So my phone is a carrier phone (SM-G925F) that is sim unlocked (I think it was using a code). I had rooted it a few days ago with cf-auto-root and had to do a wipe cache partition cause it was stuck in a bootloop. After this everything was fine, made sure it was rooted and backed up with Titanium. Today I was trying to set root access on ES File Explorer but it was giving error, reinstalled app and nothing. So I stupiditly thought that maybe I needed to clean chache partition, after all I had done it once and there was no problem. But this time, after rebooting it will say that SIM card is invalid (Network locked SIM card inserted) and asks for a unlock code. Can please someone help me? I've looked for similar errors but havent found any solution.

Hi,
I'm running stock ATT 4.5.91 plus root applied. Just some minutes ago I tried to install Opera Mobile from the market and during installation the phone rebooted. After that, the system keeps rebooting at the unlock screen (all I can see it is mounting the storage system).
I tried wiping cache from stock android recovery but it still keeps rebooting.
I guess a factory reset could solve the problem, but I'd like to save some data I have on the internal memory. Is there any chance of saving them?
Thanks in advance!

Not sure if the stock recovery allows it but can't you mount usb & then save whatever needs to be saved?
Stock recovery doesn't include that option. Still, I connected the phone to the computer and never happened.
you want to save the stuff thats on your "internal sd card" or data that is on the /data partition? if oyu do a factory wipe it asks you if you want to wipe internal sd or not, so if you want to save data form there you can do a factory wip and it shouldnt wipe it. Otherwise flash a service sbf (if you are on stock 2.3.4 with that bootloader, you can only flash the 2.3.4 sbf or eventually pudding sbf but than you need to unlock your device, which deletes your data, so the onyl option is stock 2.3.4 service sbf)

I just did the wipe data/factory reset and it left the internal sd card untouched, so that was perfect! I didn't know that this option just erases /data.
Now I'm going to unlock the bootloader and install a better recovery and CM7. If this is going to happen again, there is no point in remaining stock (at least in my case).
Thanks both for your help!
I tried to reset my phone to factory state but after i flashed everything.. all my files were still there..
I tried to format my sdcard internal&external, no good..
Tells me that its formating but nothing happens, and my external card isnt recognized any more by the phone just says "card is blank".
How do i fix this?how do i fully reset my phone and the sdcard?

Post belongs Q&A
TRY
Clean Slate for those that balls up the firmware .Or need to return to service or decide if its hardware/firmware problem .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .
Still problems use usb jig to set rom counter to zero .
Return to service centre .
I did the full wipe from cwm but didnt flash after it...
I will try it now an post result, thx.. any way

If you really want to wipe your device, press:
*2767*3855#
WARNING, there is no confirmation, when you pres the last digit "#", everything is gone for good... Make a backup first, this code wipes your whole SD and formats it to factory defaults, i "think" only the external sd is untouched, not sure, you'd better remove it before typing the code.
Hope it helps

Is there any different between this method (*2767*3855# ) and by going in to settings ->privat --> factory reset? If so, what's the different (im not sarcastic, i really want to know)
thank you,
from memory, a factory reset via android's menu only wipes /data and /cache (plus a few other things like the android_secure, .cache and sd-ext folders) but leaves your internal and external SD intact.
the service code is the "real deal" and wipes everything that's mounted. Why don't you try it and tell us the results? I hear lots of good about it... ^^

Nah, i leave it to someone els. Do you know if this method also erase the root or not?
nope, /system partition remains as is (including all the files that were installed to it, but there aren't that many of them. Most third-party files get written to /data, which is also wiped. There might remain a few .conf files in .etc though, but it's rarely a problem -especially for rooted users, since we're used to completely wipe everything including /system when flashing a new stock ROM )
Use the service code or as JJEgan said:
Boot CWM recovery,
go to Mounts and Storage,
Format cache, data, system and sd card.
^^both of these methods do the same thing and will wipe everything that has been changed by the user.
Good Luck.
I performed the *2767*3855# method but yet on first start up im still seeing a background from a old rom ive flashed to it? Why is this? Is there any way to completely nuke everything on the phone? and just start flashing things back onto it?
Help
Hi how do I completly set my phone back to original unrooted status?
I have read up on so much but I seem to have made a right mess of my phone.
I can't unroot it no matter what I do, I put the original kernal back on through odin but it is still rooted but it got rid of yellow triangle.
The phone works ok and boots up but even the usb jig won't reset the counter, just boots into recovery mode.
I'm at the point as I don't know what I have done anymore.
Please help someone.
A while ago, I decided to work on my old legend and upgrading it with new custom roms.
After factory reset, I have flashed CM10 rom from here and discovered my Hboot version is 0.43 and not compatible with this rom.
So I found this rom instead and made 3 different partitions as instructed. But I have discovered that my phone have lost ability to go to recovery mode during the process and cannot recognize the zip files from SD card although its still in there. I have reformatted the SD card again with one fat32 to see if its problem with partitioning but it is still having same problem.
I can see the red triangle with ! in it and selected "Apply sdcard:update.zip" which keeps giving me error message "E:can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0) Invalid argument"
Is there any solution to get out of this situation?
Thank you for your patience

I have followed this thread and I got an error message saying failed due to low battery. I will just charge the phone for a while and see if it gives same error.
I have done the fastboot recovery method from here and its keep giving me "failed (remote: not allowed)" messages.
my Legend is already rooted and currently on S-off.
I have solved the problem.
It was memory card problem. my legend works after installing CM7 using different SD card.
I am suspecting if its because I have messed up something with memory card while dividing partitions to install a Jelllybean rom,
However the faulty memory card is still functioning well on my pc which made me think there is no problem with it.
Hello, greetings to everyone here,
First of all i am sorry because of my lack of English vocab in typing.But i really frustrated within this bootloop problem in the end.
I have samsung SCH i759 , and i tried to root, 2 times, using Odin on first trial, after i downloaded Samsung USB driver, CWM md5.tar and SuperSU update.zip then failed and succeed when using VROOT, then installed android partition and Link2SD app in play store.I even created some links to move apps to SD card for more internal space.
works fine until few hours ago, i decided to change the partition space on Android Partition into 4 parts ,between FAT32 and then changing EXT4 into EXT 2 and adding exfat then swap, then i forget to unmount sd card before.
then i get error notification, then phone is lagging, then restarted.
Since then i lost apps i installed and moved to SD card.
then i decided to unroot Via VROOT PC. and then reset to factory , and now what i get is worse than before,
now phone is keep on recovery boot mode, i tried some advices on web, from keeping hard reset, take off battery, until wipe cache, dalvnik cache. etc. but something strange, when i enter the "Wipe data/factory reset"
the options list is just "NO" instead of "YES"
now,it keeps loading into recovery mode from samsung logo with yellow triangle below.
this is my last effort before i will send it to service centre. i really hope seniors here will give advice for this problem.

I'm trying to solve an issue with a J1 mini prime (J106B) that my cousin ask me to fix. She hit Encry phone and after reboot the phone won't continue booting due to encryption failed error so I ask her to factory reset in recovery. After factory reset we still failed to get the phone working since FRP lock is on ang gmail used on the phone is not ours. So I have to do a Odin flash, I got a official rom and flash AP. After flashing it kept all its settings and I can't install any app as storage says 92% of the storage is being used and it says the phone only has 4GB of storage. I have another J1 mini prime and doesn't show the normal storage.
Any idea why flashing kept all its settings and lost half of the storage and any way to get it back? I can't do anything with the phone. with less than 100MB of space left. Not even newly factory reset state as there is not enough space to install anything on it.
I totally forgot to update this this, I fixed it on the same day of posting this. What it was is that flashing the phone disabled the FRP Lock and there is an issue with phones losing 50% or more of its storage after disabling the FRP lock. Running factory reset once more fixed the issue. Sorry about that.
@Jerahya
That's weird because you only re-flashed Android's system partition ( AP ): the user space ( data partition ) shouldn't have been affected .
My guess is that the Factory Reset you did filled up the user space with lots of bloatware.

Factory reset does not "add" or install anything on android, it erases your settings and everything that has been installed by the user and leaves you with only the software that was already there before the user installed anything on the device. Factory reset in android is not like "restoring to factory defaults" on a PC, they are two completely different animals.
Besides, any factory bloatware contained in the stock OS would be installed in the system partition, not the user partition, it would not take any space from data partition, even if factory reset did re-install the bloatware during the reset, it would be in the system partition.
