[Q] trying to unBrick evo 4g after a short swim

evo 4g slid off my lap wall turning a corner and landed in my 1qt 3/4s full cup of water. it wasn't till my second twitter text that i finely figured out were the fancy lights were coming from. i pulled the phone had my fiance take the cover and battery out instantly.
when i got home we took the phone, with no battery and back and submerged it in rice. after three days the phone seamed dry except for a small amount of water trapped between the digitizer and the screen. after another two days in rice i tracked down the tools needed to disassemble my phone to let out the trapped water.
while letting out the trapped water i broke the ribbon cable for the digitizer and had to order a replacement. 5 days later i installed the new digitizer only to find that my phone would not boot past the white EVO 4g Sprint screen. (given normal time)
over the days and mostly after rooting my replacement Evo i managed to get the swimming one to boot into Hboot/fastboot. from there it froze before booting into recovery. so i flashed a new recovery. then after letting it boot for 15min i got into recovery were i flashed a new rom.
where i stand now.
the phone takes a 20+ to boot then once it does i cant unlock the phone or get any indication that the touch is working. additionally when i hit the power button and wait a solid minute it brings up the lock screen again, shows the lock screen then immediately goes black again.
im running out of things flash. any ideas.

The phone has hardware damage. Sry boss.

Hey,
Yeah unfortunately you probably fried the electronics and corrupt the data, water damage kills phones and if you dont dry it out in rice until its all done your probally going to fry your phone! so you should be lucky if your sd card still works after this!
But this is all hardware and you will need to get your phone replaced hopefully you have TEP!
I wish you the best of luck!

I will reinforce the above statements. If your SD card doesnt work then plug it into your computer, enter disk manager, and see if your system at least sees that the disk is present. If it does then you can run File Scavenger and save your files. If not....then toss it in the trash with your phone.

i don't think it is a hardware issue. i have examined the board and can find no evidence of a short. also the phone boots, it takes a while but it boots, Hboot and Recovery (now) are fully functional. if it was hardware seams i would have less than i have.
is there a way to get a hardware error log or report through fastboot or adb? I'm not going to replace any components but it would be nice to at least know for sure what the final nail is/was.
O the SD card never gave me an issue. have been using it in both my temp phone and the replacement evo mentioned in the original post.

Ok, this is what you do....unless you have a great knowledge of microcircuits and boards, water damage repair is not an exact science.
I own a repair shop and this is what I do and I have about a 70% success rate.
Take apart your whole phone again, go to the store (K-Mart, Walmart, Drug Store and get a bottle of atleast 92% Isopropyl Alcohol. Submerge only the logic board in the alcohol and let it sit 2-3 hours. Then while still in the container of alcohol take a soft bristle toothbrush and clean all the contacts.
Take the logic board out and let dry (Should only take about 30 mins, alcohol dries very fast)
Reassemble and try to boot!!!
Best of luck to you!!!

it worked

Very cool. In case I ever drop mine in some water I'll try this.

long term affects
the phone takes forever to boot. i'm talking 10 min at the minimum. i have installed several ROMs, upgraded the recovery, no matter what i do this phone takes 100 200 % longer to boot than any of my other evo 4gs running the same rom, kernel, and recovery.
any ideas?
it really slows down my testing.
I want to test ROMS and use as a remote for my XBMC setup.

Did this work?

YES IT DID.
I use it as a network remote and for games, so i haven't tested the cell phone aspects of the phone but i don't see why they wouldn't work.
the long boot time is only draw back i have found.

Need help retrieving files

My mom dropped her Note 3 in water a couple days ago. I've dried it, soaked it in 91% alcohol and dried it again, but the screen won't work(Doesn't respond to touch input or show an image). I can connect it to my laptop, but it won't be able to load all the files. It will show a couple files before it stops loading, the phone vibrates, and it attempts to reconnect with my laptop.
Seeing as it's almost impossible to retrieve the photos the "normal way," is there any alternative to accessing the memory?

Wow. What kind of water did she drop it in? Did you let it soak in the alcohol for at least 30 min.? I hope you didn't try to power it back up whole components were still damp.

No, I let it dry over night, soaked it for a couple minutes(I didn't have the time to watch it for 30 mins cause I had to leave for work) and then let it dry overnight again. I mean, I can hear the bootup song, the volume keys work, and she still gets notifications from her wechat or w/e. Maybe I'll soak it for 30 mins .-. Unless you advise against using excessive alcohol. .-.
Aside from soaking it for 30 minutes again, do you have any other suggestions as for my next course of action?

Did you completely disassemble the phone to ensure all areas dry out?
Did you try installing a custom recovery such as TWRP and then booting into TWRP and mounting the data partition?

