[SOLVED!!] Looping Bootloader or startup and unable to charge to reflash

I really don't know what's just happened...I think maybe my TP2 just decided to die on me.
I was using NRGZ Leo ROM from 22nd Feb. All was going well until my battery ran out today. At the time, my daughter was playing a game on it, not from WM, but from the Android port (Haret). While she was playing, I heard the familiar short vibrate of a soft reset. I know my battery was low and I suspect the battery wasn't charging, although it was plugged in (not sure if Android supports charging yet in the later builds)
Anyway, for some reason, it wouldn't go past the vibrate/Touch Pro2 screen. It just kept resetting and looping back. I attempted to do a hardware reset (power button, talk/send, end buttons) but accidently chose the wrong combo (power button, volume down) and entered bootloader. No problem yet, just reset and try again, right? Only I didn't get the chance, as it reset itself and looped through bootloader.
Now I am stuck in this loop. I can't flash from SD as it wont stay on long enough before self-resetting to find the RHODIMG.nbh on the card. I can't connect to my PC as it wont stay in bootloader long enough before self-resetting for my PC to install the "Windows Mobile Device" drivers, and even if it did, when it self-resets, it would disconnect anyway. I can't connect to MTTY for the same reason. I can't connect to ActiveSync or WMDC as I can't boot to WM to get ActiveSync running on the device.
When plugged in to AC power or through USB, it fires itself up automatically and into this loop, and it wont turn off manually, reset or accept any other button combos to enter RUU (from SD method) or to do hard reset. When it is not plugged in to any power source it won't even switch on.
I suspect it is resetting as it is not charging. I'm guessing that when in bootloader, charging is disabled, and I think this because I was originally getting 3 seconds of bootloader, now I am getting around 8 seconds, but it doesn't get any better than that, and I don't know of a rom upgrade method that can be done in 8 seconds! There are a few seconds of charging time before bootloader kicks in and the orange LED goes out and presumably stops charging. Am I right in thinking there is no charging in bootloader and in the Android port (I am using the latest version from 27/2, rhod100).
Basically, to summarise, I am stuck in bootloader-reset-bootloader loop, I cannot connect to pc in any way, flash from SD, Hard Reset, I have very little or no battery and it won't charge because it keeps going into bootloader where there is no charging taking place and it wont turn off to charge that way either.
Any help will be greatly appreciated. I don't hold out much hope though. At the moment, it doesn't seem that I am able to interact with it at all to make it do anything different or to manipulate what it is trying to do. Hopefully someone will see something familiar and maybe have some suggestions.
Oh, and by the way, it's nothing to do with a bad flash. I've been doing this for long enough to know what I'm doing, and I wasn't even doing a rom upgrade at the time. My last rom upgrade was 2 days ago and all went well, and I have been using it without problems since, until now. I haven't flashed my Radio or SPL since HSPL was released, so I know it has nothing to do with that either.
Thanks in advance for anyone who can give any advice at all, or even just take pitty on me! Apologies for all the text. I know it looks boring and may put some people off reading, but I needed to get all the info in.

Are you able to charge when it completely turned off?

can you pull the battery out, put it back in and simply charge for an hour or so to get some juice into the battery?
Then you could maybe reflash it from the bootloader or sd card...

I can't get it to turn off, power button has no effect.

If I take the battery out, obviously, it cuts the power and the looping stops...until I put the battery back in, and it starts itself again. I can't stop the loop and I can't turn the power off or even stop it switching itself on.

I had exactly that problem after a bad romflash. I bought a decktop cradle for the tp 2 that has 2nd. battery charger. Charged the battery and reflash, everything was ok again.
So, juice up the battery and do a hard reset or reflash..
SOMETHING LIKE THIS

I know you prob dont wanna hear it, but id say its a warranty job. Theyll just force flash it anyway so they wont notice the rom you were using.

Cheers guys. I thought it might be the rom. Not sure how though as like I said, my last rom flash was a couple of days ago and it was fine. Guess these things just happen sometimes. I'll try and get the battery charged somehow. Trouble is, I don't know another single person who has a TP2, so it looks like the cradle option I think. It did cross my mind to be honest when I was trying to think of alternative charging methods.
As for the warranty idea, if it can be avoided, I'd rather not take that route if I can help it, but thanks for the suggestion. Lets just say that will remain an option as my last resort if all else fails.
Still open to suggestions if anyone knows of any miracles....any Hogwarts graduates kicking about these forums with a few magic words to spare?

Hey man, I had the same issue when my phone wouldn't for some unknown reason charge.
1) Take our your battery
2) Plug in your DESKTOP CHARGER (not USB from PC!!) to microUSB slot
3) Put your battery back
4) Wait few moments (5 minutes)
5) and you are ready to boot, now you can even charge from USB. No idea why, but looks like booting takes more than 500mA :O
If it wont help, swap those 2 and 3 points

Hey guys! Please give this thread a better title. More related to the problem. Sounds like it could be useful in the future for hopefully very few people.

