[Q] [Help] Xperia T won't turn on, only vibrates - Sony Xperia T, TL, TX, V

Hello, before proceding to explain the problem I have to say a few things:
- the phone I'm gonna talk about is not mine YET, it's a faulty Xperia T I want to purchase if I find a 80% clear and cheap solution. This means I cannot try any idea you give me on it, 'cause I don't have it.
- I'm not a total noob in firmware and hardware fixes, but not yet an expert, so I'd appreciate a few explanations in the procedures you comment.
- I'm Spanish, so don't expect perfect texts from my posts
- sorry if a thread exactly like this is already solved, but I couldn't find any clear information about this problem on a Xperia device, so that's why I asked.
Now, the problem:
This Xperia T, as the owner explains, suddenly turned off and never woke up again. When he tries to turn it on it just vibrates, but no image displays. And when he plugs it on a red LED shows up (as if the phone was charging normally), but no more life signs.
Now, these are the fixes I would try:
- reset battery, because the owner is a normal user, and, as the battery is a "non-removable" piece, I don't think he tried to pull it off and on again.
- buy a new battery because this one could be damaged and non-functional.
- jtag is discarded because this happened in a stock rom, with no root, custom recovery, flashing or anything like that.
- get a new (or, at least, functional) motherboard, because this could be sudden death.
So now you could say "if you already know which could be the problem and the solution, then why you ask?". Well, what I'm searching for is opinions, what of those problems I mentioned has the highest likelihood to be the winner, because if you all guys think the most likely problem it could be it's the motherboard, then I won't purchase the phone, because motherboards are terrifically expensive.
So thanks in advance for reading all this

Does the red LED light stay lit up while charging? Maybe you'd want to google the "rubberband method"; it's for charging the phone when it can't charge on it's own while off.

Yes, the red LED keeps lit up. I've searched for that method and I'll try it if I purchase the phone, thank you so much
But what's your opinion about what the problem could be? Or which is the most likely?
EDIT: this is the thread I found about the rubberband trick http://forum.xda-developers.com/showthread.php?t=1849170, but is it called soft-bricked even when no firmware/modding stuff is involved?
RE-EDIT: ok, yes, even when no firmware/modding stuff is involved (lol)
RE-RE-EDIT: but still, if it's a hardware issue then all those tricks won't work, because there's physical damage, so that's why I asked for opinion x)

In my opinion, that behaviour is 90% due to a battery that is fried.
A broken battery is not able to supply the power needed for loading the kernel (that's why you don't see Sony logo and you can't recharge).
If you're lucky you can repair that phone with 15 euros for a new original battery.

ok guys, new information:
Apparently, the owner has way more knowledge about hardware repairing than I have, so we started talking about our ideas about all this thing and he said he already tried to reset battery, and he even replace it with a new one, so the fried-battery theory is discarded. Now I (we) think the problem could reside in the power IC, but that leads to a weld repairing, and I don't have the tools to deal with that.
So the thread is almost closed with this new info, but I still accept suggestions/opinions/ideas/whatever you wanna say, even if you enjoy typing the Macarena, at least we'll laugh with that xp

What I thought it might be was that the battery wasn't charged. It happened to me once, so I kept the power button pressed while connecting it and after a few hours I was able to use flashtool, and keep in mind that sometimes new batteries don't come charged.
But if that's not the case, then that method won't help you.

Tilt won't stay powered off

First off, I just want to say thanks for anyone who might be able to be of some assistance. I've tried searching google and the forums but haven't had any luck. If I've missed something, please feel free to hit me upside the head with the spoon.
I've recently been having problems with my Tilt regarding charging/battery issues. http://forum.xda-developers.com/showpost.php?p=2220715&postcount=37
Here's a quick rundown of my history...
- Can use Active Sync just fine
- When trying to charge, it says charging but won't charge
- No visible damage to the mini usb plug (at least to me)
- Had accident where the usb cable was pulled out from Tilt
Now...
I recently bought a charger that will just charge the battery separately from the phone until I can get it repaired. It's working fine so far except one issue. Whenever I try to power off the device (hold the power button till prompted to turn off), it'll power off then it'll power itself back on after 3 seconds. I did a hard reset to see if that would fix anything but it didn't. The only way to keep the phone off is to take out the battery. But once I put the battery back in, it'll power on by itself. The power button doesn't seem to be sticking or anything but I guess anything is possible. If anyone has any ideas I would appreciate it very much!!!
(I'm currently running the stock AT&T Rom without any programs installed. Also, I've never had any other Rom flashed on it.)

There is an option somewhere in power settings that enables/disables the Tilt from charging when connected to a PC. This may be the cause of the first issue.
However, the fact that it won't stay powered off...I have never heard of that before it sounds like a hardware issue. If your Tilt is still covered under warranty I would get it replaced.

