Unable to boot into flash mode, what could be the cause? - Xperia Z Q&A, Help & Troubleshooting

So my perfectly working Xperia Z, running Resurrection Remix ROM was given for a repair yesterday. The SIM card slot was broken so I got it replace from a third party repair shop.
But after finishing with that, the phone went into a bootloop. Everything was working fine before but now it just doesn't boot. So I thought of flashing stock FTF using flashtool. But even here I am unable to boot into flash mode (Power + vol down button). :crying:
I can go in recovery, I can go in fastboot mode, but not in flash mode.
I even restored a twrp backup but even then it stayed stuck in bootloop.
Can anyone please help me? Why is it happening?

What I thought was right, volume button was broken. Had to replace the flex cable. I request the mod to delete this thread.

[Q] P880 hangs at boot | No S/W update available

Hello,
After rooting my p880, my phone hangs at boot. Just after the boot sound (*pling* ) the phone is hanging. The boot image is still moving.
Things I tried already:
I followed this thread http://forum.xda-developers.com/showthread.php?t=2069723, which tells to do a kdz update. This is not working, as I am not able to get to the S/W upgrade screen. Instead, when I start the phone using the power button + volume down, i get the Android system recovery menu (3e).
I tried to upload a new (cyanogenmod) rom using adb sideload, but that didn't work, as the file I used was damaged (I will retry with new file).
I also did a factory reset and a cache wipe.
Can someone tell me what is best to do?
Kind regards

[Q] Tried installing ROM, phone now cannot boot. Please HELP!

Hi, I sorry to bother anyone, but I need help because my phone is not responding and I don't know what to do.
C6603, rooted, dual recovery installed, bootloader unlocked (I think)
So here's what happened. I very successfully installed the existenz ultimate rom on my phone. It was a wonderful rom and everything was going well. However, I accidentally dropped my phone and needed to send it for repair. Before sending it to the shop, I decided to do a factory reset using the option in recovery mode.
When I got the phone back from the repair shop, I wanted to install the same rom. What I did was download the rom installer and then install the zip file using the recovery mode. I went through the AROMA installer and everything, So I thought everything was going fine. When the phone rebooted, it showed the SONY logo, followed by a permanent black screen. The screen is on, it is just black.
I scoured the xda forums and I tried several things, to no avail:
I cannot enter recovery mode.
My PC cannot recognize my phone.
Flashtool cannot recognize the phone. My phone can't seem to enter flashmode, either.
I tried holding the power button and the vol. up button, and the phone does indeed restart (no vibrations), showing the SONY logo, and then I'm stuck with the black screen again.
I hope somebody can help me!
EDIT: I managed to somehow get flashmode working, so I think my phone is fine now! What a false alarm! In case this ever happens to anyone, what I did was to unplug the phone from any source of charging, then proceed to hold on the power button and vol. up button for REALLY long, I think almost 20 seconds. This managed to switch my phone off (it would keep restarting if I didn't hold in down long enough).
download stock firmware and open flashtool & ready to flash,dont connect until it say.connect your usb cable to ur phone,then reboot ur phone when display goes to black connect ur phone to pc whith pressing vol down ,then flash tool detect ur phone and it flash,sorry foe my bad english

Can't boot to flash mode or recovery mode.

I really need help.
I've got my phone bricked and I can't even boot to flash mode or to recovery mode.
The last thing I've done is boot to twrp and clear data because I am going to change rom. But there is a certain error that pops up. and forgot what was it. After that, I try to flash the rom. But the same error pops up. If I remember correctly. e:ex4ts is not found? Something like that? And now. When I turn on my phone. The xperia logo still pops up. Then after that its only black screen. I tried going to recovery (power + Vol up + vol down) and also tried flash mode but nothing really happens. Its like not being detected. And when I try to charge it. The xperia logo pops up and black screen appears. The charging icon/animation is not popping up. Is there anyway to fix this? Please help. Any help would be much appreciated. Thank you.
Your phone is now bricked and won't boot into recovery.You need to flash stock rom via flashtool to recover your phone.Is that your phone's bootloader Lock?Unable to boot into recovery always happen in locked bootloader phone.
Use Flashtool to flash stock rom. But be careful to connect phone only when prompted. It should boot after that, then you can root phone again and try to install recovery again.
I have unlocked bootloader already. I think there is something wrong with the phone. I can't boot to flash mode and recovery mode. The screen continues to go black light. I've tried for more than 20 times already. But still. I can't go to flash mode. Can I go to flash mode by only connecting my phone to my pc?

use recovery img to flash via flashtool.you'll get your recovery back
Thank you so much for answering my query. I figured it out before reading this. Yes, I forgot how to use flashtool. I forgot how to boot into flash mode. I used the method in Samsung devices (All buttons must be pressed) which technically my mistake. Thanks again.

Please help me I feel so frustrated.

My device is Mi Max 2 today I tried flashing some custom rom which is because yesterday it was normal but it suddenly restarted when I tried booting it up it went to recovery mode btw my recovery mode is TWRP so I tried to just flash a rom again but after its done flashing It keeps booting into TWRP so I was searching online and decided to go back to stock I used the Miflash but after it successfully flashing again This time I can no longer access bootloader my volume up does not work anymore only down and power and im back to stock recovery mode tried accessing MiPcSuite but to still no avail. Please help im seriosly sad like frustrated beacuse I have been trying to find for a fix since yesterday.
Is my volume up broken? is it the reason why I can't access the bootloader. everything went south since yesterday.
I would like to add that the power and the volume buttons where acting funny yeterday when it was doing just fine could it be my volume button but why does it keep booting on TWRP Thinking about it I was getting out of the bath could have damage the volume buttons or something

hey...
is your bootloader still unlocked?
if no... i dont actually have a solution
if yes... you may possibly be okey
you said that you are on stock recovery... and that you can only access fastboot mode(Volume down + Power)
if you can access fastboot mode flash this twrp LINK using "fastboot flash recovery *recovery-name.img* " or "fastboot boot *recovery-name.img*"
then wipe everything... most files would be probably boken! lol.. neva mind!
then flash a rom,lets say this xiaomi.eu's 10.2

i9305 bricked. Vol UP button broken: can't go to DL mode

Hello,
I tried to flash twrp on a stock i9305 through Odin.
It initially seemed unsuccessful (rebooting to stock recovery) until i rooted the phone and flashed twrp again.
From twrp i then tried to flash RR rom but it refused (don't remember detailed message). I decided to give up and reboot.
The phone stays stuck on samsung logo.
I removed the battery. Restarted with 'home+volDown+power'
All i can get is the screen telling me to press VolUP to flash a ROM. My issue is that the VolUP button does not work.
I tried to remove it and press with a pin to no avail.
I can't use adb (not recognized)
Odin sees the phone but can not flash anything as the phone is not in DL mode...
Any ideas ?
Thanks a lot!

I suggest to get a USB jig. I've always one at home. Bought mine on eBay for about 2€. Just search the web.
Thanks. Just looked it up. I'll give it a shot :good:
