Small update E980

Fixing CWM Recovery loop...

dmw_4814 said:

O.K., I tried installing this update, and it booted into my CWM recovery, and now every single time I try rebooting the system, it goes right back into CWM. I've tried powering it off (instead of simply rebooting), and I even pulled the battery, but no luck. It still boots right back into CWM.

Anyone have any ideas? I'd prefer not to have to do a factory reset, as I have some text messages from a woman I just started dating I really don't want to lose (I know; I should've done a backup, at least of my text messages, before attempting to install this update - my bad)!

Just using the above post as an example ....

YOU DONT HAVE TO GO BACK TO STOCK OR ANYTHING....!!!!
The fix is very simple for the CWM recovery loop. I though I was a goner but some googling brought the answer quickly. Dont be put off by the steps: It is very quick.

After fixing the phone, to check if this was a fluke, I reinstalled the software update and fixed it a second time. So it works.........

1.a. If you are stuck on CWM OR TWRP boot loop DO NOT DO ANYTHING YET to the phone or anything. All you need to do is delete the "fota" file.
1.b. YOU MUST HAVE ADB INSTALLED AND WORKING.
1.c. Open cmd prompt as admin and run "adb devices". If you get
"List of devices attached
XXXXXXXX recovery" GO TO STEP 7.

If you HAVE adb installed and get no device output....continue from 2.
Otherwise, INSTALL ADB.

2. With the phone in CWM plug it into the computer.

3. Your computer MAY not see the phone. i.e you will get the ping noise for USB cnnection, but if you look under
COntrolPanel>>>>DeviceManager you will see a yellow exclamation mark. The next part I figured by trial and error.

If your phone is seen properly go to step 5.

4. If 3: although I installed the drivers again, if you had the phone working on adb before try this step:

4.b. Press and hold the Volume DOWN (volume decrease) button and hold the power button.
NOTE: I am not 1000% whether volume up or down did it. Try each one.
HOLD until the phone goes off and reboots. After the LG logo release the power. You will see black and white text as the phone tries to go into factory reset. It will ask if you want to factory reset...... SAY NO by pressing volume down button. During reboot my computer saw my phone and installed the driver. Phone was still on CWM recovery now.

4.c. If 4.b. did not work reinstall following drivers (attached rar): I do not know which worked, if any :silly: :laugh:

5. These steps I got from this forum post here: I DO NOT CLAIM ANY CREDIT http://forums.androidcentral.com/t-lg-g2/343661-help-please-lg-g2-stuck-cwm-boot-loop-2.html

6. Open cmd promt as administrator.
7. Run "adb devices"
You will get
"List of devices attached
XXXXXXXX recovery" Now yuor good to proceed

Enter: one by one

adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

""it will say xxxx info in and out or soemthing"" each time.

Type "exit" to leave adb shell.

Then "adb reboot". This will reboot your phone and all is great !!

For those that want the update indicator to go away... Just freeze the system app 'software updater' with TIBU or your weapon of choice. That's what worked for me.

Here is how...

This how i was able to have the new update plus root and cwm recovery. i applied the update and had the same issues that others had with boot looping into recovery. Called it no joy and had to use lg flash tools to go back to original stock. this did not work as well as the the software updater informed me that there was no new update. Used flashtools again but this time went back to stock using e98010k .tot file. now after being back to stock here is what i did.

1. Booted phone but did not sign in to any accounts or anything.
2. Rooted phone using universal root.
3. Booted phone and again did not sign in to any accounts. I also did NOT freeze any AT&T apps.
4. Connected to my wifi and checked for software update which was there and proceeded to download and install.
5. After download, the phone rebooted and installed the new update.
6. After the the update was completed and phone booted my version is now e98010p and i still had super su installed.
7. I then signed in to my google account and installed TIBU and freegee. both asked for root and was granted with no problems.
8. I then Used freegee to install CWM and rebooted phone with no issues.
9. I then used TIBU to reboot into recovery and that was perfect.
10. I then rebooted the system from recovery with no issues.

so i now have the latest update with root plus CWM recovery and now i am using TIBU to reinstall all my apps and an app called backup to gmail to restore my text messages.
This is what worked for me. Hope this helps.

It won't install if it detects root. At least not for me.
