[Q]Galaxy S2 i9100 keeps rebooting on standby - Galaxy S II Q&A, Help & Troubleshooting

Hello, yesterday I cleared some cache using some app called "App Cache Cleaner - 1 Tap Clean" because my Dad's phone was low on storage, and it cleaned allright and then I umnounted the 2GB SD Card and then rebooted the phone. I don't know if this could be the cause, but ever since I did it the phone always reboots when the phone autolocks (or someone locks it). Sometimes it even reboots and stays black (note when someone calls you don't get a message that the subscriber is offline, it keeps ringing!) and then I have to hold the power button long enough for the phone ro reboot...
I removed the SD Card, tried factory reset, but nothing seems to work. The phone was never rooted or with a different ROM than the officials,. so I honestly have no idea why it keeps rebooting and doing stuff like that. It's on the latest available Android firmware -- 4.1.2.
What can I do to fix it?

Clean battery contacts with isopropyl alcohol, then try replace battery, then replace USB board/port - which is a relatively easy fix to do yourself for around 10 bucks (if you pay someone else to do it, labour could easily take this up to $70/80 or even more depending on labour costs in your country). If you decide to do this, KeithRoss39 has a guide in the General section (search for 'replacing USB charger board') that has all the info you need to get it done.
The other thing you could try before replacing the USB board is to flash stock firmware manually with Odin/in download mode (assuming you haven't already done this/the updates you've done up until now have been via Kies).
If I had to bet money though. I'd be wagering the battery (particularly if it's getting on age-wise) or the USB board (which is a common fault with Samsung phones).

Seriously, that is the only thing to do? I mean, it was okay yesterday and this suddenly hapenned... How can I be sure that it's from the USB Charger Board? And also, the phone won't reboot while I'm using it, but as soon as I lock it and wait a while, it reboots. I just tried wiping the phone again, and it even does that on the setup screen at the beginning... :crying:

Okay, I flashed a stock rom with Odin, as suggested, but it's doing the same thing... Now it's even worse! When I push the lock button when the phone is on, the phone freezes immediately and you can hear the lock sound looping over and over and over again. I have to hold the lock/power button for the phone to reboot... but it does that every time. Even when I don't press the lock/power button, only leave it to lock on its own, it does it again. It charges the battery just fine, I recharged it last night and it has 100% baterry... what could this be?

Did I just brick my GS2?

Hi guys,
Very confused here!
I was running the latest AOKP Hydrogen rom and one of the latest Siyah kernels...
I recently moved onto the S3, so I was basically prepping my S2 to be sold. What happened was as follows:
I had my S2 connected to my PC to get some data off of it;
I went into the factory reset menu and it froze so I unplugged the USB cable (I assume it was waiting for the SD card to become available.
It displays the "settings is not responding. Would you like to close?" message, but I clicked wait and it seemed to work fine as I'd disconnected the USB cable;
At this point the battery was at about 19%;
I clicked factory reset with wipe SD card;
After a few minutes I check the phone and it's completely blank. I figure it's doing something and can't turn the screen on so I leave it for a few more minutes;
Eventually I grow concerned and assume the phone has crashed, so I hold down the power button to do a hard reset.
After this the phone does not turn on.
It does the following:
If I try to turn it on it displays the SGS2 logo (with the yellow triangle) for a few seconds and then turns off.
If I connect it to the power it displays the loading screen of the battery charge app for a few seconds and then turns off.
Sometimes if I mash the buttons it will flash on and off with a pure white screen until I hold the power button and turn it off.
Any ideas, guys?
My only idea is that something crazy has happened with the battery as I did swap my extended battery with my girlfriend's normal battery last night. As I work in a phone shop, I'll charge up the battery in another phone to make sure it has power.
But I know the battery has power, and the phone it doing exactly the same thing with my old 1650mah battery (which may or may not have power in it).
Any ideas? I was going to be selling it for around £200, so it was gonna really take the load of my shiny, new S3! 0_o

If it was bricked it wouldnt turn on even a bit. Just charge it or try changing the battery.

If I try to charge it it displays the SGS2 charging screen for a few seconds and then switcher straight off.
I just got into work and tried my colleagues 2000mah battery which had 32% in it. Exactly the same problem. WTF????
Thanks
Edit: FYI, it turns off before entering download mode or recovery. WTF????
Maybe you hit this ?

