I've had my Sensation for a week or so now... rebooted it earlier on, and now it's totally dead. Won't power up, won't charge, or anything.
Any recommendations of anything to try that I might not have tried? I've got a good background in this kind of technology, so I've tried the usual stuff - battery removal, leaving plugged in, holding buttons for longer etc...
Is there a trick that anyone's found?
If not, should I go back to '3' to replace it... or should I go to HTC and see if they'll replace with a nice S-OFF unit??
Thoughts please?
volume down and power button together and see if you can get recovery screen up and do a factory reset
Hi Gavin
Sadly it needs something more than that - that was the first thing I tried, thinking it might be software related.
Even tried leaving the battery out overnight before trying again, that didn't work.
What I have found, now, is that if I plug in the charger FIRST, and THEN connect the battery, I get an orange LED. I thought this might mean it is charging, but no, because when I unplug the charger again, the orange LED stays lit, and remains so until the battery is removed again.
I don't recommend trying this yourself, because it does say somewhere in the literature, NOT to apply power, without the battery being in place. I just figured, it's already dead, so it might do something different!
What I'd like to know / find out, is if there's a real "hardware" reset switch/button... my Toshiba TG01 had some hidden PCB pads which would allow different booting modes, etc... somethign like that I think it needs. I'm going to have to get a new one ANYWAY, but it'd be good to know what happened to this one, first!!
Sounds like a hardware issue to me (maybe motherboard failed, that was an issue with all previous HTC devices)
Put it on charge without the battery. Now with a paperclip hit the +- pins for a second. After that unplug it and put battery in and normally charge it. Friend of mine did this with his Sonyericsson and it worked. Otherwise send it back to htc.

Ok, I've spoken to HTC, and as it's within the first 28 days, the onus is on 3UK (Hutchinson3G) to replace the handset.
Spent over an hour in store with them this morning, trying various things, and they decided that they would replace the handset. Except they then realised that they won't replace handsets which were from 3 'direct'.
So, I figured, can't hurt to try the 'shorting' method - I would again, out of a background in electronics, say DO NOT TRY THIS METHOD, UNLESS IT'S A LAST RESORT! IT COULD SERIOUSLY DAMAGE THINGS.
Now, instead of a constant orange light, I've got a flashing orange light.
Still no actual operational power though.
Thinking about it
This reminds me of a laptop I used to have - it had a "Quick Boot" feature which relied on stuff in the boot-area of the hard drive. Back then, I had a 'less-than-legitimate' copy of Windows 7, which used a boot-modifier to work as "genuine".
That laptop would, on occasion, refuse to power up for hours, and sometimes days at a time - and I traced that down to it being an issue relating to the loader software in the boot area of the HDD.
I wonder if this is a similar issue on the Sensation - an exception in the "quick boot" that makes it think there's still quick-boot data, even though there isn't, because the battery's been out. It's all hypothetical, but interesting to know how these things tick.
And who knows, maybe 3UK will send me an S-OFF unit in replacement.
i honestly dont know why you would try shorting your phone thats still under warranty. Are you trying not only to fix your phone, but also void your still current warranty?
take it back. get it replaced, and stop trying mcgyver tricks. Its just not needed.
Leigh,
Thanks for your concern for my handset. Personally I'd say having a brand-new, week-old handset to fail completely and spectacularly is 'not needed', either (!) But, really, any of the above actions, which were given to me in good faith, were up to me to use, or not use. I made a calculated decision based on i) the current level of operability of the handset ii) the likelihood of any action taken voiding the warranty iii) the likelihood of my receiving a new handset under said warranty. I hoped I made it clear enough that anyone who would even THINK to consider performing the above procedure would also make such a calculated decision.
I don't know who McGyver is, but you'll notice that I did put a warning in my post stating that others shouldn't try it... chances are it would cause damage to the phone's power management, at the very least, it's cause wear on the voltage regulation side.
That said, there are times when simply shorting devices *can* work as said devices can hold small amounts of charge which can be dissipated with a short, a reverse polarity or otherwise. The cavaets being - a) it's already totally and completely dead, short of it going in flames, it cannot be made worse; b) the shorting (or other action) is momentary - the smallest fraction of a second.
Yes, it's under warranty. Yes, they're going to replace it. If we wanted to go into the whole matter of ethics, *if* I were the manufacturer, and I had proof that someone had done the above steps to their handset, NO, I would not honour the warranty. But I'm not, they don't, the handset already more-than-likely has a mainboard failure, so I was prepared to take the risk.
Eventually, the Service Manual for the device will be released, and this will help with matters of apparent hardware failure. In the meantime, it's a learning curve for everyone, and if I could help that curve at all with my dead handset, in the knowledge that a new one is coming, that's what I hoped to do.
Again, for all clarity, safety, etc. I am not advocating, or recommending the actions detailed above, or ANY other action other than in accordance with the user manual which was provided to you with your device. Do ANY of the above STRICTLY at your own risk, and on your head be it.
If anyone else has any ideas - "McGyver" or otherwise (who is he?!) - that won't obviously cause warranty-replacement issues, I would be happy to try them in the hope of furthering the knowledge of this new device. I'm grateful for any help, and for any chance to increase the small amount of knowledge we already have on this device.
McGyver is a character in an old American TV show from the 80's.He always got into impossible situations and always had some tricks up his sleeve like making a laser out of a package of gum,a paperclip,and a match.

