I have also tried to "update from cache" never finding a recovery option.BLU Studio 5.0 II - Specification General zip file I loaded because it is only recognizing the internal storage as sdcard 0 and never sees the external sdcard 1. In recovery I have also tried to "update from sdcard" and I load the zip onto my sd card using my PC then I insert the sd into phone and boot recovery then I choose "update from sdcard" and i navigate thru the file tree never finding the. I have tried countless other files ADB Sideload and SP FLash no change. Kitkat update files for 4.4.2 to 4.4.3 same outcome and update files for 4.4.3 to 4.4.4 same. this file will sideload to 100% then the android stands up and then falls down and the upgrade is aborted.Ĭ: KitKat update files for 4.4.2.zip loads all the way then makes it about 50% thru the update then the android falls and it is aborted File will start to transfer and will reach 76% and then stop and hang indefinitely then give a "fail to read" error.ī: kitkat-4.4.4-FULL.zip.
I also tried flashing the phone then booting into recovery and running a "wipe data/factory reset" no change.Ģ) In recovery I have also tried "apply update from ADB" using this I was able to start the file transfer "adb sideload " with the following files and results.Ī: BLU_d690u_STUDIO-5.5-C_4.4.2.zip. I then tried to reboot the phone and still boot loop no change, I am going to speed things up here, I tried both flash tools, using every available command and sequence, almost every time I ran the program it was a successful load but no change to the phone.
Next I disconnected the phone from the PC and in the SP Flash I selected DOWNLOAD and then connected the phone to the PC and the download started and completed without errors. Once I had communication with the SP Flash Tool, i found the stock ROM with a scatter file for use with the SP Flash Tool at the Need Rom website I started with the new version of SP Flash Tool 5.0 and I loaded the scatter file found in the unpacked ROM file into the flash tool and started a FORMAT using the Automatic setting then with the battery removed I connected the phone USB cable to my PC and it started the process and completed successfully. I have a BLU Studio 5.5c running the stock Kitkat 4.4.2 ROM that just refused to turn on one day and has been stuck in boot loop for about 8 days, these are the steps I have all ready taken that have failed.ġ) boot device into recovery and "wipe cash" then "wipe data/factory reset" then reboot system, this has no effect at all.Ģ) Installed ADB Universal Drivers and SP Flash Tool both ver.
