This started earlier in the week. I think I loaded the Free Monopoly, Contract killer and Text Plus in the morning when it started. I'm thinking this was Tuesday or Wednesday morning after Christmas.
At the Time I immediately killed and uninstalled all three of the recent app additions. This did not appear to resolve the issue.
Symptoms
Screen would not remain off for more than a few minutes without turning itself back on again. Full screen wakes.
Occasionally and without warning the phone would completely turn itself off, requiring the very long power button press to turn on again (was a full power-down).
Since this has started I decided to upgrade to the latest unamed rom.
This does not appear to have helped anything, although the frequency may have been reduced. I don't think this is related to the ROM since the issue survived the factory reset / wipe / rom change.
Questions
Are there any internal logs that may help to point me in the right direction?
If so, where / how can I view them?
I'm seeing a RILJ dialer something under Partial wakelocks in BBS.
I see this as [p]_RILJ under Kernal wakelocks as well. Any Idea what this is?
I admit, I was getting a bit silly with the quantity of Apps I had loaded and still running well at the time. Amazed the phone was still going very strong with no issues at all. I'm trimming this back on the new rom.
Any help would be greatly appreciated.
Random Illumination Wakes and sleep crashes.
Still trying to nail this down.
Additional observations.
Timing appears to be random.
When I say the screen wakes up, I'm mean illuminating.
The wakes appear almost as often as the power off freeze. What I mean is the quantity of complete power off's is similar to the screen wakes.
It's very possible that the same event may be causing both the screen wake and the hard starts. Neither issue occured prior to this the starting of both events.
I have occasionally seen the "Driving Mode" steering wheel icon pop-up, while unplugged. I've not connected this phone to any kind driving interface as of yet, so this is a surpriseds.
Today I had additional issues with extremely heavy battery drain in a short period of time. I had incorrectly added 2650mA under battery capacity beneath Calibration tab of "Battery Monitor Widget Pro".
Still looking for help finding and viewing any error logs on the device.
Does anyone know of some basic error log files on the device?
Again, all help is greatly appreciated.
Under Recent unamed ROM but I do not believe the ROM is the issue.

These random screen wakes, particularly with the car mode activations, are what I was seeing when my usb port on the device failed. there are several threads in the general and QA forums regarding usb failures, you might want to dig around in there to see if other behavior is similar. I think one poster mentioned cleaning out the USB port with alcohol and a small paint brush. I had tried doing the same with canned air, but that did not help me. I ended up with a warranty replacement device.

I think you may be onto something.
Since the event I am also having issues connecting up to my Win7 Pc.
On the morning of the event, I remember a brief weirdness to the charging indication. I think it said it was charging when it wasn't or vice versa.
So now the question becomes.
What do I need to do before an exchange?
Purchased from Best Buy on US Launch day without extended warranty.
Do I still have a warranty?
Can I go to the AT&T store in Sacramento?

Your phone has a 1 year hardware warranty. Talk to Best Buy, and force them to give you a replacement. I did that with AT&T, not putting it on the phone insurance, but the phone's warranty that came with it, for free.
Backup your apps using a tool like ROM Toolbox from the market (it's my favorite). When you restore your phone, all apps that AREN'T sideloaded will come back with the last Google Sync you made, so sync now. If you're sure, 100% that it's hardware and not software, make a backup via CWM and ignore all previous instructions, but if you're like me, you'll want a fresh restart with the ability to axe all the apps you don't use on a clean ROM.
When backing up all non-sideloaded apps, Google does it for you, use a backup program from the market to ONLY backup your sideloaded apps.
HUGE ADDENDUM:
READ THIS. Alright, before taking it back to Best Buy, flash Entropy's "Back To Stock" ROM and kernel. If you don't, you're done. Warranty voided. If they are intelligent and check the flashcounter, and see you tripped it, but you're on a stock ROM, you can talk your way outta it. Try thinking of something before you go in. The excuse I will use if ever needed is I was clueless about why my phone was ****ing up, so my friend who said he could fix it took my phone for a day and temporarily fixed it, and it worked alright for a couple days before the issue came back. So you can claim ignorance IF NEEDED, but most of the time they don't check. Just be sure to have an answer for if they do.

I do have a jig and I do not have the Exclamation Icon.
However my boot animation is no longer stock and I have not been able to read the flash counter. The Power-off, Hold volumes and plug USB thing is not working for me.
To date, I have not caught anything in software to cause this.
Getting myself ready, Thanks a million.

As long as you used a root method that should not have increased the counter, I think you can mobile Odin back to stock unrooted to prep for warranty return.

Shot back to this ROM
Kernel + cache + rooted UCKK6 system package: http://www.multiupload.com/NYL3XT51Y0
Feels like olden times.....Naked in front of the Gym class.
Beyond Best Buys 30 Days so had to go to the AT&T Service center.
They grilled me, checked, wiped, reflashed, yada-yada-yada.
Gave me the could be an app shpeel, did you use a car charger questions etc.
Long story short....
They want to try a new battery 1st.
So, news years eve overnight, maybe by Monday.
I admit this could be a possibility because I have had the battery lose a large amount of capacity in a short amount of time one the order of Full to Dead in 2-3 hours. This has occurred to me on maybe three or four occasions since launch day. Phone got warm to hot at the same time. This usually included a hard kill power off. Nice big gap / drop in battery stats.
Is there any way the phone would get a charging indication yet not charge?
Like if the USB port got wonked or crossed with something?
Additional Weirdness:
I have had the phone freeze up on me, picture turn weird as it gradually whitened to full white screen only.
No response from the keys or screen with the exception of a long power button press to recover. This occurred a few times since the original event (maybe 3) with the last one happening while plugging it back in for some juice for the return today.
Keeping this up to date in case others run across the same funkyness.

I got the "try a different battery" story too. Conveniently my wife also has the I777 as well, so tried hers. No joy for me. After that, rma was approved. Good luck!

It ain't the battery man. The symptoms you described fit perfectly with a fried micro usb port.
If you haven't set the flashcounter off, and your phone has the AT&T boot logo, then you're good to go as far as exchanging it goes. DO IT UNDER WARRANTY AND NOT INSURANCE. This is the **** quality of the usb connecter, not user caused.

I doubt it too, since the original event involved the AM unplugging from the charger. I always check the Next Amazon app, 1st thing.
I can honestly say that:
The phone has absolutely never been dropped.
The USB cable nor port has never been stressed, tweaked nor twisted.
Never used the phone with the cable attached.
Neither the phone nor the Taurus gunmetal case have a single scratch.
The phone has never been close to water, save for the obligatory post shower, AM, moist towel screen wipe (ok.... too much info).
I think I had 137 apps on this thing until the 1st event last week. In those original two months I've had maybe 5 force closes or other events. The force is definitely strong in this one!
I hope they forget the "new" battery when the time comes for the full swap?
As always, thanks for everyones help. I'll post this through beyond conclusion for the rest of us.
Definitely the USB port is screwed. I'm on my third phone cuz of this issue. First guy at best buy said it was probably because I wasn't using stock launcher. Whatever. Second replacement was easier, just a young girl who never even looked at my phone, and just gave me a new one. I did go to a different best buy second time to avoid possibly getting another phone from a bad batch. I've posted on other threads on this issue about the fact that this problem might be caused by the lack of a cover over the USB port. Maybe i'm wrong, but it seems to easy for junk to get in there. If you can't flash back to stock via computer, you can try mobile Odin, however I ended up soft bricking my phone trying to run the stock Odin one click via drop box through mobile Odin. Don't know if file didn't completely DL through drop box, but I couldn't fix soft brick since I couldn't connect phone to comp using the USB port. Long story short, my advice, flash stock while you still can, and keep it that way cuz the problem most likely won't go away.
Sent from my SAMSUNG-SGH-I777 using XDA App
Additional info:
I performed a factory data reset (from the settings screen) prior to re-loading the unbrick/return to stock ROM. Also wiped all three memory areas prior to the rom.
Last night the Driving mode Icon and V-Lingo kept popping back up as if I were connected to a car adapter. I have no use for either as I have no car adapter yet (was at home). No cable was attached at the time and the phone was sleeping. This occurred a half dozen times or so.
I also randomly receive the USB connected icon despite having nothing connected to the phone. Says MTP-Initialization.
Odin 3 worked yesterday without any issue. Droid explorer also appears to work but Kies has refused to connect since the event, even with the New years update. The Win7 pc randomly recognizes the phone. Sometimes it's ok, but mostly it does not show up at all with the pc saying "USB device not recognized...".
With USB Debugging turned on, Kies says:
"Reconnect the device in Samsung Kies (PC Studio) mode.Current mode not supported by Kies."
I switched USB debugging off 1st thing this morning and it looks like Kies USB is working ok now.
Kies Air works like a champ.
Still think the USB Port is dorked. Probably the USB controller chip as I don't think I have any physical looseness. I really wish USB connectors were longer and deeper with screwed attachments to the motherboard in addition to the soldering.
Correct me if I am wrong here, but I thought that the "Driving / V-Lingo Mode" is Hardware triggered and it is not possible to trigger this mode with any software. At least that is the impression I got by reading the car cable connection cable discussions.
More fuel for the bad USB port fire?
Since the multiple wipes and return to stock, I do not think I've had an event from sleeping to hard crash / reboot required.
Still having wake-ups and spurious driving mode activation's both plugged in and unplugged. This may or may not be accompanied by the V-Lingo, terms prompt.
Prior to going back when the replacement battery fails to improve things....
Can I kill / Delete everything on the phones internal SD memory?
Not thinking,.. I still had the Titanium Backup directory along with Clockwork Mod etc. still on the phone when I brought the phone to the service center. Had they checked the phone directory, I could have lost warranty, etc.
Any other directories I should look for?
Just Realized I had not stated my Hardware Level.
Model: SAMSUNG-SGH-I777
Android Version: 2.3.6
Baseband Version: I777UCKK6
Kernel: 2.6.35.7
Build No. GINGERBREAD.UCKK6
Still getting spurious wakes with the USB port thinking:
It's connected to a PC.
It's connected to the car
or V-Lingo launches thinking I'm about to take a trip.
All of these occur with nothing connected at all, and typically the phone is sleeping. Still have not had a repeat Hard crash since the wipes and return to stock.
Do we have enough of a known hardware history here to know / avoid certain builds?
No. Not much effort has been put into figuring the faulty USB port out. Entropy and I even hashed it out in Q&A, both of us thinking it might have been the software. Truth is, you'll probably find more info in the international SGS II community than here, as more were sold, and our SGH I777 was discontinued only a month or two after being brought to the market.
Because it hasn't been reported on much, no one has thought to start observing the hardware for faults. You should consider doing so - I can tell you some information on my phone model later, after I remove the battery and such. Maybe shoot GTX or Entropy a PM to ask them for tips on identifying different hardware models and state why you're interested. As I said, I'll post my info on my new replacement, and observe it to see if the same problem occurs as it did in the last one.

