I know, I know, another bootloop thread. I've been reading dozens of them and I can't find my problem, please forgive me.
My wife's phone was stolen, and so we bought a used one from a stranger after seeing a listing on a local sales site (gumtree). Bad call - they demo'd it for us, but we didn't power it off and on before buying. After parting with cash, we find the phone won't boot unless it's plugged in to AC power (and not USB). All it does is loop grey/green battery logos over and over. Sometimes vibrating, sometimes not, but it would never break the loop, except to enter download mode, unless I connected it to AC power.
If I did boot it, I couldn't do some stuff, like enable USB debugging - it flat out wouldn't allow me to check that box. So I checked the kernel, and it seemed to have a weird kernel installed, so I thought it was time to just re-flash with the official firmware.
Well, first I wanted to try SlimROM, but I couldn't get to CWM Recovery (which was already installed) reliably, and on the rare instance where I could get it to come up, I couldn't navigate to extSD where the slim files were, nor mount USB storage (the PC wouldn't recognize it).
So I decided to try and re-flash to stock, using ODIN and the official samsung FW that worked well on my own GS2. This worked, after a fashion - I could get it to boot if I applied AC power, but things were badly broken. It'd reboot a minute or two after the setup began, and so I was forced to suspect either hardware failure or something that survived a complete wipe and flash.
So I thought kernel. The only one I had lying around that I knew worked was an old jeboo kernel. I flashed it with ODIN, and presto - it worked! The thing booted and stayed stable.
But I still have that accursed battery loop when the phone's off, the battery needs to be yanked to keep it actually powered down. And there are other bugs, like the screen comes on after you turn it off with the power button. Just once, but now it can't be powered down and ignored - you turn the screen off and wait to see if it comes back on and do it again.
And it's confused about charging - this morning it reported the AC adaptor was a USB charger, and this evening it thinks both USB and the AC adaptor are both AC (in the battery info settings screen).
And the only way to get it to boot reliably now is to remove the battery and plug it back in, at which point it boots as normal.
So, after all that long winded four-hours-of-tears-and-anger story, my question is this: What's the battery boot loop all about? Why does the screen flicker constantly when it's charging via AC? Why does it take -twenty seconds- to recognize it has been plugged in to power?
I can't install CWM, it won't enter recovery or boot successfully (no loop, just hangs on the yellow triangle screen). Before I start randomly applying new ROMs via odin, I'd like to find out more about my problem.
Please, can anyone shed light on this? I thought I knew what I was doing but I'm coming up empty here.
Sounds like the USB board/port (tho it might be worse than that; this is what I'd replace first). Relatively cheap/easy to replace; but you do need to check which board is currently in the phone & ensure you get the exact same as a replacement - there's 4 different boards, get the wrong one & you won't fix the problem/waste time & money.
Search for similar threads, there have been detailed threads in Q&A over the past few mths, those threads should have the info you need.
There's also a chance it might be as simple as the battery on the fritz, if you're able, try another one.
But definitely sounds like the USB board (hopefully for you) to me
Thanks for the suggestion. Certainly the flickering while charging issue and the delay to recognize the charger being plugged in point towards a USB board issue, but what I can't figure is the reluctance of the unit to boot without changing the kernel. Wouldn't the stock ROM via ODIN have included the stock kernel? Why does CWM cause the unit to lock up during boot?
Last night the thing stopped flickering on AC and recognized the charger cable instantly - is this a self-calibrating feature? (My research of a thousand similar threads seems to suggest a lot of battery issues correct themselves). For the record, the phone did come with a second 3rd-party battery, but neither it nor my own original GS2 battery make any difference.
So... Yeah, I'm still not sure if this is a hardware problem, software problem, or both.
Also last night I followed a suggestion from another thread and loaded up touchwiz, changed the screen timeout and switched back to apex launcher, and the screen started shutting off as desired. This morning it doesn't work anymore, and the phone is frequently found with the screen turned on. =/
Ok so by flashing full stock rom that practically eliminates the software side of things. Now do what mistahbungle said. My money is also on the usb board. I had to replace mine recently. Click the link on my signature, from there you can get onto a guide by keithross39 on how to DIY if you choose.

