Hi!
I have a problem with a galaxy a40 device, I flashed a stock ROM with Odin, everything went fine, green lights, PASS and all, but now the device just won't go pass the SM logo anymore. When I turn on, logo appears 2-3 secs I get a warning of the unlocked BL then logo comes back and after a second the phone restarts itself and the same goes on forever ( well about several hours, and after that it just shuts off somehow ). I cannot enter recovery mode or download mode at all. I keep pressing the combinations Power + Vol Down, Power + Vol Up, All three and every combinations I have just found on the internet so far. Odin doesnt recognize the phone, which is not a surprise since it won't start up. I have tried with adb but waiting for device is all I get.
How is it even possible that I cannot enter download mode at all? There was no problem with the physical keys, and the power still works, I cannot test the Vol buttons tho.
Has anyone ever had a problem like this? How can I come back from this? Is there a way to flash a ROM without download mode or turned off phone?
Thanks for any help!!
The download mode for this model is different from previous Samsung's :
IIRC, with the phone off, you need to hold VolumeUp and VolumeDown, then plug in the USB cable connected to a computer (you may need to press Power to power up the phone, I can't recall properly).
From there, you should be able to restore a stock ROM with Odin.
Let us know if it helped !

Here the same problem, have a40 in loop and never get rocgnized for computer, tryed many different cables, and installed a booring large amount of drivers software and nothing...
you need to power off device completely. let battery drain if you can't shut down. press and keep holding volume down + plug in usb cable for Odin3 (I doubt both?)

Generic answers, repeated 800 times why really need to waste a post with that? and that not was the problem:
1- For no usb recognition, is this phone bad design, in the back tap where is the battery in the samsung logo more or less if you push with fingers and charge is because the design of baterry is so crap and your usb port goes off when the under tap cable moves or just get little out of conection. If you can get working after push, usb on phone will do too.

dont kno if im posting this in the correct section or not but can some one plz help? i was trying to flash the stock files for my samsung vibrant with odin, but it froze so i unplugged and tried to reboot my phone but the phone to pc screen came up. ive tried holding the volume buttons + power to get back to download mode, but it just reboots and goes back to it, can anybody help?
Did you hold the power button down till it disappears and then release the power button immediately as it disappears?
hadnt tryin releasing the power button right away but i just tried and still no luck
Johnz is right. To make sure, unplug & plug back in the usb cable, then hold down the volume keys & power, wait till the screen flashes to black, then release power.
Unplug and pull the battery.
Install battery.
While holding both volume buttons, plug in usb cable.
Have odin ready to go, it seems to help. The phone should power up directly to download mode, once odin sees it, hit start.
i dont get what im doing wrong because ive tried what u guys said but after the screen flashes black when it comes back on its the phone to pc screen. ive also noticed that if i pull the battery while the usb cord is connected the phone stays on at that screen until i remove the usb cord, is that normal?
i just read that if the normal ways dont work that means ur phone is hardware locked. looks like im gonna have to try to send it back to tmobile and hope for the best
Try the above, but also hold the home key. I did the exact same as you, and this enabled me to get back to download mode, so I could Odin.
1) Remove battery, SIM, and sd card.
2) Plug in USB Cable.
3) Hold down Vol +/- as well as home.
4) Press power button for 2 seconds, then release.
This should get you into download mode. Then you can Odin back to whatever you were intending to do.
thanx for all the help guys but nothing seems to be working for me
Just throwing out an update incase anyone was wondering, I got my replacement phone yesterday and it turned out to be hardware locked as well. Tried to flash the fix for it and it failed and bricked my phone! So after calling tmobile they will be sending me another replacement and hopefully that one wont be locked as well
I had the same problem trying to get into Download Mode, I got into download mode and using ODIN tried to flash update. The process was stick for 10 min.
So I unplugged USB and got this phone to PC icon. All I had to do to fix it was to go into download mode again by holding both vol +/- keys and pressing power button until screen goes black then release the power button as soon as the screen went black. If you hold the button longer it will go into recovery mode. Then open ODIN again and re-connect USB and ODIN will detect COM port. However you have to make sure that all samsung usb drivers are installed. That is it. Then flash the update and you all set. The phone will reboot and you are back up and runing.

there is another way to this method, that works on any vibrant i've tried it on and also the captivates, had to help a friend restore his yesterday.
remove battery, sd and sim cards
plug in usb cable to pc and phone
hold down the volume buttons only
pop in the battery
if it comes up to the battery charging icon, pull the battery and put it back in again, should go right into download mode.
again, this works on any vibrant i've tried it on, and the captivate as well, good luck.

sorry was wrong.

Hi
did no work also
I am having the same problem, went to lg service centre, they could not enter download mode as well. I might need to change the circuit board for $321 singapore dollars..
Hi
i think you have to use this fix: http://forum.xda-developers.com/showthread.php?t=2582142
This happened to me,
Try holding the power and volume down hold until lg logo, let go and press and hold the volume down and power again, it should get you in recovery.
It might get you into a screen called "Factory hard reset" Agree using the power button, and it should take you to your recovery, and try flashing a ROM along with the Gapps (if you want, which I did) and then I used a recovery file after booting back into recovery to restore it to my previous state.
Good luck :good:
Shut down phone
From what I got from this, you're having problems shutting down your phone, correct? It keeps booting back up after the screen goes black? If this is the case, hold the power button (and don't let go) until it goes black, reboots itself, then goes black again. Shouldn't take more than 2 seconds after rebooting to shut down. Then, you can do volume up + USB to get into download mode.

