This might make you uncomfortable but turn on the screen and attempt to flex the tablet. See if this triggers touch recognition. (Enable show touches in Developer Options to help show this.) I myself have personal experience with the tablet triggering recognition when that happens.

Alternatively, if you haven't updated the tablet to the latest software version, do so. The shipping firmware versions have a serious touch sensitivity problem and newer versions have fixed it.

I'm sure you know this, but pressing the wrench&screwdriver icon/top clock section of the notification shade will open some quick settings (a WiFi shortcut, brightness slider, etc.), but other than third party apps that offer notification settings toggles, you can't directly customize the notification menu (like on ASUS' customizations of Android).

This is still speculation, but it's said the XPERIA Tablet Z's MicroUSB port has a hard limitation to 500mAh and that you need the SGPDS5 charging cradle to deliver more than that. I do find mine charges in something around 4 hours with said cradle.

I can't help on the keyboard issue. I use the default PObox Japanese XPERIA keyboard.

I enabled 'Show Touches' a couple of days ago to see what it was doing. So, I have just twisted the tablet as suggested, and yes, did get a couple of touches.

Also updated to the latest on Saturday just gone. Now running build 10.1.1.A.1.307 Android 4.1.2. It still does it occasionally. Perhaps not as much. Do I need to call Sony about this?

I downloaded 'Notification Toggle' This does almost exactly what I wanted.Just missing the Brightness slider, but the multi toggle works great.
[Xperia Tablet Z Q&A, Help & Troubleshooting] Hagar76:
If the MicroUSB has a hard limitation of 500mAh, how would using a dock increase this? No external device can overcome a hardware limitation.

I should think its more than 500mAh. At that rate it would take well over 12 hours to charge the 6000mAh battery.

I have ordered a USB current/voltage meter so I will do some testing with various chargers and device states and report on this forum.
[Xperia Tablet Z Q&A, Help & Troubleshooting] Cat McGowan:
The dock does not use the USB port to charge the tablet's battery; instead, it uses the charging points located on the lower left side of the tablet. The charging points allow for a higher charging ampere value.
[Xperia Tablet Z Q&A, Help & Troubleshooting] Hagar76:
Oh Very cool.

I wonder if there will be other non-Sony devices/attachments that will utilise these. I wonder if I could retro something :cool:
[Xperia Tablet Z Q&A, Help & Troubleshooting] juanyunis:
I've been using my Galaxy S4 ATT charger with my Tablet Z and it works perfect, my tablet charges very fast, looks like it's using 2A, so maybe the hardware limitation doesn't exist. I've the SGP311.

[Sony Ericsson Xperia Neo, Pro] rahulsai2341:
Installing pc companion or update service installs drivers for your phone..

Also try different ports..

If still not recognised go to device manager in control panel and mess with it.. U will it for sure..

i wanted to switch to other stock rom without deleted my music & pictures on my internal SD. i then was told i could use Superwipe for flashing a new rom without deleting anything from my sd. after i flashed superwipe i then flashed my new rom & as soon as the rom booted up there was no signal being foung on my device, & continuous reboots.

how can i fix this this and flash a functional rom?!?!?!?!?!? im currently in recovery mode
[Sprint HTC One (M7)] BrianBaker:

[Sprint HTC One (M7)] Konfuzion:
Sounds like whatever Rom you downloaded you either got a bad download or a bad flash, download the Rom again use superwipe and reflash.
[Sprint HTC One (M7)] cburch85:
If that doesn't work, then as a last resort use the Sprint RUU. everything will be fixed.

I was using my tablet while finishing charging. I was about 95%. Suddenly it just went black and won't turn back on. Any ideas? I've tried holding the power button with no results. Is there a special reset or something?

