Help with my rooted HTC M9 on custom ROM - One (M9) Q&A, Help & Troubleshooting

Hi everyone,
So I installed android revolution mod and everything was working fine. A few days ago my phone rebooted and when I tried to unlock it it looked like the phone went to factory reset. (I don't know how)
Now after trying to get everything working I went to recovery and deleted everything and now I'm stuck in bootloop. I haven't made a backup of stock rom. I even relocked my bootloader.
My phone is Europe M9 on Vipnet (but they say the phone is unlocked). How can I revert things and install other rom or go back to custom?
Thanks in advance for your help

Please read the ReadMe thread.

[Q] Can't S-off because of bootloop

Hi,
I've always been using CyanogenMod11 on my HTC One M8 since the day I got it.
But recently I wasn't fully satisfied with it so I wanted to flash a new ROM and simultaneously upgrade to Lollipop. I really didn't want to use HTC Sense so I figured that SkyDragon Google Play Edition would be a good option. I read through the whole post and flashed Philz Touch 6.25.5 since it was the recommended recovery.
The first boot took pretty long but seemed fine. But during the setup I realized the Wi-Fi is not working. Since I read in the F.A.Q. of SkyDragon that that's a common issue I guessed it wouldn't be much trouble.
Now, sadly, I did not make a backup of my completely stock HTC One M8 so I couldn't just update to the latest OTA. So I tried to S-off it but the compatibility-tests of SunShine said the ROM has to be closer to stock. Then I flashed the storc ROM from here and ran SunShine again, this time with positive results. But when it had to restart the phone during the process of S-off'ing it got stuck in a bootloop. Wiping cache and dalvik did nothing, only completely flashing a ROM again did.
Now everytime I flash a ROM the initial boot works but from then I can't just reboot because I always get stuck in a bootloop.
So, I got SkyDragon and it seems to be working just fine, except for the Wi-Fi, the bootloops and I still don't have S-off. I guess that fixing the bootloop might be the first step so I can S-off and manually flash the latest GPE L firmware.

You know you can RUU right??? That'll get you back to stock, and upgrade to the latest version.
Your first problem with WiFi was possibly because you needed to update your Firmware.
Just get the latest Lollipop FW and flash through fastboot. As the above guy mentioned, that'll more than likely fix your wifi issues. If you get the Lolli FW with Hboot/stock recovery then you'll lose all your data and recovery but you can reflash that easily. Try to find one without Hboot/stock recovery and you'll be good to go.
Why everyone is replying to OP that 2 & 1/2 months old ? OP was the first post and he never come back to XDA to post further

Hope I haven't bricked my HTC M8 yet. Need help.

I was trying to install custom rom on my unlocked HTC One M8 and I probably messed up somewhere along the way.
My phone is rooted and S-off. Its got twrp version 2.7.0.2 (if it matters).
I was trying to install skydragon gpe ROM.
This is how my process went : First I backed up my current rom on an SD card (The HTC version with sense and lollipop) and did a factory reset on my phone and tried to install Skydragon for M8.
Soon as I started the process, it said install failed. This is the image i57.tinypic.com/15h6iq.jpg
I tried another rom. Same thing. Failed. I've tried some 5 or 6 roms so far. Nothing works.
To make things worse, when I restore my previous backup (HTC Sense version), it does go through all the way, says its successful.
But, on reboot, the phone is stuck in the HTC One logo and does not proceed at all.
Now my phone isn't usable at all.
Any suggestion helps.
Please help.
Or you need to update the firmware or you need to update the TWRP ! 2.7 is very old !
How do I update twrp without an OS on the phone.
I'm sorry if this is a dumb question. I'm new to all this.
I tried to update my firmware but all the instructions I found on the web needed an OS installed on the phone.
May be I'm doing it wrong. I have mac to work with or a windows computer with no USB 2.0 ( I only have 3.0 USB). And those instructions say its not 3.0 compatible.
Could someone please post a link that could help me. I tried but could not find one.

It worked!
Finally !!! Don't know how I did it but it worked. I somehow managed to update the twrp recovery (which was what was apparently hindering the OS install in the first place). And then I went ahead and flash my custom rom. And this time it worked flawlessly.
Thanks guys

HTC Desire EYE - Soft bricked -Needs Expert advice

Hi,
First time to post a question. Please, be patient.
Problems:
1. Fast boot goes into AC (no usb, so no connection with the laptop)
2. Camera not working
What I've done:
1. Flashed TWRP 2.8.4
2. Flashed custom ROMs with no back up (stupid I know)
3. Flashed the Beatmod ROM, then tried to go back to custom ROMs last was [OTA ZIP+TWRP] HTC Desire Eye 2.19.401.1 STOCK Europe 5.0.2 Lollipop, all haven't sorted the issue
3. Flashed the 0PFHIMG firmware, no differece
2 things I've noticed as well while doing these trials: the TWRP says no MD5 file found and when tried to flash crdroid-5.1.1-20151003-eyeul it said your device is M8.
Would really appreciate ur help

HTC one m8 has no OS

Hi,
So i wanted to update my phone to the GPE 6.0 android version, so i followed a tutorial and everything went fine. I had it rooted and turned s-off and used twrp ,but it didnt flash the rom. So by accident i wiped everything and now i have nothing but twrp.
My PC doesnt recognize my phone while in twrp, i can put a file on my sd card like i did with my ROM but everytime i install it , it fails.
I honestly dont know what to do and looked on the internet but nothing matches my problem because i can only use twrp.
Can anyone help me with a step by step tutorial or something. I just want to flash the GPE 6.0 android version on my phone.
EDIT:
I have managed to flash Cyanogenmod on it annd it is working now. still want to get 6.0 GPE version on it. gonna try it and keep this post informed.

HTC one (M8) bootloader locked, wont start up. Tried to install system dump

I am quite the idiot when it comes to custom roms and such, so i apologize in advance for my lack of knowledge. Anyways, I had CM13 for quite some time before this and was using twrp. In my adventures of installing my first custom rom I had thought I needed to re-lock my boot loader, so because of this i no longer has s-off. I used sunshine to achieve s-off in the first place and needed to go back to a stock rom to repeat the process. along with this I had gps problems on my custom rom and had read that i need to go back to stock. I looked on the internet to find a twrp flash able rom, that would do such. (http://forum.xda-developers.com/showthread.php?t=2694994) I was unaware that this would get rid of my custom recovery (again, sorry for my stupidity) and now my screen is stuck on black when I try to boot up the phone, I am incapable of reverting back to my custom rom, and as I noted before, I have a locked boot loader. Everything I have looked for on the internet requires s-off. Is there any possible way re achieve s-off with out a functioning os (I can still access the stock bootloader) or am I just screwed?
Thank You for the help!
P.S. I have the Verizon variant.
Your biggest mistake here is installed wrong ROM on wrong device.
You shouldn't install a GSM stock ROM on a CDMA device, for your case is Verizon.
Search Verizon thread for RUU ..

Thanks for the help! I found an 0PGBIMG for the lollipop Verizon Rom and from there I could reinstall TWRP and then finally a GPE Verizon rom. I really appreciate the response, I didn't really expect one to and I'm glad I could receive your input! :good:
