[G3 Q&A, Help & Troubleshooting] Amb669:
i had to return my first G3 for a new one because the glass wasn't properly attached but before i returned it i noticed my device was warm and it had a 2-3 second delay when i would knock on, didn't really think anything of it at first, thought maby it just took along time for the cpu to fire up.

but after exchanging my G3 for a new one right away i noticed it was quite cool and fast compared to my first one AND the knock on feature on my new device is INSTANT, unlike my first one.

so i conclude my first device had some random issues right out of the box.

i would try a full power down, wait about a minute while it's off so it can static discharge then turn it back on, if that doesn't help maby try a facorty reset and if that doesn't help maby exchange it if you still can.

it's either apps/settings (factory reset to find out) or bad manufacturing like mine was.
[G3 Q&A, Help & Troubleshooting] garcijua:
Thank you, I'll try the factory reset hopefully that works. Otherwise I'll try to exchange

Hi Guys,

I saw this on a foreign website. Not sure if this has been posted already.

[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]

This will turn on power management for the above protocols. Logically, it should save us some power. The orginal poster claims that there is a significant increment in his battery life .

I've applied this tweak to my SPV M3100, Hopefully this will save me more battery life.

N.B. please do a backup before applying this reg tweak just to be on the safe side.

Update: been using it for the few days and I must say I've noticed some improvement in Battery life. no other issues at the moment so far so good
[8525, TyTN, MDA Vario II, JasJam General] fone_fanatic:
What exactly are the above protocols? L2tp1, pptp1... what are those for? its not like that nokia tweak where it gives less power to the antenna?

Basicly is this tweak gonna cripple my device in any way?
[8525, TyTN, MDA Vario II, JasJam General] JohnieWalker007:
The above mentioned protocols are used for VPN (Virtual Prvate Network).
[8525, TyTN, MDA Vario II, JasJam General] software_samurai:
I've made those registry changes to my TyTn. So far, I can find no bad side-effects.
[8525, TyTN, MDA Vario II, JasJam General] shogunmark:
no bad side-effects... but what about good?
[8525, TyTN, MDA Vario II, JasJam General] software_samurai:
Hmmm... Well, so far I think the battery life is a little better. But I need more time to really test it.

(Now that I've installed the Battery Status plugin, I can see the power usage, so I'll fiddle with these settings and see what happens to the numbers.)
[8525, TyTN, MDA Vario II, JasJam General] icemantwilight:
Thanks for posting.. but Like most random registry tweaks, I'd suggest not touching them for the following reasons:

They are not in the associated MSDN documentation for the reg keys. This is usually MS's way of saying 'this doesn't work right so we don't talk about it so no one thinks we support it'.

Second, the protocols it refers to are all network protocols that aren't generally in use by most people anyway and those that do wouldn't have vpn's running 24/7 therefore any power savings would be minimal.

Thirdly, they were purposely disabled for some reason. I assume because there is a problem with them. And my device is unstable enough :)

Just my 0.02c
[8525, TyTN, MDA Vario II, JasJam General] software_samurai:
FYI: My test results

In my admittedly objected tests (I changed those settings, soft-rebooted, and then watched the batter drain number for a few minutes), it looked as though enabling the power management for those 4 settings brought the batter drain down a little faster then with them disabled. When they were disabled, it took several minutes for the battery drain to drop down to about 90mA. When they were enabled, the batter drain dropped down to 90mA within about 2 minutes. However, in both cases, the battery drain seemed to bottom out at about 88mA after a while (actually, right after the backlight went into power-saving mode). So I can't say these settings would save a "significant" about of power. YMMV.
[8525, TyTN, MDA Vario II, JasJam General] sk0t:
If it's not supported, I can understand it. But, I've found with my Wizard, and now my Hermes, that just because it's disabled, doesn't mean it isn't useable. I've found a variety of registry keys that I love tinkering with. That isn't one of them thankfully, but some of the things that they disable there aren't any problems that I've seen, so therefore I add them back in.

A good example is that "Wireless" today plug in. Sure, it really doesn't server a whole lot of purpose, but I like it, so I put it back in.

Much of it is in the eye of the beholder. N00bs probably shouldn't do some of this stuff. Then again, if it weren't for our curiousity, we'd never make any progress hacking these devices...
[8525, TyTN, MDA Vario II, JasJam General] aquasesh:
This wouldnt be the right forum if noone would investigate any kind of improvement (or at least finding out if it does anything, positive or negative)

I we would go for what MS suggests or covers in their docs, we wouldnt flash roms, apply MUIs or anything in that regard.

After all this site is called XDA-Developers and playing around with tools, tweaks and sharing knowledge is what this is about.