Thanks for your help,it sorted out my problem! :good:
My phone abruptly turned off while I am using it under charge.
I promptly attempted to restart it through pressing the power button, but had absolutely no response.
Then I tried replacing the battery and the phone device on normally right away, with the Galaxy S4 logo shown as usual, but turns off after a second of the logo display.
Attempted getting into both the download and the recovery mode, no response.
Anybody know what's the issue here? Phone has been rotted and flashed with SlimBean ROM, it has no issues leading up to the event today. Please help!
Update: I tried accessing download and recovery mode as soon as I inserted battery into the phone.
It would have the loading screen as soon as the buttons are pressed, but the device still turns off after a second as usual.
Is it hard bricked?

Your s4s power button is fine?cuz my s4 doesn't power on with only inserting battery.try to put it on charge for 15 min. And then try to go download or recovery mode.if it does boot to recovery while charging then it will boot up normal.and make sure to use original charger and cable.

Hey, thanks for the reply.
Download or recovery mode doesn't happen when I try pressing the power buttons, however when I insert the battery while pressing the power+volume up button, the phone will go into those modes, but will turn off promptly in a few seconds.

Hi Guys!
I'm new to XDA developers, but I've been following this forum for many years.
I would like to resurrect my old phone, a Samsung Galaxy S4 Value Edition (GT-I9515), witch is most likely bricked.
About one year ago, the device started to randomly reboot, until it no longer powered on (It was NOT rooted or modded).
Recovery also did not work, so I decided to flash the stock firmware with Odin. The flash failed, so i decided to follow a (really stupid ) guide that said that to solve it was necessary to flash a PIT file of the Samsung GT-I9505, so I tried it.
Since then, I'm not able to boot the phone anymore.
What can I do with the phone now? What have I tried? I'll try to be as clear as possible:
Recovery mode:
I can boot into recovery only by pressing VOL UP + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Recovery Mode, 3 different things can happen:
It does not power on
It vibrates, then reboot and freeze in Samsung GT-I9515 logo
It vibrates randomly and then open successfully the stock recovery
Download mode:
I can boot into download only by pressing VOL DOWN + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Download Mode, it seems that the screen freeze at a certain point while loading the recovery mode warning (this warning loads slowly, like a slide from top to bottom). The device rarely fully load the warning, and when it does, when I press the VOL UP key to confirm entering download mode (sometimes it does not respond to VOL UP click for confirmation and i must reboot) Odin is able to find the device but during a flash the Odin log stop at Setup Connection, so the device is not responding.
Normal boot:
Yesterday, after hundreds of attempts, I was able to start the phone normally (I don't know how) , it asked for the initial configuration and language, but when I turned it off, the problem reappeared and I was not able to boot it normally. In most cases, the device freezes in Samsung GT-I9515 logo, it continues to restart or simply does not vibrate or power on.
When charging, I don't see anything such as the charging battery icon or the LED.
I realize that I was wrong to flash that PIT file, but is there anything I can do to make this device work properly?
Thank you in advance for your cooperation.
Noone?
Today, I was using my phone, and then it starting running really slow, so I decided to restart it. I powered it off like normal, but then when I went to try to turn it on, nothing happened. So I decided to plug it up, and that's when a screen came up saying the following message in red text on a black background:
Bootloader exception
[ AST_STAT = 0x10000 ]
Exception: do_handler_sync: DABT_EL1(esr: 0x96000010)
pc : 0x8f026210 lr : 0x8f0261cc sp : 0x8f117f60
I've tried looking up other solutions such as holding down power+home+Vol-up, and it does nothing. Holding down power button does nothing either.
Whenever I plug up my phone to my computer, it shows up as "SAMSUNG Mobile USB CDC Composite Device" in the device manager, but it doesn't show up as a drive like it normally would when I plug it into my computer.
My phone was also on android version 7.0 using the stock samsung ROM. I have never tried to root the phone either, so that shouldn't be an issue in this situation.
Does anybody know what I could do to try to fix this issue?
I would use Odin to flash a new bootloader or just a new ROM, but the problem is, I can't find any way to reboot the phone to boot it into download mode.
Haven't tried this since the s3, but maybe it'll work.

Hold power + volume down + home for 15 seconds. It's supposed to shut off from there and attempt to boot up, but if it's still getting stuck on that screen there may be a major hardware issue. USG jig wont work on S6 and S7 already tried before.
You can hold the combinations for longer until the phone reboots multiple times and you see the light blue screen prompting for confirmation to boot download (ODIN) mode.

The buttons seem to be unresponsive. No matter what combination I press, or how long I press, none of them do anything. The phone just stays on that screen until the battery dies. And as soon as I try to boot it back up or plug it into the computer after it dies, it just goes back to that screen.
Yours phone mbo is dead,try to rma phone.Emmc chip is dead on mbo,no flashing will bring him back to life.
