[Galaxy S II Q&A, Help & Troubleshooting] pmpntl:
is there a part # on the USB charge board that says what revision it is?

Are people replacing their old 1.5's and getting 2.2's and that is fixing things??

confused.

--any pics of before and after replacements???--

I just bought one off of ebay and i'll cross my fingers that it will work.
[Galaxy S II Q&A, Help & Troubleshooting] alias_neo:
The replacements are for faulty ones, I think most have been ignorant of the difference in revisions. The main difference between the revisions are that the 1.5 is missing the 6pin IC (USB ESD protection) on the right hand side, near the ribbon, and has an additional diode. The Rev 2.2 has the ESD protection chip and lacks the diode.

Essentially the boards are the same but the Rev2.2 has additional protection via the chip on each pin, wheras the Rev1.5 appears only to protect the single pin.

From the date on the Rev.1.5A that I got and sent back it was designed/built in february of this year, much earlier than my phone was made, and it's possible that the main PCB might have changed in this time also to take account for hte modifications to that small daughterboard that hold sthe mic, speaker connector and USB port.
[Galaxy S II Q&A, Help & Troubleshooting] cchant:
I've sent an email to the website I bought mine from, tvc mall, and informed them of the problem. They sent 1.5 while I need 2.2. They said they would look into their stock and see if they had any 2.2 revisions and let me know. If they do, I'll post here.

Given my own tests I can't help in speculating if these are mostly (but not purely) Firmware related problems. Would be great if people could also post the following info, as well.

1. Baseband (aka. "Phone") version

2. Build/PDA (aka. "Firmware") version

3. Build date

4. Charge port PCB version (if known)

For the love of god don't use thinner/nail polish remover on a plastic device!

It melts all kinds of plastic, and the inside of the port is plastic and may be damaged, any spill will ruin the case too.

Just use the stiff plastic brush (you got from an electric shaver) or some other small brush, toothbrush may be too stiff.

And some rubbing alcohol. (t-röd in Sweden)

I have also been suffering with the USB port issues described in this thread:

Device not always charging even though charger plugged in

Device says that it is still charging even though cable has been removed

Battery temperature warning symbol when rebooting - have to use recovery mode reboot

Battery showing random charge levels

Battery icon staying at 100% until reboot then displaying random%

Screen flickering when plugged into charger at has reaching what it thinks is 100%

Screen flickering when plugged into charger with no battery inserted

I tried recalibrating the battery (lots of times), using CWM reset battery stats, apps from the market, leaving the battery unplugged with 30s etc.

I tried using a toothpick and electrical contact cleaner to clean the USB port and remove pocket lint etc.

I tried slightly pushing the 'tongue' of the connector towards the screen to try and aid proper contact with the plug.

I cried.

I then sent the phone to Samsung's repair centre and they have replaced the USB port and supplied a new battery.

Everything is fine now :)

I was the 8th SGS2 since tuesday which came in the repair center.

The phone gets hots, and outside temperature is cold, so it makes moisture in the phone.

This cause the phones power management to get fu up (SGS2 has a small battery inside of it, and that gets fu up). Only fix is replace hardware, but 9 of 10 times Samsung gives the fault to the customer. They say it has water damage and can't be fixed in warrenty...

Hi,

I have the same problem:

Since 2 days ago, the phone says it is charging randomly, even when it is not connected. It just lasted some seconds, but it said "charging" when clearly it wasn't charging.

Also, when i tried to shut down, it didn't, instead it rebooted, and stayed stuck with the battery and temperature icons. I couldn't reboot the phone, unless i connected it to a charger.

Also the battery was getting wasted twice as fast as normally.

This is similar to what many have experienced.

Today i tried to clean the USB port with some compressed air, and now IT STILL DOESN'T SHUT DOWN when i ask it to do so. But the difference is now it just reboots, and there's no yellow triangle and temperature icons.

So i could partially fix it, but still, i can't shut it down completely. it just always reboots.

Any new ideas?

