Hi,
Sorry, this is not a development question per se, but is the Hermes supposed to power on without a battery when plugged in with a wall charger?
I get a red light on the top-right, but the unit doesn't power on. Maybe I have a defective unit. I have the Cingular branded version.
defective unit
yes u have a defective unit.
I suggest you box it back up and take it back to the place you bought it as your to stupid to only this glorious phone.
?
I think you were trying to insult me with your poor grammar?
Yes
You can use the phone without the batter while plugged in. You have to follow these steps exactly...
1. get a a glass of whater.
2. wrap tin foil around your finger.
3. plug in the charger and connect it to the phone. make sure you leave the back of the phone exposed.
4. place your finger with the tin foil on it in the glas of water.
5. touch your tongue to the gold batter contacts on the back of the phone and press the power button.
This method will work..
Good luck.
Sorry man this is not possible. I checked just now coz I never bothered to do it before but today i looked on your question and tested it but nope it is not booting up. Just the red light. So u need the battery to use it.
Some people tries to increase their posts on the forum to become members from junior members. So don't mind and don't become one of them coz you are new to this forum so just be creative and straight. Hope u don't mind if u found my wordings hard.

A good answer - unlike some of our "funny" guys above.
Mike
ok fair point, was just a bit of fun, but why would you want to use the phone without the battery installed and just plugged in?
i believe all mobile phone from htc tend to be able to do this.
Thanks beastfellow
Confirmed. Just tested and neither of my Hermes will start without a battery
all my Hermes work without a battery!
I just plug them in when testing them out or whatever as I don't always want to have the bulk of a battery on them sometimes, and they still boot up and run ok. Must be a lot of faulty Hermes out there.
It shouldn't start without the battery as the battery is an integral part of the device. If anyone's device truly does start without a battery attached -- which I doubt -- there's something wrong with it. Also, I'm not sure why someone would go through all the bother of pulling the battery out only to then plug it in and use it on AC power.
Reading some of the questions here it's become apparent that some people try to do really odd things with this thing only to think something is wrong when it doesn't work as they want it to. It might not be bad advice to read the user's manual to learn about how PDA Phones are supposed to be used, and instead of acting shocked when they don't work outside of those parameters just accepting the device's limitations.
I know we live in postmodern times where everyone has the freedom to define their own realities, but some of you take this a bit too far. There is at least one question a day here where someone is upset or confused by these things not doing what they were never intended to do.
hmmm... it may be based on the charger itself. I haven't tried any of mine yet (will check later today) but I wonder no battery powerup has something to do with using the stock Hermes charger (1Amp) v.s. others

