Run vivid with no battery? - HTC Vivid, Raider, Velocity

Is this possible? I can get it to boot into hboot, then remove the batt. With charger plugged in and it still functions. When I try to boot from recovery from hboot, it switches to HTC screen then shuts off. Can't be a hardware issue since it boots to hboot with no batt. Would be cool feature if I could boot with no batt.

Going into the bootloader doesnt require that much power... Hence why it works with no battery. but once you start going into recovery it starts loading more and more stuff requiring more battery and having no battery and only being pluged in isnt enough juice for it

There is a hack I did with my droid 2 where you get a usb cord and put the wires on the terminals of the phone to give it power and it will boot up I forget what it was but I think I bricked it with no battery power and had to do that to boot to bootloader and flash the file to return it to stock I would Google that and try it out

I'm gonna use this phone as a media server when I get my new one. Didn't want to leave in the battery plugged in all the time. I check it out. And the battery provides the less than the charger. If you use a phone while charging, it charges. Which means charger is outputing more than batt.

Power button not working how to start my mobile

I am using Motorola Milestone, with 2 months warranty left.
Power button is not working and it drained off the battery last night. Now I am unable to start it. I am running a custom ROM. Without restoring to stock I will not be able to offer it for warranty.
It currently power off condition, how to start it without using power button?

Try removing the battery and plugging it into the wall charger to see if you can boot it up that way, you might be able to boot up enough to reinsert the battery and have it charge.

I booted it connecting to PC
In case somebody else has the problem:
I connected it to the computer without the battery and then inserted the battery...
I know that the OG always started when I plugged it in to the wall power adapter. I didn't have to take the battery out to force-boot it that way. Guessing the Milestone would be the same. Glad you got it working

[Q] Can't Boot Phone

So I've been running HoliRaider v1 and it's been working beautifully however last night my phone died, and when it dies it boots into recovery. This is usually fine however the phone will not charge in recovery but instantly boots into it if i plug it in. Basically, it's stuck there because it only charges (as shown by the orange light indicator) for a second before entering recovery. Then, it just stays there. I'm not sure if I should even restore at this point, as that wouldn't exactly work with 0 battery. If anyone has any idea what to do please let me know.
Looks like you either need to charge the battery using a stock phone from either a friend or go to the att store and see if they will let you charge your battery on their floor unit for a few

at this point getting the battery charged is priority. this is probably your best bet without having to buy some kind of charger or new battery

I had this happen when I first got the phone. Should you eventually get it to boot (I did after taking out the battery, putting it back in, and then trying to turn it on while plugging it in, it took many attempts), let it charge to 100%, then flash thecubed's ClockworkMod which supports chargemode when powered off. You should be fine after that.
you can flash the recovery in fastboot if the phone stays on long enough.

Personally I wouldn't flash anything with a battery that may conk-out mid-write.

Nope - you'll need to charge it externally, then you need to get new recovery. CWM doesn't support off mode charging, so if your battery dies, you have to charge it out of the phone. Go to ATT store and ask them if they can charge it for you for a while
Just a question what is off mode charging?

Ok guys I think I got it.
What I did was
Take out the battery
Put the batter back in
Plug in the charger
When the light come on hold down Vol down and power button
When phone boots to bootlader choose recovery
you will get white HTC creen, leave phone plugged in for a while 30 mins or so
then while leaving charger plugged in attempt to power phone pn
phone should boot regularly
Finally.... don't let phone battery run down or get external charger or change to twrp as one person suggested.
I'm just glad that I was able to get my phone booted, as I live outside the US can't go to an ATT store and HTC phones aren't the most popular here.
I'm wondering if I should order a battery from Amazon just in case :silly:

[Q] HTC Vivid won't charge or turn on

As the title says, my HTC Vivid won't turn on, charge or anything. The orange light that says it's charging doesn't turn on, buttons don't vibrate or anything. It shouldn't be bricked because I haven't done anything to brick it. I was using Xbox Smartglass on it, I locked the phone and went back to my game, about 15 minutes later I tried to unlock it and it did nothing. The battery shouldn't have been dead because I charged it the night before. Any suggestions or help please?

LOL The reason I got a Vivid is because he gave it to me. Sadly, I was hoping there would be a technical solution instead of trying a new battery. I've got one ordered though. :/
Some have bad batteries.
Mine started doing the same thing. For a while I thought the battery life on Vivid was horrible compared to the Aria I had at the time. Then it progressed and one day finally quit completely and would not take a charge from any charger I had. So, being a techhead I decided to probe the battery with a multimeter and it showed very little voltage, so low I guess the charger wouldn't even recognize or try to charge it.
So what I did was take a battery charger I had for a walkie talkie radio and touched the leads to the battery for 3-5 seconds or so, put battery back in phone and it would then charge. I did this a few times until I could get to ATT store and the guy ordered a new one through warranty. Haven't had a problem with the Vivid since.
Same Problem
Last night I pulled my battery at 21% after shutting the phone off to clear the memory. I put the battery back in and put it on the charger, I tried to turn the phone on and nothing. It is not showing that it is charging. I have four batteries for this phone and none of them will turn on the phone. I am at a loss here. The phone was working fine until i shut it down and removed the battery. Any ideas on what is causing this or any way to force it to turn on.

