I have a few questions - Huawei P10 Plus Questions & Answers

I am newbie to Android/Rooting and I would like to root my P10 Plus, but I am having a few questions because I have rooted my P10 Plus before and the entire OS got wiped somehow, and I had to pay about 100 USD to get my phone replaced, so my questions are:
1. TWRP doesn't work for backing up DATA, so what is exactly stored in DATA?
2. Can I restore from a backup if I got my entire system wiped somehow?
3. What apps can harm my device because of the DATA encryption issue?
4. Can I use KangVIP ROM if I had my entire system wiped?
5. Is it safe to use KangVIP ROM?
6. Can I lock my bootloader after rooting?
7. Can I hide the "open bootloader" message, to keep my warranty?

[Q] Access to /data folder without losing data

Hi
I recently got a Nexus 4 after always having had iPhone, so I am quite new to this. =)
Is it possible to root a Nexus 4 without losing the data folder? Either by simply never deleting it or is there any way to get a backup of everything in the data folder(including hidden files and everything in /data/app, etc.) to my computer(windows or mac), when it isin't rooted?
All the rooting guides I have looked at until now says that they will wipe the phone, but I also read a discussion that said it were possible to gain complete access to the data folder by either manually rooting the phone or by not unlocking the bootloader? I posted somewhere else and someone there said that what I want is SU in the OS, but I am not sure about that, since I haven't heard more.
Thank you =)
You can root without wiping data. The trick is to not boot into Android after unlocking bootloader. You do things like this:
1. Setup your pc ( drivers, fastboot )
2. Unlock your bootloader
From now on, you must not boot normally, or else your phone will be wiped.
3. Flash a custom recovery.
4. Enter recovery
5. Wipe cache
6. Flash the SuperSu zip to root.
7. Reboot.
Now you should be rooted, and your data should not be wiped. But I'd make a backup is I were you.

Backup existing Data after fresh install of TWRP before ROOT

Hello,
I have an S7Edge and looking to flash it. I am currently in Nougat 7.0 and would like to backup my data before proceeding with the root.
I have flashed the phone with TWRP but when following this tutorial: https://forum.xda-developers.com/s7...overy-official-twrp-hero2lte-3-0-0-0-t3334084
People say that you have to format the Data Partition in order to proceed with the installation of SuperSu and NO Dm verity.
Is there a way to backup my phone data [w or w/o TWRP] before ROOTING my phone with TWRP (format data partition to decrypt, install no dm verity and install super su)? This is so after my phone is rooted, I can restore all the apps, pictures, etc.
Thank you for the help! :fingers-crossed:

Hi,
Thank your forwarding me to your thread. I think I figured out a way to fully back it up with the following steps:
1) If you are in Nougat, downgrade to 6.0.1
2) Root your phone by flashing CF-Auto-Root in Odin (it should not wipe any data)
3) Once phone is rooted, you can backup your phone with TitaniumBackup or Flashfire
4) Save the backup in your sd or other external
5) Update phone with official or custom Nougat FW
6) Root phone via custom recovery (TWRP), will have to format all your data
7) One phone fully booted up and rooted, restore from backup with TitaniumBackup or Flashfire
Let me know how it goes

2nd time flashing what do I need to know before do a mess?

Hi XDA!
I am using FreedomOS 1.9 so I'd like to change it to Resurrection Remix-OS.
Before do it, I have the next questions:
I already Have the .img from Codework's TWRP, can I dirty flash it through my current TWRP to "upgrade" it or should I just use cmd via Windows with fastboot mode?
I want to wipe all my actual data (apps, media, etc) to let the OP5 empty and begin form 0? Can I wipe data now that I am in FreedomOS and it will start the rom like the 1st time? Will may be some problems if I do it?
I have my OP encrypted, is this a problem? If I must unencrypt it, how can I do it?
I hope you can help me, I do not want to become my OP5 in a paperweight.
Thank you for the help! :fingers-crossed:
Make sure the following,
1. TWRP should be latest, atleast 3.2.1 (check RR ROM about which version of TWRP it suggests)
2. Most of the custom ROM suggests clean flash i.e wipe Dalvik, Cache, System and Data in TWRP
3. Take complete backup of your apps via Titanium Backup or any similar app
4. Before you flash, make sure to take a full system backup in TWRP and transfer to your PC just in case
5. Secure all your images, videos, files from your device internal memory to your PC just in case your phone gets formatted
6. If the ROM sugest to do format data in TWRP (TWRP > Wipe > Format data), it will decrypt your phone and consequently you will loose all your information from your internal memory, and this is the reason why you have take full copy of your info as explained in step 5 above
As long as you make sure the steps mentioned above are taken care, you are good to go..

