I've got a g1 bought when they first came out that the screen stopped working on. I suspect that it's just the loose ribbon cable, since it's the initial run of the phone. The phone works, I can adb into it, there's just nothing on the screen. Unfortunately, I don't think I can send it in for repair, even tho it's inside the year warranty, cos I had changed the housing for a different color off ebay, which meant unscrewing the screws and breaking the void sticker. So, any recommendations of reputable-won't rip me off&won't break the phone while fixing it-repair services? I looked at the service manual, and really don't feel comfortable disassembling it myself when I am unsure what the problem is.
Edit-If you saw my earlier thread about flashing back to stock, in which I thought it was my fiance's brand new g1 that had died, we realized when we went to box the phone up that the IMEI on the dead phone didn't match the new box. I'd accidentally switched the phones when rooting his&updating the ROM on mine and not realized it. Moral of the story, never flash two phones at the same time!
Editx2-I'm in the DC metro area.
well since you've changed the shell it shouldn't be much harder to check out the cable. just remember in most cases if you have to force something to come apart you are probably are missing a step.
I've taken a few phones apart (bbs, motos, nokias, htcs) down to bare bones and their not that difficult as long as you follow the steps outlined in the service manual. If you are still uncomfortable messing with it and are near a big city most have well reviewed repair shops which offer warranties on their work. If they don't offer a warranty , I probably wouldn't mess with em.
Not sure anyone can recommend anywhere local (being that you didn't mention your local) but I'm sure a few other people can chip in on online sources(I've yet to use any so not comfortable with recommanding any, sry).
Good luck
I called up HTC a while ago, you can mail them your phone and they can do repairs. Just go to their website, it is under the support section. Unfortunately for T-Mobile replacements, one of the first things they ask is "Is the LCD screen working?"

I read on here that HTC charges likes $250 for repairing the screen tho, that's insane. I'm willing to pay a REASONABLE price to get it fixed by someone who knows what they're doing, but if the repair is gonna run me more than I paid for the phone and more than 50% the cost of a NEW phone, I'll suck it up and do it myself.
I can fix it for you, I have built a working G1 from two, one that was liquid damage and the other with a shattered lcd and digitizer. Where are you located, i am in alabama... now if you damaged the cable to the lcd, then it would require purchasing a new one. The lcd goes for $65 to $70 and the digitizer goes for about $80 on ebay.

I'm in DC, so mailing it to alabama is less than ideal. I'm exploring other options, thanks!
odds are you are gonna have to mail it off somewhere unless you do it yourself. i have had MANY phones and taken all of them apart to fix one thing or another, i never had any worries about my work and i never had a service manual. if something where to go whong with this phone i would be more confident in my ability to fix it since i can go find a service manual online
Well, my screen broke after 5 days, and the digitizer is completely unresponsive. It was barely a 2 foot drop! Here are a few pictures: one, two, three.
Anyways, with the sad story aside, I have looked into my repair options, and I have decided the most economical thing to do would be to order a replacement front assembly and do it myself. In another thread, I found this link. The drop resulted in a few scratches on the metallic frame, so I want to make sure that's also included in my replacement. Now, that link looks very promising, but I'm trying to save as much money as possible. I have browsed though Ebay, and found similar items that cost about $30-40 cheaper (after shipping) coming from China, but I'm a little skeptical about it. $100+ is expensive for a repair, so I want to make sure I'm getting quality parts. A couple examples are here and here. Are these parts directly from LG, and if so, how do they become available for sale through third parties? It's the quality of the parts that concern me the most. All said and done, I want the phone to look and feel as if it were brand new out of the box.
On another note, I'll be buying this as soon as it's available. I had one of those on my Nexus One back in the day, so I know my N4 will be well protected, even though it's going to effectively turn it into a cinder block. Such a shame that I gotta cover up such a beautiful device, but apparently it's too risky to leave the phone naked...
So basically, I just want some opinions about the cheaper Ebay options, or if anyone has a better recommendation. I've ruled out sending the phone to LG's third-party repair center due to the costs. I'm comfortable doing the repair myself, so I'm happy saving a few bucks in the process.
Why not send it it for a new device instead?

The Chinese make a dead on imitation of the N4. The only way to be sure you have a real N4 is to call Google and ask if your IMEI is legit. I'm guessing what you're looking at are screens for the copies. If you're worried, what's another few dollars for the real thing? I can see if they were half the price, but they aren't.
Also, why not get a bumper or a Ringke case? They still show of the phone.

