Bad performance/Slow device - Xiaomi Redmi Note 3 Questions & Answers

Bad performance/Slow device - Xiaomi Redmi Note 3 Questions & Answers

I know this kind of thread has been already asked but I am having serious problems with my RN3Pro (2 Gigs, 16 ROM) since years (since 2017), its laggy, slow, and no matter what ROM I try (I tested SMIUI, Cyanogenmod, Lineage, Resurrection Remix, Liquid Remix, CRDroid, AOSP Extended ...) ... I even installed Radon Kernel to try and improve the system performance, nothing helped, enabled zram too, still the same.
I usually run between 2GB/200MB of internal memory free, due to telegram cache and all these things, still the same, no matter what I do, its slow in all senses.
When I install a rom I do a total wipe with new openGapps and new magisk, I never dirty flash over nothing, the phone can run fine but as soon as I install my apps (or I restore them by titanium backup) I go back to slow performance.
What I should do ? Im actually on Pie (AOSP Extended, no Radon Kernel), but im planning to go back to Oreo (AOSP Extended, Radon Kernel installed) or come back to MIUI
Im afraid of come back to MIUI since I love to touch my DPI settings, I use Adaway, Kernel Auditor and a lot of things I cant do with MIUI.
May someone help me ?
Thanks.

lol :laugh: your answers lies in your question itself.
Noone face problem. Why? Think first.
What u doThats not Clean flash.
Make sure u r on latest official twrp 3.2.3
First go to twrp . Format data to decrypt data and erase internal sd.
Go to wipe. Press format data
Type YES to format
It will erase data and internal sd partition.
Then Wipe data reset.
Flash rom
Flash gapps
Reboot
Do not restore any data backup from twrp.
When u first boot into system. During initial setup wizard. select DONT COPY DATA. Start as fresh setup.
After setup finished.
Do not restore backup or anything from titaniuim backup. Its main cause of ur problems. Restoring old backup on new android os bring crshes, bugs, drains, laggs.
Download and install everything from playstore.
Its done .Now check ur performance.:good:

Thanks, I'll keep that in mind then, since I faced all these problems for a lot of time didnt knew maybe titanium backup was a possible reason, I do backups of my apps since 2014 and never had problems on any other device ...

Thanks again

Days ago, after read you, I decided to give up and go back to MIUI and then start again, with a total erase and full memory reset, I updated TWRP and also installed all with only a few titanium backups restore (I needed them, so I had no choice), the phone now runs quite aceptable and great, I took a look at kernel auditor before and after the complete restore, before I wasn't having any deep sleep, now, my phone have deep sleep most of the time and less high freq's
Didnt knew that titanium backup and not formatting my personal data was too bad, thanks again Black_Stark!

Recovery tweaks

Just an idea to restore large data.
An idea is coming to my mind where we can use recovery instead of titanium backup to restore large amount of data.
The idea is to backup only data, android.secure folder and ext via amonRa recovery.
Now, if you are changing roms, you can try to do this thing.
After installation of the rom, restore this backup via recovery.
(If you have ext, flash dt apps2sd first and then restore.)
Don't wipe anything after restore and reboot.
See how it goes.
If all goes well, this may be a good alternative to titanium where a whole bunch of data is required to be restored.
I will also attempt this shortly.
Another important thing.
Just two hours back I flashed cm 6.6.1, flashed gapps, flashed Franco kernel 40, flashed dt apps2sd in that order without rebooting and everything went well after first reboot. I had rom, gapps, kernel and ext everything working fine. So I think there is no need to reboot in between in this case.

Nice trick, but you can only restore all apps or none. You cant select which apps you would like to restore and if any of the data gets corrupt you will lose all apps.
Hows 6.6.1 treating you ? I am using 6.5.7 which is great in terms of performance and battery.

Often, while changing roms, we think of having our current apps on the new rom.
As for 6.6.1, its going very fine. Previously I had uninstalled it due to wifi problem, but I hadn't checked it with Franco kernel.
With Franco gb kernel its all fine.

Did you try with app2sd script ?
I've once tried this but with data2sd, it didn't work. (or maybe the script doesnt succeeded at first place).
Anyway, thanks for reminding this

i believe this may also work with cwm (make a backup, wipe the usual stuff, flash the new rom, restore data.img in advanced restore). please confirm this

I think it should work. We will have to select all three data/android secure /ext one by one.
Sent from my LG-P500 using Tapatalk

It works!
Just used this method to upgrade from mike's os beta6.5.6 to beta6.5.8 with Darktremor's A2SD.
-Booted in the cwm recovery and did a compleat backup
-Wiped everything, data/cache/dalvkin..everything
-Flashed os (didny reboot as recomended)
-Flashed new kernel
-Rebooted to check if the OS was loading (think you can skip this)
-Back to custom recovery-> backup and restore -> advance restore -> restor data and sd-ext
-Rebooted to check if the os was loading (think you can skip this)
-Back to custom recovery -> flash darktremor 2.7.5.3 Beta 04 reboot (realy took long 5min+ to load)
Tryd this a couple of times ( hence the many reboots to check if everything was ok) at the end didnt manage to make it boot with darktremor's 2.7.5.2-1 had to go with the relative new beta.
just my 2cents

Yes it works fine - with Advanced Restore
Hello,
To Switch ROMS
I have tried this twice - 1st do a nandroid backup
Wipe data/ Factory reset/ wipe cahe/ Dalvik Cache
Flash new ROM - Reboot for assurance really
Advanced Restore/choose backup/ restore data then restore cache/ reboot X 2
I find this easier than Ti Backup/ and more comprehensive.
I do not recommend ROM Manager for anything other than flashing recoveries
Thanks for reading this far

Info on Cyanogenmod Updates

I'm currently running a cm 12.1 official nightly that's about a month old on my XT1022 and it says that cm 13 (nightly) is finally available for my phone as an update......
When I install this update, do I lose all my data and start over? All the stock cm12.1 apps that i deleted or replaced, do they return? Also i'm running TK Gapps (the latest release), so do I need to reflash it after installation? My recovery is TWRP (The latest version). Will I have to root again?

System update won't cause data loss but a nandroid backup is always recommended.
Stock apps of cm12.1 won't come but the stock apps of cm13 (this might include common apps like browser or file manager).
Yes you have to flash gapps again. You may not have to root again coz supersu comes with a backup script. (this applies to gapps too, some comes with backup script. So to be safe flash gapps again just in case)

Would I have to flash my custom Kernel (Zapdos) again? Also, What about the apps that Iconverted to system apps?

Yes you have to flash your custom kernel again after updating.
Those apps will be removed you have to download them again and make them system app.
Do one thing, the apps you moved to system, convert them back to user apps and then do a nandroid backup.
This because when you'll update rom data of those apps might remain and conflict when you'll download them again.

When I realized the update on my phone ... the apricativos part were , but I ended up doing a clean . I thought it would appear the option to restore a backup of Moto And normally the Google saves the information , but Will not appeared.

Yes, but in the previous ROMs same to make a clean completely, the time that appears the first screens to set up your machine ... provided the option to restore the latest handset by Google settings.

You should always clean flash major updates like from cm13 to cm14.1
Dirty flash always leads to problems

Try titanium backup and backup the necessary apps
And then clean flash LineageOS 14.1 then install the necessary apps from playstore and restore only the app data using titanium backup
Note:- I can't guarantee about your data but you can try this (at your own risk) method it might help
& I haven't used this method i always clean flash after taking necessary backups

Can you or someone tell me the steps?
I have done it before, but i forgot how to... already have de titanium, but im afraid to start the procedure because if i do this titanium backup it will go to the internal storage and when i flash everything i will lost it.
I dont remenber the properly steps.

I have clean flashed cm 14.1, it is a disaster . Most of the apps stopped working and also system webview keep crashing. I want to flash back Cm13 most recent version but couldn't find it anywhere on web or cm website. What should i do ? Could anyone provide me a link to cm13 most updated nightly ?