Anyone else have this issue or things I can try to fix it?
[Xperia Tablet Z Q&A, Help & Troubleshooting] juanyunis:
Have you tried PC Companion? Download it for Windows then try to locate for emergency repair. It will show you instructions of how to put your tablet in flash mode.
[Xperia Tablet Z Q&A, Help & Troubleshooting] Sean09:
I haven't tried that specifically, but would it not fail if the light didn't even go on when plugged in, and my pc doesn't even read it as connected?
[Xperia Tablet Z Q&A, Help & Troubleshooting] juanyunis:
Not really, for example in some samsung devices even if the device wont turn on the a JIG plug was able to put the phone on download mode, something very similar to flash mode on the xperia mobiles.

So i guess the last thing you can try is to put the tablet in flash mode, you can download a FTF file with the firmware compatible with your device, and download flashtool from: Click here to download and then put your tablet on flash mode. I guess you will need first the drivers Click here to see drivers and after you install the drivers, just open flash tool press the vol down key and connect the usb cable to the tablet, and if you see that flashtool or maybe windows recognizes your tablet you may have luck to restore it.

So if you get it into flash mode, then just flash the FTF and let's see what happens.

Let me know.
[Xperia Tablet Z Q&A, Help & Troubleshooting] Sean09:
I will give it a test this evening or tomorrow - thanks! I will post back if it works.
[Xperia Tablet Z Q&A, Help & Troubleshooting] Sean09:
PC Companion doesn't detect the tablet, nor does my PC at all in device manager. It doesn't respond like anything is plugged in, but it did before.

Flashtool comes up with nothing either - once again doesn't even acknowledge anything is plugged in.

Thanks for the suggestions, though.
[Xperia Tablet Z Q&A, Help & Troubleshooting] vjawsm:
hard reset is the only option... press vol up key plus power button...

just happened to me not five minutes ago.
[Xperia Tablet Z Q&A, Help & Troubleshooting] Sean09:
I read your issue. Read my first post again - yours is simply a crash. Mine does not charge, has no power LED, and is completely unresponsive. No recovery button combination or anything works - yours turns on and responds to things.
[Xperia Tablet Z Q&A, Help & Troubleshooting] andymg350:
so when you try vol up and power button do you not see the white led flash once then a couple seconds later three times? if it does it means your tablet can still be put into flash mode with some perseverance.

Edit: you could try sony mobiles flash tool called Emma which has its own way of entering flash mode (think you hold vol down and plug the usb cable in the computer) and see if that program can detect your tablet but you can use the instructions provided on their website if your unsure what to do.
[Xperia Tablet Z Q&A, Help & Troubleshooting] daurstyled:
same sitation

I have the same problem with my tablet. I watched stock photos in album and then display switched off. And that's the end.

Nothing happens when I try to power on, reboot or restore with Companion. Computer doesn' detect device. The same situation with Emma and flashtool.

I want to comment that I really think that a version of CyanogenMod 10, is not necessary because more or less Ice Cream Sandwich (CyanogenMod 9 and CyanogenMod 9.1) is quite useful. Also bugs that now exist, it is likely to appear in later versions. Or even more bugs.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] galaxys3world:
My AT&T Galaxy S3 has a charging problem. I have never had this problem before with other Custom ROMS or stock S3 firmware running JB 4.1.1 or ICS. I am currently running JellyBAM ROM V7.7.0. This is the ROM where the problem occurred. My phone charges very slow with the Samsung charger the S3 came with. So I used another charger and BOOM! It charges perfectly fine and normal. But now I have this problem. In order to charge it I have to twist and turn the charger when in the S3, constantly pull it out of the S3, put it back in, until I get a red LED and it says my S3 is charging. Literally the charger will be plugged in and it won't charge at all unless I push the charger in harder or pull it out, put it back in, twist turn, whatever. I have wiped data, dalvik cache, cache, factory reset, reflashed the ROM, disabled USB debugging, wiped BatteryStats, you name it. Nothing has helped. I have tried numerous other chargers, no fix, same problem. The funny thing is the stock charger the S3 came with, once put in, it's recognized, there's a red LED, and it says charging. But it is very slow with the stock charger. It will take about 10 hours to get to 100% from 0%. With the other charger it will take the normal 1 hour and a half, or two hours but it has this annoying problem. I do not think it's a hardware problem, because the stock charger has no problem being recognized or charging, it just charges very slow.

-I would really appreciate any help, thank you guys very much!

Hey all,

I have a CWM backup of my current rom and have backups of apps and data but am stuck at a bootloop.

As I have read countless articles, it seems my error is because I have a locked bootloader(not actually sure). Though, I only tried to flash

clockcycle's wiped v20d cwm backup file. It failed part way saying it couldn't write to /system.

Since then, I haven't been able to fully enter CWM. just see the red triangle with the droid guy on his back.

I have read Cmahendra's unbricking guide but it doesn't work as I have installed JB and even the tips to unplug, wait 10s and reopen the program to flash again it still won't work. Still stops at 15% saying error connecting to the phone.

There is a similar thread which had this exact problem which said to

use the online method to recover your phone since I had already installed JB. I edited the hosts file to remove the fake offline server and opened up the b2CAppsetup.exe, clicked on customer support,

entered my model LGP769BK and my S/N and it began to start the process and 'analyze' then crashed and said "updating is not possible any longer due to a fatal error while the LG mobile phone software Update"

I've tried to search this out myself and not waste any space but I'm at loss here. If anyone has any help, it would be much appreciated

as I don't have a phone while this is not working.

I've tried all the ways to to hard reset, master reset and still I get the droid guy on his back. I can get to S/w mode like all the other posts say to do but none of those fixes seem to work for me. Am I missing something?

Do I have any options here? I have kind of read that I should just unlock the bootloader but I don't think that applies in my case as I can't turn on my phone fully.

edit: for the online method(LG support tool), it basically cancels when it goes to the 'downloading' phase --> this is what I've seen as most of the answers but doesn't work
[LG Optimus L9 P760, P765, P768, P769] shockah486:
Upon further reading,

many seemed to need to replace their u-boot and x-loader

I did so and installed fastboot using Lelus' script here:

http://xdaforums.com/showpost.php?p=41768774&postcount=1

I used option 6 which allowed me to flash the u-boot and x-loader from p760(works with my 769 and others as it says in the options) for JB

I'm not sure if I needed this as I don't have an unlocked bootloader.

I'm not sure of commands in fastboot but I ran

fastboot devices and it showed something

I also ran: fastboot flash recovery recovery.img

and I put one of my cwm backups in the "yours" folder

After I activate fastboot, it brings me to the C:\fastboot\yours folder

I assume this is for me to put my intended files in but I'm unsure if I should use my cwm backup or something else?

After it flashed the recovery img, I sent a fastboot reboot command

but it still went back to the droid lying down with a red triangle.

As some of you may see, I'm not too great with this but I feel like I'm close. Does anybody have an idea of what I should be doing?

should I flash an update.zip?

I don't know many commands but hopefully this gets me going in the right direction.

PLEASE HELP ME!!!!
[LG Optimus L9 P760, P765, P768, P769] dhruvbatra205:
I guess your cmw restore formatted your system but couldnt load the new system

the recovery you run with a locked bootloader uses a technique called 2nd init which i think is somewhere stored in the system partition. so when the recovery formatted the system, it lost itself too.

I've had a similar problem. the way out would be booting into the SW upgrade mode--switch off the device, remove the battery, remove the usb cable. press the volume up button and connect the phone to the computer. wait for a couple of seconds and then insert the battery.

you should be in the SW upgrade mode

now use the B2C client. if it gives an option to upgrade, use that otherwise, go to the customer support menu and press recovery phone
[LG Optimus L9 P760, P765, P768, P769] shockah486:
I have already done earlier. It may have gotten lost in my frenzy of information. I have put the phone into software mode, as you said, and it won't work either; There's no option to click upgrade because it's JB(V20D) and when I click recovery phone and enter my imei, LG mobile support tool(B2capp.exe) analyzes and then has a 'fatal error'

Since I flashed the new u-boot and x-loader my screens are all backwards/mirrored. Maybe the tool flashed an unlocked u-boot and x-loader if that's possible.

Is a recovery possible by fastboot?

