[Android Q&A, Help & Troubleshooting] puppybutt:
Happy Friday, everyone.

A couple months ago I followed the step-by-step process outlined on androidforums.com (Samsung Stratosphere 2 SCH-i415 (4.1.2/Jelly Bean/MA3) rooting guide -- I would post a link but I can't) to root my Verizon Samsung Galaxy Stratosphere 2 device.

It seemed to work well enough, and I proceeded to uninstall most (if not all) of the bloatware from my phone.

For a few weeks now, Verizon has been attempting to push an OTA Jellybean update to my device. It keeps failing, and I'm at a loss for what to do next.

Others seem to have run into a similar roadblock, and according to janeric2 from androidforums.com, "... it appears that loss of ability to install updates after rooting can happen if you remove some of the pre-installed apps on the phone[.] Anybody have an idea how to get those back? From what [I can tell], it's not as simple as reinstalling them from the Market - you apparently need the original apps."

That being said - does anybody have/know where to get the original android Jellybean install, or know of any other methods to get this update to work on my rooted phone?

Thanks in advance for any help or insight you're able to provide.

In ODIN do you flash this as a PDA like the previous root file or as a PHONE?
[Android Q&A, Help & Troubleshooting] kado01:
select .tar file using PDA button.
[Android Q&A, Help & Troubleshooting] mattshrap:
I got it rooted using the tar including CWM. However CWM was not installed on my phone. I went to the play store and downloaded CWM and rebooted the phone. I'm still not seeing any custom recoveries installed in CWM. All it says when I go to Manage backups is: the directory /mnt/shell/emulated/clockworkmod/backup doesn't exist and that I can change the directory in backup settings.

---------- Post added at 11:36 AM ---------- Previous post was at 11:25 AM ----------

I think that I figured it out. I currently rebooted the phone into reovery mode using CWM and it's creating a custom backup of the current ROM.

Which custom ROM's will I be able to install and use with the Strat 2 safely once this process is complete?

Can someone confirm that you can still downgrade from the latest bootloader to an older one? This is a clue as to "how locked down" the device is and whether the loki bootloader exploit would work
[Android Q&A, Help & Troubleshooting] Oface82:
I just wanted to see if you ever followed up on the idea of CM port for the Strat II. I have two, one rooted one not, and would be glad to send you anything you might need! Thanks!
[Android Q&A, Help & Troubleshooting] :
You're offering to send me a phone? Twist my arm why don't you. ;) I'll send you a pm.

I still would like someone to confirm the latest bootloader can still be downgraded, this bears greatly on the bootloader unlock (which I will start on in anticipation of testers)
[Android Q&A, Help & Troubleshooting] :
Lol or even if you just meant testing I'll be sure to use you. Just realized you probably meant that
[Android Q&A, Help & Troubleshooting] Oface82:
Haha yeah I meant I wouldn't mind serving as a guinea pig. I'm afraid I don't have any superfluous Strat 2s lying around that I could send you :) In answer to your question, I used the method outlined by Kado01 previously to root and believe that it does in fact the downgraded bootloader. Please pardon my ignorance, but how could I go about confirming that for you? Also, I was wondering if you knew of any custom kernels compatible the Strat to allow overclocking. I feel like being able to overclock is one of the big advantages of rooting but there don't seem to be any kernels that support it for our device. Thank you so much for your time and effort, much appreciated!
[Android Q&A, Help & Troubleshooting] lemayautocare:
Count me in for testing. I have two of these rooted and unlocked and would love to see further development on them
[Android Q&A, Help & Troubleshooting] :
My development aegis2 should be coming from ebay in a day or two. In the meantime, I still need confirmation that a device flashed with the MF1 bootloader can still be downgraded after that fact.

---------- Post added at 11:30 AM ---------- Previous post was at 11:21 AM ----------

Does the first image contain the MF1 bootloader? And are you able to flash the downgraded bootloader after flashing this? And which files are you changing out to downgrade, is it the full bootloader or ?
[Android Q&A, Help & Troubleshooting] Oface82:
I can tell you that I rooted using the second image and that my bootloader is definitely unlocked. Unfortunately I just can't which version I was on when I rooted the phone and thus stopped receiving updates, but I am 95% sure that I was one MF1 which would mean that the bootloader is indeed downgradable. Again though, I can't swear to it
[Android Q&A, Help & Troubleshooting] :
The reason I'm asking is I do not intend to use the downgraded bootloader for CyanogenMod but rather a modified version of the latest and I want to make sure it doesn't permanently lock the device, like the newest bootloaders do on the Galaxy S 4.
[Android Q&A, Help & Troubleshooting] kado01:
Yes.

Yes.

I have downgraded only aboot.mbn

---------- Post added at 03:04 AM ---------- Previous post was at 02:09 AM ----------

Basically, bootloader of Strat 2 is locked completely.