Actually I never used that because i just take backup of data in internal storage not the applications & their data

About Flashing Custom ROM (RR/PA) on LG G3 D855

Greetings everyone. I wish to know more about flashing Resurrection Remix...
I watched the brief instruction on official XDA thread but I wish to know more detail...
- Current Phone Status -
My G3 D855, 32 GB memory, is running stock Android 4.4.2, ROM version “V10n-HKG-XX”, stock recovery, rooted with PurpleDrake (script by xda developer”. Kernel version 3.4.0. All things are stock except I have rooted, with SuperSU.
- Reason of wanting to flash Remix ROM -
I wish to change resolution to 1080x1920, even 720x1280. So I did this using build.prop editing and “wm size 1080x1920”，“wm density 480”. However in stock rom, build in LG apps like Phone, Messaging, Calender will crash. I fix this by installing Xposed & app settings with DPI 530. But I don’t quite want this to be the solution...
Plus I noticed there really are battery difference between 1440x2560 and lower resolution. So I started to think about custom Rom. I found that Resurrection Remix and Paranoid Android are quite slim, good looking, most importantly very customizable.
And Stock ROM has many software that I don’t need, so I wish to give it a try.
- My question -
I haven’t flash any custom rom before (I have flashed on my previous phone but messed up quite a bit).
- So I wished to know what is the prerequisite, anything that need to pay good attention into? I want to avoid bootloop or hard brick...
- Should I install official TWRP recovery on my current status and make a full system backup image? (is that called nandroid backup?)
- If any error occured, can I use TWRP recovery to restore everything in my current status (everything in stock but have root access)?
- Are the custom roms contain build-in Root access? Because I want the phone to be rooted.
- I use LG Flash tool 2014 to flash stock firmware kdz files), with CRC method to completely wipe the phone and back to stock. Is this method still applicable if I want to back to stock after flashing RR rom? Because I want everything to be clean each time I flash a new system...
- I watched YouTube video that changing AOSP rom resolution won’t mess up icons or apps. So I can still receive SMS, dial, calender sync to Google etc. Correct?
--------------------
Finally, I wish to flash the latest STABLE version of the Remix ROM / Paranoid Android ROM. Would be good to hear some recommendations. I wish things to be more customizable and slim. Thanks for reading this long article in advance!

1- you're good to go now, you don't need any prerequisite, you should pay attention to the steps you make to flash TWRP and rom not to do it wrong.
2-yes you should install latest official TWRP for your phone and backup these partitions (system, data, boot, efs -if available-), and that is nandroid backup, and you will use TWRP to flash RR or PA.
3-yes you can restore from nandroid backup.
4-yes both roms has built-in root access that can be activated from developer options, and you can simply flash SuperSU.zip in recovery after the rom and gapps to use SuperSU app to manage root access if you don't like the built-in root.
5-yes this method is still applicable, because all you need to get back to your stock or flash another rom is wipe (system, data, cache, dalvik cache) and flash the rom, so as long as the tool does that, then you're good.
Also if you're not sure you can do the wiping in TWRP first, then boot into download mode and then flash with the tool.
6-changing dpi in custom roms may cause some apps to crash, however i don't recommend lowering the dpi value too much or you will get some issues like that.

