Caveat - This is my son's phone, and only the recent observations are my own. I can't be sure he didn't do something to munge it up, though I am fairly certain he has not tried to flash it (I haven't either). In any case . . .
I bought an unlocked SMT5600 on eBay about 6 weeks ago. It worked great for about 3 weeks, then went on the fritz. It started by only booting to the red-green-blue OS screen. Removing the battery did nothing to reset it. It was still doing this when I retrieved it from my son. When I finally had time to look at it four days later, it booted once or twice to that screen, but then stopped doing even that. I have since done research online and not seen a similar situation. Other observations - there is no change if I swap out the battery for one that I know is charged. After replacing the battery, when I insert the charge cord (wall plug, not USB to PC) the power light flashes red briefly, then goes black and never comes on again.
Of course the eBay seller is telling me I'm SOL at this point. Before the problems began, I actually bought three more of these phones from the same seller and none has had any problems. My son is not into modding or installing programs, and tells me he has done neither. I think this is likely the case, but it is conceivable he or a friend might have tried something. So I am looking for assistance/direction in what to try next. Although I don't think I have the correct torx to disassemble it right now, I am willing to get the right tools and give that a go to avoid a $150 paperweight.
Thanks, mastman
booting to loader screen
I had this problem, turned out to be a faulty / stuck camera switch
check it clicks well, to check for stuck,
if it clicks well you will need to open the phone to check it with a meter.
not sure why its gone dead now, but sounds a little like a over flat battery.
Ive fixed these in the past by using a 300mah 3v suply for 20 secs at a time to bring it back up to a level the phone will charge.
please be very carefull li-ion cells are very dangerous, try useing a known good battery first in the phone to check its charging
good luck

My SMT5600 choked as it was being flashed, now it won't charge nothing, just a paperweight. Is there anyway to resurrect it? At all?
Thanks
Hi, I have a major problem with my G1, it will not boot up at all now.
To make a long story short. Every couple of days my phone would not wake up from sleep mode. I thought I was having the issue people were talking about here:
http://forum.xda-developers.com/showthread.php?t=528191
So i reverted back to Jesusfreakes 1.5 firmware and it kept happening. So i moved all my apps back to the phone and in fact removed all widgets and really jsut kept a couple of apps.
Anyway this has still been ongoign, usually though i just have to take the batter out and put it back in and we';re in business.
Today though... it's another story. The phone will not start up at all.
I pressed the red button = nothing.
i pressed the red and home button = nothing
red button and camera = nada.
I plugged into the power, a light doesn't even come on the phone. I laeve the battery out or in same thing. I even took out the SD card....
I think the phone just died on me... Anything else you guys can recommend I do?
Take out the battery and hold the Power button for 10-20 seconds.
Plug in the power adapter (without the battery) and see if the LED turns on.
Put the battery back in and see if it turns on.
Does your computer recognize it at all when it's plugged in to USB?
That's about all I know, if you don't see the charging light after you reset it using the power+no battery suggestion, I'd think it would be a hardware problem.
Well I wasn't having any of the waking up from sleep issues. But I did have my phone completely die on me. Same symptoms, it wast responding with anything I tried, and the notification led wasnt working either. I even tried another battery and what not. So this what I did:
1st I pulled the battery out and my sd card for a few moments, the plugged it back in... nothing
Then I let the phone on charge for about 16 hours (some1 suggested this, because messing with the SPL can send ur battery to -110% and takes about 14 hours to revive it. (this didnt do anything for me, but it may have helped I dont know)
Finally I took out my battery, my sim card and my sd card, and let the phone sit for like 10 hours or something, popped my battery back in, and the phone came back to life!
give it a shot, andd good luck
Thanks, i'll let you know in 2 days how it went
in the meantime i called HTC, they seem to know about this issue. He said they'll probably have to swap out the main board but i have to call during business hours for the repair department.
He told me to emphasize that my phone was unlocked so they return it that way also. Since they're putting a new mainboard in i'll ask them to put the rogers one in instead so i can get 3g (I'm with fido in canda 1900mhz)... Let's hope their customer service is extra willing to help out
So my phone was covered by warranty! I guess a dead motherboard does not show the kind of firmware running on the device hihi.
They tried to put a Rogers compatible motherboard in but it failed testing (I have a t-mobile device running on the Canadian network) so they inserted another motherboard. She does not see if it's Rogers or not though but she suspects it's a T-mobile compatible one. They also replaced my antenna.
Can't wait to get my G1 back!!! this Treo 650 is way to bulky
I need help. I messed up my Droid 2 restoring a backup and the battery died during SBF. So I did the Macgiver trick where you connect an old stripped usb wire to the battery so that the phone can be tricked into booting up and being flashed. Since then I've had a question mark in my battery icon. It wont read that battery or the battery that I've just purchased and I get the "Invalid Battery" message and the battery wont charge in the phone. Both batteries are official Motorola. I can't send the phone back as its not under warranty. So I have a few questions.
Is the some sort of workaround/ fix for this? Motorola put software on the Droid 2 since Froyo that reads whether or not a battery is official Motorola product. Can the battery software be hacked/ deleted so that I can use my battery as normal?
Wow, we have this same exact situation like a month ago, and since then my fiancee still uses her broken phone . We did the Macgyver trick also and we got the battery with the question mark. We even bought a new battery and it still shows it, tried reflashing with a fully charged battery and nothing changed. We also tried clearing battery stats none of it is working. If anyone knows anything about this problem please let us know. If you get an answer that cures your phone please please please let us know about it. I actually posted your question on Yahoo! Answers since it was the same exact problem that we had and if anyone answers we will post the reply on here.
Thanks a lot and good luck!
I've got the exact same problem. All I did was purchase one of those external chargers so that one battery is always charged. It is annoying, yes, but its not too bad. I'm also looking forward to see if there is a solution, but I doubt it. We probably all fried the contacts on the phone, but we'll see.

hey, yeah we did the same thing, we bought the second battery yesterday but i have a question, did you try flashing it again with the new battery in? I was wondering if it would work but i want to see if it will before clearing one more time my fiancee's cellphone since theres a fish game that may be lost if we do that.
Thanks a lot.

