Constant Rebooting - One (M7) Q&A, Help & Troubleshooting

First off, I apoligize if this has been mentioned before. I did do a search and looked at a few pages to find that this hasn't really been brought up much. Or at least not often or recently.
I have a M8 now, but I gave my old M7 to my dad whos been attempting to use it (and enjoyed it while it worked fine.) But now the phone will reboot itself almost every 10 minutes no matter what I do.
I have
- Unlocked the Bootloader
- Relocked Bootloader and ran an RUU
- Unlocked Bootloader and Installed Custom Rom (AHRD)
all of which have not fixed the constant reboot problem. I was wondering, could the issue involve the firmware of the phone? Or is it a hardware defect.
When I gave my dad the phone he had to take it to best buy to replace, assuming they gave him a refurb I am curious whether or not that could be an issue of a loose part as well.
I have not tried to install a nonsense ROM.

[Q] Random reboot into bootloop- cannot access recovery. Please help!

a few days ago my fiance was complaining her basically stock Nexus was rebooting into a bootloop - where it displays the loading X and vibrates and then reboots and repeats every few moments (a few days after her doing the system update)- if I remove the battery for a few minutes then put battery back and reboot it will boot into the OS where it will stay sometimes for a few minutes othertimes an hour or more before going into the bootloop- so I told her I would attempt to flash a new rom. after many hours of messing with the phone and attempting to access the recovery it just will not work- the phone just goes into the bootloop - exactly as mentioned above. I have used fastboot to flash new images (userdata, system, boot, recovery etc) numerous times and it still does the same thing- crashes and reboots into the bootloop from the OS randomly and bootloop when trying to access recovery. I am pretty sure it is a hardware issue (the phone is only 3 months old) but the company i bought the phone from is stating it is a software issue and not covered by tehir warranty.
Problem is I unlocked the bootloader while messing with the rom's yesterday and am now concerned they wont honour the warranty anyway- does anyone have any suggestions as to anything else I can try? As far as I can tell as I cannot access recovery I cannot install any other roms..
Please help- otherwise I will be posting a yourtube video of me destroying a basically brand new nexus one- I really am that frustrated....
a bit more info- it was rooted but still had locked bootloader when this started- rooted using onclickroot or something- which after the update it wasn't rooted anymore- I am wondering if this has caused some low level conflict somehow- I have rooted again using superoneclick - and as stated have unlocked the bootloader.
is there any way to flash a rom using fastboot or adb on this thing- I would hazard surely there is but amongst all the information floating around for this phone I cannot find out how- I am thinking maybe I try and load cyanogen 6 or something if I could work out how to flash a rom using adb (because njo matter how many times I try to flash different recovery images it wont boot into recovery- I can access fastboot etc but as soon as i select recovery I get the bootloop...
and before I get flamed I have spent three days searching and reading and attempting everything short of voodoo witch magic. I thought my X10 was a P.I.A. to root and flash etc but really it was simple compared to the trouble this phone has given me..
I am wondeirng if some of the rom's are incompatible with some hardware- and I don't quite understand the whole radio thing either... can someone explain that?
BTW Im not a total noob- I have been around for a while without an account - then have had this account for a while but mostly just read the forums as I have no real input and knowledge to give...
...help!
Can no one help?
I have managed to get into recovery (by putting the phone in the freezer for ten minutes at a time to reduce the temperature and stabilise it enough to run for 15-20 minutes at a time)...
Have flashed different kernels this way and nothing is stable- it still bootloops because of heat....
I contacted HTC Hong Kong (it was purchased from a Hong Kong company) and they have told me there is a $350 fee to repair it as its a UK phone. Now the phone is exactly 55 days old not three months and I am really really frustrated.
Does anyone know if its worth contacting HTC UK?
I have friends in the UK I can have them send it in and recieve it from repair....
Someone please help- even if its just a comment of "just smash the damn thing..."
Thanks guys sorry about the long self centred posts but I am ready to destroy this phone- it doesnt have a mark on it either- any ideas what its worth for spare parts?

