Finally unstuck but now autoresets

My phone did not want to boot this morning after swapping SIM-cards twice. Tried many things, including a hard reset, but nothing worked; the phone kept getting stuck in the second boot menu (with the fancy coloured X). When I tried to leave it it took a few minutes but the phone finally booted.
But I lost all settings (not files luckily) and came into an unknown screen. Had to setup a Google account but could not do that before accessing for internet. All these things work again, but when I reboot the phone it seems to reset again and I have to start from this unknown screen again.
Does this sound familiar and what can I do about it?
By the way, the phone currently runs Android 2.3.6 so there are no official updates (right?).

I've been messing around a bit and the "unknown screen" seems to be the new initial Android screen, in which you can setup the phone (Google account etc.). Strangely enough the phone keeps resetting and I cannot change anything. Even formatting, either through Windows or the boot/root menu doesn't help: all files that are on the phone right now are kept. I cannot add new files either.

First of all, do you have a Nexus S, or Nexus S 4G? Is your bootloader unlocked? If not then I suggest you follow the guides in the development section. I can't put links due to still being 'new' on here. Find a recovery, flash via fastboot, boot into recovery and flash a rom to your liking. Or you can find some system images and flash via fastboot. I hope this helps. If not, then you can pm me and then I will show you how.

Thanks for your reply. I did not unlock the bootloader. I've seen many difficult topics and don't really know where to start.
I just found out that the phone not necessarily resets to a previous state (this morning) but seems unable to write anymore. I just hooked it on to my PC, removed a file, disconnected, and upon reconnection the file was there again (whereas Windows really removed it).

I am uploading some files to Dropbox now. Its gonna take a bit. Then I will guide you through, step by step. Sorry for the wait. I know you want to get your phone back up and running. In the meantime, I recommend doing some reasearch here on xda. Don't be afraid of Google, either. Google can be your best friend.

Read it first. It might come across tricky or hard, but its not... Once you do that to unlock bootloader and root, I would advise you to download either a stock rom, or any others you may feel comfortable with. Look around. There are plenty here on xda.

Thanks again . A friend of mine was trying to help with bootloading and stuff, but it's somewhat obscure. He said that chances that it's software or hardware are just 50:50.
Got me kinda frustrated yesterday evening but I still have warranty on the phone (have it for half a year now). Problem is that it might be a hassle, because of a conflict between the shop and the provider. But that should work out.
In the meantime it would be nice to try and get it running again.
Strangely enough, the phone drained itself this night. I made a basic install yesterday and left it in standby. This morning, when I checked the phone, it didn't do anything so I thought it finally passed away. Now that it's hooked to my computer it's charging, and it seems to start from 0 (starting with 0 bars of the battery).

Via your link I came to the following guide, which worked partially (cannot link it here).
age tee tee pee ://jaxov.com/2011/02/how-to-root-android-2-3-3-gingerbread-on-nexus-s/
I got up to step 13, where it seems that I cannot find the .zip-file because the phone doesn't store new files...

You can wait for warranty, or you can follow this guide:
http://forum.xda-developers.com/showthread.php?t=947950&highlight=odin
Odin will flash it back to stock without the need to put files on your sd card. Just download the odin files, open up odin, put phone in download mode, and happy flashing. You have to be careful with odin, though. Follow the guide. If you need help, then let me know. I can probably do it remotely for you.

Thanks, I'll try that tomorrow (topic doesn't seem so clear at first glance).

According to this guide, I have to start in Download Mode. I can access this by holding Volume Up + Volume Down and then plugging in the USB cable. It works, but the phone will not be updated and I'm stuck with the "Downloading..." message. Also, Windows Device Manager sees a Gadget Serial, which I cannot update. Google didn't allow for a clear answer (Samsung PC Studio 7 didn't work).
I also think I have an i9023, because it's the European version (which SHOULD be with an LCD screen).
By the way, I just tried formatting through Windows (FAT32) and if still connected the phone indeed seems to be empty. But as soon as I disconnect USB storage all files (on the phone) are back. Nothing special because the problem is very consistent.

Update
Alright, I finally got the drivers properly installed (also to work in Download Mode) and found proper Bootloader/PDA/CSC files (i9023EUR) for Odin and managed to do the flash update (however Odin I used is called I9003_Odin3 v1.82, don't know if that is a problem).
Then I should do a factory wipe, which works (Bootloader -> Recovery -> Wipe), but if I explore the phone I can see that all data is still present (all images, music, etc). So the hard drive still seems fixed.

