Hi guys,

I've just updated my android rev 10.1 to 30.1 but it's stuck in a reboot cycle. Could be because I didn't update the firmware? Still on the older 3.x firmware.

So trying to update firmware - I have the 3.28.401.9 zip in my sdcards root folder but trying to install from zip (TWRP 2.8) it says unable to open zip file, error flashing.
If I try using fastboot flash:

C:\>fastboot flash zip c:\3.28.401.9.zip
sending 'zip' (43011 KB)... OKAY
writing 'zip'... INFOadopting the signature contained in this image...
FAILED (remote: not allowed)

Key bits of information from my fastboot getvar shows something not right:

C:\>fastboot getvar all
INFOversion: 0.5
INFOversion-bootloader: 3.16.0.0000
INFOversion-baseband: 1.16.2133156.UA15G
INFOversion-cpld: None
INFOversion-microp: None
INFOversion-main:
INFOversion-misc: PVT SHIP S-ON
INFOserialno: xxxxxxxx

INFOimei2: Not Support
INFOmeid: 00000000000000
INFOproduct: m8_ul
INFOplatform: hTCBmsm8974
INFOmodelid: 0P6B10000
INFOcidnum: O2___001
INFObattery-status: good
INFObattery-voltage: 0mV
INFOpartition-layout: Generic
INFOsecurity: on
INFObuild-mode: SHIP
INFOboot-mode: FASTBOOT
INFOcommitno-bootloader: ab0efa49
INFOhbootpreupdate: 11
INFOgencheckpt: 0
all: Done!


Whats scary is that it doesn't even show my firmware version?! my phone is unlocked with htcdev - shows "unlocked" and "tampered" so I don't picture s-on is an issue.

Any suggestions on how to unbrick?

You can't flash firmware via recovery!

Search for vomers firmware thread all instructions are there.

You need an 02 firmware. The wwe ones don't work on your phone. And to flash firmwares you need to be in RUU mode.

But look for your official firmware first. Or return the phone to its original stock rom + recovery and update via official ota's

Thanks! So I had tried to flash via RUU mode but it had errored - presumably cause it rejected the ROM file.
My initial firmware update when I updated to rev10.1 from stock android was from vomer's guide. Should I be downloading 4.16.1540.8 without red text?

basically this is what I get if I Try to flash the above in RUU mode:

C:\>fastboot flash zip c:\fw_4.16.1540.8_custom_without_red_text.zip

Go to the general section and look for the stock backup thread. Have a real good read there and return your phone to FULL stock and update via ota.

This one is the latest O2 firmware: https://www.androidfilehost.com/?fid=95784891001603798

You cant install the Lollipop dev edition firmware when you are on the O2 cid. So or het s-off and change it or wait for OTA from O2.

Latest aviable stock backup: https://mega.co.nz/#F!odoimZRD!fXWN36-1i3AUdkAHcgfy_A

yep latest o2 firmware didn't work either :(

I'm going to try reverting back to the old version of android rev that I had and see if my phone gets out the reboot loop. If so I'll probably revisit flashing at some later point when I'm less frustrated, ideally first s-off my phone.
if that still doesn't work I'll probably have to return to stock :(

Maybe your firmware is newer then the link I gave. But with the O2 cid you cant use lollipop with sense. You cant Flash that firmware. So you have to go back on stock.

ah that sucks. ah well.

So to go back on stock, I wan tto use the "Method 2 - flashing RUU (ROM Update Utility)" method. It's not entirely clear on how to do this - do I download the stock recovery 1.54.2016.5 img and folder onto my pc and issue fastboot oem lock command? or does the folder go on the sdcard and the img on my computer? or neither??

Ah man really? What do you dont understand?

If you want to use that RUU to have that developer update to Lollipop you have to change the O2 cid. If you want to change the cid you have to be s-off. Are you not? Use sunshine.

resolved my issue:

- went back to android rev 11.1 (what i was previously using) and wiped device.
- once booted, installed sunshine and went s-off
- updated cid to supercid
- updated firmware to latest 4.x
- updated and wiped into andrdoid rev 30.1

Working like a charm now :)

Thanks everyone for the massive help!

Glad to hear! Hope the $25 for sunshine was worth it
