[Q] Accidentally uninstalled OS and Relocked Bootloader, help?

So as the title says, while attempting to restore my phone back to stock i relocked my bootloader and deleted my OS. My phone is currently S-OFF and has TWRP installed. I have attempted almost everything trying to unlock my bootloader again. When i use my "Unlock_code.bin" it says successful but nothing happens my HBOOT still says that it is relocked. I'm losing my mind trying to figure this out. Can anyone please help me?

Do you know/have your device firmware no. ?
Grab the firmware and flash that to get the stock recovery installed then you can use your unlock_code.bin to unlock bootloader.
Or
Get a pre-rooted ROM.zip and put it in your external_sd and install that.
After all set up, you can unlock bootloader with this guide : http://forum.xda-developers.com/showthread.php?t=2708571
Or
Since you're trying to get back to stock, grab the nandroid backup if there is one from : http://forum.xda-developers.com/showthread.php?t=2701376
then use the external_sd card way to put back stock recovery on your device.
Basic thing is there are many ways to fix your problem ... just pick one of those

Do you happen to know where i can find firmware for my M8 i can't seem to find it.

Did you back up before flashing if so just restore to a point where the boot loader was unlocked.
I'll begin searching for the ROM for your m8?
I need more info first though what's your carrier, what's your manufacturer, and model of phone and the version.
Also need to know current version of android or the os your using

Remove your PIC or edit it not to show the Serial No. and IMEI no.
You can grab the OTA_M8_UL_K44_SENSE60_SECURITY_Rogers_WWE_1.55.631 .4-1.12.631.17_R1_release_366548ar2zyirbo1z4eqie.zip
from here : http://forum.xda-developers.com/showthread.php?t=2694297
then open the OTA.zip with 7-zip and extract out the firmware.zip from it; that's your firmware
OR
Since your device is S-Off ... you can restore and update to the latest one without going back to stock and do OTA.
Just follow what I have here : http://forum.xda-developers.com/showpost.php?p=55398223&postcount=7

For your software version 1.54.401.5 (provided that is your current firmware, means you do have the Intl EU WWE CID), you don't really need S-Off
So... first confirm your what your CID is. If it is EU WWE then ....
Your options :
1. Restore stock ROM 1.54.401.5 then install the matching stock recovery then do multiple OTA up to 3.28.401.6 or 3.28.401.7 whichever is available for your CID. Then reflash custom recovery then you can flash any latest custom Sense ROM that you want. (In any case, you don't need to relock bootloader)
Check this thread : http://forum.xda-developers.com/showthread.php?t=2701376
2. relock bootloader then flash in RUU mode the untouched higher version firmware. But you may need to flash many firmware step by step to follow the increase firmware no. and it's not easy to find all the related untouched firmware and this is a bit complicated for newbies so I suggest you go to option 1.

Sorry for taking your time

You need stock recovery installed for OTA to proceed, no custom recovery.
Check this thread : http://forum.xda-developers.com/showthread.php?t=2701376
Or you can go here and use the sdcard method to install the RUU.

That is because you can't flash a recovery with an relocked bootloader !

It is possible to unlock it with the same unlock code that i received?

Problem solved by re unlocking and flash the stock recovery , it happens that it has custom recovery which i dont
remember when i installed it.
another thing , i remember clearly that Unlocking bootloader require erasing data, but when
i was trying to unlock after the first page of unlocking process, it took me to the recovery , and it is done
and no thing erased.

[Q] please help..no os or root

a friend rooted my phone tellng me how good it is and now he says hes wiped the os and root off so if anyone can help i would be gratefull

I have tried tried to find the right ruu and use all in one tools but it says 12 signiture verification error

please. if you could point me in the right direction

Okay, I'll do my best to guide you through this. We'll start with the unlock.bin that would have been obtained through the HTC developers website. Do you have it?

