[Q] Help Needed for a complete NOOB - Galaxy S II Q&A, Help & Troubleshooting

Hi all, new member as i just got a samsung galaxy S2!
Ok, so i have bought a sgs2 of a friend at work. He was messing with it(trying to root it, he thinks) and did something wrong and messed it up, so i bought it of him for very cheap to have a go at fixing it. Things that are wrong with it - when you turn the phone on it just comes up with samsung Galaxy S2 gt-19100 with a yellow triangle under it, it wont go any further. I can get into the download menu, but i cant get into the menu to do a factory reset. Another thing is it will not charge, when i plug it in to the mains or a pc it just comes up with a battery and a little circle inside it, but dosnt move and dosnt charge! O and yet another thing i dont now what firmware was on it before, but i no it was O2 if thats any help. If i have left anything out that you need to no, ill be hear all night trying to get this thing going! Is it even possible for this to be fixed as i had a good look threw this website and the internet and cant find anything about this.
Thanks

1). Check under battery for exact model number
2). Download a stock ROM for the model you find
3). [optional but recommended] check the battery level and if necessary charge in another phone to make sure it's not going to die while doing the next step
4). Flash a stock ROM via Odin
5). If it doesn't boot, go to recovery and factory reset

Hi, thanks for ur reply Oinky. Where would i find a stock rom? I am completely new to this sorry, and under Model, it just says GT-19100, is the bit below anything to do with it aswell, SSN: -19100GSMH? Also at the min i cant get into recovery to do a factory reset? Again sorry for my ignorance and thanks for the reply

You can find stock ROMs http://www.samfirmware.com/ or http://forum.xda-developers.com/showthread.php?t=1075278, the latter having a tutorial too.
Are you sure you can't get into recovery? Your first post made me think you were getting into download mode and thinking that was recovery. Vol Up + Home + Power (from off)

Hi, sorry for confusing, when i hold vol up home and power it dosnt do anything, just turns the phone on, well to the screen it wont go past! Also how do i no which stock rom to choose? what letters should i be looking for?

I think you're still doing it wrong then, as I don't think there even exists a kernel for this phone which doesn't have recovery. Hold volume up and home, then also hold power for about five seconds.
Regarding stock ROM, just pick the latest for your region (presumably XEU if by o2 you mean UK o2).

Flashing literally any I9100 kernel, be that stock or custom would still have recovery. I suspect the device is much worse off than first realised.

Once you flash the stock firmware the phone will boot up normally again.
Any firmware will work.

any ideas how i would fix a handset that is alot worse than 1st expected??

Follow the Odin method and you will be fine. As long as you have Kies closed (This includes the 3 kies apps that run in task manager!) there will be no problems.
Hopefully you will get a bargin on a new smartphone.

Well that didnt go well, it fails with odin3 after about 5 seconds, Should i just give up?

What error messages if any do you get? Screenshots or logs would help.

[Q] how to unbrick Galaxy Europa GT-i5500?

Hello
I have the next issue
I have a Samsung Galaxy Europa GT-I5500
And it bricked when I closed odin 4.36 after, when the phone was in downloading mode due that there was no completion. I wanted to install a newer version of the clockwork (mod) recovery.
I installed an old version but was unable to install the CyanogenMod (hte one from psyke83) that I wanted. And after I wanted to try a newer version of the clockwork (mod).
And now the phone is with the PC---to Phone icon brick mode.
I tried the volume down + main button + power off and isn't working
Also i tried to run the one click unbrick and isn't able to connect to the phone. Seems that the phone doesn't reach the computer
I tried an usb list (lsusb) in the ubuntu and does appear if i connect it.
I tried both in windows 7 and ubuntu
Do you think is a softbrick? Any clues? recomendations or questions for more details
did you find any solution..
i have no warranty since it as directly imported..i have the same problem ..
i was trying to backup my rom when it bricked.. (using rom manager) .... i tried volume down + home + power button (disconnect button) but nothings showed up.

I had a problem with the buttons on the phone the volume down wasn't working.
What do you mean by home button the one with the home icon or the main one with the metal borders because is that button the one that you need to use.
I also tried the resitor of 301kohms between the pins 4 and 5 didn't work.
Now i have the 2.3.7 working stable at the moment
try that combination of buttons if not tell me
I am pretty sure there is nothing you can do about it, if it is completely bricked.
And the phone won't turn on, in any case what so ever?

Depends if it is hard bricked or soft bricked. If the screens turns on and appears the PC---/!\ --- phone. The he can try to use the three key combination or the usb homemade jig. Otherwise he can try to find someone with the JTAG
search in google JTAG galaxy for more info.
sounds like a hard brick. People claim that taking the battery and sim out of the phone for 30 mins (min) and then putting back in and booting to download mode sometimes works
You could try that
MY BROTHER IS IN THE WAY YOU DOWNLOAD but equally can not install any OTHER ONE IS A STRONG BRICK
On galaxy s this also happens from time to time, even i had it once. Try if Odin possibly connects anyway and flash again, if not, remove your battery leave it out for 60 seconds and then try if you can get to download mode again. You definitely have not hardbricked your device...

Did you already try: vol up, menu, power on (by this order, holding them all together in the end) ???
(It might be that for your device you should press and hold: vol down, home button, power)
Did you try taking out the battery (for 10 - 15 secs) and trying the above combination again???
Also you might find this page of interest for your case: https://forum.xda-developers.com/showthread.php?t=1734997. Credits to @neerajganga
Please take a look at your PM messages.
A last comment; in my experience, using the latest version of Odin and firmware from the links I sent you, never required extra files (like pit or any other type).
Best of luck! :good: Share how it goes!

Phone died, Want to Sell. Personal files?

Hello,
I have a Samsung Galaxy S II AT&T. It is unlocked, rooted and custom rom flashed. I used it for a few months then it starting just shutting off. It rebooted the first time or two it happened but then it refused the boot the 3rd time it turned off. I have tried numerous new batteries, soft/hard reboots. I tried holding in the up/down volume with power button to try to get into recovery but now nothing works.
I would like to sell the phone on Ebay for parts but I had personal information file and photos on the phone.
Any suggestions on how to remove personal files on this phone? I am concerned that if I sell it and a technician buys it and gets it running that they will find my credit info. etc. .
Or do I just break it further and through it away? I am undecided on what to do with this phone.
I purchased another phone for a girlfriend and now she claims that phone will not boot up either so I may have two phones with the same problem.
Please advise.
Take out battery hold both volume plug usb into phone and computer and see if download mode works

Tried a jig? If it doesn't even go to download mode that's not a good sign
When I hold down the both volume up/down and the power button it goes to a screen called.
Warning!!
A custom OS can cause critical problems in phone and installed applications.
If you want to download a custom OS, press the volume up key.
Otherwise, press the volume down key to cancel.
Nether option starts the phone.
Before I had a problem with the phone it would go to clockwork recovery.
I would like to go to clock work recovery and try flashing a new rom.
but I can't get there.
Any ideas to get this phone fixed?

That is download mode. That is exactly what you want. Go to the stickies and read the back to stock thread and follow the directions. Then you can boot the phone and finally get your data off and erased or you can keep the phone.
It went to download mode. What do I do from there?

u can still get into download mode, thats a good sign. that means its not bricked YET.
remember, as somebody said before "a brick is a brick" . no sign of life what so ever. try this webpage and follow the directions for getting "back to stock". http://forum.xda-developers.com/showthread.php?t=1511838
from my understanding, u have just landed on xda. i would suggest u get somebody's help who knows stuff better than u before u brick ur phone. remember every random thing u flash would take you closer to brick. i had been through this hell.....and somehow managed to get out...lol
good luck
by the way, i tried a lot of things to get it going including flashing a stock rom. nothing worked when i flashed a kernel "for i777 "(ics/jb depending on the rom before u went into trouble) and it was back to life.....as simple as that

Problem re rooting (cant get into download mode)

So I have been trying to figure this out and I am sure I could if I had more time. I have an ATT SGS2. I first got it with GB and then rooted it and flashed CM9, then to CM10. After wanting to change things up I went and tried to flash miui but it didnt seem to work and slightly bricked my phone. I then went back to stock firmware but it was for the International version (UK) and came with 4.0.4. Now from there I wanted to re root the phone and attempt the miui rom again but I cant get into download mode. I know that you would have to also hold down the home button but I only have touch buttons so I am thinking thats what the issue is. Can anyone help me out here I wouldnt have posted this but I am in the middle of packing to move across the country so any and all help would be very very appreciated.

Not sure what you mean =(
Did you actually flash a different bootloader? If not, it should still work. To get to download mode, use "adb reboot download"
Also, to root, you could probably just use ExynosAbuse.