You may be correct. I tried with a USB connection as I was reading the post on the computer. Will try later with the charger at home.
I read somewhere in wiki about fix white boot up screen. One of the ways to fix it was to take out the battery and use the wall charger... However, when i tried it, it didnt work... so i juz hard reset it and it worked =) might be the reason why he is asking about the battery thing... for all the spammer with post counts... lol sad
Tried my 8525 with 1Amp charger & no battery. Got red (not orange) charging indicator and it wouldn't boot. HTH!
heat
the only reason you would want your hermes to boot up with the battery is say for example, you were going to use it as a modem via usb.
we all know that the phone doesnt get hot, the only thing that heats the whole thing up is the battery.
So to get extra life out of your hermes and keep it cooler, run it without a battery!
I would surmise that circuitry in the battery (if the unit got too hot) would reset the phone to prevent the thing fom setting itself on fire.
Update at post #26 (handset returned from HTC alive and well)
Urgent help required please guys - help me rescue my very poorly HD2!
Phone is completely dead at the moment. Battery is completely dead and attempts to charge it are not working - however I'm sure it's not the battery that's the problem!
I've been flashing different radio roms this last couple of days going from 2.08.50.05 to .08 and back yesterday to .05 because while on .08, the back of phone was getting really hot and the battery was draining very quicky. Late yesterday afternoon it discharged completely while I had it on-charge!
Since then it's remained dead! Initial attempts to re-charge saw the orange LED come on for a minute or two, at which time I tried a hard-reset but it froze at the point of making the selection to hard-reset after the brief bootloader screen. On one more occasion the LED came on for say 10 seconds before disappearing again and since then - nothing!
Taking the battery out for all of last night and at least 20 times today has made no difference. Trying to charge it via (original) charger and via usb cable has not worked. No LED, no charge (though interestingly it still gets warm at the back when on charge), can't boot, no response, nothing, nada.
Helpful guy in O2 shop spent 40 mins helping me out earlier today (he's a XDA forum user who flashes custom roms from here too on his HD2). He took his charged battery and put it in mine with pretty much same result! White HTC bootscreen came on for a few secs before dying again. Couldn't start/boot up my phone using his good battery, yet after putting my battery in his phone he was able to begin to charge it, proving I think that, it's not battery that's to blame for this, but an internal fault with the power-unit of the hardware, (and/or perhaps with the charging port).
I'm convinced that the power-unit is the major issue, and that as it seems to be over-heating quicky, then it shuts down immediately from doing anything. I could be wrong of course.
Sorry for the lengthy story guys, but now feeling really low that I can't seem to sort this. If I cant start it up or get to the bootloader screen then I'm not going to be able to flash a stock rom to get this problem fixed under warranty, so as you can see, I'm really frustrated!
Any help, advice, suggestions etc would be gratefully received and much appreciated too! Thanks in anticipation.
Edit: sorry should have said that I've extensively read these forums today and found many similar (but not exact same) threads/posts, hence the new thread.
hapened the same to me, radio 2.08.. to 2.05... white screen HTC freeze....not booting.
my solution was press the two sound boutons at same time, when the screen write HTC apears....them booting at radio specs...them press one more time de 2 sound boutons sf same time....
it solve for me the booting...is strange this issuie of downgrade the radio 2.08... to 2.05..
good luck.

Thanks pack21, but at the moment I can't get it to do anything at all - it won't start, it won't go into bootloader, and I can't charge it. I'd be happy to see anything on the screen at all right now! Thanks again.
since it cant boot why dont you take it back to HTC? They will first have to repair it since they dont know it has been flashed with an unofficial firmware....They might even give you a new device!

Yeah, that's what I'm going to have to do as a last resort, but my fear is that with their tech/tools, they'll figure a way to power it up or get it into bootloader and discover it has a custom rom, and return it to me unfixed. This is almost certainly a hardware fault, as I believe it has always been warmer (sometimes very hot) at the back than it should be, but trying to prove it would be difficult. It would be great if I did return it and they couldn't boot it, but I only want to return it this way as a last resort. Here's hoping someone out there might have another solution.
Can you power the phone up with the charger and usb lead plugged into it?
Have you tried booting wth the SD card out?
If you can at least boot it up then you could try MTTY to see if that helps.
Post your outcomes back up and lets see what else we can do to help.

Thanks for input WB - I note you've helped many others out on other threads with related problems.
Can't power up the phone by any method (AC charger or USB), and because it's got no power, I can't boot it at all. Tried it without SD card earlier, and it didn't make any difference. Even with someone else's battery in earlier, it wouldn't boot up or charge even, so I'm at a complete loss. Always thought I'd need to try MTTY sometime soon - just didn't know my device might die on me before then (and its only 5 weeks old). Any other thoughts?

Hmmm, tough one this.
I know that some of the newer roms are particular about which radio you have installed else you get a problem not dissimilar to yours, ie the device won't get past the boot screen. Yours being completely dead is a new one on me.
Do you remember what radio and what rom were on the device just before this happened?

Yeah, was on 2.08.50.05 until 2 days ago, flashed 2.08.50.08 to give it a try but noticed it was draining battery fast and getting v hot at the back, so reverted yesterday to .05 (but maybe too late, maybe damage was already done, because total discharge happened shortly after that yesterday).
Hey guys (WB and any others with any possible solutions), I need to hit the pillow (11.45 pm my time now and I need to be up 5.45 am), but please keep posting any ideas that you want that you might have, and I'll give them at go first thing at 5.46 am. Thanks very much in anticipation!