Nexus - repair centre HTC

Hi,
I'm going to sent my Nexus one to the HTC repair centre, because he's been having this annoying random reboots.
My nexus has an unlocked bootloader, with a rooted custom rom. Is this going to be a problem for HTC? I mean, did I lost my warranty?
Because the problem is a hardware problem (I guess), so it has nothing to do with the custom rom...
Is there any possibility to lock the bootloader again and make the device look like how it looked when I bought it?
Thanks in advance!
are you sure this is a hardware problem? these kind of reboots are not uncommon with custom roms, have you tried chaing roms or kernels and seeing if that fixed it?

I've changed the kernels a few times. An I had the reboots on CM7 and on Miui.
Those roms are pretty stable I guess? And I haven't heard others complaining about reboots.
the reboots occur really randomly. Sometimes after a phone call, sometimes while browsing, sometimes while taking a picture. Sometimes I take my phone out of my pocket and it has rebooted, so I have to type in the PIN-code...
I tried factory reset and a clean install, with/without a2sd. with stock kernel, or with another kernel...
I don't know what to do anymore
After you flash any of these ROMs do your restore via titanium backup or similar because it happened to me once that every time I tried to open angry birds (weather it was normal seasons or beta) it would try to start then it would crash and it was no in the market and every time I would go to download it the phone would start the download then right before the install (when it hit 100%) it would go back to the cyanogen mod boot logo (I was running cyanogen obviously) so maybe it is something in your data that is screwing up and it keeps getting restored with titanium.
When you say a clean install, does this include MANUALLY wiping the /system partition?
Anyway, to your original question, unlocking your phone does void the warranty, that being said, HTC is usually good about replacing phones when it is a true hardware defect and keeping it as a warrantied repair. Most likely, when you get your phone back (if they don't replace it with a new one), it will be locked again with the stock OS on it.
But, your warranty is void, so HTC does not have any legal requirement to fix it under warranty. I am just telling you what I have noticed from other people's experiences.

Yes, I manually wipe everything.
Ok, thanks for the answer.
Since the warranty is void, does it still matter with which rom I give them the phone?
If they see a non-rooted stock rom, maybe they won't think the problem is caused by a custom rom?
Probably not. For any hardware problem, I'd bet the first thing they are going to do is flash a completely stock ROM to verify it isn't some software bug.
It is just easier than trying to troubleshoot. I don't even know how many of them would turn it on and let the phone boot up as that takes away a lot of time depending on how many phones they service in a day.
Hi!
I have the same problem and I could assure you guys that's a Hardware issue!!!
Probably the same as the HTC Desire!
From my personal experience I've sent my Nexus One 2 times and the assistance resend it to me simply reinstalling Froyo 2.2! I've sent the phone another time and, actually, I already have to do it back!
So, my Nexus is away since 2 months, counting all the 3 times!
I hope this time HTC have completely repaired my device. But still waiting for it...
NOTE:
I have an unlocked bootloader too, and you know that there's no way (actually) to re-lock the bootloader.
So the only thing that I do, before send the device to assistance, was to install the original Rom (Froyo or Gingerbread doesn't matter) and the original Recovery!
Obviously you must Wipe ALL (cache, partition, etc), to not encounter some kind of error's.
For the unlocked bootloader question, I don't think HTC void the warranty, because the Nexus One IS a Developer's Phone!!!
So it might be OPEN!
I'll post back later when I have my Nexus back with me.
Sincerely,
Matthew

While it is a developer phone, when you go to unlock the recovery, it does state that it voids your warranty. But I think HTC is decent enough to realize when it is a hardware issue that they are willing to still honor their warranty. I know a lot of people who got their power button repaired with unlocked bootloaders, because HTC knows it is a valid defect. BUT... they are not required to honor the warranty as it is void the minute you unlock your phone.
Where can I find the stock recovery?
I'm afraid this is also going to happen with my nexus, that they send him back, but the problem is still there. I'va read it happens to al lot of people :S
It's not even sure they can reproduce the problem. It's not like the phone is rebooting every 5 minutes...
about the reboots:
I've read a alot about it on the forums. And it seems that lots of android devices have this problem. Does anyone knows what might cause these reboots?
Maybe it has something to do with heat, which damages the motherboard?

