MDA will not turn on!

I know i'm being a pain but now my MDA will not turn on, i was following the CID unlokcing thread, downgraded to Wizard Love ROM which went fine, the proceded to flash buttons 1.5 ROM and as usual it hung, went to do a reset to bootloader screen to reflash but it never got there , it doesn't turn on, battery was charged earlier can't have run out already can it?
Any ideas? i've tried to find info to help but can't seam to find any.

I know you've posted elsewhere, but it really helps if you tell us your phone model, if its G3/G4, what the IPL/SPL was before the problem started, etc...
Unfortunately, with the little info you've provided, I can't say for sure what has happened, but on first blush that sure sounds like a brick.
I would suggest you take the battery out of the phone, then press and hold the power button for 10 secs (this should discharge any remaining power) and leave the battery out for 30 minutes (might be excessive, but lets play safe). Don't plug it in and don't do anything else with the phone.
Now, after 30 mins pass, then put the battery back in and plug it into the wall (not your PC, but the wall). Again, don't do anything else. Don't press the power button or anything. If the phone acts like its trying to turn on, then turn it off. Let it sit plugged in to the wall for about 10 minutes. The charge light may or may not come on. If it does come on, then just leave it. If it doesn't come on, then try turning the phone on. If it comes on, then leave it on for 30 mins then turn it off to let it complete the charge.
If none of this works, I suspect you either have a dead battery, or your phone is a brick.

right phone is a G3 is was running the IPL/SPL of whatever buttons ROM has, as i said it hung like it's done a couple of times before when i tried buttons ROM but the other times i've just got into the boot loader menu and re-flashed and away i go, i'll try the battery thing in a fue mins, the battery was showing no signs of going bad was holding charge fine do the batteries just go like that? if it doesn't turn on would i be able to send it back to t-mobile as it's still in warrenty could they fined out it has a custom rom on it i.e is there away to say look at the rom on another peace of equipment to see if original or not, don't know if that makes sence.
grrrrrrrrrrrrrrrr was going to stay with the wisard love rom i kinda liked it, wish i had now
thanks for the info

Just out of curiosity, but why did you go back to the Button ROM? Once you CID Unlocked, you are done with that process. You can flash official 2.x and custom roms to your heart's content and not have to go back to the Button ROM again. Only time you ahve to do CID unlock again is if you do go back to 1.xx IPL/SPL for some reason.
Good luck, I hope that works for you. As for warranty, but doing any custom stuff you void your warranty, but if the phone won't come on at all, then I don't see how they will know (not like they are going to pop a chip out and look to see what's on it).
And no, I wouldn't think the battery would just completely die under normal use. You usually start noticing it can't hold a charge first.
Could be this is a hardware issue, but really hard to say.

i wanted to go back to the button ROM so i could CID unlock my phone, i was having trouble with buttons rom hanging like it did this time and it was sugested that i downgrade to wizard love rom then to buttons rom. I know it voids my warrenty but as u say the phone won't come on at all, oh well i'm doing the battery thing now. think i'll get the battery charger to see if the battery needs charging you never know!

looks like i've bricked it lol

Sounds like it could be the battery, in some cases it will fully discharge (e.g. when shortcircuited) and then can no longer be charged in any regular way. You can try this:

HD2 charge from dead battery questions

I have an HD2 I just bought, should be still under warranty (aside from running wp7 and random warranty-voiding stuff) and I am noticing an issue of when I totally kill it, it seemingly won't charge (or no charge light comes on at least) until I pull the battery out and put it back in. Also, I have noticed it doesn't power on from that state (light goes from orange to green) until I pull out the battery and put it back in. Is it just because I'm running WP7 and hardspl3 or radio 2.14.50... (or whatever recommended radio is for wp7). It's not a huge deal but it makes me curious. Also I get occasional restarts upon booting wp7 but it always boots into it (maybe 1 or 2 restarts every ten boots, and it seems to happen more after total kill). Just wondering if people are having similar issues.
WP7 is pretty cool, but I am wondering how many prefer 6.5? I'm an avid Android user (never ran 6.5 except on a Blackjack ii briefly, and yes, 6.5) and I was curious what you guys thought of wp6.5 vs wp7.
Lastly, I am wanting a magldr compatible sd version of a Desire HD ROM with sense and everything that isn't overclocked (I know there are some out there that are, ie DL.DesireZ 3.x).
Please advise.

