I thought I'd share my experience with this, as I've seen posts in the past relating to a water damaged phone boot looping and I don't think I've seen a proper solution given.
First thing's first, this advice is in relation to a very specific type of boot looping. Nothing to do with rooting, or software bugs. This is boot looping that has come about as a result of water damage. It may not have been long, maybe a couple of seconds in the toilet or some brief rain exposure. Whatever it is, you know your phone has been exposed to some water and it has begun boot looping. There will be no way to get out of it, as the phone boots for 2/3 seconds max before looping all over again. Even when you go into recovery, same thing, automatically boot loops.
Most people, including the official HTC Service Centre, will tell you the motherboard is fried and needs replacement. Whilst it is possible that may be true, it isn't guaranteed. It's an easy way out for HTC, as they can charge you an extortionate price for a new motherboard and not have to bother going through the work of taking the phone apart to find out what is wrong.
The solution may be much simpler - the Power Flex Cable. This is a very small cable that goes along the top of your phone. WHen water damaged, this cable can become damaged, causing a constant boot loop. The reason being it constantly tells the phone the power button is on, causing a constant on/off cycle. In this instance the motherboard is fine and you can get a replacement Flex Cable for less than £5!
There is an easy way to tell whether the Flex Cable is the likely cause of your looping. When the phone is looping, hold down the down volume button only. Don't touch the power button. If your phone still goes into recovery (then loops again) then it is entirely possible your Flex Cable is damaged, not your motherboard.
Next step, order a Flex Cable (they are easy to find). When it arrives, you will need to open your phone (there are guides on YouTube for this), detach the motherboard and replace the Flex Cable. An advance warning, this isn't easy and you have to be extremely careful. One bad move and your phone is history. The motherboard is delicate. If you look around the internet you will find guides which show how the HTC One X is configured. Note that the Flex Cable is behind the motherboard and quite awkward to get off. I would post a couple of links but as a new member I'm not allowed! PM me and I'm happy to share some helpful links though.
You'll know quickly if this has worked. When connecting your phone it will no longer loop. Let it charge for a little while, then power on and hope for the best. If the Flex Cable was the problem your phone will reboot, and you will be able to use it and get your data off.
Note that water damage can have long lasting effects on a mobile phone. Whilst this may solve the problem for a while, it's entirely possible your phone will fail at some point down the line. Prepare for that and make sure you back up accordingly. The above advice may give you a lifeline in getting data off your phone, though, and being able to use it for a little longer. I know that when I was looking around the net I only found this advice by chance, and I think it was on a non-phone related forum. This advice may exist on the forum somewhere but if so it isn't so easy to find. I hope somebody may come across this topic when trying to fix their water damaged phone and find it is the solution.
Good luck!
Same symptoms, but no water damage
Hey man,
Thanks a ton for your post. I have the same issue, as in it won't stop booting at all. However, mine didn't happen because of water damage, but when I tried to do a factory reset (the phone was only on 5% charge so I'm not sure if that screwed it up). Do you think it could still be solved with a flex cable? I tried holding just the volume button down, and it does go into the bootloader so it seems pretty much exactly like what you have described!
Cheers
My only experience with replacing the flex cable comes from water damage, I'm not sure whether a software fault (as this appears to be) could have any effect on the cable itself!
When you get into the bootloader screen, does it just cycle all the way through to fastboot without allowing you to select any other options before rebooting? If so it would suggest your phone thinks the power button is constantly pushed down, which is suggestive of a power flex cable fault.
These cables are very cheap to buy, so if you aren't able to do anything else with the phone it's definitely worth a shot, even if it doesn't work. Just remember that opening the phone voids your warranty, and be careful if you do attempt it, as the insides of the One X are quite delicate. It would be very easy to break something!

I had to replace my power flex cable when I was changing my battery as I accidentally snapped it.

It's very easy to do, the flex cable is a fragile piece. There are quite a few parts inside the HOX which could easily snap, which is why I always urge a lot of caution when opening the phone up!

Thanks. I've already taken the back off and noticed some broken bits of plastic...from the back....but I did notice a bit of ribbon that looked a bit screwed up....I'm gonna take it to the gizmo wizard to fix once I buy a new power flex cable.
Good luck!