That's just what I was thinking, actually
I couldn't find a description of what actually happens when this brick happens. The page doesn't really say... Does anywhere say?
Edit: I swear I didn't even flash the Siyah RC6 that was known to brick the phones either... -_-;;
Thanks!
It's not just a specific kernel, more are actually faulty. The whole story is here.

your phone is ok as far as it shows u the s2 logo
you have 2 things to do , try to go to recovery or download mode and formate data/factory reset then flash another rom , btw what kernel u used before your phone go to this situation ? if you were using stable kernel "cm,neak,fluxi,syah stable" so you are safe from hardbrick bug , and the hard brick bug is done only if you have faulty kernel and wibed your data through recovery , and this isn't your situation , so don't be afraid

Thanks for saying, but I can't get into recovery or download. The phone switches off before then!
That's what's so confusing! xD
Thanks
With a known good batter try hard resetting to download mode 2x in a row.. Hold the button config to get into download mode.. Hold it through two restarts.. Might work.

I've nuked mine a few times with buggy kernels, sounds like a similar situation. I got my device back by flashing CM9 resurrection, then flashing Siyah, and finally from CWM flashing an ICS-based stock ROM.
I'd suggest taking a backup of your efs unless you're selling it with stock.

i am having exactly the same problem.i did a factory reset after flashing siyah kernel (SiyahKernel v3.3.1) on Resurrection remix v2.2.let me know if you guys find any solutions
JIG
try to use a download mode JIG.
I'm not sure if a link will violate xda-rules....
google it
dont worry
if you boot up and are getting the sg2 logo then you have not bricked you phone.
to fix simply download a .tar version of any rom and run odin to pda reinstall if you wanted to you could go the whole hog and reflash a fresh cf-kernal (rooted or stock) and then flash fresh firmware. just remember to get the kernal that originally matches the (ithink) your correct baseband ie xxki4
there should be no worries aslong as you dont pull the plug.
could have had a worse error saying installation incomplete please use kies then you would have to had taken battry out reinserted and hoped the three butn combo for rec. mode worked happened to me awhile back lol
hope i helped you
ps never read your post fully just skimmd the jist of it although the above should be applicable
also try resetting your battry stats in cwm
finally fixed
thanks for the help everyone.i have fixed it now.it seems like the problem was with the updated version of siyah kernel .i managed to put the phone in download mode.(kept the phone on the charger for a while. than, i don't know some how when i tried to go to download mode it did).and flashed siyah kanel v3.2.6.4 via odin

Phone died on its own today... Any advice ?

Hi guys,
I'm truly desperate tonight. This morning I was at work and recieved a phone call. Answered, everything was fine, and put the phone back again on my desk. Half an hour ater, wanted to send a text, so I tried using the phone: screen remained black. I was like "ok,, this stupid S2 froze again, I'll just reboot it bu pulling the battery out".
Did so and........ still nothing. WTF? So I tried plugging it to charge (AC adapter). No "battery" symbol on screen, nothing. Starting to freak out a bit... I trie with a colleague's AC Adapter, same deal. I also tried with his battery, still no go. Phone remains totally off, nothing on screen, can't enter download mode. The only change when I remove the battery/put it back in is that the phone remains cold at first, and then a couple seconds (30?) after I hit the power button, you can start feeling CPU/GPU getting warmer on the right of the camera lens. So basically there's electricity flowing.
Tonight I gave it a go and opened it up to check if something's fried inside. The only odd thing was that BAT500 (google for some explainations) had leaked but the leak was NOT (and I really mean it) causing damages (yet). I removed the battery, as it does not impact dramatically the phone (just causes the date etc to reset to 01/01 when you remove the battery, apparently). But phone still won't boot, no logo, no "battery chrging", no light on screen...
This really looks like the "hard brick" emmc bug, however I've been running 4.0.3 rooted with Chainfire's CWM kernel for the last 6 months or so, and I never did any wipe or "reset to factory". So the so-called "hard brick bug" shouldn't occur. But symptoms sure look like it.
So to get back to my opening phrase, I am truly desperate. I do have backups of nearly every SMS/MMS (maybe not the last 2-3 days but well... I'll get over it) on my Gmail account, however what I don't have is a backup of my contacts. For some reasons, I don't like my contacts to be synced with Gmail, so they were left on the phone's memory (and not the SD card, because I always thought (how stupid of me) "well why put a SD card inside when there's like 16GB of embed storage ?!"). So I'm f**ked for my contacts, and also for many many pictures that were still inside the phone and not yet extracted to my computer.
So the question (for which I fear I already have the answer): is there ANYTHING I can do? i've contacted a guy in Paris who owns a USB jig, so I'll give it a try this week-end if he's available. But other than that, is there ANY way to recover something from my brick? Or someone witha genius idea of how to turn it back on for at least 5-10 minutes... ?
Any help is appreciated I'm really feeling stupid, as I'm always backuping everything, and I probably have backups of backups of backups.... but just not for this stupid phone...
Regards...
PS: Symptoms:
* Black screen, nothing booting nor charging
* When putting battery back on, nothing happens. If I hit the power button, phone starts getting just a bit warm near the lens (right side of it)
* No download mode
* Power+Vol down+Home + usb connection: nothing on screen, nothing on computer, no USB detected, ODIN sees nothing
* No it's not just the screen who died
Edit: Could JTAG be the magic solution? If so, is there any thread here like the "find a USB jig near you"... ? Wouldn't find the equivalent.

