Redmi note 4x replacement housing - Xiaomi Redmi Note 4 Questions & Answers

Discovered my back cover is bent after taking my phone case off. tried to bend it back but now there are gaps where the buttons are. Still works fine I am just looking for a replacement back cover.
Any recommendations? I've looked on aliexpress not sure which ones are good or not, and some comes with "fingreprint flex cable" and "Sim card holder" they look dodge as, not sure if its meant to be inside the cover or outside. . . . regardless do i need one with fingerprint flex cable? is this somehow attached to the external covers?
Covers i am looking at https://www.aliexpress.com/item/for-Xiaomi-Redmi-Note-4-Global-Battery-Back-Cover-Rear-Back-Door-Housing-Card-Tray-Holder/32905160801.html?spm=2114.search0104.3.10.3749fb1ar1oAVk&ws_ab_test=searchweb0_0,searchweb201602_4_10065_10068_10130_10547_319_317_10548_10696_453_10084_454_10083_10618_10307_537_536_10131_10132_10902_10133_10059_10884_10887_321_322_10103,searchweb201603_70,ppcSwitch_0&algo_expid=f3ba9a01-2a7e-4b0f-ae21-4f6e684df1cc-1&algo_pvid=f3ba9a01-2a7e-4b0f-ae21-4f6e684df1cc

Some help for a newbie... [broken screen]

First of I would like to say thanks to this forum.
I try not to post any problems that have already been answered and this forum was a big help in getting my xda unlocked.
However I had only had my phone in working condition for 2 weeks, enough time to start to like it, when it fell and cracked.
I ordered a new glass screen (no bleeding ink) and had it overnighted. I sucessfully swapped out the broken scree, but in the process I screwed up the phone. So here is whats going on with it, if anyone can help me out it would be awesome.
When taking it apart I accidently broke 2 of the connectors for the ribbon cables on the back of the pcb. Now the phone wont turn on. The screen comes up but its just white and I cant tell if the os is loading.
Sorry for the long winded post
Thanks for the help
Chris
Also if this cant be fixed whats my best option, selling it broken or parting it out? How much could i get?

Well, I guess it depends on how broken the connectors are, but this definitely doesn't sound good...
If you post a few close-up pictures, I'll tell you if there's any hope for fixing it.
Well..
One of those 3 connectors lead to the screen.
My wild guess would be that it's not porperly connected since it's borken.
In that case, I would have done one of two things:
1. Buy a connector through an electronics component vendor, then ,manually replace the broken one or have a electronics lab do it for me.
2. Solder the wires to the connector's base manually (or in a lab) to over-ride it. (I hope you understand what I mean).
At any case, my guess would be a broken connection somewhere in the connectors (one of the 3). This can probably be fixed that way or another.
BTW - I have a lot of dust between the glass and the screen. How do you remove the glass from the screen (it seems to be attached firmly somehow)??
To take the glass apart from the lcd, there are 4 metal tabs (2 at the top and 2 on the bottom) you can pry a thin flat-head screwdriver between the metal tabs (you will see what I am talking about, when you look closer). It will sound bad but its just the glue coming apart.
I tried to get the connectors but had no luck finding a match.
So I am going to part out the phone.
Ill be posting the ebay auctions for the lcd screen, the new glass piece, the motherboard, the battery/case and whatever misc accesories I have lying around.
Before I put all the parts on ebay, I figured I would give the people on here a crack at it. I will entertain all reasonable offers. Send me a PM.
Here is what I have for sale
Case in good condition w/ battery
Motherboard - in good condition just missing the two plastic pieces where the lcd connects.
Brand new glass touchscreen/digitizer
Lcd Screen
Also for sale the in-wall charger, the sync cradle with an extra 3 stylus (styli?).

[Q] HD2 - Cannot remove housing

Hi,
I recently purchased a HD2 on eBay. It was supposed to come immaculate but unfortunately there are dents on almost all corners. Rest if perfect.
I saw on eBay some chinese sellers selling new housing + battery covers for ~25 USD. So why not replacing the housing then? I decided to give it a try.
Well I have to say that it really did not work like in the videos I saw on youtube. I removed the 4 screws under the battery cover, gently pressed the back of the LCM outward but it really refused to pop out (no even half an inch). I discarded the pry tool (a very thine credit card actually) and even tried using a suction cup on the digitizer to pull it backwards but same problem. It's like the LCM/chassis was glued on the bezel. Phone has never been disassembled before (white sticker and void screw were still both there).
This is strange because in all the videos I saw the LCM/middle chassis was clearly not glued on the bezel. It immediately popped out a bit then you could start prying (and praying!). Ok I know that in those videos usually the phone has already been disassembled before so other attempts require less force to do it again for the recording.
My questions now to all the people who managed to do this. Did this require so much force? Is there a change and is HTC now glueing this part the LCM/middle chassis to the bezel? Any suggestion? Where is for you the best place to insert the pry tool when you start?
Thanks and regards,
Try flexing the plastic bezel above the earphone outwards a little while applying slight pressure to the sticker area on the back. There're two notches above which locks the frame to the pcb.
Hi,
Thanks for your help.
I will try that later.
I guess I might need to find a better pry tool.
BR.
Ok I managed to do it.
This required clearly some force on the pry tool (actually I used two plastic cards : a very thin and flexible one than a credit card). I started the operation above the earphone area.
Applying pressure on the sticker area was stresfull because the LCD immediately reacted to the pressure (hence a risk to break it or damage it). Best was to put two fingers on the sticker area to help the LCM module to pop out but with (almost) no pressure.
I had a doubt and now that I managed to remove the housing it's gone. The antennas (those white stuff you see in both top corners and at the bottom) are glued to the housing.
I prefer to spend a few more bucks to take a housing which has those antennas already in.
BR.
i had a similar frustrating experience to yours in trying to snap the back off the chassis on my hd2 which had a fingerprint on the *inside* of the camera cover glass which i needed to open it to get at.
it sure looks easy in that HTC disassembly video on youtube but the tech there is using a sort of plastic hooked tool for the job, which i didn't have, so i used my thumbnail instead in the same place (the upper left corner, looking at the phone from the front) and it took me a good 20 minutes of applying what seemed like unreasonable pressure to my touchscreen and nearly tearing my nail off to get it to pop out.
those snap-tabs the electronics manufacturers use to hold cases together -- even when they also have screws to do the job -- are one of my all-time pet hates. i usually end up breaking them off.
I will be doing the same thing soon. So the housing you removed has antennas glued to it ?. Thanks for that, I will try get new housing with antenna together if possible.
I replaced my screen a while back and can confirm the main body of the hd2 is glued to the sides of the chassis.
It does come out but with a lot of force but pry the glue lose around the whole chassis first by sliding a thin card right ot the bottom of the case and slowlyu move and pry it upwards with 2 cards one on the top and other on the right after you losend the glue. the top has the wifi adapter n that so be careful bottom has usb so mite break.
honestly i would say don't bother replacing it and just get a gel case or something to hide the damage. there's a high chance of messing the digitizer up and would just cause you more trouble of taking the whole phone apart bit by bit and trust me the components are tiny so easily breakable especially the ribbon cables they decided to use. my honest opinion don't

yep they are white thin bits glued to the top portion of the case. wifi on left and phone on right if i remember. its been quite a while though since i took my old hd2 apart
Now that I know how to do this I will be easier next time.
Yes antennas are glued in the housing so best is to buy a housing which has antennas already in.
Important note : the antenna which is at the bottom of the housing exists in two different versions : EU or US so check with the seller which one he sells.
BR.
Top left : Amphenol-BT&Wifi-090820
Top right : Amphenol-GPS-090820
Bottom : Amphenol-EU-090828
If T-Mobiles US you need Amphenol-US

i don't believe it's glued. as far as i can see the the case is held together with screws and plastic interlocking tabs. the trick is to get the latter to unclip.
No glue indeed just notches locking the LCM module to the bezel
Ok case closed
I got my new housing and the replacement went fine. For those who could be interrested I bought it on ebay from the seller forceviewer_uk in China. Everything went perfect so I can recommend this guy.

titan back covers and ebay questions

http://www.youtube.com/watch?v=x1x55gEKSiI&feature=youtu.be
The above clip is a video of my problem
So I have been on a 2 month odyssey with my uk, euro titan and its original back cover, although I had its original back cover painted white and works great, I have been trying to buy replacement back covers from ebay only to find that they do not securely fit, after a few tugs, pulling it out of my pocked or just letting it drop lightly say on my couch, the back cover and phone easily come apart.
I have purchased from sellers in china and even purchased from a supposed uk seller from ebay.co.uk who turned out to still be a seller in china, both covers do clasp into place with the phones screen/guts, but pop easily out with the slightest bump.
I currently am in contact with HTC America who are going to send me an oem back cover however it has been backordered for 2 weeks now.
although I love my painted white back cover, it has experienced wear and tear and i just long for things to be "normal" again. my question is has anyone heard of this problem with the titan and back covers that don't fit properly? besides buying a $70 oem back cover from htc uk accessories, does anyone have any tips or know anything that could help?
I also want to mention I had sent my phone to htc America to replace the screen, gps and the worn out "button presses" on the inside of the phone. and they did, they replaced each and every single thing including the inner plastic body lining where the volume button "presses" are and the plastic surrounding the sim card all replaced, I can only guess that if maybe I did not ask to replace this plastic that hooks itself to the back cover that maybe any grey market back cover would have fit securely?
and also want to mention yes my original back cover that is painted still fits and firmly grips the phone, when I look at all 3 back covers the 2 from china and my painted oem back cover, I can't tell a difference at all in their inner workings SIGH

Possible to fit i9300 motherboard into i9305 front assembly?

I have bought a new front assembly for my S3 i9300 on eBay. When it arrived I saw that it is a i9305 front. I have tried to connect it toghether and everything works.
The problem is that the assemby base has some holes in the wrong place for some of the chips on the board. Therefore the motherboard will not go down properly.
Is it possible to dremel out some pieces so the motherboard will fit better?
I know this a special solution and certainly not recommended, but is it possible?
Else I have to return this front and hope for my money back or a replacement front. Either way this will be a time consuming process...
Has anyone tried my little experiment above with success?
why ot return it since they advertised a and sold you b?

Because that would mean another 2-3 weeks without a working phone....
Dremel + Hammer + Araldite + Fingers Crossed is the alternative .
Yes it is possible, but requires modification.
I bought a secondhand i9300 cheaply because it said the screen was replaced and back cover did not fit properly anymore. I took it apart to try and fix it only to find out the screen has a big i9305 printed across the back.
I had to file down the ridges in the metal frame near the power switch and also had to shave a bit off the back plastic case to make it sit a bit lower so that the back cover was flush with the front.

Xperia X Ultra Screen not working due to slight crack

Hey guys.. I know this z ultra thread is almost dead and i might not get help, but i am gonna give it a try anyway.
So the story is.. last year i kept my xperia z ultra in my laptop bag and after half an hour when i checked the screen had a little line(crack) in the middle of the screen from one end to the other.
The phone turns on. I can see the display but it doesnt recognise my touches. and it randomly keeps on launching apps and touching screen here and there.
I would like to ask what exactly went wrong here.
some of my friends had this phone and their's were working even after cracked screens.
Can i replace the screen? and is it worth spending on this phone now?

