No issue here. Root is working fine.
[Sony Xperia Z Ultra] pemell:
Don't know mate. I flashed over stock 757 and everything went fine.
[Sony Xperia Z Ultra] maxld:
Okay, that was weird. SuperSU disappeared from my phone. After reinstalling it from Google Play everything is working. Sorry for a little bit of panic :silly:
[Sony Xperia Z Ultra] pemell:
Glad it works for you too. This new kernel makes my phone crazy smooth and fast. Try intelliactive governor and oc to 2.4. :thumbup:
[Sony Xperia Z Ultra] maxld:
Thanks for the tip, however I am not so sure if this phone needs OC. I would rather like to have a longer battery life.
[Sony Xperia Z Ultra] pemell:
Ok try intelliactive with no oc (or even uc). Anyway, thanks again dbolivar for the port.
[Sony Xperia Z Ultra] maxld:
Yeah, I've done just that, and yes - Dbolivar thanks for the incredible work and bringing this baby to our devices.
[Sony Xperia Z Ultra] shaolin95:
I so much wanted OCing! This is heaven :D :highfive:
[Sony Xperia Z Ultra] pemell:
Yeah me too. With an intelligent governor it won't drain the battery that much more.
[Sony Xperia Z Ultra] shaolin95:
Are you using it for all cores ?

[Sony Xperia Z Ultra] louis0612:
I'm using Monx 681 and Doom kernel v11r2,everything works flawlessly.And after i flash Doom v14,my ZU couldnt boot into start screen.

This kernel only for new rom?
[Sony Xperia Z Ultra] dadme:
v14 not scaling freq. well on stock rooted .757, going back to v.13 deep sleep and all freq are ok.
[Sony Xperia Z Ultra] maxld:
Yeah, at first I had a random reboot and then I got stuck with 300mhz and whole phone lagged as hell. Rolled back to stock .757
[Sony Xperia Z Ultra] bryanky5:
Were you still on Monx 681? because from v12 onwards it won't boot on anything that's not 757

this is from original Z1 thread

"This wont boot on older stock ROM (.681 !!!) or ROMs based on older FW, you will get bootloops!"
[Sony Xperia Z Ultra] pemell:
I've got absolutely no issues at all with v14.

Thanks [MENTION=4972043]dbolivar[/MENTION] for this great port.

OC to 2.4 with intelliactive and row.
[Sony Xperia Z Ultra] skylinestan:
I can't boot into my monx version 757 on v14 too.Is there anything that need to clear before flashing this kernel?On v11r2 is fine for me...

Sent from my C6802 MONXdified ROM
[Sony Xperia Z Ultra] :
I got random reboot once for v14 on stock rom rooted .757

The screen goes haywire (colorful...) and stucked then auto rebooted...I then flashed back to v11r2

Anyone having same experience on v14?
[Sony Xperia Z Ultra] iBuzman:
Me too, all good. (757, deodexed, uc to 19.5, intelliactive, row)

Thx [MENTION=4972043]dbolivar[/MENTION]
[Sony Xperia Z Ultra] bryanky5:
So far I haven't had that but i have to continue using it for a bit longer to truly see if it's stable.

but so far OC'ed to 2.4ghz and no problems whatsoever
[Sony Xperia Z Ultra] theerachai:
V.14 can't oc to 2.4

No problem with V.13

Gov. setting : work fine

try install both from dl link and mirror link, also clear cache and dalvix.
[Sony Xperia Z Ultra] pemell:
What app you use to oc?
[Sony Xperia Z Ultra] bryanky5:
I used setCPU, which is paid i think.
[Sony Xperia Z Ultra] pemell:
Ok! Did you try fauxclock?
[Sony Xperia Z Ultra] iBuzman:
Setcpu paid for me too. :)
[Sony Xperia Z Ultra] pemell:
My only worries would be that the dev behind set cpu is very busy and haven't updated the app for long. That's why I'm searching for an alternative.
[Sony Xperia Z Ultra] iBuzman:
^^ :thumbup: Keep us posted if you find a more contemporary alternative :)
[Sony Xperia Z Ultra] bryanky5:
Nope just looked at it now and it's expensive for me haha $4.81 but anyway we're going a bit off topic now :)
[Sony Xperia Z Ultra] dadme:
Try Trickster mod. Really good cpu control software.
[Sony Xperia Z Ultra] pemell:
Confirmed no overclocking in v14.

cpufreq_limit is set to 2265600
[Sony Xperia Z Ultra] bryanky5:
oh true...oops didn't notice in setCPU i could slide it to 2.4ghz but it doesn't actually change lol...well my bad!
[Sony Xperia Z Ultra] pemell:
Ok I was planning to make a script which enables oc on v14 but tbh it's better to use v13 if you want oc, as the only change in v14 is to cap the cpu freqs. It's very good for people who wants uc, not oc.
[Sony Xperia Z Ultra] :
Over at original kernel thread at Z1 forum, seems like I'm not the only one...
[Sony Xperia Z Ultra] pemell:
No random freezes here.