I've SBF'd multiple times since then, and the question mark is still there. I don't think theres a way around it, unfortunately. Personally, it's not really a big deal, but it may be for you.
I just really hate it because I have no clue when my battery dies.
Never had the issue, but one thing comes to mind..why not root, install clockwork recovery and then clear the battery cache?

They said they already tried that.
What exactly is this Macgiver trick? If you have a link, or some info on how it's I might be able to shed some light on this for you guys
The D2 battery is 3.7 volts; USB is 5. You probably blew out the A/D channel used to measure battery level.

Ah, I see so they're hooking up the USB straight to the phone...found it after a little searching...
But i'm curious, wouldn't that only happen if the wires ended up touching the other two terminals, and not just the outer (+) and (-) ones?
Will getting a new oem battery work?
No, replacing the battery will not work if you messed up when connecting the spliced USB charger + and - to the wrong terminals in the phone.
I have exactly same problem. I sliced the usb cable to revive my Droid X when the battery died during sbfing. Now my phone survived but Im stuck with question mark on battery icon. I flashed reflahsed and flashed again but no luck. wiped batt stat but no luck. Tried new OEM battery, no luck.. Put the batt in the freezer for 10min but no luck. I ran out of all the possible solution.
Now I just got the external stand along batt charger from ebay with 2 extra batts. I just carry extra battery since I dont know when the phone will go dead..
I would love to find out if someone can fix this issue. I still got 6 mo to go before I can upgrade.
I HAVE A SOLUTION (worked for me):
When doing the "Macgyver Hack", I jammed the USB wires into the battery. This pushed the metal spring terminals out. After that, the battery terminal springs don't all touch the connectors in the phone.
Take a needle, and carefully pull the battery's metal springs toward each other.
This worked for me.
Also, try this:
Remove battery and unplug phone. Plug phone in (without battery), then turn on (some phones will turn on without a battery). After the logo comes up, insert the battery. This made my phone recognize the battery and get into the OS.
Once the battery is recognized and you can boot to the OS, root the phone and get the battery calibration app (and use it).
I have a Motorola Defy, and used the Macgyver hack, then had the question mark problem for days before figuring this out.
jodaboda, Thank you a ton for that. I've been searching and trying out things to fix this and this is the closest I've come.
Although the Droid 2 doesn't boot up without a battery, I've had to the Macgyver Hack to get it to boot. The battery calibration app reads 100% charged when I am using the Macgyver Hack and is showing that the battery is charging. I'll tell you if it works once my battery is charged and I calibrate.
I wasn't able to get it to work. I think there is potential but my phone eventually died and it wasn't able to fix it. That app can measure the volts correctly tho, which means we should be able to get the battery working again somehow.

I don't have a nan back up from recovery but have read on another thread that you can also fix this by doing a restore of a back up through the recovery from a time before you have had the battery ? issue.. several people have also mentioned that it worked for them.. in my case I don't have a back up before this issue so I cannot confirm.
my phone died noooo
bumping in case anyone has a solution?
please. pretty please.
tried methods above, phone wont boot unless plugged in... i don't care i can't tell what % its at, but i do care it wont boot off battery power.
Tried 2 Ways with no Luck.
1. Power button + volume button down Long press less than a min. ?
2. Plug in for a day or more. ?
Gotto try jadaboda's tip.

The phone is my MiL's. This past Friday she was heading out to run some errands and picked up her phone. She said the back of it was so hot that it almost burned her hand. She pulled the phone out of its case and was able to get the back off and pull the battery. When I got in from work I tried starting it up but the battery seemed to be dead. I plugged it up to a charger and got nothing, but it did start heating up beside the camera; it does this whether the battery is inserted or not. Nonetheless it will not turn on either with or without the battery or on the charger.
Anyone else run into this? Is the phone toast? We have already got her a replacement (Moto G4 Prime edition) but I want to give this thing one last shot.
Try getting another battery, just to try.
Also can u boot to fastboot mode (power button + increase volume button)
Otherwise i think its toast
Hey all...took a look through the forum to see if this has been asked but I did not see anything so here it goes. I have an older S7 Edge SM-G935W8 (not rooted) that I love. I was using it a while back and the screen "glitched" and the unit turned off. I was at the cottage with no access to the internet so I tried a soft reboot...nothing happened. After I got back, I tried to Forced Reboot, charging, Safe Mode and Recovery mode methods but I get nothing. There are no lights, no vibrations, no nothing. I have left it on the charger for 24 hours (no light) and still nothing. There is absolutely no sign of life. I'm not inclined to have a tech look at it since it is just a media phone (no Sim Card) and it would probably cost more than the phone is worth but I figured I might check here to see if anyone has any ideas. Maybe dead battery, or motherboard?????? Many thanks in advance.
To be sure what you are going to have to take to a technician to analyze it. A battery shock may be required to see if it recharges or it may be a more serious problem, such as a short on the motherboard.