That sounds like a royal pain.
Could it be the changer or its USB cable? Work some contact cleaner into the power button?
I'm having this same issue. I'm not sure if it's the battery, since the phone boots to bootloader just fine. But the battery won't charge when the phone is off (red light comes on for a second, then quits) and I can't get past the HTC screen booting to ROM or recovery. Where is a good place to buy a battery?
Even if the power button was bad the phone should still charge a battery. I have a charger that will charge the batteries without the phone so I know the batteries are charged. I have several different chargers and none of them will show the phone charging. I even tried connecting it to my computer. The phone is dead, I guess I am going to have to crack it open and see if anything has come loose inside. I really like this phone and am going to hate loosing it. I paid a lot for this phone. That shinny penny I paid to get this phone was my favorite.
Have you tried plugging the phone USB into a desktop and using that to try rebooting the phone into bootloader or recovery?
Hasoon2000's Vivid All-In-One Toolkit in the dev section can do that pretty simply. i used an earlier version of that to unlock the phone a year and a half ago.
i don't remember if the phone has to have debugging turned on for the desktop to feed it commands.
Even if this works i dunno whatall it'll prove.
i like this phone too a lot, and am sorry yours seem to be having hardware problems.

That sounds like you lost your boot image... try flashing a new one that you know works... and if it won't charge with power off... sounds like you have CWM installed... switch to twrp...

The phone does not turn on at all so getting to the bootloader is impossible. It does nothing. Does not even charge a battery. .

That's the definition of a bricked phone, was what i meant. No screen, no led, no button function, no sign of life, and from no explicable cause.
Android phones don't have real on-off switches that directly disconnects the phone from power. Its failure to manifest signs of life doesn't absolutely indicate irreversible hardware failure. There's a bit of a chance it's firmware.
Aside from the power button, Android phones can be controlled thru the USB port.
I took your advise and plugged the phone into the computer and left it over night. This morning I rebooted the computer and the phone screen lit up. I got all excited and tried to use adb to reboot into bootloader, Of course the phone was not found. I took the phone off the cord and the screen shut off. I pushed the power button and the screen lit up. Let go of the power button and the screen goes off. I tried another usb cord and now the screen no longer lites up. Maybe there is hope for this phone.
If the screen lights up like that... there is power to it...
Sounds like you have dirt in your power button... or the button isn't making contact...
Time to disassemble and check the power button...

Yeah, that part where the phone was seen by the desktop, and then not, can have something to do with the Windows drivers. Most of the folks on these forums know what's with this stuff better than me; i usually have to tell windows to stop the hardware, disconnect and reconnect the phone USB and start the connection up again, every time before i do one set of commands, like put the phone into bootloader and download a kernel image into it.
There's a Vivid unbricking project over in the dev subforum, you must've seen that. Whether or not you get your phone working again, i hope it'll be a productive journey for you.
i was perfectly happy just messing with apps until i bricked my tablet; that got me into all this device unlocking and rom burning and fun stuff. It's too bad the Vivid isn't simpler to hack.
my phone cant boot to desktop after i flash the kanel
my phone cant boot to desktop after i flash the kanel please can you help me
9 times out of 10, if the phone will not turn on at all it is the battery. For some reason, the Vivid will occasionally stop seeing the battery. I have fixed this on mine when that happened by using an external charger. That worked because my battery was actually OK, the Vivid just wouldn't charge it or even see it. Once it was charged it was fine. If your battery really is dead (sounds like it might be the case), get a new battery. There is a 2000 mHr battery on Amazon that is not too much worse than the original (when new).
I had the same issue once, it turns out that I fixed it using a external charger

Power up when charging

I am planning on repurposing my retired Vivid as a media source for my car. I intend to have music stored on the Vivid (or a USB via OTG with power) and expect it will be plugged into the charger at all times. Since the charger outlet in the car is only "hot" when the car is on, I would like to have the Vivid on only when charging power is provided. I have already figured out how to power it off when charging power is removed (Tasker). What I haven't figured out yet is how to power it back on when charging power is started.
I have a rooted Vivid, with HBOOT 1.85.0025. It is still S-on if that matters. With the device powered off, I get a blank screen and charging LED when connected. I do not get the animated charging battery icon that was stock on the unrooted Vivid.
How do I get it to boot up when power is connected?
Unfortunately, I do not know of a way to have the phone boot up when it is charging. I think you would have to replace the charging while power off animation with some sorry of script that boots the phone. This would likely require s-off, but while doing s-off is pretty easy, the script would be another beast.
