Doubts about IMEI 0 problem - Moto G5S Plus Questions & Answers

Hi everybody,
I have a stock Oreo Moto g5s plus and I want to try a pie custom rom. I know how to do that, but I have some doubts about the IMEI 0 problem. If I make a backup of stock rom, can I flash it in future in case of IMEI 0 and solve the problem?
Anyway, which partitions should I backup (instead of whole rom) to be safe in future? Efs and the persist ones? And can I do it only through recovery or adb is needed? Is there a guide in XDA?
Thanks in advance

I would suggest backing up everything for safety's sake. If needed you can restore only the parts needed such as efs, etc. If you come across a certain problem folks will recommend what to restore to fix it (whole ROM or just modem/efs, etc.). Can't go wrong having a full backup on hand.

NANDroid backup

what is a nandroid? how do you perform a NANDroid backup of your current ROM? im going to cm7 stable from kj1. just wondering cause it says in the steps to install cm7. thanks..sorry for the noob ques..
its making a complete backup of ur current rom settings,apps and all. with i897 gingerbread roms i dont think u can restore a nandroid backup. but u would normally do a backup in recovery with cwm.
yes, nandroid on i897 ginger roms do not work.
but the procedure would be to make a backup. then if you flash a different rom from what the backup was made from you would have to flash the rom back that was backed up THEN restore the nandroid and it will be like you never flashed away from that rom.
DO NOT EVER restore a nandroid to a set up it was not backed up on, it will bootloop.

can you expound on that please...hahaha..sorry im reading it over and over..just need to clarify..what you mean? thanks btw guys for the reply..so basically nandroid backs up your rom..cause just the name sounded confusing..i mean why name it nandroid when they can just say in the intructions before flashing a rom to just "back up" your rom..haha..i thought nandroid was something else..cause i heard other people saying something about efs or whatever and backing it up but i dont even know what that is especially..thanks though for replies..got it..
Say you back up your current ROM, then flash another. You can't just restore ROM A onto ROM b. You have to flash back to ROM A and THEN restore the nandroid and it will be like you never flashed ROM b. All of you settings and everything will be intact.
Efs is totally different, that is a partition that contains your phones individual data, it's imei which you have to manually backup it's not included in a nandroid.
Components backed up by NANDroid
Which of these components does NANDROID back up?
- bootloaders?
- kernel?
- system apps and other apps?
- modems?
- other parts of the OS?
Thanks for sharing the knowledge.
The firmware and system settings.
No kernel
No bootloader
No modem

Kindly clarify this please, i want to backup my stock rom before going custom.
So inorder to do a complete backup, we need to do a nandroid backup and also backup imei separately?? and then restore both of them when i flash back to stock??

They are two separate issues, really, but you are correct that you should back up both.
Nandroid lets you go back to a previous state, as long as you flash back to the correct ROM before you restore it. It will not let you restore data to your new installation, though. If you want to restore your applications in your new ROM, you can download Titanium Backup from the market which will let you batch save your applications now and restore them on your new ROM (It can also save and restore system data, but don't restore system data between ROMs, it causes all sorts of weird issues).
Backing up your EFS folder is something you should do, but hopefully will never have to restore. Your EFS folder contains information about your phone and should never actually get touched in any way when flashing ROMs. However, things go wrong and sometimes this folder ends up getting corrupted for whatever reason, which can lead to a corrupt IMEI code and no service. If this were to happen, you would restore you EFS from backup. I think it's safe to say most of us have never had to actually do this, but better safe than sorry. You can do a search for backing it up and find several threads about it.
Happy flashing!
lol...I was about to do nandroid backup! These post wre real helpful...thank you!
See this thread in the Development Forum for Corn Kernel... It has a working nandroid. BTW, that kernel is for i897 Gingerbread Roms.

When I run a nandroid backup I see it processing these:
- boot image
- recovery image
- system
- data
- datadata
- .android_secure
- cache
- sd-ext
Can anyone explain some of these terms to me? I am pretty new to all this.
This thread has all the goodies defined pretty well http://forum.xda-developers.com/showthread.php?t=1093062

You will need to first get it on the same modded ROM and then flash the backup. They will then be identicle
Hello,
This is the thread I was looking for. It just tackles top backup/restore issues I want to be positive of before tinkering around.
Now, what app is capable of doing a nandroid backup, if any? RomManager?
If a nandroid backup consists of the firmware and system settings but no kernel, bootloader or modem, how are these three backed up then?
My goal is making a stock unrooted (if possible) backup.
A concerning restoring, from this thread I understand that the restore process is composed of:
1st restore ROM A (which?)
2nd restore nandroid (which?)
3rd restore data/apps (Titanium is able to)
4th restore EFS folder (how?)
Please, correct/suggest. I appreciate.
Greetings,

First of all, you have revived an old thread with now false information. A nandroid does include modem and kernel. Bootloaders can't be backed up, and there really wouldn't be a point in that. No app can do a backup, and please don't use ROM manager; it's obsolete. As for your steps: You probably only need to flash a ROM first if the partition table is being changed. Meaning you can't restore a Samsung ROM over an AOSP ROM. You won't need to use titanium backup because you will have restored the phone to the exact state it was when you took the backup. Meaning there won't be anything to restore. Efs? Don't touch it, we never will be deleting it.

