Did I brick my Ipaq 614c?

Today in evening my cell phone switched off after the battery died.
I put in the USB charger and once it started to charge I instantly at that moment switched it on, it showed the blue startup screen and vibrated and shut off again (I presume it was not charged enough at that moment to be switched on), I again instantly switched it on as it was charging, it showed the blue screen again, gave a long vibrate and shut off. Since than I have not been able to switch it on at all. It dosent even vibrate or show the blue startup screen at all.
The red led on top is on as it is in charging mode, but it has been like that for past 6 hours, after few hours the red led turns off automatically so I had to unplug and plug it again to turn the charging on again.
I have been pressing the power on button but nothing happens, I even tried doing the hard reset but nothing happens. Except the red charging light it has been dead for past 6-8 hours even after I have been charging it for that long.
What should I do?
And the bad thing is I live in US and got this phone from UK, so I dont think I have any warranty as www.expansys.com mentioned it earlier that this is UK based phone and their is no warranty in US.
I'm not sure you can just brick the hp by charging it. Try the following:
1. Remove the battery and plug in the charger. The ipaq works without battery only on external power.If yours doesnt, then the battery isn;t causing the problem.
2. Remove all sim and micro sd cards if you have put any. Leave the ipaq only as it is out of the box.
3. If it doesnt turn on either way, you have to try to restore the rom.
How to do that? Easy.
a) turn the device off. put in the battery and plug in the charger. Then press the record buton (on the right, just under tha jog wheel or whatever it's called)
and while holding it, pres the power on. It should turn on and over the blue screen ypu see "clean boot" Just leave it, take a deep breath and wait. DO NOT TOUCH IT until it boots windows and asks you to tap the screen. IF nothing happens you have anther option - go to the HP site and find the rom update - it's 53mb and it's a little tricky to find. Then turn the device off and run the rom update utility from PC. If this doesn't work, then i sugest you contact HP support online chat and ask for help (Not likely to get any).

Just do some research. Google it. Go to the hp site and try to find someone with the same problem.Don't just sit there. You have INTERNATIONAL WARANTY. In the worst scenario you can send the davice to HP in the UK and get replacement unit. If you haven't dropped, spilled on with water or charged with higher voltage(which i think you can't do in the US, as you have 110v circuits.) you can call HP support in your country, bring it there and just ask for replacement.
Don't try to flash it with roms provided on the site - it's not for first time users. Read, research and ask, before destroying your device.

When I tried step 1, all LED lights just started blinking, I tried powering it on but nothing happened.
Tried restoring ROM by pressing the buttons you mentioned but nothing happened. No power no clean boot, just switched off.
I downloaded the Rom from HP website and strange thing is to download it I selected the option on HP Website 'Detect my device' and they did detected my Ipaq 614C, but after running the file it goes to the screen 'Please wait shile the device state is verified' and than it fails to recognise my device!
Even when I know everything is firmly attached.
What is the PC you're using. Can you try to plug the usb cable in another slot.Did your ipaq work at the beginning.
Do you have Active Sync 4.5 installed? XP or Vista. XP is recommended. Is the update 53Mb (not the 1 mb one). When having hardware problems, the trick is to alter the variables - use different connectors, cables etc, different settings and so on. This ipaq is cheap for a reason - there are lots of faulty units, but that's why waranty is for - if you have a document for the purchase, you have international waranty. That's it. Before going to HP service center, try all possible options mentioned here again on a different PC with all the software needed - Active Sync 4.5 and usb drivers that may be included in the CD that comes with the ipaq. If the HP website recognises the devie it's almost sure you don't have a brick, as it probably verifies the EBOOT - the most vital part of your device's memory. Try upgrading a few times no matter the error. Restart the pc and so on. My advice - ask for online support or just call HP support. Be insistive but polite. If they say "go to the service center or something like that" just continue asking. Write down your case ID. Use online chat help on the HP site, even though your device is not listed, choose IPAQ 500 or 214 and just enter the SN and PN (on the back, under the battery) and Tell them your device model.

Probably WAY too late but I've just acquired a sickly 614C which I've nursed to health.....
There seems to be some bizarre issue with the charger in the 614c so that if the battery level falls too low, it requires a mains-connected USB charger rather than just the USB port on a pc/laptop.
If your 614c is the same as mine, the red LED will be pulsing very slightly when connected to the USB port but a solid red when connected to a mains USB charger.
Once the LED turns amber, it can then be connected to the USB port for further charging. It looks like it just needs an extra boost when the battery is completely flat.
HTH!
hi
i had the same problem when i left my phone uncharged for over a week. after reading about the same issues some of us encountered i came up with a simple idea that worked. i just connected the charger to the phone and long pressed the reset button (over a minute) till the red blink dissapeared and slowly the amber one took its place then i left it to charge.