'practically eliminates' indeed. I still can't work out why I had to flash a new kernel to get it to boot. =/

Do you want help, or do you want to continue doing what you think will fix the problem? If you're having the same issues on full stock, it indicates hardware issue. The software won't work unless the hardware is functioning correctly. Let me think, what did MistahBungle say was the problem? Oh that's right. The USB board. Hardware.
Oh, sorry, I thought we were having a conversation. Should I not talk until I get the replacement part?
I'm not disagreeing, I'm fully prepared to accept the USB board is part or all of the problem, but I still wonder why etc etc.
OK....so....firstly, flashing a standard single file firmware won't fully wipe the previous software.....all it does is overwrite what it needs to (leaving who knows what untouched). The easiest way to regain a 'clean slate' is to flash a 3 part test firmware which DOES complete a full wipe during the flash..... @Hopper8 s guide provides a link to this test firmware and full instructions as to how to install it.
Secondly.....hardware faults can/do cause unexpected operational issues......some of the issues you describe were appearing on my wife's S2 before I replaced the USB board on her phone (they disappeared afterwards). As @Hopper8 has mentioned, his guide includes a link to my guide concerning the replacement of this part. I personally would hold off doing any more Odin flashes until you have replaced the board......if the USB port fails during a flash (because of a faulty board) you'll end up in a 'whole world of hurt' that will be infinitely worse than it is now.......

Thanks to both of you for the responses. I've taken the phone to a repair shop and they swapped out the USB board to no avail. =/
Given what you've already spent on it (cost of phone + replace USB board), if I were in your situaton, I'd be cutting my losses & put it down to experience rather than replacing the motherboard (with a 2nd hand board from a 'donor' phone), whilst that's nowhere near as expensive as paying a service centre to put a new board in, it's still likely to cost you >AUD$100. If you can get one for a lot cheaper than that, maybe it would be worthwhile.

Or...as first measurement, you clean the pins briefly and bend the holder slightly back to the center.

By 'holder' do you mean the USB port, or the connection inside the phone between the USB board and main board?
It's not a physical problem, at least in the USB port... I mean, we put a new one in it and nothing changed.

Ah the usb board had already been replaced? Okay then forget about my proposal, sorry.

So the next step is either a motheboard replacement or the bin.
I realise this isn't what you want to hear, but think logically about it...You bought a 2nd hand phone from someone you don't know/had no idea what they'd put the phone through before you bought it, it crapped itself shortly after, giving no indications whatsoever the problems are firmware/software related, and showing a number of symptoms which indicate something major is wrong hardware-wise.
You tried the cheap/obvious & that didn't work, one way or another you need to bite the bullet (both options involve you spending a not insignificant amount of money in all likelihood, unless you can score a donor phone cheap).

Way ahead of you. Ordered a new (NEW this time) phone. Will be selling the S2 to the next guy, along with the caveat "Sometimes the screen comes on." Will lose a few bucks, but it'll go into the old logbook of lessons well and truly learned. ^_^
Thanks for your help.
My phone wouldn't power on so I got it repaired at a phone repairs shop. The guy there thought there was a software error because he saw the error triangle on bootup. He was mucking around with it in download mode when I got there, I said not to worry about it, paid for the repairs and left.
The phone will not boot, and will not go into recovery or download modes with the respective key combinations
UNLESS
I have it plugged into a power source, in which case I can enter download/recovery mode, but when I try to boot the phone I just get the empty battery picture with the loading circle appearing periodically.
--- Possible solution: bad battery
I have flashed CWM onto the phone using odin in download mode and have flashed .zip roms that were previously working before this debacle, but again the phone won't boot onto the newly installed rom.
I have tried flashing the correct stock rom using odin but the phone won't boot this way either.
When I take the battery out and connect the phone to a power source it is non-responsive.
Apart from a batter problem (which I will be able to test tomorrow), what could be the cause of this problem, and how might I be able to fix it?
Sounds like a JTAG (but don't get your hopes up) or a motherboard replacement job (more likely) to me. If the phone won't boot at all/shows no signs of life, something is majorly wrong. As to what that is, nobody here could tell you that with certainty because we don't have the phone in front of us, but if it's not booting at all either the NAND is buggered or something else on the MB has crapped itself.
Cross your fingers it's just a simple battery issue, but it doesn't sound like it.

