wont boot at all.... - Hero CDMA Q&A, Help & Troubleshooting

new here, hopefully not posting a duplicated post before...
i purchased my hero200 cdma in china...
it said that its a modified version (supporting sim card...)
actually i dunno much about that....
i fresh it by a modified rom that build from aosp0523 from here:
(Sorry for this is a Chinese thread)
www[dot]apktown[dot]com/forum.php?mod=viewthread&tid=817&extra=page%3D1%26filter%3Dtypeid%26typeid%3D18%26typeid%3D18
it works totally fine until last night, i was chatting with a friend in whatsapp
and try to recording my voice and send to him....
in the progress in sending him the voicemsg, the whole phone suddenly blackout
after all, it wont boot at all. At that time, i discovered that the battery is quite hot, i dunno whether it matters.
by chance, it might vibrate few times and the LED at left upper corner keep flashing green light. and also, by pressing the +volume button in the mean time while i plugging the power adapter in the phone, it vibrates 3 times.
no matter what, it just wont boot in, not even recovery nor htc logo...
any suggestions?

This happens to me sometimes. The excess heat makes the battery discharge at a very rapid rate. Try this: unplug the charger and remove the battery for at least 1 minute. Then put it back together and if the red charging light comes on like it should, let it charge for a bit before you power it on. Then boot like normal, all your data should still be intact.
Good luck

battery broke my flash procedure??

Hello folks, this is my verry verry first post so sorry if its not conform the rules
a few weeks ago my phone fell on the floor, and the battery acts weird.
It shuts off after i call 3 minutes claiming the battery to be epty, but when i remove the battery and put it back in again, it shows as full.
two days ago i messed up my phone and i thought well i flash it back
(note: i flashed my madonna before and it always went well)
But now, it flashes all the way to 80% or sometimes even 99% and then it shuts off, starting to blink the tricoloured bootscreen on and off.
when i put in the AC charger it stops blinking showing the tricolour screen steady.
ive been searching for ways to flash the phone from SD-Card so i can kepe the AC-Charger connected, but all i can find on the net is a way to backup the old rom to SD-Card and reflash it from that?
But.. i cant access the old rom anymore?
its from the wizard wiki page
I'm seriously thinking i have a rather expensive paper press, please tell me there's ways to fix it using SD-Card?
i cant order a new battery untill 3 weeks from now, which i really cant survive without my companion hehehe
just turn your phone on and flash it with rom again
The problem is your battery doesn't have enough charge and might be going bad. It will charge on the wall charger even though the tricolor screen is showing, but I believe it charges slowly. Try letting it charge overnight.
I had a similar problem and now my phone is fine.
You can order a new battery for under $10 from ebay.

same problem
I have the same problem. Loaded the battery for a whole night, but still it stops at 80% or so....
My battery had huge powerdrain, especcially using bluetooth, before flashing.
I orderded a new one, still waiting. I'll let know if it soves the problem.
If there are any onther experiences i'll be happy to read.
well, so far no luck.
sopme say, the printplate broke, (the greenish thingy with all the odd meganics on them?)
other say there's a transistor mallfunctioning, and some others even dare say its nokia's fault (dont ask me why!) for now, i simply believe im stuck with a rather expensive paperweight
even tho i tried charging it for 3 days nonstop, put the battery in the fridge, nothing worked, i guess ill mail T-Mobile seeing as how im due to prolong my contract, amybe they can do me a favor instead of making me wait a few more months
how to reecharge battery
1. get a hold of a USB cable for the computer(one that you dont usually use)
2. (not connected to the computer) you would need to cut off the end that plugs in you phone and then you will see 4 different wires. you will only be using the red and black wire so just strip those two.
3. take the battery off the phone, plug you phone to the wall charger w/out the battery, and connect the USB wire to you computer(make sure the red and black wires are not touching)
4. touch the red and black wires to the positive and negative end of the battery(the battery has labels of which one is the positive and negative part)
5. hold it there for 10 secs then quickly transfer the battery into the phone. after 3 secs of being in the phone, it should start right up.
this steps also depends on how long your battery has been dead. the maximum time you would do this is 3 times. after that and still not working, thats a confirmation of your battery being a done.

