[Q] Recover rom from non-root Desire

Title says it all.
I am new to the android world and the information you get from a google search is convoluted at best.
I have a desire that I rooted using UnRevoked3. I was however misled by all the research I did that I could make a backup of my system and data before the generic rom was flashed. I now have a rooted phone without any backup to revert back to.
My phone is Ntelos CDMA HTC Desire android 2.1
I do however have access to a non-rooted (same phone and network) phone if it is at all possible to recover the recovery and system partitions without rooting the phone my cousin will let me do so.
Can this be done? if so a detailed explanation of how to do it would be helpful.

If I understand correctly you want to "unroot" you phone. This is done by installing htc Sync and running the appropriate RUU from this thread: http://forum.xda-developers.com/showthread.php?t=695667.
Thre is no reason, besides the fact that you want to return your phone for warranty purposes and/or that you want to have stock system, for you to revert to stock.
Copying and pasting backups seems like a very bad idea since there might be subtle differences between phones which thus might generate more problems than it solves.
I'm not saying that it's not possible, it's not recommended. There are a bunch of other safer alternatives.

Yes I want to revert to stock rom which I no longer have. I just wanted to experiment a little. I never would have done in the first place had I known there would be no going back.
There are no stock roms availibe for my phone. I need a RUU from Ntelos not verison or USCC.

No need to, you can't backup a unrooted rom. Since you are already rooted just make a nandroid of that rom to revert to. Only when things go really wrong you need to use the ruu.

No its just that nobody has sorted out how. I ran the US Cellular update on my phone and got a stock USSC non-root phone working on Ntelos network. I then ran root again to get my data back of course.
Their app runs on windows pc and doesn't require special access such as root. All the capability is there I'm sure. just under lock and key.

What do you mean by getting your data back ? All your data is lost (contacts, apps, messages, etc) when you flash a new ROM. The only things that stay intact are those which you have saved on your SD.

There are plenty of ways to backup stuff from unrooted devices. However non of them provide any useful safety backup regarding rooting or flashing.

If there are ways then that is what I am looking for. I have no memory of Unix/Linux command line. I'm sure I have a text laying around somewhere and could refresh my memory. However I elect to ask those in the know to guide me.
I simply want to get a stock system rom from the same make and model phone on the same network without voiding the warranty on that phone. My service provider had very little bloat ware and didn't remove apps that I found missing in the verizon/US Cell stock roms. My phone being root or not is not the question. For that I don't care accept if I ever need warranty work done. And that is just my luck sometimes so.. better safe than sorry.

[Q] What to backup before flashing CM10?

Just got an S3 and I absolutely hate the unpolished and laggy Samsung skinning of Android. I want to flash CM10, but would like to know what I should back up first in case some critical information gets lost. This is a virgin phone, no apps or user data need to be backed so no need to worry about that. However, I would like to know how to back up IMEI, device ID, etc. Is it enough just to back up the /efs partition? If not, what else should I be backing up?
Thanks in advance

Read this and this.
It was pretty overwhelming for me at first, but get through it best you can.
It's easier to do the preventative backup rather than the post repair.

Thank you! I've got experience flashing custom kernels and ROMs, so I should be ok. The only thing is that with every phone model what you need to back up is different, so I wanted to make sure I had the right stuff backed up from my stock S3 before I did anything to it.
So is an IMEI back up via QPST the only thing needed? What about device ID, and other details? Do those need to be backed up and how?

As long as your IMEI is backed up you should be OK. When I first flashed CM10 I made a Nandroid and backed up my IMEI. I have not had any issues with my IMEI or anything but I know people that have.

Just so I'm clear, you:
1) Flashed CWM recovery
2) Did a Nandroid backup of the stock ROM and backed up IMEI
3) Flashed CM10
Right?

Ever since i got my s3 never had to do anything do the IMEI... If you like wasting time i guess you can.. but if your smart with your phone you wont have to consider that extra step.. MAKE SURE U FLASH SGH-I747 roms only!!! and i mean ONLY... (tmo roms work too just make sure you change the apn settings) dont flash any other variants because they have different hardware. you will **** up the bootloader by flashing anyother variant.. Anyway back to the subject. I backup nandroid, then i use ultimate backup (like titanium backup just faster) its by jrummmy and thats it and im good to go to flash custom roms

No Offense Amzi,
but I only flashed STOCK OTA rom upgrades and some mods SPECIFIC to my i747m and I lost my IMEI a few months ago. I have tons of Android Flashing experience, and I did a lot of reading before I did my first S3 flash. My heart sank when it happened. When it happens, you lose your data connection and that's what tipped me off. And from all I have read up till now...no one knows why it RANDOMLY happens. So I would HIGHLY ADVISE to backup those files as per the link(s) I provided.

IMEI and Internal storage problem

I did the stupid mistake of flashing to a custom rom without backing up. Nowhere in custom rom instructions says to backup your /efs folder.
Now in "About device" Baseband version is "Unknown" IMEI is "Unknown". I've searched everywhere for a fix and nothing. I tried the following:
Flash stock rom
Format /data and /cache
On keypad, dial *#7284# ....But i dont get the "Qualcomm USB settings" option so i cant try IMEI repair tools
I tried flashing different kernels and different custom roms
Apart from the IMEI problem, the Device cant access the 16GB internal memory. The stock rom flashes with no error, but when i go to
settings > storage: under "Device memory" its full with only 182MB used by some apps. I thought the memory could be bad, but after flashing
Perseus kernel and swapping external sd card for internal memory I can use the 16GB as external memory. I cant find a fix for that either.
INTERNAL MEMORY UPDATE: it seems that internal memory is mounting read only. Still trying to find a fix
Im currently on "T889UVALK8_T889TMBALK8_TMB" rom with Perseus kernel and using "11extsd2internalsd_gs3_fat32" to swap internal to external memory.
Side note: I bought the phone from a friend 2 days ago. Its the Tmobile version and I used cellunlocker to unlock to use it with AT&T. That worked, until I started messing with ROMS. No warranty available. I am desperately looking on how to fix this since i have no spare phone. Any help is highly appreciated and thank you for your time

Unfortunately sir their just isnt much that can be done for you. If you read about imei loss without a backup its just about incurable. Sorry.
And the remedy for imei restoration without a backup is hit and miss at best as to whether or not it actually will restore your number. Your best bet is to use the search function and try and experiment with different ways of fixing it. Its not like there is much more damage that can be done anyways. You already screwed the pooch and basically have a functional brick.
No one is going to post a step by step guide for you though if thats what youre waiting on. This is a complicated fix and most members wont devote the time to walking you through it
And to the member that said he searched and found no Information. Well thats just not true. Ive read tons of threads and posts about it and know about SEVERAL backup and restore methods.

Thank you for confirming my fear, I was on denial. Im getting a new one on friday. How much do you think I can sell this one for, obviously as a tablet?

Developers need to take more responsibility around here with their threads. A simple "I'm not at fault" is sub par in my opinion. Users popping up with IMEI issues are becoming more a common thing. Didn't somebody make an app to back up your efs partition? Why is there not a link to said app in every ROM and kernel thread? This stuff blows my mind.
As there is a rampant influx of "noobs" watching YouTube videos about rooting their devices (most of which for the first time) with links to ROM threads, their needs to be an influx of responsibility taken by those who cook ROMs and feed them to the general public. The issues with the IMEIs being lost is not a small one. Your device is pretty much done for without a backup. Keep reading, keep trying, but since you had no idea that losing the ability to use your device's radios was even a possibility, not your fault.
Good luck. And sorry. You should have seen a link at the very top of the thread you downloaded your ROM from ... and this whole thing would have been avoided. Here is the link, which is always shared too late and after the fact. App is called andromizer forum.xda-developers.com/showthread.php?t=2080009

Never done it. If you have a new one, just make a backup of the new one and don't mess with it. Now you know to make a backup

Curious
I would like to prevent myself from making this mistake in the future. Are you talking about the same type of back up you would do in TWRP or CWM? Like a nandroid? I've never heard about the backup your talking about, but I have been seeing a lot of people talking about losing their IMEI number and it sounds like really bad news.

Ill give it a try

After what happened to me I haven't messed with other roms. Andromizer can be found here http://forum.xda-developers.com/showthread.php?t=2080009 to make a backup of your /efs. I have also used Nandroid, which you can just download from the "play store". Nandroid apparently does make a backup of everything including /efs and bootloader. As to how to restore from those backups I would like to never find out if it actually works. I have flashed the perseus kernel with clockworkmod recovery and also rooted which allows me to overclock to 1800MHz and im very happy with it. I dont have the urge to flash any roms that "promise" any speed improvements. I have also got rid of the bloatware with titanium backup pro. And of course i made backup with it too just in case i removed something i did not suppose to. All backups are in my external SD card and on dropbox. Call me paranoid but after what ive gone through i call it being safe.

[Q] Anything I should do/know before rooting/clockworkmod/custom ROMs?