Mr. Migo, thank you for replying. But I have more to ask/... Sorry for being annoying, because I am a beginner and I wish to make things clear, to minimize the chance of accident...
1. you said i'm good to go now, but shall i need to .kdz flash the stock v21a-HKG-xx which is Android 5.0 first? because i remeber RR rom's post in xda said i should upgrade to 5.0 first... i'm not quite sure...
https://forum.xda-developers.com/lg-g3/development/rom-t3507493
above is the link of the rom, I wish to know is my phone appropriate for doing this before everything... Hope Mr. migo you can have a look for me when you have time...
2. regarding twrp recovery, i read this: https://forum.xda-developers.com/lg-g3/development/recovery-twrp-3-0-0-0-t3309475?nocache=1 however in the official download link it said twrp for d855 europe... I'm D855 but not europe... If I want to flash official latest twrp recovery, shall i use 'twrp manager' from google play?
plus, it said i should backup the original stock recovery, how do i do that?
3. Doing a full nandroid backup which can be used to completely restore current status, only including 'system, data, boot, efs', the 4 partition, correct? because i didn't use any custom recovery before, so i wish to know more... any other things need to pay attention before doing a full nandroid backup?
4. I wonder which version of Gapps I should flash / appropriate for the RR remix... the post said Download Gapps (ARM 7.1 Pico/Nano/Other), but which I should use? 'cuz it is essential I think...
5. Hope you can check my understanding below: if i want to flash RR rom now, should:
--- flash official latest twrp recovery
--- go to recovery mode (twrp) & backup 'system, data, boot, efs', the 4 partition in ext.sd card
--- still in twrp recovery, do 4 wipes 'system, data, cache, dalvik cache' (I want a very clean installation, not 1 byte of previous rom data will be left, so how can i wipe it to very clean status?)
--- after 4 or 5 wipes, do i need to press 'factory reset', 'wipe cache partition' these 2 options?
--- alright after all the cleaning, still in recovery while the device is like a shell (nothing, no OS inside), browse to ext.sd card which I will be putting the .zip ROM file, and flash it.
--- after completing flashing, do i need to press 'factory reset', 'wipe cache partition' these 2 options?
--- then I shall flash gapps?
--- then, reboot device, and I am done?
6. I want to know is this ROM really appropriate for my phone... because all those screenshots are in foreign language, not even English, I live in Hong Kong and I bought this phone in Hong Kong... So will the RR remix rom not compatible with certain regions...
7. Again this link: https://forum.xda-developers.com/lg-g3/development/rom-t3507493 below 'Download on AndroidFileHost (AFH)', there are several version built in diff. dates. It seems that the latest build is Nougat android 7.0...? Willing to try that, but is it better for me to go to Resurection remix official site and search for d855, then download the latest, stable (not Nightly) builds?
8. This is how i change DPI. I calculate using dpi calculator, 1440x2560, 5.5inch device should have 534.06... dpi, then i use nomone resolutrion changer to view the default settings (1440x2560, 5.5inch = 640 dpi), then 640 / 534.06 = 1.19836...
then, dpi calculator agaim -> 720x1280, 5.5inch device should have 267.6532... dpi, then 267.6532 times 1.19836 = 320, I will do this in terminal with command 'wm size 720x1280', then 'wm density 320'. and go to build.prop, find "ro.lcd.sf.density' change value to 320, then reboot.
Is my method correct? I think it is not too low... Approproate value for 720x1280 res. monitor.
----------
That's all for now, sorry for so many questions... really... I just wish to minimize and get everything clear before proceeding, since this can be dangerous... thanks a ton Mr. Migo.

That's all for now, sorry for so many questions... really... I just wish to minimize and get everything clear before proceeding, since this can be dangerous... thanks a ton Mr. Migo.

