No response touchscreen

A little background:
I have a 2012 Nexus 7 that I gave to my 6 yr old after I got the Nexus 10 - he's taken pretty good care of it, but recently the screen came up cracked. I went ahead and ordered a replacement screen in addition to a new battery and USB/audio port. (Since I was going to have it apart, might as well replace all the stuff in one go, right?)
Fast forward.
Device back together and boots fine, however the screen will not respond to touch input. I didn't think he needed a rooted device and it was interfering with getting OS upgrades, so I went ahead and restored it to stock a while back, however this has caused me to be unable to access his data which I plan on moving over to my Nexus 10 after I get my new Nexus 9. (he'll get the 10)
To the point:
Does anyone know of any particular reason why the screen won't respond? I read something about a driver incompatibility with Lollipop, but really unsure how to proceed without losing everything. Any assistance would be appreciated. I'd also like to sell or re-purpose the 7, but right now it's essentially a brick.

Was the screen touching at all after being replaced? You may have purchased a defective replacement. It does happen, I know, as this is my line of work. Make sure all of the cables are properly seated as well. Did you purchase this from a reputable seller? Perhaps they will work with you on an exchange.

Got it from Amazon. May look into a replacement, but I'd like to know if anyone has any experience with the Lollipop software issue before taking it all apart again....

Revert to 4.3 from 5.0.1?

Greetings. Not sure if my question belongs here or under Development. I’ll post here first and see how it goes.
My question is this: Is it possible to revert from 5.0.1 to 4.3?
Long-winded background:
I bought an S4 about 2 years ago brand new. Loved the phone. I rooted it that day and I had full control over exactly how it was setup. I never felt the need to run anything but stock ROM. But I’ve flashed countless ROMs on other phones I’ve owned over the years. I’ve rooted probably 4 or 5 different phones – some easier than others. And I’ve performed jailbreak on iPhone and iPad. In summary, I’m not a total rookie to this kind of thing.
My original S4 took a swim when I had to jump into a pool to rescue my 2 year old, who fell into the deep end. The phone was in my pants pocket. The chlorine in the pool really did a number to the internal circuitry (not a huge surprise), and it's trashed. I liked my original S4 so much that I decided to just buy another one. Three days ago, I picked up a used S4, but it’s in EXCELLENT condition – looks brand new.
When I got home after purchasing the replacement S4, I realized that, beginning with Android 4.4, text wrap/reflow is gone. My phone is running 5.0.1. I found that Opera will still reflow text, but I’m not a big fan of Opera. To each his own, and Opera is not my own. I prefer Boat, Chrome, or Firefox. And none of those will wrap/reflow text.
This is a big deal for me, for what I do with my phone. I am pretty much willing to do whatever it takes to get back to 4.3 to enable this feature.
So, does anyone know a) if it’s even possible, b) how to do it?
Thanks in advance for any helpful advice/suggestions.

Coming from Note 4 with a couple of question

I just picked up the V20 and am in the process of trying out some non-root backup/restore options. I'm thinking of running stock, non-rooted on the V20 for a bit to see if I even need to bother with root anymore. Does anyone have any pro tips on using LGBackup or Helium? My note 4 is rooted and does nightly backups with Titanium, so I'm thinking if I can't get one of the non-root restores to work I'll resort to rooting just to get my Titanium backup on there. Is there a way for Titanium to restore without root maybe?
So far I've found the LGBackup is just stupidly slow. The reviews were hit or miss on if it actually moves over app data. Still waiting on a small test restore to finish to verify.
Any other note 4 to V20 users with some tips on settings or anything? This is my first non-Samsung phone and also a big upgrade in terms of OS. Was still running 4.4.4 on the note 4 because I'm lazy on manually upgrading the ROM, that's why I'm hoping to not root/rom this time round.
EDIT: Another possibly stupid question, could I root to get the Titanium backup restored onto the V20 then unroot without wiping the data? Basically my goal it get my app data from note 4 to V20 and still be able to get OTA updates from Tmo or Google.

I'm pretty sure you don't want to restore a Note 4 backup to the V20. Some of the apps use different hooks. To be honest, I wasn't a fan of TB backups when flashing new ROMs. I had much better luck just reinstalling the apps from the Store.
TB won't run on phones that aren't rooted and I'm sure that any unroot methods would involve wiping data.
I've had the phone since day one. I haven't yet had a compelling reason to root. Your mileage may vary.

Even the data wouldn't be compatable? I've seen how Helium can just do the data, so you can download the app then restore just the data. That's going to be my next test. LGBackup took ~3 hours on just personal data and 5 test apps. No app data was transferred.

just a heads up. I dont know if this issue has been solved or not but.... if you are planning to root the phone and in the near feature you want to unlock the simcard, i suggest to unlock it prior to doing the root because many people have been trying to unlock their phones and even when they go back to stock it will say that the device is not supported.

Go back to your Note 4. Trust me I regret getting rid of my Note 4 for this POS. Went through 2 v20's already and waiting for my 3rd replacement as this one just died.

I've restored LGbackups several times and it worked far better than sammy smart switch or kies. It restored all my apps and app associated data.

The v20 will be faster (about 3 times faster in benchmarks), has more ram, less junkware, more storage, quicker camera, faster charging and better screen.
Only thing missing from the v20 is the stylus. I honestly wish they'd make the v series a stylus version and the g series a non stylus version akin to the Samsung S series and Note series.
As for note 4 backup on a v20 I don't recommend it because Samsung is known to customize the crap out of the android system. I am not sure if they still do this but I know kitkat was heavily modified (specifically ART component) on the note 3 enough to require rework on aftermarket options.
Further v20 is on Nougat, I believe the note 4 was updated to the last version of lollipop so that could create some issues.
As for backing up I recommend 3rd party software like Titanium Backup because manufacturer backups tend to go with the idea you'll stick with their brand forever.
SaintZ what exactly happened to your v20s? I find it interesting you've gone through so many bad ones certainly not normal.

Need help updating a device that has been physically modified (fixed a broken screen)

Hey guys, I haven't been on XDA for years but I'm really in the need of some help... I wounder if you guys have some solutions!
I used to have a Sony SP, the thing broke and I decided to look for a replacement. Buying a new phone wasn't in my budget so I went and looked for a Samsung S4 that had a broken screen, bought the replacement OLED (I think it's an oled display), and took it to a technician to repair it. It was a good buy but little did I know that fixing the hardware on the device will disable my ability to update it! I've wanted to stay stock and not flashing any ROMs on it because I just want a phone that works. I don't want the hassle of having to worry about the latest firmware, and flashing new kernels, I just want a laid back experience. My phone was already rooted when I got it, in fact I had the SuperSU app already installed (which I thought was pretty weird but I didn't think much of it), everything else is stock. Is there any options so that I can update my device that don't require any flashing on my PC?
I have another phone with the same issue, my mothers Samsung S3. Full story, I live in Venezuela and smartphones here are extremely expensive, so obviously if something happens to them you much rather repair it then buying a new one because it's unthinkable to afford one, besides a Samsung S3 is still a good device. So one day the phones screen starts fading black, and it stops accepting touch input, we had to replace the digitizer (Touch Screen), and it functioned like normal! Problem is we needed to restore the device because it was getting a bit bogged down, low and behold, same issue as my Samsung S4. Now I can live without having my firmware updates, but I'd really like to at least help my mom get hers sorted out!
I want to thank everyone who took the time to read this, and that can help me fix my devices!

The reason you can't update your S4 is because you're rooted.
As for the S3, maybe there aren't any updates available.
Samsung stopped updating the S4 like two years ago at Android 5.0 and I don't think the S3 ever got Lollipop.
I'm also pretty sure that replacing a screen won't magically prevent your phone from receiving updates; The restore may have caused that.

Longevity

I've been using my OnePlus 7 pro since it first came out. I bought it when OnePlus offered it for sale at a low price and I loved it, from day one.
I am one to try different ROMs and Kernels but for the first time in Android history I was satisfied with Oxygen OS and didn't need a custom ROM. I do like to root the phone to use TWRP and Titanium Backup.
Somewhere along the line I thought I had bricked the phone. No matter what I did I could not get it working again or even run TWRP. So, as a last result, I decided to get another OnePlus phone, this time the 8 pro.
While using the 8Pro I learned of an app that let restore the phone to factory settings (MSM?). I tried it and I had my 7 pro back. Since I was using the 8 pro I decided to have an extra cell to use with wifi and the 7 went to live in my bedroom where I would use it nightly.
After a while, Android 11 came along and I could no longer use TWRP on the phone and it became overly difficult to root with magisk. After a while the 7pro got it working but never the 8pro. Not only that but the Bluetooth interface with my hearing aids started to malfunction regularly and this became a major headache. So I switched the SIM from the 8 to the 7 and everything works great and I'm so grateful it was able to be restored. It is head and shoulders greater than the 8pro and it as good as new.
I'm a little disappointed in OnePlus as they no longer offer regular software updates to their phones, and I'm pretty sure I will return to Google Pixel phones next time. I will sell the 8 and put the 7 in the bedroom as I have become accustomed to having one up there. I'm sure I can still depend on the 7pro for a long time more. I may switch to a custom ROM that is regularly updated unlike the OnePlus phones. But despite that, the 7pro is one of the best phones I've ever used. The 8 was great too, but just not for me.

They use the dual partition setup, which makes it more challenging for TWRP to be built.
What this means is that if you see an "OTA" update, you probably shouldn't jump on it and immediately install it. I did that once. After that I could not install TWRP because the phone had been updated from 10 to 11 and the TWRP team hadn't had time to release a new version yet.
Probably good advice on any phone though.... updates CAN stop you from having a rooted device, at least temporarily until a custom recovery is released.
As for my OnePlus 7 pro, i couldn't be happier.
I'm really glad that I paid the extra $200 for it on the OnePlus website.
Because that enabled Accident Protection.
At the end of the two year period, I set an alert to remind me, I called OnePlus and told them that i broke my back glass. They said No problem, send us the device and $75 deductible. Within 3 days I had my replacement device. Sure, it's probably a Re-man, but after 2 years of strong service and now I get a refreshed device??? I'll take it!