No syncing no charging

had a similar issue which...i had to send my hd to htc, the mother baord was replaced,, make sure u turn bak to stock rom inorder for it to be under warranty
tc
Please check the following:
Unplug your device. Turn off (no standby, turn completely off by long-pressing the power button) your HD and start into bootloader mode (hold down the volume down key while pressing the power button). You should now see a screen with four coloured bars in the background (red, green, blue and white, if I'm correct). Wait a few seconds until it reads "serial" at the bottom. When it does, connect your HD to a USB port - if your USB port still works, it should switch from "serial" to "USB"! After connecting, wait a few seconds as the PC might install some drivers first...
If it doesn't switch to "USB" I would guess that your device has a hardware fault...
Good luck! Crossing my fingers!
thank yu for yours suggestion but my phone is not under warranty now and i have given all my pained earnings to purchase this ppc c and also my rom is not the original one so can anyone show me a simple way out thre to come out of this stucked ups
Sorry as i cant bear all the conditions this two of my friend shown to me sorry

waiting and expecting for reply plzzzzzzzzzzzzz help me out here
does anyone knows the conditions by which the mother board become defective or mini usb becomes unfunctional waiting for replyplzzzzzzzzzzzzz
not really much help, but why isnt your phone under waranty?
afaik, the touch HD didnt come (to the UK atleast) till around nov/dec 08 - less than 12months.
also, didn't you think about insuring the HD - not exactly a cheap phone?
-change USB cable - faulty?
-check 'charge via USB' is set on the phone - this wouldnt affect mains charging though
-hard-reset phone
-remove all devices from the phone (sim, battery, SDcard), leave overnight, and try to see if it will charge again in the morning
Charging when Switch off But not charging or syncing whed on
removed all devices from the phone (sim, battery, SDcard), leave overnight, and try to see if it will charge again in the morning
This Trick Worked for Me to Some Extent
Now I can Charge Blackstone By Using usb cable connected to pc but only when the mobile is switched off
When Switched on it doesnt charges
And also It doesnt sync with the pc
Plzzz Help to overcome the next step out
U R the MASTER.....Atleast for me and my blackstone
Waiting for Reply
Your phone may not sync with pc as your usb drivers may need updated. Also check that usb connections has been activated in activesync connection settings

You may wish to try this. Go to system settings, power settings and make sure you have unchecked "when device is turned on, do not charge the battery when connected to the PC".
Good luck

sorry my server is hanging out so i repeated it

Upgrade may fix it
i think if we assume it software(driver actually) error the reflashing to original rom or upgrading may fix this(as i have tried hard resetting)
just requiring urs opinion and the way to upgrace in this condition
thank plzzzz reply
When in bootloader does bottom of screen say 'usb' or 'serial' when connected to pc? Have you updated drivers on your pc? Have you tried using a different usb cable? When connected to either usb or charger, does LED at top of phone turn on? Changing rom shouldn't affect this, so I don't see a reason for flashing a new rom just for this.
Same issue
I had the same problem, sent the fone for warranty, which is replaced now..............
Ok but i want to just know can i upgrade or not

[Q] HELP!!! Please read HD2 WONT CHARGE / SYNC

I looked through similar threads but have found no solutions.....
My TMOUS HTC HD2 randomly stopped charging, even when plugged into a wall charger or computer. No orange light even displaying when hooked into the charger when powered off. I have bought a new battery and charger and still doesn't work.... Whats weird is that there is usb connectivity (only using MAGLDR v1.1 with an android NAND android rom installed in usb android flasher mode). I am guessing this is a hardware issue so i am trying to return it to stock, the only problem is that windows mobile device center 6.1 x64 on my windows 7 desktop will not recognize/sync with my HD2..
I would like to return it to stock so i can send it into HTC for repairs (if possible)
I would really appreciate any possible help
hold the volume down button when turning it on. You should see a screen with 3 colors. At that point, you can flash stock.
I have done this but the only problem is that the computer wont recognize it and the phone stays in "serial mode".
Any thoughts?

Hello every one,
When I plug my Omnia 7 with my laptop, it appears the message "USB Device Not Recognized. Unknown Device (Code 43)." I have tried different ways posted in this forum but non of those worked. I tried to restart my pc, plug off battery, hard format my phone, tried in different laptops, and the other methods, but non of those worked.
I need help please if anyone could tell me what to do I would appreciate.
Try reinstalling zune, maybe even reinstalling sammy usb drivers.
Sent from my OMNIA7 using XDA Windows Phone 7 App
I have to say .... we can spend hours understanding these windows phone
I do not know why a windows phone cannot be synced with a windows computer. Am having the same problem. My device appears as unknown device in Device Manager. I tried to update the drivers from Zune folder, but it does not find the correct drivers there. Any help would be so appreciated.
Thanks a lot.

