Advice on getting back to stock LG H930(Europe) - LG V30 Questions & Answers

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 ^^

Rooted with zedomax how to ota?

I am stock, locked, s-on, and rooted with zedomax one click so i could use wifi teather and titanium backup. How can I apply the ota and still keep root? If that's not possible what do you recommend?
Are u using a custom Rom? If you are then wait for one of the Rom developers to incorporate the latest ota.

Noob here don't know how. I thought I couldn't flash any Roms with zedomax one click root method and locked s on. Detailed instructions would be greatly appreciated.
Can someone be straight up with me and tell me why no one has answered my question?
no one will give you a straight answer because what you want to do is kinda not recommended on any device.
general rule of thumb is not to ota after root. so what you should do is get s-off using lazypanda which allows for flashing of custom roms and such and follow my guide that is in my signature to make sure that it goes smoothly (but ignore the part of flashing fresh rom, you can do it on stock with just root) then once you achieve s-off you can either stay stock and wait for a rooted version of the newest update for you to flash through twrp or you can flash any other rom (i run flex 360's rom, i find it the smoothest rom ive tried) and then just flash the radios from the newest update which will give you all of the 3g improvements (which is basically all you need, you can flash roms based off of the newest update at a later time)
if you need any further help feel free to pm me at any time and i will help you out
edit: also, after re-reading your original post, there is no way to keep root after ota so if you accept it you will have to wait for another root exploit which may take a while.
Can you give us new guys a step by step instructions for installing the new ota update> I have stock rom phone rooted with TWRP. Do we need to do a factory reset and clear the Cache, Dalvic Cache and System or can we just install the Odexed zip?
He can't flash a Rom guys, he can't get a custom recovery.
Op, get s-off first and the. Get your recovery and flash a romt

Update to MM after using rooted, debloated stock ROM

I just got the MM update warning on my V10. Currently using Stock, debloated, rooted ROM. I'm thinking I want to upgrade to stock MM 6.0. I tried the install but it rebooted into the customs recovery. How can I get the MM upgrade to work from the custom ROM I am on?

First you'll need a new recovery TWRP 3.0.2
Second - You'll need to delete the ota update because once you "accidentally" install it you'll cry that you cant root and want to downgrade back to LP.
C. Go to the Dev section and Download the Rom that was built using the ota i just told you to delete. You'll be much happier with a Rom rather than a OTA update thats non-rootable.
Oh..theres also multiple threads regarding the ota.. Doing a simple search wouldve made things a lot easier.
Heres the link to the MM T-Mobile H901 V20E Rom.

Well the OP of the link I posted updated his 1st post. But since you're rooted you should just be able to follow the instructions.
1. Update your recovery to TWRP 3.0.2 (GROGG's build)
2. Download the Rom. Its a 2 part Download. So you'll need Part 1 and Part2 build 005
Dont flash anything until youre certain your recovery is 3.0.2 otherwise you might end up bricking or certain partitions might not be flashed.
If anything read the link OP a few times.

To flash the latest version of CM, be sureto have updated your phone officially to Stock Marshmallow. If not latest CM will not flash. You an error.
I'm guessing your phone is Indian version? Anyways go to the huawei website of your country. Download the marshmallow software file there and upgrade it through force update like i recommended here -> http://forum.xda-developers.com/honor-5x/help/gr5-help-t3443573
I think you should go into your current custom recovery first and wipe data/factory reset. So u don't get bootloop as a result of CM files being on board currently.
The firmware in the link above is not for your country/device but for Egypt KII-L21CUST185.
So get the correct file for your device for your country's huawei website as mentioned above.
After flashing successfully, you have to flash custom recovery, again. Remember the whole 'fastboot flash recovery recovery.img' process then flash SuperSU in custom recovery to root? Yeah do that.
Now you can flash latest CM build again. Cheers!
Note: If your country doesn't have marshmallow (6.0.1) available, don't bother with the process as latest CM build will not flash.

Hey guys, it's been awhile again, and I've yet to flash as accordingly taught. So is there already any easier method than flashing stock MM based EMUI and flashing again to custom?

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

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.

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

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.

Flashing Custom ROM on Mido

hello, i'm new mido user, i'm using ido too. i wanna try flash custom rom on mido, is it necessary to flash firmware before flash custom ROM, and what's the purpose we flash firmware? bcause in ido, we don't need to flash firmware before flash custom ROM. I'm still looking for the answer of my question, i hope someone can help me to explain it, thanks
Hmm, what do you mean by firmware?
The steps are:
1. Unlock boot loader
2. Install custom recovery (TWRP)
3. Install custom ROM

Oh that. That's only required to flash firmware when you're coming from marshmallow based MIUI only. Otherwise no need.
The thing is if you flash firmware before installing Rom, it's not an issue. You're good to go. You can find latest firmware zips from this (https://forum.xda-developers.com/re.../firmware-firmware-update-2017-08-04-t3651537) thread, huge thanks to @Zile995 for the updates!