It's not WP7, it is MAGLDR. MAGLDR does not have a software in it which allows the phone to charge when off.
My advice to you, never, ever, let your phone lose charge. A dead battery is a dead phone in our case, unless you have spare batteries.

I figured something like that. It's not going to botch the magldr flash though if it dies, is it? I would assume magldr is read-only or close to or something like that to where it can't corrupt itself.

I don't see why a dead battery can kill MAGLDR, it'll just leave your hd2 unable to turn on. However MAGLDR, I assume, isn't incorruptible. Well if you're afraid of corruption from leftover flashing, for whenever you want to flash WP7, Android or winmo, perform a task 29 first, flash MAGLDR, and then the OS. Well if it winmo, then a task 29, then simply flashing winmo and done.
Oh and the reason WP7 kept on rebooting on yours was because your sd card was incompatible. My advice is to reformat the sd card with panasonic formatter, full format btw, and then reinstall WP7. If that doesn't work, you just have to get a new card.
A MAGLDR SD desire hd version I know not of. Since NAND came out, SD development has died off so there are only a few developers that still strive in that forum.

Well it restarts hardly ever so I probably am not going to worry about it. It's the stock HD2 sd that came with the phone. The reason I want an sd build is because I want to dual boot.

I don't understand how I seem to be the only one who can charge in magldr.
I've drained my battery many times to the point where it doesn't turn on to calibrate using Android. Pulled battery, reinserted and connected wall charger. Orange light comes on which means it's picking up charge, leave it for a few minutes so it gets some residual charge in it, pull battery and charger, reinsert, boot up, then during boot process plug the charger back in and away you are, charging from scratch.

I too didnt have any problems charging dead batteries via MAGLDR.
Those who are can update to version 1.13 as its now got a workaround for it apparently.

I wasn't aware v13 was even out. Well it's not a big deal. Glad everyone is having this issue . This bug still beats having to wait 20 minutes for my stock Sammy Vibrant to boot up. Damn ridiculous.
Is your battery life worse on WP7 or WP6.5? I get roughly 8-10 hours. I'm surprised it burns that much electricity seeing as how all it is is some colored squares and no data connection or multitasking.
EDIT: Updated to MAGLDR ver. 1.13 without a hitch. Will see how this goes. For the record I was using 1.12.
I guess this is the fix:
"*Fixed Power-Off-Cable-Plug-Stop. Phone now detects this situation and reboots. Battery controller inside LEO needs runtime control during charge, it implemented in OS."

I could do it on the first version of magldr, as long as the Orange light comes on you're good to go, just leave to get some charge then pull everything reinsert turn on, simple...

I found the trick--MAGLDR V1.13
Plug the phone into a wall charger. Hold the call end button as soon as the phone comes on booting into MAGLDR. Let the phone stay at the MAGLDR menu screen for about 15 to 20 minutes. Restart the phone and leave it on the charger. It will have enough power to make it to the android home screen.

sorry for the delayed reply bro but i justr had this problem lately and know abt the fix for it... just go into magldr by pressing the power key for sumtime on bootup... after that plug in the wall adapter for about 20 - 30 minutes... havng done that remove the battery and insert it agiain w/o the charger... start the phone and let it go the main wp7 screen where it will stay for only about 20 seconds... quickly run to the settings menu and switch on airplane mode and put the brightness to the lowest setting... and quickly lock the screen... the phn will start charging fine... now leave it for an hour to charge and then adjust the brightness as u like and turn on airplane mode... it will work fine... take precautions for next time... there is a kind of an odd fix that was in forums...(sorry dont have the link)... when the wp7 is working go to the default camera and go to the video camera mode and switch back to the still camera and press the windows buttn to go to the main screen... the battery drainage is very less in this case and the stanby increases... cheers!