I am confused because it wont go into download mode. my back and search button dont work either if that helps.
Recovery-hold volume up,volume down, power button until you boot into recovery. Download mode- same key combo, but with it plugged into the computer. Your back and search buttons don't work because you flashed the i9100 firmware.
The I-9100 package you flashed evidently contained the secondary bootloader, which changes the button configuration for download mode. If Phalanx's button combo for download mode doesn't work, try pulling the battery and leave it out, then hold the vol- button and plug in the usb cable that is connected to your computer. The computer will supply the power, and that should put you into download mode.
Once in download mode, go to the download repository - link in my sig - and flash one of the stock packages that contains bootloaders, or just flash the UCKH7 bootloader by itself.

The You need to change the kernel to one compatible with the I-777. It would be best to change the system as well. I would suggest that you find the I-777 firmware you would like to try from the development forums in this section, and flash that.
Yeh creepys right. It you absolutely want to stay on that firmware flash ajk kernel it will fix your back and search buttons. As always, read instructions on flashing before doing so in that thread in development section. Good luck,happy flashing.

Root or no root?

It's still very early an I see a few people going stir crazy over finding a way to root their phones. I for one am not sure I want to root just yet, the reason being Samsung pay. If it's going to be as awesome as they say it will be I don't wanna miss out due to tripping Knox.
Now I do love flashing and all things root related but I'm willing to hold out.
What about you? Root or no root? Why?
I root right away even if I don't have a "good" reason too. Its the because I can. I don't really care about the tripping knox thing I guess because if you have insurance there is always a chance the device could get "broken". Then you don't have to worry about if its tripped or not. Thats the position Samsung has put me in I wouldn't typically do something like that. So ya now I'm just waiting for TWRP then I will try and make a ROM.
I tried to use chainroot, and got stuck on the logo screen. normally you'd battery pull, go to recovery and wipe data. but i can't find any way to shut down the phone, before doing power-upVol-home.
And now i've tried to odin a stock recovery to undo chainroot, odin fails. could re-run odin with auto-reboot off, but again, no way to shut off and go to recovery.
at this point i'm stuck with the blue screen asking me to use smart switch on PC to do emergency recovery. but smartswitch says the device is not recognized.
thoughts? thanks!
I don't care about warranty just samsung pay. I heard it was harder to make roms with exinos is that true?

Not sure what device you have but there was a video that said not to use the edge version of the root, and to use the regular S6 version. Running the S6 version will fix your broken device. Take this with a grain of salt, I'm just telling you what I saw. I will post the video link if I get a chance.
PS not sure if this actually helps you or not..
Rooting broke Google Play Movies on my phone, battery life was miserable and phone never went to sleep. After I unrooted everything went back to normal. So I am not going to root and just wait until things are cleaned up.
Every phone I've ever had has been rooted as soon as I got it. Not this time though, because of Samsung Pay.
If rooting breaks Samsung Pay, I'll never root the phone

not for me right now: i have the turquoise error screen telling me to use smart switch. volDown + power for 7 seconds turns the screen off... and then right back on a couple seconds later. and i can't seem to slip in the recovery key sequence during that gap.
volDown + power + home is a diff story: that brings me into download mode. but i don't have anything that works in odin right now without failing. very possible that i don't have the correct rom, or that the rom is fine but i just need to go into recovery mode to complete, but i can't seem to do that!

How about volume up+power+home to stock recovery to perform a factory reset?
No root for me I'm afraid! If I root this device I lose my nfc payment app (Semble) as it checks for root and locks the app if it's detected. Besides I've rooted every other phone I've had since iPhone Gen 1 and I don't really have the time anymore now I've got a 1 year old boy!

Why is ODIN failing? Drivers installed? Where did you get this recovery? If ODIN can see your device you flash back to unrooted stock firmware.
Also, someone mentioned that you can Vol down + power will shut the device down. As soon as the screen goes black take your finger off the power button, press and hold Vol up + home then press power. You can go right from download mode to recovery with just the buttons.
great questions:

I would love to hear if this is a good source. also, I don't know if it matters exactly which of those firmwares to choose (there are many, you choose country and carrier)-- i don't know which one came with this phone as it was sent as a demo to me and i didn't take a screen shot of the info screen (does it matter?)
Also, someone mentioned that you can Vol down + power will shut the device down. As soon as the screen goes black take your finger off the power button, press and hold Vol up + home then press power. You can go right from download mode to recovery with just the buttons.

2. that doesn't work for me, tried 15 times. I'm stuck with this turquoise error screen telling me to use emergency recovery in smart switch. i can easily get over to dload mode too. From either place, volDown + power gets the black screen and then immediately goes right back to the turquoise error screen, ignores anything else i seem to press, can't get into recovery.
No root for me either. It's hard lol. I miss it mostly for the adblocker. But I'm too worried that rooting with make it so I wouldn't be able to use Samsung pay when it comes out! If a root method is released that won't trip the KNOX sensor then heck ya, I'll root right away!

Did you ever fix this? I'm having the same issue, but because I flashed TWRP...
I need to use Smart Switch, but that says my device is unsupported... SM-G925F
EDIT: Re-flashed root, and all good again!

yep, i think that was a key step for me too: re-flashed the root thing, after trying to re-flash stock a bunch of times.

SAMSUNG S6 stuck on startup, cant turn off.

Got a samsung s6 phone stuck on the startup logo, cant turn it off.
The only way i can interact with it is; volume down + power off that makes it just restart to the stuck logo.
Volume down + power button + home button - takes me to where i can download a custom firmware.
Thats pretty much it, cant do the volume up + power button for firmware reset or simply turn it off....
Haalp, tried to custome update it with a firmware to the phones version, still stuck on the startup logo..

I assume it's unremovable battery...damn i hate those phones with unremovable batteries, so have you tried volume up + power button + home button?
This should make you boot into recovery and be able to factory reset your phone.

Cant remove battery, but got the original sticker on the back with the S/N and model number. SM-G920F. As i said in OP, thats not possible, cant get that option up. Cant even power off the device.

Ok, here's another 2 options you can do.
1-hold the power button only and see if that shuts it down.
2-leave it like that till the battery discharged completely, then charge it for a few minutes then try booting into recovery using the volume up with power and home buttons.

Powerbutton wont shut it down, its drained now... But once i put the charger inn, i end up at the logo again. Cant get the flickering light on the back button to light for recoverymode.

Did you try to boot into recovery without putting it in charger?
Or plug it in the charger while holding volume up + home buttons?

Tried the volume up + home + power... No respons at all.
The only thing i can get to work is volume down + home + power - takes me to a custome download software menu with the option to custom download or simply cancel/restart device.
Or volume down + power, for a simple restart that takes me back to the frozen samsung logo screen.
I tried to download a custom software compatible with the phones model in odin software and kias... Same result, back to frozen samsung screen.

Your only solution is to reset data, but i don't know how, even if you tried adb but you don't have USB debugging enabled, so adb won't work, you're in some deep problem, try giving it to some service center he might have a software tool that can simply wipe data without troubles.
Some users say that holding the power button for 15 seconds should shut it down which didn't work for you either, so your only solution is to give it to a service center, it should cost you nothing, it's just a reset data....i guess.
This is a old phone, and its userdamage not softwarefail. Dont think the support will take that in for "fix".
Also not my phone, so i could not deliver it for service. Got it cause the owner wanted to trash it, but i could have it if i got it to work.
Found a software for my country, some version below 5.1.1 and 1 software over. But now i get fail in odin. Why do that happen?
The new error message i get when i download firmware thats for my country: [CM] SW REV. CHECK FAIL. DEVICE:5, BINARY:4

You're trying to downgrade to an older bootloader which isn't recommended and will cause problems.
What do you mean by it's user damage, did you trip knox?
Or did you try to flash a custom recovery? Or you tried to root?
If no, and you got bootloop while the phone was upgrading, then it's not your fault, and it's a software damage.
If yes, then you should fix it anyway because if you didn't then it will be useless and the s6 isn't old like you said, it's still new, if you have an s2 like mine then you can call that old :silly:

By userdamaged, i mean... Ehm, the owner probably downloaded some custome software or tried some kind of "jailbreak" i guess. I rlly dont know.
Just as i read online, this seems to be a hard brick of some kind... If i cant fix this on my own, its prolly going in the trash. Since i got it for free cause the owner wanted to trash it as he could not fix it.

Hard brick means it's a hardware issue, so if you believe it's a hardware issue then there is nothing you can do, what i meant was you should "Ask" how much would repairing it will cost, if it's just a software problem then it should cost a little, and you will be the winner at the end because you got the phone for free and you made it work....and it's an s6 phone...Something i dream of LOL, and if it's a hardware issue and will cost you a fortune then throw it in the trash or sell it as a spare parts phone or something.
Sad news then Ill try to find out if its worth it.
I have pretty much tried everything i can at home. Anyways, thanks alot for the help
