[Q] HD7 stuck in boot loop

Hello to all, a friend gave me his HD7 to look at for him to see if I can get it to work but I'm stumped!
Here are the symptoms, when NOT connected to PC by USB phone consistantly reboots up to "connect to PC" screen and then shuts down and boots up again automatically and repeats untill battary is pulled. As soon as I put the battary back in starts back into boot loop. I have tried to load bootloader screen (pwr+vol dwn) and (vol up+vol dwn+pwr) to re flash and no luck, it never gets to bootloader screen and continues to loop. I then downloaded Zune software to try and restore through Zune but when I conected the phone it now stops loop process and stays on "connect to PC" screen but Zune gives me restore error "C101002E". While in this state I shut down Zune and tried load bootloader screen again and nothing I even tried using galaxy s method (vol up+vol dwn+plug in USB) and no luck. Is this a lost case or is there something I'm not trying ? Thank you all for your time and please pardon me if I have my terminology mixed up as I am new to the whole Android and WP7 Scene.

is the phone in a case? are any of the buttons being pressed whilst the phone powers up (such as the camera button)?

Sorry I forgot to mention that. No, there is not a case on it. As I was digging arround I did come accross a few posts advising about the case causing malfuction due to pressure on buttons but I do not think that is the issue. The reason I say "think" is because he did have a case on the phone when the issue started happening, is it possible that the case could have caused permenant damage ?

possibly but many people who registered the issue said that the phone worked normally after not having the case on (from memory). it's quite strange. have you tried googling the zune error code you got?

Yes I did and no results, all I was able to find was a handfull of other HD7 owners with same issue, one even stating that he went as far as even searching Microsoft for that error code and they did not even have an answer to the error code which is pretty scary. there was also the occasional few that pluged up the phone to their pc, pulled batt and popped it back in and phone booted up normally but not for me.
Do you know if the HD7 camera button is a 2 stage button that focuses on half press and takes pic on full press ? Reason I ask is because I'm not feeling a finall click when full pressing the camera button.

it is a two stage button (all windows phone 7s are). the first first you should feel just as you push it a bit, and then next is when you push it all the way down. if you don't feel it "click" (in your fingers) when you push it all the way down, it could definitely be that the camera button is jammed. if this is the case, i would suggest using the warranty and getting a replacement either from the carrier or htc.

I think we are on to something here I just had another buddy come by and bring his HD7 and it feels completely diffrent! The 2 clicks are easily identifiable on his phone but there is no second click on the problematic phone. At this point I am 95% sure that the camera button is the culprate but that 5% variable is driving me nuts so I will be doing some very carful "non warranty voiding" partial disassembly to see if can make this a 100% confirmed post and see if there is an easy solution for those that wont have a warranty exchange option in the future will be back tomorrow with update.

if you still have warranty i wouldn't risk voiding it, even if you bend the back to get the plate to move out of the way. i'm pretty sure htc can tell when a device has been tampered with (though carriers normally can't).

HTC will most deffinatly know if a device was tampered with because usually even if you bend the backplate i would think that the plastic will show signs of force on the stress point where the screws are not removed and I have still not been able to remove a lower lid with out showing signs of it being removed (minor scuffs or scratches to lower plate). With that in mind I would NOT recomend this if you are outside of your carriers exchange period if that is the case just do a warranty exchange. In our case he is still with in he 14 day exchange period with carrier where they only check for extensive exterior damage and the infamouse liquid damage which we are clear of. So regardless the results that I come up with he is going to be exchanging the phone in store with carrier, gotta love those brick and mortar return polices