So I just got a S4 from T-mobile yesterday, and am planning on putting some roms onto it some time down the road. I'm familiar with the actual installation process, but am just wondering if there's anything I should do before, on the stock rom. I'm aware that (correct me if I'm wrong) you could always return to it later with odin, but I'd like to take care of it first. Things like backing up your efs folder in case your imei changes (happened on my old AT&T captivate), unlocking, etc.
Thanks for your help.

The only way your imei number would change is you get a new phone or a new motherboard. My suggestions is read, read and read before doing anything.
☞Sent from here☜

Root it. Turn off everything you dont use (gestures, etc. ) and use titanium backup to freeze unused apps. Or use google to backup contacts before flashing.

One of the few things that can only be done on the stock ROM is SIM unlock. So, that probably wouldn't be a bad idea to do before you go swapping ROMs whether you'd need it or not. It's definitely not required and I think can be done on the custom TouchWiz ROMs as well; just a thought.

Missing nv_data.bin from stock N7105

Hi All,
Have just ran into something quite strange on my phone and would love to know if there is anyone else who has encountered this.
I have an N7105 running build DMB2 (Android 4.1.2). I rooted my stock ROM some time ago and everything has been travelling along nicely. With KitKat ROMs starting to show up now and my desire to avoid exposing my phone to the new stock 4.3 recovery with KNOX baked into it, I am considering flashing to a custom 4.4 and skipping 4.3 entirely.
This lead me to wanting to make an EFS backup after reading plenty of horror stories on how not doing so can ruin your day. I went and backed up my /efs folder and popped it on my PC. My natural allergy to simplicity then lead me to ask "Is it really that easy?" and found out that the nv_data.bin file stores all the important bits. My /efs folder DOES NOT HAVE an nv_data file of ANY description.
To cover bases: Yes I am rooted, I also tried 2 different file explorers (Solid Explorer and Root Explorer) to make sure it was not a visibility setting in one of them.
I always assumed that the EFS backup "apps" that you can get were just an automated means of copying the folder. Am I wrong in assuming this? Do they pull other data from elsewhere? Why is this supposedly super important file missing from my phone >.>.....
Cheers,
Sheik.

Nobody have any idea what the deal is here?

There is a thread on it somewhere. Because the n7105 has a separate chip for the lte the efs folder can't be backed up in the usual way. The thread had a tool to back up the nv_data bin. I think that's how I remember it

Thanks for that. Nice to hear that its not some strange security trigger or me going crazy then. If anyone knows the post that sawdoctor is referring to I would love a link.
I am very hesitant to do any kind of custom ROM flashing without an IMEI backup. From what I have read, if I lose my IMEI data its possible that even flashing a factory image wont fix things is that correct? Even though I do have a Nandroid backup I am not 100% sure it contains the IMEI data in it because of the absence of a file. : \

I m using this thread to backup efs.
The only method works to back up N7105 efs.

Thanks for confirming this. Was not sure if this would work for phones with the nv_data file missing. In the guide it does say "This will back up all your phones NV Items and save them to the QCN Backup File.". And theres a total absence of NV files on my phone. lol. But being its confirmed working by people I can only assume its looking in places that I cant/have not. Will test it after I have done all my various RL tasks for the day. If there is other people who have done a full backup and restore with this method and confirmed it functional I would love to hear from you.
Cheers.

7105 nv backup
The 7105 is not like the 7100 model it has a completely different
frame behind the screen
a different plastic intermediate case
a different mainboard
the 7105 device also stores data in internal NV RAM which is not accessable easily
it is thought that the Qualcom tools or NV-Ram backup tools can backup these internal areas
BUT
it is possible to erase or damage the NV-Ram so that you cannot talk to the Ram to RESTORE the data
even when you have a backup
as a result even when you have a full NV Ram backup there is not yet a solution which
will ensure that a damaged NV-RAM area can be 100 percent sorted back to working if you are unlucky
just make sure you NEVER clear NV-RAM from Odin on a 7105

This is the kind of thing I was afraid of. Thanks to fibreoptix for sharing that. I am just glad that there is some method for backing it up. No idea how these chip-specific tools get released to us because I have no doubt its not intentional. I am glad that there is people out there willing to take them out of the OEM space and pass them to us so we can protect ourselves from disaster.
I dont know enough about this stuff to do anything but make assumptions, but I assume that this NV RAM that you mention is physically located in the SOC and not on memory anywhere. So I doubt that this will ever get any easier in terms of achieving a backup on any upcoming devices either. I guess all we can do is pray that various individuals keep releasing these OEM tools to us. In terms of the RAM becoming physically inaccessible and broken its not that concerning providing you can flash back to stock and get a warranty job.
