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.

Call HTC support. Do you have their #?

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.
Can anyone please help me?
is the battery that you got now at least 50% charged? if not try to find anyone

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.

Thanks for the suggestion, but it did not help.
I left it in the fridge for 15 mins and started to boot it but it just didn't react.
I haven't been able to boot my HD2 for a few days now.

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!
I have read tons of threads on this and none of the answers are working for me. I was running Nero v3 and flashed a newer voodoo kernal. It booted back into CWR. I guess I hit the wrong option and now the phone will turn on to the Vibrant/Samsung screen and nothing else. No download mode and now recovery of any kind. It has been on the Vibrant screen for 45 min and no matter what I attempt, it will not do anything else. I would be willing to tip someone that can get me fixed.

I remove the batter, sim and sd.
Hold vol up and dwn.
put battery in.
I have the same Nero rom you do and ran in to the same problem. This is what worked for me. You're going to need a computer, usb cable, your phone and battery.
1. Take the battery out of your phone and make sure it is off
2. Plug the phone into the computer with the USB cable *Without the battery in*
3. Put the battery back in the phone
4. Wait for the charging screen to come up ( the screen with the green battery)
5. Press the power button to let the phone boot up
After these steps the phone should boot up normally and you should be able to go to either your back-up rom or install another in rom manager.
Like I said this worked for me and I hope it works for you as well.

Anyway if that doesnt work just power off the phone plug the usb into the computer only then with the phone off hold both volume buttons then plug the micro usb into the phone that will get you into DL mode .

That didnt work out. Im still at the battery screen.
You almost have the right combo for dl mode. Assuming you have your drivers loaded, lets begin. First things first have odin open on your pc, your pit and tar files loaded, ready to flash your rom. Take out battery, sim, and sd card. Phone off, plug the usb to pc, hold down both volume buttons then pop the battery in. It must be a pc, a wall outlet sends a different charge and wont trigger dl mode. You will see a com port light up in odin, hit start and sit back, it should only take a few to flash. If it hangs for more than 5 minutes at any one particular part of the flash, close and relaunch odin and repeat, boot to dl mode etc. Oh and if you dont get dl mode the first time, try it again, sometimes it takes a few goes to get into dl mode.

WEll..... this did not work after several attempts. I can not get into dl mode or recovery or anything. I downloaded and installed Droid Explorer and it sees the phone but there are no folders and none of the plugins will work for reboot to recovery, flash recovery etc. Do I need a stand alone recovery file for Droid Explorer to work?
Keep trying. Take the battery out, let it sit for a few minutes, and try again. Still not working? Try, instead of holding down both volume up and down, try the same method, all cards and battery out, usb cable into pc and phone, hold down the volume down only, then pop the battery back in. I know it can be frustrating, one time it took me 45 minutes to successfully boot to dl mode trying over and over.
Just know, if you're seeing anything at all on the screen, you are not bricked, and it is possible to recover. The volume down only method worked for me the first time I had the same screen you are seeing. If you're getting frustrated, walk away for a few, go get some fresh air or do something to take your mind off it and come back to it when you're fresh.
Try both ways, with both volume buttons or just the volume down. Being sure to remove the battery after unsuccessful attempts. Diligence will prevail, don't get frustrated easily, and keep trying.
Also, once you get successfully flashed and back up and running, flash this recovery fix. After flashing this, I can get to recovery and dl mode so easily its stupid. Of course all the steps I am telling you are what I had to do before I flashed the fix linked below.

Thanks Br1cK'd for the info. I have tried it both ways and everytime I put the battery in with the usb cable in, the phone will not go past the gray battery image with a frozen loading icon in the middle. But I continue to try.

3) hold down the two volume buttons but not the power button
4) plug USB into the computer
5) plug usb into the phone

Just to be clear, plug the usb cable in, hold both volume buttons while popping the battery in. From what you are describing, it sounds as if you are releasing the volume buttons when you pop the battery in. Even if you release one or the other and try to press again, it will not work, and you have to unplug the usb and start the process again. Can be a pain in the ass, I know. You must hold them down and keep them held down while trying to boot to dl mode. Man, if you are anywhere near colorado springs, I'll do it for ya and flash that fix for this I posted earlier. Just be sure you do not release the volume buttons when popping in the battery.
What works for me, is to hold the phone face down in my palm, with the usb cable plugged in. Find the right angle to hold it and keep the volume buttons depressed, and in goes the battery. Again, good luck friend.

That's exactly what I have been doing. If the fingers slip off, I start over. It is the oddest thing. I have experienced troubles before with other phones, but none this difficult. Im not real close to CO or I would take you up on it. I'm in TX. It doesn't matter how long I hold the vol button after the batt is put in, it only shows the gray batt and non-animated loading icon.
Someone mentioned the hardkey lock. I have never heard of this...

