[Q] Installed TWRP. I have questions on it's use cases. - General Questions and Answers

I am new to android. I got sick of apps not being able to write to my SD card so I eventually got the guts to attempt rooting (which worked) and then I even convinced myself to try and install TWRP because I heard I can type commands in there to get my device still rooted after encrypting since superSU does not work after encryption (not tried it yet).
I updated to a new version of TWRP 2.8 I think? Any way, what kind of safety net do I have now? I am in the process of doing a fresh backup (everything ticked) with this new version of TWRP and I will trash the old one once this is done. I had zero intentions of flashing custom OS' on my Galaxy S4 mini (I9195 LTE) for fear of bricking my first ever brand new android phone.
Once this backup is created (and duplicated on every damn hard drive I have for backup purposes...) what kind of protection is this? Could I experiment with Cyanogen Mod and have no fear of it failing to load, have problems with it once installed, something go wrong and phone won't boot up? Would I be able to load my backup into TWRP and magically the phone would be in the state it is in today, rooted and everything?
If there are any things I should know I would appreciate being made aware of them before I dare proceed with any (what I assume would be potentially dangerous things) flashing custom roms etc because I want to always ensure I can get my phone to exactly the state it is now, with all my google apps still installed and everything. With everything ticked on my backup, is there anything that wouldn't be able to be restored, as in apps/data or anything?
Sorry for sounding like a noob, but as far as android and flashing is concerned, I am a noob.
tldr; Essentially I just want to be informed, as well as I can be, as to what I can now do (that I have TWRP installed and made a backup) and what I still shouldn't do, what isn't covered in a backup with all boxes ticked etc.

The backup covers /system (Android OS with settings) /data (all user apps with settings) /EFS (Latest TWRP should backup this, too - MOST IMPORTANT as it stores your IMEI and baseband code) /boot (kernel) + caches (not that important)
In any case your phone has a "DOWNLOAD" mode integrated in the bootloader that will allow you to restore all partitions except "EFS" by flashing the stock firmware via ODIN. So as long as you have a EFS backup and nandroid backup and you don't screw up the phones bootloader (You could do this by flashing a firmware for another (incompatible) Samsung model via ODIN) you're on the safe side. You stock rom backup or a custom rom backup can easily be restored via TWRP. Even if TWRP brakes, you can flash it again via ODIN as long as your bootloader is fine.

Ok, so Odin is the only thing that could screw my phone up, given that I have a backup? What about if I attempt to install an incompatible rom via TWRP? Is that just as dangerous? Also if I were to some how screw up the bootloader, how would I fix that? In what circumstance might the bootloader get screwed up? From putting a custom mod on? Or is the bootloader getting screwed something specifically I would have to foolishly mess with?
If I download a cyanogen mod zip file and do the install through TWRP, would that essentially wipe everything and start completely fresh with the new OS as a virgin clean OS? Then I am correct, I hope, that if I want to get back my phone how it is now, with the stock firmware, rooted I would just do an install on TWRP and choose the backup and it would just make everything as it is currently? Even if it were screwed up and unable to boot into an OS? If that is the case, I would be a lot more open to trying different mods.
If I do try a custom rom like Cyanogen, is there an official way to get the google apps like playstore and gmail etc on it? I have seen random guides with strange links like "trust us this is a legit download!" Hmm...
Sorry for all the questions guys, I am just trying to become educated on key things before I attempt any other further things.

Asking is good. Better safe than sorry
Yes, in case flash TWRP via ODIN, restore the backup and you should be fine.
Bootloader repair is about 40$ on ebay.
. Before flashing any new (different) rom,perform a NANDROID BACKUP" + manually internal SD Crad backup and then a FULL WIPE (/system /data /cache /dalvik cache /internal SD (Virgin like)
- If you just install a newer version of the same rom e.g. 03/01/2015 -> 03/14/2015 you only need to wipe /cache /dalvik cache (Not so virgin like)
- You can restore all apps/settings from NANDROID backups with "Titanium Backup" on your new OS
- I never heard of flashing a custom rom via recovery messed up the bootloader on Samsung phones, (In rare cases the EFS but you got the backup)
- Use only THIS GApps and make sure you pick the right version (For Android 4.4.x / 5.0.x / 5.1.x) -> Smallest (Pico bundle) will totally do it, you can install any other needed apps (also google's apps) from the pklaystore. Legit and safe.
Make sure you READ and UNDERSTOOD everything before you start flashing a custom rom.

Oh I will read everything before trying anything serious like this. I felt as if I was smashing my phone into the ground when I rooted it lol, so dangerous :S, even though I was following a guide. But now that I have all the tickboxes ticked and backed up and I have also copied that backup to 2 different hard drives... I should be safe with that.
So for my additional questions.
Is it possible but unlikely/impossible etc that a custom OS rom install through TWRP would break TWRP to the point of being non-functional to perform restores? (if so I know I could follow the guide again to install TWRP again)
Just to clarify, I should wipe everything except EFS right? When I do a completely new OS rom, perform the install and it should work or it will break. Regardless if it is broken and non functional OR it worked and I don't like it for some reason, I do the same thing again, boot to TWRP, format everything except EFS and install my backup and then the next time my phone is ready for use it will be as if nothing was ever done to it. Does that sound about right? If so, I might have an experiment with Cyanogen.
Also, you said you never heard of the bootloader being screwed over by a TWRP-based rom install. Does that also cover incorrect roms for a different model of the handset or completely different phones? I guess what I mean is, is it safe to perform an OS mod install via TWRP (in case you got the wrong one) and more dangerous to do it through odin if it is the wrong one?
I have a Samsung Galaxy S4 mini GT-I9195 LTE. I see the latest "stable" release is only version 10 of cyanogen mod? Yet there is v11 and v12 versions all without any stable release. Does that mean 11 and 12 won't work on my S4 mini or that it would be a mistake to install it on my phone? Or is there a method I can tell which one would be the best one to get for my phone (newest best)?
Lastly, as for odin, since I have TWRP and a backup of my phone as it is now, is there any reason to use odin for anything other than maybe reinstalling TWRP? If so, what else would require me to use odin that TWRP couldn't do?
Thanks so much for answering my questions, it is really making me feel more confident with the whole process. I don't like going into things blind, I'm a computer techie and like to know what I am doing and why I am doing it. This phone customization business is entirely new to me beyond changing settings and themes lol.

Is it possible but unlikely/impossible etc that a custom OS rom install through TWRP would break TWRP to the point of being non-functional to perform restores? (if so I know I could follow the guide again to install TWRP again)
--> You could flash a wrong zip containing a recovery (Probably you will not do)

--> Stable means NO BUGS, Nightlies are updated nearly every day with the latest commits as they are in development status. May or may not contain bugs. Check out the specific rom thread on xda. Stability of the rom / bugs are discussed there by the users every day. So you can check out which version will work.
Lastly, as for odin, since I have TWRP and a backup of my phone as it is now, is there any reason to use odin for anything other than maybe reinstalling TWRP? If so, what else would require me to use odin that TWRP couldn't do?
--> Restore the phone to fully stock firmware. Such official firmware can be found at SamMobile.com
And most important: Press "thanks" at the botom of my posts

(had to remove quotes due to outside links preventing my posting.)
If I were to flash a stock firmware rom with odin, would it destroy TWRP? At which point I could flash it back on again? Or would TWRP still be there?
I think I am going to actually try Cyanogen, once I decide on a build to try. Are there any "minimum requirements" for cyanogen major versions? Like I could see I shouldn't install CM12 on my S4 mini and should instead try ones prior to 12? Or is it pretty much just a features and updates thing and 12 would work just as effectively (in terms of just "working smoothly" discounting any bugs etc) as 10?
Thanks button pressed on them, because truly your information is extremely helpful.

--> TWRP will be replaced by the stock recovery. You can instantly flash TWRP again.

--> Your phone got enough permorfance to handle any kind of android version available. Bugs and performance are rom related.

So when they say 5.x isn't coming to the S4 mini, that's a sales thing only?! Not based on performance limitations of my phone's hardware?
EDIT: Should I wipe Preload?

