Can't boot into recovery - HTC One A9

Hi everyone,
I recently installed Nougat on my hiaeuhl device, so I'm unrooted. I would very much like to root it, so my plan is to install twrp then flash a SuperSU from TWRP.
The problem is that I can't boot into the TWRP recovery. I do the normal process
Check the device -> adb devices
reboot into download mode -> adb reboot download
Flash the recovery -> mflashboot flash recovery twrp.img
Reboot -> mflashboot reboot
I then get the message, written in red, that I can't boot into the recovery. I tried this with multiple TWRP versions (2.8.6, 2.8.7, 3.0.2, 3.0.4) but to no avail. Finally I gave up and flashed a stock recovery image, which works.
My questions:
- is there any way I can flash the SuperSu without TWRP?
- Is there any way I can make my phone boot with TWRP, so I can flash the SuperSu?
Thanks and cheers

Can you boot into the recovery? Or fastboot? Also before trying to install a new ROM did you backup your previous?

Can't boot into recovery mode, maybe something went wrong while updating TWRP to 3.0.2 but can boot into fastboot.
also had backup of previous rom but since i can't boot into TWRP now so can't restore it. Earlier on TWRP 2.8.6 i was getting zip file execution error while restoring/installing new ROM.
So for now i have only access to fastboot mode, how to proceed futher?

You have 2 options you can flash the stock rom and recovery via fastboot here is a guide http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541 (Just skip step 4 don't relock the bootloader specially if you want to install TWRP) Make sure you download the correct file there is a 64gb and a 16gb listed in this guide or you can download the stock file straight from cynogen OS here https://cyngn.com/support
Or you can reinstall TWRP via fastboot by downloading TWRP here https://dl.twrp.me/bacon/ and install your backup if its still there. If its not there you can either download and install any custom rom you want or if you want the stock rom go with option 1 above and then re-install twrp. (Always remeber after installing TWRP don't fully boot into the system or you will loose TWRP, boot straight to recovery once its done flashing TWRP by holding the power button and volume down. )

[Solved][C2105]Can't install custom recovery with anything contanining FOTAKernel way

Only thing is works for me is https://forum.xda-developers.com/xperia-l/orig-development/cwm-recovery-installer-t2589320
su into dd via adb, twrp app, recovery installer by corphish (https://forum.xda-developers.com/xp...-installer-t3187915/post62536810#post62536810)
Every "fotakernel"-style ways saying that it is finishes its jobs successfully, yet when I "adb reboot recovery" it always loads stock recovery.
Bootloader is unlocked, I've checked it via *#*#737...
I've spent over 8 hours trying everything I've found to flash img, but it just doesn't becomes custom recovery, it is always reverts to default.
What I'm doing wrong or what is wrong with my phone?

IIt's not your fault, it's because stock ROM only supports and allows this recovery!
So if you don't have any problem, use only that one!
But if you want to install custom ROMs using latest TWRP, then you have two choices:
1- Install some Lollipop ROM from current recovery and then use its own recovery to update your recovery to latest one, and continue your works!
2- Use adb & fastboot to flash latest TWRP to BOOT partition (not fota or recovery partition!!!) by booting into fastboot mode and using this command:
Code:
fastboot flash boot [I]yourimagename[/I].img
So it directly boots into recovery( instead of ROM!) But be careful!!! You must install your new ROM right after recovery is opened to avoid any potential problems with missing boot!
I recommend using first method for your convenience and safety

Thanks, that helped me so much!
Okay, just reporting how stuff worked for me
Flashed boot.img from cwm11 - flashed cm11 = 4.4.4
TWRP to FOTAKernel didn't worked - still old CWM
Installed CM12 from that CWM - 5.0 as you mentioned.
Tried TWRP to FOTAKernel using su+dd. Still old recovery (don't remember which one, probably same CWM).
Decided to go all-in, flashed TWRP img to boot using fastboot - Finally got TWRP, but obviously couldn't run anything else. Also had flickering\shaky screen left and right but it's functions seemed to working alright.
Flashed [7.1.1]LineageOS 14.1 || Beta 4 by corphish (I've tried to flash it before from that old TWRP (2.7.10) it would run once (all functions were working fine), after you reboot device it gets stuck in bootloop.) result = everything works, no bootloop after restart, and TWRP 3.0.2.0 either fixed it self or maybe it comes with ROM so that helped, dunno.
Thanks for mentioning "fastboot flash boot yourimagename.img" and that I can flash recovery into boot.

Glad that it worked for you and you finally could get latest one!
I forgot to mention that in first method, after installing LP ROM, install recovery installer app and flash TWRP v2.8.7.2 and use that to install latest one !!! and LoL very long way
I just wanted to say that it is possible!

What's New(?) procedure to install Custom ROMs coming from OOS 9.0.5?

Hello guys,
I'm having trouble trying to install a Custom ROM (Tresk Mod, but I get it with others too)
So basically some days ago my whole Internal Storage got encrypted so I had to a full wipe.
From there I decided to use Msmtools just in case, so I got back to OOS 5.1.5 from there I updated to OOS 9.0.5 via OTA and unlock the bootloader and install TWRP everything works fine.
But when I tried to install any custom ROM I either cannot boot and just boots to Bootloader (Not even the recovery works) and I get "Failed to load/authenticate boot image: Load Error" which I can fix fastboot flashing all the partitions...
Or I straight get a black screen with the White Notifications LED whenever I try to boot either to system or recovery and from there I can only recover using Msmtools...
So I'm now asking, what are the steps for flashing Custom ROMs now?? Because seems like I'm doing something wrong since I'm ending having a Bricked device...
try to flash rom with bluespark recovery
Nothing changed that I'm aware of, but I found that I'll have the same experience if I try to root before booting the system at least once rootless first. Also, I have issues like that whenever I keep TWRP (even Blu Spark) installed. Now I only use it via sideload every time. I never have issues anymore.

