OTG USB in recovery mode (TWRP) - Nexus 7 Q&A, Help & Troubleshooting

Does anyone know if a mouse using an otg cable will work in multiboot TWRP recovery mode (also the multirom screen, but thats not as important right now) or if the screen rotates. I cracked my screen (digitizer cracked, LCD is fine) an am looking for a way to flash new roms but not dont want to restart my tab because im afraid i wont be able to get out of recovery mode (bottom half of screen is unresponsive). im running m-kernel 32a with multiboot. I cant even remember if that recovery supports hardware button presses.

Amon recovery help

so I've rooted a couple of eris' so far and its all turned out fine but on my brothers (his came with 2.1) i tried and everything worked but in recovery it doesnt respond to anything except the action button to select reboot now. Did i possibly do something wrong? the trackball just doesnt scroll, i guess thats the only problem

I don't think that has much to do with the Amon_RA recovery, although I sort of remember other people reporting a similar phenomena.
If the problem is repeatable, and the trackball works when you are in the regular Eris OS, then I would just fully charge your battery and re-flash the Amon_RA (v1.6.2) recovery image (of course, after making sure of matching md5sum signature).
I had the problem you describe exactly once - but it went away by powering down the phone and rebooting (back into recovery), so I didn't really associate it with the Amon_RA recovery; just assumed it was a momentary problem with the trackball.
Or maybe if the problem persists, maybe try altering how you get into recovery? (e.g. instead of going in directly from power-off state by Vol-Up+End, go into HBOOT first and then Recovery from there?)

I've tried toing into recovery both ways and reflashing still no luck...
Same issue
I am wondering if whoever made the recovery could redirect the function of the track ball scrolling up and down to the vol up and vol down keys?
well those keys are supposed to also do the up and down function but nothing responds except the action button
i'm having the same problem.. had this eris rooted for months now.. switch between roms plenty of times but today when i went into recovery.. no scrolling at all.
Even rooted with P000 img again and pushed the recovery img again but still the same troubles.
I guess i'll try with a fully charged battery.
If that doesn't work for you try clockwork recovery. My trackball works in every direction but down, so I couldn't use amon's recovery. In clockwork you use the volume up/down to navigate.
Sent from my Eris using XDA App
I would try all other fixes or options before flashing Clockworks Recovery...it has been known to cause an Eris to brick. Which is why ROM manager is not used by us.
while letting the batt charge..
i went ahead and reformatted the sd card incase that was an issue.. no dice.. still no trackball / vol up / vol down movement.
any adb codes to wipe and install zip from flash ?
still waiting to try full battery (at about 60% )
your trackballs are broken you need to return your devices for refurbs
or wiggle your usb cable around inside of the port while in recovery and playing with the wheel to find out where yours works at
Second option works.. wiggling the usb cable at the point where it connects into the phone while moving the trackball does the trick.... i don't understand why though.
Trackball works fine scrolling up and down in notepad program and usb cable charges phone/connect to computer fine
But it does work so thanks for the suggestion

[Q] OTG USB in Recovery Mode (TWRP)

Does anyone know if a mouse using an otg cable will work in multiboot TWRP recovery mode (also the multirom screen, but thats not as important right now) or if the screen rotates. Looking at the OP i noticed a "tablet look". Is this on the nexus 7? I cracked my screen (digitizer cracked, LCD is fine) an am looking for a way to flash new roms but not dont want to restart my tab because im afraid i wont be able to get out of recovery mode if i boot into it.besides the thirty second power button hold (bottom half of screen is unresponsive and i cant access the onscreen buttons to reboot from recovery or to go to the advance menu which are located at the bottom). im running m-kernel 32a with multiboot. I cant even remember if that recovery supports hardware button presses.

A quick 'google' has answered the question. Anyway, if you cannot use the mouse in recovery for whatever reason (and haven't flashed or done anything, and its unlikely you would since the mouse isn't working) then you can just open up the back of the nexus 7 and take out the battery? Or try holding down power and vol down to get to fastboot (and use volume/power) to reboot back to normal.
Good luck
Mmmm. That is a bit of a dilemma.
I was going to suggest - IF your bootloader is unlocked, you would (in principle) have the option to "soft-boot" different recoveries (even a plain-ole normal OS boot image for that matter) via the command line (or perhaps with a toolkit - I have no knowledge of them).
fastboot boot boot-or-recovery-image-file.img
which would allow you to use just the volume rocker and power button on the alternate recovery. Obviously, you need to have fastboot communications set up (drivers for your PC) as a pre-requisite,
(Nothing about that suggests you need to flash a replacement recovery to the device - soft boot what you need for a single session at a time.). That gives you the option to play around with mouse experiments at your leisure.
In order to do that, though you certainly would need to quit your current boot. Two finger salute for that? Or perhaps doing the reboot through ADB failing the former?
Just an idea anyway. Since you are using multiboot, I might not be aware of kinks between a different TWRP version and getting multiboot kernels to come up - but you said in the OP that you were interested in replacing ROMs, not saving the one that that is there....
cheers

I think the catalog is talking about stick mounts and USB storage. I couldnt find anything on using a mouse in recovery. even youtubed it, only one person shows that a keyboard works on CWM recovery. nothing about TWRP.

[Q] flashing custom ROM with broken digitizer

I want to put a custom ROM on my Nexus 4 (currently unrooted, completely stock Android 5.1.1). Unfortunately, the device has a broken digitizer and about an inch of the screen is irresponsive to touch all the way from left to right (it's pretty much right at the top). Will I ever NEED to press the screen there, during the whole process of unlocking bootloader, putting custom recovery, using said recovery, flashing the ROM, and so on? For example, can you use volume up / volume down to navigate through Clockworkmod, etc?
You don't need touch screen to unlock bootloader, it's all done through volume buttons. As for recovery, use ClockworkMod Recovery (CWM) which uses volume rocker navigation.

Screen black (broken) - How to recovery data (no usb-debug)

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.

Kernel Panic

Can anyone please help with this serious problem I'm having. Right now I have a paper weight because I flashed the newest magisk beta 14.5 and it gave me a kernel panic screen. I can't get into recovery no more using the hardware volume button because it broke and the part that connects to mother board is shot. Is there a way to do it through ADB while in kernel panic? But also for some strange reason my girlfriend's lgv20 and mine won't show up on the computer, but the PC is saying a LG device is connected but it won't show up on the file explorer. My son's lg Stylo does just fine I tried different cables too. What's crazy is they both used to pop up on the screen. I don't know if it's because we don't have the original lg Data cable or what. My son's cable is cheap and works for his phone to show up on the screen.

I was running magisk 14.5 just fine so I'm not sure what caused the kernel panick. If the volume key is broken that makes getting into recovery a pain. You can always boot into fastboot manually (volume down And insert usb cable) and use fastboot commands to reboot to twrp but if the the volume key is broken that's an issue. adb I believe won't work until you are booted into the os or recovery. Worst case go into download mode (volume up and insert cable) and flash a valid kdz. That's a 100% guarantee to fix. But once again if volume keys are broken you might be in a pickle

I kind of figured I would be S.O.O.L without working volume buttons, thanks for the info

If you can't pull your battery then just let your battery run out. Once you charge up again it'll boot regularly.
