Tnx for the mail, but I tried that and some stuff stays even if flashed via ODIN.
I think because System partiotion cannot be erased via Samsung recovery or Factory data reset....
I dont want to install custom recovery, because danger of tripping KNOX...

Does wiping data/ factory reset wipe the cwm based recoveries??

Well i have some contacts in there and i dont want to lose them . so thinking of wiping my phone because its kinda bricked right now but i could still acess the cwm.
yes and no. the backups are on the SD card. the SD card is wiped when you factory rest from the settings privacy menu. a reset from cwm wont wipe the SD card.
The only time factory resets the phone where you need to re root with everything else would be through settings -> privacy -> factory reset.
On the other hand, factory reset via cwm resets the rom you just flashed.
Hopefully I cleared some confusion. Thanks.

There's a version of an unbrick that will keep cwm+ root

[Q] Lost sdcard after restart during cache wipping

I restart my phone because it did a lot of time to reset cache. I regered the time I did it but was late.
Now my phone opens but does not have mobile network and cannot access my /sdcard/
From recovery I can see my sdcard. What can I Do?
Are you fully stock? If so, then format /cache partition and then perform a factory reset via stock recovery.
If you aren't fully stock, and use a custom recovery then I would suggest you to perform a factory reset from the custom recovery (it won't wipe internal sd)..
If it still doesn't work then you need to go back to fully stock by flashing the factory images from Google.

Yep, just keep wiping / formatting cache until it fixes or fastboot flash the stock cache.img

I am not stock at all. I thought if I could copy sdcard to otg before all these.

Just flash the stock recovery via fastboot and then format cache multiple times until it successfully formats! Your data won't be lost.
Since you rebooted before the cache was formatted, it has ended in a messed up /cache partition.
If you want to backup data, you can use adb pull from recovery...
See above
Edit.. By that I meant my previous post

Now. I am pulling my data and then I'll flash stock.
I have a backup before the mistake. If I restore it?

You can try to restore the backup but I doubt if it will solve the issue. However, there's no harm in trying..
The cache partition is messed up.. It needs to be formatted first. That's why I suggested you to go back to stock recovery and format cache...
I have tried wiping cache on Philz Touch and twrp and it didn't solve my problem. I had to format the cache partition using the stock recovery and voila! Everything was fixed.

Yes but if you're flashing stock recovery fastboot you may aswell flash cache.img instead which is a well documented fix in this forum

My bad. I understand to have done this from TWRP. I haven't tried yet to do something from fastboot due to the backup.

Flashing the stock cache.img won't wipe your saved data or backups.. There's no harm in trying.. However, if you're skeptical, adb pull all your important stuff and then do the flashes!
Finally I flashed cache.img and seems that everything is good again. Thank you for your help.

LG Optimus G wont flash

Hey Guys,
Tried installing a custom rom on my LG Optimus G but stucked on LG logo on boot after installation. Now I try flashing the original kdz but when I lunch de flahing process from download mode, my phone turns on into recovery mode on its on. Can somebody help me? Is there another tool to flash kdz??
When you tried flashing the custom rom or kdz did you do a factory reset first and wipe everything except internal sd phone or tablet storage first before you flashed the files ? is the kdz a firmware zip folder ?

No, did that but my problem is solved, My problem is solved. I was able to flash using LG Flash Tool 2014.
Which procedure should I follow exactly not to stuck again. If I factory reset the Rom zip will be whiped. My phone takes no external SD.
Check Ur downloaded ROM MCDev again. That its OK and didn't corrupt..
On which Stock firmware u were before installing MCdev? You should be on 30C
Do you have a custom recovery ?
when flashing roms you need to wipe cache, data, and system before you flash recovery. It doesn't delete internal phone storage, files unless you choose to select it. This is how I do it in a custom recovery .twrp works good for the lg g2
The ROM is OK. I'm on 20G

I don't think you need to factory reset again after you flashed the rom if you did the things before it. Clear the cache and dalvik cache before starting up your device.
is data being wiped during factory reset ? You should
Select wipe data/factory reset and confirm
Select wipe cache partition and confirm
Select advanced - wipe dalvik cache and confirm
Select install zip from SD card
Select from internal SD card or wherever you placed it.
Select the ROM file and confirm.
then start the device. If you have the right android version and everything else you can wipe cache and dalvik cache then try Fix Permissions after flashing rom before you try to start up again.
Does the rom need you to be on a different android version or flash a kernel for it ?

