Leroy,

I think Jakey has it.

I was just about ready to pitch this thing in the trash and I decided to plug in my factory cable one last time and run KFU.

For whatever reason I decided to select the root option again even though it said status offline and it rerooted my device.

My logo is now white/blue and I think I can get a rom back onto it.

You may want to hit Skorpn up for a cable, he shipped it super fast and it's great work.
[Kindle Fire Q&A, Help & Troubleshooting] Copcheck:
Leroy,

Since it seems you are having the same problem I was and replies are pretty slow in here these days (I'm sure most people are tired of repeat posts like mine), I thought I would post precisely what I did to fix mine.

I too had the infinite boot logo that stayed bright and tried everything from KFU, to unbrick tool, to Soupkit, nothing seemed to work. I bought a factory cable from Skorpn, but didn't really understand how to use it. I think there is so much information here and many various ways to get things fixed it takes awhile to digest it.

Right before I got ready to pitch it in the trash I figured I would try KFU one more time even though it wasn't seeing my Kindle. Device manager saw the ADB drivers in Android device though.

I plugged in the factory cable

Launched KFU

Device said "offline"

Tried various options until I finally saw the install permanent root with superuser (option 2)

That did the trick

I then unplugged my factory cable from both the PC and KF and booted the KF into recovery

I downloaded a ROM (Hashcodes and GAPPS) and side loaded them

That did it!

I'm not sure how or why since it said it was offline but it fixed it.

Again, Skorpn was awesome to work with and sent the cable to me quickly.

Good luck to you!

Hi Guys,

I'm a newbie to this site and rooting. I have just flashed my HTC One to Maximus 7 Rom. I'm trying to sign in to HTC and Google accounts but to no avail. HTC says I should try later, which I did a few times and Google is stuck at the signing in stage.

Not sure what to do. Any help would be appreciated.

Hi,

I have started research about overclocking Ace 2.

In GT-I8160 default config there is UX500 use-case governor option enabled.

So we have various CPU configuration functions in usecase_gov.c file such as set_cpufreq or set_cpu_config.

I think that's the point where we should look for overclocking our Aces. Am I right?

Hmm, first I will try to diff GT-I8160 and GT-I9070 kernels, these are very similar phones and one of few differences is CPU frequency.

But now I need mirror for GT-I9070 sources (downloading from Samsung at 15kB/s)

[Galaxy Ace II Q&A, Help & Troubleshooting] ccnky:
Ok, that's what I know at the moment:

-CPU frequency tables in devices-db8500.c file are the same for GT-I8160, GT-I8190 and GT-I9070 with 800MHz max so we can't do nothing here.

-frequency tables are modified by PRCMU driver (/drivers/mfd/db8500-prcmu.c) as we can see in db8500_prcmu_update_freq() function

static void db8500_prcmu_update_freq(void *pdata)
{
freq_table =
(struct cpufreq_frequency_table *)pdata;
if (!db8500_prcmu_has_arm_maxopp())
return;
switch (fw_info.version.project) {
case PRCMU_FW_PROJECT_U8500:
case PRCMU_FW_PROJECT_U9500:
case PRCMU_FW_PROJECT_U8420:
case PRCMU_FW_PROJECT_U8420_SYSCLK:
case PRCMU_FW_PROJECT_A9420:
case PRCMU_FW_PROJECT_U8500_MBL:
freq_table[3].frequency = 1000000;
break;
case PRCMU_FW_PROJECT_U8500_C2:
case PRCMU_FW_PROJECT_U8520:
freq_table[3].frequency = 1150000;
break;
default:
break;
}

}

Unfortunately, db8500_prcmu_has_arm_maxopp() function returns false for our device (it may be caused by hardware) so frequencies are not modified. I'd like to check how is it on GT-I9070 or GT-I8190 but I don't own these devices.

I'm also afraid to manually change frequencies (don't want to brick phone).

Hi, I need some volunteers ;)

http://d-h.st/WGO that's my kernel. ONLY FOR ADVANCED USERS! INCREASES FLASH COUNTER

It don't blow up your phone but GSM is not working, and there's some bug with shell root permission.

I want you to flash it (via Odin), wipe data (so do it only if you have backup!) and try it in benchmark.