[Q] HD2 WP7 Mango out of battery keeps rebooting

I don't know if it is the same kind of pb linked to the SD-card, but there is mine:
I have just flashed the Mango with marketplace ROM;worked perfectly! (a bit slow sometime, but nothing really bad). I used it a lot today.
I think I ran out of battery tonight, and now when I plug the phone on power, the phone boots automatically (so stops charging...) and loads to DFT screen few seconds and shuts down (because of the battery?) then charge 1 sec, then turn on, .... etc.
Of course it restarts before the battery charges again after the system loading.
(Question here, does the battery keeps charging when the phone is booting? as the orange charging led is off.)
I might have found a way to stop drain the battery trying to start and stop at the magldr menu... but still don't know if it charges because the led is off.
Any recommendation/advice for me? (To avoid the auto-boot on charging)
(I can't (don't want to) re-flash, because the battery is almost dead!)
Thx
EDIT: I have used the original SD-card of 2GB, I also have a 8GB/Kingston/class4 that I didn't want to format, but if I need I can do it.
It seems that the phone is charging when it is on the magldr menu because the system loading goes much further (but the points animation is very slow when it was very smoothy before, like 1 transition per second)
Still loading after 2min
1. SanDisk 2GB Class2 (Bundled with EU HD2) - could install WP7, card was recognized, after one day of using and installing several apps the system starts to crash, random reboots each 20 minutes or so.
2. Kingston 8GB Class4 (Bought 1 month ago) - WP7 installs but can't get over startup configuration, it stucks, rebootings and Hard Resets won't help (tried a bunch of different ROMs, nothing helps)

seems dead for both cards, but I will try anyway with the second one if I can't boot the system anymore!

After 30 min charging on the magldr menu the phone starts again! Everything seems to be ok, but I am still wondering WHY it is not possible to charge the phone without it to start and try to load windows... Or maybe I missed something...?

I had the exact same problem let phone die... couldnt recharge i just used task29 wiped magldr let phone charge while was off :-\
The reason it wont charge during boot is reason why ur keyboard/mouse dont work and flash on and off during actual booting of windows... dont know what process that is .. but i can only imagine its something from going bios (using those drivers) then going to the operating system (utilizing those drivers) and inbetween doesnt work

I got the same issue. I put it to charge and refrained from entering my pin when it asked to, until the phone got a full charge. Looks all fine now...
Out of topic, may I ask how much storage your phone shows in settings with your Sandisk 2gb card? I also got the same card, and it got only 35 MB total storage and 0MB left. That's right after installation...

Sorry, but I don't know. After booting, it rebooted few times then couldn't find the SD-card anymore, so I formated the SD, took the other and reflash.
Then new one (kingston 8GB class4) is showing 7.22 total / 6.80 available. It has been working great today, and still

The best way to get around this problem if you run your battery dead is:
-Hold both the volume up and down keys while the phone is booting
-It will ask if you want to delete your data, just leave it as is for 10-15 minutes
-Pull the battery and restart your phone
The battery doesn't charge while booting up, so that's why it gets stuck in a boot loop like that.

Hum, just pressing the red button enters the magldr menu, maybe safer than the erase data menu There you can also charge the phone without draining too much.

Yes there is this kind of a problem this is how i solved that!
First of all i rebooted, the device was almost %0 percent of battery.
I just plug it to electricity and close its lcd and wait. I dont know why.. Charging device takes very long time. But it still works. Battery drainage is because of huge LCD, i think the battery drainage caused by the lcd canot be compansated by the charging state, so it keeps rebooting everytime.
When you get you first opportunity, please try turning off the lcd.

unless your charging from a laptop which may only give you 200mA the power from the USB will be more than enough to keep it alive with the screen on. the reason it keeps rebooting is because your sucking the last remaining mA out of the battery, like a sponge, it takes several squeezes to get all the water out, DO NOT keep doing this, or you will need to invest in an external charger or attach some wires directly to the terminals of the battery.....or use a WM HD2!
as others have mentioned, put it in to bootloader(best choice) hold VOL DOWN on restart and theres no chance of deleting data here! or put it in to magldr.
dont leave for any longer than 30min though, get it charging in windows as soon as its got enough to boot, its unclear if the battery full cut off works in the bootloader/magldr

I've been using the Magldr to charge my battery on the occasions when the battery gets too low. Today I managed to wait to long I guess. Even in magldr my phone sits for a minute then reboots itself. I also tried the hard reset screen. I don't have an external charger. Any ideas for me?

I have the same problem when I use my HTC charger. But when I use my Samsung charger (came with my Galaxy Ace) HD2 boots normally. Also I noticed that when I use the phone on HTC charger battery keeps droping. I think it uses more power then the HTC charger charges. With my Samsung charger i dont have this problem.

I tried charging in MAGDLR menu, but that only drained the battery more. (v1.13) I had to buy a universal charger ($4) to get my phone working again.
Any idea why this hasn't been fixed in MAGDLR yet? Or might there be an alternative?
For now, I think I will program Tasker to shutdown the phone at 10% battery...

[Q] HTC HD2 won't turn on<don't recognise Charger or USB

Hi,I have a Android gingerbread 2.3,haspl v.3,MAGLDR113,it's second time my htc block and dont want to restart from the buton,i have remove the battery and it dosnt want to turn on ,there is no screen,the battery was charget,but the red light don't light when i plug the cabel,in my PC dont recognise usb,nothing and the phone,i try for 1 day to remove a battery,but no result,1st time when it happens it work,but for a week i can't use it,Sorry For my English,Some ideas what can i do before i took it back in the store

sounds like it could be a simple flat battery. when magldr is installed you cannot charge the phone unless android is running, so when it is off it does not charge.
if you can try another battery, or your battery in a winmo hd2, that will tell you if its teh battery.
If you have a spare usb cable (any type, doesnt have to be a hd2 micro usb cable) cut end off, bare red and black, hold red to + and black to - on teh battery for about a minute, which should give it enough power to charge.
Also check very carefully that you dont have a bent battery pin from all teh battery in/out. they bend easily.

i hava a Bat charger and charge the bat all night,and the morning it show me that bat is charget,put it on the phone,but nothing ... cant turn on

Maybe battery is dead. Do you own a volt meter an can check the voltage provided by the battery? It shoud show up about 4 volt.

i took the bat to my friend with devace to check the battery,and everything is OK,but the phone didn't turn on,Can i reinstal the Android ?and how can i do it

Is there a program that can connect to the phone and erase everything

To wipe the phone install the HD2 toolkit, you can download it here.
It includes every tool needed for maintaining your HD2.
Be sure to install the drivers!
Start the program and press the Task29 button, follow the instructions provided. When it's finished your HD2 will be fully wiped, so you would need to reinstall everything.
Do so by doing a MAGLDR repartition. After that choose MAGLDR update recovery to flash the Clockworkmod recovery.
Then go into the Clockworkmod recovery and flash your rom.
Now your HD2 should be fully wiped
BUT! If your PC doesn't even recognize your HD2, and you can't even get to the bootloader screen by pressing and holding both volume down and the "end call" button. Then it's probably a hardware failure.

Magldr repartition flashes cwm so no need for the update recovery step. That's for, well the clue is in the name,,, updating the cwm version on an already partitioned instal.

Okay, thanks for clarifying that!
Didn't know it worked like that, I only use CLK.

Electrical surge, perhaps? Overheated circuits? Who knows.

Somehow the phone start,I have put on my router,and plug in USB all night,in the morning i remove a battery,remove a SDcard put back batery,plug usb and it go,I replace infromation from the card with onother sdcard,flash the phone. 10x for the help,maybe now everything is ok

- the screen freeze on image and not respond on touch neiter button
-after 2-3 minutes phone temperature became very hot and screen again on freeze
- removed battery (for power off button not responding)
- insert battery
- no power up, no green LED with AV adaptet, no USB recognized
I'll trying to charge battery but i don't have a table battery chager.

Could you please repeat me what you did, since I didn't get the first part, what did you put on your router (what kind of router please)?
I've tried using my phone with another HD2 phone's battery which is working (and which also started with my own battery?!) but my own phone wouldn't start at all with the other battery...
The battery wasn't fully charged, but did it have to be, if so how long should I charge the battery with the cut USB cable for it to be charged enough please?!
TIA
P.S. I've tried a voltmeter on my battery and it said 4.14V (should it be 4V exactly?) and should I even try the cut USB charge trick again (since I've tried another phone's working battery)?

Could you please repeat me what you did, since I didn't get the first part, what did you put on your router (what kind of router please)?
I've tried using my phone with another HD2 phone's battery which is working (and which also started with my own battery?!) but my own phone wouldn't start at all with the other battery...

Ok if I understand you correctly you have tried your battery in a working HD2 and it worked. Then you tried the battery from the working HD2 in your device but your device still did not boot up. If this is correct I do not feel your battery is the problem, but still check the battery pins on your device to make sure none of them are not slightly bent and not making contact properly.
Also if you can provide more info on what you may have done to cause this or what happened when your device reached the state it is currently in. This info can help others and me help you better.

I have a similar problem.
The phone won't start, it gets to the white htc screen sometimes but quits within a fraction of a second.
This has been so since the first Android boot hung (I suspect I have not followed the steps accurately enough...). I have charged, decharged and recharged the battery using the suggested USB-cable technique, but this was of no aid so far, so it's not the battery. Pins and all's fine.
It's someone else's phone, too, so it would be rather unfortunate if I bricked it.
Are there any other common reasons for this behavior? Most tutorials rely on a PC connection, but as it does not recognize such a thing, that's a bit of a problem.

Finally the same problem here.
Battery status was about 70% and running smoothly (WinMO Custom Rom) since installed.Unlocked the Screen and tried to start programs.
The Icons were lightened up but nothing happened.Tried to softrestart...Nothing happened.
Removed and reinserted the Battery.
=> Not turning on.
-another fully charged Battery => nothing
-charging on Charger => nothing not even charging light
-plugged into (running) pc => nothing not even charging light
-5 hours in the fridge => nothing
-charging over night => nothing
Any hints ?
Thx for the goot work around here and greets from Germany !

PS If anyone got one to offer => contact me. Dont like those situations

Bad news!
Seems like your MB is gone...:crying:
Maybe one chance left for a JTAG attempt to a local service shop...

thats what i was afraid of
at least it happend only one hour after i made a backup
thx for the reply !

stuck in bootloop. cannot get past magdlr

I didnt charge my phone for awhile. I recently plugged it back in and now I cant get past magdlr. After the 12345 GOGOGO it restarts endlessly. I can enter the magdlr bootmenu but cannot enter AD recovery. I heard magdlr doesnt allow charging when android isn't booted which is absolutely retarded. I dont have access to another phone to charge the battery or an external charger. Id prefer not to cut off any of my usb cables either. Are there any other solutions?
Or is the battery dead? I check the pins and they all look alright.

You could try to switch to clk but you will have to do it quickly in order to have some battery left and it's risky since it could interrupt the flashing etc.
Or you wait some time and retry after some hours and plug it on when you try next time.

Hey mate, the best bet for you now is to flash a WM ROM. If you already have one in your PC, then you are in good shape to recover your HD2. If not, i suggest you download a suitable one(preferably stock) real quick.I hope your battery level is at least at 40%. Anyway, even if your battery is dead, all is not over. Just find someone with a HD2 or concoct some bull**** to tell your local smartphone repair dealer and get your batt charged. Dont worry,your HD2 will definitely breathe again and you can run Android in it again.All the best
Cheers

Not true. When put in charging the HD2 starts.

You need to go back to stock or install clk. The 50% battery is not a must when flashing. Clk will charge your phone when turned off. Magldr will not. You need to do something quickly to get your battery charged, then you can decide on a from or something else.

could be simply not enough charge to start booting, since there is a large current draw after magldr boots,,,id give the bare wire usb lead a try before reflashing, , if you have a spare usb cable you dont mind destroying. cut the end off, (any uab cable, deosnt have to be for this phone, standard, mini, micro, doesnt matter, ) bare teh red and black and hold red to + and black to - on teh battery for about a minute, , should have enough power to get into booting, and charging starts about halfway through booting.
(course, it might not be that problem, but if you have a spare cable it cant hurt to try)

true, and since you're so full of criticism, how come YOU dint hack a winmo device to load up a custom bootloader into the space where a splashscreen goes to allow all kinds of things to be done to the hd2 , ****ing retard. Hope its bricked.

First, install CLK or flash a WM ROM. Then you can do a full clean installation of Task 29 onwards, including reflashing Magldr. And son, you cannot expect all features to be integrated into Magldr. Most probably, a simple reflash of Magldr should solve your problem, but for now, get your batt charged.

your first part of your post is helpful mate...but lets not start a keyboard fight here...chill...

Or just go into the bootloader (tricolor) and stay there and charge the battery from there. no need to boot into Android

lol, and the years old argument 'does it charge when in bootloader?' resurfaces once more,,,

yes, it does

no, it doesn't, and so it goes on. Hehe.
(Not that I expect to convince you, of course, you've been around near on 3 yrs or so, so you've seen the numerous "yes it does no it doesn't mine does bet it doesn't your wrong no I'm not" threads about this, , but consider this,,, if it were really that simple, would we not have a deffinitive answer by now?

well, i guess you have to try it, then you will be convinced i wouldnt post it if i did not try that procedure before it takes a little longer to charge due to the display. its on during charge. I mean guy has nothing to lose, for me this works.

hehe, i DID try it, lots of people have, and the outcome? some say it does, some say it doesn't.
My own theory is that it does allow some residual charge to build up, by warming the battery if nothing else, making it seem that a flat battery is no longer flat, in the same way that leaving any almost-flat battery for a while,warming it in your hands and such, makes it work a little more, but from the test i ran (admittedly about two years ago), i started with 10% power and left it two hours, when i booted winmo it read 8%.
But as i said, i don't have any delusions that i will convince you (or anyone else, for that matter), its one of those questions that are best left to the individual to try it out.

hmm i know you are one of the guys, whose know what they talk about. It really seems, that for some it works and for some not.
Yesterday i tested it that way:
battery was at 63%, booted into bootloader, waited 45mins, unplugged the cable, and booted into android (cable still unplugged), battery at 74%.
A bit strange, if the heat would add 11% of charge to the battery. But hey, its HD2, never say never and everything is possible (well not really) D
i will test it once again now.. conditions: 75%, connected via usb to pc, not to the charger. I give it 2h. (poor display :/)
after 2 hours of charging in bootloader, my battery is 98% charged. I guess i am one of the lucky guys

@greg17477
With standard charger, works for me too. Maybe if you have an inappropriate charger and display drain all charging current did not work.

hmm interesting, if a water pipe hadn't just burst this morning (i'm on a break, covered in wet plaster and sawdust) id retest it myself, , perhaps i tried it in the pc or something.
I shall certainly start advising people to give it a go from here on out.

well i stand corrected. just shows how things you take for granted aren't always so.

respect, you have some balls
btw. as long as it doesnt hurt our hd2, people can try this method. nothing to lose there.
