hey,about a week ago I flashed my galaxy s2 with Resurrection ROM,everything went great,I also wiped emmc in the recovery(before I knew about the hard brick bug)
anyways everything was fine,restored via titanium backup,after about an hour I wanted to restart my phone,so it turned off,but never turned on,it won't respond to charging,usb connections won't go to download mode nor recovery..just makes some heat (as it was turned on)
so I took it to a well known repair shop and told me he could revive it with a J-Tag
but I'am just worried :s
what could be the problem?
What could the problem be ? Without opening your phone up & having a look/testing how would we know ?
Sounds like something on the mainboard or the USB/charging circuitry might have died given it died suddenly & not while you were in the process of flashing something/similar, though if he's telling you it's fixable with JTAG then he obviously thinks it's a NAND issue.
Take it to another repairer & get 2nd opinion (or a 3rd, 4th, etc).

No more charging
My SGSII stopped with charging!
The battery was empty so i wanted to charge it, but the big battery never showed on screen
I tried different charging methods (wallcharger, usb) and used different battery's (standard 1650Mah & Extended Battery Kit 2000 Mah)
Is there something i can do because its way to early to buy another phone!
And just because i want to have it fixed

My phone dead too.. Was using NeatRomLite and there was no issue with it.. And today... *sniff sniff*.. in the middle of using the phone, it got stuck.. I pulled the battery.. gave it 2 min.. and tried to power it on.. nothin.. no download mode, no recovery, no charging indicators.. nothin.. it has as much functionality as a piece of rock now :crying:
Any updates on your S2's???
today i checked my phone and within an hour the battery had gone down from 70% to 30% and was hot reading 48 degrees celcius on widgetsoid monitor. i rebooted and it kept on draining till it got to 0 and turned off. once i got home and tried to charge through USB and A/C but nothing happens, the phone wont turn on or charge, blank screen. i saw it flash the battery charging icon for about a second but it went away straight away. about a month ago i was running cm9 and then flashed 4.0.4 to have a look at the differences but not long after flashed siyah kernel with odin and restored my cm9 cwm backup. i have been on cm9 and siyah kernel for a long time and thats what it had running today. ive had usb and a/c and misc charging current set to 600mA for quite a while as well, and when i charge the phone in my car it always gets a bit hot on the back.
is my phone dead from hardbrick or a problem with the usb charging circuit?
i have enquired about warranty where i bought it from and now waiting to hear back from them.
Hi i have a Galaxy S2 with some strange issues attached .Firstly upon leaving overnight on a full charge it shows 100% charged but when unplugged from charger it instantaneously drops to critical and dies minutes later. Also the USB will not charge or connect to kies or register as a drive since the battery issue started . I have bough replacement batteries incase of an overcoooked original and same thing on all three.
The phone is on orange and is running a stock rom gingerbread 2.3.3 and is unrooted never been messed with or flashed and im the only owner .
Could this be a potential board fault ?or could it have in some way faultered on the firmware somehow with an easy fix
cheers in advance guys ..

First it sounds like a battery issue.
But if you checked with different batteries and with all you have these issues, it really seems to be a hardware issue in the phone ... maybe the battery stats chip, or the controller for charging (from power and USB plug).
If you are still on warranty, go to the store/service center and ask for a repair or replacement.
Good luck !
You can also try to clean phone battery connectors.

Hi all,
I have an AT&T Samsung Galaxy S 2 (i777). It was rooted and running CM 10.1. A few months ago it started to have charging/USB port issues. Some of the symptoms:
-Sporadic charging (starting and stopping)
-Required USB jiggling to get it to start charging
-Sometimes wouldn't charge at all until it died, then would eventually charge while powered off
-Would not shutdown (only reboot, even if the battery was removed)
-Randomly started "car mode"
My initial thoughts on this were USB port issues. After doing some research on people with similar problems, I tried cleaning the port with alcohol, toothbrush, compressed air, etc. No avail.
Eventually the phone just stopped charging altogether. At this point, if I left it plugged in, it would sit in a continuous boot loop (boot, get to lock screen, realize it has no juice, shutdown, rinse, repeat). After a few days of attempting to charge and just having that happen, it went black and has never turned on since.
To try to solve that, I bought a new USB port flex cable on eBay and replaced it, assuming this would solve all my USB port issues. I tried to be as ESD safe as possible and also not break anything in the phone, but after replacing the board, it still wouldn't boot.
Next step- bought a new battery with an external charger to skip the USB port altogether and see if the battery was shot. Charged up the new battery, popped it in, nothing.
I'm at a total loss. If it started as a charging problem, I don't see how the problem could have been anywhere but the flex cable board or the battery. Does anyone have any ideas about what might be going wrong? I would REALLY appreciate some insight.
Thanks!
Maybe the repeated loops damage it

