[Q] stuck on NRG boot screen and cycling - HD2 Android Q&A, Help & Troubleshooting and Genera

stock tmous hd2
flashed .12 radio rom
formatted sd card
installed energy 21683 sense 2.5 cookie (not the 2.0 version)
ran fine.
copied mdeejay v2.3 evosense revolution as follows to root on SD card
- android\(lots of files
- data_512\img
- data_1024\img
inserted sd card, powered up, file commander, ran clrcad.exe, then haret.exe
got to htc boot screen. took what felt like longer than it should. pulled the battery (doh!)
reinserted battery and phone was unresponsive.
tried to do hard reset, nothing
plug in usb cable and now phone boots to NRG boot screen shows R,G,D text at bottom, shuts down and then restarts the cycle. It never moves past boot screen and keeps cycling.
W/ usb cable plugged in I was able to do hard reset. didn't help.
W/ usb cable plugged in I was able to get to boot loader screen, ran NRG installer.exe and reinstalled NRG. (installer seemed to think everything went fine) still didn't help.
So my phone is now stuck, won't power on w/o usb cable and when I plug in usb cable, it cycles between boot screen and off.
help. tia

Have you tried taking out your SD-card, then doing a hard reset?
Have you tried backing up the things you created (don't worry about things that other programs like Android created) on your SD-card, then reformatting it? Then restoring the stuff you backed up, and re-doing the Android install?

thanks for response.
hard reset w/ sd card in and out. no difference.
formatted sd card.
can reinstall android files on it but seems pointless since i can't get to winmo to run them. can't get past winmo boot screen.
thinking i should try going to bootloader screen then reflash stock tmous rom? if that works can always come back the other way? thoughts?

You could run a Task29 -- a utility that clears your ROM and flashes a "blank" ROM. This is one of the remedies for unusual behavior. After Task29, reflash your custom ROM.
Otherwise, yes, you could try reflashing a stock ROM. If that still fails, then I would call this a brick/"hardware issue".
Good luck!

yep. it's bricked. unless anyone else has better idea.
task29 back to NRG didn't work
flash to stock rom downloaded from Tmo website didn't work either. (now it dies at the tmo pink stick together screen just after showing the R,G,B text. and begins the cycle.)
this is so sad. I need to figure out what i did otherwise not likely to pick up another hd2. figured it was cheaper way to get decent hardware (save 100$ or more right now on craigslist over galaxyS.) and have option to play w/ winphone7.
does android normally take a long time to boot on first try? if i wasn't after the apps and google integration, i might have been happy w/ nrg rom. it looked sharp and seemed to run quick for the little time i played w/ it.
sucks i gave my wife my galaxy s (w/o a dataplan on her line) so she could have nice phone for texting/pics/vid/facebook etc while at home through wifi. now i've got to renig on that gift or get her to trust me w/ another phone!!!
just sucks all the way around. darnit!

Here's another idea (this actually happened to someone before):
Look at the battery contacts (the pins) shooting out of the phone when the battery is not inserted. Are they bent in any way? If they are, bend them gently back into place so that they are completely straight. The pins are delicate, and since you took off your battery, there's a possibility you accidentally bent them. This would lead to random shut-downs/resets.
It might be crazy enough to be the problem you have...
But you know, you could get the HD2 replaced for free, as long as you are under T-Mo's 1-yr warranty -- claim a hardware defect that couldn't be solved by the upgrade ROM. At least it's free!

Hallellujah!!! Stupid pins on the battery!!!!! THIS SHOULD BE a footnote for the newbies in the flashing sticky!
Thanks for the awesome advice!!!! I'm so glad that was the problem.

hi MATE,
The main problem is in Android folder
i'd suggest you to get the Build that asks you to copy n paste all files of Android folder to ur SD Root, that way u'll have all files on ur sd card.
2nd now wen ever you want to boot ur android of WWE all you got to do is DELETE ANDROID folder thats located on ur SD card, I had same issue as you because i test roms and i love messing with them.
3rd: You dont need to hard reset or soft reset if you needed to reboot ur Android (once its running) all you need is hold Power off button u'll get the reboot option as u select the reboot it will show you few rebot options there you gotta choose HOT Reboot that will restart the ANDROID only and that way you u can save ur self from going thur long painful process and yet stay in android os.
PS: i am currently testing the build that asks where i have all file inside ANDROID files and image @ my SD Root, i have same issue with this one but lets see if we could figure out the real culprit.
Hope this help, Feel free to share your experiences

The OP's problem was that he took out his battery while Android was loading, and when he put back the battery, his phone could not boot into WM.
I guess my last thought was correct -- the battery pins were accidentally bent while the OP took out the battery.