Ok, if you insist on oc on v14, here is an init.d script.

Create an init.d folder in /system/etc/ and put it there. Set the correct permissions and reboot. OC enabled.

[Sony Xperia Z Ultra] shaolin95:
I have beenn using Pimp My Z1 app. Am I missing something other paid apps offer over this one? I tried Faux but it does not give me the GPU control for example.
[Sony Xperia Z Ultra] pemell:
I'm using my own made init.d scripts. This way there's no need for a separate app.

All apps I've tried so far have some issue, except set cpu. If you read up and create your own script you got total control.

I even have tasker to notify me with a toast when my script executes at boot. It's great.
[Sony Xperia Z Ultra] avetny:
All day walking with max overclocked/smartassv2 v14. (Stock/debloated rom)

Everything is incredible fast. Battery life is superior.

No issues at all. (I using always and only SetCPU)

Here is on v14 without any modifications (Stock/debloated rom)

"0" issues detected.
[Sony Xperia Z Ultra] shaolin95:
I loved this kernel! Still need to find a way to keep the GPU at the max because the max speeds drops down to 450Mhz on its own :/

I am on R13 using the Pimp my Z1 app for it.
[Sony Xperia Z Ultra] pemell:
What is max for the gpu?
[Sony Xperia Z Ultra] shaolin95:
I set it to 533Mhz but then some times it goes back to 450Mhz on its own. Not all the time but it does happen.
[Sony Xperia Z Ultra] pemell:
My sticks. I've edited it manually. You can find a guide in the z1 thread.
[Sony Xperia Z Ultra] shaolin95:
Time to read later tonight. At work now so it is hard to do while helping on 3 chats at a time :/
[Sony Xperia Z Ultra] pemell:
Thoughts after a day of use: amazing!

OC, both cpu and gpu. Not a single freeze and no stuttering whatsoever. Super smooth and extremely fast. Battery life good to, nearly no drain at all when screen is off.

Thanks again [MENTION=4972043]dbolivar[/MENTION]

No idea. As there aren't any other reports about bootloops I guess it's something on your side. Flash stock and try again.

[Sony Xperia Z Ultra] Aphex13:
Please correct me if I am wrong, but I thought zram was a useful thing for devices with lower ram, like 256 or 512. My understanding was that it compressed/zipped parts of the ram that weren't used as much to free up ram for other things that were used more. Then the CPU would have to work harder/use more battery to decompress these items when they were needed again. I don't think we stand to gain much performance on our devices by enabling zram, as we have 2gb of ram. I mean no disrespect, but please tell me if I am missing something.
[Sony Xperia Z Ultra] shaolin95:
Well I always feel that the only way to know for sure is testing. BEncharmk with and without it. Take opening times for apps, webpages etc and see how it turns out.

I always try to give the benefit of the doubt. :good:
[Sony Xperia Z Ultra] ShadowVlican:
http://timos.me/blog/zram-to-enable-or-not-to-enable-229

Great information there from the trickster mod dev

He should know what he's talking about, more so than the rest of us end users anyways
[Sony Xperia Z Ultra] pemell:
It doesn't say anywhere how much cpu the actual compressing uses. I'm curious about this add I have a hunch it don't uses that much at all.

My facts are: when booting device I have 103mb of free ram. Those 103mb could easily be used in a while. Instead of running out of ram wouldn't I benefit from using zram?

I'm not convinced, will try different setups and see where it ends.

At the moment I'm trying 25% of total ram set to zram.

[Sony Xperia Z Ultra] blueether:
We can have it, but it is not perfect and sometime will take 3,4,5... attempts to wake the phone up. We can get it to work every time by having the touch screen more powered, but will drain the battery

a lot

faster. When I have played with higer TS settings I think the battery drain was up at about 2%/h.

DooMLorD has taken it out of the Z1 as well for now
[Sony Xperia Z Ultra] iBuzman:
OT (sry)

I don't understand the obsession with DT2W lol.. Battery worse, screen prone to false taps, and most importantly - replacing one button press with 2 (or more, see prev post) screen presses is hardly more efficient. If any kernel I use implements it (and it's buggy atm) I'll move to another. Thanks all, OT over :)

[Verizon HTC One (M7)] GhostNinja:
Hi:laugh: Well I'm new to theses stuff so I will estate my problem and question:

I bought a unlocked (Verizon) HTC One, and I put my AT&T Sim Card --

The phone recognized the sim and its says 'at&t' and I input the at&t APNs(the 4g because thats its the plan i got)

but I can't call, sms or even going in to the internet its just says E(I think thats means Edge rigth?) and the phone doesn't do anything.