I bought it from my carrier, and declined a $7/month replacement plan... I could get in touch with them, but I'm pretty sure they're just going to tell me it's my own fault and nothing they can do about it.

Mine is real. I didn't buy a Chinese fake. I was just wondering if the replacement front from those Ebay listings were real or not. I know it's hard to tell, but I want to make sure I'm getting original LG parts.

I was originally considering the official bumper, but I'm not sure if it will really be enough. I don't want to go through the same thing again.
I don't like the design of the Ringke case, either. I know Seidio's cases are great quality, but at the same time, they make the phone huge.

You misunderstood. I wasn't questioning whether or not your phone was real. I was telling you that the fakes are really good. Those are probably REALLY good fake screens. Understand?
Hi guys,
I have the same problem on my Nexus 4 which is now completely useless. Funny enough, the phone is still on but the touch screen doesn't work anymore... Let me tell you how annoying it is when the alarm rings at 7am on a Saturday morning and you can't turn it off...
Anyway, I hope I'm in the right topic and not posting something that has been answered already (I did a research...) but can you let me know if you managed to change your screen Bloodflame? If so, was it easy with the replacement kit that usually comes with the screen you buy. I don't want to go to a dodgy shop that will take me £20 for just a simple screen change... I'm sure I can do it myself.
I recently found one on eBay for £85, which is pretty much the best deal I saw so far (I can't send you a link as I'm a new member, sorry).
Thanks in advance for your help and apologies if the English isn't perfect (I'm not a native).

OK, I see what you mean. Just when you mentioned verifying my IMEI with Google made it sound like you thought mine was a fake. I understand the Chinese knockoff's could be hard to tell apart, and I understand that those replacement parts on Ebay may be fake. That's what I was skeptical about. They might be real, but maybe it's not worth the risk...
At first glance, the price appears similar, but the one from EtradeSupply comes to about $152 after shipping, whereas the Ebay ones are about $115 shipping included. I was just hoping I could save a little cash - that's all.

I only made this post last night, so no, I haven't fixed my phone yet. I haven't even placed the order for my replacement parts yet. But I can update this thread later on with my progress. Heck, I can even post pictures of the repair process and make note of any details pertaining to how easy/hard it is, a specific step that might be a little more difficult (ribbon cables come to mind), or anything like that.
FYI, you can disable your alarm from ADB as long as you have USB debugging enabled. It's a bit of a pain, but I was able to get a few things done using ADB. For instance, I was able to turn off mobile data, enable wifi, and make a full backup of my internal storage among a few other minor things, just in case.
Code:
adb shell
svc data disable
svc wifi enable
input touchscreen tap [x] [y]
input keyevent [#]
Google those commands for more details.

OK I see. No problem then, I ordered the screen yesterday and will also give updates when I'll change it. Hopefully, I'll receive it and change it before you and will therefore give you a few tips (if needed). I'm sure it's not that difficult but we'll probably need to be very cautious. There's probably a few videos showing how to do it. If I find a good one, I'll post the link here.

I didn't know this tip, thanks for the help! It finally went out of battery, so nothing to worry about anymore )
Just a general heads up:
I recently had the exact same problem, wanted to keep my nexus naked but it cracked after about a month. So I ordered a replacement last sunday of eBay for about $135 with shipping, it was not from China, from California. I received the screen yesterday, and successfully replaced it by my own, it was pretty simple and took me about an hour. I have never before disassembled a phone. The screen works fine and seems just as good as the one before. I could have sent it in to LG but they said they would remove all data from the phone for some security reason and I didn't want to do that. But if you have any more questions just ask me, I will be glad to help you.

Sounds great! Yeah, I've already briefly looked up a couple videos and guides (see this one on ifixit) and it doesn't looks terribly difficult. Also, I recall reading about someone who successfully replaced their screen, but ended up cracking the back glass in the process. Might be worthwhile to take a little extra care to make sure that doesn't happen to you. You've been warned

Yeah, I could understand why you'd want to leave the N4 naked - it's certainly a beautiful device! But on the other hand, stuff like this happens and it becomes an expensive mistake, as we've learned.
So just tell me, was there any one or two specific disassembly/assembly steps that were more difficult? If so, did you figure out any tricks to overcome the difficulty a bit? I understand working with small parts and flimsy ribbon cables can be a bit of a pain. I've taken a couple phones apart before, but never had too much difficulty as long as I was being careful and patient. I suppose the same is true here but I don't intend to take my N4 apart until I have my new screen and I'm ready to get to work. Payday is a week away, so it's just a waiting game for me at this point.
The most hard part I've encountered was taking the back cover away, that by it self took me about 15 minutes, if you looked at any videos you will know what I mean. Also when you take out the battery make sure to use a hairdryer to loosen up the strong glue below it, also be very careful taking it out, I found out it bends a little its basically made out of strong tinfoil, but if you do bend it a little don't worry it will still work

$120 ain't too bad, hell the deductible for at&ts insurance is $125. I'll have to keep that in mind should the unthinkable happen.
Google could make everyone's life easier and just offer 2 year replacement plans for a flat cost. No you should never drop it, but we're all human, it's bound to happen at some point. Thing is I want a flat replacement plan like what you would get from a retail store on consumer electronics, not scam insurance. Whats irritating is if you buy a tablet, you can get a replacement plan from square trade, but since the nexus 4 has a radio, it's $10 a month, $99 deductible. Ridiculous!

I had the same problem, first i tried to send the phone to a tech guy to try to remove the digitizer but he couldnt make it, then i bought a screen assembly and installed it myself. I live in Argentina so finding the replacement was not easy. The problem came afterwards when the screen touch was a bit floppy, i tried a Pointer Location app and i discovered that now the screen can read up to 2 fingers and it works really bad (it used to read up to 5 fingers). Is it possible that it is one of the chinese imitations? I didnt know there were copied parts for the N4 up to now
The only visual difference i spotted is that the original screen had little integrated circuits in the screen forming tiny nearly-invisible squares inside the front glass, and the replacement one has no such things.
Question In summary:
Has anyone swapped their Verizon motherboard to a sprint model or vise versa and got it to work?
In detail:
Ok so, got my Verizon note 4 wet few weeks back. Didn't realize how wet it got and started it back up too soon, worked fine for about 5 min and then the screen shorted out. After completely drying it still boots, still freaks out from all the messages etc pooring in from it being off, was also able to access from my computer to pull off data.
I was able to locate a mint condition sprint version for a reasonable price, my theory is that I can simply swap my mobo from the old phone to the new sprint one and be good to go. I tore it apart last night and soaked it in rubbing alcohol to clean off any remaining deposits,I'm trying to source a sonic cleaner to do a better job if possible.
Any reason this won't work? Any possibility I could damage the good screen with a bad mobo from the Verizon? Anything else you can think of that I haven't addressed? I suppose I could sell the sprint version and fund an actual Verizon replacement from the sale but if this will work...
bump, looks like i might be the guinea pig...

Why not just get the Sprint phone, unlock it, and just use it on Verizon????
You'll be buying a mint condition phone anyway. Why tear it apart when you can use it on Verizon if unlocked?

I was under the impression that sprint and Verizon run different tech for their networks. If they don't, or if the phone has the hardware to use either, then yes, I'd much prefer to unlock it and go that route. If anyone can confirm that'd be great. I had done a bit of googling on that earlier but everything I found basically said they were not compatible.

Ok, I just researched it and found 2 things:
1) Verizon won't activate any device not bought from Verizon. (According to a forum)
2) Sprint and Verizon use different IMEI types, so one carrier's phone won't work on the other's network.
So I guess you can't actually just use the new phone.
This now brings up the question of how swapping the mobo will affect the IMEI. If using a Sprint mobo will make the phone now have a Sprint IMEI, then you won't be able to get the fixed phone to register on the Verizon network. And, Verizon may not register the device anyway.

