[Q] 1 Year In - want to throw cappy. Help??

History:
Bought Captivate 08/10. I'm on my 3rd phone, all replaced due to "sleeping death", capacitive buttons not working, some other common bug with this phone.
In May, I (and the captivate) was pushed in a swimming pool so my phone is no longer under warranty and I'm stuck with this thing. I actually tried to get it replaced at the AT&T service center and the guy was going to let me, but I had to get it back to stock firmware - I was running Paragon. The capacitive buttons are sometimes working, sometimes not so getting to stock fw was a challenge. I did that after several hours and returned to the store, but they voided the warranty due to water damage.
Present:
1. Capacitive buttons sometimes work. sometimes don't (days at a time)
2. USB will not work (I hate you for this Samsung). 2 cables, 3 pcs, drivers galore. I can charge off USB, but the PC doesn't see the phone and the phone doesn't see the PC.
3. Can no longer dl any apps from the Market - get unsuccessful message. Tried clearing cache of download manager, etc. as recommended on xda.
What can I do at this point? I'd like to install a decent ROM and recover as much as possible, but this thing blocks every attempt I make with some problem. I would replace it, but $600 is pretty steep for a phone right now.
Thanks

I'll offer what I can (I'm ready to give up on this $&@# device, too)
The buttons are flimsy as ****. They are just rubber inserts whos 'spring mechanism' is the rubber itself (to restore itself to its original shape). This isn't 'mechanical' its like expecting a seat cushion to always retain its shape (and not create ass divots). I suppose these extremely small rubber inserts could be replaced, but there is no mechanism to 'fix'.
**I'm assuming you meant the vol / power buttons (not the touchscreen buttons)
The USB thing.....I would get this sometimes. I found the BEST way around this (and this may not be a solution for you), but the market app "USB Cable" essentially sets your device up as an ftp location on whatever wireless you're on. Freaking golden if you're on your home wireless network, but if not, I doubt its much of an option (it is considerably faster than a 2.0 / 3.0 USB connection). **since you can't access Market (http://www.androidzoom.com/android_applications/productivity/wifi-ftp-box-free_vkuk.html)

One year in, then it's time for an early upgrade.

What do you expect after it being under water?
You can't blame samsung for usb or button problems, blame the water.
That said sell it and put the money towards another phone.

By any chance did you buy the insurance? If you did, just call it in lost and pay the $125 deductible and have a working phone. If not there's really not that much you can do. What did you do to dry the device out? believe it or not, there may still be moisture in there. You might try putting the phone in a container of some sort and covering it with rice (uncooked of course) and letting it sit for a day or two, and then try it out.

I would blame the jerk that pushed you in the pool, not the phone....That person owes you a phone.
If you've been running stock 2.1 or 2.2 the poor performance will happen.
I felt the same way about the phone until I discovered the cognition rom, it's well known for being very stable but with your usb issues...good luck.

thanks for the advice everyone. i will check on the insurance route.
but yes, i can blame samsung for the usb issues. why is it so difficult to access your phone via the built in usb port? special drivers, distinct cables, etc. are absurd.

How many phones don't use some sort of drivers to get this kind of access to it? I know the majority of the phones I have used in the past have needed some sort of drivers. Also, what distinct cables? It's a micro USB, you can't get any more common for a modern device than that. Samsung uses excellent hardware in everything they build and they regained my respect from the Froyo flop when they leaked Gingerbread so quickly to realistically a fairly old device. On top of that, they also leave their hardware to be hacked by our skilled developers (unlike Motorola).

He didn't mention this issue specifically, but even when using the correct cable/drivers you can still get the dreaded adb offline error. Sometimes changing usb port fixes the issue. This screams bug, either in the samsung drivers or maybe adb itself?

What "special drivers" would he be talking about then? I'm just one of the lucky ones that got a phone that works, 3 button works, adb always works, never had USB problems, never bricked (yet).

Possibly because you submerged the phone in water?

Welcome to the world of smartphones.
thread closed

Regarding a possibly bricked phone.

Two nights ago I was watching a video through the YouTube app when suddenly the screen froze up. When it stayed unresponsive for 5 minutes or so, I shut it off by holding the power button down, which seemed to have worked as intended. After that it's become absolutely unresponsive. It will not boot up or turn on whatsoever, nor will the LED light up when plugged into a wall to charge.
The phone was running CM7 and had CWM as recovery, but I'm absolutely stumped as to why it fails to boot up. Has my phone decided to spontaneously brick itself? Is it potentially a hardware fault? Any suggestions would be appreciated. I'll be taking it to a repair center tomorrow, since I've really no choice as of right now.

Yea not really much else you can do besides taking it in for repairs. Maybe remove battery for an hour, although from the sounds of it, it won't do anything.

Doesn't seem to work. However an interesting observation, when plugged into the PC, it's detected as QHSUSB_DLOAD. Is it possible my phone's entered some sort of low-level mode? And if that's the case, is there any way to reverse this? I say I held the power button down and it shut off but I may have hit the volume keys in my panic.
So yes, I remain hopeful there's some miracle that will let me get out of this mess.

This interests me too, I'll be researching all the info I can find, although the first search on qhsusb_dload has come up with a lot of questions and no answers as yet.
Many threads have blamed partitioning the sdcard in cwm recovery as the cause of this.
Did you manage to get any drivers for this qhsusb_dload mode?
Edit: these might be useful. http://www.x-drivers.com/catalog/flash/mobile_phones/companies/qualcomm/models/qpst/12051.html http://forum.xda-developers.com/showpost.php?p=14909282&postcount=19

Yeah, I've tried out the QPST software and drivers and believe it or not, an answer to my fears. My phone has entered Download Mode with seemingly no way to exit it. I can't find any posts about this in regards to the Incredible S. I guess nobody's been careless or unlucky enough to get it to this state. See the attached picture. Also I can't help but note all the question about ENTERING download mode as opposed to EXITING download mode. Is it so simple that my brain simply can't comprehend the answer?

unfortunately, its not a simple answer. Probably the best thread concerning this issue is in the sensation forum http://forum.xda-developers.com/showthread.php?t=1468791

A dead-end unfortunately. It seems more like a preventative measure than anything. I can't enter diag mode on account of phone being stuck in download mode. I'd like to believe it's hardware related. Anyway, I believe it's time I called the repair centre. I appreciate the help you've given me.
EDIT: Seems like Fonebiz refuses to repair my phone, warranty or no, as it's an overseas model, (even though it's physically the exact same phone, down to the model S710e) short of sending it overseas. Unbelievable. I think I'll go cry in a corner now.
EDIT2: Gave it to a local shop to send for repair. I'll let them figure it out. If anybody has any information on proper use of the Qualcomm Software Download tool, by all means link to me.

Samsung Galaxy S3 suddenly dies and won't turn on even after battery removal

The phone was plugged in to my computer (I was doing development) and was running all the time. Suddenly, while I was not doing development or doing anything, the phone died and I have have never been able to turn it on again.
I've tried:
Hold the Power button
Hold both Power and Volume down button
Take out the battery and put it in again
Replace the batter with another one from my friends' working-perfectly-fine Galaxy S3
The result is the same: no response from the phone at all - it's completely cold, no sound, light or vibration at all - all I've seen is the blank unchanged screen so please don't ask me about the start up screen
What can I do?
*Notes: I've read this thread but my warranty has ran out so bringing it to Samsung is not really the best option.

Recovery mode download mode ???
Usb Recovery Jig to access download mode ,

As mentioned, I have already tried holding the Power button and the Volume Down button so no recovery mode for me

That does not get either recovery or download mode and is the reason i posted .
Recovery Vol UP + Home + PWR
Download Mode Vol Down + Home + PWR
Suggest you read the basics faqs and guides first .

Same problem
Did this ever get sorted? Mine is doing the same.
Won't power on whatever I try.

As the OP never posted again suggest you take it to a service centre .
Try reading the sudden death syndrome post.

Hi all, I eventually had to take my phone to a service for replacement of the phone's mainboard. The mainboard was the problem and now the phone is ok again.
Thanks everyone

If you are going to replacet the motherboard and use the same phone, your data should still be there.
If you are going to use a new phone, you have to take out the hard drive and connect to it to get the data from there.

There is no hard drive in the Galaxy S3, just an eMMC flash chip soldered to the motherboard.

