How do I completely restore everything to stock? - Xiaomi Redmi 4X Questions & Answers

First of all, I know that this question has been asked before but the solutions on those threads aren't what I'm looking. So please hear me out here.
So, I've been trying to find out how to completely restore my phone to stock. People said to flash the fastboot rom and I did but it didn't restore the phone *completely*. First I thought that it did, since the custom recovery was gone along with the custom rom. But then I flashed twrp again and I noticed that my previous twrp settings and theme are still intact, meaning that they were not wiped by the fastboot rom.
What should I do to remove them completely? On Samsung phones i could just flash through odin and everything would be restored. How do I do it on xiaomi's? Thanks!

Did you choose clean flashed and lock option? or flashed with save user data? choose clean flash and lock (it will wipe everything in your device so do backup first).

Flash the latest miui stable version

yes i tried that, then i unlock the bootloader again just to make sure, flash twrp and yup my twrp settings are there still. if it were wiped it would have reset to default settings right?

It should have made clean flash. honestly i never cared about after clean flash if it retains setting or not because that doesn't even matter at all to me since i am using android or caused any problem /issue.
May i know what is your purpose of getting rid of TWRP settings? and what exactly setting you want to get rid of?
if still care about getting rid of full twrp setting i highly recommend you to visit xiaomi service center and ask them to install latest version because they thoroughly clean flash device like it was out of the box using some other method.

[Q] Flash stock ROM by Odin dont erase all user data?

I was surprised that after flashing stock ROM by ODIN, phone was not cleaned from the user data.
I mean: account settings, applications installed by user, etc.
I know that flashing dont erase data from internal/external SD card, but why all data was still exist?
Only Wipe Data / Factory Reset will erase all user data?
Btw, Merry Xmas

Nope, factory reset will not erase all user data. Go into setting/storage and delete from there (not sure cause I didn't have the device now). If you want to erase using odin, tick the repartition box while flashing the firmware. This is the easiest way I think.
Odin flash doesn't wipe user apps and their data, but it may cause bugs if you come from another ROM...
E.g : if u soft bricked on stock JB, just odin flash is necessary.
for other ROMs, it may or may not lag.
I will describe my way.
I tried to install CM 10.2
I did factory reset, next steps follow procedure.
When I did first start, unfortunately keyboard stop working, so my cyjanogen install failed and I decided back to old system using backup.
After restore and start, phone required settings like on first start after factory reset.
Lol, big surprise.
Ok, I entered necessary information but after reset -
again same like after factory reset
I tried from another backup with same result.
Hmm, big mess.
So I flash stock ROM by Odin.
And new surprise - phone with fresh system and all my own settings and applications from last restore.
Two disappointments:
1. Restore from backup does not cause a return to the initial state.
2. Flash ROM by Odin don't make factory state of phone.
I have question, if format partitions: system and data and next restore backup will do real state phone on this backup?

1. Almost every restore from backup for me it returned phone on state when backup was made. Only if my backup was bad (did not have enough place on sd for backup or something corrupted it).
2. Flashing stock ROM by Odin do not touch data partition (or folder whatever it is). So if you want to erase that, you need to make factory reset. It is like that on every Samsung Android device - I am not sure for other, never used.
When you come back from any CM10.2, Omni 4.3 and CM11 based ROM - first flash stock with Odin, do factory reset - and after that restore backup (ofcourse first root, install CoCore kernel for CWM before restore - you can't use restore in stock recovery).
Tnx for answers.
This is weird that format system partition not enough to get rid of the CM
But I checked this again and exactly after refresh ROM by Odin - restore my settings and data works fine.
Hmm imo this is mess in whole Android system

Explanation for that, TeamJanica used preload partition for swap, and it is patitioned in other format than the one stock ROM use. That partition is not used on CM for files, but it has it's use on stock based ROM.

supposedly you have downloaded the stock FW, flash via Odin with re-partition ticked. if it fails, extract the PIT file from CSC_OMC_OXM_XXX save it in a location and load it at the pit session via Odin the re-flash again with re-partition ticked.

