My phone got Hardbricked while trying to reinstall the stock ROM from MSM tools. - OnePlus 7T Questions & Answers

I got a T-Mobile 7T that I converted to Global with the help of several guides in here, and everything was working ok. I rooted and flashed a custom kernel to OOS and was happy, but I wanted to try the new Android 11 update, but I wasn't sure if uninstalling Magisk and flashing the stock boot image would it be enough to flash the new update without issues, so I decided to flash the stock global ROM as clean as possible, and I used the MSM tools of the latest version: 10.0.16.HD65AA.
At the moment of putting the phone onto EDL mode and preparing to flash the stock ROM, I clicked start as my phone got recognized, but I ran into an error while flashing, which was saying something like "tgr id error" or something like that.
The phone turned off and bricked, I have no access to fastboot nor EDL, and the worst part is that now my PC doesn't recognize the phone now when I plug it in, so now I can't use othe MSM tool and try to flash stock again.

[Q] Can't use fastboot command suddenly

Before today, I have no problems with my phone and any other stuff, I have flashing & using almost every ROMs in the development section..
But suddenly, when I get into the fastboot mode to flash another kernel, it always stuck like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Tried using fastboot devices and other commands, they seem to work properly. All the flash & erase commands failed. using fastboot reboot-loader but no help.
What the worse thing is, I used flashtool to flash the stock .587 ftf package, so I have to use the stock ROM without Root now, and can't even change the kernel:crying:
Tried re-install all the drivers, still same problem. Google it but the only possible solution seems to be ---- try it on another PC, maybe it's the problem of my laptop's USBs.
I will try it on other PCs later, anyone have solution of the problem for now?
Thanks in advance...

It says relock then unlock could solve my problem.
But after relock, I can't even use the fastboot command to unlock the bootloader... still the failed(command write failed) problem...
try using flashtool. it may be the fastboot paths in your laptop have changed, flashtool should overcome that.

I cannot install a kernel and my IMEI goes null

Hi everyone
I need a serious help. I used Cyanogenmod 12 for a couple time and I want to return to my stock rom now. I install it via Odin and the phone starts normally. However, after the first reboot my IMEI goes null. Also when I try to install a kernel ( Agni pureStock ) Aroma Installer gives me

"lightbox_next": "Next",
"lightbox_previous": "Previous",

}
this error.
I don't know if it's related but I resetted my counter via Triangle Away, I resetted my CSC code and it returned to normal; none of them worked. Can someone help me please, what am I doing wrong ? At my first time, I could returned to stock rom from CM12 successfully and without an error.
edit.
I tried to install CM12 again, this time Aroma says: This package is for device: t03g,n7100; this device is t03gub.
My phone thinks it is a t3gub (what is that by the way ?) so I guess because of this it gives me those errors. How can I change it back to n7100-t03g ?
You have wrong recovery...flash twrp t03g version...not gub
Use any of these two.
Flash this through your current recovery (if its not Stock) (Recommended)
https://dl.twrp.me/t03g/twrp-2.8.6.0-t03g.zip.html
This you can flash through ODIN

did you find an answer for this problem.i also have the same problem
Yes I use adb with phone on fastboot mode and flashed a twrp and a new rom but it took me several attempts

Odin fails at "Custom Modem Binary", pulling my hair out here.

So I thought I'd relive a bit of nostalgia and I ordered a phone I used a lot back in 2012/2013, the Samsung Galaxy Ace 2 (GT-I8160), on eBay.
It arrived, but it was already rooted and was definitely sporting some custom rom. Seemed a bit odd. So I searched through my computer backups and found an Official 4.1.2 Stock Firmware for the I8160. Cool.... I'll just flash that with Odin.
NOPE.
When Odin gets to flashing the modem.img it fails, and on the device screen there's red writing saying "Custom Modem Binary !!". Weird. I decided that maybe this phone was from another region so I downloaded another official rom but it came up with the same error. i have now tried over 10 different region roms, including one for the I8160P. All failed. You can see on the device it clearly says "GT-I8160", so I really don't get where I'm going wrong.
I tried using emergency firmware recovery in Kies but it doesn't even recognise the device. Or at least it doesn't show up on the list of devices requiring firmware recovery.
Does anyone know what the hell I'm doing wrong?? It's almost as if I'm flashing the wrong device model. I'm stumped.
(PS. The 13 counts of custom firmwares in the image are from all the different roms I've tried to revive the device)

Realme x2 (rmx1993) hard brick, asking for help

hi, i'll try to be clear despite my english isn't so good. I unlocked/rooted and installed lineage without any issue, later i decided to rollback to stock, so i flashed thought twrp recovery the lastest original Ozip firmware, wipe format and...locked the bootloader. Well now started the struggle, my phone can't go in fastbot mode, bootloader mode or recovery, i can only go on EDL mode.
I read tons of guides, watched tutorial video about unbrick with QPST, EEMC DL TOOL, MsmDownloadTool and QFIL Tool, and despite i got my phone full recognized in widows on EDL mode, i can't flash anything becouse i need firehose programmer file ( mbn) and/or rawprogram file and patch0.xml
So i looked for em everywhere online with no luck, i read also any device with 730g snapdragon could work too. I tried also to decompress Ozip with 7zip but there is nothing uselfull inside.
Being days and no luck, i apprecciate any help and suggestions, thanks in advance
