Does anyone here have a T430 with an upgraded CPU and this screen controller + FHD IPS screen that has no flickering issues?
Yes. I made an in-depth post about it here.

Kit from e-qstore (I believe the original poster) with behind the display mounting, FHD B140HAN01.2, 3840QM, 16GB ram at 1866, discrete GPU, standard 90 watt adapter. Absolutely no flickering issues.

May I ask how long you have the kit? Mine originally was not flickering either, it came after few months of usage.

And it doesn't flicker even when you charge the battery from eg. flat to 100%? Mine does flicker from 1 to few minutes after the charging starts. Apart from that, it's flicker-free.

I'm dissatisfied with the longevity of quality in these AUO panels.

I have a B140HAN01.1 in my T430.
I have a B140QAN01.1 in my T430s.

Within a month of installation they have each quickly developed pressure marks and scratches. I transport the laptop with the lid closed in a backpack, which is normal usage.

Part of the blame, I believe, goes to the flexible nature of the thin lids used in the designs of the T400s, T420, and subsequent models in those lines. These are not "true" clamshell lids, lacking the dust-protection of older models like T410, T500, and the IBMs, and the rigidity of those models with thicker lids (although they still develop defects). As a result the lid and the LCD within are easily and often deformed to flex, which I believe leads to formation of pressure marks and scratches as it bumps the keyboard.

I don't know if other manufacturer panels or specific models are more resilient.

The post was end of October, so most likely the beginning of October. I've been using it as both my primary work and personal machine, so it gets an almost constant all day/all week long use, and also rather abused since I lug it everywhere. If I ever do experience an issue, I will post an update.

I don't think my battery has ever been completely flat. As stated above, it's in almost constant usage every single day. The lowest it ever gets is ~40% on the train to work. There were maybe only 1 or 2 occasions where it was left unplugged by accident and died, but I didn't notice any flickering (not that I would have been looking for it, since I haven't experienced any issues in use). If you notice an issue with the battery very low, it could be a low voltage issue ... though I did have an issue with the laptop completely shutting off with the 3840QM + NVS at high load, but that was with a non-Lenovo and 6 cell battery (vs the 9 cell Lenovo battery). I never determined if it was the cell count or the generic battery, but if you have a knockoff battery I'd be weary of that.

Let me rephrase - does it flicker when you charge the battery? The initial battery value doesn't matter. Flat was just an example.

I have never seen it flicker at all, so no.

It's good to know that it can be achieved, but I wonder why so many of us fail to get that holy grail and have some kind of issues.

EDIT:

I've recently had to replace my motherboard. It's basically 1:1 with the old one (both have flashed modded BIOS v2.78), the difference the new mobo has old MEI firmware and it came with smartcard reader, so I connected it. I don't know if it matters, but I'm mentioning it anyway. The biggest difference is that the screen doesn't flicker at all even when the battery is being charged. Nothing, zero, nada. I have found my holy grail :)

EDIT 2:

It also seems that an issue with battery disappeared. It manifested itself at random times - battery being at a double-digit % charge was reported out of nowhere as nearly empty (between 1 and 3% I believe). OS warning was popping up and after few seconds passed the battery charge value was back to what it was. It was irritating, as I had to set critical threshold value in Windows to 1% otherwise the laptop could go to sleep because motherboard thought the battery was nearly empty. And I am 100% certain it was motherboard because I even ordered a brand new, original 9-cell battery because I thought the battery was at fault here. Nothing changed. Moreover, when I had a 2nd T430, same thing happened, although I'd say the problem surfaced at different battery charge levels if I remember correctly.

Maybe, just maybe, the part of mobo responsible for managing the charging/battery has something to do with the flickering issue, considering that it happens mainly when the battery is charged, not on cable-only or battery-only power.

Panels for fhd mod... A little while ago I did an fhd mod on a 420s using the evan joo kit and a B140HAN01.3 - was able to get a genuine screen (pulled from a t440) from one of the chinese ebay trusted sellers. Sold that one a while ago and have bought a t430 non s. Looking around ebay, amazon, aliexpress etc now, I see the chances of getting a fake B140HAN01.3 are pretty high. A couple of sellers still have genuine screens pulled from t440/450, but at sky high prices, so not worth it I reckon. Given that plus the possibility of flicker being discussed here, I'm looking at a 1600x900 drop in using an alienware TN screen. However, same thing here - looks like lots of fakes around, especially given that the screen in question (LP140WD2 TL G1) is a discontinued model and they're all selling new ones... A few US sellers have what looks like NOS complete LCD covers with screen from the Alienware model, but none of them list the panel model no, just hd or hd+. So, maybe back to FHD mod... Have seen a few BOE NV140FHM-N62 on ebay that might be genuine. They're on Evan Joo list of compatible screens - anybody tried one? (My other thought - and also discussed on this thread - is why not buy an el cheapo that's not on the list?) At the mo, a Trademe NZ seller has the Innolux N140HCE-EAA 1080 panel for sale at $NZ129, but would it work? It's the standard (and pretty low rent!) FHD panel in the t460 I am typing on right now, so has some thinkpad history. Any thoughts, and anyone know some trustworthy sellers with affordable prices??

I installed the FHD kit in my T430, 16mb dual channel memory, and it has worked fine (no flickering). It's only been a few weeks, but so far so good.

I purchased one of these kits from evanjoo as well for my T420s with an i7 2640m and 16gb ram, installed worked for a day then screen turned off and computer rebooted, evan sent me a new one installed worked fine for about half an hour after a pretty delicate install then the screen flickered, went blank then laptop rebooted. Has anyone else had this issue? I have it placed under the keyboard.

Does anyone know if I could get my hands on that cable that goes from the PCB to LCD which could make putting the PCB under the keyboard possible?

According to e-qstore, that cable is not compatible with the older kits where the PCB was placed behind the LCD.

Dang, and I thought it would be possible and fairly easy to get rid off that backlight bleed...

Just installed with the kit from EvanJoo and the screen is flickering nonstop. BIOS and windows logo loads without any flickering, but as soon as the desktop appears it constantly flashes black. Should I just request a new kit?

Well this is certainly odd. When I boot to desktop, the display does not flash. As soon as I open any window, the display flashes black. Any ideas?

it s hard to imagine it will be software related honestly. you are all running windows? can you try with a linux live cd of choice to see if the flickering persist? would be nice to have someone running coreboot as well to provide us with feedback.