Hi everyone! I have a bit of a dilemma.
I bought two AT&T S4's from a seller on eBay. One for my Mom, and one for me. Now, the listing says that the phones are guaranteed to have a clean ESN and IMEI, are activation ready, and all that good stuff! So I get the phones yesterday and check both IMEI numbers and they check out. I went a step further to see if I could get them unlocked, because hey, why not? No dice. One phone's service contract hasn't been completed, and the other phone's Next payment plan hasn't been paid off. So I'm sitting here like . . . . okay, so will they both eventually get blacklisted? I sent the seller an e-mail about it. I could care less about unlocking the phone, but I do care about having the IMEI blacklisted some day out of the blue and not being able to use the phone, but that's another story for another day.
If the seller gives me some push back and things don't work out, I was thinking about switching the motherboard's out. I know another i337 motherboard would work just fine, but what about an M919 motherboard. Are they interchangeable? Just wanted to know! Thanks

Looking at both of them, I don't see any differences that should prevent it from working. The only thing I'm aware of that prevents some mobo's from working is the frame on the screen and the screen's cable. The connection for the cable is in different places and the frames differ slightly so they don't fit other mobo's (learned that when i had to fix my screen) but the I337 and M919 screens appear to be the same. Beyond just fitting in there and connecting, dunno.

Hi everybody, i need help about replace the motherboard of my galaxy note 4. I will do it because i think that the eMMC of my device is completely messed, i've tried everything in modding but nothing help, the device it's barely usable, it keep rebooting and it lag, only if i use the app to keep the cpu awake it's usable. Plus it doesn't read the sim card anymore. All started when one day, totaly random, it do a factory reset by itself and i lost EVERYTHING in the phone. So i see that on aliexpress they sell motherboard for my n910f, if i buy and replace the one i have now, it should all work without any problem? thanks for any advice
ps: sorry for my bad english, i'm italian

I can confirm that once you get the eMMC read failure messages there isn't any coming back from it unless you either A) Replace the eMMC itself or B) Replace the Motherboard. Since trying to micro-solder an eMMC chip would be way to difficult for most people out there (myself included, I cant solder for s***) the motherboard replacement would be the way to go.
I did try all the "fixes" here on XDA I could find, but none worked. Flashing the full recovery software in Odin took AGES (15 + minutes, it never took me that long, plus then 20 minutes to even boot)
Finding the part is one thing, installing it is another. I have never tried replacing a phone motherboard but my main concern would be if the board is unlocked, or atleast knowing the carrier it was locked to in order to get a valid unlock code somewhere online.
I was told by a few repair shops locally that its totally possible to replace the motherboard but there was a risk the screen would also break (So a replacement may be needed there as well). Honestly it might have been that they just didn't have very good luck with taking these Note 4's apart without damage or they just were inexperienced. But in the end for me when my first Note 4 hit the eMMC error, I sold it for parts (sPen, Screen, battery ect) and bought another Note 4 second hand
Theres a ton a speculation about this chip issue, be it heat killing them, consistant flashing or just a bad batch of chips used and now failing over time.

thanks for the reply! ok so, i must have to buy the motherboard. I've find one interesting on aliexpress, 55$ and full unlocked (at least they said that), replace it isn't very hard cause you don't have to take the screen off, just the rear parts of the phone (i've already did it when i change the headphone jack), so Tomorrow i order it and when it arrive i will tell you if it works i hope so at least

Best of luck with it and hopefully the swap goes well. I probably could have tried finding parts but the 910W8 model is different I guess.
I have replaced a mainboard with one from aliexpress, which generally worked fine, but for done reason my gps didn't work. Not sure if that was a problem with the board or just some connector not during properly?
Regarding the emmc error, I've actually managed to revive the old board after it had been sorry of bricked by the previous owner in a failed flashing attempt by putting it in the fridge while flashing the firmware with Odin (on xda someone suggested this, they actually say to put it in the freezer for a while, but I don't have a freezer and putting it in the fridge and taking it out for flashing want enough). It still has the error, but seemed to run relatively ok with a wakelock app preventing the CPU from falling asleep.
Though I get your idea, it feels safer to have a fully working mainboard.
The only problem buying a motherboard is from other sources other than Samsung you not sure if the MBA are brand new. I would say go to Samsung and pay for a new MBA and they will write your original serial number and IMEI to the new MB and you get a warranty..
Just replaced a mainboard...
Bought more than a year ago a faulty Note 4 thinking it was one with a faulty screen as the blue LED and vibrator would come on while pushing the start button and the phone was recognized by my PC. Turned out to be a faulty MB and while trying to replace the MB I damaged the screen.
So I ended putting all on the shelf. Meanwhile bought a note4 for my wife and figured that the spare MB could serve her phone in case it would go bad...Then recently stumbled upon a faulty note 4 where the owner claimed it was one with a faulty MB. The asking price was ok so I ended up buying it and fitting the spare MB. I was lucky in a way that the previous owner already swapped the display so it came apart very easy. I did put all in place using the OEM tape ordered specially for the Note 4. It is a fact that this MB is manufactured in Feb 2015 so it could be well that in the near future it fails although when checking the chip with the app it tells me I have a sane ship...

Hi everybody, i need help about replace the motherboard of my galaxy note 4. I will do it because i think that the eMMC of my device is completely messed, i've tried everything in modding but nothing help, the device it's barely usable, it keep rebooting and it lag, only if i use the app to keep the cpu awake it's usable. Plus it doesn't read the sim card anymore. All started when one day, totaly random, it do a factory reset by itself and i lost EVERYTHING in the phone. So i see that on aliexpress they sell motherboard for my n910f, if i buy and replace the one i have now, it should all work without any problem? thanks for any advice
ps: sorry for my bad english, i'm italian

You should search for videos on replacing the MB in the Note 4; it seems to be fairly involved and you run the risk of causing additional damage to your phone.
Samsung in the US is replacing MBs for about $50 to $150. I got mine replaced (plus a bunch of other repairs) for $70 (which is about the same cost of a MB through AliExpress). Samsung paid the postage for me send my phone to Samsung Service in Plano, TX, they then diagnosed the problems and said they would fix it for $70 or they would return the phone without repairing it at no charge. My phone was over two years old and out of warranty. I had them repair the phone and it was returned in like new condition and it is still working great. The entire process took about 10 days.
You may want to contact Samsung Customer Service directly (in the US call 1-800-SAMSUNG) and see if they are willing to look at your phone and hopefully make any needed repairs.

Thanks for the info will try it, my note 4 will not even
finish booting anymore. It is alteady out of warranty hope they don't mind it is rooted.
There are plenty of video's on you tube on how to. Look at them, look at different video's to get as much info as needed. Don't mess around with you screen, just replace the mainboard and you will be ok! Mine still goes very strong, its GPS is working very well even indoors. I owed a few Note 4's and this is the first one where the GPS is usable. Putting both note's side by side...well one GPS gets a fix and the other one.......well is useless! Did the same with a Note 2 where I replaced a faulty mainboard and this thing has the fastest GPS I ever seen. This Note was due to be sold but I have decided to hang on to it a bit longer...
Hi I am Samsung Note 4 user I have a problem since yesterday it is not registering on 4G or Lte Network only 2G is working. I tried lot but could not fix this problem. I changed the setting LTE/WCDMA but still it is not registering. Can and body helps me to resolve this issue. even I format my phone also by the problem could not rectified. I visited Samsung Center they are saying there is problem in motherboard. for replacement it costs 280$ in India which is very huge.

$50 to $150 is a pretty big range considering whatever caused these issues is originally still on Samsung itself for cheaping out. I thought about going the AliExpress route but I've never bought from there before and their site isn't the easiest to navigate...seems every seller with reviews is selling used boards (questionable lifespan?) and the ones with no reviews appear to have brand new ones, but are these brand new with the same old issue, so we're buying boards with borrowed time or is there a chance they're ones that won't have this issue. One could only hope that the new ones via AliExpress AND the ones being installed through Samsung have been revised to not have this issue, but we may never know until it takes a dump in another 3-4 years like the original phones appear to last.
I bought my phone used via Craigslist, so I hope that isn't their justification for additional gouging.
Hi all,
Looks like this guy on YouTube was experiencing the EXACT same issue that we're all experiencing (random restarts, boot loops, bricked phone, etc.) as a result of motherboard. I'm thinking about ordering one of the N910T motherboards off Aliexpress and hope for the best. I can't even restart my phone anymore...and I know my phone batteries are fully charged.
Seems like it works...I'm just nervous about taking it apart!
Regards,
Jeff
HI
i had troubles with my Note 4 lately, blocking and restarting randomly,
baked the motherboard in an oven and it worked great again but only for a 1 whole day then it only shows blue notification light when trying to turn on,
tried the baking today again at a bit higher temperature 200c for 10 min,
and it is completely dead now,
i am looking to buy another 910F board but reading the feedback on aliexpress seems like they are all baked, people are not satisfied, it works for a very short time,
dont know what to do,
can i put some other version like 9100 dual, some other that has better chips(not heating so much) exynos instead snapdragon or something like that?