I think I can help - it may be the BATTERY!
Hi - I stumbled on this thread by accident but had a very similar problem - I will look up the Whirlpool thread where I wrote about it as it was a while ago - but similar symtoms all fixed by replacing battery. _ i dropped my Ominia briefly into water.
Here's what I wrote in Whirlpool forum on 2011-Oct-31 (can't post link as new member) Thread Title "Samsung Omnia 7 i8700 - Part 2"
My beloved Omnia 7 took a very quick dip in the pool on the weekend. Life lesson learnt: "Do not put phone in top pocket as it will fall out."
Anyhow I grabbed it straight away and turned it off – dried it off etc – I was amazed it booted and runs BUT things are not good.
� Phone works normally (all functions, wifi, apps, OS etc.) on external charge either AC or PC USB
� Phone works normally on battery, but it keeps playing an alert chime, will not sleep, and in Settings / Battery Saver it flashes on this screen � and it does not sleep as whatever it�s alerting on prevents idle.
� Goes to sleep when on AC/USB charge.
� After plugging into AC/USB, and unplugging from AC/USB, phone runs normally, believes it is being charged, does not play alert chime, but does not sleep
� Does not interface with PC via USB � plug into USB causes �USB Device not recognised� (tried different cables/PC�s)
� Does enter download mode, but USB not available.
At a long shot, it may be the battery. I know I could buy online (risk it won't be the issue). All I need to do is a quick battery swap test but need a spare battery.
WHAT A MESS. Let me know if you are a Brisso and wouldn't mind sharing your battery for 5 mins....
If replacing battery fixes the problem then GOD knows what Engineering Samsung/Microsoft is upto

I had the same prob here and windows can not recognize my Omnia 7 any more after it caught rain.
I had the same problem on my Windows 7 (64 Bit)
Unknown usb Device , lot of posts have found and at the end it was USB-Cable !!!
The problem was in the length of the cable, with long (1m cable) i can flash but no connection over Zune, after i take cable from my Nokia 15 cm short cable it works without any problems.

What Windows are you using, do you have original ROM on your Omnia ?
For example if you are using some other rom than original , that there you have changed settings for USB port (In Diagnose Mode you can check this)
I am on original German T-Mobile ROM, exact same issue, no cure for now. Looks like an end of life for old good Omnia ...
But I did force update both 8112 and 8773 yet before ZUNE actually suggested the update .So not really in a position to complain.
But if anybody here did a "fully legal" ZUNE update (no flash no forced) then it means that the update itself is a problem and MS / SAMSUNG are responsible (not that it ever changed). Did anyone on OEM ROM with the issue upgrade in a fully clean way ?
Just now noticed - this is similar to the problems mentioned in another 2 threads hot here - just in another case people experienced only annoying "alert ringing". Looks like some of us get hit more severe, others less. XDA gurus - PLEASE spend time on this ! This looks as a massive desease case, last hope is XDA.

[Q] Nexus 7 2012 does not charge, does not boot to bootloader - please help

Hi guys,
I have a Nexus 7 2012 which has become almost completely unresponsive.
Possible cause:
Last thing I remember is that I had it in my pocket and when I looked at it later - it was in bootloader mode. I pressed the power button and since then I have not been able to wake it up.
The device does not charge because I cannot feel the battery to be warm after a whole night of charging. I cannot turn it on no matter how long I keep the power button presses. I have tries two minutes on the clock. I cannot enter into bootloader by pressing power and volume down, even though I keep pressing them for two minutes also on the clock.
So I removed the back cover and pulled out the battery connector. Reconnected but there has been no change in condition.
The device shows the following signs of life.
When the battery plug is pulled out I connect it to my Windows 8 PC via the USB cable and I push on the Power button for about 10 seconds, I get in the Windows Device Manager in Other Devices a new(unrecognized) device named APX. When I pull out the USB cable the I hear the windows usb disconnect sound and the device disappears.
When I connect the battery, I connect the USB to my PC. I don't push any buttons and after 15 or so seconds I get a message USB device not recognized in the USB controllers section of the Windows Device Manager. When I press and hold the Power button (or Power and volume down buttons), after 10 sec The unrecognized device is moved to the Other Devices section and again is called APX.
I cannot turn it on. I cannon boot into bootloader. I have tried almost any approached listed here an on Google (about 10 different step by step guides) and I remain in this position.
Please help me bring it back to life. Hope it's possible. What should I try. I am fairly technical and can understand most instructions.
Had same problem,the only solution found charging via dock station.My 5 years old child broke usb port trying insert cable.
