You should Odin back to stock! Check the dev section. I'm sure there is a thread with stock rom and recovery.

Odin would be the only way. Correct.

Are you able to nandroid through cwm recovery?

Nope i cant i dont even know how this problem came along i was using a stock root then i decided to install CM 10 and when i tried to back it up i started getting this problem :l and i dont know how to return to stock i downloaded that SAMSUNG GALAXY S3 TOOLKIT would that program be able to return me to stock unrooted.

Can someone point me to a link that will help me go back to stock unrooted. Like the phone was straight out of the box?????/

You should do your backup directly in CWM and not ROM manager. Go to backup then back up in internal storage. I'm on touch 5.8.4.5 and back up directly in CWM then rename manually in Rom Manager. Just download a stock rooted ROM and flash it in CWM. Can you mount sd card in CWM? Just download a ROM then mount sd card and copy then flash after will ng data and formatting system and wiping caches. I would personally Odin back to a stock ROM, its easier.

It should of unrooted you. Try down adding Titanium backup or a app that requires root and check if you don't have root.

Try to back up to your internal sd card instead after that error message by using the backup and restore menu in recovery mode. That happens to me when i try to use the ROM manager backup method because my ext sd card is full

You can have custom recovery and not have root. Go to your app drawer and if SU or superuser is not there then you are not rooted.

Okay so i flashed stock recovery via oden then i flashed the stock rom .tar file via oden. then after my phone was back to stock i re-rooted it and flashed cwm my phone is no longer getting that message but it still isnt backing up to the sd card ??? can someone plz help me

If cwm is giving you a hard time try twrp. That's another alternative recovery we have. Maybe that will do the trick.

That are parts of your nandroid backups.

This is all the data and info that you've backed up using Clockworkmod recovery. This is one of 6.0.1 "update". Apparently, this will save you some storage when you backup up multiple ROMs. Don't delete it, or the restoring would not be successful. If you want to delete a backup, either delete using file explorer or ROM manager. Then you reboot to recovery. Then the recovery will delete certain portion of the data in blob file that matches the deleted backup.
personally don't like it, so I use TWRP
Hope this answered your question

Will convert to twrp. Thanks. Just didn't know if that massive file size was normal.

I didn't force you to convert to TWRP by any means... If you like CWM, just use older version. Also that is normal
Another thing I should mention, TWRP cannot restore CWM backups and vice-versa.

Or use one of the newer builds like 6.0.1.2 or 6.0.1.3 and choose to use the old .tar method.

Well I don't have CWM anymore, so didn't know that

Nobody forced me into anything. I've been thinking about switching to twrp for a while now anyway. I prefer their UI to CWM. I've just used CWM since my days with my Droid Inc and EVO. TWRP was incredibly easy to convert to and I am currently making twrp back ups on both my Galaxy Nexus and my Nexus 7. I didn't have any old back ups that I couldn't live without in CWM. Now when I get rid of the CWM I can just delete the blobs folder and get that 11 gb back right? Plus I'm looking forward to using my USB OTG to store my backups. They have always been the one thing that has dominated my storage.

If you have backups for TWRP. CWM folder is not necessary. Just bare in mind that this folder includes all your CWM backups.

can't seem to get back to stock (3.20.401.1)

HI,
I have a europen (international) htc one x 32gb, currently running miu 3.5.7
i want to get back to stock and I was looking at the threads about how to do this using a ruu but I'm not sure how to continue:

i first wanted to use a nandroid backup but the file here is not on dropbox anymore:

but it is only 36 MB and there is no executable file in it ...
is there another ruu i can use or another method to get back to stock?

That ruu is only an ota which stands for over the air update, I can try and find the right one for you
Edit: I don't think there is an ruu for your version so I think the only way to get back to stock is a nandroid which is not on dropvox anymore as you said.. Mr hofs uploaded it I believe if you can get in contact with him he might still have the nandroid for you

I just wanted to ask if it would be ok to flash the 3.14 recovery
one more question:
I used getRIL and it says this:
RIL: unknown
baseband: 5.1204.162.29
is this ok/normal or is it rom specific (miui)?
and by flashing this backup etc, does this also get the original kernel etc?
my kernel now is 3.1.10n3okernel_v33-gf404256-dirty
so in other words: is everything back to the original and can i be sure i have the right radio etc?

Restore the nandroid and also flash back the boot.img from the nandroid backup. Then you have stock kernel + modules.

hi,
i tried restoring your backup but it saus: error while restoring /system
i downloaded your file, put it in the backup folder, flashed boot.img and erased cache, then restored back-up

Flash also the recovery.img to be sure you are using the same one as it is made with
And also enter mounts and storage and format all except sdcard

Flash the recovery.img from the nandroid backup folder, flash the boot.img from the backup folder. Make a full wipe
Factory reset
Wipe cache partition
Advanced-wipe dalvik cache
Mounts & storage-format cache,data,system
Then restore the nandroid backup and THEN restore the stock recovery i gave you in that separate link !

I did a restore of my One-X to stock rom according to this tutorial.
http://design-extreme.net/restore-htc-one-x-to-stock-rom/
This all went well and without problems. The RUU I flashed is this one.
RUU_ENDEAVOR_U_JB_45_S_HTC_Europe_3.14.401.31_R_Radio_5.1204.162.29_release_302015_signed
When I now startup the phone it all works perfect. Then the phone says there is an OTA (to 3.20 I believe)
I download and install the OTA and the phone restarts, but after restarts the phone's touchscreen does not work anymore.
I solved this for now by installing the 3.14RUU again, then it works again. But of course I would like to be able to install the OTA's
To me it sounds like a driver problem in the new version that prevents the touchscreen from working. You or anyone else have idea how to solve this?

Flash the recovery.img from the nandroid backup first. Then make a full wipe and restore the nandroid. That will solve the restore error.

[Q] I got sent an unlocked M8, how to go to default install?

Hi,
Rogers sent me a refurb M8 but the problem is it's unlocked and it shows these at the startup (at the end of the post).
How can I restore this to default locked or unrooted version where I don't see this kind of stuff? I just want the default setup. The phone asked me to install the newest android and I accepted but it still shows the same startup which prevents installing the update automatically as it would otherwise.
I went to restore and I chose this update (I think) myself and now after the install, my phone is stuck in this looped animation which starts with "google" and then you see these 4 circle like shapes moving into the center and away forever. What should I do?
Thanks.

Thanks I could do that but they sent this to me accidentally so I want to keep it. My old phone is M7. But the problem is I don't know what I need to do.
I followed the method 2 here but I don't know how to initiate the custom rom installation, it doesn't start:
http://www.droidviews.com/restore-sprint-htc-one-m8-to-stock-rom-with-ruu/
Choosing HBOOT, shows a different menu, doesn't do anything.
Any ideas?
Thanks.

That is not a custom ROM installation, its the RUU for the Sprint variant.
Its a good thing it didn't start, as the Sprint and Verizon versions are CDMA, and installing anything for those versions might brick your phone. I strongly recommend you not follow anything from that webpage.
Also, on the hboot screen, does it say S-on or S-off? What hboot number?
You should go to the following thread, get the nandroid for Rogers, flash in TWRP. Then get the corresponding stock recovery and flash in fastboot: http://forum.xda-developers.com/showthread.php?t=2701376
You will also need to install fastboot, and I think this is probably the easiest and least painful method:
http://forum.xda-developers.com/showthread.php?t=2588979
I can understand why you want to keep this phone. But to do what you are asking, you will have to be patient and do some learning . . .

Thanks alot, I don't mind some learning but I have a week to do this and then try out the phone so I can tell if it works. So then I can return my original phone. Otherwise they would charge me the full price of the phone.
Ok so on the hboot screen, it says s-off.
Hboot version is 3.16.0.0000.
So nandroid is someone's backup right? How do you flash in TWRP? I think using Hasoon2000s app, I installed ClockWorkMod because that's what I see now.
You mean installing fastboot on my PC? Because I think I did that as I can use that command and my phone boots.
Is "1.12.631.17 - TWRP" nandroid a good one from the first link you posted?
Lastly when I do this, it will basically have this OS, right? But will the TWRP, etc stay? Because I thought it will be like formatting my PC where everything is gone and all I have left is factory stock sense.
Thansk again.

Correct, its a nandroid somebody else made. Its meant to be "stock" and for anyone to install (assume it contains no user data). You install by placing the backup in the appropriate folder (if TWRP, find the folder TWRP on the internal storage, and you will see subfolder called "Backups" and inside a folder with some random looking letter and numbers (mine says HT. . . .). Its inside that folder, you want to save the downloaded nandroid file.
Once the file is saved to the right place, TWRP will just think its a backup you made. So select "Restore" in TWRP and select the appropriate file.

If your recovery is CWM, select the CWM nandroid. If your recovery is TWRP, you need to select the TWRP nandroid. The 2 recoveries work differently, so you can't restore a CWM nandroid with TWRP, or vice versa.

If you have fastboot installed on your PC, then you are all set. I just assumed you did not.
Fastboot is only needed to install stock recovery (after restoring a nandroid), if you want a truly "stock" install.

Its the nandroid that has the stock Rogers software, yes. As mentioned before, you need to have TWRP recovery if you want to restore the TWRP nandroid file.

You will still be on custom recovery. The nandroid doesn't include recovery.
It not like formatting a PC as you describe; because on the phone, recovery and a lot of other things (radio, bootloader, and more) are on separate partitions. A nandroid restores the system (OS), data (user data) boot (kernel) partitions. The other partitions are left untouched.
If you want to restore stock recovery, you can do that as well as shown in the link I provided (same thread as the nandroid backups).

Wow thanks alot man, I understand it alot better now.
After I do this though, and the phone installs a new update for me, will I be able to install it?
Because right now when that happens and I say "install now", it restarts and shows TWRP but from there I don't know how to install this update. I am used to selecting "install now" and the phone would automatically install it at startup. I want to have this behaviour if possible.
Also how can I restore the stock sense after restoring the nandroid?
PS: I just restored the nandroid but when the phone restarted, I see my old OS, i.e. same wallpaper, same apps I have, instead of seeing the startup wizard. I assume I won't see the startup wizard but shouldn't it be a brand new OS like you said? So it didn't work?
TWRP said it restored successfully in 126 seconds.
Thanks again.

Any ideas?

Which nandroid backup did you download? You must have also the same recovery. But let's take it one step at a time. Let us know which nandroid you downloaded and we will take it from there.

Can you open the zip file and tell me a bit the folder structure? You will need xopy this folder to your external sdcard and from TWRP you go to Restore and select the folder from the sdcard to restore the nandroid.
It's not a flashable zip

Thanks I am not home right now but it had a few files. I extracted the folder to my pc and then copied the folder. I saw it in twrp and then it restored it correctly. I mean I saw the nandroid there in the restore list. So I did that correctly right?

What does ROM version say?

Sorry for the late reply, I just got my phone. So it says:
android ver:
4.4.2
HTC Sense ver:
6.0
software number:
1.12.631.17
Is this correct?

Yes this is correct. Now if you flash stock recovery 1.12.631.17 you are stock and ready to receive OTA from HTC

Thanks, how do I do that? Do you mean selecting factory reset from the boot menu?
Also if nandroid restore worked, why do I see my apps and wallpaper, etc? Is this normal? Sorry for being a noob, I just never dealt with this.

First of all factory reset...It will reset your rom and you will be completely stock ready to setup like new.
Then to get rid of the custom recovery, download the recovery from here:
http://d-h.st/sQF
Paste it in your fastboot folder and reboot to bootloader.
then run this command.
fastboot flash recovery stock recovery 1.12.631.17 recovery.img
Reboot and you are set

Thanks alot man, I will try this tomorrow and report back asap. But by fastboot folder do you mean the one in the Android folder or somewhere else?
C:\Users\username\AppData\Local\Android\android-sdk\platform-tools

[Q] Reverting to Stock GPE Kernel without using an RUU?

Hey guys,
I'm currently on a fully GPE converted phone running stock Lollipop 5.0.1.
I have S-Off, root, TWRP and Xposed.
I'm planning to flash the Quantum kernel on my device mostly to get KCAL support (LCD color switching), but also for the supposed battery improvements.
I'm obviously going to take a TWRP Nandroid backup prior to flashing the kernel so that I can restore back if something goes wrong. But what I'm wondering is, if I decide I actually want to go back to the stock kernel at a later date (say in a month), is there any way to flash just the stock kernel or back up my current one? I can't seem to find a copy of a stock GPE kernel, can I compile it myself or something similar? I'd prefer not to have to do a TitaniumBackup and use an RUU since that's such a load of effort.
I'm a software engineer so no need to sugar coat any technical details for me.
Thanks!

Download the GPE ROM, unzip it, and look for the boot.img. That's your kernel.

Thanks. Could I just restore my TWRP Boot backup for the same effect?
Otherwise, in terms of flashing the boot.img, is it just a "fastboot flash boot boot.img"?
Edit: Also, slightly off topic but how does a recovery flashed ZIP know to replace the kernel and not flash to /system instead?

You could restore boot from your backup. I've never done it myself, but I'm sure it would work fine.
Fastboot flash boot boot.img is correct.
The zips are broken up into appropriate folders; be it ROM or backup; that are directed to the proper partitions during the flash in recovery. I've never delved into it too much, but I'm sure they have something like [flash-boot] [/flash-boot] written into it.

I just unzipped the Quantum flash ZIP and noticed that it also seems to flash a bunch of files to system as well as to boot.

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

Would I be correct in assuming therefore that I would need to flash both boot and system images from the GPE RUU to get back to the stock kernel? To save having to re-flash system could I just open up the system IMG and extract the files that were replaced by Quantum?

Do a full nandroid backup and, if you wanna go back to what you had before, restore it. As you're correctly found, there are some system modules required to work with the kernel so just flashing the stock kernel might not work

Was hoping I could get back without the full backup. I've done the flash now and let's say for example if I want to switch back to the stock kernel in 1 month's time, using my nandroid backup would lose me a lot of data, I'd be better off just taking a Titanium Backup, flashing the RUU and restoring, but that's a massive pain as well.
Would my idea of manually replacing the system partition files that Quantum modifies with their stock variants, or deleting them in the case that the stock variant has no such file, work?

Yes, in theory, so long as you can get them all. Remember a Nandroid won't touch your personal data but might affect any app data but it's ALWAYS recommended to make a backup so at least you have something to fall back in should the worst happen

Don't worry I definitely took a backup, and I'd restore if things had gone wrong immediately (boot loop, etc.)
My concern here is more so for what happens if I decide after a month or so of usage that actually I don't like Quantum and I preferred stock (battery life worsening, etc.)
Thanks for all the help.
