Boot up when plugged in? - Sprint HTC EVO 4G LTE

Hello,
I am working on a research project in which I need this phone to run continuously. However once the phone loses charge, Someone has to press the power button to turn it back on. I need the phone to power on without any human interaction. After looking at other forum posts, I found that I needed to modify the phones system settings. However i do not know which file in the system folder needs to be modified. The only thing that runs when the phone is off is the charging light. What file runs this charging light when the phone is off? or Is there a different file that runs when the phone is off? or Is there another way to make my phone do this? My phone is an HTC Evo 4g, It is also rooted.
Any help is appreciated

Touch Pro abruptly stopped working; won't boot.

So here's a peculiar incident:
I have a CDMA TP with a stock ROM and a few basic apps I gathered from these forums and others. I've had it for less than a week.
Tonite, I went to check my text messages. Suddenly, the screen went black and the phone stopped responding. After pressing the power button and fiddling with the keys, I pulled out the stylus and did a soft reset. No response. Confused by this, I tried again, but still nothing. I removed the battery, and turned the phone back on. It froze at the "Touch Pro" screen with the rom/radio/etc info at the bottom. After repeating this a few times I decided to do a hard reset. So, I turn the device on and perform the hard reset. By this point the TP is only turning on SOME TIMES, and I have to take the battery out and put it back in often just to get it to start successfully. So, I finally get the device to boot up and it starts to configure WinMo. Suddenly, while configuring, it freezes. Now I try to turn it back on, and nothing happens.
Basically the device is stuck like this, shifting between not turning on at all and turning on but freezing at the "Touch Pro" screen.
So, my question is, what the heck is going on here? Has anyone else had this problem, or does this sound familiar to anyone? Any help would be greatly, greatly appreciated.
p.s. Yes, the battery is fully charged.

Time to take it in and get a new one.....
Same problem here phone started b not coming out of lock mode. Backlight is on but no display on screen (if i tilt the screen left and right i can see light coming from behind) did about 6 hard resets and still same problem. also power button works whenever it wants to. this phone sucks @ss, i want my mogul back. on a second note my replacement will be here on wednesday.
Touch Pro stock rom purchased back in nov when it came out
yeah, i've had the same problem, i found if i hit my phone on the back or side and then batter pull and hit the soft reset while off, not the power button to turn it back on, it comes back on with color on the screen not just blank black screen with backlight, this works mostly every time, but when it doesn't, i just hold the power button down and do battery pull and hit the power button and it works, its like its got a combo of things you have to do before it works.. weird
Boot Up
I have also had similar problems. I for some reason sometimes have to remove my SD card and boot up without it for some reason. Not all the time, but every once in a blue moon. Not too sure how that affects anything, but you may try that too.
well i started a thread here ***help*** because i kinda have the same problem.
i downloaded some cabs, nothing fancy but i had some problems with a theme i downloaded. when i went to deleted i couldnt..... to make a story short, i took it to the sprint store where they tried to do a master reset/ hard reset and it wont take it. it wont do a thing... they say some important files are missing...
the phone works but not the way it should... the time on the home screen wont show up. and some other small things...
dont know how this happened but i would like to know... im worried about new programs to the phone now. ( getting a new one)
still want to see if i can fix this one.

Have you tried re flashing the ROM?
it wasnt HTC's fault for your phone's not booting...thats what happens when u try to mess with the hardware too much and you dont know what your doing
Would you want to sell???
Reboot Brick HTC process
****DOn't take battery out after hard boot***
1.just watch videohttp://www.youtube.com/watch?v=sk56olMkCtU and do what they do but dont take battery out. LEAVE phone STUCK on BOOT screen. Nothign else will move or work but you want phone just like that.
2. connect usb cable to active sync. (this may not link up but leave usb connected anyhow) Do not delete phone profile.
3.use rom like Download MightyROM6_Herman.exe avail at: http://www.lilrico.com/Mighty/mightyromblog/?p=454
4 although active sync is still attatched but may not be connecting. It will connect thru usb anyway when you run the rom software. http://www.youtube.com/watch?v=fV2I2WAFkg4&NR=1
This worked and kept phone from cutting on and off. and restored ROM. don't know about original htc boot. but your phone will work under this rom for now and you can go from there.
hey thanks plain ole dumb, it works now.
man I thought it was over.
thanks again

[Q] Device Freezing / Dying?

Has anyone experienced their phone freezing/locking up? I'm not talking about lagging/freezing applications, but the whole phone actually locking up.
My phone seems to be freezing up about twice a week and has been for the last 3 weeks. Each time it has been when the device was in my pocket or on charge at night (and subsequently the alarm does not go off).
When the device is frozen like this, it has no indications of even having power.The power button will not turn the phone off, on, or wake the device. Plugging the phone into power doesn't even turn the orange/green charging lights on, nor play the tone for when power is connected.
I physically have to remove the battery for a few seconds from the phone and re-insert before the phone will start up. I have even performed a hard reset on this device.
Has anyone else experienced anything like this? I'm thinking that it might be a hardware fault, or at a really wild guess maybe the HTC Attentive App.
I'm having no problems with crashing or freezing!
I have actually found the device to be very stable, a lot nicer cleaner and stable than my previous device (Sony Ericsson Xperia X10).
Had exactly that problem a couple of times already. The only solution is to pull the battery out.
Still - better than an iPhone crash which requires you to plug it back into the PC before it will work again.
I had a similar situation:
I was making an international call (card service), when finished i heared the card IVR prompt if i need to make another call. I wanted to hang up but the screen was black adn dead. power button did not bring into life and i was keep on hearing the active call. had to take the battery out to kill this situation.
typically windows behaviour
Thought I had narrowed this down to the HTC attentive app, but alas the phone froze again this morning after hitting snooze 3 or 4 times. Oddly enough, the power button would turn the screen on and off, but the lock screen wouldn't show, nor could anything be moved or controlled on the screen (live tiles were still animated though). Battery pull again.
Yeah, typical windows behavior. No where near as bad as Windows Mobile which I came from though
I have the same issue. Can be in the middle of a call or anything. Had it reboot once while on charge too. Did you just remove the attentive app? Would it be worth trying a Hard Reset if that wipes the device. If so how easy is it to put your old Apps back on. Or do I need to write a list and search manually.
I did a hard reset and just didn't install the app again.
"When you buy or download apps from the Zune PC client, those apps are automatically redownloaded to the phone when you reset the device and login with your Windows Live ID again. When you download apps from the phone itself, you have to go to the Marketplace again to manually find and redownload the apps you want."

Auto turn on the phone when charging

Hi All. I have a problem with my ultra and maybe someone can help me solve it I want to install the phone to my car so I can use it as a sat nav and i cant find a way to make it turn on when charging. I rooted it and I couldn't find the playlpm or lpm file to edit it so i found somewhere a note to change the chargemon file but it gets stuck on the booting screen and i need to flash it now. Anyone knows maybe which file i need to change ?
PS. sorry for my english but its not my native language . Thanks for understanding
Settings, display, wake on plug
but I need to get it turned on from the point that its completely turned off.

Thought about doing this at one point but pretty sure it's a no-go. Instead, just buy a N7 for really cheap now. You can enter a terminal command that changes the resolution/usable portion of the screen to make the display the same size as the ZU or whatever size you want. This worked perfectly for me because my radio opening is 1.5 DIN.

Lollipop 5.1 bootloop....sort of?

