My Samsung Galaxy A20 won't startup suddenly. - Samsung Galaxy A20 Questions & Answers

Hi Guys,
Before this happened, my phone just kept on crashing randomly but today, after it crashed, it wont turn on anymore. I only got a black screen. I did search via google some way that might fix but none of them worked. I tried but hard reset or entering via recovery mode does not work. It will just vibrate and nothing happened. The samsung logo won't even appear. I also connecting my charger while doing hard reset but it does not work either.
So I tried other ways that involves a PC to help fix my phone and I found odin. I tried using Odin but it seems that it also does not work. Somehow, the odin and my pc detects my phone but it still does not work. Logs in odin is showing that my phone is "Added". On my pc, although my pc detects my phone (a sound pops up that it detects it) but it does not show up on my file explorer. When I look it up at device manager, it is listed under Portable USB Device > MTP USB Device.
Also, I tried opening up my phone but the LCD seems fine, I opened it up since I though that the connection for LCD is loose. But this does not work either. Now, I am out of Ideas on what to. Last resort is to take it a service center but I try to avoid doing such because I want to learn how to fix this.
Need help or advise on what to do.

Hmm there's a strong possibility that your LCD may be just completely dead. It vibrates and it's detected but it isn't showing anything. Can't really think of more than that.

Need help ;(

HI ! In the firsth place sorry for my bad english.
I have had a titan for about 6-7 months and a week ago it stopped working without a reason.
It stopped responding and after a reset it only shows the starting logo, and after that the screen slowly shifts to pure white colour and I can hear a one "beep" sound.
I tried to hard reset it and everything but without any luck. It charges the battery fine when connected to a USB port (orange light),
after turning it on i get the green ligh, main branded logo and some numbers (M05 S04 B06 D 3.60 and 2 lines of other numbers but they show only for like half a second and disappear so i cant write them down)
after that nothing, the logo screen goes all white, with some "notification" sound and thats all.
When connected to PC It gets detected as "something" and I cant use any flashing software because it says that it did not detect the device,
one time It got detected as some modem device. Is there any way to bring it back to life ? or is it bricked permanently ?
Please Help
And Thank You in Advance !!
Update: I managed to make a connection between my PDA and PC
it is detected as "Microsoft windows mobile adapter #2", and my PDA_PC is detected in My Computer,
but when I try to flash it the software detects it i get the message to wait 5 min till the flash is over but
as soon as this message appears my PDA is getting disconnected and i get an connection error...
help ;(
Ah... and one more thing, I dont know if it matters but when i open my PDAs memory the windows folder appears to be deleted...
can any one zip their windows folder and give me a link to it... maybe that will help ;(
I have the same problem on my Mogul with connecting to my Computer! For some odd reason it won't sync and restarts my computer automatically!! WEIRD!? Just go check out some of the Unbricking posts or Google it- they may help you!

my HD froze, hard reset not working

Hi all, first time poster long time browser I checked the wiki and did a search but couldn't find a similar post. Here goes..
Yesterday i tried to connect to this protected wifi at a coffeeshop, but my HD did not manage to connect even after entering the network password. In the end it froze. The home screen was showing, i could feel the vib when pressing the screen, but no action happened. I did a soft reset, but that didnt make a difference... nothing working still, while it is still trying to connect to wifi.
Then I first did one hard reset. I managed to get to the screen where i am asked to touch the screen in order to configure the device. While i could feel the vib, nothing happened. I did a second hard reset, ended up at the same screen, but this time there is no vib when pressing the screen... and still nothing is happening. Same situation when doing a third hard reset.
I am lost for ideas.... Have anyone of you ever experienced something similar and what did you do to resolve it? Or have anyone any suggestions as to what I should try next??
Very bad dude,
what you can do (i dont know if this will work).....Flash your original rom again. it is a kind of a hard reset, but maybe this will work.
can you boot to boatloader (three color screen), and see the text USB when connected to pc?
Hi Kadir,
thanks for your answer.
I am trying to flash my rom using the excellent tool Hard-SPL package from OliNex, but to no avail.... i keep getting error message 202 meaning that it can't connect with the device...
This may sound obvious, but just in case... have you tried to remove the battery when the device is turned off? Is the only way to ensure you are fully turning it off, in case you have some kind of 'static' acting up. I had a similar issue on a PDA and also in my notebook, and was solved by removing battery.
hi,
thanks for the advice. I wish this was all it took, but alas no, i am not that lucky. I am starting to think this is a hardware issue....
can you see the 3 color screen?(when phone is off push power on + volume down button and keep volume down pushed).
if yes can you see it you are now in the bootloader. just chech if you see text usb, this means its connected.
and then flash, no 202 anymore.
do not use hard spl if you want HTC to repair your phone(warranty issue)
Don't you have to disable USB connection in ActiveSync too? Or was that just me?
I found the Flash program killed active sync anyway, but you're right all the guides say to disable it.

