Can't allign my screen.

Hey guys!
I'm experiencing a very strange and annoying issue with my BA, and I was wondering if I could get some input from you.
So, here goes:
The touchscreen (not LCD) in my unit was broken, and thus I decided to fix it. I purchased a new one off eBay a few weeks ago, and just yesteday I proceeded to install it. To my surprise, something seems to have gone wrong.
I power up the unit, make my way into "Allign screen", and then the last "cross" that I have to touch rarely clicks in. On the other hand, when it does get detected, it simply restarts the alligning process.
What I've tried so far:
- allign right after installation -> no luck
- hard reset (on WM2k5_v4_R2.1) -> no luck again
- opened up the unit again, repositioned the screen -> nothing
- upgraded to Logout_WM2K5_5.4.03_HN -> still nothing
Right now I'm out of ideas, and I was hoping somebody here has some. Do you think the new touchscreen might be flawed ? I'm already discussing this issue with the seller.
Thanks for reading

New touchscreen or a refurb? Same type? (toppolly / sony) Sounds like it's been stripped from an old unit to me as it's not recognising the taps in the right places - can you see somehting like a liquid spill anywhere on the panel? This is what it looks like when the overlay touches the glass.

That was in fact my auction. Looked like brand spanking new to me, not one single stylus mark, and also had the protective sheet on. Of course, I might be wrong
Also, no liquid spill visible anywhere.

I bought from him also and am yet to fit - I got the completley wrong module :-(

What do you mean wrong module ? The "tip" of the flex cable ? Mine seems to match with what was already there ...

Hey NSD!
I purchased the exact same module for my Himalaya device, after the touchscreen being cracked.
My father, who is an electronic engineer, soldered the flat wire from the touchscreen onto the rear side of the LCD with normal copper wires. Unfortunately I have the exact same problem a you!
After attaching the entire LCD (+touchscreen) onto the mainboard, and supplying power from the battery, I'm not able to go past the Align Screen section!!!
The touchscreen is from the manufacture 'Asian Media' (I think so...).
It can't be a coincidence, that both of our touchscreens don't respond to tapping!!!
Anybody been able to get this problem fixed??
Any help would be appreciated!!!
Kind Regards,
Tony Schattat

I never replaced the touchscreen of my BA but I have replaced the screen of my ex ipaq 6315 once.
And one thing that I know is that sometimes the screen align process is different from the normal, I mean, it keeps repeating and repeating again many times....until the unit finally passes the align step and finishes the configuration. Actually I´ve "aligned" the screen more than 30 x (when I replaced the screen).
It happened just once and then I had a completely normal unit.

Battery stuck on 50%

Hi guys, my OnePlus 3's battery indicator is stuck on 50%. I think I must have broken the temperature sensor on it when I replaced the screen. The reason I think that is because in TWRP, the CPU temperature reads something like 1648375974799 degrees. I think because the phone thinks my its temperature is too high, so it won't charge my battery. When I unplugged my phone, it will run for a minute and it would run out of battery.
The funny thing is, I've just replaced the battery. When I switched it on, it read 90% and a few seconds later, it went back to 50% again. I just wiped my whole phone and it still reads 50% in TWRP.
I've tried looking at the parts list to see where the temperature sensor is but I couldn't find it. Is it on the mainboard or the sub board on the bottom of the phone?
Cheers!

I've had similar issues with the Nexus 5 not charging, which was caused by a fake battery (temperature sensor was always reading -30).
Given you've just replaced the battery, it might be the same case. I would first try restoring the original battery, just to rule the new battery out.

Hey there, thanks for the reply.
My original battery had this problem, so I thought I would be able to fix it by replacing the battery which was not the case. So I'm pretty convinced that I messed up the temperature sensor. Was looking for a way to disable or spoof the temperature sensor, or replacing the component instead of the main logic board which could be quite costly.

I'm having the same problem, I was told it is from damaging a super small capacitor that's really easy to knock off. Located right beside the battery connection plug on the main board. only problem is I can't find what the cap size is, to try and replace it. I located the damaged cap no problem and mine is diffently damaged, cracked right in the middle, leading me to believe the info about it being the problem was correct, but the article never gave the replacement info. Anyone possibly know the info for the cap located right beside the battery plug under the screen connection, bottom right corner on the one plus 3 main board?

There are 3 possible solutions for this issue.
1: replace battery.
2: change the ROM for one that changes the Kernel for a version without this temperature protection.
3: fix or replace the main board.
To fix the main board you need to check 2 things on it.
On the left side of the battery connector (under a double sided glue tape foam), there are some SMD. The lowest two are related with this problem. I fix my board resoldering the one on the right (nearest to the connector). Be aware that the SMD is small and when are desoldered, it gets sticked on the double sided glue tape foam. I took a picture of it, but i don't know how to insert here.

Disassembling and repairing HTC HTV31 Butterfly 3

Heey everyone,
My phone has some serious problems. I'm talking about percentage not showing correctly, because of that the phone will go off at random. As the percentage that is shown (for example 43%) is actually a lot less (it's actually 0%). And when I try to turn it on, the phone must be charging, otherwise the chance of data getting deleted is almost 100% (I think around 85%). And with the data deletion problem comes the storage problem, because the data is probably still on there but not accessible by android or something and therefore my phone can't install updates now(the apps are all stock) even though they were on there the moment the phone shut off.
I hope you guys still understand the situation, but now my actual question
Because these problems are all the cause of a faulty battery, I want to replace the battery with a new one.
I couldn't find replacements for our butterfly 3 phone, but there are ones for the M8, M9 and M9+.
These batteries look very similar and I actually think they are the exact same size and they do have the same connector.
Since so many things are similar between the M9/M9+ and our Butterfly 3, I thought those batteries also fit our phone.
But since taking the phone apart is not easy and of course risky, I would like to ask if anyone here has taken apart a HTC (HTV31) Butterfly 3 before.
If so, could that someone please tell me how this phone can be disassembled and maybe even tell me what the size and the connector of the battery are.
I could of course just buy a new phone, but this phone is the only one on the market(!!!) that fits all my needs. And replacing the battery is cheaper than buying a new one. As I got lucky somehow that I didn't have to pay any taxes or anything when I bought it around 1.5 years ago. And the prices on ebay are definitely higher than back then.
If any of you has some other ideas to solve my problem or has a better phone with almost the same specs, then place say so
PS. If it's possible to use the battery of the M9, then I will try to put a larger capacity battery in it, as this capacity is a bit low.

you can go to taobao.com, look for the battery.

Thank you!
The website with the tutorial doesn't load unfortunately, but as I almost bought the battery for the M9, I am happy I now know they aren't the same.
Thanks again.
EDIT: Turns out that the images don't load. Do the images load for someone here? Would very much appreciate it if someone could upload the images somewhere.

I have the exact same problem with my htc butterfly 3
I am looking for a fix of the exact same problems for a long time. Havent found one. If u found a fix plz do let me know

Loss of digitizer responce

I'm not sure where to post this but here we go.
I've been replacing phone batteries for a while now, more of a side project for extra income. I also do board level repairs thought 90% of that is computer related.
So the oddity I have stumbled upon is that after replacing the battery on a HTC One M8, of which I have done quite a few of, the digitizer became unresponsive.
First thought was of course that the ribbon cable wasn't seated properly however it was. In fact everything checked out fine.
I removed the new battery and re-installed the original one and the digitizer returned to normal.
I repeated this three additional times, twice with two older batteries left over from previous jobs plus the phones original battery and the new battery. Each time the digitizer would become unresponsive with the new battery installed and then return to normal when the older batteries where installed.
The battery is the last one of my "New" stock that I purchased just a couple of months ago and none of them have given me any trouble.
This is the first time I have encountered any sort of trouble with a simple battery replacement.
How could a battery be the rout of the problem?
I have placed an order for a new stock of M8 batteries, though I expect the number of replacements to drop significantly, from the same supplier and will be returning this one. They are OEM and as I stated this is the first one that has any sort of problem.
Any idea's? I won't be sending the new one back for a couple of weeks so I have it at my disposal to test. My next step is to try it out on my own phone as it has been close to two years since I replaced it's battery.
Just to add on to the mystery, I installed the new battery into my own phone last night, same thing happened. I left the battery in place and plugged in my old one without any change, digitizer was still not responsive.
I re-installed my old battery and it functioned fine and then connected the new battery while the old one was still installed and the phone functioned fine.
So something is missing with the new battery that is causing the problem. I also noted last night the the physical size of the new battery is slightly smaller.
In any case the company is sending a replacement and it is the only one out of the 12 that I had purchased that has given me any trouble.
Now I really want to know what else is tucked in with the battery that could cause this.

The battery may not be giving enough voltage to power the device hence the problem arises. It's an obviously defective battery. Get it replaced

I would concur with that if it wasn't for the fact that if I leave the original battery in place and connect the new one to the motherboard the phone operates properly.
I'm 100% sure it is the fault of the new battery, just wondering why it would cause the problem when it is physically installed.
The other point is if anyone else comes across this problem I'm just making them aware that it is something to look at instead of thinking it is the connection or damaged digitizer.

Original Huawei Watch charging problem

For the last month or so my three year old Huawei Watch has been either charging very slowly or stays at the same percentage forever. Instead of the charging screen staying on, it flashes between the charging screen and the watchface every second or so. The same behavior happens on both the stock and an aftermarket charger. I have cleaned and verified that the charging contacts on both chargers and the watch are free of corrosion and not cratered.
Before I order a replacement battery, is there anything else that might be causing this or is this the classic symptom of needing a new battery?

I ordered a new OEM battery from eBay and installed it today. The original three year old battery was very swollen, which was probably pressing on the circuit boards and causing my intermittent charging problems. The installation was pretty straightford and the new battery charged up nicely, so I would recommend anyone with a watch as old as mine to go ahead and replace the battery.

Same issue here, can you please provide me the link where you purchased the replacement battery? Also did you replace it yourself or went to a shop.

I got the battery from eBay. Search for the part number HB442528EBC and be sure to pick one that says new and OEM. I replaced it myself by watching this YouTube video: https://www.youtube.com/watch?v=F-JpmRF2AfM and this iFixit page: https://www.ifixit.com/Guide/Huawei+Watch+Jewel+Battery+Replacement/86785
I didn't have a T2 Torx bit or a #0 Phillips bit so I ordered a small tool kit with those from eBay at the same time.