[Q] Help!

Hey guys,
Sorry to be a burden but I'm having a few issues with my hd2, and being a noob I didn't really know where to turn except this forum.
Basically my dad bought the hd2 from the UAE early this year and it all worked fine on stock settings for about 6 months. In the last few months, however, the phone started to lock up, and it got to the point where it wouldn't even boot properly.
In an effort to fix the problem I went with a hard factory restore, however, this seems to have caused more problems as now the phone is stuck in the bootloader.
I've been searching for hours, and have come to the conclusion that I need to update the flash? and then possibly install a new rom on the phone?
My major issue in doing this though, is that I can't seem to connect to activesync while the phone is in the bootloader.
Please help me sort this out.
First of all lets make sure that your trying perform the hard reset correctly.......
You need to hold down both volume buttons whilst the phone is turned off..... Then tap the power button and keep the buttons held down.......
Release them when you see the confirmation screen.........
Powering on while holding only the vol down button will take you to bootloader....
If you need to reflash the device then have a read of this thread here....
If its a "Tmous" HD2 (green and red call/hangup buttons) then you need to read this one
When connecting to the pc in bootloader you should see the word "serial" at the bottom of the screen change to "USB".......
Might be worth checking the text on you bootloader screen for any irregular looking characters, there have a few cases of people with corrupt bootloaders, usually these will display odd looking characters at the top. This is quite rare though.
If you want to flash another stock rom then you wont need to worry about HSPL just download the appropriate ROM and follow the instructions on screen.
Start off at the HTC site and input your serial number to see which ROM is suitable for your device.....
If none of that helps then hold out for some advice here from someone with better knowledge of these things.....
Ok well I've just tried to do the hard reset in the way you've described and had no response from the phone. I had to remove the battery from the back to actually power down the thing as nothing else seemed to work. I can't actually seem to start it up again now =S
Thanks for all the info, I'll keep trying to get it started. I'm downloading the stock rom from the htc site. Hopefully I will find a way to install that.
Also, when the bootloader was up, there weren't any odd characters that I could see. It all seemed pretty standard. It had the current rom driver which was 1.42 or something and a few other lines of info.
Thanks for the post.
edit: perhaps the battery is dead?
No problem.
Is it charging when plugged in and turned off?
If so let it charge while turned off for a while and then try to boot........
If you cant get to bootloader and establish a USB connection then you could try flashing the ROM from the SD card.
rename the rom to "LEOIMG.nbh" place it on the root of a freshly formatted (fat32) sd card and turn on the phone holding vol down..

