[Q] HTC Desire Z constantly restarts

Hi, i have a problem with my phone i could not find any solution online.
Two days ago the phone was in my pocket in sleep mode. I took it out and it was closed, no button was responding, i took the battery out, put it back again and started it. It asked for the pin code, i entered then it said "unlocking sim card" then the phone restarted.
From that moment it constantly restarts, regardless of me entering pin code or not, it restarts. I use stock firmware and i didn't do any overclocking or any modifications to the phone.
I tried the boot screen (the one which is entered by pushing yolume down+power button) I did factory reset from that screen, it didn't help. I put the phone in recovery mode and a screen appears and nothing happens, i think it is like a dfu mode in iphone, i don't know how to use it. In the boot screen a green text screen appears for a second says "PC101img.zip is missing" or something like that.
Do i have to load the rom again to this phone? If so how can i do that?
Any help will be appreciated.

Hey,
i've never heard of this issue on any phone.
So you coulds just try to do a few things.
First you could try to flash a new radio ROM.
just see the android developement section and the radio thread.
the radio doesnt change the actual rom on your device so yiou wouldnt loos your data.
it might help it might not, as we dont know what the reason for the issue ist.
when does it reboot? when you enter the sim code?
try a different sim card, just to see if it still happens and/or try to remove the sim passcode.
this might help and might help to see where the issue is...

Thanks for the answer. I didn't try different sim card but i tried to start the phone without the sim card and the sd card. It didn't change anything, it still restarts after few seconds.

I don't see how a new radio would affect the phones sim card...
Sent from my T-Mobile G2 using XDA Premium App

The problem seems to be with the sim card. I changed the sim card of the phone and it didn't restart from that moment. I used vodafone sim card with the phone for a week and after a week sim card started restarting the phone.
Is there a known cause of vodafone sim cards doing this?

Re: Constantly reboot...
the same issue does happen on mine! Stock firmware, never rooted, however, I've tried using different SIM cards and removed SD card, the same situation still exists. Reboot and reboot... please help!

Yeah, and randomly suggesting to flash new radios for a problem this person never heard of before is not great advice. Bricking the phone is possible when radio flashing, and should be approached with caution, and only done when there is a radio-specific issue.

HOX won't boot

Hello, i'm sorry that my first post on this forum is an question about my no longer working htc one x. I have been gathering information of this forum for a long time, and allways helped me, but this time i am really stuck. So in advance i thank you for all the help you already have given me
This is what happened
my first HOX had a defect sim reader, was declared DOA so i got a new one, so far so good
but after using the phone for about 2 weeks,
all apps started closing one at a time, untill the phone went black (it was still on, but nothing was working)
at first i tought i installed a bad app, so reset the phone to factory settings.
after i did that it worked for a few days untill the same phenomenon happened again.
this time i reset the settings via the power+volume button boot menu, and in android wiped the SD card.
again it worked for a few days,
untill it all started going haywire.
all the apps i installed the last time where whatssap and dropbox (no games and such)
now i rarely can get my phone to boot, or go into recovery.
when i connect it to my charger it has no red light.
if i get it to boot, i usually cant get past the sim unlock screen.
i have been thinking about returning it, or installing another rom (wich i have done before on my htc desire wich worked great)
problem is, i cant go into android to tick on the usb debug.
sorry for the long post, i'd be really happy if you could help me out in this one.
my htc is from the dutch vodafone provider.
cheers,
Schella

mmh i read about same problem with someone, here on xda, are your bootloader unlocked?
it seems to be a firmware problem, so you can try to install a ruu if it's available, and if it's not, you can try to ask for htc or vodafone to change it with another hox, or you can unlock bootloader and install a custom firmware, hoping that it will not give you the same problem! (unlocking bootloader MAY void all or part of your warranty)>>it depends only from htc... in some country they don't care, in some other, they will not repair it.

aha

i believe it is alowed here, but this was exactly my dilemma.. i think i'm going to return it for it is the safest option i guess. Maybe it is an hardware failure. thanks for the reply! my bootloader is locked btw

HELP! McAfee thinks my phone is rooted and locked me out

So a little background first. Over the past couple of weeks I've been having an issue where my phone just all of a sudden tells me that my sim is not recognized. Usually a power down and back up fixes it, but it's been getting worse and worse. I tried getting a new sim card but that didn't help.
So today the problem occurs again, and when I restart I get a McAffee screen telling me my phone is locked because it's been rooted (it has not). From what I can tell, the only thing it will let me do is enter a pin that I don't know. Do I have any options here, or am I totally bricked? Any help would be appreciated, I'm starting to panic.

Don't worry, your phone till okay.
the last option you can do is hard reset or try to flash stock

Your device is corrupt ... Red warning

I know that this issue has been discussed several times here on the forum, but I couldn't find a solution for my situation. So, kindly bear with me.
I was talking on the phone when it slipped and fell down to the ground. When I lift the device, the screen was fine but the touch was not working. I couldn't draw the lock pattern or type the password or anything. I restarted the device several times but without success.
I found a youtube video on how to open the device to check the screen flat cable. I opened the device and checked the cable. It was a little bit loose, I secured it and put everything back. I turned on the device and the screen worked, but it gave the message "Your device is corrupt ..." (Red warning).
The google support forum said that this warning is due "tampering" with the OS. This is not my case because simply, I don't know how.
I tried "Factory Reset" several times, but wasn't successful. The device keeps showing this warning and when I continue, it works for half an hour or so before it restarts again, and so on.
My problem now is that I don't know if this is a hardware or software problem.
I really appreciate all your help and support.
Best Regards,
mwahid

That is what shows up on every boot after you unlock the bootloader. There may have been a short circuit of some kind and was viewed as tampering. It affects nothing in the way your phone operates but affects warranty.

If it is really bothering you, you can try to flash the factory image and relock the bootloader. Then re-unlock the bootloader to see if that gets rid of the problem. However, as stated above it does not affect how your phone operates; so personally I would just leave it.

Thanks for your reply.
The problem is that the device is not working properly. It keeps restarting every half an hour or so and sometimes it hangs even when I am not using it.
I checked the bootloader from the fastboot menu and it is locked. I didn't try to unlock the bootloader or reflash the device. This message appeared only after I opened the device to fix the screen.
I will try reflashing the factory image and see what will happen.
Thanks again for your help.

I followed this guide to the letter, but the problem is still the same. The phone works for a few minutes then suddenly restarts and displays the message "Your device is corrupt ..." (Red warning)
I really appreciate any ideas.
Thanks

Hello again,
Could a hardware malfunction be the cause of this problem?
I just want to know so I can evaluate my option whether to fix it or buy a new one.
Thanks,

1+3 motherboard problem

After downloading Oreo with mobile data when i start installing, phone switch off and doesn't switch on. I tried everything even went to care. They tried hard factory reset but it could not help. They told me only that problem with mother board aka PCB. They can't do anything except replacement of it. It is not wisely to do it.
so whats next?

Do you try unbrick guide?

you hard bricked your phone. you need a pc to unbrick it unfortunately. But your mainboard is okay haha. its just software.

FWIW, it might be just a coincident. My PCB died randomly two months after purchasing it (i was rooted with custom rom) - sent to the support and got back new (with different IMEI) within 3 weeks.