Old thread I know but thought it was worth adding that with a water damaged phone the issues can result from the fact that tap water contains minerals which can leave a conductive residue when it dries - can change resistances, cause shorts etc. What I've done previously is used isopropyl alcohol (tape head cleaning fluid) with a toothbrush on the motherboard. Brought a phone back to life. This removes the mineral deposits and cleans everything. Had to remove the metal covers from the mobo first though. If a phone is basically dead or not working right after water damage then it's worth a go. As de4life says, just need to be super careful on the HOX with all the delicate ribbon cables.
Indeed, the phone should be thoroughly clensed if possible to wipe out any corrosive liquids left behind from the water (especially if it's dropped in an ocean). The effects of corrosion can be very slow and potentially last for months.
M8 please reply to this all the flex cables that I found are 40$+ can you give me a link for one as you stated that would cost 5 pounds
It worked
It worked! I replaced the power flex cable with a spare one on my HTC One X, previously damaged by being sucked by my one year old son - water damage.! It worked!
Many thanks to you man!

Thank you very much for typing this out! My Google Pixel OG (2016), which was made by HTC, experienced the exact same problem. I have just fixed it by replacing the power flex cable like you suggested.

Hey guys-- got back from the t-mobile store and they told me the data port is dead (from water damage). It turns on with a fresh battery fine, but apparently I'm getting an error code. That code is probably that the data port is messed up because I can't charge my battery. I'm assuming I have to replace it. Does anyone know of a video tutorial or something that will show me how to do it?
thanks.
the chances of the data port being physically damaged by water is very slim- I think they are trying to tell you the circuitry is faulty. If you had ripped the charger out and bent or broke the port, then I could see it- but water cannot bend or break that way and corrosion is unlikely unless its been sitting a while.
Back to the original subject though, I just replaced a faulty USB port on my friends Moto Q. It wasnt bad, but you need a very small pencil iron (I use a station) and good eyes, otherwise you will bridge the tiny connections and be fubar'd.

