Nabi2 recovery and space question. - Android Q&A, Help & Troubleshooting

hello everyone.
I'm sure some of this been answer before. I been reading all nabi2 posts here and i still cant find answers to some of my questions. So please don't get frustrated with me. Just trying to learn.
1. Dose anyone know how can I dump original image of my nabi2 recovery.img before I write a new one? Where is recovery image located?
2.Can I delete "factory reset" back up to gain more space on my nabi? Or is there any way of utilizing more space on the nabi?
3.Is there a program/app out there that will let me move data to SD card and free up space. or did this concept died with android 2.1?
4.By backing up my /data /system /and /boot it that all there is. If I wipe complete internal storage is it hard to rebuilt it? is there a way of seeing complete 8gb of storage under windows?
5.Can I install other recovery TWRP? like CWR?
** Just want to say thank you to JMZ and t499user and few others as I did learn a lot from post publish here.**
Thank you

Extract images from Nandroid backup

I know i need to extract them with unyaffs.exe
But i can't find where my camera photos stored ..
Please navigate me to the path ...
Motorola Atrix 2.3.4 device.
Thanks.
Nowhere, they're on the SD card (/DCIM/)
So they are gone ?
I stored them at the internal sd, not in the external sd.
Internal SD... ah, sorry: the Atrix has built-in memory... I wasn't aware of that. That depends on how it is accessed... I still wouldn't expect it to show up in Nandroid backups, but if your lucky it doesn't get formatted and you can still retrieve it. The question is, what device is this internal storage and what filesystem does it use.
Can you still mount the storage on the PC? You should be able to retrieve most of your images even if the drive was formatted using a standard photo recovery tool
I just full wiped everything .. all the storage places too and intsalled new ROM.
OK, i can do that , which revocery tool should i use ?
It's been a while ... I think I used this one:
http://www.z-a-recovery.com/digital-image-recovery.htm
The free version is enough for image recovery.
Thanks
Just recover some of my images ...
But i can't get the full library from the nandroid backup? what information do you need?
I know i can just restore the nandroid backup ... but it will do trouble ... diffrent kernel from my preset rom..
Any ideas?
?
Sorry for the late response, But I just stumbled upon the thread. I had the G2x. The internal memory is just like another SD card. Just that it's not removable. What's backed up in a Nandroid is things like the /data, /cache /boot /system and android.secure partitions. The internal memory is /emmc. It doesnt get formatted in a wipe (unless you say so) and it doesnt get backed up in the Nandroid. Otherwise, your Nandroid backups would be EXTREMELY large.

How can I erase the internal storage of my Tab?

Hi xda,
I'm not a typical android user and this was one of my firsts in messing around with my Tab 10.1. I have GTP7500 which I recently loaded up with CM10 and it's working fine except for the camera. Leave that and what I was going to say is that I'd like to remove my entire Internal Storage ( all the downloads, music, videos ) and stuff, i.e, like formatting the sd card. I'd like to know a way to format the internal storage of my Tab without affecting the system files as I don't want to create any troubles here. So, my questions are:-
1. Whether I can delete all the stuff shown inside the internal storage from my PC directly and would it affect the system? I cannot see any format option when I connect my tab to my PC so, I was hoping if I could manually delete all the files inside the storage and then doing a factory reset from cwm and installing the rom once again?
2. Or is there any app to do this?
3. Or if it is quite simple to do it the hard way, well, entering the fastboot and wiping the whole system (Read it somewhere before) and installing all the stuff again, then please do tell me that too. Otherwise, I'd go with the easy method, i.e, just format the internal storage.
Also, what about the format /sdcard option in the mounts and storages menu in CWM? I'm using CWM 5.5.0.4.
I think doing the "format /sdcard" in CWM should do what you are looking for as I have done that in the past. I would also temporarily back up the /sdcard contents onto your computer as a precaution in case an app was depending on any folders there, but I think it should be fine.
Thanks but still...

Thanks for the quick reply. But would it remove other stuff including the boot files and other core files of Android? I've somewhere seen similar posts and whom did the format /sdcard but they proclaimed they lost whole files and had to do bootloader and install cwm and other stuff all over again to gain access. I've already managed to do format the sd card while installing the ICS official ROM for my tab but I did that via Samsung's recovery menu, i.e, one you get when installing their official ROMs and did a factory reset which erased all my internal storage files. But the same option won't remove internal storage in cwm. So, is format /sdcard the option to do this? I'd be glad to get a clear answer.

Yep, format sdcard in CWM. It will only wipe the data stored there. Your bootloaders and ROM will remain unaffected, however I would still backup the sdcard to your computer before doing this just in case.

I was wondering about this, too. Thanks for helping!

The method above does work. However, if you really want to wipe the whole device completely clean, using Odin to flash stock firmware will blow it all out and make you factory-fresh in one operation.

[Q] Talk, Trebuchet errors. Explain cm10 boot menu? iamafan's build

Hi all, I built my sdcard per: http://iamafanof.wordpress.com/2012/...r-nook-tablet/ (built by"Succulent")
My kids have two NT's. With two 16GB Sdcards, one class4 the other class 10. I know class4 is recommended, but one poster in forums said he's taken images of CM built on class4's and applied this image to class 10's in several cases and has had no problems. So I thought what the heck, can't hurt to try, so that's what I did (using Winimage). It booted fine 5 or 6 times for me, and I installed several APK's of games from Humble Bundle . I turned over the Nook to my little girl and she brought it back to me later showing she gets errors on boot, after swiping the lock symbol to unlock it. One is "Unfortunately, Talk has stopped". If you click OK on this, you get ""Unfortunately, Trebuchet has stopped". Clicking OK on this does nothing, it keeps popping up indefinitely. I don't know if the sdcard is hot pluggable (can be removed with power to the tablet), but she did admit to doing this. So I'm wondering if some corruption occurred to the CM build on the sdcard. Has anyone seen these errors? I could reflash it from the image I made off the class 4, but want to understand what happened so we don't run into it again. The funny thing is, I don't recall the startup wizard off the 1st class4 card prompting me with several screens regarding Google crap like it did on the 2nd card which was flashed from the same image. That was even after telling it I had no Google acct hoping it would leave me alone.
can anyone explain the boot menu you get when you press the N button? (I'm not including the faded selections) I'm wondering especially about the recovery options. Here's my menu:
INT BOOT ( I assume will boot to B&N native OS?)
INT RECOVERY ?
SDC RECOVERY ?
SDC BOOT (Iassume, boot to CM10 off sdcard?)
SDC ALTBOOT ?
START FASTBOOT ?

Yes,
internal boot - boots Rom in emmc
Internal recovery - recovery in emmc
Sdcard boot - boots your sdcard Rom.
Sdcard recovery - boots sd card recovery ( keep recovery.img in root of sdcard for it to load recovery)
Sdcard altboot - alternate recovery ( not necessary, unless you want both cwm and twrp at same time)
Fastboot - fastboot mode , fastboot commands to flash .img file etc with this method .
As for your problem, try entering recovery, wipe cache and dalvik cache partition (I've done this on emmc version, never tried sdcard version of any Rom) this may solve the issue. If not try factory reset.
And removing sdcard while device is switched on is called hot swapping , hot plug is a CPU governor. Not sure if sdcard roms are hot swappable, but I think not.

Thanks.
emmc=internal nook memory I assume?
Oh, and...just to clarify, I haven't modified (rooted) my tablet. (you mention factory reset). I should mention that with the sdcard out, it boots B&N OS just fine.
And the part you say about wiping the two caches, so I should go into SD Card Recovery to do that? Once you get into it, you have various choices like the ones you mention? (I'd read that this choice was to backup your NT to sdcard). And please, I want to be very, very careful not to wipe out the B&N stock OS, so please, any detailed instructions you can give so I don't make that mistake, I'd greatly appreciate it. (I see so many posts on these forums about people bricking their Nook tablets it worries me.)

Um I don't know much about how it works for sdcard Rom. I've always only used emmc version. I guess if you were to enter recovery, it would access the stock cache partition by default , and we aren't trying to clear that.
Try this - use titanium backup (only talking about your sdcard Rom here, nothing to do with your stock) and in options, you may be able to wipe your cache or dalvik cache.
Or,
boot into your sdcard Rom, in settings > backup and restore > factory reset. This will delete all user data and return Rom to original Cm10 that you flashed on sdcard.
Or if it's only google talk and trebuchet launcher issue, install a new launcher (go launcher, adw etc) , then use titanium backup to uninstall trebuchet and talk.

From what I see, titanium backup is an android app. If I can't boot to Android (Trebuchet error loops as I said) I don't know how I can install this to do anything? Nor can I install another launcher or go into Settings as the error doesn't let you get any further.
I guess if there was a way to browse files/folders on the sdcard partitions on the sd to manually delete the cache files.....but if they're linux partitions (ext3 or4) you can't do that under windows...

In cwm, enter mounts and backup, then (if) you see /sdcard /cache, mount that and format that ONLY.
Do not format anything else as some options can brick device (Rom, bootdata, factory etc)
Wiping cache is safe (99%)
Again, I have never used sdcard Rom so I don't know what will show up in your recovery. But if you see something like sdcard cache, it can be cleared. If it doesn't specify sdcard, let us assume it refers to stock emmc.

Select SDC Recovery on the Cyanoboot boot menu -- see steps 7 & 8 of the post at http://forum.xda-developers.com/showthread.php?t=2061536.
If you want to backup the BN stock ROM just in case, see step 9.

I chose sd recovery, chose Backup & Restore, then Backup. It started running right away. It said:
SD Card space free: 228MB
Backing up boot image
Backup of boot image completed
Backing up recovery image
Backup of recovery image completed
Backing up system
Error while making a backup image of /system!
I plug sdcard into PC card reader and the FAT partition has 0 bytes free. So, appears it ran out of space. I saw your comment about 600MB space being needed. So I'm redoing the partitions now.

Why backing up now when it's not working? Fix your issue, then make a backup. So the next time there's a problem you can restore to working condition.

Well, backing up, I think, was a good suggestion by Digimax. So I'm glad I did it. and now i know how to do it for future. Just in case anything EVER goes wrong, I'll always have that image now on my pc. Bad thing was, apparently B&N nook OS apparently keeps lots of APKs around after installing them. I had to make my 1st fat32 partition over 2GB for the entire backup to process without running out of space. backup size=1.6gb
I ran into lost chains - convert to cluster msgs trying to delete the folder of the first failed backup, but it never would delete even after a chkdsk, so I formatted the card and put the original image back onto it, adjusted the partitions, and then ran into a new probem.....the Cyanomod spinning logo never stopping spinning so it won't boot up. So I give up. I don't know if it's that it's a class 10 card that all these problems are happening. barring any other suggestions, I guess I'll make sure the other NT we have runs stable for a few weeks and if so I'll order another class 4 like that one has.

I don't know about your bootloop issue, but I don't think it's a sdcard class issue.
Anyhow, now that you have stock backup, aren't you going to consider flashing cm10 internally? Do you actually use stock?
Sent from my ST27i
I'm a little leery of it, at least while it's under warranty. I don't know how reliable recovery is.? Besides, my daughter wasn't thrilled with it being down for several days with me fussing with it and asked if she could have her "B&N boot" back I admit It is a bit of a pain having to pull it out of it's case, lift the flap, pop-in or out the sdcard to switch between them. (& also to have to remember to always turn it off b4 removing/inserting)
I may do it in the future though. Thanks for the help
FWIW, you don't have to actually remove the card to boot into stock. Just reboot, hold "n" to get into Cyaonoboot menu and choos "int boot" or something like that, and it will boot to stock with the sd-card still inserted.
Great, thanks for that tip!
Card died
I think many of these symptoms could have been caused by a dying card. It did have a corruption error once, and then it finally completely died. Just for anyone else that runs into these.

FWIW, /cache does not need to be backed up, which should help reduce the backup space requirement.

[Q] Understanding Partitions ROM and Recovery on Android

Hi, I have a lot of questions about Android Filesystem, ROM and recovery, i read a lot on internet but i couldnĀ“t understand everything, I appreciate if someone take a little time to teach me the following questions:
These are the partitions I read there are on Android:
/boot
/system
/data
/recovery
/cache
so my first question:
1) why i cannot see on ES File Explorer or Link2SD, recovery partition? where is it?
When i wanted to enter into recovery automatically my phone was restored to the manufacturer status, and no menu was showed, so I have two more questions:
2) Does recovery restore Data and System partition or only clear Data partition and system is not changed?
3) If I open 'ROM Manager' and click on 'Flash ClockworkMod Recovery', will I have the famous menu to save a copy of my actual ROM?
In case i want to learn more about customs ROM,
4) Why everybody talk about to install it on SD? To flash a new ROM do not format the internal memory, I mean the actual partitions system, data, etc...?
5) Is there any way to change the size of these partitions?
from already thank you very much!!

[Q] Understanding the android system partitions

Hello all. Somewhat of a n00b to android. I recently got the new nexus 7 (2013) and have been playing around with flashing roms and using a custom recovery. So i know how to do all of that now but my main questions are:
1. When flashing a ROM(ie CM) what partitions are affected? What is actually being flashed on the device? System partition? Kernel too? Because i notice when i factory reset and then flash a new rom, the same data is still on the internal storage.
2. I know that there's a system, dalvik, cache, recovery and boot partition. Well im trying to figure out what exactly does flashing a rom do? Is internal storage a separate partition from those main partitions?
I apologize if this topic has already been covered somewhere else. I have searched the threads and cannot find a straightforward answer. Thanks for your help guys!
Your device has a fake sdcard this your internal storage which flashing a ROM through your custom recovery does not touch
For the most part when flashing a ROM it will only write to the system and boot partition (occasionally data) but you should be wiping cache, userdata and dalvik and this may be in the updater-script if the ROM you are flashing.
Of course depending on the device there are lots of other partitions namely, bootloader (sometimes split between primary and secondary and sometimes even a third SPL) and recovery, some have a separate splash1, radio/modem partitions, and then you can keep going with a slue of others that aren't affected by a normal flash, a quick search will certainly find you a list of all partitions to your device

1. When you flash a rew rom, the files are maily written to system partition. User apps (or if you download from play store) are stored to data partition. Yes, kernel is being flashed, too! Try to open a rom.zip before flashing and you will see, which files are in which partitions.
2.On my old HTC Desire internal storage was a seperate partition. But on my HTC One i dont really know...wanted to know this, too Sometimes i think its not..
Correct me if i am wrong
Hope i could help you somehow! :laugh:
