[Q] Question: Failed to flash boot.img, possibly bricked incredible s?

I was flashing on MIUI V4 and was following the instructions. it instructed me to flash on the boot.img after flashing the rom
i proceeded to do so, but the boot.img failed to boot. i had to go do something so i powered my phone off from the bootloader. after that my phone would not turn on at all and the charging light would not turn on while charging. From what i understand the boot.img contains the kernel and the ramdisk? and correct me if i am wrong, but even without a kernel or ramdisk i should be able to boot into recovery or bootloader at least right?
EDIT: yeah thanks guys lol. i just left the battery out for a good minute and it booted back into life, cheers for helping.

Yes you should be able to boot into recovery and bootloader as it doesn't even require an installed boot.img. Only the rom relies on the boot.img to boot up.

If you flashed that kernel it already has recovery implemented.
I suggest you flash a stock ftf for your phone from the all in one thread (First thread in the Q&A section) then start again. No need to unlock again, just flash the kernel and then enter recovery and flash your choice of rom
EDIT
If you flash recovery over fastboot then you all you will ever do is enter recovery because you have flashed it to boot. If you flash something in fastboot then thats how your device will boot.

Thank you for your fast reply!!!
The only thing why i want to get in fastboot is to flash Version 3 of this kernel "Advanced Stock Kernel V5 with Cwm. Init.d support and root package" but i don´t find it as an zip file.

kernel's have to be flashed in fastboot. (Why would you flash siyah kernel just to flash this kernel?)
Once you have unlocked the bootloader just flash the kernel of your choice. IMHO siyah kernel is the best for xperia T currently (Including my kernel).
So as i said, flash a stock ftf for your phone, then just flash the kernel of your choice.

[Q] my 4x HD won't boot after flashing insecure boot.img

OK I used this tool found herehttp://forum.xda-developers.com/showthread.php?t=2230934 to unlock and root my optimus 4x, it successfully flashed superuser but wouldnt unlock my boot loader, it brought up the screen to continue to unlock and press volume up but it got stuck on that screen for 45 minutes , I flashed twrp recovery but it wouldnt boot to recovery so I reflashed stock recovery,so I thought it would be a good idea to flash an insecure boot image,now my phone won't boot to recovery or boot at all , I just get error;boot image signature,any ideas guys,I only have the phone a day.

You have to unlock your bootloader before flashing recovery or unsecure boot. Look here: http://forum.xda-developers.com/showthread.php?t=2224020

Redmi 4X bootloop after installing TWRP?

Hi,
I'm having a bit of trouble. I had a brand new Redmi 4X, and I was advised to install TWRP, root it, and install the Xiaomi.eu rom until LineageOS is released. I unlocked the bootloader, flashed TWRP, managed to get into it once and now I can't do it again. When TWRP loaded it asked me for a password for decryption but it let me just skip it it seems (not sure if that is the problem) but now I can't boot normally, I can't boot into recovery, but fastboot seems to work okay. How do I go about fixing this?
I've tried reflashing TWRP but I still can't get to it, and I don't really know enough about this stuff to know where I've gone wrong.
UPDATE - I think this is to do with dm-verity and having the stock kernel installed. Now it's too late to undo what I've already done, so I hope to god that someone knows how to fix this.
UPDATE - Right, the problem is solved I think. I had to do an awful lot of googling, and I'm not entirely sure what it was specifically that fixed it. But I found a guide that taught me the fastboot command "fastboot boot twrp.img" which saved the day. Even when my phone wouldn't let me into recovery, it allowed me to flash a no-verity.zip which i think is what allowed me to boot, and it allowed me to flash superSU.zip and then the ROM I was aiming for. And now I've booted into the ROM successfully and hopefully I am rooted and all is well. Plus I can access TWRP as normal now.
Any help would be greatly appreciated

Can you boot into TWRP by pressing the buttons so that you boot directly to TWRP??
Have you tried Command Prompt to boot with commands in to recovery??
And if you get into TWRP you should have everything on the SDCard and then just
format all things except SDCard and then flash from SDCard everything
That is what I would try..and yes it ask for a password but just skip it to get to it
If you can get into TWRP to flash from SDCard then you good to go..if not
Google all the commands for CMD..and plug your phone to the PC and flash everything with the
commands.....
Let us know what is working and what not and what steps exectly you are doing
EDIT
Turn off your device > Press and hold “Power” and “Volume +” buttons at the same time.
After short vibration signal release the power button and wait for TWRP to start.
To boot in stock recovery open “Update” app.
In the setting select “Boot in recovery”.

Thanks for the reply. I can't get into TWRP. Even if I could get into TWRP how would I get files on the phone to flash them?
Is it possible to flash any rom from the pc directly and if it is will this possibly help? I think it's not booting because the kernel is still stock.
I'm not sure what you mean in the edit, how do I boot into stock recovery without being able to boot the phone (and when I have already flashed TWRP)?

Hey, I have exactly the same problem. Latest stock rom, flashed twrp in fastboot and got into the boot loop. Nothing works. I can only enter fastboot. What exactly did you do then? What is this no-verity.zip? I can't find anything about it.

I had a problem
I unlocked bootloader then installed redwolf recovery and took a nandroid backup. After that i rebooted to system but stuck into bootloop, could not boot to recovery, could not boot into system, So the only thing worked was that i flashed fastboot rom with mi flasher. And syccessfully rebooted to system with bootloader locked and stock recovery. So, if anyone have same problem you can do the same. How do i install recovery safely again? Should i use TWRP only? Should i flash v3.1.0 with lazy flasher or v3.2 directly without lazy flasher? I don't want to stuck into bootloader again, have to get all data deleted.

Fix boot

So I was restoring the stock boot image so I could flash magisk, and I ran into a bit of a problem. I tried booting it up after flashing, and it's stuck on the boot screen so I'm assuming I flashed a bad boot. This wouldn't normally be a problem, except that my volume up button doesnt work meaning I can't boot back into recovery mode/bootloader. Is there a way to get to the bootloader or recovery screen without using the volume up button?

I think you might have accidentally flashed the stock boot image to your recovery. Have you checked the option to flash the boot image and not recovery?

I'm pretty sure I flashed to boot, I can turn it on and it just shows the blu logo. Before I had a custom boot image though and it's not showing that anymore though.

I'm assuming that custom boot image came prerooted right? You might need to flash the rom that came with the custom image to boot. An easier way to get Magisk which I've done is to flash rom, then flash the unSU zip to remove traces of root then you can flash Magisk like normal.

I would do that, except with the volume up button broken I'm unable to get to recovery mode, and without being able to boot into the system I can't use adb
