A20 bricked, can't enter download mode - Samsung Galaxy A20 Questions & Answers

1. Rooted using magisk after unlocking bootloader.
2. Flash this twrp using odin. https://drive.google.com/file/d/1Acfnf5yun09DPlCVUN47c51r_F7BnRx0/view?usp=sharing
3. Flashed this rom using twrp. https://sourceforge.net/projects/eurekaroms/files/Samsung/A20/R/pe/
4. Now phone is bricked and turns off after the samsung logo and I can't go into download mode using the "hold vol+, vol-, then plug into PC" combination.
I think the problem here might be because: I installed the latest samsung usb drivers on my pc but I didn't connect my phone to the PC after installing these new drivers, and maybe the phone needs to connect once to the PC so the PC can setup the drivers properly. But since I didn't do that before flashing the rom, maybe the that's why it can't go into download mode now.
Any solution?

Solved.
I got sick of it so I started holding volume +- and power button randomly during the boot loop, and it entered into twrp, and from there I booted into download mode.

[Q] stuck in cyanogenmod simple recovery, windows does not recognise device

Hi all,
I have a GT i9505 with cyanogenmod 11 installed.
I rebooted into recovery mode using the power menu option instead of the volume up + power + home option, which brought me into a cyanogenmod simple recovery mode. Soon I found my phone is stuck in this mode, pressing reboot phone only sends me back to this simple recovery mode.
I plugged my phone into my computer (that has kies installed), but windows 7 would only provide me with a "dee dee" noise and not able to detect my device.
I am quite frustrated now and don't know what to do. Do you guys have any suggestions?
Thanks in advance.

Have you tried entering Odin Mode (Power + Volume Down) and reflashing a custom recovery again?
If not, download Odin 3.07 (you will find it on Google), put your phone into Odin Mode (as I told you earlier), and download a recovery in .tar or .tar.md5 format. Put the file into PDA (or AP if you use a newer version of Odin on your PC) and press Start. Check ONLY Auto-Reboot and Reset Time and not Repartition or anything!. Then, it will flash again the custom recovery and you should be able to enter it using Power + Volume Up.
It may be a bootloader problem. Since it won't boot in anything else but recovery. I had a similar problem with an Galaxy S Advance and flashing a bootloader did the trick.
OMG Thanks Villa_Man!!! You guys rock!
one more thing if you guys don't mind.
When I pressed power + home + volume up, it will still take me to cyanogenmod simple recovery instead of cwm which I have installed.
I am currently booting into cwm via the cwm app. Is there a way that I can change my default recovery to cwm so I can boot into it via the hardware button method?
Cheers guys

please help! d802 bricked-no download mode. no recovery. not hardware factory reset

lost my twrp after installing bootloader changer and then installing kk bootloader(for cloudy 3.3). (accidently marked install twrp inside the bootloader installation after already having the latest twrp installed)
phone restarts right after logo appears and seems to be unable to boot at all.
no download mode. no recovery. not even hardware factory reset is accessible.
im really lost here ! read all xda posts nothing works because i cant connect to
the phone from any pc. please help! i cant flash anything because i have no adb or any connection from the phone to the pc.
wont show up in device manager in any way(with the latest drivers installed) and wont show up on linux on /dev/sd*.
before the bootloader i had access to twrp and showed up just fine on my win 7.
problem solved!
was able to enter recovery mode by pressing pwr + vol-up release when logo appears and press vol-up + vol-down.

I have had this issue multiple times with my A5. The first time it happened, I literally started to cry.........
Here's how you fix it:
If your phone is stuck somewhere, then hold the vol up + power buttons until the phone restarts
Skip the above step if you can boot your phone from a powered off state
Boot your phone into download mode by pressing vol down+ power buttons
Then open Odin and connect your phone. Your laptop should recognize it this time.
Then flash stock firmware for it.
Hit thanks if I helped

