[HTC Butterfly] kemikelx:
Resolved! :o

Apparently it was due to the fact that I installed Xposed Framework that causes the update process to fail.

I try to manually update the OTA.zip via stock recovery and found out that the process stopped at

Further checks showed that Xposed replaced the app_process file and causes it to fail checksum. I then copied /system/bin/app_process.orig back to /system/bin/app_process.

After that, the update was a breeze. The recovery used was from 3.15.707.4 (extracted from OTA.zip).

I've also S-OFF and Super-CID during my testing process.

If your update process stops after 25%, usually some checksum error has happened. Use manual update to determine the error message.

I'm having a problem updating my Butterfly to Android 4.3 from 4.2.2

My current firmware is 2.33.707.3 and the upgrade version is 3.15.707.4.

On my current phone, I have unlock my bootloader, flash recovery to TWRP 2.6.3.0 as well as rooted it. Due to inexperience, I did not backup my original recovery.

As per gleamed from this forum, I've tried to flash recovery from other stock ROM to proceed with the OTA update.

Steps taken:

Clicked Install now on the OTA message

Phone reboots to recovery

Phone icon with Green exclamation mark appears

Bottom part blue progress bar appears

Upon 30 to 40% progress, the screen changes to Red exclamation mark and update is stopped.

Edit: Did a Factory reset, problem remains.

I've tried the following recovery from other stock ROM without success.

Recovery from 3.15.707.4 (extracted OTA zip in phone's Download folder)

Recovery from 1.19.707.1 (extracted from DLXB1_U_JB_45_hTC_Asia_WWE_1.19.707.1_V0.0)

Recovery from 2.28.709.2 (extracted from OTA_DLXB1_U_JB_50_S_hTC_Asia_TW_2.28.709.2-1.18.709.3)

Recovery from 1.12.707.1

Recovery from 2.33 (from [MENTION=5050528]Bassie39[/MENTION]'s OTA collection)

Recovery from 2.28.709.3

I've searched high and low for stock Recovery from 2.33.707.3 but unable to locate it.

Any tips or suggestion apart from S-OFF and update firmware, PL99img.zip update via bootloader, look in the OTA collection?
