[Q] I need some serious help/guidance! - Galaxy S II Q&A, Help & Troubleshooting

It all started when i tried to root my Samsung Galaxy S2.
I tought it was to confusing to use the long way of rooting so i used to supercurio auto root kernel. I followed the instructions and everything went fine, but when the phone rebooted (like it said it would) it got frozen at the Yellow Triangle boot screen. After this i tried to flash many different kernels without luck, i tried to flash firmware roms aswell but that didn't work either.
The battery seems to be depleted and there is no way for me to open the Download Mode.
Im really new to the android world and i would be the happiest man in the world if i could possibly get the right answers.
P.s! When my phone actually had battery i couldn't open the Recovery Mode

No download mode then you need the USB recovery jig ebay/Google .
With a charged battery .
jje

But i can't charge it since the phone is stuck at the empty battery icon with the looping circle in it (which is stuck aswell). The phone just gets hotter when i try to charge it but i doesn't do any good at all

I think you'll just have to buy a jig and find a way to charge the battery again.
Maybe you can try a full battery from a friend?
Or charges yours in the Galaxy S II of a friend.
After that just try to reflash en wipe everything in cwm.
Good luck!

OKey, thanks for the reply but what does the USB jig really do? I have heard that it only boots the phone into download mode. But even if that works it still wont get the phone to operate as it should since i tried to flash different kernels before when i had battery left.
If i charge the phone right now, it will first show me the empty battery and then it just reboots back to the battery icon. If i press Volume down - Home - Power button it just says that i have to low battery and that it wont go into download mode. Recovery mode has not worked since the first time i tried to flash to Supercurio's auto kernel.
Plz help!

The experts should explain it better but the jig I think allows you to write data directly to the nand. There should be external chargers for the s2, you could try searching for that too.
I suppose what you should take away from this is that it pays to avoid shortcuts. I'm pretty sure it says on the cf thread that the auto root doesn't work on the phone.

Maybe you should try once more flashing a complete stock rom with repartion and pit.
A jig just puts your device into download mode.
It is very cheap on Ebay.
I don't think it is smart to try charging.
I once had a problem like this with the original Galaxy S .
I went to shop where I bought the phone and asked for a battery.
Just try to get a full battery and jig.
I think that is your only chance...
Good luck!

Have you tried letting it charge for some while? The S2 gets a little hot when charging so thats probably not a problem, if i were you i would let it charge for an hour or so and then try to enter download mode again

Thanks but if i plug the phone in with the charger nothing really happens. On the screen it's just a empty battery and within that battery there is some kind of circle that should be swirling but it is frozen, therefor i dont think the phone is actually getting any power...
Even if i set it up with a USB jig and a new battery, what kind of kernel should i use? And should i flash it with a new firmware?
I really have no clue on this one.
The phone only reacts to the button combination regarding download mode, but whilst in there it just says "low battery !! Can't download !!" and that's it.
Any more advices? I will die of happiness if someone helps me with this!
Thanks.

Looks like you need a service centre
or flash stock rom via Odin after accessing download mode via buttons or recovery jig .
You dont want a kernel you want full new stock firmware .
jje

Yea i got that now, but i live in sweden and before all of this i tried the swedish firmware version and it just says FAIL! in Odin.. im sure it would work out if i could get the firmware to reset the phone, which it does right? I guess i should fix me a battery since it seems i can't charge it properly. Any one who could explain it more detailed? It would help me alot.

[Q] [HELP]Completely bricked vibrant. wont even turn on. plz help

ok so i know how to do things on my vibrant but dont really know exactly how the phone does things (basically im a directions follower) so im going to try to be as precise as possible
my phone has been rooted for a while and ive been experimenting with a bunch of roms. i decided to flash TWs nero v3 w/voodoo and i was pretty sure id stick with that for a while but some of my games started having issues so i decided to flash the newest axura. now something told me that i needed to disable voodoo first and there is usually a voodoo submenu in CW recovery but there wasnt so i figured it was disabled already
so i flashed it and everything was going well untill my screen went blank
now my phone acts like there is no battery in it
ive tried any button combinations with charger in (wall or computer) or out.
no matter what my screen stays blank...plz help
im not exactly in a situation to just buy a new phone.
Unplug the phone from the charger. take your battery out for at least 15 seconds. plug the phone to your computer via usb. while holding both vol+/-, not power, put the battery back in. you should be in download mode.
use odin to flash a stock rom.
this all should work if you have the samsung drivers installed on your comp.
Go to this link it should help http://forum.xda-developers.com/showthread.php?t=848737&highlight=bricked+phone
btw i followed what both above said and neither worked for me =/
thanx for ur suggestions though
Ive seen alot of these post lately and all were on nerov3 .

Well I guess that your best bet would be modifying the usb charger with resistors. as stated in the link that jewbrad suggested. A similar thing happened to my phone when I tried to go back to stock from nero, but instead of a blank screen, I got a small icon of a pc and phone with a triangle in between. The method that I posted did the trick. Maybe you should try it again and check odin to see if it recognizes your device, even if the phone might look like its off.

Have you tried having odin open on you pc and loaded with eugene's froyo that doesnt brick then with your phone turned off(pull the battery then put it back in) now hold the volume keys up and down at the same time then plug your usb cord that is plugged into your pc into your phone this should get you into downlod mode. If this workes flash it and let odin do its thing after its done running it will reboot and go to a recovery screen then it will try to boot up ounce you see the i9000 screen you can pull the battery again and get it back into download mode the same way you did before and then flash the stock vibrant rom tar file and pit. I dont know if this will work but it cant hurt I know how it is not having your phone working so hope this helps
Same thing happend to me.
Please let me know if you get it fixed.
I was on Nero V3 trying to reflash because GPS didn't work well.
i got in to boot loop so i tried to get back to stock and re-do it,
and this happened.
I took it tmobile and claimed the ota broke it..they sent me a new one
NVM!! link posted by jewbrad had No-Boot phone instruction, and it worked!!!
Oh lucky...I tried that n it failed

[Q] Stuck at boot screen at first and now it isn't charging..

I got some problems with my gt i9100.. So i flashed the CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4 on my phone and then everything went wrong.. I tried everything there is but the only thing I can flash is kernels.. When I try to flash a firmware or a rom odin fails (Can't seem to write on NAND). Also I can't access recovery.. I just get the samsung logo with the triangle below. And now after 2 days of constant trying different methods im low on battery and can't access download mode and if I plug in the charger it keeps flashing an empty battery with a circle in it with a 1 min interval.. Can someone please provide me with some advice?
What exactly did you do? Or you really screwed up which is almost impossible or you just have had bad luck.
Did you try pulling the battery out, pressing the on button for a few seconds and then putting your battery back in? Sometimes it helps when you have charging problems.
So try and give us more information about everything that you did.

Tried that with the battery but it didn't help.. Ever since I flashed the kernel it wouldn't charge.. Jje there's nothing on this thread that could help me with the charging problem and besides that I can't access recovery and can't seem to find villain 1.1 anywhere..

Phone will no longer turn on after flashing Rom

I just tried flashing Android Revolution to my phone. I went through the whole set up process. Went to reboot then it went blank. Nothing. I get nothing when I plug it in. The computer doesn't recognize any device attached to it. I've tried removing the battery. If I leave the battery out for an extended period of time, when I place it back in the phone, my camera flash flashes really quick then back to nothing. It's as if the phone is completely dead. When I flashed the rom my battery was at 90%. I've used various roms on different phones and this was the first time I did it to my Galaxy s3 and this is the first time it's ever happened. Talk about frustrating. Any help would be appreciated but I'm not holding my breath. It doesn't look good.
Congratulations!
You're phone is now a piece of brick!
Board failure!
If your phone goes to download mode you can repair it by jtag and if it doesn't power on anyway and it's still under warranty, you can ask them to change your phone or repair that.
Cause there's no way to understand you've installed a custom os

Then give details of the problem .

No download mode
No, it won’t go to download mode. I'll try the alternate battery. Thanks for the information guys.
Did you flash the right phone ROM?
Yes

Fairly certain I did but I'm pretty sure it's a moot point now. If I could get any sign of life, I'd use Odin to unbrick and go back to stock. Anyhow for now, it makes a great paper weight.