Just like that. I use 5.x on both of my phones
Galaxy Ace II -> performance is okay, with 4.4.4 it runs as hell, better than ever with stock firmware [Last official Android is 4.1]
HTC One S -> Flying on a Lollipop [Last official Android is 4.1]

I am having trouble finding any specific information about the S4 mini LTE and CM12. I don't know if I should try the last version of CM11 instead? Not sure to try a CM12 or CM11 at the moment. I am sat here ready to perform the wipe but I just can't make my mind up which to try :|
Which reminds me, if I use the latest CM11, will there be any further security updates and things? Or are updates only on the nightlies? I would hope they will update CM11, I'd hate to think the only way you get updates is on the bleeding unstable edge :S ?

Possible security issues can be fixed later by modules. By the way, stock firmware is also updated just a few times and stays at this state. If you want as less trouble as possible a CM11 variant will be more sensefull for your purpose. Feel free to get some more informations HERE

I am on the latest CM11 snapshot Amazing! Although I am confused by some of the options. Is there any documentation on the OS? I see for Network modes things like "2G | 3G", or "2G | 2G + 3G" and "2G | 3G | 2G + 3G" . I pretty much can assume I know that 2G | 3G means 2 or 3G but when it comes to ones with +'s that is just confusing. 2G and 3G at the same time? No idea lol.

Unfortunately the compass sensor does not work. I may have to either risk trying a CM12 or go to CM10 :/ What would you recommend?

2G = GSM Data
3G = UMTS / HDPA / WCDMA Data
Do you often need the compass sensor?
SlimKAT is a fast, lightweight rom and should be working.

Not always but when I am using offline navigation software, it is very handy to see realtime if I am pointed in the right direction instead of having to wait for enough distance to be detected to determine what way I am pointing. I don't like limitations. Period. That is the root of why I am messing with... well, root and roms. I could not use software to write to my SD card because of some security "enhancement" which just crippled the functionality of having an android phone. First I rooted and used SDFIX or what ever it is, now I am testing roms to see if I can find a good one. I have the latest (this year) stable AICP installing and gaps currently. I will give this one a whirl and see what I think. I was disappointed that I could not find a nice "Hey.. this is why you should choose our rom!" page. Nothing. Just a download link and ability to get the source code.
I want to read about all the amazing reasons and features why AICP (or any rom for that matter) is a great choice. But I found no such page.

If you can't find any custom rom that fits your needs, you can also choose a modified (debloated) stock firmware if you need 100% functionality.

[Q] Note 10.1 4G N8020 messed up

Hi all. Tried my first root + custom rom installation and i messed up the device..
i had the newest KIES firmware update (phone XXBMA5) and (XXBMA6) and i rooted the device with odin (3.07). That went OK.
Then i installed the CWM recovery with odin and that was OK too.
Then i downloaded the latest Omega Rom (i missread that it supports N8020) and followed the installation instructions to the point where it started installing Omega V2.0 from SDCARD and then it asked me to select device from a list that included only (N8000,N8010,N8013)..
So the situation now is that i have working odin, working CWM and backup of the EFS (img+tar) but no working recovery. i live in Finland and the device is Sonera locked i think, so the stock roms (international) do not work i guess.
KIES has a backup of my Note but i can't even get to a point where KIES discovers the device.
So basically i think i need a working ROM for my model (Note 10.1 4G N8020), or can i recover the original samsung software somehow ?
Any advices ?
Removed
Just a thought, but can't you reflash CWM or the stock recovery?
If you didn't install the rom why do you need to re-install anything. Just powering down and powering up should have left you as was....

working CWM .......... but no working recovery.

Maybe i'm missing something but isn't CWM your custom recovery?
It doesn't sound like you've actually installed any rom yet.The Omega installer doesn't actually install anything until a few steps after the one you mentioned about the model type.
I'm with ultramag69 on this one. You should still be on a stock rom unless you already wiped your original rom.
Hi again. Problem solved, just had to do emergency thing from KIES. Like i said this was the first time trying root + custom ro install and to be honest it went to ****. Somehow i managed to delete the stock firmware so that is why the recovery gave me (no files). I did make some backup but when tried to restore it said MD5 mismatch or something. At first the KIES emergency recovery could not find the device, but after i switched from CWMcto stock recovery it worked.
So what did i learn from all this ? Nothing, because i am getting too old (tired+lazy ) to do proper investigation. So one could say my strategy is to bang my head to the wall as long as it takes to go trough. Even if i could just go around it
So basically i am now at the point where i started, with stock 4.1.2 rooted. Used the triangle away to wipe the (6) custom installs or something away, but it still says custom in the settings> information. Does this mean that OTA won't work ? Any way around it ? Because i would like to check now and then that is my version of android the newest one..
Could someone recommend a custom ROM for my Note 10.1 4G (LTE) N8020 4.1.2 because the only one i was able to find was the CyanogenMod (or something) and it basically makes the S-Pen (almost) useless. What i would like is the Omega ROM, but like stated before the installation only supported N8000, N8010 & N8013...
Added screenshot from info.
Thanks anyway
What is truly amazing is that i did not brick the device tough..
switch from cwm to stock

How did you switch from CWM to stock? I have having a problem syncing with kies also using omega rom on n8013.

I was not easy, i just tried the download mode over and over again with KIES open in windows and somehow it finally did find my device and offered a emergency restore. That is it, and the device was restored to default "original state".
OMG.... one would think after nearly having bricked your device you would either A) stop messing around with it or, B) read and learn more about what you're wanting to achieve and THEN maybe trying something with the ABSOLUTE certainty that a backup to restore is available to you in case of any mishap!
Moral of story :
Don't do anything until you are absolutely sure you have read EVERYTHING about what you are going to do.
For others wanting to mess with their devices, take heed! You may not be as lucky as OP (or troller) whichever is applicable.
There comes a certain point, that when crossed one does not care what happens to the device at hand. After fighting with my n8020 for several days in a row i couldn't care less, and like said before i dont have the level of enhusiasm like i had when i was younger. Of course i know now what went wrong.. But seriously, these are just overpriced toys, so it's not a matter of life and death.

[Q]About rooting and flashing ROM (a noob asks)

i'll try to be brief:
-if i root my phone (s3 mini), will samsung updates cause problems? would you suggest that i also flash the ROM (to smth custom like cyanogenMod)
-does the utility to root the phone provide a full backup of the stock firmware and data? so, if smth goes wrong i can revert back to stock (with my apps and settings. at worst, default factory settings).
-if i flash the ROM, will i lose anything? -say- will i lose proprietary stuff like touchwiz?
-do custom ROMs use the latest android version (that's one of the reasons that i wanna root & flash: to be up to date to latest android version)?
-can custom ROMs update to newer android versions automatically? or do i have to flash again and again everytime there is a new android update?
When I rooted my Galaxy S3 the status of the phone (visible in the preferences/device info) changed to "modified" and I stopped getting updates from Samsung (when checking for updates it said that I had a modified system so I wouldn't be able to get any updates). If you flash a ROM you will indeed loose everything, including Touchwiz, but if you backup your personal data then loosing Touchwiz could be a good thing, at least it was for me. I prefer Cyanogenmod.
Flashing ROMs is frequently done because you actually want to loose all that proprietary bloatware. Custom ROMs also can give you access to the latest Android version right away, wich is a lot faster than waiting months to get last year's version through Samsung. This is one of the main reasons why I decided to flash my phone. I don't use all the "features" that Samsung implements and with Cyanogenmod 10.1 my phone feels faster and has longer battery life.
As for updating, each ROM has different ways of handling it. Cyanogenmod has OTA updates which you can access through your phone "Settings/About phone" section and it will automatically flash them for you.

i'll try to be brief:
-if i root my phone (s3 mini), will samsung updates cause problems? would you suggest that i also flash the ROM (to smth custom like cyanogenMod)
-does the utility to root the phone provide a full backup of the stock firmware and data? so, if smth goes wrong i can revert back to stock (with my apps and settings. at worst, default factory settings).
-if i flash the ROM, will i lose anything? -say- will i lose proprietary stuff like touchwiz?
-do custom ROMs use the latest android version (that's one of the reasons that i wanna root: to be up to date to latest android version)?
-can custom ROMs update to newer android versions automatically? or do i have to flash again and again everytime there is a new android update?

When I rooted my Galaxy S3 the status of the phone (visible in the preferences/device info) changed to "modified" and I stopped getting updates from Samsung (when checking for updates it said that I had a modified system so I wouldn't be able to get any updates). If you flash a ROM you will indeed loose everything, including Touchwiz, but if you backup your personal data then loosing Touchwiz could be a good thing, at least it was for me. I prefer Cyanogenmod.