Are you sure all people on this forum are developers? Also, just what kind of developers?
Again, my answer could be wrong but how can it cause problem for others?
Let's break it down:
I said data should not be lost after motherboard replacement
There is no action required here so how can it lead to anything harmful?
Last time I checked, the data in my S3 was still there after its motherboard was replace
Taking out the hard drive from the phone was the part I wasn't sure
As of now, I can see that it's apparently wrong as someone pointed out
However, if there is no hard drive ==> how can one take it out ==> how can one damage anything?
How can I be responsible for anything here?
What do say now Mr. smart developer?
Please provide something concrete and convincing.
Don't waste your time, don't waste mine

After checking my hard brick phone by a bestbuy technical, i was told my phone was totally dead. The phone wouldnt connect to PC, can't do power charge, no any response even the jig method. And the data is gone. However, I am not sure how the data backup works. maybe they just don't wanna do it or their lack of doing it.
Normally, the data recovery from damaged hardware is expensive. cause it need plenty of time and they probably think the customer wouldn't pay for that.
Directly replace a motherboard could cost less than repair it. In some cases, could even replace a new phone cost less than a new motherboard. Technically, backup data from hard brick phone could be possible.

Similar problem with my Samsung Galaxy S3. Mine turned off randomly and wouldn't turn on again for half a day each time. The last time it happened it wouldn't turn on for a day, so I tried the DOWNLOAD MODE combination, cancelled it, got prompted to RESTART PHONE then it turned on again.
I took in my phone directly to Samsung Customer Service in Albany, Auckland (for New Zealand people). They found that the "current was not stable" and all they had to do was replace the mainboard. It only took them half a day to repair and it was covered by warranty. He said the cost of the mainboard, outside of warranty, would cost around NZD $260.
Replacing mainboard shouldn't affect your memory but it is always best to back up your phone via Samsung Kies (or something similar) before taking it in for repair. According to the Samsung guy, in New Zealand, they are not legally allowed to back up a customer's data on any of their computers, but there is no harm in asking them if you trust them to do so.
Hope this helps

Replacing the main board replaces all data except the External SD-Card, as the EMMC is built onto the motherboard, they can always backup the /data over QPST, where it isn't readable by any program except that one.

If you replace the motherboard you are going to lose all your information. All the information its in the old motherboard so there is no way to save your data if your motherboard is replaced.

[Q] Hard Brick (QDL) Solution Research - HTC One (M7)

Hello XDA-Forum,
i am new here, so you dont know me. Therefore i have to mention at least one thing about me: I never ask for help. Especially not regarding electronic Devices and Computer Systems. I always found my answers without asking.
Now i do ask for help. Do the math, its a serious problem . As i am used to solve my problems before asking for help, i have much to tell before anyone could add to what i already know about this problem (although i have to admit that i am pretty new to the Smartphone World). And as sure as i know that no one here wants to read another "Phone broken, HELP!" Thread, so sure i know that not everyone has the time or patience to read my ramblings (i actually wrote a rant too, but decided not to include it here ). So i prepared a summary, and you can see at a glance (almost) if you could help me at all.
Short Story:
My HTC One is Hard Bricked, and beyond my ability to repair - stuck in QHSUSB_DLOAD mode, no access to partitions, no booting under dead screen. It seems i have to send it in for repairs, but i dont like that(well who does?). I researched the problem, tried every solution i could find - no result! if you happen to know a solution, please read the long story to learn what i have tried so far, and if your solution is something completely new (something i didnt try) - PLEASE tell me ASAP before i send it in for repairs.
So, i tried everything i know of and came to the conclusion: it is beyond repair, at least for me. But as this is against everything i believe in (well not everything but i hope you get the point ) i want to find some other Solution if not for me ( as i need my Phone to be working again soon) then at least for the next one facing the same problem. Again: read the long story, or at least the last part, to know what i am asking for... Basically i want to collect all information regarding this problem and find a solution if possible.
Oh and i would prefer technical answers (even if i might have to learn more to understand them) over answers that suggest "Dont bother, you are a noob, you wouldnt understand, just send it in". If you are about to give such an answer, rethink and do something else .
Long Story (Part 1 - What happened):
31/12/2013: My HTC One suddenly stopped working. Until then it worked just fine since i bought it in July 2013. It happened without any apparent cause or any hint of what went wrong, during everyday use, no water involved, no falling, nothing that i could identify as cause. I pressed the power button to wake the phone as always - but the screen stayed black. At first i thought the battery could be empty, but i checked it only 5 minutes before, and it said 32%... still i thought the power indicator could be buggy. Since then it never showed any lifesign again though. It wont start, it wont charge.
I researched about this, and it seems that others had the same problem, and on several different devices. I think i found almost every Qualcomm based device, but mostly the problem was caused by flashing, so this can not be the same problem. If i remember correct, i found HTC One, HTC One S, HTC Desire C, HTC Sensation, Nexus 4/7, Samsung Galaxy S3/S4 and maybe some more, with the same issue i have - Device suddenly went black and got stuck in QHSUSB_DLOAD mode without apparent cause. Many people get at least a lifesign from the LED tough ( be it blinking occasionally, or staying on all the time, or blinking after pressing certain buttons) - i dont.
Long Story (Part 2 - What i tried):
I found several tips on how to revive a device in this state, most recommending something like "press power and one(or both) volume button(s) for XX seconds/minutes" sometimes with the addition to do this under a bright light bulb.
I tried holding the power button, power + vol. down, power + vol. up, power + vol. up + vol. down, for {10,20,30 seconds, or 1,1.5,2,3,5,10 minutes} (countless times), and the same under a light bulb (i doubt this makes any difference as i already did some resets previously, outside in pitch black darkness long before the phone died).
Some recommended to plug it in to charge and dont touch it for 3,8,12 hours - i did that. i tried charging with wall plug and via USB at laptop (for short periods and for 1,3,4,6,8,12,18 hours without touching it).
At the moment i try to leave it off the charger for some days (the weekend and probably some days after) hoping that it will eventually loose all charge and does some sort of reset after that. I doubt it will work, or even be enough time for discharging (as i doubt that it actually USES power in this state) but dont know what else to try before sending it in.
The charging-led stays off when plugged in and there is no response at all from the device. Except when i plug it in at the laptop, Windows recognizes it as QHSUSB_DLOAD. And under Linux i get the Qualcomm device too - no partitions though. If i press power for 10 seconds while connected, it reconnects - so the power button is working. QPST recognizes it as "Q/QCP-XXX (Download)". Is this normal or should it recognize the phone model even in download mode? I tried to get some information through QPST but it tells me the phone needs to be in DIAG mode - which i obviously cant activate on the phone itself. Other than that no life sign at all( also no recognition by adb and fastboot - so its not booting under a dead screen as someone suggested somewhere - dont remember where).
Everyone who had gone as far as i did in trying to revive the phone just gets this last answer "JTAG, or send it in for repair".
Long Story (Part 3 - What i learned):
As i understand it, the Qualcomm Processor switches to this state (QHSUSB_DLOAD) in case there is a severe problem. But i want to know exactly WHAT problem can cause this? And if there is ANY way of convincing the processor to switch to some other state without opening the device?
I dont know JTAG, i never heard of it before this research, so please correct me if i am wrong, i did just a brief research on JTAG and found it too complex to grasp in one or two days i will delve into it at a later time. Here is my first few-minutes-glance at JTAG: it is some sort of standardized hardware-debugging protocol built into many chips, and also the Mainboard or Processor or both in modern Smartphones and Tablets. One would need to open the device and solder the connection cables of a "JTAG-Box" to specific contacts on the Phones Mainboard, is that right? or is there a plug? (I think i found some people using a plug and some using solder iron... i dont remember properly.) When a JTAG-Box is connected to a JTAG-enabled chip, it can issue debugging-commands and/or queries to check (and/or modify?) the functionality of the chip. I found some mentions of JTAG via USB without explanation, is this a way to issue JTAG commands without JTAG-Box over USB Cable? (would be very convenient) Or is it just a way to connect the JTAG-Box via USB to the Computer?
You might ask, if i researched it, i should have every answer, so why am i posting this? Right, i got SOME answers. Now, i know...:
1) ... that am not the first one, nor the only one with this particular Problem. And not even my phone model is the only device with this problem. It might be, all Qualcomm powered devices are possible candidates for a sudden-brick-syndrome.
2) ... some ways to revive a Phone in this state (none working for mine).
3) ... if all reviving tricks fail - JTAG or Repair-service.
4) ... that JTAG needs an opened device (or does it? JTAG via USB maybe?)
5) ... that my phone is not entirely dead: at least the processor can still (sort of) communicate with the PC in Qualcomm High Speed USB - DownLOAD mode.
6) ... no one knows (or tells) what the cause is (or could be) for this problem. The only answers i got are: "There are many possible causes." and "It could be a Software problem" (HTC Support) and finaly "No one can tell without analyzing the device" (HTC and Carrier Support) - Sure no one can definitely tell what EXACTLY is wrong with THIS device... but someone could know what COULD be wrong (What the KNOWN causes are), and just tell me.
Long Story (Part 4 - What i want to know):
Well... I could(/should?) just give in and send my phone in for repairs and hope for warranty. But i did unlock the bootloader through HTCDev (had no other option for unlocking due to HBOOT 1.44) and suspect, they might use this fact to refuse warranty and charge me for repairs, which i might not be able to afford right now. Further, i am feeling absolutely helpless in doing so, and i am NOT used to feel helpless facing ANY sort of problem with ANY electronic device! It is NOT a nice feeling! And i want to change that! Even if it will be too late for me, as i have to get my phone back soon and will probably send it in this week for that reason, i want to find a Solution, that anyone could use to solve this Problem without even contacting the Service, if it is possible to find such a Solution. That is the reason i am posting this, and here is what i want to know:
1) EVERY Story about devices stuck in QHSUSB_DLOAD mode.
1a) IF they where revived and HOW.
1b) What was the cause?
1c) If they could not be revived...
- ... and had to be replaced by a new device: what did the repair team tell what exactly was broken? if they told you anything at all.
- ... and needed replacing parts: WHAT parts where replaced?
- ... ANY hint of what caused the defect?​
1d) WHEN did it happen? (while flashing seems to be the most common scenario, but i and some others had it happen during everyday use)​
2) What exactly is possible to do in QHSUSB_DLOAD mode (probably using QPST)? and what isnt? f.e.:
2a) Pulling any data from the phone without switching to DIAG mode?
2b) Getting ANY information about the phone? (IMEI,CID, etc... Hardware components - i guess it would need a switch to DIAG mode?)
2c) Switching to DIAG(or any other) mode ONLY using the PC and USB connection? (if possible, how?)
2d) Pushing any Data to the device
As i understand it, that is the purpose of this mode(is that correct?), but:
2e) What data can be pushed? Bootloader? System Image? .... i think some CPU firmware is delivered with QPST, correct?
2f) Is it possible to convert an existing System Backup so that it can be flashed with QPST? (i understand QPST needs files in IntelHEX format to push them? Or is that just the CPU Firmware?)
2g) QPST recognizes my phone as "Q/QCP-XXX (Download)". Is this normal or should it recognize the phone model even in download mode?​
3a) If i get no Partitions in Linux while the QHSUSB_DLOAD device is recognized, could this be an indicator for an Hardware failure?
3b) Does it mean, at least the flash memory is fried? (my guess)
3c) Could i tell if the Mainboard was fried by NOT even getting a QHSUSB_DLOAD device? Or can it still be the Mainboard?
3d) Can i tell anything from these facts (Getting QHSUSB_DLOAD device recognized but no partitions)? other than "its a hard burned brick" obviously...​
4a) Which kind of HARDWARE failure could create this state?
4b) and how could that happen during normal use in a device that is only 6 months old, and in good condition?​ 5a) What kind of SOFTWARE failure could cause it?
5b) while it is running? (every day use / not flashing)​ 6) IF i send it in:
6a) Will they be able to access my data?
6b) Can they tell (by JTAG maybe) if it was rooted,flashed, had an unlocked bootloader?
6c) And the hardware is dead, will they just replace the fried parts? or replace the Phone with a new one? (not really important but nice to know )​
7a) Is it possible to use ANY type of JTAG commands/queries/(whateveritiscalled) WITHOUT opening the device? (via USB)
7b) Without a JTAG-Box? (already existing software simulating a JTAG-Box)​ 8) What kind of Information can be gathered by JTAG? f.e.:
8a) Working state of hardware components?
8b) Access to files on flash memory?​ 9) What kind of modifications/commands can be made/issued by JTAG? (depends on the device/chip attached i assume?)
I know i could just buy a JTAG-Box and learn everything about JTAG to answer some of these questions myself. But i did not find time for learning about something completely new (new for me) yet, and i dont have the money at the moment to just buy a JTAG-Box without knowing how to, and if i will use it (dont even know how much it is...). I will certainly NOT open my 660€ phone, probably breaking the screen and whatever in the process, because of its DONT-OPEN-ME-Design(nice looking, but in some cases inconvenient), and make it a test-dummy for my first JTAGing steps. So it would be nice if someone with some experience in that matter, could give me a brief overview of the possibilities and uses of a JTAG-Box - AND if there is some way to simulate one.
And finally i would like to get into contact with people who might have a clue of the possible causes for this problem, and the ability and willingness to work on a solution. I did find some WIP Unbricking Projects also working on a solution for QHSUSB_DLOAD related issues, but all of them where Model-specific (and mostly for cases where a specific flashed software was the cause) and none for the HTC One (M7)... Although i would like to have a general solution for every device and cause, i doubt there would be any Model-specific Project if it was POSSIBLE at the moment to provide a general one. It would be nice though, if we could at least TRY to make one(some people probably are already trying). But i assume (from what i read) that the existing unbricking projects still need access to the internal storage. So, no access to storage = hardwarefailure & not unbrickable by software?? Even if thats the case and my phone is realy beyond (sofware)repair, i would still like to get answers to my other questions!
If you did read all of this - Congratulations! Have a coffee and a break
I am sorry for:
- noob questions (if there are any left besides the JTAG related - i cant tell anymore)
- annotations and supplements in braces (it can be annoying, i always squeeze in some thoughts somewhere)
- forcing you to read this wall of text, probably full of spelling and grammar errors (i am tired and somewhat tense)
- bad English (not my native language, and... i am tired)

OMG this post is incredibly long. I'll give you a short answer.
Yout phone is hard bricked and MAYBE a JTAG may fix it, BUT the phone needs to be opened, which with this phone is pratically impossible to be done, furthermore you need smb with experience on those things.
If you weren't soing anything to your phone(s-off, hboot flash, ruu, etc) than probably the motherboard is dead. I have seen this happen a lot of times with this phone, probably because of not genuine charger/faulty. You SHOULD sebd your device for repair definitely, I'm 99.9% sure no one will notice it's HTC dev unlocked, cause it doesn't turn on. A lot of users have sent their and had no problems. Good luck!

Well, the phone is (was) s-off, rooted, and running ARHD 40.3 + TWRP 2.6.3.3 - but i did this long before it died and never had problems during the process, or while using the device.

I mostly used the HTC plug which came with the phone for charging. Although i didnt use the original cable, because it broke shortly after i got it. Sometimes i used a USB-Battery-Pack to charge the phone on-the-go. Could any of this be the Cause?

So, they cant just JTAG it (or do something similar) and it will turn on again? Obviously not if the motherboard is fried... but is it possible that it isnt, and they can? I will send it in nontheless, but i would like to understand what is possible, and find the cause aswell as a solution.
oh and thank you!

Hi, just wondering if you had any updates to your story?
I have a HTC One in basically the same situation - it totally died on my wife in the middle of her using it. The battery was at over 50% and we have never even dev unlocked it or flashed ROMs or recovery etc. No lights come on when charging, tried all manner of the power, power+vol key combos etc, tried the bright light as well, nothing gets it to come alive. Plugging into the computer does recognise the HSUSB_DLOAD low level qualcomm device but as yet I havent been able to get drivers to allow it to be recognised. I am taking it to a place on the weekend that says they have JTAG box and may be able to help. I would send it away for warranty replacement but it's my wife's phone and she hadnt backed up the photos on it for a few months and we have a 20 month old son, so we are trying everything possible to retrieve the data off it. Lesson learned, will be putting in place backup regime on our phones from now on!
Will let you know if any joy comes from the JTAG process
Reading your recent comments it is interesting to note that we do have an external power brick (IO Gear 11,000 mAH unit) that we sometimes have charged the phone on. Potentially we even used the 2.1A output from this power brick rather than the 1.0A output on occasion.

Sorry, i totally forgot about this Thread over all the other things in the last weeks (Starting a Business, moving to a new Place.. etc).

Yes, i sent it in for repairs, and got it back two weeks later. They had to replace the Mainboard and some other Parts(plus some they broke during Repairs), i could not get any information about the possible causes other than "there are many"... It was covered by the warranty though.
I dont think they could get any data from the Phone.

If the cause is indeed the power brick, i will have to check mine again (measure its output). It is supposed to have 5.0V 1.0A output only, which is the same that the HTC Charger is labeled with.
Well, good luck with your Phone! But if your Phone is as dead as mine, i am afraid you probably wont get those Photos back...

Ok, i got my phone back without trouble - but i am still researching (when i have got the time ) the causes and a possible solution for this problem. So, if anyone has any information that could be helpful: please post it here!

Hi guys! Sorry for my bad english but i'm italian. My HTC One gone in QHSUSB_DLOAD mode 3 times (it's not a joke) and i've still it in my hands
This is my configuration now: (today my phone entered in QHSUSB_DLOAD mode)
Firmware = 4.19.401.8 (Darkbootoader)
ROM = SkyDragon v12.0
Kernel = ElementalX 13.0
PVS = 5
Today when tried to turn on the screen with doble tap it do nothing, screen was completly black and same thing when i hold the power button with vol down. After i plug in USB (it was a normal nokia cable) cable and hold power + vol. down for about 20 seconds (there wasn't LED or blinking button, anything) it's boot into bootloader:highfive:
I suppose (because every time my phone bricks when i do too Undervolting) it has "hangry" of energy and it boots up anymore if i don't give him an "help". The same thing when i had the MIUI with the same undervolting
Maybe is too much Undervolting the reason of hard brick, did you undervolt your CPU like me?

Did you find out any answer?
Where you able to bring it back to life?
Did you send it back to HTC for repairs? How did it go?

Would this work?

third time.

To make a long story short (like you did in the OP), I have to same problem
The cause: flashing newer firmware version. All the symptoms are exactly the same. When I get home from work today I will try these 2 things, they are a little variation of what I already tried:

http://www.androidlegend.com/how-to-use-adb-fastboot-commands-with-your-android-device/
I don't have much hope that I can fix it myself and am already in contact with HTC though. The main problem is that I'm in Argentina and I bought the phone in Germany..
You didn't find any other possible fixes, right?

Hi, I Have Same Problem Since A Month With My HTC One M7 32GB
I Got this phone as a Gift From USA HTC one M7. My Phone Just got hanged on lockscreen when i try to restart it, it turns off but did not turn on,no single light is turning on, no screen light or notification, no recovery or download mode. its like a brick piece. i tried all charging tricks such as USB PC ,Wall Charger for Hours, Orignal Charger and rest things, i cannot send phone to USA , i am in qatar, what should i do, any guys who experienced such problem and how did they solved it and, what will be the cost if no warranty. any help ? thanks in advance. :crying:

Hi, how did this go? I just bricked mine doing the same thing... upgrading firmware. I can't get it to respond to any of the suggested methods. What sucks is that the firmware update dialog in fastboot looked good to me. Sucks...

Cool, thanks! I wonder if a vm running linux would work. All my machines are windows. Not sure how the vm would handle the usb connection. I'll have to see what I can figure out.

Yes! I just thought of that after I posted. I think I still have an ubuntu live CD around here somewhere...
Thanks!

I'll be damned! This worked! I just popped in the latest Ubuntu liveCD and went to town. My phone is now up and charging. Once it's at 100%, I'll try pushing TWRP recovery to it and restoring my last backup.
Thanks again for sending me to that link!
---------- Post added at 10:42 AM ---------- Previous post was at 09:59 AM ----------
Done and done... pushed TWRP and restored my last backup. It's as if it were never bricked! And it also updated my kernel, which is what I was trying to do in the first place.

Just for future reference for anyone coming across this thread, there are two distinct types of bricks being discussed here.
The first results from a borked firmware update. In this case, everything works on the hardware side, it's just that the phone can't boot because the firmware is messed up. This is usually fixable using Dexter's method.
The second, and the problem experienced by the OP, is more serious and is hardware related. I have seen this occur with multiple HTC models. Something related to power management on the motherboard dies so that the phone no longer can no longer get power to start up. When this happens, the phone will typically have shut down without warning despite having a good battery charge. I have never seen or heard of a fix for it beyond returning it for warranty repair.

hi i have a problem when usin my phone it suddenly freezers and was not able to get acces to anything (Was rooted/Bootloader Unlocked/having Custom Rom/TRWP/S-ON).. tried to restore my rom by usin twrp 2.8. but there was no file and it cannot mount my storage...
Then, found on a thread to restore stock ROM via RUU, so i relocked my bootloader and then find myself stuck at everything
When I plug in AC adapter for charging, phone load in bootloader, and whenever i press "Fastboot/Factory Reset" my phone freezes
Even fastboot and ADB command freezes my phone,
I need help please.

Help, my XZ1 C was dead?

