Water Damaged Desire, but still loads bootscreen (but stops there)

My wife dropped her phone while getting the youngest out the bath.
She brought it to me and I left it in a warm place to extract any water.
The phone now powers, surprisingly but only gets to the HBOOT menu page, I cant select anything like up / down / power etc, so seems stuck.
I suspect the ROM has been fried, at a minimum. Is the phone recoverable?
Thanks

Strip the whole phone down. (There is a tear down guide with pictures somewhere on these forums for it)
Then clean it/ leave it to try for a few hours and then put it back together and see if it boots up.

Thanks. I dont have the tools to open it and it voids any warranty that 'may' still be available.
Ive left it overnight above my PC's exhaust fan which seems to have worked. Will be trying to boot it soon enough.
If its 'stuck' at the HBOOT screen, what are my options? Seems like the hardware still works but the software may be corrupted.

Its the same as before - stuck on the HBOOT screen. The power button works, it switches on, but even once in the menu on the default which is Fastboot, it doesnt allow me to select that. The power button seems not to work in this menu.

was everything completely dry? best thing was probably not to turn it on for a day or 2.
maybe try stick it in a rice bowl or something for a least 8 hrs.. (rice can absorb water very well).
failing that send it back to htc?

I think she had powered it when it was still wet, this is probably where damage could have happened.
I believe it to be dry now - there was little sign of water and the vapour around the screen area is now gone too since sitting over my PC's warmish fan.
Question is, almost forgetting about how the damage occurred, what are my options for getting a new BOOT loader or similar loaded, knowing that the phone does not boot. Can I make a gold card and update the phone, anything else?
Many thanks.

The volume up button has started to work, I can scroll through the options - what now?
Seems if I take the memory card and make a gold card, I may be able to recover the phone or am I missing something?

It seems to be working OK again. Im not sure what I did, I tried 'recovery' a few times without much luck, it hung on the O2 flash screen.
I then got frustrated and was pushing the power button a few times, it vibrated and came back to life, complaining of a low battery.
Its charging now, running as a phone - Ill put the Sim Card in later. The only thing is why it seems to go to the HBOOT menu, even if not prompted at the start ...
Perhaps a reflash is still worth looking at, wanted to get 2.2 on anyways.
Edit - I suspect the vol down button is screwed, hence why it goes to boot screen at start and also it doesnt work when the phone is now on. Hopefully it will be fixed as the phone dries out - perhaps Ill venture opening up the phone to sort it.

Unfortunately I had a similar mishap while on vacation, I was carrying my phone while crossing a stream and slipped and fell down, phone got wet...
After a few days phone would power up and "work" but I noticed a few things that I could not fix:
1) Phone runs very hot - always close to 40 degrees celcius where normal phone is around 30.
2) battery will not last for more the 6 to 8 hours with almost no use. High usage / low usage makes no difference anymore.
3) If turned off battery still dies in about 6 to 8 hours.
4) The worst thing for me was the phone thought the headphone was always plugged in even when it wasn't so it was impossible to get sound out of the normal speakers making the phone unusable as a phone without a headset.
It seems if your Desire has the water sensors red under the battery your warranty is void from what I read on the forum and around the net - HTC will not fix or they will charge you the same price as a new one to fix it.
So I decided to buy a new Desire and now use the old one to test custom roms before putting them onto the other phone. I was afraid to Root before but being I had a toy phone I had nothing to lose anymore and now I am addicted
And as a bonus the Headphone / sound issue disappeared when I applied a new Radio and custom rom so that even works now. Only remaining issue is the poor battery life (replacing battery does not fix the issue).
Just thought I would share my story, I hope you have better luck then me...

Thanks for the info. I can see a red 'tag' inside the phone but on the battery itself there is a white sticker, is it either of these?
Ive gone ahead and bought a card reader and also a spare card - hopefully I can extract some value from it.

Both of those are water detectors.
Sounds like your phone has become water damaged but the battery didn't.
Your phone will now not have a warranty as a result and unless you have some sort of insurance that covers water damage (most don't) then there is nothing you can do.

yeah its what I thought, the water obviously got onto the phones tag but not the battery. Your lucky as usually when the battery tag goes the battery stops working.
Phones are often programmed these days to stop working when water is detected even when the phone is actually fine (easy way to get more money I guess). So I would be quite happy its still working if I was you

I need to figure out if its the software thats screwed or if its the volume buttons. They partially worked earlier, now nothing, back to boot screen.
Going to try and create a gold card to allow me to upgrade HBOOT and take it from there.
This is one of the first phones, so should be AMOLED screen, less risk for HBOOT upgrade?

easiest and best way to sort it out would be between the two options:
-buy insurance online, wait a few weeks then claim
- try and fix it, then fail miserably and wish you just bought insurance

Dont sound like good options - ....
Dont want to curse it but its running again, down volume also working.
Ive got some of the updates on a gold card, got an error with it, not sure why but less tempted to fiddle if the phone works as normal.

I got the same problem about a week ago when i cycled and it started raining really hard. so my desire got half drowned because i didn't have a rain jacket.
At first it appear as if my phone would work normally again, because the power buttons didn't work when i wanted..
However, a week later, it feels as if nothing has happened. so keep on praying ;p

Sounds to me you really should let it dry even longer because of the fact its seems to be still coming back to life. Take off the cover, battery, sim and sd card, stick it in a rice bowl or hang it in your pc fan airflow for 1~2 more days.

Solution for "camera black screen", "no charging LED" and "dead earphone"

Solution for "camera black screen", "no charging LED" and "dead earphone"
Hi!
My phone got several problems during the last day without any reason.
- camera shows black screen and crashes
- headphone jack does not work
- earphone dead
- no charging
I've done research via google and found several "solutions"
- change sd-card: not the solution
- wipe cache and dalvik: not the solution
- re-assembling the camera unit: not the solution
The last one i've tried fixed my problem: One of the flat connectors on the motherboard was detached.
After plug it in again, the phone works fine again.
It was not my solution, but i thought it might be helpful to poste that again
Check out this topics and the posts from "abenia":
http://www.htcdesireforum.com/htc-desire-troubleshooting/camera-doesent-work/
In my case, the reason was the connection shown here(black part to mainboard, connectors not viewable on the pic): http://tjworld.net/attachment/blog/htc-desire-tear-down/DSC00156-small.JPG

Hi Sui77,
i had a look at your second link, with the back of the phone opened up. Could you please be a bit more specific of the area where the connector is (the one i have to re-attach). maybe a red circle on the picture
Many thanks

Hi!
You might laugh, but i have had to redo the fix THIS morning.
The connector popped out again without any reason, so first flash stopped working, then LED, then headset and finally cam.
Ok, i opened up the phone and fixed it.
Sadly i ave had no cam beside me.
This time i put a bit tape on the connector, so it is blocked after reassemly.
I will do that again this evening and make a small "how to" and post it over here.
If not....kick me

Here we go:
Dismount the desire like shown here: http://www.formymobile.co.uk/desiredisassembly.php

Keep the upper board in place, just dismount the lower one.
Dismount the one screew in the left lower corner and detach the three connectors on the right side.
Now you are able to flip the lower board with the 2 attached foil cables.
The left connector is the reason!
Replug it, put some foam or tape on its back and attach it with tape to the surrounding area.
The reassemble the device.
It's all easy and may take you 10min

Hi, I'm experiencing the same camera/camcorder/flashlight problem and would like to try this fix, but I'm a little unsure of what to do after dismounting the bottom board. I haven't tried it yet, but I get confused with flipping the lower board and what left connector I should be looking for. Is it straight forward once the board is flipped? Would either of you be able to explain this a little more, maybe with some pictures? Thanks.
EDIT: So I just decided to go for it and it was pretty straight forward. It was the black foil-wire(?not sure what you call it) connector under the microSD card slot.
heres a picture looking down from the top:
you can see the gap between the connector on the right. just had to push it in, and presto! Camera, flash and led working again Thanks!