[Q] Phone keeps resetting after startup (Internal memory/battery issue)

Hello everyone.
After several hours of googling and going through tons of pages here on xda I decided to make this post.
First, let me explain when the problem started:
The issue
Yestarday I was playing candy crush when suddenly the game started to get "laggy". I didn't think of it, exit the game and left my phone on the table. A few hours later I wanted to use it again only to find the small hard drive icon on the top saying something about Memory almost full. I clicked it and it took me to "All installed programs". I saw that it had used 1.9 gb of the total 2gb and only 20-40 mb were free. I started immediately to uninstall apps that I no longer use to see if this could help. It did for a few seconds but the memory got filled fast again.
This is when I started to search the net for solutions. The first post I read was to delete some log files so i did that. But it didn't change a thing. I thought to myself that I should make a backup of my stuff so it wouldn't go lost if I had to wipe the phone. But before I got to it my phone shut down. Now, when I turned it back on it would just start Media Scan and shortly after shut down. This is where I am now.
I am running stock ROM (have never rooted before).
What I have tried
I found the stock ROM (4.1.2 I think) and I flashed it with Odin thinking this would stop my phone from restarting. It did not.
I have tried to clear cache from Recovery Mode several times with no effect.
I have tried to wipe the phone from Recovery Mode but when I am half way through the setup process of setting up the phone for first use, it shuts down.
My battery also drops in power after the shutdown happens, so in this very moment I am waiting for the battery to charge fully so I can try to calibrate.
Please let me know if you need some additional information and I will happily provide what I can.
Thanks in advance!
You have flash stock and it still shuts down? Hardware problem. Battery old? Try with charger plugged in. Flashing stock makes it like new so there should be no faults. Id say battery is about had it. What firmware did you flash and were from?
My phone (and battery) is almost 1 year old so im still under warrenty if something fails. I just don't want to hand it in and wait weeks to get it back if I can handle it myself
Yes I flashed with stock ROM from samsung-updates.com/device/?id=GT-I9100 so it should be good.
It makes no difference if the charger is plugged or not (which I find odd cause shouldn't it be able to keep awake while on alternating current?).
At the time typing this my phone is online and I am currently backing up photos (yay!!!). What I did was to not type in PIN code so maybe the sim card is the trouble (also 1 year old). I will report back when everything is backed up.
Update:
4 seconds after entering the PIN code the phone shuts down. Also it plays about 10 silent "clicks". Can't hear if its from the phone or from the speaker.
Update2:
Alright so I tried inserting another sim card that I have which has no pin code. The phone boots (but only when plugged) but shuts down after statup, exactly the same place/ after the same time as when I use the other SIM and enter the code.
I have had it online for 5 minutes now without typing the pin so my guess is that it's some setting it loads with the sim that makes it crash (but its a wild guess).
It's also worth noting that it doesen't drop in battery capacity when it shuts down ATM.
Id still say battery problem but could be wrong.
I see some sort of flicker on the screen just before it shuts down. I don't know if this could help someone to address the problem.
For the full memory issue i solved wiping log files in the "/data/log" dir, i had almost 1000 log files, 1 MB each.
Hope this is your problem too.
There is hardly anything left in the /data folder. I have tried to delete the logs (65 mb) from Phone/log but that didn't change a thing. Im going to send the phone to the company i bought it from next week.
Ive recieved a battery that I ordered from china and the phone works now. So the problem was the battery just to let everyone know.
Glad you sorted it.

Restoring Interrupted, Possible Bricking?

I started to restore to a back-up I made two days ago in TWRP and I think it got interrupted by my accidentally canceling it. I was on my way out the door and wasn't paying attention and must've touched the screen (phone in hand).
Now it behaves much like cadcamaro's description in his recent post about having tried to install a Z2 ROM. I can get into FastBoot, but all options simply shut down the phone. If I don't choose an option, it shuts down by itself after a a minute or so.
Power + Volume Down gets a short vibration.
When I plug it into the PC, Power + Volume Up Gets me a blue LED that stays lit, but the PC (and Flashtool) doesn't see it.
Power + Volume Down gets an orange, then green LED with vibration that repeats.
The first time I realized it was screwed up, I did get into Recovery. I tried to re-run the back-up (which is saved to external SD), and it shut down.
Thanks, all.

Have you tried pressing and holding the reset button next to the SIM tray? Try holding it down for 2+ minutes and see what happens.

Thanks for responding, BladeRunner.
I just tried that in a variety of ways, and got either no response or it simply did what it was doing. I'll explain;
Believing the phone to be OFF, nothing happens for 2 1/2 minutes of pressing the Reset button.
Same goes for a variety of combinations of switches also depressed, such as Volume Up/Down, Power, or any combo therof.
(At this point, I'm uncertain if I even have much of a charge in the phone.)
FastBoot is the menu that has the green Droid with a choice of 4 options, including Power Down, Continue to Power Up, Factory Reset, and something else, correct?
The one time that I did get that to appear during these last few attempts to use the Reset switch, the menu simply shut down after 15 seconds. I continued to press the reset switch, but nothing happened.
Plugged into the PC, the phone continued to cycle Power-On every 8 seconds, with the Orange LED followed by the Green, then Shut-Down. (Apparently, as without the screen on I have no idea what it's really doing....)
Plugged into PC, Power Button in and Volume Up gives me the Blue LED that stays on constantly, but depressing the Reset Switch does nothing.
As I stated earlier, I have no idea how much charge the phone has, so I'm leaving it on the PC in the Blue LED state. It may not be charging, but all it does when I try to charge it any other way is cycle through every 8 seconds with the Orange & Green LED.
Sigh... This would be the first phone I've ever bricked, and I've been messing around since Vivo on the V3m, and always very careful. Sucks since this has been my favorite of them all.

I'm not sure what fastboot mode on the z3v looks like honestly, but your description sounds about right. You could try getting into xz dual recovery again and wiping the cache maybe? The instructions to there are in the xzdr thread. If you can get there wiping, a factory reset or flashing something might work but failing that you might want to try letting the battery drain all the way down. If you just let your phone sit that can take a while ( days at least) or you use a rubber band to hold down the poet and volume down button, I believe, to drain the battery. Once its dead completely connect it to your PC and see what happens.
A failed flash on a eeprom can be a hard thing to recover from, sometimes it can ruin the eeprom preminently, depends on the state the eeprom was in in the flash process,usually in erase process it will not be recoverable. . Removing power will not reset the eeprom, eeproms are preminent memory, but it can allow the device to be discovered again hopefully.
You have to get something to erase and flash again, if the eeprom is in a failed state that may be impossible to do.

So I'm assuming the eeprom is like an order of operations & file allocation index or something really basic upon which everything else is built? This is an old school term for file index, right?
So even if I manage to get everything wiped, I need to start fresh by installing the stock ROM that the phone came with and progress to where I can load the saved Back-Up that's on the External SD?
If the eeprom gets wiped as it's re-written from the Back-Up, and interruption blew this process mid-wipe, will my Back-Up still be useable?
How is it that battery drain will help my device become recognized by the PC?
Thanks for all the help.

Correct. Your backup is safe as long as you don't mess with sdcard storage. You have to get the eeprom healthy before you can do a recovery.
Back to working on my bricked Z3v...
Plugged into PC with Volume-Up held in yields solid Blue LED. This is the only time that in Windows 8.1 Device Manager that the phone shows up as a connected device. The name of the device is "S1 Boot Fastboot", for which there is no driver installed. When I navigate to Z3-lockeddualrecovery2.8.23-RELEASE.combined / files / adbdrivers and try to install the driver, Windows says "Windows could not find driver software for your device."
However, in the "Events" tab it shows three previous dates that the device was configured. It listed the device as such "Device USB\VID_0FCE&PID_0DDE\BH900JCL1N was configured." on those dates.
Was there something different I had to do for Windows 8? I cannot remember, but this feels familiar.
Driver Name: Google, Inc. (WinUSB)...
Status: Install failed
Meanwhile other drivers do install. What gives?
Well I was hoping for a bit more. Extremely frustrated right now as it took me about 15 minutes just to get here to see that nobody can help.
In the meantime with all the **** I've downloaded trying to fix my phone, I've completely scxrewed my computer. 4 virus scans later and I'm still f'd.
Great.

Your phone is toast and the only way to get it back is through the Flashtool imo. It wouldn't be common for many to have your circumstances with a bricked phone so you aren't getting much feedback. See if you can follow these instructions with Flashtool that I posted. I've gone from 4.4.4 to 5.02 non-rooted and back to root on 4.4.4 and then forward again so it has worked well for me.

See if you can download the 4.4.4 firmware after getting flasthool 09.18.6 installed. Granted my instructions are from Windows 10 64 bit but it should work.
Couldn't do any of it. My PC is s screwed up, but even in Safe Mode I was unable to load drivers that would recognize my z3v.
So I'm typing this on my replacement phone that came today via FedEx. I was very nervous about getting a refurb, but this one really is like new. I managed to get the glass protector of the old one, rinse it off, and apply it to the new one.
Now I'm on unrooted kitkat.
If I root and install TWRP, can I simply flash my saved lollipop backup from my SD card and make this phone exactly like the other one was before I borked it?

I wouldn't recommend that. I have used titanium backups before from one device to another and it worked. The whole system from a twrp backup really doesn't sound like a good idea.
OK. Think I'll just be patient and do it from scratch. Have to get the computer cleaned up first.
Really glad to have a clean, new z3v back again, but this ordeal has certainly impacted my confidence doing this stuff.
Thanks for your help, everyone.

Old Z2 Tablet SGP512 Given All It's Got?

As the title suggests I have an old Z2 tablet that has been an absolute work horse for many years. I was using it one night and the Android OS prompted me that the device hadn't been rebooted in 28 days. So after I was done using it for the night I rebooted it. Only, it didn't reboot it just stayed off. I tinkered with it for a while and got it to show the Sony logo but then it just went dark again. The device is rooted and I have TWRP on it. So when I got it to turn on again I booted it into the TWRP recovery. I proceeded to clear the cache and also attempted to make a current backup. However, the backup would fail after running for several minutes. I decided to try backing up to an external OTG USB drive but the device needed to be rebooted to detect that the OTG USB drive was attached. So from TWRP I selected "reboot recovery".
Unfortunately that was the last time it worked. The screen will not come at all. When I hold volume+ and power it vibrates 3 times but still doesn't boot. I plugged it into the charger even though the battery charge last showed at 85%, but with the cable connected the charge light doesn't even come on. I tried plugging it into my computer but it doesn't detect the device has been connects and adb devices doesn't show anything in the list.
I read on a forum to try drying it out with a hair dryer and while the device hasn't ever gotten wet it has been humid here so I figured what the heck. Unfortunately that also hasn't resolved the issue.
Pretty much everything I've tried hasn't worked. Even the red reset button under the top panel just causes it to vibrate 3 times.
The device has been in this state for a week now. I was hoping maybe the battery would die and then I could recharge it, but since it still vibrates 3 times I'm guessing the battery still has a charge.
One thought I had is that maybe the internal storage is either dead or corrupted.
At this point I'm wondering if the device is a lost cause and I should just let it rest in peace or if there's any other solution. Even if there was a way to factory reset it from it's current state that would be better than having it be a paper weight.
Any suggestions beyond what I've already tried would be greatly appreciated. And, yes, I may look into seeing if I can get it serviced however there's definitely no warranty and I don't really want to poor money into it since it's probably time for an upgrade anyway.
Why is my phone vibrating 3 times and won't turn on? - Sony Xperia Z5
When I try to turn my phone on it just vibrates 3 times and does nothing after that, just wondering what the problem could be?? - Sony Xperia Z5

The device vibrated 3 times, that's good, then it is off.
"Sony writes: This is how you force the device to turn off:
Press and hold the power button and the volume (+) button simultaneously until the device vibrates three times."
Did you try to put the device into flash mode after that? I think only a complete flash will bring the device back to life.
