t-mobile v20 h91810p twrp installation help! - LG V20 Questions & Answers

I know I need to rollback my version to 10k, however I am stymied by antirollback problems using lgup! I could really use some assistance on getting this to rollback to 10k. I have been reading the forums for 2 days now, hundreds of posts, and nothing works. I cant use the dirty cow method of installing twrp as it was patched and my phone auto downloaded the stupid update... Any help would be much appreciated.
Thanks Zernon916

You can't. You're stuck on P. You said it yourself it is anti roll back.

Right. Upon reboot after hitting start in LGUP, it went to the stock android firmware upgrade screen, said 100% and rebooted . Did a battery pull when the LG logo came up. Put it back in and used recovery button combo (Volume - and Power). Said yes 2 times and it booted to android instead of twrp.

Did you select the Partition DL option? Might need the common dll to be patched as well. I can send you the 2 files i replaced in the lgup directory

The root method does work. I'm not sure about the recovery part though.
**edit**
I went to this website and downloaded TWRP version 2.8.5.0 and it works. As for the functionality, i'm not sure. I tried doing the backup and it was working but then the screen shut off but the back and home buttons were still lit up and the screen would not turn back on with the power button so i just pulled the battery. Also of note, there are two strips of bright blue on either side of the main UI. There was an error that said the UI could not load properly, but like i said, it was starting to backup. I'm more of a CWM kind of person so i am going to try the T-Mobile version of that and see what happens. http://techerrata.com/file/twrp2/trltetmo/openrecovery-twrp-2.8.5.0-trltetmo.img.tar
Good luck.
**edit2**
I turned off the screen timeout feature and the backup went fine. I'm going to test to see if I can restore from that backup tonight.

Thanks, I'll give it a shot. Just to make sure I'm not misunderstanding, this recovery is what will grant me root, correct? It's my first time messing with CWM so I'm a bit worried.

Whoa wait. First you need to follow the root method by flashing the sc-01g recovery. Boot the phone and install/update busy box and SuperSU. Then you can reflash to twrp or cwm.

Very nice sir! It's about time this leaked! I'd hit thanks more than once if it would let me.
I've never needed it, but always been just a little cautious with this little tablet due to not being able to do a full firmware restore myself.
You should be getting a flood of praise from all the folks who took the lollipop OTA and lost the ability to root and run bumped boot images. :good:
I recommend using timmytim v410 stock rom after downgrading with the kdz because the kdz is simply a test kdz lol so just Google : V410 Stock Rom

You can check by going to settings then security and at the top it should say decrypt..(Or if it's not encrypted then it it will say encrypt) if it saids encrypt then i dont kno what else you can do maybe try reset your tablet or if it saids decrypt simply decrypt it and enter the pin if you forgot it you can probably try resetting your tablet i dont kno if that'll work or not but it should

Poll - Is root working for you? (T-Mobile Variant ONLY)

I want to take a poll, and this will be for T-Mobile variants ONLY. Being that the thread has people from all different carriers posting results, i think it's rather confusing to anyone reading along trying to decide whether or not to give it a shot.
So, have you successfully rooted/TWRP'd your TMOBILE variant LGv20?

You did not do a backup in twrp before flashing your file? You may have to exchange your phone you should always make a backup especially with things this new
Unlocked and rooted with no problems. I flashed a systemless hosts file for ad away in twrp and everything was fine. For assistant, I manually edited the build.prop file and restarted, which worked great. I almost feel guilty as to how easy this whole process has been.

I assume the build prop edit changes the device name. Therefore lg up won't recognize it. You will need a custom .dl file with the name edited. At least that is what used to happen back in the day when I was working with these phones. There used to be a program that made it possible to edit the .dl file.

Full stock ROM to flash

Hi,
I have Axon 7 A2017 China. I'm looking for a full stock ROM to flash using TWRP.
My Axon is not booting to Android but I can boot to TWRP. I was on 7.1 before it stopped booting. It stopped after I attempted to flash Open GApps which failed buy then the phone stopped booting.
I was looking a lot for the full ROM but can't find it.
Any other suggestions to get the phone working again are welcome.
Thanks,
Edit: im stupid. Sorry, was to late yesterday.