Hi biictorr,
congrats!
As I said, it is really easy.
I have had to do that twice, because the mentinoned connector got loose again.
Now I have applyed a bit of foam tape on the connector so it will be kept in place by the pressure of the housing.
Just bought a second Desire for $50 with the same failure for business use - took me 16 minutes to repair it :angel:

a lil help ^^
Your guide helped me alot, i took a photo actually of the back of the motherboard, i was wonering if you would add it to the post to help others

@itsJaeger
Thanks
I was glad to be able to add help to this forum once

Ty OP, have same problem just did what u said and its working like a charm. Ty one more time u save me money and time. Respect..

THX.
It's a pleasure to help

I repaired my desire as well!
Hi, another Desire user in here. This was the third time I had this problem but my phone was not covered by the warranty, so I was afraid of having to pay 50-60 euro, and I even was considering getting a new phone (Desire X had been offered to me by my carrier for €99) and then, what do you know! The solution was so simple! I checked that connector and the camera works back, the LED does too, everything works! Sui77, you saved me at least €50! You're awesome!

Hi camilou,
glad to hear that.
I'm running 2 old-school desires right now and bought two defective ones for my friends.
In my opinion there is no better phone for <50€
No reason to be angry in case of a stolen'/lost/broken high priced phone
I applied a saphire camera glass (amazon) and a polarcell battery (ebay) and everything is fine.
Recommended is the spazedog ICS ROM.

Ahhhh, thank you guys for this amazing guide. By magic my camera and torch works again

Hi.
Awesome, and thanks.
My issues were: Camera black screen, headphone jack, flash and battery recharge light not working. ** Also every time I set up the portable wi-fi hotspot, my phone would reboot.
I have never torn down a phone and found it easy and effectuated the fix.
Superb advice.
Reconnected connector ok.
ps Note to forum guys - this forum could be easier to use pls.

You're welcome

[Q] Wierd touch screen issue! (Nexus 7 2013)

Hello Guys,
I'm experiencing issue with touch screen on my N7 (2013) 32gb, Build number: JSS15R , Unrooted
When I put my N7 on the pillow, or sofa (Not wood or metal surface) , the touch screen NOT responding in some area on screen (on the picture below), otherwise, when I hold my N7 in both hands or just one hand it seems to work just fine!
Do you have this issue or only me ?
Note: I used Multi-Touch test app (by TPYXA software) also for this test, and I did factory reset with no any apps install (only Multi-touch app)

Same here. Thought my Nexus 7 was fine for a couple weeks. I have no clue what could cause this but I've tested it a lot and it is definitely fine in my hands or on a hard surface and always really bad on a soft fabric surface. It makes no sense, maybe a hard case on the back would help? Has anyone with this problem tried that, are you using it with or without a case?

will this be caused by statics on certain fabric? (really wild guess)

I will tell you what I think. I think it has to do with the wireless charging coils in the back of the tablet.
I am using a slimline Moko case. I tried it out of the case and it still did same on couch and pillow. On solid surface works great.Is there anyone out there that has taken the Nexus 7 apart. Unplug the wireless charging see if it fixes the screen issues.

This problem is also known as the grounding issue, although some say that's not an accurate description. Regardless, I had this issue and this thread fixed it. http://forum.xda-developers.com/showthread.php?t=2428133
Take a look and see if one of the files will fix your problem.

Wow, just tried it and seems like you right.
Screen going nuts when placed on my bed.
When i touching it with all ten fingers, screen automatically turns off and on, endlessly sometimes.
Seems like thats a hardware problem, i dont think any app able to wake up the screen.
Just made a video. Sorry for quality, my dorm roommate havent back yet, so i were filming alone with power of my ankle.

