T-Mobile LGV20 H91810j KDZ - LG V20 Guides, News, & Discussion

have at it folks... grabbed from LG Bridge and updated from it as well... https://drive.google.com/open?id=0B6Wj13Rw1kw-QTViRFJRaVRHQnM

Was just about to post this haha so here is a mirror if anyone needs it.

Can I upgrade from rooted 10d with this? Or do I have to update to 10i first, then 10j? Also what settings to choose in LG bridge?

If your using the image posted you can use LGUP, if your using LG Bridge it will download the image for you.
You need to be on a stock ROM I believe, I flashed the stock odexed rom. You can try it on a custom ROM though and see what happens.
If you want to use LGUP then you can download the above images.

What about stock recovery? Is that needed? If so how do I flash that?

It just overwrote trwp when I updated.

my upgrade steps were as follows:
backup anything you might need from the internal memory - /sdcard
backup anything you might need with TiBackup (just in case)
boot into TWRP and make a backup of /data
update to 10j via LG Bridge or LGUP (you will be returned to stock after this)
boot up and follow @jcadduono's post on rooting H91810d with recowvery
his detailed guide will leave you in TWRP with a freshly formatted and unencrypted /data
restore backup of /data in TWRP
done. profit.
NOTE: crucial you backup your /data in TWRP prior to updating because after updating your /data partition will be encrypted and you will no longer have root. once your /data partition is encrypted TWRP won't be able to see it. I believe you can still root with an encrypted /data where you'll then be able to use TiBackup to backup your data, but this method would be a slow restore versus restoring via TWRP.

Here's another mirror for those interested. All three files are in a ZIP since Android File Host doesn't play well with uploading KDZ files.

Can anyone extract the ing files and make them flashable so we can update through twrp? My hard drive went out last week so I can't update and keep root without doing it through twrp.

You just need to build the file tree and make a script to tell them where to go, I believe.
Or we could at the least flash a 10j based rom and then install the system img over it. Just need the extracted imgs from the kdz that way.

Um so after updating no more TWRP and still can root bit confused here?

updating and rebooting will revert you back to stock... you'll need to redo the steps for recowvery to install TWRP and root again... you'll also need to backup your device as you'll need to wipe /data to unencrypt

Can I just take the OTA to 10j and wont cause any bootloops? then just re-root?

Is this 10j rootable as 10i? Someone did it?

Has anyone got H91810j rooted? Yes? Link me to a source with walkthrough.
SW: H91810j
build: NRD90M
Kernel; 3.18.31
amdroid securitu patch 12.1.16
security software version MDF v.20 rls 4

Yes its possible to root the 10J patch. You need to do the commands manually.

I've ran the commands manually and I get confused about the .xml copy being put into local_manifests. I made the directory in my C: drive but Its a windows not linux computer I have access to. Does that matter?
So I get to the manual inputting part, right... And prompt says can not find file
at the first manual input of dirty cows command prompt

Just wanted to thank you, because you're a lifesaver. I bricked my phone (unfixable TWRP loop), and I tried downloading the KDZ several times from LG-firmwares, but it was extremely slow and always ended up failing. Then I found your Drive link, and approximately 9 hours after bricking the damn thing, I was finally able to fix it. Learned my lesson, too. I'll never again mess around with a new phone BEFORE acquiring any and all recovery tools, especially from a new manufacturer (I'm used to HTC).

Hi guys, in need of your help. I was originally on H91810D rooted and decided to try and install the OTA update not knowing that I would get stuck in a TWRP loop. I've downloaded H91810j KDZ file along with both LGUP and LG Bridge to try and flash the KDZ onto my phone, but neither UP or Bridge detects my phone connected to the PC, but Windows 10 detects that my phone is connected. I'm stuck sitting in TWRP and no matter what I try, it won't work. Any suggestions on what I can do to get through this? Any help is appreciated. Thank you!

Thank you.
I rooted to gain access to ad block for apps but now with Lollipop the app does not work. So I was thinking of going back to stock. Thanks for your hard work.
Anyone know of a good app that blocks ads?

