Hi guys,
After flashing LP update 5.1 I`m in trouble with my 32GB Nexus 5
I got the error msg " E: can`t mount / cache " ( the same for system e.t.c). (before I did this I was on Custom ROM with Exposed framework installed.)
So I tryed to re-flash LP factory img (LMY47D) using fastboot command (via ADB SDK platform-tools) manually one by one according guides I found on xda.
I did it many times but the result was still the same - appears just green "android man" with rotating cube (10-15 min) and than it reboots itself and starts over again.
So I tryed to flash older factory image the same way (KTU48P) and I succeed to boot my phone but instead of 32 GB (normally available ~26GB) of my storage space there is only 12GB available now.
I thing there iscorupted partition but don`t know what to do next :crying: - how to restore it or format it ???
When I try to do that via Recovery I cant mount those partitions so I can`t format them...
When I did it via SDK - fastboot erase user data it takes veeery long time with no result
Could you pls help me how to format whole storage space ( all partitions ) and return back to stock rom with full 32GB space available ???
Thanks
Have you tried this guide http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
There is a "32 GB phone now shows 16GB?" section.

Yes, that was one of the first think I tried.
--> I can`t clear cache & factory reset via stock recovery. Error msg -- "E: Unable to mount `/cache` "
--> Unfortunatelly fastboot erase userdata stucked ( it takes aleady 2 hours it started to erase the data and format the partition ) - do you thing it can freeze or it just can`t mount the data so it`s in loop ?
Any othe idea please , please ?
Have u tried to unmount cache partition from recovery?

I can`t unmount it because it`s not mounted ...
When I tried to Wipe cache partition these errors appears :
PHP:

E: Can`t open /cache/recovery/log
E: Can`t mount /cache/recovery/last_log
E: Can`t open /cache/recovery/last_log

E: Failed closing /dev/block/platform/msm_sdcc.1/by-name/misc
(I/O error)
Did you try
fastboot erase cache
fastboot flash cache cache.img
fastboot erase system
fastboot flash system system.img

Yes
fastboot erase/flash system was OK, but fastboot erase/flash cache got stucked
So after 2.5 hrs witnout any results I unplug the cord and start over again -- the same results
Maybe this will help

Did you Wipe data/factory data reset after successful flash?
That will probably fix your 32=16 problem.
I tryed this tutorial :
http://forum.xda-developers.com/showthread.php?t=1284196
Thanks God it`s not "fried".
So I tryed this
Code:
mke2fs /dev/block/mmcblk0p27
(than reboot recovery)
... but still the same result
Than I tried to start over again from stock img flashing so :
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot flash bootloader
fastboot reboot-bootloader
fastboot flash radio
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot erase userdata
fastboot flash userdata userdata.img
... it got stucked on erasing user data so I had to unplug the cord, restart bootloader
When I re-start the device appears "swireling" dodts (the boot animation) but no step forward, still booting....
When I tried to boot in recovery - dead android with red "!" appeared
Any other ideas what to do esle ?
Should I flash CWM or TWRP rec. instead ??
How this can be fixed ??
PLEASE !!!!:crying::crying::crying:

If you are getting an android sign with a red triangle it is normal for stock recovery.
You must tap volume up/down and the power button all together to get to the recovery menu.
Don't hold them in. Just tap all together at the same time and let go. It takes a couple tries but it works.
You'll then get a menu that will let you wipe data/factory reset.
use volume up/down to scroll to "wipe data/factory reset" then power button to select.
looks something like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

try it and reply back the result.

I have no clue how to fix this can you help me pls ??
I would go to fatsboot and try to erase partitions and re flash again. see what happens.
If your data partition fails again we can try adb shell to repair your data partition.
I tried but again got stucked on erasing userdata...
I start research again and search for solution around partitions and I found this ( exactly my problem)
http://androidforums.com/threads/unable-to-mount-cache-while-doing-factory-reset.901188/
and solution for this was posted here on xda
http://forum.xda-developers.com/google-nexus-5/help/lost-cache-partition-fixed-t2949752#post58720690
this link helps me to get back to 32GB storage space (in fact ~ 26GB but doesn`t matter)
[The problem was exactlly the same missing EXT2 partition on cache partition (27)]
But error msg Can`t mount `/cache` still appears So I was not able to flash stock img LP 5.1 but I manage to flash 4.4.4 KTU84Q
It boots us and works like charm, but... ... still can`t mount/erase cache so it`s not fully solved yet but at least I can switch on/off the system now.
Can U pls help me with this mounting / partition problem ???
can it be fixed by stock OTA from KTU84Q to 5.0.1 and than the same to 5.1 ?
I had like 2 years ago similar problem with htc sensation but i fixed it by formating ir with ext2 and the reformated catch with ext4. Try to find something inside sensation forume

Ok. So you are now successfully running 4.4.4 KTU84Q.
What happens now if you try flashing the stock cache.img of 4.4.4 KTU84Q:
fastboot erase cache
fastboot flash cache cache.img
Also, you could try and see what happens if you flash LP 5.01 lrx22c instead of 5.1 and do factory reset immediately after flash.
Even I manage to boot under KTU84Q the partition is still "lost" - means internal storage is ~26GB thats OK; but the error msg E: Can`t mount /cache bla bla bla still stays.
Actually I have these partitions :

My guess is it needs to be formatted to ext4 not ext2.
KTU84Q probably can not recognize ext2.

Again it looks like cache should be formatted ext4
Compare line 22 and line 27.
My line22 fsc is not formatted. Yours is formatted ext2
My line 27 cache is formatted ext4. Yours is not.
That is the problem.

Finally I got to the stage where the ext2 partition stays ( do not disappear) after next flash.
How I did it - format the partition to ext2 than manually flash KTU84Q
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot flash bootloader "name of bootloader"
fastboot reboot-bootloader
fastboot flash radio "name of radio"
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
Than let the system update itself to 5.0.1 LRX22C
Now the erroe msg is gone (E: Can`t mount /cache) but agree those messed up partitions must be fixed.
The question is how ?
- should I install TWRP rec. and let it fix it when the cache partition is mountable now ?
- or should it fix it via ADB SHELL ? (and how ? mkfs.ext4 /dev/block/mmcblk0p27 ? )
- and how to erase line 22 in order to have in unformated ?
--- > or should I try to flash custom ROM over this ? - I don`t think so
Could you pls help with this ?
!!!THANKS!!!

If it was me, the first thing I would do is flash TWRP. Second, make a full backup using TWRP backup function, then save/transfer a copy of that backup to my PC.
That way, moving forward id' have an easy way to restore the device back to it's presently functioning Lollypop state.
After that I might try the ADB shell command from TWRP you mentioned mkfs.ext4 /dev/block/mmcblk0p27 and see if that manages to re formats cache to ext4.
I've never tried this, and don't have much experience with parted, so I cant say if it will work. So proceed at your own risk.
As far as fsc( I think it means file save clean)partition goes. I honestly don't know but Ill try to find out.
Meanwhile, hopefully someone else with some mad partition skillz will chime in.:laugh:
TWRP coruupted all I did before - it tryed to repair broken partitions with f2fs but they are gone now
So I am 2 steps back

If i try to install any fw with cwm, it doesnt change. Smartflash, same thing.
So next to try is fastboot method for getting to original ics(and get imei back).
If that doesnt work, next is adb push and flashing.
As some guested my phone is having Groundhog day, everytime it starts from clean table.
All settings all gone, apps etc.
If that thing was something else than 3D, i would throw it out of window.
And same thing with recovery, 5.8 stays there.
Parted doesnt remove partitions, format is missing.

Is 5€ enough?
I have heard of this problem before. When you install any app, turn off your phone, take out a battery for 10min and get it back in, turn it back on, do you still have that app installed or not?
If you don't have that app installed after the restart... I think it's a hardware problem, the flash chip went bad. :/
Is there any way fix if flash chip is dead?

