I tried to Hard Reset my XDA IIi as one day right half of the screen was not responding to stylus. Now major problem as it is stuck on Align screen. Tried many times to hard reboot it but the same problem. Then I drained both batteries but the problem is there. Now I tried starting it up while pressing at the same time power button, action button and soft reset button. I am getting a dimmed screen which says Serial and at the bottom v1.01 nothingelse.
It synchronises with my PC and I can see the files are there but no idea as to why it will not start.
HELP, PLEASE!

Hang on... You put your device into bootloader mode, docked it and it synced ok and let you see your files? That doesn't sound right at all. When I put my Alpine into bootloader mode (when I was updating the Radio firmware once upon a time) once the phone was in bootloader mode (with the plain black Version 1.01 text on a blank screen) I couldn't sync my device or see any of the files held in RAM, so it sounds like there's really something wrong with your unit.
Have you tried (re)installing the same version of firmware, see if that does the job? It sounds like a deep-rooted software issue....
well, in bootloader mode, nothing to see of course. however, while stuck in the dead-loop of 'aligh screen', synchroniser still works and you can see everything inside! strange!!! beats me.
i tried before to detach the battery for a few hours so as to drain the backup battery. it didn't work for me. shall post again if it works for me if i leave it longer...
i reloaded 1.11.162 and 1.11.172 rom rom o2 and also the o2-stripped version with 1.04 radio, respectively, but none worked...
don't know if wm5 would help, but it's not available for IIi.
:evil:
Beginning to sound like you have a hardware fault then, if you've tried multiple different firmwares on fresh installs... Is the device still in warranty?

Wow, an insightful technical answer there then....and it's also a wrong one.
The failure of the digitiser overlay could be down to foreign objects stuck between the screen and the casing rim ( crumbs, solid dust etc etc), or warping / damage to the pressure sensitive overlay - look for scratches or 'puddle' areas on the screen that *look* like water between the sections - these are where the overlay is touching the digitiser glass and if this happens then the screen cannot calibrate as the pressure is not uniform. Heat can also warp the plastic overlay. Or, the connection between the overlay ribbon and screen ribbon could have become loose / broken.
In all instances if the digitiser is damaged you do NOT need an entire screen if the display is still working - you need to open the phone, remove the digitiser frame from the LCD assembly, source a new one and solder back on.
Digitisers are about £35 or so when they come up on ebay, I source mine from PDA's with broken LCD's - if you cannot get the exact type most of a similar size can be made to work - there are only 4 connections.
Now it may be difficult for the novice to do or hard to find a digitiser, but a 'new screen' is NOT the only option in this case just becuase *you* cannot do it or hadn't thought of it.
Richard.
Interesting that, because on my PDA I had that "water" effect in the centre of the screen (where I just bunged my Alpine in my pocket, and it got pushed against my thigh) - I put a screen cover on mine, and it seems to have solved the problem - it must be the even amount of surface tension applied across the top screen surface which has gradually pulled it away from the digitiser overlay layer, solving the problem.
I never had any accuracy problems anyway, and I succesfully realigned my screen a few times (just because I like tweaking) to see if it made a difference with the screen making contact with the digitiser overlay, and it always worked fine - but buying a £5 screen protector and seeing if that makes a difference could be a cheaper alternative to getting a new digitiser overlay.

actuallly..before i concluded that the screen was screwed..i have tried all the options that was mentioned by you..the digitiser overlay is not easily fixed or replaceable..in fact i have opened up the casing..clean it and also check the ribbon connectors in case it was loose..someone have tried to remove the digitiser and failed as the digitiser glass is extremely brittle and cracked whislt removing it..digitisers are also hard to come by and apparently they dont sell them separately now..only source is from a used lcd screen..the most convenient after all failed way was actually to replace the screen..

Nope, they're all over ebay from taiwan for about £25 plus postage but this is just the overlay with glass not the frame, and they *are* easy to fit - I've done a how to guide I'll post later. You don't need to remove the old one in one piece to fit the new one....
You said a new screen was 'the only remedy' - it isn't.

