[Galaxy S II Q&A, Help & Troubleshooting] Spud2233:
Sorry for reviving an old thread, but i have a solution that may help others out.

I have found a way to power the Galaxy S2 GT-I9100T from an external power supply ( i have also tested on S3 GT-I9300 and S5 SM-G900I).

My first step was to create a dummy battery out of perspex, you could use any non conductive material.

Make sure you include the alignment notches and keep it as close to the size of the original battery so it is a snug fit and wont accidentally fall out.

When you know the perspex fits you can start fitting the contact terminals, make sure you have the polarity correct and that they line up with the contact terminals of the original battery and the spring terminals in the phone.

Once you have the terminals fitted you can then look at powering up your phone, i used a LM2596 based DC-DC converter that i had laying around.

If you are using a variable DC-DC converter like i did make sure you adjust the output of the power supply BEFORE connecting to your phone to prevent you destroying your device.

My DC-DC converter is set at 3.88 Volts, this value seems to trick the phone into thinking it has a battery with greater than 40% charge that way you don't get the annoying low battery alerts.

How about taking your admittedly innovative idea one stage further.......

If you have an old battery laying around, why not (very carefully) remove the top part of it for use with your perspex replacement....this top section contains the overcharge protection circuit which would help to provide added protection to the device....it also has the benefits of the facts that the battery connection points are already in place and correctly aligned (it also has those alignment notches at either end).....imo, an improvement on an already good idea....

I got problem with my SGS 2 - after long on-shelf time battery drained to absoltely zero. My voltometer showed 0 on every connector. I was unable to charge or boot my phone (24h+ on charger, no signs of life). Dead, bricked, gone... Battery was relatively new (some months) so I didn't want to buy another one. Then I read Spud2233's post... and tried it .Well, kind of variation. I connected charger to phone's USB port and additional power (Motorola's dual port charger) to internal batterys connector (simly stripped old USB cable). Then battery was inserted and.... voila! After 2 or 3 retries my phone booted in and started to charge. I disconected additional power cable, phone is loading as usual. Battery revived!

Thanks for inspiration, Spud2233!
[Galaxy S II Q&A, Help & Troubleshooting] fpN3eqU:
Just registered to say thanks for this tip!

I too have had SII batteries go dead after too long, and the SII seems to be unable to power up without a voltage across the battery terminals. :mad:

I used a small variable power supply set to about 3.5 V. I trimmed some thin hookup wire until only a few strands were left and 'pinched' them between the battery terminals and the phone battery contacts. Then with a charger plugged in to the phone I was able to 'trick' the phone into turning on. Once booted the battery charged fine.

Note I think this should be done quickly as the phone and power supply will fight each other for as long as the voltage is placed on the contact, so I pulled the PS wires out (keeping the battery in) as soon as the phone was booted up.
[Galaxy S II Q&A, Help & Troubleshooting] anton_kg:
Thank you so much for the solution to my problem! I have purchased TWO batteries already and they both stopped working after drained to zero. I was blaming a charger or a quality of the battery. I found other posts suggesting to remove a capacitor but it wasn't broken...

Thanks to you, I have just booted my phone, pulled out extra power after couple minutes and it charging on its own now! (well 5% as I speak).
[Galaxy S II Q&A, Help & Troubleshooting] blue whale:
I am in the same situation with SII batteries go dead after too long.

I do not understand this part

''I connected charger to phone's USB port and additional power (Motorola's dual port charger) to internal batterys connector (simly stripped old USB cable). Then battery was inserted and.... voila!''

or this part

'' I trimmed some thin hookup wire until only a few strands were left and 'pinched' them between the battery terminals and the phone battery contacts. Then with a charger plugged in to the phone I was able to 'trick' the phone into turning on.''

how is this different than inserting the battery in the phone and then connecting the usb power supply?
[Galaxy S II Q&A, Help & Troubleshooting] fpN3eqU:
The phone won't charge the battery if it doesn't detect (sufficient) voltage. You can "jump start" the charging process by tricking it with a fixed voltage across the terminals.
[Galaxy S II Q&A, Help & Troubleshooting] blue whale:
so I take my dead battery, then

-take a usb charger+usb cable

-strip the usb cable to get two strands

-put one strand of the usb cable on the + of the battery

-put one strand of the usb cable on the - of the battery

=>the battery is charging

[or easier, I take battery like this,

put one strand of an electric cable on the +, connect this cable to the + of the phone battery, then put one strand of the electric cable on the - of the battery and the - of the phone battery

then I put the battey in the phone with usb power supply IN and the phone boots ???
[Galaxy S II Q&A, Help & Troubleshooting] fpN3eqU:
I wouldn't use a USB cable, 5 V is probably too high.

Yep, that's exactly what I did (except I used a 3.5 V power supply).

