[SOLVED (KIND OF)] Transformer display dead and stock ROM installed - warranty?!

Guys, thanks to all of you - especially frysee, who was a big help via Gtalk - the biggest part of my problem is solved:
My Transformer is still bricked and display won't turn on, but I was able to go back to stock ROM and wipe all personal data. So I won't get any trouble with warranty
If anyone is interested, me or frysee could write a How To for returning to stock ROM and retrieve warranty when screen is dead.
Thanks again!

Hi Guys!
I have a problem that is pretty common over at MoDaCo, but I haven't read anything about it here.
My Transformer sometimes doesn't turn on or wake up from sleep mode when turned on already. You can push the power button endlessly and nothing happens. Then suddenly it'll turn on as if nothing had happened.
I had this problem the first time right out of the box, so there's no bad software installed by me, don't know what ASUS did though. Perhaps it's one of the pre-installed apps.
As I said, normally it eventually comes to life again, but now I couldn't turn it on for a whole day! After I had no success, I left it on the charger over night, but still nothing this morning.
I feel I tried everything, pushed Vol Down + Power to go into recovery, pushed Vol Up + Vol Down and plugged USB to go into (useless) flash mode just to see the device to something, but no.
The only things that happen, if I push power:
- if I plug USB, the Windows plug and play sound plays and if I force shutdown the Transformer again (long-press power), the unplug sound plays. The device even appears in the Explorer and I can access SD card, but it only shows empty folders, no files in them.
- When I force-shutdown the device, I hear an internal "click" sound, similar to the one when you switch from front to rear camera, and you hear the speakers turn off. So it seems to initialize everything and stuff...
But all the time the Transformer screen stays dead
Any advice? Really need your help here guys! At MoDaCo there's no answer so far...

I was initially having this problem with my Transformer (it would usually happen when it had gone on standby and it couldn't get it to turn back on again) until I ran the ASUS updates on it - have you been able to update your Transformer on the occasions it did turn on for you?
If you've rooted it and stopped the OTA updates going onto it, you might just have to undo that and get an official ASUS firmware build on there to help fix the problem.

Hi!
First of all, thx for your answer.
Well as I said, the first time the problem occured, the device was out of the box and untouched before. So I don't think it has to do with something I did.
For me it normally also happened when device was in sleep mode, except the first time out of the box
I installed a custom ROM + Clockworkmod Recovery after that, hoping it'll fix the deep sleep problem. And it really didn't happen again - until now
I didn't turn off OTA updates as I first saw that thread when the device was already dead Perhaps it tried to OTA update itself but I guess I would have to confirm this manually right? And I didn't do that...
Reflashing another ROM or the stock ROM was my first idea, too. But hell, I can't even go to recovery! No matter what I do, press, plug or unplugg, the screen stays black!

Nice, another german Transformer
"playing the plug and play sound" means you propably have adb access? Tried getting a logcat?

adb gives me "device not found". even though i'm not a total noob, i don't know what i have to change to make it work. any advice? sadly i'm working while my tf is charging @home so can't really try something. i only hope you guys have some ideas

Ahh. I didn't realise the screen was completely dead, I thought you had it working some of the time as had happened to me.
If you're seeing it in Explorer, maybe it is just a hardware failure and you'll have to get Asus to look at it...

no i guess that it is indeed the same thing that happened to you, sometimes it worked, sometimes not. only this time it doesn't come back from the not working part I guess you see yours in explorer too if it troubles to get out of deep sleep. i guess it's just the screen that sometimes doesn't turn on for all with that problem. but for me it doesn't even turn on for booting

It's possible. I don't think I tested connecting it to the Explorer while the screen was off, I assumed it just wasn't on.
Can you test it with the HDMI out and see if that shows you what would be on screen?

Yeah, good idea! Will try this asap when I'm back home. Do I have to press something on the TF to enable HDMI output or is it enough to plug it in?

When it seems dead, try holding the power button for about 5 seconds (or whatever time you hold it for when turning it off)
Leave for about 2 minutes then hold power button again (like you do when turning device on) and it should boot.

I guess so
I'm getting a mini-hdmi cable today to determine if the screen is broken, because i have the feeling that ***** is booting but not showing anything...But I'll have to send it to ASUS nonetheless. Has anyone ever sent a device in for warranty reasons with custom software (CWM, Custom ROM) on it? What kind of trouble will I have to face?

I'd say try it with the HDMI cable, see if you get anything up on it and if the touchscreen/everything else still works, see if you can get the latest official ROM on there, see if that fixes the problem.
If nothing else, you can then send it back with an official firmware on it.

Try holding the power button for 5-10 sec, then press power + volume down (might be volume up - try both) together for another 5-6 sec. You'll get to a reset screen where it asks you to confirm if you want to wipe everything. press volume down (I think!! - read the screen carefully) instead to boot normally.
hope this helps

Its 10+ seconds for a full power off by the way, nothing shorter than that. If you changed any system files either by flashing or by pushing via ADB then you will have invalidated your warranty. Unless you can restore it to the way it was before you fiddled with it, you'll have an expensive paperweight.

Big bummer And sadly there are no "ASUS Stores" around where I could use a stupid employee who has no clue and is convinced it's hardware related.
Well I don't have my HDMI cable by now and will try this first, but if that doesn't work:
Can someone give me a step-by-step how I can access the restore function of CWM without seeing anything on my device? I did a backup in CWM before installing the custom ROM. Perhaps tell me sth. like this: "press power+vol. down on start, then after approx. x seconds press vol up, wait a bit to make sure CWM started, press vol down twice, to go to recovery, ..."
And can someone do the same for the stock recovery to reset the device? Perhaps there's a chance that a failed OTA update deleted CWM an there's the stock recovery.
I know the chance to save it like this are small, but otherwise a lot of money is lost
Regards,
qwer23

On the flip side however, you could probably make some money by being the first to dismantle your device, and sell the photos of the internals to some website like iFixit. Then you could also sell it off as parts on eBay. Obviously it might take more effort than you are willing to give it, but at least it's another option.
If you do decide to open it up I would love to hear what mA rating the battery has on its label. Not being able to find out the actual proper rating from any site has been driving me nuts. I believe it's 6800mA but im not 100% sure.

Phone Won't Turn On After Reboot

My phone has the 11-20 build of Gummy on it, I just updated the firmware to MJA (hoping to get data) and it was running well for the past hour. I rebooted to recovery to try installing the Euroskank rom and now my phone will not turn on, it had more than 90% battery when I rebooted so I know that is not the issue. When I plug or unplug it from my computer, it will acknowledge that something was plugged in (by making a sound) but not show what was plugged in. Any recommendations as far as what I can do to fix this?

I held down the power button long enough to watch a couple plays in the Ole Miss game, pulled the battery and put it back in, no luck. I plugged it in and did not get any battery notification. I did find that by holding the power button while it is plugged into my computer it seems to power on and off on some level because it would alternate plugged in and unplugged sounds, still with nothing else being shown like the option to view files or see anything on the phone screen. Is there anything else I can do?

Well all you can really do is make sure your USB cable charger is working, let it charge without touching it for several hours, could also be a battery problem /hardware problem? Any one else? Have any advice??
I have bricked my phone pretty bad a few times, but I have always at least had the battery icon on the front show up,, hopefully a full charge well cure it,, just Checking but by power you mean the top right botton if the phone is facing you?

Not from what I can tell. The screen doesn't show anything, the LED doesn't light up. Is there a trick where I could trigger it using ODIN or HEIMDAL?

Put battery in phone and charge for 2 to 3 hours without turning phone on.
Take battery out of phone and leave it out for 1/2 hour.
Then put battery back in and see if you can get into 'Download Mode' - Hold Home Button AND Volume Down Button at same time and while keeping them held Press the Power Button till you get screen asking if you want to go into Download mode by confirming with a Volume Up press.
If you can get there maybe you can use one of the Odin/heimdal methods to recover.
Or even more simply - Odin Philz recovery and flash an MJA ROM - That's something I'd try first if you can do that.

I just charged my phone over night, pulled the battery for an hour and still no response from my phone what so ever. I would be ok with a total wipe if at all possible at this point as it does not seem to be booting at all. Could this be a bootloader issue somehow? I updated the firmware not long before this issue occurred and it booted up from that for awhile and this issue started after trying to reboot.

At this point, your best bet is to take it to Sprint and get a warranty replacement. Not much you can do if it won't turn on

Ok...just curious does anyone here have Ting and have tips about doing this through them? I don't actually have Sprint directly but use Ting.
EDIT:
For anyone following this, potentially in a similar situation, I found this service which I hope to hear back from soon, it says they can fix hard bricked phones on their site:

My sister's S4, which is running stock unrooted 4.3 is going through the exact same thing. The Sprint corporate store told her that she needs to have it serviced by Samsung >.>

Why don't you make a usb jig and force it into download mode,I think I seen a video on you tube on how to make one,I haven't tried it myself but I heard they work

Just checking, didn't see this confirmed. The screen is non responsive currently, but you said that using the power button yields USB acknowledgement..
Have you tried a complete power down and boot in to Download mode (Power + Volume Down + Home) and then plugging it in and seeing if ODIN recognizes it in Com? It is possible (although not super probable) that you are experience a flash screen/screen on issue that could potentially be repaired by a reflash.. I know a lot of the 4.3 updated were experiencing lack of flash screen but if left alone the phone would still boot.
Worth a try, if you haven't already.. Stranger things have worked for me in the past.

We did the first two steps you mentioned, got it to turn on, then it it did the same thing again after a little while. We repeated the two steps, factory reset, and all has been well for the past 24 hours. Thanks

Glad you got it working!
And thanks for reporting back here so that others may be helped. Keep the comunnity alive.

Yeah, I've been seeing other people having similar problems after updating even on other carriers. My guess would be that the problem is related to going from 4.2 to 4.3 coupled with user data/cache of system apps and Knox, but I really have no idea. Anyway, Thanks again

Well scratch that, it's back to its usual behaviour. Could flashing via odin fix this or could it be a hardware issue? I still feel like it's related to the 4.3 update.

Re-flaching Odin may fix it.
But it could very well be a hardware issue. I've had a couple of phone with batteries that were fairly new have this issue. Got new battery, charged and replace it and all worked.

[Q] Please help! Phone is inbetween soft and hard brick!

Hey guys,
This is my first time posting, although I am constantly on the forums looking for help and ROMS. Its been about 4 months since the last ROM I downloaded for my phone. Its actually been 4 months since I did anything to my phone. I found a ROM that worked and kept with it. I have a sprint galaxy s4. fyi.
But yesterday while I was in the middle of texting on my phone it randomly shut off. When I tried to turn it back on nothing happened. Then I pulled the battery out and it rebooted showing the Samsung Galaxy S4 screen for about 3 seconds and then shut off again. I tried another working battery and still nothing. So then I pulled the battery out and try to get into the bootloader (holding down the volume up button). It said it was going into the recovery but then shut off about 3 seconds in. So then I tried holding down the volume down, home, and power button which allowed me to go to the OEM(I don't know if that's the correct term but it was a warning about tampering with the software) So I pressed volume up to continue and it immediately shut off again.
I cant get passed anything for about 5 seconds in without it shutting off. It's extremely frustrating and annoying that I literally cannot do anything with it.
Any sort of help or input would be greatly appreciated! Thanks so much in advance!

Make sure you have a well charged battery. Once this happened to me the phone was running hot and the little charge it had was wasted trying to get it to download mode. also having it connected to a computer/power outlet sometimes messes with the boot up. The timing of when you press the buttons also affects the loading. as soon as you see hte Galaxy S4 logo let go of the buttons. Hope this helps/.

Hey BIGSAMDA1ST....thank you so much I looked at it more closely and it seems like the button half of the button is jammed up in there.

Hopefully that's what was causing the problems. ?

Same probleme here (also since yesterday)
Could you solve the problem? I had the same problem yesterday. Galaxy S4 with CM 11. Suddendly the phone rebooted and it just came to life for about 3-4 seconds after taking the battery out and in again. After a few tries it booted coorectly again. But today the same thing happened and now it's dead for about 3 hours. Now I am going to buy an external charger and try to load the battery to 100 %. I also disassembled the phoine and checked the powerbutton for functionality.

Yeah that was not the problem. lol I'm sending it to an outside company due to the face that its not under any warranty. I'm saying its bricked lol

2012 Nexus 7 in APX mode - HELP

So I was using my N7 as normal last night, starting up Kodi (Previously XBMC) to watch some shows before I went to bed, and as Kodi was starting, my tablet froze. I let it sit there for a good 10 minutes, nothing happened, so I proceeded to hold the power button down to force it to reboot, it turned off, and now it seems to be off forever..
It is showing up in my device manager as APX. I've tried all the tricks of holding down the power button + volume button to get into the bootloader, and it just won't give in. It is rooted, and it's been that way for a long time..
Is there maybe something that I missed in my research? It seems that there are two results; those who can hold down the power and volume and get into bootloader and go from there, and those who never revive the N7.
What are your thoughts?

Mine did this...Stuck at the Google Boot Logo and when I rebooted all i got was APX mode. Unfortunately for me the only way I got it fixed was to buy a Nexus 7 from Ebay with a broken screen for parts. Then I removed the motherboard from the broken one and replaced my bad motherboard with the good one. I tried everything before going this route.

Just an update:
I never was able to revive the old girl. Tried just about everything short of reflowing the board.
I found a logic board on ebay for pretty cheap and dropped it in, it works great and now I have more space! I used to have a 16, now it's a 32.
Also, I put Cyanogenmod on it, and I love it. Much more responsive than it used to be.

Another update, she's still going strong, so it wasn't any other failures, only something on the motherboard.

[GT-i9500] BOOTLOOP!

Hello
This is my first post here and I'd really appreciate advice in this matter.
I've spent the past couple of hours searching for an answer but nothing works or totally irrelevant results.
I have a problem where I'd rooted my phone with KingRoot, changed it to SuperSU successfully (restarted my phone several times since then and no issues)
I installed TWRP (only the app) from the Google Play store and that's as far as I got before I powered off my phone to cool down before attempting any installation of TWRP. Powered on my phone and I can't get past the Samsung logo.
Recovery won't come up, Download mode works but restarts itself and volume buttons do nothing to let me confirm download mode and so it's sending me in a loop. Samsung logo and restart again and again. I insert my battery and the first thing that happens is my phone goes on a mission, determined to power itself on only to Bootloop.
No, before anyone suggests it be a hardware issue, it's a brand new phone. There's nothing wrong with the buttons.
If anyone is going to point out the obvious in saying that I'm responsible for rooting my device, I'm aware of this. The rooting procedure was a one-click method which was successful and caused no boot issues after restarting the phone countless times.
Basically:
Bootloop
Can't access recovery
Can't get to Download mode without it getting back into the bootloop after 5 seconds or so. Volume buttons do nothing to confirm download mode.
USB debugging wasn't enabled before this Bootloop occurred
Do I have a paperweight or is there a way to salvage something from this?

The phone isn't supposed to power itself on after inserting the battery.
This behavior is only acceptable when the phone is plugged in while inserting the battery. But even so, the phone wouldn't try to boot up, it would just display the charging animation.

i had a similar problem where my phone would boot up to the white samsung logo as soon as i insert my battery. tirned out the power button was stuck. try gently knocking the power button onto the corner of a table or something with the battery pulled out. it might work for you if your problem is what i think it is.

Thank you for your response but would you like a video to prove that it is in fact attempting to boot up when inserting the battery?

I tested it on my device (I9505) and it doesn't boot up, it just turns on to display the charging animation. If I want it to boot up I have to hold the power button.
So, in conclusion, it must be your power button.
You can say the phone is new as much as you want, but there is a chance it came with a factory defect.
There might also be a possibility it is refurbished phone, which means it is pseudo-new.