It has a custom recovery. I just don't know exactly how to navigate to that option because the screen isn't functioning >.<
Aaand I didn't completely disassemble the phone. I got as deep at the motherboard(Which isn't very deep) because I didn't want to deal with the adhesive in the device.
PS- is it safe to re-soak the device in the alcohol a second time? Is it too late to fix it?

It's possible that there is still moisture inside the phone and is causing a short when powered on. Have a look at some teardown websites for the phone. Don't remove parts that have been attached with adhesive.
Once disassembled, place all of the items in a plastic bag with uncooked rice or desiccant and seal it for a couple of days. I would not soak the phone anymore.

Thanks! Just out of curiosity, what is the danger in submerging the parts in alcohol a second time?

Alcohol that is less than 100 percent will have a distilled water component so soaking the phone again may not help.

Fixing the G4 Bootloop.

I want to fix the G4 boot, I'm no professional at this, I've tried heating the CPU with a hair dryer, it works for few minutes, then it goes back to bootloop again. I've put my phone infront of hairdryer for 10 minutes, then placed a small paper in front of the CPU and inbetween the tin heatsink, the phone boots up, i put up my email information, and other info, then after few minutes(before going to homescreen) it goes to bootloop.
Now, I want to take it to a mechanic, I want to know which part should I remove and resolder it back? Should I remove the CPU and place it back and solder it again?

anyone? It's kind of an emergency here. @interlitpol

It's dead, Jim.
You'd need a reballing station, and the knowledge on how to work on it, in order to half-assedly temporarily fix it.
The only way to fix it is to remove the SoC and memory, insert new soldering spots and use the reballing station to solder it back. It's an expensive procedure (I believe you can buy 5 new G4's with the price of this procedure alone) and not really worth it.
If your phone's already resetted and there's no important info on it, just put it in a drawer and curse it from time to time.
I'd say to contact LG, but you've already opened it and messed with the hardware.
If there's something important on your phone that you wish to retrieve, put it in a ziplock bag and leave it overnight on a freezer. That might allow you to turn the phone on for around 20 minutes, which should be enough.

Fixing a dead LG G3 (D855) with a hair dryer

Hello people of the internet and most likely LG G3 users. Yesterday my LG G3 D855 died right when I was about to watch some good hentai. I’ve been having screen flickering for ages in the YouTube app and as of late the screen also started to fade to black from the corners, random reboots were also quite common. Android became unresponsive for a couple of seconds and then the screen when completely black in a split second. Tried a lot of things after that: removed the battery countless times, changed with an old battery, charged it for hours at the time (battery wouldn’t get hot so no charging), connected to my desktop. No Android, no TWRP, no bootloader, nothing could make my G3 do anything. I was convinced it became a paperweight. After that I proceeded to disassemble the phone. Disconnected all the ribbon cables of the cameras and the display etc and put them back in firmly. That did do anything. HOWEVER I remembered when I was wasting time reading toxic XDA comments and stuff that someone mentioned baking the device to restore connections between the motherboard and the SOC, or something like that. So I did some research and even though something as stupid as putting it in the oven actually seem to work for people. Mum wouldn’t let me put it in the oven so I made my own way of resurrecting my G3. This is what I did to get it back working:
I’M NOT RESPONSIBLE IN ANY WAY IF THIS GOES WRONG AFTER TRYING THIS. IT IS 100% YOUR CHOICE TO DO THIS OR NOT.
Requirements:
DISSEMBLING
LG G3
Screwdriver small enough to remove the G3 screws
Plastic prying tool (old credit card, solid thin plastic will do also)
Good light source
REVIVING PROCESS
Hair Dryer that can get a fair bit hot
The grill of an oven
Stopwatch
A floor that can withstand heat
A place that can be ventilated in case of toxic fumes (nothing happened for me)
Safety goggles (I didn’t have and so didn’t use)
Electrical fire extinguisher (I didn’t have and so didn’t use)
STEPS FOR MAKING AN UNDEAD PHONE:
1. Remove battery, SIM card, SD card.
2. Proceed to disassembling the phone to the state where you only have the motherboard. I used these guides:
https://www.ifixit.com/Teardown/LG+G3+D855+Teardown/42288
And
https://www.youtube.com/watch?v=sNymIdIXTyI
3. Place the oven grill on a surface that can withstand heat and then gently place your LG G3 motherboard on it.
4. The heating process:
1.
Turn on the hair dryer and start to focus the heat on the part of the motherboard that is facing towards you when you take it out. So not the part where you see the SOC. See image. Hold the hair dryer close to the motherboard (5 cm space or so) and do this for 10 minutes.
2.
Let it cool down for 5 minutes and turn it around.
3.
Proceed to heat the SOC for 15 minutes and let it cool down fully for a minimum of 15 minutes.
4.
But it back together, hope that luck is on you side and that it will turn on.
NOTE: First boot went all the way till android boot screen when it crashed with screen flicker. I removed the battery and waited a minute or two and tried it again and it has been working ever since yesterday night. This is probably not a long-term solution so I’d suggest just using this to get your data off you phone and moving on to another device as fast a possible.

EDIT: Like I said before use this method only if you find putting it in the oven is to risky. My phone has now stopped working. This really is a temporary fix for if you just want to backup you remaining data.

i have used G3 for last 3 years and its was still good phone in market ..ok to the point
i have 3 G3 and one i bought for experiments and i put in Oven and guess what it show some sparks and burn from botton pat of the board so dont ut in oven it can burn and ic on board .. heating through hair dyer is safe i think for noobs... thanks

Galaxy Note 10+ stuck in boot loop with FRP lock

Hi everyone,
I tried to find any existing similar issue on the web and here but nothing exactly. I'll start by explaining what happened to my phone:
My phone got water damaged and I quickly removed the back cover (which was cracked and through where the water found its way in) and tried to dry it. I didn't have tools to remove the battery because I was on vacation.
The next day the phone was powering on, but the operating system wasn't booting. It got stuck in the logo and sometimes after a long-time waiting was booting but stuck in "WELCOME" screen and no touchscreen working (the first touch but then it was freezing and rebooting ).
So, I decided to to a factory reset, where everything got messed up. I did FR and it looked like it was going to work though it was taking too long to get to the WELCOME screen. But then it was still freezing.
I tried to install stock firmware with Wondershare DrFone which basically uses Odin (and I did use Odin alone) but it couldn't get through I guess because of the FRP lock.
>>>ATTENTION: I know how to remove the FRP, but the phone never gets to the Google page where you get asked to put the email address and password"<<<
I don't have much experience so first I was afraid to try anything else as I didn't want to brick my phone. I don't know if by installing TWRP I would be able to remove the FRP lock WITHOUT GETTING TO HTE FRP LOCK PAGE?? . By the way, I couldn't find the dedicated TWRP for my model which is SM-N975W on Snapdragon, carrier unlocked in Canada.
It would be appreciated if someone could give some advice on this issue.
Thanks in advance

Do you understand that my phone CAN NOT do any of these actions? If it gets to the Welcome screen (after the factory reset) it freezes there.

The phone must be completely dry!!!
If not disconnect the battery. This should have been done immediately. The damage may be permanent at this point if still wet.
Anhydrous isopropyl alcohol can be used as a drying agent but use discretion not to get it in between the display and front glass! Flush well then remove as much of the alcohol as possible, quickly as it's hygroscopic. Low pressure air can be used but carefully; don't force the alcohol where you don't want it. It will leave water marks on the glass if it gets there.
Place on side in a warm/hot, dry room with a fan blowing on it for 2-3 or more days.

The phone had the water damage 3 weeks ago. and it did get very little water inside, but enough to screw up the system I guess.

After 3 weeks??? It stayed in rice few days, blowed warm air after for few hours, left in dry place after that. There's no way this phone is not dry. No way.

It was a huge mistake of yours to turn on the phone after such a short time after flooding. If there was a short circuit and damage to a component, no amount of drying for a million years can help.

I totally understand and I was aware of the possibility of the short circuit.
But I don't want just to assume that there's been any damage to the electronic components since what we're facing right now is the phone is booting but the FRP lock is not letting us to proceed.
So is there anything that you can help with regards to this?

Water is not good... and it doesn't take much.
It may or may not be permanently damage. If it's salt water it's already dead. Fresh water exposure may be salvageable but don't count on it.
The biggest threat is corrosion. The power circuits and V+ busses were are at highest risk as are the ribbon cable contacts. Water will nest in the pins and cause corrosion especially if they have voltage on them.
The BGA chipsets have their contacts underneath them and their undersides must be perfectly dry. That takes heat and time. Heat drives out moisture. Anhydrous Isopropyl alcohol absorbs water to help displace it. Alcohol evaporates faster than water.
Anything up to 120F is permissible.
A vacuum chamber with a lower than atmospheric pressure can also be used to speed drying.

This is not the effect of FRP blockage, but, for example, damage to the electronics.

FRP unlocking support violates XDA rules. Don't get XDA in trouble! There are resources on the internet or Samsung can do it.
You must first be sure the phone is completely dry or it will be a goner for sure. FRP is the least of your worries.

Even if the phone is fully dry after several weeks, components could be still damaged.

The rom may have been corrupted or it's still wet or it's dry and blown out.
More than likely it moisture under a BGA chipset or in the ribbon cable contacts.
There's a reason manufacturers won't warranty water damage. Salt water is particularly insidious.
I've successfully salvaged a Buds case that deep sixed into a full cup of coffee, cream and sugar of course. Ripped it apart within 2 minutes, flushed with RO water then anhydrous isopropyl alcohol.
Allowed to dry for a day in the sun. Drank coffee. Over 2.5 years latter it still charges normally.
