Issues installing TWRP on LG V30 - LG V30 Questions & Answers

I've been struggling to get TWRP on my V30 (H932) from T-Mobile. I have already unlocked Bootloader and have activated USB debugging. I open File Explorer on my PC and go to my ADB folder where i have placed the TWRP.img file. On the search bar i type CMD in order to open a command window. Then i type "adb reboot bootloader" and my phone goes into fastboot mode. I have tried typing "fastboot flash recovery" and also "fastboot flash recovery_ramdisk" followed by the name of the TWRP file. Unfortunately, this is where i've been getting stuck. i get the following message:
C:\adb>fastboot flash recovery_ramdisk TWRP-3.2.3-7.img
target reported max download size of 536870912 bytes
sending 'recovery_ramdisk' (30860 KB)...
FAILED (remote: unknown command)
finished. total time: 0.013s
I'm not sure what i'm doing wrong in these steps. I have also tried renaming the TWRP file to "TWRP.img" but i get the same message. I read somewhere that using the OEM cable that came with the phone sometimes helps. I no longer have that cable so i can't try that. I would very much appreciate any suggestions to this problem. Thank You!

You're trying to reinvent the wheel.
The U.S. T-Mobile H932 was the last V30 to be rooted (August 2018 vs May 2018 for all the others) because T-Mobile removed most of the fastboot flash commands.
@runningnak3d had to create a process to get TWRP onto T-Mobile H932 and root it.
See link above. It's CLEARLY labelled "Root H932". IF you happen to go to the WTF instructions thread (the way to root all the other V30), I also have a link pointing to the ROOT H932 thread for T-Mobile H932 users.
Did you not search this forum any?

Was not aware of this. I'm kinda new at this so I didn't think to search specifically for the T-Mobile version. Thank you for the link.:good: I appreciate it.

Need help installing recovery on XT1526, it's just not working, tried all the methods

EDIT: ALSO, use usb 2.0 ports to flash stuff, usb 3.0 is not working 100 percent yet.
EDIT, 14 Mar 2016: Kingroot got me to root and now I have twrp installed, http://www.kingroot.net/ .
I have a Sprint prepaid Moto E 2015 LTE, XT1526. I did the motorola bootloader unlock, that went fine.
The phone works and is activated on RingPlus, when it boots, I get the Red Warning, Bootloader unlocked, when normally booting.
When I try to flash a recovery to the phone (all that I could find here on XDA), I get this response:
S:\Phones\Moto_E-2015-2ndGen-XT1526\adb-and-fastboot>fastboot devices
TA0XXXXXXX fastboot (edited to take out SN)

S:\Phones\Moto_E-2015-2ndGen-XT1526\adb-and-fastboot>adb kill-server
I've tried everything, and am providing as much info as I can, in case anyone seeing something that is 'new' or 'different' about my phone.
Double check and be sure you're attempting to flash the TWRP for the Moto E 2015 LTE "Surnia", not "Otus" (which is the Moto E 2015 3G). iirc, I used Squid's TWRP from here: http://forum.xda-developers.com/moto-e-2015/development/twrp-squid-twrp-recovery-moto-e-lte-t3137649 . If 3.0.0 doesn't work, try 2.8.7.
You should also try changing USB ports. I ran into a similar issue where I wasn't able to flash things when I plug into my most often used USB port. I suspect that the contacts got worn from how often I used it, so I tried another USB port and it worked fine.
I have done same procedure as yours and meet same problem yesterday.
I flashed twrp recovery with following command,
fastboot boot recovery.img
instead of
fastboot flash recovery recovery.img
here are the post which I followed.

I know that, does not help. I've tried that recovery, one from cyanogenmod also, the recovery img is not the problem. Thanks anyway.
go to phone options and turn on USB debugging and when you go to flash it..
- turn off phone.
- hold volume down and power to get to boot loader screen..
Leave it there and connect to PC.
It should be showing you the bootloader screen.. you know what that is right ?
Then open "Minimal ADB and Fastboot" install folder..
Right click empty folder space while holding shift key down..
Select open cmd window here..
type in either,
fastboot devices
or
mfastboot devices
and make sure it says your device is listed
then paste into cmd window..
mfastboot flash recovery recovery.img
make sure your new recovery file has that name and is copied to that fastboot folder.
that should be it..

Can a DEV please help ? If I need to go back to stock I'll be glad to do it and then unlock the bootloader again, however, I've posted in two diff forums trying to get someone to tell me the correct SPRINT img to bring back to stock, no answers.
XT1526_SURNIA_USC_5.0.2_LXI22.50-29.1_cid9_subsidy-DEFAULT_CFC.xml
XT1526_SURNIA_REPW_5.0.2_LXI22.50-56-1.1_cid6_subsidy-REPUB_CFC.xml
XT1526_SURNIA_BOOST_5.0.2_LXI22.50-14.8_cid9_subsidy-DEFAULT_CFC.xml
I think it's the boost, but it doesn't have the SPRINT label on it, like my phone.
You just said,
"Can a DEV please help ? If I need to go back to stock I'll be glad to do it and then unlock the bootloader again"
So why would you say that ?
Did you relock your bootloader ?
Maybe that is why you are having a problem ?
I never have relocked mine eh..
And i have had no problem flashing TWRP from Squid.. all his various updates overwriting the old one.
I have flashed a bunch of stock retail recoveries too and all of those worked fine too.
I am curious did you try and load recovery after to see if it actually changed or not ?
EDIT:
Can i ask you exactly what Custom Recovery you are trying to install ?
And did you verify the MD5 hash ?
I always do *if it's available..

Maybe that is why you are having a problem ? No

I've done all those things and tried to post as much info in my OP. Is there a Dev that can help me?
I've now tried to go back to stock in an effort to unlock this biatch using XT1526_SURNIA_BOOST_5.0.2_LXI22.50-14.8_cid9_subsidy-DEFAULT_CFC.xml, and it wont let me do that either. It's not letting me write to the GPT partition. This leads me to believe my phone is NOT unlocked, even though the bootloader shows UNLOCKED BOOTLOADER. Anyone know an answer?
I noticed something a while back when I attempted to flash recovery on a different phone (nexus 6) but failed. I tried a bunch of stuff to no avail. The solution was to simply get a new set of platform tools because mine was too old. Doesn't hurt to try.

Thank you for trying. I just found a post, (and now I can't find it), but the guy went through what I did, and then he used KingRoot, http://www.kingroot.net/ , and it worked.
So, I tried it too, and magic, it worked. I now have root and TWRP installed.
I could have sworn I tried KingRoot, but it must have been on another phone I had.
Are you sure your recovery file is called recovery.img and not twrp.xxx.img? If not you need to rename it
Another problem I had, I was using a USB 3.0 port on my computer. This is a not the way. Using a USB 2.0 port works on flashing stuff.
Hi faheyd, I also have XT1526 on android 5.0.2, but kingroot fails. I was told not to update OS to keep it working in India.
Doess ur phone run on 5.1?
Does USB debugging needs to be activated?

Does this method work with firmware ver S029. I am already rooted with kingoapp. But Flashfire app shows boot loader partitions to be protected . I suspect bootloader to be Locked. In such senario will this method work or will it brick my phone.
I also have another question if flash TWRP recovery on locked bootloader anyway, will it only fail to boot into recovery mode or will device fail to boot normally altogether
and it does boot normally then if i reflash stock recovery back on locked bootloader will that fix the issue of booting into recovery mode.

This method will work ver S029 also. To flash recovery you need unlocked bootloader.
Well, I'm getting an error - (remote: not allowed), every time I try to boot the recovery.

This link gives you stock firmware. I too have deleted my backup but used it to get it back. But however I faced problems like boot loop many times and even IMEI turned 000000000000000 for both sim slots but still it was recovered by using "MTK Engineering Mode" app which you can get from "Play Store" and follow the following steps.
Step 1) Open the the MTK Engineer mode app and swipe left side to go into Connectivity.
Step 2) In the Connectivity click on the CDS information.
Step 3) And then Tap on the Radio information.
Step 4) Then you will be able to see Phone 1 and Phone 2
Step 5) Just click on Phone 1 first. then enter the Command as AT +EGMR=1,7,"your first imei" (Put a Space between AT and +, Like AT +EGMR=1,10,"your imei") and then tap on SEND AT COMMAND it will show you that command sent,
Step 6) Now press back button and Tap on Phone 2 (if you have a Dual Sim phone) and Type AT +EGMR=1,10,"second imei" and tap on send at command.
Step 7) Now Just Restart you device and enjoy now Sim Card will Display the Network in the status bar.
And you are done!!!!!!!!!
You can see your IMEI by pressing *#06#
If you face boot loop problems again and again please inform me.
Just the problems I faced. They are the solutions. Please do reply to this message.
Okay thank you. I will try it. Thanks a lot

You can also root Lenovo Vibe P1m using SP Flash Tool. I've done the same and changed recovery from stock to TWRP easily without using any commands. Device works flawlessly and currently have installed MiUI 8 custom ROM.

Fastboot command given for flash recovery is wrong.
The right command is
Fastboot flash recovery recovery.img
Second recovery is the name of your recovery. If your recovery name is twrp then command is
Fastboot flash recovery twrp.img
Guys... If your device is new version (s036 pre installed) , use TWRP3 only.

Help please?????

