[Q] Stuck at HTC logo Can't enter bootloader - One (M8) Q&A, Help & Troubleshooting

UPDATE: I have managed to get to the actual Bootloader now after figuring out I was doing the volume button trick wrong. I am now at the bootloader but can not enter recovery, I have had TWRP last installed but can't seem to access it now

Flash twrp again

Remember the new versions of TWRP don't work on an older bootloader so if you're using 3.16.0000 you'll need TWRP 2.7.x

Unable to flash custom recovery

Hi,
I have the Find 7 with the new display panel.
I wanted to flash the latest version of TWRP but failed. I do not know what I did wrong.
I can use adb and fastboot without any problem. When trying to flash recovery, it says there that the flash was successful but when I reboot to recovery, TWRP was not installed and the original Oppo recovery is still there.
The bootloader is unlocked. And I tried relocking and unlocking again but to no avail. Whenever I use the command "fastboot oem unlock", nothing happens to the phone.
I am currently on spectrum. I want to try other roms such as the lite COS 2.15 and also maxwen roms since that only those supports the new panel.
I am also trying to get root for my phone and it is impossible without custom recovery.
Thanks for any help.
I had poop loads of issues with getting custom recovery on my Find 7a. Eventually I used these instructions:
http://community.oppo.com/my/forum.php?mod=viewthread&tid=996
They work. Don't know if it's the versions of ADB or Fastboot or something.
Give it a go

I will give it a go when I get back. Thanks!
This is what a forumer from the official forum said and it works:
After you had successfully flash recovery via fastboot, you MUST NOT reboot the device. AFAIK, if you reboot the device it will restore the recovery back to stock oppo recovery.
So instead, you need to immediately press vol down & power button on the fastboot screen. Keep holding the button until you see the TWRP recovery screen. Hope that helps. Cheers!""

Unlocking bootloader erases data?
Mine wouldn't flash recovery. It said successful but I still had oppo recovery 1.2 and it only worked when I found the latest official twrp over version 3. after flashing, I disconnected usb and then held down power button to shut the phone down. It then was able to boot to twrp ok.
I used the latest one.

Only fastboot works on my zenfone.

Hi. I'm terribly lost.
I bought a ze500kl (z00ed) and played around with root, twrp and marshmallow. The last thing I did was installing marshmallow and then I wanted to flash twrp.
What I ended up with is a phone which you can't boot, you can't get into recovery and I'm not even able to flash any other recovery than the stock one. And even if I flash it 'successsuccessfully' I'm still not able to boot into it.
Code:
fastboot reboot-bootloader
yields the phone starting back into fastboot mode.
As far as I understood my bootloader seems to be locked.
How can I get my phone working again?
The command fastboot reboot-bootloader only boots you into the bootloader, meaning to the fastboot. If you want to boot to recovery, you need to select this option in the fastboot menu. I don't remember if you can use a fastboot command for that, and I can't turn off my phone to check.
On the ze500kl, when phone off, press vol- and power to enter recovery.
some progress
Thanks for the info. I did already try to wrok with the vol- button but it just keeps showing the ASUS and android logos and doesn't start twrp. I've succeeded to install the system thanks to the following site: (I c'an't post it cuz I'm not here long enough) however now I'm again not getting into twrp.

If you haven't unlocked your bootloader then you can't flash TWRP. You need to unlock bootloader. I have the 551ML so can't help here. Try the search function and read...
Try to erase your cache partition in fastboot with the command "fastboot erase cache", this might get you booting back into Android but since you've been playing around without doing the necessary reading, no guarantees...
To get to recovery, stock or custom, you must go through fastboot or bootloader mode. You need to use the volume key until it says recovery then hit power key. It will reboot the phone and most probably show you a droid on its back with "Error" above it (if it's still stock). Hold down power and press volume up to enter recovery.

I did qutite some experimenting today. What I'm currently ended up with is:
1) I can boot into the system.
2) I can't boot into the recovery of the Phone
3) I can boot the StockRecovery via fastboot however I can't boot TWRP by any procedure (Although I was able to do so during my experimenting. I don't understand why it sometimes works and sometimes doesn't)
4) My Phone is Rooted (at least it says so)
5) I have run the Unlock.Zip via TWRP when I had TWRP flashed however now I'm again at a point where I can't start TWRP at all.
I find this very confusing and I can't see any pattern to it. For now I'm OK with having a more or less functional phone but I'd like it to be more reliable and predictable in behaviour.
First of all you can't boot directly to recovery the way you are thinking. Booting into fastboot (actually called the bootloader) then selecting recovery is the normal way. You can't have 2 recoveries on your phone. So you probably did the tethered version of TWRP the first time. I don't have the link handy but you need to get the official TWRP and use fastboot to install.

