Not sure if this really should be going to the noob friendly thread, but since it is a couple of questions covering various Android related issues, I figured that I will make it a separate thread after all.
1. Sometime updating an Android version would also end up updating the bootloader, at time rendering it impossible to downgrade again. Can this also happen in custom ROM (e.g. Lineage). I am asking this because I am thinking of custom ROM with newer Android version on my Galaxy S7, but may want to revert to a relatively old Android 7.0 after I am done testing.
2. Do file systems (the way application, application data are stored in the system and other information) etc. tend to stay the same as stock for a given Android version? For example between stock Android 7.1 and Lineage 14.1.
3. Same question as question 2., but between major Android versions (e.g. stock 7.1 and stock 8.0).
4. On rooted devices, can you usually update major version update without losing any data, and is it usually trouble free?
Feel free to skip reading this part, but for some background information, the reason I am asking all those questions is because one of the app I tried to restore via Titanium Backup and Swift Backup both failed. The application itself launches properly, but as soon as I restore the data, it would instantly crash and close. My guess is that this is probably caused by attempt to go from Android 6.0 to 11.0. Maybe it is the backup software or maybe something changed in the way files are stored, but whatever the reason, it just won't work.
So I am thinking that my best option is to try it to restore it on an Android 7.0 phone that I have (also on the way to be retired, and if it works, update to Android 8.0. Since Android 8.0 was the last officially released major version for that phone, and I was thinking that if it does work, perhaps I could alternatively go for an early Lineage ROM, then make gradual updates up to Android 11.0 and see if it helps the app remain unbroken. And then if it does work, perhaps I could then make a backup then restore it on the other new Android 11.0 phone that I have.
All in all, it is a silly amount of work to do just for one app.. but it is important to me, so I will exhaust every option that I can think of to find a solution.
Thanks!

First of all, i hope I'm not the only one in this forum!
I just found my old cellphone and want to get most of it, and good to mention now, there is almost noway to use any application because this is an old Android rooted version. I even not able to use my google account to get google play!
I know what download and recovery mode are, but it's shame to say i don't know how to get there in this phone! believe or not there is no file manager here! Now I'm thinking how did i pass days with this phone!?
I did a reset factory and hoped to see some improvements, but nothing got better!
So if anyone here and read my post please help me to get a fresh start
Android Version: 2.3.3
HTC Sense Version: 2.1
Baseband Version: 12.56.60.25U_26.10.04.03_M
Kernel Version: 2.6.35.1-gd2564fb
Best advice: start reading the threads in the General section. There should be multiple threads on how to root and to get S-Off on this device.
Custom ROMs up to Android 6.0.1 are available, and I currently have Android 5.1.1 on my roommate's old phone. However, on these old devices bootup times run nearly ten minutes, not including app optimization, and overall performance suffers. Android 6.0.1 will not install at all unless the /data partition is moved to the MicroSD card as the /system partition is too small.
If looking to tinker, the unofficial build of Cyanogenmod 12.1 for this device is likely the best option, as there's no need to move the /data partition.
EDIT: Did not notice the date of the original post.
Hi.
I have some issues with Nougat, because it seems that some system files are missing after updating from Marshmallow (cannot uninstall completely with 3rd party apps for example).
Phone is working good generally, but if I need to flash again the ROM to reinstall all system files without losing my data, is it sufficient to use firmware finder and do the usual operation with the ROM MF only?
This ROM, by the way, is smaller than MF-PV because I think it has less files, considering the fact I am already on Nougat and EMUI 5.
Am I right?
Please let me know if some of you already did this operation, I wouldn't like to make some bull....ts flashing in the wrong way...
I am coming from Samsung world, and flashing is generally easier (apart that they release the kernel source quite quickly).
Thank you

Once backup all your data and do a factory reset. Hope this will solve your issue.
So, I happen to have a bunch of old Huawei phones (Mercury and Ascend) and I want to use them for cameras for a security system. They are running Android 2.3.6, which we all know Google won't support and therefore it has become a major frustration to try and get any apps loaded on them. Does anyone have any suggestions on how to update them with a custom ROM that is Android 4.1 or newer where they can have the apps loaded? Or, if there is a way to get the apps loaded without an update to 4.1 or newer, I'm open to trying that as an option. It seems most of the custom ROM links don't work or were blocked by the a$$ 0's that want us all to pay for stuff that we already own.
It's been a long time since I've updated my phone and I've put it off additionally because I assume it'll be a nuisance. I'm on Omni version It's been a long time since I've updated my phone and I've put it off additionally because I assume it'll be a nuisance. I'm on Omni version 9-20190331-oneplus6-WEEKLY and think I may have never correctly rooted it, evidently by opening the TWRP app and Titanium Backup have issues so I have at least a couple concerns:
What ROM should I upgrade to? Thinking something like Lineage
How do I correctly update up Android 10 - then 11?
It's been so long since I've done this, are there other items I'm not thinking of?

You can go to omni A10 if you like. It is much better to go A10 ROM for stability but if you like A11 ROM it's up to you if bugs and issues does not bother you. But prior to upgrading you must upgrade first your base OOS to at least 10.3.9 in my opinion because 10.3.10 and 10.3.11 have issues in some people.

In my view, stock is the best option. The next release will be Android 11. However, if Custom rom's are your choice. I'd prefer to go with MIUI and my second will be Omni or other Enchilada versions. As they tend to use Google apps which in my view is not user friendly and intuitive to use. The most stable ones of them will be Lineage OS . The latest versions can be found over this forum.
I have a regular OnePlus 7 PRO (GM1913)
My bootloader is unlocked and I am rooted with Magisk on Android 10, with Oxygen 10.3.4 Stock.
something got funky with switching between apps and keyboard gets stuck sometimes and camera crashes, could be Nova launcher, could be Swiftkey, idk really
but I guess its time for a refresh to see if that fixes the problem (which I believe it will).
My Questions are:
1: How would I go on about flashing a custom ROM / latest Stock (recommendations welcome) without wiping data and keeping everything intact?
2: do I need a PC for that or can I do it "Over the air"? (sorry not fluent in this stuff since a long time)
Thank you!
Well, I'm not an expert but I've done that for the same reason as yours; ended up with the stock OxygenOS. Actually it started with stock OTA updater, ended with a brick(then unbrick)...
I've tried several custom roms, but
stock camera app is irreplaceable (Custom OS got more options, but Android 10+ is difficult to tinker with)
Even the most popular custom OS's may crash with an upgrade (especially if you tinker with your system). So whatever is wrong with it now, may got worse, or better.. Or it may get worse later(or not, who knows).
OTA doesn't do downgrades and check the signature of the package, so if something goes wrong or if you want oos back, you may need to use EDL with MSM Tools(Which, unfortunately requires a PC)
Thats why your safest bet is to:
Backup everything you can't afford to lose, then prepare an unbrick tool image if you can. You can backup without pc, but using edl or fastboot requires PC or other android device as a host device.
By the way, It's not that fun after a hundreds of reboot and flashes, so I use Linux now