Samsung Galaxy J5 Pc Suite and Usb Driver Installation
You should know that if Samsung Galaxy J5 smartphone is powered by a corresponding MTK processor, here is explained how to install the Usb drivers and Pc Suite for the model of this type.
1- Run and use as an administrator if you are Samsung Galaxy J5 Usb drivers and Pc Suite work very precisely and correctly.
2- Enable USB debugging on Samsung Galaxy J5 to do that, please go to Settings> Developer Options.
3- Download the driver to the computer's usb driver Extract files using WinZip or WinRAR, find the file "PdaNetA4150.exe" and start note (Be sure to close all programs).
4-Select the Type phone model (Samsung Galaxy J5 Smartphone), Please select press / click the install button.
Now you just connect Samsung Galaxy J5, there will be a popup message saying your phone is connected. Congratulations you have completed the installation.
thanks the PdaNetA4150.exe file did the trick and now adb get's recognized via twrp
and this is the only place i have acces,,, i cannot boot, no bootloader recognized, nothing...
after everything i try i get unable to mount /data
any command to erase, mount everything?
If you have TWRP, I think ADB works in TWRP whereas if you boot your phone into download/bootloader mode you use fastboot. So what you need to do is find the correct drivers for FASTBOOT NOT ADB as they both do different things, require different drivers and are used in different modes. You might need to manually update them using Device Manager and downloading the drivers.

please some moderator if could move this thread to galaxy j support forum!! thanks !!
Hello to all
I am fighting since 2 weeks with a GT-P5100 that seems to be in read only and in boot loop (it shows the CM9 boot animation and then reboot ...). This after a simple update of some apps that seems to have corrupted the sdcard inside ...
I have tried to clear the cache and the user data via the recovery mode, but nothing happen ... (boot in recovery, choose to wipe data/factory reset and wipe cache partition)
To make a long story short:
I am able to boot in recovery and enter as root via adb. Whatever change I do in the filesystem it seems to be done, but when I unmount/mount the fs or reboot I find the same initial situation !
So for example:
a) enter as root, mount /data, delete data content via rm -rf /data/* ... then if I do ls -la /data I see the device empty ... if I unount /data and then mount /data .. all the files are there !!!! :-O
b) enter as root and activate parted ... remove the data partition (for me n. 10) and quit. Run parted again and the partition is still there :-O
c) enter as root and touch a file in any filesystem ... when I ls after I can see the file ... as soon as I reboot, not such file is there
I have tried with ODIN and HEIMDAL (booting in download mode or fastboot mode) also to flash new system.img from stock roms and different recovery.img (currently I have CWM-based recovery v6.0.1.0)... no way. system.img flash does not work, while recovery.img flash say ok, but when I reboot in recovery mode still find always the same partition :-O
It seems somehow that the overall internal disk is in read only and - I do not understand why - when I do changes they are recorded locally, but when I reboot the fs really does not store anything.
BTW, this is my partition table

I think I did some mistakes while trying to reflash a rom on my Sony Xperia S (lt26i).
I was following this guide, the first time it worked but then I decided to ungoogle my phone but it went bad.

My problem is that I deleted my OS and TWRP can't read the data partition nor mount to Windows.
So now, with djibe89's help (the OP of the guide), I managed to figure out that my data partition is corrupted.
Using the adb shell, like on step 12 of the guide, I went to the partitions and it gave me this

The partition 14 should be the data one, that i already merged with the 15 the first time i flashed the rom.
What should I do?
try deleting it and let Android generate new one??
Code:
fastboot erase userdata
fastboot format:ext4 userdata
fastboot reboot
now there's a high chance that your device doesn't support " fastboot format:ext4 userdata "
here's an alternative
fastboot erase userdata <~ never reboot your device after typing this command you would go on infinite bootloop type the next command ...
fastboot reboot recovery <~ if this command does not work and just restarted your device instead of going recovery mode you are now on bootloop ... access recovery mode by pressing combination key instead
via recovery mode do "wipe data / factory reset"
then reboot

the first method didn't work because of the format command like you predicted.
then i did the <erase userdata> but i think the <reboot recovery> command isn't available because it returns me the commands list. so i used this command from the list
fastboot reboot-bootloader

then unplugged the usb and rebooted on twrp.
now my data partition went back to 0mb (going to wipe -> advanced wipe -> data -> repair or change file system) and i can't even reformat it.
should i re-do the adb procedure to recreate the data partition?

yes your device won't boot without userdata partition since it got deleted with "fastboot erase userdata" so you need to recreate it by "formatting" it somehow
so i wanted to "recreate" the data partition with adb but now i can't even use adb.
i went to mount on twrp with the phone connected and the cmd still running from 2 hours ago. when I type adb devices I can't find
... is it possible that i did some irreversible mistake?

you have TWRP flashed? you can't use it to format data?
also looking at the Sony Xperia S (lt26i) specification it was released back in February 2012 i guess it has serve its purpose for too long it is time for it to retire
I have been try to build TWRP for SM-J737S today, finally i got it.
but when I flash it, It say to me "could not do normal boot invalid ramdisk length".
I wanted to fix it, but I couldn't get any information from google
No one may have mentioned it because it is too simple a matter for some people, but I need help with it.
please help me
Post your recovery.
We're not Carnac the Magnificent.
here's my recovery file
Your ramdisk looks ok, it spans from 11c5800 to 2005182.
You have a DTB from 2005800 to 20a0cac
In Android header type 0 (which you have) a DTB should be snuck in after the kernel.
Surely you meant Android header type 2?
Do you have your stock recovery?
I can't sure what is Android header type.
I think I need more study to find what i did wrong...
thanks for your help.
here's stock recovery
Your stock recovery is type 0 and has the dtb after the ramdisk too.
I guess that must be ok for your device, but it seems non-standard.
I'll take another look.
I'm still scratching my head.
In ye olde times pagesize (quantization on Android images) was 4096.
Then they became appalled at the waste of potentially 2048 bytes on a 30 Meg image.
So some folks changed the pagesize to 4096. (Savings!)
Then people decided to park non-header-referenced things after the image.
Oh, boy.
Like AVB0 signatures. These were quantized to 4096 even if the page size was 2048.
So now your (stock) image puts the DTB after the referenced parts of the image.
It's quantized to 2048 (the page size).
It also has this "DTBH" header that I've never seen before.
But we do find 5 (five) dtbs (just in case you want to load this on another model).
And after that in the stock image, we find (at a 2048 quantization) a "SEANDROIDENFORCESignerVer02".
Who the heck knows what that is.
Then there is the obvious issue: Youre recovery is over 32 MB.
Is the partition that big?
surely I need to chack partition size.
I'm trying to get root..

as you can see, RECOVERY partition is bigger then 38mb.
I have no idea what the problem is
Ok, looking around it seems like that error is just what it says.
There seems to be some hard limit on the size of ramdisks for recovery.
Code:
ramdisk 14,940,546
ungzipped ramdisk 34,343,936
I'm not sure if they mean the gzipped ramdisk or the ungzipped ramdisk (raw cpio).
You've got the kitchen sink in there.
How about getting rid of 99% of that terminfo junk?
You really want the Python stuff?
I tried to make ramdisk smaller today, but I failed.
I couldn't figure out which files were important and which ones weren't.
Actually, I'm used to using linux, but I know very little about Android system
Can you tell me what I should do or search?
@voskresenie
Well, here's a shot for you. I removed all the terminfo and Python stuff.
I had to manually extract the DTB and stick it on the end.
Give it a shot. It weighs in at less than 32MB
now it doesn't say "could not do normal boot invalid ramdisk length", but I can see black screen and irregularly flashing backlight.
is it possible that I solve the ramdisk size problem in the source code?
I think I need to change setting and rebuild TWRP..
Hmm, did you check to see if you had ADB?

adb doesn't work.
actually, windows says USB device recognition failure
It could be that I screwed up or that there was an actual problem in your TWRP build.
Are you testing this by fastboot boot recovery.img?
Or are you doing fastboot flash recovery recovery.img?
If you are doing the first one have you tried with the stock recovery image to make sure that works?
most of samsung devices don't have fastboot.
instead of fastboot, they have download mode.
I think the work that i do is play same role fastboot flash recovery recovery.img
It probably looks like separating partitions by file name.
If I use a name other than recovery.img or boot.img, the flash fails.
Did I mention that I hate Samsung and wouldn't take one if you gave it to me?
I did mention that the stock has some custom signature at the end.
Try booting the stock recovery file that you posted like you are trying to boot your TWRP. Does it work?
If it works you can try truncating it yourself to 27,123,712 bytes, 0x019DE000
See if that runs.
If you can't truncate it, I could post it.