OK, I will change the thread title. I searched for quite a while but couldn't find any similar cases. But it seems it is more common than I thought since I raised the issue, so a new, more specific title might be more beneficial to other users experiencing similar problems.
For the record, I haven't solved it yet. Waiting on a standalone battery charger I bought from eBay. Didn't really want the cradle. THIS is the one I have bought. I will update on my progress when it arrives.
Thanks for your help to all who have contributed so far.

Hi I have the same problem the phone won't charge or connect via usb I think it is a faulty usb port the phone have & because of that it is causing the phone to go to bootloader.

I've had this happen before, just plug it into the mains charger (wall charger) and let it sit for a while. It will loop a couple times but once there is enough juice in the battery it will be back to normal.
Since you have RHODIMG.nbh on your sd card, maybe taking your sd card out would help it a bit.
There have been other posts with the same issue and plugging it into mains will solve the problem

Not true. just the battery is really low, once charged enough to power device after boot, everything will be back to normal.

Seems like it would make sense. I don't have my wall charger on me now...does the Rhodium not boot up without a battery in it? I thought my old Hermes did, guess I've never tried it with the TP2.

This might sound a little stupid, but I actually know somebody that said it worked for his iPhone (waste of 3-4 mins if not). Plug in the USB charger from PC. Reboot the PC without disconnecting the phone. Wait 3-4 minutes...

Definitely doesn't power up plugged in without a battery. Battery needs to be present. Still waiting on this charger though. I'm hoping it's not one of those where it says the item location is Cardiff (UK) when actually it's in Hong Kong and takes 14 years to arrive

I really don't think it's the mini usb port as it charges and tries to connect to pc before bootloader kicks in & it all stops.

Hi I found a way 2 get past the bootloader loop just plug your headphones went in bootloader and restarted the phone but it still won't charge or sync with computer.

Well when I unplug the ac adapter, mine doesn't last on bootloader for more than a couple of seconds before dying. Doesn't even get to the RHODIMG.nbh update screen that way - not enough charge (I'm still hoping). Tried charging overnight while looping but still wouldn't charge enough. The trouble is that obviously the bootloader is killing the battery as it's not charging very much.
Got my charger finally....but they sent the wrong one. Waiting on a response from the seller. The "dock" on the charger wasn't big enough, so while the connectors were in the right place to charge the battery, the battery didn't sit flush, so they wouldn't reach the points on the battery itself. Hope they have a TP2 one & it's not just them thinking it's compatible, as it's the only one on the whole of ebay UK that has them in stock in the UK. Don't want to have to wait up to 2 weeks for one from HK.
I will keep you posted anyway.

Hi I brought mine 2 get fix because my warrenty got void due 2 water damage. I think it is the usb port that is causing this, saw in other forums the same thing. Will get back the phone on monday & I will update u on the situation.

Dead phone, help!

Well first it seems my phone is not able to charge anymore... (Not even with the .bat file it just loses power when I try that)
Some times it manages to retain some charge but it goes away really fast when the screen is on.
I have no time to flash the device due to the low battery and super fast battery drain.
The sd seems to fail randomly, some times it is recognized, some it is not.
When you plug the phone to the usb in a pc a message USB device could not be recognizes appears some times (not always).
Blinking red light some times, never goes to green, eventually goes to solid red but doesn't charge enough to flash it.
Could the battery problem be software based? Actually it has no OS, Andriod flashed, no boot and only recovery is cloclwork latest version.
Any suggestions here? Everything is appreciated since it may be dead... I want to test anything and well tell you what happened, at least use it for science =P

Go into recovery and charge from the mains with the original charger.

I'm trying to charge it and now using the .bat method but it won't go over 3565mV which is not enough to flash it. =S Dunno if letting it connected charges even if there is no notification at all.
And I've tried that and after turning it on and checking it never goes above 3.5 and I read I needed at least 3.68, what can I do? reset battery stats? or something else? Can I charge the battery directly? like with some cables?

And also, the red led doesn't turn on. If I plug it toa pc it sounds like an usb is connected, but no led light. What can I do then?

I had the exact same prob. Change the USB Cable and/or the PC u are using. Mine was stuck at 3588mV. The cable of the SGS2 did the trick for me. It was my friend's!

That's an interesting option I'm gonna try it, but I think it may not work because I tried to charge it at work with 3 different cables and chargers and no luck still. Buy maybe it was just the fact that between the time I charged it at work and got home it discharged, I'm trying this tonight and tell you what happens.

No luck still, stuck at 3557mV and won't let me flash it.
Sometimes the phone even freezes in fastboot after some command tried.
How can I charge it then?

