I received a micro USB jig for the Galaxy S2.
In order to test in (my phone works normally with the retail kernel in it) I turned it off and plugged the jig into it but it booted *normally* NOT in download mode.
Is this normal ?
Your JIG is broken probably
Try turning it off, pulling out the battery, inserting the JIG and putting everything back in there.
Faulty JIG, the 301k or 300k resistor is not on the correct pin (4 and 5).
when you put in the jig, you don't need to push any hardware buttons. if you press power, it might boot normally, but if you let it stay off, then plug in the jig and wait for about 10 seconds, the download mode should appear. if that doesn't happen, indeed i would agree that probably the resistor or its placement might be faulty.
Thanks,
I'll try to open in and check if the contacts are not broken.
or the resistor is not 301k. You can check it with a multimeter.
I hecked with my meter, it appeared 300kOhm, which is correct (a few % error of my multimeter allowing).
I took a few pics pf the jig. I saw a very smapp component (probably the restistor with a print "3013" (or "E10E" uside down ?).
But I am not sure whether the pins are correct.
It is on the right side seen towards the socket and the wide side of the plug on top. I don't know whether this is pin 1 and 2 or 4 and 5.
Does somebody know this?
*** EDIT***
I saw a poor soldering contact on one side of the resistor. I held very carefully a hot soldering iron against it and saw it soldering.
After cooling I tried again and YES !! it booted in download mode.
Anyway thanks for your help.

interesting pictures anyway!
I have one of these and also did wonder how I might test it - don't actually want to use it in anger unless I have to!
So, switch phone off, plug this in and watch as phone comes up in download mode. What then? Just switch it off and remove the plug or just remove the plug?
I accept this is a newbie/clueless-type question - apologies in advance. In my defense, my SGS2 is back with the suppliers where it appears to have gone "missing"

As soon as it boots into download mode you can remove the jig. To turn it off I normally just pull the battery. I think holding the power button might work as well but I never tried, so don't take my word for it.

The only way to get it out of 'download mode' is removing the battery (as the power button does not work then) and installing it again and then power it on normally.
I have got out of download mode using the power button numerous times. So you don't have to pull the battery.

Same here, using the power button which just needs to be held for a while until the phone reboots.
Sent from my GT-I9100 using XDA Premium App
I just made my own jig with a breakout board plus a 100k, 200k and 1k resistors in series
Booted into download in under 2 seconds, and i turned it off as I always do from download mode using Vol-Up+Power.
If anyone has problems with making your own jigs, you can buy them from amazon for around £4-£5, if you're worried about the supplier, I think that amazon dispatches them as well.

Really? Cuz Ive been turning it off using the power button after using the JIG. you do realize it takes +/- 10 seconds for the power button to work in download mode right? Its to make sure you dont accidentily switch the phone of when hitting it.
So do not pull the battery, use the power button. Its safer and your hardware will like it better.

I tried this recently and all was ok - except for the message on the screen saying DO NOT POWER OFF. I waited for a while before deciding it was ok to pull the power - despite the message.
I'm sure I should have known, but hopefully this will help others who are experimenting ..

Hello,
a few days ago my HD2 just froze and I had to press the red restart button. I thought it was just a random freeze but my HD2 wouldn't start up anymore. So I pressed the reset button a few more times, tried taking the battery out several times and then eventually it would work again. I was able to start my HD2 and use it for 4-5 hours. Then I had the same situation occur again - it froze and didn't start up. I was able to start it once again but it froze after 20-30 mins this time. Now I can't seem to start it at all.
I've tried pressing the hang-up-button and the volume button at the same time, but it won't work.
When I plug my HD2 into the charger, the red light also doesn't come. It just stays dark.
If I try a hard-reset this message won't appear on my HD2:

It's possible that your battery has died. Do you know if it had any charge on it last time it worked?

I'm almost certain it did charge last time it worked.
Also, I was on vacation in a very hot place and my cellphone was in the car for some time. Is it possible that the high temperatures broke my battery?

oops... Sorry. May be the battery dead. Was it a original stock battery or some china made brand? If it is original one then you can go for warranty claim if your phone is under warranty. I don't think battery may dead so early but if it is not original (as some china made type) then we can expect that. Don't use those batteries as they hold the explosion risk too.
I use the original battery.