So far i cannot see any change in battery life. I will give it a few more test.
[8525, TyTN, MDA Vario II, JasJam General] jasjamming:
if there is a way that we could scale the processor based on the processing requirements, then we will always consume optimal power... something similar to speed-step intel has on PC's.

from what I know for this to be possible, the CPU has to have dynamic voltage scaling, meaning that when the processing load is reduced, the core voltage of the cpu reduces yielding reduced clock frequency. when more isntructions need be executed, the voltage supply to the CPU core will increase, hence increasing clock frequency.

has anyone read the documentation in regards to the architecture of the samsung CPU? if it supports dynamic voltages scaling, and if it is wired up to a dynamic voltage source, then there could be some tweak to enable such a feature.
[8525, TyTN, MDA Vario II, JasJam General] vijay555:
I've had the pleasure of reading the Samsung CPU manual. You should too!

It doesn't support much clock speed scaling - ie you can't easily overclock (and even then, not by anything of signficance). Voltage scaling is possible. Look into Pocket Hack Master.

V
[8525, TyTN, MDA Vario II, JasJam General] jasjamming:
if the core CPU voltage can be scaled, then we instantly have a scaled clock frequency. there is a direct relationship between power dissipation in CMOS semiconductors, clock frequency, supply voltage, capacitance and probability if switching (ie dynamic clocking).

Here is an interesting read for you softeare hackers out there. it is a project ot implement dynamic voltage scaling on pda's for those that have CPU with fine grian dynamic voltage scaling. the work is on linux os on a pda, but the methodology should be the same.

http://www.eecg.toronto.edu/~tamda/csc2228/

Dynamic voltage scaling doesnt imply that we can overclock the device, but instead keep the CPU running at a speed that is ample for the processing that it is doing, ie, dynamic. so if there are no apps runing besides an idle today screen, why keep the CPU at 400MHZ running at its full voltage supply. lets reduce it to an amount that it enought to handle the performance requirements of having an idle today screen BY reducing the supply voltage.

Dynamic voltage scaling is basically an algorith (if the hardwre is there) that can be implemented at the CPU level or OS level to monitor instructions required per second etc, then adjusts the CPU core suply voltage accordingly. So in effect, we can get our devices running from 10MHz (doing nothing and consuming little power - I am sure this is the case 70% of the time) to 400MHZ (running apps, GPS, video streaming etc - and consume more power)

I have a PhD student doing his thesis on dynamic voltage scaling for mobile medical devices and the philosophy is "do (process) only what you have to do (process)"

EDIT: Just looked into pocket hack master, it does some kind of clock scaling, well, I learn new things everyday, this is my first PPC and its overwhelming.
[8525, TyTN, MDA Vario II, JasJam General] jasjamming:
vijay,

what is the model number of the samsung CPU in the hermes? i cant seem ti find it?

EDIT: I found it, Samsung K5D5657ACA-D090, it seems voltage scaling is not supported by pocket hack master, that app supports the samsung ric micr S3C24XX series in which the S3C24A0 has a max clock of 200MHz running of a 1.2V supply
[8525, TyTN, MDA Vario II, JasJam General] shogunmark:
also you may want to be careful with Pocket Hack Master.. some people have reported it completely bricking their device. I had it installed it hours before my phone died, but i dont know if it was the cause due to a high amount of irregular bad blocks that werent there when i got the phone.
[8525, TyTN, MDA Vario II, JasJam General] jasjamming:
I dont trust it, it doesnt support our samsung CPU in terms of voltage scaling and by simply scaling the processor frequency isnt really going to accomplish much of an energy saving in terms of the big picture. by big picture i mean with respect to LCD screen energy consumption, GSM radio and UMTS radios (all of which use separate LNA's for each of the Centre Frequency bands) BT etc....

[Nexus 4 Q&A, Help & Troubleshooting] YFBanana:
I recently fixed an infamous bootloop i had by letting the battery die 100% (yeah I know it is bad), and then it booted. Well i went to flash a new rom and it never rebooted. I then went to flash stock from google. Still a bootloop. tried like 3 roms, still a loop. I then tried the killing my battery thing. Still a loop. Please, i know the phone isn't hard bricked, is there anything else i can do to boot it other than just flashing stock and factory resetting. Thanks.
[Nexus 4 Q&A, Help & Troubleshooting] YFBanana:
Another thing, when i try to flash 4.2.2 the phone doesn't go to the boot logo.

Fastboot flash the factory image. Then boot into the stock recovery and do a factory reset.
[Nexus 4 Q&A, Help & Troubleshooting] YFBanana:
unfortunately that doesn't work, i have tried it many times.
[Nexus 4 Q&A, Help & Troubleshooting] jd1639:
Then you have an issue with your device. What happens if you lock the bootloader and then reboot? Does it stay locked or is it still unlocked?
[Nexus 4 Q&A, Help & Troubleshooting] YFBanana:
It stays locked. I am guessing thats a good thing?
[Nexus 4 Q&A, Help & Troubleshooting] jd1639:
Yep, if it didn't your emmc flash memory would be bad. I'd try re-downloading the factory image and trying again. Are you using the flash-all.bat to flash? You might try flashing all the components separately and see if any of them fail.
[Nexus 4 Q&A, Help & Troubleshooting] DillonFixDroids:
You flashed stock firmware and it didn't work? What did it do when you flashed it?

[Nexus 4 Q&A, Help & Troubleshooting] YFBanana:
None of the flashes failed. I have tried redownloading and i have also checked the md5's, so i dont think that would be it. I have also tried reformatting through twrp, and then flashing stock. Still nothing.
[Nexus 4 Q&A, Help & Troubleshooting] YFBanana:
flashing 4.4.4 separately got me on the starting apps step, but that seems to be the place where it gets stuck.

[Nexus 4 Q&A, Help & Troubleshooting] groovepeppy:
so now you can boot to 4.4.4 ROM but your phone stuck at the "Starting apps" box rite?
[Nexus 4 Q&A, Help & Troubleshooting] YFBanana:
I think it was just the order i flashed the img files that made it go to that point, but i am pretty sure starting apps is where it gets stuck every time.

but i hope you can find the cure soon
[Nexus 4 Q&A, Help & Troubleshooting] acejavelin:
You can obviously get into flashboot, have you tried booting the latest twrp, wiping /system /data /cache and sideloading something different, like Paranoid Android?
[Nexus 4 Q&A, Help & Troubleshooting] sribha:
Bootloop fix

First thing is that you have use Wug's Tool and flash the 4.3 stock image. In the Wug's tool select the option 'SOFT BRICK or BOOTLOOP' option and then flash the stock image in the fastboot mode. Definitely, I hope the phone will launch without any problem. The same problem I had faced with my nexus 4 and I flash the 4.3 stock image with the help of Wug's tool. Try it I hope it will fix the problem.

[Nexus 4 Q&A, Help & Troubleshooting] Cristi02:
What sensors? Can i fix/replace them? I have a odd problem with the proximity sensor, it sometimes works and sometimes doesn't but i don't think this causes the bootloop problems.
[Nexus 4 Q&A, Help & Troubleshooting] YFBanana:
It does cause the problems, just google around, it is answered on many forums. If you could use KK, your phone wouldnt even go to the boot logo for 4.2.2.
[Nexus 4 Q&A, Help & Troubleshooting] Calzoniee:
I have a very similar issue (bootloop) where my phone still shows custom after a factory rom flash. i've tried every recover from softbrick option I could find and nothing. It boots into setup, freezes, and reboots. Even went as far as erase nand because nothing else worked and the same thing happens.

I know at least the 4.3 (what I was on) to 4.4 worked because the kernel shows NC4 in recovery.

Anyway, i think I'm hosed unless anyone has another suggestion.
[Nexus 4 Q&A, Help & Troubleshooting] jd1639:
Try the 4.2.2 factory image. There's been a number of people with bootloop problems where 4.2.2 is the only thing that worked. It's a hardware issue but I don't know what causes it.

OK, not sure I've tried that rom, only retried 4.3 and 4.4. I'll give it a go.

Samsung Note 3 currently loaded with Biggins Rom V7. Cannot update to V8???

I had to read through HUNDREDS OF POSTS to find this.... "V8 misidentified as V7".....Is this true?

I thought I was going CRAZY spending the past 2 days trying to update. However.... I cannot tell the difference of V7 vs V8 which leads me to believe I am STILL on V7? Everything seems to look and act the SAME? I do not see any of the mods like I see in so many other provided in this forum? How do I know what it is? How can I tell the version? Do I need to update with V8.3 to fix?

I have done EVERYTHING step by step stated in the directions. If however a specifc DETAILED step is missing... I do not know? This is my first time and I purchased this phone with V7 already installed. Should I Wipe Factory? Or should I leave Factory alone?

I have done EVERYTHING:

1) Reinstalled Busybox from Playstore

2) Reinstalled Safestratp 3.75 B04 as provided by the link

3) Rebooted into Safestrap. Performed Wipe on Dalvik Cache, Data, Cache.

4) I rebooted into Download Mode and reinstalled the NC2/ NC4 updated kernel firmware using Odin 3.09.

Initially I was trying to flash the V8.3 update directly. I did not realize this was not a full ROM? Did this screw something up??????

What am I missing here?

Neebie.
