[Solved] Can't enter Download mode in Samsung A90 - General Questions and Answers

Post resolved, turned out that phone was a fake chinese one. No way to unbrick it as there is no known OS to flash it.
--------------------------
Ok, some backstory a friend brought this phone from Peru to Argentina (so I'm assuming it's a SM-A908B global version), seems network wasn't working, so someone tried to "fix" it and sort of bricked it. I said, ok give it to me and I'll just flash an official firmware to bring it back to life. But I can't enter download mode.
-Phone turns on but it's stuck in logo screen (I noticed from some videos that their phone has a 5G after A90)

-Turning it off and pressing volume up + volume down and putting usb cable goes to "Factory" (This also happens when powering off and powering on with volume down + power button)

-Volume up + power button goes to this:

Then you can access fastboot and recovery mode
Spoiler
-From recovery menu, "reboot to bootloader" takes you to fastboot, so it's the same as the second option from the previous menu.
-Bonus image from "root integrity check" where we can see that previous person tried to change IMEI and ****ed up
Spoiler
So far I tried:
-A basic wipe data/factory reset, but obviously it didn't work.
-Extracting recovery.img from AP_A908BXXU4CTL3_CL20174301_QB36568574_REV00_user_low_ship_MULTI_CERT_meta_OS10.tar (and extracting from lz4) and flashing it via fastboot, but it fails as it says it doesn't have permission to flash recovery.
-The same with System.img extracted from the AP file, but fastboot flash just fails (I could try to do this via adb in recovery, but I would like a second opinion here).
Any help would be very welcomed. How to get access to download mode to flash an official firmware, or how to flash a odin firmware via recovery mode (I tried searching for this but couldn't find much).

What happened for this to report modified file ??

Are you asking about the log of "root integrity check"? I don't know what the previous person tried to do with the phone, probably tried to root it and failed. Looks like some system files were modified

@Zero.G
Use Samsung ODIN to fix phone.

ROM install failed

Hi,
I was trying to install a ROM this was my very first time I never did this before. I started ODin, attached my phone in download mode, provided .tar file in PDA and clicked START. A few command ran in ODin console and then my phone display was gone and nothing further happened in ODin console. I waited for long but no progress. I detached my phone and tried to restart it in order to revert back to my previous ROM. But I am seeing only this screen and I am stuck here:

I was installing ROM from this thread:
http://forum.xda-developers.com/showthread.php?t=843019
I was following these steps provided on another thread:
Instructions - ODIN (long)
- Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
- Unzip the attached CF-Root-xxx-vX.X.zip
- (USB) Disconnect your phone from your computer
- Start ODIN
- Click the PDA button, and select CF-Root-xxx-vX.X.tar
- Put your phone in download mode
- (USB) Connect the phone to your computer
- Make sure repartition is NOT checked
- Click the START button
- Wait for the phone to reboot
- Done (if it took you more than 30 seconds, you need practise!)​
flash oficcial rom with odin 2.3.3 2.3.4
and then go to recovery mod (home key+power button) then click install zip form sd card and then pick that rom and then do factory reset and wipe cache reset
and then reboot
Hi mv_style,
I tried flashing official rom with odin. Everything ran successfully in oDin. But when I rebooted my phone it shows the start screen and then restarts and this repeats infinitely.
Can you please let me know whats the problem and how can I fix it?
Thank
Did you try reflashing it again, after factory reset and wipe?
Ok press Power buttom + Home buttom and select wipe data factory reset and than reboot the phone.
Install clockworkmod and wipe all ...it wuold be the solution

