[Q] DHD brick and guarantee help

Hi Everyone !
I have a Desire HD and it bricked last sunday evening. It's only half year old, so I took it back to T-Mobile (I bought it from them). But it's rooted and Radio S-OFF-ed when died. Can the service establish that I rooted and S-OFF-ed my phone, or no ?
Thanks in advance !

If it's totally dead (no bootloader access or charge light) then they won't be able to tell. They'll fix it without any knowledge of software changes.

Yep if its completely dead they wont bother repairing it, they'll just replace the motherboard. That way they have no knowledge of what you did to it.

Thanks for the answers,I'm happy right now,because you have the point:absolutely no sign of life. No charging light,no bootloader and no any happening when I press the power button (same with another battery too).

how did you manage to do that? It will be good for others to know so that they dont make such a mistake .

I don't know. Here's what happened:
1.: I use Opera Mobile for web browsing and the past few days it's become very slow. Sometimes the only way to close it is press the Home button and close it in task manager. I thought it's a software problem, so I made a hard reset, but it's not resolved my problem. Mean while I saw the news that HTC will not refresh the Desire HD to ICS in the first line, so I downgraded it and flash the latest NDT MIUI ROM.
2.: Next day I connected my phone to my PC and realised there is no communication between, only charging. I tried it in other computers and other USB cables, same result, so I wanted to back to stock. My only problem was the Radio system. I was still S-OFF-ed. I searched so many forums and I tried to get back Radio S-ON in Terminal Emulator, but it didn't work.
3.: Tried some instructions without any result and finally after a reboot procedure the phone didn't wake up anymore. No reaction for the charger, no reaction for any button pushed. Nothing. Took it back to T-Mobile and they check the battery because they thought maybe that caused this and they said it discharged over.
And now I'm waiting for an SMS or call how is my phone now

goodluck with that

Got it back from repair service. They changed its motherboard,so almost I have a brand new phone now I'm so lucky I guess ... huhh ... sweating a lot,but now I'm happy

If you plug it into your computer in that state, does it ask for qload usb drivers? if so, Its a true brick, and there's no way they'll know what you had going on. I had mine replaced in June this year after mine was bricked.

[Q] xperia 6503 wont turn on after update

hi,
I have a big problem.. yesterday I updated zl 6503 thru pcc to the latest software 10.3.1.A.2.6.7, but when it succesfully finished I could not turn it on..
it was never rooted, I just updated it on 4.2.2 maybe 2 months ago and worked perfectly since
I tried every possible combination with buttons (up, down, power, off) but it just wont boot, just black screen and red light is on or blinking
the battery was 100% when I updated
I tried to repair it in pcc in support but nothing shows, I even updated it again thru sus, but it is always the same..
do you have any idea what it is or what can I do?
thanks

I flashed it but still the same, I think there is problem with charging, because when I plug it to power there is just red light, it wont get orange or green even if phone is plugged for hours
maybe this is why it wont boot..

strange thing happened, I already gave up on it and thinking I should take it to sony, but today I just tried to charge it and it did!
when it's full, I'll see if it works normally

it works perfect, seems like the battery was totaly empty, even though it was full when I did the update..
ok now i have another question, 2 months ago I made a backup (.semc-fullbackup) I have it on my comp, I dont know how to restore that file on my phone? anybody know where to copy it?

hi, still the same issue with ZL..
every time I turn the phone off, I can't turn it on normally.. I have to leave it for few hours and then I can start charging it (bright red led), otherwise it's barely red led.. it is like every time I switch the phone off, the battery gets totally drained, even though it is never under 15%, and I think that is the reason it wont turn on
is it possible that it's battery issue or software? let me say that this happened for the first time when I updated to the latest official rom,
now I flashed it to 4.2.1 and it's the same..

HI, +1 I am experiencing the same problem now. Did my own research here, and found there is a way to deal with this. Be patient and be challenged by the problem as this is the objective I believe of this XDA community. Coming from Galaxy S2 I have experienced difficult issues and was able to solve them knowing and understanding the design, and the configuration of the phone. So am not a total newbie to flashing and custom roms. Anyway I consider myself new to XZL and would like to do the critical solving by understanding first the Sony package because I believe not all android phones are made the same Software wise.
My phone is stock, non rooted with still locked BL (JB 4.2.2), it was acquired from a seller in stock and original software condition as I prefer the UI of Sony. Lately the phone strangely began to reboot for no apparent reason, until it decided to just stop totally, doesn't switch on. It will boot up to the Sony Logo then stops dead, and the only way for me to pass thru this state is when I attach the charger.
There could be two reasons I suspect: 1) Battery is drained (although I'm sure I have enough juice) and as mentioned the charger is needed or 2) Firmware problem.
I'll share details later but based on the above I'm more inclined to focus on the second (Firmware) suspect first. My phone still has both FastBoot and Flashmode so still not bricked. Are you with me?

tnx for reply, my phone is also nonrooted, I only downloaded official sony firmware
but I can't even get to the screen where is sony logo, it's dead completely, so I have to wait several hours (maybe the battery needs, I dont know) and then I can charge it.. but when I turn it off, it wont get on again..
I also thought there is firmware problem, but now I have 4.2.1 again and the problem is still here, so maybe it's not firmware?

Try flashing the .423 or .67 stock rom with the latest flashtool for xperia devices (http://www.flashtool.net/download.php).
Maybe pcc screwed something up. On my old Xperia Neo I had several problems after updating with official Sony tools.

Hi Skyline_slo, just an update of what I have done; 1) I read this "http://forum.xda-developers.com/showthread.php?t=1849170" to learn and was able to
make progress on my unit. I drained completely the battery to be able to reset the kernel (took about an hour or so) because from what I have learned on start-up the kernel controls the intial process before the ROM kicks in. So if the kernel has issues, there is a chance that it will reset to default when the power runs down. I was able to successfully reached the red LED state which is the slow charging mode. This state is when the Battery icon with lightning appears on the center of the screen.
Guess what? I was able to boot my unit completely and test the new FW (while attached to the charger) and subsequently made adjustments on the recently flashed firmware (first time by the way using flashtool)
After this, I checked the service condition of the unit using the code *#*#7378423#*#*, and took note of the changes the flashed FW. Then I decided to power down my phone to accelerate the charging time and completely settle the new firmware's adjustments. My hopes are up and high again knowing that the thing is not bricked and just experienced a minor glitch probably the software.
After more than two hours I checked back and switch it on again and to my surprise it doesnt boot, just stock again in the Sony logo. Was a little disappointed but the thing here is, I made progress by ruling out that the ROM has issues, second, that draining the battery will reset the kernel and would lead to completely boot the system. At this point as previously mentioned in my earlier post, my other suspect is the battery so I will work on it today and relay/share whatever I encounter.

hi jun1662,
I'm glad that you're making progress with your unit, because I simply dont have any ideas left what to do with my unit
I flashed it to rom .244 and now I just wont turn off the phone, because I will not be able to turn it on normally again
I'll wait for next update 4.3 and then try if it's any better, but I doubt it
it may be hardware related issue, but why is working perfect when it is turned on?

Update: Definely ruled out software, and made some test related to supply meaning battery, and the result is my battery is defective, it may
provide you with a ample charge but in reality, current is not enough to sustain the requirement display and cores, so it seems the main culprit here is
the battery. Also did my own checking on the other post and inquired on how the problem manifested, and the solution is replace battery.
Going to have my unit serviced for battery replacement, and this is my final actions, if this proves pointless, i'll provide answers tomorrow. Keeping
my fingers crossed.

Phone works on power but not on battery

Hey guys,
My sister owns a Note 2 which is now our of warranty. I've rooted it, flashed a TWRP recovery and gave it some custom ROM love. It has been working perfectly for months.
However, recently, a weird problem has occurred. The device works in charging mode but when the charger is removed, it runs on battery for a few minutes then dies off right away. She has to sit next to a wall plug to use the device.
Now, obviously, my first guess would be to replace the battery. Here's the surprise - the problem is not with the battery. They (third party service centre) took out the battery and insert it into another device, and that device worked perfectly fine. They are going to charge me just to take the device and diagnose it - let alone to fix it. So, I came here to seek some help in case someone knows actually what is the issue.
I have not flashed a new ROM or anything yet because the juice that it holds is pretty risky to play with. But of course, if it is needed, I have no problem doing the troubleshooting.
Any help is greatly appreciated.

if it is the device it can be a missplacement or bad contact of the battery placement (not the battery itself) and that can be quite dangerous. Yet it seems more a software problem. flash a 4.1.2 official firmware ( if your bootloader is older than mj5 or mj5) or your region 4.3/4.4 if it is newer than mj5 (so with KNOX already triggered) then try if it stil drains that much.
Remember to backup data/efs/whatever necessary.

[Q] G3 persistent rebooting issue HELP!

Hey guys im hoping to see if anyone can find a solution to this annoying problem i am having with my phone rebooting on me in the middle of using it. The phone would reboot once in a while and i never thought much of it, but recently(this past week) its been happening way too much. Im using my phone and then it reboots, but it goes into somewhat boot loop. it restarts anywhere from 1 time if i am lucky to around 10 times! once i get it to stop rebooting i use it a bit and it reboots on me again! This was happening in the stock LG OS and i got annoyed and flashed a lollipop rom and its still happening but it only reboots once. However if i start using it it reboots. The phone is becomeing essentially unusable!!! I then started to notice that if i am connected to the charger my phone does not reboot at all! no problem what so ever!
Any ideas of what i should do?
Is this happening to anyone else too?
I was thinking about unrooting it through TWRP and then upgrading it to the latest stock OS but i dont want to unroot it if i dont NEED to.. Any input is greatly appreciated

i know my opinion might sound stupid but did you try a new battery?since you mention that the phone do not reboot if is connected to the charger maybe you found the problem yourself

I haven't, i was thinking about that too but i am not sure if a battery can cause a boot loop? There is another guy thst posted a question similar to this in the LG G3 thread and he also says the phone does not reboot if its charging
I'd also rather not cough up $20 on a battery if i dont need it #brokecollegestudent haha
[EDIT]- Also my battery seems to be lasting me about the same i am about to go back to stock and not download any apps and see what happens

Similar issue
i had a similar issue after installing the new stock lollipop rom via twrp
it was rebooting on me every 10 minutes or so, and obviously that rebooting was killing the battery.
I had to just pull the battery and fix it.
Their may be a less drastic way to fix it. but I fixed mine by going back to stock completely.
I flashed stock via the ToT method and then upgraded to lollipop via the kbz method.
Fixed my phone, it's now working perfectly and I'm very good battery life again
Given that you mentioned twrp and lollipop I'm willing to bet we had a very similar issue
unrooting is a hassle, but at least it's free unlike buying a new battery

same issue - fixed with new battery
I had rve same issue where it rebooted randomly then after a few days just went into a boot loop. However it worked fine while plugged in. The guy in the shop said it was software related but i went ahead and ordered a new battery from amazon and now the phone is working perfectly.

did you order the anker battery? i saw that many people wrote reviews that when they tried using those batteries they got an error saying that the phone didn't support that battery or somewhere along those lines

no, i ordered the original LG BL-53YH from Amazon. You can get them at more than half the original price. Also as an alternative you can email LG directly and explain the problem. I did that and they are going to send me a free replacement battery.

It's a probably software issue. Try this http://forum.xda-developers.com/lg-g3/development/fix-stuck-custom-recovery-trying-ota-t2907508 or revert to stock. I'd say the best bet is reverting to stock via TWRP http://forum.xda-developers.com/tmobile-lg-g3/general/firmware-t-mobile-lg-g3-t2818667

S4 Mini i9195 Boot loop - Recovery problem - Download mode working good

Hi to all, After two years of good working S4 mini is giving up. The last time when the problem is occured, the phone was „forced“ swiched off because of low battery. It was put on charger to charge normally and it did it as usual. But, when it was swiched on again it stayed in the boot loop on the Samsung logo over and over again. When I tried to come into recovery, it shows as normally when it starts to go into recovery with text that it has, as last, succesfully loaded CRC and then it shows for a short text: „There is no command“ and immediately reboot and come out of recovery. I went to „Download mode“ and I flashed in Odin, with no problem, the newest S4 mini official ROM but it didn't fix the problem. Any expiriance or sugestions are welcome... Thanks in advance !

If someone knows... Is it possible that some hardware component inside the phone which is responsible for recovery to work, that is burned out or something like that... ? And if so, could it be replaceable ? Thanks in advance !

Someone with a similar problem and some solution, maybe ?

Did you solve it? I'm having the same problem

Hi Danaidh, Sorry but not at all. I have spoken with some smartphone repairing technician and he told me that it is a hardware problem and that he has to solder some chip and to replace it with a new one. Because it was all happening abroad (Central East Europe), I thought that I will find some software solution here on XDA. Here where I live (West Europe) I didn't try to bring my smartphone to some smartphone repairing centar because they will simply swap a motherboard and they will charge me a full price what means is much better to buy a new smartphone then repairing this one. Even worst, after five months my phone doesn't charge any more and doesn't start at all and all this „smelt“ now on the real hardbrick. I have regulary charged a baterry to keep my S4 mini i9195 in life, but it could be also that it has swiched on it self during transport in my bag and that I didn't notice this and that it has used all battery power by swichining on and off in the infinite loop... But I will check it later if it will be visable on my PC without battery... If you find some other solution send me a message, please... Thanks in advance... Cheers !

I just checked if it will be „seen“ on my PC and it has installed drivers and it's seen as „Qualcomm HS-USB QDLoader 9008“ on COM6 port... So it means that battery died...
But fortunatelly it means there is still hope for this „little bug“(S4 mini)...

Same problem here.. Did they say at least which chip should be replaced?

Same problem here.

Same problem, any resolution?

Gianasy, he didn't say which chip particularly should be replaced, but he mentioned the one who's responsible for recovery ... Or something like that... So, if you have some news on it, it will be nice to share it with us later on... Thanks !

Interesting. I have the very same problem like you (and two friends of mine have the same problem with their s4 mini). I went to a phone repair shop and he told me, that it is "a known problem of the s4 mini" and some part of the motherboard has to be "reparied"/replaced, but he has to send it somewhere and this will take about ten days.

I have ordered a second hand (used - refurbished) mainboard for S4 Mini from China for € 22 - so I'll write here and update you what is going on in about three - four weeks from now... Till then... Cheers !

Where did you buy it? I'm searching for a shop selling mainbords for the i9192 version of the S4 Mini.

I have a phone with the same problem.
Do you think i can use adb's pull to extract something from the phone? So far nothing worked.
In order to use adb I should be able to put the phone in recovery

If you had installed some cyanogenmod, maybe you can use adb while the phone is in recharge mode (=off). I've written a guide, how to extract your data, here.

No cyanogenmod, it's all stock.
I've tried your guide but as soon as I connect the phone (off), it turns on and keep booting (loop).

Interesting, it shouldn't start just by plugging the charge cable in. Someone in another thread mentioned that a defective power button might cause similar symptoms. Have you tried just holding menu and vol-up or -down while it keeps restarting?
When in windows cmd, type
Code:
adb wait-for-device
and plug in the cable then. Does it wait forever or does the command come back?

Same story, unfortunately.
I made a little video. So you can better see what's going on.
After I plug the cable the phone starts and never stop until I remove the battery.
