Please read the previous posts.. A lot of ppl had this problem and had to gain s-off fr the ROM to work properly.

---------- Post added at 06:45 AM ---------- Previous post was at 06:41 AM ----------

I was s-on and had the same problem. Gained s-off even thou I never wanted to do it.. I also found that the latest cwm touch worked better fr me while flashing the ROM.. When I flashed thru twrp the phone would just restart while the ROM was flashing
[One (M7) Android Development] ronni.rasmussen:
I suggest you read a bit or search through the topic. There is countless posts about the random bootloop.

Anyway, it worked for me by getting s-off and cid 11111111.
[One (M7) Android Development] phantomzer0:
I go through all the apps I have once I install them and turn off any background analytics for starters. Its ****ty but whatever. Apps like reddit sync want to push private messages so I disable those options.I don't care for instant updates on facebook or any of the other various social apps so I shut all that auto update **** off. I have no issue manually refreshing these kinds of apps. Then I set weather apps to refresh every 4 hours. If I can't set the frequency I uninstall. I used wake lock detector all the time on 4.3 so I was able to figure out which apps I could configure to stop sucking all the juice. I keep brightness at 100% so you could get better battery lowering it. My signal strength was highoat of the day too, which factors in huge. I don't play games on my phone either.

All Google services sync normally. I'd probably get better battery disabling vibration and touch sounds but I'm not that hard up for juice.

[One (M7) Android Development] Billyrouth:
What rom are you guys using to gain s-off?
[One (M7) Android Development] d_phekt:
I used an official CM10.1.3 rom and gained S-Off with Rumrunner
[One (M7) Android Development] skymera:
Very nice.

Scroll bar does seem laggy. It did on CM11 roms too but never thought it would on GPe?
[One (M7) Android Development] baedaa:
what scrollbar?
[One (M7) Android Development] skymera:
Notification pulldown, bad choice of wording.
[One (M7) Android Development] baedaa:
you're right. I didn't notice that till I watched more closely. but that's so minimal that it doesn't really bother me. opening quicksettings on sensebased ROMs is much more laggy
[One (M7) Android Development] skymera:
In fact the notification bar is extremely laggy when I have a WhatsApp notification

---------- Post added at 12:53 PM ---------- Previous post was at 12:52 PM ----------

Only noticeable when you have a notification.
[One (M7) Android Development] baedaa:
tried again, took some time till someone wrote me on on whatsapp (piece of sh.. app, not even ART compatible). the notification pulldown was exactly as it was without a notification. also had open notifications from gmail and tapatalk. all in all I would say it appears fluent
[One (M7) Android Development] pigr8:
it's laggy when you have the phone in standby with screenoff and you receive a notification, if you press Power to screenon and slide down it will lag as hell, maybe cpu ramp-up dunno.

if the phone is in screenon usage and you receive a notification or text all will be fine.

---------- Post added at 01:52 PM ---------- Previous post was at 01:45 PM ----------

M7_UL, S-OFF, and SuperCid and I can't get this to run.

My phone is the ATT version, if that helps anyone.

Wiped everything but internal storage, go to install, and it reboots after about 30 seconds and boot loops..

Have tried reinstalling multiple times to get it running.

Ideas?
[One (M7) Android Development] designerfx:
I have the same issue with the same phone. Not sure what the deal is, I've tried wiping cache/dalvik/factory and reflashed and I still have the same problem of a bootloop as well.

[One (M7) Android Development] devilwarier9:
Disregard me please
[One (M7) Android Development] soopermarkus:
This happened to me on an older version of TWRP recovery. Upgraded to 2.6.3.3 and had no issues with flashing.

AT&T phone

super CID

S-off

TWRP 2.6.3.3.

hboot 1.55

My only issue is my iBolt XProDock car adapter isn't recognized at all as a car dock. Otherwise this is definitely DD material.
[One (M7) Android Development] tpayne1:
Yeah...twrp 2.6.3.3

Edit: hboot is 1.44.....could this be the issue?
[One (M7) Android Development] BuffMcBigHuge:
Got this working on the first shot.

CWM 6.0.4.5

Hboot 1.55

CID 1111111

S Off

Its running fantastic, and with gravity box, it becomes my new ROM of choice. Oh, and it boots in literally 4 seconds from a reboot in recovery. Amazing!
[One (M7) Android Development] rooster_yang:
Just flash this rom with twrp , everything is great , anybody have working aosp browser apk can share thanks
[One (M7) Android Development] kalapyu:
Hi there,

Just flashed the fantastic rom. And it seems to be working perfectly.

Got a noob question though: where is busybox?

I though this app was preinstalled in this package - and i don't see it.

I installed the app version from the play store - still did not figure out how to remove the 3 dot legacy menu, change the tile menu, and activate the advance reboot menu (yeah, I feel like a looser ;))

In other words, why is this rom better than the GPE RUU?!?!?

Thanks!!

[One (M7) Android Development] vud911:
Thank you for fixing my issue. :highfive: To everyone who needs the easiest way to S-Off, the above link is it, from there run Rum and then flash Kit Kat.
[One (M7) Android Development] IlyaKol:
So, what I really should do is:

1) Backup current 4.3 GPE ROM

2) Install latest TWRP

3) Flash the stock rooted ROM mentioned above

4) Run RumRunner and achieve S-OFF

5) Put 4.3 GPE ROM back on phone

6) Update to 4.4 ROM?

This way, all of my home screens, app settings, etc. are still intact and present? If I go directly from Stock Rooter to 4.4 GPE, won't I need to reset everything up?
[One (M7) Android Development] Hussainally:
Can I just flash the radio attached at the op via cwm?
[One (M7) Android Development] xtremedrunk:
I've installed the rom but every now and then I'll get a message saying I inserted a sim and to reboot when I've just been using the same one with no changes. I can usually just keep clearing it to bypass it but it gets annoying. Anyone else have the same issue? I flashed the radio too. Thanks in advance.

installed 4.4 KRT16S incl. newest firmware on my HTC m7_ul :)

(S-Off, CID-11111111, hboot 1.54)

enabled ART (incl. whatsapp-fix)

NEVER GOT A ROM FAST&SMOOTH LIKE THAT

I'm so impressed

AWESOME GUYS

by the way:

I had to fight really hard, until i got this work. Some of my Problem:

1. Windows 8.1 64bit = Some weird driver issues with ADB

2. Windows 8.1 64bit Intel 4th Gen = some weird driver issues with fastboot & USB drivers from Microsoft

3. Android 4.3 & hboot 1.44 = rumrunner didn't work --> revone didn't work

4. installed 4.2.2 Roms instead = revone still didn't work

5. Installed newest radio (from 4.4)

5a. reinstalled 4.3 Rom = rumrunner suddenly worked

6. installed KRT16S = whatsapp didn't install on ART and dalvik, either.

7. tried some other 4.4 Roms = ART didn't worked in every other Rom

8. flashed newest Firmware (from 4.4)

9. flashed KRT16S again = FINALLY it works incl. ART & whatsapp

I don't know why some of my issues appeared. I am just happy that it works now :)

What's the problem? Maybe CWR?

[One (M7) Android Development] BuffMcBigHuge:
I would recommend using CWM 6.0.4.5. There are too many problems with I hear of with the TWRP on the HTC ONE.

I suggest:

1) Copy 4.4 GPE & CWM 6.0.4.5 to SDCARD

2) Titanium Backup your user apps (optional)

3) Flash CWM 6.0.4.5.

4) Make a nandroid in CWM (just in case)

5) S-OFF and SuperCID using REVONE

6) Wipe Data/Factory Reset

7) Flash 4.4 GPE

8) Reboot and start fresh!

9) Install Titanium Backup and restore user apps (optional)
[One (M7) Android Development] shreeram:
Use TWRP

Even i had the same problem. Some_metadata_changes:Failed.Installation Aborted.. Status 7.. CWM is the prob

Use TWRP recovery to flash:)

---------- Post added at 10:22 AM ---------- Previous post was at 10:20 AM ----------

I never had single prob using CWM in HTC1 but for the first time, I had problems flashing this ROM with CWM. But to my surprise, it installed smoothly using TWRP.
[One (M7) Android Development] IlyaKol:
Okay looks like I had the right idea. I'm not going to use Revone since I wasn't able to use it before. I flash to an old stock rooted ROM for S-OFF and do RumRunner.

Thanks!
[One (M7) Android Development] roblxskye:
Will this work for att HTC one?
[One (M7) Android Development] mito8485:
Yes it will
[One (M7) Android Development] Helsie:
Maybe nice to know for some people who have HTC One M7UL with HBOOT 1.55 who need to obtain S OFF:

(Note: follow all additional steps that are associated with each action that I describe!!)

- I received a new HTC One under warranty with this damn new HBOOT.

- I ran into issues when flashing this ROM (bootlooping, 5 secs after boot up)

- I flashed CM 10.2 latest nightly without Gapps (from http://www.cmxlog.com/10.2/m7ul/ )

- I had to apply SuperSU zip update myself to get a superuser binary.

- Grant root access to ADB in developer settings

- Downloaded latest generic Rumrunner HTC 0.5.0 from http://rumrunner.us/downloads-2/

- I had to run it at least 5 times until it went through properly (!!!!). Note closely that ADB will ask for Root permissions. Keep on observing if it does it again, otherwise Rumrunner will fail.

- Enjoy the funny shell messages on your command prompt.

- And then it worked, finally.

Thanks everybody for the usefull resources in this topic!

(I know I provide steps that shouldn't really matter for the solution specifically, but I want to be as clear as possible for others who have these problems).
[One (M7) Android Development] IlyaKol:
Like I said...Revone does NOT work on my phone. Just tried it again.

I opened an ADB shell, did the following commands only to get Revone: Permission Denied

cd *blah*

chmod 755 revone (also tried chmod root:root revone)

./revone -P

And then got permission denied.

This is the same crap that was happening to me a few months ago trying to use Revone.

Still messing with it...going to go the RumRunner route most likely.

Need to S-OFF

Hi,

I'm running bigxie_m7_GPe_JWR66V_odexed-signed on my HTC One with hboot 1.54, S-ON, CID VODAP110 and ModelID PN0710000 (SwissCom).

I'm searching for S-OFF utility and found Moonshine.io but I understand that Moonshine will only works with stock roms ond known rom versions.

Is “universal” version of rumrunner the right and secure choice to get S-OFF?

I had the same problem. I resolved it by flashing to stock rom (I used the HTC ONE all in one tool 2.0 to push the rom to my sd card) and then using rumrunner htc 0.5.0 to go to S-OFF .. then i just flashed normally.
