[Q] Newbie questions (don't kill me Im new!) - Nexus 7 Q&A, Help & Troubleshooting

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.

[Q] Accidentally Wiped /data, Stuck in TWRP..

Well, it looks like I unintentionally wiped the /data partition using TWRP right after I did my first backup after rooting. Now I obviously can't boot since system, data, cache, etc. are wiped. The backup I just made was also wiped. As others mentioned in the TWRP thread, it's a bit different for the Nexus 10 compared with other devices - out of the 11 android devices I've had I've never done this!
Anyhow, can anyone a solution to getting a ROM back on my device? I can't seem to mount anything to my PC using TWRP. I can get fastboot working, but not ADB or file system mounting.
Thanks
Ehm, does the Nexus 10 have a ad card? If yes, use another phone to put a Rom on it and then flash it trough twrp

have you tried mount sd storage? or you can try the toolkit in the sticky thread.

Get a stick drive, sd card reader, etc. Put a rom on it & transfer via twrp file manager

Just boot into fast boot and flash the stock images.

can you use adb to push a rom to flash?
TWRP allows you to adb sideload ROMs. Google TWRP adb sideload and it'll walk through the steps. You can also search the Original Development section and find MSkip's toolkit which I believe can flash ROMs and whatnot from your computer. It will also automate installing the proper drivers if that hasn't already been done.
Thanks for all the help. ADB wasn't working in TWRP - I believe it was a driver issue on my PC though. However, as jellydroid13 mentioned, I was able to use fastboot to flash the stock 4.2 image from google, and then boot up from there. Thanks again!

Add me to the list of people who have wiped data over 9000 times in CWM and after updating to twrp and doing it there, have lost everything. I have backups, but am having no device found with adb sideload and suffice to say im a little confused. Confused why "wipe data" and wipe SD card and wipe SD EXT all do the same thing.

(i'll look for an OTG cable^^)
i had a similar problem several days ago
used ADB sideload to flash ROMs
why adb anything when like jellydroid said you can use fastboot and push all partitions and restore to stock?
I'm facing a similar issue but my device is Moto G5s Plus.
The problem I'm facing is that I accidently wiped out the mobile's system completely, and now it does not even have an "internal storage" partition at all (since it shows 0 MB). Hence, I cannot even transfer any files to my mobile because my computer does show the phone detected but no "internal storage exists".
Please help me out..

[Q] Question about TWRP backups before I wipe.

I have never had a device without a removable SD and am used to having the contents of my SD protected when I wipe and then flush, i mean flash (hah). When I wipe with TWRP, will I lose my pix, audio, etc as they are not on a separate partition?

If you lost your pix, audio, etc that would really really suck. I don't think I would flash new ROMs daily. So of course the contents of internal SD are protected. UNLESS you choose to wipe internal storage in TWRP so don't mess with those advced options. They call it a factory reset in TWRP but its not like the phone option to factory reset which does wipe internal storage.
Your app data is lost. Just back up with titanium backup. After flashing new ROM install only TB, then restore apps and data (no system apps!) and you're done!
And make sure you have a backup! If anything does go wrong just restore it.
alright so lets say i download a rom and put it on my internal, then i boot into twrp do i just factory reset or what? i dont understand what to wipe to keep internal intact sorrry im a noob
in TWRP do a factory reset and install the new rom (and gapps if its CM rom) and you are golden.

