from havoc (pie) to xiaomi.eu (nougat) - Xiaomi Redmi Note 4 Questions & Answers

Hello, I gave my "old" mido to my mother running havoc os. Everything is running fine, but the call quality is really bad. I would like to switch from havoc to xiaomi.eu.
Is there anything special to consider, or just wipe system , data, cache and dalvik and install zip from Internal storage? Thx for helping me.

Clear the internal with f2fs and wipe the data via TWRP. Wipe completely all partitions including system, cache, data, dalvik, vendor, firmware etc and flash the ROM. Do not flash Magisk or any other root solution and everything should be fine.

F2FS. Affirmative.

Flash Oreo rom (max R30), to convert your data partition into the old one.
After that, just flash any rom you want

[Q] What does wiping system do?

Im sorry if this is such a nooby question but on some custom roms it recommends to wipe /system. What does this do? And what do you lose? When I usually go to another rom I wipe user data, cache, dalvik cache and battery stats. I never had any problems by doing so. In my case I never saw where to wipe /system I found out it was under mounts and storage in recovery a few days ago.

This is wrong....
The /system partiton is where Android itself gets stored. As in the system apps and framework. It is recommened to wipe it when changing to a *non-wipe* firmware just in case some files are different and get left over from the previous rom.

Thanks, that makes sense.
not wiping before installing a new rom usually results to bootloops.
i see to it i wipe before installing another rom (unless i'm installing a newer version of the existing rom)

As was posted earlier in the thread, wiping system basically wipes the rom/os and system settings. Your user data, apps, pictures will not be wiped. If you rebooted after wiping system the phone will not work, however you could wipe system then flash an update of the same rom and reboot and you should be fine(depending on the changes between rom versions). This is basically referred to as dirty flashing. FYI, most custom roms have a script which wipes system, cache and dalvik/art cache automatically preserving only /data(user apps and data)

[Q] Just got a Galaxy S2 today - Question about Wipes in Clockworkmod

I've had a ZTE Blade for a year and whenever I flashed a new rom, i'd boot into clockwork and wipe dalvik, battery stats in the advanced tab.
then i'd go to mounts and storage and wipe /system, /data, /cache and /boot followed by data/factory reset and cache in the main menu to make sure the system was completely minty fresh before i flashed.
just looking at clockworkmod for the S2 and i was wondering if there's a similarly recommended set of wipes ?
as far as i can see, it appears to be Wipe Data and Factory Reset, Wipe Cache and install - is that really it or would it help to do the /system, /data and /cache in the mounts and storage menu as well ?
thanks in advance
Wipe /system, /data /cache and dalvik cache. That should be enough (what I've been doing since april )

Thanks. I've just flashed the resurrection remix rom and only wiped dalvik, data/factory and cache and everything seems to have installed fine and is running ok so far - probably because i came from the stock ICS rom i suppose.
i'll remember that in the future though, thanks

Hi, this is my 1st post but have been flashing almost daily for around 4 months. Ok so here's my uber anal method
Wipe data/reset. (x3)
Wipe cache
Wipe dalvik cache/battery stats
Format cache/system/data
Flash rom
(if dual booting flash kernel cleaning script then flash compatible kernel)
Reboot/set phone up Google accounts etc/Reboot. Then wait at least 5 mins for rom to settle. Enjoy!
This imo is a full wipe which I use regardless of whatever rom I'm flashing. I know some installs you can get away without full wipes but for peace of mind I use this method. It can be a pain setting up a fresh install but with using TB & launcher restores it can be done in less than 20 minutes. Good luck

Question about Jokersax's full wipe zip

I assume the advantage of using the full wipe zip is how fast it works. What else is recommended to wipe before flashing a new rom. What I have been doing is flashing the wipe zip, then formatting system, cache, and data, then wiping dalvik cache. Is all that necessary? Should I also be doing a full wipe/ factory reset? Thanks in advance.

I believe the zip you are referring to is Bills fullwipe zip. It wipes everything needed to flash a rom except dalvik cache. So, flash the zip, wipe dalvik, flash your rom.

Yes, sorry, its Th3Bill's zip, but I got it on Joker's site. So its normal for it to wipe superfast, like in a few seconds? What about formatting system, data, and cache, is that not needed either?

Nope, that's the three it wipes. And yes a few seconds is normal. Only thing you might wanna wipe is dalvik.
But, I mean there is the full wipe/factory reset, and then under mounts u can manually format each one. What is the difference between formatting and wiping?

For our usage, not much difference.. But technically, wiping referrs to 'deleting' everything there. Deleting makes something disappear, but doesn't make it nonexistent. It just tells the system that this space can be used for other things now. Until the the given sectors where the data resided are used to write something else, the deleted items technically still exist. Formatting, on the other hand, goes through every sector and writes over it with 'blank' data, securely making the data unrecoverable (for the most part).
How can you relate this to your phone? Well, if you are installing a new rom, wiping the data is sufficient. If you are getting rid of your phone for whatever reason, formatting is suggested.
Ok, thank u for the clear explanation.

Pie Vendor just means the vendor files which is the modem and baseband etc. It just means that it is the version that is compatable with pie based ROM's. Pie is the codename for android 9, most ROM's and the latest MIUI are pie based.
If you are just updating your pie vendor firmware, you do not need to wipe your internal storage.
If you mean that you want to upgrade/change ROM's, it is best to wipe data, cache, dalvik and system before flashing a new ROM. If you are just flashing a newer version of the same ROM, you can just wipe cache and dalvik and you should be okay to flash.
You only have to wipe internal storage when unlocking the bootloader, its an automatic thing.
Hope this helps!

Android Q ROMs TWRP fails to map file

Hey guys,
I already have done hours of research and I have been trying and failing a lot of times. So here´s my problem. I wanted to flash a new Rom , the newest MSM Extended and the newest Pixel experience. I´m on Twrp 3.2.3-2 and on the newest firmware for the Pocophone (V11.0.5.0.PEJMIXM). Everytime I try to flash the ROM it says "Error 7" for Msm extended and "failed to map file" for Pixel Experience. I already tried all versions of Twrp for Poco F1 and I tried a 3.0.1 vesion of another device but the TWRP simply didn´t work. I always had to flash my old msm Rom which is always working. I think it´s because of the Android Q update. But I already have the latest firmware so I really don't know anymore.
Try latest twrp

Does that change anything? It's the internal storage right? I always wipe Data Cache Dalvik Cache and System Data.

When you get from pie to q, you have to format your storage. It's not only wiping your internal, it's a different option in twrp.
Format your storage, reboot into recovery and then it will work.
Mind that you you have to format again and do some other things too if you decide to get back to pie afterwards.

Alright. So I just have to find the option to format my phone? Doesn't that also wipe my internal?The zips for ROM, GApps etc. are there. Is it possible to transfer files while in Recovery? If yes then I can follow. I don't quite understand right now. Sorry for the late reply. I was busy with school.

The button for formatting is next to "advanced" in the wipe menu of twrp.
It will erase everything, yes.
You have to transfer the zips needed from a pc/microsd/usb otg to your storage once it's been formatted while being in twrp.
So I'll have to Advance Wipe>Internal Storage, Dalvik, Cache, Data. Then Magisk will flash easily?
I'm using the POCO X3 right now running MIUI 12.