Modems and kernels ARE NOT backed up in a Nandroid...
Hello,
@korockinout13: I don't think I'm providing false info. Actually, i've been gathering from the thread. I think there's some disagreement on what a nandroid backup really backs up from the views expressed in the thread. Plus, it's pure netiquette not opening new threads for a topic already started somewhere else in a forum. It's power ecology. No hard feelings, though.
Thank you and b-eock for your replies. I think I'd rather use cwm instead.
My goal is still the same: making a stock unrooted (if possible) backup as there are no roms available for my brand new Mini:
pda S5570XWKQG
phone S5570XWKQ5
csc S5570YOGKQ3
android version 2.3.4
Kernel 2.6.35
Thank you both!

Someone told me about the modem part, so I'm not really sure about that. But if it doesn't backup the kernel, why does restoring a nandroid put you back on the kernel you had previously (i.e. Glitch)?

[Q] Backup stock ROM before installing CM7.x

Hi all. Due apologies in advance if I sound like a total newbie.
I'm looking to install CM 7.x on my O2X. Before that, I want to backup my stock LG ROM so that I can restore it in the event I need to send the device back to the service centre for any reason. Would appreciate any help or pointers for backing up and restoring the stock ROM on my handset.

To have a perfect restore you'll have to get rid of CWM either, that means restoring original recovery partition. The only way to do this is to flash an original complete ROM with nvflash.
There is a thread about this with all original Froyo roms, should be easy to find in dev section.
After backup LG update tool will get you to the latest version and it will be ok to go back for repair...

i think you don't need to backup stock rom, you only backup your data and system data with titanium backup. because there is tool like nvflash that's already mention or smartflash tool to flash your phone to the original stock rom

Yes I supposed he knows that I assumed he wanted to know how to restore a complete stock ROM including the stock recovery to preserve warranty if he needs to get the phone back for repair.

[T-Mobile 626s]: Is there any way to perform a nandroid backup without CWM or TWRP?

Hey folks,
So I want to install xposed framework, but I'm nervous about bricking my phone. The first step in the process is to backup the current rom. Unfortunately for T-Mobile users, there is no custom recovery image that will work with this phone besides CM. CM does not have a backup or restore feature. Does this mean that there is no way to backup or restore the current rom?
I just got this phone because my LG G Stylo got permanently bricked and I have no intention of allowing that to happen again. Is there some other way of performing a backup? Without backup/restore features, CM seems to be about as useful as the stock recovery (useless) in the event of bricking.
i was in the same boat, but Captain_Throwback posted a TWRP recovery that's working on my 626s t-mobile US

Dump original rom, backup before doing changes

Hi all,
I'm just a few days of receiving um Mi5 64 GB and i'm been Reading some stuff on how to change from default rom and even to custom rom.
So my question is before do anything i'd like to be informed on how to do a cpmplete dump or backup of my Mi 5 or if i wanna go back to stock wow to do that that.
Best regards to all.
basically :
unlock the bootloader
install TWRP
run a full nandroid backup using TWRP.
then you've got a stock backup.

Begin to customize phone OS...

Greet, guys!
I do this topic to solve some doubts and help new costumers with flashing OSs... If somebody can help thank you very much in advance.
I have losted and IMEI brick an old celphone making flashs so here are the questions.
- flashing with ADB can lost the IMEI ?
- flashing install TWRP can lost the IMEI?
- If I just do the TWRP install and flash some OSs can I lost IMEIs or brick my celphone?
Just simple question, in my opinion, but lose IMEI is not a thing that I want in the moment.
That's all, guys!
Best regards.
as long as you follow directions and don't do anything crazy, you probably won't brick the phone. i've rooted and installed custom roms on every phone i've had since ics and never permabricked anything. if you lose imei the fix is simple and can be found here:
https://forum.xda-developers.com/moto-g5s-plus/how-to/psa-flash-devices-persist-imei-loss-t3828575
i recommend making sure the data is working before you unlock the bootloader, and checking every box in twrp backup except maybe system image before you flash anything.
Thanks for answer, xtasquee...
I pretend do all TWRP backups before installing. I just have to know If I flash with ADB I'll add data only or erase some data?
When I lost my IMEI in other phone model I cannot restore anyway, that's why I'm carefully.
Tks for link too.
