[10/19/2014] Safestrap-I337-3.75-KitKat-A01.apk [NB1/NC1/NI1]

[Initial Release] Safestrap-I337-3.75-KitKat.apk [NB1/NC1/NI1]

Changelog:

vA03 - [Current Version] Resolved issue where the Safestrap app would "force close" or fail to install after OTA updates. Setting SELinux to permissive is no longer required.

vA02 - Failed! - resolved "reboot from rom slot bug.

vA01 - Added Surge1223's feature setting selinux to permissive upon install and eliminating the need for the SELinux Mode Changer app.

v3.75 - Initial Release - Enabled ROM Slots.

Disclosures/Known Issues:

1) When powering down from the ROM running on a ROM slot the phone will hang. You must long-press the power button to shut down the device. I will debug as time permits.

2) Backups made with earlier Safestrap versions will not restore. You must make a new backup using v3.75.

3) Per Hashcode......."the system size is now not adjustable on 4.3. Samsung put in a verification that has issues if the partition size changes too much. So I opted to keep it exactly the same as stock."

I cant seem to get Safestrap installed. On Nl1 4.4.2, and am rooted. I downloaded the latest, and hit install. It says that it installs fine. Then I reboot and dont notice a changed splashscreen or anything?
[AT&T Samsung Galaxy S 4 Android Development] kevinco1:
For I337 users like myself, is there any benefits of running the I545 version of 3.75? Or is it recommended to keep using our model specific build for 3.75 SS?
[AT&T Samsung Galaxy S 4 Android Development] Soccerzubs:
Hey, I spent a few hours reading through this thread and wanted to clear a few things up.

I am on MF3 4.2.2 with Safestrap 3.65 and want to upgrade to KitKat. Now from what I read the previous way was to odin to MK2 4.3 and use the Deadly Venom KitKat Magic Tool to flash a 4.4.2 Rom. Now my question is, is that still the best way to get KitKat or should I just odin to NB1 and root it? Would I still be able to flash a GE Rom on NB1 or should I just stick to MK2 and use the Deadly Venom KitKat Tool?

I am basically looking to run a KitKat GE Rom and wanted to make sure this is the correct method. Thanks.
[AT&T Samsung Galaxy S 4 Android Development] IceTwig:
you need to make sure SELinux is permissive. This is to change it
[AT&T Samsung Galaxy S 4 Android Development] Galaxy*$4:
glad to know that we can flash rom slots now.

hey i got a stupid question, if something bad happens how can i odin back to stock then i got towel root.

i am sorry its been way to long since my last rom flash and i cant remember.
[AT&T Samsung Galaxy S 4 Android Development] Galaxy*$4:
yep operator error hits me again. same mistake as last time....

trying to fix a issue with carhd rom, couldnt use the phone app kept on saying contacts stopped... no mater what

turns out i was running the old v28 new is v31.... so downloaded the v31 while waiting on it to download, i decided to try to fix it, so did a full wipe including system. and hit reboot.. well guess what got nothing and now i have to odin back to stock. so looked through my pc must have deleted the files needed recently i did fine a zip file had all the files so unzipped that it was a pdf file and it didnt work , so have to wait until the files get done downloading .

and i got a crappy charger(s) one is worse then the other. and my 10ft charger wont even pwr the phone when its connected to the pc... it hardly charges the phone while i am using it using a ipad charger cord.

sorry for my ranting, it just one of them things.

edit found out i downloaded the wrong file. the mk2. used it before in the past, kept getting fail, now i am downloading the nb1 file. great...................................................... also download mode, shows that it encountered an issue and i have to use kies. but i can still download files to it, so 45min wait until download.

I was using my phone with navigation in the van and it got really, really hot. Ive checked around on forum there seems to be a lot of jokes but no answers. I'm running Goodness V10.0.4.1 stock kernel. I unlocked boot-loader and clean installed ROM from full wipe. I really doubt it's a battery problem because i just got the i535 two months ago and i dont really have any other heating issues.
[Verizon Samsung Galaxy S III] Wh1t3Rose:
Is it hot where you live? Do you charge your phone while using navigation? Do u leave phone in sunlight?
[Verizon Samsung Galaxy S III] pastapie:
Yes it is hot but AC on in van and not in direct sunlight it was on my seat. My question is it a kernel issue? It got really, really hot!
[Verizon Samsung Galaxy S III] Wh1t3Rose:
Only the Dev can answer that. Best way to find out is to try a different kernel
[Verizon Samsung Galaxy S III] pastapie:
OK, suggestions? I guess nobody is having this issues with goodness.
[Verizon Samsung Galaxy S III] Wh1t3Rose:
You would have better luck asking in the kernel thread. Just ask if anybody has overheating issues.

UCAMC3 vs UCAMH3 speed results

just another data point for folks... attached screenshot are the results from a quick modem speed test (using SpeedTest.NET). Just prior to upgrading my modem to UCAMH3, I ran speed tests on my current modem (UCAMC3)... then flashed the MH3 modem, and re-ran tests (same local server, immediately after flashing new radio). Results will obviously vary on your personal situation (geographic location, phone setup, etc); however for me the MH3 patch significantly improved my WiFi download speed (173%) and WiFi upload speed (24%). It was a basically a wash on MC3 vs MH3 HSDPA speeds. Ran 2 tests each on WiFi and 2 tests each on HSDPA (on both modems)... then averaged the results. Ping speeds were also significantly improved. Take it for what it's worth, but for me, appears the patch addressed WiFi speed improvement.

Thanks to 147aaron (for pulling the MH3 modem.bin) and Guitarboarder28 (for packaging the flashable zip).

What is an RIL?
[AT&T Samsung Galaxy Note II] chris.l.naish:
RIL = Radio Interface Library...opinions on this vary greatly, but typically you should use a matching RIL for your modem for best results and battery life.
[AT&T Samsung Galaxy Note II] inspron:
Interesting, learn something new everyday. So how does one go about installing RIL?

Re-apply AWS mod.

I guess I need to re-apply the AWS mod after updating Radio.
[AT&T Samsung Galaxy Note II] mashuto:
So I recently realized I was running an older modem UCAMA4 and figured I would give this a try, thought maybe it would help out with signal strength or boost speed.

On first boot during my speedtest, com.android.phone (or whatever) crashed. So I went back and wiped my caches and attempted it again.

I ran quite a few tests, and truth is, I really do not see much if any difference between the old and new modem. Speeds are all fairly consistent and any real differences seem to be normal variations between tests. Signal strength seemed to drop very very slightly, and although consistent across tests, it is nothing I would think is noticeable at all. If I had to say anything I would say the new one is worse due to slightly slower speeds, slightly worse signal, and the fact that uploads in the speed test seemed to be choppy or spiked a bit.

I also tried to keep my phone in the same place between tests to avoid anything external that may have affected the signal strength and therefore the speed.

Also, if it makes any difference, I am running the latest version of Beanstalk.

I am attaching my speed test results.

I ran the MH3 update last night and pulled all the files from /system. If no one else has done so, will post a set of updates in three groups when I get home tonight:

- everything but apps (you can pull RIL related files from here)

- changes from MC3

- the whole sheebang (for any devs who want to get their touchwiz on)
[AT&T Samsung Galaxy Note II] wase4711:
its not unusual for a modem to do nothing for speeds; thats the reason that once I have a working modem/radio setup, I never update it..."leave well enough alone", if it ain't broke, don't fix it", is my philosophy on phone radios....
[AT&T Samsung Galaxy Note II] mashuto:
I wasn't necessarily expecting it to, just wanted to share my experience with it. At the very least, it seems stable and hasn't caused me any issues.
[AT&T Samsung Galaxy Note II] karlkarloff:
Awesome, I'd like to get the whole sheebang for sure, just to mess with. Thanks! Flashed the radio this morning. No problems so far, speeds seem unaffected, but time will tell on that.

No problem on the cross link.

As for RIL related files - here's what I've found that looks related:

/system/bin/sec-ril

/system/bin/dttexe

/system/bin/efsks (*)

/system/bin/qcks (*)

/system/lib/libril-qc-qmi-1.so

The two marked with (*) have more to do with the efs partition that with RIL specifically and could perhaps be skipped. In general, my preference is to keep closer to a stock config and have all the lib and bin files in sync with the the rest of the files in /system. YMMV depending on the ROM you are running.

The files can be pulled from the smallest of the ZIPs I posted and copied manually to the folders above or someone can create a flashable zip. Either way permissions need to match the other files in the respective folders. For /system/bin it's 0755. For /system/lib it's 0644.

Just to share. I lost all data after flashing this. Had to do a factory reset to get it working again.
[AT&T Samsung Galaxy Note II] 147aaron:
This is just the modem, it doesnt touch any data on your phone. All it does is update your current modem on the phone and thats it. So I don't know why you would run into those problems. Any chance you accidently hit a different install zip file? Or do you have the I317M (Canadian verison of the i317)?
[AT&T Samsung Galaxy Note II] onesikpuppy:
I'm sorry, I wasn't very clear. What I lost was the ability to access network date, I could make calls and send texts but any app that required a data connection would not work. Could not access the internet by WiFi or via at&t network (3G).

I tried clearing cache, flashing an older modem and restoring prior backups of different ROMS but that did not fix the problem. I had to do a full factory reset to get any kind of mobile data connection to work.

Not really complaining, I know that's a risk of flashing. It was just an FYI
[AT&T Samsung Galaxy Note II] 147aaron:
Well I apologies for any problems you ran into, I haven't ever heard of that happening before. I am glad you got it up and running again tho. What rom were you using when you flashed this?

Well I.. Messed up and I need help on fixing this...

I have a i317 variant. My problem is I don't know if its considered Rogers or what. Carrier is Claro PR. I saw there was an update for the modem for the i317 so I flashed it. It said not for canadian carrier.. I'm in PR so I figured.. Now beanstalk 4.2.2 keeps bootlooping even after reflashed. I resourced to updating the modem because I wasnt getting any internet for some reason even after having the apn correctly.

Edit:

Just tried this Modem http://xdaforums.com/showthread.php?t=2274854

I get the same bootloop seems I do have a Rogers or a canadian or w.e >.< gota keep trying modems I guess until someone points me in the right direction.