I have a clean and full copy of my cwm recovery as well as apps and data backed up, I just need to get this phone in working order
[LG Optimus L9 P760, P765, P768, P769] Tablechair:
If you fastboot flash the u-boot and x-loader from p769(ICS) it should go thru with the offline flash detailed in cmahendras guide.

Use the KDZ_FW_UPD.zip from this thread

Or try this

Remove all of the stuff you have downloaded for this. Download the original B2C client from LG's site and use that
[LG Optimus L9 P760, P765, P768, P769] shockah486:
Thanks.I'll try this. if I have the ICS bootloader, does that mean I'll have to flash the V10G kdz? or can i do the v20d kdz

I have the updated kdz fw upd .zip from the unbrick and root thread as well as downloaded a new, official B2C client but they all still hang at the download part during phone recovery.
[LG Optimus L9 P760, P765, P768, P769] shockah486:
Tablechair, that did the trick.

Is this because the tool we use to flash for the offline method doesn't recognize the x and u-boot loaderse of JB?

After I installed the ICS boot loaders, my software upgrade mode wasn't mirrored anymore.

I did as tablechair and flashed the V20D.

Does anyone understand why this problem happened in the firstplace? Maybe I didn't get a full copy of clockcycle's backup cwm

or should I have not flashed his recovery in the first place since I didn't have an unlocked bootloader?

Again thank you for all your help and if anyone can provide answers to my other supplemental questions, that'd be great.

Off to root and probably unlock bootloader to be sure.

edit: I can't find the thanks button. but thank you very much tablechair. much appreciated. Hope this can help someone else

p.s. also big thanks to those who made the fastboot program for p769(Artas182x and sguerrini97). really an invaluable tool as I now know.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Things don't always go according to plan, maybe his Clockworkmod backup was made from the touch version and he didn't have artas182x second init recovery installed. So when the cwm failed the first time, did you try to restore your cwm backup?
[LG Optimus L9 P760, P765, P768, P769] shockah486:
Not yet. having problems flashing a kdz again. I've tried the 2 different software modes, as well as setting emerg and diag but still getting stuck at 15% again.

Do i have to replace my uboot and xloader with the ICS ones every time I want to use the offline flash method?

edit: yup, after replacing with ICS loaders again i'm able to flash using software upgrade. will update on whether I can restore cwm
[LG Optimus L9 P760, P765, P768, P769] shockah486:
I realized I misread your question. When I flashed before the incident, it failed to write to system and I didn't restore my other folder. I rebooted and it was all missed up. Anyway, now that I've got everything back and now with an unlocked bootloader, i was able to recover my old image. However, data isn't working so I have to find the radio to flash as I recall reading in other threads.

Can someone explain in laymen terms why this is? recap, i was on unlocked bl rooted jb and I flashed my old cwm backup when I was rooted but had a locked bl. My apps and messages were all there but the radio was different. I'd understand if I was going from ICS to JB but I was on JB both times. The only difference being a locked BL. It's got to be something about the Radio from p760 or V20B that didn't work on my earlier backup or something like that because the layout status bar is different with a "data" button and showing H instead of 4g(which are the same afaik).

Since, I restored to my backup from after my bootloader unlock and root so data is working showing 'H' with the different layout

Also, I had problems backing up and restoring until I noticed that it works better when I power off the phone and do the manual commands to enter recovery as opposed to using the app to send me to recovery(where I incurred /system backup errors).

My last question is which cwm recovery should I use? I currently have the one for a locked bootloader installed as per Artas182x's website. On that post he has a link for an unlocked bootloader recovery on the xda forums but that thread was updated to not working. Are there any disadvantages to me using a locked bootloader cwm recovery?

I don't think I have any option but to try it as I want to flash CM10.1 for p769. I also read that if your bootloader is unlocked, you can download the cwm from the googleplay. If this is true, can I just install over or should I uninstall the Artas182x locked bootloader one????

update: have to remove l9 recovery by deleting the appropriate system folders and then flash the appropriate .img through adb commands