Dead

I let my phone battery die, and now I can't turn it on.
Usually I get a red light which goes when the battery is in if its charging.
Sometimes I get a red light even when the battery is in and its charging.
If I do a soft reset, sometimes I get a flashing red light on the sides but then nothing.
I managed to get it back briefly by doing all manner of hard resets and soft resets, and taking the battery out and putting it back in over and over again for about half an hour...
Then I left it charging for half an hour or so and carelessly allowed the battery to die again because I needed to take it with me somewhere - so the same thing has happened again.
I left it charging overnight but I'm not having any luck with it this morning... any help would be much appreciated.
yeah similar problem here. my phone warned me the battery was low... i ignored the warning and used it until it died completely. then it wouldn't turn on. it was late so i just plugged it into the wall charger that came with the phone. i dont think it charged cause in the morning it was still flat. if anything i think having it connected to the charger while not charging drained the last a few drops of juice out of it. had a number of confusing red lights coming up in different spots at different times.
i read on here some guy managed to charge it by getting 3 AA batteries and connecting them directly to the battery for a couple of minuets. i did this and managed to turn the phone on! hoooray!
it had 1% and died in less than a couple of minuets even though i had it on the charger. tried the 3 AA battery trick again but to no avail. i think my battery is dead.
i'm pretty certain i will need to get a new one. i hope you are able to get yours working without buying a new battery.
im really annoyed the Sony Erricson batteries work out to be close to $100 AU. i would prefer to get a legit one... but does anyone have any experience with unofficial batteries? are they any good?
Sorry you're in the same boat... Ericsson really should have made this phone so that it can run out of battery.
Interesting - tell me more about the 3 AA battery trick!
sounds like the cells in your battery isnt balancing hence its dying...think you'll need to buy another one / or at least try another one to make sure it is and not the phone...
Hmmm... I fiddled and pressed buttons and took out the charger and put it in, and then kept pressing the on button while I was doing something else...
Suddenly it made the click noise, but it's not back yet.
It seems to have crashed on the 'Sony Ericsson' start up screen with the green logo.
I don't know if it's charging or not, so I'm not sure whether to turn it off to try again (at the risk of losing the battery), or leave it to charge as it is before I turn it off and can't start it again....
At least it's progress
There are a couple vof threads with many solutions. Look for them, they are very useful.
Yeah I've found a few - Thanks... just nothing they mentioned has worked yet
I think the problem I have may be a slightly different now anyway...
Now, if I unplug it I can't turn it on, but if it's plugged into my computer cable I can get it (every time - after about 3 minutes) to go to the Sony Ericsson loading screen but no further (as if there is no hard reset file for it to load). I can do that by plugging it in, then doing a soft reset (which produces flashing lights on the side) then holding on until it clicks (usually trying that a few times). When it clicks the lights on the side flash and it looks like it charges for a second before the lights go off and its just hte loading screen. I left it for 5 minutes and it turned off completely. Nothing happens if it's plugged into the wall cable at all.
Have you any idea how I might be able be get something to load after the loading screen?... Or any thoughts as to whether you think it's likely to be charging when its on that screen?
Thanks
Hmm... It seems you have a software problem as well.
Here is what I would do: get another battery (fully charged) and try one of these hard reset methods:
http://forum.xda-developers.com/showthread.php?t=437607
Something should work...
Sweet - I managed to get the hard reset screen to ask me the question about going back to factory defaults... after that the lights on the side are coming on to show its charging....
I guess there's a chance that when the battery is charged it'll have the juice to get past the loading screen... I hope anyway.
Wow this title gave me a heart attack almost
i thought someone is dead
plz i need help
hello good day plz i neesd to flash my htc p3600 and sony ericcson cybershot i need a software i can use to flash them plz help me any body that has an idea
just ordered a 1800mAh mugen power replacement battery. should be here in about a week my old SE k800i will be getting a bit of a work out in the mean time.
i think this break from unnecessary technology which I'm far too attached to will do me good. I'm far too materialistic.
hope you manage to get your battery going again!

My D3 died! :(

:crying:
Opened bike race when the screen froze while opening the game (dark screen).
Pulled the battery but when I boot the screen goes on after 3 secs, stays on for 2 secs then goes into dim mode (i can see it's still on).
However my phone doesn't boot since I don't get any whatsapp messages. Normally it should boot to SIM screen but other apps should run.
X+power or M+power doesn't change much.
I'm guessing mobo/cpu fail.... any ideas?
:crying:
edit: It turns on when I put in the charger without battery! Dead battery?
If you put the battery flat on a table does in spin well. Batteries bulge when they are done. The better the spin the worse it is. It's odd the behaviour that can happen with a end of life battery

Well now I'm not so sure what it is.
When I put the cable in without battery the M logo appeared and then the charge screen with a ? in the battery (because there was none)
Then I put the battery in and it started charging.
After a while I tried to turn it on but same problem - just a black screen when power it, no logo whatsoever.
Now I can't get it to work without battery either...
edit: I don't think it can be the battery, because the screen stays on (it has power apparently) and it doens't work with cable connected either
But I also don't see it being the screen as it never vibrates like it does when you boot it.
How did it just show the charge screen before and now it doesn't??
I made a vid of what happens when I power it:
https://dl.dropbox.com/u/22072961/Droid 3/Video0067.mp4
The Droid 3 and Bionic are similar phones, and it turns out that the Bionic will not boot up without a battery - it will hang at the Moto logo even if plugged in. See this thread at androidforums.com: http://androidforums.com/motorola-d...via-adb-unable-boot-up-phone.html#post5463741
So, it may be that you just need a good battery pack in order to get to Recovery/Bootloader/Fastboot etc. if the phone will not start or start to Safestrap.