To be honest I have no idea if it is charging whilst turned off =S All I get is the bootloader when it decided to turn on and that gives no indication of power level so I really have no idea. It makes updating a rom pretty scary haha.
So I just attempted to install the default rom from teh htc site, but failed due to the lack of activesync. It was strange though because the updater managed to change the screen on the phone and get to 1%. It then crashed and I had to go through this recovery process.
I will have to try this SD card process I guess. Could you perhaps link me to a more in depth guide to how to do this?
Thanks a lot for your help I really appreciate it.
you should get a red light up near the earpiece to indicate that its charging........
try this video for flashing from sd card......
I am not getting a red light flashing? But it doesn't seem to be running out of charge. I'm still having lots of trouble
It would seem that I need to install this hspl before I do anything, however, I can't install that if I can only access the bootloader screen. Does this mean my phone is bricked?
I want to be able to set up a rom straight from SD, however, I have no idea where to start. That video just seems to send me in a big loop.
Perhaps you could link me to a simple rom that I can attempt to load via sd card?
edit:
I seem to have somehow fluked an install of HSPL 8G XE.
I have no idea how this happened or whether it is good or bad.. but at least something has happened.
Hmmm
installing hspl is covered here
as long as the word "serial" is changing to "USB" on the bootloader screen when you connect to the computer you should be ok.......
You dont need HSPL to flash via sd card but I think that video was directed more towards people installing cooked ROMS from XDA.
Installing a stock rom will automatically overwrite HSPL so unless your planning to flash a custom ROM then installing HSPL is pointless........
You might be better off installing a cooked rom. (Artemis, Dutty's)
They tend to run better than stock, if you get one running then it will be easier to get back to a stock rom (if you want to) than the situation your in now.....
This is from the flashing guide;
Flashing Via MicroSD Card
NOTE (PLEASE READ): If you flash a Stock Rom via microSD Card then it will overwrite your HardSPL with a stock SPL included in the nbh file. This does not apply to custom roms as they do not include an SPL. BE CAREFUL!!
1. Make sure your microSD is Formatted to fat32 (you dont have to delete all files but it is safer if you do)
2. Download your prefered Rom from the LEO Rom Develpoment Page and unzip/unrar it to your PC
3. Goto the Roms Folder and rename the .nbh file to LEOIMG.nbh
4. Copy the LEOIMG.nbh file to the root of your MicroSD Card
5. Plug the MicroSD Card into the phone
6. Reset the device while pressing the volume down button to enter the BootLoader screen, you will first see a tri-color screen with the phone and SPL Information at the top
7. Follow the On Screen instructions to start the update
8. After flash has completed, press the reset button with the stylus to reset the device.
Reckon you could link me to one of those roms? I think we're getting pretty close now.
Your help has been great I can't thank you enough.
Your welcome
You can find Dutty's ROM here
or the Artemis ROM here
Have a quick read and see which one you think you'll prefer, to be honest I think they're both pretty similar to stock but with a lot of the crap taken out....
Just follow the steps in the first link I posted and you should be good to go.
Ok new problems.. Can you believe it.
I seem to have tried everything.
Basically I can install of a sd card, but when it gets to the end of the install and I restart instead of booting into a OS it boots to the tri colour screen, and starts the install process again.
Also, I have attempted to install via usb and have had varying success.
As I have already said, I am able to install hspl, however, when I try to flash I get to varying percentages below 30% before the whole thing freezes.
I now have an error that says Upgrade Rom code error Please Try Again.
Sorry i dont mean to hijack ! but will any of you be kind enough to help me here..
http://forum.xda-developers.com/showthread.php?t=879980
thanks !
Ok so I followed the steps and still to no avail.
I am able to boot using the sd card method, however, the same problem occurs with each rom version. Basically as soon as I reset the device it pretty much switches itself off, then I can't turn it back on, once I finally do turn it on, it restarts the process like it never happened.
The other issue is again the active sync problem.
With most of the the usb connections I am able to connect and get a little way through the install (most I've got is 15%) then it just freezes up and I get the 262 error
Your best bet is to try flashing with a freshly formatted (FAT32) 4gb, class 2 card.
I know, sounds pretty specific right?
You wouldn't think it would matter?
I have tried flashing with 16 gb class 2, failed at the radio step
Tried with a 8 gb class 6, failed at the radio
4 gb, class 2, flashed successfully.
Seems our HD2's are picky about what cards they'll take a ROM from for some reason.
Alright I'll try that, my next issue is which is the stock rom for the phone =S
It was bought in the UAE and I'm currently in Australia.
edit: Also I read somewhere that the constant bootloader screen can be caused by a bent battery pin?
Edit2: I have attempted to do that, however, now the bootloader will accept the card, then just sit on loading...
I'm pretty sure this thing is bricked.

I've heard of bent battery pins being a pretty common problem, causing usually just the phone not to charge properly. I've personally never heard of it causing constant bootloader, but it's definitely worth checking.
It's weird that it's such a common problem, my usb/charging port is broken, so I have to use an external charger. I change my battery on average twice every 24 hrs, and I've never bent a pin
Ok, new info, apparently because the device is for the middle east it does not support stock 3.14 roms. What does this mean for me? Am I bricked.

That's the post I found the info in. All of that info matches up to mine except my original image was 3.142 I think =S
Firstly, your phone is not bricked - a bricked phone is responsive as a brick.
Can we start from the begining?
What does the Bootloader Moder screen say (with and without the USB cable connected)?
What ROM (and if custom ROM, what RADIO) have you flashed and are trying to flash?