HD not recognised on any PC

Hi Guys, hopefully someone can help me here it is driving me crazy - well, here is my issue.
Doesnt matter what PC I plug my HD into it doesnt get picked up, i looked in device manager and still nothing. Its like its not connected, but it shows on the phone that it is charging. And does charge.
Can someone please help?
Thanks!
Settings - Connection - USB to PC - uncheck 'enable advanced network functionality'
All that was there is ' Enable faster data synchronization '
No advanced network functionality. Im on Telstra NextG Network Australia with there crappy stock rom if that helps.
I'm looking at a stock Touch HD and you're right- they changed the name of the box. So uncheck 'enable faster data synchronization'.
I did but it is still not working.
I have also done a hard reset and restore to manufacturers default and still not working.
What kind of PC are you using? Is it XP? If so you need to download ActiveSync.
Using XP.. I have downloaded and installed Activesync. It used to be picked up on every pc and suddenly now it doesnt.
Opened Activesync ports in your firewall settings?
Yeah its all fine, its as though the PC doesnt even recognise it. Doesnt show up in Disk Management.
hi lucky
you're already the 3rd one with this problem.
if you plug-in the usb connector, is there a dialog popping up on your hd which let's you choose between synch or hd mode?
if not, welcome to the group of disapointed htc owners.
there is already a thread somewhere about this problem. i have exactly the same, but no one could help me until now.
at least i found a way to flash a rom. the usb connection was working for about 20 minutes. afterwards it broke down again...
try the following:
1. shut down hd
2. remove SD and Sim Card
3. plug in the usb cable
4. do a hard reset by holding vol up and vol down while you press the power button
5. confirm the hardware reset
6. when the hd is booting up again, it will do some kind of customization process. during this process active sync should come up on your pc. cancel the device setup in acive sync and wait until your hd is completely configured.
7. afterwards reconnect the usb cable and active sync should work for a while...
let me know if it helped. i'm still searching for a permanent solution for this problem...
Nope, didnt work at all.
Not even the choice to decide what I want to do pops up on the phone.
Do you think it could be a hardware fault?
I think it is a hardware fault because i did a SPL boot and instead of 'USB' showing in the white box "Serial" did.
It just seems wierd because it was working fine for 2 weeks and then it all the sudden stopped and I did no ROM flashing or anything.
Should I try reflashing my device through the SD card and see how I go from there?
did you try a different cable???
I have about 20 different USB -> mini USB and only about 2/3 of them work with phones !!!
Yeah ive tried all different cables, ive tried ones that work with my diamond but still dosent work with my hd.

Are you getting anything popping up in device manager when you plug it in, in other words does the list refresh like it has detected a new hardware device or is it completely silent? I have seen it a couple of times where a device gets stuck as being recognized as something else. If the list does scroll (responds to the HD being plugged in) do a screen shot of everything in DM then plug the HD in and compare the lists to see if it is showing up as something else. If so, delete the device then unplug and plug in the HD again and have it reinstall the driver.
Good luck,
Gordo
I did what you said Gordo, and it doesnt show up inDevice Manager. Its as though its not even plugged in but for some reason it still recharges off the USB.
I guess about the only other thing I can think of is to plug it in on another PC and see if that computer tries to load a driver. If it does then it is something strange with your computer. If it doesn't then there is something bad with the USB port on the HD (maybe).
Gordo
Yeah I tried that but still nothing, im sending it back to Telstra, since its within 14 days of me getting it I get a whole brand new one!
thanks for your help guys

S4 broken screen and Kies does not recognise phone

Hello All,
I recently had an accident with my phone and the screen broke into a 1000 pieces but is still together in the mobile.
I am trying to recover the pictures in the internal memory of the S4, and then the insurance will give me an exchange phone.
The problem I am currently having is one that I havnt been able to find on any post on any website, The screen is broke so the touch screen doesnt work, the start button seems to not be working or does work but nothing is shown on the screen or on the LCD light to indicate its on. I am trying to plug the phone into KIES 3, But the phone is not found/recognised so dosnt appear on the screen, I try to press the start button but nothing happens to make it recognise the phone. So seems Kies is a dead end here as it dosnt pick it up, and I also know that USB debugging is not enabled, as I found out by trying to use DR FONE FOR ANDROID, I manage to get to the 2nd option screen but says the USB debugging has to be enabled to work, but without being able to see the screen I cannot enable it. Is there any programme to view the phones screen on the laptop/computer and be able to access the system and enable the USB dbug?
I am currently downloading the ANDROID SOFTWARE DEVELOPMENT KIT as I read in some post, but will this resolve my problem or am I gonna hit a dead end???
I am hoping that the ROM/software of the computer hasnt broken or got corrupted as then the phone would be dead.....
Can someone please help me asap, as meanwhile I am without any phone till I am able to repair this one....
May I add that the PC dosnt recognsise it either, no new item appears in MY PC....
Mobile version is: GT-I9505 with the carrier being Orange Spain

[Q] S4 with cracked screen not recognized by Windows

Hi all,
I'm shocked to see how prone the Galaxy S4 is to screen cracking! 80-90% on googling "samsung cracked screen" or similar yields results about the S4. Wow..
Anyway, I'm not here to ask how to recover my data if my phone is pattern locked. I'd like to ask for some help in figuring out the weird behavior.
So, phone is/was locked with pattern, it's not registered with Samsung Find My Phone, digitizer+lcd are broken, USB Debugging is disabled. If I boot it up, the phone vibrates and I hear the samsung boot tune, and the LED briefly lights up. Also the menu buttons briefly light up. If I call myself, the phone rings and vibrates.
If I use the volume up / volume down buttons, the phone beeps for either of them but volume stays the same (seems like max volume).
If I connect the phone to my laptop, phone beeps and laptop tries to install a driver for "MTP USB Device", but it fails. Device Manager status is "The device cannot start. (Code 10)"
Kies does not recognize the phone, saying "This device is not supported by Kies. Make sure that your device is supported and try again".
Question is, is it possible something else got damaged when the phone 'involuntarily' hit the ground? It should've just got recognized by the laptop, and Kies should have reported I need to enter the pattern to unlock it (at least that's what it does for my S3 mini), no?
Would the digitizer/lcd not working affect something else within its OS?
I tried connecting my S3 mini's lcd to the S4, but the connectors don't match...duh.
anyone?

Maybe when I dropped it damaged the micro USB port as well, you could try a different pc first.
If another pc works try installing twrp recovery with odin then booting into the recovery, because it allows you to make file transfers when it's plugged into the pc
Reinstall the drivers. It's clearly a driver problem.
I've already tried it on a different computer and it does the same.
There is no driver to reinstall, it automatically installs it when I connect the phone.
I'm thinking it's due to the pattern lock. Can anyone with an S4 connect it to a computer and leave it locked. Does it try to install driver for "MTP USB Device"?
