Help! Homtom HT3 Pro - deadbricked

[emmes]

Hi,

first of all hello to the community, i hope somebody can help me with my problem!
i have a ht3 pro that was on official ROM V1.1.3. but this ROM is not downloadable on any site. As i wanted to install a custom ROM (KMDROID V1.0.6), i flashed die official ROM V.1.0.6. and me phone was initially bricked and the phone doesnt switch on any more.Stupid as i was, i didnt make any backup! Then i had some DRAM failures at SPFT but somehow i managed to flash official ROM V.1.1.2 but although it was successful at the SPFT it didnt boot either. Then i did another very stupid thing to flash the KMDROID 1.0.6. with the preloader of V1.1.2., and now i get this error: BROM Exception! ( BROM ERROR : S_STORAGE_NOT_MATCH (3182).

Right now i cant flash anything without this error. cant format auto or check EMMC in SPFT. So i guess i made to really brick my emmc/phone, maybe someone knows a cure.

My system is manjaro 16.06., SPFT 15.12, 1604, 1620 ..., i also deinstalled modemmanger (after that i was able to flash V.1.1.2), i also tried it on a windows system with the same 3182 error!

i cant format the phone, not even manual with hex code for preloader. Same Brom Error, Storage not match 3183. It seems that sp flash tool isnt recognising the phone at all, it always connects and disconnects every 2 seconds, it doesnt matter if battery is inserted after i clicked download, or without battery, tried some key combos, result stays the same.

Tried it on linux and win10 (mtk vcom drivers installed)

As i posted this problem in another forum, the moderator told me to ask someone to send me a backup for my phonel

i would really appreciate if someone would take the time to backup and send me his backup!

Probably we do not understand each other.
How do you plan to restore a backup if your pc (both Windows OS & Linux OS) doesn't recognize your phone ?
How do you plan to restore a backup if your phone doesn't boot in Fastboot mode ?

It is good. If you device full brick. This mean you finaly destroy GPT(GUID Partiton Table, EFI) and your device as before the FIRST SW download "at factory"(empty flash) BUT it must be define in PC DEV. MANAG. with pressing-holding some button(Vol + ; in my ht6, Win7x64) as MTK USB Port. We can't kill this never !
This brom com port , bootstrap "hartcoded" in SoC !
I have some troubles with Flash Tool SW download( and 16-year version also) and use Customer Download Tool SP_MDT_exe_v3.1620.00.00 (16-year)
Before generate file Checksum.ini - put CheckSum_Generate.exe in SW folder and run. In SP_MDT first press "Scan" and connect with THIS BUTTON holding it define number VCOM and BROM ports on this PC USB socket. IF OK disconnect phone, press "Start All" and connect with THIS BUTTON . After this my ht6 was flashed without any problem
You can find SW ht3 pro on Russian another forum and mainlly yours TWRP backup
Sorry for my pure English: I'm reader - not writer. Good luck !

There is no such unbrick method via META mode ! META = Mobile Engineering Testing Architecture for alive phones. And for what testpoint KCOL0( Keypad COlumn Line 0 ?? tp KCOL0 to gnd the same MTK USB Port in Device Manager.
For any unbricking actions you don't need disassemble phone !