You HAVEN'T UNLOCKED YOUR BOOTLOADER...
No recovery or custom rom will flash successfully... It will say it will, but you will either go into bootloop or just get stuck at ASUS logo...
Nothing will stick until the bootloader is unlocked, if you use tethered TWRP and flash a custom rom you will softbrick your phone until you flash a stock rom back on.
If you go ahead and flash TWRP onto your phone using fastboot then you will have NO recovery on your phone.
You have been warned...

Well I disagree and I think you are wrong . I strongly assume that I have TWRP installed as I'm able to boot into it without having the phone connected to the computer.
Consequently I HAVE unlocked my bootloader and I DO HAVE a recovery on my phone. And of course I'm not able to install a custom rom seing that there aren't any for my model yet.
I think however that I've (for now) [SOLVED] my problem and we're drifting away from the original topic. Thanks for your quick help :highfive:

can anyone help me? phone is stuck!

okay so i tried to flash a cypher OS rom on my sultanxda CM13 and my phone is currently not going into recovery so basically i am stuck in fastbood mode . my device state is unlocked and when i restart or try to go into recovery the phone just turns off and does nothing. the only way i can actually turn the phone on is by holding volume up + power + home (hard reset tactic)
can anyone help me?
so where do i go from here? i tried the toolkit unlocked and re-locked the bootloader, tried to flash stock recovery img, tried to flashing twrp, nothing works guys.
flash Original Rom
Make sure you're using latest modified recovery (28) by eng.stk.
From your description the phone most probably doesn't actually turn off, it just displays black screen (common issue caused by TWRP incompatibility).

You re-locked the bootloader while you were still on a custom ROM and/or recovery?

Recovery issue flashed but unbootable

Hi fellow G4 owners I have ran into quite a bothersome and weird issue after flashing a recent nightly of CM 13.1 on my g4 , I realized I couldn't boot into my twrp anymore , it seems to boot in what I think is the phone's factory recovery only displaying a few lines of text that are all related to the my bootloader's unlocked status .... Ive tried reflashing the recovery many time through flashify and adb , it doesn't change anything ....
Hoping anyone has already had that problem and could help. Cheers

Try
fastboot boot twrp.img
If you see twrp push the twrp image to your device and choose image at the bottom and flash twrp to recovery
Btw Download and use the latest twrp

Will try this and report !
Sadly it boots to the screen I was talking about in my previous post which actually happens to be fastboot not factory recovery my bad.
I did some flashing , apparently when trying to flash the latest recovery the flashing goes well but then I get an error saying there is a dtb error, I am unable to even boot it through fastboot.
I managed to flash twrp's 2.8.7.0 version but again if rebooting to recovery through adb command it takes me to the same fastboot screen however I am able to boot to this version of the recovery via fastboot commands and that's the only way I can actually reach a recovery .....
Hoping that helps in any way for other peeps in the same situation , I'm gonna try to flash a more recent rom will report once done !

Oh How do you try to get into recovery??? Which key combo?
Sent from my LG-H815 using XDA Labs
The volume key power button combo strangely never worked on my G4 I use either the advanced reboot on the phone or through ADB.
I just flashed the lasted cm 14.1 nightly after flashing an older twrp and booting into it , with that version I can boot into twrp with no problem but after flashing the latest twrp the problem reappeared .... This is so weird :/

The only valid and always working and supported way on getting with a key combo into twrp is using the factory reset screen.
Any other key combo like vol up + power depends on the kernel of the ROM! So it may work or not. Factory reset will work always.
for this you have to ensure that you have the latest twrp version really installed(!) because if twrp sits in recovery it will ignore the factory reset command when going through it.
Edit:
Check the faq in the official twrp thread for a howto.

[HELP] Mate SE in TWRP bootloop after installing openkirin lineageOS beta 4

Mate SE, installed TWRP 3.2.1-0 Pretorian80 Edition then installed openKirin lineageOS beta 4. Went to do a factory reset and now TWRP starts on startup but does not get past the loading page. Tried rebooting into bootloader, using the button combo or adb reboot bootloader only brings TWRP back up with the same issue. Any ideas?
From what I understand, you need to flash lineage via fastboot. Did you do that??

Yeah I launched the bootloader and used fastboot to flash it. The flash went through fine, then it rebooted and asked if I wanted to factory reset the device and I selected yes. Now it won't shut off, it only reboots into TWRP's loading page and sits there.
I should mention I have access to some ADB commands now but rebooting into bootloader won't work.
EDIT: got it working, just had to time rebooting it and plugging it in and holding vol- and power correctly, took me 30 or so tries, fml

Directly from OpenKirin's install guide:
"TWRP and other custom recoveries are not supported! Please ensure you have your device’s stock recovery installed. If you install the ROM with a custom recovery, we cannot assist you with any issues which may arise."

Yeah....I skipped over the sentence saying "please ensure you have your device's stock recovery installed" and thought installing it via fastboot without using TWRP it would be fine. It was not. IMO they should make the warning more dire.
All fixed and working now, thanks for your input.
How did you get it fixed?