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

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?
Mark
smooth bean 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
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 ..
This may or may not work for most but this worked heavily for my 2 units that had the same issue. One with a broken nvflash, the other that faced a bootloop and never booted up again. Took almost a week and I felt almost all hope was gone because the bloody service centre's refused to accept the unit's as they were not purchased from the region, rather online. Scumbag Samsung .
[!] This is usually a 90% fix for both broken nvflashes/deep sleep of death, considering you haven't drowned your Tab by now with no hope . I ask that you kindly attempt this once if you haven't before you QQ to the nearest Samsung center like I did.
- Drain your tablet
And by all mean's do so, The quickest way to get this done in less than 2 days or so (Depending on the battery percent charged) is to get a clear tape and tape around the power button pressed.
- Testing if you have drained it completely/Taped it right.
Connect the tablet via USB to your PC, make sure you have the NV Driver files [http://forum.xda-developers.com/showthread.php?t=1130574]
Just install the driver and proceed to the step where it asks about holding down the [Power button] +[ Volume+] and wait for the constant USB connect/disconnect sounds. It also helps to look at Device Manager to see if it still pops up.
When the battery is completely drained it will stop popping up in the device manager, and your ready to go.
MOST IMPORTANT STEP
You have only 1 and only 1 chance per drain to get this done right. Plug it into the socket charger and see if the charging icon should come up, after being fully drained you should see the charge icon should pop up [100% tested and works, this step is annoying but it's the tablet version of taking out the battery and popping it back in] and what ever you do, DON'T BOOT IT UP NORMALLY, instead press [Power Button] + [Volume -] keys and let go when you see the logo to get into fastboot mode.
Select the android buddy with the [Volume +] key and it will boot into Download Mode.
From here on out everything is easy sailing. Get the right firmware and Odin and flash the firmware you require. It doesn't matter what region you are from, the tablet is made to accept any regional firmware BUT the model number should be the same. Which mean's 7500 for 7500 ONLY.
Edit: Since you have only one chance per drain, I suggest you flash a stock firmware rather than flashing CWM to save it, Because CWM would only fix the recovery, It wouldn't fix the damaged bln. The fastest way to get a stock firmware is grabbing the stock firmware from the Overcome thread
Will taking the battery out work ? or do i have to drain the battery then turn it on ?
and for the duct tape, only power button ? because my computer won't recognise my tablet unless i use the APX mode which is (Power + Volume up), in that case i guess i have to table both power and vol down ??
There's no way to remove the battery since it's like hardbound inside. Drain it to turn it on sir.
Yeah you should get it plugged via APX mode. Press it for 15 secs both then connect it via USB, After that you can hold it down via tape, the power button only.
Maraming salamat po!!!!!!!!!!!!!!!!
(Thank you very much)
I have tried so many ways....but this may actually works..
So did you get it working? If it did I'm glad for you
tried it for the first time, didn't work and i'm giving it another try. I taped the power button to drain the battery completely, i'm gonna leave it for another day. Then tape both (power and vol +) and plug into the computer until it stops popping up ? then plug it into the socket to see if the charging icon show up ?
am i doing it right ?
my tablet is a galaxy 10.1V
Nono, Just the power button to clear the power cycle, No need to tape the volume button, Once it's in the APX mode, you just need to hold down power button and it will keep looping. when it stops appearing in device manager, It's completely drained. Actually, once it's completely drained, you need to plug it via socket charger to see if the charge icon shows up :] Then you're ready for Odin :]
Thanks so much for the helpful post, and detailed instructions.
I've drained my battery, 100% - confirmed by connecting to PC, not detected. Plugged it into wall charger, got the 'battery charging' indicator.
From there, I boot into Download mode, and fire up Odin. The device is detected on an appropriate COM port, and I can push a CWM or stock recovery image, and get a big green PASS. (usually - I've performed these steps several times, and occasionally it Odin will hang)
And yet - the device will never boot to completion, nor can I get into recovery mode.
I'm confident an underlying problem is that the device was (IS) encrypted - which is confirmed when rebooting normally: I get the pre-boot authentication page prompting for (and confirming) the passphrase - and then the android / gear outline, then... black screen. Nothing.
When attempting to select recovery mode - same thing: screen goes black, and nothing (same results whether stock or CWM recovery flashed).
Thanks again for the information - I'll keep reading, and testing - and appreciate any insight anyone may have.