Thanks for suggestion WB. I'll pm Kholk in a moment - whilst it could indeed be the radio rom that caused the overheating and/or discharge, it seems that whatever caused it was catastrophic because I still can't get any charge into it, and hence I can't boot it up!
I hope sincerely other HD2 owners do not suffer this same problem at any time - it's proving a nightmare to fix.
My advice to all would be ignore those who promote the idea of allowing your battery to fully discharge - especially if it follows an over-heating handset - you may never recover from it (like me at the moment)!
If anyone's got any other suggestions for getting my handset powered/booted up - I'd be delighted to hear them. Really don't want to return to HTC with a custom rom on it!
The Radio ROM contains software parts that are critical to your device (at least for HTC devices) as it contains the OEMSBL (the radio bootloader) that boots ... ALL!
So, if you flash a wrong Radio ROM (as for example flashing a Diamond radio on Leo, or every radio that is not compatible with Leo: remember that for Diamond/Blackstone/X1/Raphael the radios were compatible) you'll get a totally bricked and unrecoverable (if not using JTAG!) device.
BUT.
You've flashed a Radio ROM and your device booted successfully, so, no errors during the flash process.
Assured that this Radio ROM is compatible with every HTC HD2 (TMOUS and EU), this Radio can't have produced an hardware fault on your Leo: it's almost certain that it is a coincidence that your Leo died with this Radio!
Anyway:
1. Be sure that your battery contacts are sane: check that they coincides with battery contacts: if you swap fast a battery you can do a wrong gesture with your hands and fold youre device's battery contacts.
2. Check the battery LED near the speaker: does it power on? (orange/green)
If the battery contacts are sane and the battery LED doesn't power on, maybe your battery is fault OR it is really completely discharged: on my old NEC e606 if the battery was completely discharged (0A, 0V) I had to charge it "manually".
However, if these two steps aren't helping, try this:
1. Take an AC adapter of maximum 5 Volts, or an USB cable
2. Cut off the end of the AC adapter (or the other end of an USB cable) and connect positive on battery positive and negative(GND) on battery negative.
3. Make sure that the cables are correctly connected and that your power source (AC Adapter / USB Cable) is connected and/or powered on.
4. Mantain this position for 5 minutes: your battery will take some power (yes, it is a really raw charging process)
5. Don't wait more than 5 minutes: it is a raw charging process and it will never stop! (well, not never, but if you wait for too much time, you'll **** your battery!)
6. Battery slightly charged: disconnect it from your power source, take it into your HTC HD2 and connect its battery charger.
If it works, well, you're saved, but I think that there is a fault with your HD2 because for a complete discharge of your battery you have to wait for weeks....or months! Or even years!
If that doesn't work, try with another spare battery that is known to work.
If your HTC HD2 doesn't work even with another battery, RMA it, HTC won't see that you've flashed an HardSPL, a new Radio and a custom ROM because they'll simply replace your mainboard.
Let me know how it goes!
Hope that this helped.

Hey kholk, huge respect for taking the time to consider this serious problem of mine! Thank you for the different options - I'll work my way through them and see if any can bring my HD2 back to life.
I can confirm that I've successfully flashed roms and radios (via SD) and never had any problems, and I think you're right - it wasn't the switching between 2.08.50.05 to .08 and back to .05 - it was probably just a coincidence that the unit got seriously hot and discharged at the same time as I used .08 (hence the reason I had just re-flashed .05 when it happened).
Battery contacts are good - checked them carefully yesterday.
I'm convinced the battery is as dead/discharged as it could be; since yesterday morning I've not even had a glimpse of an orange LED when connected to AC or USB charger (though the unit continues to get warm at the back, but doesn't get hot any more). I'll try your ideas for getting some life into it, and I've got a replacement battery on order, but as I found out with a friend's spare battery, it still won't boot up or allow itself to be charged.
I think therefore that it will ultimately need to go back, but I'm grateful for your assurance that HTC are unlikely to know that I've got HSPL/Custom Rom and Radio on there! Many thanks again for now (its so re-assuring to know that if you come across occasional difficulties, there's some good guys on these forums who will try to help bail you out)!