Yes. You can use clockwork mod (cwm) to backup everything. Its recommended to take your backup using cwm before flashing a custom Rom. So that whenever you want your stock back or something with your new rom goes wrong you can revert back. You can use cwm to restore or use Odin which will make your device like when you bought it. You can restore the data alone using advance restore and your device will be like before flashing custom rom.

i guess, if smth goes bad during rooting i cannot revert back. since for backup one needs to root the device beforehand. is this right?

I dont think cwm needs root access to take a backup. And you can rely on odin always if you got stock rom. So something goes wrong, Odin to the rescue.. So try taking backup with cwm first then root. Anyway if the root update was made for your device then its very very rare for things to go wrong.

[ROM] Tab 3 7.0 SM-T210/R Stock 4.4.2 KitKat Update

This is the stock US KitKat ROM for The Galaxy Tab 3 7" Tablet. Finally found it after a bunch of hassle online, and figured I'd post it here to make things easier for everyone.
When I Odin'd this ROM, it actually upgraded my tablet, and left all my items installed (not guaranteeing this will work the same for everyone else).
Afterwards, I just Odin'd TWRP to reroot using Chainfire's SuperSU (no other Superuser would work) and called it good.
Caution: if you are using a custom ROM, this may not work without reflashing stock 4.1.2 since the 4.4.2 ROM appears to be an update, rather than a full ROM.
Rooted devices and custom kernels that are otherwise stock should be fine.
The cache, and if possible dalvik-cache should be cleared before flashing. Some of those files can sometimes interfere with upgrades.
It might be necessary to pinpoint apps that are force closing, uninstall and reinstall them. Some apps, particularly paid apps, store their data differently on KitKat, and will automatically fail as a result.
If that fails, it might be necessary to factory reset the device.
The Stock 4.1.2 ROM for the T210R is available here: http://forum.xda-developers.com/gal...-stock-sm-t210r-4-1-2-jellybean-odin-t2958676
The T210R...XAR file is for the 210R:
https://drive.google.com/open?id=0B2iEgzRTFjrQTmI0ZjRBbWtOajQ&authuser=0
The ITV file is for the T210 (no R)
To download these ROMs, a torrent client is required (such as utorrent).
Anyone who wishes to contribute, please seed if you can after downloading ("Force Starting" the torrent will seed it indefinitely.)

I've seen both devices referenced together quite regularly, implying that they use the same ROM.
http://www.boeboer.com/samsung-galaxy-tab-3-7-sm-t210r-manual-guide-wifi/
And even use the same kernel from what I've read:
http://forum.xda-developers.com/showthread.php?t=2439564
I would take standard precautions, such as having a odin image of your original software available and performing a backup of your current system (if able).
Perhaps someone else has some insight to this question?
edit: Looks like I had my information wrong. Found where I obtained the ROM from, it is for the T210R model, and was not intended for the T210.
There are custom ROMs that have been patched for use on both devices, which is where my confusion came from, but this is an official ROM.
I have gotten my hands on the T210(no R) ROM file, and have update the Links above.
I am not responsible for any failed attempts at flashing to either device.

First, thanks for this. I have the T210R. I tried using this and had the same result, it updated the tablet instead of loading a completely new version. I did however run into a problem...the tablet had many for closes and reboots to a point it was unusable and so I reverted back to my backup. Did you see this? Maybe I had a bad download?

