Lock Screen Issue

Hi,

I used the following steps to update my MK2 rooted unlocked AT&T S4 phone to NB1.

I337UCUFNB1_Stock_Rooted_ROMwTethering

1. Place the ROM zip in the root of your ext sdcard.

4. Boot into Safestrap recovery, perform an advanced wipe and wipe everything except ext sdcard.

5. Flash the ROM zip in Stock Slot.

6. Press "Home," then reboot into Download Mode and flash the I337_NB1_StockPartitions in PDA slot in Odin.

Once complete the phone will apply an update to cache, then reboot and pause on the white AT&T splash screen for about 1-2 minutes before completely booting into the ROM. Done!

However, after completing the above, I cannot lock my screen. I saw the following known issue:

Known Issue: If you have never updated from MK2 to NB1 you may experience an issue with lockscreen settings. The issue can be resolved by flashing the FMLD_Bootloader in Odin. You will still be able to revert back to factory stock MK2. NB1 users should not flash this file as it may hardbrick your phone.

Can I flash the phone with the above file? If Yes, should be go into the PDA slot or Bootloader slot?

Please help me resolve the lock screen issue. Thank you.

Try rebooting your computer and trying again. You can also try Odin v.3.08 which is the version I use. Flashing the FMLD BL should resolve the lockscreen issue.

well I figured out what happened and it wasn't anything wrong with what you posted or what I did
it was my ******* front usb port on my PC
maybe not enough power is the only thing I can think of.
I was just about to bail and go to best buy and have my buddy redo my phone
and I thought let me try moving this cable to the motherboard usb slots
and wala! it flashed without a hitch
if anyone else has this issue ,try swapping usb cables locations
thank you very much !!

No MD5 File Found error

1. Download the MK2toNB1_KeepRoot_OTA.zip and place in the root of your ext sdcard.
2. Follow steps 2 -3 from Post#1 to downgrade from NB1 to MK2, root, and install Safestrap.
3. Boot into Safestrap recovery but Do Not Wipe.
4. Flash the KeepRoot.zip in the Stock Slot and once complete press "Home" and reboot into Download mode.
5. Flash the NB1_Stock_Kernel in Odin's PDA slot.

I'm on AT&T I337 Stock MK2 Rooted / SS 3.71 and when I go to flash the keepRoot_OTA zip in SS I get "MD5 file not found. I know the MD5 file is there because I ran MD5 Checker & verified the hash and all matched. I'm on SS 3.71 Stock slot while trying to flash. Should I be on ROM Slot 1 when flashing the zip file to the stock slot?

Thanks in advance

No stock slot is the correct slot. I tested the latest version of the OTA.zip using SS v.3.72 and recommend using 3.72 exclusively. Try using v3.72 and let me know if that works. thanks

EDIT: make certain the "zip file signature verification" box is unchecked. There is no need to check sig.

I removed xposed framework and modules, will triangle away prevent the zip from flashing? Thanks again

HELP!

I've perused through several different threads.I'm following these directions and rooting and installing the ROM in the STOCK slot. That works and I end up with a rooted NB1 ROM.

I'm having issues installing GoldenEye 26 SS after this point. The instruction in the OP say in order to put another custom ROM I need to boot into SS recovery and advance wipe everything but external sd. I do this but when I install Goldeneye in the STOCK slot it boots up fine but after it boots I end up unrooted and no wifi. Any help you guys can give I would really appreciate. I hardly ever ask for help but I've tried everything.

@rebel1699 is the custom rom guru and may be able to help with GE.

    The following is not a root method in the "traditional" sense, e.g. Saferoot, Kingo. This is a workaround to our inability to root KitKat 4.4.2. However the end result is a Fully Functioning, 100% Stock, Rooted, NB1 Device. (See Post# 2 for "KeepRoot"OTA.zip Method). Proceed at Your Own Risk! (Thanks to @ted77usa @rebel1699 @Maribou @dave5777 @dolph8886 @Surge1223 @jeboo for discoveriing it was possible to downgrade from MK2 to NB1. Special thanks to @rebel1699 for figuring out how to flash a 4.4 SS Custom ROM on our device. Without them this workaround would not be possible).


    **Closing my thread now that a direct rooting method is available. Congrats to Everyone mentioned above for your accomplishments while we waited for this!** : http://xdaforums.com/showthread.php?t=2783157


    **Note**: The process below has been proven to work without exception when the instructions are followed to the letter. Should you run into trouble please consider re-reviewing the instructions to identify your error before requesting assistance. Thank you.

    Get the latest I337 firmware here: I337UCUFNC1


    Donations Welcome!




    Here it is: I337UCUFNB1_100%_Stock_Rooted_ROM

    And here: I337UCUFNB1_100%_Stock_Rooted_ROMwBL (This version contains the NB1 bootloader. MK2 bootloader users will not be able to go back to factory stock MK2 after flashing).

    1. Place the I337UCUFNB1_100%_Stock_Rooted_ROM in the root of your ext sdcard.
    *2. Download the I337_Downgrade_to_MK2 file, extract the .tar and flash in PDA slot in Odin(AP in Odin v3.09+) to obtain semi-functioning(no-wifi) MK2.
    3. Use your favorite root method to root MK2, e.g. Saferoot, Kingo Root App, then install the latest Safestrap-JFLTE-3.72-kk-B01.apk.
    4. Boot into Safestrap recovery, perform an "Advanced Wipe", and wipe everything except ext sdcard.
    5. Flash the ROM zip in the "Stock Slot." Once complete press "Home," then reboot into "Download Mode".
    6. Flash the I337_NB1_Stock_Kernel in PDA slot in Odin(AP in Odin v3.09+).

