Hi,

What recovery are you using? Are you sure you have a good download? There's no assert in the zip at all so if you're getting that message, then something else is going on with your device. Can you post the recovery log?

TWP

I put a screen from twrp:
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] The_Walking_Playground:
Hi,

First of all, that's not a recovery log. Second, you're not flashing the vbmeta zip (which is your actual problem).

TWP

P.S. It may be easier if you don't rename the file. It'll flash fine that way.

ViperExperience Alpha 6 Update

​

ViperExperience Alpha 6 (19 August 2020)

Fixes& Updates

Fixed HTC's wired headset issue

P.S. At this moment I'm not able to work on ROM fully. Unfortunately, my U12+ doesn't turn on anymore and I have to wait and send all my builds to testers that not so much effective like when you do it by yourself. I hope all problem will be solved soon and I will be able to work on the rom fully. A lot of things like FaceUnlock, all Camera features and OTA Updates require deep learning of all mechanisms in original HTC U12+ ROM and it take a lot of time. So please be patient and sorry me if smth doesn't work properly. I'm trying to do all my best that I can.

Thank you for the update! No issues to report other than I still cannot get applications to recognize high accuracy location. Is anyone experiecning this issue? Each location option is turned on, but there is not a "high accuracy" option. I do have the Google Location Accuracy enabled, but apps do not recognize this. Any workaround? I have also tried installing Global Optimized GPS File Replacer within MAGISK, but nothing seems to work. Thank you all in advance for any assitance.
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] Sephiroth43:
I can confirm this issue partly. Sometimes it is working after 5-10 minutes but often it doesn't find my location on gmaps or here maps. Everything turned on and permission for location set to always granted. I hope this can be fixed easily. Except GPS everything working, for an alpha build very good work.
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] WPtE:
Honestly, as HTC users we've learned to be patient for updates :silly:

Looking forward to trying this out on my phone, once it's in a more stable state, I need my phone to often to run an "unstable" alpha.

Thanks for your dedication :D

i used the stock rom, installed magisk last night and from a minute to a minute it startet.

flickers in recovery also, but not in download mode. stock rom per ruu file doesnt helped
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] Langley Ding:
ROM works perfectly except a completely broken brightness config. Whatever the brightness level or automatic brightness was set, it keeps on the max brightness level. The brightness stuff is used to working well on both EU and Asia RUUs.

The device is imedugl engineering version(don't know how to describe this in English correctly, sorry)

You're experiencing flash trouble even though you did update your adb.exe and fastboot.exe in toolbox? I'm using "HTC10 Batch Tool" that should be more obsolete tool than you, but updating internal exe files can make flash and boot in normal to me...

Hey Guys,

awesome Rom, thank you very much!

After trying some things to get everything running and flashing the rom for the fifth time, I'm stucked in the Bootloader. When I try to get into Download Mode I get redirected instantly into Bootloader. I have never had something like that before, but I don't have any change to get my U12+ running again. I tried everything I found. Even flashing the RUU with SD-Card-Method is not possible without Download Mode. When trying to boot twrp from bootloader I get this message: "Not allowed on PRODUCTION device". But this worked well many times before.

I will be very thankful for your ideas.

I have installed the Alpha 7 update yesterday evening and first off all: Thank you very very much!!

A few things I noticed the first ours on Android 11 (sorry for my English):

- update was very fast, first start-up was a minute (no update of apps as the Alpha 2-6 updates) so I had doubts the update was done but it says Android 11, had to re-personalize my home screens

- it says security update 1 December 2025 :)

- battery life seems to be improved a lot (lost 14% stand-by over night, was 30% on the Alpha 1-6)

- camera app much faster (in fact the whole phone seems faster/smoother)

- start-up phone much faster

- google maps not working anymore (last update from Google didn't make the app better anyway, now installed Maps Go)

- Bluetooth speaker and headphones working without the need to re-connect (car not tested yet), wired headphone still not working

- No more pop-ups saying Updater stopped

- No dark theme on the Call app (not searched in the settings of the app itself yet, brightness screen still can't go under 59%)

- All my installed apps just work smooth and fast

Very happy with this update so thank you again!
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] maharadja:
I don't understand why you can use your bluetooth i can't activate it...

