No lockscreen or power button options

I just got my T-Mobile Galaxy S II replaced today and when i turned it on for the first time, i noticed that it had no lockscreen, and no power button options. Instead, when u click the power button, it just shuts off the phone without warning. I am unrooted, nor have i ever been rooted on this phone. However i did take the SD card from my old rooted phone and put it in this one.. So maybe the rooted files have something to do with it. Im still not sure. If anyone has an answer it would be greatly appreciated. Thanks.

If you do a master reset without the SD card present in the device (keep it out of the device), do you still experience the issue?

Umm i will try that. But i have to backup everything first. Ill get back to you later on that

i have seen this happen on an SII when the efs folder gets deleted from the root directory.
the phone you got as a replacement must have been used before and the original owner had removed this folder.
it contains "as far as i've read" very important files that the phone needs and for some reason are not replaced even after a factory reset.
get another one if you can

Dang, this is my second replacement! I guess its onto the third.. Thanks though!

Define "factory reset". If you have truly reset all the software, then it must be hardware, in which case, time to visit a Sprint store.

Reset through recovery wiped everything 3 times

I was using Juice Defender and this was causing my reboot and unstalled it and reflash the MA7 return to stock Rom and my problems have been solved. In my case it was software or some tweak that I did that caused my problem. My phone has not restarted ever since this has been 5 hours.

Rooted Phone won't boot, can't access recovery or download mode.

Hello,
Today my phone randomly turned off by itself, and when I turned it back on, it got to the samsung screen and then went black. After I tried again/pulled the battery, it did the same thing. I can access recovery and download modes, but when I tried to restore my phone, my phone ****s off before the process can commence. Since the phone barely stays on for 5 seconds, I can't get Odin to see my phone. Please help. My phone is rooted, but I never installed a custom ROM. I'm still stock.

Try to pull the battery, then plug in the USB. You should be able to enter download mode without the restart.

Doesn't work. When I plug it in without the battery, the charging light comes on, then turns off, then the mini vibration happens. But I never get a samsung screen. Can't access download mode at all without the battery.

That did happen to me before. I'm trying to remember how I repaired it. When the battery is in, and turned on. Is it rebooting alot or stuck on the Samsung screen?

The samsung screen will come up, disappear, and then the phone doesn't do anything again. I have to pull the battery to get it to turn on again.

Have you had trouble with the USB staying connected with the PC before?

Not before this happened...

Hmm. I'm stumped. Sorry. I had the very same issue with my i777. I had the Odin screen on while I fiddled wth the USB connection at the phone until it finally stayed connected long enough to push a recovery to it. Although it doesn't appear you have the same issue. I figured I'd throw it out there. Again. I'm sorry I can't help further.

Not to my knowledge, I can still push it just fine.

There have been more than a few instances where someone would have similar issues where if would shut off after a few seconds. Most times it would reboot itself over and over, but for a few people it would just shut down.
Most of the cases I've seen, it turned out to be something keeping the button in contact causing it to trigger the switch.
Sometimes it was the button itself got jammed, others the button felt ok, maybe a bit loose, but under it it was essentially pushed in. A couple have apparently just had a bad switch or a short.
May or may not be the case here, but thought I'd go ahead and mention it.

What do you suggest doing if this is the problem?

Some people simply opened up the phone and reseated the button. Others had to buy a new button and replace themselves. Some sent it in to a repair shop to have it done for them and a couple who suspected it was an issue with a switch or a short on the board I don't think were ever able to fix it.
One guy got mad at his and slammed it on the table. After that he said it worked fine! I do NOT recommend this!!! But I have fixed stereos, VCR's, CD players, and all sorts of electronic equipment with this method! I would never attempt it with this fragile screen though!

What I recommend is that you go to a phone service centre that does JTAG, that way they can diagnose and repair the motherboard

I can't be so sure, but to me it sounds like the motherboard, if you have used triangle away before and have a clean flash counter you could send your device to Samsung for service and repair?

I was under the impression that Sudden Death couldn't happen to US variants and they they had fixed it in the updates, guess I was wrong. Gonna have my friend look at it, if he can't fix it i'll send it to T-Mobile.

when you try to access dl mode you get the option to continue or reboot, choose reboot and long press home and volume up, this will cause recovery to boot up (I sometimes have trouble getting it to boot with my problem without this method) then flash your rom again or flash a firmware package. this will at least get you into your rom for the time being. Then you can work from there.

did you try taking battery out for about a minute then putting back in and trying to boot to recovery?

Phone died - Very peculiar case

So last night I went to check my phone and it was off so I figured it had gone off on its own but upon trying to turn it on again I found that nothing was working. I plugged it in and got no response. Took out the battery, tried to boot to download mode, or reboot and have tried just about everything to be found online. I left it plugged in all night and nothing. I called samsung and their suggestion was to hold the power button pressed down for a few seconds so after that extremely well thought out suggestion didn't work they said that I'll have to take it in on monday as their service places here are closed during the weekends.
my problem is that I haven't backed up my info and I can't afford to lose it and they said that they will wipe it once they get their hands on it. I don't have a second battery to test but I just plugged it into my computer and it was recognized as a USB device. Nothing more, not what it is and doesn't show up anywhere and nothing has happened on the phone but at least it was recognized.
This is the most messed up issue I have every encountered and it happened entirely on its own. Im all stock and am running purely simple apps like viber and whatsapp and seriesguide and family guy. Its the most mild mannered phone and has the most messed up issue. Its like someone sucked the electricity from it. Please give me some ideas

You could probably enter download mode using an USB jig

It's a hardware thing that you can put in your USB port and bypass to download mode

[Q] Problem: smarphone won't unlock in the mornig

Hi, I got a problem and i can't come up to any solution.
I got a Note 3 Neo 2 day ago. As usually, i use my phone in the evening before go to sleep, then i attach it to the charger and that's it. I just get my phone in the morning, completely charged.
This phone, otherwise, won't unlock in the morning. Screen is black, whatever button Ii press it just dosn't light on. The notification led is flashing, but maybe it is just because i got a notification before it was locked. Alarms don't sound, and this is bad, and i have to take out the battery to restart it.
Any ideas?
Thanks

Do a factory reset and check. Also do not plug the phone in charger for long time..That is not good for phone, there are chances of brick.

Thanks, I posted the same question on an Italian Android forum and many users have the same issue: the phone want not wake up from deep sleep.
It seems to be the update of Google Play Service app: until the 5.9 version everything works fine, starting from the 6.1 version everyone has the same problem.
Probably Samsung/Google forced the update without checking if it was compatible.

In that case the phone is in charging state or not does not matter...That happens to some samsung phone but if you root and modify it..Should not be issue on stock

Itachi.. try a soft reset first before a hard reset and see if it works..
Sent from my SM-N750 using XDA Free mobile app

Personally I tried only soft reset, other people tried also hard reset, but none of those has solved anything.
One of them went to the store and he got a new phone thanks to this problem, but the new one has the same problem.
Someone has flashed the stock kitkat rom from United Arab Emirates and they had no problems at all.
I guess that upgrade to kitkat is the only solution.
