Basically, I've completely bricked my phone and I'm wondering what to do with it. What does everyone else do with their bricked phones? Sell them on ebay for parts? Smash it against the wall? Brick more phones and build a house out of them?
I've already posted in another thread about the problem - I basically unlocked the bootloader and flashed a custom kernel (DooMKernel) without rebooting the phone in between, and now all I get is a red LED when attempting flashmode or fastboot or when connected to a charger. The phone doesn't respond to resets and taking the battery out made no difference.
Sometimes the phone stops charging and there is no LED at all (I have one of those chargers that emit a high pitched whine when nothing's connected) and then it'll carry on charging a few hours later. I've even tried that "rubber band" trick overnight and the phone doesn't get recognised, all it does is go through cycles of red LED on and red LED off.
Looking forward to hearing some of your suggestions
You could send it to get fixed, or try to fix it on your own and discover some cool new technique that works. What do you have to lose?
On a sidenote, some people here have recovered from these red led problems.

Yeah, I'm currently trying to discover a new unbricking technique - wish me luck!
I've learned a couple of things from this experience:
removing the battery in the xperia s is surprisingly simple
the back cover is held on by a random mix of both torx and "+" shaped screws
the torx screws are T5 sized, not T6 as stated on the xperiablog disassembly guide
the design of the 3.5mm audio jack is quite cool - the actual jack is attached to the phone's back cover and is not soldered to the main board. Instead, a set of copper 'legs' on the jack touch some contact points on the PCB. This means that the stresses from a set of earphones (e.g. accidentally tugging on the cord) will not rip solder joints from the PCB :good: Not sure if other phones or media players have this design but I like it.
my phone is still bricked
I took a voltage reading of the battery and it was down to 3.5v (nominal voltage is 3.7v, max is usually around 4.2v) so maybe this is why it can't enter flashmode or fastboot. I found that when the phone is on a charger and spends a few hours with the red light on followed by a few hours with the red light off, it's actually just doing endless charge/discharge cycles. However, it never reaches anywhere near a decent voltage and this might be why the 'rubber band' trick didn't work.
Right now its charging with the red led off and its at 3.4v. I'm too afraid to leave the phone charging while I'm out the house so I've not been able to continuously charge it for more than 12 hrs at a time. Maybe after a few days it'll eventually get back up to 4.2v?
I got a mad idea when I noticed the battery terminals in a few of my older sony phones were the same, except the polarity is reversed. So I took a fully charged battery from a W995, flipped it round so the polarity was correct and forced it to make contact with the battery terminals....and nothing! Still no fastboot, flashmode or anything. Tried the same thing using a battery from an xperia ray and again, nothing happened.
I'm all out of ideas, I might phone sony and try asking for a quote. I'm so annoyed at this, the phone itself is in immaculate condition. Can't justify buying another smartphone, I've returned to the stone age and I still find myself trying to tap the icons on a non-touchsreen phone

The battery from three W995 probably doesn't have enough power to run the phone. Just keep trying and see what you come up with.

I am noob here,but my kindle fire has the similar things happen like this,Just has little battery the kindle fire can't start,just when the charge all finish ,it can start once,if I didn't others like flash a rom,or just wipe my kindle,after finish I reset,it can't be start,so I start the kindle,let the battery all finish,and then go on charge,when the charge full finish,it can start again,so I have only one time to flash the correct rom,or something after all battery off,and charge full.So I think if you have the same problem like this,if so,just press start button,do nothing to your phone,untill the battery finish(the big point is the battery must run down),and then charge,after full charge go to fastmod to flash what you want,or I think you can just flash stock onto your device.
I thought about buying a replacement battery just to get enough juice to start the phone, but there's no guarantee that it will arrive fully charged and the phone might just drain the new battery anyway without allowing it to enter flashmode!
I have tried charging the battery as much as possible and taking it out the phone for a few hours, then putting it back in while immediately trying flashmode and still no luck.
Last night I phoned sony to ask how much it would cost for a repair. Unfortunately, the nice lady I spoke to didn't understand what a bootloader, kernel or ROM was and just said that sony can't touch the phone if the software's been modified
if you buyed a replaced batterey, you dont you charge full it and then put into your phone and flash the stock? Try this,and dont forget installing the driver for your phone into your pc

I'm not sure a replacement battery will let the phone enter flashmode, I mentioned earlier that I tried various spare sony ericsson batteries (same voltage rating, but fully charged) and the phone still did nothing
I think I'm either going to sell the phone on ebay as faulty and perhaps get a new phone after that....or I could buy a faulty xperia s from ebay (with superficial faults like touchscreen damage) and do a motherboard swap.
Edit: I've managed to fully charge the battery using a borrowed phone, confirmed it was over 4v with a voltmeter, but still no flashmode
So I woke up this morning to find my Tab drained. I plugged it in for half an hour, then when I picked it up I noticed there was no charging indicator (the green liquid battery thing). So I thought maybe I didn't plug it in right. I reattached everything, tested the charger on another device, then plugged it back into the tab for about 2 hours...still no juice. I tried powering on and doing the reset thing. still nothing. I brought it to a Samsung service center and they said I have a faulty motherboard. Now I'm wondering how the hell that happened when I've been using this device for about 6 months (only 6 months) without any issues, no overheating or strange reboots or anything, and now just like that I have a motherboard issue? The kicker here is that they're charging 75% of the tablet price to fix it! What gives?! I purchased it from a non-samsung mall store so they said I can't claim warranty. I popped the back off and did the battery pull thing and tried to charge - still nothing. Did I buy a device that decided it was a lemon after 6 months light-moderate use?
Anyone else have this happen? It's never been dropped or anything and I was on stock firmware with nothing but root.
In the UK, If your tablet goes faulty in 12months your guarantee is with the place you bought it from, not Samsung.
John.
It's ALIVE! I thought I'd get a 2nd opinion on my Tab since the guys at the Samsung service center popped it open anyway. Went to a generic phone repair store, all they did was hook it up to this box thing, and it came back to life! The guy said something got corrupted and just re flashed everything to stock rooted. He charged me less than $20 and I have a working Tab again. Obviously the very first thing I did with my resurrected device was to call Samsung's hotline and report how this one service center was trying to scam me into buying a motherboard that cost nearly as much as what I paid for the thing brand new.
Some li-poly battery have an protection circuit built in, if the voltage falls below a certain level say 2.5volts per cell, it disables the battery, if you connect an meter to the battery you will get 0volts , you need an li-ion charger that passes an higher voltage that resets the battery and allows it to work again, I wonder if this is what happened.

John.
Did they connect via USB or to the motherboard?
@tinderbox could be...must have over-drained itself for some reason.
@ashyx I couldn't really see what he was doing since his work table was obstructed by a bunch of stuff and he had his back towards me, I just saw him grab this small black box, then minutes later he showed me that the tab was already powering on though couldn't get past samsung logo, then he went ahead and flashed to stock.
Reason I ask is I wonder if he used a jtag box to ressurect it by reflashing the bootloader.
If he did there must be jtag points on the board as it can't usually be done via USB.
Pity you didn't ask what he actually did as I'm intrigued now.
Did the box look like this: riff box

Exactly the same or just similar?
yeah i think so... it had similar ports, though not sure about the outer shell of it... i think it was smooth all around with no ridges or anything, just a little black rectangular box.
Sorry to revive an old topic, but i thought i'd do an update instead of start a new one. Tab S died again and I'm now convinced it's over-discharge, as I left it at about 20% and forgot to plug it in before going to bed. Woke up with the tab drained, not responding to any button combinations, not charging with any of my chargers that tested ok with other devices.
Instead of bringing it back to the technician, I thought I'd try mcguyvering the damn thing. I opened up the back, pried the battery terminals up off the board, lifted the battery out, and with a spliced USB cord hooked up to a powerbank, I gave the battery terminals a direct zap, inserting the exposed USB wires into the battery terminals. This took some trial and error as, I didn't know which wire was supposed to go where, but finally I saw the powerbank leds blink, indicating it was discharging into something. I held the wires in place for about 5-10 minutes, noticing some heat on the battery by then. I reinstalled the battery back into the tablet, closed everything up and tried charging again and...hey presto! the tab started charging. :victory: Let it charge for 2 hours and powered on like nothing happened.
disclaimer:
I don't recommend you defibrillate your device's battery unless you know exactly what you're doing and are fully aware of the risks. (I didn't know what I was doing at the time but I was so frustrated at that point I didn't mind if the battery blew up in my face.)
Mine just dead last night while CHARGING (turned off at 13%).....
And refused to turn on till now (still charging and both warm (charger + tab)...
I even plugged an ampere meter to really know if its drawing any or not (it is, at 5.2V 1.7A for 15mins)...
And still no luck
Samsung's device become more ****ty each generations..... Esp the battery...
This one is the replacement batt they gave me after 2mos of usage for infamous Tab S battery issue...
I saw a video on youtube, a guy had a dead 10.5" T1 he took the back off and connected an 1amp microusb charger pcb to connections directly to the battery under a piece a tape, I bought a couple of the microusb charger pcb`s from ebay for 0.42p each in case mine goes dead.
EDIT: I found the video.

Samsung tablets only have issue with battery connectors. The white connector with 6 wires has loose connection, the black connector soldered to mainboard has cracked solder joints. New battery won't solve problem if you don't fix these two flaws. Resolder the battery connector will fix most of problems: not charging, reboot, flickering, auto shutdown.
I posted more details in the threat: flickering screen.
so the problem is Samdung's QC....
anyway no more somedung, I switched to Xiaomi Mi Mix, still preordering from China.....
You have to watch these chinies owened tablet and phone manufactues, they have been found to come with built in spyware, sending copys of all your texts ect back to china, it`s been in the news that last few day`s
Lenovo notebooks had a spyware app and Lenovo had to issue insturctions on hot to remove it once it was found.

That's OK, I can scan and remove all those spyware.
Still its better to have it properly supported with actual updates (older phone still got all UI + android update, hello MIUI 8).
Rather than using phone without proper software support....
Tab S - buggy and prolly the last MM update
Note 3 - useless LL update, very unstable, consider alpha
Note 8.0 - buggy last KK update, switched to CM13 and happy with it
This is my older son's N7. A week ago he was playing some dumb game and it froze on him. He, intelligently, immediately restarted the N7 and continued to try to play. This happened about 7 times. The last time he said the screen glitched and it turned off. He then plugged it in and it got very hot according to him, for how long I don't know.
So now I took it apart. The battery was 3.4v-ish and not charging, so I hooked the usb up to it directly and charged up to 4.09v and tried. Still won't turn on (and yes I tried all combination of buttons and lengths). Plugged in the usb, tried again, no luck. But I did notice the qualcomm chip getting very hot very fast.
So what is the next step here? I cannot find a lot of information on this as 99.9% of the time someone just ran their battery completely dead and jumpstarted it back to life. I don't have access to proper reflow equipment so thats off but I'm not against a ghetto heatgun reflow. This thing is long out of warranty so I'm willing to try some invasive tricks on it.
Connect it to a PC and check if a new USB device, id 9008, has been registered. If so, the eMMC chip is gone - more info in the link in my signature. Then in the linked thread please post the maker of your eMMC chip for our statistics.
A bit more info...
I accidentally left the battery plugged in and it drained down to 0.2v , just by sitting there. Hoping it was a battery issue and to kill 2 birds with one stone I ordered a new battery which came in today, plopped it in and... nothing. I tested the battery and it had a charge but it just did the same thing again.
Nothing turns on. The qualcomm chip (or that area in general) heats up, I'm assuming its just sitting there eating the battery. Plugging it in doesn't help (tried 3 chargers, various amps) and it doesn't charge the battery. Last I checked after "charging" a few hours the battery was down to 3.3v , now it's just sitting there unplugged from the motherboard to prevent further damage.
And to answer your question "Connect it to a PC and check if a new USB device, id 9008...", watching "dmesg -w" in linux, not even a blip.
I don't want to keep buying random parts that don't fix the issue and my google-fu failed me in finding any real hardware level testing. So how do I find out what the problem is here?

What do you mean "so I hooked the usb up to it directly and charged up to 4.09v and tried" ? I once soldered a micro usb port directly to the motherboard for charging and in doing so inadvertently created a short between the id wire and a tiny component. Result: CPU heating up quickly and no sign of life. Eliminated it and it was back to normal. If you have done any soldering, check carefully for possible shorts. Some require a magnifying glass (mine was 10X) to be visible. I've not heard many cases of battery suddenly gone dead with this model.

usb wires connected directly to the battery itself, at no point was anything plugged into the motherboard. Also I have done no soldering to the mb so there is nothing to look for in that regards unfortunately.

Please disconnect everything from the motherboard except for the battery. If the chip still gets hot and the battery drains down then the mobo is faulty and you can replace it for around $25 http://www.ebay.com/itm/121637666631
I see no hope of component-level mobo repair because N7-13 has no available circuit diagram.
Finally got around to doing this. Everything disconnected, connected the battery and within about 10 seconds the qualcomm chip is too hot to touch. These chips run hot (or so I've read) so what are the odds it desoldered/fried itself?
A few days ago the S4 mini got hot and froze and I turned it off and turned it on again but it got stuck at the Samsung logo (for the past month it used to drain the battery quicker than normal).
I then turned it off and on again and it got stuck on the same Samsung logo screen.
When I tried to turn it on again it didn't work and hasn't worked since.
Problems:
Doesn't turn on or vibrate
It doesn't charge the battery.
Doesn't boot up in recovery mode
What I have tried so far:
I have drained the electric charge in the circuit board by holding the power button without the battery inserted
I have used another charged battery and the S4 mini doesn't turn on nor does it charge that battery. HOWEVER it completely drains a charged battery! This is really odd....
I have opened the phone and nothing seems burnt nor is the power button broken
When I connect the phone to a computer the computer pings and acknowledges a device is connected but then immediately makes the sound when a device disconnects...
I just want to get some data off the phone which was saved to the phone memory.
Any help will be appreciated.
Any help please?

No I get no notification in device manager.
The other day I purchased a DC / AC power unit and connected the cables to the positive and negative terminals (where the battery would sit) in the hope the phone will fire up. I turned up the voltage to 10 after 5 didn't work and I smelt burning. I thought some more voltage would help....
After that the computer doesn't make that sound anymore when you connect / disconnect a USB device.
I connected the terminals to a working a phone and the phone turned on without the battery at 5v.

Samsung have created these monsters to die after four years so people go out and buy more phones it's a joke!

well flashing a different rom did help, and using a slightly different battery (not original-compatible) on the phone also helped,
but otherwise not much helped to fix this phone.
Hey everyone,
I have an HTC One M8 that I threw in a box after I upgraded to a new phone. However, recently I've tried to pull it out to try to experiment with it, since it has an IR Blaster built in and I wanted to try making it into a spare remote.
The phone is refusing to boot at all. I've searched the issue and I've tried all the suggestions I've found: Letting it charge for a bit then trying to reset the battery, letting it charge overnight to try again, ect. Holding anything doesn't give me any response from the phone at all. While it's plugged in, the phone has an amber LED that lights up for a few seconds and turns off, lights up for a few more seconds, then turns off for a little while more before starting the cycle again.
If I try to plug the phone into my computer, it recognizes it as a 'Qualcomm hs-usb qdloader 9008', which from more searching tells me that the phone could be bricked... but I've never tried to flash anything on this phone. It should be running stock Android. I don't know which version of android since it's been in a box for so long, but I'm about 95% sure it's stock.
Is the phone just entirely dead from sitting in a box for a few months, or is there a way to salvage it?
There are 2 options: Your phone is hard bricked and maybe it can be repaired, maybe not.
Or your battery is dead and need to be replaced.
How does a phone brick itself by being in a box for a few months?
Are those the only two options? Either it's dead or dead?

Make sure you charge with wall charger (not connected to a computer) and try another charger and cable. Charge overnight, and then try holding power+vol up for a minute or more. The last part is key in the current situation. I've seen a number of folks (myself included) that freaked out that the phone wouldn't come on, when we just needed to hold the buttons longer.

The Qualcomm "download mode" message (when plugging the phone to computer) will come up if the phone is bricked, but that is not the only situation that will give the Qualcomm message. This message will come up, whenever the phone is powered off, even a perfectly working M8. No USB interfaces can connect when the phone is powered off, that is all the message can conclusively tell you. That can be from a brick situation, or low battery, or simply if the phone is turned off.

How does a phone brick itself by being in a box for a few months?

The battery won't take a charge, if the voltage is allowed to drop too low. Usually, there are safeguards to prevent that from happening. But it does happen in some circumstances. Leaving it powered off for a long time can be one of those circumstances.
If charging overnight, and holding power+vol up doesn't show any improvement, you can try taking it to a repair shop. Some shops have special battery chargers that have a "boost" function, that can get the voltage high enough the battery "bring it back to life". But they may need to take the phone apart to do this. At that point, you may as well get a new battery.
