I would say yes, i Always start fresh when there's a new base involved. Or when the first digit of the rom change like v11 to v12. However others go for dirty flashing and report no issues.

[One (M8) Android Development] jonwilliams84:
Hi...I have just tried 20.1 from stock following the guide on the OP without realizing that I would need to update the firmware...for obvious reasons on 1st boot the Wi-Fi will not work. So, I have restored my nandriod back up for now but would still like to make the move to ARHD 20.1. I am a bit confused as to whether my phone is ok to flash the new firmware:

I have CID H3G_001 with firmware version 2.22.771.5 and am currently S-ON and realize to update I will need to re-lock my bootloader but will it be safe considering I cannot find any mention of my current software version supporting the update to v3.28.xx?

Any help would be awesome, I have been an avid ARHD flash-a-holic since the Desire HD days, so really want to get a taste of the latest ARHD action!!!

Cheers

I think you need to do a bit of reading in this thread and others before you go messing around with firmwares. Not being condescending, but you sound like you're underage. Please read the threads relevent to flashing firmware, s-off etc, especially this thread: http://xdaforums.com/htc-one-m8/general/vomerguides-m8-bootldr-unlock-s-off-t2800727

[One (M8) Android Development] nysoprano:
Thanks ilithia! But,

In the last firmware update, i replaced the radio.img with the one from the T-mobile firmware so i wouldn't have problems with LTE and deleted the recovery.img so it wouldn't erase TWRP. Vomer's guide, the link you posted, doesn't explain this. I have forgotten if boot.img affects s-off, which is why i asked in the forum, along with my other two questions to confirm.

I think you're the one who needs to do some reading OUTSIDE of this thread and get more knowledgeable on HTC phones. And if you have nothing to add, which you didn't, please do not waste a second on my post, it's above your comprehension.

P.S. If your variant hasn't received a firmware update yet, and the WWE firmware isn't compatible, then you're just going to have to wait on flashing 20.1 until it does (unless you don't care about WiFi).

I've had 11.2, after trying to Relock the phone and install the new firmware successfully , the phone couldn't work probably it only can go to the Hboot screen or stay stuck at htc logo. I tried to unlock the phone, go the the recovery and do more but I couldn't. Recovery screen shows just a pic of a phone with a X on it. I did format my phone few times but that doesnt work.

I have the stock 2.22.40 odexed rom if I can use that to help saving my phone through some way? :((
[One (M8) Android Development] DLG187:
You might have to reflash a recovery using fastboot commands.

I did this, using 2.8.0.3 twrp.

Hold power + vol up, till the screen goes black, then hold power + vol down. This should get you to hboot. From here run the fastboot commands to flash recovery.

Reboot.

Hold power + vol up, till the screen goes black, then hold power + vol down.

select recovery on hboot and flash 20.1

Another find:

Also If you head over to the ATT M8 thread for native visual voicemail for indepth guidance the att 4.4.2 visualvoicemail, phone, htccontacts, htcdialer, messaging apks to /system/priv-app (be sure to set permissions for system level rw-r--r--) allow the files to overwrite the delete the 4.4.4 htccontactsdialer.apk and then edit the default.xml in /system/customize/ACC for region 1 and SKU 7 it will work. Does not work on wifi that's app limitation and when setting up Wi-Fi must be OFF and the registration does take a few minutes longer youll get a message saying confirmation hasn't completed or something to that affect but in a few minutes itll ask you for your voicemail passcode.

You need to update firmware as a separate procedure and then flash ROM. If you are s-off this can be easily done following the guides.

If you are s-on, you need to get back to stock and wait for the OTA from HTC to upgrade your firmware and then be able to flash ARHD 20.1

[One (M8) Android Development] Mischa42:
Hi,

you need to be S-OFF to flash firmware. See VomerGuides with more details on how to flash. To get S-OFF you can try some free option or to pay about 25$ for Sunshine solution. I had to pay, as other options did not work my M8.

It is not recommended to install ARHD without related firmware. See Announcement from mike1986 at beginning of this thread.

All the best!

Please could someone clear up what I need to do now? I have read through umpteen threads and cannot find anything out on how to progress with my handset.

My CID is H3G__001, my MID is 0P6B10000 and firmware version is 2.22.771.5 (Three UK)

I have unlocked via HTC-Dev and currently have stock ROM as after flashing 20.1 I had no wifi so realized that I need the 3.28.401.6 firmware (so restored the nandroid backup I made before flashing recovery, but for some reason still have custom recovery), but I cannot get my head around how to go about getting 3.28.401.6 firmware onto my handset (or if it is even possible :confused:)

I have looked into S-OFF but found a thread from another member with same CID and MID saying that firewater doesn't work. So was thinking to relock my bootloader, download the 3.28.401.6 firmware, add my CID to the android-info file and then flash. (but not sure if I need to be S-OFF, or if this would even work???)

Help, please!!!!
[One (M8) Android Development] Mischa42:
If Firewater does not work (as for me), there is currently only one way to get S-OFF (as far as I know). You need Sunshine but this will cost about 25$. It worked fine for me. If you do not want to S-OFF your dive (or can not) you will not be able to flash latest firmware. If you do not have the lasted firmware you can not install ARHD (you can but it is not recommended).
[One (M8) Android Development] benj!:
I was also H3G__001 and got S-OFF via the Sunshine method (Firewater did indeed fail). Sunshine worked like a charm, though.

Then just changed the CID to 11111111 and follow one of the firmware flashing guides - it's pretty straightforward :)
[One (M8) Android Development] Mischa42:
Yepp. Same for me.

[One (M8) Android Development] benj!:
I don't think you do, no. I was, but only because I didn't read the instructions :P

When I originally installed ARHD it was over the H3G firmware and took about 15 minutes to boot every time. Apparently I should have reflashed a stock ROM before running Sunshine, but just ran it from ARHD and it still worked (phew!)

Also, the Sunshine app will run some tests and tell you if it can continue before you pay, so no don't have to worry about getting to that point if it's not going to work