1-sorry i didn't know that you have a lollipop update, yes you must upgrade to lollipop first to have the latest bootloader.
2-about TWRP, if the model number is d855, so it's for you, the country won't matter, like for me if i have i9100g so i can't flash TWRP for the i9100, so if you are sure about the model number then it's ok.
You can flash it with adb or by using flashify app from phone, you don't have to use the TWRP app.
As your phone is already rooted, you can backup stock kernel and stock recovery using Flashify app, just download it from playstore and open it, grant root access and choose the tile "backup/restore" and you will see the options to backup stock kernel and recovery.
4- gapps are not complicated, "ARM" is your processor architecture, "7.1" is the android version you choose based on the rom you are flashing, "Pico, Nano.." these are the gapps types, pico has the least requirements to run the play store, Nano has extra functionality that isn't available in play store, and micro has more apps..and so on, However, if you want to understand more about it, you can read the wiki of each package from here.
5- flash the TWRP, in recovery backup is based on the phone partitions, every phone has those 3 partitions (system, data, boot) some phones have efs and some not, so when you are in recovery you will see what part are available to backup, now for wiping, you only need to wipe once not 3 or 4 times!, navigate to wipe and choose advanced wipe and mark (system, data, cache, dalvik cache) and swipe to wipe, you won't need to use "factory reset/wipe cache partition" option at all, now flash the Rom and then Flash Gapps directly, no wipe between, now reboot and wait, that's it!!
6- as i told you in (2), your model number is d855 and the rom is for d855 then it's compatible with your phone, people use their own language in their phones so don't let that bother you.
7- RR remix doesn't have nightlies and never called stable it's only official, if you go to the download page of RR of your phone in sourcefrog you will see only "official" and the "nightly" folder will be empty, however, latest build for you is in 12/2 but i don't know what CK is in the file name, i suggest you ask in the rom thread what CK mean because i don't know.
8- in nogut you don't have to do any calculations, in display settings of the rom, there is an option called "screen size" where you can adjust it to (small, smaller, smallest, normal), anyway you method can do the job if you didn't like this new feature in nogut.
OMG, i never wrote that much..?

Sir you helped me alot, no problem I pressed the thanks button! But can I continue asking? Won't be too much I guess, hope I didn't bother your time...
1. That means I have to use LG Flash tool to flash stock 5.0 firmware (.kdz)? Which is 'V21a-HKG-XX'. But stock firmware 6.0 (V30c-HKG-XX) had released too. What exactly should I do beforehand...? Because before you said I am good to go but there seems to be something missing...... I am not challenging you sir, I just want to be sure and not missing any important steps so that my phone turns dead... (for sure information I wish to flash resurrection remix latest official 7.0 Nougat firmware)
2. So if what said in (1) is true, I need to flash stock 5.0 or 6.0 kdz first to turn the phone into clean stock 5.0/6.0, root it , then use Flashify to backup stock kernel/recovery (these are 2 things? I thought that was the same thing...), correct?
3. I found twrp recovery here: https://twrp.me/devices/lgg3europe.html by typing 'device' on the upper right, then type D855, all it appeared is only "TWRP for LG G3 Europe"... Plus, I notice in ROOT G3.com that twrp had different version for Android 5.0 and 6.0... So I am confused again, because if the above link is official website for twrp, it didn;t state that lollipop(5.0) and kitkat(4.4) has different twrp...
4. Derived from (3), as I am not sure which twrp .zip file should I download, I saw on official twrp web that it recommends "official twrp app" to install the recovery, I think it can detect my device and find the only appropriate one for me? I saw quite some people flash it using Flashify app, but I just want to know more and make it clear...
5. https://forum.xda-developers.com/lg-g3/development/rom-t3543815 <- In this page, I found
"ROM OS Version: 7.x Nougat
ROM Kernel: Linux 3.4.x
ROM Firmware Required: 4.4.2/6.0 + TWRP
Based On: LineageOS"
On below. Is that mean 4.4.2 or 6.0 as the current system android version is also okay for flashing it?
6. In this page, which is another RR rom "stating" it is official: https://forum.xda-developers.com/lg-g3/development/rom-t3507493, said that:
GApps - opengapps.org (ARM-7.1-PICO)
On below. Firstly, can I download Gapps on here: http://opengapps.org/?
If possible, than shall I choose like what it said, ARM, then 7.1, then PICO ( yes I think I only need minimum package)? Because I am not sure I should use 7.0 or 7.1, and ARM or ARM64...
7. Seems there are quite many version of RR, I googled "resurrection remix' go to their offical page, redirected me to sourceforge, https://sourceforge.net/projects/resurrectionremix/files/d855/Official/ I think I will download the latest date "20170110" version. If I am not wrong this should be the official not nightlies build (you will notice there are nightlies).
Refer back to (6), which type of Gapps should I use... AMR64, ARM, 7.0? 7.1?
8. So wiping 'system, data, cache, dalvik cache' these 4 things will really erase all things and get clean enough?
Also, https://forum.xda-developers.com/lg-g3/development/rom-t3543815 here, below:
-INSTALLATION INSTRUCTIONS-
- Download the latest build
- Download Gapps (ARM 7.1 Pico/Nano/Other)
- Take a nandroid backup
- Recommended - Full wipe and factory reset
- Flash ROM using latest TWRP 3.x Recovery
- Flash Gapps
- Reboot.
- Enjoy!
They recommend press factory reset... Should I do the same? Is it better to press because if the 4 wipe 'system, data, cache, dalvik cache' is clean enough then reset is not needed...
--------------------------------
Opps....... Really sorry sir... When reading your reply one by one that much question appeared again... Really sorry, hope you don't find me annoying... SInce you are the only one reponded and you are experienced, so I wish to grap the chance to learn about it... Thanks a ton. You can have as many thanks button pressed if you want, I have no problem!

1- ok, when they said rom firmware required:4.4.2/6.0
I believe that it's ok to root and backup the recovery, and directly start the process of flashing, because you already have 4.4.2 installed which is kitkat and it's compatible with latest TWRP, you can make sure by re-asking in the rom thread if you can directly install the rom right now or upgrade the firmware to 6.0 first.
2-(2) is connected to (1)
3- just use the latest TWRP you find for your phone in the official TWRP page, you don't have to use TWRP app, you can flash it with flashify, but it's OK if you want to use TWRP app, in fact, it's more safe to use it, and it has nothing to do with your android version because you will format the phone after all.
4-(4) is connected to (3)
5-(5) is connected to (1) and (2)
6-you choose ARM then 7.1 then pico or nano
and again, you must know that android version must be known in order to choose right, so if it's 7.0 then choose 7.0 gapps, and if it 7.1 or 7.1.1 the choose 7.1 gapps.
7- (7) is connected to (6)
8-yea. Wiping those 4 is completely enough, and don't worry about (factory reset) because it's a part of the full wipe, (factory reset) means wiping data, cache, and dalvik cache, which is already a part of the wiping process.
No problem, it's ok to ask, we all want things to go well

Okay. Some offtopic question if you don`t mind.
- Did you use any app to manage app start on boot? I mean when you boot the phone which app will auto start. I knew that AutoStart and ROM Tool box pro contains that option but I dont know how the process works.
- Which app you use to kill tasks? I use Greenify to hibernate apps when locked screen，plus recent task built-in to do the job. Any good suggestion?
- Do you use Titanium Backup to uninstall system app? I will but sometimes I am not sure what the app does but still think its useless to me and delete it. Such as WAP service. I mean in stock firmware，which still dont know although Googled. Do you know how can i know what the app does?
- What is the custom rom you recommend the most and what is the good point of it?
- I have installed Xposed framework in my current status, I mean stock rom, although I am goong to wipe anything but will it affect the process? Shall I clean uninstall it first?
I think thats it. Almost finish my questions. Thanks again.

1- ES Task Manager, i used it to manage start up apps.
2- i also use greenify along with an app called "Advanced Task Killer Free", they make a good team for me ?
3- i don't use Titanium backup, uninstalling system app is an easy process and can be done using many apps, for me, i use Lucky Patcher to uninstall system apps, works good for me.
4-custom roms differ from phone to another, for my s2 i use AICP, i always liked it in marshmallow and in nogut, i also used RR but it has a huge battery drain, also many users like XOSP, it's a wonderful project, and it's very common, so overall i use AOSP roms, but when it comes to battery life, i use Neat Rom, it's stock based with many customizations and great kernel too.
5-no xposed won't affect the process, because you will wipe everything eventually.