maybe it's the battery
I hat the same problem on my TG01, at the end it came out the Li-ion was all draind and my TG01 would not Charge it anymore.
not eaven in an external Charger
New battery was the only solution.
Maybe it's the same problem you have.
Hi GhostRider
I remember the days of the TG01 - turned out a decent handset, in the end.
I'd hope it's not a faulty battery on a week-old handset - although I don't have another battery to test it with, so I suppose it's possible that it was manufactured as faulty.
My new handset replacement arrives on Tuesday though... but I'll keep checking here to see if anyone wants me to do anything with this one in the mean time.
Had my first Sensation for a week and then it beeped and died just like yours. All I did was swap the battery and plug in the charger. Still nothing. Called TMO and got a replacement.
I think even if you managed to do CPR and get it back up the fact it died in the first place indicates a serious problem. Personally I'd rather have one that's reliable.
I would be excited if my sensation bricked, I've been trying to brick it for a few days. sadly no luck. If it is bricked tmobile atleast will replace it with another, that's atleast another chance at getting s-off.
Mine did what yours did the other day. I thought it was ****ed. I took battery out for 5 and after that put it in and charged for ten minutes. Sadly, it worked fine after that.

s-off i hope?
My replacement is due around 1330h (UK time) today.
I'll let you know the status of the new phone when it comes.
I'd bet a beer it's *STILL* S-ON though...
Here's hoping!!
Ok, my new Sensation has arrived.

Oh well. At least there's perma-temp-root for now
I've followed this course to its natural end, however, I appear not to be the only one with the 'dying sensation' problem... so might be good to keep this thread alive?

Soo I have a big problem,
My sidekick 4g suddenly shut off and directly went into Download Bootloader. It would only stay in that window for about 3 seconds then restart. So I tried doing Odin but it would never stay in download mode long enough. After a while, the phone stopped turning on and now it does not even charge. I believe I have hard bricked the phone. When I leave it on the charger. I see no indication that it is charging but the battery gets warm. Is there any hope for me to fix this phone?
Please let me know ASAP. Thanks!

Does the device even show up as a USB vendor/product id? See that with `lsusb` on Linux or the Device Manager on Windows.
It might be worth trying ayoteddy's FOOL PROOF WAY TO GET INTO DOWNLOAD MODE here:
http://forum.xda-developers.com/showthread.php?t=1186954
Perhaps if you trigger the phone to enter download mode that way, it won't just continually reboot...
Beyond that, I think you'll be looking at hardware-level fixes. If the phone isn't literally fried, it can almost certainly be repaired with JTAG. But that would involve a JTAG interface which I am guessing you don't already have.
You might be able to find someone who will JTAG for you for free, or for a fee. A local phone repair shop might have this capability.
If you're damn good with a soldering iron, or have a friend who is, there's also AdamOutler's "UnbrickableMod":
http://forum.xda-developers.com/showthread.php?t=1347984
That mod is not for the feint of heart, you need to take the phone almost entirely apart and do soldering work within the area of a grain of rice... but it is possible.
But all the options assume that the only problem with the device is a bad flash -- damaged boot loader, bad kernel/recovery, etc. The way you describe your phone's demise, a hardware failure certainly seems like a possibility.
Good luck, I hope your device is not dead.
FWIW, SK4G goes for ~$100-200 on eBay these days depending on condition. Locally you could probably find lower prices.
Wow thanks for all the info but i tried ayoteddy. Since the phone doesnt even power on , i cant do what teddy says. And no, after a few failed odins, the comp doesn't even see the phone. But that's also because the phone doesn't turn on. I even put a charged bat. Still no go