(I live in Puerto Rico)

I had tried in Global Mode and in GSM/UMTS mode.

I cant entered even setting that are suppose to pop when you dial *#*#4636#*#*

The phone is S-On.

What can I do to at least call/txt in the phone? Or what do you guys advise me?
[Verizon HTC One (M7)] Chilidog:
You should be able to text and call fine just no 4g.
[Verizon HTC One (M7)] GhostNinja:
Uhm..

Uhm... I put the 2 AT&T APNs so far(3g and 4g) and neither of them let me txt or call.

I tried a dozen of time now; what do you think the problem is? Am I missig something here?

Update: I got it running, I put another apns that got the call/txt rthings working.

Anyways, mind to tell me why cant I get 4g?
[Verizon HTC One (M7)] Chilidog:
Because the antennas built in the phone are different.
[Verizon HTC One (M7)] dohcvtec:
What about Metro PCS? How does it work there? Anbody can share some experience?

Thanks!
[Verizon HTC One (M7)] GhostNinja:
So...

So what carrier (instead of Verizon) would do the work?

(by that I mean: the phone working with multimedia message, message, 4g, calls)?

In PR we got NET10, CLARO and some other, I just want the phone working with its pros :l

there's no way to patch the radio of the phone or something?
[Verizon HTC One (M7)] Chilidog:
All I know is that everything will work except 4g.
[Verizon HTC One (M7)] dohcvtec:
So it doesn't matter if you unlocked the phone or no, 4g won't work and that's it?

Thanks!
[Verizon HTC One (M7)] Crawshayi:
I have heard that the radios are there but have been disabled. I'm not sure how true that is, but knowing Verizon I wouldn't put it past them to do that so you can't use it 100% on their rivals. Kinda like how every other HTC One has the FM radio but ours is mysteriously broken... hmm...
[Verizon HTC One (M7)] GhostNinja:
Oh

Oh, even it's possible to enable those radios... right now any of the DEVs has been working on something like that?
[Verizon HTC One (M7)] davew41:
What settings did you use?

I have a verizon htc m8 sitting here I put my AT&T nano sim in today I got almost everything working EXCEPT sending pictures as attachments

I can browse the web, I can text, I can make calls, I just can not send a picture in txt messaging??

I did the following

settings

mobile data

cdma options or gsm/umts options

access point names

click the dots

then new apn

[Verizon HTC One (M7)] jpradley:
You're in a forum devoted to the Verizon versions of the HTC One. So why post about your AT&T sim?
[Verizon HTC One (M7)] GhostNinja:
Because the phone is the Verizon version and is unlock that's why about the Att Sim problem.

But its seem that Its not the 'at; like they're saying is suppose to be a problem with the disable radios...

That's why asking is there's a way to enable those radios or something now :p
[Verizon HTC One (M7)] jpradley:
I believe that any radios that do not function in the Verizon version of a phone (including frequency ranges for various cellular services as well as the FM Radio) were not disabled by any sort of software. Instead Verizon supplies phones with modified hardware: the circuitry and connections in the phone. No patch or App can change the hardware.
[Verizon HTC One (M7)] Zachbnonymous:
What about achieving S-Off and enabling the proper radios? I too have a Verizon HTC One with an AT&T SIM. Ive been doing a lot of research into it and found a couple suggesting that method would work. Thoughts?
[Verizon HTC One (M7)] jpradley:
I stand by what I said. A SIM doesn't change the hardware to which it is connected. But: is anyone preventing you from

continuing your research and trying whatever pleases you? I for one will be delighted to hear if and how you got FM to work on a Verizon HTC One.
[Verizon HTC One (M7)] dohcvtec:
So can someone please tell me if Verizon phones are supposed to have G connection only with Verizon sim card, how did my phone had G connection?!!?! :D Where I live and most of the places it says "E" but already I noticed on a couple of places that it says "G". What's the deal? Using MetroPCS!

p.s. Also contacted MetroPCS and they confirmed that I was using "G" connection...

Hello. Same as above, QTEK S200 + Transcend SD 4gb 150X

Everything works perfectly, even quite fast

I only noticed two flaws:

1) the start menu opening, if there are icons linked to programs on the card, is quite slow; just like the today panel had some difficulties reading the huge FAT32 table or structure.

2) photocamera only allows saving to internal memory and network path. Not to SD Storage Card space as before with 1GB SD ...

Any hint ?

Thanks everybody

Valerio
[JAMin, XDA Neo, S200 General] median:
Hi Valerio.

Could you please find out read and write speeds? I would like to know, because I would like to buy that card too.

Do you have more than 2GB of free space on the card? If so, try to fill the card to have less than 2GB of free space and it should be able to save photos to the card.

You can also increase speed by conversion (or format) to FAT16 with larger blocks, but its inefficient for small files because they take more space. Search the forum for details and how to do it.