I did the following:
1. Upgraded from 5.1.5 to 9.0.5 (Since I was coming from Msmtools fix)
2. Unlock bootloader
3. Reboot to system and then boot again to bootloader for doing (fastboot boot TWRP.xxx.img)
4. Once in the recovery flash recovery and Magisk (just because) and back to system (where everything was working perfectly)
5. Rebooted to recovery and did the following:
Factory Reset (The one that you slide which should wipe Cache, Dalvik and Data)
Flashed the ROM (HavocOS 2.5) and right after that TWRP
And at this point I tried to reboot back to recovery but black screen and cannot boot to recovery nor system not even via fastboot
Is your order different? Am I missing something?

Agreed. Always reboot from recovery to recovery after flashing a new one (TWRP). THEN, go ahead and flash gapps and magisk.

I finally figured it out
The problem was that as I was updating via OTA OOS 9.0.5 was only installed in one Slot so I need to install it in the other as well.
Did the following process:
1. Boot to Bootloader and do "fastboot boot TWRP.img"
2. From there flash TWRP.zip and Reboot back to it (Recovery)
3. Flash OOS Latest (9.0.5)
4. Flash TWRP
5. Reboot to TWRP
6. Flash OOS Latest (9.0.5)
7. Flash TWRP
8. Reboot to TWRP
9. Wipe data, dalvik cache
10. Flash ROM
11. Flash TWRP
12. Reboot to TWRP
13. Flash gapps + Misc (Magisk, etc)
14. Boot system
Technically just one 1 installation should do as the other slot was already populated but the twice just to be safe.

Oneplus 7 Pro Bootloot

Hello, So i tried to install GPS joystick privacy mode app as a system app first thru titanium backup then ..., i rebooted and now im on boot loop, what do i do?
Any help is appreciated, Thanks
{Mod edited}
Hold Power + vol up + vol down for several seconds should put you in bootloader. Or alteranately, Power+vol down for several seconds should send you to TWRP if you have it installed. From there, I'm thinking you may need to flash the stock ROM again, since you were messing with the system partition, and the phone is not booting now. Either flash stock ROM in TWRP, or use the fastboot stock ROM.
I didn't have twrp installed and i still dont, i patched the boot image with magisk and all i have is root cause i cant seem to keep TWRP installed after 9.5.3, im currently on 10.3.0

You should be able to fastboot flash stock boot.img from the fastboot ROMs to get the phone running again: https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
This will unroot the phone. But you should be able to easily root again by the method you did originally.
What is the problem you are having with installing TWRP? You haven't specifically described how you tried to install. I've had no issues using the TWRP installer zip, after multiple updates.
You need to re flash stock so, boot lastest twrp (fastboot boot twrp.img) and flash lastest stock rom.
And if you need an app as system use magisk module App Systemizer (you also need busybox module and Termux app from playstore) this is the only way (that I known) to convert user apps to system

tried that first part too, cant get into twrp and that makes sense now, i installed busy box but never opened the app to install to system/xbin
here's how ive done my part so far.. ever since i bricked my device last feb 24 , rendering it totally unresponsive.. that not even vol up & power button dont work
1. had to use msm tool just to boot my device. successfully boot my device to 9.5.3
2. device seemed to have a locked bootloader again so i un.lock it again. downloaded a patched 9.5.3 boot.img and flashed it via fastboot
3. successful root confirmed..
4. downloaded twrp 3.3.1-75 unofficial installer.. about 17.5mb. flashed it thru magisk as a module.. then install magisk ( as recommended) then reboot.
5. after a reboot.. and setting it up to my liking,, i reboot to twrp to flash the latest 10.3.1 stable rom..
6. flash twrp installer again.
7. hit reboot then choose Recovery . phone reboot to recovery again
8. flash magisk.zip which i downloaded earlier. then reboot.
done
updated to 10.3.1 with magisk & twrp intact..
btw.. i really dont know how to force my phone to reboot to twrp via PC ADB fastboot command.. easiest way for me to install TWRP is by flashing the TWRP INSTALLER as magisk module

That is because that is NOT the correct way to install TWRP img. You need to fastboot boot TWRP, then once in TWRP flash the TWRP installer zip, as I already mentioned.
This is described in the TWRP dev's thread (and you will see no mention of fastboot flash TWRP).
https://forum.xda-developers.com/on...nt/recovery-unofficial-twrp-recovery-t3931322
Also make sure you use a current version of TWRP (latest is unofficial -76) which you can get from the above link.

i just simplified it as magisk mod.. but in TWRP THREAD,, its named by maoronofrio as TWRP UNIFIED UNOFFICIAL INSTALLER
and it can only be installed by installing it as magisk module

Twrp boot loop

I patched twrp img with magisk and then ran fastboot flash boot "patched file" in fastboot mode. Now, whenever and however I start my system I get only the twrp menu. My device is Lenovo tab 4 8(tb-8504f)
Re-flash tablet's Stock ROM to get rid off of all modifications you applied so far.
re flash the ROM. dont flash the magisk or twrp after it. you will be saved.
you can use twrp via adb boot twrpxx.img So flashing it not needed.
Magisk installation has now become trickier simply flashing via recovery won't work

hello thanks for replying. Could you provide me with the official rom. I've found one but not sure how reliable it is. I also in the twrp menu installed the patched twrp image from sd card to boot. After rebooting I again get the twrp menu but the file is not being show in sdcard anymore.