here are the results I'll try to be as detailed as possible and will also try to upload some images.
The camera button was the problem and was easily resolved here is the process. I removed batt lid and sd card lid (lower lid with metal strip) grabbed my t5 driver and started started removing the all the screws ( for more details on that part do a search for "HD7 SD card upgrade") here is were it gets interesting, once I removed all the screws I pressed the camera button and it was now working properly !! I fired it up and it booted up normally with out any issues. I put all the screws back in and decided to check it 1 more time before putting both of the lids back on and the button felt wierd again I powered it back up and sure nuff it got stuck in boot loop again. Here is the solution and remember as The Gate Keeper stated none of this is worth the hassle if u are still under warranty just send it out and get a new one
Remove all screws from back plate with a t5 torx driver (I removed all but 1 screw to avoid removing warranty sticker on screw head). Once all screws are removed gently lift of rear plate, it should come off easily if any extra effort is needed revise that all screws are removed.
once back lid is removed you will notice that one of the torx screw is located right next to the camera button area this is were the problem is created some how when the back lid is screwed in that screw is causing the back plate to apply pressure to the button mecanisim area not allowing the camera button to make proper contact with the switch when fully pressed.
my solution was to put a tiny strip of 2 sided tape right by the torx screw so that when it is put back in the thick 2 sided tape will keep the necessary clearance between the back plate and the button mechanism. I will try to post pics asap!
hope this helps anyone with this issue feel free to PM me with questions.

If you have a HD7, your phone is defective. I had the exact same problem, took it back to Tmobile and got a new one and it works perfectly.
Things you will try to do and which, for a short amount of time will work:
1. Remove and re-insert SIM.
2. Hard Reset
3. Connect to PC
4. Remove from case
5. Walk into store to complain.
Trust me, phone is just broken. Return it and get another one or be in for a world of hurt. HTC HD7 owner.

I am having the exact same problem. Just received my brand new HD7 today from T-mobile. Was excited to power it on, but it never made it through the "connect to PC" screen and constantly reboots itself. There is nothing you can do on the phone, all it does is that it shows the HTC logo, then a picture indicating connect to PC, then reboots itself.
EDIT: Problem solved by sliding my fingernail into the little hole next to the camera button to unjam it. However everytime the camera button is pressed all the way down it gets jammed again.

Correction : not going into both recovery or download mode ...

Since your device hit the wall with its head, it had entered into a short term memory loss, can't really remember how to start up anything.
Well, in this case there is hardly any software stuff that's going to help you unless we find and fix what little part is damaged, which circuit got shot or broken memory. maybe they are not looking it up nicely, or don't want to use their brain to track the origin of the problem.
The device is starting, its even taking in power from the charger, so it's safe to say the initial point of contact is safe no short circuit, the contact with the power button is safe too. you said it goes into download mode but, get restarted soon enough, it even shows the boot screen, and the battery icon but get restarted again and again. why data is not getting read?
Well the answer lies here..Have you used a CD? what happens when it gets scratches? an old hard disk? spin..click cluck cluck..spin cluck cluck.

Sooo ... What should I do at this point !!!!! ?
"spin..click cluck cluck..spin cluck cluck" Master

well, since your device had physical damage, it's hard to say that it can be solved with only flashing or de-bricking.
Getting internal emmc changed could be an option, but it will need an experts hand. that would be the safest bet for getting this repaired.
but if we assume it's not damaged or corrupted, cause the device can reach to the point of splash screen and enters download mode.
then, corrupted OS and partitions can be a suspect in this case as well.
did you flashed anything on the device before? custom roms?
can you post a pic of the device when it enters into download mode?

Thanks Billysam for replying ...

Yes ,, I HAD COSTOME ROM INSTALLED AND IT WAS WORKING FINE ALSO
And downloading mode can be seen for a one or two seconds .. need video to show
All the screen works for one or two seconds only and restart .. it feels like some pressing the button to restart immediately ...

We can do two things right now..
1- Try to boot in safe mode..
Hold power button, for 2 or 3 second and keep holding down button as long as you don't see the lock screen with safe mode written on it.
delete all user apps installed.
2- try this method
http://forum.xda-developers.com/showpost.php?p=63949797&postcount=4
Most of the ways that we can try here is after download mode stays as long as you can flash anything, or get into recovery, without them, these are the only 2 option I can guide you to. hope it get back on. good luck

Thanks Billysam ...
No safe mode
and
debrick didn't work
nothing happend
and also dear Billysam it goes into dowloading mode but for one second and restart immediately that was the case always just to make it clear ...

Well you've come a long way, what really is causing this now is hard to guess.
1. The device suffered physical damage,
2. You took it to many mobile repair stores, maybe something they fixed, something they broke, something else they flashed.
3. You tried almost all the ways possible related to software issues. there are none left.( if you find another let me know)
considering it just get restarted everytime you switch it on after a second or two, it can be any hardware any chip or ic related to the initial startup, just like i said if we think its emmc, it may be a faulty wire sending wrong volts, a bad resistance or capacitor, somewhere in the motherboard a blockade, or the ram cant access memory. who knows? unless you take out all the parts and see where the damage is, or just take them all out and put it back where it should be placed or replace few and keep trying and tracking all the way or just throw it again on the wall, or give it an electric shock. from simple to complex there are many ways and you can't be sure which will work.
but none more than already said. i hope this concludes our troubleshooting.

Hello Billysam,
5 points and 5 points only needed to mention .. May be you are right troubleshooting is over .. But for future consideration .. And small brainstorm ..
Point No. 1 :
Mobile repair store actually did not damage, broke or misplace and thing in my phone because they did not open it at all ... As soon as they saw the phone they its software related problem though I mentioned that the phone has an accident .. One of them actually told that if its hardware related (emmc ic) it will show the samsung logo and then restart .. even that one them told the solution is JTAG ..
Point No. 2 :
I had second S duos which I gifted after I did mix of the parts and reached to conclusion that the problem is the board which has every thing intact
piece by piece cause I separated every little part camera, led, speaker and antenna even the screen with the touch working perfectly fine the accident did not harm the screen in any way not a scratch ... And also I rooted, custom rom, stock rom with odin and custom rom again and phone was working fine with no problems till it hit the wall .. I know pretty much every thing about boot, recovery, recovery mode, fast boot and adb shell and also download mode ..
Point No. 3 :
The phone show the start screen and even download mode but as soon as it shows those it restarts .. I even made my own JIG .. whic works perfectly with other samsung phone goes immediately to download mode .. but my phone starts but nothing on the screen and restart like before ..
Point No. 4 :
Debrick !! what does it do ??? !!!! because it didn't do any thing to my phone ... it need little explaining so may be I did some wrong with the steps .. And I used 2 g.b. external sd card .. Is it compulsory to use more then 2 g.b. sd card ??!! ... ( what it had to do with starting dead phone and how ?? ) ..
Point No. 5 :
Used to and currently also using Nokia phones in their flashing program there was a mode of dead phone flashing which does not require starting phone full dead and flashes fine .. Isn't there a method like that for samsung a program or something ... yeah may its the JTAG ... I mean some thing with usb cable like fastboot or any other android commander or event trough connecting it with another phone ...
Sorry for inconvenience ... thanks alot ....

[HELP] Nexus 5's Screen Goes Blank After Boot, Even After Restore

Hey everyone,
I need a little bit of help. My Nexus is having a bit of an issue. I've looked around but can't seem to find anything similar.
The phone boots completely, shows the boot animation, shows the lockscreen with notifications. I can drag down the notification bar, turn on WiFi etc with no issue. As soon as I either unlock it or click on settings, the screen goes completely blank. Safe Mode does not seem to make any difference.
I've done a Factory Reset using Recovery mode and now after booting it shows the Language options for setup and the screen once again turn off. Pressing the power button after that gives a clicking sound but no picture. I've uploaded a video here https://gfycat.com/PoliteCommonAmmonite
Any clue what I am supposed to do?
Thanks for your help!
Variant - hammerhead D820 16GB
HW Version - rev_11
Bootloader - HHZ10x
Signing - production
Secure boot - enabled
Lock state - locked

Has no one encountered this issue before ? I'm very rusty Android-wise and haven't had much chance playing with Nexus devices.

maybe hardware issue

I have similar problem.. turn on n5 and when not moving it works fine, I can get the phone on,
The screen flickers and goes dark or touch won't work are some occurrences. Phone still works ie gets sms and etc. With research for a few weeks. Seems that it's not software related but hardware related. I am hoping it is a flex cable problem or a loose cable problem which is cheapest. If a screen replacement is needed then it's not worth the work. Just buy a new phone. I got mine secondhand at a way cheaper price. Too bad cuz I like it it's nice enough for me.

I'm fairly certain this is software related as :
1. The screen plays the turn off animation (a-la old CRT TV) when it turns off
2. The screen turns off at the same time everytime it is rebooted (and before the reset would stay on until the screen was unlocked)
3. The power button still works to reboot the phone.

Hardware or software

To make sure it is not indeed a hardware problem we should perform a sort of "hard reset" (not to be confused with button combinations to reset the devices software) . Turn off the device if it is on. Take off the back cover, remove the six silver screws holding the plate over the motherboard. Once that is off you should firstly lift the battery flex cable up gently. (see sample pic) With doing this we ensure that all power is gone and no other components will be shorted. The idea here is lifting and reconnecting the the flex cables and wires to make sure everything is really how it should be. (resetting them all) Basically tearing it down. I would just unplug the battery and then unscrew the four screws at the bottom to access the LCD flex cable underneath the speaker. Lift and re seat the LCD connector and reassemble the phone (battery being last thing re seated)
It doesn't hurt to try this method to rule out the hardware side. If you don't know how or need help PLEASE contact me first for advice so you don't end up with a broken Nexus 5.

Two things.
1. question if done this process and the problem still comes back what does that rule out? If the problem does not come back then the problem was hardware?
2. I did reseating but did not reseat one cable or maybe all of the flex able connectors and the battery was still in place. and it was not connected last, rather it was first i just took connectors on and off and did not want to mess with the black wire as it was very thin and small.
Result of #2 was that the problem went away for a while, seemed to "help" but did not fix it completely.

unlock ur bootloader ! flash a rom and install any kernel which supports colour profiles like Elementalx flash then open kerrnel manager and change the colour profile to vomer_amoled if u like it! or back to stock!

Alright so I've done so far :
Reinstalled stock from scratch (Still the same issue)
Unlocked bootloader
Installed TWRP ( I can play around in TWRP with no issue whatsoever, screen doesn't go off)
Sideloaded Pure Nexus, GApps and blu_spark91 kernel
Tried scraping all of that and going with CWM and CM, still no dice (although the sound is different!)
STILL THE SAME #!&%$ ISSUE. But now I can select the language. When I click the yellow arrow, I get that same issue where I can't turn the screen back on. The power button still plays the lock/unlock sound through the speaker.
I should also mention the power button works perfectly when using TWRP or CWM.
I have no clue what the hell I am supposed to do now..... Please help. I've never opened the phone myself.

Hello, I would like to suggest a hardware cleaning of the power button. It may or may not help, but I assume you would like to try something different to remedy the issue.
https://www.youtube.com/watch?v=doPuXkQTGbc
The video shows how to remove the motherboard in order to clean the power button.
I had done this on another Nexus 5 that turned off randomly. I didn't want to replace the power button but cleaning it removed the problem for me.

Phone stuck in a full screen app that cannot be closed? Touchscreen only works locked

Hello! Here's a problem that I believed no one has had before. Or at least I do not know what keywords to use on my Google searches to find anything similar that has happened to anybody.
It happened when I was looking at Instagram stories, suddenly a white bar appeared in the middle of the screen with the whole screen half faded to black behind it.
Here are two screenshots that I was only able to get by connecting the phone to my PC.

}
The phone otherwise works normally, the touchscreen works only if the phone is locked because when I unlock it the white bar reappears and I'm not able to get to anything that's behind it.
I have pretty much tried everything:
Booting in Safe Mode does not close the bugged app (could be Instagram)
Wiping the cache does not close the app or remove the white bar
Reflashing the firmware with ODIN with the same version (phone is up to date with the last 7.0 stock rom) does not close the app, the white bar comes back as soon as it's turned back on and unlocked
Needless to say, restarting the phone does not work
The only solution I can think of would be a hard reset, and that would be fine if only I could press ALLOW when trying to backup all my data with Smart Switch, except I can't get to the ALLOW button because of the freaking white bar and therefore can't give Smart Switch permission to access my god damned phone.
If y'all have a solution I'd be forever thankful, otherwise I'll guess I'll have to hard reset without backing up anything. Which would really, really suck.
Isn't there a way to kill all apps at once? Without having to access the phone I guess lol

Okay I've made progress. When I activate the airplane mode and restart the phone it doesn't happen But when I turn the data/wifi back on, the white bar pops up.
So it's has to be a background app with internet access showing the empty white bar. At least I can back-up my data now tho, but I'm trying to figure out which app is causing this because this is freaking gamebreaking and has to be reported.

I have exactly the same issue, started yesterday morning. I tried restarting the phone a couple of times and it got rid of it for the day. But the white bar reappeared again this morning...
The bar doesn't appear if the phone starts on flight mode. I noticed that a small prompt saying "No connection, Can't download attachement" appears at the start up of the phone when in flight mode.
Can't reset the phone through the menu (needs connection to verify samsung account password which only brings back ). Had to hard reset by turning off the phone and restarting it by pressing the home + volume up + power buttons together.
So far no white bar reappeared.

Yep, had to hard reset. I backed up everything twice (smart switch and TWRP) so I lost nothing fortunately.
I gave up on trying to figure out which app was causing it though, it hasn't happened again but god damn was it annoying, whoever is responsible needs to fix it asap.
(it wasn't instagram btw)

Hi, I'm having the same problem right now and seems like we are the only one who have it so there's no other solution other than keep the phone on airplane mode... but I can't back up my data using my cable and smart switch, and I don't want to lose any of them ( My phone can work without being on airplane mode but whenever I open wifi, the white thing return...
I tried to let the phone on safe mode to check if there's any app causes this problem but with the wifi on, the white bar reappears so I guess it's not the apps' fault :-s
Any ideas guys?

I don't know why, the driver of the phone still exist on my laptop and there are folders too but when I clicked it, it's empty ( I looked through Properties ) and when I copied to another driver on my laptop, the window is frozen and closed itself I tried Develop Options to configure USB but it didn't work either...
And do you guys still have problem connecting wifi? Cause I'm still having it. I can put my phone on normal mode ( without airplane mode ) and send msg but whenever I open wifi and 4G, the white bar emerges...

Use Smart Switch to re-install the phone's drivers
I'm not having the problem anymore because I did a hard reset but I backed everything up with SS.

Witson PX5 Android 8.0 unit stuck on recovery screen

Hi guys, first post here.
I recently purchased a Witson V5754 unit for my Astra J which is an Android 8.0 PX5 unit with no external buttons. Everything is controlled by touchscreen or the factory panel buttons and steering wheel controls.
The unit was working perfectly but froze up and couldn't get any response from it. When I switched off the ignition, and then switched it back on again, it came back with the same frozen screen. So, I pulled the radio fuse to cut the power to the unit. On re-inserting the fuse, the unit powers on with the initial multi-media nav splash screen, then followed by a black screen for about 5 seconds before going into a recovery screen saying that it can't load android and my data might be corrupt.
This screen gives me 2 options - try again or factory data reset. The problem is, with no external buttons, I can't move the highlight to choose anything on that screen!
Any ideas, guys and gals?
PS - I would upload a pic of exactly what it says on the screen but due to forum restrictions in my first posts, it won't allow me to attach the pic

I recently purchased a Witson V5754 unit for my Astra J which is an Android 8.0 PX5 unit with no external buttons. Everything is controlled by touchscreen or the factory panel buttons and steering wheel controls.
The unit was working perfectly but froze up and couldn't get any response from it. When I switched off the ignition, and then switched it back on again, it came back with the same frozen screen. So, I pulled the radio fuse to cut the power to the unit. On re-inserting the fuse, the unit powers on with the initial multi-media nav splash screen, then followed by a black screen for about 5 seconds before going into a recovery screen saying that it can't load android and my data might be corrupt.
This screen gives me 2 options - try again or factory data reset. The problem is, with no external buttons, I can't move the highlight to choose anything on that screen!
Any ideas, guys and gals?
PS - I would upload a pic of exactly what it says on the screen but due to forum restrictions in my first posts, it won't allow me to attach the pic

If you have a reset button (a small hole that could.be pressed helped by a needle) use it for moving between options (short press = move. Long press = accept the chosen option)

Hi, have you solved the problem? I have a similar problem with my full touch px5 and I have not found any reset buttons from the unit or the screen.. So now I can't get out from recovery mode. Reversing camera works tho.

That Unit (Witson V5754 unit for my Astra J) has no hardware reset button !!!
The hole right next to the SD slot is fake.
Only solution is to open the display part and solder a button to key2 + gnd.
I know, because I have that unit myself and tried all the buttons + combinations, no sauce.
EDIT: Search in my posts or in the hardware section for more info

Thanks, will try it soon. I have Witson V5637, but I think the HW is the same.

I have the exact same board under the screen, but I couldn't get it to work. Tried with key2, key1 and rst, all with ground. The idea is to get the key2 to ground with the button? When I powered the unit the key2 didn't got any voltages so if it is activated with ground, it is not obviously working.

Please find my posts about it.
You need to wire LED1 or 2 .. cant recall, because it functions as indicator.
What the key on single press does is MUTE
Long press powers off the screen and keeping pressed the HU goes to sleep or even longer pressed, reboots.
The indicator starts lighting up when pressed long enough for reboot and start flickering after, where you start to release-push until you are in recovery.
-> Since the mid-long press shuts off the screen, it could happen, that your screen stays black -> press again to power on the screen.
EDIT: Yes, key+gnd does it.
You can even map this new keys in the keystudy app now, because they're resistive.

Didn't work with this wiring: key 2 (or key 1 or rst, tried them all) -> switch pin 1, gnd -> switch pin 2. So when the switch is pressed, the key is directed straight to gnd. Should I do something differently? I don't need any indicators, just need to get out of recovery mode.
I have checked the posts in different thread you mentioned, but they are as jibberish as other answers

Most ppl try to even enter recovery for that, the indicator helps a lot.
If you are in recovery already and need to get out, key2 long press should activate the highlighted entry. This is also mentioned in the top lines in recovery.
key2 pulled to gnd will do. Assuming you use the gnd provided by that connector.

Yes, the gnd was from the same flex connector slot. Checked with a multimeter that it is also a shared ground and the switch was properly wired. Still not working with the switch.
Lyckily I got an usb keyboard. I plugged it directly to usb1-port at the back of the HU while powered up -> didn't work. Then I left it plugged and powered the unit completely off (not even power to memory) and on again -> the keyboard starts to work and arrows/enter key did the trick!
Thanks for your support although it didn't solve my case (which is strange because of the same HW).

is there any way to use the recovery without rst button?

At the outset, I'm sorry for digging up the old topic, but I can't cope with my device at all. After connecting to the power, the device displays the Android 10 logo for a second and then the screen is black. I need to enter recovery mode, but like the user above, my device does not have a reset button or any other physical buttons. After disassembling the device on the board, behind the display, I found pins as in the picture, ie RST, RST1, GND1, GND2. After shorting the RST and GND1 pins, you can see that the device is restarting, which I suspect is like a reset button (?). I will be grateful for any help on how to enter this recovery mode.

For MTCD/E, I've posted some hardware methods for entering recovery.