But U have to Format Data and System Partition Also before flashing this ROM.
And U aren't on Stock Kitkat. May be that's the reason. Did U select ur baseband F180K during installation? And did u installed Custom Loki CWM recovery as mentioned in thread?
Everything is alright now. The phone doesnnt stuck on LG logo nomore. The problem was I was not on stock KitKat. I had to upgradde to stock 4.4.2 (30C) before flashing. Thanks to y'all

factory reset my phone

For some reason, I have to factory reset my phone
http://forum.xda-developers.com/google-nexus-5/help/disappear-hard-disk-t3222734#post63254887
Just wanna know, since I have titanium backup on my nexus 5 devices. Does a factory reset (or any kind of wipes) wipe the internal storage of my phone (including the backup).
If so, how should i proceed with my backup if i wanna factory reset the phone
Thanks.

Wait what, why do u need to do a factory reset, and yes, as the name suggests, it leaves the device in the same state that u received it in, blank, but why would u need to wipe the device, I'm going to check out the link, bcuz now I'm interested
I have never seen this happen before and I've owned nothing but Nexus devices, well, to answer your question I have to ask a few, are u rooted, do u have a recovery installed? If the answer to those two questions is no, then connect to a computer, copy the files in your internal storage and place them in a safe folder on your computer, proceed to wipe the device as stated, then copy the files back onto the device, should take care of your internal storage.

That might work, in theory it should, as long as u go back to 5.1.1, or u could just make a data only backup in twrp, download the factory image, whether it be 6.0 or 5.1.1, use the pc and adb to manually flash the images, do this
1) make data only backup, move that backup to pc
2) extract the images, both the tgz file and the zip file inside to a safe location, u only need the radio, boot, system, and userdata images if 6.0, just system and userdata if 5.1.1
3) use adb to flash these images like this:
fastboot flash radio "radio.img"
fastboot reboot bootloader
fastboot flash boot "boot.img"
fastboot reboot bootloader
fastboot flash system "system.img"
fastboot reboot bootloader
fastboot format userdata
fastboot reboot bootloader
Then boot to recovery, flash your backup and that's should be it

No u can't use the factory reset button in settings as the stock room won't recognize twrp, u can however use twer and wipe cache, data, and dalvik cache, or just do the reg factory reset wipe under wipe which should work as well as a factory reset, why are u trying to factory reset tho, if I might ask

because my nexus 5 showing 14gb instead of 32gb. I heard a factory reset will help the problem. I just dont know which factory reset (recovery or in setting) to do.
but if i use twrp wiping cache, data and dalvik (leaving system and internal storage alone).... will it wipe my lollipop os too? will it wipe my storage too?
what is the different between the factory reset under setting and the factory reset under twrp?
sorry for so many questions....

Ok so to answer your question, u can wipe anything EXCEPT Internal Storage, system, and boot and you won't lose anything, personally I would do this, boy twrp and use the regular factory reset, this will error everything except got the OS and internal storage, if that didn't work then I would manually format the partitions

Can't reset to factory or flashing stock rom Huawei G610-u00

Hi, I have a very strange problem. My friend's gave his Huawei G610 to me and asked me to reset it to factory and wipe all the data. I simply went to recovery mode and selected Wipe data/factory reset and then wipe cache partition and finally rebooted it!
Instead of showing the first use screen (OOBE) I noticed that nothing had changed. Everything is as same as before factory reset. I tried reset factory from the setting menu and no change. I also uninstall a few apps and after a restart the apps got back :| I flashed stock rom using sp flash tool and no success. Please help me!