I had the same thing happen to me over 2 years ago. I finally got around to fixing it, because I was weary of bad LCD screens and I wanted to do it on the cheap.
I bought one from AliExpress and can confirm it is an OEM LCD panel. Only $36. Arrived in 3 weeks and it works like it did before, minus the waterproofing of course. In fact, this seller is all about OEM, good place for other devices as well.
Here is the link (I can't post links right now so it needs to be copied): goo.gl/et1vd6
I'd say it's worth it. It makes for a good backup phone and mini tablet for when you don't want to bring a tablet.

WOW that is cheap! To bad its not available anymore..
If I buy a new phone and this is no longer my primary phone I might change the screen and frame!
My chassis is cracked in half both at the sim slot due to its being so thin there and at the ear plug.
And my usb port is is not working cause of pin 1 that came loose that I soldered once but it came loose again so I ordered a new connector to be replaced completely.
The pins has started to move around due to wear in the plastic inside the connector so when I connect a usb cable it will tweak the pin back and forth until it breaks loose of the solder point.
And my earplug needs to be replaced due to 3.5mm plug comes out to easy but thats easy.
I have a question. How did you remove the battery?
I probably need to flip the motherboard upside down for the usb port that requires the battery to come out first.
I tried to break the glue underneath but the battery started to deform and bend just slightly and I'm worried the battery might burst into flames.

Man, your Ultra has gone through a lot!
Dang, didn't think they'd go out of stock. Pretty much the only online seller I trusted, because they compare OEM displays with fakes.
As for the battery, I don't remember how I got it out. I took it apart over a year ago when I bought a non-OEM display, so the adhesive was already loose. If you're in a situation where the screen is not working, you could just heat up the front to take the screen off and heat the body where the battery is, that way you're not putting heat directly on the battery.
Just be careful about the connector, especially if it's still plugged in.

If it's Z Ultra we are talking about - you unscrew 4 screws on each corner and pry battery from the right side with a plastic tool. It has two adhesive strips on both left and right side.
Though you don't need to take the battery out if you want to replace the screen, the connectors are at the bottom and accesible with just the metal cover removal.
By the way the reason why touch stops working the moment your screen cracks is because the capacitive layer is integrated into the glass, and when it breaks the connection is severed and no longer working. It is a shame, and the glass on this particular phone is very fragile, I suggest putting a tempered glass protector on it, so far mine holds up fine with it.
If you don't want to go thru hassle of repairing it and looking for a new device: the Z5 or XZ premium I think are best options of the sony side as the XA Ultra gives midrange experience at best.
On the same screen size id give S8+ or Note 8 a shot, they look promising.

Thank you. I had trouble locating where the glue strips are so I kind of felt my way where there was something sticky but didn't make much progress.
I got one corner out but then I gave up.
Since a few years I use tempered glass back and front. They are a lifesaver! Not very cheap but worth every penny.
I'm not sure if I'm going to take my phone apart for the tenth time or so..its very fiddly to solder this tiny usb connector.
Atm i'm using the magnetic cable and a phone case so it stays in place but I'm working on a "workaround" with my old battery case with two 18awg cables soldered to the dock pins (cause I hit current limit with thinner awg) and ordered a dip to micro usb board to solder these cables onto.
So the case only contains a strait path from the usb port to the dock connector on the battery case.
The idea is If the port brakes I ware out the dip board instead of the internal usb port when charging.
Easy maintance and low cost of replacement parts. Ten dip boards for 1 usd vs 2 usd for three internal usb ports.
And I don't have to worry about the magnetic dock cable coming loose all the time.
I started to look for a new device a month ago. Its showing its age.
I'll continue writing in the other thread..so we don't go too off topic.
Fck
Sadly an extreme issue with Sony phones for many years. Along with the dreaded sudden death that effects so many models its more widespread then LG bootloop and Apple bendgate combined.... And somehow denied as a defect by Sony and unknown and disbelieve by many....
Both issues I think however are rectified since 2017 I believe though.... Finally
