help please

hi friend , i really need some help here

my device have no system/kernel now .. i've been trying to flash a kernel via fastboot but it always tells ( failed - remote : command not allowed )

as for flashtool .. whenever i try to boot into download mode the led turns red then green in a second then disconnects it self by only booting to sony logo .. even tried to charge thinking it's only a charging problem .. but it won't even show the charging animation , do you know how to fastboot flash kernel successfully , ps : am not a noob , just haven't done this for a long time studying high-school .. means you can ask me anything about the process . am on LB BTW

really need your much awaited halp , or any other dev ..

and what is it required to fastboot or flashtool ? could be a wrong drivers issue ? , i alredy tried two drivers !

more about the problem .. i was flashing eXistenz 5 black and its superuser fix , which was done successfully then i had to flash a kernel via flashtool which didn't go well , i thought it's because i forgot to check usb-debbuging of dev-option so i had ( deleted data / cache to flash a new rom , tells the cwm recovery ) to flash the eXistenz 4 back , which had formated the whole system/data/cache and everything .. and ever since it won't fastboot or flashtools or even recover into recovery as the kernel should be deleted ! i think the device is gone heart-attack as dead

Edit : flashtool needs usb-debbuging on which in my case is not

am left with fastboot to flash a kernel and have a recovery , would someone please at least try to help ! ?

[MENTION=4610000]parasitical[/MENTION] flashtool will work just fine in flashmode without usb debugging on. The 2 are unrelated.

Flash a full ftf of a stock rom and your mobile will work just fine.

If you have a locked bootloader you must flash a stock kernel.sin from Sony otherwise your bootloader will refuse to boot, simply because it's locked...
[Xperia Z General] parasitical:
thanks for your time ,

i've been flashing a boot-twrp-v2.img kernel which is for LB via fastboo , and a .tft kernel via flashtoo , do you mean flashing a .sin kernel , .tft stock rom would work .. if so , could you pleaase give me a link to a stuck kernel as i haven't found any , and a is there a tft rom for the ME ?

am really gratefull for your help !

thank you sooo much , you are the best
[Xperia Z General] [NUT]:
You are welcome :)

Stock kernels can be custom as well, remember that Sony signs it's kernels and the S1 bootloader checks that signature. If it matches (pure stock) it will allow to boot on a locked bootloader. Modified stock kernels lose this signature, hence your need to unlock the bootloader to make S1 accept the kernel without that signature.

i downgraded to .534 firmware on my z1 on locked bl and my imei reset to 0, then again i install the stock .290ftf via flashtool and my device won't powering on, only combination of vol up and power key working and it vibrates but flashtool does not recognize the device. tried all the methods.

help me???
[Xperia Z General] [NUT]:
Download one of my stripped ftf files from my rom thread. Maybe yours has been damaged.

Disconnect usb, turn off the device (which is what you are doing with vol-up+power) and then get flashtool ready to flash. Then while holding volume-down, connect usb.

Let me know if it worked :good:
[Xperia Z General] deepongi:
i hard bricked a Z ...

symptoms same as other user:

anyone now how can i revive my Z?

many thanks,

[Xperia Z General] [NUT]:
Well... The chance of unbricking your Z is extremely slim, but the main question is how you bricked it in the first place?
[Xperia Z General] deepongi:
bad built boot.img... :( it was meow kernel compiled by myself but a friend a mine altered the flash script. after flash it, the phone is completely dead, with the symptoms above.

an official sony repair shop can fix it, right? and they wont be able to tell if the bootloader was unlocked or not, because its corrupted..?
[Xperia Z General] [NUT]:
Well... I won't be able to tell you that unless you share me a link to that bad package (IN A PM PLEASE!) to see what the flash script did ...
[Xperia Z General] [NUT]:
[MENTION=5566338]toscapaul[/MENTION]

It might have been a long post, but it's complete :good:

One thing I can suggest you now:

Get USBDeview to remove all USB device drivers from your system (vendor ID = 0FCE), run it as administrator for it to work OK.

Then reinstall the flashtool drivers on your system and try to get it to boot in to flashmode.
[Xperia Z General] [NUT]:
I've checked the packages you sent in a link to me by PM, here's my verdict:

You're screwed... but chances are Sony will only be able to detect user error with highly specialized hardware, which most service centers are not equipped with... so, you could roll the dice on that...

This is the reason why:

Observe the highlighted line and then look at the screenshot below:

Your kernel got written to a partition which belongs to the bootloader (p5) ... and that can not be rectified :(

I was working on a solution but to really test it (and work on it some more, it's not done!) I would need to brick my own XZ :laugh: ... or get someone to send me his/her bricked phone... and even then there is no warranty it will work out OK.

