Have you tried flashing the complete stock firmware via e recovery?
When you are on the "can't be trusted" screen you get this option.

There is no working TWRP for EMUI 9. TWRP is only for EMUI 8...
Try to reflash original recovery_ramdisk.img with fastboot.

Honor 5x unable to boot

So I have a problem with my Honor 5x (KIW-L24) after doing an ota update with twrp (silly me). So I tried options already suggested on these forums, like getting back into twrp and fixing my stock rom, but the problem is, for some reason I don't have twrp anymore. I've been trying to get into fastboot to fix this mess via the platform tools, but the only interfaces I'm able to access are the broken "Honor for the Brave" boot logo and an EMUI logo that's stuck at 0% saying "Huawei software installing DO NOT unplug usb or press any key!" which I assume is the stock recovery which replaced twrp. Is there any way I could access the fastboot menu or am I out of luck?

the bootloader screen is white and says fastboot on it
unplug the phone / power off / hold volume + and volume - and power you should get to stock recovery and you can choose to boot to the bootloader
If the OTA is on your ext_sdcard remove it before trying to boot recovery

Guide to return back to Indian Stock (C675) on V10 from any Custom ROM

Many of us are on custom OS and want to return back to stock Indian OS which was not possible till now. Below posted is a tried and tested method by me as well as my friend @ankan1993.
I assume you are unlocked BL and your device is atleast not bricked.
Please follow this guide step by step to get a stock working device. This is for Honor V10 Indian Version C675 and I'm not responsible for your loss if you make this worst by trying this on other variants/models or if you choose not to follow this guide properly.
I assume you are on Berkley TWRP with the latest version, unmodified one.
Downloads : (Keep both in your fastboot folder in PC)
Stock Recovery : https://drive.google.com/file/d/1WEUHRrba1dV3109e7h7b3Hp_aJhy0vM8/view?usp=sharing (stockrec.img)
Stock System Image : https://drive.google.com/file/d/1IABtk7HJ9ml6kOpytYHrnT6z3C1_9IfW/view
1. Enter TWRP and go to wipe -> Advanced -> Select system and data, and wipe them.
2. In TWRP, go back and Click Reboot button on main screen and reboot to Bootloader.
3. Connect you device and open cmd_here (open as administrator) from fastboot folder. ( I assume fastboot is installed and working in your system. You can check by the command "fastboot devices" . Device should show there. )
4. Type "fastboot flash recovery_ramdisk stockrec.img" (It should complete without error)
5. Once completes, Type "fastboot flash system system.img" (This may show error like "Invalid sparse file format". Ignore that and keep waiting for 10-12 minutes until the system gets flashed completely.)
6. Once it gets completed, disconnect your device and then press Vol up + power, until it screen shows stock recovery.
7. In stock recovery, use factory reset and cache wipe option one by one and then reboot.
Hit thanks if you think it helped :fingers-crossed:
Finally, after days, after being tormented by the bugs of custom Roms we have something to cheer about. Kudos Oreopie! Cheers to the long hours.
Kudo's bro.. appreciate your efforts :good:

Obviously warning screen will come up, but at the same moment you have to just leave power button and keep on pressing vol down button, until you get into bootloader mode. It takes time bro and let me tell you one thing, no matter which mode you boot, no matter what ROM it is, once the bootloader is unlocked it implies that the unlocked warning screen will show and then it will be allowed to get into whatever mode you wish.
Try it as I told, be patient and follow the same guide exactly if you do not wish to visit service centre. There is nothing wrong happening with you other than an improper method being followed in haste

Because on custom you are on 8.1 and twrp doesn't support yet.
May be you can try dload the b161 version which is out on firmware finder now.

Invalid sparse error happens when trying to flash .IMG files in Windows system.
It can be easily solved by using Linux system.
thanks for the reply

Bootloop

WHAT SHOULD I DO??
So, i used openkirin the wrong way and now TWRP is frozen and the openkirin thing is bootlooping. I try to flash TWRP again but it comes up with failed- command not allowed. WHAT SHOULD I DO all i can do is go into fastboot, eRecovery and download mode, which I tried to use but it says failed, so the the wifi eRecovery.
EDIT-
Now the phone tries to boot then brings itself to eRecovery mode. O2 says that they cant do anything. Could i send it to a service centre? I NEED HELP!

Tried to Unlock Pixel 2 XL Now Stuck in boot mode!

Hi guys,
I think I made a huge mistake Any help appreciated...
I was following the Magisk and TWRP guides to try and root my phone. I thought it was all going well, but then when trying to flash TWRP, it didn't let me flash it to recovery, it said 'no partisan'. I found on a forum post to try the command 'fastboot getvar current-slot' (this returned a) then 'fastpool flash_a twrp.img'.
I tried this but then TWRP got stuck on the loading screen. I then realised that I couldn't boot into my Android version anymore as I'd flashed TWRP directly onto the boot partition! So I went about trying to flash my stock Android version back onto the phone... I then did this:
'fastboot boot_a boot.img' I stupidly then rebooted. I now am stuck with a perpetually spinning Google loading boot image. I can't launch into recovery mode as I have none, and when holding the power button and volume up it shows an info screen saying "PRESS POWER BUTTON TO PAUSE" and then it goes to the perpetual loading screen again.
I also can't do any more fast booting because adb cannot connect anymore...
Am I completely doomed?

I ended up eventually un-bricking my phone by booting into safe mode and re-connecting the ADB. I then successfully ran 'flash-all.'

fail to open recovery_cause(No such file or directory)

Hi All
I have samsung A5 2017. When i start my phone it shows no command and it continues to restart after 1 minute.
When i try to open recovery mode i get error "fail to open recovery_cause(No such file or directory)". I have also tried combination of key power and volume up but not getting recovery mode. I think it has been deleted or something else. I am also unable to load firmware.
I also tried to install twrp with odin 3.13 but get error unable to install frp locked.
Please tell me solution how can i get back recovery mode so that i can install firmware.
Please help me for this.
Hey there,
I have a similar issue and I can see your post dates back to 2020. Have you ever found a way?
I'm very curious about solving the issue on mine (I can't reboot at all, can't even access the reboot after getting the "no command" message. If you have any clue on how you accessed reboot mode and can be kind enough to share, this would be really appreciated )
I know this is an old thread, but did you find a solution?
On an unlocked J6, after flashing the stock rom, although I can open recovery, I get the same message. The options I tried (both reboot options, both wipe options, power off) work. I went ahead and installed twrp through odin, which passed, but when I boot into recovery, it boots into samsung recovery (with the same message) and not twrp.
I'm guessing the twrp problem is related to the error message.
