Hello,
I downgraded my N4 from CM 11 to 10.2.1. The phone boots, optimizes apps but doesn't complete the boot process/starting apps and I'm stuck in a bootloop. Should have done my research before downgrading! What do I do now? I have a nandroid backup from CWM on an external disk but I would prefer not wiping data. Would flashing the 10.2.1 kernel then the 10.2.1 ROM work? How about reflashing [dirty] the CM 11 ROM? Any suggestions or guidance would be appreciated deeply. :crying:

Turn off the phone then boot into recovery and then do a factory reset (aka: wipe) and then flash the ROM that you want to downgrade.

Is there no other way but a wipe?
Also, if I may bother you with some questions:
1. Can I do an adb backup in fastboot mode?
2. If I do a CWM backup and then a wipe, will the backup be erased

When you do a factory reset, it won't wipe your nandroid backup. You can do a nandroid backup via adb commands, but it is easier to do it in recovery.

Thank you so much. When I do restore nandroid, is there any way I can selectively choose what segments of the backup I want. Eg. I do a backup NOW from recovery (CWM), wipe, install ROM and then restore selected files or apps ie I don't want the kernel etc. Is that possible?
I flashed CM11 once more, cleared caches, and booted..works fine..I'll backup what needs to be backed up and will do a wipe tomorrow UNLESS I get used to the hideous esthetics of Kit Kat in the interim.

Hi all,
So I'm facing a problem with my Defy after flashing some ROMs, as detailed in this post.
Since I've made Nandroid-backups when everything was OK, my natural answer was to restore the phone to a previous state using it.
But for some reason after restoring a Nandroid (I've tried with both I have) my phone stucks with the Google logo and never finish booting...
Those are the steps I follow to restore a Nandroid:
1. Boot into Recovery Mode
2. Wipe data/factory reset
3. Wipe cache partition
4. Wipe dalvik cache
5. Restore system & data (choose nandroid by date)
6. Reboot system now
Am I doing something wrong? Why can't I restore my phone to a previous date?
Any idea is greatly appreciated...
You might have flashed gb kernel ROMS as well. Probably now you are coming from a GB kernel build to a froyo kernel build.
You need follow these steps, restore system+data, boot, devtree, and optionally recovery. Check if you have boot.img, devtree.img files in your nandroid. You should use cwm recovery which has these options to restore, they will present in Advanced restore.

Thank you. I would've tried this. But yesterday night I did a full SBF so that I could restart using the phone. So I've lost access to root and CMW. Will bring those back when I have a chance and, then, ROMize it all over again...
Cheers.

Try using the normal option after the restore in the boot option in bootmenu rather than 2nd-init
Hi,
I have flashed a new rom and i wanted to restore my data via twrp.
It was successfull, but my N7 was not able to reboot, because just booting and it havent done anything.

You're confounding variables here... you're trying to use TWRP like Titanium (apps/data).
TWRP (like CWM) is a MONOLITHIC backup system, pretty much everything gets restored. Titanium is GRANULAR... and selected apps/data are restored WITHIN the ROM you've just flashed... not OVER THE TOP of the ROM, as you've just attempted to do... which will cause no end of problems.
--------
Here's what I would do.... restore your NANDROID backup as normal (factory reset, etc.)... Get TITANIUM from PlayStore. Backup your apps/data using that.
Flash your ROM... restore your apps/data using TITANIUM.

So I was running CM10.1 nightlies with Franco Kernel and decided to make the jump to CM10.2. The ROM and gApps flash went just fine, but like a dummy, I flashed the version of Franco kernel that I'd been using before, which I guess is not compatible with 4.3. The phone seemed to be softbricked and would just hang at the Cyanogen boot animation. I can get into recovery and I've tried to reflash both CM10.1 and CM10.2 - both hang at the boot animation. I can go back to my stock backup just fine, but then when I try to flash CM again (either version), I have the same hanging problem. Does CM store like a memory of the kernel that you have flashed and try to revert to that? Why can't I flash CM again once I've gone back to stock (and the stock kernel)? Would reflashing the stock image fresh (rather than using a TWRP backup) change anything? I'm pretty inexperienced with this and would appreciated any help. Thanks in advance!

Just to be sure how much juice was left while you were flashing CM rom?? Reading your problem I would suggest you to do a fresh Stock image installation and then try flashing CM 10.2.
Have you tried restoring your NANDROID backup, if you made one??

I have restored the NANDROID backup successfully, but unfortunately I was lazy and only have the backup from when I first got the phone.
I backed everything up with Titanium Backup right before I tried to flash CM10.2. If I do a complete stock reflash, do I lose all the data I backed up with TB? I do have some app data that I would really like to keep if possible.
One other resort I thought of was flashing a different custom ROM (Paranoid Android maybe?) and then restoring my TB backup. Would there be any reason that I shouldn't be able to reflash CM after I've restored the stock NANDROID?

Try this.
As you are able to go in recovery,
Wipe cache , dalvik cache, system, data install PA 3.97 flash pa_gapps then supersu v1.51(for root,also enable app+adb from developer option)
wipe cache and dalvck again and reboot..
P.S : Charge your battery first to 80% minimum and flash the rom.
If the above doesn't help,
Backup all you valuable data into pc, backup app+data through TB move it to pc and flash the factory image through fastboot.

I ended up flashing the stock image and completely wiping all data. I then tried to install CM10.2 again and it still hung at the CM boot animation for about 15 minutes. It shouldn't take that long to flash, right?

Did you use the Franco.Kernel for the JSS build?

I just rooted my phone yesterday and I tried to delete a TWRP backup that was on my internal memory. I was unable to find out how to do it and set permissions in TWRP, which caused my phone to start booting with unable to start messages and a black screen. I tried restoring a backup and I wiped and restored, both have still same issue.
So at the moment I can start TWRP or factory reset, but as of yet, I cannot restore my backup.
When I backed up the phone I didn't select everything, I left out data.
Since you didn't backup your data, they are a few options. Wipe dalvik and cache from recovery, dirty flash a rom, clean flash a rom.

I was using an old version of twrp. I updated to 2.8.6.0 and it all works now, thanks.
Hi i tried to restore my Dirty unicorns backup and now i am stuck at the google screen. I booted to twrp and tried to erase the efs but it didn't work, still stuck at google screen. Also if I recollect i did not backup and restore the efs partition so i don't know what else it could be i did backup the vendor and the rest. Using twrp 3.1.0.0

To backup your current setup:
Boot
System
Data
Vendor
Is enough
Just in case: https://twrp.me/faq/whattobackup.html
If you switch to another ROM, wipe the above + dalvik/ART cache, data and cache partitions.
Then flash whatever you want with matching vendor. Redo the complete wipe above and restore your backup if you want to switch back. Backup your EFS at least once and keep it in a safe place...
Hopefully you won't end up bootlooping anymore! :good:
I have never succussfully restored a nandroid backup on this phone with any version of TWRP. I don't even try anymore because it's just a waste of disc space and time.