You can find the A2017 stock ROMs on 4PDA. Go to the 4th categ brick repair manual, click on the link that says 'Miflash and drivers', and open one of the spoilers (no need to translate, it's straightforward) (i think it's the 2nd spoiler). Then download one of the images such as A2017_Bxx_NOUGAT_FULL_EDL. But BE SURE that it's for your phone!
If you want google stuff on your phone look for Xiaomi's 'Google Installer'. it'll just download the apks and prompt you to install them, and you'll get google

Well you obviously can't flash it via TWRP since it's a MiFlash package lol - to flash stuff in MiFlash you don't use zips, you use folders. Take the zip you downloaded and unzip it somewhere on your PC. Download MiFlash and
You need to go to TWRP, then from your PC issue 'adb reboot edl'. the phone will look like it's off but it's not. Open MiFlash, select the folder you unzipped (if you open that folder and you find only one folder inside, select that one) and press Flash or Start or whatever the start button is

Successfull roll-back from oreo Beta back to Nouget

After using the manual Oreo update 2 weeks, Flashing several treble roms. Most with little to no trouble. I ended up with no more 4g or LTE signals on my L24 USA model Honor 7X.
So I took the plunge and tried to roll-back from beta oreo back to EMUI 5.
It worked. It took only few minutes to complete. I wrote down the steps, it was 22 steps.
If you do attempt this too, be advised I do not know what possible things could go wrong, and you do so at your own risk.
I will likely refine the document if after reading it many times I find it too confusing.
You will need backed up images of your original firmware. AND the original /data/hw_init folder
If / when huawei finally release a "full-ota" for your device/ region . this will not be needed, but until then here is a method to return.
Thanks are needed here:
pro-team-mt for firmware
@Askuccio_DROID no-check recovery
@Sudeep Duhoon twrp recovery , and backup instructions

Nice
I bet many users will follow this tutorial in the next days....
I was worried cause of the partition changes on Oreo that the downgrade would be very trick... But you got'it right
Still, wont work for me... (Stuck on FRP)
On About the Phone, is the model correct? Isn't it BND-AL10? (Since you used that model's image)
Great work.
Any tips for me:
- Boot phone
Using the SD card, is there any trick to prevent the phone to reboot? Any app? Any other trick?
- UPDATE.APP
All the files that i tried, NON make it passed the 5%...
This is the only way in that i have to the device...
-Relock Bootloader (?)
Just can't do it via Fastboot... Is there any other way?
Keep the good work

I have BND-L24.
I used AL-10 , basically at random. Firmware finder showed they had a roll-back fukk-ota.
My about phone screen shows correct . Even when I booted the China firmware.
Great work.

The file is already linked on the directions.
These directions do not tell you to use the hwota-auto-update.zip. if you are following those direction, kindly ask in that thread
Big thanks for the hint to use "adb reboot recovery" instead of TWRP's reboot button - I've been pondering for hours over what I've done wrong, and turns out this was it.

After using the manual Oreo update 2 weeks, Flashing several treble roms. Most with little to no trouble. I ended up with no more 4g or LTE signals on my L24 USA model Honor 7X.
So I took the plunge and tried to roll-back from beta oreo back to EMUI 5.
It worked. It took only few minutes to complete. I wrote down the steps, it was 22 steps.

No, it is based on using a modified stock-ish recovery, which needs unlocked bootloader to flash.
And besides, this was a hackish method to get me by before there was a full OTA file for roll back.
I think your best bet on locked bootloader will be the host file mod and python server method hackintosh has talked about. He calls it erecovery. And it is intended to be done with the stock erecovery.

Hey I've posted a few posts around on one of these I got the SE on the latest firmware. I'd there a way to downgrade to earlier Oreo or nougat service rom without bootloader unlock. I bought the credits then found I was to high of firm Ware. I can't find straight answers any where I've spent all day downloading, and trying to update, flash whatever I can all ending in error. All bnd l34 I've got 344 it's files which fail at 5% I've never used one of the fancy heuweis before. Used to lg and Samsung. I'm no noob on flashing . Hisuite does not show rollback options... Like I said just can't find any straight answers. I'm stuck with this one either way but root would be nice