Thanks for the reply! I tried adjusting that setting along with any other settings I could find regarding power but all without any luck.
I'm pretty sure it's a hardware issue as well, but I guess what I'm really wondering is if any one can make a semi-educated guess as to whether this could be involved with my mini usb plug issue or if the motherboard is just screwed
I'd love to send it in for a replacement but of course my warranty expired 5 days before the problems started

I'm not a hardware guru with HTC, although I have alot of experience troubleshooting PCs and Servers. I would say that it is unlikely that the USB port is what is causing the device to keep turning on.
In any event, are you qualified or ready to try an replace either one yourself (usb port or motherboard)?
There are 3rd party services that will fix the device...but they aren't cheap...it can cost $1-200 bucks or maybe more.
Are you running the Stock ROM/Radio/SPL? Or did you flash anything new?
You may want to revert everything back to defaults and see if the problem persists.

I'm handy with computer hardware and everything but not really with small electronics. I was willing to send it to a repair shop to have the usb plug replaced in hopes of fixing my charging problems but now I'm not sure if it'll be worth it if there's a bigger/more expensive problem.

I'm currently and always have been on the Stock Rom. I bought the phone as a refurb so who knows if someone here had it before me and flashed a bunch of roms . But since I've had it I've kept it running the stock AT&T rom. I also did a hard reset after I noticed the problem but it help anything.

Hmm..yeah...refurb doesn't sit well with me.
At least the problem isn't a crippling one...since you can charge it with a stand-alone charger. As far as not staying off....that's kind of annoying, but I don't generally turn my Tilt completely off. You can always just put all the power saving stuff on to cut down on battery.
So, it seems like something you may have to live with, or pay for repairs. Hopefully someone can offer a better miracle cure than those suggestions...

I was a little weary of buying a refurb at first, but it was actually in great condition and worked just fine until when I accidentally kicked the cable out of it. But thanks for the suggestions. And you're right, it's still very usable, just a bit more of a hassle right now. Hopefully someone out there has something for me.
Exact same problem as dieneverknowing. I am going to try some new batteries and see what happens.
- When trying to charge, it says charging but does not charge
- bought a charger that will just charge the battery separately - working fine so far except one issue.
- whenever I try to power off the device (hold the power button till prompted to turn off), it'll power off then it'll power itself back on after 3 seconds. I did a hard reset to see if that would fix anything but it didn't. The only way to keep the phone off is to take out the battery. But once I put the battery back in, it'll power on by itself.
im having the same issue on my old tilt. i took it apart. and still no luck . no visible damage, gonna clean everything and put it back together.
was this problem ever solved. sorry for bumping an old thread. But this is my same issue.
Hey don't worry about bumping an old thread. I meant to do the same when I got my phone fixed.
Turns out it was the sync connector that had damage. I sent it to PPC Techs for this service and it made it like new. I never tried to take it apart, but I could only assume that at some point in time, one of the pins in the connector became separated from the motherboard.
thats what it looks like to me. i have it narrowed down to the board with the usb connector. but not sure yet. How much was that service. i would replace it my self if i can find that part at frys today.
Service was $80, and then you had to pay shipping both ways. I had looked into replacing it myself, but my small electronic skills aren't good enough for me to risk it on a pricy phone. I remember seeing the connector part somewhere online for $40 I believe, but I can't remember where though.
But PPC Techs had it repaired in less then 24 hrs after receiving it. And they did a great job. It feels more solid then when I had originally bought the phone.

[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?

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

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.

[Q] HTC is bricked after battery discharge

Hi guys!
I've read lots of topic at this forum about this problem. This is my story:
I forgot to charge the battery, leaving 8%. The next day the phone was switched off. When I tried to switch it on appeared the battery symbol and the blinking red light. Then the phone fell and did not react to anything longer.
I tried different chargers to recharge it. Also via USB.
I also tried a combination of keys: power+volume button+light to sensors. Every combination.
What is important: the phone is NOT rooted. There is oryginal software.
Today I gave the phone to the service. And my question is: is there a chance to fix it without losing data? I pointed out that if they wanted to delete my data - that called me. But I want to know if it is at all physically possible to repair it without losing data? If yes - I will tell them that I don't want to repair it in their service and try to do it alone.
Thank you very much for advice!
I don't think they will repair it without wiping data
BTW your problem is quite strange, it wouldn't have to brick like this

Why do you think so?
If breaks down something with charging/power they usually change the entire motherboard, or perhaps only certain components?

if there are very important data you might want to discuss the situation with them carefully. If there are data that are more worth than your cellphone, then you might have to pay them a bit more that they make some kind of special repair.

Sudden death and...root !

My phone decided to not switch on any longer. The only sign of life is the notification led blinking red when is in charge, no way to access it with any program if I attach it to the PC with a USB cable.
I should send it to the Sony repairing center (still under warranty) but the phone is rooted; given its situation do they discover it ?
I had that exact problem. Turned out that the battery suddenly died after about a year.
In my experience they never care what stuff is currently on the phone. Instead they'll just flash it with the latest stock rom after fixing the hardware.
Thanks a lot for sharing your experience. I really hope will be the same in my case as well. I'll post here what will happen.
PS I'm wondering about the batteries' quality: my daughter with a z1c had your same problem (a little more than one year life), you, may be myself... I know the sample is not significant but...
Same thing happened with mine & i was on a custom rom with unlocked bootloader...they probably had no way to get into the phone just like i couldn't so they probably couldn't tell it was modified...it was just a brick at that point...i noticed certain batches were affected by this sudden death and after pulling my tag out i noticed my phone was part of that batch that was poorly assembled in china...so brand new phone for me!

OK, another positive experience. I cross my fingers and I'll post what will happen to me
I have the impression they dont even check the software, they just flash a new fw and thats it. Or they dont care.
My phone locked up on me like this, but I solved it by pushing a pin into the reset button hole.

Thanks for the suggestion but I tried any possible way to resurrect my phone, including what you're saying, without any result. I hope to confirm soon what all the contributors to this thread are saying...
Just received the device from assistance; everything went well: the motherboard was replaced.
The only drawback is that the lost the tiny grill that cover the mic at the bottom of the phone !!!!!

HELP! Mobile is keep turning off and then not turning on.

Hi,
First of all, Sorry for Bad English, Bear with me.
Long Story, Short!
It keeps happening!
It would turn off, won't reboot
Won't take charging
I will leave it for a while
If I leave it off after when I am tired trying to turn it on, a few hours later It will be WARM like it was being used, Then I would plugin again and THIS TIME IT WOULD TAKE CHARGE and EVEN REBOOT!!
After when I am using it for a while (10-12min) GOES BACK TO POINT 1
I ERASE EVERYTHING, FACTORY RESET IT, and This time.. IT would work for more than 10-12min,
I will install apps, login into the account, and then again... The same thing would start to happen! !
What Really Happen? Day ZERO!
I bought this Red Magic 3 phone 3 months ago and it was working super awesome and everything was great until last week after a 30-40 min gaming session on this phone, I went back to sleep and kept the phone on the table.
The next morning I noticed that the mobile is turned off, I thought Maybe battery drained so I plugged in to charge and continued with my morning routine.
After an hour I noticed that mobile is still not charging I tried plugging in and out multiple times and it didn't start charging, I checked the Data Cable on my MI MAX 2 (that also supports Type C) and Cable and Adapter were working fine.
I immediately realized that SOMETHING IS WRONG!!!
I saw some youtube video and I tried that Vol Key + Power Key thing and that Bios look alike menu opened up, I can see all the reboot, recovery boot, etc option but nothing worked.
So I picked the WIPE DATA option and It worked, Formatted the Phone and IT REBOOTED.
I figured maybe some software issue was causing it.
BUT SINCE THAT DAY it keeps happening!
It would turn off, won't reboot
Won't take charge when I plugin
I will leave it for a while
a few hours later It will be WARM like it was being used, Then I would plug in again and THIS TIME IT WOULD TAKE CHARGE and EVEN REBOOT!!
After when I am using it for a while (10-12min) GOES BACK TO POINT 1
Service Center
They are no help! They don't know what is wrong with it, Even they formatted it in front of me they did the Factory RESET it, I tried using it in Front of them for a while and the SAME THING HAPPENED!
then they installed some updates using some official package.
But still,
IT would work for more than 10-12min,
I will install apps, login in the account
suddenly... The same thing would start happening again!
Their Resolution is :
Motherboard issue and I will have to get the motherboard replaced.
This simply means EVEN THEY DON'T KNOW WHAT IS WRONG WITH IT and CHANGING EVERYTHING is their SOLUTION!
and they said it won't be covered on the warranty! Because the warranty has been voided BECAUSE THERE IS A SMALL CHIP on the phone! -_- which happens to be 40-50 days old.
I know is their Excuse to get money from me! Now I don't know what to do with it.
For me it was my first expensive mobile. I never bought a mobile for more than 200$.
Same thing for me.

What's your battery health at, voltage, and how many ma draw when just sitting in that app.
I've learned my lesson with this company. A couple of extra capacitative buttons and a large battery are not a reason to buy a phone. The build quality is ok, the software abysmal (I still get random **** getting pressed when I unlock the phone), and support horrendous. Do yourself a favor, threaten to speak with the governing authority in your country regarding warranties. Tell them a small crack on the screen is not indicative of internal damage. Tell them you will post a youtube review of the company and phone if they do not abide by their warranty and fix your phone.
Once you fix your phone, sell it and cut your losses.
When will people learn YouTube won't do anything. You need subscribers to have any kind of weight. I'm at 2.4m lol.
I don't know the warranty laws in your country. I know here they have to prove that what you did was the cause. Nubia is really shady and not only scams but will flat out lie all the time. I seen people had bad battery's and they say they need a replacement board.
Just let me know what I asked and we can start going in a little deeper. Start off with the basics then move into some other stuff. Could be a simple easy fix.
Some off topic posts are removed. Please remember our rules and post constructive content. Thank you.
Any update?
I'm curious to see if this is a battery issue or something else

I got the Battery Replaced thinking it was the issue but right after the installation. I turned it on to use it and it didn't work... I am still facing the same issue.. Meaning Battery was fine.. there is something else that causing it to turn off like this..!
Still, it acts like in COMA, then it heats up, I will charge it, It will boot.. If I will try using it ..it will turn off and won't turn back on!
