I have a developer unlocked Focus that is currently running 7004. It was dropped in water and I assumed it did not work as all it would give on boot is the connect to PC icon.
Earlier today I was thinking "Hey I should get a second battery" Well I remembered that other 'broken' Focus and I plugged it in. Mistakenly I was holding the camera button as it took a picture and brought me to the camera screen. This allowed me to exit and browse through the phone as normal. Everything worked as normal (Aside from there being no SIM) I could even browse the marketplace.
I decided to test the apps to see if they'd work first Facebook (no good couldn't update stuff even though I was on WiFi) and twitter. After writing a tweet the phone locked up and reverted to the connect to PC screen. Now the hardware buttons do not respond (Back, Home, Search, Camera will focus but won't take picture)
Short version:Now whenever I boot up it goes to the connect to PC screen. If I connect the phone to a PC it just keeps rebooting itself. The hardware buttons do not respond if I do the reset command. (Back, Home, Search, Camera will focus but won't take picture)
Question: Is it possible to fix this issue of infinite boot and have a normal phone again?
Phone specs
Unlocked
ATT Focus
No MicroSD
Version is 7004
If the hardware hasn't been affected you can try a reflash with one of these ROMs. If you can still do that. Plus a hard reset.
From what you have described, I can't tell for sure what is wrong (soft, hard or both). Hopefully none.
The fact that the phone worked, suggests that part of the software is working. The hardware seems ok, so if you're lucky enough the phone might work with a reflash.
What I recommend, before you reflash, considering it was dropped in water, is make really sure it's dry. I hope you removed the battery quick enough as that usually damages the phone if left in, afterwards.
I've heard various methods, and I know 2 that work:
- remove the battery and the cover and find a warm/hotter and dry place (not too hot) and put the phone there, over a towel and in between the phone and the towel, kitchen towel. The idea is to heat the phone slightly. DO NOT use a microwave or a blow dryer or fire. A good example is over an electric blanket, at lowest power (+towel, +paper towel).
- dry rice. immerse the phone completely in dry rice (batt/cover removed) and leave for 24h
So when I flash the device it comes up with a connect to PC screen. However the flash does complete the entire process. Zune then starts running but says restoration fails.
EDIT: I don't think this phone is good to work anymore.

Did you re-flash the firmware or you only tried to restore from Zune?
The flash process doesn't involve Zune...
I reflashed the phone and then it reboots itself. First with the screen with the red arrow. Which is supposed to happen. Then it reboots itself again and Zune boots up, giving me that error. It then returns to the connect to PC screen once again no matter how many times it is rebooted.
EDIT: Would it matter which AT&T ROM I used to flash it with?

Hmmm.
Here's an Omnia 7 guide, but should apply to the Focus as well (evidently, with Focus ROM/binaries from Samsung-i917-Focus-firmware-UCJK2-ATT-USA.exe)
I suppose you followed it. If that's the case then your hw might be affected...
Yeah I followed that exactly. I'm guessing the hardware is affected and can't be used anymore. Guess the one time I used it was a fluke. XD Oh well. So much for having two Samsung Focuses.

I think you should ask Heathcliff74 (PM him), maybe the problem is that one of the steps just doesn't complete and maybe there's a way to force that, or there might be more you can try.
FML! I went ahead and did it! I mentioned that I hadn't had an SOD or reboot since ICS and now enraged the gods of karma and pulled down on myself a wrath unlike any other!
Yes, I have a problem that I call the Black Shroud of Death. Using transformer and the backlight goes out. I click the power on and I see the backlight go on but I don't see anything on the screen. Hmm, figure that I must have gotten my first SOD or maybe a misbehaving app is FC'ing. So I reboot, the ASUS logo flashes a bunch of times and then it goes to a black screen...backlight is still on though. It never "seems" to boot. I reboot a couple of times and it repeats the same process.
Then something odd happens, when playing with the power and volume keys I notice the lock screen for a second appears. Playing around more and suddenly I see the lock screen BUT only if I hold the volume keys. So, it IS booting but for some reason, the display is unable to show graphics. The backlight is on too so it's not a backlight issue.
I am able to unlock and I start disabling settings(I'm on Megatron) in hopes to hit on the cause of this issue. I release the keys and I'm back to the Black Shroud again! If I'm lucky, I can make it reboot into recovery where I don't need to hold keys to see options.
I tried downgrading to a different GAPPS version as I had previously upgraded and wanted to see if that's the problem. While it boot, the typical gapps upgrade screens were flashing like crazy.
I tried reflashing my ROM but that didn't seem to do anything.
My guess is that I need to completely power down and clear out some bad crap in the video memory. I opened the back of the unit but couldn't figure out how to pull the battery cable. I did manage to ruin some plastic clips on the bottom or something, so yeah the less than perfect bottom fit is now fun. So, my next step is to let it power down, charge it up and see what happens.
Any advice...other than don't enrage the Gods?

It might not be software but I can see the recovery screen so I have some reasons to believe it could still be software. Unfortunately, if I try to RMA, they're going to say that I voided the warranty....because I probably did by opening the case AND running a cooked ROM. So, they'll fix it but as a service. I'm not sure it would be worth the cost.
Wait for the next update. I tried sending it in for repair. No change what so ever. If it is software you got me beat on the weirdest ICS bug.

Yeah, I think it's some corrupted memory that sticks around after reboot. At least I hope so. When I get home tonight I'm going to charge it up and see if the power draining helped.
If not...well, it might be time to think about my next tablet. I'm interested in seeing how the "Google Play Tablet" turns out as their might be integration with home theater stuff. Then there's the updated Transformers or maybe the iPad. Yeah, I know iOS is boring as hell but it has lots of tablet apps and gets new one's first. I'm kind of getting tired of seeing...."Coming for Android".

Yea, you screwed up by opening it. You might as well upgrade if all else fails. I'd hold off on another transformer for as long as I can though if I were you...already hearing about minor defects in tf300s such as light bleeding.
Then there's always the...iPad...but make sure you update if you get one! Jailbreak that MF first and then you'd be good to go. My dad wants me to jailbreak his iPad 2, but it doesn't help that he's "update happy"

So, with some plastic clips damaged. Does it close properly now?
The battery cable should be either soldered onto the board or it uses zip cconnector. Nowadays cable/ribbon cable uses zip connector on motherboard.
And not all TF101/G would have 100% perfectly & exactly the same and this might giving you a little not so perfect in term of tiny capacitances on the board. This little components sometimes don't hold voltages that good as they should. Thus giving some trapped voltages and having your battery connected makes this trapped voltages remain in it. The best option now is to drained your TF101 completely and stay drained for another day(this is to let the capacitances drain its trapped voltages). The next time you boot and it might just solved your problem..

Almost, there's a slight bulge in the bottom but it fits on the dock.
Unfortunately, I think it's a hardware problem. I tried unbricking the device using NVFlash to load stock ICS but the entire time the screen never displayed anything. It didn't look like the entire Flash job completed and I can't get the back light to turn on now. I can't even tell if it's charging.
Anything more I can try before I chalk this up to a brick?

Have you tried leaving it for a day or two in total battery drained??
List you could do/perform.
1) NVflash works on B60 and below.. check yours
2) Put it in a freezer for a night
3) Dissemble again and see if anything disconnected or loose since the last time you open it.
4) Smell it and see if anything like burn smell around the motherboard(this could be over voltage from a weak components).
.

If all above still yielled the same result..
5) Check and see if your TF101 could survive 2 storey height drop..
Good Luck..

A lot of LCD screens can be damaged by freezing, unless you know that the TF is safe I would not freeze it.
OK, I managed to unbrick the device but I still can't see any video. Backlight is working fine and I can output to HDMI. Digitizer is also working fine as I can manipulate the screen and see the result on the TV.
So, now that I'm at stock ICS and can output video. Does this narrow it down to an LCD problem? If so, is there a loose wire I can check? Am I likely going to have to send it to ASUS for repair?

Yes, but at the time I was looking for a cable that I could loosen, now I'm looking for a cable to tighten. Fml, yes it sounds stupid but I'm at the point where I need to decide if a repair or replacement is the next step. I'm not thrilled with anything out there.
Almost exactly the same problem here...
I have a very similar problem to yours right now; the screen on my TF101 is entirely black but the backlight is on and i can output through HDMI fine. I'm still under warranty but i can't RMA it at the moment as it is running Android Revolution HD and i need to restore it to stock Asus TW firmware before they would fix it. Problem is Rogue XM Recovery is not able to output through HDMI ;p, so now i have to wait for someone to post screenshots/pictures on a thread that i started showing the menu for the recovery and the other screens involving wiping the dalvik cache and installing from zip file. Any closer to solving the problem?
I had the same problem of the backlight being on but no video. It worked over the hdmi but that was it. I had to send in my unit via a RMA to get it fixed.
Thankfully it was under warranty so they fixed it. Did you drop your unit?

Just out of curiosity, why not nvflash your way back to stock? I did because I couldn't find my HDMI mini cable. I haven't opened my tablet again. I'm going to try to RMA it.
try to nvflash stock rom and start over? that would your best chance....
Sent from my Transformer TF101 using xda premium
Well first of all i don't know how to use NVflash, and secondly i have a B70 transformer so i don't know if it will work. Also i need to flash the stock Taiwan firmware because that's the original firmware that came with it and i can't find instructions for that. Just wondering though does flashing the stock rom using NVflash also install the stock recovery?
Hi all
Apologies at coming on here and immediately asking for help, but....
I've had my Nexus 7 since July and have been very happy until NOW!
I seem to have been cursed with the dreaded flat battery resulting in n7 being stuck in the boot up.
I get as far as the Google and X icon but then stalls.
I've tried all the methods of long push of buttons/multiple buttons/etc but to no avail.
I can bring up the factory restore option so I know I can get it working again, but....
I have an exam in a week which foolishly had work stored for on my n7 without back up (yes fool) so....
Please is there anyway to retrieve my files via PC etc before factory resetting
All help genuinely appreciated
Mark
rooted vs unrooted (or unlocked bootloader even if not rooted) makes a huge difference in the answer.
Please state which.
Sorry about that
Not rooted.
It is absolute stock, nothing changed or added from purchase other than jellybean updates
Thanks Mark

Find someone with a Nexus 7, pop the back cover off and use their battery to boot up and retrieve your files. The back cover just pops off.

pleading mentions the battery, but then says "stalls" - not "shuts down", which is what you might expect if the battery was drained:

But, bigbop could be correct if pleading meant "low battery shutdown"
One other very long shot - assuming that that the device is hung - is to see if either adb or MTP are available. Normally that happens very late in the boot & I have to imagine that he has already tried that though.
Hi again guys
Firstly thanks for not giving up on my situation!
Bad explanation by me I guess....
The battery went flat/dead (my bad)
Plugged in to charge and screen lit up again but showing the 'powering off' script
Left over night on charge, wouldn't switch on again next morning
Left on charge all day still no joy but if I try switching on whilst plugged in I first get the Google name, then the Google X but then gets 'hung' (probably a better description than freezes etc as it still pulsates the colours)
Only way to get out of this is to keep power button pressed which switches n7 off and starts the cycle again
If during the recycle I keep the volume down pressed then it accesses the option screen to recover/reboot etc
Hope this helps, and again thanks (desperate to recover course work)
Mark
Hi again
Update...
Battery is showing full now
But still same 'hung' situation
Regarding the 'ADB'
I can get to the 'apply update from ADB' option
And if I choose it states.... 'now send the package you want to apply to the device with "adb sideload <filename>"'
As always thanks for any help or suggestions
Mark
Mark,
It sounds to me like what you are describing is ADB in the stock recovery, not a ADB when the regular operating system is running. (Is that right?)
Unfortunately, the stock recovery is only good for 2 things: applying an OTA update, and doing a factory reset. Even if your tablet needed an OTA update (and it probably doesn't if it is up to date), it probably wouldn't fix the looping/wedged phenomenon: usually that is caused by stuff in the userdata partition.
Doing the stock recovery factory reset might cure the wedged/looping problem - but only if it wipes all the data from your tablet. (Including the /sdcard area too).
The only hope I held out was if your tablet was reachable via a ADB or MTP with the wedged operating system sitting there looping. Usually those facilities start up quite late in the boot sequence, however so probably you don't have that.
Sorry. I think you are still SOL when it come to retrieving files.
Thanks for the help anyway
I'm guessing that with no further responses that really is the end for my work.
Unfortunately for me personally it will mean the end off my relationship with the N7, as much as I've loved it I really can't justify the obviously common occurrence of this happening.

Uhhh ... what?
The OP was about a tablet that you couldn't get into because
[a] it had a correctable soft-fault
you didn't want to exercise an available soft-fault recovery method because of a desire to reclaim user files not backed up
... and so far as we know the soft-fault recovery mechanism still is available to you.
How did that morph into "this is the end"?
You need to re-do your homework, perform a factory reset, and move on with your life.
You have used either software or hardware in the past haven't you? That thing isn't a toaster or a waffle-iron! No backups of important stuff? Come on!
OK, well then. Pack it up and send it to me with the charger and I'll pay for the shipping - UPS ground.

Just tried right now - held the Vol-down button down continuously from about 2 secs after the Google B&W splash screen appeared until the lock screen appeared. That worked. (Stock 4.2.2)
"Safe mode" appears in the lower left corner. I had access to all the market apps (that I tried), but did not see a toast notification from StickMount after the boot - suggesting that safe mode only inhibits apps from starting on boot.
I suppose this could work (although the OP's deadline has probably come and gone) for bypassing a hung boot - but only if the hang is due to a market app that normally starts on boot.
Hello all!
I would like your opinions/knowledge on how likely you think it is that my problem is a simple disconnected cable, and if it would be worth it to take apart my phone (I've never done it before.. but I'm careful) to see if I can just reconnect it.
I woke up one morning and my screen would not turn on =( I did not drop it or get water on it, although it had been very humid. The screen is not cracked and it is still responsive to touch (vibrates when touched on the soft keys on the bottom) but it is completely black, no flickers, no faint images, no nothing. I also have not seen the LED light up since this has happened, when charging or plugged into my computer or anything. My computer DOES recognize the phone, and I have used the Motorola utility to update my phone since this has happened, but that did not fix it. I have tried all of the key combinations and I have successfully rebooted it (I can hear the droid start up noise, the camera sound when I hold power and down volume at the same time, and it sounded like I almost accidentally made a call when messing with it last night).
I have not yet been able to factory restore it or anything like that from recovery, as I am flying blind, but I'm thinking this is a hardware problem with the LCD?
The phone is not rooted and boot loader is not unlocked. It's only a few months old but I bought it used online so there's no returning it or anything like that.
I just don't know enough about any of this to know how to proceed next. Any help would be appreciated! Thank you for your time!

it would still be under warranty by motorola - especially if you accepted the OTA recently (May 2013).
otherwise, I would try leaving it plugged in for awhile (30-60 minutes), then try rebooting it (hold down all 3 buttons)

How do I go about collecting the warranty on a phone that I bought used? And what would happen if it showed water damage? I swear I have not gotten any water/liquids on it, but this did happen after it was very humid out for a while, and I have read that high humidity is enough to spread the red dye (regardless of whether or not high humidity actually caused the problem)

Hi all,
I have a major problem with my Samsung galaxy tab 4. When I power on the tab sometimes it will hang on the splashscreen.
Then if and when I get through the frozen splashscreen the screen will flicker extremely badly, almost like interference and will freeze.
I done a factory reset, disconnected the battery, still the same issue.
Any ideas what the issues are?
Thanks in advance

I would find the correct firmware for your tab (from the Samsung site) and reflash the full Odin tar. If that doesn't help I'd contact Samsung about the issue.
Is there any point in getting in touch with Samsung after opening the tablet up?
There is horizontal and vertical lines approximately 5mm apart, coloured.
I can see the logo behind these lines but and the whole system has frozen.
This still happens after a factory reset which makes me think it may be a hardware issue.
Would it be a digitizer issue?

Is there any point in getting in touch with Samsung after opening the tablet up?

That would be your display, not your digitizer. since you're thinking of opening the tab, check the connector
to the board from the display screen, just be patient, steady handed, and keep a light touch.
use a magnifying glass of you can't see the layout clearly, the connector may be seated wrong/crooked
there should/may be clips on either side that need to be slid out before disconnecting the ribbon.
I would get a replacement if you haven't opened the tab already.
questions belong in q&a. :good:

just a thought, check for moisture/corrosion anywhere, at the point you open the device, you're pretty
much S.O.L. but hey.
Yes unfortunately the Tab 4 has been opened.
By disconnecting and reseating the battery sockets i believe the warranty is void. The back has been opened.
I find if i get the device running momentarily then by gently plexing "twisiting" the unit in my hands can cause the screen to switch back to normal.
But soon after the dreaded horizontal and vertical lines appear then the device becomes frozen again, the intermitent lines jump around the screen with whatever is in the background leaving the display frozen.
Only solution is to gently open up the device and disconnect the battery and then reconnect again.
This is only a temporary solution as the problem reappears very soon after.

So you reckon it is not the digitizer that has failed? I was thinking of replacing that.
Hmmm..

I'm not so sure after what you said about twisting the tab, can you get into the system through adb ?
After the tab "freezes" hook up to your comp and get adb shell running, run any/all of the following
logcat -d
mount
ps
dmesg
and do some directory hopping to see what you can access, reason being we narrow it down to display/digitizer/something loose on board.
just to refresh my memory, the same behavior occurs in recovery ?
also tap your power button to screen-off/lock.
and at the end after adb test, force reboot to recovery with button combo.

I'm unsure about your suggestions, as i don't know were to locate those commands.
I have done a factory reset, so i am just waiting for the device to charge before attempting to load new firmware through Samsung Kies which i downloaded through this link... http://www.samsung.com/uk/support/usefulsoftware/KIES/#versionInfo
are the commands you suggested within the Samsung Kies software?
ahh, no. You need to run adb on windows [ewww]
or adb on linux [yay!]
can't help you with windows.
but what about in recovery ? did you encounter the same issue or no ?

When i was having the problems initially, i could not for the life of me get into recovery mode using the button combo's. Eventually i did get into recovery, so as a last resort i cleared cache, and done a factory reset. Now it is booting up as normal but i was going to use Kies on windows to see if it is a software issue.
So were do i go about getting
adb
logcat -d
mount
ps
dmesg.
And what would you suggest as a step by step guide from were i am at now?
Note: i haven't physically messed with the device to see if the Horizontal and Vertical screen issue is still there.
Thanks

i tried running adb but i'm getting unaturiosed, clicked on the revoke debugging and then adb just ran through all the commands.
then the device screen problem has arisen again and i can't get it to boot.

You're not supposed to revoke adb debugging.
Look, i'm at a loss, the thing is, do you blow more cash on a quess, or cut your losses.
As to learning how to use adb, XDA searxh box, using adb.

not a bother.

sent you a message on hangouts. thanks
Flashed the stock kernel using Odin, i hope that gets rid of the screen issue :fingers-crossed:
Well 3 hours later and the Tab is going good
My daughter is delighted that it's sorted and she hopes it stays that way
Many thanks to Moonbutt74 for your time and effort, it's very much appreciated.
Would you say that it's good to go? And is there anything else i need to do to the device before handing it over to her?
Cheers