Does your Phone not respond in any way?
Have you tried this?:
Plug in Charger and then put the battery in, normally the phone turn on with this method.
Does that also not work?!
Take a Look if you charger and the cable is broken. Use another cable (if you have a Logitech Performance MX try the cable from this mouse).
Try to measure if the battery is dead. You can also use your tongue to test that.
ATTENTION: You should do that only on low voltage parts!!! Like batteries until 9V for e.g.. DO NOT LICK ON A ELECTRICAL OUTLET!!! You would be suprised, beleive me (no I don't try this )
Plug your USB Cable to a Computer if you are not sure if you charger works.
The HD2 vibrates -> TWO <- times before it starts.
One really light and short vibration and one you could not miss^^
Does you phone vibrate when you try to turn it on?
Okay, so I bought a new battery, but my HD2 still won't work.
It's absolutely the same problem.
wife had this problem too was solved when we noticed the pins inside the phone were bent for the battery. fixing them got rid of the problem.
no seems to have mentioned that yet so take a look, they wont be bent much but that is for us.

I think this could be the solution. I recall bending them a little now that you say it.
How exactly did you bend them right again?
Thanks.
I tried to bend them right again and when I tried to boot my phone again, it didn't work.
Same issue.

I'm like 90% sure my first battery was nearly fully charged and I assume the new one I bought usually should be fully charge too, right?
is the bottom of the back of the phone warm?
If it is then, i suspect that your motherboard is overheating.
Mine has frequent lock ups and sticking it in the fridge for 15mins (seriously) helps with the boot up.
Also install Battclock so you can see what the CPU % is, as mine would always lock up at 100%, perpetuating the overheating issue.
Let me know if the fridge helps your boot ups.
Mine will be going in for service soon, its only 6 months old.

OK,
Can you get into the tri colour screen?
i think at this point your goal is to get it working.
You may have to sacrifice your data on the hd2 though.
Pull out the SD card. then remove the battery.
Hold the vol button down and power on,
Try to get to the tri colour screen and tray to flash a new radio to it.
Failing that, perform a Task29, and try to boot.
10 mins in the fridge wont hurt it at all.
Try to boot.

It may be the battery. You can try to get a replacement on amazon for $9 or you could take the battery from your phone and put the 3 pin to your tip of your tong and see if it has any current. If it has current then ignore the steps below as it is your phone that has the problem If you have no warranty, or cash at the moment do the following.
DO IT AT YOUR OWN RISK! The only thing that can get damage is your battery.
Most likely your battery is dead, so plugging in a power supply to your phone won't do any good since the phone can't detect it if I'm right. But you try to can jump charge it giving it power to see if its the battery or your hd 2 that has the problem
If you are good with electronics and wires do the following in a safe environment. (Low Fire risk)
1.Take a spare wall adapter that came with a sell phone or mp3 player.
2.Look at the back make sure its rated no more than 5V
3.Cut the cable at the tip and expose the 2 wires inside they most likely will be red and black. RED = + Black = -
If both wires are black then look closely one of them should have a WHITE strip
The wire with the white stripe is the + and the other is the -
4.Make sure you cut the wire so the golden tips are exposed
make sure that they are neat and in place
5.Take the battery and notice on the back there are a + and a - take the wire and carefully match + with + and the - with - for 1min. It is very important that you do not make the wires touch because it will smoke
6.After 1 min remove the wires and put the battery in your HD 2. If it does not power on then your phone needs repair.
I wish you the best.

He did buy a new battery see http://forum.xda-developers.com/showpost.php?p=8847940&postcount=9
Are you saying that it wont turn on at all, nothing!
So you have tried holding the volume button up and down, and power on!
Original Post:
Hey guys,
After having no issue for the last month or so using CWM, tonight I booted into CWM as normal and then screen went blank.
I mean really blank, can't turn it off or on. Would a simple unplug of the battery and replug do the job or do I need to break out the JTAG setup? If JTAG is needed, does anyone know where that is on the board?
I did recently NVFlash from 1.1 to 1.2 so any advice on how to get this running again is invaluable as this tablet has info on it that I need to pull off. The only thing I can think of is if something in the recovery file got trashed and when it booted, it killed it.
Thanks in advance.
HOW TO:
Open up the Gtablet by removing the rubber pads on the back and unscrewing the screws seen. Then, using an iPod pry tool or flat screwdriver lift the casing snaps apart. Start at a corner and work your way through.

Locate the area in Red.
Now Unplug the battery, left speaker, and capacitive touch cables. Then go through and use a piece of copper braid on your finger or a grounding pad and ground out those connectors as well as surrounding capacitors (notice the two caps in the red box). *THIS IS A CRITICAL STEP*
Before putting the back on the tablet, throw the Tablet into AVX mode by pressing power and volume down. This will be the first test as to whether or not it worked.
Yays! We did it and did not have to break out the BusPirate to do JTAG!
Figured out how to fix it and it was fairly simple. NVFLASH is God!
Like they say in IT:
"Have you tried turning it off and on again?"
Two suggestions.
One. Describe that the 4 screws in the corners under the rubber pads need to be removed.
Two. Describe how to ground out the capacitors. One side or both sides? Ground out the connectors on the battery side or the tablet side? Which contacts?
ON XDA it is always expected for us Noobs to read and follow exactly what those in the know have taken the time to write.
Thanks,
Jason
I somehow ended up in a similiar scenario and used your instructions for getting back into APX mode. Problem is now that I have the stock ROM back installed and running I no longer have any response from the touch screen... any ideas on what may have happened.
Does anybody know which connectors/plugs are the touch screen, I want to make sure I didn't bump anything or knock anything loose.

Worked for Me!
Thanks for the instructions and video. Although I did not ground any capacitors, the battery reset did the trick to bring my tablet back to life. You are appreciated!
I updated the instructions, if anyone has this problem. Generally, unplugging + grounding + plugging it back in fixes most issues. Please send me a PM if you have a more serious problem and we can try to fix it, eh? (don't always re-check the thread...my bad)
Boot Issues
Ok, I can only boot my tablet via APX mode. I cannot enter CWM with power and volume +, the tablet does not respond to this, nor does it respond to just hitting the power button. Power and Volume - simultaneously does work so I know the power button works.
I was attempting to load CWM onto a stock 1.2 it didn't take or so I thought. So I attempted nvflash 1.2 boot with cwm and this is what I got. Did I lose a boot loader file somewhere?
I tried detox from gtabs for dummies. The only thing I haven't tried is completely draining the battery.
I am definitely perplexed. I have been flashing roms for about 6 months and have worked myself out of some soft bricks. This, I have not seen anyone talk about.
Thanks in advanced guys
Worked for me too!
I had the same problem of not being able to turn my g tablet on. I tried everything holding all buttons for various periods of time, connecting and disconnecting to power cord and usb cable to computer. No response. Panic was setting in. Then I came across this post.
I was thinking of calling ViewSonic to see if I could return it. Luckily I came across this post. Took off the back, unplugged and plugged in the battery (didn't do the grounding thing), and Voila! It was working again. This was such a simple solution that it didn't occur to me until my android phone did the exact same thing to me this morning. After freezes and other problems, I always just took my cover off and popped out the battery and pop it back in, and it works. Then I thought to myself, these tablets are nothing but big android phones. Let me try this solution.
Every question I've had, every problem I've come across, has been answered in these forums. I've never had to post a question because someone somewhere has already asked it and the answer was given.
Great job. Video was especially helpful. Thanks

Did you have reboot normally or with NVflash>?
While the back was open, I went into APX to confirm that it was working. Then, I just booted up normally. Now, I found my market is not working and I can't update or download something from the Market. I also noticed that I had a couple of Force Closes. So, I am not 100% clear of problems. I am in the process of researching how I can fix the Market and Force Close. I'm thinking of starting all over again from the start with NVflash and reinstall my Honeycomb Rom - GtabComb, including partitioning anew.
Ok great, so no nvflash necessary from APX?
G tablet stuck "booting recovery kernel image"
I have tried everything in this tread and nothing works. I still get "booting recovery kernel image" when I use Vol - and power I get the splash and then the screen goes black. No PC usb connection also. Do I need to let the battery go completely dead?

I am facing the exact same issue mentioned in the thread. Fortunately last time my issue was solved by opening and disconnecting the battery. But in two week it happened again. I know I have to open it again but my question is,
Do I need to nvflash and reinstall the rom?
if yes, what nvflash should I use?
my E18 tablet wont turn on
Ser i have mid tablet pc E18 .. it wont turn on.. anymore can you help me to fix it ..asap please
Ok I'm really bitter right now. My wife and I each have an S2. Mine has been fine for the last 2 months and hers recently starting having problems. It keeps thinking that a USB cable is plugged in.
A Google search reveals that this is indeed a common hardware problem.
When you do a restart, you get the battery icon and flashing yellow triangle with the thermometer symbol. And the only way to get it to boot up is to plug it in.
The device functions fine other than that, but other than connecting to Kies via USB, there is no other USB related functions that is working.
Gonna give Samsung support a call and see how I can warranty this. Hoping it's not going to be a painful process.
Anyone else having the same problem? How did you resolve it? New replacement? Did they repair? How long did it take? What did you do?
Thanks.
I have the same problem, started with me recently, I had my phone with USB debugging mode on.
Can't confirm when it started for sure, but it may have been because I disconnected it from my computer once, before ejecting the device through windows explorer.
In any case, I can't turn on the phone now without removing the battery or having it plugged in.
I received the battery at 100% notification and it doesn't leave when I unplug the device.
It's become very flaky, and I don't like it. Did you have any luck with Samsung support?
Anyone have any information on this or another link to how to fix this? I'm getting the temperature gauge and can't figure out how to fix it!!

Brother had the same problem. Try adjusting the piece in the USB port of the phone either up or down. I used a small flat head screwdriver. Make sure the phone is off and battery out.

Yeah - get a replacement.
I had similar issues with mine. Took it to Carphone warehouse in uk. And they replaced usb port within 30 mins. Its a common fault.
Try to clean USB port.
This morning I just noticed this problem with my phone and I also noticed that under the battery stats it shows that the phone is always charging.
If I reboot the phone sometimes I lose about 20% from the battery, but then it starts to recharge although the phone is not plugged in.
I will try to change the battery with a friend of mine, maybe it's battery related, I will report back.
I suppose that the problem of discharging is:
A) when connected it can't enter in deep sleep mode
B) vbus_present eating battery

Hi guys.
Just now I was trying to use my phone and suddenly it couldn't turn on anymore. I searched around in the internet and found out that it might be the problem of motherboard.
It doesn't turn on at all. So I am wondering if I change my motherboard, will the data inside be wiped too?
I am okay with the apps and stuff but I don't want to lose the pictures, contacts and my texts.
Any idea on what I can do ?
I really really really don't want to lose those 3 things mentioned.
Thank you a lot for any replies
What (if anything) did you do to resurrect your phone?
Did you remove the battery for some minutes?
Did you try turning it on with the help of a USB Jig?
Does the phone charge?

Hi guys.
Just now I was trying to use my phone and suddenly it couldn't turn on anymore. I searched around in the internet and found out that it might be the problem of motherboard.
It doesn't turn on at all. So I am wondering if I change my motherboard, will the data inside be wiped too?
I am okay with the apps and stuff but I don't want to lose the pictures, contacts and my texts.
Any idea on what I can do ?
I really really really don't want to lose those 3 things mentioned.
Thank you a lot for any replies

As far as I know the memory is part of the MBO so if it gets replaced the memory gets replaced too, hence all data not on external SD will be lost.

What (if anything) did you do to resurrect your phone?
Did you remove the battery for some minutes?

I did remove the battery for about an hour. Charged with and without battery on. No response both ways. I don't own an USB Jig so I didn't try that method. I am using official ROM, most probably 4.0.4 ICS. Any clues ?

What I was trying to say is: does the battery get charged, i.e. if you connect the AC adapter to your phone (which is turned off and has the battery inserted) do hear a sound and do you see the battery charging symbol? If not, how can you tell that the battery is charged at all? First of all you should make absolutely sure your battery is fully charged, for instance by putting it in an other phone.
Once you know the battery is fully charged the Jig might help. You should also try getting into download mode by using Volume Down + Home + Power button. But again: first make sure the battery is charged.

I used two different charger and tried to charge the phone and nothing came out on the screen. No battery charging symbol. It remains the same dark screen. I will try to find another phone or battery that can fit to test, most probably at the stores tomorrow. But I am pretty sure my battery have some batteries left. If so, anything I can do right now ? It doesn't switch on at all so I guess that's why the download mode didn't work ? Is there a big possibility of it being the motherboard ? I don't mind replacing anything but I just don't want to lose those important data. Thanks for the help
Can you get into download mode? Use the volume down + home + power button combination.

This could be a problem with the charging port connector print ...

Without Jig? No. Probably order one from Ebay? The Jig is quite cheap so you do not loose much money if it does not work.

I don't know, sorry. See my first post concerning MBO replacement.
Thanks a lot. I will see what I can do at the stores later Hope it's not the motherboard problem. If not I guess I have to lose all the data.
Ohh

Hey guys, last night something happened to my good old S2, i had problems about it's battery before so when it's battery suddenly dropped down from %20 to %0, i wasn't surprised. So i went and put it to charge (i don't use the original charger, i found a huawei charger and it gets the job done) and after a moment it showed that it is at %50 battery (like i said my battery has some problems), so i tried to turn on my phone. Then it went in a boot loop on the Samsung logo, i was going to turn off the phone so i can clear the cache partition so i unplugged the charger cable and it suddenly went dark, no power, no nothing. I tried to put it on charger again but it didn't help. I let it charge there overnight but it didn't help either. Then i borrowed my friend's S2 battery and it didn't work while my battery powered up his phone so i think problem is not on the battery. What do you think, is my phone bricked/fried? I had a photo archive in my usb storage(not in the SD storage) so i really wantt to recover it if its possible in anyway. Your help will be greatly appreciated. Thanks..
Thats wierd , try with another charger and the original battery and let us know how it went.
PS:That phone is a though piece of hardware mine is still runing (of course after a lot of repairings and software changes) after 5 years , finally swtiched for lg g3 used from ebay , best deal ever

I tried another charger adapter (not original, my original charger is not working properly) with different cables and it didn't work. And for the battery, i have an original battery and it didn't work, then i used my friend's non-original battery and it didn't work either like i said before. But my messed up battery turned on his S2. So the problem is probably not on the battery.

No, pc doesn't indicate anything that my phone is connected nor the phone shows "charging" indicator.

Hi there. I has a similar problem, the phone was working but even with the orginal charger plugged in was not charging at all (connection to PC didn't help either).
There is a procedure to "retrigger" a stuck charger IC.. I lost a link to it and I'm looking.
Had something to do like:
_ remove battery
_ plug phone to charger
_ insert battery
_ turn on
After that I'm not sure anymore.. maybe again "remove battery" step. After that put everything to rest, insert battery and then the charger and see if it works.
I'm googling, someone made a post on XDA with the full instructions.

Ok thanks please let me know if you find the full procedure and I'll try it
Hi, I found the procedue, it's exacly how I described the 4 steps above (the source it's on a external forum, I'm not sure if I can link it here - I'll send you a PM if you like).
SO, if the phone was stuck just like mine, working until the battery discharged even if plugged-in, that will solve it quickly (mine did precisely).
Otherwise.. there could be several reasons why the phone is not recognized anymore, some point out a faulty cap around the charging IC (if the phone is totally dead):

This cap, if faulty, is actively shorting "Vbat - Gnd" line thus prventing any operation of the phone. Could be water damage o defective charger. It depends how much you want to dig to repair your phone (there could be 1000s other reasons - this is the most HW one).
From what you described the problem in your post.. this defective Cap would/could explain many things.
How are your soldering skills? First thing I'll do is to open the phone and inspect, possibily with the help of a multimeter, next desolder the cap and power the phone back with a charged battery (don't connect the external charger, there might be burned pcb traces - but that's anohter story).

Sadly the first procedure didn't work. My soldering skills are not that good but i might know someone who can open up the phone and do things properly Do you know any detailed instructions for the second method you mentioned? Thanks..
I've no other details other that the picture. Before tearing the phone apart, you should try to test "continuity" beteween the "+" and "-" metal contacts of the battery holder. If you have a friends with a multimeter he will know how/what to look for (tell him about the short).