Unfortunately I don't know if I can track down the info on my defective phone now, since it has been gone for several weeks.
Also: I was under the impression that the i777 had in fact NOT been discontinued, only not stocked in COR stores in LTE markets. I'd be interested in documentation on the discontinuation if you can provide it...

Wow, your thread has quite a few similarities.
With the exception of the ROM selections, the device responses appear to mimic my own dead on. I was on "update-unnamed-v1.0.4-full" when the issue reared its head. Jumped to v2.0.1 to see if it helped, but again, I seriously doubt this issue is ROM related.
I'm still waiting for the "overnight-ed" battery.
I expect it will arrive tomorrow. With any luck I can grab it from home at lunch and charge it at the office. Put an effort into trying it at least.
That pushes my eventual return out till Wednesday evening / Thursday morning. I'll be sure to get the serial number data from it before it goes back.
Would it be insecure of me to post the old serial number data after the exchange?
I'm wondering if charging device, cable or PC could have had something to do with the failure. Pretty sure the cable was stock, but the plug may have been a logitech. This arrangement had been used nightly since launch date, so I doubt it.
Electronic chips can do some funny things. I'm fairly certain the port itself is still firmly attached.
As always, thanks for everybody's help.
Hi,
I would like to disassemble the Nook and use it without the battery. I have seen some tear down tutorials and does not seem very complicated but before I could start I would like to know if anyone hastried it.
Of course the Nook would have to have a power source (well duh :cyclops but I was thinking that the power would be provided by the charger. (Power on with charger connected / power off once done)
What you guys think?
It's very possible since the Nook can be used while charging. I have several "battery powered“ devices that will now only work off the charger because they are so old, the battle is completely dead.

HI All,
I wasn't even sure I was going to post this or not but I thought it might help someone out. This is not meant to be a "how to" post and you should proceed at your own risk.
A friend of mine had a 16gb Touchpad that he hadn't used in several years. It was just sitting in a box for several years. When I told him I was still using mine to watch videos and such he decided to dig his out. Unfortunately it wasn't in very good shape. The battery had swollen and had practically pop the screen out of the case. I'm fairly handy at fixing things so I told him I would give it a shot to replace the battery.
I wasn't very hard to open the case because the swollen battery had pushed the screen up and gave me easy access to the clips that hold the screen in. By gently prying up under the screen to released the remaining clips the screen came away from the other half. There are 2 cables attaching the screen to the MB so be careful. I wish I would have taken more pics but I didn't think about posting a how to. There are a couple of good how to's online and batteries are available online for around $30.
https://www.ifixit.com/Guide/HP+TouchPad+Battery+Replacement/6082
https://www.youtube.com/watch?v=zD2zGOsh6I8
Once I separated the screen from the body I had to pry the battery out. It is stuck down with some pretty sticky tape on the underside of the battery. You have to pry up pretty hard but you also have to be gentle as not to damage the copper foil that is under the battery. Once the battery is free you can give it a little pull to disconnect the cable from the motherboard. The online how to has you disconnecting all the little cables from the MB and actually removing the whole MB from the case. This is not necessary. The only thing that needs to be removed is the usb module and one or two screws from the MB near the battery connector. With a little patients, good light you should be able to mate the new battery plug to the connector. Just make sure you line the two connectors up and use a small tool to push the plug all the way onto the connector. Now once the battery is installed just replaced the parts in reverse order and you should be good to go.
Hope this helps someone,
Cheers
Thanks! My battery is equally swollen but working just fine, so I'm not sure if I need to do this before it fails. I hope it doesn't explode further or cause a fire!
It's curious, I was going to open a new thread right about that and I've found yours!
I extracted the old swallen battery from my touchpad many months ago but I still have to buy a new battery.
I believe that the batteries sold online were producted many years ago and, considering the value of the touchpad on the used market, 30 dollars are not little in my opinion.
Does anybody by chance know of any cheaper alternative battery that could be adapted to the touchpad?