If I used the one click root method to root my device, can I do re root doing that method again and regain twrp?
Can anyone report how the 10j update is running if it has changed anything for the better or sped up the device I know its for the stagefright patch but there is supposed to be other fixes in it also to speed up things ????

YES, if you flash this Restore Rom or any other rom just follow the right instructions about Root like if you are in 5.1.1 use the LG_LP5.1.1 One Click Root Method in This Thread (Click Here) and follow the instruction for TWRP

about speed i haven't had a performance issue at all since the first 5.1.1 update, so my device still/been snappy since then.
Okay so i updated my phone to the 10j upgrade and also re rooted. Do i need to keep the bootstack zip and the return to stock zip? or can i just delete those zip files?

No need to keep them just do a backup using TWRP to be safe in near tweaks or updates or any mess
I don't have a computer to update to 10j can I use that bootstack.zip with the debloated Rom? Basically can I use that bootstack.zip by itself to update the radio/modem/stagefright?

I tried gametheory's 10j it softbricked my device. I had to use the original LP5.1.1 to get it back. Will flashing your bootstack and v4 debloated together work? I don't have a computer to kdz my way out of it. Will flashing your bootstack put recovery back to stock?
My stock ROM backup is the original 5.0.1 firmware and updated with the LP5.1.1, anything 10j softbricks device and I need to flash the LP update to get it back.

Yes flashing Bootstack+Debloated_v4 work together ,(both are for v10j update)
What you mean anything v10j softbrick?
GT updated the v10j zip a few days ago adding the bootstack+preroot and Is that including my Stock Restore? If you go Stock Restore make sure to have the TWRP img file to flash while still in recovery cuz as soon you leave the recovery without flashing TWRP again youll loose TWRP and need PC to get back...
PS. Wipe Cache+Dalvik after flashing everything.

No, your bootloader will not be locked. There's a setting in developer options called "Enable OEM Unlock" which unlocks the bootloader. There's nothing I wrote in that post that suggests your bootloader will be locked. You will also keep root and twrp if you flash my v10J from that post.

You can flash this TWRP after going back to stock..
twrp-2.8.7.0-10j.img
Found here..
https://www.androidfilehost.com/?w=files&flid=33154
TWRP Will flash an image. Just make sure you don't reboot after flashing stock stuff stay in the recovery you won't get back into TWRP if you reboot right away. Also find the supersu zip so you can root.
total noob here
can anyone give me a step by step on how to install stock firmware on the lg ms631 without using twrp? I see threads that say use LG Flash Tool, but it says to select 'CDMA' and this is a GSM phone, so I want to make sure I won't damage it. Thanks for any help you could give me.
Follow those directions, there's nothing wrong with them.
i tried this and ended up in an lg logo bootloop....tried to go into recovery on lg h631 and my only option is a factory reset on this phone... recovery wont even come up..tried that and only get a black screen....it turns off apparently....any help?

LG G5 H830 10a will not update

So I'm having an issue with updating my phone.
I have tried reading all of the threads, but so many things are still a mystery and are confusing. I haven't been able to get a full understanding of all of this.
I have a LG G5 H830 10a T-Mobile variant.
I am running Android 6.0.1
I have a custom recovery of TWRP
My phone is rooted with SuperSU also.
All I want to do, is to update my phone to Nougat. What is the process I have to go through? After reading all about it, here is my assumption:
I download Flashfire and use DisableService to disable my root and SuperSu, then I run the OTA Nougat update...
That didn't work. I got an error from TWRP that said:
"unable to flash update.zip from cache/update.zip, update is meant for "h1" device, your device is an H830"
Or something along those lines.
I have a Nandroid backup, so I'm not worried if I brick or soft brick it.
Any help please?
Thanks!

You're not going to be able to update to Android N yet if you want to keep twrp and root. Only way to do it currently is if you have 100% stock phone and update via ota or using the zip file that was posted. If you don't care about root or twrp, update to 10j using the complete zip that autoprime posted and don't install SuperSU or dm-verity and let boot. You will have 100% stock and can take ota or use zip method. *** There is no current way to get root or twrp for t mobile version once on official android N yet *** So if root and twrp are important just wait until autoprime gets a chance to upload the flashable zip files for N to flash in twrp. You could also use cm or cm based Roms if you want android N, plus those are 7.1 stock is only 7.0, but if you want stock rooted just have to wait until it's released.

