[Q] Bricked NO power whatsoever - Xperia Z2 Tablet Q&A, Help & Troubleshooting

Accidentally borked this trying to repair. Accidentally flashed wrong thing and went into boot loop. Since then it has stopped turning on and off, no hard reset, no nothing. I dunno what to do. I can't flash anything new since it has no power even though it's very charged. It doesn't respond whatsoever. Can anyone help or am I screwed?

just to add the haptic feedback that indicates the device is working doesn't work either. there's no way to get it into fastboot mode to reset as it wont turn on. Please help. I've tried to flash .ftf but wont work because it wont turn on.

Perhaps you should read this thread to get some ideas.

I have my share of bootloops and find this thread quite useful. If your problem is that your device won´t charge, have you try to charge it with dock?

I have the latter...it wont boot at all and no 'bump' or anything like that. it doesn't do what you're saying it should be doing to recover. I will try the red button but so far nothing seems to help. thanks for the advice I was going to send it to sony but sounds like ill void my warranty. just to be clear when i push the power the things that it usually does don't happen. no haptic feedback, no 'bump', no nothing when you push the button. Its on charger so the issue isn't battery. it just doesn't charge AFAIK. or can tell. Well, off to the red button and see how that works. All I have yet to try i believe as i cant use the other tools till it turns on at least.

the soft brick red button didn't work as it just presses down. Im still stuck without power and without a way to reinstall software. or get rid of brick. any other suggestions before i send to sony?

any ideas before I send to sony? they probably are going to void my warranty. the red button only goes up and down. it wont' stay down. and it doesnt work at all. should i just send it in and hope for the best?

I had this the other day, flashed the wrong thing, spent hours looking over the net, no haptic feedback, no light when connected to the charger, no fastboot, it seemed dead in every sense of the word, requested an RMA from amazon, I had til the 12 Nov to return it, since I was going to Italy for for 12 days I thought I would take with me, if I couldn't sort it I would return it as defective, night before I was due to leave, tried the power button and it jumped to life, as if nothing had happened, flashed the correct image and here I am in Italy writing this on my Z2 tablet, not sure if it helped but I had mine connected to the power 85% of the time I thought it was dead

The onlynresson the RMA worked was the unit not responding otherwise my warranty was void. Turned into a positive as they replaced the unit. I left it charging for a week with no change. Good for you though.

[Q] Bircked my Folio?

Ok, a bit akward. I think i bricked my folio 100. I was working on upgrading to honycomb, i did some things wrong i think. Problem is now when i boot the screen stays black and only the power led goes on. Any idea where i shuld search to try and get it back to live?
if you can boot into fastboot you might be able to save your devise by pushing the revovery and rom to ur devise

Did you try to connect to fastboot? Maybe your screen is broken (or if you are lucky the screen connector is loose). Does it vibrate when you turn it on?
It is very improbable to brick this device by flashing something. At least I never heard of it. Only thing known to me to fully brick your folio is by pressing 4x Power and volume down on boot (don't try that...).
When i press the power button it does nothing, only the power led on the right turns green (white when on AC ).
Also, when i connect it to usb and do a fastboot devices i get no respons. Realy think i did something wrong and bricked it :S

I brick my Folio too, and now it don't have logo when power on.
I tried to get battery off and press the reset on the back, and nothing happened.

apologize for interfering & oftop, but certainly cant keep silence - "impossible to brick" - same i was told abt my dell streak device, but here I'm with bricked device on hands, where only ORT-JTAG can help :-(
it was bricked when PC hanged during rom flashing....so I guess every chance is possible :-(
Shidima_101 can you describe in detail before/during brick ?
Well, I'm not really sure what i did. And i think that is the problem. I was installing a new rom, and left it unattended. When I came back, something was wrong and I started messing with some options. Witch turned out to be wrong i guess
Tho I'm a little further now. When I connect the tablet I my pc recognizes its there a device, but I'm not sure I can get it working again. Tomorrow I have some time to look at it more.
Sader0 can you give me some info on ORT-JTAG? Do you know if its possible to do this on the Folio100 ? I don't mind opening up the tablet to get it back in to working order.
I'm in the same situation.
After the update to the last version, my folio apparently boot but the screen is blank. The backlight is on but nothing appears on the screen.
I'm able to go in Fastboot or in recovery mode, but formatting cache. system and reflashing different roms do not solve the issue
What I should do ?
SOLVED !

Not sure if I can even get to fastboot, but ill give it a try tomorrow. Im at my work now and didnt bring the tablet
bricked
I ****ed up? 4x power button, Ar there solutions?
gtrz
Ok, I have a small update. After trying a lot of different stuff, and nothing working, I decided to bring my tablet back to the store. First I tried to get them to switch my device for a new one, but that was a no go. So the device was returned to Toshiba for a check up and fix.
I was a little afraid that they would find out that i rooted and bricked my device, but today I got a letter telling me I can come pick it up and it was fixed free of charge
So tomorrow I'm going back to pick up my tablet

Encryption Unsucessful - Prime Bricked Itself

I've had this thing for a good month or two and its ran like a champ. Never had issues really. Never Rooted, its basically stock and its been nothing but great to me.
This brings me to this evening. I decided to record my 2 year old dance and really havnt used the camcorder before. Gave it a go, recorded him, and as soon as I hit the STOP button on the camcorder, the tablet basically froze on me. Couldn't do **** for whatever reason.
So I figured ok, I'll shutdown by holding the power button. As soon as I fired it back up, I get a Encryption Unsuccessful message. It basically tells me my data is corrupt, can't be restored unless I do a factory reset. It gives me a button to reset and I push it.
It basically reboots and comes back to the same dam screen. I have no idea what the hell to do. I'm so screwed....
press and hold volume down and power. When the tablet reboots, keep holding both buttons until you see writing in upper left corner of boot screen, let go of buttons. Now press volume down and it should bring you to a menu with some options. Press volume down( I believe) to select factory reset/wipe date, then press volume up to select it.
If this doesn't work, and your boot loader is still locked, try to manually update the tablet(put factory Asus update on external SD). If that don't work, you may be screwed.
Its fixable with an unlocked boot loader.
I can try to help you. But first, lets document some things.
Where you on the latest version of ICS? (.15)
What were you doing when this happened: Already stated that
Do you have an SD card in your Prime:
Also, let's accept right now your data is lost, and is most likely not recoverable. Basically, this screwed up the /data and /sdcard folder. If you RMA the Prime, you will most likely get a new device, as it is not bricked, but beyond software fixing it. Someone please tell me I'm wrong, but I have gotten this before, I had no way of recovering, and had to get a new Galaxy Nexus.
But try these steps:
Turn the Prime off. Hold down both the Power and Volume Down.
Once you see text in the top cornor of the screen, press volume down.
Select Factory Data Rest, and hit the Volume Up confirm the change.
Let me know if that works.
Good luck!
I was still on the .13 build. I dont have an SD card either. Like I said, this **** happened outta nowhere and I'm dumbfounded right now.
Please tell me I don't have to F'in factory reset and wipe? UGH!

Losing all your data right now, unfortunately, is the least of your worries. This is also something that needs to be reported to ASUS ASAP.
If you are getting to a screen, you are most definitely NOT bricked. If you see a light on, if you plug it on and the light comes on...you are not bricked.
Try the steps mentioned to get you into the menu where you manually select the options.
Good luck

Oh yea, least of your worries for sure. Hopefully most of your important stuff syncs to the cloud or you have a recent backup. Resetting your personal settings, screens, etc will be a huge relief when/if you get it up and going.

I know what you mean..lol hate having to set everything up again. but its needed though to bring back your tablet. once it gets back to normal I'd suggest updating to latest update .15. has most of old bugs fixed and more stable. plus you might get an updated camera firmware also.
good luck n post back how things went.
Well I would love to try all these steps guys, but now the F**cker wont turn on. Just vibrates. Tried plugging the charger in, same thing. Wont even turn on.... !

try plugging your prime up to t.v. through HDMI connection. see if prime might actually still be on but the screen is off. if you can see prime screen then if it lets you, try a factory reset that way by going into settings then backup/factory reset.

Well I wouldn't be able to go to settings and factory reset, because I can't get into ICS...we've established that. When I get home, I'll try my hdmi cable I guess.

that was when your prime was on and you could see the screen. could be possible the reboots stopped but now the screen doesn't want to come on..worth a shot.
No matter what screen your prime is on, whether the prime is turned off or on, press and hold volume down and power. What does that do? Keep holding it until something happens.
Tried the HDMI cable, nothing came up either.
When I hold down volume and power, it vibrates after about 8-10 seconds. Then nothing. I havn't held it down much longer than that.
tried holding it down for a minute after that...still black screen.
How does a friggin tablet BRICK itself, STOCK? Please enlighten me!
Guess I'll leave it on the charger all night just for hells sake
I've seen this situation here before. your best bet might be to keep doing what you doing to make it vibrate and drain the battery somehow. once its dead or doesn't vibrate anymore, let it charge up till the led light is green at full capacity. then try cutting it on. that has worked for a few members who seemed tl have same issue as you.
The led light doesn't come on tho at all when plugged in. Should it? Or only when it's fully charged?
it should at least be on and be a red color to indicate it's charging. a green color to indicate its fully charged.
is it still vibrating when you attempt to put it in recovery mode? if not then the power might be drained already. sometimes when battery is really dead, indicator light will not cut on until it has a decent enough charge. like some people who received their prime couldn't get it to cut on even plugged up. their battery was that dead and needed to charge for a while before it finally cut on.
constantly rebooting tablet does drain battery. maybe you already drained it, especially if it no longer vibrates anymore.
Naw it still vibrates just no led indication whatsoever. Holding down the power button only makes it vibrate and that's it, no display. I coulda swore I had like 50 percent right before I used my camcorder...weird.
I'll let it sit on a charge for a bit and see what happens. If I get this fired up I need to decide on rmaing it or not. Argh.
Thanks for the help....and to all...

no problem. it might be best just to RMA it anyways. so you won't have to deal with the risk of this happening again. plus chances are good they will send a replacement unit if they can't fix it. good luck!

No big deal, you were just out of battery and your charger is not working. Put you charger in a freezer for 2 hours and recharge your ATP 2 hours with It. problem will be solved after that.

my phone won't turn on!

i've had the phone for about 7 days and everything was fine until tonight when i tried to use my phone. the phone won't power on anymore.
i plugged it in for a couple of hours and it still didn't turn on. the battery wasn't low when it died. i also tried holding the volume down button then powering on. I even tried plugging it into the usb. i don't know what else to do.:crying:
is it rooted or unlocked? if so which freegee is it unlocked with? you could always join the irc channel for some help. it may be faster through that

My brother actually has a completely stock one and is complaining if the same problem to me. I just told him to return it for a new one. Mine is rooted + unlocked and not suffering from any problems. Possibly a hardware problem or overheating?
My friend just had the same issue this morning,
the phone was very hot and wouldn't turn on.
we tried pressing pwr+voldown and nothing happened. then tried pwr+volup and it then showed the LG log but as soon as we let go of any of the button the logo disappears and nothing else happens.
charging also didn't help
*his phone is un-rooted. So i told him to contact Rogers wireless.

Sounds like a soft brick. Happened to me a few times. Tell him not to worry. LGNPST would fix this.
Edit: didn't see that it was unrooted. Yeah I think you told him the right thing. That shouldn't happen if he hasn't done anything to his phone.
I have had this happen several times.
If you press (or hold) the power button, do you see a cheap white "battery charging" animation?
I can't say exactly what, or why, it works, but keep at it. I think the magic trick is to hold the power until the LG logo has appeared and the boot animation is about to (or has) started.
Sorry I can't be more specific, but I was panic stricken every time. If this is happening to you, then you understand what I mean.
I hope this helps someone. This phone seems to be full of issues... I'm just hoping the software it's the cause, and not the hardware.

Same problem for me, phones stops responding unexpectedly, could be that it's power-off by itself but in order to power-on it I need to press power button for a long time ~30 sec. I was thinking that it's because of SnowJB custom Rom but it seems not, the strange thing that it starts only few days ago and appeas almost every day. May be it's needed to format internal or external SD card to fix it?

[Q]My Sola doesn't boot up or charge

Yesterday I flashed a custom ROM and the phone worked properly without any problems, Next day when I woke up the phone wasn't on so I figured it needs to be charged, But when I plug in the charger the LED gives the Orange light for a split second and that's it I don't even know if it's charging.
I tried to restart it with power button + volume up combination but still nothing,I left it plugged in for about 3 hours and still nothing.
I've read Posts describing the same problem and the guy got a replacement unit, I want to ask about the custom ROM I installed, would it void the warranty, I haven't unlocked the boot loader, I just rooted it and installed a recovery to flash the ROM, Would they even notice?
I just want to confirm if I had voided my warranty.
Thanks in advance!

The problem is Force shutdown doesn't work, I searched for a solution but it was no good, I found a thread with similar Problem but the guy got a replacement unit, So I thought I can get it fixed or replaced at the service center, But I'm worried about the warranty, You see, I flashed a custom ROM, So I don't know whether my warranty has been voided or not, If any one here has encountered such problem help would be much appreciated!
Here is the thread i am referring to, I have the exact same problem but this guys phone went completely dead, Mine is still giving me the LED Orange Light when I plug the charger, but for really just a split second, not even one second literally.
When I hold the power button nothing happens, and when I try to force shutdown nothing happens, no response at all.

I tried that too, when I got really desperate I just made up combinations and tried it to see if something might work, I can only guess that this is what they call a brick, right?
Anyway I sent the phone to the service center today, I don't know what's gonna happen, I just hope they fix it for me, I bought it just 2 weeks ago
I'll post the details about if it got fixed or not and what the problem was for future reference to this kind of problem
Thank you for your concern guys, I really appreciate it!

[Q] Failed FTF flash, any way to unbrick my Z2 tablet?

Hey XDA,
tried to flash the 17.1.1.A.0.402 FTF on my unlocked SGP511 Z2 tablet and something must've gone terribly wrong. Flashing seemed successful, but it won't switch on anymore, I can't enter Fastboot mode, I can't enter Flashmode and the recharge LED isn't on anymore when I connect it to the charger.
This is the first time something like that happened to me, I had several Nexus devices (and two G1s) before, flashed custom ROMs countless times, but I never managed to get one of them into a state of complete unresponsiveness.
Is there any way to unbrick my tablet?
EDIT: just to clear that up, holding Volume up and power doesn't do anything, so does holding Volume down while connecting it to the PC.
Almost Same problem with me..
Cant get in to the OS no more after installing CWM

I've had a similar issues with bad flashes before.
Is it possible you flashed an LTE fw to a wifi only tablet?
I got round it by setting flashtool to be waiting for the device in flashmode (with the picture saying hold the back button and plug in) and then with the tablet repeatedly pressing the power and volume up, waiting for the reboot and quickly plugging in with the volume down until the device was recognised.
It appeared to me to be a timing issue ie. catching the plug before the OS started loading but after the device had started the reset mode.
I know you said the power + vol up doesn't respond for you, this may be due to the battery draining so much that it simply cannot power up anymore. I would suggest plugging it into the wall (not a usb port of a PC) for a few hours first (even if the LED doesn't light up it doesn't hurt to try to trickle some power in and eliminate that from the possible causes).
Basically, keep trying flashtool and trying to reflash your ftf. It might help to redownload it too or double check the md5.
Also, I haven't tried it, but I read somewhere that the red switch under the SIM/SD flap is a hard reset button that does the same as the power + vol up.

Thanks a ton for the help, I definitely flashed the correct FTF, that was actually my second flash and it worked with the same files half an hour before. I also tried all combinations of Flashtool in flashmode, power/volume/power off button/USB cable I could think of repeatedly already, to non-avail.
I'm currently settling with the fact that I somehow managed to hard-brick my tablet and that I have to face the cost to send it in to Sony for repairs.
Most probably you didn't hard brick your tablet.
That is very difficult and unlikely.
Most probably you just didn't do the steps for reanimating the device right.
Hard reset (Vol Up + Power). Then, while holding Vol Down, plug in the USB cable which is connected to your PC. (Do you have the drivers for the tablet installed on the PC?) This should make the LED go blue. (=Flashmode.) Then you can flash a FTF (take the right one for your model!) with Flashtool (not the Sony one, but the xda one with the same name).

That is very difficult and unlikely.

Thanks a lot for your help, but unfortunately the tablet doesn't react to anything anymore. Before e.g. the LED lit up when the tablet was charging, that doesn't happen anymore. Hard Reset usually made the tablet vibrate, doesn't happen anymore, either. Same for Fastboot mode. Flashmode doesn't do anything to the LED and FlashTool doesn't recognize it anymore, too, when I boot it with Vol down pressed. I've done all that countless times over the past week and nothing works. I know that manufacturers make it pretty hard for their devices to hard-brick, but this time I'm completely at a loss, there's nothing I've not tried so far.

Thanks a ton for the help, I definitely flashed the correct FTF, that was actually my second flash and it worked with the same files half an hour before. I also tried all combinations of Flashtool in flashmode, power/volume/power off button/USB cable I could think of repeatedly already, to non-avail.
I'm currently settling with the fact that I somehow managed to hard-brick my tablet and that I have to face the cost to send it in to Sony for repairs.

After you feel you bicked it, was the device still vibrting when hard resetting? If it was and now ot isn't then you've probably just deadened the battery by asking. Iitt to repeatedly reboot.
Try leavingg. Itt plugged in to a wall forr a few hours and every oncee in a while try the hard reset again to see if it starts to respond.

