch to get Root"from vevs (see spoiler"FIRMWARE / PATCHES") or modified firmware from vevs, which already contains Root (see spoiler"FIRMWARE / Firmware / Unofficial firmware / Modified") using BigButton (see spoiler"FIRMWARE / INSTALLATION"). You can also use the program"AutoRoot for v5.1.6.0 and v5.2.5.0"from Ruslan2001 (see spoiler"DIFFERENT").

- Is it possible to safely remove some programs after receiving Root?
- Yes, you can.

- Is it possible to unlock the tablet to work with SIM-cards of other operators (Beeline, MTS, etc.)?
Yes you can (see spoiler "UNLOCKING").

- Can I overclock the processor?
Not. So far we have a limited set of governors and the regulation of the frequency is only down.Undervolting is not available.

- Is it possible to install microSD on 64Gb?
Yes, it is quite possible, but remember that the maximum, stated by the manufacturer of the tablet, the amount of memory card: 32 GB

- Is it possible to transfer applications to the SD card in MegaFon Login 3?
Yes you can. Use the official update v5.2.5.0 or (the best option) with any modified firmware from vevs (see spoiler "FIRMWARE / Firmware / Unofficial firmware / Modified").

- What is Recovery?
This is the bootloader mode, created to be able to restore the device in case of damage to the firmware, etc. Factory Recovery allows you to flash only the original factory firmware. It has a minimum set of functions.

- Are there any alternative CWM or TWRP assemblies for our device?
Exist. There is a TWRP.

- How to decrypt the error that appeared in the Recovery mode?
Use the "Volume +/-" button to select the menu item "Apply update from adb"Recovery mode. Error decoding is contained in the string"EMMC: / xhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh" has unexpected contentswherexxx- and there is the content of the error

I flashed it on universal from vevs_a, better, but not a fountain either ...
I remembered mGapps. He demolished all Google, deodexed, installed microgaps.

Good afternoon. Kick pliz in the right direction, but there is no way a stone flower comes out.

The tablet began to constantly issue errors of system applications, resetting it to the factory state did not help. I decided to reflash it. Re-read the instructions - nothing happens. Drivers are, backup made, the tablet seems to respond, but .. no way

Here, for example, he gives such pictures when trying to download recovery via BigButton, which would then go to the firmware. If you load the firmware without this item, then the essence does not change, so is the error and that's it.

A patient was brought with the same problem of "encryption", the regular v5.2.8.0 rekoveri.
Firmware rekoveri did not help, as did wipe.
It was possible to flash through Bigbutton this morning, it did not help either.
(It was not possible to flash through Bigbutton TWRP, but during the download you can use it once).
Interesting things were discovered (I don’t attach screenshots, if I need to do it in Mon).
In fact, there is a problem with mounting data (maybe because of "encryption"). Its size is zero. Formatting, checking the disk, changing the file system does not pass.
Subtracted here on the forum about the double clamping of the volume buttons and that's what I have now in disk management

Particularly interesting is the S drive ... Can it be formatted in FAT? and then in TWRP reformatted to ext4.

P, Q, R also in RAW.

What to do with the other sections? If (it turns out of course) to beat them all up and then reflash, will the memory be redistributed?

The data on the tablet do not care. It is only necessary to revive.

And a working instruction created on the basis of the latest available files from vevs:
Does login3_vevs_system_528_universal and bigbutton3.1 exist in nature?
In the header, half of the instructions are either missing or use other files in
as the source. Accordingly, there is no hope that all that needs to be done
will go as it should. And that instead of a hypothetical action point 2, I will not click
unnecessary point 4, just because it went according to another instruction. Or vice versa:
need to do some extra steps because new / updated files are used for
installation, but I will not do these steps, because I go on the old manual that does not take into account
the fact of the novelty of the firmware files ....

P.S. obviously, something is not done according to the old dock for new files.
The firmware has risen, but it is impossible to go to Google account. Eternal login error
or password. Although 100,500 is exactly what was introduced. Hike in new
the firmware files are either cleaned up or pre-unpacked to some kind of
states when you need something else to add. Gaps, or something else ...

You probably had some kind of error before the flashing, or occurred in the process?
I was lucky)))))
Before flashing it was one of the first versions of the firmware of Veus. The child was missing. But something littered everything. Decided to update. And .... There are no old files. The new instruction is not attached to the new one. For good luck, I went through the old memory of well-known buttons and it seems like the firmware itself got up .... But you can’t figure it out with Google ...
