[Sony Xperia M2] ChaarlyZ:
Hello, I ask for help and assistance, please.

Sony M2 - D2305

The whole tutorial was read carefully and followed as is, it was achieved, used and tried to meet the objectives happily, it is not my first flash, nor the first device to die (another lg L80 d375ar) I have vague concepts thanks to the forum and booble, I understand something. I am not a developer but I would like to go deeper, without more, I will give a description with my best effort and in the end I will go to the problem in question. (which arose from layer 8 human error in an oversight)

-the bootloader was successfully unlocked;

-I don't remember which flashtool version to use, I have 0.9.18-6 as recommended; following 0.9.22-3 (I think I used this); 0.9.25-0; 0.9.33-0; 0.9.34-0;

-all those files in theory means that then, they work, it was used very well (congratulations to dev's, great job);

-woow!! What's that? Did you launch a new updated version of the lineage, good! I want to try that now! (telling me);

TROUBLE:

Between so many times that I have done it, after doing the format, and the corresponding wipes ... I realize that I never inserted the sd card.

I slide on off.

There is no system, it does not light its LED light under any combination, its battery was at 100%, there is no dfu, there is no recovery, there is no download, no adb, no fastboot, the battery was removed, I charged it with a source of experiments and its voltage is correct, it was allowed to drain and retry after several months assuming the kernel is the one who tried to charge the battery by auto-restarting, and correcting itself, it was tested with every program found in Windows and Linux, and not gave signs of nothing.

win32

semc_device

win64

somc_device

linux

qhsusb_bulk

DEAD!! x_X

*this reminded me of the other device mentioned, qhdloader9008 or something like that, in addition to the qhsusb_bulk, it died with its stock-rom forcing shutdown with buttons because it frozen, among the few possible solutions found and tried, it is mentioned about another possible ported solution, It consists of something like making a copypaste of a complete image of all internal sectors and taking it to the sd-card, and I remember that it almost revived although something was missing and I no longer remember, I could try again but it did not work.

**I have hopes that someone with a lot of knowledge appears, a better solution or someone's help, using their image or helping me create one in some way or another, I do not know what else to do, maybe someone with it same model to try to boot from sdcard.

(I have never done it, if someone wanted to confirm, detail, or know how to provide the complete process, it would also be of great help. But according to what I "don't understand" is that the most reliable thing is to do it from a Linux environment and it would be something like for example )

dd if = /dirInput | vp | dd of = /dirOutput

and share it compressed?)

(If there is any private data, it reserves its right)

***From ignorance, I want to ask according to how little I have learned until today...

what happened here?

Was the recovery installed by mounting in cache? and was the data saved as temporary in a sector that is volatile not persistent? Wrong indexes were formatted and inserted into wrong sectors, losing access to gpt / mbr of all complete? or what happened here?)

****Something extreme and crazy out of context that I wonder, is the result of mixing mcu microcontroller, needles, wires, spi, i2c, bidirectional ttl converter, vcc, gnd, dat + dat- but I still don't understand much, to Unless they make it very easy for me to understand with kiss principles, boxes, apples and kittens.