The porblem, google maps FC i recognizing to.
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] mikalovtch:
To fix Bluetooth you may need to remove BluetoothResOverlay.apk in /vendor/overlay/ . Do not forget to make vendor partition backup in twrp before doing this action.

The latest version of Google Maps doesn't work but 10.54.1 works fine
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] mikalovtch:
Security Patch value is taken from vendor partition to pass safety net. You can be sure, the ROM was compiled with the latest available Android sources.
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] mikalovtch:
You have to flash noverity vbmeta to boot this ROM

Okay guys, If anyone knows if what I did here is repairable, then great, if not then... This would be my first bricked phone and I have been on here since the palm treo 700w and have never bricked a phone to date. If this has to be my first, then I feel pretty good about myself over all, but this is a bad time to buy a phone with everything going on.

Anyway, I had trouble using fastboot to flash system (said insufficient space), so I oem rebootRUU and tried to repeat the flash. It succeeded, and I was able to reboot back into the bootloader. I tried to boot TWRP and the screen went black with nothing working and only the power button vibrating slightly upon press. Any thoughts on what happened and if it is repairable? (I bought a new battery and decided pull it apart in order to replace it, I decided to cycle power from the battery connector, but now it does nothing. ) Any thoughts?

I did the same thing, after flashing Alpha 6 a few times, I decided to go back to stock for this day. I wanted to have more time for the setup of alpha 6. Now I have my first brick I'm not able to solve by myself. Believe me I looked up every source I know. The Situations is the following:

- Stocked in Bootloader

- When I press "Reboot to Download" I got redirected into Bootloader instantly

- At the bottom it says "This device is corrupt. It can't be trusted and will not boot"

- booting a twrp image is not possible --> "Not allowed on PRODUCTION device"

Would be very thankful for help.

[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] Maverick_TN:
Mine said that as well, until I tried booting TWRP. At that point, the screen went blank and it wouldn't respond to fastboot or adb. Power button would vibrate, that's it. The battery is weak and I left it overnight with it connected to my laptop with the screen that you showed before then I tried booting TWRP and the screen went black and the charging light won't come on when connected to power. I cycled power connection by unplugging battery and now it's just inert...

Seems like you can flash a RUU at it's current state.
[HTC U12+ ROMs, Kernels, Recoveries, & Other Develo] Jonas22:
Hey,

unfortunately I can't flash a RUU. Everytime I try, I get the message 'Not allowed on PRODUCTION device'. I don't know what to do....

In your case, I was asking myself, when you connect your device to your computer, does fastboot find devices? (command: fastboot devices)

I hope we both will find a solution, never have been this helpless before:silly:

Hey,

thank you for your answer. I tried this, this helped me many times before, the thing is, I'm not able to get into the download mode. Everytime I pick "Reboot to Download" with vol + and power, I'm back in fastboot mode again. The download mode worked before, I used it several times. Now I'm not able to use it. Does someone know where it is located and is it possible to repair/flash it?

I just used this old method and it's working: https://xdaforums.com/showpost.php?p=81956001&postcount=3. It's may have side effect! Description it's also a bit out date so fallow on screen instruction. For me Google Maps not work but I didn't check before.

Don't do that because after some time system become unstable. I just use stock boot image.

Previously I had problem with no detecting sim card and fingerprint scanner. I don't have that problem ViperExperience Alpha 7 on stock boot image. Problem return if I install UPDATE-BeyondStock™-Kernel-Pie-v0.02-U12+_Exodus-signed.zip. [MENTION=3184278]mikalovtch[/MENTION] do you recommend specific boot img or whole firmware before use ViperExperience Alpha 7?