It really sounds like a hardware failure.
If you are committed to trying everything to rescue your particular device, you could double down and try a new battery. You risk wasting whatever money you spend on it, of course.
If I recall correctly, the SK4G can't operate properly without some battery current, even when plugged into USB. And the other symptoms seem to leave the door open on battery problems -- sudden power down, brief signs of life which eventually cease, hot battery. The sudden failure of a lithium battery would hardly be unusual.
I have seen an issue very similar to this before. It turned out to be a loose connection inside the phone. Might want to disassemble and reassemble carefully to ensure that the connections are secure. Youtube has dis-assembly videos to guide you. You don't have to completely disassemble the phone, just til you reach the main board and secure the connections to it. If you don't feel like you can hand the task of dis-assembly you could always search for a local phone repair business, or even computer repair shop (they often do some phone repairs). Hope this helps
Hey there, I am trying to fix a SK4G with the exact same problems... download mode will show up, but then the screen will go blank again. I'm gonna look into what blk2dr suggested... did you ever fix yours, OP?
root? so Warranty it, not saying its the most "ethical way"
out of curiosity what was the last, well as samsung would put it, hac...ERRRR unsupported warranty voiding modification known to us as upgrade/flash eg. via cwm odin rom app add on modem kernel etc. that was done to the ol SK? or is it just straight up faulty craftsmanship from samsung...nooooo on a SK4g??? is that possible? lol moving a rom around from folder to root of sd once (zip prev passed md5 check) my 2nd or was it 3rd t839 had a lil hiccup that i didnt realize at the time made my custom Roms zip like 47kb smaller then it previously was and should of been, when flashing is 2nd nature and ur just moving it within the same sd card its already checked out on the md5 sum and ur dealing with a 200+/-mb file, whos gonna notice that minor change? to make a really long story just kinda long, into voodoo cwm flash, let it marinate... phone ran great for 4 days, then i decided i was going to clear cache davlik fix permish and reboot...yea went into cwm wiped wiped and half way thru fix permish phone crashed rebooted back into recov, when i tried to reboot sys it had your same exact issue. DL mode for just a second...then all black yet slightly backlit screen. could never get it to stay long enuff to odin back to stock, fullproof DL mode was a no go and of course the battery died, wouldnt recharge. i played dumb went to tmo store dude tesed phone with new batt my batt in other sk etc etc...anyways he charged my battery up enuff it flared back into dl mode for a few sec...my fix? hours and days headin into weeks of jackin with this thing i went with my cure all root REUPwarranty fix...flash a bad freakin bootloader thru odin and kill it once ad for all, DL mode only needs to be on about 4 sec, not long enough to go back to stock rom but long enuff to kill that B. prefered bootloader is i9000 haha works like a champ everytime to every rooted phone that had issues i needed a warranty exchange on(only been 4) seeing how i get a new phone every 3months on avg and always pay full price the ratio is tiny. yeah i know the trickle down effect raising costs from manufacture in long run yadayada. all is true, but i figure ive been kicked in the groin so many times by samsung,lg,moto,htc etc they can eat 1 every now and then. as a tmo employee in 07/08 i paid 500 upfront for the mda that got back ordered for 6 months had 2 bad dead spots in the touch screen within a month and screen went completely white in 3mnths. some employee/warranty fine print screwed me out of a new phone. and dont even get me started on the sidekick. 399 bucks for a phone that basically got abandoned 3 months later cuz it was junk compared to what it should be and breaks in high quanities. theyll still tax u 20 bucks and make u keep ur old battery and cover charger etc so im not losin any sleep, for real kill it for good, run it to the store get ur new err rebuilt refurb SK4g in 2 days then save up for a t989 s2 dl gmote/spashtop and poweramp on ur SK4g and let her roll as a wireless keyboard/mousepad for ur pc and let the voodoo and Pamp rock as a killer mp3 player. thats all the T-urd-839 is really good for anyways, oh yea and a mediocre bt controller for playin games on my S2's lol do the warranty, its samsung/TMOs fault for lettin this junk product get released, abandoning it and overcharging so many of us. Just do it, do it lol
pull battery, connect usb, hold power, volume up, volume down, camera, and tackpad and insert battery. It should FORCE the phone into download mode.
try it lol~
tl;dr: My chronology of the infamous LG V10 boot loop death which got repaired under LG's unannounced extended 15 months warranty. Important lesson learned is make sure to back up all the phone's valuable data (even though I technically didn't lose anything critical).
01/03/2017: I finally experienced the infamous boot loop of death with my AT&T LG V10 yesterday (01/02/2017). The boot loop I encounter isn't due to flashing gone bad or wrong, but due to regular use. My phone wasn't excessively overheating at the time, but I do know that the metallic ring around the power/finger print sensor was warm due to surfing the internet at the time on Chrome. I do have a tempered glass on the phone and a slim translucent plastic cover to protect my phone. What happened was that my phone suddenly just powered off the display screen. I thought the phone just experienced a force close and forced reboot, not that I ever experienced one with the V10, but other Android phones before (i.e., very old ass Android phones). But I waited for the phone to boot up, but it never did. I tried to reboot the phone and then that's when it got to the home screen and locked up. Ever since then, reboots failed to get pass the AT&T logo, but could pass the LG logo.
I've already tried the refrigerator/freezer trick to cool down the phone, but it appears that I'm passed that stage where the phone would not boot pass the LG logo or AT&T logo. The more I tried to get the phone to boot up, the more it will just stall or reset at the LG logo, or refuse to boot up (i.e., speed up its death). Even the charging screen once showed, no longer reaches the charging stage where it shows the percentage of the battery's power remaining through the wall charger or being plugged into a computer laptop. Pulling the battery and letting the phone sit idle (to cool down the internal circuits?) for a while will allow it to come back to life with the boot loop problem or the ability to charge the battery via a computer's USB port. I tried charging with the wall adapter, but that forces the phone to boot up, and render the phone useless thereafter, so I elected to charge the phone via computer.
My AT&T LG V10 (H900 variant) is on Android 6.0 (H90021w00). It's not rooted anymore due to upgrading to Android 6.0 (I updated back in November 2016 here) without issue and wasn't abused (e.g., phone dropped, water damage) for it to cause the boot loop of death. The hardware version (H/W) is 1.0 with the SKU 6084A. Battery manufacturing date appears to be 2015.11.07 (D). The OEM package boxing has DHHS Code MC1, manufactured date of 12/2015 and made in Korea.
I wanted to try and save some data off of my phone, but the phone couldn't stay on life support long enough. Of course, fastboot won't allow me to save data (it's design is to write data only). I did manage to put the phone into download mode (i.e., phone powered off, hold down volume button and plug in USB cable from computer) one time and try to flash an upgrade of Android 6.0 firmware H90021w00 with LG Up, but it failed somewhere after 10%.
Good thing I have Google Photos backing up all my photos and videos, and nothing critical resides on my phone other than auto logins. I'll just have to change all my passwords soon enough if my phone has to be taken away for warranty. I wanted to at least save data and do a data wipe to make sure that nothing falls into the wrong hands. But I now can't do any of the two. I called the nearest AT&T corporate store, but was directed to one that has a warranty center. I will be on my way to an AT&T corporate store later tonight that has a warranty center. Just doing so to avoid traffic. I know my phone has the usual 1 year warranty, and speaking to the AT&T corporate store with the warranty center, I was told that I have at least 80 something days left of warranty. So good thing I'm not screwed and can at least get a replacement phone.
Currently the phone is sitting on my desk charging at a slow ass rate and up from fluctuating anywhere between 12% and 21% to a now whopping 30% power capacity. I want to at least demonstrate the boot looping to AT&T personnel and it's not due to physical damage or water damage. I'll report back what's happening with my situation so that way, anybody else who experienced this situation will have something to go by.
Update 01/04/2017: I read through the freezer trick thoroughly this time and the entire thread. I decided to try it again, but this time, I left the phone in the freezer for a short time (half an hour or so) without the battery. After time elapsed in the freezer to cool down the phone, I plugged in the USB to the phone while having my laptop near the refrigerator with LG Bridge loaded and ready to back up, and then put in the battery. Lo and behold, the phone did manage to boot up all the way to the lock screen, due to various sound cues from the phone (AT&T logo) and USB connectivity (from Windows 7). However, when I tried to unlock the phone, that's when it froze and rebooted. After that, it hit the boot loop and won't get as far as the initial try. So I'll keep trying to revive my phone long enough to get some data off of it and wipe it clean. I still have time with warranty, so I'm in no hurry. Besides, I attempted warranty processing last night and missed the opening as the warranty department closed early.
Update 01/11/2017: I managed to get my LG V10 phone to boot up further than the freezer trick by utilizing the hair dryer trick here. Basically, what the video shows is that one must take a hair dryer, blow dry on the highest heat setting to the bottom of the backside phone up to the point where the phone gets hot, without the battery for over a minute. After that, put in the battery, boot up the phone and blow dry the bottom of the phone and heat it up even further while it's booting. I had to repeat the hair dryer heating process many times in order to stabilize my phone because it would reboot within minutes after I try to initially back up with LG Bridge's LG Backup tool. I did manage to overheat the bottom part of the phone so much that Android denied charging the battery via USB connected to the computer. Further exacerbating the problem was that the battery was so hot, LG Bridge denied backup because it thought the battery charge status was under 30% when in fact, my LG V10 showed at 49%. I did get the most important file that I was after on my phone after many tries (kept rebooting on me), but I'll persist to back up the entire phone in case I needed something else before turning this phone over to AT&T warranty service.
Update 1/19/2017: As much as I tried to back up my LG V10 and wipe afterwards, my attempts were futile. The phone couldn't stabilize enough after reaching the home screen, and would reboot shortly thereafter. At least I got what I've wanted. When I kept trying to revive it with the hair dryer trick, it just wouldn't go pass the boot screen most of the time (i.e., LG logo or AT&T logo). It even got to the point where it would turn on slowly (i.e., there's a delay booting up when power was pressed on). So at this point, it appears that the boot loop of death is sinking in further into my LG V10. I also tried the freezer trick again and then going back to the hair dryer trick when the freezer trick stopped working, although not back to back, otherwise that would provide temperature shock to the components. The freezer trick did manage to get further, but it only happened twice where it got to the home screen and then rebooted. Note to those wondering if condensation would trip or activate the moisture sensors on the phone and the battery, it does not when you take careful steps of taking the phone out of the freezer and putting it into the refrigerator and then take it out, letting maybe 10 minutes pass by for each step of temperature transition so that the phone's temperature can get to room temperature without condensation buildup.
Anyways, I decided that I've spent way too much of my time trying to revive my phone to back up data that most likely I wouldn't need. I went the route of sending my phone to LG for repair instead of going to AT&T store and receiving a refurbished LG V10. I'd rather have my phone repaired by LG and receive my phone back with the repaired hardware than to receive someone else's LG V10. I based my decision on this thread here over at Android Central where someone sent in their phone for repair, got theirs back with a clean start (i.e., don't expect LG to either back up your data or reuse your memory storage as no personal data was saved). It is good to note that LG has extended LG V10 warranty of 1 year (12 months) to 15 months. I'm pretty sure LG granted a 3 month warranty extension on LG V10s due to the boot loop issue. I didn't realize I got the extension until thinking back, when I called AT&T warranty center, they told me I had about 86 days of warranty left, which is about 3 months extended from my 1 year of warranty when it ended. The phone was bubble wrapped (removed back cover, battery, SIM, microSD) and shipped off in a small box that I re-used from another item that was shipped to me. Shipping carrier is by FedEx Ground that was paid for by LG, being shipped to LG's repair center in Texas.
Update 01/24/2017: The phone has arrived at the Texas facility yesterday (Monday) according to FedEx, but the status of my repair hasn't been updated anymore than giving me estimated delivery date of 9 days. What's odd is that LG didn't update the received date at repair facility field and have deleted my FedEx tracking number.
Update 01/25/2017: LG updated the repair status last night which pretty much acknowledged item received, diagnosed, repaired, and prepared for shipment back to customer. The repair was "Swap Board (Main/RF) : Others". I should have the phone back on 01/28/2017 and will update then accordingly. It appears that LG probably replaced the entire mother board which would include the 64 GB of memory holding user data, among others. Considering that others have reported of receiving a freshly formatted phone, I would expect the same once the phone reaches back to me. I would highly doubt LG went the extra length to migrate data off of the failing motherboard onto the new one. It would be nice if they did.
Update 01/28/2017: I have received my phone today via FedEx Ground shipping, and they delivered on a Saturday. The status of my phone was factory reset. I can tell it was factory reset because I still have the unlimited tethering (hotspot) enabled from the previous rooting (Lollipop) and then went to Marshmallow and losing the root, but still have unlimited tethering. Also, Android OS is updated to H90021x (from the previous H90021w00), build number MRA58K, with Android security patch level 2016-11-01. You will need to set up the phone just like you did the first time. They also removed my tempered glass and left a narrow sticky film that doesn't cover the entire front screen glass that can be peeled off. Good thing I have an extra tempered glass for the V10. The phone came back with the same serial # and ESN/IMEI that I've sent to LG. If you're like me trying to migrate data from one LG phone to another, it's best to use the LG Backup in Backup & Reset under Settings that's found native in the phone. LG PC Suite and LG Bridge won't work with Verizon's LG G4 (VS986) on Windows 7 for me, no matter what I did (installed many LG G4 drivers, including Verizon's). Some backup apps, such as LG Backup (Sender) and Super Backup & Restore do not back up everything, neither does the native backup LG Backup in the Android Settings menu.
Update 02/03/2017: What appears to be a puzzling action on my repaired LG V10 is that I'm going to take no chance and back up my phone in case I end up losing data again. What happened earlier was that I was surfing the Internet with Chrome, reading up on a news article, when I was prompted to Miracast and enter a PIN. WTF? I ignored it a few times and then it got to the point where my phone was unresponsive with the Miracast prompts, but I was able to force my phone to reboot. Upon reboot, I noticed that the phone loading up was sluggish and not typically responsive. I decided to shutdown my phone to prevent further irreversible problem in the future (hint: boot loop). I waited for my phone to cool down for perhaps a few minutes before I powered on the phone again. This time, when the phone booted up, it was responsive as it normally has. Before all this happened, I didn't use my phone excessively nor extensive in a short period of time. I really have doubts that LG really applied a fix to their faulty connection problem and just used a replacement just to pass by.
Update 02/04/2017: I received an e-mail from LG requesting my feedback with respect to the repair. I gladly answered the survey, gave them good credit with respect to the repair itself, but when it comes to the quality of the LG product, they took a hit and I expressed my concern with respect to the boot loop.
These bootloops have been happening quite a lot lately. Makes me worried.

I would suggest that anybody with a functioning LG V10 to do their due diligence and back up their data on the phone in case there's a catastrophic event such as the boot loop I've experienced. At least I have most of my data backed up. Just some that I disabled but now realize it's worth having.
It happened to me too on Nov 2016. I have been told to return the phone to AT&T and get a replacement phone under warranty. I did receive a replacement V10. Now AT&T pissed me off on changing the phone contact expiry date to next year. I am on AT&T Next 12 plan. I am supposed to get a new phone on January 2017, but now I have to wait till 2018. Next time, I am buying phone myself.

A replacement phone under warranty should not extend your contract. Did you contest the contract extension? Under the warranty exchange, there's no mention of contract extension required: https://www.att.com/esupport/article.html#!/wireless/KM1044996
Its kind of best to buy the phone out right.
On AT&T Next. What ever payment plan you choose, you dont get to keep the phone until it is completely "paid off". Which pushing through the confuseing payments costs as well as additional costs, in reality your technically paying more then the phone sells for. So if you intend on keeping your next phone. Just go out and buy an unlocked version. Or get an unlocked international version.
Try baking it?
My wife's v10 started bootlooping about a week ago and is out of warranty. This happened right after doing a FOTA security update. I figured it was due to that so I tried resetting the phone but could not boot in to anything to get it to reset. After extensive searching and reading, I have "fixed" the phone so far. It has been booted up and running for almost 2 full days now. We are not using it at the moment, we had a spare phone so its not like we were going to be out of anything. Instead of the freezer trick (was not worried about data backup), I did the baking trick and as surprised as I was...it worked! Here is what I did if it might help anyone else.
Please note that your warranty will really be void after doing this, especially if anything gets damaged. The information here is reference only and results may vary due to altitude and baking temps (thought I would NEVER put that in a disclaimer for gadgets and software, lol). You may or may not have data loss either, so do not blame me!
You will need to take the phone apart so you will need a small precision set of screwdrivers. Check out the video from the link below to see how to disassemble the phone, you only need to get to the part where the circuit board is removed.

And now...seriously,
1. Pre-heat your oven to 385 F (~195 C).
2. CAREFULLY take the circuit board out of the phone, use the video above as reference.
3. Place the circuit board in the oven and bake for 7 minutes. I set my board on a baking rack so it was not directly on a cookie sheet.
4. Take circuit board out, shut off oven and let sit for at least 20 minutes to fully cool down. Add salt for flavor? (j/k)
5. After cool down, CAREFULLY place circuit board back in and put phone back together.
6. Put battery in and let charge if needed before booting the phone up.
7. Cross fingers and turn the phone on!
We were at a point to where we did not want to file a claim if we were going to end up with the same phone possibly again and have issues so I figured I would try it out. My kids thought I was insane watching me bake a circuit board.
However, the electronics knowledge in me knows this is just enough to actually do solder reflow on the board. From the numerous posts that I have read, it appears that some of the soldering is faulty and sometimes a reflow will fix the issue. Since circuit boards are so small and intricate, it takes extremely serious skill to actually use a solder iron to fix those...so for those of us who are not extremely seriously skilled in soldering, the oven seems to work. Don't get me wrong, I can solder like no tomorrow...but not on circuit boards
So if you have nothing to lose...give this a shot!
I had the same problem, I'm unsecured so I take a repair where a technician and told the hay processor to re-weld it because it got off the board.
Ten days ago, during an ordinary work morning, and without warning, my V10 entered the boot loop spiral of death. The unprompted reboots became more frequent, moving backwards from home screen, to AT&T screen, to LG screen, from where the phone eventually refused to proceed. I bought the phone during the first week of U.S availability in October 2015, so it's past warranty, of course.
I submitted a ticket at the LG website, and shipped my comatose V10 via FedEx an exact 27 miles across the DFW metroplex to the LG Service Center near Alliance Airport north of Fort Worth. The package arrived there the next day thanks to close proximity to local ground service, rather than making a fun trip to Memphis and back.
My V10 returned yesterday. I paid $72 + tax for out-of-warranty replacement of the main logic board, which we surely suspect to have failed because of the well-known factory defect that appears to have affected the V10, G4, and even the G3. $72 is still a fair price for this type of repair on a large premium smartphone. My software and settings were easy to restore after my having number moved back from my wife's old G2 to a new SIM.
Will it last? I hope so.
Your are genius, so does your kid will grow up the same way...
Hi John!
I register this forum just for the purpose saying " Thank You! You are genius"
I followed your step by step guide and brought up my LG V10 to life, which casued by the so called " boot loop" problem few days ago.
I was almost ready to send my V10 back to the LG, and requesting for the replacemnt of the internal board of my LG V10. Luckily, I read your thread, and presume that your assumption is right with logical analysis. Now my phone is working without boot problem, and I successfully bring back my data from the internal memory, too.
Thank you so much, John!

tl;dr: My chronology of the infamous LG V10 boot loop death which got repaired under LG's unannounced extended 15 months warranty. Important lesson learned is make sure to back up all the phone's valuable data (even though I technically didn't lose anything critical).
01/03/2017: I finally experienced the infamous boot loop of death with my AT&T LG V10 yesterday (01/02/2017). The boot loop I encounter isn't due to flashing gone bad or wrong, but due to regular use. My phone wasn't excessively overheating at the time, but I do know that the metallic ring around the power/finger print sensor was warm due to surfing the internet at the time on Chrome. I do have a tempered glass on the phone and a slim translucent plastic cover to protect my phone. What happened was that my phone suddenly just powered off the display screen. I thought the phone just experienced a force close and forced reboot, not that I ever experienced one with the V10, but other Android phones before (i.e., very old ass Android phones). But I waited for the phone to boot up, but it never did. I tried to reboot the phone and then that's when it got to the home screen and locked up. Ever since then, reboots failed to get pass the AT&T logo, but could pass the LG logo.
I've already tried the refrigerator/freezer trick to cool down the phone, but it appears that I'm passed that stage where the phone would not boot pass the LG logo or AT&T logo. The more I tried to get the phone to boot up, the more it will just stall or reset at the LG logo, or refuse to boot up (i.e., speed up its death). Even the charging screen once showed, no longer reaches the charging stage where it shows the percentage of the battery's power remaining through the wall charger or being plugged into a computer laptop. Pulling the battery and letting the phone sit idle (to cool down the internal circuits?) for a while will allow it to come back to life with the boot loop problem or the ability to charge the battery via a computer's USB port. I tried charging with the wall adapter, but that forces the phone to boot up, and render the phone useless thereafter, so I elected to charge the phone via computer.
My AT&T LG V10 (H900 variant) is on Android 6.0 (H90021w00). It's not rooted anymore due to upgrading to Android 6.0 (I updated back in November 2016 here) without issue and wasn't abused (e.g., phone dropped, water damage) for it to cause the boot loop of death. The hardware version (H/W) is 1.0 with the SKU 6084A. Battery manufacturing date appears to be 2015.11.07 (D). The OEM package boxing has DHHS Code MC1, manufactured date of 12/2015 and made in Korea.
I wanted to try and save some data off of my phone, but the phone couldn't stay on life support long enough. Of course, fastboot won't allow me to save data (it's design is to write data only). I did manage to put the phone into download mode (i.e., phone powered off, hold down volume button and plug in USB cable from computer) one time and try to flash an upgrade of Android 6.0 firmware H90021w00 with LG Up, but it failed somewhere after 10%.
Good thing I have Google Photos backing up all my photos and videos, and nothing critical resides on my phone other than auto logins. I'll just have to change all my passwords soon enough if my phone has to be taken away for warranty. I wanted to at least save data and do a data wipe to make sure that nothing falls into the wrong hands. But I now can't do any of the two. I called the nearest AT&T corporate store, but was directed to one that has a warranty center. I will be on my way to an AT&T corporate store later tonight that has a warranty center. Just doing so to avoid traffic. I know my phone has the usual 1 year warranty, and speaking to the AT&T corporate store with the warranty center, I was told that I have at least 80 something days left of warranty. So good thing I'm not screwed and can at least get a replacement phone.
Currently the phone is sitting on my desk charging at a slow ass rate and up from fluctuating anywhere between 12% and 21% to a now whopping 30% power capacity. I want to at least demonstrate the boot looping to AT&T personnel and it's not due to physical damage or water damage. I'll report back what's happening with my situation so that way, anybody else who experienced this situation will have something to go by.
Update 01/04/2017: I read through the freezer trick thoroughly this time and the entire thread. I decided to try it again, but this time, I left the phone in the freezer for a short time (half an hour or so) without the battery. After time elapsed in the freezer to cool down the phone, I plugged in the USB to the phone while having my laptop near the refrigerator with LG Bridge loaded and ready to back up, and then put in the battery. Lo and behold, the phone did manage to boot up all the way to the lock screen, due to various sound cues from the phone (AT&T logo) and USB connectivity (from Windows 7). However, when I tried to unlock the phone, that's when it froze and rebooted. After that, it hit the boot loop and won't get as far as the initial try. So I'll keep trying to revive my phone long enough to get some data off of it and wipe it clean. I still have time with warranty, so I'm in no hurry. Besides, I attempted warranty processing last night and missed the opening as the warranty department closed early.
Update 01/11/2017: I managed to get my LG V10 phone to boot up further than the freezer trick by utilizing the hair dryer trick here. Basically, what the video shows is that one must take a hair dryer, blow dry on the highest heat setting to the bottom of the backside phone up to the point where the phone gets hot, without the battery for over a minute. After that, put in the battery, boot up the phone and blow dry the bottom of the phone and heat it up even further while it's booting. I had to repeat the hair dryer heating process many times in order to stabilize my phone because it would reboot within minutes after I try to initially back up with LG Bridge's LG Backup tool. I did manage to overheat the bottom part of the phone so much that Android denied charging the battery via USB connected to the computer. Further exacerbating the problem was that the battery was so hot, LG Bridge denied backup because it thought the battery charge status was under 30% when in fact, my LG V10 showed at 49%. I did get the most important file that I was after on my phone after many tries (kept rebooting on me), but I'll persist to back up the entire phone in case I needed something else before turning this phone over to AT&T warranty service.
Update 1/19/2017: As much as I tried to back up my LG V10 and wipe afterwards, my attempts were futile. The phone couldn't stabilize enough after reaching the home screen, and would reboot shortly thereafter. At least I got what I've wanted. When I kept trying to revive it with the hair dryer trick, it just wouldn't go pass the boot screen most of the time (i.e., LG logo or AT&T logo). It even got to the point where it would turn on slowly (i.e., there's a delay booting up when power was pressed on). So at this point, it appears that the boot loop of death is sinking in further into my LG V10. I also tried the freezer trick again and then going back to the hair dryer trick when the freezer trick stopped working, although not back to back, otherwise that would provide temperature shock to the components. The freezer trick did manage to get further, but it only happened twice where it got to the home screen and then rebooted. Note to those wondering if condensation would trip or activate the moisture sensors on the phone and the battery, it does not when you take careful steps of taking the phone out of the freezer and putting it into the refrigerator and then take it out, letting maybe 10 minutes pass by for each step of temperature transition so that the phone's temperature can get to room temperature without condensation buildup.
Anyways, I decided that I've spent way too much of my time trying to revive my phone to back up data that most likely I wouldn't need. I went the route of sending my phone to LG for repair instead of going to AT&T store and receiving a refurbished LG V10. I'd rather have my phone repaired by LG and receive my phone back with the repaired hardware than to receive someone else's LG V10. I based my decision on this thread here over at Android Central where someone sent in their phone for repair, got theirs back with a clean start (i.e., don't expect LG to either back up your data or reuse your memory storage as no personal data was saved). It is good to note that LG has extended LG V10 warranty of 1 year (12 months) to 15 months. I'm pretty sure LG granted a 3 month warranty extension on LG V10s due to the boot loop issue. I didn't realize I got the extension until thinking back, when I called AT&T warranty center, they told me I had about 86 days of warranty left, which is about 3 months extended from my 1 year of warranty when it ended. The phone was bubble wrapped (removed back cover, battery, SIM, microSD) and shipped off in a small box that I re-used from another item that was shipped to me. Shipping carrier is by FedEx Ground that was paid for by LG, being shipped to LG's repair center in Texas.
Update 01/24/2017: The phone has arrived at the Texas facility yesterday (Monday) according to FedEx, but the status of my repair hasn't been updated anymore than giving me estimated delivery date of 9 days. What's odd is that LG didn't update the received date at repair facility field and have deleted my FedEx tracking number.
Update 01/25/2017: LG updated the repair status last night which pretty much acknowledged item received, diagnosed, repaired, and prepared for shipment back to customer. The repair was "Swap Board (Main/RF) : Others". I should have the phone back on 01/28/2017 and will update then accordingly. It appears that LG probably replaced the entire mother board which would include the 64 GB of memory holding user data, among others. Considering that others have reported of receiving a freshly formatted phone, I would expect the same once the phone reaches back to me. I would highly doubt LG went the extra length to migrate data off of the failing motherboard onto the new one. It would be nice if they did.
Update 01/28/2017: I have received my phone today via FedEx Ground shipping, and they delivered on a Saturday. The status of my phone was factory reset. I can tell it was factory reset because I still have the unlimited tethering (hotspot) enabled from the previous rooting (Lollipop) and then went to Marshmallow and losing the root, but still have unlimited tethering. Also, Android OS is updated to H90021x (from the previous H90021w00), build number MRA58K, with Android security patch level 2016-11-01. You will need to set up the phone just like you did the first time. They also removed my tempered glass and left a narrow sticky film that doesn't cover the entire front screen glass that can be peeled off. Good thing I have an extra tempered glass for the V10. The phone came back with the same serial # and ESN/IMEI that I've sent to LG. If you're like me trying to migrate data from one LG phone to another, it's best to use the LG Backup in Backup & Reset under Settings that's found native in the phone. LG PC Suite and LG Bridge won't work with Verizon's LG G4 (VS986) on Windows 7 for me, no matter what I did (installed many LG G4 drivers, including Verizon's). Some backup apps, such as LG Backup (Sender) and Super Backup & Restore do not back up everything, neither does the native backup LG Backup in the Android Settings menu.
Update 02/03/2017: What appears to be a puzzling action on my repaired LG V10 is that I'm going to take no chance and back up my phone in case I end up losing data again. What happened earlier was that I was surfing the Internet with Chrome, reading up on a news article, when I was prompted to Miracast and enter a PIN. WTF? I ignored it a few times and then it got to the point where my phone was unresponsive with the Miracast prompts, but I was able to force my phone to reboot. Upon reboot, I noticed that the phone loading up was sluggish and not typically responsive. I decided to shutdown my phone to prevent further irreversible problem in the future (hint: boot loop). I waited for my phone to cool down for perhaps a few minutes before I powered on the phone again. This time, when the phone booted up, it was responsive as it normally has. Before all this happened, I didn't use my phone excessively nor extensive in a short period of time. I really have doubts that LG really applied a fix to their faulty connection problem and just used a replacement just to pass by.
Update 02/04/2017: I received an e-mail from LG requesting my feedback with respect to the repair. I gladly answered the survey, gave them good credit with respect to the repair itself, but when it comes to the quality of the LG product, they took a hit and I expressed my concern with respect to the boot loop.

You may not have to change your passwords. Depending on what hardware is damaged they will likely trash the whole board. If any part of the chipset is fried or damaged in some way, your safe since everything is on a single chip. So if it is a hardware failure on the chip, then all your stuff thats on there is going in trash to never see light of day again.

Big thanks to you, LG V10 baked back to life, LG BackUP running 57% !
Its too bad I didn't know about this before hand. My phone just bootlooped last Saturday without warning. I contacted my carrier but I was literally 4 days over the warranty period with them. Contacted LG, and they told me they couldn't either repair or replace my phone because its an international model and they did not have the hardware for international models(no clue why they couldn't replace it, unless they stopped manufacturing this specific model). Either way, I didn't worry too much about my files as I had contacts and texts on the SD card as well as Google, and my pictures and media where stored on my SD card. However, for the latter, I didn't realize that you could only 'unlock' files with the same phone you locked them with, so they were sitting on my SD, completely useless. I also lost all my progress on Yu-Gi-Oh! Duel Links because apparently Konami are idiots that don't realize they can link progress to a Google account rather than going through their own service.
I just got done disassembling the device and heating it up with a heat gun. I had nothing to lose, so why the hell not? Surprisingly, its managed to remain working just fine for 2 hours now. Managed to recover my locked files, my Duel Links progress, and my Authy backup. Still, I know it will eventually happen again, and I'm still under contract for another year so I'll be forced to buy another phone and still pay for this "almost" paper weight. Here's hoping that Class-Action Lawsuit actually leads somewhere and LG deals with this fairly.
@johnkirchner
You saved me couple of hundred of bucks.
I almost made a deal to buy a new phone and for the sake of wasting time, i tried your method.
I am shocked to see my phone in working again.
You are amazing.
Pretty sure my phone isn't in warranty anymore anyway since it's been over a year since obtaining it (sadly it's not eligible for an upgrade until January of next year, since pay-off rates are now every 2 years minimum), but I'm hesitant to try the bake method -- especially since I don't have my own oven currently, being that I'm staying with someone else's family currently due to economic situations.
With that said, I can get to the factory reset option by holding the Vol-Down + Power buttons, I just don't want to lose my data. I know for a fact USB Debugging is enabled, because I always enable that pretty much first thing when I get my Android phones, but I can't get ADB to recognize it. Windows always shows it as a "USB Charge Only Interface". I know there's a way to use ADB to backup data ("adb backup -all" should work IIRC) so I was going to try that first, then try the factory reset and see if it helps at all. Any suggestions?
If I can even get the phone to start up at all, just long enough to take it to AT&T, I can just trade it in for a new phone. Otherwise I'm stuck paying over $200 more for a phone that doesn't even work anymore anyway, just to get a new one.

We were at a point to where we did not want to file a claim if we were going to end up with the same phone possibly again and have issues so I figured I would try it out. My kids thought I was insane watching me bake a circuit board.
However, the electronics knowledge in me knows this is just enough to actually do solder reflow on the board. From the numerous posts that I have read, it appears that some of the soldering is faulty and sometimes a reflow will fix the issue. Since circuit boards are so small and intricate, it takes extremely serious skill to actually use a solder iron to fix those...so for those of us who are not extremely seriously skilled in soldering, the oven seems to work. Don't get me wrong, I can solder like no tomorrow...but not on circuit boards
So if you have nothing to lose...give this a shot!

I gotta give it to sir john. I was hesitant to bake my board, but i figured i really wanna toast it anyway so what the heck. 15min after i turned off the oven i reassemble my v10, and it now boots onto home screen like magic.
Salt to taste

Hi John!
I register this forum just for the purpose saying " Thank You! You are genius"
I followed your step by step guide and brought up my LG V10 to life, which casued by the so called " boot loop" problem few days ago.
I was almost ready to send my V10 back to the LG, and requesting for the replacemnt of the internal board of my LG V10. Luckily, I read your thread, and presume that your assumption is right with logical analysis. Now my phone is working without boot problem, and I successfully bring back my data from the internal memory, too.
Thank you so much, John!

Thanks john
After limited temporary success with the hair dryer method your post led me to the baking method. It took 3 attempts at increasing time and temps . Started at 385 for 7 min. And it tried to boot but not. Then tried 385 for 10 min and it made it to just past the red round hello. Then I went all in. 400 for 13 min. With a dash of salt and a sprinkle of mesquite flavor. I'm in Kansas city... we love our bbq...what can I say? Anyhow, it sure as hell worked.... can't believe it but yes indeed... and it makes for a great no **** kinda story... thanks to all who shared here... oh btw, toothpaste does in fact make for a great heat sink..... paddle faster I'm hearing banjos
To give some context, my S10e (Verizon SM-G970U) decided to boot loop out of nowhere. Since this happened, I have factory reset the phone, no success. I brought it to a local repair shop who said they couldn't fix it. Now I have flashed the phone with Odin and despite the phone being flashed it STILL is boot looping. At this point, I'm assuming something went wrong with the hardware but I don't even know where to start with that. If anyone has any suggestions I would greatly appreciate them.

If it is a hardware issue (which sounds likely), there's an old electronics trick you might try: Power it off, put it in the refridgerator awhile, take it back out and power it on. This has work'd for me with stereo components, for example, as well as a phone. It once revived a hard disk drive long enough for me to capture important data. Oh, but the phone this has brought back for me, an S10e BTW, works only while still cold and has issues with charging while its temperature is low. Still may be worth a try.

Wow, I just did this and to my surprise it worked! Prior to this, I wasn't able to get past the Google sign in page on start up (on good attempts) but now I was able to get it all the way to the homescreen and even install some apps before my battery died. Any idea of what this could mean for the actual hardware? I.e. this means the battery needs to be replaced etc

Great; glad it work'd. Did you attempt to charge it while it was working? Mine actually took charging after warming up only a short time, once. Got it back all the way to 100% charged. But then it quit with dead black screen, and now revives only for a minute or two.
In the old days of individual transistors, we used to turn on a non-working electronic device and blast a shot of freeze spray on various components until the device started working; even with IC (integrated circuit) chips that have lots of transistors. This way, we knew which part needed replacement. But with today's phones, you replace the entire circuit board because the soldering is done by machines; it's too finely detail'd to replace one chip.

I haven't tried charging the phone when it's on. Only when it's off and has returned to room temperature. Seems to me that about an hour in the fridge equals about 5 minutes of screen on time until the phone heats up again.
As for the internal component's you bring up a good point. Even if I were to determine what is causing the issue, I don't have the will/technical know how to buy the parts and do it myself. Outside of just replacing everything, in which I'd just buy a new phone haha.

That's what I did. Look'd at lots of possibilities, ended up buying another S10e.