I did not have this problem, but I didn't have much on my Tab either. (Some apps don't play well with KitKat upgrades.)
Torrents have multiple segmented hashchecks to make sure you get an uncorrupted download, but it might still be possible. I'm reasonably sure my file is OK since I've used it (can't speak for the non R file though).
Did you clear your cache, and if possible your dalvik cache? I've read that some of those files interfere with upgrades.
If you can pinpoint the apps that are force closing, uninstall and reinstall them. Some apps, particularly paid apps, store their data differently on KitKat, and will automatically fail as a result.
Other option would be to try a factory reset and see if that fixes it. (I understand not wanting to do that though.)
One more thing, if your ROM isn't stock, or stock rooted (custom kernel should be ok too), you may have to flash 4.2 before the 4.4 ROM will work on the device.
Right guys, here i go, just joined and first question!!!
i have not ever rooted a sm-t210 but it was rooted when i bought it second hand!
i have linux installed on my p.c. and was wondering if there is a way to upgrade to and official KITKAT!
as stated i am having problems because my SM-T210 wifi only! and want to update to kitkat official release!
but was hoping also that there is a way/method to root via LINX and not via windows!!
if that is not possible how do i go about it on windows!! as i can use a friends WINDOWS-P.C. if i must!
ah also my SM-T210 does not have the options to change the function of the USB-function,,,
i.e.
it used to have an option to,, use as a mass storege, media transfer or use with samsung keis,,, or some thing of the sort
but this option has dissapeared! may have been my fault!!!! as i uninstalled some system apps,
now it crashes and reboots whenever i try to turn of USB-DEBUGGING options in DEVELOPER-OPTIONS !!!!
many thanks in advance,

Just to triple check, by the above quote you mean that if my tablet is currently rooted, I should still be fine to flash this update correct? [obviously it would become non-rooted once flashed and I'd have to re-root it as you mentioned you rooted after installing]
Also, how much space does this take up?
thanks

That is correct. I was rooted running the Werewolf custom OC kernel. I still had my tablet upgrade without wiping, and one other user has reported back saying the same. But I can not promise upgrade as opposed to overwrite.
The flash file once extracted, is about 1.4 GB, I don't know sizes beyond that. It does not repartition the tablet however.

Could you upload the T210 ITV file? This torrent is going to take 10 hours
No system file
Well this is awesome, system won't mount and I don't have a backup. Samsung website does NOT have the stock firmware, and attempting to get it for another country just to get this to load so I can flash a ROM leaves me with having to download at 15kbs. I am in the process of selling this to someone for their kid... And there are ZERO seeders for these files. Lovely.

For some (unknown) reason, Odin3 nor JOdin3 doesn't seem to work for flashing my Samsung Galaxy Tab3 device. For that reason I tried Heimdall-Frontend, but to make that work you need to extract the content of a stock ROM first.
Anyways, it still didn't lead to get my device into factory reset yet.
But that's another story on which I still have not yet found the answers needed to get the device successfully back into factory reset.
My guess is that the 'system.img' file, of Android 4.4.2, successfully has been loaded from Heimdall-Frontend, yet by going into reboot right away after Heimdall-Frontend releases the connected device, the download may be deleted.
I read that the cause of that may lie in the fact that Android 4.4.2 is only an update and no full ROM.

D801 TWRP Issue - Bottom portion of touch screen doesn't respond

tl;dr - TWRP touch screen won't work after installing custom ROM, much hassle to unbrick, looking for a "bumped" (still not actually sure what that term means) or otherwise modified version of TWRP that won't go haywire when installing a custom ROM.
tl;dr 2 - Also interested in the LATEST "stock-based" ROM recommendations anyone may have... G3 backports or whatever. She needs her Camera to work well but older 4.4.x and 5.0.x OS is missing a lot of new functionality and compatibility with new apps.
I'll just start out by saying that I've figured out just about every way to brick and subsequently un-brick this device that is feasibly possible, and am considering starting a thread specific to those various methods... but that's not what this is for.
This is an issue I've encountered a few times now, definitely on my girlfriend's T-Mobile LG G2 D801 with Lollipop (30B and now again on D801 30C), and iirc, also on KitKat.
I'll explain what I can remember, most of this has been done in the middle of the night after many frustrating hours of attempting various methods... I have to say, this phone has been much more difficult to mod compared to my previous experiences with Samsung and Nexus devices.
I had gotten this device all the way through to CM12 or 13 a year or so ago but recent issues made us decide to attempt to revert back to a Stock-based ROM.
Steps:
1. Root (ioroot / Autorec, can't remember which or for what reason, I have multiple versions of each)
2. Install TWRP Custom Recovery (most recently and successfully using a modified version of the "30B Freedom Tool", although I haven't tried that on 30C - yet.
3. Transfer custom ROM & Kernel to SDCard.
4. Boot into TWRP and install custom ROM & Kernel - most recently GoogleEdition 1.5 and then DorimanX 12.0 Kernel
5. Clear Cache / DALVIK Cache.
6. Reboot device. This is where the trouble begins...
Results: Won't boot into OS at all, instead I end up at the text-based "fastboot" screen, which after multiple tries I can eventually get back into TWRP or into Download Mode.
Once in TWRP after installing custom ROM, the bottom ~1" of the screen won't respond and all other touches aren't accurate... playing with it, I can usually eventually get into some of the TWRP screens, but for most purposes it's about useless.
I managed to restore a backup of the original 30B system image via command line over MTP using ADP TWRP commands, but that bricked the phone in an entirely separate manner where I couldn't access Recovery anymore and the system wouldn't boot at all... I ended up using the LG Update tool to get it up to 30C, and was surprised to find that it still had the restored backup data (apps, pictures, settings, etc), and the phone is now working again, albeit back to stock recovery.
Now, as I mentioned, this isn't the first time I've run into this "phantom touch" issue in TWRP on this device, although the circumstances seem to be a little backwards this time vs when I was taking the device over to CM12/13. I think I remember something about a "bumped" or otherwise modified version of TWRP being out there, but I can't find it now or put my finger on what the changes were.
Has anyone else run into this? I am hoping I've just overlooked something, but days of digging through threads hasn't turned up much.
/edit/ To give you an idea, attached is the folder I've got files stored in... with tons more in Archive and Stock-Based... I've used them ALL at some point. I'd like to get enough info in here to write a Step by Step guide for new owners who are picking these devices up on the cheap, and would appreciate if anyone wants to help out with this!