Where did you find the port to replace it with...
find a bricked one on ebay or something..or someone selling one with a cracked screen etc...use it for parts
welp, i've never soldered... guess you gotta learn sometime. ports are bout 25 bucks... Guess I have a new hobby. Or maybe I should just buy an external battery charger... soldering sounds more fun though. Yeah, what i meant by getting an error code is when i plug in the charging cord into the cell phone, I get a red light instead of yellow/orange. But, I have to push up on the cable where i insert it into the port to get anything. So, its not dead, but either dying or drunk....... drunk from oil.... which it swam in... and got sick from. vegetable oil, not motor oil... which would be a waste of oil. Anyways, thanks for the replies and if you stumble upon a vid for the dash, please post it. I found some on blackberries, but not an excaliber.
sorry browser problem (double posted)
my friend sourced his usb port from Mouser (P/N 538-67503-1020) for $1.12 each. I still have one (he got a spare) but I dont have a dash to take apart and compare the pins. I assume they are all the same generic port, but the pin spacing could differ
http://www.mouser.com/Search/ProductDetail.aspx?qs=7zcQ9RRVJlhHWuXYKEhKMg==
that's pretty sweet speed. I bookmarked that webpage (dunno why really). I could just always link from here; but anyway, I received a new battery that I ordered before the geniouses at t-mobile told me that a red light is an error code, my old battery is perfectly fine, my data port is broken, and no... a new battery won't fix it. *** what's my point you ask?***
They don't know jack fecal matter. I just popped in the new battery and 1) my phone turned on, 2) my charging light turned orange, 3) my plug doesn't need adjusting to charge the phone, and just now 4) my phone has signaled to my through a pretty green light that the new battery just finished charging.
So, to recap, the guys at t-mobile said my port was fried and that all my problems were due to that. My theory was that oil (and come to find out water) damage caused the battery to malfunction and thereby refused to allow a current to charge it resulting in the errors. Turns out, I was right.
Thanks speed and all for your replies. If I need a cheap miniusb port in the future, I now have a good source. Now, Anyone know if a new lcd will fix the splotchy marks on my screen (look like dark puddle spots). I'll post a pic in a new post in a minute.
Yah you can grab a new LCD off ebay (fairly cheap) and then go to youtube and youtube "fix dash screen" and there is a tutorial on there that will guide you on replacing your screen.
just make sure its the lcd thats the problem- the outer clear part that you can touch is separate, and comes with the case. Mine are scratched to hell on both my Dash's but I refuse to buy new cases to fix them
i dunno what's up anymore
I don't know what to think of this thing anymore. This morning it wouldn't turn on, even though I had the green light on the device as it was plugged in all night. So, I kept fiddling with it hoping it would turn on so I could have ATT do a remote hard reset. Well... it wouldn't cooperate. So, I left it alone. Then this evening I was about ready to bury it and I tried the power button one last time and it turned on. But, the battery was really low and I got the red light again when I plugged it in. I guess the battery got a bit of a charge in itself just sitting there. So, perhaps the t-mobile guys do know what they're talking about. Well... i did actually get the orange light while it was on for that sweet minute, which should mean its charging, but I guess its not actually charging the battery. I suppose the last way to go is external charger. I'll probably pick one up off ebay for 15 bucks.
ive been having a problem with this phone for a while. it has a problem with turning on and statying on. i will set it on charge while its powered off for atleast two hours, but as soon as i turn it on it will last for about 5 mins and turn off.
i first replaced the battery and it has the same problem. so i replaced the charging port and it was working fine for a few weeks and now its back to the same issue. i cant even get it to charge now
so just trying to figure out what kind of other components it could be
Disclaimer: You're at a more advanced level than I am. I've never done phone repair, and I don't know enough about phone hardware to say if there are other components that could be responsible. I'm a software guy.
That being said, I'll chime in with what I do know, on the off chance that it's actually helpful.
When computers get too hot, they do an automatic thermal shutdown to try to prevent permanent damage. I assume smartphones do this as well. You're on XDA, so there's a good chance you like to tinker. Did you overclock the phone? Overclocking generates more heat, which could potentially lead to a thermal shutdown or permanent damage. Or you might be using or storing the phone in a hot environment.
Have you tried using a different charging cable? Maybe the cable or its connector went bad. You could also test the cable with a different device. Maybe the wall outlet, etc went bad. Did you check the connectors that the battery attaches to, to make sure they're clean?
When you opened the phone to replace the charging port, maybe you didn't put it together quite right, so over time something came loose or got pinched. Desktops and laptops use various types of adhesives such as thermal paste, and computer technicians have to remember to reapply new adhesive when putting a machine back together. Maybe phones use some adhesive too, and maybe you forgot to reapply it?
Hopefully someone more knowledgeable about phone hardware will chime in, but the Incredible 2 section of these forums has been a ghost town lately. That's why I'm giving my two cents. If it were me, I'd just buy a new phone.

well i greatly appreciate your lengthly response. to be honest, it is my mothers phone, which is why i want to try and fix it. i gave her an iphone so she really doesnt need this phone but i would like to figure out what is wrong because i do like to tinker with things. i have tried different chords, wall outlets, usb ports on the pc etc. i will reopen the phone to see if everything is back together, because thats the only thing i can think of from what you mentioned.
thanks again. if anyone has had a similar problem, let me know
sounds like you're either having a battery issue or need to replace your charge port on your phone. its a really simple process all you do is order the port from like amazon or ebay and the old one on your phone just unplugs from your phone circuit board there actually is a tutorial forum in the development page for the droid incredible 2 that gives you instructions on how to do this. hope this was of some help to you and if so please click thanks.

