Just read the post, can not think of a subject, Android and impossible would fit

[myster1086]

Ok I've already read everywhere that it's hard, need special equipment, bla bla bla.
I don't want the hurdles, I want info. If it can be done, it will.
I have, or had, a Motorola E5 plus. The phone was not encrypted or anything stock. It was rooted, bootloader unlocked, bricked twice, yet my everyday phone. Until tragedy struck, and by tragedy I mean the right fall at the right time, snapped the screen in half. Ok main and sub board (main is well main, sub was USB connection) survived, all but screen and battery. The connection between usb and main board was also damaged.
So I have the main board. It's qualcom. I need 2 small, like 50kb, files off the internal memory. I would like, please don't reply if you are going to say it's hard, impossible, unlikely...
Whatever it maybe, unless it's what wire soldered to what pad connected to usb would give me 1 of 3 results.
1. Acts like phone never had such bloody end, and connects to PC
2. I can get it to boot to twrp, and dump the files
3. I get the files.
To be honest and some will find this childish, I have a very old account on a game that I've been playing for almost 4 years, day 1 account. I cannot lose this account.
Please keep it only to what I can do, I'll upload the main board in a few moments as well.
Thanks guys

Hi,

You can give it a go with buying some spare parts from Ali or so,
I saw USB for a few dollar and if needed a replacement screen for less than 20.
Put it together on your workbench and try to connect with a USB cable and make backup.

good luck.

Unsolder internal memory chip and read the contents with proper adapter. There are cheap options like wiring it to usb sd card reader or more expensive, you will decide. But it's doable...

I think that I'd give it a go trying to get the USB working.
I don't know if the USB connector board is totally passive (at least for the USB).
Are you sure that there is a problem with the USB and not that it's not booting at all?
Current measurements are helpful on a totally opaque device.

I have an E4 with a broken screen, no problem.
You just use "screencap" and "input tap" over ADB to get anything done.

You really didn't try very hard on the subject.

How about "need help recovering data from broken Android phone"?

Honestly, would you still have clicked into here if the subject was that? I think he put quite some effort into the perfect click bait title.

In any case, the damage is done, and chances of recovery are slim.
I mean seriously, WTF happened to this board?

Buy another phone, same model. Then transfer the memory chips to it.
If you don't work with BGA normally then you better practice a whole lot first.

I'd definitely try powering it on and access via USB before going down the path of desoldering things, since that will make it much harder or even impossible if you mess up. If the data is worth more than you're willing to risk (and if you haven't desoldered a BGA before, then this isn't a good idea to be your first time on) ask a data recovery company to do it.

Try googling “android data forensics”.  Cops and spooks get this type of data recovery done all the time.

AIUI the phone ships with Android 8.0. This means it is encrypted.

The processor is a Qualcomm MSM8940 and the memory is an H9TQ26ADFTBCUR-KUM eMMC + DDR2 combo chip.

I don't know whether the processor and eMMC are paired. If they are, then you would need to transfer both to a replacement PCB.

I don't know how encryption is implemented in this phone, but my understanding is that all the data are encrypted, irrespective of whether a password has been set. In this case the unique security key is known and accessible to the OS, so it is able to decrypt the data. When you set a password, the original key is encrypted. This encrypted key is then stored somewhere, and the original key is discarded.

The following test reports identify the memory chip's capacity as 32GB:

https://fccid.io/O57TB8504F/Test-Report/Test-Report-3373944.pdf

ISTM that you might be able to access the eMMC by identifying its power requirements and its eMMC interface pins. Then you should be able to build or buy a jig to access it as an MMC or SD card. However, the data will most probably be encrypted, so it may turn out to be a wasted exercise.

The following discussion doesn't hold out much hope for you:
