[Q] Stuck booting - Xperia Z Q&A, Help & Troubleshooting

My 6602 won't boot. It hasn't gotten to the part type my password to decrypt storage.
I also can not turn it off. I hold the power button in, but nothing happens. So, I can't flash it for example if I wanted to.
Help.. Do I really have to wait until the battery runs out??

Ok. I figured out I can get it to turn off using the volume up trick, but it must of been stuck? I had to hold it for quite a while then it did the single vibration, rebooting it.
I can get it into flash able mode now with the three vibrations, forget what they call that mode. Similar to DFU on iPhone..
Mods - you can delete this thread. Sorry.

[Q] Problem booting into Recovery

So.... Been playing with this for the last two days trying to root this phone.
I've rooted a few other phones, so I do have experience with the overall process, but I am unable to even boot this phone into Recovery. I have tried booting into recovery by holding down both volume buttons + power and from adb terminal "adb reboot recovery."
Neither method works. The phone will boot (or reboot from adb) and brings up the "at&t World Phone" screen and then nothing else appears. The first time I tried this it actually wouldn't boot up even after pulling the battery and trying to start normally, it still sat at the same screen. I let it sit all day today at the screen until the battery died. I was finally able to get it to boot up earlier.
If anyone can help, that'd be greatly appreciated. Let me know what info I need to add.
I usually just press and hold both volume buttons and power then release just the power button and keeping the volume buttons still pushed on the 2nd time the white at&t screen pops up... Works for me every time.

hold volume up+down and power key btw this is wrong section to post supposed to be in general
Oh sorry, didn't realize it was supposed to be posted in general.
I've tried the Volume Up/Down + Power and this does not work, as I stated originally.
I've also tried to do it from the adb shell, which also does not work.
Does anyone have any idea why I can't access recovery?
I"m having a similar issue. Holding volume up+down and power and releasing in any combination just boots the phone up. If I just hold volume up+down and power the phone alternates between the AT&T World Phone screen endless.
Yes u have to let go of the pwr button when the phone screen turns on

I've tried just about every combination of the Volume Up/Down + Power and no luck.
I've also tried the following ADB commands, with no luck, it just reboots the phone:
adb reboot recovery
adb reboot-boatloader
When I hold Volume Down + Power I get the a Yellow Triangle with a Android guy with a shove with the text "Downloading... Do not turn off Target!!!"
When I hold Volume Up + Power I get an Android guy with the following text: "POWER RESET or UNKNOWN UPLOAD MODE"
For kicks, I tried to to flash a rooted update.zip via the Volume Down + Power way with the Samsung update software, the same way I have done with the Samsung Moment. Wasn't sure if it'd work, but worth a try.
Any one else have any ideas or suggestions?
Phishie, do you have a final release version? Or anything special about the phone you have?
I just press the two volume buttons first (to make sure theyre pressed before you hit power), then press the power button, as soon as the screen turns on, I let go of everything and it works just fine, no need to have ridiculously complicated instructions.
The trick is to make sure both volume buttons are pressed BEFORE you hit power. Then release. Easy as pie
Also, if you guys are having too much trouble, just download the one click root/unroot. It will run, boot your phone into recovery, then all you have to do is scroll to install packages with volume key and hit power. Done.
Trust me, I am making sure I'm pretty the keys completely. I've literally tried it fifty times by now.
And I've also tried the One Click Root. This does not boot the phone into recovery either. It just sits at the AT&T World Phone screen forever and will actually get stuck here and will not boot up normal even by pulling the battery and powering it back up. It'll just get stuck at the for-mentioned screen. I have to connect it to adb and reboot it there to get it out of the loop it's stuck in.
that doesnt sound good. Maybe you need to try a factory reset? are you running stock rom and everything?
When I first got the phone I did a factory reset.
Yea, it's completely stock to my knowledge. But I have a different ROM than the final release version that everyone else has. This is a pre-production device.
same problem
I try all the combos as well, no luck, would the combos be different for 2e vs 3e recovery?
I try combo, it powers on, the same thing happens, the at-t comes up, goes for a second, then screen brightens, wait a bit and then the home row buttons light up, hangs there... doesnt matter which kernel or which rom I flash, same thing, adb and other stuff wont work as they need usb debugging enabled, which mine isn't.
Is there a way to mod the phone files and flash to enable usb debugging? Anyway to remap the buttons to 2 button vs 3 button?
Everyone post your methods for entering recovery please?

Recovery Mode with three buttons

I have read over and over again that you hold down both volume buttons, and the power button, and it'll boot into recovery - but it's never worked for me. Last night, by accident, I let go of the 'up' volume button, only the 'down' was down along with the power button and low and behold - recovery mode. Is this proper procedure maybe only for certain phones? I was so frustrated, all that would happen with three buttons held down is the AT&T logo screen would flash on and off. I guess I'm just looking for affirmation here.

It's always been a fickle thing for me. I just use ADB for recovery.
Turn on USB Debugging, open cmd prompt in Windows, navigate to where you have android\tools, then adb reboot recovery
I prefer it because it is reliable. I know I can do hardware keys to recovery but I always seem to require 3 or 4 tries before I can pull it off right.
Thank you - I'm definitely going to have to get more familiar with ADB. I have it set up, but I've never used it. Reliability is what I want, I really don't like the panic attacks in the middle of a ROM install!
Let GO
I think you missed an important step of the process of getting into recovery.
After you see the AT&T screen the 2nd time, LET GO of the power button.
Some phones are quirky about which button to let go of, and according to some posts, european builds do it with just one volume button and the power button. (I think)
Anyway, glad you got there, but be sure to let go of the power button next time.
Out of curiosity, does download mode work?
I can get into download mode with Odin no problem, but not with just the buttons, unless I'm doing that wrong, too.
I did try letting go of the power button, but all that did was boot the phone.
These things are so tricky, and the panic swells when it doesn't work and you're trying to flash a ROM for only the second time in your life!
I know the feeling... when your heart starts racing in your chest..
Been there.

Hello everyone,
I cant use the 3 button combo at all to get to recovery mode. I've done the "Down Vol., Home, and Power" before and it worked. However, i am not able to get to it after i flashed Bionix-v 1.2, and 1.3. I pretty sure its not because of the ROM, but i just can't figure it out WHAT! I've tried the "Vol. UP, Down, Power" as well, but still not luck. Please help!
Thanks,
Yahase

Turn your phone off, and plug in the USB cable. That worked for me.
While your phone is switcher off, press and hold both the Up and Down buttons in the volume. And then plug in the USB.

[Q] Sprint HTC ONE stuck on white boot screen

Hello,
I've just installed this ROM after wiping Cache/Delvik Cache and system wipe.
Now the phone is stuck on the boot screen and I can not get back into recovery to sort it out.
I held down power & vol+ buttons to get into recovery but nothing happens. The Home & Back buttons flash after 3 seconds then nothing happens.
Any thing else I should do to get into recovery ( TWRP)
My friend whop is a member asked this question on the Developers forum and so far no luck.
we have tried the following:
This is suggested by chogardjr: Plug your phone in to charge. Don't use a USB port for power. After you plug it in try the hard reboot again.
PLEASE HELP
Just for the sake of testing... Have him hold power without holding the volume. It should force reboot, not to the bootloader, so he can get a feel for how the reboot works. It can be finicky during a bootloop cause there are processes trying to run in the background. But it should do it if you hold power long enough.
Edit:
Also find out if the charge light comes on when he plus it in.
Tried and no joy.......

I had a similar problem with a bad kernel flash and could not get the device to shut all the way off - thats why the keys are blinking. I plugged it in to a charger, left it like that for a few seconds, then unplugged, held it under a bright light and waited. After a few more seconds, it shut all the way down and I was able to boot to recovery in the usual way (power+down). You may have to try combinations or maybe not. But, you won't get to recovery until the phone shuts all the way down. High light under in the 'eyes', plugging and unplugging, and holding the power button for up to 30 seconds are all known ways to do this, but as was said before a bootloop has processes trying to run, so the machine can be 'confused' and have difficulty shutting down. Hope you are successful...
Thanks. I actually got it going with one of the answers posted for me, by powering it off under a bright light.
Sounds daft, but it works.

[Q] Could anyone please confirm if it's totally bricked?...

Verizon HTC One
I'll tell you guys the whole story of the phone, in case you find something related to the actual problem in here.
All started when a friend of mine got me interested in ROMs and other modification his phone had.
I learned by myself all I needed to in order to Root, Unlock, and S-Off my phone, also I wrote the SuperCID to it (11111111) and installed the Custom Recovery.
It gave me a little trouble, but it was all good at the end.
Now was the time of the truth. I was about to flash my first Mod ROM, which was Android Revolution HD 71.1 .
Seconds after a successful installation (yay) I go and decide to reboot my phone, only to realize that what I just had installed was a Mod ROM for AT&T (I think, at least not supported to mine) HTC One.
Thanks to this, my phone got stuck in a bootloop, that at first made me panic a little bit, but then I saw that I could still get to the bootloader, and after some days of reading and what not, I got it to work again. Fully working, everything from a stock RUU, all nice and pretty.
"Then, where is the real problem?" you may be asking. Here it goes:
5 minutes after I finally got it fixed, I got all and exited and decided to flash a ROM properly this time.
I put the ROM inside the phone's internal memory.
I reboot phone.
It gets into bootloader.
I go and choose Recovery.
Here's where the "whoops" happen.
Since I had just installed a brand new stocked RUU, the Recovery also returned to stock, which I didn't really think that would happen by then.
Obiously, or at least it was what I thought by then, to flash a ROM I need to flash a Custom Recovery first.
So, following, even though I had already chosen the "Recovery" option, and it loaded, while it was doing a god-knows-what, I turned my phone off, which I guess and would assume that interrupted some kind of important process.
After that, my phone rebooted, and I was like "Phew, ok"
But it wouldn't get past the white screen with the HTC logo. There, after some 6 to 8 seconds, it rebooted, infinitely. It wouldn't turn off either, just reboots.
Like, at first I thought I'd need to call an exorcist, the damn thing seemed like it had the devil inside or something, acting on his own.
Then I realized it was that I had just screwed up everything, again.
So, resume:
I turned off my phone while it was on a Recovery's process.
After that, the phone wouldn't get past the white HTC's logo screen.
It would reboot, load the logo, and, after some 6 to 8 seconds, reboot, infinitely.
It wouldn't turn off either, I had to wait for the battery to die. Also, after this, when I plugged it to his charger, it turned on on his own again (the devil!) and started the same rebooting process.
So, what do you guys think?
Should I really call it a total brick? Do you think there's a way to fix it? Should I consider throwing it into Holy Water?
Notes:
-Can't get into bootloader.
-Can't flash boot
-ADB doesn't works on phone. Yes, I already had all kind of drivers since before, it just doesn't now.
-Can't get to recovery either.
Please answer, I'm lonely, I have no friends.

Thank you for reading.
Hold down the power button and the volume down together, keep holding them, don't let go, the lights on the bottom will flash 10-15 Times, when the phone goes off, let go of the power button, but continue to hold down the volume down button, the phone should boot back to the bootloader, devil gone, I think you know what to do from there, first get a custom recovery on there, or run the ruu which you ran before to get stock Rom back on it.

Also, lights never flashed. As I said, it reboots before the lights even blink.

Can't post "fastboot getvar all" since I can't even get to the bootloader and fastboot.
I don't think problem is anything I flashed. Last thing was the RUU, and you can trust it was 100% functional.
Hell came down after I turned off while in stock's Recovery.

If the phone is getting to the white screen with HTC logo then your bootloader is ok, a brick is when the phone won't switch on at all, you just got to keep trying to get into the bootloader, once there, you can just run the ruu again

@Seanie280672 you forgot the bright light
OP:
B) Force reboot
Press and hold POWER + VOLDOWN (under a bright light, not kidding!!), after about 5 seconds or so buttons should start blinking, and after 30 seconds or so, the phone will reboot, let go of POWER, but keep holding VOLDOWN to get back to bootloader.
(you may need to try 2 or 3 times to get it right)​
the important part is when the phone reboots, let go of POWER but keep holding VOLDOWN

I'm not really "waiting" for any lights. Right now it's turned off since the battery ran out a while ago.
What I do is that I:
-Plug it to the wall charger or computer.
-It turns on, on his own.
-But as soons as it tries, yes, I am pressing the Power+ Volume Down and never let it go.
-I also tried to, when the screen is the HTC's logo screen, hold Power + Volume Down until the screen went black, then I'd release the Power button leaving only the Volume Down in hold, didn't work either.

Oh... yes, I've heard about the "bright light" to the sensor thing. I can tell also that it actually works.
If you hold the power button with the phone in front of a very bright light, you press power button, and no matter what the problem is it would actually turn off after some time. I did it and it worked, as in, it turned off.
But I've already tried pressing Power + Volume Down with the phone already turned off (having enough battery of course), but it didn't really work either, it just went into the same bootloop again.
I'd say it is that since I turned it off while in "stock Recovery" it was in the middle of something, as soon as the phone boots, it tries to boot in recovery, but it's giving me a some kind of error though, which causes it to reboot.
Back to trying a solution, since the phone is off but charged now, I'll try turning it on with Power + Volume Down WHILE I stuck it into a light bulb or something. Could some one please tell me too where is the "sensor" of this thing is located? I don't really know where am I supposed to be facing the phone, if back, or front, or side to the light.

2 little dots on the left front top, opposite the camera, if you have another phone available to you, use the flashlight on it, that's plenty bright enough at close range.

Did just that, right at those two little spots,but now the trick's not working, even though it had before, only I'm not sure if it was flashing to the two-little-spots.
Phone was charged and off. I turned it on holding Power+ Volume Down, with the phone's two spots facing straight to the flashlight.
It went straight into the bootloop still.
Are you sure it is there, and not right in the front or back camera?
Is it bricked?
So I decided to go running with my phone today in the morning. I used an old nike armband for iPhone, so nearly half of the phone was exposed to my arm. When I took it off, the exposed part of the phone, was sweaty, so I dried it off with my t shirt. The phone had a black screen. I tried to press and hold the power button until the phone rebooted, but all I got was a static screen for about one second. Afterwards, neither the screen nor button lights or LED indicator worked. I tried connecting the phone to the PC but nothing happened. It's an unlocked at&t HTC One m7 bought factory refurbished on ebay, running ViperOne custom ROM.

Well, unlike your case, my phone was actually 99.9% clean since I fixed it with the RUU. I don't think there's a ROM related issue with these reboots my phone has now.
Problem: Turned phone off while it was doing something inside stock's Recovery. Now got caught in an infinite reboot because of that,
It is actually something like this.

Just that mine is HTC One, and, well, besides from that screen it's also rebooting on his own every 8-10 seconds.
When you say you "turned it off" after selecting recovery, how did you do it?
I don't think that interrupting recovery when it's starting up ought to do anything.
Were you able to boot properly and use the phone after running the RUU?
My gut feeling is that there is some vestige of non-Verizon software on it gumming things up somehow.
You don't actually need to hold vol-down while pressing power. It will work just as well holding power until it stops blinking and then pressing vol-down as soon as the screen goes black. But you're saying that holding power down does nothing at all? It's just stuck in a continuous bootloop?
Have you tried seeing if it shows up in ADB?

Just as it sounds. I pressed down the power button to turn it off while Recovery was starting, and soon after that, the infinite bootloop started.
The RUU was 100% good, and I tested everything I could before trying to flash a ROM again.
But, just in case, it was this one:

Anyway, as I said, after I checked everything around the phone, I went to bootloader, clicked recovery by accident, and on reflex turned it off pressing down the power button.
Since then, there's been an infinite bootloop, rebooting every 8 to 10 seconds.
Sadly, and I guess it's because it was freshly flashed from a RUU, I can't access through ADB either.

Since it's powering on, your phone should be fixable, but that doesn't mean it's going to be easy.
I think the reason you're getting this bootloop is that it's trying to get into recovery--trying to complete the command you started--but something is preventing recovery from starting up. You likely did corrupt something by hard-rebooting in the middle of the process.
Fixing it will likely require some advanced methods in Linux. There is an unbricking thread in General--I would check in there for help.

I've been trying to do this for days on my own (couldn't get help) but I finally managed to install a Unbuntu and run the sudo ./revive.sh

HTC Unbricking Project M7_UL 0.6beta
Detecting bricked device..
Device can't be found, check connections. Aborting
The phone is actually connected to an USB 2.0 port, rebooting on his own still, but connected.
It's not detecting it though.

Possible brick after updating twrp

Dear all,
I was on beyond 5.3 with twrp 3.3.1.7 and I wanted to update everything. Magisk, root etc was working fine.
I downloaded the patched twrp file from the beyond telegram chat and flashed it as image into the recovery partition.
The installation was finished in 2 seconds, but stupid me chose to power off instead of rebooting the recovery.
So I tried to enter recovery using the button combo but nothing happened and I was stuck with the samsung logo.
The current status is that my phone only shows the samsung logo.
Holding the power button for a minute doesn't do anything.
Pressing the button combo for recovery mode doesn't do anything.
Pressing the button combo for dl mode makes the phone reboot. It vibrates for a sec, then the samsung logo shows again.
If I keep pressing all 3 buttons the phone keeps on rebooting and vibrating each time, but dl mode never appears. If I let go of the power button the logo stays and again, nothing happens.
So basically I can't enter dl mode nor reboot.
Should I let it run dry and try again or just throw out of the window immediately? :crying:
I let the battery drain over night. Phone was finally off.
So when I plug it in, the Samsung Logo appears and doesn't change. It just stays like that forever until the battery drains.
Pressing the power button doesn't do anything, no matter how long. It doesn't reboot nor does the logo disappear.
Pressing vol+, bixby and power again does nothing.
Vol-, bixby and power makes the phone reboot. The screen turns black, the phone vibrates shortly, the logo reappears. If I keep pressing the buttons the phone reboots again, and again, and again, mever reaching download mode.
If I let go of the power button and keep pressing vol- and bixby the phone stays black and won't even show the logo. Nothing happens. If I let go of either of the two buttons the logo appears again.
It won't boot, won't go into recovery or go into dl mode.
I'm doing all this while it's plugged into the usb port of my pc, and it doesn't get recognized. Samsung 300k tool doesn't recognize it either.
Now I know the meaning of "bricked" lmao.
Does anyone know how to possibly fix this?
Pressing only the power button for a minute literally does nothing. Like hell, how is that even possible?
You can try this to go to download mode:
Vol down + bixby + usb cable connect to PC
It's advisable to charge battery first before flashing firmware.

I tried that for like a thousand times already but now it chose to magically work somehow.
I think I peed myself a little when that ugly turquoise screen appeared and I screamed from sheer happyness.
THANK you!!!
The problem that doesn't stop giving lmao.
Got into DL mode, got odin to start, but after like 10 seconds my phone dies and odin fails.
Now I cant get into DL mode, but rather only the "an error occurred while updating the device software. use the emergency recovery function in the smart switch pc software."
Could it be the battery that simply dies?

Yes most probably a discharged battery. Hopefully you can go to DL mode again after charging your phone.
hello,
I've and S10e and because an important app to me I need to go back to android 9 where it works.
I've read a lot info about downgrade, but no one says ROOT/UNBRICK.
Can someone inform if there is a way of downgrade without ROOT (maintaining the warranty).
thanks in advance
P.S.: Maybe too naive question, sorry for that