The worst part is using my Samsung Jet "Smarter than a smartphone". Which isn't even close to a smartphone because it doesn't have any of the OSes = no apps
In my XT860 in its power when it reaches the lockscreen, restarts or shuts.
When I put it to charge my battery shows 0% and charging. When I go to Safestrap-after several attempts-, battery shows 99% or sometimes 80%.
I think the cpu wants to leave the world of technology :crying:

I tried the stock cable that came with my phone (USB) but nothing happens. Screen doesn't even go on.
The light next to the microUSB does go on.
But my phone has never booted with USB (0.5A). When my battery was 0% I always needed a socket charger because it wouldn't go on and charge with USB
When I then insert battery and try again with stock cable same happens as in the video

Ah I see. Well I'm not in the US so getting one would be a PITA
I'm gonna try my spare battery (original battery) tomorrow. It that doesn't work it must be hardware related because I haven't flashed or done anything to it so it's not softbricked or something.
edit: it team blackhat do send to europe? How would this be different from trying another (working) battery?
Try cutting a USB cable open, hook the red wire to the + of the battery and - to the black and let it charge that way. Also, do you have any MicroUSB charger? I have one for a BB Bold I used to have that delivers I think 1.25A and it could charge my phone from dead (obviously not now with the flex cable having a rip in it).

The little light next to the USB port is the 'It's still alive" light that Moto put in when the battery is completely dead. It's to let you know that the phone *is* charging, just not high enough to boot the phone (i.e. when you let the battery completely die).
WHY they did not make it a standard charging light (like the D1 and D2) I don't know, but that's the only time it comes on. A quick flicker on USB plugin, or when the battery is dead. The light goes out when it gets enough power to boot up.

Well, it's not charging because there's no battery , the light it still on
I really dont see how its the battery because when I put it in without cable the screen turns on and stays on for as long as I keep the battery in. So it HAS power. Today I'm getting my spare battery and we'll see I guess..... don't have my hopes up
My daughters D3 was doing the same thing,me being not ready to dig into a phone yet ,took to a local repair shop, they checked it out and found it had a bad LCD,should get back Friday, sorry for the bad news,just thought you would like some insight.

Thanks. But should it turn on when the LCD is bad? It doesn't even boot else It would vibrate once.
Can anyone confirm that the phone should boot when I remove the LCD alltogether? Else it might be a bad LCD or loose connector

[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.

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

[Q] [Help Thread] Nook HD not booting at all

I recently went on a 3 month trip. Before I left, my nook was working perfectly fine, when i got back, it didn't work at all. It's not dead because i left it plugged in overnight but it still didn't turn on. when i plug it in the LED goes from orange to green and then off (or green to orange, i can't remember). The screen doesn't turn on at all. I can't get to recovery either.
This is a Nook HD, I believe it had CM11.
:crying:
Can this be fixed
or should i plan it's funeral
Same here
The same has happened to me. Screen doesn't turn on, but there is power, I can play it into my laptop and something is there, just not enough.
Good excuse for a new tablet!
It can be fixed. I've done it before. It has to do with the fstrim not being compatible with certain hardware versions of our device. If I can remember how I fixed it, I'll post it here. Trying to fix mine (again).

If would be fab if you could fix. Seems to be a common issue
I was able to fix it. YMMV.
1) Make sure the Nook is completely off and unplugged
2) Take out your sdcard
3) Hold down power button until the "battery depleted" icon shows, then promptly plug in the power before the icon disappears.
4) Let it set. The screen will go black, then it will attempt to boot and get stuck on the faint black screen, but this time, the charging light should stay amber.
If you want to be safe, wait until the device reboots itself. That could take hours though. If you're plugged into the wall wait at least 30 - 45 minutes before holding the power button down til it shuts down and then rebooting it (with the sdcard inserted).
Good luck, I hope it works for you.
EDIT: Also, I've read this may also have to do with wifi sending the device into some sort of strange bootloop when the screen is off. I personally believe it has more to do with the fstrim of JB but perhaps changing the wifi sleep policy may prevent this issue from happening again. I'm skeptical, but figured I'd pass that info along if anyone wants to try it as well.

If you want to be safe, wait until the device reboots itself. That could take hours though. If you're plugged into the wall wait at least 30 - 45 minutes before holding the power button down til it shuts down and then rebooting it (with the sdcard inserted).
Good luck, I hope it works for you.
EDIT: Also, I've read this may also have to do with wifi sending the device into some sort of strange bootloop when the screen is off. I personally believe it has more to do with the fstrim of JB but perhaps changing the wifi sleep policy may prevent this issue from happening again. I'm skeptical, but figured I'd pass that info along if anyone wants to try it as well.

