Z3V Won't Boot Into Anything Other Than Fastboot - Xperia Z3v General

Ok, I did something stupid and I'm just going to throw it out there. I wasn't able to root my phone through the normal method, but I was able to get it to work with kingroot. From there, I used the installer to install the Z3dualRecovery and everything was working fine. Both recoveries were working, phone booted up so I went looking for ROMs.
This is where I screwed up.I tried flashing a regular Z3 rom and now nothing boots.
When I hold Volume up and press the power button it vibrates once after a few seconds and then nothing happens.
When I hold volume down and power, it vibrates once after 2 seconds. After that it will vibrate twice every 10 seconds or so.
Holding the volume up and plugging in my USB WILL boot into fastboot.
Holding volume down and plugging in my USB will make it vibrate once, the LED flashes green, and then red. And it keeps doing that over and over.
I've tried pressing the white button next to the SIM tray and it does nothing, no matter how long I hold it.
So is there any hope here? I doubt I can do anything since the bootloader is locked, and I can't use the flashtool to flash the stock FTF since it won't boot into flashmode. I'm going to try the rubberband trick by plugging it in and leaving the volume down held down while it tries to boot and flash the FTF. If anyone knows another option I'd appreciate it before I accept I bricked the thing.

I tried to tell people no roms unless it's for the z3v specifically. your phone is done to my knowledge because verizon locked us out on Sony pc companion and I could never get flashtool to work with fastboot. If you are still with verizon call them tell them your screen quit working and there no water damage and you haven't dropped it.. I'm assuming your screen is black. they will send you a new one under the Sony warranty and you don't have to have insurance on the phone and don't flash z3 stuff or ask first. BTW you might want to go to a verizon store and play dumb and then have them call tech support from there if your phones in good shape you will have a new one in less then 48hours.

The screen does not turn on at all, you are correct. I dont think they would do anything though, since I didn't get it directly from Verizon, or would they? I tried talking to online tech support and they basically said "hold down the white button next to the SIM tray, oh that didn't work? can't do anything else" so I think I'm SOL here.

I would contact verizon if they are your provider. did you buy this phone new or second hand..then contact Sony our phones aren't really water proof so they are taking phones in when the screen stops working...does your led still work

Go online and add total mobile protection to your line right now its $11... Then tomorrow take that bad boy into your local verizon store and tell them that you were taking a software update and your phone rebooted and never came back on. I've been where u are it ain't a pretty situation but if you press and hold power volume up and volume down all at the same time you should still be able to boot into the stock recovery as long as you can get there they can't prove an ota didn't brick you and they'll send you a nice refurb.

he is way past being able to get to system recovery he flashed a z3 rom his screen doesn't even work..I would assume he can't turn the phone off either if it's not dead already.

Nah I've been there with that blinking red and green led light then straight to fastboot. I dont mean TWRP recovery...He's still got his stock recovery partition flashing a Z3 rom wouldn't flash his recovery.img... He should still be able to boot to the SONY screen and the factory reset screen options on the stock recovery... That and fastboot are the only things he can get into I'm betting anyway lol. It's a real ****ty, scary situation to be in.
You can always turn your phone off try it press and hold all your buttons till your phone shuts off. Keep holding them. You'll see the recovery screen im talking about... It has a power off option

Phone is kill, no screen at all and no possibility of recovery. I've tried all button combos, and durations without success. I'm just gonna request a thread close here, pay the stupid tax and learn from it.

[Q] Can't get into download, hardware locked?

First of all, I'm not sure if my Vibrant is "hardware-locked" or not - the battery has a date of 8/25/10 printed on it, the sticker behind the battery says "10.09." Either way, I cannot get into download mode. The phone was purchased 1 week ago today. I was simply attempting to disable the voodoo lag fix (using bionix 1.3 rom). I have tried every combination of getting the phone into download mode that I can find - is it possible? I sometimes think it's close to working because during the process a window on my computer pops up that says "hardware not installed correctly" which to me means that I was close. Someone please tell me if it's even possible to get my phone into download mode - it will start up, do the samsung galaxy animation, then go to black screen with the bottom buttons lit up. Thank you for any help you can provide - it makes me ill that I spent $500 on this 1 week ago and am now faced with a complete brick.

Try this:
Take battery out
Put battery back in
DO NOT TURN ON PHONE!
Plug in USB
Wait for the green battery screen
Hold vol+ and vol- at the same time
Hold power
When the battery screen goes black, let go power ONLY.
I had a HW locked phone and this method allowed me to get into DL mode--still couldn't get into recovery, but at least I could use ODIN. Was a null point as the phone is bricked and a new one is on its way...
When you say a new one is on its way, did T-Mobile exchange it under warranty even though it was rooted?

Neither of these methods worked. what are the chances of t-mobile performing an exchange for me if all else fails?
you could try this too, it worked for me.
remove battery and put it back in.
plug in usb
hold vol up, vol down and power button.
when you see the vibrant home screen, keep holding the three buttons until the screen turns dark.
let go the power button and vol up but keep vol down pressed, you should be in download mode.
hope this help.

Since we all seem to have our own variations of this method, I can tell you the one that worked for me 99.99% of the time on the first try when I was stuck at the Phone ! Computer screen.
1) Remove battery
2) Hold Vol - and Power
3) Insert battery while holding these buttons
4) Plug in USB if it works.
Some have reported T-Mo swapping the device due to the inability to access download/recovery mode, but it doesn't seem to be something they will regularly do. Others have been successful by using the inaccurate GPS issue to get a replacement. Specifically by insisting it is not just inaccurate, but downright non-functional.

Yea...I tried relashing the stock rom using ODIN--for 4 hours over and over. It said "successful" in ODIN, but the phone was toast (would go past S boot screen then nothing. Just walked into TMO, said it "just would not do anything" with a feigned puzzled look and after a amateur cursory inspection the rep. just did his thing on the computer and a new phone is being sent to my house via UPS.

Stuck at phone to pc screen + hardware lock phone = RIP

I've tried every possible combination ... literally tried everything and this quote from this thread http://forum.xda-developers.com/showthread.php?t=771247 just comfirmed it to me
METHOD 4: STUCK AT PHONE ! COMPUTER:
(and are not able to use vol+ vol- methods to access downloader/recovery)
CALL TMOBILE AND BEG FOR THEM TO REPLACE UR PHONE..
i cant believe its that easy to mess up your vibrant, my g1 never gave me a problem
did you try:
1. Phone starts OFF
2. Hold volume up + volume down buttons
3. Plug in USB cable
That is how I get into download mode. You don't ever hit the power button and you plug in the USB cable WHILE holding down the volume buttons.

This is the way, no power just volume up an volume down, or just volume down with the same method. Be sure you remove your sd and sim cards also.

I have a hardware locked phone and have been stuck at the phone to computer link screen (a rather nervous place to be, I might say). First you need to take the battery out (to turn the phone off). Then you plug in the USB with the battery out. Then you put the battery in. You need to get the battery charging indicator, and I can't remember if you need to unplug/replug USB for that or not. Then you hold down both volume buttons and the power button. The *second* time you see Vibrant (phone reboots twice) let go the power button. You should end up in download mode.

it resets back to the battery icon.
Basically, im in the exact same situation as El Cipitio. i tried EVERYTHING!!! no luck at all...
Can adb still see your phone? I'm guessing no, but if it can just use "adb reboot downlaod".
Then again.... you guys are aware that the "hardware locked" issue was fixed almost two months ago right? One of the members posted a thread with a zip and the JI6 update also fixed this. There fore if you didn't flash either you should call Tmo, but if you have, then you're just doing it wrong... GL either way.

One other thing to try is to remove the sim and external sd card and try the instructions I posted again. Really, if you get the pc to phone connection icon, you can get it into download mode and use odin to flash.
Dont waste your time fellas with trying to get,into recovery/download mode. If its anything like my hardware locked vibrant there isn't a key combo that will work. Probably thinking that your doing something wrong,YOUR NOT.
Im using my vibrant on att so I didn't consider calling tmobile. I actually called samsung, and after 5min on the phone they agreed to repair/replace for free. They recieved my phone on saturday amd I got it back that following thursday.

This is how I got it to work....
1. Take out the battery
2. Plug the USB into the phone
3. Plug USB into the PC
4. Hold down the Volume up/down + Power button with one hand
5. Put the battery back in with the other hand
6. Wait for the phone2pc icon to flash 2 times and on the second time when the screen goes black release only the POWER BUTTON
7. When you see the digging Android you can let go of the Volume buttons
That is the only way I could get it to work
No, I can't get it into adb mode. The phone bootup screen comes (vibrant, the pink tmobile thing, then galaxy s), but then it goes black. The computer doesn't find anything during this time.
I don't really have time to do the soldering, so i'll try calling samsung. Problem is i live in toronto and bought this thing for cash, so i have no clue what to tell samsung lol. If that doesnt work, i guess soldering it is...
Try this:
unplug, remove battery, remove sim/sd cards
hold down volume control buttons
plug into wall adapter (usb charger - not to computer but to outlet)
pop battery in
Took me a couple tries, but I got my Vibrant into dl mode from nothing but a black screen (I could not register charging, or "phone ! pc" error)

I'm am referencing more to the fact that these phones are not "hardware" locked. Hardware would refer to the volume & power keys not working... When your phone is on they work right?
Like stated before, IF, your phone is "hardware locked" look to either use the script or flash JI6. This way you re-gain functionality of the recovery & dl mode before flashing anything!
Ditto.. i got mine back after flashing without removing the lag fix.. never again... i will wait for froyo.. if that ever happens...
May I ask what bricked you?

The brick, in atleast my case, was from untimely removal of the phone from USB during Download mode of flashing stock kernal via Odin. This method described in the link above worked for me in getting the phone to boot into download mode without the use of the hardware keys (aka hardware locked phones). I also contacted Samsung directly through their Galaxy tech line, and they said I could send it in for free with their shipping label and if they couldn't flash back I could get a replacement, but there was a about a 2 week window I would be looking at without a phone, so I tried the homemade download-boot circuit and it worked perfectly.
THIS IS YOUR FIX!!!
I just did this the other day. If you are still stuck with the phone/!/computer screen do the following:
1.Hold the volume up/down + power button simultaneously
2.The screen will go black / reappear/ then go black again...when this happens, release the power button and continue holding the volume up/down button
3.Welcome back to download mode!
Please Mods, please lock this thread
Please stop waisting everyones time with stupid instructions.
When a phone is "hardware locked" (that is, bad flash/missing the sbin file.....)
YOU CANNOT GET INTO DOWNLOAD MODE OR RECOVERY WITH ANY KEY COMBINATION.
Stop waisting your time trying anything cause its not going to work. And thats a Fact.
Final fix and summary to this thread,
Either call T-mobile or Samsung.
Finish.

[Q] battery problems/won't charge... what to do....

Today i decided to try out the nocturnal rom, but before that i had to make a backup. at the the time the phone was what i would a call luke warm so i paid no mind to it. so a few minutes later i look back at the phone and notice that the screen turned off annd the phone was now averagely hot
so i let it cool down for a bit (i thought that the phone must have shut itself off in order to make sure the internals wouldn't be damaged), then when i try to turn it on the lg logo does show up but never gets to the base roms nexus boot animation, now i'm thinking that TWRP must have drained my battery because when i usually make a backup my battery can go from 94% to 50% in a span of 7 minutes (only during backup). So i leave it to charge for 30 minutes 1 hour and then 5 hours but each time i check it still won't turn on correctly.
Now i have had this happen to me before, when i had the atrix 4g this happened and i had to buy a battery only charger to even get it to work again
but as we all know that won't work for the optimus g because you cannot take out the battery.
so i have to ask, what should i do? is there any way to fix this?
Side note: can't get into recovery (seems to shut off before it loads up, its like an infinite loop of dying and turning on again) the power button still glows while its connected giving the appearance of charging but it still never boots up all the way ( the most i can get it to is the part of recovery before going into TWRP. you know holding vol+ and seeing fastboot mode)
There is thread here someone made of disassembly. You can do a battery pull pretty easily. Never know might help.
Have you tried download mode at all BTW?
Sounds more like something was deleted then a batter problem to me. If download mode works you could try lgnpst back to stock.
The information in THIS thread might be able to help.
I can't vouch for it because I haven't experienced these problems, but the OP there seemed to get his problem fixed.
GL.
Although, looking things over, sounds like you have a different issue.
So you can get to the bootloader?
from the bootloader have you tried hitting the volume down key twice then hitting power?
That should reboot you into recovery, where you can restore something or flash stock.
Edit. Quote from FreeGee post.
To enter bootloader, hold volume UP and power.
Upon entering the bootloader, you will notice that there is no 'menu' to enter fastboot or recovery. Unfortunately, since the stars didn't align properly, we were unable to tell the new bootloader where to load the images that contain the menu from.
In light of that, you'll have to navigate the menu blind. Use the volume keys to change selection, and the power key to select.
The choices are (in order of pressing volume down):
Start - boot the phone normally [already selected]
Restart Bootloader - reboot into the bootloader
Recovery Mode - enter recovery (CWM)
Power Off - powers the phone off
So, to get to Recovery, you would press volume down twice then power.

also i have no idea what download mode is but since nothing seems to be working i will assume that does not work either

Amazon is actually VERY easy to deal with, and a HELL of a lot easier than AT&T. They'll ship you out a replacement, you send the old one back once you receive the new one. Done. You MAY have to send the old one first, but if you let them put a hold on a credit card, I believe they'll definitely ship first.
You may be able to fix this by holding down both the volume down and power buttons for at least 45 seconds after you plug in the phone.
so
STEP 1: PLUG IN PHONE
STEP 2: PRESS AND HOLD THE VOLUME DOWN AND POWER KEYS TOGETHER FOR AT LEAST 45 SECONDS
STEP 3: LEAVE PLUGGED IN FOR TEN MINUTES
STEP 4; BOOT INTO RECOVERY MODE, WIPE BATTERY STATS, WIPE CACHE, AND WIPE DALVIK, THEN REBOOT TO SYSTEM FROM WITHIN RECOVERY.
LAST PART IS TO PREVENT IT FROM HAPPENING AGAIN.
I've gone the three of these for various reasons and some times lgnpst pretends to work and you need to do it again. And some times you need to wipe data boot back into download and do it again. This phone is retarded.

[Q] phone won't turn on after update

bought my OG lightly used on ebay, arrived running ICS
after rooting and playing with it a little I decided to update to JB so I did a software update
at/near the end of the update (don't know if it got to finish) my phone just turned off and won't turn back on
the battery isn't dead and no combination of volume keys plus power button will get it back, nor will holding the power button for an extended period or plugging it in
what should I do? I'm kind of disappointed that a simple upgrade will so readily do this

the battery isn't dead and no combination of volume keys plus power button will get it back, nor will holding the power button for an extended period or plugging it in
what should I do? I'm kind of disappointed that a simple upgrade will so readily do this

If you plug into PC while holding both volumes and power button, you will hopefully get a screen that says download mode. If so you can use lgnpst program to restore phone. You can get lgnpst from irc channel.

no dice
before trying this I took the back panel off and unplugged the battery and nothing changed
getting no response whatsoever out of the screen or notification light

I think the post above should fix this. Maybe your trying it wrong. I had a soft brick, i believe its simular to what you have. Does your phone boot up, stay at the boot screen, then reboot and back to the boot screen?
You have to get the timing correct. Be precise. Make sure phone is off. Hold the power+volume up+volume down until you see the Download Mode screen. I dont see why it wont work unless your doing it wrong.. Keep trying. When it gets in download mode just open LGNPST, and get correct files (im assuming you have them?) and boom.

the screen is completely blank no matter what I do
anyway, I fixed the problem by arranging a return for a full refund
I don't feel it is right for you to receive a refund when phone was in working order before you rooted it. If you had purchased it new and not from an individual, it would be acceptable.

the phone was working fine after I rooted it, the OTA update is what killed it
I have no way of knowing if rooting it beforehand had anything to do with it
I also didn't buy it from an individual but a wholesale company on eBay

You shouldn't try to OTA update on a rooted phone. The only thing that can come out of that is trouble. You should've LGNPST to 20j then rooted it. Your very lucky your getting a refund for a user mistake.

Hard bricked?? Kiw-L21

I think i dun goofed on the worst possible way. My phone is kiw-L21 So i flashed cm13(http://forum.xda-developers.com/showpost.php?p=67863454&postcount=1877) and gapps and the b330 package so you can get the fingerprint sensor. and than i rebooted and my phone just went black. Did i do something wrong and is there a fix available. My phone wont do anything. it wont even bootloop or anything else. i tried all the button combinations and i tried connecting it to my pc/charger. nothing. If there isnt a fix for it would i be able to return it to my seller and will they notice anything? I really hope i haven't hard bricked my phone

is the phone actually off of just frozen on a black screen ?
to power off hold power + volume up for about 30 seconds
to get into the bootloader plug in PC usb and let it set 5 minutes then hold power + volume down till the bootloader comes up

I tried the 5 minute thing you said and i held the buttons for almost 2 minutes and still nothing. Are there any other possible ways to get it alive again?
So i have tried everything and now im thinking about getting it jtag repaired. It would cost me €40 ($44), Is this too much for a jtag repair or should i just say f**k it and send it to the guy to get it repaired?
I dont think i have got allot of choices left.