Alright from the beginning.
Basically about a month into using the phone in Australia it became very unresponsive to the point where it would not boot at all. We left the phone for a couple of months, however, after seeing a friend rom android I decided maybe it was time to attempt to fix this phone.
Some more info:
When I attempt to do any sort of ROM update there is nothing in the 'current image' part so for example it will say update to Dutty 3.6 but it's updating from nothing, does this mean there's no firmware there?
In the bootloader I have:
PB81100 HX-BC
SPL-2.08.0000 8G XE
MICROP(LED) 0X05
MICROP(TOUCH) 0X40
Without USB cable in I get Serial in the white part down the bottom, with the USB cable in + plugged into computer I get USB.
Just to further clarify. In regards to the ROM I have installed. I simply don't have anything installed. There is a bootloader, no image, no bootup. It boots up to the tri colour, that's it.
For a moment we will forget about going to 3.14 ROM: I don't know if that phone is entitled to an official upgrade to 3.14, if it is locked to a particular network, if it is branded, etc. If it is not entitled to a 3.14 ROM upgrade then you will have to go through GoldCarding, so we will leave it for now.
Make sure that the battery has had a good couple of hours charge in the charger or double that if connected to the computer.
Remove SIM Card and SD Card.
Switch on to Bootloader Mode, then connect to USB.
Download and run HSPL2 - ignore the instruction about connecting to ActiveSync etc, just proceed.
Download and install the HTC 1.66 WWE ROM - again, ignore the instructions, just proceed.
The reason for HSPL is because your phone may be operator locked (not SIM locked) and you aren't entitled to run the 1.66 WWE ROM.

[q] magldr help

Hey guys well I'm having really bad problems with Magldr and my phone. My phone just randomly restarted, then wouldn't get by the HTC bootsplash screen. But now, it won't even go in to Magldr or turn on, unless it's plugged in to my USB. So now, when I plug in the USB, the phone starts to boot up by the HTC screen then goes to the Magldr bootloader where it says From NAND, 1234 GO! screen.
But after this nothing happens and just repeats the same thing over and over again.
I've tried flashing different ROM's and different SD cards but they all have the same problem.
Any way I can fix it? Thanks.
LS
I'd suggest running a Task29 from bootloader, then starting again with installing magldr etc. I was also having some problems getting a rom to boot, so I've just returned after going all the way back to my stock winmo rom and all is good again.

Just the man I was hoping to help me lol. Is there a guide on that anywhere? I'm fairly new so don't really know what Task29 is. One thing - I tried to boot to HSPL and it wouldn't.
EDIT: After several tries, I'm in HSPL 2.08 now. Now I just have to find out how to do the rest. Do I keep an SD card in or does it matter?
Use this tool and select the option to run Task29. It formats the entire NAND area. From bootloader, connect to pc and run the tool, watch progress and as it reaches 100% hold the vol down button in so that the phone boots back to bootloader (if you miss it no biggy, just pull the battery and boot into bootloader). Then reinstall magldr etc.
You can leave the sd card in, makes no difference.

Thanks. Fingers crossed this works. Don't want a bricked phone.
As long as you have hspl you'll be fine. I've done this procedure hundreds of times
So I've ran the Task 29 but nothing's different. Still keeps rebooting. Any other tips?
Check your battery pins. Sometimes the copper pins get bent a little out of alignment. Just gently straighten them out by hand. Make sure that you are gentle in future when removing and especially inserting the battery.
You are f*cking god Clyde. Thank you so much. That's what it was. How do you know so much about the HD2? Great man. Do you have a Paypal?
Glad to have found the problem. Those battery pins have caused a few headaches, as I say be careful with them in future. I learn't just by reading the threads and having been around the block a few times . It's not necessary to give me any payment, but if you really want to buy me a pint, there is a donate link to my Paypal account just above my avatar. Thanks m8

[Q] Help on fixing hd2 that wont boot up

Hey guys I have a hd2 that wont boot up anymore. I have installed several windows 6.5 cooked roms into this device for a while now. Recently this device has been given me a lot of problems until finally it took a dump. Now everytime i power up the device it stays in the splash screen. It doesnt even show radio version, rom version,etc on the bottom left of the screen. So is this hd2 dead or is there some way that i can fix it. I even tried installing tmobile's official rom on this device by going into the "rainbow screen" so that the device can be seen by using the usb cable, but alas....it didnt work either. So any help would be appreciated .
If it doesn't install, and nothing installs, then you need to take it to repair I guess.
I had a feeling about that. I just figured there was no way to fix it and the fact that i couldnt send it back to tmobile to get a replacement was out of the question since the firmware was modified. But your saying there are shops that fix these kinds of issues? If so, I better start looking around over here.

