[Q] Newbie questions (don't kill me Im new!)

Hy there I love xda and im a new user to xda nexus forum
With excelent guides I learnt how to root unlock and install custom rom (quite easy let it down into your internal storage and install from zip)
but I have few questions..
When I tried to wipe data and cache I accidentally did factory reset which ended up in no installed rom, internal storage empty and I was in custom recovery and I couldn't connect to computer, so I had to start from 0... last times I've been selecting wipe data and cache.. but I seen that in my nexus 7 some old files are still there (under a folder called 0) What should I do to make a clean install? which option of the new recovery should I choose? thankyou

Use TWRP for recovery and to do a clean install wipe all data from TWRP.

I'd flash a stock recovery image onto your device available here which would restore your device completely back to stock (with your bootloader unlocked) From there I'd just re root and do what you want. However I'd personally use CWM Touch Recovery myself, but I just like that recovery more (have used it and the non-touch version for ages and on many devices)

I actually have Team Win Recovery Project..
under wipe I can find
Cache
Dalvik
Factory Reset (This is the one I use.. but It leaves in my internal storage with a folder called 0 and my old data from previous roms is stored there)
System
External Storage
Int. Storage ?
Format Data (I did this and I lost everything except TWRM which I could boot at it (but I had no option to install from zip neither couldnt transferr a file through usb mount sd card didn't work))
Which one of all of this should I run before doing the install zip from sd card?

I think it would be easier and cleaner if you restored back to stock before trying to re root, flash recovery, etc. If you have no important data on your device I'd go for it. If you do have important data, then try and pull it to your computer and then flash a stock image and re root etc.
I always find that in times when my device is screwing around, or I have file dregs around the place, I find it simply easier to backup important things and flash a stock image.

[solved] E:/error opening '/data/lost+found' after Factory Reset

Hi, today i wanted to do a factory reset and clean install my phone
im using TWRP 2.3.3.3
after factory reset in the wipe menu, at the end i see a line E:/error opening '/data/lost+found'
basically i know what does lost+found folder does in linux, but i forgot whether i have seen such error line before when i do factory resets.
in the file manager of TWRP i then see /media and /lost+found in the /data partition. when pressing into /lost+found, TWRP cannot open it
after this, wiping /system will also give me the same message at the end even it is "Done", as well as cache and dalvik, etc
then i go on flash rom, gapps, kernel, after 1 or 2 boots i go back to recovery and wipe cache, there are no such line anymore
however there is now TWO /lost+found folder in my /data partition
is this a normal behaviour? i didnt pay attention but are there 2 lost+found folders in /data partition for everyone else too?
i have backed up my sdcard and is ready for a /data wipe, any advice is appreciated. thanks in advance!

update: well really hasnt seen it anywhere tried very hard searching on google
maybe just **** happens sometime as i rushed updating the su binary together with restoring android ID in titanium backup altogether without carefully rebooting etc.
factory reset, formating every partition for N times didnt help. returned to completely stock (unlocked bootloader ofcourse), flash twrp 2.3.3.3 clean and no more that line anymore after factory reset. hell gonna start my sdcard restore now...

I was researching google for this same exact error message, when I came across your thread. I doubt you are still having this issue, but I wanted to reply with the solution in case anyone else comes across this post. I was able to solve this error message by installing a new ROM. It doesn't matter which one you install, any will do. Then open your file manager of choice, of course one which can go up to root level. Browse to /data, and then you should notice that you do not have a lost+found folder. However, you should see a lost+found file, all the way at the bottom. I renamed this file to lost+foundOLD, and then created a new folder called lost+found. Next, reboot into recovery and once again wipe both caches, system and factory reset. You should no longer get the lost+found error. Make sure to fix permissions as well to make sure.

just had this issue and was solved by dropping back to twrp 2.4.x.x and doing data format.

No his error and mine are different. We have two lost+found dir and no file. If i delete them and make new lost+found folder. It automatically makes 2.

I am having this same problem. I just did a restore to my last backup, but it in TWRP it says mentions the error over and over again. I looked in /data and I found about 10 files called lost+found, but I do not have any folders. Any suggestions?

Full Format data worked for me

I just encountered this problem after updating a CM nightly and it bricked my phone. Restoring from a nandroid backup would ultimately fail and I was getting all kinds of weird problems (stuck in boot loop, graphics appearing garbled, etc). After looking closer at the logs during restore, I noticed E:/error opening '/data/lost+found' appearing several times, an then it would indicate 'done' and restart but would end up with the same problems.
Even after doing a factory reset, I had no luck in restoring my phone. So I did a factory reset again and installed a CM stable release thinking maybe my ROM / backup was messed up but noticed the same E:/error opening '/data/lost+found' message. However, this time around I managed to get booted far enough where I could connect via USB and backup files from my internal memory to my computer.
At this point I booted into recovery (TWRP 2.5.0.0) and did a full wipe including internal SD using the Format Data option, whereupon I was able to install the CM stable release without issue - no more lost+found error! I then upgraded to the nightly version of my backup and restored with success. Long and stressful night...

All you simply have to do when this happens, is format data ( the one where you type yes ). After this, everything SHOULD be back to normal, for the most part.

Worked perfect for me. Very easy to miss that simple "Format Data" button in TWRP. Simply type 'yes' and problem solved.
I think I got this error when I flashed SlimKAT 4.4 over on my P880 and I had the USB cable plugged in and the partitions mounted (as I had just transferred the install.zip to my phone)

[Q] flashing ROM, lost SD card contents

This has been bugging me and I can't seem to find anything on here to explain it.
I have installed custom ROMs on my N7. Problem is most ROM instructions say to do a full wipe/factory reset. When I do that, the downloaded ROM that was sitting on the SDCard gets wiped out as well.
I then have to go back and search for info on how to reset/restore the N7 and start all over, because the recovery (both CWM and TeamWin) don't let me mount the SD card to copy the needed zip over.
How can I do the recommended data wipe without losing the sd card contents?
Failing that, what's easiest way to get the ROM zip back on the N7 when the recovery won't allow it?
Thanks

dont wipe data...
just do a 'factory reset' in custom recovery...then flash a rom

I use TWRP & don't wipe everything, just System & Factory (to delete installed apps).
This is after wiping Cache & Dalvik Cache.
Unless I'm missing something a data wipe will wipe everything except recovery.
I don't think we have the option to exempt the media folder like on other devices.
(you type faster than me PG)

I appreciate the suggestions, and I've done the factory wipe. It wiped out the /SDcard folder contents where the zips were.
How do I get zips back on the N7? tried ADB, tried sideload from TWRP, nothing works.
Having many more problems than the last time I did this.

factory reset in TWRP doesnt touch /data/media
are you sure you are on the most recent version of recovery?

updated to latest recovery version, that seemed to be my issue. sd card now untouched.

Pirateghost speaks the truth.
The stock recovery however, wipes everything with it's "factory reset".
It's a little bit unfortunate that the identical terminology is used. No doubt new folks will occasionally get bit by assuming they are the same.
I haven't used cwm yet; not sure what it means by "factory reset" - or even if it uses that terminology.

[SOLVED] Cannot mount /sdcard or flash in recovery following phone encryption

Hey guys,
I recently encrypted my phone for my work e-mails (the Exchange server required it). I made a complete Nandroid backup and also entire Titanium backup before encrypting, just in case something went wrong. But the encryption went beautifully.
However, I've noticed that I cannot mount /sdcard or flash anything from recovery. I can't update my Franco kernel or CM nightlies... It's a bit annoying because I want to keep flashing! lol.
My phone asks for my password everytime I reboot (in order to decrypt sdmount and mount the ROM), so I'm assuming this is the reason I can't mount it in CWM recovery.
Anyone know of a bypass or fix for this?
I don't really feel like restoring nandroid backup or doing a factory reset everytime I want to flash a new nightly, it just doesn't make any sense (besides I haven't even tried to see if I can restore from nandroid or factory resetting, they might not even work because it can't mount /sdcard?...)
I've searched around the forums for some complex solutions such as using ADB or Odin but I'm not interested in that.
Thank you!
UPDATED:
Ok guys so basically restoring from nandroid did not work because of the sdcard mount error.
I did a factory reset, erased all data and format system. But I couldn't format sdcard or even user data as it didn't have access... Basically the phone got bricked from then on and I had to completely restore back to stock bootloader/recovery/stock rom with adb/fastboot. Instructions are found here:
http://forums.androidcentral.com/nex...e-restore.html
Hopefully this will come to use to someone else. I've heard that TWRP does not have this sdcard mount problem with encryption as does CWM, so that's what I installed this second time around.

Why don't you just transfer the files regularly without entering recovery mode?
The recovery doesn't allow mounting to the PC. It just doesn't work.

I've never mounted to PC in recovery. My files are backed up on my computer and nandroid as well.
My issue here is that I can't regularly flash new nightlies (and thus mount internal /sdcard to do so) following the phone encryption.
Since my internal /sdcard path is encrypted with a password, CWM recovery can't bypass this and it gives me the error "cannot mount /sdcard".

bump?
Any help would be highly appreciated!
Is this a lacking feature in CWM Recovery? Have the developers looked in it? Or is there already a fix for this without doing an entire factory reset?

Daily bump.
Anyone there? (echo...)

If you want to recover the data from SD card, you do not use the SD card.
You can try to recover the data from the card with some specific software.
I will try to fin one I used before.
It will take few minutes... do not use the card.

Many thanks, this link helped me restoring my Nexus 4. I enabled "encrypted storage" and wanted to root the phone and almost bricked it.

It's also possible to flash the stock recovery with odin, then do a real factory data reset and be able to install a custom rom, after (or before) which you can reinstall a custom recovery.

[Q] TWRP backup fails on data partition "E: Unable to stat /data/data/../cache/ .. "

[Q] TWRP backup fails on data partition "E: Unable to stat /data/data/../cache/ .. "
Whenever I try a full nandroid backup in TWRP it always fails once it gets a few hundred files into the data partition. However, it does complete the backup when the data partition isn't selected.
When I first start the backup a bunch of different red error messages come up for various cache files in the data partition.
"E: Unable to stat '/data/data/[variousapp]/cache/[stuff]/[hashvalue?]' "
I've got a rooted T-Mobile Note 3 with Jedi Elite ROM and TWRP 2.8.1.0, however I'm not completely sure that my phone is legitimately rooted. If I try to open the SuperSU app it says "There is no SuperSU binary installed,...", and applications constantly achieve root access then get denied it moments later. Or sometimes the applications achieve root access with no further issues, it's quite random.
Does anyone have any idea what could be going on?
EDIT: It also should be noted that the files in the error messages can be found when using the TWRP file manager, but when using any file manager application with the OS booted the "/data" folder appears empty.

Anyone have any idea?
Thanks

Well.... from the top of my head I would try to do these things:
1) install one of those "check to see if I am rooted" apps and run it.
2) flash a kernel that has been prerooted, i.e.:that it installs the SU binary to the appropriate location.
3) flash one of those .zip packages in twrp that root your phone.
4) check to see if you can make twrp install root for you ( i think when it doesn't detect root binary it offers to do that).
5) reinstall rom only part as a last resort?
Once you restore proper root access you might need to restore proper SELinux labels to /cache /system /data.
Let me know if you get to this part and need specific instructions.
Best of luck

I flashed the latest SuperSU.zip and that ended up fixing root access. The Root Checker app verifies it as well as other applications being granted root access.
I tried flashing CF-Auto-Root in TWRP and it fails.
How do I restore the SELinux labels for those directories?

You caught me on my way to bed but here are the instructions:
From terminal or adb shell
su
ll -Z
(check for any "unlabeled" text for /data /cache /system)
restorecon -Rv /cache
restorecon -Rv /data
mount -o remount,rw /system
restorecon -Rv /system
mount -o remount,ro /system
ll -Z (you should not find any "unlabeled" /cache /data /system)
Let me know how it goes

I tried all those commands from the terminal and it still shows all of the same "Unable to stat" error messages when backing up
The "ll -Z" command, is that supposed to be double pipe or double L? I'd never seen a double L command before so I couldn't get it to work if that's what it is.

Sorry to budge in but I have the same problem too on my oneplus one. Everytime I do something in twrp it saids unable to stat /data/data/com.android.chrome/something I wiped /data and it still does that. I tried to install custom rom and when it starts it saids something is wrong with my system udi and com.android.phone keeps on crashing. So I don't know how I am suppose to fix this. If I format /data I will lose all my pictures,music,apps,etc. since it will wipe /data/media? Any help?
Edit: Upon reading the first post again, I also can't perform nandroid backup because it fails at /data. Which was why I wanted to try different rom and wipe /data to see if it would be fixed.

alright i said screw it and wiped internal storage and it fixed the issue. i had to push ROM onto the new storage through ADB but it seemed to fix the issue.
For anyone who is wondering you need to do a FULL wipe (ie in recovery wipe EVERYTHING including internal storage), then push or mount devices through recovery and put ROM back onto SD card.

I unzipped the 44s Stock ROM and manually flashed each file via adb to it, that cleared up all my problems. I did lose some data, at least at had my apps, messages, and pictures backed up.

I have this same problem with my OPO and I tried a full wipe including internal storage, but the "unable to stat..." problem still persists. Should I try using the "Format Data" option on TWRP instead of just the "Advanced Wipe"? I tried searching online for the difference but I can't really find any information.

So I had my issue on my OPO also, still never confirmed what the actual issue was but after some googling I saw this thread and maybe one more with the same error description.
From TWRP I went Wipe->Advanced Wipe->Clicked ALL boxes.
From what I could tell the issue is actually on the "internal storage" partition which is your emulated SD Card.
I'm not actually sure what the "Format Data" option does tbh I never had to go that far.
Word of warning, make sure you have ADB working and you know how to push files to your phone. You can in theory use the "mount" option from TWRP and connect to a PC as an extendable drive but this functionality is super flaky and is known to not work on occasion.

you don't have to!!!!!!!!!!!
actually i formated it and i was looking for a way to transfer my zip file to internal storage ........... but when i clicked on backup/restore it started to install and booted normally !!!!!!!!!!!!! (by temp boot file)

Sad I am also facing this problem too. At last I have to format everything to get my phone working again, wiping /data does not work, must wipe /data including media.

Internal Storage failure?
This happens to me all the time all of a sudden. I did not change anything at all, except for flashing a new CM version.
I also get a strange stat error, something with google.photo cache.
Yesterday, I have then flashed the new 2.8.6(7) and that gave my phone the rest. It might be because I flashed through TWRP itself into the recovery partition, but now additional to the backup error above when I want to erase dalvik cache, the recovery just hangs. I also can't restore a backup atm.
Now I have reflashed the real 2.8.6.0 recovery and it still hangs when I want to wipe dalvik... wtf is going on here?
And oh yea, my phone does not boot anymore either, it just loops at the flash screen...
UPDATE:
After I found some info on this thread about similar issues, I factory reset my phone with stock recovery (TWRP was not reliable anymore, even the 2.8.6.0 version that was running perfectly before) and then reflashed the latest CM on a wiped internal storage. Now I am up and running again with minimal loss of data due to my TB backups that are scheduled and save to the SD.
But this leaves a very weird feeling back, basically my phone was rendered useless out of nowhere (I was running the previous CM for 2 weeks already), making TWRP backups impossible and forcing me to wipe the internal storage with all media on it without giving me the chance to back it up (MTP in TWPR was also very flaky and died several times half in copy operations). Something is going very wrong with this phone, never ever had that on any of my 5 previous htc devices and the fact that the OnePlusOne users are among the main ones that reported similar issues, I have a feeling it is linked to cheap storage quality. Motorola is a Chinese company now after all... :-/

Hello,
I had the same issue with my Galaxy s4 GT-I9500, it said "E: Unable to stat /data/...", wiping didn't fix, but after I run "format data", it fixed the issue for me.

I have been going through the same issue. I can fix it for 'a while' (by wiping and formatting data) before it comes back again. Anyone knows how to get rid of this once and for all?
