But your phone just connect with your phone by flashmode,not fastmode,you want to gonna fastmode,you need to shutdown your phone,and press VOL+,and then connect with your computer.Just do as what forumer said.Don't mixed.If you want to install the customer rom,you need to unlock your cellphone.Remember you need to go the following step:
1,root your phone,
2,unlock bootloader(fastmode)
3.install the recovery.(fastmode)
4install the kernel from the rom.(fastmode)
5install the rom.(recovery)
6reboot into the phone

power&VOL+ gonna fastmode,power&VOL- gonna flashmode.Seams the driver is different.If you unlocked the bootloader I think your fastmode driver is installed.And whatever of mode you went in,you must power down your phone.not restart.

I didn't get it but i tell you no response with any other buttons neither vol- or power on by itself
I only wait while charging till sony logo appears by itself without pressing buttons then i try everything and the only positive response i get is :
as i told you ( power & vol + ) ----> goes into flash,mode !!!

[Q] Not booting samsung galaxy tab 3

hello all,
if tried to root my Samsung Galaxy Tab 3 using this tuturial:
http://forum.xda-developers.com/showthread.php?t=2531784
but because i had some problems putting the file in the tabs memory i switched to another tuturial afther step 5 (so yes i did use that file that i had to put in odin)
afther that i stept to the tuturial from this site:
http://androidxda.com/root-samsung-galaxy-tab-3-10-1-gt-p5210
cause i only had to use an file that i can put in odin.
it worked perfectly but when it should of rebooted automaticly it didnt.
so if searched on google came to ur site again and found out that there was an problem with rebooting. the defices where not able to turn of and had to wait till the battery died then recharge and it worked. but my problem is slightly different so im out of answeres.
my problem is that the tab wont go further than the screen wich says Samsung GALAZY TAB 3 so mine does not compleately start up.
if tried to press down power button and volume down button for 5 secs then relese volume down button and hold power for 5 secs longer
also tried power down button for about 10 secs to reboot.
and tab screen and power button for 10 secs
so since that didnt work i tried to get back into the download menu or the recovery menu but since it wont go further than the Samsung GALAXY TAB 3 screen i also cant come there. so my pc and odin also do not find my tab.
does someone please please have an sollution for this :crying:
EDIT: well if figured out that this is a brick and might of found the sollution on ur site:
http://forum.xda-developers.com/showthread.php?t=2604681
but i cant use this sollution aslong as the tab wont connect to the pc. so could anyone please please tell me how i can get into the download mode screen ?

to get download mode you must press and hold the Home + Volume Down + Power buttons simultaneously for 3 to 5 seconds until you see the warning screen.

no it doesn't have a home button , and nothing will stop it , what i noticed tho that if i hold vol down and the power button the next time the logo will disappear way faster but only once each hold and ill get a delay of 2 seconds before that logo appearing again and the phone rebooting , its been literally 62 hours since it started doing this , it started with a battery fully charged meaning a 5000ma , about that delay i tried using it but nothing worked , i tried clicking vol up and power button which is supposed to put the phone in recovery mode but nothing happens , i went as far as spamming random buttons to holding them for more than a minute , nothing stops it

Then you hard bricked your device, sorry to tell you that. Take it to a service, and see if they can do anything to it, but you most surely bricked the hell out of your device, up to the point of no return.

If you want to boot into download mode try this:
When you see Samsung logo immediately press volume up + down and while holding connect the phone to PC using Type-C.

Download mode not open for me :crying: :crying: :crying:

If you are stuck on Samsung Logo, connect to PC and press Vol Down + Power for 7 seconds. It will go to charge mode. Disconnect from PC and it will power off automatically. After that press Volume Up + Down and connect to PC while holding and you will enter download mode. It will ask for confirmation.

Useful. Works

Thank you for this post. I did this and my phone booted to TWRP. (I was flashing TWRP when I encountered the bootloop)
After booting to TWRP, I did an advanced wipe (I left System unchecked). After the wipe, the phone booted normally.

Cool. TWRP for Android 10 came for M305F, and I am on GSI now.

Phone bricked, no download mode, can't recover

So, as the title says. My phone decided to do a little update through OTA. All fine, all good.
However, during the update it suddenly switched off and rebooted. Then a nice screen popped up with the ominous message: "An error has occurred while updating the device software. Use smart switch to restore the firmware". Great!
So, hooked up the phone to that app, but it says unsupported device. The emergency recovery list also remains empty. Thus, a little Google-fu later and it seemed I could also do it with Odin. I know Odin, so no problem.
Downloaded the latest firmware with Frija, extracted, loaded into Odin. Then, I tried to enter download mode by holding vol up+down while plugging in the device. No dice, still the error message. Tried it countless times with different timings, but it simply will >not< enter download mode.
I cannot turn the phone off either. Anyone knows what to do? All stores are closed for the next 2 months due to Corona so I have no phone at the moment.

ohhhhh wait to open samsung store to fix

power button & volume - for 7 secs , release when it vibrates , and immediately power button ( for 1 sec and release ) & volume + ( keep pressed ) , to get into recovery
From recovery there is an option to get into download mode
Requires perfect timing , yes ! but you will get it right
Cheers

The buttom combos do no longer work. It seems there is no download mode or recovery anymore.
Anyway, the phone now completely died on me so I have to sent it in for repairs. It will no longer even charge or turn on anymore.

I'm having the same problem. Ugh. Can't get into recovery mode

To go into download mode at least on the n975u model you turn off the phone then hold volume up and down and insert the usb cable. It should boot into the download mode.

here is the solution
keep it running to empty out the battery
make sure its dead by powering up ur device
if u r sure its dead, keep pressing the combo and connect u r device to pc.
congrats,

And from there i think if you plug it in to odin you will find that the phone is still in download mode despite not showing the correct screen. Ive flashed firmware before with the triangle warning screen on instead of download mode, it works fine. So long as there is a blue indicator showing in odin then you can flash the device.

This is the actual answer. The error that op originally got is still in fact download mode.

My brother you saved my life thank you

To anyone coming across this thread, I had the same issue as OP. Bought a "new" Galaxy S10e SM-G970F which turned out to be SM-G970N. Everything worked except updates, but I managed to flash the latest version through ODIN.
A few months later, when I tried to flash a new version, the ODIN transfer stopped mid-way and the phone rebooted to a lightblue screen with korean letters and "Smart Switch" written in English. However, Smart Switch declared that the model is not supported for reinitialization.
I tried to reach download mode somehow, as the phone could not be turned off using a key combination or via PC at this state. What @GeeAyeZee and @pcriz said is absolutely correct, THIS SCREEN IS INDEED CONSIDERED DOWNLOAD MODE.
I persisted with ODIN, trying to flash the new version 2-3 more times (rebooting the phone and PC between attempts) until eventually the process completed! Phone is unbricked. Hope this helps someone.

Need help plz !!!

Hi frnds.
I have a Samsung galaxy j2 (sm-j200g)
I unlocked bootloader and installed twrp.
But I can't slide the twrp button due to screen issues so twrp is useless in current situation.
Currently the phone has no system OS and I want to restore the stock firmware.
But I'm unable to boot into Download mode (it just boot by luck in rare situation).
The phone is not even charging correctly now. It shows the battery icon for 2-3 seconds and then screen disappears. The same happens when it accidentally boot in download mode.

The battery icon doesn't even show any color.
The phone turn on but only for a few seconds.
Help plz.. Thanks.

you can use 3 buttons: volume down+ home + power to go to odin mode
then use odin to flash
