[Q] S On Unlocked Dinc2 stuck at HTC screen

I am a noob, I have made several mistakes.....but I am literally begging for help.
I unlocked my Dinc2 through the HTC dev site....I know now this was mistake #1. I tired flashing a few roms, none of them worked....they all got hung up on white HTC screen. I was able to get into recovery and get back to my stock rom before I tried installing anything.
The last rom I tired, I tired doing it through adb and command prompt...it looked like it worked, but when I booted...it got stuck again. I tired recovery and this time the restore wont even boot.
I have read all the posts similar, and the only difference is I am S On so I cant flash a RUU.....please help.
I have taken so many pieces of advice I dont know what to do, thank you in advance.

When you flash a custom ROM on an locked bootloader, you then extract the boot.img contained in the ROM's zip file and flash it in fastboot mode using the command:
fastboot flash boot boot.img

I may have extracted the wrong boot.img..... if I try this over again and get the right one should it work?

Yes that is the procedure you need to do with the unlocked bootloader.

[CLOSED] Phone won't boot. Stuck at logo

Trying to check different AOSP ROMs to find the one with minimal a random reboot issue.
At first it was fine but then when I flashed some more and rebooted it would just show the LG logo over and over.
So I reflashed and after a while the flashing would be in progress and the phone would reboot to the LG logo which flashes over and over.
I am not able to proceed. I have tried several different ROMs with the same result.
I can boot into recovery just fine but each time it asks me if i want to reset. If I press yes it enters recovery mode.
Anybody knows what might be causing this?
Should I go back to stock via KDZ method?
I have a D855 32 GB international version
I reverted back to stock via kdz method which was successful but it's still happening!

Thats normal when it asks to reset i would still do the kdz method somethin till aint rite

I tried flashing once more and it didn't reboot mid-flash.
However, it still won't boot correctly, gets stuck at LG logo (which blinks over and over)
Could it be a kernel issue?

Tried with 3 different ROMs and it's the same.
I flashed only ROM and nothing else this time. Instead of rebooting into system from recovery I powered it off then powered on using hardware key. I saw the ROM's bootanimation for a second and then it got cut off and back to the LG logo.
I don't understand :/

Now i used to have a prob with my g2 when i flash a rom it bootloop if u have a good twrp back up try flashing rom then restoring only the boot image no system or cache just boot

Unfortunately I did not have a backup. I thought maybe the ROM files got corrupted so I copied them again and the flash was successful.
I thought okay great and flashed gapps. Aaaaand it happened again.
So i went back to stock. But it's still happening !!!! The phone won't boot at all. Just flashes the logo

Just for kicks try downloading ure kdz again sometimes they can download corrupted and still flash to the fone

Apparently it was an issue with the battery (says the service center).
So put in the new battery and seems to boot fine
Thanks so much for your help!

Your welcome

Still No solution for d855 boot loop?

Yea his battery

After successful (?) upgrade to MM, can't boot past Verizon screen.

I was on 13B rooted, then flashed the stock system to return to unroot status. Everything worked fine. Plugged into computer and Verizon Upgrade Assistant suggested upgrade to 13C, so I bit. After a 4 hour (!) download of a 2 Gb file, the upgrade install proceeded without incident, and resulted in a successful completion according to the Assistant. Phone started booting and the Upgrade Assistant re-read the phone as being on 13C, but, the phone stalls and refuses to boot past the Verizon red splash screen. I have pulled battery and tried numerous times to boot, with no luck. It just sticks at the same spot.
Any suggestions? I'm nervous about re-flashing 13 B for fear of bricking it, so perhaps flash 13C kdz?
Thanks in advance for any help.

I have now tried flashing the 13C kdz unsuccessfully a number of times. I verified the checksum on the downloaded kdz file, and attempted to flash it on three separate computers where I had successfully flashed the G4 in the past. Each time that I tried flashing the 13C it reads: "Required Information cannot be found. Contact the system administrator."
I am still stuck here. Even in the flash tool, the phone is read as having 13C on it, but it still will not boot past the Verizon splash screen. Any thoughts on whether I should dare try flashing 13B, or would I end up with even more of a brick then I have now?
Thanks again.

DO NOT FLASH 13B!
Isn't Android 6 24c?
I got stuck on the Verizon screen, but a wipe fixed it at that point.

Thanks, and you are correct on the number, MM is 24C.
May I ask, how were you able to wipe when stuck on the Verizon splash screen? I would love to do that if possible.
Thanks again.

Hold volume down and power on if I remember correctly to put the phone in recovery mode. From there you can choose to do a wipe/factory reset.
I had issues with way long boot times, the wipe fixed that, but then apps kept FC. I ended up downloading the KDZ file and used the flash tool to reflash 24C. Everything is stellar now.

Thank you so much, mikeewhite! I followed your instructions and they worked perfectly, so I am back up and running. You are the reason that I love this list so much, as there are so many people like you generous with their time and advice.

xperia play bricked? pls help

hi all im hoping u can help me i have an xperia play which i tryed to root using cynogen mod 12 but it fails on install it will then reboot and show the blue cynogen logo but sit thier untill battery pull. i can access cyonogen recovery but thats all. ive tried installing other roms such as 9, 10 and 11 but all do the same thing (although 11 does seam to install/unpack).
i unlocked the bootloader and rooted the phone successfully. i also used flashtool to flash the boot.img.
i have heard i could fix the problem by sideloading another better recovery tool but i dont know how to do that. as off now im stuck in cynogen recovery.
any advice you could give would be greatfully appreciated, at this point im completely out of ideas and if you need anymore info i would be happy to provide it
thanks in advance

Hi,
It would be nice if you linked the exact ROM you tried to flash on you phone. It sounds like the boot.img is incorrect.
You can try flashing this kernel forum.xda-developers.com/showthread.php?t=1804003 . This one is for ICs roms(4.0.x).
Or this one - for Jelly Bean versions(4.1-4.2) - forum.xda-developers.com/showthread.php?t=1861970 .
All you have to do, is boot into fasboot mode and flash the given .img file as boot.img. (The difference between 480p and 720p kernels, are that 480 can't capture 720p videos, but sometimes 720p kernel doesn't work with all roms).

hi tnx for the help the rom i tried to install was cm-12-20150314-UNOFFICIAL-LegacyXperia-zeus
i think your idea would work but im unable to boot into fastboot mode as i used flashtool before and it doesnt recognise my phone anymore ( i dont know if i can use ADB as that option is available on my boot loader)
if you could provide me with a link to how to flash a new .img/rom using another way other than flash tools that would be really helpful. im sry to be such a noob, i have rooted every phone i had and never encountered this problem before and am completely stuck.
tnx again for your help

ok ignore my last msg i managed to flash the .img in fastboot no problem but now it wont let me into recovery mode so i think im stuck in some infinate boot loop no matter how many times i click volume down it just reboots after about 2 mins, anything i can do about that or am i now really bricked?
tnx again for your help

Well you could try to return to point zero by flashing your phone to stock rom and try to begin from there.
You can do that by using flashtool and downloading stock ROM from these forums.
BTW, you can enter flash mode by inserting usb cable and holding search button(i think, you can try other buttons). Your LED has to turn green, blue is fast boot.
Also if your flashtool give you errors, download earlier version (see some other threads about flashtool, there are links to older version). Maybe it doesn't recognize your phone, because of the new version, i've had problems with it too, but i had to download old version and everything started to work as expected.

nexus 5x stuck in bootlooop and unable to fix

hi, so i'm not going to even start how much trouble this bootlop caused me.
it happened overnight so my alarm did not go off and i came late a work,...
i searched for 5 hours straight, downloaded more than 5gb .img files and twrp versions.
i even tried lineage os but nothing is working
until i stumbled upon this guide -> https://www.xda-developers.com/nexus-5x-bootloop-fix-boot-phone/
i download the img file used adb to flash it and now the phone is stuck on the google logo.
before this my phone would go on and off and showing a warning that my bootloader is unlocked now its just stuck.
i installed different versions of bullhead and still had no success.
if there is anyone with the same problem and found a solution please lord show him this thread so he can help me.
thank you in advance.

Probably the boot loop of death.
Check this post: https://forum.xda-developers.com/nexus-5x/general/tool-bootloop-death-blod-workaround-t3819497
Since you already have your bootloader unlocked, you should just have to flash the BLOD 4 cores fix zip.
I'd you've needed up your phone, flash the latest Google image (flash-all) then the BLOD 4 cores fix before the phone restarts into the OS.
