If you look at total views in Gsm dev thread there must be a lot of lurkers waiting for s-off etc. A lot of Evo 3ds out there on other Hboots that Revolutionary doesnt support.
[HTC EVO 3D] stonyhawk:
best thing has to be the cpu and the 3d

worst things are speakervolume and i also hate how hard it is to get your battery out

I'm just following with interest now the Evos threads and think you are right. Everything works fine on the Evo 3d but the Dev future for Gsm looks grim.

Coming from an EVO 4G:

Best thing - extra speed and storage

Worst thing - Hboot 1.5 / no S-OFF & side USB plugin.

Btw, anyone with Hboot 1.5 should seriously check out Flash Image GUI to flash kernels, etc. directly from within Android easily without having to use ADB/command prompt method.

Can I use the telstra elite wireless dongle with the xoom?
[Galaxy S II General] henrychukx:
So, i know alot of us SG2 user are always on the go with tweaking, OC/UC/OV/UC, all for better battery!

And i noticed there are no such threads about this, therefore i decided to start this one , so we could all share our experience and UV values for comparison.

I'm on CM7 stable? (2.3.7) with the following UV values set on boot for a couple of days now；

1200Mhz - 1175mV

1000Mhz - 1075mV

800Mhz - 975mV

500Mhz - 875mV

200Mhz - 625mV (yes! i know :p. tried 650mV and my screen washed out!)

like i said, i have been using this for a couple of days now, and everything seems fine; quadrant, Asphalt, golf, maps, everything.

So, what are your values.
[Galaxy S II General] buxz777:
everyones values will be diferent mate mine wont undervolt by much before it crashes , where as my old sgs2 could be undervolted loads

to be honest iam using speedmod kernel at the minute and there really isnt any need to undervolt or overclock

iam getting pretty much the same battery i did on my old sgs2 that could be undervolted loads like your one can

iam also getting great scores on benchmark programs
[Galaxy S II General] henrychukx:
Yes, i know everyone's value will be different, i just think it would be interesting to see what people are doing with their beasts!:D

oh, and what happened to your old SG2?
[Galaxy S II General] yakyllan:
What do I need to undervolt my SG2? Another different kernel?

I am on stock KI3 + CF-Root

Any recommended STABLE kernel?

Thank you
[Galaxy S II General] gusoldier:
From what I've read on xda, you can't go 625.. that's why you can set 650 but can't do that for 625. It will jump to the minimum possible mV. Correct me if I'm wrong.
[Galaxy S II General] rocky23:
I don kno abt this uv thing worked the same on my sgs1 so iam not into uv on sgs2....kernel fixs tht prblm....but will try now an c wat the effect is...presently on siyah 2 kernel.....cheeerz
[Galaxy S II General] :
the minimum that i would undervolt at is at 800mv on 100mhz..anything under that would just freeze my phone...so to the OP you must have one damn beastly phone to be able to go that low..anyway i always manage to get 5hours screen on time with my settings so im happy..but please share how you manage to use it that low and not have any problems
[Galaxy S II General] runnin_miles:
I'm on CheckRom Revolution 1.0 and running RAGEmod U1-v1.1b.

These are my stable UV settings.

1200Mhz - 1150mV

1000Mhz - 1050mV

800Mhz - 950mV

500Mhz - 850mV

200Mhz - 825mV
[Galaxy S II General] henrychukx:
i think each SG2's chip is different in some way.

for e.g, i can't set my 1200Mhz @ 1150mV, would be fine for a min or 2, then freeze. i think i also know some guy on XDA here who has 650mv or so.

what apps are you guys using ? setcpu or tegrak ?
[Galaxy S II General] henrychukx:
I don't think CF-root supports OC/UV. you need to flash a kernel that supports that! its amazing how much battery u can save....

i get about 68-75% left after using the for 14hours! wih about 2-3hrs of music, few calls, sms, mobile internet.

last night i forgot to plug in for recharge and i only lost 1% battery in 8hrs!:D:D

its awesome!
[Galaxy S II General] yakyllan:
What kernel are you using for the UV?

Any recommended ?

(I don't want to lose my root)
[Galaxy S II General] viva.fidel:
I'm using roughly similar settings (top is 1252mhz @ 1175mv).. although my 200mhz is at 825mV, can it really go down to 625mV without issues? Anyone else have input on this?
[Galaxy S II General] henrychukx:
now im on CM7, using codewokx kernel (cmw 5.0).

a while back when i was on stock ROMs i used, Ninpho and siyah kernels, both were good on battery, i know with siyah 1.7.8 u can UC to 100Mhz (the standard 200mhz).

u should try one of em out, and see which is best for you.;)
[Galaxy S II General] henrychukx:
On 200mhz, i can only set voltage from 875-800, and anything btw 800 and 625 gives me a reboot. right now im doing 1d3h28m and still got 34% left.
[Galaxy S II General] Geumbou:
Thanks to the OP, didn't think I could get to 625mv on 200hz.

850 mv 200 Mhz was my previous setting (825mv would crash)

Tested 625mv and so far so good. CM7 kernel & SetCPU.

200 Mhz - 625 mV

500 Mhz - 850 mV

800 Mhz - 950 mV

1000 Mhz - 1050 mV

1200 Mhz - 1150 mV

Stable.
[Galaxy S II General] lambstone:
That's unbelievable. my phone just freezes at such a low voltage :(
[Galaxy S II General] leninmon:
Most custom kernels now a days comes with undervolting underclocking scripts.

Eg: my galaxy s2 is on Touch X xwki8 based rom, which contains undervolting scripts.

Mhz : mv

1400 : 1275

1200 : 1175

1000 : 1075

800 : 975

500 : 875

200 : 850

100 : 825

All of them installing these roms never complained on hanging or not booting problems.

I installed them and never caused a problem for me either. But when I replaced the siyah 1.8 kernel with siyah 2.1, the same scripts never worked on the same phone. In fact it never booted. I had to change the voltages slightly inorder to make it boot again.

My conclusion is the phone manufacturers are making the phones almost 99.99%	alike. The changes in volts must be because of different roms or probably kernels installed on different phones. I believe 2 same phones with the same rom and kernel will work with the same under volt script.

What do you think..?

[Galaxy S II General] bervin:
Thanks for the quick reply mate! I'm current on touch power but thinking of switching back to androidmeda could you upload your surgeon for me please? I wanna try it!
[Galaxy S II General] henrychukx:
you'ee prolly right about phones being 99.99% alike, but that 0.01% diff is what determines how high/low you can tweak your phone.

i tried uv my wife's sg2 to 625mv then ofc i got a lockup, had to pull batt and restart
[Galaxy S II General] :
i cant mate upload it for you i am sorry...its for my own to use and i only done it yesterday so still testing it..plus i ported a theme over to use for myself...i have permission if i want to release it but again thats another story...apologies...

but it does not matter what surgeon you are on any surgeon you use with the right settings on setcpu you will get good results..:D
[Galaxy S II General] leninmon:
The 625mv you setup on ur wifes phone may work with a different kernel or rom. Thts my point.. ;)

Did anyone here using the same low voltage specs on 2 different galaxy s2, with exactly the same rom and kernel faced any problem...? I've used it and faced no probs. Tats y I'm asking..

Anyone....?
[Galaxy S II General] henrychukx:
No. i just flashed CM7 on it. still got a reboot when set to 625mhz...

i'm guessing when phone's ain't from the same mother :D:D
[Galaxy S II General] viva.fidel:
Well in a follow up to my prev Q on whether 625mV was feasible.. Tegrak app only lets me UV to 750mV anyway, at which point it hangs after a few seconds, seems stable at 775mV, guess my SoC isn't as bulletproof as some of yours!
[Galaxy S II General] AndreiLux:
Setting anything under 650mV is not possible because the voltage regulator has a hard-coded limit of 650mV, that's why if you actually set it to 650 your phone will crash, any thing below and it will default back to the default voltage. No phone will run under 775mV.

Similarly, lol@ the guy with 830mV and other non-25mV step voltages, the regulator also doesn't support anything finer than 25mV steps and if you set it to something else it will also default to the stock voltages.
[Galaxy S II General] ewokuk:
i was wondering about undervolting mine to get some extra life out of it (if i can run the same speeds at lower voltage then that can only be a good thing), but thinking about it, the vast majority of the power is used by the screen right? so undervolting the cpu is probably not going to make a great deal of difference to the battery life surely?

What will seemingly make the difference is the modem, the kernel and the screen, FAR more than undervolting? of course im very new to it so it might be far more worth it than i am thinking. does anyone have any stats on how much power you might save with an 'averagely' undervolted s2? (average rather than an unusually good one thats had lower voltages than most people will get).
[Galaxy S II General] henrychukx:
What ya mean anything under 650 is not possible ? my phone's running at 625mV for almost a week now, i'll try to post a screenshot in a bit. i did 1d9h43m on my last charge. with moderate wifi, sms, calls, music and mobile internet.

Here are my screenshots. at 2hr 36min i still had 100%, now at 4hrs i still got 100%, with 2 calls, camera, wifi for 10mins and 1 sms...

And if yes ...

I have tried to go lower, but keep it just keeps freezing or rebooting the moment i press 'apply'.

Is there anything I can do to go lower, or is every phone a bit individual when it comes to what they can handle?

That's why posting values is actually a bad thing.. ppl copy it without knowing this..

[Galaxy S II General] leogeeko:
I think you didn´t understand what he is trying to teach you. Our phones have a hardware lock that in case you go bellow 650 mv it will run at the stock voltage (850 i think?). That´s the reason 650 mv freezes and 625 does not, 650 is accepted by the controller.
[Galaxy S II General] andevin:
I see. What are we undervolting, really? Is it the battery, so that I can get other values if I get the 2000 mAh one, or is it the CPU itself?
[Galaxy S II General] Pfeffernuss:
Your screen was constantly on for two and a half hours which resulted in a ZERO percent battery drop.

You have the best friggin' phone in the whole wide world, congratulations! :D
[Galaxy S II General] henrychukx:
Actually, there's nothing wrong with posting UV values. nothing would go wrong, your phone only reboot, or freeze (just make sure you don't thick the "set on boot" option until you're sure the values you set are stable.

;)

And for those guys who keep blabbing that the phone won't go below 650. THAT A PURE LIE. i made and experiment to see if my phone's actually UV'ed to 625 or "default" (whatever that means!).. i set 200Mhz @ 625, 775, and 800mVs. and with phone on standby (screen off and music playing) i can go more than 2hrs before losing 1%; at 775 it was different. @ 800mV my phone lost about 3 % in just 30mins!. The fact that your phone can't run below 650 doesn't mean others can't.
[Galaxy S II General] s2d4:
lol... ummm.. so the regulator limit is bypassed by software? is anybody home??
[Galaxy S II General] Freakgs:
You just made my day, mate.
[Galaxy S II General] henrychukx:
Lol.

My guess is that it has to do with kernels. some kernels have UV cap at 600mV while so have them at other values. i switched to siyah 2.1 and the UV cap is 750! anything below that will "default" back to 750mV.... i'm guessing that's what you mean by the "default" voltage...

I have experimented on this using both my sg2 and my wife's. the lowest UV varies between them.

My father in law bought a new phone SGS on O2 and I offered to unlock it as I have unlocked my husbands last week (he's was on O2 as well but in 2.1 or 2.2.1 version I think-froyo?)

Before I continue may I say I know you guys out there know so much more than me and I really need your help. I really tried to help unlocking this phone and for hours I searched and read things like reboot, download mode, recovery mode, flashing, JKV and so many other words and letter that I could not understand. Very few I understood in the end but may have messed up badly (?).

Please, I need help and please treat me as if I were your mum or even grandma. Step by step in simple normal English please.

My father in law's version is 2.3.3

I tried unlocking it the way I unlocked my husband's but didn't work. After looking for hours I thought that the best way to do it would be to downgrade from 2.3.3 (gingerbread (?)) to 2.2.1 (froyo (?)) and then unlock it.

I found this:

http://xdaforums.com/showthread.php?t=1089989

and tried to follow it.

I downloaded EZRom and EZboot-Froyo-1.0.tar.md5 from the same post.

I followed:

•Download the right version from section above

•Reboot your phone into Download mode

•Connect your phone to computer

•Run EZOdin

•Select EZboot-Froyo-1.0.tar.md5 or EZboot-GingerBread-1.0.tar.md5as a PDA file in EZOdin

•Check the "Phone Bootloader Update" checkbox

•Click Start

I waited for the phone to turn off and feel the little vibration but didn't. Instead it just froze at the first screen when you turn on the phone. The black background with white letters: Samsung Galaxy...

I waited and waited and as nothing was happening I then I took the battery out. Put it back in and tried turning it on. I wouldn't it would just stop and that same screen, the black and white one.

I reread

•Wait until phone reboots and make it reboot into Recovery

SO then I remembered in the many threads I read about the recovery mode so 3 clicked vol up + button at them bottom and turn on bottom.

It gives me a few options. When I click on reboot all it does is show me the black and white screen again and nothing else. ah!!!

I took the battery off and put it back on many times, I also selected the fatory reset option and tried different buttons but nothing. Please help me.

I'm happy to phone any of you guys to help me and guide me even if it's just to put the phone back to what it was before, turning on normally, etc. I'm feeling really sad and a bit stressed as these days are supposed to be a nice time to spend with my little ones and family.

Anyway, please ask me anything.

Thank you so much in advance. I really hope I didn't do anything wrong and I'm just stuck because I'm ignorant in this matter. Thank you

I was never a fan of EZ-stuff.

That said, think you can easily solve that flashing your phone with odin and a proper rom. At this point i am unclear about what bootloaders you have on your phone since you've tried a downgrade.

Without getting into further details (sorry, at work atm). You can get tutorials easy for all of this around this forum.

I'd get Odin, get a proper stock rom from samfirmware with bootloaders included and flash it fresh from start with that. Doesn't really matter if it's froyo or ginger as long as it includes bootloaders.

You'll be left with a working phone at this point.

From here, if you still want to try to unlock it, i'd flash a kernell that would get me root (like the ChainFire one) since i find this the safest and easiest way of getting root on your phone and do a backup of your EFS partition (preferably saved in your computer or wherever outside your phone). This is very important, if you lose of mess up with this part of your phone it will be a pain.

Now, there are several ways of unlocking this phone, the only one i found to be most reliable (but not the easiest one) is to manually edit the nv_data.bin file (located in your EFS partition in hexadecimal.

There's a tut right here

Thank you so much for taking the time to reply although you are working!!! Really appreciate it.

I'll try your suggestion but I don't know how to choose the right stock rom with bootloader from samfirmware. I went to the website and registered but don't really know what to do.

I know you are working so might not be able to help me, may be someone else?

Here's where I am. Update. I found a list of firmware. This is the last one on Samfirmware.com.

Things I need: (I think)

-Download a firmware (should I use the lastest one?) or 2.2 or 2.3.3? . Is there one better than the other? or is it my choice? How can I choose the best one for me?

-Odin. I have OdinMultiDownloader v4.03 in my desktop. Is that the best thing to use or should I use Ezodin. I don't know what the difference is.

-(Do I need to download or do anything else?)

Things I should do:

-Put phone in download mode

-Plug it to the laptop

-Open Odin (or Exodin?)

-click PDA. Choose the fie I downloaded-firmware.

(-after this I don't know what else I should do or tick or untick)

Am I in the right track or completely off it?
