I noticed in TWRP 2.5 that there is the option to backup/restore 'Preload'. I have also read that the ROMs based on TMo 4.1.2 need preload working properly to boot, unlike previous ROMs. Should that option to include it be checked when backing up and restoring the stock 4.1.2-based ROMs?
I've also noticed that the the Preload size is 0 when backing up other roms in TWRP, so I haven't concerned myself with it. Before TWRP 2.5, I knew nothing of preload (I guess I still don't really know anything). Any thoughts?
Well, I guess I'll find out what to do by trial (and error?). I backed up JMT JB3 (including preload) to flash the Koodo update and run it for a while. I'll restore it later on and see how it boots.
I'm not sure how it works. I'm on JMT3 myself right now. I used ODIN to update to the official release when it came out, and it was doing fine, but I wanted to try some of the custom ROMs out there that are based on it. I was rooted with CWM, and did the usual backup that has worked since I can remember. I don't remember what ROM I tried next, but I didn't like it much, so I restored my back up. It restored correctly, or so I thought. After some use I started getting FC here and there. I couldn't fix it, so I did a factory reset from within the phones settings, not through recovery. As soon as it tried to reboot I kept getting a boot loop. I never was able to get it booted. I was able to boot to recovery, flash cache and wipe scripts that were recommended, and flashed JMT3. All is good now. I know trying a cache wipe or factory reset through CWM won't work since I tried it before, so I didn't even try it for this one.
So long story short I don't know how CWM (or any recovery) handles the preload. All I know is the scripts work to flash clean, or wipe cache/dalvik/fix perms, but I haven't gotten them to work after restoring a back up. My thinking is to be careful until someone figures it out because I don't think backing up will help if I ever need to. I'll have to start fresh each time I want to flash anything.
Here are the scripts I'm talking about: http://forum.xda-developers.com/showthread.php?t=2235141
Thanks for sharing your experience. I have those same scripts handy - had to use them when I flashed JMT3.
If or when I restore, I figure I'll wipe my current preload and restore the preload in my JMT backup, then flash the Infamous cache wipe script (or equivalent function in recovery if TWRP develops something similar). I'll post again to share my results when the time comes.
I ended up wanting to restore old stock 4.0.4 in TWRP 2.5.0.0 recovery. Part of me wanted to do it just so I could test the backup/restore of the preload.
I first backed up my current rom (stock Koodo/Telus 4.1.2) with the cache and preload included. I then wiped data, system, caches and preload, and ran the restore of my old backup. The 4.0.4 booted just fine. Once I was done checking for the info that I wanted, I went back to recovery and wiped all the same stuff (everything except internal and external SD) under advanced wipe options. I then restored my stock Koodo/Telus 4.1.2 backup. It seems to be running fine now although I haven't experimented much to test for any FCs. It didn't seem to have any issues booting at least.
I may have been doing some excessive wiping - I assume restoring a partition also formats it before overwriting it. I'm not even sure I needed to wipe anything to restore 4.0.4, but I didn't want a preload (110 mb) causing issues in a rom that doesn't need it at all. In any case, I know what can be done to avoid issues restoring stock 4.1.2, although I'm still not sure what needs to be done to avoid issues.
You did it exactly right. When using a 4.1.2 Samsung rom, be it custom or stock, and backing up or restoring; the preload folder is just as important as data or system. Basically the point of the preload patition is to get the system partition to fit. By symlinking the apps from preload to system Samsung has saved room and allowed a bigger rom to work on our hardware.
As an example, I am on TWRP 2.4.? and cannot backup preload. When I tried a different rom, then went back to my backup I had FCs like crazy. Because I had used the Infamous wipe script it had wiped the preload folder but there was nothing to restore to it from my backup. I had to reflash the rom I was using (really I just wanted the preload folder installed) and then restore my backup to get it working.
I hope all this makes sense. I'm going to Twrp 2.5 so I can backup my preload folder (when I stop being lazy).
Thanks guys.
Long story short, I've spend the better part of 2 days trying to get my phone to working order.
I tried to flash the stock 4.0.4 rom into my phone. After I did that, the radio stopped working so i wanted to go back to my previous All-star-v7 rom that i had backup in the external sdcard.
When I was installing 4.0.4 i had to switch from CWM to TWRP to get it to install. I switched back to CWM using ODIN but now when i try to wipe the phone so i can restore a backup, it hangs up on wiping /cache and if i try to restore it hangs up on restoring cache....
What do i do? I had used the infamous super wipe and cache wipe to get the phone into 4.0.4 I think i messed up something because of using those...
update: Strangely, I can restore a backup of 2.3.6 and even though it hangs on restoring /cache. I restart the phone and it boots up to it. I also find that google play is unable to update any of my apps, it looks like it's because of the corrupted /cache. how would i fix it?
update2: i used odin to flash into TWRP 2.6.3.1 and did a cache wipe and it's stuck at "unable to open '/cache/recovery/.version'. anyone know how to fix that?
Hi,
I was frustrated with the delay in T-Mobile's release of KitKat for the GSIII, so I decided to root my phone last night in order to try flashing CM11 on it. Rooted my phone with Towelroot, installed ROM Manager and CWM, and created backups on Kies and through CWM. Then I proceeded to do data wipe/factory reset, cache wipe, and /system format. Tried to flash CM11, but got a status 7 error.
I freaked out, so I decided to restore everything from the backup I'd created. Restoration seemed like a success, but now I get the error "Unfortunately, the process com.google.process.gapps has stopped" in an endless loop, and it prevents me and any apps from doing anything. I tried clearing dalvik cache in recovery, but the problem still persists. Read on a few threads that I should flash to stock firmware via Odin, but I'm currently on a macbook, so I can't install it.
tl;dr - Prepped to flash CM11, reached status 7 error, got freaked out, and did restore via CWM, only to get infinite loop of gapp crashes. No access to Odin or PC. Not hard bricked or soft bricked, but essentially useless phone. Help? );
if you can still get to recovery, download latest gapps and flash that
Did you factory reset before or after you restored your back up?
Yeah, I've tried flashing gapps--no avail.
And yeah, I did factory reset/data wipe, cache wipe, /system format 3x each before attempting to restore. Was that wrong? /:
Try to factory reset again

If I'm not mistaken, there is some device ID that will change each time you flash a new rom. It may be something to do with this ID not matching the one in the restored data. Purely a guess but seems logical to me.
Anyway, factory resetting will most likely solve this for you, but I wanted to add that except in certain circumstances, you shouldn't ever manually format /system. (and one format on any partition is sufficient. There shouldn't be any need to format multiple times). If you format /system, you are wiping the O/S off of your device. Then what happens if you have problems flashing a rom, or firmware? I've seen it happen many times and I often end up spending a couple of days working with them just to get the thing to boot up again!
When you flash a rom, the first thing it does is format /system. So there is just no need to do this manually. At least if the rom fails to flash (such as failing the assert checks), youll still have something to boot into. Hope this helps in the future!
I have had the exact same issue. I have a Samsung note 2 N7105. I rooted made a backup in CWM and flashed ditto n3/s5 rom made another backup in CWM. No issues. Got a bit cocky seen as it was my first time doing anything like that. My next adventure was to try a custom kernel (agni). This didn't go so well, so I tried to do a restorw to my working backup of ditto n3/s5 rom through CMW. restore went smoothly and the phone booted. once I opened the lock screen I got the gapps error as described. I had to do a factory reset to get the phone working and then re-flashed ditto n3/s3. I've since flashed other roms and when ever I try to do a restore, I get the issue described. Note I am using the latest CWM. I putting off flashing and trying any other ROMs because of this issue. I do love dn3/s5 but id love to try others. Anyone can help it would be appreciate.
Hey guys,
So last night I accidentally wiped internal storage in TWRP. I guess that messed up my partitions or something, I don't know. Anyway, I can still access recovery, and I've tried to do a restore (one that I made back when I was on stock 4.4.2 I think) but after that it tries to boot, gets to "Android is upgrading... Optimizing app Y of X." and once that operation completes it shows the lockscreen for about a tenth of a second, and the phone reboots.
I'm stumped. Anyone know what can I do?
Sorry if this has been asked a hundred times. For some reason the search function in the forums isn't working for me. And I've been looking for a solution all morning.
EDIT: FYI when I tried the restore I did only System and Data and not Boot, because I was afraid that'd cause more problems.
Did you try restoring and performing a factory wipe before booting the newly-restored ROM?
It seems that Marshmallow based roms aren't working, but Lollipop ones will boot. Not sure why as I didn't have any problem with the same MM roms in the past.
More info:
MM roms wont flash in TWRP; after the failed attempt, TWRP says system cannot be mounted until I either wipe or install a 12.1 rom.
Tried to install a stock rom (4.4.2) and it failed in TWRP. Just says "Error Flashing"
Are you performing a full wipe (system, Dalvik, cache, data) before installing or restoring a ROM? Is the phone running the latest version of TWRP?

Yes to full wipe. TWRP is 2.8.7.0, so yeah I think it's the newest? Not 100% sure.
Wiping internal storage should not affect the partitions. I'm not sure that TWRP even has the ability to change partitions.
Yes, 2.8.7.0 is the latester version of TWRP.
If you are on the nj2 bootloader, try flashing this in TWRP: http://forum.xda-developers.com/galaxy-s3-att/general/rooted-ucufnj1-stock-rom-t2985006
Welp, seems to be all good now. Not sure if I really did anything to fix it or not. I tried to install a stock ROM but it wouldn't boot (stuck on Samsung logo) but after that my CM13 ROM installed properly again. The one CM13 ROM I have still wont install at all - maybe that file became corrupt or something? Not sure if that's even possible.
Either way I'm all fixed up. Thanks for all your help.
Cheers
Glad you got it sorted out. If you do figure out what you did to get it working, post your answer as it may help others that are in a similar situation.
I'm having some issues flashing any ROM. TWRP will not wipe data, or internal SD
For some reason, when I go to wipe data and factory reset, TWRP will say it was successful, but nothing ever gets wiped. It will only wipe system if I choose to. I've gotten a ROM to flash but when it boots up, all of the old apps and user data are still there and it makes everything crash. I've gotten into settings to do a reset, it reboots into recovery, runs the script, and still nothing wipes.
What I have tried:
Old TWRP, newest TWRP
CWM (seems to wipe but it won't get past the note 2 screen after flashing anything)
Wiping with CWM, flashing TWRP, then flashing a ROM (still loops after the note 2 screen)
Is there a terminal command I can use in TWRP to manually wipe things?
Thanks for any help I can get, I've flashed so many phones I can't remember but I've never had this issue
Maybe flash back to a stock ROM, factory wipe using stock recovery, then flash TWRP?

Well when it bootloops t the Note 2 screen, I have to flash a ROM with Odin to get it working again. I've flashed a stock ROM with Odin, flashed TWRP with Odin, tried the wipes and it never wipes anything... I'm lost...
Isn't there a format function in TWRP that is seperate from the factory reset or advanced wipes? I was also trying to find a terminal command to type in the terminal in TWRP... I'm a little stumped...
I'm sorry, I read that too fast... That may actually work, wipe it in the stock recovery, and just don't let it boot into the system before flashing other stuff... I'm gonna try that out... Thanks man, I'll post back about it...
Since you are flashing the phone with Odin, is it a stock 4.1.1 ROM you're flashing? Which custom ROM are you flashing to the phone?

The stock ROM I used is I317-ODIN-UCUCNJ1-Stock without the booloader packaged in, I'm still on the old bootloader. It's 4.4.2
The ROMS I've tried to flash was
Cyanide (Error 7, says incompatible data, please wipe the phone)
Resurrection Remix (Error 7, says incompatible data, please wipe the phone)
Latest CM10 Nightly
I got CM10 and Resurrection Remix to flash a couple times, but the phone boots and all the old apps and data, including the AT&T ones are still there, and the system keeps crashing. Then I change the recovery to CWM because it seems to wipe, change back to TWRP, flash the ROM and gapps again, but it bootloops at the Note 2 screen.
Should I try the 4.1.1 ROM and CWM? Whenever I'm going from a stock TW to non-TW I like to format everything, data, cache, system, and internal SD, but of course TWRP won't wipe the data or the internal SD.
It's probably because the bootloader and modem are too old for the roms. Recent roms will need updated bootloaders.
Ok, I had some more time to mess around with this today and figured it out. I feel kind of dumb but oh well, I got it.
TWRP was already loaded on, so I went to messing with it again. The 'Swipe to factory reset' was not wiping the data, and there was the 'Format Data' button right there in front of me. I did the factory reset, format data, rebooted recovery, wiped dalvik, cache, and system, then flashed the ROM and everything booted up just fine.
Thanks for all of the help!