The OP already tried both of those things.
Oh ok yeah i just noticed where he put that. Hardware problem maybe. Im more into software myself than i am hardware.
MINE TOO! Omg
This... it's too much. Okay, a month ago the damned power button got too hard to press in, which should have been a warning that the hardware was getting faulty I suppose. But I downloaded an app that let me use the volume button to turn screen on/off. (I won't say which because I half-blame it, unfairly, for killing my phone
(Sorry, I'm still —mourning! the death of my phone I guess.)
The app was an ugly solution, I guess, but it worked. (I couldn't turn the screen off easily, so I set the screen-off to 10 seconds.) And I hadn't used screenshots in a while so that was no big deal; and my ROM could get me to Recovery easily enough, so screw the power button, right?
But then last night, my phone STOPPED CHARGING! I did a batt pull, tried new cords; turned off every useful app. I even went back to stock ROM, which (even though plugged in) left me with 20% batt. Might as well have bricked it, I guess.
Nothing worked. I was able to turn bluetooth back on so I could use my Air Droid acct to get my on-phone pictures, at least (everything else is safe on the SD), and then I charged it overnight in the wall and hoped for the best.
I was pretty thrilled to wake up to 100% charged! —For a few minutes. As soon as I unplugged it, it started discharging fast, and then not even the wall charger stopped it from discharging.
After brooding, for a few hours, I called Verizon tech. The tech (VERY nice, admittedly) said my Dinc2 was just dead. (Damn they're good: he was more sympathetic than a doctor delivering bad news!!) —But I feel so lost. He offered me a DNA or a Dinc 4G (and some motos and crap), but said my Dinc2 wouldn't be worth fixing. He said the power button alone was a PITA, but the dongle thing you plug the charger into was likely the problem, AND it might be the battery. Maybe he said other problems, but ultimately he suggested some pre-owneds he had for sale (I'm trying to keep my unlimited data plan), or try PhoneKarma.com. (He said he didn't recommend eBay, where they have Dinc 2s, but I'm not sure why.)
So ...do Dinc2s just have power issues after (?) 3 years? I guess that's a pretty good lifetime, but boy is it depressing. (I know — hooked on a damned phone. #Sucks.) I mean, it would be stupid to fix this one, or buy another one, right?
@Trebuchette, no matter what machine you use, rechargeable batteries do not last forever. Order a new battery from Amazon or eBay and you should be fine. They're pretty cheap and easy to replace. http://www.amazon.com/HTC-Incredible-6350-BTR6350B-Packaging/dp/B0064SI3QA
A case might make your power button easier to press. The OtterBox Defender is an excellent case that you can get for $15 used (very good condition), if a new battery successfully fixes your problem.
Hey: might be worth a shot! I did try another batt, but it was older too. And I didn't think of an otterbox at all, tbh. Thanks! Might be worth a try!
Hey: does it matter much if my USB cable is LG or whatever? I tried several different USBs too, but I'd been using this LG one (no idea how!) for probably about a year.
No, the brand of micro USB cable should not matter. It's a technical standard.
Don't buy a case until you've verified that a new battery actually fixes your problem. If a battery doesn't fix it, it's only a few bucks lost. In that case, I would then get a new phone.
i just came back to this thread after i basically put the project on hold for a while and wanted to see any new suggestions. so after leaving the phone alone for two months, i pluuged the phone in and i saw that orange ligh indicating it was charging. so far so good, im not using it as a primary phone which is good, but that would be my suggestion is to give the phone a rest for a while
EDIT: yeah scratch that, its doing the same **** now
ok so... the store broke my lcd while they were trying to remove the digitizer... and now i am looking at ebay on which lcd+touch assemlby to buy and i have a question. are the sony, acer and sharp lcd versions compatible with all one x mobos? i did some research and found that the sony version is the best (so they say)

Hi,
The Sony and Sharp are not compatible with each other( I've tried to replace one with the other), I've never come across the Acer LCD in Australia so I'm not sure. If you don't know how to tell the Sharp and Sony apart, the Sharp has Green backing on the flex cable, while the Sony is sort of orange with a few yellowish stripeson the back of the LCD flex cable. Sorry I couldn't find any of my photos which show the difference. I would recommend buying the LCD/digitizer combo and a separate midframe to mount it on, as it comes with new 3M adhesive, but you may also have to add a few TINY drops of instant adhesive, I say tiny as too much will press out under the digitizer and will show up, but I have found that without it the digitizer will lift from the frame eventually due to the tight fit of the frame in the rear shell of the HOX.
Hope you go ok!

ok tnx for the info... and i was thinking i can just order whatever. i checked the panel_type in the last_kmsg and i found that i have the replacement screen for which nobody knows who makes it. but it is a warm panel so it probably is sony... but i have to rip it apart to be certain

That's the only downside - having to pull phone apart to check which one you have. Also another tip, phone need to be on to change LCD's, boot phone up with it apart, then wake up with power button on old screen, then sleep with power button, change screens then wake up again. There are plenty of vids on youtube to help, if new screen doesn't activate, check flex cable is in square and all the way - have had this problem before also.

I replaced my screen, but I powered down when removing the screen, and putting the replacement in. Now neither will light up. How do you solve this?
There are no guarantees with this, but try pulling the battery out for a minute or two. then with the original screen in, boot up and let it get to the lock screen wait for the screen to sleep then press power button to wake up then again to sleep. when the screen is sleeping try changing over the screens and then press power button to wake again. this is assuming that the screen displays on startup, but even if it doesn't try this process anyway. if it doesn't work, try doing with the new screen back to the old screen after pulling the battery. I have only ever come across this once, but it wasn't from powering down during a screen change, but pulling the battery seemed to fix it.

I tried that, didn't work. I think I know the problem now. after searching on multiple forums, I think it's the 220 coil. A lot of people have had a similar issue, and they say they've solved it by replacing the coil. What I want to know is, how I managed to short the coil in the span of a few minutes, despite having used the same screen as the cracked one.
It is possible to do, although they can go for no reason, I recommend taking it somewhere to get coil replaced, it is a very fiddly job and you need to have a steady hand and the right tools (hot air gun) although my father managed to do one with a standard soldering iron, although it wasn't the best job. you risk damaging other components also if they blow off the mainboard (if you can find them), worst case scenario is the display ic has gone - that one will have to be done by a professional.
what a sh!t phone
we tried to repare it 2 years ago.
but failed.
so i just the pieces to gether wanted to see if i can fix it.
still not lcd just touchscreen (and now im not sure if i even have touchscreen lol maybe i broke that to now not sure
anyway sucks i have a brand new lcd touchscreen with frame we bought back then. and its even the right screen a green flex cable like the original one and still noting so i guess i broke the 220 chip thing how dont know. but not sure if i can replace it sucks it was a good phone
is there any help a easy fix? or do i really need to soldern that chip i cant sell the phone since there is personal data on it contacts and pictures (i guess dont remembrer)
It may still be replaceable, if it's been sitting for 2 headed is the phone taking a charge? It needs to be on to change the screen. If it is charging and booting up, and the screen still won't work when being changed try doing a hard reset by holding the power and volume down button until it restarts - have had advice by someone who repairs phones for a living that this should reset what the phone is looking at for hardware and you should be able to do screen replacement. Failing that chances are it's going to be dead. Not much point in selling it these days as they aren't worth much these days. If the phone won't start the battery may be dead flat. The phone needs some voltage to run its charging firmware, you can try to get it charging by leaving on charge for 10 min or more, even if no charge light, then hold power/vol up/vol down at the same time to recalibrate the charge circuit, it may start to charge after this.
Let me know how it goes, I wouldn't spend too much time on it, unless it's now a project..

ow volum down? okay will try that. but i think i killed it lol cause the charging light wont come on anymore lol
it was just a idea that poped up in my head, that maybe i can save it so i friend can use it but i think i will just trow it away lol or something will give it a shot and see. will report back
nvm it's dead it wont even boot lol. i think i burned sometime lol that little cable that onder the battery thats conects the botem part with the other fliped out 2 time and 3time it smeled burned lol nvm
Sounds like it may have shorted, a replacement is fairly cheap , just depends on how serious you are about spending money on it.
I forgot to mention that when calibrating charge circuit with power/vol up/vol down all held down at the same time, they need to be held down for at least 2 minutes.

nvm i think i fried the cpu or something lol it wont turn on anymore.
i trew it in the bin
Probably the best result, it's probably cheaper to to buy a second hand one and also cause less aggravation when you can't work out why it won't work. You could always sell the replacement screen.

