Yotaphone 2 - another bricked phone after update

Hi guys,
My Yotaphone 2 is currently stuck in a boot loop (shows android logo, then black screen, repeat) after a software update. I can get to the 'Downloading...' screen via power + vol. key and so have tried adb/fastboot as suggested in other similar threads. ADB can't see the device, which I guess is probably normal since it isn't booted up, but fastboot seemingly can. I've tried flashing the TWRP recovery which seems to go through fine on the PC end but doesn't seem to do anything at all on the phone itself. Calling a fastboot reboot gets the phone back to the boot loop and power + vol. goes back to the 'Downloading...' screen.
I've also tried using the Yotaphone flashing tool to flash a full android image - this also looked like everything was operating OK on the PC end but didn't seem to change anything on the phone once the process was complete.
Is there anything I'm missing or anything else I can try? Any help/ideas much appreciated!
Cheers.

Do you have any idea what caused the bootloop? (maybe installing xposed or something?)
When you keep vol-up pressed at (not after) the moment the phone vibrates during power on, you will end up in TWRP recovery. There you can at least wipe->factory reset. Don't do this if you have stuff on your phone you'd like to keep though. (you can try to rescue/backup those by trying "adb pull <path_to_file>" when the phone is booted into TWRP)

It was caused by doing an OS update (wasn't rooted or modified), I've only since tried installing the TWRP recovery and using fastboot to flash an official image to fix the looping. Flashing TWRP appears to work according to flashboot but holding the volume up key at the vibrate on power on doesn't do anything sadly.

Maybe I should rephrase: the vol-up should already be pressed once the vibrate starts. For a timing-insensitive, fool-proof (no pun intended) way you can enable bootloader (like you did before: you get the Downloading... screen). Then keep vol-up and power pressed together, after 15 seconds the device reboots hard, keep both keys pressed until you see TWRP 'curtain' screen, then release.
Did you try to use the YotaFlasher Windows application to reinstall an official ROM and restore factory defaults? You can get it from here, also download a ROM for your region here.

Recovery in Chinese

Hi all,
Got this phone last week. It's been really laggy and basically unusable, it even lags when receiving calls and I miss half of them from being unable to answer. I was advised to wipe the cache partition, but the recovery menu is in Chinese. I got in touch with Motorola support who first tried to get me to delete all my data in the Chinese recovery menu, then gave me instructions to wipe the partition in English which I can't follow because the menu is in Chinese, and then said they couldn't help further. I can't find any other examples of Motorola phones with a Chinese recovery menu online.
Really not sure what to do!
Thanks for reading.

When I pressed power+volume down, phone booted into some Chinese screen, but it was not recovery, it was I think a testing menu. You might have pressed the same buttons. To boot to recovery, press power+volume up, this will launch a menu, keep pressing volume up to select recovery, then press volume down to launch recovery, after launching recovery you'll see no command screen, there you should hold power button and press volume up, this will launch recovery. Hope it helps.

That worked, thank you! Motorola were less than useless. Much appreciated.

In case it helps anyone, I fixed the lagging today by installing a new version of google play services, which I found by googling. Made everything better.

Please confirm which version of Google Play services you installed as I have the same problem.

This wont work for me it will just restart the phone back to where you can choice fastboot, recovery and normal.. ****ing annoying.... Got the bot with no command text under and press power button and volum up frustrating. Even worse when someone els got it to work so it should be working.

You have to hold Power button and tap volume up. Don't press both buttons simultaneously, hold Power, while holding Power tap volume up. If it does not work, then a system update might have changed the process (though highly unlikely I think).

Stock images for e3 Power are available somewhere in the forum. Try flashing stock images. By the way there is no need to format userdata while flashing recovery.

Okay i managed to figure it out spent 5 houres or so had to use SP_Flash_TooL and some USB VCOM drivers for phone this can only be used on MTK chips.

trust me i just saw this post every google search is saying stuff about pressing volume down like it works XDA developers are life and life savers been using this since like 8 years ago and it still going strong had to leave my first comment

My huawei y511-u30 mobile is showing chineese in recovery mode and its not working also. As i want to flash my rom unable to get device detected by pc also

Power off While Stuck on Bootloop

Hello guys, been a while, but I got myself into trouble. For a while I had rooted the phone but one time I rebooted and it supposedly no longer had root. Today I got a notification that magisk updated, so I decided to try it. I booted into recovery and tried to flash. Nothing happened. I tried wiping davlik cache and tried again. What ended up happening instead was that the phone was unresponsive. I attempted to reboot, but instead I got stuck in a bootloop.
I realize the most effective way to get out of it is to flash the firmware via Odin, but since I didn't make a backup I want to avoid that if possible. The problem is that other than the soft reboot (power + volume down) I cannot power off the phone to access recovery mode! I've searched and searched, but have only found ways to soft reset, which doesn't help me access recovery mode.
Is there a way to power off the phone while stuck in a bootloop? Or, alternatively, is there a way to boot into recovery while in a bootloop?
It's so frustrating to not be able to something as simple as a battery pull since the phone is sealed. Is there a way to replicate that to be able to power it off?
Any help would be appreciated.

Hold the power button for 10 seconds.

Hold Vol down and power for soft reboot. As soon as the screen goes off to reboot quickly switch to recovery combo (bixby + up + power) it should boot to recovery

What if Vol down and power don't work, adb, fastboot and device manager don't see it, any other combinations tried too, wait for full discharge don't option. Help plz

Did you manage to get out of this?
Im really scared i bricked my phone now. Everything was working fine but after i did a normal reboot it suddenly would not start up.
Screen is black and the only way i can get a response from the phone is the soft restart (vol down + power).
I need to get into recovery somehow so i can restore my nandroid backup but vol up + bixby + power doesnt work (i assume the phone is on and frozen or something?)

I managed to fix my phone. After leaving it for 24 hours the battery was fully drained. After charging again i could boot to twrp and restore my nandroid backup.

Can't get into recovery to save my life!

Guys, I'm wanting to get into recovery mode to wipe my Dalvik cache but for the life of me I can't get to it. I'm doing up+power+home and I go to screen saying 'Downloading do not restart target'. I guess this is download mode. How do I turn this off?
For kicks I tried down+power+home and it asks me if I want to enter download mode. Also tried up+down+power+home but this just does a normal boot.
I know this is probably something really basic but I just can't get in. I did have KingRoot installed a while back. Could this have caused the problem? Any help is greatly GREATLY appreciated. Thanks!

Hold power and volume down, then press volume up when the OS warning screen appears = download mode.
Hold power and volume up = recovery.
Don't bother with the home button. You don't need it. Should the key combinations not work correctly, you may have bad buttons on the motherboard.

Thanks for the quick reply. I double-checked my volume buttons and they work as they should (up = louder; down = softer). I tried power + up and still get the download mode screen. I even tried adb to boot into recovery and it brings me to that same 'Downloading do not restart target' screen.

Prior to writing my post above I tested my S4 to make sure I was giving correct information. Both key sequences worked on my S4.
The only thing I can think of is that you have a hardware issue with your volume down button. To test, try pressing and holding power without touching a volume button. If you enter OS warning mode without pressing a volume button, then your volume down button is worn out and needs to be replaced.
My reasoning is this.
Button failures are the most common issue with the Galaxy S4.
You instantly enter download mode by pressing power and volume up while being unable to enter recovery at all. This means you're skipping a step in accessing download mode, which wouldn't happen if all the buttons were working correctly.

Maybe, but shouldn't my phone go into recovery when I send the command to enter recovery from adb? It just reboots and goes to downloading. My buttons work fine when using the phone when android is up so I'm doubting that it is a hardware issue.

It should, but something is interfering with that. I'd go back to stock using Odin, simply to ensure all parts of the firmware match. Then see if you can get into the stock recovery with the key combo. If you are able to, then you can restore TWRP and flash a custom ROM. Otherwise the device needs to be looked at.

Thanks for the reply. I'm running the stock os without root. All I really want to do is wipe Dalvik cache. Can I do that from adb?

Yep.

Can someone please help me unbrick my phone

I flashed an 8.0 rooted stock rom from lineage then tried to load my lineage nandroid backup and it was broken and i couldn't get back into twrp so i reverted with kdz and now im bootlooping and i get the "Erasing" screen every time i boot im using the vs995 by the way

Only idea I've come up with so far: try booting into recovery to maybe unstick it by using the volume keys? Same way as twrp, hold volume down, power til screen turns on, then tap power repeatedly (still holding volume down) until the factory reset menu appears, confirm the reset using the volume and power buttons.
Other than that trying to reflash the kdz I suppose ( that did appear to work correctly aside from the bootloops, no other errors?)