[Q] Empty Battery Bootloop

I had a recent soft bricked due to some "unknown" problems which I couldn't figure out.
Anyways,I was able to boot into download mode and successfully flashed the stock jellybean firmware via Odin.
Now the problem is that my battery is empty and the phone is stuck on an what I think is an "Empty Battery Bootloop" was the battery icon blinking every 5 seconds or so.
Any ideas how to revive it ?
PS : I am unable to boot into recovery as well.
I have attached a screenshot of the issue I am facing.
Ur screenshot says... 404 error
Re-linked.
Maybe something went wrong while you were flashing the ROM via odin. First of all did you tick Only the right options while flashing in odin?
Supposing you did,
1. Maybe the ROM file which holds information for your battery might be facing curroption.
2. Maybe the kernel (the default one coming with the stock ROM) was not flashed properly.
In either case, I would suggest trying to boot into download mode and try to flash the whole thing all over again. If the problem persists, flash a different kernel/ROM or both.
II'm pretty sure that should fix the problem though.

Tried flashing via Odin for like three consecutive days.Still no luck.
I have googled it and found out that some users were facing the same problem when their battery was completely empty and the phone wont start because it didnt had enough juice to boot up.You know how to solve that problem?

Just keep it on charging wid 0.7mA or a 1mA charger for few hrs... if still it doesnt work..use a usb cord to charge via lappy...
Also use someone else's battery to boot up... and make a wipe data via stock recovery
Charged with USB for about 4-5 Hours.I cant get hold of a 1mA charger here.Using another battery is nearly impossible for me since none of my friends seem to have a S2.
Any other phone which has a battery identical to ours? (Or a Samsung phone with 4 pins possibly.)

Nope. Don't try a battery not designed for the device. Asking for trouble.
Time to change it with a new battery or hook up with an external charger?
PS : Took it to a local mobile repair shop and asked for a universal battery charger.
When I gave him the battery,the first thing he asked was if the phone ever got wet.
He said there's some I don't know what on the battery due to licking it.
I recently replaced the charging circuit from a trusted Samsung shop and he says it's totally fine.
Seems like some kind of corrosion on the battery.Any ideas on how to remove it ?
Anyone ?

Frozen boot loop..frozen!? Tried everything..

Hey Guys, im desperate..
two days ago i charged my phone overnight as i normally do. Woke up and it was in SOD, which happens all the time (agni kernal, no fix yet).. Pulled the battery, but phone wouldnt boot. Turns out, it freezes during booting resulting in what appears to be a frozen boot loop.
Then i tried to plug it into my recharger, and it was showing a grey battery icon and was frozen on that screen always, the screen doesnt turn off, the battery icon isn't showing that its charging. doesnt change, just shows the same empty battery grey icon with the refresh circle-arrow in the middle.
I tried taking the battery out leaving it out for 5 minutes, draining the battery from the phone by holding the power button for 10 seconds, then trying to charge the phone. Same issue, only showing the grey battery icon when trying to charge and it never changes or goes away.
SO i tried to boot up the phone, but it wont go past the samsung text logo.
I tried entering recovery, but it just freezes on the samsung text logo.
I can not enter download mode either. So ihave no way to run odin from what i can tell.
Im losing my mind here, ive tried almost everything i can think of. And would really appreciate any help on this. It feels like a hard core brick.. I LIVE on my phone due to work and im losing money every day i dont have it. DESPERATELY need this. HELP!!
DatacomGuy,
A usb jig will probably be able to force the phone into download mode again so you can restore it with Odin. If you're up to it, you can do a Google search to get instructions on how to make your own.... or you can buy one online pretty cheap. Here's one on eBay (USB JIG) that looks good with good feedback from the seller.
Thank you.. Ill order one today and report back.
What could have gone wrong you guys think? How did the phone just do this?
I guess no way to get my pics off huh?
I hope the jig will work for you so you can restore the phone back to stock 4.1.2 and start over fresh.
I'm not sure what would have caused the phone to have started boot looping like that. My guess would be that something got corrupted.
There's a thread in the general section on how to Odin flash the stock recovery onto the phone so you can wipe cache and do a factory reset.... (EDIT: Click here to go to the thread) . This is a long shot, but if you can get the phone back into download mode with the jig, you could try installing the stock recovery and just wiping cache without doing the factory reset... then see if you can get the phone to boot up so you can recover stuff off of it.
As far as the pictures go, they may have been saved to the external sd card. You could pop the sd card into another phone if you've got another functioning phone laying around... or use a sd card adapter to mount it straight onto your computer so you can check.
The jig did the trick.. thank god..
The flashing stock recovery did not work. I ended up going back to stock firmware.. 4.1.2 i think..
Thank God i have this back.. Thanks SO much for your help.

That's great to hear. Too bad the stock recovery didn't work, but I'm glad the jig worked and you were able to fix your phone. :thumbup:
