Hi,
I'm running CM 10.2, and using TWRP 2.7.1.2 Recovery.
I think that when I was "cleaning" my phone prior to installing ROMs, I was a little too thorough, since based upon my poor 3G/4G performance/coverage, I guess that my PRL list is pretty minimal.
I gather that the procedure to fix this is roughly:
Make a Nandroid backup from Recovery
install a stock ROM
update to latest PRL
Restore the Nandroid backup
But I don't understand some of the fine details. In particular:
When preparing the Nandroid backup, what options does one use?
What sort of "wipe" if any, does one perform at this point prior to installing the stock ROM
HOW does one install the stock ROM image asanti_c_sprint-user-4.1.2-9.8.2Q-122_XT897_FFW-5-6-release-keys-cid9.xml.zip ?! It looks a little different than custom ROMs
After updating the PRL, what sort of "wipe" should I perform prior to recovering from my Nandroid backup? I'd like to be thorough, but not so thorough that I wipe out the PRL update. Where does that PRL list reside?
Does the Nandroid backup include the ROM images which I flashed? (CM 10.2 and the corresponding GAPPS) If not, then in what order does one flash ROM images and recover my Nandroid backup?
TIA ...
1. Doesn't matter, whatever you feel you need to restore. At a minimum backup system. Backup data if you want your data saved...
2. None, if you use RSD Lite to reinstall stock it will wipe ALL. Everything will be back to stock (including recovery).
3. RSD Lite.
4. PRL List should not be wipe-able from recovery, AFAIK. Factory reset should be fine.
5. The backup will include whatever was currently running on your phone - CM, gapps, any installed applications, etc. Simply restore your backup, no order of operations here. Of course you'll need to reflash TWRP in order to restore your backup (again, flashing with RSD Lite resets the ENTIRE phone, including custom recovery).
If you had taken a backup of the stock setup, you could skip the whole RSD Lite crap and just restore your stock setup, download the PRL, and restore your CM setup. For future reference, step #1 after getting custom recovery is always always ALWAYS take a backup of your working stock setup before making any other changes.
Thanks for your detailed response. As a Mac user, I believe that RSD Lite isn't a viable option for me. I do have another Motorola Photon Q phone with the stock ICS image, but don't know whether that is helpful in this case.
I guess that I need a strategy using adb, fastboot and TWRP. Thanks ...

The stock backup from that other Q would work. Just do a factory wipe and restore 'system' only from that other Q.

1. IMHO, you should extract necessary settings or data and restore to your new rom. You can use AppExtractor
2. No need to delete everything before restoring
3. Your choice. There is touch version out there. Try and love it

Thanks for your reply i really appreciate it.
i was saying that if i wana go back to my stock rom (original rom) wich is not rooted can i restore it using CW?
if i flash back to my stock nandroid backup using CW my phone will not be rooted and it will restore the default samsung rom?
its just my theory though i haven't tried it yet i`m asking question like this for my future reference
Well...
Yes your device wont be rooted and will return to the stock rom.
Since the nandroid backup copies the whole partition. just like Norton Ghost does on the pc, so your phone will just go back to its exact status it was at that time.
You wont need to wipe user data/factory reset, because of the data partition being restored by CW.
Well you are asking for a recovery. How did you make a nan backup if you have no recovery?
Or you used the stock one? if you used the stock one, aren't you able to use it to restore?
Or do you want a new more powerful recovery?
As in the previous post they mentioned, use the one you like, with the most options
A little click to the 'Thanks!' button if I helped you
Finally was able to succesfully root my phone last night, and now I am wondering how to actually flash a custom ROM. I figured I'd start with Cyanogen since its the most popular and seems like a good starting point. So, I have a few questions.
1. How do I install the custom ROM? (Cyanogen in this case) Also, is this process the same regardless of what android version I have? (I'm currently on the stock 4.1.1 OTA)
2. Should I install a custom kernel? If so, is it the same process? Also, is my data wiped just the same as with flashing a custom ROM?
3. If I make a backup with Titanium Backup, will I simply be able to access/redownload my app data it if I redownload Titanium after I flash the ROM?
Any and all help is appreciated!

I'm sure everyone has their own advice, but I would say first thing you'll need is ROM Manager
Download the ROM you want and place it on your sdcard. Use Titanium Backup to backup your applications, and then restart your phone in Recovery Mode. When in recovery mode, make a backup by going to "Backup and Restore" > backup. Then do a factory reset and wipe your cache. Install the new rom and enjoy the addiction
Also...be careful making sure that any kernel flashed is compatible with the ROM you are flashing. If not you can brick your phone.

This. And read, read and read.
And backup your imei.

If i clean flash a new Rom but restore the data part from a backup i did earlier from another rom from recovery will it work? Im using TWRP recovery.
ive always had mixed results on this. if youre going from a TW ROM to an AOSP or AOKP rom, likely not. If you use TiB and backup your apps and their respective data, and restore them via the same method, that 99.9999% of the time works
Hello forums,
I have a rooted One running the latest official update version 44S with TWRP recovery. I am interested in flashing an Android Lollipop port (the one made from CM12 dailies). If I don't want to lose all my app data permanently (I know several resets and erases are necessary to swap ROMs), how can I back it up and then restore it once I've upgraded? Can I keep a backup of my current ROM/apps through the various resets necessary (just in case of big issues or bootloops)? FYI all my backups include system and data, but not cache.
Thanks to any help in advance!
If you're only backing up system and data, your phone will never boot when you restore the backup, you need to backup boot as well. You should always keep at least one backup on your phone at all times, just in case things go wrong. Unless you wipe your internal storage (which you don't need to do) you won't lose your backup. In regards to your user apps, just use Titanium Backup to back them up and then you can restore them after flashing a ROM.

Due to problems with Google Services on my rooted Galaxy S5 (SM-G900F) I opted for a reset from TWRP and it returned to a condition where after some initial screens it was just stuck at "Checking for Updates" so I went back into TWRP and told it to wipe the other partitions. Whoops - now I have no OS (I was sort of assuming that the factory reset OS was somewhere else)
Which is the stock ROM for my Region - UK, unbranded - where do I get it from and how do I load it using Odin and/or TWRP?
TIA
Hello,
Did you make a nandroid backup of your stock ROM or a nandroid backup of a custom ROM if you installed one? If you have a nandroid backup of either of those then you can restore them in TWRP by choosing the restore option and then your nandroid then swipe the slider at the bottom of the screen. If you installed a custom ROM at any time before this and you still have the ROM file then you can reflash the ROM and Gapps.
If you don't have a custom ROM stored anywhere but can still get to recovery, then you can download any of the custom ROMs compatible with your device and a Gapps package that matches it and put them on your extsdcard then boot to recovery and flash the ROM and gapps, do the normal wipes in recovery after flashing, the normal wipes(wipe data/factory reset, wipe cache and wipe dalvik cache), DO NOT CHOOSE THE ADVANCED OPTIONS THAT LET YOU WIPE PARTITIONS.
Check this thread to see if it is your stock firmware, it SHOULD be but double check first, it also has instructions for rooting again and installing recovery.

If that doesn't work then go to Sammobile.com and search for your stock firmware by using your device model number.
The firmwares can sometimes be found at samsung-updates.com also.
Find the right firmware for your exact model number and flash through Odin.
For further assistance, post your question in the forum linked below.

Good luck.

Sadly not - wasn't expecting to need it, thought it would revert to factory default - I have Titanium backup of apps and data.
I am hopefully a few minutes away from downloading the stock ROM and hopefully can reflash that using ODIN.

Making nandroid backups in recovery is the most important and valuable function of custom recovery, flashing ROMs is its' secondary purpose Android is not like PC with a recovery partition that restores a factory IMG, on PC that factory IMG is stored in a recovery partition. The factory reset feature in stock android does not restore an IMG, it deletes all data from the user partition and leaves everything in system partition the way it is, if you delete a system app and then do a factory reset then you will still not have the system app that you deleted. Anything you modify in system remains the way you modified it if you use the factory reset option. You should only use the factory reset in recovery, not the factory reset in system settings when you have a rooted device with custom recovery.
I'm sure that when you found the recovery, the directions had to have mentioned making a nandroid backup of your stock ROM before flashing anything, your present situation is why you do that, so that if anything goes wrong then you can easily restore to the one ROM that you know for sure works with no issues.

I installed the TWERP recovery as part of the rooting operation and I didn't pay any attention to the backup option - I thought that's what Titanium did.
I am learning and will make sure that I take a Nandroid backup once I have it back up and running. Life would be so much simpler if only Samsunng didn't stuff their 'phones with bloatware that can't be deleted in stock mode.

Titanium backup can only backup data that you installed or downloaded, it does not backup anything that comes on the phone itself, that is what custom recovery is for.
When following guides to mod your device, read and understand ALL instructions before you even make the first move to touch your device. Get used to being thorough about reading and understanding first or you'll end up in a mess, possibly even hard brick your device, all it takes is one wrong move. Not all mistakes are fixable with android devices.