Does your warranty center not support the advanced exchange? In the US, you can have them send you a new phone (while holding $520 of yours in reserve)... once you get the new phone, you send the old one back and they release your funds.
If you are that worried about it, I suppose you could just brick your phone yourself by screwing up a radio flash. That will prevent the phone from even booting, but I wouldn't/couldn't ever recommend doing this.
Tomorrow HTC is coming to pick my phone up
Hopefully they can fix the problem.
I've put the 2.3.4 OTA rom on the phone
Thanks for all the advice!

I guess.......and next time when you wanna root etc. just have the patience and read everything that is written here.
Never the less some phones are more durable in that matter ( i don't know why ). Some phones are like butter, 1st attempt and you are rooted. And with another you sweat like a pig and even then you can't do it right :laugh:
well
Well,
I hope it'll get better
thanx
Before bringing your phone to service you could try:
- a factory reset. Maybe the unsuccessfull rooting attempt has messed up something you can fix this way.
- flashing a RUU and see if the issue remains. This usually sorts out...

[Q] read from /dev/mmcblk0 failed

Hi,
I got my razr i about two weeks ago. Today, when i rebooted my phone i noticed that it takes a lot of time, eventually it got to Fastboot with lots of I/O errors.
Before i send it back for warranty, is there a change to recover with flashing the stock firmware?
I never unlocked the bootloader, so is flashing even possible? I'm very good with Linux, but this is my first Android phone, so i don't know how things work yet.

I have never seen an error like that before. I would send it to the warranty without taking risks like unlocking the bootloader.

[Q] HTC one M7 Maybe bricked?

Hello, I have flashed many HTC phones over the years and I have only bricked 3 of them well 2 I am not sure about this 3rd one. Getting to the point, I have an HTC one M7 that I flashed a firmware package to listed on a site called "Android revolution". The flash completed successfully and everything seemed to go like normal but when I rebooted the device after the successful flash it comes up in "Qualcomm USB Diagnostics mode (COM7)" and unlike other phones I have bricked in the past, this one doesn't come up as anything when you unplug the battery from the phones motherboard. Is this a Hardbrick? or no? and if not is there a way to make the device jump back to fastboot so I can try a working firmware that I have flashed to this phone in the past? Again I have flashed many phones and I have seen many bricked HTC from people and I bricked 2 of them last year and with all of those they come up as QLOAD_HS Downloader (COMxx) and they come up like that with or without the battery connected.

yup sounds like you bricked it, maybe its time to stop playing with your phones if this is the 3rd one, sounds like you flashed the wrong firmware, lucky for you this time, there is a fix as it was bricked by firmware :fingers-crossed::

I understand kind of what your saying but I must have flashed and unlocked more than 50 HTC one m7s and I never had any problems.
The first phone that bricked was an HTC amaze that I had and I even flashed that one many different ways and it always worked well but when I took it back to stock and S-On, it must have worked perfectly for about a month after that with no issues. One day that phone just froze up during a call and I had to pull the battery to unfreeze it and then it "for about a month after" started freezing like that sometimes more than twice a day. Finally one day the battery died and when I put it on the charger and turned it on, it froze up one last time at the HTC logo and remember, this was with no hacks or rooting back to stock and when it froze while turning it on this time, I pulled the battery and it never worked again. It was in qload_HS downloader and I tried the forum you are talking about and everything and I couldnt even get ubuntu to see the device.
So basically the only phone i legit bricked was an HTC rezound.
As for this one m7, I flashed that same firmware from HTConeguru many times but this last time I got a new laptop and HTConegurus site was down so I downloaded that supposed same firmware from android revolutions site and I didn't get any errors or issues but when it was done? and I typed "fastboot reboot-bootloader" its now comes up as "Qualcomm USB Diagnostics Mode (COM7) and a usb composite device with flash drive but I cant format the flash drive to actually use it. That is why I think there might be a chance for this one.
Thanks again