Ohh okay, perfect thank you!
With that in mind, I had another question..
I have an LG V20 as well.
One thing I was thinking of doing was the following:
Unlocking the bootloader, putting a custom recovery like TWRP on it.
Make a Nandroid backup.
Then root it, and then go about my business. If something like this happens again and I want to update, I can simply do a Titanium Backup go to my Nandroid backup, restore it. Then update OTA, then reroot, run titanium backup restore, and then I'll be back where I left off.
will that work?
And one last question:
How would I go back to factory settings on my LG G5?

I'm not 100% sure but I don't think that would work as once you install twrp it modifies the recovery. IMG which would cause ota to fail. But on the other hand, you could most likely do the same method as the g5 to go back to official and take ota. Flashing the complete zip (if those are being created for the v20, haven't checked that thread as I don't own that device) and not re-installing the dm-verity or SuperSU will always reinstall the original boot.img and recovery.img and be 100% official stock. Hope this helps.

Problem after flashing firmware and skipping Supersu

So recently I wanted to flash 20a via twrp on my G5 but it wasn't working. I reflashed 10i and my phone didn't want to boot up. So I decided to charge my phone after reflashing 10i once again without flashing supersu and I powered off the device and it turned back on with the "Your device is corrupt and it cannot be trusted sign" and so I tried to boot to recovery and my phone just factory reseted itself. I tried to boot into recovery with adb but to no avail. I even tried to flash 10d kdz and 10d tot both getting an error on LGUP and my phone is still stuck on firmware 10i. I even get an error when trying to update it with stock recovery. So now I have a phone with an unlocked boot loader and I cannot reroot again. Is there a way I can regain root? I knew I should have flashed supersu

I bet you didn't followed or read the 20a thread by autoprime nor did you bothered to read the TWRP thread as well. there's still a bug that prohibits you to downgrade from 20a unless you have a nandroid backup or a twrp recovery backup for the 10i. best option for now is to go back to 20a and wait for an update from the devs on fixing TWRP or try to follow the dirtycow method.

Look under the dev thread on autoprime topic about the stock N zips, if you read through last few pages you'll find all the links you need for recowvery to get root and twrp. Also if you're on 10i, why not just use lg up (make sure you either use older version or autoprime uppercut app) to flash 10D tot that already has twrp and then upgrade to stock 7 through twrp. Either way, all the info you need should be in last 3 pages of that thread by autoprime.
*** Edit ***
Just reread your post. If your getting errors flashing the 10D tot it's most likely due to you updating lg up, the .DLL, etc to install N. If so, uninstall lg up, and then download the lg up files and. DLL from the 10D thread. You can try uppercut app too as it's supposed to work between versions but I have not tested it myself. If all else fails then use the recowvery method.

Yeah not sure about uppercut. If you're still on 10i you should be fine using lgup to downgrade as long as you use the right version of lgup and h830 .DLL file. Also I'm not sure you can use refurbish option with kdz, but I know you can with tot. So maybe downgrade to 10D using tot and upgrade through twrp. If all else fails, use the recowvery steps on the above linked thread and you should be all good. Quick question, when you first start your phone, does it just show phone can not be checked for corruption or does it show the message can't be checked for corruption and visit this site... Etc. ? Reason I ask is the second message is updated bootloader and you won't be able to use lg up to flash MM firmware until you downgrade your bootloader.

Updated bootloader? I had no idea that was a problem. But since I'm on 20a i get the corruption message plus the link so O guess my bootloader is upgraded. How exactly DO you downgrade the bootloader?
I will mention that I'm stuck without twrp

Okay since you have an upgraded bootloader and no twrp you will have to follow the steps in that post for recowvery which will give you Root and twrp. Once you have twrp, download the bootloader zip for whichever version you're planning on downgrading to (I.e. 10I bootloader if flashing 10i kdz) from autoprime and flash in twrp. You can also flash the complete zip (i.e. 10I complete zip) in twrp after flashing the 10I bootloader if you want to keep root and twrp (you will also have to flash SuperSU after flashing those files). But you can also flash kdz or tot with lg up after downgrading bootloader via twrp but you will lose root and twrp unless you flash 10D rooted tot.