Actually this is what I mentioned earlier, The problem is you have one chance per drain and you used that to flash CWM If I were you, I would suggest flashing a firmware, Probably 3.2 HC EU/US firmware of your choice. Then when you get it to boot (You should feel that slight vibration when you boot it up) after it works, you need to shut it down properly and flash the CWM.
I made the same mistake Cost me again another 8 hrs, Just for 5mins charging. FML.
However i have updated the OP with a slight "Edit" note
On another note, Updated the OP
i have tried 3 times already, didn't work ... what kind of tablet you tested the on ? mine in galaxy 10.1v.
what i did is .. i taped the power button for about 2 days, then when i plug it into the computer i can see it popping repeatedly and it won't stop because as far as i know its actually charging from my computer ..
i have actullly disassembled it and took the battery out .. but i just turned it on normally and same thing (black screen) , according to you i should not turn it on just like that .. however i should power it into recovery mod.
my question are: is taking the battery out as same as draining the battery ?
because i still couldn't figure out how to drain the battery and test that at the same time
thanks in advance, and i'm just trying to give it coupe of tries before i lose hope

Actually yes taking the battery out is the same as draining it because in truth the tablet isn't like a phone where you can pop out the battery, You can however remove it since you have disassembled it already. Instead of draining it, Try Power and Vol Down directly after popping the battery back in. Once you get into fastboot mode you need to flash the firmware via Odin. I wouldn't lose hope if I were you :] I had the same issue, Then I fixed mine.
Yeah one was the 10.1v and the 10.1 both were fixed the same method.
This however shall give you hope :] Once bricked for a week, Now alive.

my Galaxy Tab 10.1 was bricked second time in one month, this really is a annoying issue, unfortunately samsung doesn't provide warranty in my country, not uptill now. First time I had to give it to the market for repair, the person charged me around $50 for the repair and did that in one week. The symptom were the same, I turned it off and it never came back online.
Second time, i had no choice but to dive into the issue and solve it myself, as it was totally insane to pay this much for every time my tab throws tantrum at me.
This time I discharged it fully, as you told, and tried to check it by plugging it into the system, but every time it appeared as APX device, so out of frustration I just plugged it in to the socket, and voila the battery icon appeard, i let it charge for sometime, pull out the charger and boot it normally by pressing the power button, and guess what it was back online, with all the data and everything. I had a hunch that it would turn on as, the first time, when sent to market, sharing my lattitude with my dad i was appearing at the shop location, meaning it worked there, that stupid opportunist simply wiped it and charged me $50. But now i know how to save that money
PS: I was able to identify the cause of the issue, atleast what happened with me was that i powered off the tab while plugged into socket both of the time, it never came back. Something you might avoid for this problem to occur.

For some odd reason it happens different for most tabs, I don't know if this is Samsung's first dedicated tablet apart from the 7" that was a huge wafer or a loaf of bread But as far as I know that was just an oversized phone without much tablet dedication compared to this. In my case dad had turned off the tablet while it was on a bootloop and it never turned on again, that is until I tried out the above method and it worked, So far so good I'm on the CM9 Kang and no issues so far. Thank tablet God.
i've used a terminal app to force my 10.1 p7510 to charge when plugged in into the usb.. now i'm also thinking that it might be charging even while it's on DSOD or bricked.. : /
i guess to avoid getting bricked is to never turn it off.. sigh.. just keep on killing apps, clearing memory, etc..
i'm still hoping and waiting for it to be drained.. tried plugging it in for about 3 seconds to check if the battery icon would pop-up nothing.. so back to plugging it into my pc and taping the power button in..
Quick Update:
the tape keeps on loosening (don't want to stick it too much over the screen since it might pull off the matte screen protector) so i took 2 rubber bands and affixed it to my tablet.. made sure it was tight enough to pull down/in the power button ^^

I just happened to use one of those 3M Scotch tape I had lying around in the house, was pretty good and didn't leave any tape marks on the device. Yeah offline charging apparently is a bad thing for the tablet which is why I never chose to keep/enable it despite it was already there via Overcome ROM. Easiest way to drain it is by holding the power button down, best be unplugged and leave it to drain that's the only way you'll know it doesn't get charged, should take a max about a day or more depending on the % of charge it has.
One thing I found out was, You can never really brick the tablet completely, Unless ofcourse you flashed some other device's firmware on it. I do hope the ICS official release has some sort of fix to this, rather than the boring immense hours you would have to wait or pay just to get it fixed.
I do however wonder how many have gotten their tablets fixed via this method..
well you know what? i've just arrived from work and i turn on the speaker of my pc and it's still doing the badump-badump sound.. so now i'm guessing it's looping the on and off thing as well as the usb charging feature.. so now i'm gonna leave it again for day UNPLUGGED from my pc and hopefully tomorrow night it'll be all ready for reflashing.. sigh..

Yeah don't worry so much about it, You'll know if you did it right when you plug it into the socket and you see the battery charge icon, That's a sign that's it's completely drained and recharging from scratch Remember to flash a stock firmware first as that fixes the broken bootloader. Recovery module won't do much.
Do keep me updated

A fully charged one takes about a week to drain, according to one of the member