Google or asus or both should begin talking about this and what is the answer/solution they are going to give us. Mine is going to asus tomorrow, let's see what thy do. I know they have change screen, front and gps to another user, and did not even talk about gps problems at all, so they may know something.

Wireless charging coils. Its causing a magnetic field on the back of the tablet. causing something like a grounding issue but really not.
If you take your USB cable and plug it in to your Nexus 7 and run the cord around the screen it will go nuts. It should not do that. Same with head phone plugged in to Nexus 7 and the head phone wire touches the screen it causes issues. There is a shielding problem. or its the wireless charging coils needing taken out.
Electromagnetic Interference
Large power lines, electric motors, kitchen appliances, and other devices may directly interfere with a display picture. Many devices are not properly shielded and their electromagnetic fields can cause disruption. Most modern display devices have sufficient shielding to prevent interference, but damage to the shielding may allow for signals to penetrate. Older displays and economy brands may have minimal shielding, leaving these devices vulnerable. Cables and audio/video equipment are also vulnerable to electromagnetic interference.

@ lespaulman67
I agree with you :good:.
For me , when I plug my headphone into my N7 the problem with touch screen disappear even if I put it on Fabric ground.
Also, I have Galaxy Note II with QI wireless charging (QI wireless charger with the coil purchased from ebay 6 months ago), until now I don't have any issue with touch screen or charging itself.
Yes, I think the wireless coil caused touch issue.
Thank you all for the information , hope Google and Asus fix this very soon

Here is a logcat for touchscreen fail and sudden screen off/on turning.
Not sure if i did it right though
Note that NFC turning on/off by itself as well.

I have a couple of other tablets that I do amateur Dev work on, so I decided I can do without the nexus for a while and send it in for "repair" to see what happens. I'm curious to find out if they will change out any hardware or just flash a different firmware version and then send it back. I've tried every stock version if firmware with no luck, it seems to work fine for a couple if hour up to a day and the goes back to sucking. I'll report back in this thread when it gets mailed back and let everyone know what turn around time is like and if it actually helps. I have mentioned the ASUS customer service rep on live chat was excellent and its really easy to RMA it back.

I got my tablet back from he service center. It was a pain, they shipped it to the wrong address and then fedex delivered it to a neighbor, had to retrieve it and re-deliver it. Turnaround time at the service center was only one day but shipping in both directions was about a week total.
Even though I requested it, there was no notes on what they did so I contacted customer service. They looked up the notes and told me they had to open the tablet to re-calibrate the touchscreen and also loaded a "newer driver" to fix the issue. They also said it was safe to update the firmware if a new version is released.
So far the tablet is fine but I'll report back after using it for longer to see if the issue really is fixed. If they had to open the tablet, that sounds like people with this particular issue do have to send it in for repair because no firmware update can fix it.

Could you do me a favor?
assuming you are rooted, reboot your tablet
then type
su
dmesg | grep "ektf3k" | grep "firmware"
PM or post the output.

What do you need from the output? That command doesn't work together but I can grep them separately. I'm not nearly set-up enough to copy/paste the dmesg, so I'll have to type it out for now. Relevant parts, let me know if you need more:
grep for firmware:
firmware version: 0xa042
firmware id: 0x3029
grep for ektf3k:
x resolution: 0x007e
y resolution: 0x00d2
boot code id: 0x6047
Max X=2239, Max Y=1343
Don't know if you need the rest but I'm guessing not.

Mine got back from asus one week ago, they replaced screen, front and gps. Nothing was fixed, multitouch is still going mad, single touch is a bit improve, as before it works nearly well grounded but over a table or a sofa it works worst.
One friend got it back for a second time, the first time they did the same they have done to mine, now they changed main bd-2g, rear camera, screen, front and gps, 24hrs later he is reporting me that problems are back. Do you know what main bd -2g is? Motherboard?
Where did you type those commands?