Anyway... the 'friend' who did this is probably a Samsung or HTC buff... but he clearly knows nothing about Sony devices, sorry but he made a mess of things :eek:
[Xperia Z General] toscapaul:
.... ooook.... the strangest thing happened ... after being tired of trying things and out of options i have put the 10.3.1.A.2.67 fw back with flashtool the only thing was that phone vibrates, the red light appears and nothing ... and put the phone aside , i thought i have shut it down but probably since no image appears was on... as battery was to 80-90% in twrp before flashing stock ... if there is displayed accurately that is.. anyhow put the phone to charge today as it showed three red blinks when started and surprise the sony logo appears and the animation with battery charging .. let the phone charge till green light and am able to boot into os ... the pc shows the phone as Xperia Zl in flashtool sus or pc companion and everything seems to be working as nothing happened

... now the question .... once the battery is depleted is there any part of memory/flash that gets wiped out/reset ? my reason is that 2 days ago with the same software and settings phone was not starting being softbricked, did not touch the thing at all and once battery depleted and recharged it all works as it should ...

also was curious if there is any option to actually display some level of messages on display while booting , to my knowledge so far this should be something built in kernel but could not find anything appropriate , will do more research on adb logcat command ... that is the closest i could find

Anyhow, the big question is what changed that brought it back to life ... sure was no change from my part ...

will restore TA partition with Drm keys made before unlocking the bootloader just to be on the safe side in case it does happen again

LE:

Just for the sake of it .... i have done the following:

unlock bootloader

fastboot flash boot boot.img (from cm10.2 which was installed previously and had it running fine for 2 months)

wiped everything in cwm

installed cm10.2 rom

now am back to softbrick again

wiped everything again in twrp

flashtool flash stock rom

lock bootloader

flash stock rom again

the phone is still softbricked

before the last flash the battery was somewhere at 15% ... i will start the phone and it will vibrate but nothing appears on screen ... and leave it like this for a couple of hours ... until battery is completely drained aka not starting when i pres power button

plug the phone to wall socket and let it charge for a bit

i power it on and voila.... sony logo and battery charge animation

Now i am quite intrigued to find out what i am missing ... what is changing in the state of the phone that after battery depletion can boot properly?

Had more time to kill

went back and unlocked the bootloader, installed back cm10.2 and restored the back-up i had previously with all the apps installed

phone still would not boot so i let it open in cwm till fully discharged again ... connected it to wall socket and now am able to boot into cm10.2

will have to do more research/learn more about how bootloader / os startup works ... but for now does this behavior seem normal?
[Xperia Z General] jobangill99:
I put my z1 into charge even it is not charged. After 3 hours battery led showing up and after it is recognized by flashtool then now it is working.
[Xperia Z General] bananaclips:
I've read this entire thread now to get an answer to my problem and there were quite a few people with the sony logo-bootstall problem, but as I haven't found a solution yet, I'd be glad for some help.

I had tried to flash CM 10.2. via CRM on a locked bootloader after rooting my .244 C6603 with Doomlord's method (http://xdaforums.com/showthread.php?t=2386405). i was under the naive impression this wasn't a problem, as I'd seen talk about flashing CM with a locked bootloader via rommanager.

anyway, i had a soft brick, got to it via fastboot and got to the bootstall/flashmode stage by pressing "reboot device into system" in fastboot.

after trying the .sin .244 kernel out of the above thread via fastboot (not possible due to locked bootloader), i went on to try and flash the whole ftf (XperiaZ_C660X_KernelOnly_10.3.1.A.0.244_BE) in flashmode via the reboot-and-volume-down-method both ways, excluding and including kernel.

the flashtool log keeps saying that flashes are completed successfully. however, nothing changes about the bootstall problem.

SUS, using the same button pressing method, says that the latest software is already installed on my phone and that's it.

concluding, I have the sony logo repeating every couple of seconds, fastboot and flashmode both still possible. Is there anything else i could try? for example, unlocking the bootloader at this stage? or doing something with the system backups i had CWM/Philz Touch do on my micro sd card beforehand?

Any help would be appreciated. :fingers-crossed:
[Xperia Z General] shoey63:
Just download and flash an ENTIRE ftf (not just kernel), with wipe boxes ticked.
[Xperia Z General] bananaclips:
I flashed the following ROM

[STOCK ROM][FTF] Xperia Z (C6603) 10.3.1.A.0.244 Generic NL (Unbranded/Netherlands)

http://xdaforums.com/showthread.php?t=2386840

and it worked :)

For some reason it went without the button-pressing, I just connected the phone and it started.

Thank you so much. I am relieved beyond imagination. :) You guys really helped me out.
[Xperia Z General] madcaz31:
Hi nut,

I also have a bricked Z .

I am not sure how the phone was bricked as i received it that way.

The phone does have led response, 3 flashes or 10 seconds then off depending on presses, but no vibrate.

When connected i get QHSUSB_DLOAD

I got hold of a cradle for charging to see if that was the problem left it for a few hours but still no luck (will leave overnight too)

I did manage to force some sort of qualcom driver on but to no avail could do it again if needed

Hope you can help :)

Try to contact [MENTION=3665957]the_laser[/MENTION], who made the Z1 hardbrick recovery software: http://xdaforums.com/showthread.php?t=2646405

As long as it's only your bootloader which has been screwed up, you will have every chance he might be able to fix it.

Xperia ZL 6503

hello, i have the same boot stall on this thread and tried everything from page one but no luck...

http://xdaforums.com/showthread.php?p=50745349

i have C6503 10.4.1.B.0.101 4.3 rooted.. i hope anyone can help... thanks

EDIT:

Successfully replaced busted battery from Sony Xperia ZL C6503...

the battery is new and got it from sony service center, i told them that i will install it myself and they send it to me since its out of warranty.

i dont have the pics while i disassembling it since i only have one phone :)
[Xperia Z General] skyline_slo:
I think that we're one of the few ZL owners that have that same problem..

everytime I turn off the phone, I can not turn it on again (it's soft-bricked) so I have to wait for few hours and then I can charge it again and turn it on again

I searched a lot through forums, but I never found that same problem, until now.

I never unlocked bootloader (i'm kind of new with smartphones..), the first time that that happened was, when I updated device through update service in phone settings and when I tried to turn it on nothing happened.. then I flashed official sony ftf' roms with flashtool and it's always the same (soft-brick)

on the first page says you should try to repair softbrick with flashing the kernel with fastboot mode, is it like this? https://www.youtube.com/watch?v=IXTzA7Qrrv4

where can I get stock Sony kernel image for ZL C6503 (10.4.1.B.0.101) 4.3?

thanks for any advices and help
[Xperia Z General] skyline_slo:
which one did you mean by second method?

fastboot for kernel or flashmode & fastboot for reunlocking?

my phone is not relocked, it just wont turn on when I turn it off, I have to wait for a few hours and then I can turn it on again (I even changed the battery, but I have the same problem..)

another strange thing was, several times when I turned it on (after a few hours) the battery was at 1%, but when I turned it off was fully charged..

[Xperia Z General] toscapaul:
nope, got rid of the phone and got a galaxy note3 instead
[Xperia Z General] skyline_slo:
I was thinking the same, I was looking Z1 and Z2 but they are just too big, ZL is perfect size for me, so I'm still trying to resolve this

My ZL doesn't start anymore.

I've tried re-flashing some stock roms via flashtools and a recovery with SUS.

But it continue to show only the SONY logo and then die...

How is this possible? I bought it 2-months ago...

I'm kinda disappointed with sony. My wife has an Xperia SP and after the last official update, the system has turned into a nightmare...

I'm trying to follow your guide to recover from a bootstall, Update service just tells me I have the latest version and flashtool sits on "Preparing files for flashing" Have I bricked my phone or am I just a fool of a took?

I am using an Xperia Z1 C6903

I was in the process of going from C6903_14.2.A.0.290 to C6903_14.3.A.0.681.

I was following the 20/03/2014 update, which said that I could follow the last few steps. Everything fell apart whilst I was in recovery, when I was doing that actual install via the zip.

After confirming the flash, the phone turned off during installation. Which as I type I fear already does not bode well for me.
[Xperia Z General] [NUT]:
It actually sounds a bit like your battery just ran out... but you do see a sony logo when you power up your device?
[Xperia Z General] Foolofatook:
I think I had about 15% left, but it sounds like that might have been the case

Yes, I see the sony logo and it just hangs there.
[Xperia Z General] [NUT]:
Hook it up to the charger and leave it hanging for at least 30 minutes.

Then flash any ftf which you have with a boot folder inside it (open the file with winzip), flash only the system and kernel, not wiping anything.

Then charge it to full before you continue.
[Xperia Z General] Foolofatook:
Will give it a shot in the morning, will get back to you

Thanks so much for your help, will sling you a few bucks when I get paid next
[Xperia Z General] Foolofatook:
Nut, you are the most beautiful of human beings. All is working, I was doing the exact opposite in your bootstall guide and flashing everything but the system and the kernel. Thank you so very much.

i have a bootstall and my sony pcC doesn't detect my c6603. i try to repair anyway but sony pcC says "no new software update" :(:confused::(
[Xperia Z General] [NUT]:
Well, then don't use PCC... Try using either flashtool or sus to flash.

Use one of the guides in the OP to guide you.
[Xperia Z General] sonyhack:
i did it with many .FTF's and doesnt seems work. i follow unbrick treads and doesnt work either :crying:

I think I'm going to take it to a cell phone fixer :rolleyes::(
[Xperia Z General] [NUT]:
What does your phone do and what doesn't it do?

You have said you have a bootstall, which means you have a sony logo and then nothing happens?

If so, disconnect USB, press power and vol-up at the same time and hold it until you feel your phone vibrate 3 times.

Then take flashtool and get it ready to flash an FTF, choosing what you think is safe to do (if you don't mind losing everything on the phone, then do a full wipe). Make sure it's on the screen instructing to connect your phone.

Then WHILE _holding_ volume-DOWN, connect your USB cable. You can let go of the volume key once the flashtool 'connect device' screen disappears.
[Xperia Z General] sonyhack:
seriusly guys i flash many .FTF's and not working. filmwares bellow .101 gives a bricked phone and .101 it's bootstall

Hi

I have do exactly what you said but I can not get out from bootsall. I used flashtool,
[Xperia Z General] whazz_up:
very interesting.
[Xperia Z General] dizzyb0y:
flashtool way didnt work for me aswell but i tried the SUS way and it worked perfectly, you should try it
[Xperia Z General] 98thomas:
What to do? Plz help!

I have a guestion, my xZ is somehow got in a bootloop. This all started yesterday morning.

I didn't had internet connection, so I decided to shut the phone down and then started it up.

This wasn't the problem, but when I wanted to unlock the screen, nothing worked the screen just freezed.

I only saw a black screen and after 30 seconds it just shut's down and then it starts up again, so it's in a boodloop.

After my battery was empty I fuly charged it. (When I put the Z on, it is going in a boodloop).

Luckily you don't need to put the Z on if you're restore the Z in PCC. So I have restored my phone

and everything just worked how it should when you're restoring a phone via PCC, but when I put it on,

it was still in a boodloop.

So this is wat happened.

Maybe I can send my phone back for a few weeks to Sony,

but maybe you can help me, do you guys have any idea what's going on and how to repair it?

I've tried to boot the Z via SUS but that also don't work.

When my phone starts up it says: 'The system is not working' And then it just starts up again and again..

[Xperia Z General] crazymister:
Did you restore it including data wipe? You could try that, also try what happens if you remove your sd card, just to rule out a bad sd card, also try booting without sim.

Let us know how it worked out

hi

I've "soft brick" problem on my ZL 6503 (bootloader locked) for about a year now (when I turn it off, I cant turn it on again, when I try to turn it on just vibrates and that's it.. I have to wait for about 4 hours and then I can start charging it and then turn it on..)

the problem first happened when I updated it through pcc from 4.1 to 4.2, before worked normally..

then I flashed it with flashtool, (original sony ftf rom) but the problem is still there..

should I try flashing only kernel? if so, should I try with flash mode (only kernel) or fastboot mode?

tnx
[Xperia Z General] [NUT]:
Dude, seriously: you should have backed up data and just have returned the device to Sony while in such a semi soft brick state...

I think these issues are caused by problems with the internal storage and specifically the bootloader bits.

The reason why it sometimes works and most of the time it refuses to boot is because of the emmc storage wear levelling... Sometimes you're just lucky enough to hit the sweetspot...

If you still have warranty (Europe as in the 'EU' warranty is 2 years, NOT ONLY ONE!), backup data, wipe your phone with a full ftf flash, take out sdcard and sim and return it to Sony or take it to a service centre. They should replace it whole or just the mainboard, no questions asked.

Just make sure they understand it only works after flashing it a gazillion times and repairing it using pcc an equal amount of times to get it to do ANYTHING. If you do, they probably won't bother to 'fix' your phone.
[Xperia Z General] skyline_slo:
first thought I had was, I have to return it to sony... but I bought it in germany when I was there for work and I'm from slovenia and I didnt want to send it by mail.. the problem is only when I shut it down and I cant turn it on again (I have to wait for few hours), I think it's something related with battery (I even changed it), because after few hours when I start charging it, it from 1%, even if it was fully charged when I turned it off

when the device is on, it works normally

you think flashing only kernel would not help?
[Xperia Z General] [NUT]:
No, I think your device really needs to get checked by Sony...