Did you ever find a solution? I'm in the no charge boot loop after letting it die last night.
I have not seen previous usb problems at all. I suspect that my battery got over-drained, but then I've got the same symptoms as you and you have a new battery. I can get it into recovery but t won't stay on in CWM for long enough to fix permissions, which is the only thing I've tried so far in CWM.
Thanks
If i was in your place i'd have taken it to the nearest Samsung Service center and let them fix it for me.
I think the fluctuation in power may have damaged your phone battery point from where it takes power from the battery and charge it.
Maybe it has damaged the motherboard.
We cannot say anything in this situation.
You should just take it to your nearest service center.
Best of Luck
OK, wiping Data fixed it.
Thanks for your reply. This problem just started this morning with no previous issues, doing the looping part of your problem that I quoted. so it's not a question of what I might have done.
But, for others encountering my part of it, here's what I've done and learned so far today.
As I looked into things elsewhere on the , it seemed to be a software problem. Luckily, I have another Galaxy (Exhibit) that's similar battery and I was able to put the charged battery from it into the SII. The SII booted and worked fine but did not charge. I put the SII battery into the Exhibit (sorta fits). It took a charge.
This confirmed to me that it's not the battery. It must be the phone perhaps USB port or more likely "firmware" since problem started abruptly after draining battery down.
I then wiped data on the SII from CWM/recovery and rebooted.
SII is now charging again. Stock battery is back in and working.
Time will tell if all is well, but here's what I think happened:
1) battery drained down to zero while unplugged
2) plugging in and starting up phone immediately threw something off in the battery stats at a low level...that kept it from charging even when turned off. Or rather threw it into a loop. Don't really understand this stuff, but may have to do with physical things that happen in a battery when the cells drop down way low and then the voltage feedback they give to charging circuit.
3) charging battery in another device (gingerbread, by the way) got the battery out of this, if battery had been a contributing factor,(or just a trigger) it was back over the hump.
4) wiping data fixed the charging, so I conclude it was a charging circuit data issue triggered by an ultra low battery.
Hope I'm over this problem and hope that it helps somebody else. If you run into this yourself with no previous USB or hardware issues, I'd suspect software before hardware. If I had only one battery and no way to charge it externally, I would suggest get one of those simple universal clip-on chargers to bring the battery back up and then go into CWM and wipe data.
UPDATE: It's stopped charging again. It's no longer looping since I got the battery charged up, but not right either. As soon as I plug it into a USB, it boots itself without powering on.
I guess that this is looking more like a physical USB issue now. Weird that there's been no previous sign of trouble before today.
UPDATE2: I cleaned USB port but no help. Then I bent the USB contacts towards the screen and it is charging now again. I'm ordering a replacement USB.
I should add that I'm running Shostock Jellybean, older (not current) version with it's associated Jeboo kernel. Don't know if it matters.
I wish I'd seen your post sooner.. I had exactly the same problems back in January. Took all the same steps you did. In the end, an 8$ USB flex cable from EBay solved the problem. I think you'll have luck with that:thumbup:

hey, I'm experiencing the same issue slightly different.
-Sporadic charging (starting and stopping)
-Randomly started "car mode"
-plugged in the charger while the device is switched off, it automatically turns the device on.
-If the cable still plugged in while the charger removed from the main current, it shows "Charging stopped. High voltage"
-From yesterday, it doesn't charge even. Only way to charge is, connect the charger first and then Restart the device.
Then only charging continuous.
Can anyone help to solve this? Is this a software issue?
Thanks!

Also, there was this issue early --> when I charge it from the laptop, the USB mode doesn't switch on. It just charge the phone only.
But now it's not even working like that.

hi, my s2 wont charge. It just shows up charging when plugged in but it doesnt charge at all. and it overheats too much while plugged in. What is that flex cable you said, is it the one that connects the charging port to the motherboard? were you the one opened and replaced it? thanks
I have in my possession 2 galaxy s2 i777s one of which was thought to have a charging problem which is why we got the new one. Once i got the new s2 i tried to put the new battery in the old phone and it not only powered up but it also charged. i then put the old battery in the new phone and it wouldn't charge just like before, i keep getting a boot loop where the battery symbol would flash then go away periodically about 15 seconds apart i would guesstimate, this happens for both phones with the old battery, but both phone charge the new battery. I came to the conclusion that the battery may be the problem and set out and bought a new battery and gave the old phone to my mother thinking problem solved, only to discover the problem still existed, replacement battery wont charge same boot loop. Thinking lightening did strike twice and the battery was faulty i returned it and got another one same problem, boot loop when charging or connecting the usb to the PC. I tried the battery in my new phone same problem, i looked at the specifications on the battery to see if they were the same and yes they were exactly the same:
1650 mAh,
3.7 li-ion
6.11wh
made in china
i have MULTIPLE usb cable that are compatible and MULTIPLE chargers that are compatible and i have tried them ALL. a person suggested i take the battery out plug in the phone then place the battery in while plugged in, didnt work. i tried cleaning the contacts on the battery and the phone itself and nothing, the new phone is rooted but the old one however was bricked in an attempt to root then factory reset, i dont know if this plays a part in it, but remember the battery from the new phone charges in both phones and the the replacements dont charge in any. i had tested the old battery in the new phone before it was rooted or had any apps or anything on it and it did the same thing, boot loop.
any suggestions?
im new to the whole do it yourself root and rom thing so please keep that in mind when tossing certain phrases around.
Edit:
ok after searching some more i eventually found out the reason for this was because the battery I bought was incompatible, though the guys at the store said the battery would work for the i777 which it did, it turns out there is something different about the standard of which the battery was built.

