Hello everyone, my a21 (SM-A215U) can not go into download mode with the key combinations (volume+, volume - and power) and does not display anything when it is plugged in. I have tried everything and nothing when I plug it in on the computer it makes constant noises (like connecting and disconnecting) and displays **MTK65xx preloader** at each connection which can last only a few seconds. Does this mean that it is in soft brick or hard brick. Please help me to fix it

Well I flashed it using odin, but unfortunately it died. It does not turn on, even in charge nothing is displayed on the screen

Maybe, but I don't know to what extent because the key combinations no longer work so I can't enter download mode. The battery is in good condition

.....So, I would like to know if there is a way or trick to be able to put it in download mode so that I can flash it with odin or if there is an application that I can install on my PC to repair it.

Hello everyone, I think you can all be busy with your business, but can someone help me out of this horrible situation because I no longer have a phone to work.

Cordially

Hello

After some manipulations, the only sign of life and hope that I have is when I plug it into my computer it now displays: **MediaTeK preloader usb Vcom (Android)(com)** it always does constant noises (like connecting and disconnecting) the connection can last only a few seconds.
So I am still unable to put it in download mode via key combinations. What are the possible ways to enter download mode? or at least force it.
Do I have a small chance that it will be repaired.

Thank you

Bests Regards

Hello,
While I'm waiting for your advice to repair my galaxy a21 sm-215u, please I need stock rom / firmware with MT6765_Android_scatter for Samsung galaxy a21 Chipset 64bits - MediaTek Helio P35 (MT6765), because I can’t go into download mode with the key combinations (volume+, volume - and power) for flash by odin. I would like to try fix it with SP Flash tool.

Thanks to all

Hello everyone,

Maybe you are all busy with your activities, but I noticed that no one has reacted to the case of my a21, sure that there is no other solution than threw it in the trash. Please share with any tips or possible ways to help me fix it.

I'm really in trouble

I actually just did this myself the other day i had 2 A215u one was android 11 and frp locked and one was android 10 and unlocked while trying to root the one on android 10 it went black no response to anything plug it in to the computer it shows up as mt6765 preloader. And it just continuously connects and disconnects in device manager ive been trying to get sp flashtools to get it back to life because odin cant find it and im at a loss so im stick with the frp locked one which i cant get unlocked for the life of me even though I just FRP unlocked one a couple weeks ago but I think it might have been running Android 10 and not 11 I don't remember so I have no solution for you but I'm along for the ride

Hello everyone,

I am looking for a website where I can download: SM-A215U(DSH) A215USQU5AUI1/A215UOYN5AUI1/A215USQU5AUI1 for free.

I must tell you that I have tried several means but the only two that give me hope are the SP Flash Tool and the SWD AfterSales Tool. And both give me the same errors. For the SWD AfterSales Toolc is: Connecting to brom failed STATUS_SEC_AUTH_FILE_NEEDED and for SP Flash Tool: STATUS_SEC_AUTH_FILE_NEEDED (0xC0030012) and when I used bypass utility it is: BROM ERROR: STATUS_SEC_IMG_TYPE_MISMATCH (0xc002002A) or STATUS_SEC_IMG_TOO_LARGE (0xC0020005) everything depends on the manipulations I have carried out. The only region I haven't tried is DSH, I try all the others such as: BST, CHA, TMK, VZW, SPR, etc...

Thanks to all

Bests regards

Hello everyone,

Especially LR7875, thank you for the link but unfortunately I could not find region DSH, OS 10 for version A215USQU5AUI1. See photo below. Therefore is it possible to find a MT6765_Android_scatter.txt for Samsung Galaxy A21 (SM-A215U) (DSH) A215USQU5AUI1/A215UOYN5AUI1/A215USQU5AUI1 OS version: 10 in your hands.

What if you flash a wrong version? Will it brick it even more?

    Hello everyone,

    I tried a complete flash with Nand Erase and Re-Partition
    1/ I extracted the .PIT file from the official rom (it is in the CSC file) using 7-ZIP
    2/ I enter the AP, BL, CP and CSC in Odin
    3/ In the Odin options I check Nand Erase and Re-Partition
    4/ In the "Pit" tab on Odin I insert my pit file
    5/ I launch the flash

    It's like magic , it's ok for me, the phone is on, but I have another problem with the imei which is unknown(0000000000000) so I can't make calls. What to do to fix this problem.

    Ps: I tried to root the phone via kingroot arrived at 50% it failed and kingoroot at 90% failed too
    1
    Tomorrow I will post all the information on imei recovery
