Rep: (380)
* Specter0 , From your description I suspect that the flash memory is transferred in read-only mode
Instructions on how to check

P.s: A store finally behaves strange if you did not have installed Root rights the failure flash memory is like a warranty case



Rep: (3)
Now through it and checked these two errors highlight, also pay attention to the analysis of the errors in the absence of NAND flash memory (in the screenshot above hit the frame) or UFS ignored if your device type EMMC. how to understand it ... they guarantee was released and told that nothing can not help, go to the SC Tipo do you and will continue to use ... and they are supposed to exchange facilities or refund within 14 days if the buyer something does not fit ... went to the SC said that 3 or more weeks will be a current diagnosis of why the heck should I wait if I want a phone today. I bought a pancake

Specter0 @ 13.01.18, 11:22*
how to understand it ...

Everything is very simple)
There are 2 types of memory and NAND EMMC
EMMC - less, read write speed is smaller and not as reliable
NAND - more expensive to produce, higher speed and probably more reliable than the EMMC
Chinese in most vehicles just use EMMC, an error of this type
ERROR: NAND Flash was not detected!
pay attention because it is not necessary This error just goes to show that the NAND-type memory is not found

And now gradually move to the second error
You as an ordinary user to test the firmware or the phone using a USB cable which is why getting the error in the log window
ERROR: UFS was not detected!

This error is typical because UFS is a simple programming device (which is usually employed in CC)
And it deciphered as the error sounds something like "The programmer is not detected"
P.s: these 2 mistakes are common because of what your phone is not worth paying attention to it

Rep: (3)
Now the question: -How be) there is an option to make the phone or carry a warranty ... for pay for the repairs to 1500 half the cost of the phone and certainly not hunting tembolee 3 day phone use ...?



Rep: (380)
* Specter0 , I think that you think the phrase "do it yourself"
If you mean "at home" in them without soldering station and skills to do nothing
And if you mean "at his own expense," the flash memory replacement can be relatively expensive
Roughly assume that memory costs $ 10 +% of the work
So it is better I think to seek repairs under warranty, although 3 days is really a long wait ... but if the repair will be free then you can try to wait: /
P.s: this is purely my opinion



Rep: (3)
heh if only 3 days bylob is certainly not a problem to wait longer, and need 3 weeks because that would send him to another city where the diagnosis will make and then back to the phone ... only 3 days with both the store came out)



Rep: (380)
* Specter0 , Well, then xs: /

I decided to write in your subject, as Bravis a552 topics not nashol. All day yesterday trying to restore imei without a root. Imei restored if interested can describe the way.



Rep: (380)
* Rus21940 Describe, I think there is also your method ride



Rep: (0)
* Photon9,
I tried your way, but alas, the same error!
Familiar asked to remove unlock the phone (baby set and can not remember).
I did resset through rekaveri and as it turned out later that they and password from the Google Account can not remember (the phone 5 days after the shop and everyone has forgotten !!!)
According to the instructions, I accidentally erased the memory, then flashed firmware native, but the phone is not switched on! I tried different ways and eventually jammed it!
Now, as far as I understand it is necessary to physically vypayat memory programmer and pour it all back, and then solder it back!
I will seek the service center ...



Rep: (380)
* sj20001 Before looking for the SC and the programmer, let us do everything in order
When you connect the phone exactly how it determined?

Maybe 2 cases
1) MediaTek USB Port
2) MediaTek PreLoader USB VCOM
More computer can not see it, but judging by your posts it somehow so determines)

Orstudydecision his mistakes

* roma392,
Yes, it is defined as MediaTek USB Port

I understand it must be put into bootrom mode?



Rep: (380)
* sj20001 , You need only ask preloader

By the way one of the options is the low level of charge: / There may measure the voltage on the battery? Or recharge it with something? (Eg Frog)



Rep: (0)
* roma392,
At 3.9 volt battery, charge enough!
There are videos on YouTube that would have you watched it and suggested correctly I think that I have the same story?
https://youtu.be/Zc7avpXHOM0



Rep: (380)
* sj20001 Yes, the same story

Once you have most likely been deleted not only preloader but absolutely all other sections
You can try to recover since it is there (only desirable to have all the checkboxes at the firmware installed)

Specially finished watching the video until the end of it would be possible to tell you about all the nuances:
In the first test point of which he speaks is not the fact that the volume button + on my HomTom ht3 it is completely under the train buttons
The Action Plan is as follows: If you do not work with the "Volume +", try to click the "Volume -" or not at all with the "On / Off"

Secondly, not all phones can be sewn without batteries, so first try without it if it does not work then it

And thirdly, in the subject FlashTool'a say that you need a preloader to flash separately (That is, if the DA managed to call, but fleshtul when trying to fill all the firmware write error ->Try to call him as well, but this time only flash the preloader. If all will fill successfully ->Sews the whole firmware (without preloader'a)



Rep: (0)
* sj20001,
Thanks for the help, but the combination does not come to fruition! He seemed determined MediaTek USB Port and determined!

I feel the need to physically on the board to find a contact test point and lock it into the housing (GND)
But while it is impossible to disassemble the phone warranty!



Rep: (0)
Still there is an option that you want to try: Use the OTG cable to the connector or short micro USB 4th contact on the ground!
