Xperia Z C6603 LB Soft Brick? - Xperia Z Q&A, Help & Troubleshooting

Hi,
I have a problem with my Xperia Z. I can't start the device. I had this problem once before, and honestly I don't know what exactly I did, but it worked (I guess I connected new LCD, started device, then connected old LCD - it worked, so I glued on device and was using it. In the meantime I was flashing it 1000 times and doing whatever I read in web).
BUT when battery was 100% I decided to turn it of just to see if it will turn on (becasue I wanted to sell this phone, don't want any problems with selling not fully working phone) and gues what- it doesn't turn on....
Soft reset - vibrate working
Hard reset - 3x vibrate working
power on - vibrate working
flashmode - no problem
fastboot - no prolem
soft upgrade via PCC - no problem
soft upgrade via Flashtool- no problem
LED icon - working fine.
But it is just not turning on (LCD isn't showing anything, folder with files is not showing in computer).
Phone has locked (Unlock Bootloader Allowed:NO) bootloader so I'm rather limited. Warranty is of course not possible.
Looking forward to hear from you, hope you guys have any idea what to do.

partially solved- it is not software problem.
problem is with LCD - it is not possible to turn on the phone with this LCD (checked on second xperia z) but this weird LCD works normally when connected AFTER booting on with different LCD. Tested few times on 2 different c6603
Any ideas how is it possible ?

Your lcd broken

[HELP] Display glitches/black screen

Greetings,
I'm not experienced with android devices, so i thought i'd ask here first before trying to do anything.
Since a few months ago some weird things started happening to my X8 - random display glitches and blackouts at completely random intervals (sometimes one or even two a day, sometimes it can last two or more weeks w/o an incident, i haven't figured out any relation yet).
Glitches manifest in distorted view on screen - shifted up/down/sideways - or colored graphics artefacts - up to completely bizarre patterns of random-colored pixels covering the whole screen. Weirdly enough, pushing power button as if to lock the screen usually alleviates the issue, sometimes i need to do it few times to remove completely, but it works. Touchscreen works fine, but i need to tap the "right" spot on the screen, not where it's displayed on the screen ("right" as in where the element is when the screen is not glitching).
The other issue (may be related) i'm having with the phone is random screen "blackouts" - the screen goes completely black and the power button cycling doesn't help - but the phone still reacts to screen input (i.e. i can unlock the screen by dragging the slider, launch app, start/stop music playback and so on). I can see the backlight on, so it's definitely screen/gfx hardware issue, not backlight. If i try to reboot the phone, it hangs on either shutdown or boot up. Removing the battery, placing it back and booting the phone up doesn't help - it vibrates as usual, i see the backlight go up, but screen stays black and i can't interact with the phone even if i leave it there for a few minutes (which is more than enough for it to boot up - it usually takes ~30 seconds till full boot). Also the backlight won't go off. It usually helps to boot normally if i hit the phone with a palm on the back side and/or leave it alone for a while. This issue is much more rare (only had it three times), but it puts the phone out of service for a while, so it's an issue for me.
Now, the device info:
Sony Ericsson Xperia X8 E15i
015 baseband
10W44
Unlocked bootloader
Alfs8 kernel (2.6.29.6-Alfs v08a 24/03/2012)
GingerDX v026 ROM
No cpu tweaks done, cpu governor "ONDEMAND", cpu speeds 122-600.
The glitches started when i was still using the older version, GindgerDX v013 with locked bootloader, i have done factory reset and flashed a new version with new kernel (and unlocked the loader along the way), but apparently it did not help fix the issues.
I can't provide and screenshots/photos of the issue because the only camera i have access to at most times when it happens is my phone one and, obviously, i can't use that in this case
The question is: can i still try to fix it by myself (i can do it if it doesn't involve disassembling the phone completely - i don't have the screwdrivers required) by software tweaks or other techniques or should i reflash stock kernel/rom, apply for warranty and hope they find the defect and fix it? I really do like the phone. Or, maybe, you have encountered anything resembling these issues and may shed some light on what's happening.
Appreciate any input in trying to figure out and fix this.
Thank you if you have read all this even if you can't help me, cheers!
1st problem could be 'Screen Cut' issue which is solved using kernel without FPS Cap...
2nd problem usually happens on my phone with miniCM9 3.0.2 but shows splash and boot animation...
Can you see the splash screen and the bootanimation? Because my friends' Xperia Ray has the issue on official firmware... so it could be hardware damage...
Try unlocking the screen then press the power button then press it again...
and also try flashing the stock firmware... If it doesn't work... I think you should live with it...
Sounds like a hardware problem to me. Reflash stock kernel and ROM and full wipe and then flash a different ROM and see it it still happens. If it does I think it is advisable to send it to Sony for repair.

Thanks for your replies, i'll try reflashing the stock rom and see if it still happens.
@Lily48: no, no splashcreen or boot animation, just black screen and visible backlight.
I have the same problem and I checked it many times and my conclusion is....ITS A HARDWARE PROBLEM NOT SOFTWARE..

Well, notify me if you find a solution, thanks
Sorry for double post, but this is important update:
My phone died this morning with the permanent black screen syndrome. Until i rebooted i could use it to receive phone calls or even listen to music (i knew where to touch to activate the features). However it would not boot sompletely after restart, even if i leave it for ~hour. Connecting to flashtool showed that it does boot to a certain stage, but no GUI (for user interaction with haptic feedback) available - the flashtool does show that device connected with usb debugging enabled.
I reflashed the stock ROM, now it's apparently stuck in some sort of bootloop - it keeps on connecting and disconnecting. But the screen is still black, with backlight. If i remove the battery, replace it and just connect to pc w/o trying to boot on, it acts normally as if trying to charge - backlight activates for a few seconds if i touch a key and green led is lit, but still the screen is black.
I will RMA it tomorrow, thanks for help, hopefully i'll get a new one, or they'll repair this one so it does not glitch on me again. Anyway it was/is a good phone, i absolutely love it.
Wish me luck =]

It is a hardware problem and Sony Service Center is the last option you have.. if your X8 is in warranty period.
I did the same and they replaced its display with new one.
Hello, reporting back in:
Just got my X8 back, it really was a hardware problem. They changed the screen now it works as good as new =]
Thanks everyone for support

[Q] Xperia Z Screen just wouldn't want to Turn ON anymore

Hi Guys
Got this phone on the 27th Feb, and It has already giving me problems.
Just want to share and hope somebody has a solution.
BTW, my phone has not been rooted nor boot unlocked YET. (Thank god for that, else I might have problems if I want to send it back to Sony)
Problem: My Xperia Z screen does not seem to want to turn on. The phone state itself is ON, as I can hear phone ringing or when notifications received, But the screen stays OFF the whole time.
How it happened: Was playing a game when I believe a call comes in, and *Poof*! The screen goes dark.
Already tried:
- Hard Resetting the phone (Power + Vol Up + Vol Down)
- Have also restored the phone using Sony PC companion software. Phone is now back to original settings.
But THE SCREEN IS STILL BLACK AS NIGHT throughout the resetting and restoring!!!
Can somebody please help me out.
Warranty exchange I think...

This happened to me today. I thought it was a dead battery so I plugged it in to charge, hard resetted the phone, it displayed the battery logo and then it booted. It was 29%. I don't know why it was unresponsive.
My phone encountered the "sleep of death" twice.
It does not ring, but when you call it, there is a ringing tone.
The only way to revive is to press VolUp + Power. That will cause the phone to bootup/restart.
Not unlocked nor rooted also. Kinda worrying..

Phone wont boot (only while USB is connected)

I'm having the weirdest problem.
My Xperia Z wont boot up, it will only boot when i have USB in my PC and connected to the Xperia Z.
When I disconnect the USB the phone shuts down in about 3-15 seconds.
I tried to reflash the stock tft via Flashtool.
I tried to reflash via SUS
I tried to reflash/repair via PC Companion.
At the moment stock firmware is installed but the problem is still there.
I tried to Google but I cant find anyone with the same problem.
Please help!
What's your battery like because to me is sound like a battery problem, USB is supplying power and a soon as you remove power it dies,
Boot phone up and do a service test on battery *#*#service#*#*
A maybe completely wrong
P. S. Have you had your phone near water what colour is the paper under your tabs (should be white not pink)

I have the exact same problem! have you found a solution yet? i'm thinking it's a hardware problem because of the fact that i have had this problem on different ROMs and even when i flashed it back to original firmware using sony's flastool.
The battery test under *#*#service#*#* says there's nothing wrong with it...
It's getting really frustrating actually... Phone is practically unuseable...
i think your phone does not turns off, im having the exact same problem, try put the screen to sleep every 30 minutes, if it last 30 minutes with the screen on, then your phone is having the same problem i have:
something like the volume up button "always pressed" so the power button doesnt react because its like detecting hard reset combination.
if the screen sleeps, you press the power button it does not come up, if you connect the usb, screen comes up. phone is not off.
if its like that, im glad i helped at least identify the problem (if you find a solution other than sending to sony (they'll charge me because my warranty is void) PLEASE TELL ME
EDIT: I FIXED IT!!

[Q] My Xperia Z is controlling itself

Hi guys,
I recently got my Xperia Z back from repair. I had it in because when I pressed the power button to unlock it, sometimes the screen would stay black and I wouldn't be able to see anything, but I could still use the touchscreen.
So I got my phone back with a new LCD screen and it's been a week now and it hasn't had that problem at all, but I'm having another problem.
My phone is randomly controlling itself. When I unlock it, every once and a while it starts pressing all the buttons on the screen. Opening up the task manager, swiping left and right, opening up the camera, etc. Just going completely haywire.
So to fix it, I tried a factory reset, but that didn't work. Then I got a new update for android, and for about a day it worked perfectly but now it's back at it again and controlling itself, pressing all the buttons etc. I had an alarm set this morning and I couldn't even turn it off because of it.
It's completely stock, I haven't even tried flashing or rooting or anything like that, and I'm running Android 4.4.4. Model number is C6603.
Anyone know what could be causing the problem?

there is some issue with touch calibration or some issue with the digitizer.

Well it happens before I even touch anything on the screen, so would that point to the problem being the digitizer?

[Q] Black screen of death ? Any survivors ?

Hello all,
I own a Z3 Compact since now 4 months, I bought it abroad, in Qatar and went back to Belgium after.
Overall, I'm very happy of it. Nothing to say.
Yesterday, the phone was almost full in battery, connected in bluetooth in the car... I tried to pick it up and turn it on, it wasn't working anymore. The screen stay black. I tried to turn it off, then on, impossible.
I tried to push the vol up and down then power button all together during 30 sec, nothing worked.
I tried to press the yellow button near the sim card, nothing helped.
I also tried to do all those combinations with the power plug connected, but even the power led is not showing up !
The phone seems to be turned off and I'm unable to turn it on again. I've read some forums and it looks like it's a common problems with Sony Xperia phones (ex: Link).
The date on the paper near the sim slot says 14W36 (Year 2014, Week 36).
I'm wondering if I should return the phone to Sony for warranty ?
If yes, do you think it will work even if the phone hasn't been bought in Belgium ?
Thanks
Tried Sony's FlashTool ?
Hi,
before I send it back, I would try Sony's Flashtool.
Search for "Sony flashtool"
Read carefully and good luck

Hello,
The phone doesn't even get recognized by any software on the PC.
Anyway, the phone will be returning in waranty tomorrow morning, I'm crossing my fingers.
Such problem makes me really wonder if these phone are worth it.
Hi,
The phone went back in warranty in a Sony repair center in Alsace (FR).
They replaced the motherboard, not the phone is working perfectly.
I hope I won't have the problem again.