[Q] Need help

So I'm currently using the Suarom ROM, and for the most part it's been working fine. Suddenly I have a problem. Last night I plug my phone in to charge and suddenly it won't charge. I tried with two separate chargers.
It's still a new phone, so I can bring it in for warranty work. I just want to make sure I take all the steps necessary to "un void" the warranty. I'm a Rogers customer. If anyone can help I'd appreciate it.

Theres a thread in the DEV section that provides instructions of how to completely un-root and restore your device to factory before you turn it in for services.

The only problem is, my battery is at ten percent with no way to charge. The strange thing is that when I plug the phone in, the charging symbol appears. Just doesn't charge. Any idea why that would be ?

Tried different chargers? maybe plug it up to your PC see if you can get some juice that way? i can see the cable/charger going bad before the usb port on the phone ( but **** happens ) 10 percent should be good enough to get your phone back to stock though, i did it at 7 percent not to long ago, you just cant play around you have to click and run and get it done so it does not die. then if it dies after at least you are stock and can just turn it back in. but to be honest for a charger problem i VERY SERIOUSLY doubt they will be looking at Software and roms. thast a defect, and i think they will just do a clean swap----JUST LET IT DIE so they can not turn it back on in the store..lol

Ya could have a derpy battery and the phones fine.

Yeah, I have tried three chargers with no luck. Haven't tried a PC yet but will after work.
So if I'm getting the lightning bolt charging symbol, odds are it'llbe the battery rather than the port?

take it to best buy or an at&t store....and just say, hey i think i may have a bad battery do you have one i can use to see if my phone will power on and recognize the charger after it is plugged in. then you will know, unless you have an extra battery just laying around.

I had a similar problem like this before. Try charging with the phone off.
OR
If you want to troubleshoot and isolate the problem, try getting an external battery charger and a spare battery.
If you charge your stock battery and it charges with the external charger, your phone may be the problem. If not, then it's the stock battery.
And with the spare battery, try charging it via phone charger.
These are the possible ways I can think of at the moment. Hope this helps!

[Q] Fried battery?

So occasionally if I'm up too late, I don't hear my alarm (on phone). Well, I had noticed recently it got super warm to the touch if I overslept a bit, I think because it just buzzes constantly while plugged into the wall.
Anyway, it won't turn out now without direct power plugged in. Tried reformatting, wiping cache, everything.. I can get it plugged into the pc and booted up but as soon as I try to select media storage, it fails. Won't turn back on now even with it plugged in.
Any suggestions, did my battery just croak?
TYIA.

For real? Man, I'll be honest.. I had to break my flashing addiction, so I intentionally got an older Nex, so I could root, and leave it the F alone.. Haven't flashed a ROM since I owned it (bought it unlocked like 12 months ago), couldn't even tell you what ROM is/was on it..
Since when is it a bad thing to charge overnight? I adopted that habit when I went android. :/

well some phones don't have any problems with ovecharging but its not recommended nevertheless
heard some batteries were F***** up from overchargind

Same exact thing happened to me...thought the phone was fried. I replaced the battery as a last ditch effort and she lit up like a Christmas tree. And as for that last response, I leave mine on the charger all night literally every night without any negative issues. You cannot overcharge the battery on an android phone. They have protective charging circuits, just like laptops.

I'm hoping it's only that but wouldn't it fire up with wall charge? It freeze on the Google loading screen.. have a feeling it's cause I wiped it and maybe it didn't finish.
EDIT: Okay, I obviously was a bit messed up earlier.. I factory wiped it, including the OS.. how can I jump an OS onto this thing if it won't boot without charge?

Okay, well the symptoms sound exactly the same as when I fried my battery. At first, mine would only boot with a wall charge, but then it stopped doing even that. The only thing I could get into was the boot loader. I'd try a new battery before worrying too much. In the meantime, however, can you see if the phone is being recognized by a Windows PC, or if you can get the bootloader?If it is bricked, there is a bit of software called OMAPFlash that i used once that can completely reset the phone's programming.

If you just wiped the OS from recovery you should still be able to boot into fastboot. Are you able to boot into fastboot (power+volume up+volume down)? If so then it is not hard to fix.
If you can't boot into fastboot, try:
1) Without battery, plugged into wall (try a different charger)
2) Without battery, plugged into computer
3) With a different USB cable.
Does it vibrate when turning on? And does it go into fastboot?

When I plug it in, the initial charging indicator comes up (Battery with lightning bolt), but won't otherwise turn on via holding power.. or get into fastboot at all. If I plug it into my pc, it initially shows the power indicator again but same deal. Interestingly enough tho, my pc makes the sounds it makes when it's syncing or installing usb drivers for something.. except it starts, then stops, then continues.. it's non-stop trying to sync but nothing is happening, it's almost as if it's getting either a partial charge/connection and then it stops. What I thought before was a battery I'm thinking is worse cause I can't get the thing on at all now. :/ Might be time to hit Verizon today..

