I've had some previous experience with custom roms on my old Nexus 6P and thought I would try the same for my mate 9. Unfortunately I've discovered the Mate 9 is not as easy to install custom roms as I thought.
I've tried several things throughout the day and I feel I've accidently overwritten things I shouldn't have but can't remember everything I've done.
It is an Optus branded phone so I believe at the start of the day I had some version of L09C34. I currently have an unlocked boot loader and TWRP installed and would like to flash back to the stock firmware, but seem to be unable to do so. The boot loader is unlocked and when I try flashing extracted parts from fastboot, the phone will reboot, reboot again and sit at erecovery. Unfortunately while I can connect to wifi, no packages are found for recovery.
Additionally I now get this lovely colourful screen in lieu of the logo on initial boot.
Any help would be appreciated.
Okay, so I've managed to unbrick it and install a version of L09C432 and get it working again - thank you to various threads on XDA. I think what I noticed was that someone else had tried the C432 firmware on a C33 model and it worked. Without being able to get hold of the C34 firmware, I tried to flash nougat originally and it worked.
This morning, I've noticed I still have an issue where the touchscreen won't work when the phone is cold (i.e I can't click anything and can't turn alarms off). If I reboot the phone to recovery it's fine, so it leads me to believe its an OS thing. Also, if I give it a few minutes in my pocket, or holding my palm on the screen it then responds. This is the issue I tried to resolve by resetting and trying a different rom but seems I haven't been successful.
Finally, when I first turn the phone on and the screen lights up I see a green background with one blue and one red box. Any ideas what I have messed up there and how to fix it? I'm not too concerned, but it would be a nicety.
Just providing updates in case anyone comes a long with similar issues.
I have now fixed the strange coloured screen on initial power on. I've found the oeminfo for the C432 firmware on another XDA thread and took a backup of what was currently there, restored the C432 version and rebooted. I was presented with the eRecovery and no TWRP. Quick check in fastboot mode showed the phone relocked. I unlocked it again and it booted no issues, however was unsure if the custom rom was still installed as I was presented with the option of an OTA update. Initially my sim card was not recognised, so I had to remove and reinstall it but so far so good.
I've just reflashed my custom rom and will see how I go.
The only potential issue I have outstanding is my touchscreen not working either first thing in the morning, or when the phone is cold - i.e I've gone to the gym and left it sitting in the locker for 2 hours and I can't use the touchscreen when I come back. I can unlock it fine with the finger print reader and the phsyical buttons respond but touches on the screen won't. If the phone is left alone for a few minutes the screen shuts off and turns back on approx every 5 seconds until it becomes responsive. Has anyone seen anything like this before? My googling hasn't lead me to anything helpful.

My Nexus 5 seems to get stuck at the update screen (the standing green android with the spinning polyhedron) after flashing to stock(+unroot) with softbrick/bootloop checked. The flash completed without error. I've left it at this screen for over an hour and not only does it not progress it doesn't even get to the progress bar at the bottom.
This afternoon my (unrooted, bootlocked, stock) N5 turned itself off 3 times while on the charger. Powered back on and then would find it turned off 20 or so minutes later when I checked it again. After the third time it booted to the "Google" screen and would go no further. I tried a hard reset but it gave an error. So I plugged it into my laptop and fired up Wug's NRT, unlocked the bootloader (at which point it got stuck at the same update screen described above for around an hour). I held power till it went off, booted back into bootloader (which showed as unlocked) and performed the flash to stock(+unroot) with softbrick/bootloop checked and ended up at the update animation again. Any thoughts other than RMA?
****Edit: Finally got the phone to boot after fastboot booting twrp. Was able to to wipe the phone (after multiple attemps blocked by can not mount storage/cache/etc/etc errors). Flashed 4.4 and the phone now boots to android BUT radio is non-functional (no signal despite being in my normal coverage area), any attempt to add an APN causes a hard reboot (had to go through all the setup screens again). Additionally, the phone won't turn off, even hard power downs (holding the button for 30 secs) lead to an immediate reboot. Still RMAing but I was able to relock the bootloader.
You really shouldn't RMA a phone after messing it up yourself by using a toolkit when you didn't know what you were doing.
Flash the factory images manually. That should get your phone up and running again.

Performed a manual flash with the exact same results. There is apparently something wrong with the hardware (which may explain why it was turning itself off and then wouldn't boot past the google logo.

Yep, I would agree.
this is my first htc and so far i am missing my samsung and motos
the phone is now completely non responsive and is stalled at the HTC boot screen with the text "this build is for development purposes only " i have the verizon htc one m8 ive tried removing the sd and sim holding power holding volume and power nothing makes a difference.
rooted with s off twrp is my custom recovery
started by putting slimrom on for a change of pace i had horrible signal strength and decided to try another rom somewhere in the process of flashing venom one my sd lost its backups the phone had stayed on the same screen for a while but eventually booted to a stable seeming venom rom and had 3g but no 4g service i ended up rebooting the phone today around 11 am and its been in this loop / screen since. i let the battery die down and was able to get to recovery and searched for my back ups but they were gone i ended up rebooting and now am stuck on the same screen as before. even after trying to enter recovery twrp it goes back to htc and not twrp
i tried every combination of buttons the few times and have drained the battery twice and now it just boots to this screen and is non responsive. hope that i can manage to find a way to push something to it or enter recovery and go back to stock using ruu's
anyone with input or advice would be a blessing at this point id be happy to make a donation for any useful help / anything to get me out of this screen even so i can push another rom or ruu to get me to stock
im afraid ive ruined a perfectly awesome phone
update got back to twrp and tried to re flash the venom one rom after full wipe but used their option for "stock" install said 100% and sucessful but upon the reboot is now seems to be stuck in the same screen.
got into the recover after battery died re flashed venom
after about 15 minutes on the htc screen it went to set up ....still very buggy more so than last time the phone was actually working but it is at least from what i can tell working ... going to try to get back to square one somehow
screen wont turn on and acts very buggy only time it stays on is holding power and gives reboot options... i done f ' ed this phone up.
How long are you waiting after I restarts when the install is finished? It will take a long time on that first boot. I have seen them take more than 5 minutes and if you interrupt it it can cause problems.
Hello guys,
some days ago my phone was permantly booting up in the recovery mode nothing else was possible. As I was on road and couldn't access internet anywhere I just tried to do some wipes, which then made my phone not show anything. I guess the reason that it didn't boot up anymore was that the battery was fully drained. When I was finally back home I was able to charge my phone but then the following happend:
I can start my OPO, see the android logo and then it turns black, but it fully boots up. I mean I can even click the touchscreen and hear some touch reactions/sounds. Also I'm able to turn up/down the volume and hear my phone. Furthermore I'm also able to do the "V-gesture" to turn on the flashlight. When I boot up into fastboot mode I also see the message "fastboot mode" + the little cyanogen face.
All in all everything seems to work, aside that I dont see anything else than dark after the logo.
I tried flashing new roms, stock reset, like seriously anything, but I can't get my phone to work probably again.
Does that mean that my phone got some hardware problems, maybe the touchscreen?
Help is appreciated, thanks in advance!
btw: English isn't my first language, so please excuse any mistakes.
You'll have to try flashing completely stock CM11 rom or CM12 rom, img by img in fastboot..modem, boot, system etc. I helped a friend who had this kind of problem. Probably not the cleanest way, but at least it works.
Already did that 3times using different methods. Stock CM11, CM12 and colorOS
I have a similar problem, did you manage to fix it? And if so, how?
Thanks,
Capelare.
Hey guys,
I have an issue with my Iron Pro, basically I turned off the phone one day, went to turn it back on and the UMI logo showed for 2 or so seconds and the device turned off again. I can access the bootloader but the same issue occurs when selecting recovery. I have tried reflashing the device several times with different roms (custom and stock) using SPFT with no success. However, after leaving the battery unplugged for a long period (3 or 4 days?) of time the device booted so I thought it was all fixed, went to restart and... guess what happened. I can't use fastboot to reflash because I don't have a custom recovery nor when I do flash one it still doesn't work. I believe it may be a hardware fault at this point. Any help or advice would be appreciated. Cheers
Greetings everyone,
I decided to post my problem with my phone after searching the entire internet for similar problem but with no luck. Anyway I used to play around with my Samsung j7 pro for 2 years, I managed to flash twrp and thus many other custom roms, until last week when I recklessly flashed a sboot.img.tar file through Odin in order to fix cellular network in a rom I flashed earlier, this alone bricked my phone refusing to get past the Samsung logo, so like I do always, I tried to restore my phone by flashing the stock firmware (9.0) which I always keep on my PC, but surprise, the phone refuses to go through the process and gives me this error:
sw rev check fail bootloader device -1 binary 6
(same with 8.0 and 7.0 firmware)
I searched the internet for same error but with no luck, because I understand it's a mismatch between device bootloader current version and the firmware bootloader's, that they should be the same or higher, meaning you can't downgrade, I get that! but I never seen device with negative figure (-1) what that's supposed to mean? my device bootloader used to be on 6, how did it managed to jump to minus one ?
then I tried to flash TWRP to see if I could flash a rom and get around it, so I did, but when booting into recovery the screen goes black, I thought first the phone turned off, but not really, because TWRP seems to work with screen completely black, I knew that because I accidentally touch the screen and I sense vibration, I managed to reboot the phone via twrp just by guessing the buttons location (screen always black) in order to prove that TWRP is working with screen off. I tried to flash multiple TWRP versions but the same problem, no screen just touch, by the way there is nothing wrong with display hardware because it shows Samsung logo at start and also can boot into download mode just fine.
I hope someone could help me overcome this big of an issue, because I tried everything.
