Step 1
flash an eng hboot (0.98.2000)

To flash the ENG HBoot you can use one of these methods;
1) Fastboot
-Place the .img file (extracted from PG88IMG(ENG 0.98.2000).zip) in C:\android-tools
-Boot phone into fastboot
-Run command "fastboot flash hboot engHBOOToverARX.img" in CMD
2) Android Flasher
-Download from here
-Select phone, select Hboot .img (bootloader)
-Boot phone into fastboot and select FLASH
3) Updater file (PG88IMG.zip)
-Rename PG88IMG(ENG 0.98.2000).zip to PG88IMG.zip EXACTLY
-Place file on your SD card root, and boot into HBoot, and follow onscreen instructions

Spoiler

4) adb shell (LAST LAST resort, one typo and you can brick your phone, do some reserch before doing it
-Place the hboot on your SD card and remane it to "hboot.img"
-Boot into recovery
-adb devices - Must show your serial
-adb shell
-su (it should show #, that means you have the right permission, if it shows $ afterwards you dont have permission)
dd if=/dev/block/mmcblk0p18 of=/sdcard/backup.img (backup your current hboot)
dd if=/sdcard/hboot.img of=/dev/block/mmcblk0p18 (flashes new hboot)

Step 2
flash stock hboot 0.98.0002 (Should work since everything is stock except the hboot)

or
Install RUU 1.47.401.4 again (Should also work, but it maybe say you are trying to downgrade)

or
install a 2.3.5 RUU and avoid the ota.