dont think i will sell it i mean who would buy it? lol but guess i could try for like 20euro or 10 lol.
and have 2 batteries for 10 or 5 euro lol
have 3 backcovers also 2 white and 1 black.
we bought every thing to repaire it but yeah.
could maybe sell some **** but pff dont knopw. (its my oncles old phone will ask him (maybe sell every thing exept de motherboard)
That's what I'd do, try and sell it for parts minus the mainboard. If that doesn't work, put it away somewhere and if you come across a dead one cheap, swap the mainboards out (providing it has the same screen - that's a given). Good luck with whatever you decide to do. :good:
Hey guys,
So i flooded my phone, dried it, left in rice for 2 days and now when i connect it to my charger the screen goes up after a minute or so but its not charging. My screen shows battery icon with a bolt inside and a zero below, or battery with a cable inside and zero below. Any idea what can i do to fix this? I can boot to bootloarder mode, but when I'm trying to boot to recovery/other modes it goes back to 'charging screen'.
Thanks in advance!
The battery is eeprom controlled so you probably damaged it when teaching the phone to swim. Flashing will do nothing for it.
Putting the phone in rice is a bad idea as it isn't as absorbent as you think. You should have left it over a radiator for a week or so to evaporate the water before even thinking about switching it on, but by then the damage was probably already done.
If it doesnt start working in week or so then expect it to be expensive to fix.
Beamed in by telepathy.
Not sure what eeprom is, but if its in the part below, then i could replace it myself with no problem. What are Your thougts? I know that more thing may be broken, but if it would go back to life i would be glad because I don't want to spend money on any new phone, maybe apart from S8/pixel but its expensive as hell.

If i couldn't repair this bad boy then I would probably go with 6s, but I'm not sure if I want to make the transition to iOS.
Cheers and thanks for previous reply
Hi all,
I have a general hardware problem with my Samsung Galaxy Tab S4. Maybe someone here has an idea or tip for me.
I still used the factory software without any rooting or unlocking the bootloader. So everything original and up to date.
A few month ago the tablet began to restart in the middle of using it. At the beginning it happened seldom, but then more and more often. Also during the restart new restarts happened more and more often, so that it took several retries, until it started again. Now it is not usable anymore, because it is not running longer than a few seconds before the next restart if it happens to boot completely at all.
I was able to make a factory reset but this didn’t solve the problem.
My first theory is, that this could be a problem with the battery, that it is slowly dying and had more and more problems to hold the voltage. But the problem also exists when the power supply is connected. So I am not sure if this rules out the possibility, that this could be cause by the battery? Does somebody know how this is internally wired, if a broken battery could still have a negative effect when the power supply is connected?
Do you have other ideas/advices, what could be the problem or would could be helpful to do?
Thanks in advance for any help.
Best
The USB power input can't sink enough current to boot it or even run it without the battery acting as a reserve during peak usage spikes.
Replace the battery and go from there.
Thanks, then I will try this.

Hi Vertex, have you tried this already? I have pretty much the same problem and the battery was also my first intuition, but I don't know if buying a new one is worth it. Thanks!
Hi,
unfortunately I didn't had time to do it yet. I want to change the battery myself and for that I will need time and somebody to borrow me a hot air gun, because everything is glued together.
I will report, when I have done it but it will be at least a few weeks.
Alright, so I'll probably try it sooner, I'll update after replacing the battery. Also, if you haven't tried it yet, you might want to try just disconnecting the battery from the motherboard and connecting again after like 20s, I've read that it sometimes resolves this problem, but it didn't work for me. Fortunately removing the back lid of tab s4 is pretty easy, I used hairdryer, so with heatgun it should be even easier.
Thanks for the tips. I am currently on vacation but when I am back I will also try with a hairdryer.
Any additional tips for removing the back lid to somebody doing it the first time beyond what you can see in the youtube videos? How do you glue it back together?
Hi, sorry for the late reply.
I have eventually replaced the battery, and nothing changed unfortunately… I did a factory reset, etc. However I also had an issue that you didn't describe in your original post, which is that USB connection is not working, it only charges the battery, when connected to the PC while booted it's just not visible at all (tried with several cables, two computers, on windows and linux), when in download mode it kind of shows up, but it's not recognized and no drivers or any solution that I've found are working, so I don't know if it's still hardware problem something with the USB related parts or something in the system on lower level. Well, I'll be trying.
About the back lid. Beyond YT videos only thing that comes to my mind is patience. About the glue, you have few options and it depends a bit on how removing the cover goes. 1) glue stays in the more or less same condition as before removing the cover - that's how it went for me - in that case you can just reuse it, just by closing the cover and pressing it down for some time, it's probably not as strong as new but for me it worked just fine, especially if you use a book cover for the tablet there won't be a problem.
But if the glue came off, wrinkled a lot, or just doesn't stick anymore, 2) you can either use a special epoxide glue often with signature like T-7000 or T-800 but if you just look for a glue for smarphones you'll easily find it. Or 3) Buy a special sticker for this exact device which has a specific shape, it's pretty much the same thing as is used by manufacturer.