Once the phone has begun booting you should probably disconnect the "jump start" battery as quickly as possible or it'll fight the charging circuit.
[Galaxy S II Q&A, Help & Troubleshooting] blue whale:
but you agree that connecting the phone battery the charged green battery is like charging the phone battery [at least a bit]?

then I would just use the phone battery normally, by inserting it into the phone and boot the phone and finish to charge the phone battery.
[Galaxy S II Q&A, Help & Troubleshooting] fpN3eqU:
Not really, the SII battery will still be dead after a few seconds "charging". Getting the voltage across the phone battery terminals tricks the phone that there's a charged battery present so it will boot and continue charging it. Otherwise it gets stuck in something like a boot loop looking for the battery (mine did anyway).

If you could charge it separately from the phone then obviously you'd just do that. ;)
[Galaxy S II Q&A, Help & Troubleshooting] regsnerven:
Thank you for all your tips. I tried similar stuff, but I guess the voltage was just not right.

So I asked around to get a spare battery, which which I powered on the phone. It worked like charm.

I change the battery while the phone was running and tada! my phone was loading the "out of order" battery just fine.

Pretty much the same trick you guys did, but with less soldering and more quick magic happening ^^
[Galaxy S II Q&A, Help & Troubleshooting] blue whale:
I did just that to my s2 and his dead battery.

I was scared to go with ONLY a 18650 battery to charge the dead battery (no phone or usb charger involved) : I did not know if I should connect pole+ of the 18650 with pole + of dead battery (and pole - of 18650 with pole - of dead battery) which is the parallel scheme or the opposite, to go with the ''series'' scheme
[Galaxy S II Q&A, Help & Troubleshooting] treysis:
You were right to be scared. You should not do that. The dead battery might draw too much current. That could be dangerous. Read a bit about how charging of Li-Ion batteries works: first you charge with constant current (CC), which depends on the battery's design, once it reaches the correct voltage (4.2 V for a single cell), it should go into constant voltage mode, and then you have to know at what time or remaining current you shut the charger off. A good rule of thumb is to wait till the current drops to 10% of the charging current. E.g. if you were charging the battery with 1 A***, you should turn off the charger when it's down to 100 mA.

***1 A is just an example that would work for most modern phone batteries. However, this can be different! Ideally it's written on the battery.

Also, it's very well possible that in newer phones the battery will only output voltage if the charging circuit inside the phone allows it to. At least that's the case in notebooks for many years, and I don't see why it should be very different for phones.
[Galaxy S II Q&A, Help & Troubleshooting] Boltie:
All good, thanks!

I used a USB cable plugged into the phone and PC USB socket for power. Then I taped two AAA 1.5v alkaline batteries in series (provided ~3.18v) and used another old USB cable to connect to the +/- terminals on the phone. The wires were pinched between the battery and the phone terminals as I placed the phone battery into the phone. It jump started, I waited a minute and then pulled the taped batteries out to let the phone continue charging. It was showing 0% charge but continued to charge after whereas before it had just turned itself off.

Happy days! :)

I got that once too, on my X8. Try this:

Reboot into recorvey and do i factory reset, then reinstall.

Or

I did my first root this morning using KFU and ran into the same problem. I could not get mount access to get google market installed. It was always denied, even when I mounted first in KFU.

This thread: http://xdaforums.com/showthread.php?t=1569298 states that there is a new /system/bin/check_rooted binary. I assume this is what is blocking us from mounting the app directory in order to install the market. I tried the secured rom there (probably should have done the unsecured), and still didn't have access to mount.

Instead, I booted into twrp, and installed http://xdaforums.com/showthread.php?t=1439916. It says you do not need to wipe first, but I did anyways. After booting back in, google play showed up already installed in the apps. I logged in and downloaded mobo player to test it out, and no problems.

I have been having similar problems, I got to load into the google play store app once and then tried to download something and got the force close error. Since then I have uninstalled it multiple times and reinstalled and have never gotten it to work.

[Galaxy S II Q&A, Help & Troubleshooting] TheSaw:
Hey guys!

I have a weird issue with my phone, and after doing a bit of research I got a bit pessimistic, so here it is:

When I unplug my phone from the charger, the phone stays in "charging" state, which means the charging icon is there, the battery stats are not shown correctly, I can't plug it into my PC via USB, etc. It also doesn't enter deep sleep, since there is a vbus_present wakelock held, which is normal for charging.

I've read that water damage can be one of the causes, and if I think of it, I did have my phone with me, while I took a long bath. While the phone didn't touch any water, the air humidity was really high :), so I could blame this for the issue.

Do you have any suggestions / ideas?

Thanks!

It is the same for me when I dropped my phone into water. However, it is now normal again ( lucky me). For your case, I think it water damaged, I would suggest you dry your phone.
