[Q] Working brick?

So I have been a long time follower of XDA, did all sorts of things with my Vibrant and just recently got the SGS2 from Sprint. A few days ago I flashed Calkulin's E4GT v2.6 and since then everything has gone down hill:
> The phone started acting like it was "charging" with nothing plugged in, red LED light stayed on and the battery had the charge symbol.
> Car mode began coming on over and over again.
> The phone would freeze and after I took out the battery it would automatically restart with me pushing the power button once the battery was re-inserted.
In hopes to just be down with it I flashed it back to stock with ODIN and everything seemed fine...
Now the phone is constantly freezing, Displaying that I have no service, The touch screen becomes unresponsive while charging, Car mode is still trying to launch.. not as frequently but it has happened. Other minor issues was the pattern lock would display when I woke up the phone even though I never set one...but I could do anything with the pattern to unlock it, even just touching a circle. Worse part in my opinion is either the phone will not recognize the PC or the PC will no longer recognize the phone so I can try ODIN again, same PC, drivers and USB cord being is.
Any suggestions on how I can remedy the situation?

Same thing happened to me, when I tried flashing an AIO over Calkulins you're pretty much done. You'll have to unroot and go to sprint. I ended up getting a new one since I was within the 2 week exchange.

What exactly did you use when you did this? I flashed it back to stock with ODIN
Maybe link to the file(s) you used?
Also maybe the exact steps you took. None of this sounds right. And if you flashed the complete EG30 tar you would be back exactly to when you purchased the phone. Everything would be overwritten so there really wouldn't be anything left to linger and cause issues.

Try a ##786# reset

Once the device started acting funny, I basically pulled out the battery until I got home where I could flash it back.
This is the stock files I have saved to my computer:

The phone is still somewhat usable, 3G, voice calls, everything works as normal until some of the symptoms start up again. Primarily the issues I am having is the phone completely freezing and occasionally displaying no service and of course not recognizing any PC connection.

Try a ##786# reset from dialer.
To get your MSL, in adb shell, type "getprop ril.MSL" without the quotes. If you use Android Terminal make sure you aren't using the Swype keyboard or it'll auto capitalize the "I" despite being told not to.

Initially, sounds like the USB port has some **** in it or damaged ;p

First off thank you everyone who has replied, I have definitely looked into all of your suggestions throughout the day. Here is what I have come up with.
I tried the ##786# for a clear reboot, all the symptoms still continued =(
I started figiding with the micro USB port and finally was able to get my computer and phone to connect to each other, I have also been reading that the port also causes the phone to spontaneous "ghost" charge and activate car mode.
So I am pretty sure it is a hardware issue, in particular the usb port. Tomorrow I am going to get the parts and make a jig to reset the binary counter and just take it in to Sprint and get an exchange.

[Q] Help Dealing with Unresponsive Screen/Buttons (Probable Water Damage)

On Friday night, My phone was in the breast pocket of a blazer that got very damp in an unexpected downpour. The phone continued to work on Friday night as far as I recall (I wasn't using it much, but I'm pretty sure I did use it some). When I woke up on Saturday morning, it appeared to be off and wouldn't turn on. I pulled and replaced the battery and still got nothing. I put it on the charger, but I had to run out, and I ended up being gone all day.
When I came home, the power button still wouldn't turn on the device. I pulled the battery and replaced it, and the Google screen came on, then the CM10 boot animation. When it got to the pin screen, however, the screen wouldn't respond to me entering my pin. Then, after a minute, the screen turned off, and the power button wouldn't turn it back on. I did a battery pull. Again, replacing the battery brought up the google screen, the CM10 boot animation, and the pin screen. But, again, the screen was unresponsive, and the power button did nothing when the screen went off.
I took it apart and left it alone all day Sunday. On Monday morning, I tried again and got the same results. I went and picked up a bag of white rice yesterday and left it in there last night and all of today. Still, I've got the same outcome. Buttons and screen are unresponsive.
So I'm left with a couple of questions:
First, is there anything else that can be done? This seems to me to be water damage. Does anyone have any suggestions for possible solutions?
And second, I keep getting text messages. Is there any way to pull those messages using the Toolkit or adb or anything (I'm pretty inexperienced with adb)?
Any help would be great. I'm stuck in China without a phone right now, which is a pain in the butt. I'd like to revive this, and I don't want to go track down a new phone until I know this one is sunk. Thanks for your help.

install android-sdk
run adb server on the host
connect your device to pc (feed it naked drivers manually found on dev section, if you're on windows and device manager shows unknown device)
type: adb devices
q: do you see your device listed? (should be lots of numbers and letters)
if it doesnt even recognizes that it has been plugged in, then your usb connection went down the drain, nothing else you can do

My computer recognizes the device, and I'm able to do some things using the toolkit, such as a manual reboot, so I think my usb port is intact.

And you would expect this to resolve the screen and buttons being unresponsive? This is interesting. Is it possible to pull my messages beforehand?

a very strange hard brick

Hi!
First of all i got AOKP + Franco kernel for 2w without any problem and I didn't change any option since last week.
This morning i rebooted it, it switched off and it didn't start again.
I cannot switch one my nexus again since then. I have always a black screen, also if I try to enter in download mode or in the recovery.
I tried to connect to my computer and smt times my laptop see a omap4400 (i'm not sure about the name) but after few second it disappears.
Tomorrow I'm going to the service center... But I have a big doubt:
What the hell happened this morning?
Thanks