why dont you try sd card method for flashing your rom !1! you can pm me if you need further help
Do you mean that it can't get to the boot loader screen (rainbow) or that trying to install a ROM from there didn't work? You might want to flash the original HSPL too, just to check.
What I mean is that everytime I boot up the hd2 it stays stuck on the splash screen. It doesn't even show the rom information in red at the bottom left corner of the screen. But I can boot to the tri color menu though. I have tried to install the tmous official rom by plugging the USB when I'm in the tri color menu and it always stays stuck at 9%. So is there way to fix this or am I screwed.
Sent from my Android Powered HD2 using XDA App
Try the sd-card recovery instead of the USB one.
http://www.jayceooi.com/2011/01/01/how-to-upgrade-htc-hd2-rom-through-sd-card-video/
After that, even if it fails, it shows only SPL in the tri-color screen then you are set to claim warranty.

Well my bro... i think thats nand problems or heating issues ... does flashing rom goes all ok or it stops during flashing ? if stops than check if you phone is hot - hotter than normal.
Try this : Take out battery, memory card, sim card and put you phone in the fridge for about 5-10 min ( dont worry tried many times... no harm ) meanwhile prepare your sd card to flash rom with sd card method ... to do that extract Ruu rom - stock one - download with hd2 serial nr ( winrar, 7zip etc) find Ruu_Signed.nbh rename it to LEOIMG.nbh than copy to sd card ( format you sd card fat32 and make sure it works ... 2gb will work ) take phone out from fridge put sd card & battery into phone power one phone while holding volume down key ( go into tricolor screen - bootloader) and follow procedure in phone... i hope everything goes well and you fix you phone... but if still no success than flash android or wp7 ( if you have warranty flash stock SPL and return phone).
best regards from me

i can't turn on my hd2

For several days I get tired of uploading windows 7 on your phone hd2. The first time everything went smoothly, but broken marketplace forced me to install another rom ... and after that began to complications. Reinstalling WP7 ran smoothly, unfortunately after the restart, the phone hung up on the screen where you had to enter the PIN code, the screen does not respond to touch. After reset, the message began to appear that the memory card does not work and could not turn on the system. Again I tried to upload the new rom, but unfortunately it did not help ... Later I was able to upload back android nand and somehow everything worked. Today I made another attempt to install WP7, unfortunately, only worsened his situation, which is as follows:
The phone will not even turn on, just as I plug it into usb. MAGLDR loads seamlessly, this 4-color screen as well. Unfortunately, the system loads until the htc logo appears and some animation, after that the phone automatically resets and so on.
Check and make sure you do not have a bent battery pin as a bent battery pin has been known to cause the HD2 to boot loop like you are describing.
If you do not have a bent battery pin, then I suggest you run a Task 29 and then re install MAGLDR then reflash your WP7 ROM. Also it might help if you do a total reformat of your SD card then try to boot your device with a freshly formated SD card. I know I know WP7 formats your card anyway on first boot but hey it could help. If you still have troubles after that I suggest you get a new SD card and try that. You see if your SD card does not work WP7 will not boot cause it uses the SD card as the internal memory for the device.
I don't know how, but now everything is working! I didn't do enything! Just plug usb cable, and system was loaded! I disconnect cable and it still working?!