Effect won't be so large because of shell bug but I want to try it on more devices.

Here's stock kernel http://d-h.st/vjM

New Kernel Test

I tested the new kernel following this steps:

- I flash JB D8 using odin

- I wipe data and cache

- I install Antutu

- I run Antutu (Test 1 - Screenshot 1 and 2)

- I flash the new kernel using odin - with the new kernel i have 1000 Mhz maximun.

- I run Antutu (Test 2 - Screenshot 3 and 4)

You can see the screenshot .

GSM don't work but wifi seens work.

You have the 1000 Mh posibility but not the 800 Mh posibility like you are changing 800 by 1000 but don't define new CPU steps.

The last screen (screenshot 5) is my actual ROM based in JB D8 (Not public) after come back using restore.

If you want i will do more tests please ask me because i'm very interested in overclocking

It's all about power management chip with Adaptive Voltage Scaling, chip's firmware is programmed to limit frequency. I don't know is there way to change this by kernel.
[Galaxy Ace II Q&A, Help & Troubleshooting] mkel91:
it's impossible to OC our cpu via kernel because CPU's firmware lock frequency to 800mhz..
[Galaxy Ace II Q&A, Help & Troubleshooting] bogii4:

I'll say it again. All sources (even from St-ericsson) are provided by Samsung. I don't understand "St-ericsson source code myth".

OC depends now if we'll find a way to "tell" PRCMU to change frequency limit. It's almost impossible but there's chance ;)

[Galaxy Ace II Q&A, Help & Troubleshooting] astankov:
Good point - I also think that there is no sources from ST. Probably when some manifacturer like Samsung or Sony or whatever is decide to use this SoC in some device like ACE2 for example ST provide to this company document how this chip works. So then the company in our case Samsung starts making the needed source to make some working software. So current software is not capable of OC but if we have that document and understand all about our SoC I think we will be able to make it. Also good point is what effect will have on our device - will it increase performance or just drain more battery. For example if we have a PC with nice CPU but slow RAM clock and bad graphic card result will be bad and will not get any improvement if CPU is replaced with better one. In our case we cant change RAM or graphic card on our ACE2 so OC may result in nothing good. That is probably the reason why Samsung decided to use 800 instead of 1000 Mhz in our device.

Anyway this is just my opinion about the situation and will be happy if I'm wrong and we have real effect when OC become avalible.

Regards!

[Galaxy Ace II Q&A, Help & Troubleshooting] xXfreshXx:

[Galaxy Ace II Q&A, Help & Troubleshooting] michal89chz:
I dont think so... neo v/play/arc/s plus after OC to 1.9 Ghz can handle Nova 3 on max.

[Galaxy Ace II Q&A, Help & Troubleshooting] ken_alpha24:
Ive been reading these comments...

this is what i know about games...

first of all our games lag because of the GPU (it only has 1 core) thats why it isnt powerful enough to run HD games or blah blah blah

i think OC wont help solve the lags

so i compared Ace2 with S2... i know it is in different divisions but still LOL

S2= dual core Exynos Cortex- A9 1.2ghz / 2 core GPU Mali400MP

Ace 2= Dual core Novathor ARM-v7 Cortex A9 800mhz / 1core GPU MAli400mp...

GPU helps alot in processing games :) s2 scores 50% more than ace 2 in antutu but almost have the same things in it...
[Galaxy Ace II Q&A, Help & Troubleshooting] dels07:
could you compare with Galaxy S Advance, Galaxy S3 Mini, Xperia U or Sola which have 1 Mali 400MP?

Just barely handle HD games. They lag and crash. Since software modifications let us down. Then hardware modifications should do the trick. If you can replace the screen and digitiser or make them better then you can play mix and match with other internal components such as the CPU. Problem is that hardly anybody will be able to complete all necessary procedures for changing parts. It will also kind of isolate those who correctly upgraded their phones because custom ROMs and kernels will work differently for their devices. May even brick their devices. But I'm just putting my idea out there. I just think that the Ace 2 is an incomplete phone. I saw a gameplay video of Modern Combat 4 on the S4 and compared it to the Ace 2 and I got jealous. But. If all else fails. Then I'm gonna get a new phone.