It was the battery but now I have no OS on the phone.. UGH. I can't get it into storage mode to pull a new ROM over from PC to flash. Anyone know how to force a ROM over via adb?

[Q] Stock OneX switched itself off, now red flashing light.

I have used the search button and found many people with similar problems but I don't think any of them are the same as mine hence the question.
Please be patient with me as I'm new. :good:
My 18 month old factory stock OneX was switched off and on charge over night and in the morning the green light was on.
I took the phone off charge and switched it on, all was fine and I put it in my pocket and drove to work.
After about 5 mins I hear the low battery chime from the phone and when I take it from my pocket it has switched off and will not switch back on. I plug it in to a charger and get a red flashing light. I've searched for days and tried all the button pressing tricks, charging from mains, charging from usb and nothing has brought it back to life.
Thinking the battery had just decided it no longer wanted to be part of this world I bought a OneX+ battery and changed it over, it is still the same.
If I hold down the volume - and power buttons it will boot to the screen where it tells you it is ***locked*** and tell me not enough power to flash.
If I plug it in to the pc the HTC MTP device loads every few seconds.
Is my phone now an expensive paperweight or can it still be revived? Any help greatly appreciated.

What I understand you can go in bootloader this is ok! But it is strange that HTC MTP device loads every few seconds. Are you able to start the Android? Becouse only if you start the system you can see the MTP device in bootloader it is inposible.
Second download this unzip to folder and start the file chargeONEX.bat report back if the battery start charge. Dont worry the phone will start a lot of restart in the bootloader but will slowly charge.

I can only get in to the bootloader when connected to the mains charger, it will not go in to bootloader when connected to the laptop usb port.
I will try on a desktop pc and see what that does.
I ran the .bat file and it gave me a voltage of 477mV, this is a brand new OneX+ battery, I did try this script before I changed the battery and the old one was 536mV
Because the phone will not boot in to bootloader when plugged in to the laptop it only runs once, then the screen goes black, it is then that the MTP device loads every few seconds.

Thank you very much for you help. :good:

I then have to select Fastboot before the script will see the phone and the voltage was 501mV, it then goes black and the MTP driver tries to load again and again.
Any idea what could have caused this in the first place and why a new battery is doing the same?

Just you buy your new battery empty this is bad luck for you.
in my zip have fastboot-mac rename it to fastboot and the fastboot rename to fastboot-windows. Are you manage to start in bootloader. Are you with custom recovery. If you are with custom recovery go in recovery and try to charge the phone in recovery.
EDIT: I see you are full stock will not help with charge in recovery.
The best way will be if you start the script to charege the phone but if you cant the best way will be to charge the battery manually.

Checked again and the voltage is now 550mV.
At this rate it will take weeks to reach enough charge to switch on.
I'm not sure it will ever get to full charge, I think something else on the phone is causing the issue.

Wait to be possible to go in bootloader without charger and when you go in bootloader run the script to charge.

As my other thread has now been closed does anyone know if a lithium ion battery WILL actually recover from this voltage?

i think not, the system reads the battery voltage and 3680 mV is round about 10% of charge so 550 is way undervolted. and if i am not mistaken 4200 is about full loaded.
edit :
at least that's what i read from here

I am not sure the battery is deep discharged but have 50-50% to be good. If you have battery pack but not to connect with usb to the phone The battery pack must use the pins on the back side on your phone try to wake up the battery or manualy disconnect the battery and charge it or the chipest way is to buy new battery but mesure beffore to buy.

The battery voltage is slowly rising and is now at 562mV.
I'm still not sure this reading is correct because when you start in to fastboot or recovery you can remove the charger and the phone continues to run. Surely the phone would switch off as soon as the charger was removed if the battery was as low as .5V
Any ideas?

well it may be a bit more difficult but i would look for a way to charge the battery from another source outside the phone. something like a little project of cutting wires and connect them straight to the end of the usb cable (wall charger) ...... welll something like that ?

I'll give it a go, nothing to loose.
This is a new battery I've got in the phone now, the original one read the same voltage. Only thing I didn't do was to check the voltage of the new battery before I installed it.
I'll try charging the original battery that is sat on my desk.

yeah if you can get that one to full load and the phone reads wrong its other hardware i'm afraid

I've just checked the voltage of the orignal battery that I removed from the phone fully charged and it reads 4.2V, my multi meter might not be 100% acurate as it's only a cheap one. I also checked my 65% charge HTC Desire battery and that reads 3.9V.
So it looks like the batteries are fine and the phone is seeing the wrong voltage.
Do you think this would definitely be a hardware issue?

I cant say no but indeed those voltages looks fine. It could be the circuit on the mainboard not reading correct