I'd reall appreciate some help, as i don't want to take off the battery everytime i just want to shut down the phone.

Thanks !!

First... sorry for my bad english :p

(below explains)

I solved the problem definitely. Not is problem of ur hardware or usb port or usb cables or battery charger.:rolleyes:

The solution is very very easy.

1. Install "battery calibrator" apk on your sg2

2. Wait to your battery is drained (until it turns off)

3. Charge your phone up to 100%

4. Open "battery calibrator" aplication

5. Press button "calibrate battery" (with battery charger pluged)

6. Unplug the battery charger after pop up appears ;)

7. Repeat the process until your battery is totally drained

*** I repeated this process at least 4 times ***

*** My problem is 100% solved.... now i charge my battery normaly (without Battery calibrator aplication) and all is OK.

i have had this same problem since the last few hours

the battery suddenly started drainging and my phone went berserk. The drive mode got enabled and then my home key kept on bringing up some other home than golauncher. Than the phone wouldnt shut down..it just restarted. so i couldnt even charge it while off. After it went dead completely.. i charged it again..rather than charging with the battery icon... it just restarted..than as soon as the homescreen loaded it restarted again.. than went into a loop.. while it was at the homescreen it showed that it was charging wether the charging cable was connected or not...

so i tried to drain the battery comlpetely... and then kept it outside for a little while...

after that i noticed that it went into the turned off charging mode with the data cable connected to the pc... so i let it charge a little while... than when i connected it to the wall charger.. it started charging normally..

its going ok now... hopefully it will keep going like this... otherwise im ready to order the PCB connector from ebay..just to be safe...

I'm currently fighting this one with my Telco. Fortunately we have good consumer protection law here, so they'll be supplying me with a new phone shortly once I beat them around the head with enough legal documents.

All the symptoms mentioned above, cleaning the port didn't fix it (the second time it failed, cleaning it worked the first time).

They say it's moisture damage to the USB port. Heck it might be for all I know, but it's not from the phone getting wet, if anything it's condensation as mentioned elsewhere on this board. So I'm fine as far as getting a replacement goes.

What I would like to know, is how many of the people with issues had a case on their phone? Mine had a silicon outer case thing. 2 of my friends with these phones use them in much harsher conditions than me without cases and have had no issues. I'm wondering if maybe the case has caused the heat difference between inside and outside to increase to the point that it causes condensation?

Either way, Telecom NZ are being very, very difficult about it. Extremely frustrating.

further to the above, i opened up my phone last night and removed a dog hair which was caught in the back of the usb connector and tangled up in the microsolders holding the connector to the board. this has reduced the random behaviour, but not eliminated it completely so i'm just going to replace the board and be done with it.

What I did

I bought a broken Galaxy S2 cheap off e-bay, seeing that I could probably fix it based on the description of the problem. It gave out spurious battery heat warnings and would not charge from ac adapter, only from computer USB. It would also not turn on unless connected to computer usb, even if charged.

First I bought a new battery. This got rid of all the problems but then the spurious battery overheating warning returned after the first hour. Then the boot problem returned a little while after. Go figure. Maybe all the symptoms would have returned had I waited.

So then I installed the replacement USB cable which I got from e-bay here

http://www.ebay.co.uk/itm/Samsung-i...AU_MobilePhoneAccessories&hash=item3a6e458756

The seller assures me it's the 2.2 although I didn't really give it a close look before installing it. But it appears to work.

So all fixed now apparently - though I would wait 48 hours to be sure. Will repost if any further problems. One note of warning - I wouldn't attempt to take the thing apart without the pdf diagram entitled

Samsung GT-I9100 Galaxy S II - 07 Level 2 repair - disassembly.pdf

although you don't have to strip if down completely to change this part, just remove the motherboard, not the audio receivers - i.e stop after diagram 5 of section 7.1 and do not proceed to 6.

The only tricky part I found was working out how the rubber buttons on the side go back in - you sit them on the plastic backing and place the main circuit board onto them (very gently - if you 're forcing it you've done something wrong)
