this particular g1 will boot to recovery, but doesn't flash the DREAM.NBH that is on the sdcard. it gets to the screen where you should be able to press POWER to flash the DREA.NBH, but nothign happens afterwards. I would assume it's not a hardware issue since the device powers on just fine with the power button.
at this point the phone becomes unresponsive to power+menu+call or any combination of keys.
$ adb devices - doesn't show a device connected at all, but it does for my other G1, and the Nexus, so I'll assume it's working correctly.
i'd like to flash either stock r29 with either adb, fastboot-mac, or whatever i need to.
any ideas ?

Hey everyone,
A couple months ago, my phone shut down and stopped working, it only did the 7 vibratios thing without responding any further, but today I tried plugging it to the charger and it booted into the HBoot. Now the problem is, the volume buttons are broken and I can't navigate the Hboot menu to reset it/flash it/whatever.
My question is: is there any way I could possibly get into recovery or basically do anything to flash it again/reset it without needing the volume buttons and only using the computer?
(I tried using adb prompts like adb reboot recovery but it says the device is not detected, however, it shows Hboot USB plug on the phone)
Tl;Dr: I need to navigate the hboot without the volume buttons.
If you boot normally does it take you to the splash screen? You can try it from there.
adb reboot recovery
Try adb devices as well.

I don't think you can use adb commands from hboot.
If you plug the phone in to the PC while in hboot then press the power button on fastboot (i think it is the first option so no need for volume keys) it should say fastboot USB. You can flash an ruu in this mode.
Download an ruu.exe and run it on the PC. If everything is well with the hardware it will flash a rom and automatically boot into the new rom. You will need to root again and flash custom recovery after if you want to.

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.
Hi
The Volume Down button is jammed (the phone fell and landed on its edge slightly crushing the frame where the volume down is). Curiously the Volume Up button still increased the volume.
After turning the phone off the problem came when turning on the phone as it now only boots into the bootloader as a result of the jammed Volume Down button.
Once in bootloader mode, the volume up/down buttons do not change the reboot options - it appears the stuck Volume Down button is causing this.
The way to fix this is to take the phone apart (as per the Youtube clips) and physically straighten the frame.
This is no easy task, so the question: is there a way around this so that the phone can boot?
It's rooted and fastboot commands work. (I installed TWRP but can only boot to recovery with adb).
Any help will be appreciated. Thank you.
fastboot reboot system?

No, the device is reading the hardware correctly and booting to bootloader. The only way to fix this is to fix your device.

He said he could still issue fastboot commands. If the device is OFF and he has to press the POWER button to turn it on, it is reading the VOL DOWN as being pressed as well. If he issues the reboot command in Fastboot, it should boot into system because he won't need to press the POWER button and VOL DOWN (being pressed by the bent frame) at the same time, right?
OP also said he could get to recovery from ADB, but I think he meant Fastboot because ADB is only available when you are booted to Android.
Clarification
"I installed TWRP but can only boot to recovery with adb" is unclear.
I was meaning that one can only boot directly to recovery using adb. In fastboot, one can't get to recovery.
At the moment adb can't be used - only fastboot.
When I issue the fastboot reboot command, it just returns to the bootloader. I was hoping it would bypass the Volume Down state, but sadly no.
Thanks for your input though - I knew it was a longshot.
By the way, the phone wasn't dropped, but came out of my pocket going up some stairs - the bigger size makes it not as stable!
A bit late to reply, but for the sake of the next guy that comes looking, the command you were looking for is:
Code:
fastboot continue
This should tell the bootloader to boot into system.
You are still right about not being able to boot into recovery from bootloader (that's the headache I am currently having)
Any way of disabling the volume key altogether without doing anything physical to the phone?
I tried editing Generic.kl from /system/usr/keylayout/, but that only makes a difference when the phone is booted, not before that. Any way to disable the key before the phone has booted?
Cuz this is my mum's phone and she will have no idea what "fastboot" is
Hi all,
I have a particularly tricky case here. A OnePlus 3T with a broken screen (its black, can't tell if its registering taps) which I need to recovery data (photos) from. Normally I'd just use ADB but of course usb-debugging isn't enabled. I've tried rebooting into recovery... hold the power button and vol-down until the phone vibrates, keep holding for a few seconds. Then wait. Then vol down twice and power again to hopefully select English but the when I try
Code:
adb devices
nothing comes up on the list.
I'm wondering if anyone has any ideas how I can recover data/photos from this device.
One again the facts are:
-OnePlus 3T
-screen is broken, black, doesn't display anything
-usb-debugging is NOT enabled
-i can see the device in fastboot mode (boot w/ vol-up+power)
Thanks!
Maybe try a mouse with OTG. Would be horribly difficult i guess. But can probably work.
Also with any recovery, it would require your pin to enter the recovery (for decrypting the partitions); so that's a no go.
All you can try is to just boot the phone normally and try any input with an external mouse with OTG. Bring it to a point where the phone is powered on and unlocked so that you can copy data off the flash storage in MTP mode.
Ps: why don't you try to normally boot the phone and use fingerprint unlock?
did you trying with this link?

Using this tutorial in this case would make no sense, since the damage is physical and this way you're going to lose all the data currently stored on the phone.

if you have no usb-debugging and cannot see screen you are out of luck. same thing happen to me. the only thing that worked was I had twrp recovery and was able to boot into it. Recovery by default is in mtp so you will be able to see all your folders and transfer pics or backup files. last resort was to send it to oneplus repair which will cost about 100 bucks and you will get your phone back within 7 days remember to tell them to not reset phone because they will if you dont. good luck
You can also recover the data very easy through data recovery softwares. No usb-debugging and cannot see screen you are out of luck. I also have to face same problem the only thing that worked was I had twrp recovery and was able to boot into it.
You can try to flash TWRP in fastboot, then reboot recovery via fastboot command. MTP would work unless a pin is required in TWRP.
I can feel the situation,the phone doesn't work properly.
Hi,
I'm not very experienced with those root things and followed a tutorial to do so.
I unlocked the bootloader, had TWRP installed and root. This worked. Now I wanted to remove Root and TWRP and go back to the original state. I couldn't find the stock recovery file, so I installed the P996A04V1.3.0B13_MR2_sd_ssl.zip via TWRP from the SD Card. Till here it worked. I could enter the stock recover and boot the phone.
Then Android wanted to install a security update. I allowed it and this is where the problem started.
The install process stood still on 25% for minutes. I thought it stuck and pressed and hold the power button to reboot that I can wipe the memory. But nothing happened. But the installation Process continued suddenly. I had the feeling that this power key worked like a skip key. So maybe it didn't install a file where it was stuck.
After the installation reached 100% the screen switched to black and nothing worked anymore. I couldn't restart the phone or anything but I think the phone was doing something cause it consumed electricity. When I checked the phone hours later I noticed it was empty.
I can reach the unlocked bootloader now, but none of the selections works. Doing nothing to boot or select Recovery lead to black screen and stuck. Then I have to wait until the battery is empty again. Fastboot, Power Off just restart the phone and I end in the Bootmenu again. I can't even fully charge the phone. As soon as it has enough power to start the Bootmenu appears. So I don't see the display of the charging process.
I don't understand how this could happen. I tried different key combinations when the phone had enough electricty to start. The phone always restarts and end in the bootmenu. Only when I press all three keys it's standing still on the ZTE Logo screen but as soon as I release the keys I end again in the bootmenu.
How can I force another Update?
regards
Let' start with the basic questions:
Do you have proper backup of your data?
Which Android Version did your Axon had before it went unusable?
You could try to reflash TWRP.
Boot your phone into bootmode.
Download a proper TWRP Image on your PC (https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547)
Open a cmd shell (press the windows key and type 'cmd' -> press enter)
Navigate to the folder where the TWRP Image is stored ('
Code:
cd C:\Users\[I]YOUR_USER_NAME[/I]\Downloads\
')
Type: '
HTML:
fastboot flash recovery [I]TWRP_IMG_NAME.img[/I]
'
Afterwards you could try to reboot into recovery mode.
I don't have a backup. But there isn't something imortant on the phone that I want to keep. I can do a full reset and reinstall, too.
Android must have been the latest offical availabe what's in the file. Was it Android 8? V1.3.0B13
The fastboot mode doesn't work. The screen turns black and the LED blinks red but only for a moment. Then the phone restarts and I'm in the bootmenu again. Windows doesn't recognize it as device.
Is there a way to force it to do an update from my SDCard without it needed to be connected to a PC?

I don't know of any.
But you could boot into EDL Mode (Press and hold Both Volume button and then press the power button) and flash a Stock EDL rom from the Download Center i have linkd before.
It's not visible for the PC. The only thing I see is the charging screen when its total empty and you can't even boot as. As soon as it has enough power to switch to the normal screen the bootloader appears and when I do nothing the screen turns black and nothing happens. I don't even know if it is charging. The LED is off.
Follow this guide to unbrick it and then use MiFlash and flash an EDL ROM