Based on everything you've said, I would strongly suspect bad (or incorrect) batteries. You must have I777 replacement batteries. Ones made for the GT-I9100 will likely not work. I suspect that is your problem.
Hello. I just bought a s2 i777 unlocked from eBay and i have been having charging issues:
when i unboxed the phone there was no battery juice available and would not turn on. I connected the phone to the default charger(ETAOU10EBE) that came with it and let it charge for 30 minutes and powered it up and then let it charge. i was not home when it was charging...so when i got back 3 hours later it had stopped charging at 74%.
I also noticed it detected the AC charger as USB PLUGGED. I used my nexus 7 adapter and after more than 5 hours it reached 100%. the next day i rooted the phone by flashing siyah kernel and flashed shostock3 4.0( it was on stock 4.0.3 before flash). here i noticed that with any adapter or cable i use the phone takes a lot of time to charge and does not get past 70%.
The phone showed it was charging but actually it was discharging. i powered off the phone to charge it but after sometime when i turned it on to see if it charged the battery the battery has lost all its charge in less than 15 minutes while the phone being off. I searched about this problem on the internet and some people are saying it might be a faulty battery or DAMAGED USB FLEX CABLE. OTG is not working also. i can use my usbdrive on my nexus 7 correctly but it does not detect on the s2. I am thinking the problem is with the USB FLEX itself.
OTG worked before i flased shostock3....
i also reflashed a rooted stock 4.0.3..but that did not solve any problem..so i flashed shostock again. i even flashed pure stock i777 jb 4.1.2...it booted the first time but as soon as i plugged a usb cable to pc or ac it turned off and kept on showing flashing charging battery...so flashed siyah kernel again via ODIN and restored a shostock nandroid backup. And now the phone do not get charged at all and OTG also does not detect,
Any suggestion is greatly appreciated.
i would gladly ship it back to the ebay seller for another one but shipping is high.
UPDATE: The problem was solved by replacing a USB FLEX CABLE...

Well yes, but if you can do that, it may be the most inexpensive way. One other possibility is that you have a bad USB port in the phone. You can replace that yourself, but you will probably pay as much for the replacement part, and then there is no guarantee it will correct the problem. I have seen several people post that they tried to replace the USB port but that it was not successful. Sending it to a reputable repair shop is also probably not practical or cost effective. So I say, get a working phone from the seller if you can.

creepy's probably right (a usual occurrence), but it could also be as simple as a bad battery. Buying things like this second hand can sometimes give you trouble like you're having, because you don't know what's really OEM or some shoddy off-brand. Another option for you would be to get a cheap battery that's been confirmed to work perfectly on the i777.
Several of us are using this $5 battery from Ebay; it isn't 22000 mah like it promotes (it's more in line with the 1650 that shipped with the phone), but I'm using it right now and have never had any issues. If you want to read further about those of us who've used it, read this thread starting from here.

The seller described the phone as new....it looked new to me when it arrived but it had screen protector perfectly aligned on it...i had the charging issue since day 1. I thought that the battery was new and needed to be broken in...hence the long charging time. The seller refunded me the $9.98 i asked for the defected AC charger supplied(it showed up as usb plugged in any device).
I already contacted the seller several times and after i got his/her approval i left the device at a repair shop for verification of the charging issue....will see how it turns out....i cant buy another battery as it takes more than 30 days for items to arrive here in mauritius...i asked a friend to lend me his s2 battery... Still no sign of him...lol
The local repair shop is taking around $35 to change the usb flex and other short-circuited parts....did you guys had any problem with your usb flex???
And can you plz guide me here : what is emmc superbrick bug?? the 4.0.3 stock rooted rom i flashed had this bug in it...the OP warned about it...could this bug cause this hardware problem i am facing?

I had a problem with the usb flex, I bought two of them on amazon or ebay (I can't remember), did the replace my self and my phone is back on business
4.0.3 has the brick bug, don't perform a factory reset if you're on stock kernel.
I don't believe that bug is causing the issues