Hello everyone,
I've been a reader for a while, purely out of interest. I've never really dabbled with customizing android. In that regard I am a noob... I recently acquired a Medion X6001 that I was planning to build into my car as informant/navigation. Phone root successful, developer options active, debugging and oem options active. Automate programmed to all the standards I was happy with., worked great. All that was left to do to was get the thing to boot on charge. The "fastboot oem off-mode-charge 0" command was unsuccessful so I resorted to trying to find the system file responsible for battery icon on charge with power off.
That's where I went wrong. This phone has two icons; first a battery with a bolt, then switches to another with blue fluid and battery percentage. I found the blue fluid battery icon - 'system/bin/kpoc_charger', unfortunately I needed the killswitch battery icon. So I made another guess and renamed - 'system/bin/lmkd'. This was the file directly before ...kpoc and my daft logic lead me to believe that that might have been the right file. Obviously, it wasn't.
So the problem? The phone won't boot. Not really... At first, it was entirely stuck in bootloop. So, the good sheep I am, I factory reset the phone through recovery. The phone still went into bootloop for a few minutes, but came out of it to an applet saying 'optimizing apps'. Took 10 minutes to optimize and then went through to another applet saying something along the lines of "system process not found, do you want to wait?". Behind this applet I could tantalizingly see the startup screen of a freshly reset android.... It gave the option to wait or push ok, neither of which were actually active to touch. If I held the power button it would give me the option to shutdown, reboot or screenshot, also none of which where actually active to touch.
So after more googling, I wiped the cache through recovery. Everything stayed the same; bootloops for a few minutes then applets. Only now everything is in Chinese kanji... which is why I can't reiterate verbatim what the applets originally said...
After around 12 hours of tirelessly searching the web I've tried everything I've found but every time I get through a door there's another one closed. I can't install twrp or clockwork, I can't flash the rom, the phone won't let me unlock the bootloader in fastboot. Went I type the command it asks if I want to unlock it: volume up yes, volume down no. But fails: "remote access denied"
Since the factory reset, I don't have access through adb anymore. If I let the phone boot I can see it connect to the computer, but only as mtp. The file is entirely empty. I have no access to usb debugging. And to remotely access that, I need to be able to unlock the bootloader.
I can't get around the blocks and everything that is advised to get around bootloops and flash through fastboot are seemingly impossible because I no longer have proper access. But I can't get into the phone to get access...
And to make matters worse, just now as I type this.... I can't get into fastboot anymore. I think the phone battery is dead, but apparently doesn't accept a charge. When I plug it in the battery symbol appears, the dark red led lights up indicating very low battery. Very shortly after that the led turns off, which is not how it was before I buggered everything. Battery icon stays on, but when I push the necessary buttons to get into recovery, everything goes blank and the phone does nothing. When released, battery icon comes back and red led for a few seconds. Repeat. Phone has been plugged in all night....
I'm nearly bald from pulling my hair out. I hope there's someone out there that can give me a hand. I have a hard time believing I bricked the phone just by changing a bin file name.
Thanks in advance!
fastboot
I have access to fastboot again. Plugged the phone into a different cable, is now charging. I can see the battery % through recovery.
Back in business....sort of.
Any idea's welcome.
bump
Anyone?
Well I found the ultimate cure: buy a new one.
I will however keep fumbling around with the other one and hopefully as my knowledge increases I'll have a break through.

Auto boot on charge

Hi there, I'm trying to turn my old Galaxy Ace to a standalone webcam with the battery replaced with a proper grid connected power supply.
Obviously, whenever the power goes temporarily down, the device goes into the charging status (green animation).
Instead, I would like to make it automatically boot when powered, just like windows phones used to.
Here are a few common methods which do not work in my case:
simple fastboot command from PC, since we have odin instead of fastboot;
replacement in the system/bin/lpm or playlpm file, since Samsung didn't use it then yet (there is no "lpm" service mentioned in the kernel);
modifications to the charger class launch in the kernel (within init.rc script). I fear that the cross between charging status and normal boot happens at an earlier stage in our device, am I wrong?
The closest solution to my problem was due to the CM 9.1 which happens to be the only ROM that reboots the device if you plug the charger after a manual shutdown. Unfortunately, if I suddenly power down and up the phone (it's like removing both battery and charger), I go into charging status again.
However, this ROM gives me some hope, because it means that the kernel itself can somehow play a role.
I would be glad to hear your ideas. Thank you!