The thread is:
http://forum.xda-developers.com/tmobile-lg-g5/development/stock-h830-20a-rom-flashable-zips-imgs-t3511294
If you're just trying to get twrp and root to downgrade look at the last 5 or so pages and look for the recowvery post. Once you do that visit:
http://forum.xda-developers.com/tmobile-lg-g5/development/stock-h830-10j-rom-flashable-zips-imgs-t3491363
and download the bootloader zip and then boot into twrp and flash the bootloader zip. Then you can use lg up to flash kdz file or tot file. If you want to do everything from twrp and skip lg up step just download the complete zip from the 10J thread and flash in twrp after flashing bootloader, then if you want to keep twrp and root make sure after flashing bootloader and complete zip in twrp flash SuperSU before rebooting.

I don't think so but not 100% sure. If you follow the steps carefully you'll be fine. I didn't directly post the recowvery steps as I have not used this (I've had twrp and root since 10D). You can look on the v20 thread as it has a post for the v20 and our h830 recowvery method. Sorry I can't be more help with that specifically.

How to flash via TWRP a stock ROM in my problematic phone

Hi everyone.
I am facing a LOT of troubles with my phone (as stated in this thread).
Anyway now I have again unlocked bootloader, installed TWRP 3.1.1, rooted but I have a strange ROM installed by a service tech shop after the phone became unusable.
The problem is that this ROM does not show an update option in settings so I am stuck at 1st march security patches.
Here attached my actual Build Prop file.
The ROM seems to be a BLN-L21C900B300 (never heard of this and not even found on Firmware Finder) and the fingerprints show a "test keys" rom:
device: HWBLN-H
Display: BLN-L21C900B300
Fingerprint: Huawei/generic_a15/generic_a15:7.0/NRD90M/jslave04010520/:user/test keys​
If I try to flash via TWRP a BLN-L21C432B360 (which was my previous stock ROM) it does not work and on TWRP appears the following:
......
write radio image
check_write_data_to_partition
write data error
E; unknown command (errno)
update_huawei_pkg_from_ota_zip: update package from zip failed
updater process ended with ERROR: 7
error installing zip file '/external_sd/update_full_BLN-L21_hw_eu_zip'​
I cannot flash the FULL zip file with the core of the ROM but I can luckily flash the data, so I could get back Radio Fm and possibility to install themes....
To make the story short: is there someone who knows what this error is? Maybe I can get a solution.
Moreover: maybe this strange "device: HWBLN-H Display: BLN-L21C900B300 Fingerprint: Huawei/generic_a15/generic_a15:7.0/NRD90M/jslave04010520/:user/test keys" is preventing me to flash?
Changing build prop file can be useful?
Thanks to all.

I forgot to mention: dload not working. Always error.
That's why I think TWRP is the only solution
B300 (at least for the BLN-L24) is the first of two update packages to rollback from Nougat to MM. The first update will take you from the latest firmware to B300 and then the second update will complete the rollback to your device's stock firmware.
dload this package to complete the rollback then do a factory reset and wipe cache partition in stock recovery. After that download and update to the latest firmware and proceed to unlock BL and flash twrp and you should be good to go.

but you mean that I have to downgrade from Nougat to MM again?
And before doing it I have to flash the stock recovery?
My phone was, we can say, flashed in some way by the tech shop to this strange version of Nougat and with the "test keys" fingertips.
With the files you provide I should "dload"?
I do not understand your post.
please explain better.
Thanks.

My phone was, we can say, flashed in some way by the tech shop to this strange version of Nougat and with the "test keys" fingertips. Like I said they did half of the rollback process which is why you are on B300 firmware that you cant find available for download

Download the zip I linked above from Huawei website. Extract the update.app and put it in dload folder on your external SD card and force flash (power vol - vol +). It will flash all the stock images and return your phone to factory firmware android 6.0 EMUI 4.1. It might bootloop after this but booting into stock recovery (power vol +) and perform factory reset followed by wipe cache partition will get you booting. Then you can OTA update to latest firmware and root again.
Well, I will try this weekend. Now the risk to stay without phone during working days is too high
Ah, BTW, thanks for suggestion.

Well, I changed my mind and tried anyway now. I was just too curious.
result:
Software install failed.
Incompatibility with current version.
please download the correct update package.​
As usual. Huawei sucks. Full stop.

I agree 100%
Since you have nothing to lose right now just try the whole rollback process. Here is the update that the service center used to get your phone to BLN-L21C900B300. You can try flashing that again through dload or skip to trying to flash this. There are two different firmwares listed as the 2nd part of the rollback and you already said the last one I gave you failed so give this one a shot. Let me know how it works out for you:good:

Have you tried the Team MT huawei multitool to flash the images from the firmware? Use the Huawei update extractor tool to get the boot,cust,recovery,system and userdata.img from the firmware you tried to flash and then put them in the unbrick folder in the multi tool. Put phone in fastboot and run the Multi tool and use the unbrick option. I know your phone is not bricked but this way it will flash all 5 images in order through fastboot. You could actually try and flash the most current firmware with this method and avoid having to system update from MM to Nougat.
yes, exactly, I am trying with multitool . another bro suggested me how to do it even if with a slightly different method.
"You need flash the oeminfo via multi tool and then same firmware file for your current version via dload. It should be fixed".
WTF....never sweat so much for a phone. And never had those problems flashing samsung... and I was flashaholic
Yes, I have learned so much about this phone and the flashing/brick/unbrick process in the last 2 weeks.

When I go to multitool "unbrick", it asks for custom.img, but in no update.app of my firmware is present.
Moreover now I just can enter erecovery. It does not boot. I can enter fastboot only. Multitool is now not recognizing the phone. Do you know how to proceed?
I put in dload the firmware .app, but it says "software install failed"
Pheew...I managed to have again that fuc..ng C900B300.
I entered fastboot and repeated the unlock bootloader process. That way the phone got a hard reset and started over. Believe me when I say I tried all the methods I knew.
I think there is something locked somewhere in my partitions (I am not an expert of course) that prevent me to do deep modifications. Now I just can TWRP data but not the core. And again I have no update option. I think I am stuck forever at this stage with 1st march patches and nougat 7.0.
I do not think I will be ever able to have Oreo.
Amen. I am really tired to waste my time with this s**t. Next phone will be again a Samsung or One+. Full stop. Stop chinese brands.
Where are you located, Europe?
Yes
Ok bro I really hope this is it. Full firmware BLN-L21C432B151. I already downloaded it myself and checked with extractor tool it has all the images you need. Since you have fastboot back use the multi tool unbrick again and now that you have all the necessary images cross your fingers it will work.
And I agree with you about the phone. Made up my mind im giving this turd to my sister and getting the OP5T in a few weeks.
Thanks. I will do it this weekend. Today I spent 5 hours to get back my configuration after the hard reset with the apps I use for work. Cannot risk again tomorrow.
In another thread, sashank suggested to change OEM file because probably phone doesn't recognize the firmware I want to install.
It didn't work and lead me to start from scratch with the same strange build.
I will try your method but first I must study better the procedure because I don't want to mess up everything and risking to throw the phone in the garbage (where it belongs in the end...).
Thanks.

Can't update

My device is rooted and i have installed a TWRP recovery, & i want to update it, but always stuck at the recovery mod with ERROR 7!! help plz
This is because you're trying to update without flashing back stock recovery.img of your firmware build, and TWRP isn't able to analyze and confirm the update package as valid before starting the update process.
To update correctly, extract the recovery.img (32MB like) from your update package (probably you'll need to downlaod the update.zip of your actual firmware if you didn't stored a copy) using Huawei Update Extractor program, flash it by ADB in the same way you flashed TWRP and once done, update again. Then you can flash TWRP again.
