Thats because people dont post nandroid backups as they contain personal information. Your best bet would be to look for a stock RUU for your device.

There should be one on the HTC site. They normally keep a RUU for each model.
A nandroid from someone elses device will cause you more issues then anything as it contains Device files that are unique to each device like IMEI and others.

Not exactly true. It's perfectly safe and acceptable to share a nandroid of /system and /boot partitions, they don't contain any user specific data and can be useful for restoring the system in the absence of an RUU.

Not sure how safe that would be when the system partition contains the Efs folder which controls the IMEI.
I have not used nandroid in a long time so I might have to look into how the recoveries handle these.

HTC One doesn't have an /efs partition, but do recall that on Samsung devices.
Even so, it's a mount point to a separate partition so it's not backed up with the /system partition. Check cat /proc/mounts to be certain.

You won't get your IMEI back by flashing a 3-part-Rom.
What problem with your IMEI do you have? Starting with 004999...?

Hallo! I have a problem where mobile connection doesn't work. When I try to connect manually it doesn't work it just gives me an error with no details in it. This happened after attempt on installation of Mackay kernel it worked but I noticed the mobile connection was dead after a while I ran a restore but stil the same problem. The efs folder is empty with a lost+found folder there is also nothing in that folder. When I click manage mobile contract it tells me that I need to put the SIM card in but it is inserted. HELP!!

Is your IMEI still intact or does it begin with something like 0044?
(If you don't know where to find it, go Settings -> About Device -> Status)

Did you ever do nandroid backup before? If yes, it contains also the efs folder.
BTW, if nandroid backup was done with different ROM, kernel or CWM version, don't try to restore it with Mackay kernel!!
You must flash as furst the same ROM and same kernel and use the same CWM recovery version to successfully restore your nandroid backup.
Otherwise, you could flash some stock firmware and imei usually returns then. People report that Gingerbread JVU usually restores the imei number quite regularly. If your current ROM uses different partitions than stock firmware, you may have to flash also the PIT file to make step back to stock with success, PIT file will do proper re-partition.
Otherwise, there are quite many threads about how to restore lost imei on the i9000. Take some time browsing around.

Great!
Now backup your whole efs folder with the terminal emulator or ADB and save it on several places (different folders on internal and external SD as well as on your PC). It is explained how to do it in my thread.
BTW, on this forum it is kind of nice to click on "thanks" button leftmost beyond all helpful posts.

I've already written you: it was described in my newest thread, I've posted it also here:

The same commands like in the terminal emulator can be done by the ADB as well.
You can easily find good threads here on XDA forum how to backup & restore IMEI
But for great tipps you should not forget to "klick" the thanks button ...it doesn`t hurt :fingers-crossed::good::laugh:

I'd say yes, but it's personal preference really. If you'd happen to lose your EFS, then you're screwed because it contains your IMEI, MAC Address, Wifi MAC Address, etc...
If you flash a lot of ROMs I would say yes, but if you flash zero ROMs or very few, then I would say it's not totally necessary. It only takes one bad flash to ruin your EFS.
No one replied so I figured, why not?

Just do a regular Nandroid backup in recovery via TWRP and there is a check box for the EFS partition. Check it along with anything else you might want to back up at the time. Make sure you are on the latest TWRP version, otherwise you may not have this option.

I wasn't the one who originally asked the question I just saw something about needing to backup something. I'm kinda paranoid about backing things up. Few more things to ask. Do you back EFS up with every nandroid and just restore it with everything else, or do you keep a copy of just the EFS itself and restore it separately if something messes up?

I do a one time back of of just the EFS for each major android update, then erase the older version.
Like right now I have the efs backup for 5.0.2. When 5.1 comes to play I will back that up and then delete the 5.0.2. Just my preference

One more question. Can you make a backup of just the EFS partition and restore just that partition or do you have to restore a complete nandroid of the whole system? Thanks I'm sure this is all basic stuff to you but I seem to learn something new every day.

I'm having some problems with wifi/bluetooth mac address and want to try to format efs partition and then restore it
already have an efs backup made with TWRP but couldn't find the option to format that partition in order to fix any possible FS error.
Did you know how?
Just got a new unit and would like to make a full backup of the factory ROM before proceeding to try out different ROMs. I did find an old thread from 2011 [HOW-TO]Create Custom ODIN Images for Backup/Restore but I'm not entirely sure if this is still accurate advice.
Also, it says that the device needs to be rooted in order to make the backups. My understanding is that if I root the system it will be detected by the system and OTA updating will then be disabled, which is not what I want. So my second question is: Is it really necessary to root and if so what is the best temporary method?

Small piece of advice my friend, be sure to include EFS in the backup to be on the safe side, also I suggest making a copy on a external SD or transferring to a PC
Why efs?

According to TWRP they say:
Some devices have “special partitions” like WiMAX, pds, efs, etc. These partitions almost never need to be included in a normal backup.

I already did one restore from my backup which had not included efs and it worked ok. What exactly is efs and why would we need it?

The EFS folder contains important information from the phone, like the IMEI for example, and if it gets erased by error it may affect your ability to successfully connect to a provider. Backups in TWRP will give you the option to backup important partitions one of those is the EFS folder, alternatively you may also use an application to make a backup (requires root) like EFS Manager(IMEI)-Note4 on the play store.
It's my understanding that the Persist partition/folder contains some data unique to the device, such as IMEI and MAC addresses.
If I lost my Persist partition, would it be possible to restore it without having a backup?
See https://forum.xda-developers.com/mi-a2/how-to/how-to-fix-sensors-camera-stock-pie-10-t3914885
BTW, "Search" woks in these forums.
Sorry, I've seen that thread, but I'm more interested in the theoretical aspect. Shouldn't flashing a Persist partition that doesn't come from a backup override some device-specific data? Or it is completely safe and it will just revert to the original state?