Unfortunately I have tried that already, too. It doesn't seem to charge anymore (LED doesn't go on), no matter how long it's connected to the charger. I also tried charging it with a couple different chargers besides the original one already, that's also not the issue. It was completely unresponsive as soon as the FTF flash was finished.
Unless there's an "undocumented" alternative flash mode (JTAG pins? NAND chips exposed somewhere on the board? But how would you open the tablet, anyways?) there's nothing I can do. I've sent an Email to Sony mobile support already, I hope they'll answer with an andress where I can send it to, soon.
I yesterday overcame an issue where I couldn't enter flashmode by using PC Companion and using the repair software feature, but PC Companion needs to recognise your device first so I guess it is out of the question. Nonetheless, I think anything is worth a try.

No dice, unfortunately. :/
To add insult to injury Sony Mobile refuses to repair my device, at least the hotline guy told me so - even though I explicitly told him I'm willing to pay for it, since there's no warranty due to the unlocked bootloader. Anyone has any experience with that or knows whom to mail in such a case?

Unfortunately not.
You could try and PM some of the respected devs around here for advice on last resort recovery from bricking. DoomLoRD and maybe Jerpelea (aka FXP who now works for Sony) come to mind.

Thanks for all the help, I finally decided to sell the defective tablet at Ebay (correctly marking it, of course - I hope some repair shop buys it for parts) and bought me a new one. Owning two Z2 tablets right now, feels a bit strange.
Same happened to me today, nothing helped. Going to send it to Sony for repair

After reading over your posts, I think that was a good choice to sell on ebay. However, Patience in keeping it on a charger for many many days (i put an hp touchpad 3g with the same issue on for a week before it finally gave response) could have fixed it... A tablet with no response like yours usually will still get a trickle charge over time and in turn revokes a response. Hard bricking a tablet is always misconstrued when in reality it was a soft brick, even in your case.
Anyways good luck with the new one!
The same thing just happened to me last night. It's pretty ridiculous how it happened to. I originally got the tablet a few months ago and rooted it with CWM via Doomlords method. Was working fine for a while. No issues, not using it for anything in particular but regular media. I do believe I restarted the device a few times before this as well. So I was maybe going to start getting more into modding especially since CM11 finally has builds for the Z2. I powered the tablet down, tried to go into CWM recovery (just to make sure it was still there) by pressing volume and power buttons, the thing then just vibrated and flashed a couple different LED colors before dying. That was it, the thing was utterly dead. I've tried all kinds of combinations of the buttons, going into fastboot with a USB connected to the same PC I used to flash/recover it before, charged it for well over 8 hours. Nothing....
I'm a bit of a fighter though. I specifically remember a friends xperia z (phone) dying and showing no life and then just reviving with no noted fix. I'm going to try the constant charge method for a while. I'll likely update with any luck.
Edit: No progress, I called Sony and just played a little dumb. Will be sending it to them soon. I think I may have an actual hardware problem. This happened without any recent flashing/major changes and I can't even get any kind of signs of life in recovery.
Hello guys, same problem here.
Flashed my tablet with a .402 ftf file everything went well. I played with the tablet for 4 hours. After that I tried to flash it again, the flash was successful, I booted at least three times on the tablet. Then it just went off and now I have nothing. No LED when pluging to a wall, it's no recognized by my computer.
I was thinking about dismanteling it, unplug the battery and try to boot it on again. Has anyone tried to do this before?
Also if you have any clue to dismantle feel free to give it to me.
I'll keep you in touch

Sounds a bit like my symptoms. I also flashed a .402, first flash worked and booted perfectly fine, till I decided to flash it again, then everything went off and the whole unit was dead. Problem is, I don't remember flash tool displaying an error, but I also didn't look for one, that's why the only explanation I have is a faulty USB cable. Maybe it's a faulty image? Do you remember where you downloaded that .402 image?

Yes, I downloaded it here: http://forum.xda-developers.com/showthread.php?t=2765250
I'm 100% sure that the flash worked the first time with this image. I haven't modified the ftf file and when I tried to flash it again as I said it went off but not instantly. I was also working on the kernel when it crashed but I don't think I bricked it because it should do something: boot loop or at least the led turning red when plug-in it to a charger.
I bricked tablets before and I know the symptoms, but just having a dead device like this is totally new. And really anoying...
Sony just told me to return it to them.

Good for you, I hope they'll repair it. I wrote off my ~260 EUR loss already (broken tablet fetched 220 EUR on Ebay).
I'll have a look if that's the same image I flashed in my lunch break.

I don't think they'll repair it since I've unlocked the bootloader and rooted it :/ but anyway it's broken so it worth a try. If they return it to me I'll just try to dismantle it and see what's going on.
Good luck with your tablet :/