Did you relock the bootloader (this is required to RUU if s-on)?
If you did, than its not the right RUU.
Restore the nandroid if available (and this should always be the first thing that is done after installing custom recovery).
Another approach, if the bootloader is still unlocked, is to put a ROM on a removable SD card (using a computer and card reader), insert into the phone, and just flash the ROM from TWRP.
What CID?
What hboot number?
S-on or s-off?

my cid is 02-001 and i tried loads of ruu's but signiture fail

relocked
hboot / 3.16.0.0000
s-on

You need to re unlock the bootloader, install proper TWRP, restore stock 1.54.206.10 backup and install its stock recovery and do OTA to the latest before you can install most of the Sense based custom ROM on XDA.
Give me a few minutes, I'll put up link to download the backup in this thread :

You can't just run any RUU. The RUU needs to match your CID. I don't think O2 has RUUs. So you can run RUUs until the world ends, and they still won't work.
Basd on that, I suggest following the previous comment to unlock the bootloader again. From there, flash TWRP, then flash a ROM or stock nandroid (either put it on a removable SD or use adb push).

It's not easy to find a ROM for hboot 3.16.0000, there are some but it's bit tricky to find one. Maybe someone else can help you with custom ROM.
I can only help with TWRP backup - and I already put up link in the thread that I gave earlier.
So it's up to you how you want it.

Try a 4.4.2 ROM (there are a couple in the Development section - but as mentioned not many). You'll have trouble with anything newer, due to outdated firmware (hboot, etc.).

What you can try :
Install TWRP 2.8.7.0, make a backup of your current ROM
Restore 4.18.720.8 backup and 4.18.720.8 stock recovery then do OTA to 4.18.720.10

Will i be able to restore 4.18.720.8 backup on 4.18.720.10??
Also i'm not able to downlaod from mega.co.nz. Can you provide me any alternate download link?

Are you in India ? You need to use VPN to download because ISP in India block Mega site.

Well thank you for fast reply sir. I am in india but that's not a problem. The PC does'nt download from mega site and the file is too large to download through phone.
One more thing, I have 3.35.720.1 recovery image (14.22MB)...
If i downloaded the third file from this list; androidfilehost.com/?w=files&flid=24511. Can i do something then.. the CID is also HTC_038.
If i can, then how? Using above steps you provided or something else?

No, 3.35.720.1 won't work for OTA because that's more than one version lower than your current one.
You only can use either 4.18.720.8 or 4.18.720.10
Try to contact 4.18.720.8 backup owner and see whether he can help you.
Also ask him whether he has 4.18.720.10 backup (I believe he has one).
If there is one, use 4.18.720.10 instead of 4.18.720.8

I got it
Hey friend, first of all i'd like to thank you for all your help. i think i got it back to Stock but not sure though.
I re-locked the bootloader then using PC i installed
RUU_M8_UHL_L50_SENSE60_MR_hTC_Asia_India_4.18.720.8_Radio_1.24.21331147A1.09G_20.68.4196.01_F_release_417228_signed.exe and when the phone rebooted.. i didn't find Super SU and when i rebooted into bootloader, i saw this:
Software Status: Official
RELOCKED
however my software is now 4.18.720.8 instead of 4.18.720.10 but that's no problem at all.
Now you tell me,
am i back to Stock?
is my phone unrooted now?
how can i install the latest update, using software update or do i have to find the RUU for that?
How do i myself take a stock backup since TWRP is removed.

1. Yes but one version lower
2. Yes
3. Settings - about - software update
4. Unlock bootloader with your unlock_code.bin that you got from htcdev then install TWRP 2.8.7.0
then do backup

if i unlocked bootloader, wouldn't that make the software modified or phone rooted?
And the backup which i will take, will that be a Stock Backup i.e fully unrooted, official software, etc
Also how can i take stock recovery backup? i mean recovery.img

unlocked bootloader - software modified, yes. Phone rooted, no. Root or not to root is your choice nothing to do with unlock bootloader.
If a backup made before you root the phone, yes that will be unrooted official software stock backup (just like those you can see in my thread - http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860)
When you do OTA, before install OTA, copy the OTA zip from internal storage/downloads folder to PC. Open it with 7-zip, open firmware.zip then extract out recovery.img - this is the stock recovery.img (that's how I get all the recovery.img in my thread - http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860)
You already managed to get back to stock after you spent a week to find how to do it ... so anything further that you need to know, all the info are available on xda like how to unlock, how to root, how to backup & etc .. just use the search function, you'll get the info. The same way how I gave you links .. I use the search function. I believe you can do this on your own.
Good luck.