Interesting, interesting - I look forward to seeing that guide!
Hello,
I have the same problem described above, so my XDA2i is
stuck on the first screen align window and can't go over...
I wish to buy only the digitizer from an ebay user, but I have some questions:
-is the digitizer solded on the LCD?
-are the digitizer and the LCD two single parts?
-there's an howTo guide to disassemble the XDA2i?
thanks
Alessandro
Hello everyone!
I actually managed to change the digitizer of the LCD of XDA II. To answer the previous questions first:
Yes - the digitizer can be separated from LCD, although it is not easy. I used an old fashioned razor blade to do it, since these are very,very thin and do not put excessive pressure onto the digitizer screen during the pressure. The digitizer is made of very fragile glass panel and glued onto LCD with a double sided sellotape (at least looks like it, when removed..) Glue is very sticky and I had to take great care not to brake the old digitizer - took me 2h to remove it. In general braking the old one is not really a big deal as long as the LCD itself is not damaged by the sharp edges of the digitizer glass. Since the risk is there I figured I'd spend a bit more time on removal but at least be sure about a positive outcome of the project. There was a certain screen protector on my device, not installed by me since I acquired the gadget on e-bay. I took care of removing it from digitizer first and only then proceeded to remove the digitizer from LCD.
The digitizer has 4 connections soldered to the LCD. Opening the soldered contacts is simple, if one has any background in soldering at all. The difficult part is to remove the digitizer from LCD, really. Another difficult part seemed to be the soldering of the new one. There are XDA digitizers on the ebay, they do not have the same contact as the XDA manufactured ones so the really difficult part was figuring out how to create the contact. The old one had 4 contacts soldered in a small rectangle going clockwise from lowest left towards lowest right..
The solution does not look exactly elegant, but who cares how the gadget looks on the inside, as long as it works! The 4 contact block of the newly bought digitizer was divided into 4 separate hair-thin contacts and the two outermost contacts (those that come on the left lowest corner and right lowest corner of the small rectangle connection) were soldered first, then a bit of an isolation tape (a simple synthetic tape used for paper repairs et cetera) was applied over the freshly soldered contacts to prevent short circuiting. After that the two upper contacts were soldered and those covered with another piece of tape.
The new digitizer came with double sided tape as well, so after careful alignment it was easy to glue it in the place of the old one. The main thing during this process is to clean the LCD and digitizer from all dirt and fingerprints, I used alchol for that - vodka, to be exact. I reapplied the screen protector to the casing before putting the complete lcd+digitizer block into the device, but I suppose not all screen protectors can be reapplied that easily..
In the end the connection looked crazy but in principle all was as should be and after the reassembly the device was 100% alive again with the screen aligning properly! It was certainly a risky business but I bought the faulty XDA for 60GBP and the digitizer for 10GBP, 70GBP for a fully working XDA is a bargain I think, not to mention an excellent adrenaline rush during some moments of the project
I can provide the pictures of the finished connection if needed, it will require me to disassemble my Alpine again though..
I'd definitely find some photos useful - stick em up on flickr for us please, thanks
Excellent to hear that you got it all sorted, and got a bargain out of it. I don't think my wobbly soldering iron skills would be quite up to what you managed to achieve (usually I end up cauterising more skin than I do soldering wires whenever I have to solder as part of my Uni course, it's a bit of a love/hate relationship between me and soldering irons... I love to hate them).
OK, my apologies for the quality of pictures - smartphones are not too great in this respect and I do not have a digital camera. The big grainy one is my XDA - notice the medusa-like wire cluster next to the shiny manufacturers soldering The second picture shows the actual digitizer that was installed, here note the connector - that had to be divided by scalpel.
Excellent mate, thanks very much.
Congratulations on that, TommyGun! (Labi, ka ir Jc )
Indeed, without a good friend and solderer Johnc, who himself uses mere "phone" all this might have gone otherwise Hail to soldermasters!
Dissamble O2 XDA 2i
Hello all
I've got this problem with my old trust O2 XDA 2i now. I cannot get past the alignment screen at the momemt.
Looks like I would have to disassemble it now and replace the digitiser.. Would a clean up help or should I try to completely replace the digitiser?
Any guide/ steps to disassemble the XDA 2i would be greatly appreciated.
Thanks

A few month ago i got the Nexus S and was realy happy (still am) with it. A few days ago i noticed the top part of my display (actually the glass which is the front part of the phone) was raised a bit. Compared to the rim the display is raised by ~0.2-0.3mm. If i press the display if sticks back but the adhesive between the glass and the rim only holds for a few minutes and then the sceen comes off again.
I took the phone appart (yeah, warranty gone but i couldn't help it... ) and replaced the adhesive (actually there are 2 adhesive films - one part on the phone's rim and the other part on the glass) the adhesive seemed pretty strong - similar to the new one i've used. Now as strange as it sound the new adhesive didn't help a lot as the issue still remains. As i've seen i'm the only one having this issue, or am i not?!?!! Anyways i'd like to hear Your suggestions on fixing this.
One option would be to heat the glass with a hair dryer or heat gun to warm up the adhesive and then use a clamp or something to provide pressure and reattach both sides.
You might want to separate the display from the motherboard before you do this as I'm not sure how well the motherboard reacts to that amount of heat.
Note that the glass is actually adhered to the digitizer (sensor pad) which is adhered to the display frame. I'm not sure which adhesive is loose in your case but you want to make sure they all fit together in the end.
OK so I have a problem ... accidentally dropped this phone on the ground .. nothing serious like form 1m on wood floor and phone had small rubber back case, BUT now there is problem ... phone is responsive (android), touch screen works, but the picture is basically dead similar like from dead GPU on PCs.. I will provide you with a pic.
but the question is whats Wrong ? dead gpu or some wires ? and how expensive ?
May be its your display itself give it to Sony service center
I think your LCD has cracken itself, try to search is there are any cracks or something like that. However, you would need to change whole LCD with Digitzer as well, as far as LCD are not being seperating from digitizer. It would cost around ~70 - 80% of your phone price.
I posted this in the official Samsung forum but I get the feeling that nobody there has ever been inside a phone. Hopefully get better feedback here!
Going to provide a rundown of the phones history..
The screen started to go slightly green randomly about a year ago. But I noticed that turning the screen off and on again fixed it.
This issue became more and more frequent as time went on during a few months use.
Then it transitioned over to a permanent problem, with no amount of reboots or whatever to make a difference.
Then horizontal lines started to appear which would travel up and down the screen leaving the picture black in some parts.
Then I noticed another thing, turning the screens brightness down to about 20% removed the lines, and made the phone usable again (albeit still with a green tinge).
I thought that it must be a power issue rather than a screen issue, so changed the battery but sadly that didn't have any effect.
More months go by, and that 20% threshold got shorter and shorter until I had to keep it at around 10% brightness to get a full screen picture.
And now finally the phone seems to have died. It doesn't turn on anymore and there is no vibration so its definitely not just the screen being off.
FYI I couldn't see any signs of moisture and the moisture sticker hasn't tripped. But I still haven't ruled that out. I will examine further after getting some feedback..
I have of course tried all of the obvious like factory reset, clear cache partition and all that.
Before I open it up again I would like to know what people think?
Cheers!
Is the battery good? If the battery was really degraded though normally it wouldn't boot.
I wouldn't throw too much money at it especially when you can get a used N10+ for around $350 now. A substantial performance upgrade.

Hi thanks for your reply!
Yes I have swapped out the battery for a new one. The way it deteriorated felt like moisture corrosion but didn't see any signs of moisture inside when I looked. It could be deeper underneath the mainboard though as all I did was replace the battery so didn't see further than that.
Yeah I won't put much money into it, but I do have a decent understanding of electronics so I was hoping there would be a fix which I am able to do at home with basic tools to hand. Many things can be fixed with a reflow and individual pieces are cheaper to replace than say an entire mainboard. But I have no knowledge on this sort of problem so I'll wait to see if anyone else has and then open it up again and take pics of what I find.
Cheers!

Inspect the ribbon cable contacts for corrosion if you suspect moisture damage. Without a factory test jig finding say a solder fracture on a BGA chipset will be a lot harder. That's also another place corrosion from moisture damage can hide.
Generally with moisture corrosion damage will be evident on the buses and power supply section of the board.
If water damage is present the mobo is pretty much doomed because of the latent corrosion process. Water will also damage the AMOLED display pixels themselves if they're exposed.

Thanks for that. I suspect the screen escaped damage based on how it looked. All pixels were fine but those horizontal black lines would travel up and down so feels like maybe the controller or ribbon as you say because it felt like the screen was getting less and less power as time went by forcing me to keep lowering the brightness so that makes sense. Although it doesn't explain why it doesn't switch on anymore. Unless the phone is built not to switch on if the screen is disconnected?
cheers

Make sure the power button and contacts are good. Since AMOLED displays have an active matrix it could be that or the mobo.
Maybe someone recognizes those syptoms... thankfully I never experienced them.

Thanks for your attention and advice!
Sorry for the delay. I have had it back open and inspected every part closely for moisture damage. Couldn't see any signs but while I was there I changed the battery which sure enough fixed the power issue.
Strangely, the screen worked 10x better for about an hour after reassembly! Then it started to go back to the usual black lines engulfing most of it at the mid-range brightness level but not at low or high brightness which I find very odd. Last time I'm sure it did it at any brightness level over around 15-20%
Anyway better to just let you see for yourself. I have taken some videos and photos.
At this point I'm thinking it has to he solely the screen thats faulty as if it was any sort of power issue then it wouldn't behave this way..
This video was taken straight after reassembly.
Your browser is not able to display this video.
The other was taken a few days later.

You're welcome. Did you inspect the display ribbon cable contacts? Someone who repairs these could probably tell by that vid. Probably the display, but I would try to verify that before you throw money at it. For $350-450 you could get a used N10+, a huge upgrade but no 3.5mm jack. Samsung leaves more off every year, too bad the price doesn't go down too. schmucks.
My Galaxy M21 phone's AMOLED screen got damaged due to liquid penetrating a few days ago. I went to the repair shop and asked to replace the screen with LCD one.
After replacement, everything is working fine, except for the proximity sensor. It always reports far proximity even if I bring a surface completely covering the screen. During calls, the screen does not automatically turn off when bringing it to my ear.
I have asked the repair person, and he replied that the LCD screen does not have holes to accommodate the sensor properly, so it is blocking the sensor. But AFAIK if that's the case, the sensor should always report near value, not far.
Is there any solution for this or is this a known problem due to LCD screen replacement?
Welcome to XDA
Not really if the mobo doesn't support the alien hardware.
The firmware instruction set may able to be altered to get the new hardware to work as you want.
It been better to use the original display, but not doing so you opened a can of worms.
Water damage? Possibility of mobo damage as well particularly if the battery wasn't quickly disconnected. If it was salt or brine water it's already dead.

By water damage, I meant a small amount of water somehow got into the screen and darkened the screen slowly starting from one side (a common thing on AMOLED displays).
I can assure that the water didn't cause any problem other than the screen, because I regularly check the device stats & sensors. The proximity sensor is behaving like this after screen replacement.
Well the former of what I said then applies.
I'm surprised it will even function with an LCD.

Sorry to barge in friend,
Thats why I am very careful with 3rd party repair vendors, I have lost many phones to them, they REPLACE new hardware with old spare components,its a bad habit they have & thats why the OEMs have "Authorized Service Centers" exactly for this reason.
For Shamshung devices I suggest you go to Shamshung Authorized Service Center only as Shamshung parts are quite in demand because of good build quality.
Small Story: Few days ago I went to Shamsung Service Center to try to downgrade my M21 from A13 to A11 (my phone is within warranty) & as expected they told me "only upgradable not downgradable sir!". I knew they were lying because a friendly shamshung service center guy once told me they do everything there internally, they have repair softwares there. Anyway, so I took the phone to a 3rd party repair station and the owner named Salman told me he has downgraded so many Shamshung phones of newer models, all I have to do is leave the phone with him for about 10 hours & he will downgrade from A13 to A12.5 then to A12 then to A11.5 and finally to A11 so it will take time, NO! he was lying! He was charging me a biggish amount but not just that he needed 10 hours to fix the mess that would happen when he stole & replaced the new components with older ones. Thats why Authorized Service Centers only friend.
@OldNoobOne I already went to Samsung's authorized service centre, but they only can replace the screen with AMOLED.
I was desperately trying to avoid AMOLED screens this time because they get damaged easily and are more fragile than LCDs (that's my experience with them).
Don't know how much correct I am, but I have seen most AMOLED screens getting damaged completely due to the slightest of shock or due to a single drop of water somehow seeping into it. I have never seen this type of problem with LCD screens.
Looks like I should have bought a phone with an LCD screen in the first place.

Yes friend, not just that LCD screen phones tend to consume lesser battery too. Another way to avoid AMOLED issue is that is to use a plastic pouch during rains etc. (there is no problem in communications) or also use a flip-cover instead of normal plastic/rubber back covers only. Just use a good quality scratch/screen guard like 3D+ and LCD will look quite like AMOLED

All phones should be kept dry regardless of the IP rating. As you found out the AMOLED diodes used in displays are water soluble. The displays are sealed but if the seal is breached by water they will be destroyed in short order. Always use a good case to protect from impacts and high G loading induced damage when dropped. Wipe all water off immediately.
This N10+ in my has always been in a good case and unfortunately has been dropped onto concrete many times (zero visible damage). It has well over 8k hours on it. The display shows no sign of damage or degradation whatsoever. Don't use in direct sunlight and use manual brightness keeping the brightness at 50% preferably less it will get many years of service.

AMOLED displays use -less- battery, have infinite contrast (pure black) and the best color gamut. Higher and variable refresh rates are also possible, but these tend to use more power.
They are more expensive and have shorter, finite lifespans. Other than lifespan they are superior to backlight LCDs. That's assuming you protect the phone from drops and the design/QC was good when manufactured. Of course display quality can vary from manufacturer, model and individual displays. It could be you got a defective AMOLED display from the get go. Samsung's QC has been slipping in recent years it seems. A used N10+ in good condition might have been a better choice than a new midrange Samsung. It remains one of the best phones Samsung ever produced.
LCD displays are easier and cheaper to manufacture so you pay more for AMOLEDs.
If you prefer LCD displays by all means use them.
They are more rugged but not bulletproof by any means.
(Always protect LCDs from solvent exposure like isopropyl alcohol; they are open vented to the atmosphere and solvents can poison/destroy them.)