Hi all,
Today I tried to root my LG G5 H830 but with an older method for Marshmallow(in the video i was watching the version wasn't even specified so I was unaware and I believed that the version of the phone did not really matter). I proceeded to follow this man's instructions @: "How to Root T-Mobile LG G5!" by "Max Lee" on Youtube(as a new user i cannot post links ) I unlocked my bootloader, got drivers and followed his instructions up onto an error on LGUP. Basically the error's purpose was to tell me that Nougat is not supported. So I had no choice but to reboot my phone and go through the android initializing setup.
After realizing the error of my ways I then found this post here via Google Search: "Install TWRP Recovery and Root LG G5 on Android Nougat | DroidViews" to install TWRP. Now my bootloader is unlocked and I have no root. The only problem here is that whenever I go into developer options and try to toggle 'OEM unlock' on it won't let me. The OEM unlock setting is grey-ed out and I am unable to toggle it!! This is what I need help with! Although my bootloader is very much infact unlocked I think some error occurred to where now I cant toggle my OEM unlock thus I am unable to flash a TWRP recovery via fastboot!
If I reboot into my bootloader and run the command "fastboot flash recovery recovery.img" i get this:
Code:
target reported max download size of 536870912 bytes
sending 'recovery' (18668 KB)...
OKAY [ 0.419s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time: 0.435s
I even ignored the error and tried to boot into recovery manually and i just get the stock recovery.
Please help me guys
What about locking the bootloader again and unlocking it after that with the newer video you used?

I proceeded to follow this man's instructions @: "How to Root T-Mobile LG G5!" by "Max Lee" on Youtube(as a new user i cannot post links ) I unlocked my bootloader, got drivers and followed his instructions up onto an error on LGUP. Basically the error's purpose was to tell me that Nougat is not supported. So I had no choice but to reboot my phone and go through the android initializing setup.
After realizing the error of my ways I then found this post here via Google Search: "Install TWRP Recovery and Root LG G5 on Android Nougat | DroidViews" to install TWRP. Now my bootloader is unlocked and I have no root. The only problem here is that whenever I go into developer options and try to toggle 'OEM unlock' on it won't let me. The OEM unlock setting is grey-ed out and I am unable to toggle it!! This is what I need help with! Although my bootloader is very much infact unlocked I think some error occurred to where now I cant toggle my OEM unlock thus I am unable to flash a TWRP recovery via fastboot!
If I reboot into my bootloader and run the command "fastboot flash recovery recovery.img" i get this:
Code:
target reported max download size of 536870912 bytes
sending 'recovery' (18668 KB)...
OKAY [ 0.419s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time: 0.435s
I even ignored the error and tried to boot into recovery manually and i just get the stock recovery.
Please help me guys

Did you try to run the terminal/cmd as an administrator/root?

Recover H932 with stuck boot

Anyway to recover my device that:
Fastboot accessible
Lost twrp
Download mode doesn't seem to work (it restart itself after 15 second or so)
Stuck on Tmobile bootup
Was trying to install exposed
factory reset > flash 20o > flash framework
Now can't seem to get it to boot up
Try to use fastboot to flash twrp
C:\adb>fastboot flash recovery twrp.img
target reported max download size of 536870912 bytes
sending 'recovery' (30860 KB)...
FAILED (remote: unknown command)
finished. total time: -0.000s
try fastboot update.zip
C:\adb>fastboot update update.zip
archive does not contain 'android-info.txt'
error: update package 'update.zip' has no android-info.txt
LG Up does detect device, but trying to Refurb or anything will get stuck at 4% waiting for device
Thanks

If you have T-mobile H932 you do not have fastboot flash commands. You can boot into fastboot, but it's basically useless.

T-mobile H932 does not have fastboot flash commands so you can't use fastboot to install TWRP with fastboot. That's the whole reason @runningnak3d had to create a whole new method -- using a Linux boot flash drive while on 10d Nougat -- to get TWRP onto T-mobile H932. You know this if you rooted your T-mobile H932!
You will have to do that all over again if you really lost TWRP.
The T-mobile H932 is a standalone island unto itself and is the hardest V30 variant to install TWRP on and root. All the others use the WTF method.
This and another reason is why only T-Mobile customers should use T-Mobile H932.

Especially if you updated to Pie KDZ/TWRP-flashable zip, make sure you are using the latest Dev Patched LGUP from T-mobile H932 Pie KDZ thread. Any earlier dev patched LGUP will only work on Oreo or lower. Follow the installation instructions, be sure to UNinstall any prior versions.

Well, you can still use H932 fastboot to unlock bootloader. And no hoops required to do that. And that's just about the only good thing about H932 ?
sadly, it was a year ago. I've noticed that installing xposed is dangerous as flashing custom rom even using magisk module, it sometimes make your phone boot loop, or fail to boot at all. any emergency tools such as Recovery, Laf download mode, should be present on their phone (at least one)