I will try the process later to see of this works... But...
1. customization & battery are the 2 factors I concern, i dont know how to see if the rom has good custmization and battery tweaks in their threads... https://forum.xda-developers.com/lg-g3/development Any tip or suggestion?
2. titanium backup has the option of "wipe data" of app when uninstall, which I think is cleaner for uninstalling, I mean no leftover of apps including system app. or you have better ideas about doing this?
3. Internal Storage is part of the full wipe, is it? I mean "system"/"data"/"cache"/"dalvik cache", because it contains many current status' files, I should wipe it. Correct?
4. Can I wipe external SD card in TWRP after installing the rom? Because I saw Android/Data or Android/obb files there, so I think some data files are in ext. SD card. For clean installation, I should wipe them too right?
Thanks.

Well, the as a 8 don't have lg g3 then, it's a something i can't advice you about, but AICP is a great project that can balance between both; battery life and customizations and it has a good performance also.
Uninstalling apps isn't that big deal, when an app is removed all its data is removed except media files and some low size or even empty folders, so it's a something i don't usually think off neither should you, it's nothing.
Internal storage isn't a part of "full wipe", but wiping it is up to you, it's your choice.
You do too much thinking, you don't need to wipe neither internal nor external sdcard, i have a 16GB phone and i don't think that much about this

[i9300] CM13 stuck on "Preparing apps" after update

Hello everyone,
A friend of mine has a Galaxy S3 i9300 which I installed years ago CM13. I don't what update he installed but now the phone starts with the screen "Preparing X of Y apps" => when we think it's over (because the phone restarts at the end), well it does another "Preparing X of Y apps", and so on
I don't know what I should do : repair it by flashing the old zip (cm13-2016...-.zip) but maybe I have to "wipe cache" and "wipe dalvik" before?
Or maybe I have to wipe everything (wipe cache, wipe dalvik...) in order to flash LineageOS ? I'd like to follow this path anyway but how can I save the data of my friend such as SMS, Contacts.. ?
It has TWRP and I can mount the partitions and access them via PC
Thank you for your help

Go back to the older gapps.

That's what could cause the problem ? Do you have a link about which version of Gapps should I install ? I'm gonna try that by flashing them via TWRP
Should I do a wipe or anything else ?

The only thing you could wipe is cache without having to start over. I doubt that'll fix anything. You can try sourcing another copy of that version to see if the one you have is corrupt.. Otherwise it's probably going to be that it simply doesn't support your os.

What apps did he install?
Some apps make the system crash. It's a bug that only happens in cm12/13 based roms. Try upgrading his phone to lineageos or install android 4.4

If it's me I'd upgrade to LineageOS 14.1 directly But I was thinking about its data such as SMS, MMS...
I just did a Nandroid Backup using TWRP => is it possible after installing LineageOS 14.1 using clean method (after wiping data, cache and system I think ?) that I can retrieve the data by restoring TWRP backup ? (without the cm13 of course)

I am not sure, try restoring only the data partition over a clean lineage install. I don't like dirty flashing, but you have no solution other than try this. If it doesn't work it's time to start from zero.
I was almost forgetting, try flash cm13 zip, then restore data partition from twrp and if you can boot, do a Titanium backup of the data you want. Then do a clean install of lineage and try to restore the titanium backup

I tried to flash old cm13 zip that I have (without gapps) => it boots
Then I tried via TWRP to restore only data partition => Stuck again with "Preparing apps" xP
What If I flash LineageOS 14.1 from scratch but use Titanium Backup to extract data from Nandroid backup ?

I think you need the Pro version of Titanium to do that. I don't know any alternative

After many attempts, I finally managed to make it work again
Here's what I do (maybe it could help other people)
Step 1: I restored the Nandroid backup I made via TWRP
=> At this point Cyanogenmod13 is back
Step 2: I found a Cyanogenmod14.1 zip file somewhere on internet (cm-14.1-20161225-NIGHTLY-i9300.zip)
=> I flashed it before/after wipe cache/dalvik
Step 3: I flashed Gapps for this version of Android thanks to open-gapps website
=> Last wipe cache/dalvik before Reboot
Step 4: Enjoy