What does being able to access recovery mode/download mode contribute to this? The phone works to a degree, it seems, it just won't boot to an OS.
How might I go about troubleshooting the hardware?
(Might as well use this as a learning experience)
Right. Sorry. Just re-read your OP. Still sounds like the NAND is stuffed, which explains why you've tried flashing flashing stock/CWM & phone still won't boot normally. One thing you could try is search for Hopper8's 'Odin troubleshooting' thread, and flash the 3 part firmware linked in that thread. If the phone still won't boot normally after that, it's pretty much a certainty that you'll need to replace the MB at least, which leads to the next paragraph...
Also, if you find the 'booting when plugged into charger but not with battery' thing is still happening even with a new battery, that suggests whatever circuitry is responsible for taking zzz's from the battery & powering the device is (also) faulty/damaged. You could also try the obvious & clean the battery contacts with some isopropyl alcohol. The most common charging/power type problems we see here is the USB board/port dying. But if the phone is slightly functional whilst on charger, it probably isn't that, still might be worth replacing though given how quick/cheap/easy it is to do. There could be a short/whatever causing at least some of the problems, and it wouldn't be the first time a faulty USB board has caused that/manifested itself in less obvious ways than what we normally see (I.E causing the problems you're seeing rather than causing intermittent charging problems or phone rebooting randomly on its own or whatever).
In that case, try the service manuals for the device; these have been posted here before & can also be found with a Google search. They have detailed schematics/parts lists/walk throughs of the most common repairs w/pics, and might help if you want to have a go at fixing it yourself.
Thanks for the response.
I'm in the process of downloading the three part firmware to test later in the night.
Providing that fails, I'll look into part supplies and start researching how I can, if at all, repair this myself.
On the topic of faulty USB boards- I had my phone serviced a few months ago for just that, and it worked fine, but in the weeks leading up to this event my phone HAD been rebooting itself semi-regularly, although I put this down to a software issue rather than a hardware issue. I'll get my hands on the service manual for the I9100 and start reading up.
In the meantime I can just get a cheap burner Nokia that won't play up on me for the next 20 years.
Interesting. In that case, given the other alternatives are more expensive (assuming the 3 part firmware & new battery doesn't fix things), it may just be a case of another dodgy USB board & you might want to start there.
If you can't find the manuals anywhere, let me know & I'll see if I can dig them up from an external drive I have stashed away somewhere (don't have it handy now, but will dig it up tomorrow for you if necessary).
Yep, unlike current technology, old phones like that just seem to work no matter what you throw at them
The three part firmware flashing has moved things along slightly- after it finished the stock SGS2 boot screen appeared for a second or so and while leaving it on the charger it will cycle between showing the grey loading battery and an android with a loading bar underneath, which is progress from before. It is still unresponsive when disconnected from the power- I have procured the service manual and will look into disassembly/diagnostics when I have some small enough tools. I'll still try using a different battery when I can, but it probably isn't the issue.

Hey Everyone!
I have an S2 with some trouble...
The phone was not charging at all, kept discharging even when connected to power, so I suspected a Charging system failure...
I proceeded to get a new charging port, and the battery would charge up to 60% and give an error (Battery Disconnected), tried a couple of charging times, never got a good battery life, phone was shutting down unexpectedly...
So, it was time for a new battery, bought the battery like 3 days ago, inserted the battery, tried powering on the phone (hoping the battery would hold some power), it didn't power on at first, kept doing my stuff, and like 3 hours later, I connected the phone to the computer to get some power, and it was powered on already...
Now, the battery life is quite good compared to what I used to have with the other battery, but whenever I power off or restart, the phone will keep turned off... If I connect a charger, the phone will boot and tell the battery is 100% charged...
Now, If I shutdown, remove battery, put back on and turn on the phone, it will boot from time to time, getting a massive battery drain, powers off by itself, connecting the charger without power on, the phone will display a full battery...
Any help will be appreciated!

If I remember correctly, updating through kies would repartition the device, and I dont know if ICS would be compatible with that (used disaster Rom before on another i9100 i had), also, I ignore the method used to update
Yep, do a clean install of stock in the first instance & test. Are you sure you bought the exact same revision of USB board that was already in the phone ? Often problems that persist after replacing the USB board are caused by this. If you didn't, you probably want to buy another USB board & replace it again, but use the exact same revision that was in the phone initially. Check KeithRoss39's guide in General for the info you need.

K, will try a stock ICS, feel a lot more confortable with it for trying out the battery stats...
As for the USB board, originally had R2.2, only R2.3 is available everywhere I ever looked for it, will need to order from somewhere else, but the shipping will cost like 1500% more than the actual board, will keep digging around the junkyard
The difference in the board revision might well be causing your issues, but hopefully it's just something funky in the rom install you've currently got. If it's OK on stock, do a completely clean install of your custom rom & test that for a bit.
And if it's not OK with stock, you know what to do.
Hi!
Have you checked your battery? Maybe your battery has some problems. Actually, one of my friends had the same problem..... He purchased a new battery and a new charger for his S2 and fortunately, his problem was gone!
Please thank me if i helped you!
'So, it was time for a new battery'
And so the 'nobody reads threads before posting on XDA' thing continues...
As @MistahBungle says.....get that board replaced for the correct version. I would personally avoid Odin flashing a phone that I knew to have the incorrect USB assembly. I'd also advise you to think long and hard before flashing stock ICS to your phone......if you want to know why.....do a search for "emmc brickbug".........
This might be my S2 or it might be my W, but it's definitely CM...
Before one month ago a strange problem appeared.i flashed different roms and kernels but a few days later after a complete dischargeof the battery when I completely charged my phone with the charger it tried to reboot and it didn't pass the boot screen.This problem was solved only with a full wipe and a reflash of a rom.But if I try to use the charger instead of pc to charge my phone or if I complete discharge it sometimes It will not boot.i tried a lot of different roms and kernels without success .any ideas what causing this problem?

Probably the USB board/port. KeithRoss39 has a guide in General (not stickied; search for 'replace USB charger board') which will enable you to replace it yourself quickly/easily/cheaply (<US$15).

Ok thank you very much for your answer.Do you think that it could be the charger instead of usb board/port because it seems that if i try to charge it via usb cable from pc or if i try another charger it will boot normaly but the problem is that i don't know for sure because i only use my charger when the phone is completely discharged (turned off) ,i usually have my phone connected to pc all the time,so i also suspect that it may be the reboot that causes the phone to boot loop and it may be not connected to the charging proccess at all.What is your opinion ?
Also is there any way to test my usb board/port to see if it working correctly before replacing it ?

I tried both stock and aosp roms but with no luck.
I tried different chargers but the problem doesn't appear every single time so i don't know for sure if the problem is from my charger.Sometimes it boots normaly with mine too.
I didn't try to wipe battery stats from recovery but how it could be useful ?I couldn't find a lot info for that...

Might be the charger, so try a new one if you like. But don't be surprised if you end up having to replace the USB board after. The issues you described with booting/not booting sound like symptoms of the USB board on the fritz.
When the boards start dying, they rarely stop working completely (at least initially), and often show a couple of faults, but work OK in other ways (might be able to transfer data OK but can't charge as an example, and so on).
As a test, do a completely clean install of stock & test it for a few days, if you see the same thing, it's fairly likely the hardware fault. Up to you which way you want to go in that case, but I'd be replacing the board.
Edit - In light of your post just now which crossed with my reply, it's definitely the USB board. You've tried different chargers, you've tried stock, that seals the deal as far as I'm concerned. Put it this way, if it's not the board, it's something else hardware-wise.

Ok i will start testing then and replace the usb board if needed.Another thing that confuse me is why the phone boots with a full wipe and re-install of a rom ?Also in what way the USB board can affect the booting proccess?

