[Samsung Galaxy Nexus] shaantcs:
I've looked at all the previous threads about reboot loop, but this only happened to me recently.

Model: GSM Galaxy Nexus I9250 Takju Maguro

ROM: CyanogenMod 11 Kitkat

Recovery: Clock Mod

OS: Android 4.4

Basically, my phone has been working fine for the last 2 years. I had only one issue of phone getting sloe down. That I fixed by rooting and installing Lagfix. I've been using this ROM for the last one year and it was fine. Suddenly though, I got the error, "Unfortunately, the process com.google.process.gapps has stopped". Then the phone went into boot loop

I've tried rebooting into recovery, formatting data, wiping cache, davlik cache, system, internal storage. I did the factory reset. When I reboot, nothing seems wiped or erased. I tried using the android toolkit and installing the stock JWR66Y boot image from fastboot mode. When I restart, nothing has changed . No apps or data deleted.

I have pulled all my data via adb pull. It seems i can read data but cannot delete or write data.

I also tried Flash stock + unroot from NEXUS ROOT TOOLKIT 1.8.8. But even though it shows everything completed. All the data is intact in the phone and no new data is written.

Here is the log after Flash stock + unroot from NEXUS ROOT TOOLKIT 1.8.8

Booting up your freshly flashed stock device...

------------------------------------------------------------------

Wait for your device to finish booting up...

- It may appear to be boot looping; just wait...

- It could take 5-10 minutes; please be patient...

When its finally booted back up, please remember

to re-enable USB debugging if you plan on using

the toolkit to perform other operations.

NOTE: If this process was too quick and your device

is still in bootloader mode, then flashing stock may

have failed or been incomplete. Simply check the

log above: if you notice it skipped steps because it

didn't meet certain requirements, like the bootloader

or baseband version, then consider enabling 'Force Flash'

mode in the toolkits options menu and trying the

'Flash Stock + Unroot' processs again. Cheers.

Press any key to exit...

Anyone knows how to pretty much reset my phone because it seems as if I can't even erase data? Is my sdcard dead. Is there any way to fix this issue??
