Soft Bricked M8 in need of help badly

[tartansteve]

Hi there in need of some help. I have really ****ed up my install of twrp and supersu from my htc one m8.

I followed this person tutorial htconeroot com/htc-one-root I followed everything to the letter apart from enabling Dev enable usb debugging.

1st of all I downloaded this twrp file "openrecovery-twrp-2.7.0.2-m8" when I should have downloaded the latest version of twrp. Such a noob mistake I know now : (

2nd I also downloaded a older version of supersu SuperSU-v2.79-201612051815 which I loaded onto my phone and should have downlaoded the latest version.

I followed all the instruction on the video and when I rebooted after instaling supersu my device is now stuck on the HTC startup screen.

I tried to reboot again going into fastboot and recovery and nothing worked. I know I should have just updated supersu to the latest version but I followed some other peoples advice and now I have completelty screwd my phone I think.

I deleted supersu from twrp and wiped the files as well. My computer now does not recognise my phone folder to be able to install any updated version of supersu or install a ROM. My computer OS is windows 10 and it now sees my phone as a cd drive so cannot install anything on the drive at all.

I can get into twrp but nothing seems to work when I try to reset back to factory settings.

Is there a command line way in geting back into my phone and being able to sort this mess that I have made.

In need of some serious help from the experts here at xda developers.

All help is very much appreciated.

Thanks Steve

These random "root" websites just copy content from XDA, and have little or no community to help you. All you need is on XDA, so I recommend stick to XDA.

Such "root" websites also don't give enough information, aren't well organized, and don't update it all. So they are very likely to get you into trouble, as you now know.

2nd I also downloaded a older version of supersu SuperSU-v2.79-201612051815 which I loaded onto my phone and should have downlaoded the latest version.

What version, if it wasn't SuperSU 2.79?

What version of Android was the phone on when you started? Was it Marshmallow?

I can get into twrp but nothing seems to work when I try to reset back to factory settings.

There is really no such thing as "reset back to factory settings" especially in TWRP. Just going in and wiping things, isn't going to fix the problem.

Try to fastboot flash an updated version of TWRP. If you were on Marshmallow, try current version 3.1.0-0 from there: https://dl.twrp.me/m8/

Once booted into TWRP, see if you can access the internal storage from your PC. If not, make sure internal storage is checked in "Mount".

Sorry was this version SuperSU-v2.37.zip. I do appologise thats the latest version that I posted and was ment to be this version SuperSU-v2.37.zip this is the one that I installed.

Yes it was marshmallow.

I downloaded the latest version of twrp and can I ask how to re install twrp ??

I cannot access my phone internal storage for some reason my computer is not recognising my phone now. It was before as I installed supersu straight onto my phone internal storage and tried to boot the phone from that. It's now coming up as a cd drive and I cannot access to install anything on it.

In mount all I have
System >>> not checked
cache >>> not checked
Data >>> is checked
Micro SDcard >> is checked
USB-OTG >>> not checked

Thanks again for your help

Steve

Flash with fastboot. Which I would assume is the same way you did it before. Instructions on TWRP's website: https://twrp.me/devices/htconem8gsm.html

I cannot access my phone internal storage for some reason my computer is not recognising my phone now.

Let's get the right version of TWRP on the phone first, and see if that helps. If not, we'll go from there.

Updated twrp

Hi just to let you know that I have booted into the new twrp. I am using FWUL and using simple-ADB and it installed it no problem.
Just cannot seem to find how to install supersu onto my device as my phone is not showing up FWUL OS.

 

[redpoint73]

Sorry, what is FWUL?

Updatefor you

Hi just to say that I installed supersu as well the latest version SuperSU-v2.79-201612051815. After rebooting I am back to the htc page. I have no ROM installed at all on this and it's saying there no OS installed on my phone.
I want to install kali Linux Nethunter and I have downlaod the correct files to install.
WillI have to install another OS like Marshmallow or kitkat before installing Kali Nethunter.

Thanks again for yourhelp : ))

Did you not send me there to download it lol : ))

You must have at some point in trying to "fix" the problem, wiped system in TWRP. System is same as ROM/OS. So if you wiped it, it's pretty obvious that no ROM is the result.

Flashing old SuperSU in itself doesn't result in no ROM/no OS. It just makes the phone stuck on boot screen, and flashing the proper SuperSU will fix it.

WillI have to install another OS like Marshmallow or kitkat before installing Kali Nethunter.

I've never used it. But reading the thread, it looks like you need a fully working OS. So pick a ROM, put it on the phone, and flash it. Then flash Kali Nethunter.

Ah, I see it's listed as one of the several options for adb/fastboot in the TWRP install instructions. I've never used that specific one, so the acronym confused me. Any fastboot/adb environment will work about the same. You didn't really need to install anything new on your computer. You already had fastboot on your computer to begin with (to unlock the bootloader), and that would have worked fine to install TWRP.

BackUp File

Hi there and thanks very much for your help very much appreciated. Before I did everything I made a back up and have the files on my desktop they are:
0C77AEECE8C258113148C6FB487946BF97B34672
01C669ECF50A775226B15B9F60EEB522AB34BE2F
I have ten of these files and a deafault file as well. Can I restore these to my hpne at all.

I am going to try and install marshmallow on my phone as that was the last OS that I had. Do I have to have the most current and updated version MM.

What did you use to "backup" the phone? Those don't look like TWRP backup folder names. They look like MD5 verification codes?

Individual TWRP backup folders will usually have name format of the date/time the backup was made, such as: 2017-04-22-20-43-56....

I am going to try and install marshmallow on my phone as that was the last OS that I had. Do I have to have the most current and updated version MM.

There weren't many different official versions (maybe 1 or 2) of Marshmallow for each M8 carrier version. Any version MM should do.

"locked s-on" cant get to unlock and also stuck

You may have outdated firmware and outdated TWRP version. Most of current ROM won't get installed on outdated TWRP.

Post fastboot getvar all result without serial & imei no. We'll see what you need.