As for the touch issues, mines obviously still got the multi-touch thing going on when you get several close fingers together. In my opinion that really has nothing to do with the Nexus 7. I've owned 8 tablets, not including the this Nexus and they all do the same thing if you put a bunch of fingers on the screen and then group them in close together. I'm pretty sure if you were to go to a Best Buy or something and play with all their tablets you would be able to reproduce the same thing on every single one.
The whole "only works when I'm holding it" thing was new to me though. It literally didn't work on any surface or even suspended on a stand. I've been playing around with it more since I got it back and putting it on various things, so far it works on every hard and soft surface, it also works whiles charging via USB and wireless charging. Another thing to note is that it came back with JSS15Q loaded. I haven't updated and don't plan on doing that for a while, even though the customer service people "guaranteed" me that it would be fine.
No clue about the bd-2g though.

Ok, you didn't get any "newer" touchscreen firmware. This is the standard one that came with JSS15Q/R.
So it is possible you have a screen that now behaves best with the latest touchscreen firmware.

screen flicker, screen freezes, and random restarts

I have an Tab S 8.4 LTE. Since upgrading to stock android 5.0.1 (from Sammobile), I have been getting screen flickering, screen freezes, and also random shutdown/restarts. None of that happened on 4.4.2, which the device came with. I've tried the following to correct the problems, with no luck: reinstall 5.0.1, cache wipe from recovery, factory data reset. Is my problem common? Is there a solution? Should I go back to 4.4.2?

A lot of problems you have mentioned is supposedly caused by an faulty/loose battery connector on the 8.4" , a lot of people say it started after upgrading to lollipop which is still not confirmed.
You can try the fix in the link below, but if it is a faulty battery connector a repair is your only real remedy to you problem.
This problem is quite common, have search you might find a more help.

This is a common problem of Samsung tablet, battery connector is prone to crack: flickering screen, random shutdown/restart, quick discharge, battery capacity fluctuation.
If you look at Galaxy Note Pro 12.2 threats, flickering problem is the same as this model. However, the fix is simple: re solder the battery connector. Go to a repair shop or anyone knows how to re work for assistance , the work takes only under 5 minutes. No need to remove the main board, just disconnect battery cable and do the re work of battery connector's solder joints.
This battery connector is not exactly but similar to yours:

In fact, it did start after the upgrade to Lollipop, so I want to say that, for me, that is confirmed. It never happened prior to that. Nevertheless, it could be a pre-Lollipop problem. Since the unit is still in warranty, I will try to explain the problem to Samsung here. They are usually pretty good about it when I get the chance to talk with a repair tech.

Try this fix in the thread below, it worked foe an Tab S owner the other day with screen flickering.

Thanks. I'll give that a try. It is worth noting that since I put 5.0.1 on my S4, it's been running smoothly.

Be aware that some depot techs are lack of technical skills to troubleshoot correctly, this one is a typical one.
When replacing new screen and motherboard, this guy virtually gave you a new tablet.

Repaired motherboard But I don't know what exactly they did

Well, I followed the instructions to force GPU screen renderiing and for about a day, it seemed to fix the flicker/restart problem. Then, boom, it came back. So it must be a hardware issue. Off to Samsung I go.

I wonder how hot the cpu gets when the screen starts to flicker, you can download free cpu temp apps from Google Store
John.

I took the tab s to Samsung and they found it was a battery problem. They replaced the battery and all seems well after a week. Now my question is, if I use my S4 charger, which has a little lower output than the tab's charger, will that cause any problem to the battery, beyond slower charging?

Slower charging as you said will most likely problem, use the free app below to check you charging rate, look at the average ma, and press refresh a few time, on the pro version you do not have to press refresh.

I wonder what did you do to fix the problem ?

Soldering worked.
I had the screen flickering problem and also random reboots on Galaxy Tab Pro 12.2 (SM-T900) and figured out that it is probably to do with the battery connector based on this post and an other post. When I opened the back cover and touched the battery connector, it just came out from its position. Samsung did a very poor job in designing this very important component which is the lifeline of the device.
However, following your advice, I first hesitated to solder it myself. I called up a repair guy and explained him that I need soldering the battery connector and he prompted $65 as the cost for it. So I decided to give a shot myself. I tried my hand at it and was able to get it done.
IMPORTANT: The connector ends are very very small and so you would need a soldering iron having a pointed tip. All you would need is to clean the battery connector ends with a hair brush and apply a very thin coating of soldering flux and have the solder lead on the pointed tip. The points on the circuit board are very close to couple of IC's and so be very careful not to touch them at all. Also, the plastic used in the battery connector component is not a good quality plastic and so be very careful in handling it.
Once the battery connector is soldered, I haven't seen any flickering so far and random reboots are gone. So far so good. I shall update this post if I see any deviation or any other update relevant with this issue.
Thank you @Beut for your post and providing insight about the problem.

Don't forget that a loose white battery connector also a factor of flickering, usually when disconnected it many times, this white connector may not make good contact with pins of black battery connector. I had one that black battery connector already resoldered but it still flickered at 70% batttery. I did a simple fix by pushing the opening tip closer. Many good batteries were wasted because most users don't know this simple trick, just disconnect and connect battery may fix auto reboot problem and don't know why.
This is what it looks like when a cable removed from the connector:
This is a bad contact, pin sits in the middle of opening of cable clip.
This is the adjustment to make the opening closer:
How to do it with a thin knife:

Then, this is a good contact
After the fix of male and female battery connectors ( black and white ), I guarantee that flickering, freeze, auto restart, auto shutdown problems will not return, unless you have a bad battery.

Hi @Beut,
I followed your post and fixed my tab by soldering the battery connector as you mentioned.
Do you happen to know what's the type of battery connector is it? I mean, if I want to buy that connector online, what should I be looking for?
Thanks.

I don't think you can find it online. Re solder is sufficient, no need to replace a new one.
But why you need a new connector ? Broken or damaged ? If you need one I may help you where to find it, but change this connector is not simple as re solder unless you know how and have right equipment like hot air gun, hot plate ...etc....

in a worst case scenario.

As of now, things are fine. The tablet is working fine even on longer duration of usage like playing videos on YouTube app continuously or video calls. The battery charge is lasting long besides there is no overheating like it happened before when the connector was loose. Thanks again.
However, when the connector got detached earlier, I observed that the plastic used to design that component is of pretty cheap quality and I doubted if it would stand even before I soldered. Anyways, I managed to solder that without breaking/damaging it. My fear is that the plastic base on which the (metal) connector components were placed in side-by-side fashion would disintegrate if when the plastic base gets damaged and that is my worry. I hope you understood my point.
Also, I would appreciate if you point me to any links that would explain a little more about these components.

Not charging after battery and port replace.

Update:
Try clearing USB Settings cache, wipe cache in recovery mode nothing work but what makes some improvement was following these steps (us.community.samsungcom/t5/Note8/Note-8-Died-Unresponsive/td-p/235388) that refers to charge stacking I did plug it and unplug it many times like 100 without holding the buttons, first like 20 tries I got the charging symbol with the yellow warning, after 50 it star flickering like if the cable had a lose contact it was at least showing the %, after like 75 it start showing as if it charges normally will go up 3% and then like 65% 66% 67% and the over and over again 65% 66% 67% and after the amount of time past so the battery discharge 1 % will keep doing the same now like 64% 65% 66% that's where I am at the moment.
Tonight I will heat it up to try replicating the first fix trying to melt the USB port connectors looking for a temporary fix so that I can make a backup if not will do the backup with 60% the battery I have left from the new battery. :fingers-crossed::fingers-crossed:

Hi everyone
Like a month ago, my A70 (one of my best phones so far in terms of value for money) stop charging.
At first, I thought it was the cable, the adapter, so I try different adapter, plugs, and cables until the point that my phone battery got discharged.
Confident that it was not the battery I bought the charging port part and start heating the phone to disassembly and replace the charging port while doing that I receive an important call and left for a meeting when I come back I was preparing my self to start the heat process again. Still, for no reason, I connected to try one more time before surgery, and voila, it starts charging.
My only explanation was that the heat must have melted the USB-C connector soldering and reconnect, so now it was working. I save the part, knowing that eventually, the problem will come back. And it did, one month later the same happen the phone stops charging, the battery got discharged, and then I open and replace the USB-C port part. Still, it didn't work I connect the cable get the thunder icon but not charging, so I say it must be the battery get a new battery today replace it and is not charging just showing the thunder icon for a few seconds then the screen goes black, but the phone is not charging.
I turn on the phone, and all is working perfect, the new battery came with 80% charge, so I know all is good. I even try safe mode to discard possibilities without success.
So I don't know what to do anymore? I don't even understand what can be or even to what the problem may be related to. I start thinking maybe I should buy a new port part because the new one was faulty?
I will appreciate any ideas or help.
Thanks, and have a good one!

i have the exact same problem, and we are not the only ones , i should've brought a k20 pro instead , can't believe it passed tests

So sad to know we are not the only ones, I guess that it the price to pay for buying a 2019 phone is like using the last update of windows we are the ones that will end up solving and reporting all the problems.
I will keep searching if I find something I will post it here please let me know if you find something. In the meantime, I will try to check the port part with magnifier to see if I get some clues and heat it up.
Thanks for your reply at least knowing I am not alone makes me feel a bit better or worst I dont know right now. :crying:

I start to believe it is the motherboard because if it was the charging port it would have worked just by changing the USB port board. I will try to put the original charging board in the oven to see if that works but it looks to me like a motherboard issue.

i found out it wasnt the usb port the problem since even the jack port stop workig when the issue occurs , dont go higher temps or components could start to melts.

i put mine on a metal cooking plate , also put something in the jack port like an old broken jack so the port keep his form even if heated too much.
tell me how is it going for you

As you can see, everybody is having this problem with this phone , because who hasn't used an after market charger/cord before.
After looking carefully about how people approached this, I am trying a method that I thought of on my own, to try and resolve the issue with the solder not contacting well enough for the phone to charge and possibly having some moisture in there as well.
This is a gentle method and I will report success if it prevails of course!
First take all protectors off the phone. Remove some/memory card. Place phone in a bag of rice so that the screen faces up with little rice on the surface. Aquire a magic bean bag from the local pharmacy, and heat it for 2min and 30 seconds. Place it on top of the phone /rice mixture. Set a timer for 12 minutes. Half way through heat the magic bag for another 1min. Place on too for the remainder of the 12min.
Once done. Keep phone stored in the rice for 2 days in a dry, cool room.
I will be reporting whether this is a simple back/fix for this terrible problem with these phones. Thanks !

Hi, I think I have the same issue you are describing.
My A70 refused to charge early January, would also no longer connect via ADB, but would connect via Mobile Odin.
I returned it, and they repaired it by changing the charging circuit. About 1 month later it happened again. But this time It started working again after about 1 day.
After complaining with my supplier, I got the response that is must be fine since it started charging again.
2 weeks ago, again. After it discharged it started charging again after about a day.
Now last week ago, 4th time, and no luck getting it to charge this time.
Again Mobile Odin sees the phone, and could even flash a new Rom.
But No joy charging.
Supplier accuses me of using aftermarket chargers, and that it's my fault. Does not want to extend warranty "again".

i dont have that problem i bought a wireless charger stand it fits on back hidden by case and it works great i wonder if your phone might charge that way