Please help me out, guys...

Suggestions? Or unfixable and should I send it to be repaired?

I found out that I did not post my last update. I managed to flash with Odin, and I can get into the Bootloader menu to wipe the phone's data. I can, in Recovery Mode, also see the hard drive and it seems to be empty. That is, the phone fails to see it.
When I reboot out of Recovery Mode the phone gets stuck at the Google logo and that's it..

Ok, I will send the phone to be repaired. The phone is now unrooted and does not go further than the Google load screen.

Do you have fastboot? If not then download below.
http://dl.dropbox.com/u/64632729/platform-tools.zip
Extract contents to desktop. Open up a command prompt:
cd Desktop/platform-tools
Put phone in bootloader mode. In command prompt type:
fastboot oem unlock (only if your bootloader is still locked). If its unlocked then download this
http://dl.dropbox.com/u/64632729/recovery-clockwork-5.0.2.0-crespo.img
Put in the platform-tools folder you extracted earlier. Then type in command prompt:
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
Sometimes the flash might say 'fail' if that is the case then just boot the recovery image by typing:
fastboot boot recovery-clockwork-5.0.2.0-crespo.img
Now boot into recovery and flash either a stock rom, stock rooted rom, or whatever your desire is.
This should work. If not, then there has to be a hardware issue with phone and go ahead and send it in for warranty. Let me know if this helps.

Flashing Clockwork did work, but if I understand correctly I have to copy the stock rom to the phone and load it in Recovery Mode? When I connect the phone to my PC it is recognized as an Android Phone (and even as a Nexus S) but the drive it shows up as seems to be recognized as empty ("Please insert a disk into Removable Disk (E.").
So what do I do?
What is sort of promising is that it indeed was capable to flash Clockwork. So the memory is not completely stuck. However, when I do a format, still nothing happens (phone isn't formatted).

Update: I am able to mount the phone to USB and I can access the phone via Windows. However, I can still not format the SD Card (which is of course internal) or put files (stock rom) on it. Are there other tricks to flash a stock rom? If not, it does indeed seem to be that I cannot flash a custom/stock rom because the drive of the Nexus is frozen/broken/whatever.

Help?

I did this: http://forum.xda-developers.com/showthread.php?t=2046439 then attempted to put CM10(http://forum.xda-developers.com/showthread.php?t=1840414) on the phone. I downloaded the stable version for Verizon wireless and made sure it was correct etc. I went to TWRP and put install then went to the .zip and continued after doing that the phone resets saying "System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help.". I am not entirely sure what I did wrong but it will no longer let me enter twrp but it does let me go to the download screen. Did I brick it or what? Thanks.

You didn't brick it I had that pop up my first flash as well
Pretty sure It was because it didn't unlock the bootloader correctly.

How do I use odin to put the bootloader file on my phone since it's not an .md5 file etc.? Sorry, just don't understand.

" I held volume down/home for a few seconds and then held power. The phone booted to a mode I had not seen before (recovery/download as you said?) and I said cancel and the phone booted!"
Boot normal. use tool in first link to unlock the bootloader and CM should be up and running
---------- Post added at 02:00 AM ---------- Previous post was at 01:58 AM ----------
also you should be able to get into recovery just let go of the volume, power, home as soon as you see the samsung logo pop up

I did the hold the volume button down/home at same time then press power but that sends me to the normal do I want to download press up to continue or down to cancel. I pressed down and it still gave me the warning. I try going to recovery but it prevents me by telling me the same message. I think it's the bootloader like you said but I don't understand how to get the file on the phone through oden. I downloaded that first link but it won't go through oden because it's not the .md5 etc and the computer isn't showing me the phone data through my files.
I am going to odin flash a stock image then re-boot.

I reflashed the phone using odin. I went through and used the "casual" rooting process which appeared to work. I went into twerp then pressed install then pressed the .zip for the CM mod. It re-loaded and now it's stuck on the CyanogenMod screen with a circle. I don't understand if it's installing or what?
I understand now why it wasn't working. Answer in here: http://forum.xda-developers.com/showthread.php?p=36341274 Anyways, now that I got CM to work. GAPPS refuses to work, it sends an error message saying that the Setup Wizard has failed. I don't understand that.
Checked to make sure the GAPPS version I downloaded was the one compatibale with the CM version, it was not so I re-downloaded the correct version now everything is working great. Thanks spitfire143 for all the help and getting me on the right track!

[GUIDE] How to recover from OnePlus soft bricked?

I decided to write a guide on how to recover from a bricked OnePlus One. This is my first guide.
About me: I am a newbie on Android.However, the XDA community has taught me a lot about my Android phone for the first month of using it. That's right! I have only been using Android for less than one month so take this guide with a grain of salt. But if you happen to soft brick your One, this is the guide to turn to. I have created two mind-bending/heartbreaking/frightening scenarios that I have experienced. Though, resolved thanks to this community.
Note: This will wipe your phone!
Scenario 1:
Soft bricked, (CM gear keeps spinning but won't boot to lock screen)
Scenario 2: Updated kernel on a non-compatible firmware.
Soft bricked, screen on 1+ logo and won't boot to lock screen.
Solution:
1. Download the toolbox from: (Make sure you download your version)
http://forum.xda-developers.com/oneplus-one/development/toolbox-oneplus-one-toolbox-t2808987
2. Install the file.
3. Disconnect your OnePlus One from computer and power off your phone.
4. Go into Fastboot Mode (Volume Up + Power button) wait on vibrate
5. Plug in your OnePlus One.
6. Locate and open the OPO Toolbox.
7. Click Flash CM XNPH22R.
8. You should see command prompt open, just wait until it finishes doing it's thing.
9. Unplug and power off your phone.
10. Power ON your phone and wait until it prompts you re-setup your phone.
Congrats you have just fixed your phone from a soft brick. Simply follow the video from the link provided on step 1 to re-root your phone.
Note: If you have unlocked your bootloader, you do not need to unlock it again.
How to find out if you have unlocked bootloader:
1. Locate the folder where you installed the OPO Toolbox.
2. Hold Shift and right click on ANY white area within the folder.
3. Left click 'Open command window here'
4. Type:
fastboot oem device-info
If it returns True on tampered. Then you have unlocked your bootloader.
I hope this guide helps solve your soft-bricked problem. Good luck!

I suggest that a mod moves this to the General section

I did an ota update and it went in to a boot-loop, so I went into fast-boot and accidentally locked the boot-loader.
I think I have to try to hard-brick it and try the hard-brick solution with the qualcom drivers.

Then first you need to unlock the bootloader via fastboot,but that action erases all data. I assume,if you modified the boot via fastboot, USB DEBUGGING is working,so after try to do the softbrick tutorial of the thread.

Is it a way to force the bootloader unlock ?
Please HELP !!!

Didn't work for me
I'll give the background first as it might help. I long while back I did a manual upgrade to CM12s using the guide in this video "How to Install CM12S on OnePlus One - No Root or TWRP Required, No Data LOSS" from the oneplus exclusive Youtube channel.
It worked great no problems.
I recently I got the OTA update to CM13. There were several features I didn't like so I decided to go back. I repeated the process shown in the video but now my phone gets stuck on the CM logo screen and won't go past. I tried again but the same result. Then (I can see heads shaking, sorry) I tried a factory reset from the recovery screen, still the same goes past the 1+ logo but gets stuck at the CM logo. Then I found this guide, downloaded the toolbox but when I try to plash it says "fastboot is not recognized as an internal or external command.
Any ideas?
Found a link on one of the threads here that said a guide on Reddit was useful, that didn't work as well. I am trying.

[Q] im in dire need of help please!

Here is the rundown. I have the d 850 LG g3. Was planning on unrooting phone from towel root and rerooting it using towelroot once I found the mod I wanted. I have the latest version of twrp loaded as well. On my way home from work yesterday I was riding my motorcycle and listening to music, all the sudden the music stops so I pull over to see what happened and look to see that my phone has somehow opened twrp. I get home and try to reboot phone and it loads right back into twrp. I did a backup. Restarted phone to same results. I factory reset phone thinking that would work. NOPE. Straight back into twrp so I plug phone into computer to see what's on it. It appears all my games music LG backup etc is still there's why can't I get out of twrp. Could I have accidentally wiped everything while in my pocket? Can I fix this problem or do i now have a $500 paperweight? Please please folks out there in xda land help me out. I've got experience in rooting with my htc m7 so am familiar with this stuff. Any help would be greatly appreciated. Thanks for your time.