What is missing for nandroid backups/"normal" flashing process?

I know we don't have a complete implementation of recoveries, like twrp/of (I know it's basically the same), yet. But now that we have the kernel source, what is still missing (vendor?)?
Also and kinda of a similar question, what is still missing regarding a "normal" flashing process? Like wipe system, data, dalvik/art, cache, flash rom and not having to have a base stock firmware and needing to format data.
To be honest, I'm a bit confused with this phone. My other phones (admittedly last one's didn't get past Android 9), were so different in that regard.
So I'd really appreciate if someone could take the time to shed some light on this.
Maybe we'll see a stable version of twrp for surya but support for dynamic partitions will not be available soon.
Having to format data everytime you flash a new rom may be solved having the kernel source. I think it has to do with encryption keys. Even if you don't have any password set in the OS, miui still generates keys to encrypt the data and when you wipe only, they get deleted hence, data on the internal nemeory remains encrypted. That's what I think.
https://twrp.me/site/update/2019/10/23/twrp-and-android-10.html
Ok, to be honest and judging by the fact that the announcement by Dees_Troy was over a year ago, things look pretty difficult to say the least.
I had my last phone (axon7) for so long that all the new implementations, like dynamic linking and super partition, weren't really on my radar.
Guess I was a little naive in thinking that the kernel source would be of any help in that regard.
This lack of stable time-tested solutions worries me, too.
That's the main reason why I'm still on stock ROM on the Poco and the Axon 7 is still my daily driver.

How about EU ROM ?
Thanks for your thread.
I'm asking too.
I went from an old device too (redmi note 4 mido), and i'm a bit lost on flashing process.
Is it possible to :
Install orangefox via fastboot.
Wipe all & format data.
Flash recommend firmware for rom.
Flash custom rom.
Flash gapps.
And boot ?
Any problem with that ? What i'm missing ?
Don't have phone now, I'm waiting for shipping, and will wait for unlock bootloader access. I hope it will more clear and simple when I will discover poco x3.
You can do all those things. What you can't do for example is make a backup and restore your current custom rom.
Oh ok.
Sorry, miss understood your op post.
I was confused because on some custom roms thread, I find strange install instructions, like : dont wipe anything, format data AFTER flash custom roms...
Somes roms requires frimware 12.0.3. What about if phone have a more recent ? Can I downgrade just by flash fw+vendor on recovery before flash rom ?
And some people said they have bricked there devices.
Just to be sure to don't make stupid error on fresh new device, that I can't solve with miflash and fastboot.
Thank you for your reply.
I only clean flash roms, never backup, don't have a lot of apps, and majority have import/export options in-app.
But I hope for you it will be fixed soon.