[Q] Help with my Android Phone

About the phone:
1. I dont know the exact phone model, but it is Cloudfone Ice plus. There is a phone called Cloudefone Ice (Huwawei u8500) but i dont know if mine has another name.
2. It looks like this,
h++p://cdn2.sulitstatic.com/images/2012/0926/222830332_22162996997ba02ceb979675b8093b33516b3b725d6504ce0.jpg
3. Adroid version 2.2.1
4. Detected as "Globe Phone" in Google Play Market. *Globe is a carrier in our country.
The Problem:
When I turn it on, the android logo appears, and stays like that forever.
Cause:
After I tried to install a custom ROM using update.zip in recovery mode, the process got aborted in the last part of the installation.
5. I'm not sure if it's fully rooted, I have superuser but when I tried Root Checker before, it's not.
Other info,
I already tried to boot in recovery mode(it's the only mode that I get into now), I wiped data and cache/factory reset.(still stuck on boot screen)
I tried to install other Roms(update.zip), but all gets aborted in the beginning
I tried to download an update.app file in a dload folder in the root of sd card(firmware for huwawei)- I can't go to update firmware.I can only go to recovery mode.
I tried adb, I can use adb devices, it shows MT(serial number)
adb shell shows adb shell exec '/system/bin/sh' failed: no such file or directory exists
superboot cant detect the device.
I boot the device using power button+volume up,
when I use power+volume down, android logo appears and "Factory Mode" in the lower left (then It stays there forever, whatever button i press)
These are the infos that I can give, please help, I'm looking for fixes since yesterday from google and forums but no luck, nothing works so I decided to post my own.

Short the points point here and plug the USB cable.
I use a touch screen stylus pen to short those points.
Your phone should be turned on and in Download Mode.
I don’t what is the function of those points. I think the EDL pin/ test points maybe are located at there. Therefore, the phone will enter EDL mode when the phone is booted with the shorted pins.​2. Flashing the old version firmware(M631Y_02.10.00RDD_HK.00) with QFIL
3. Enter Fastboot Mode and boot to TWRP
Code:
fastboot boot TWRP-3.2.3-TwrpBuilder-m631y-2018-09-06_09-50.img
4. Install TWRP
If you don’t mind using a development version of ROM, then finish. If you mind, continue to install a newer version of ROM.
The version to install here is CMA1S 02.23 HK. The latest version for CMA1s HK edition should be 02.25. I tried install 02.25 and 02.24, but it seems that both cannot work with the older version of Boot and ABoot.
Install update.zip using TWRP
Install downgradeto210All.zip. This will downgrade the firmware and Boot back to version 02.10
Install upgradeto223modem.zip to upgrade the Modem back to 02.23.
Install TWRP again
Below are the suggestions for deleting the useless/infected system app preloaded. Please mount the system partition with write permission in TWRP. Delete the folder mentioned.
Infected stock camera
/system/vendor/app/QuanNengCamera
CMHK apps

Do you want to be able to modify your system partition(including rooting the device) at some point in the future? If so, check the box beside the "never show this screen during boot again" then just swipe the slider at the bottom to allow modifications in the future.
Or
If you do not plan to modify your system partition in any kind of way, tap the "keep read only" button.
This happened to me multiple times, for me it was an error with flashing Treble GSI from google, tho i fixed it by going in fastboot mode/bootloader and on my PC to flash boot, lk, lk2, recovery (official one) and then reboot my phone, but you will delete the TWRP Recovery just so you know.
_________________________________________________________________________________________________________________________
NOTE: I don't know if this will work for you and might brick your device if you don't use correct ROM files...
_________________________________________________________________________________________________________________________
Also if it then boots into Fastboot mode than you can try flashing all files (It will factory reset your phone)
You have to install adb and fastboot on your PC
Commands:
cd *the path to adb and fastboot*
fastboot devices
fastboot flash *what you wanna flash* *filename of the file that you wanna flash*
For Example if you wanna flash boot it will be like ( fastboot flash boot boot.img ) if the filename is with .bin wich most new devices use it will be fastboot flash boot boot.bin
Hope that this helps

Would be happy if someone can help me find a Solution i searched already the last 15 hours.
(p.s Sorry for my bad English)
it seems that the bootloader is locked, you should unlock it to be able to flash custom rom, like the samsung rom.
View attachment 5662231 it says "Custom binary blocked by OEM lock".
Try to see if he installed a custom recovery like TWPR, but 90% the phone doesn't has a recovery.
try to unlock the bootloader by entering fast-boot mode.
>Now turn off your device completely.
>Press and hold the Volume UP and DOWN button on your Galaxy A32 and connect it to your PC
>This will boot your device into Download Mode.
>Once in the Download/Recovery menu, press and hold the Volume Up key until you can see the “Unlock Bootloader” >screen.
-Unlock your bootloader.
-Download A32 5G: a32x.
-Put the TWRP TAR for your device with Odin in the AP slot.
-vbmeta_disabled_R.tar in USERDATA slot and click start.
-Start flashing the recovery.
-Then enter onto the custom recovery.
-"Wipe"-->"Format Data"
-Install custom rom !!make sure to have the stock kernel,vendor!!