Somehow your rom partition/system seems to be corrupted. If you want to try and save your data, Please copy the downloaded version of your current rom and dirty flash (flash without wipe) and try to get back into the system. If you do not have your rom in your internal memory, try adb sideload or try to copy it to your external SD card and install from there.
You can also try to copy your stuff over to the external SD card using the file manager in TWRP and then wipe and install your rom.
If none of these wor, you still can flash factory image by process defined in the this thread: http://forum.xda-developers.com/att-lg-g3/general/unroot-return-to-factory-stock-att-lg-g3-t2820827
I believe you can still rescue your phone. Please let us know how it went.

I tried flashing a ROM with gaps and rebooted and it still senT me back into TWRP.

Maybe his phone tried to download and install the OTA? Try this also if the above doesn't work. http://forum.xda-developers.com/lg-g3/development/fix-stuck-custom-recovery-trying-ota-t2907508

If you already tried to flash a rom (other than your current one) I suggest you try the "back to stock" thing that was referred in my last post. If you have all the drivers in place and do the process correctly (preferably from a Windows 7 laptop), Your phone will be burst back to life in no time.. Good luck..!!

That is exactly what you want. You are now in download mode. So please proceed to next step (i believe the next step is on the laptop).

But the firmware update hasn't even gotten to 1% yet and I don't know how to get back to download mode. I don't know if unplugging device and trying again will mess it up even more. Device manager didn't pop up on computer either

Device manager wont "pop up".. you need to pull it from control pannel. Once you confirmed/changed the port to 41, i believe you can pull the usb, wait for 5 sec and put in back in. Follow exactly as instructed in the thread and you should be fine.

Also firmware update starts after the "usb pull" and re-plug in.

I haven't gotten a chance to pull it up. IT goes to download mode and then right into firmware update. I'm looking on control panel for my phone so I can go into port but its not showing up in control panel

1) The "firmware update" page is the download mode.
2) Control Panel -> Device Manager -> Ports -> Select LG one -> Port Settings -> Advanced -> look for "Com Port Number" on left hand side.

If your device does not show in the Ports section, that means that your drivers are not installed correctly. Did you install the one given in the thread?
---------- Post added at 04:39 PM ---------- Previous post was at 04:32 PM ----------
Try these drivers if you cant find the right one: http://www.koushikdutta.com/post/universal-adb-driver

Yes drivers showed in port. Followed instructions according to LG flashtool and in getting a message saying that lgusb/ parallel lock key is not detected

At what stage of the process are you getting this error? Please refer to the step number in the "back to stock" thread.

Lg flash tool is saying authentication failed

Re-try.

Again, at what stage did you get the error? Which step?
Did you install the driver i quoted above? If you did in between the process, please pull the battery and try from the beginning if the flash process did not start.

Did you replace the DLL file in the folder as instructed? Did you give the computer's correct admin password? Are you logged in as an admin in the laptop?

SECURE CHECK FAIL:SYSTEM any way to fix it?

So i bougth an used S8+ (g955u) which seems to be from verizon. the thing is that right on the first boot i put in my simcard(AT&T) and microSD card, the phone booted whit a verizon screen then on the first settings screen a windows pop-up told me to reset it, cant remember why, but i tap on yes, after that the phone reboot again but now with an AT&T screen, i was unable to pass the fist settings due to playstore stopping everytime after the wifi setup, so i took out the sim card and skip the wifi setup and finally get to the home screen. but the problems dont end there cuz some apps were forceclosing when i tried to open it (internet browser, playstore even i was able to log in with my account tho) and some times when i reboot the phone it get stuck bootlooping until i force a shutdown and turn it on again... now here start the part where i need help i tried to flash another software version whit odin, but no matter what uptdated or outdated the phone says: Secure chek fail:system even whit the version it supposedly came, im on bootloader 5 i think and now im stuck on download mode. is there a way to flash a stock or custom firmware or should i let it die?

Hmmm i would start with the latest firmware. If that fails maybe flash the latest combination file then firmware.
As for verizon att. These device normally now are multi csc selects system based on sim inserted which is awesome when it works right. But oreo and up i think checks system integrity so i would start with the combination files bit 5 then firmware

Thanks, I've tried that already. Android 9 version, the B5 combination files. Even flashing every file one by one the problem is with system. Idk why but fails at the last second, I'm thinking in use the repartition option in Odin but I'm afraid it could get worse

The thing is that to reboot into edl seems that first I have to be able to boot into system or a composition rom, Wich I'm unable to cuz the phone doesn't let me flash the system partition

Lol i just responded in the other thread. If you dropped it take a bright flash light on the screen and inspect for any cracks under the gorilla glass. Sometimes the oled can crack without the outer glass breaking. If not. Try bixby vol down and power for upto 20 sec