They are lithium. If the pack is swollen it has gone bad.
Replace as soon as possible. The risks with lithium are too high.
Hi all,
It's over 4 years since the last posting in this thread, but thought I'd check in anyway.
The battery in my Touchpad does not appear to be swollen (no obvious bulging in the case. However, it seems the battery is not retaining a charge as long as it used to so I'm wondering if anyone has a legit source for a replacement. My backup plan is to take the TP apart and see if I can provide an access point for an external source (battery or P/S) and would be interested f anyone has done this, as well.
The TP is certainly not as fast or have as much memory capacity as current tablets, but its display is beautiful and the price was certainly right (firesale
Thanks in advance for any help.....cheers (and happy upcoming holidays!

Appreciate the links. They were helpful. However, it did not answer my specific question: Replacement battery and a reliable source for it. I will try some of the suggestions to see if I can "rebuild" the battery charging capacity, but at 11 years old, there will be limits to doing this.

Hello all
I'm thinking on developing an external power source based on lithium cells for my unit. The idea is to avoid the boot delay when the car is not used for some hours. The external power source will power the unit only when the car is not active.
- Does anybody knows what is the average consumption of a MTCD unit with no-music / no-screen active?
- Is there a way to power only the Android Module? Or a way to send a HW signal for he unit to go to "sleep" (but NOT turn off)
Thanks !!!
I also want to do this.
I have some spare cells that can use.
I think it should use less than 500 mAh with the screen off

Not necessary, with appropriate MTCD MCU and ROM version these units indefinitely sleep, consuming only 5mA, and immediately resume when powered on.
Suggest a search of the forums for all the info you might need.

+1 to that, i run a mtcd unit and a dual dash cam system (auto off at 12v) and they run fine over night without issue, when dash-cam shuts down stereo will easily not drain battery even after few days.
My Xtrons branded model came with a loop of wire with a quick disconnect on the main power loom. If I connect them, the unit will remain powered on after the keys are removed from the ignition. If disconnected, the unit will power down after a few seconds. (Still can't work out how to change this length of time though). What I'm thinking of doing is installing an inline switch so I can power the unit down fully if required when I know the car isn't going to be used for a while.
So, if the consumption is so low, in "normal suspended conditions", then the answer to the problem would be to keep the unit powered by the battery, but also keep on sensing the current to make sure it is really suspended and not consuming too much. My concern is that I do like to test new apps and ROMs in beta stage quite frequently, and I don't want to have any nasty surprise one morning because one app/ROM had a bug and kept draining the battery.
Another point to add is a timer, so after N days without starting the engine the unit is killed to protect the battery.
Anybody knows an easy way to get the unit to suspend when the power to the yellow cable gets off, but to not switch off? In the Androit 8 ROMs I use (Malaysk) the maximum timeout allowed before switching-off is 1 hour. Any easy way to modify this? (I'll do some research on my side also).
I'll post the circuit here as soon as I have some time to implement it

My concern is that I do like to test new apps and ROMs in beta stage quite frequently, and I don't want to have any nasty surprise one morning because one app/ROM had a bug and kept draining the battery.
Another point to add is a timer, so after N days without starting the engine the unit is killed to protect the battery.
Anybody knows an easy way to get the unit to suspend when the power to the yellow cable gets off, but to not switch off? In the Androit 8 ROMs I use (Malaysk) the maximum timeout allowed before switching-off is 1 hour. Any easy way to modify this? (I'll do some research on my side also).
I'll post the circuit here as soon as I have some time to implement it

This issue previously discussed in depth and answered.
Consumption, regardless of how many apps installed, is always 5mA in standby. From this it would take months to deplete the average car battery.
Instead of guessing, work it out
