Rooted T-Mobile H932, Flashed Custom Rom and lost fingerprint reader - LG V30 Questions & Answers

So as the title states, I rooted my H932 phone today and flashed Havoc. During the initial setup it asks to setup my fingerprint reader which worked correctly prior to root and it seems not to recognize my fingerprint. Clicking the button triggers the power options and all of that is working fine. Do I need to flash something else that I a missing?
Thanks

Did you ever flash latest stock firmware? Or did you root on 10D and rush to a custom ROM?

Edit, you should post in Havoc for support.

I was on the latest stock firmware. I followed the instructions to downgrade to 10D and then I rooted the device. Once rooted I wiped the data folder and installed COSP which is when I noticed the fingerprint sensor not recognizing my fingerprint during setup. I switch to Havoc to see if it was the COSP rom but I got the same thing during Havoc's setup.

Yes, after being rooted in 10D, you need to flash latest stock..

Really better off asking in the custom ROM thread. I think most of us are on LG stock ROM since it's better.

OK I'll flash back to the latest stock ROM and then try another custom ROM. The whole reason I rooted was to get away from LG's rom... hate the bloat/skin.

There are many changes since 10D, that's why you need to first be on latest firmware then wipe and install a custom ROM.
Also I've seen MANY post about fingerprint sensor not working on custom ROM's. It's always due to a user being on 10D and going straight to a custom ROM.

Read the Root Sticky. Post #2 is specifically about custom ROMs.

Flashing the latest stock ROM and then AOSP based rom fixed the fingerprint issue. Thanks everyone

I want to flash to CM13 but I am at Lollipop and rooted with TWRP

I saw a same thread but i am using KII-L22
what should i do first? i think i had a backup where i am still unrooted but already have TWRP.
my guess is that I should reflash to stock recovery first then update via OTA to marsh mallow then root and install TWRP again then flash CM13.
if my guess is correct then how do I revert from TWRP to stock recovery?

Grab the stock recovery of KII-L22 and flash it using fastboot. Same way you flashed TWRP.

Do you have a firmware online on Huawei website or in 5X file repository.
If yes, just use huawei update extractor to extract stock recovery.img from it.
That's it! Search for any KII-L22 stock firmware then extract the stock recovery from it.

will it work even if the stock rom is from MM not Lollipop? can't seem to find the Lollipop version.
if its compatible then this will make it easier since ill use the full stock rom after flashing the recovery

I suppose it will still work. Recoveries are seldom tweaked.

It's better to be safe than sorry
Just google huawei firmware finder by team MT, install and I am sure you can use it to search a lollipop firmware for your phone.
If you want to install MM directly then get MM firmware, extract recovery, flash it and use three button method to update.
You will lose all your data in this way.
i found what you were referring to sir adrian. i will give it a shot and give feedback. thanks everyone.

Yes. I am in B310 when I flashed CM13. B350 is fine. B360 is the one with bootloops.

I have a similar problem here: I have an unlocked and rooted KIW-L21C432 with Resurrection Remix installed and a backup (B140 firmware version) where I already have TWRP installed as the recovery but am not rooted yet. I want to go back to stock in order to be able ro get the OTA for MM and then install the most recent Resurrection Remix ROM.
adriansticoid said:

So, what would be the procedure for me?
Flash the (unrooted) B140 backup using TWRP.
Use fastboot to flash the correct stock recovery from the honor 5X file depot issueing:
Code:
fastboot flash recovery recovery.img
.
Upgrade to the most recent firmware version B340 via OTA update.
Flash most recent TWRP version using fastboot:
Code:
fastboot flash recovery twrp_kiwi.img
.
Root and flash CustomROM.
Is this correct? Is there any smarter way to achieve the official update to MM (like those full revert packages I read about)?
What if my backup was rooted already? Would this lead to any problems? I am not 100% sure whether I was maybe already rooted when I did the initial backup :/
Thanks and best regards

Yes that's correct. You need a clean, unrooted stock so you can update officially

Thanks, but what if the backup is rooted as well? Do I then have to do the manual MM update procedure described here?

How exaxtly can I tell? It was rooted when I was still on 5.1.1 (firmware version B140), so I'm not sure whether it's systemless root or not.
Then flash full B330:
http://download-c.huawei.com/download/downloadCenter?downloadId=90763&version=354362&siteCode=fr-h
Put the (uncompressed) DLOAD folder at the root of your SD Card.
Power up the phone with Vol up & vol down pressed, then release once you show the logo, it will automatically flash the rom.
Once done, you are on stock unrooted B330, then you can boot/flash TWRP, then finally flash CM13.

Constant restarts on Pie custom roms

Hello.
I am facing constant restarts on any Pie custom rom. I use reccomended treble TWRP, i have newest MIUI firmware, i wiped cashe\dalvik\system\data, and i formated data completely prior to installing. As soon as it boots, it restarts, and it happens over and over again. Am i missing something?

No. I had similar experiences. I eventually got GZOSP, which proved stable. I'm back to Oreo, of course.

I managed to figure it out. We need MIUI firmware based on global 8.1 rom (i had latest weekly build, but based on 7.1 rom). Just flash this and you are ready for Pie. Installed AospExtended and everything works great so far.

Advice on getting back to stock LG H930(Europe)

Hello guys,
I am currently on LOS and planning to go back to stock ROM.
LOS was flashed over the downgraded firmware necessary to unlock the bootloader.
Would it be advisable to flash the latest stock over it or should I rather go back to the downgraded ROM and upgrade it through OTAs? Are there any partitions flashed through OTA that would be otherwise missed by TWRP?
Also, can anyone recommend a debloated, optimized Android 8 ROM for this phone?
Thank you for your time!

There are TWRP flashable zips you can use.
See the H930 KDZ thread for instructions on how to flash them.
https://forum.xda-developers.com/lg-v30/development/h930-lg-v30-european-market-h930-t3779076
Be sure to use the stable TWRP linked in the WTF thread, not the new beta experimental TWRP listed elsewhere.

Quick question please, are the ROMs in your thread upgradable through ota should LG release one?
I noticed you mentioned after each build that they're not meant to be upgraded.
I may have a case of the stupids here but does it mean that once you flash one of them you're stuck on that version?
PS thanks a lot for taking the time to answer these questions. I appreciate your help a lot ^^

¿TWRP Flashable Stock Firmware?

Hi there
Is there any way to flash the stock rom from TWRP?
I read about the Lazy flasher zip for MIUI roms, but this device has Android one. I don't know if there's a way to go back to stock flashing the firmware from TWRP. Help ?

The stock firmware is the first list. Pick recovery ROM
I picked the TWRP option. Now i'm back on stock. I've lost TWRP, but fingerprint scanner is back, thanks a lot!

If you flash any ROM in twrp it will erase twrp (except syberiaOS which comes with a prebuilt twrp)