New to flashing custom rom

So I've rooted, unlock bootloader but still encrypted on my nexus 6. So far I went with Franco kernel & ViperAudio that's about it and I'm enjoying it.
I'm wanting to flash a custom ROM very soon and I'm new to this. Ive made backups thru twrp with nandroid already.So please bare with me.
Questions
Do I have to be decrypted before flashing a ROM?
Can I load viperaudo.zip & Franco kernel.zip along with Custom ROM, Gapps & SuperSU at the same time on Twrp?
From videos I've seen people just wipe on twrp and then install the ROM, is this a safe? Or is it better to a full factory wipe.
After flashing a ROM, will my old files still be there like pictures ive taken, stuff that I download & will my old apps be there still.
Thank you in advance.
1. its your choice, to stay encrypted or to decrypt. im still encrypted and running terminus rom
2. yes. but tge rom will always be the first flash, since itll overwrite anything you flash before it.
3. i normally dirty flash, meaning i dint wipe a single thing when flashing. that way i lose nothing. but, i always have a nandroid backup, just in case.
4. first off, your storage never gets touched, unless you wipe it yourself. if you dirty flash, you lose nothing. if you clean flash, you factory reset the phone and need to reinstall your apps, through backup of somekind or manually.

So flash the ROM, gapps and super su as the thread of the ROM says and then use the ROM for a bit and then twrp and flash ViperAudio and kernel...
So if I lose nothing do I need to reinstall the apps...
Thanks for the response

id flash viper and your kernel at the same time, with the rim, gapps, abd supersu. if you dirty flash, you lose nothing. all you do is update what you already have. your apps stay. buts thats only during a "dirty" flash

So for my case, stock and rooted and to install this ROM what are the primarily steps instead of dirty flashing. I wanna do everything from the phone.
Sorry for being a noob. I know if I fuxk up anything I can always revert to my nandroid backup.

[Q] Twrp flashing order check?

I'm trying to flash chroma rom onto phone with leankernel/hells core and verizon 5.1 radio. May someone confirm this is the correct order? I'm currently on latest chroma with franco kernel. (i don't like dirty flashing )
1. Wipe everything but internal sd
2. Flash latest chroma
3. Flash latest leankernel/hellscore
4. Flash Gapps
5. Flash verizon radio 5.1
Should i also include Supersu in the steps?
Also, if my internal memory is getting a bit cluttered from apps and other random stuff, is there a way I can reset my phone to a rooted, bootloader unlocked, unencrypted state without doing a full reset to stock then doing everything over?

first off, why would you have to go back to stock???
secondly, the radio can be flashed at any time, no order involved in that.
thirdly, when you wipe data(everything but the SD storage), thats a factory reset. so, wipe data/system, flash chroma, flash the gapps, flash SuperSU(for root), then flash your kernel and reboot.
As long as you flash ROM first, doesn't matter about the order

Sorry, a clean sd card is simply one of those weird things I like(It might be ocd or something xD). When i had my s4, i would do a full reset to stock every time I flashed a rom because I didn't want any residual files left over. That being said, is there any simpler process to reset or clean the internal memory between flashing roms besides stock reset? What I'm talking about is some way to set or "reset" the nexus 6 to a unlocked, rooted, unencrypted, and twrped state but otherwise stock.

Make a backup in TWRP of your device when it's in that state. Then flash that backup whenever you want to return to that state.

just do a full wipe in twrp, itll clean out your storage. but move all the files that you want to save to your computer or they will be gone.

After I full wipe, I can use mtp to transfer the rom and gapps in twrp right? Or do I have to use adb ?

Does flashing stock ROM via Odin wipe data?

Hello,
So my Galaxy S6 is stuck in a boot loop and i've literally tried EVERYTHING already and nothing will solve the problem. Safe mode won't work, clearing the cache partition won't work and USB Debugging was turned off so adb wasn't seeing my device either. I also tried Kies and Smart Switch. I am convinced my phone is soft bricked and I need to recover some very important pictures and files from it. At this point my last hope is to flash the stock ROM via Odin and I saw that some people said that they have successfully done this without losing any of their data. Is this possible? If so how do I go about doing it properly?
Thanks for any help!
Phone is not rooted and 100% stock.
Recovery and Download screens are working.
How did Kies not work for you? I used it about 4 times to restore to like new.

Because the phone is stuck in a boot loop. Kies won't detect my phone because it never fully boots.
Weird. I completely removed the system on one before reinstalling the system via Kies before sending it back via warranty exchange. I'd suggest trying again. Obviously you will need model and serial #.

Tried Kies multiple times but it just won't work. Uninstalled and reinstalled drivers, disconnected and reconnected the phone, nothing works. That's why I turned to Odin.

Since you can get into recovery, if I were you I'd flash Unikernel (latest version is 9.1 I believe) and then flash a custom rom. If you can get it to boot you shouldn't lose data in the sdcard/download.

Forgot to mention but I am going to have to return this phone to T-mobile for a warranty exchange, that's why I was trying to avoid custom rom's thinking it might become ineligible. Want to be able to recover data and then reset the phone for return
The phone i wiped the system on was returned via warranty with Tmobile (of course I later reinstalled it via Kies). I would install a custom rom to attempt to get the thing up and running. Once you do that then go from there (back to Kies or factory reset...)

Ok, Thank you! I was worried about the warranty exchange. I will attempt to install a custom rom let's see how it goes.
The purpose of installing the custom rom is to attempt to retrieve your data. If you can boot and then successfully get your data, it would be advisable to remove the custom rom and restore it to factory. Let me know how it goes...

If you've got recovery installed it would be just for that purpose. Restoring your backup (i.e., recovery). I gather you don't have a backup?
What device do you have?
G920F International. The Recovery is not a custom one . It is the default recovery that doesn't have backup mode.

Ahh gotcha. Well...if it were me what I'd do is to boot to download mode and flash TWRP custom recovery file using Odin. Once that passes I'd boot into TWRP and do a backup.
You can then reboot into TWRP and try to restore your backup but you'll likely end up in a bootloop again. If that happens...
Then, I'd download a stock recovery (looks like they have your variant here.
I'd then flash the stock recovery using TWRP and then reboot.
If you get stuck in a bootloop again then I would do a factory reset (which doesn't wipe storage which is where your photos etc. are) and then reflash the stock recovery zip file.
I can't say for certain if that'll wipe your photos, etc. or not but I'm not inclined to think it would.

Will factory reset/wipedata from stock recovery remove the pictures ?
Can you backup data using OTG/pendrive from TWRP recovery?

factory reset doesn't erase storage data.
Not sure about otg/pendrive
Sent from my SM-G920T using XDA-Developers mobile app
I didn't flash TWRP as I learned that Samsung Pay will never work not even Stock ROM flash. I instead pulled some vital data files from adb pull on 'the window of around 1 minute' each time it was active during safe mode rebooting and thankfully Google Photos had a backup of my Photos and videos.
I used the wipe data option on stock recovery that wiped everything. The device is like new.

HELP - i flashed the EU rom and wiped Dalvik cache, and reeboted, now It reboots to the TWRP over and over again, what do I need to do?
You also need to wipe data and such before flashing, so maybe you didn't notice or forgot, but as long as you have TWRP, you can recover.
Maybe your ROM download got corrupted. If possible, check the checksum, they should provide it.
It's also possible your USB port + cable combo doesn't work properly, it's happened to many people, so if you are sure it's not the rest, it might be just that

I flashed it but now every app I open crushes, Im on weekly version and I restored apps from the Xaiomi backup, do you know why?
I can't say I do, but I'd assume it's because Xiaomi backup is configured to work only on stock roms.
It's possible that uninstalling and reinstalling each app using whatever the proper app shop is for the given app will fix it without losing the restored data and cache for it.

I would always assume auto backup things to fail when you need them.
Try to reflash your original rom from here and restore using the same backup tool: https://forum.xda-developers.com/t/miui-updates-tracker-mi-11-pro-ultra-star-mars.4263135/
Then you can reevaluate how you wanna backup and restore to transition.
It's possible it failed because you have an official rom backup, but it would work if the tool had backed up from Eu to Eu

I will just Factory reset and reinstall manually..
To factory reset in brings me to TWRP, why is it?
Because you installed TWRP instead of the normal recovery utility, you now have TRWP in that partition on your phone. If you use TWRP to flash the proper stock ROM, it will have the same effect as using factory reset using the stock recovery utility. BTW, the stock recovery utility is not built to support having flashed another rom, so you're in good hands having TWRP instead.
You probably had issues because you only wiped dalvik rather than format data after installing the EU ROM. You must format data after flash because the different branches have different partition layouts, hence your problems.
As you must format, you might as well start from scratch again or go in to twrp wipe menu and select format, type yes to confirm and then reboot system. If you want to go down the full install, then flash the ROM again, format data, with the yes confirmation, then reboot system. After each update, just a dalvik wipe is
