I have Xiaomi Redmi 3S with cracked screen. I tried to change Touch+LCD to new one. But now lcd works good but touch doesn't work. I noticed that on my old LCD flex part number is:
BV050HDM-N07-3800_/_R0.6
On my new lcd it is:
BV050HDM-N07-3800_/_R0.5
And on old touch flex part number is: 050-5846 V1 of 2 1628
on new touch: YZ-CTP595 (HM3)-F PC-V1.0 160301
So touch part numbers are diferent and I think there is the problem. It is posible to change phone touch drivers or do anything else to fix this problem?

hi to all,
some day ago i broke my screen, then i bought a new one and replaced it. Only at the end i saw that my old touch screen was synaptics and the new one was Atmel. My old touch screen doesn't work anymore and even the new one doesn't work.
On my phone there is installed slimbean 7.2 probably without Atmel drivers; if i install a stock rom, will my touch screen work? if not, how can i do?
Please help me
Hello to all my guys HD2 after some months of inactivity, yesterday I turned back and I found the surprise ugliest in the world, the touch does not go, can you tell me what can I do? to make it work again?
EDIT: if I hold the touch screen floor of 1 inch from the shell of the phone the touch and that it works beautifully.
EDIT 2: I tried it with the tester, and if I measure the frequency of current flowing from the motherboard to the screen with DCV 200 and 0.29 so it's not a motherboard problem (or rather, it seems to me that it is not)
check digitizer connections & lcd ribbon to mainboard & if all look ok & reseating them makes no difference to digitizer function then expect new digitizer is needed.
Not expensive & also very very common for digitizer fault on HD2 ...
Hey guys,
yesterday i changed the screen and digitizer of my Mi2S. Now, when i switch the phone - with new screen - on, the screen is just lightning blue (you can see it on the attached picture). Now i saw that on the Flex Cable of the original screen, there's written B04 and on the new screen there's a B01 instead. So, i think i have now a different version of the screen and not having the drivers for that. So, does anybody (maybe developers) know how to flash others drivers and where to get them from?
Thx already ahead for any help.

*already edited it into the first post*
Are you sure you connected both flex cables correctly?
From your picture I would think only the backlight is on and the screen itself is not active...
Would be my first guess...
(I have a Xiaomi Mi2s and did the swap myself, I didn't have any problems... + even if there are different screens, the SW should cater for it, otherwise we would have a different SW build for every screentype used...)
Hi, i send it to a professional repair center and they said that there was a small water damage (from wherever!?). As i now found a pretty ok priced Mi2S (where the camera flex cable is damaged) on Ebay, i'll just insert the camera of my old one into the "new" Mi2S and sell the Display i bought for my old one. Problem solved!
But thanks for the reply anyway!
Hi all,
I have uncommon issue after replacing digitizer in my phone. When I connected new digitizer, the device doesn't boot up, when I connect previous, crashed one, everything works fine. I found out that the chip on ribbon has different symbol but seller said it's "original one from grand prime duos and it's compatible with grand prime".
Chip on original digitizer - BT541C
Chip on "compatible" digitizer - Synaptics S5000B-5
First, obvious thing is there are not compatible and the replacement is just a fake...but how this guy could sell a lot of that digitizers and nobody could notice any issue with it?
Should I somehow "setup" my phone with new digitizer or buy a new one, with excactly the same chip?
Try downloading the kernel source code and building it with that chip module, however I don't think that might work so yeah...
Yeah if the module on the digitizer is different it's not going to work, your salesman is lying to protect the sale. You need a digitizer that's set up with the same module as the original digitizer buddy
My Xiaomi Redmi 3s's old screen was broken so I imported a new LCD+Touch-screen with frame from china. After fixing the new LCD, display is working perfectly but the touch screen is not working and the surprising thing is the touch screen of the new LCD is working when the phone is connected to a charger! When I unplug the charger the touch screen stops working.
any Idea why its happening? hope someone could help me.

It could be because the touch screen isn't well powered

If problem persist you need to change the PMI ic or re check your touchscreen vcc ways
