Finally! The official Android 5.0.1 Lollipop update on Samsung Galaxy S4 GT-I9500 is now available for grab. The first official firmware build I9500XXUHOA7 or LRX22C.I9500XXUHOA7 is sent out in Russia at this moment.  Thought it was just another leaked version like the previous Chinese firmware I9500ZCUJOA3 but the latter is now officially send out by Samsung. So those who might have been waiting the official Android 5.0.1 Lollipop update you may try it out now.

In addition, it seems that the Android 5.0.1 is much stable compared to the Android 5.0 due to the facts that there are still some issues along with it. But, here's another real deal, the Samsung Galaxy S4 do not have any Android 4.4.4 and Android 5.0 updates. Hoping that it could worked better in the long run without any severe problem.  The only main culprit of the lollipop update lies in-between the incompatibility of some outdated apps. . While mostly, the Android Lollipop OS itself is very impressive when it comes to usability, looks and design.

  • Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB data cable.

  • Use the supplied USB cable for your Samsung Galaxy S4.

  • Enable USB debugging from your phone’s settings – Settings>>About Phone, then scroll down to the build number and tap that number for around 7-times ’til the Developer option appears. Hit back to Home>>Settings>>Developer option>>Enable USB debugging.

  • TURN OFF the Reactivation Lock – This is only needed if you already turned-it-ON, from which you cannot modify the system when it’s turned-ON. Go to Settings>>Security>>Reactivation Lock and then uncheck the Turn Reactivation lock on.

  1. Hi Ms. Wilma Dee, my s4 is still running on 4.3 firmware is it really necessary to check the "Phone Bootloader Update"??? And why??? what if i did not check the "Phone Bootloader Update" what will happen??? Thanks, hoping for your quick reply. you can also email me for your answer nolascojunelle@ymail.com thanks godbless.

  2. Q: If you did not check the “Phone Bootloader Update” what will happen?
    A: It will successfully flashed or you get failed, just between the two. It only depends on how the new bootloader reacts to the old bootloader. If you get failed then you should try to check that option. In most recent JB, KitKat, Lollipop has security patches which is hidden in the bootloader. Noting that a single stock (official firmware) doesn't mean that it does not have a bootloader, along with the AP,CP and CSC images when you flashed it in AP/PDA button. So therefore it will also updates the bootloader which occurs during flashing. So it is not a big deal when you have that option checked or not as long as you are flashing an official firmware.

  3. Hi , did you try the firmware?. India or Russia?, which one better?.

  4. I'm running hyperdrive Rom at the moment on a Galaxy S4 sch-i545 with T-Mobile. I brought it over from Verizon. Can I flash this firmware at all? Will have have to revert back to a stock Verizon Rom, and then flash? Is this firmware compatible with Safestrap? Thanks.

  5. This isn't for Verizon Galaxy S4 sch-i545 its's for international S4 gt-i9500.