Remove the battery for 5 minutes and try again.
If that doesn't work,
Follow this guide:
1. Download the zip file from http://forum.gsmhosting.com/vbb/f634...eeeee-1465412/, created by Legija
2. Extract zip to whatever location you're comfortable with (I used Android directory)
3. Open up Device Manager (Hold down Windows Key, press R, the type in devmgmt.msc and press OK)
4. Go to actions menu, select Add Legacy Hardware
5. Choose install manually, then have disk. Browse to where you extracted the zip, select the 'inf' file in usb_drv_windows
6. Choose OMAP, you'll get a popup if on Win 7, continue anyway (driver not signed)
7. Once completed with driver, pull battery out of phone, then plug it into USB
8. Double click omap4460_tuna_hs_pro.bat to start the process
9. Once completed, unplug from USB, put battery back in, and power-up!
10. Extra step - depending on what's been done, it may 'brick' again - suggest to do a restore or a wipe reinstall afterwards to be certain (mine bricked again next reboot)

I'm having the exact same problem. I saw my phone at maybe 10% battery in the AM, said screw it and let it die, woke up this morning and plugged the phone in and nothing. No LED light, black screen, completely unresponsive. I've tried every trick in the book, and the only one that seemed to work marginally even was using a different battery, which got my phone to boot to the encryption screen, but then shut off again. It did that twice, and now both batteries are useless.
I used Legija's program to try and bring some life back to my gnex, even though it's not the international version, just in hopes of getting some of my data back (I have already started the replacement process with Verizon since the phone was insured), but I got no luck there either.
It's extremely disappointing and annoying to me that this phone survived all sorts of ROM installations (I was also using AOKP on 4.1 if someone wants to start making connections), reformatting, tweaking, almost every setting on that phone was modified by me.
Not only that but almost any software or hardware problem I did run into I could solve in maybe an hour, but I let my charge run out and the phone just up and bricks itself? Now, that's just bull****... I would be very curious as to an explanation as to WHY on earth this would happen. Very confusing.
Not to hijack the thread, but my interest here is not restoring the phone to working condition but just seeing if I can pull my data off of it. I wouldn't even be posting here had I been able to have an SD card with my gnex, which I figured was unnecessary at the time I bought it since I knew the space on their was enough for me already, and the added branding of "Nexus" brand which had me under the impression it was maybe stable enough by itself. Not a mistake I'll make again..
Is it at all possible to get the data off of my phone at this point? At least partially? I believe encryption makes it impossible but I'm rather stubborn. Any help would be greatly appreciated..

So just to be clear... You've been able to get it to boot all the way up to the encryption screen, right? If so you should be able to get into fastboot (Holding down BOTH volume rockers and the power key.) From there you could relock/unlock the bootloader to do a full factory wipe which might solve your boot issue.
As far as the data loss from the wipe, you could then try this: http://forum.xda-developers.com/showthread.php?t=1994705

I was able to get it to the encryption screen with my old battery that had a little bit of charge left in it twice, but it shut itself down on me both times. So now both batteries are useless.. I took it to the Verizon store hoping they would maybe try one of their batteries, but they just called customer service and told me they're just going to replace it at this point.
I have a feeling the charging mechanism is somehow damaged, because when I did get it to the encryption screen I had it plugged into a wall outlet and it wasn't charging at all. So, I can't turn the phone on whatsoever anymore.. if I could turn it on I could solve this problem... but it simply refuses to boot. The closest I came to interfacing with it was the OMAP Flash script, which did work, but didn't fix the problem.
So maybe if I could get the phone working enough to use ADB with it I could get my data back, but not even that seems possible..

If the phone isn't charging then there's something wrong with the USB port. One way to test that would be to use a battery charger. Also, try a different cable. I've had issues with a few different cables that for whatever reason started to not fit properly in the phone.
If you're USB port has gone bad then you'll need to either A) Always use an external battery charger. B) Get a replacement. C) Fix it yourself (Good guide here: http://www.ifixit.com/Guide/Repairi...+LTE)+Micro+USB+Charge+Port+&+Main+Mic/9641/1 )

[Q] Black screen and no booting.

So the other day I let my n7 die completely, which has happened in the past. Today I went to charge it with my computer and turn it on, so I plugged it into my laptop's USB port. For reference, I just installed Windows 8 and there are no android drivers on my laptop. Anyway, I plug it in and hold the power button and it shows me the google screen, then it goes to a black screen annnndddddddd.... Nothing. It stayed there until I did a hard kill. I can get to the bootloader as well as TWRP. Within TWRP I cleared the caches, and ran a fix permissions. Nothing. I've backed up in TWRP and have yet to wipe my data because that's a last resort for me at this point. Right now its sitting on the charger. When I plug it in I get the battery thing as well as the battery charging thing, however after the battery charging thing goes away I can't call it back up. (usually it'll go away but you can hit the power button and it will come back).
This appears to be a hard brick but I'm not sure. I was running 4.4.2 stock, rooted, bootloader unlocked, with Gravity Box, but that's it. Otherwise I've been running normal user stuff and it has been (up until now) just fine, normal battery life and everything.

I fixed it. Something happened between the battery draining completely and me trying to turn it on that was causing a /system mount failure, thus the black screen after the bootloader. Here's how I fixed it:
I downloaded the full restore zip from Google (Mine was KOT49H at the time of posting this).
Then I opened the package, and the second package within the first one. I extraced the system.img file to my desktop.
After extracting the system.img file, I used fastboot on my computer to flash the system in my bootloader, and now its back to normal. No data was lost, nothing broken. I re rooted and everything seems to be in working order.

Good job! I know none of my 1st gen N7's liked to be drained completely so I make a big effort not to. Phones don't seem to have issues like these tablets sometimes do.

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?

I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.

I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:

can you downgrade to Android 5.0.1 and help me with my problem?
its something completely different to this topic

I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.

Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)

Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.

My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.

Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.

Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.

Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.