Hard brick

Hey their. So i jsut bought a one plus 6t and started playing around iwth it. I tried to get twrp and i got it but when i rebooted to os i had no wifi. So i download magisk zip and flashed it. After this i got stuck in bootloop and so i wne to twrp and wiped everything except system. Then i rebooted and got this message Qualcomm CrashDump Mode Attempted to kill init! exit code=0x0000000b do_exit. Then i freaked out and accidently wipes system too. Now i think i have a complete brick as adb still works but i cant transfer any file from pc to phone because theirs no system. Please help!!!
Never wipe system and vendor on A/B devices, literally, never.
Boot twrp and flash OOS or use msmdownloadtool.
What do you mean flash OOS. Like flash a fastboot file? And what version of msmdownloadtool should I get as their is no system. Should I get 10 cause that was my last system or it doesn't matter.
Update. I left twrp after flashing a stock image and now adb doesn't recognize my phone. When booting into recovery I go into the one plus recovery. Now I'm really screwed.
Okay now im really screwed. Whenever I boot with power up or power down I get sent to the bootlaoder page that says fastboot mode products name. I cant leave this page however. On the options above the information I click reboot recovery I get sent back to this page.
UPDATE. My phone is a literal brick now. It won't even turn on. I tried to force reboot it before and after it powered off it wont turn on. Its fully charged and when connecting to charger of holding buttons nothing happens. I have no warranty so Im hoping that someone can help me.
The "bootloader page" is fastboot and that's normal because there's no system to boot, you wiped that partition... and ADB only recognizes the phone when the boot process ends and ADB is enabled in the phone.
If you press vol up + down when you connect the usb cable the phone boots in EDL (Emergency Download Mode) mode, long press power + vol up to leave that state.
Now, download msmdownloadtool from here, extract the file, power off you phone, conect the usb cable to your pc, press vol up + down and connect the usb cable to the phone, open msmdownloadtool and flash the OS.
Edit: Read this thread for more detailed instructions.
What do you mean by flash the OS. The OS in the system or do I have to download one?
whenever I plug in my device it vibrates and then goes into the fastboot page. Also adb can detect it if I type in fastboot devices.
So i go the device to work and MsM worked until 4 seconds and then It said param preload for status of connection and status of last communication says device not match image
Try with the fastboot ROM.
When i downloaded another version of MsM it did not say no image match instead it stays at 4sec and says recording download time
Can you give me instructions on how to use the fastboot room? Like after i download it what should i do with it?
Download the rom, unpack it, boot your phone in fastboot (Power + vol up + vol down), connect the phone to your pc and execute the "flash-all.bat" file, and just wait.
um what is flash-all... How does it work what am i supposed to do.
what does unpack it mean?
Hey their im going to assume you meant to unzip the file and then open the file called falsh-all.bash. In that case when i do that i get this message "error: failed to load 'images.zip': No such file or directory
Press any key to exit..." In a CMD window

LG V35+ won't enter recovery mode

I bought the phone from AliExpress. I've tried holding all the keys in all the combinations and the phone just boots normally. I've run adb reboot bootloader, authorised access from the phone ,and it just reboots normally. I've just used LG UP to update the firmware to V350NO30d. Nothing has changed. Can anyone suggest a fix?
Additional: According to this page it's not the usual power & volume up combination. https://droidrecovery.com/lg-v35-thinq-recovery-mode/
You have to hold volume up and connect the USB cable. I tried the combination to get to download mode (volume down & connect USB) and that works. The bootloader/fastboot combination still didn't.
Update: The phone's bootloader is already unlocked. See screenshot. As I've already flashed new firmware to it using LG UP can I be sure there's not nasty spyware left on it? I wanted to do a full wipe using TWRP and return it to stock. Apparently TWRP isn't easy to use on this phone.
[RECOVERY] OrangeFox for LG V35 (judyp)
Requirements -LG V35 with unlocked bootloader -Android 10 (Oreo and Pie are untested) -A PC and ADB + Fastboot Download https://www.mediafire.com/folder/rd4o8mwzfg88i/Ofox Instruction 1. You need fastboot access. Erase the laf_a and laf_b...
forum.xda-developers.com
Follow this. Start by erasing laf_a and laf_b partition.
Ok, anyone having issue with phone not going to download mode or fastboot mode? Tried plugging usb cable with volume +/- nothing happens? Could it be because i flashed orange fox recovery? I feel its the only thing that this could happen tried flashing kdz by manually(kings tool) going to download mode but still not going to download mode when pressing volume buttons