[Q] HTC HD2 bricked, no tri color bootscreen

Hey guys.
I have a bricked HTC HD2 here. I installed Android 2.2 on it, and it ran fine for a long time. But a few days ago, it got stuck in a bootloop. It gets stuck on the Android logo and doesn't get past that point at all.
What I've tried (in chronological order):
1. AD Hardreset from aMAGLDR: erased all data, but didn't fix the problem. Kept going in bootloop.
2. AD Recovery: Failed. Doesn't get past the "GO GO GO!!"
3. Repair aMAGLDR using HD2 NAND toolkit: tried repairing (150MB partition size) and installing Clockwork Mod (150MB). Same exact results when trying to get into AD recover. Only diffrence is that I now don't have a ROM on my NAND anymore.
4. Install a diffrent rom: Tried a few of them, but they all keep getting stuck on their bootlogo (HTC, Android, ...).
5. Restore STOCK ROM WM6.5: I'd love to, but I can't get into the three-colors-bootscreen. It goes straight to aMAGLDR, even when I boot holding the right buttons (volume down + power [both short click and long hold]). I had set up the ROM files correctly on the SD card.
6. Install the STOCK ROM using the HD2 NAND TOOL: after going to USB Flash mode and installing the default microsoft drivers (it didn't want to accept the Google Android drivers or HTC drivers I downloaded earlier), the flash utility keeps getting stuck on ERROR 264: CONNECTION. The only thing I can do in the HD2 NAND UTILITY is repair aMAGLDR. Other options result in the same error. Task29 can't find the phone either.
Bottom line, I cannot (ABSOLUTELY not) get into the tri color boot screen. It sends me straight to magldr. Also, my volume buttons are working just fine.
I really don't know what to do anymore. I hope someone can help me, any help would be greatly appreciated
Did you try this?
Download an original win 6.5 ROM for your HTC device from HTC webside.
- Take "RUU_signed.nbh" from an original ROM and copy it to your SD card.
- Rename to "leoimg.nbh"
- Reset your device while pressing the volume down button

Did you even read the OP's post, clearly I think not. The OP says several times that they can not get the device to the multicolor WINCE bootloader.Without being ably to boot into the bootloader they can notflash via SD card.
At the OP you can stop trying to flash via USB flasher in MAGLDR, it is only for flashing Android RIMs, WP7 ROMs, and Custom Android recoveries. If you are positive your volume down button works then you probably have some bad NAND blocks, but that is just a guess, with out access to the bootloader you are pretty much only left with flashing Android or WP7 via USB flasher in MAGLDR.
That's problematic... The HD2 NAND utility can't flash any ROMs, since the utility can't find the device (error 264).
I've tried 8 diffrent ROMS (from http://android.hd2roms.com/) by putting them on the SD card and use the "AD SD boot" function, but none of them can get past their bootlogo... All ROMs keep hanging on HTC / Android logos. Some of them used to work in the past, I recall...
Here, try these fixes and read the WHOLE POST :

Thanks for the link. Unfortunately, none of the solutions worked. The battery pins were indeed bent, but after putting them back in place, the problem persisted.
I left my phone powered down all night and tried booting it in bootloader this morning. It didn't work. So that rules out solution 3 awell.
I've even put it in the freezer for half an hour (solution 5), but nothing changed.. Browsed through the last thread aswell, but there was no stuff I haven't tried yet. I can't even start tetris, since it keeps hanging on a blank screen aswell
The guy in solution #4 was facing the same issue (I think).
Especially the second part of the solution, where he talks to the OP. Read it carefully, and check out the post and thread he referred to.
Holy freakin..
After reading various threads through links in the one you suggested, I stumpled upon something called American Android. I was able to install it through the USB Flasher. Guess what, it booted PERFECTLY!!
My phone works again, thank you VERY much!!

Please tell what can bo done to it to get it working or where does the problem lies.
check your battery pins and also battery if it is charged.
and,
Download an original win 6.5 ROM for your HTC device from HTC webside.
- Take "RUU_signed.nbh" from an original ROM and copy it to your SD card(formatted FAT32.)
- Rename to "leoimg.nbh"
- Reset your device while pressing the volume or without press

and then you can try an android rom again..
Another solution?
I had the exact same problem. And I am under the impression that there is no solution for every case. But for me it worked to press the volume down button very softly. I tended to push the button as hard as I could, however when I only pressed the volume down button slightly it went straight to the triboot color.
Hopefully this works for some of you.
Can someone help?
Hi,I want to refresh post, becouse i have exact same problem - can't get to serial bootloader, and in MAGLDR i can use only the USB FLASHER option. If someone could tell me how to flash any new rom only through FLASHER ? Last thing i can say: my problem started from installing this app from google Play play.google.com/store/apps/details?id=eu.chainfire.livelogcat.lite (sry for that, but I can't post URL yet) it might messed up my kernel and i have no idea what to do.