[Q] formatting internal SD card

Hey Guys,
After doing some reading about Folder & partition structure of Android, I am totally confused & in worse condition.
My question is simple;
Flashing a new ROM does not reset/delete the folder in the internal SD card. Since I have capacity problem, I would like to delete those folders and make fresh start. How can I do this? Is is safe to delete /android/data folder?
Under setting/storage, the sum of all folders is around 5.2 GB, while it shows the total as 8.8 GB. Where is the rest of my space?
Best Regards
I have a GT-I9500, running Arrow ROM 11.0 (android 4.3)
Philz recovery has an option to format the device internal memory.
Sent from my GT-I9505 using XDA Premium 4 mobile app
9505 has 9.13gb
in recovery before flashing a rom you have to wipe data, system, cache, dalvkit cache, etc
i wist phyl recovery sayd wike internal memory, but there is no option like that, only wipe sdcard1 (external)
Okay this is what you need to do.
First download official firmware through SamMobile, then flash the .tar file through Odin, the boot into recovery, factory reset, the flash the same .tar file again. This will wipe out ALL your data on internal storage and give you a true fresh start. Of course after that if you're not happy you can always flash a custom recovery and flash a ROM.
Thanks for the replies. Going back to original firmware, seems like a tough route.
When I connect my device to windows, it simply allows me to format the SD card. What would happen IF I just do that? Would I brick the phone or loose an irrecoverable important data? (I don't care, If some bloatware does not work or loose its data)

I'm pretty sure if you format the internal card from a Terminal prompt, you will brick your phone.

No. wiping through philz does not erase your efs directory.
However, you can always backup your efs to be totally safe

[I9505] Recover files

Hello Guys. I'm desperate as yesterday i did try full wipe on my brother galaxy s4 via stock recovery and I did wipe whole phone including photos and videos. I'm so surprise as this never happened on my old s2. Now I'm trying to recover some files but s4 blocking access to those files. Phone is rooted running 4.3 Any advice please? How to remove those blocking system ? Please Please

I believe there is option via for ex dr.fone software but unfortunatelly s4 blocking access. Wondering if I flash any non stock rom it will help
if they were stored on the internal and you formatted it, they are basically gone, as i don't think you can mount this in windows, you will only have limited access to certain files via the mtp interface.
if they were on your ext sd card, remove it and use a card reader to connect to your pc and try recovery software?
as have been deleted in stock Recovery I do not believe to be restored
Guys you both right. Still no luck on stock rom. Just wondering if I flash for ex SlimKat will I be able to mount internal storage? Thanks

This is part of how to install SlimKat
Reboot to recovery.
In recovery make a full wipe as per these instructions:
In CWM perform wipe data / factory reset and in mounts and storage section format system.
In TWRP choose advanced in wipe section and wipe dalvik cache, cache, system and data.
Flash SlimKat rom zip.
Flash SlimKat gapps zip.
Reboot, setup and enjoy.
What's up
You will delete,format again,wipe again

No writing access to internal sd card after restoring backup

Dear forum members,
Im having issues with writing to my internal sd card, here the descripption of what i did:
I installed the rom Phronesis v6.2, everything was working perfectly until I realized that xposed was missing, I decided to install it by flashing the xposed-v80-sdk22-arm, unfortunately I got a boot loop so i decided to go back to my original stock rom (4.4.2) restoring a nondroid backup.
The problem is that after restoring it seems that I lost writing privileges to my internal sd card, using es file explorer shows that the storage/emulated/0 folder is empty, but it displays that is using 16 gb from 26. Using the stock “my files” the folders are displayed but I cannot copy anything to it (failed to copy). Applications in general work (some force closes) but I cannot save any settings
If I connect the phone to a pc, i cannot copy any files from the computer to the internal or external sd cards, however I can copy from the external sd to the computer.
I tried to format clear cache etc and restore again but the issue persists.
Can anyone be so kind and try to help me figure out a possible solution?
Thanks in advance

1. Go to your custom recovery and wipe all (system, data, dalvik).
2. Reboot in DOWNLOAD MODE and flash the ORIGINAL STOCK android 4.4.2 firmware via ODIN.
3. Root your device and flash via ODIN the custom recovery again.
4. Restore your nandroid backup.
5. Done. Good luck :highfive:
Hello Joku,
Thanks a lot for the reply, i fixed the issue by formatting the internal sd, wiping all (system, data, dalvik) and then restoring the nandroid backup, now all works.
Thanks again!
