[Q] Attempted touch screen replacement, potentially bricked or salvageable?

UPDATE: Screen is back on, but no touch sensitivity. Probably hit a brick wall on this one.
Hello all... so I think I may have bitten off more than I could chew Someone stopped on my phone and cracked the screen. After doing some research online, I found the Universal Repairs site, and bought a replacement screen and the necessary tools. The instructions didn't look too bad. Got the package, opened it up and proceeded to do every step in the guide as cautiously and carefully as possible. Thought I was doing pretty well too, until I had the whole phone put back together and tired to fire it up...
I popped in the battery, held down power, and felt the small rumble. That was good, but all the phone proceeded to give me was a blank screen, and after about 30 seconds, the LED turns purple briefly and shuts off. Plugging the phone in doesn't yield any LED color at all. I am able to get a blue light when entering fastboot mode, so that's something... I am unlocked, and was running a fairly recent version of FXP/CM 9.1. Right now I am downloading the latest CM 9.1, and will attempt to flash the kernel to see if that breathes any life back into the phone, but I'm a little pessimistic at this point.
I searched the forums for any approximation of this particular issue, but came up empty handed. Does anyone know if there's any hope for recovery in this situation? What does the purple LED indicate in this case? If flashing the kernel doesn't help, what other options do I have? Is it possible to try and find a service center and have the phone repaired/replaced at this point? Thanks very much in advance for any helpful responses.

It looks like I'm going from bad to worse. I tried using the Sony PC Companion program. It seemed to recognize the phone at first, but now it won't go into fastboot mode or flash mode at all. No more purple LED, all I get now is blinking red. I've never been very good at quitting when I'm behind.
EDIT: Nevermind, that all appeared to be just a symptom of a low battery. After charging it up for a little while, I'm back to the purple LED, and being able to go to flash mode or fastboot mode. However, flashing a FXP ftf did not do me any good, so I'm back to square one. If flashing the kernel didn't do any good, I doubt using fastboot to flash the ROM again would make any difference. Please help if you can, thanks.

I ordered a screen from them. Install was really easy but there was no touch sensitivity. I've been arguing with the company for over a week about it. And there 800 number didn't work.
You may want to take it apart again and check your connections, mainly the ribbon cables.

Hi slayer. I thought there was no way that would do any good, with the amount of dismantling and reassembling I did throughout the night, but I gave it one more shot, and lo and behold, the screen fired up. Reflashed to the latest FXP and I'm up and running...
...but I'm in the same boat as you. No touch sensitivity. And looking around, it seems like that's a common problem with repairs universe screens. I made double sure that the ribbon going from the phone to the digitizer was in there as snug as possible. Seems like a defective chip on the daughter board, although I have no way of knowing, that's just my guess. Sucks cuz now I have my phone back, but I can't make or answer any calls...
Anyone got any bright ideas for this?

Well I finally got them to send me another replacement, same thing. I think I'm just going to have to order one from someone else. I was thinking I might have messed up the ribbon cable but after reading that I'm having my doubts. I have a funny feeling they are sending pieces of glass calling them digitizers.

Ordered another digitizer from a different vendor. I'll let you know how it goes.

[Q] Not yet another brick question from a noob (simple advice needed).

So I was talking to some fellow geeks in my C# class and decided to root my phone. This site was suggested as the best one to go to.
To my amazement the first thing I saw was a guide w/ software on the first page. I was pulling all nighter, and decided to do that for a break.
So after a half assed attempt at reading the instructions and warnings, I went ahead like a retard and flashed my phone w/ an international OS.
I can't get into download or recovery mode. Holding the buttons down will bring up the Samsung screen, sometimes with the background in the corners is blue too (weird). Same thing if it's plugged in. If the battery is removed it will attempt to power on (the red LED lights up) then powers up.
I've noticed that with thicker cables and using a wall unit instead of the PC the red LED will stay lit longer, giving me hope it can be recovered with a jig.
So from what i've read here, I screwed myself and it's all my fault. So I have two choices
A) Send it into Samsung.
B) Recover it myself with a USB jig. I would rather do this, but im not sure if it's even possible to recover.
C) Also I just got this phone through insurance and haven't sent the old one in yet. It's a Samsung s3 too, just with a cracked face. Anyway I could use the hardware from that?
Any guidance would be greatly appreciated.

A jig is worthless here. You could potentially swap the mobo from the cracked screen one but it won't be fun to say the least. So your best bet is sending it to Samsung. Rumor has it they'll fix and return free.

I would suspect that if you cannot get into download mode you are probably screwed after having flashed an international rom. I basically did the same thing with my first s3 except it wouldn't power on at all. I was lucky after an hour sprint couldn't tell that it had been bricked and gave me another one.

Do like a friend did once. Tell the insurance company, they sent you a defective phone..

So figuring what the hell, I cracked open the cases of both S3's. Swapping the MoBo was extremely easy, and it worked like a charm. Fired up immediately. There was some technical difficulty getting the phone recognized on Sprints network.
Will definitely pay closer attention in the future to directions

[Q] Completely Grey Screen

I was hoping to turn my wife's old epic 4g touch into a cheapcast. So I bought an mhl adapter from monoprice. She hasn't used her phone in a few months so it was completely dead, so I charged it up and booted the phone and the screen was acting really funky with grey lines and such. The problem just seemed to get worse and worse over a ten minute period, and now the screen is just grey with lines sometimes, and completely grey at other times, every once in a while I can see the screen barely through the lines.
Capacitive buttons seem to still work and I can tell the touch screen is still working as I can unlock the phone, but I can't see anything on the screen at all. I did have the MHL adapter hooked up for a few minutes to verify it worked, and it did but thats it.
I seen some other threads about the grey lines being a battery issue, but I have three batteries for the phone and the same issue with all three. Two are cheap batteries and one is the original samsung battery. And I couldn't find any threads about a completely grey screen with a working touch screen.
So is it dead? Would recovery possible fix this? If so how the heck do I get to download mode without being able to see the screen?
This phone is stock unrooted with whatever the latest firmware update from sprint was. Sorry I can't give you more details, it wasn't my phone so I haven't messed with it too much.

Maybe one of the ribbon cables came loose.

Yeah I may have to do a tear down. Just seems odd that it would slowly degrade that way. Oddly enough I tried the MHL adapter again and it will display the screen, but its pretty difficult to type on the screen that way. I would probably be golden if the phone was rooted. Then I could easily load some vnc software and be done, but alas Its not rooted...

Not sure if you know how or not. But put tge phone in download mode and use a one click version no data of the same stock version number. Now its rooted and you lost no data in the process. You can find your build version in the about phone section of your phone. So if you have fl24 look up the one click no data version

It is likely that the battery is shot. What happens with lith-ion batteries is when they lose all of their charge, the become unstable to completely useless. When the phone dies, the battery still has about 20% charge left. Over time that charge drops to levels making the use of it inadvisable. I suggest trying a new battery first. If that does not fix it, we can work from there. Order one and check the flex cables in the meantime. An unstable battery can cause undesirable behavior of the device to include screen issues.

I suppose thats a possibility. Unfortunately I've already done a factory reset on the phone so theres not much there anyway. I'm used to nexus phones that make it super easy to root and sideload via adb, so I'm just going to have to dig in and do some reading on this phone so I can put all the pieces together. Certainly I'll choose that option over doing a tear down. Teardown will be the last resort.

Hey Thanks GrayDiggy, Unfortunately my cheap cast project is starting to add up a tad. I was hoping with three separate batteries I could eliminate that as an issue. I'll see if i can source a new battery cheap.

[Q] Moto 360 Black Screen -Resolved-

So something quite unfortunate happened to me last night. I factory reset my watch since I installed a new rom on my Moto G, and ever since I did that, the screen is black. Nothing else. The power button isn't doing anything regardless of how long I hold it in or whatnot, and it's just not doing anything, it's a brick. It's not rooted or boot loader unlocked or anything either. When it place it on the charging dock though, the light at the bottom of the dock lights up so I know it's charging at least, but I just really don't know what happened to it. Do you guys think it's toast?
--Edit--
So I spoke to Motorola's live assistance, and if this issue arises for anyone else, hold the power button down for about 2-3 minutes and it should boot into the bootloader, from there you can either attempt a fastboot reboot command or a normal powerup.

I tried your solution. But nothing happened. I think i have the same problem. Mine won't show anything, but when i tried charging, the light on the dock light up. Do you have any other solution? Thanks

Hi @Raging_Ken ! We're at the same boat. Do you any friend that have same situation as ours?

@presario3839
You also got yours from the states? I only know one other people who use the moto 360 and he also got it from the US. I'll check with him tomorrow. Can you check how much will it cost to ask for a replacement in Malaysia? Going there on middle of May, if it's cheaper, i'd rather pay the replacement there. Hehehe

I know it took a few tries for it to do that but at the same rate if you've tried it a few times then that's quite odd, It's also quite a pain how there's just one button to do it with. Hopefully you get it fixed, I really don't have too much else advice sadly D:

I think there can be three reasons for the black screen.
1. The watch has hung and needs the 2-3 minute bottom press as posted by the OP.
2. You use Watchface or Watchface Pro like myself. It has occasionally crashed on me. After several taps, I eventually have the menu come up and can get to settings/reset. I then have the default Moto face and can reselect Watchface. Hope this bug is fixed soon.
3. Hardware failure. LCD displays have a single backlight and if it fails so does the display.
I hope it's either #1 or 2 that you are running into.

this happens to me whene android wear crashes on the watch. i was able to notice the force close notification before it went to a black screen and did not respond until the battery died. once the battery was dead i placed it back on the charger and eventually it turned on. this has only happened maybe three times since i bought the watch at launch.

I've tried #1 but failed to force restart the watch. #2 seems not applicable to me since I'm using Facer.

[Solved]
Hi,
I faced the same issue suddenly (black screen) since yesterday, i came across your thread today trying to find a solution, and tried every solution posted here (e.g. holding 2~3 min on power bottom) several times, but no success!!
I put the watch at charging dock and the charging LED in the dock is ON.... but the watch is just showing black screen ... until i thought it might be from the USB cable... so i change it with its original USB cable which comes with it in the box (while unaware; i used a cheap USB cable from the market 2 days ago while organising chargers/cables in electricity outlet, without realising that i changed the USB cables), and once i used the original USB cable... it's started to work/charge immediately.

Solved

I hold the power button for 3 minutes, however nothing happened.
Soon after holding i put it back on the charger and it restarted itself and everything was perfect.
hope this works for you.

Yeah. I'm having the same issue. The only thing that allows me to turn the watch back on is to put it on the charger. Been dealing with this for a few months.

after I changed rom I can not associate my bike away bluethoot.
the Debug:
cached bluetooth device for device not found
E / bluetoothDevice (3177) getBluetoothClass () COD is 526 084
E / bluetooth Event Manager Settings (13790) Got bonding been changed fo Mac-addres wareble, but device not added into cache.
someone has this problem?

I have the same thing! Really frustrating.
If I put it on the charger there is nothing. If I put it in a "funny" way the light on the duck is on and I can even see the battery sign shown but it disappeared after a few seconds.
I used different chargers and cables and outlets in my house and other places - same thing.
I even tried a friend's charger (original moto 360 charger) but nothing.
I did try the "holding" (3 min is a bit much, no?) - nothing happens. I do have a blister on my hand from doing that 5 times
Any other ideas?
I bought this watch because I was curious and now i can't be without it. I will buy another one if there is no resolution.

I have the same issue. I put the watch aside for a few days (still haven't exhausted the battery), and then put it on its original charger, a few minutes later, the display come back! Don't know why, and don't know whether it will happen again...

Mi 6 seemingly bricked after 3 mths, won't turn on/recovery boot, no water damage

I have a 3-month-old Xiaomi Mi 6 that was working perfectly until Friday. I took it off the charger at around 9am, and by midday it had switched itself off. Now it's basically bricked; no amount of charging or holding power/volume button combos can wake it up. It's not detected by my PC over USB and display/notification light stays off. I'm currently leaving it off the charger for a few days in the hope it's a hard software lockup that needs the battery to drain before it will reset and power on again, but I'm not hopeful. I haven't had any water-related incidents with the phone, about the wettest it's gotten is in my shorts pocket at the gym, but I don't sweat much so pretty confident it's not water damage. Anyone got any advice aside from sending it back to Xiaomi for repair?

I was reflashing my mi6 through the TWRP recovery and the process was stuck at 99%. I waited some amount of time and decided to "reboot" it. So I held down the power button and turned it off. Since then my phone doesn't react on the power button anymore. I have exactly the same symptoms like you described. In my case, it is my fault but I thought it should only update some files in the internal storage, nothing more. I'm puzzled how could it turn into the brick because of that. I expected that at least the screen would turn on.

Also, as far as I can tell, a charged phone can stay in the off state for months. I think you need to find a better way to drain its battery. You may try to connect an external HDD through OTG cable.

So, I was able to unbrick my phone. It was unlocked, so if yours is locked you probably need to disassemble it and put to the EDL mode with help of the tweezers. Try to connect your phone to the Windows PC. Windows 10 detects and installs Qualcomm HS-USB QDLoader 9008 driver automatically. After that, you need to download MIUI ROM Flashing Tool and a fastboot ROM for Mi6 from here h t t p : / / en.miui.com/a-234.html. Unpack ROM's archive to some directory, open the Flashing tool, click "Browse" button, navigate to that directory, then click "Update" and "Flash" buttons. It helped me.

Thank you very much for the extra information. In the end I decided to send it back to Xiaomi for repair, but I'll keep your tips in mind for next time in case it happens again. Honestly though, this is a pretty huge design flaw if the phone does need to be hard power-cycled every so often due to an OS crash. I've been very underwhelmed with MIUI too, so I may end up just selling the device once I get it back and switching to the most popular Lineage OS phone of the moment.

A riveting update for those on the edge of their seats, turns out this was a fault in the mainboard and they had to replace the part. Wowee, what a plot twist! Phone is back in working order now.

great to hear that you have your phone back, did it really took 1.5 months to get your phone back?

Regrettably so. It was a combination of factors: I live in Australia and bought the phone from a Hong Kong eBay seller (everything takes 3-4 weeks between asia/Australia unless you pay for express shipping), and they had to send it back to Xiaomi's repair centre there, and Xiaomi had it for a week or two, so it all took quite a while to get back. The joys of buying a phone on the grey market. This is the one area that Apple service shines.

I think defects are normal with these high tech smartphones. Quality control cant see the small issues that manifest themselves into mobile deaths over time.
You have just found other like minded people with the same problem here.
People without the issue are staying quiet haha.
Companies usually just build in these defects into their projections and swap out the device when needed.
I think most people who have warranty issues with Xioami are the ones like me who buy through third parties.
So you have to return the phone to seller. They then return it to their supplier who then passes it onto Xiaomi for warranty.
That's where the long wait times come from for international owners.
I had more issues with Sony and even with warranty directly with Sony my phone was returned bent from a warranty covered screen replacement.
They fix one problem and create another. At least with Xiaomi I'm seeing people get the phone repaired and that's the problem solved

Did you think about EDL Recovery ?