I don't think that anybody outside of Samsung themselves would be able to tell you why one of their phones acts the way it does.....they know their hardware and the way software interacts with it in a way that nobody else can.
All I know is that I've handled TWO S2's with faulty USB ports, and they have exhibited various symptoms as a result.......
1) phone displayed charging icon even if it wasn't plugged in.
2) phone NOT charging even though it WAS plugged in.
3) PC/Laptop not recognising phone when USB connected.
4) phone randomly shut down.
5) phone would not boot unless boot option in CWM selected.......
I could go on, but you probably get the picture.
These issues stopped occurring on both devices as soon as I'd replaced the USB assembly......
Choice is yours fella, but I know what I'd be doing.

I replaced the usb board about a month ago but i still have bootloop issues that appear randomly.
I also have some other issues now.
First of all when i try to transfer files from/to pc the copy procedure will stop at some point and then windows does not recognize my phone or a pop up window appear asking to fix my drive but when i try to fix it says that the drive has no problems.
Apart from that if i try to remove the battery and then put it again with the charger still connected to the phone the battery percentage fall from 100% to 10%-15%.
I dont know if all these problems are related but it seems that the usb board is not responsible for these issues because i have the same problems with 2 different boards.Any ideas what else hardware-wise might be ?
Thanks in advance !

I read carefully the OP and the replacement that i bought is the same 'rev' version with my old one.So is possible that the new usb board is faulty too ?
Is it possible to be something wrong with the internal SD ?
I want to mention that i have used a PIT file posted by @metalgearhathaway to increase data partition but the procedure was successful...
The only reason that i mention it is because then i had the faulty usb board and i used ODIN for the procedure but it passed all stages succesfully.
Mate.....remapping the partitions with a pit file is a pretty major thing to forget to mention.....
It's pretty advanced and/or risky to start messing with pit files.....it's also something i've never done, so i'm unsure of the consequences.......apart from the obvious 'permabrick' risk.
I don't even know how you'd revert to the factory set partitions if you needed to.....though i'd guess it'd involve flashing another pit file. All the issues you've previously mentioned (apart from the battery) *could* have been caused by the pit file and that being the case, you're lucky it wasn't a whole lot worse. As for the battery, that could simply be the fact that batteries do fail, and if yours is the original, this is probably the case given the age of the phone and the fact that Samsung only offers a 6 month warranty on the battery anyway.......
Sorry fella, but as there's a pit file flash involved, you've moved into territory that I can no longer advise on........

Hello,
I have Galaxy S2 and having some charging issue. Yesterday, when I plugged it in the wall charger, it didn't get charged (i.e. even the flash on battery was not coming up) and when I tried to restart the phone, it powered off but didn't switch on. I tried holding the power button to turn it on but it didn't. So, I pulled out the battery and left the cell for some time like 20 mins or so. After re-inserting the battery, it turned on but still was not getting charged. I tried to change the USB cable as well but nothing helped. I then tried to charge it via my Laptop it actually started the charging process but with error on Laptop saying "USB Device not recognized".
Today, I tried the wall charger again and here's I found something: when my phone is ON and I plug it in the wall charger it doesn't charge but as soon as I turn the phone OFF, my phone starts getting charged (Battery image comes on screen which usually comes when the phone is off). So, that's how I am charging my phone.
I went to the repair shop today, he said it's a charging port issue on which I have some doubts that why it is even charging in this way if it's a port issue. I just want to make sure if whatever he's saying can be somewhat true.
Can you please help me out? I would be really thankful to you.
I look forward to hearing from you soon!
Thank you!
PS: I tried to search about the port issues but I couldn't find anyone having this kind of issue so please!
The issues you have mentioned really do all point to a faulty USB board......it is common (with a faulty board) for some functionality to work while other functionality is lost. The part itself costs pocket change and is reasonably easy to DIY replace......
If you want to go down that path, check my profile for threads I've started.....you'll find a guide explaining exactly how to do it.
Just make sure to read and note the section on 'rev versions' it is VERY important to get the correct one......
My wife says I'm a phone geek....She's probably right
