Issues with flashing TWRP on S-Off GPE M8

Every time i flash the latest TWRP for the HTC One M8 GPE on the newest update 6.0.1 June security update, when flashed in fastboot, once it completes, it will automatically boot into twrp, i select the option to allow system modifications, and when i reboot into system it boots just fine, but when booting back into the bootloader, and into TWRP I'm greeted with this screen.
any help would be appreciated, i tried searching the forum, but had no luck finding anyone else with this issue

Because you use command
fastboot boot NameOfTWRP.img
To correctly install TWRP, use command
fastboot flash recovery NameOfTWRP.img

Thanks for the prompt reply!, I'll give it a try when i get home!

So i had success flashing TWRP properly, and can now boot into it, back up my OS etc, however, when i flash the latest version of chainfire root via TWRP i get a boot loop every time, I'm wiping the cache after preforming the flash, have any ideas what i might be doing wrong?

What version number SuperSU are you using exactly? A lot of times, folks use what they think is the "latest", but when asked what version number, we find out its not even close to current (which has the common result of bootloop).

Issue when flashing TWRP

Hi guys
I am trying to install the latest TWRP, but every time that I try to boot into recovery through "adb reboot recovery" the phone restarts and I see the android maintenance logo.
What I did up to now:
1) I unlocked the bootloader following LG site instructions successfully. I have the bootloader unlocked message.
2) Downloaded TWRP to my windows PC for H815. After doing "fastboot flash recovery twrp-3.0.2-0-h815.img", the result seems to be successful as I get the expected OK message.
3) I try to reboot to TWRP through "adb reboot recovery" but every time goes to the maintainance logo. I tried also the button combination but I cannot see the Factory Reset menu or the TWRP menu.
Just to mention that I was completely stock V20d without root at the beginning and that the phone boots fine for the moment.
Please help.

No one had my issue? I am still trying to install TWRP and I only manage to boot it temporarily from the PC..

twrp needs to be flashed from within twrp. First boot twrp:
> fastboot boot twrp.img
Now you install the image as recovery.

I think this was the first issue, but after I should also remove the "read only" from TWRP in order to keep it in the recovery.

Not quite right. You can flash twrp image from twrp recovery. No need for a zip.

[HELP] Unable to flash Stock/TWRP recovery or Any ROM via FASTBOOT(bootloader)

I was on OOS community build 3.5.3 with modified twrp-3.0.2-19-oneplus3.
I wiped everything except internal storage after that I tried to flash official TWRP.
After installing official twrp via modified TWRP. Niether I can boot into my recovery nor able to install any recovery via fastboot.
it I use "fastboot flash recovery recovery.img"
after installing recovery with this command My bootloader get stuck then I have to again restart my bootloader.
please help

You're probably stil on 3.5.2 firmware which isnt compatible with official twrp. Try and get into fastboot and try flashing modified twrp again. Then reboot in recovery and flash 3.2.6 firmware (not the rom) from modified twrp. Then reboot and flash official twrp from recovery or in flashify app.

i had this problem the other day, fixed this by flashing the modified recovery from a post here turn it off the booted it up by holding vol down + power and somehow it worked i was able to go into twrp

Can't install TWRP on Oneplus3

I'm having trouble installing TWRP on my Oneplus 3.
I can install it fine through Fastboot, it installs without problem.
But when I actually want to go to the recovery menu (by selecting it in the bootmenu), the screen flickers briefly and I'm returned to the bootmenu.
However, I have found a way to boot TWRP.
When I use the All in One Toolkit, there is the option "Flash TWRP AND Boot it".
This way I can get in TWRP, but as soon as I reboot, I'm having the same problem..
Has anyone experienced this before or know what to do?

Never experienced this problem. But are you sure that you use the correct version of TWRP for your ROM?
And did you try not to flash it via fastboot but just boot it? The command is
fastboot boot recovery twrp.img

yes even i had this issue once. i used to get a black screen when i try to enter recovery mode.but later i flashed modified twrp file. And its working fine now.
and try this while trying to enter recovery after installing through fastboot.
fastboot flash recovery twrp.img
fastboot boot recovery twrp.img

M8s stuck in bootloader

Hello everyone. I got a M8s from a friend wich is stuck in bootloader. The recovery didn't work at the begin, so I flashed twrp-recovery-2.8.6.0-m8s-qlul.img (flashing recovery using htc_fastboot.exe flash recovery theimagename.img) and it worked, then I tried to install a custom ROM Android_Pandora_Rom_1.2_(Discontinued).zip wich went all the steps fine until: Optimizing applications 8 of 204..then phone shat down to black screen. I booted back to bootloader, recovery, wiped and go for a new install, same issue.
After that, I was going to install lineage-13.0-20170715-UNOFFICIAL-m8qlul.zip where the developer of this rom recommends twrp-3.0.2-0-m8ql.img so I tried to flash it (flashing recovery using htc_fastboot.exe flash recovery theimagename.img), then tried to acces recovery, brings me back to bootloader so fast, rebooted bootloader, tried again, same problem. Tried the fasboot erase cache, no help.
The Hboot state is Unlocked and the S is ON. I tried some other recovery images, as stock_signed or 3.0.1, tried the one from M8 ToolKit but all failed and I still can't access recovery, everyting I do, it brings me back to bootloader. I did htc_fastboot boot recoveryfile.img wich works, but useless, the dd if= method to set the recovery permanent load did not work after reboot, /data and /system can't be mountet, it seems the "boot recovery" option is 99% readonly.
Any advice, any help please? It would be much appreciated! Thanks in advance!

Hi McBad,
you could try the following. I also had some problems to access the recovery.
- Again bring the phone into fastboot, flash the 2.8 recovery and access it
- Do a wipe for factory reset, not just only cache
- after that try to flash the twrp-3.0.1-0-m8ql.img version, the other one worked for me neither
- the try to install the custom ROM LOS13
I hope this will help you.

It would be great if that would work, but flashing a recovery does not work. I flash it, success message, try to access it, vibrates and bootloader pops back instantly. That is the problem.

Sorry for double post, but can anyone help me with this? This is the second day I struggle to make it work. Any chance to make the hboot locked again? It didn't work with oem lock command. I would like to lock it so I can put an official zip on sdcard so the hboot to restore it to factory stock, some RUU. Or get it s-off so I can flash a rom from fastboot? The phone does not have any ROM on it, image crc results system 0x0, recovery 0x0. Please, help!

Have you tried sideloading twrp ?

Did you use HTC fastboot ?

Yes, I used htc_fastboot. Use sideloading? Like boot the img file directly? Tried that too.

Is there any way you could flash twrp 2.8 again? Once in that recovery you have sideloading option which you could use to transfer latest recovery onto your device. Are we talking about the same process?

You can't install lineage if you haven't upgraded your device with latest official update. I would try reinstaling twrp 2.8, do a wipe of cache, dalvik cache and system, Sideload CM 12; and see how it goes. As well, while in twrp I would try relocking bootloader but only after an unsuccessful attempt to flash said rom. I don't know what your experience with soft bricked devices is, but sometimes it takes a while, different usb cable or usb slot on your PC, correct files in adb folder, re-download of rom or recovery because it easily gets corrupted while downloading. And obviously a fully charged device. Let us know how it goes.