That's 2 bad nights sleep now, as this happened day before yesterday . Thanks - fingers crossed eh, both for getting mine fixed, and for hoping this is not going to become a common problem for other HD2 owners!
Well, if the device won't power up even with a known good battery, then HTC isn't able to power it on magically. Your hardware got a fault and the only fix for this is replacing the faulty part.
And no, HTC won't desolder and resolder a chip on your mainboard: they'll replace it completely!
I'm sorry for your dead HTC HD2 and I know how you're feeling... I've experienced the same.

Thanks again kholk. Reading what you've written confirms for me that there's not likely to be an easy fix for this and so I should give up on that idea now and just get it returned sooner rather than later for a warranty repair. If anything develops from this I'll be sure to post an update for the benefit of anyone else who might experience the same difficulty. Much appreciated again for now!

I had very similar issue on my X1 when I left it plugged into my car by accident, it totally drained the battery and wouldn't do anything other than blip a red light.
I swapped to my spare battery and the phone booted once, said low battery (was fully charged the day before) then did the same red light.
After much fiddling, it turned out that I had to leave it on charge for around 12 hours for the battery to kick back into life and boot the phone. Then it took a further few hours to charge it again!
Older devices could only be chared with a HTC stock charger (when having a dead battery), cause they delivered a little more power then custom AC chargers (like the one for your BT headset).
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.
Sent from my DROID2 using XDA App
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.
Brandon
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?

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.

Hi all, picked up a GS2 the other day which had the USB charging issue. i.e. Plug charger in and it either wont show up or gives false data and unplug it still shows charging. Also, the battery temp sign showing and battery pull leaves a fully charged battery dead!
Looked around on here and on the net for various causes and possible fixes. These ranged from changing ROM, replacing the USB charging port, calibrating the battery, any number of different things etc etc.
So in theory, it is either a software issue and/or a hardware issue! But to me that made NO SENSE. It couldn't be both, well maybe for a small % of people it could be but for the majority, it had to be something else.
Well, as it would seem from my findings, in my case, it was something else. It would appear that the MODEM/RIL combo is causing the issue.
I tested this on my non-functioning device by flashing a new MODEM/RIL combination and then re-flashing the old one just to check. The old one has the issue, the new combo it is gone!
So IF you have this issue, try flashing a new MODEM/RIL combo and see IF it fixes the problem BEFORE spending any money on repairs.
As IF by some wacky coincidence forum member hawkerpaul has created a thread just today with CWM flashable MODEM/RIL's combo's, find them herehere
Hope this solves the issue for you as well

Hi, I have created a thread regarding this problem few months ago and successfully calibrating using the method found on the last post. But now the problem come back and that method won't work anymore.
From the thread there's someone mentioning deleting batterystats.bin will solve the problem. Is this method valid or not? Now I'm not rooted, and if I decided to root all my data will be lost because I have to unlock the bootloader. Long story short, I don't want to root if that method (deleting batterystats.bin) don't solve the problem.
Thanks in advance!
For my personal experience, wiping batterystats doesn't change anything; you can also read some info HERE
Maybe it's time to replace battery, especially if your 1+1 is not "new"; in order to understand if it is degraded too much keep an eye on the battery voltage all across the battery cycle
Do a couple of long charges (8+ hours straight) with the original charger and the battery should calibrate itself.
Buy another charger / usb cable. it worked for me.
Turn the phone off and plug it in to charge. You should see a battery icon pop up on the screen. Do not turn it back on until it reads 100%. Should fix the issue as I've had that happen across multiple devices.
Wiping battery stats doesn't do anything. It's mainly used for calibrating Android Emulators for laptops so the battery syncs up.
Cheers!