Not sure we have the same problem. My screen doesn't come on at all, I don't get a battery depleted icon, no matter how long I hold in the power button. The only sign of life I get is when it's plugged in, when it goes from orange to green after about 10 seconds.
Thanks for the help, but I think it's a lost cause.
YMMV. But mine was the same issue. You should be able to get the icon by holding the power button down for 5 or 6 seconds. I'd say just eff with it until that icon appears. Try different button combinations. I used power and home trying to get the icon to show.

Anyway... since people are continually running into this kind of issue...
Give or take 21 seconds after turning orange it turns green during actual boot cycle into rom
Give or take 10 seconds after turning orange is cwm internal recovery.
After about 10 seconds the charging screen image disappears.
The charging screen image once finally no longer may not show up again until full power off/on (holding power button > 10 seconds or full battery discharge). Unplugging and plugging back in does nothing except making the device look bricked if there's too much light shining on it.
Device may not automatically leave the above state under a specific situation(s). May still need manual full power off/on.
Guessing 10 seconds could also be something else during the early/late boot process or other. The light changing color though should indicate that something is indeed happening.
Light should stay green during the boot process if its completely and fully no questions asked 100%. If you go based on that than yours doesn't appear to be completely fully charged which should either mean its turning on and using battery or not charging correctly.
The light turning off is curious. The device could be shutting off. If light comes back on a moment later then the device has rebooted. if the light stays off = n/a.
If its booting into recovery then the device would be available via adb. At that point it could be further evaluated.
On the off chance the screen was damaged it should boot and usb should be available via computer as well as adb.
If not then its probably toast unless its simply not getting a good enough current causing mislead battery stats and/or not enough energy to get to charging screen (bad wall power adapter in use, damaged power cable - though could be bad battery, defect, damage or whatever). OR there's some major error on behalf of the user happening (think should have tried that in the morning not while 1/2 asleep or came home from long trip and forget how that works).
Maybe the only other things are the emmc brick bug, was left sitting in the sun or heat or ocean air or other physical damage/defect even to the power port as well.
Or maybe it was mad that you left it. Shouldn't have hurt its feelings you know. At least its not crying battery acid on you.
That should just about cover everything except for the things not mentioned. Since its your device, you decide what happened.
Its complicated so anyone see any improvements, clarifications, or mistakes? Please put it in a post.

Bumping this thread to make it aware that there is a real answer. I have been able to duplicate this problem and rather easily too.
The problem is indeed from bad power. The device isn't receiving the correct amount of power needed to charge and start from a fully discharged battery.
To safely* duplicate this you can use a usb extension that isn't fully connected to the nook power cable. You may need to fully connect it first then slowly disconnect/connect till the light turns green when it should actually be charging. It won't actually charge in this state, or if it is, its very little and the battery percentage will continue to drop.
Leave the cable as is and unplugged. After the tablet is fully discharged, connect the usb cable. The light will change through the modes and turn off. The device will not turn on.
There are probably other ways to cause the problem like for instance a portable usb battery that doesn't put out enough juice (not the orange kind). Etc.
* It didn't hurt mine, but not my fault if it breaks your device.

I actually ended up fixing it yesterday!! I haven't touched it in about 3 months, and I was planning on just throwing it out getting rid of it some how. For the heck of it, I decided to plug it in, assuming that it was gonna go through the same process. But this time it went from green to amber, but it never went off. So I pressed the power button and the battery icon appeared. This was a really good sign. So I left plugged in for about 5 to 10 minutes then tried to power on.:fingers-crossed: As soon as I saw that '' Nook" boot up screen, my heart stopped. It booted up perfectly and I almost blew up from excitement :victory:. So I then flashed the stock firmware back onto it, so this would never happen again.
I guess the battery had to be completely depleted or just had to cool down. Idk but either way this was one heck of a miracle
So I recommend for anyone having this problem to just leave it off and don't mess with it. I wouldn't say for 3 months like I did but maybe test it each week or wait a month if you have good patience
Wow. Man, that's awesome! Glad you posted that update on it. Thought if you had posted an update it would be the opposite as in trashed it
Actually, I guess only you could answer if you had also moved/unplugged the power cable from the wall adapter or put it into a different wall adapter, etc. Thinking there could have been a difference there.
These modern day devices are so finicky, guess anything is possible. Like you say, maybe sitting without power is another answer.
From some experimentation I have etermined that your power adapter (that plugs into the outlet) is the issue. It does not like to be leaft plugged in indefinately. It will continually use power even when the nook is not plugged in.
Also, if you use a differnt adapter you will have the same problem unless it is also of the exact same voltage and amps.