    *MK2 users can skip Step 2.

    Once complete the phone will apply an update to cache, then reboot and pause on the white AT&T splash screen for about 1-2 minutes before completely rebooting. Done!



    - MK2 users can use Safestrap's Backup/Restore function to backup and restore User Data prior to and after flashing the ROM. Make sure and thank @loganfarrell for discovering this very useful feature.
    - In general, to flash a different 4.4.2 Safestrap Custom ROM after flashing this ROM reboot into Safestrap recovery, perform an advanced wipe, and wipe everything but ext sdcard. Then flash the new ROM in the "Stock Slot" and reboot (Refer to the other ROM's dedicated thread for any additional requirements or for assistance. Please limit the discussion in this thread to the 100%_Stock_Rooted_ROM and the KeepRoot OTA zip).
    - To go back to factory stock, un-rooted NB1 flash the NB1 4.4.2 Stock Odin .tar in the PDA slot in Odin(AP in Odin v3.09+).
    - Those that never took the MK2 to NB1 update can return to factory stock MK2 by flashing the MK2 All-in-One Full Odin .tar in PDA slot in Odin(AP in Odin v3.09+).


    Known Issue: MK2 bootloader users will experience a lockscreen settings issue. The issue can be resolved by flashing the FMLD_Bootloader in Odin's PDA slot(AP in Odin v3.09+). You will still be able to revert back to factory stock MK2. Caution!: NB1 & NC1 bootloader users should not flash this file as it may hardbrick your phone.





    I337UCUFNB1_100%_Stock_Rooted_TetherAddOn
    Instructions:
    1. After flashing and booting into I337UCUFNB1_100%_Stock_Rooted_ROM,
    2. Place the AddOn in ext sdcard.
    3. Reboot into Safestrap recovery and flash the AddOn in Stock Slot (Do Not Wipe Prior to Flashing)
    4. Reboot. Done!

    I337UCUFNB1_MK2-to-NB1_KeepRoot_OTA.zip Method

    This alternative "Keep Root" method uses a modified version of the official MK2 to NB1 OTA Update.zip to upgrade while maintaining User Data and Root Access! The file is flashed in Safestrap and the end result is a 100% Stock, Rooted, NB1 Device. Proceed at your own risk! Thanks to @jeboo for giving me the idea to develop this method!

    **Prerequisite** This method requires that your MK2 system is 100% stock except for root and Safestrap. The update will fail if any MK2 system files have been modified or deleted, e.g. thru Xposed, etc. You must first restore the stock files or reflash back to stock MK2 and re-root.



    Here it is: I337_MK2toNB1_KeepRoot_OTA.zip

    And here: I337_MK2toNB1_KeepRoot_OTAwBL.zip (This version contains the NB1 bootloader. MK2 bootloader users will not be able to go back to factory stock MK2 after flashing).

    1. Place the I337UCUFNB1_MK2toNB1_KeepRoot_OTA.zip in the root of your ext sdcard.
    2. Follow steps 2 - 3 from Post# 1 to downgrade to MK2, root, and install the latest Safestrap-JFLTE-3.72-kk-B01.apk .
    3. Boot into Safestrap recovery but Do Not Wipe!.
    4. Flash the I337UCUFNB1_MK2toNB1_KeepRoot_OTA.zip in the "Stock Slot" and once complete press "Home" and reboot into "Download Mode".
    5. Last, flash the I337_NB1_Stock_Kernel in Odin's PDA slot(AP in Odin v3.09+).

    Once complete the phone will reboot to the white AT&T splash screen then "optimize apps" before completely rebooting. Done!




    Known Issue: Safestrap.apk will force close after updating to 4.4.2 using this method, however Safestrap recovery will continue to function. Optional: to manually uninstall Safestrap recovery use Es File Explorer to delete system/etc/safestrap and system/bin/e2fsck then rename system/bin/e2fsck.bin to e2fsck (save these files if you wish to manually reinstall Safestrap at a later time).







    I337UCUFNB1_100%_Stock_Rooted_TetherAddOn
    Instructions:
    1. After flashing and booting into I337UCUFNB1_100%_Stock_Rooted_ROM,
    2. Place the AddOn in ext sdcard.
    3. Reboot into Safestrap recovery and flash the AddOn in Stock Slot (Do Not Wipe Prior to Flashing)
    4. Reboot. Done!

    I'm guessing that this is for both NB1_Stock and NB1_Stock with tethering ROM? To flash the NB1 KernekModules.zip

    Sent from my A210 using XDA Premium 4 mobile app

    Just an FYI, the NB1 modules are built into the ROM, so there is no need to reflash them or push them into system.

    Just a quick update: earlier today I got my S4 running rooted and running 4.3 with Safestrap and the Wifi antenna fix. It's been working like a charm, and I can finally get full use out of my phone. The whole process was a bit more agonizing that I was expecting, but the important thing is that now everything works the way I want it to, and I am loving it. You guys are the best. :good:

    So happy this worked! Great job to all who made this possible! :)


    I'm testing an alternative root workaround method which, for some, may be an easier process. It looks promising but we shall see........

    thanks for that info. i see theres quite a lengthy and technical thread on unlocking. ill have to keep an eye on that. i did manage to find a 2gb sdcard thatll work for now. if xposed works fully, ill be happy for now. but bootloader will need to be unlocked for future updates past kitkat and when att stops providing updates. if i know att, this may be the last update from them...

    Oh to get rid of the startup noise, after installing this rom, use ES Explorer to navigate to /system/media/audio/ui and find PowerOn.ogg . Rename it to PowerOn.BAKogg

    Now your phone cannot find that obnoxious sound when it starts up and will be soothingly silent.