Hi!
Please help me!
I installed custom ROM(no SeLinux support) and tested two partitioning programs.
ROEHSOFT PARTITION TOOL
and
ROEHSOFT DRIVE-EXPERT
I did a partition recovery and reboot the phone.
Since then, it doesn't turn on, doesn't charge, no led feedback, can't see the pc, and no fastboot mode, completely dead.
I disassembled, disconnected the battery, but nothing happened.
Died?
What can you do with it even if your PC can't see it?
The two partition programs, in stock rom, did not start, but this rom (selinux is inactive) was ran.
What happened to him being completely dead?
THX

Obvious question, have you made sure it’s turned off before you try to boot it? The screen might just be black but the unit still on.
Hold down Vol up (+) and power together until the phone vibrates three times. Wait a couple of seconds, then press the power button once to try and start it.
As long as the screen wakes up, then you’re in with a chance of getting PC Companion or Flashtool to see it and rescue it.
This was an unlocked phone? If no, then there's a slim chance that you haven't done any permenent damage and you might be able to re-flash.
If you don’t get any joy from a reset, then you have rodgered your partition table and there isn’t any way to bring it back from that.

@dustinzahn, in my opinion, changing partition is very risky. Most likely it is a brick already, no way to recover, if it does not enter fastboot nor sony flash mode.

RIP

Hi Guys!
Thanx the answers.
BUT...
XZ1 C doesn't have a testpoint like Z1?
https://forum.xda-developers.com/showthread.php?t=2682255&page=13

THX!
Yes, unlocked, but hiding J4nn-s kernel, OEM closed the menu.
I tried everything.
It doesn't vibrate, can't detect the PC.
In old xperia's, touching testpoint fixed this and entered fastboot.
I can't find a testpoint on this.

Hi!
This picture is low quality, but the f*ucking Ilike phone's camera is ****.

Do you know the IMEI number?
You could register the phone on the Sony Warranty site , then call the helpdesk and say it's stopped working.
You might be required to provide some proof of purchase, but if it's within two years of its original sale, then it's covered by warranty (EU &UK).
Don't worry if you didn't buy it new, the warranty moves with the phone, not the purchaser. If it was sold through a service provider, putting the IMEI number in will tell you when it was origally sold and what, if any, warraty is left.
Edit: might be a bit late if you've pulled it apart

Sorry, I thought they had posted pics of an Z1C. Unless there is anything under those heat shield things you might be out of luck.

These are much better pictures, I removed the battery, there are a few testpoint candidates.
The battery was glued and not easy to remove.

And the results of your testing?

I give up.
Sorry, my English is not very good, I use the google translator, I'm trying to be understandable.
Stupid Sony designed the motherboard that the test point section right on the bottom half. The phone must be disassembled from the display side.
It's almost impossible to press the test point and while using the usb.
I also broke the flex cable, and I was tired and irritated, so the display cable also damaged.
I tried all the existing "test points" , but nothing happened. He probably didn't survive the procedure.
If the motherboard is good, the display and the USB flex replacement is almost a used XZ1C price, so it landed in the drawer. It'll be good for decoration.
But I found my first smartphone, a sony ERICSSON Mt15i, Neo.
I was originally a Sony Ericcson fan.
The touch screen is bad, but I've already assigned it.
I have a z1 compact, there's the power + volume flex cable must replace, I also ordered it.
Neo now works with an OTG + mouse, but the Z1 Compact does not turn on without a button, only indicates charging.
The Hungarian Sony support was big ****, and the Hungarian warranty service doesn't want to help, even though I told them it's the phone no longer a warranty, all I'm asking is that you help me identify the test point.
But no, they're just indoctrinate me, and they think it can only be repaired by replacing a motherboard.
Yesterday I bought a Xiaomi MI Note 10 phone. It's awesome.
I hope the russel5's [Treble/Pie/XZ1c] crDroid will be there as well.
I liked this ROM, but the disabled SeLinux is a big problem, I think the problematic apk is because of what killed the phone. The STOCK and [Treble/Pie/XZ1c] AOSP Extended ROM did not start the apk, even though i gave him root right.
I think the CrDroid ROM's disabled SeLinux let it run.
Maybe the apk was infected, but I use Malwerbyte and Kaspersky.
The Apk name is ROEHSOFT PARTITION TOOL SD-USB and I download from the Aptoide.
I know I'm a ****ing idiot.
Partition program should not have been downloaded from there.
