[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] Black screen of death?

Here is what happened on my month new Galaxy Nexus.
1. Listening to mp3 via Bluetooth headset
2. Playing a game
3. Standing up
4. On a train
Sound stopped working across everything, in the game and on the mp3. Tried killing the applications and reloading, the mp3 player refused to even start the mp3.
Rebooted the phone, well, I turned it off. It has never turned back on. Tried removing the battery, all that, nothing.
Got home, tried plugging in the USB into a PC. Nothing. Tried booting into recovery mode, nothing, other than the PC claiming to have found a new device.
I haven't plugged it into a PC in recovery mode before. I haven't even seen recovery mode on the Galaxy Nexus.
I was running OTA Vodafone UK 4.0.2 I hadn't even considered rooting it or anything.
Anyone know if this is salvageable or had the same happen to them?

Hi. If popping the battery does no good I'd get it replaced without any further investigation. Sounds like hardware fail, so long as you are sure you have not got it wet or caused any damage to it.

If you cant bring it back on after a battery pull then its a dead phone for sure

I had the same problem last month. An usb jig solved the problem.

USB Jig?
Any more details? Something you can point me at?
Cheers

Appropriate?

So does the phone show anything at all? Does the screen come up for any amount of time? Can you get into bootloader?

So for completeness I have exactly this issue:
http://forum.xda-developers.com/showthread.php?t=1384415
Basically this paragraph:
An item under "Other Devices" called "OMAP4440" keeps appearing and dissapearing all the time, with the little "!" mark next to it indicating that there is a driver error. The drivers for this phone are fully installed on this same PC, and it use to work fine before it went dead.

Sounds like a USB Jig might do it. But in this case its back to vodafone and jumping through those hoops.
For the record I hadn't done anything at all to the phone than a normal consumer would. i.e. no rooting, hacking, booting, fruiting or cheesing.
It just died.

[Solved] Cerberus not playing nicely with HOX?

I received a HOX that appeared to be DOA - not able to power on, no LED when charging. Nothing. I plugged it in for a while to see if it would miraculously start charging, and surprisingly, it did after a few hours.
It booted up normally and I began to check the apps. All looked fine and dandy and I threw a SIM card into the phone to check the service. Powered off to restart - and the phone died again.
I left the phone plugged in for a few hours. DOA. I popped it open and pulled the battery connector to reset. Put it back together. Still DOA. I left it unplugged for the night and plugged it back in the next day. The charging LED came back on! It booted up! I checked the apps again, and uninstalled everything that had been downloaded. The phone was not rooted and completely stock. The only app I was unable to uninstall was Cerberus. I attempted to hard reset the phone and of course, it would not turn back on. To me, this seems like an issue with the software security.
I emailed the customer and had him disable the device administration. I'll be able to check again in another 24 hours to see if I can uninstall and see if that does the trick. If that doesn't work, it's RUU time.
My question to you all is, are any of you using this app with the HOX? Could this be the root of the issue? Or has anyone had a similar issue with this phone?
Thanks in advance for any input.

I'm using Cerberus and don't have any problems with it. I think you do have to disable it under device administrator before uninstalling, but from your description, there are deeper problems with the handset. I'd get it replaced under warranty.

That was indeed the issue. Maybe it was potentially a bad install, but after it was disabled and I was able to uninstall it, the phone began to work immediately.
I'm going to hold onto the phone for a few more days to ensure it's good, but I caution others about downloading this app.

Never had any issues with Cerberus. Granted, I am rooted and I flashed it from recovery instead with the zip file on their website, so nobody can uninstall the app without overwriting my whole ROM. More than enough time for me to get a picture of the thief, wipe my phone, and get GPS coords

Good to know. The phone I had here wasn't rooted, not sure which method he used to download it. But I guess it was the wrong way!

[Q] Help!! a100 Blackscreen

i have a a100 with the latest flexreaper rom installed and im stuck with a pretty serious issue:

im at my wits end on what could be wrong and now i got my wife with her foot on my neck till i get it fixed. can anyone help me?
ive tried to do a hard reset with the reset button tried to boot into recovery /bootloader no dice

It may take awhile for someone to see this and form something to try, random bricking for no reason is rare, its almost always some error by the user. However have you attempted adb connection to it? Leave it powered off, connect to the PC you used to unlock the boot loader then power on. Does the PC make the USB connect sound? Does the Acer vibrate? Did the home key blink again?
It really sounds like your boot partition is wrecked which wouldn't normally happen outside of flashing. If boot loader is trash then it won't know what to do and just sit there. No recovery or anything else.

it made something like the connect sound but instead of the regular duh doom sound it did a dadadoom (kinda hard to describe the sound) but it was faster than ive ever heard the connect sound before which is weird. the tab didnt vibrate and it seems the home button blinks when the tab is dead and needs recharged

Yeah I know that sound it means USB connected but error for some reason. Its been shown if this thing dies all the way down it wont read the battery correctly and probably needs to be sent in. Before that I personally would unplug it open it up and remove the battery for awhile, maybe an hour then put it back and plug it in. But thats me, not the advice I'm giving. If you have warantee on it use that.
The batteries on a lot of devices and laptops etc have something of a fail safe, if the voltage drops below a certain point it trips to prevent cell damage, however it renders the battery useless.
I haven't searched out much past that if a reset is possible by us, but it seems the pack is trash after or needs sent in.
Since this is a sealed unit you void warranty opening it (well unlocking the boot loader did too) so you can't send it in for repairs without paying for it.
I hope someone can jump in and help figure this out, and prove me wrong.

Weird, This exact same thing happened to me. Used it in the morning and now after work it won't turn on. I had already tried disconnecting the battery, but hadn't thought to leave it disconnected for an hour. My tablet has been running the leaked ICS since it came out and The last factory reset it had was about a month ago. It was working fine up until this. The power button seems to be responding correctly, the issue is that after the LEDs light up, there is no vibration or display. I hope someone can help us with this issue.
EDIT:
It won't connect in ADB mode. It will only appear on my computer as an APX device and since there is no vibration I am unable to boot into fastboot. Any help or suggestions? All the threads I have found have involved booting into fastboot.

i am also having this problem. i set ti backup last night to save to box i turned it on this morning it.worked set it on the charger came back to a frozen screen. I turned it off now just a black screen it turns on or the home button dose but nothing comes up on the screen

A100 blackscreen
i am also having this problem. last night. just a black screen it turns on or the home button dose but nothing comes up on the screen. :crying: Help!!!!!!

Has anyone tried holding the power button for a while? Laptops do this too, if someone felt ventures, try taking the battery out and hold the power button. No promises, might work.

Having the exactly same issue, here...
I also tried to hit the hardware reset button and it does not help.

If the screen is blank while powered on its in failsafe mode, in other words is bricked, has to go to Acer.

This just happened to me a few weeks ago as well. If you are still under warranty send it in to Acer, thats what I did. I just got an email saying they had fixed it and were sending it back for free!!
At the time I was on the 9/02 JB build. I wonder if this issue is caused by faulty hardware or if it is an issue that was made by rooting and unlocking it? I don't know enough about this stuff to answer that though, but it does make me think whether I should root/unlock it when I get it back or leave it stock.
Also thanks Pio_masaki for helping me a few weeks back wasn't sure if I was even going to send it in until you said they most likely won't be able to tell.

I highly doubt they even CARE when sending these in. They will void for physical damage most likely.

Ohmygod,
Same here, but it's 3 years ago. Sorry for digging the topic. Still no hope? I still keep the tablet and have just buy another refurbished mainboard to replace but still no vibrate and blacksreen still there.

Galxy s2 Vibrating and crashes at loading bar.

So i've looked around and no one that i've seen has the same exact problem as i do. Here's my post in another forums about my problem.
Here's my story about my Galaxy s2 for T-mobile. My phone randomly turned off 2 days and whenever i tried to turn it on, it would restart and basically never get pass the blue loading bar screen. Second, i found out about this boot loop sequence and i was able to do a factory wipe.
After i factory wiped the data etc off the phone, i was able to use it until it ran out of battery, but then after i found out it ran out of battery, it wouldn't let me turn it back on, it wouldn't get pass the loading screen, once again. On the other hand, i am able to go to recovery mode or download mode, but the phone shuts off before i can even try and click on the options i want.
Today, i found out that if i kept pressing power button consecutively on the phone, I'd be able to go to my home screen and basically act as if nothing ever happened, it'd function as a new phone! I then had the nerves of turning off my phone just to make sure it finally works now, but my hopes were crushed and now the pressing the power trick does not even work anymore. It would probably work one out of 10-15 times, and in the end it'd still restart. I am using a gingerbread galaxy s2. My friend tried using the usb jib on my phone, and it worked but whenever he tried to plug in the usb, the phone would just restart. I am extremely frustrated with this, and if you can help, please do so because it's important that i fix this phone. If you have any questions, please feel free to ask!
Hi there, thank you for the welcoming me to the forums. No, my phone is not rooted, it has always been gingerbread etc i never tried rooting because i never knew how:/ I believe this started when i was just browsing around facebook, so i'm not entirely sure what happened... Uhmm i tried going to download mode through the volume keys and power button when it's connected to usb to the i think it's odin3? and it'd be in the download mode but as soon as the computer says it's connected, the phone would just turn off again and bam, it's like nothing ever happened. My phone does charge when it's plugged in, but it doesn't show it's being charged but i remember my battery was dead last night and i charged it till today and now it's got power. ANd no i don't have a warranty:/ i really hope you can help me

Sounds like a faulty power button. Check out Mobiletech video for thier power button repair service.