How to backup apps before unlocking bootloader and restore apps

I have an EU H870 with V20g-EUR-xx version 8.0.0 (from Settings-->About Phone-->Software Info)
I have many apps already installed with data
I want to unlock the bootloader, install TWRP, install custom ROM, install Magisk (for root), restore my user apps+data
I realise that unlocking the bootloader will wipe out my user data (factory reset) so how do I backup all the apps+data beforehand and then restore them at the end? I had an LG G4 before and unlocked the bootloader when I first got it (second-hand already out of warranty) but this G6 was quite new so didn't want to unlock straightaway. I have used Titanium Backup on G4 but it won't work on G6 as I don't have root yet so I seem to be in a loop here (need backup before root, need root to backup).
I have also heard of issues with TWRP and re-encryption issues preventing TWRP restoring TWRP backups.
Can someone help with a definitive list of instructions, listing other G6 guides is OK. I have searched the G6 Guides section and G6 Q&A section but couldn't find the full story.
I am just so lost at the moment and don't want to lose my data. I know my pictures/music are OK as I can copy them from the internal storage to an SD card and copy them back.
Thanks
Darren

First time ever installing a custom ROM. I have some questions. Moto G5 Plus stock.

I have a completely stock Moto G5 Plus (XT1683 - 2GB of RAM) on stock Oreo 8.1 and I want to use the Pixel Experience 10. I've watched some tutorials online but I still have some questions:
1. I've seen many people complaining that they lost their IMEI and 4G, but I still couldn't figure out if that only happened with people that downgraded from a custom Oreo rom to a stock Nougat or if there's a chance of that happening by installing any custom ROM. My phone has the latest official Oreo version and I've never messed with the system before. Is my phone still at risk of losing its IMEI if I install Pixel Experience 10? What did those people do wrong?
2. Now let's talk about the procedures I have to take. After unlocking the bootloader it will wipe my system, right? If that's so, should I let it boot again into Android and turn off or should I immediately get into fastboot and flash TWRP? Will it make a difference? Will the persist and efs partitions be there on TWRP to be backed up or do I need to let Android boot so it can make them first?
3. After everything, if I get into TWRP and it asks for a password, should I just cancel and wipe the partitions to remove the encryption (can I keep the internal storage?) or do I need to install that dm-verity file instead? As I understand the dm-verity if only for when rooting the phone while keeping the stock system, right? (I don't plan to root my phone, only install a custom ROM. It would also be good if I could keep my files, but if I can't, that's fine too.)
My original plan was the following, please take a look to see if i'll do things correctly.
1. Unlock the bootloader
2. Install TWRP immediately, before it even has a chance to restart
3. If TWRP asks for a password, skip and wipe all the partitions, if it doesn't, wipe them anyway to install the new ROM.
4. Backup efs and persist to my SD Card (will they even be there after I wipe the partitions?)
5. Right after that install the custom ROM
6. Reboot, not get into a bootloop and still have my IMEI. Profit.
Is everything right or did I misunderstand something?
Thanks!

Answer for your questions
1) losing of IMEI no is possible on custom ROM too, but taking the backup of EFS and persist will retrieve them, so no problem. And losing of IMEI is random occur when moving from one rom to other.
2) just let the android boot once, so everything get loads up with unlock bootloader (no need to setup).
3)after installing the twrp, it won't ask for password since your device got format when unlocking bootloader, so it won't ask. If you want to remove encryption then format< type yes. It will remove your encryption.
4) for talking backup of EFS and persist use this method.
Code:
Use the following command to create a backup and save it at /sdcard/persist.img:
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
To restore use the following command:
dd if=/sdcard/persist.img of=/dev/block/bootdevice/by-name/persist
If you have saved a backup using different name then use that name instead.
And seeing your plan, everything seem good, you can continue with your plan.
Note:- for some user PE won't work for them with 2gb version, so I suggest you to take a backup of stock ROM or keep an other rom file in case it needed.
