Canvas A1 - Please Help - unique problem

I have a canvas a1 AQ4501. Some days ago it just stopped working normally. When it turns on, I see the company logo with half screen turned yellow. Then it tries to restart but the same problem.
I have tried:
Using SP flash tools version 5.1524 but it goes into 2020 error while flashing, without battery. With battery phone is not detected.
Using twrp recovery to install cyanogenmod but it says partition had unexpected data after OTA update, something of this kind (did this using adb sideload)
The only thing that I can do with the phone is go into fastboot mode, recovery mode gets stuck on company logo. I can go to twrp recovery mode successfully.
I am using a windows 10 computer. Phone was on marshmallow when it last worked. I do not have an SD card. I have tried pressing both volume up and down with and without power button to flash using sp tool but phone is not detected bu sp flash tool in this case. I have tired meta mode (pressing volume up and power) here, phone is detected by sp flash tool but it goes into 2020 error BROM ERROR : S_BROM_CHKSUM16_MEM_RESULT_DIFF (2020).
Please help me as this phone is dear to me and has sentimental value.
Thanks for your time.

Bro give ur phone to MMX service center they will solve ur problem

Hard-bricked D855, don't get any fix to work

Hey guys,
I just bricked my D855 by flashing the wrong version of SuperSU (as if I never did it before). Now I don't have download mode, fastboot, recovery, nothing. So I tried these two fixes:
https://forum.xda-developers.com/lg-g3/general/fix-unbrick-lg-g3-stuck-qualcomm-hs-usb-t2933853
https://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
However, both tools don't seem to detect my device.
In the first case it says "Serial Port open FAILED.. TEST aborted!!"
The second tool just displays "Not Ready"
I see my device in the device manager listed as "Qualcomm HS-USB QDLoader 9008 (COM3)", so I don't really understand what to do anymore. Any help would be highly appreciated!
Edit: Ok, I figured out how to give BoardDiag access to my phone. However, now I get the error "Failed during loading flash programmer", so I still am not able to fix it. I'm really getting desperate
Edit2: Turns out that the provided BoardDiag versions weren't working. Got it to work with a different version and am now recovering my files

Try Install D85520i.zip from twrp recovery if you have twrp recovery mode boot working and flash
it worked for me my phone was hardbricked after installing some sound mod and then getting a bootloop
with phone booting but no sound after me deleting some sysytem files and then i deleted data cache and system dalvik cache internal storage every thing i tought it would be bricked forever

H815 Bootloop, No download mode, 9008 everything

For short, i bought the phone from the grey market so i have no warranty no nothing.
The phone bootlooped after 5min of use. I managed to get it up in the freezer and unlock the bootloader, installed stock 20C with the 1CPU active at boot mod. All went fine for 1 week untill the phone literally died while i was watching youtube. I managed to boot it in the freezer BUT i got 20~ seconds of bootloop then Demigod Kernel crash etc. green screen and Watch dog green screen.
I got my phone into download mode and started flashing 20C again but the phone bootlooped during the installation. After that the phone literally died (again, season 2 out of 10 xD). Back in the freezer... PC recognized it as QHSUSB_Bulk, i installed the qualcomm drivers and it appeared as Qualcomm HS-USB QDLoader 9008.
I tried QFIL with 1000000 files i've found on forums, all failed ofc.
I used Win32DiskImager to write"EMMC_ROM1_032G74_1803230737_00000000_20000000". The phone started to bootloop (at least it wasn't dead anymore) and bootloop in download mode. After few bootloops it dies and goes into Qualcomm HS-USB QDLoader 9008. Freezer or won't even turn on.
Then i used Win32DiskImager again to write system.img that i've extracted from my original KDZ (Europe H81520C_00_1218). The phone did almost the same thing BUT i've managed to flash the .tot file that locks the other 5 CPUs and the phone boots, "Android is installing 2 out of 31" or something then reboots into bootloop again. If i try LGUP with my original KDZ it reboots at like 27%~ during System phase or GPT Partition.
Any way i can recover from this endless bootlooping and 9008-ing? It's so cold in the freezer... i want to get it over with before i get sick xD

Up up

Up again maybe? No one?

[BRICK] Bootloop and no Fastboot

Hi all,
I've had this setup on my device :
Code:
ROM info :
ROM OS Version: 7.x Nougat
ROM Kernel: Linux 3.10.x
ROM Firmware Required: 4.21.40.xxx stock base
Based On: AOSP-CAF
SlimROM 7
Last monday, my phone was frozen on blackscreen, it didn't want to be unlocked...I tried to hard reboot but it didn't work, so I decided to open its back to remove battery.
After that it bootloop many times on this message :
"Your device has failed verification and may not work properly. Visit this link on another device: g.co/ABH Your device will boot in 5 seconds. Pressany key to pause boot."
There was no ASUS logo. But I'm use to see this message because I've flashed my phone several month before.
After many loop, I've finally access to fastboot, so I've done a wipe data factory reset, after I could access to TWRP. I've flashed my slimrom, but it didn't work, at next reboot, it was the same scenario : bootloop and no asus logo.
To explain my situation now, when i plug my phone, it vibrate and bootloop on message, after 4 - 5 loop I can see Asus logo and after, the dead droid. But after few minutes it bootloop again.
I follow instructions in this tuto : [Guide] Un-brick both (Soft/Hard) bricked Zenfone 2 ze550ml/ze551ml. , but my phone bootloop so i can see Moorefied in IntelSOC Driver during few minutes :
So i can't use xfstk downloader.. (because bootloop). The beautifulest thing is the buttons Vol UP Vol Down and Power not work ...
Any ideas ?
RIP ZE551ML :crying:
(I'm French, tell me if you don't understand me)

You are supposed to off your phone, start xfstk process then attach your phone

Sort of bricked G4, rebooting download mode, no fastboot recognition nor TWRP

Hi all,
I have tried my luck in two different threads already and did hours of research but thus far, no success. I hope somebody can help me.
I installed the official Nougat (V29A) update and after that the Oreo AOSCP ROM. Everything went (seemingly) fine, Oreo was working. I wanted to reflash Oreo to get rid of some Google Apps, but the problem then was, that I could not reboot into TWRP. The only recovery mode is the Android recovery and I cannot reset the phone, neither use ADB sideload, nor do anything else (unknown fs_filetype error). Only thing that is working, is to enter the fastboot mode, but my laptop does not recognize the phone while in fastboot mode.
I also tried resetting the phone to factory defaults from within Android (back when it was still booting up) and now my phone is stuck in a bootloop which ends in the (useless) Android recovery mode.
At first I thought reflashing the stock kdz would not be a problem. I am able to enter download mode, but it only stays in download mode for about 15 seconds and then reboots itself. LGUP or LG flash tool, don't recognize my phone in that short amount of time.
I tried the above mentioned solutions on OS X, Windows 7, Windows 10 as well as FWUL. No system recognizes my phone.
I really am at my wit's end. Any help would be appreciated.
If any further information are needed, I am happy to provide these.

I changed following in hidden menu NT Code, changed as below NT Codes with respect to firmware region... Rebooted after confirmation "NT Code Write OK" message.
V29a Firmware NT Code:
"1","FFF,FFF,FFFFFFFF,FFFFFFFF,11"
V20h Firmware NT Code:
"1","FFF,FFF,FFFFFFFF,FFFFFFFF,51"
Checked in both above firmwares..Worked flawlessly on my h818p...No more annoying message on every boot.
Software Version in about/ settings also changed to region exp. 20h-DS2-XX to 20h-ESA-XX upon reboot.
Is DS2 appears when cust mismatch..?
