PLEASE HELP! Im going crazy because my phone wont boot! - HD7 Q&A, Help & Troubleshooting

I know Im posting a lot, but Im going crazy because I cant get it fixed! My phone shows the htc logo then dies then shows it again over and over when connected to my pc and does nothing when its off. So I got a new battery and it worked great till the battery died and now Im in the same place I started. Any ideas? Or what is the best/cheapest way to get HTC/tmobile to fix it.

sounds like it's not charging ? maybe try an external battery charger.... dirt cheap off ebay..

1 amp charger
I had a similar issue on mine where if the battery got low enough it would refuse to turn on unless you connected it to a wall charger. A PC would not charge it.

Can u get to the boot loader screen? Have u done anything b4 that started happening?

Ok so I honestly have no idea what Gold card is... But I read something about needing a SD Card Serial and for some reason when the HD7 boots up it says that it does not have a SD card will this also fix that problem?

Think you need replace your sd card

Now we getting somewhere... Remove the bottom plastic cover, undo the silver sticky tape, you will have enough space to release and reinsert card. Note you cannot remove it without removing the screws. Sd card slot is next to the sim card. Hope it fixes ur problem

Should I try formatting the card on my computer and if so what format? Fat? Fat32?

Will not be able to format with PC. May be an old nokia but the original card is encrypted. If I was you I would try new card, or any card laying around and see if the phone reads it.

Sd card problems

First problem is that when I connect the phone to my computer the sdcards don't appear, it did a couple of builds back, I'm sure it worked in #81, so it's quite a hassle to transfer files between comp and phone. The second is
That the phone looses the sdcard a couple of times per day so I have to reboot the phone to get it back.
Anyone else having these problems and know how to fix them? Thanx in advance dear xda developers

Have you simply tried with a different SD card? Maybe its faulty?
No haven't done that, might try that thanx for the tip! Btw the card works good in the phone
Sent from my Optimus 2X using XDA Premium App
Nopes the other sd card didnt work either. Ill take this as CM7 is fubared when it comes to connecting the phone to a computer and the SD card in that situation :/
i am having the same problem, still searching for the answer....
maybe the connectors aren't aligned
I would assume that the connectors are working since the sd card works perfectly in the phone quite annoying that i have to remove the sd card and connect it to the computer everytime i want to move something big..
Btw, the sd card doesn't disappear now, i guess they fixed it in some build

Urgent please help

Hi guys
Sorry for being a noob, i just got my nook today and all was working fine stock,so i decided to try the mod. I wrote the early 3 emmc to a 2gb micro sd card i had then i put the 3 zip files on the nook root internal copy cwm-recovery-ovation-6, cm-11-20140207-NIGHTLY-ovation, pa_gapps-modular-full-4.4.2-20140207
I then turned of the nook popped in the micro sd then turned it on and the screen just went black now it stays black with slight glow my pc sees it and i am able to view all files on it but it will not boot up so i can use it.
Please help i know i probably used wrong sd card or something and have tried the various holding down buttons but nothing works
Thanks
Hk
Anyone please???
Doesn't sound like you actually flashed anything just booting won't Bork your nook. Sounds Like A Bad Device Does It Boot If You Pull The Card And Hold power for 20 seconds

Sounds like you let the battery go below ~15% or so. It cannot turn on if they battery is too low; Needs to be charged until it has enough power to start up.

Surely someone has come across this before??? Is there not a way of sticking something on the nooks internal memory to help or a micro sd card????
The one i put into it as mentioned from the start was not class 4!!! could this have been a issue, is it worth trying a class 4 card with something on it that would help??
Cheers

Try making a new bootable CWM SD by going to my HD/HD+ CWM thread linked in my signature and follow item 1a. See if that boots. If it does not, try a different SD. Report back.

Have you tried hard powering it off? Just hold the power button for like 15 seconds. Then try rebooting.
I reread all your posts. It sounds like you have a screen hardware problem. It may be time for a warranty exchange. Just take it to the nearest B&N store.

Micro SD Card Wiped, Any Hope?

Looks like the 4.4.2 has wiped my micro sd card...did this happen to anyone else? Not rooted, nothing fancy, just can't believe it wiped out all of my pictures...no chance of salvaging this is there?
Sent from my K00C using XDA Premium 4 mobile app
how did you get to 442? What did you upgrade from and how? Unless it was low level formatted, you can usually recover all the lost data usually with a program on a Windows computer. Did you try to eject then reinsert the memory card?
If it really has been wiped, try photorec (http://www.cgsecurity.org/wiki/PhotoRec). You should run this as soon as possible, without writing anything else to the card, to maximise your chances of recovery.
I would recommend Foremost. It helped me twice.
Thanks y'all, I ended up using Cardrecovery (www.cardrecovery.com), and recovered 4000+ pictures/videos, so I'm GTG. Although testing some of the random vidoes don't work, but I was more interested in the pictures anyway.

Constant Sd card unexpectedly removed issues

Note 4 unrooted 5.1.1/ 64gb Samsung class10 sdhc this is chronic and happening multiple times daily. It seems to have started to occur when moving files from internal memory to card which shouldn't be a problem. I wonder if there is a way to have all downloads go directly to sd rather then moving them with a file manager which seems to have borked the file structure causing these errors. Just my guess. Anyway I haven't found any definate fix so would appreciate any input. I have most of my apps on the card so it is really inconvenient.

If it's new, the problem is almost definitely the card; unexpected from a Samsung card but it's definitely possible for any manufacturer to sell a dud. Hopefully an exchange/return is possible? If I were in your spot, I would stick with Samsung and just chalk this one up to "luck of the draw".
I've got quite a collection of cards and most have been problem free (the only brand I've sworn off is SanDisk because almost every one of their cards that I've had has worked fine for a while, then suddenly it's still readable in a phone or PC, but impossible to write to) but the only time that I've had the unmounting problem that you describe was with a brand new card that was clearly no bueno. Good luck!
Im going to try to format the card, fat32 save all the data, and replace it. It just started occuring after moving files like downloaded images and music, so I think the file structure is causing the dismounts. Also the apps that are loaded on the card have the icons disappearing sporadically.

Where did you buy the card from?....is it authentic
I'm going to blame this one on root. .

Ok not rooted, and the card was
purchased from Samsung with my Note 4 discount. So I have a possible fix for any with this issue. I thought it might be related to wireless charging bc it coincided with this, but it may be because I transferred wallpapers and lockscreen images to external sd. I moved them back to internal storage and havent had a dismount. If it occurs again, Ill format the card. May do a factory reset as well just to kill anu bugs. Can you recommend a good backup method for non root? Ive rooted so long and used Titanium, but obviously cant on a stock device.

It is a bad sd card. Yes, it is new, but it is memory. It fails. I have had issues like this across all cards. Sandisk, Kingston, & Samsung too. It happens.

Ok Im surprised because it worked for about a year with zero issues. Now my macbook pro wont recognize the phone as drive at all. AFT says "no device" uninstalled kies, not sure if I had it but ran uninstaller, nada. Just charges, not recognized as usb device. Im at a loss. Formatted card, about to do a factory reset. Alot of apps on that card so I'm missing those apps. Odd because with the adaptor I was able to move files on my mac from the card but not to it so its not writable.

I see the same problem. Does it a few times a week. Haven't tried replacing the card though.
Well reset did not help. The card is bad,but the phone won't be recognized as a USB device at all and it's out of warranty. I lost contacts which I thought were automatically backed up to google. Maybe they're stored on the sd. Used to store on the sim or at least was an option. Now endless headaches due to reset. I didn't root just to avoid this kind of stuff.

I had this happen a ton when I had an S4 with multiple cards. It just couldn't handle 64gb, but my wifes identical phone could. Maybe your note just has a glitch. First thing is to return for another card though.
The media scanner and it will suck the life out of your battery as it scans every time the card is 'inserted'. This can be disabled though.
I have a 7 year old or older 1gig sandisk class 6 in it now and it hasn't dismounted it yet, though I dont have any apps on it yet.
