Replied with the conditions of use.

Understood, just let me know when/if you still want the recovery package.

I gave you a complete answer in the mail.

Files sent.  :)

Zhenja:
Hello. I apologize for the long reply. I was on a business trip.

I tried the recovery disk. It seems to be all according to the instructions, but the download process does not change in any way. As a result, nothing happens.

@tautech
Wrote a more detailed letter. Maybe I'm doing something wrong.

The problem is not solved. Who else has any thoughts?

tv84:
The .app file that you have in the scope is bad.

As you can see in the attached files, I made and ELF parsing to analyse possible errors.

My parser can't even parse your app file because it has errors inside.

00000000                 Magic: 7F454C46    ELF File OK
00000004                Format: 32-bits
00000005                  Data: Little endian
00000006               Version: 1
00000007                OS/ABI: System V (often set to this)
00000008           ABI Version: 0
00000010           Object Type: Executable
00000012       Instruction Set: ARM
00000014               Version: 1
00000018           Entry Point: 0000D260
0000001C  Program Header Table: 00000034
00000020  Section Header Table: 0081466C  <- for example, this is totally wrong as the file is less than 0x00420000 in size!
00000024                 Flags: 05000002
00000028           Header Size: 00000034
0000002A  Program Headers Size: 00000020
0000002C     # Program Headers: 8
0000002E  Section Headers Size: 00000028
00000030     # Section Headers: 42
00000032 SH String Table Index: 39

I think the file is wrongly loaded into memory because of the errors.

Since tautech's recovery was worthless, according to you, my suspicion is that you have a bad NAND.