But, only bootloader of LJ2, partially unlocked.

That meanings, able to execute unsigned image on recovery partition only.

I have tried Loki boot method on Strat 2. However, it is not good at the moment.

For reference, I have tried the following.

Place a non-signature image on boot partition, place a signature image on recovery partition.

Then, booting recovery (holding vol up key).

An error message displayed as "not authorized", it will not boot until flash original kernel via Odin.

From this, I guess, bootloader of Start 2 is checking kernel's signature "before" loading kernel or recovery image.

In this case, Loki method is not useful, I think.
[Android Q&A, Help & Troubleshooting] :
ok after talking to the d2vzw guys, I have a much better idea of the unlock methods. What you're talking about is actually kexec, and it may be possible to use on aegis2, although your tests are certainly a strong data point. Loki works a bit differently, and it's what I'd like to use. You start with disassembly of aboot (the newer one, not the old one!) and look for the start of the check_sig() function.
[Android Q&A, Help & Troubleshooting] kado01:
Got it!

In above, it was a big misunderstanding.

I try again Loki method for MF1 bootloader, everything is works fine.

additional information of loki_patch.c are as follows.

.vendor = "Verizon",
.device = "Samsung Galaxy Stratosphere II",
.build = "I415VRBMF1",
.check_sigs = 0x88e0fe70,
.hdr = 0x88ed32e0,
.lg = 0,
[Android Q&A, Help & Troubleshooting] royalflush5:
so you managed to unlock the bootloader? if you guys need another test phone I'd help
[Android Q&A, Help & Troubleshooting] kado01:
I have changed rooted system software package for Loki boot method.

Converted recovery image by loki_patch.

Including loki_flash command.

And changes on CWM.

Based CWM(touch) 6.0.2.3.

Home(select) button and back button is enabled.

Fixed boot logo.
[Android Q&A, Help & Troubleshooting] kado01:
Yes, bootloader was unlocked practically.

As a demonstration for Loki method, I was prepared unsecure kernel. (adb is run as root)

Install as following.

> adb push I415MF1_UnsecureKernel.lok /sdcard/
> adb shell
$ su
# loki_flash boot /sdcard/I415MF1_UnsecureKernel.lok

I hope that many people to create a custom kernel.
[Android Q&A, Help & Troubleshooting] Oface82:
bootloader and kernel

Please excuse my ignorance yet again, but I have 2 questions.

1) Am I correct in thinking that flashing the unlocked bootloader via odin will not wipe my data? I don't think will but not sure.

2) Please explain exactly what the unsecure kernel download is. it's not actually a custom kernel but rather one that you were using to demonstrate the bootloader?

Again, thank you so much for your patience and all the work you've down. I've seriously learned so much from your posts and it is appreciated.
[Android Q&A, Help & Troubleshooting] kado01:
Bootloader itself is samsung genuine completely.

Because this Loki method is use the exploit of latest bootloader, revert to original bootloader.

Also, this package will not any effect on userdata.

This is custom kernel actually.

Difference to original is minimal, however, important, it is to prove execute kernel that is not signed and modified.
[Android Q&A, Help & Troubleshooting] Oface82:
I just finished the odin flash of the new system image. Everything was successful but I have a question about the CMW touch. It seems that I can no longer use volume up+home+power to boot into CMW recovery so I downloaded rom manager and have been using that to do so. Is that the preferred method? Also, I will be flashing the kernel soon to test that. Will it be necessary to flash back to stock afterward? If all goes well I'm hoping someone will compile a kernel with overclock support. Thank you as always!
[Android Q&A, Help & Troubleshooting] kado01:
I made a overclock kernel.

It works 1.9GHz.

Enjoy!
[Android Q&A, Help & Troubleshooting] Oface82:
Can this the OC kernel be flashed via CWM or Odin? You rock buddy!
[Android Q&A, Help & Troubleshooting] royalflush5:
How stable is this at 1.9GHz? Is there a way to change the clock frequency?

Keep up the great work!

I believe you can flash the zip with cwm.

EDIT: I tried to flash it and it aborted, said it was bad. DId I do something wrong?
[Android Q&A, Help & Troubleshooting] Oface82:
Same here. I have no idea how to push it with adb but I'm gonna try researching it.
[Android Q&A, Help & Troubleshooting] kado01:
Same as above.

unzip it and using loki_flash.
[Android Q&A, Help & Troubleshooting] kado01:
Well, I have convert to be able to install from CWM.

And furthermore, overclocked GPU 400MHz -> 480MHz.

Unfortunately, I do not know how to vary maximum clock at the moment.

Update: fixed
[Android Q&A, Help & Troubleshooting] Oface82:
Flashed successfully. Unfortunately it just doesn't wanna run stable at 1890 mhz and without a way to set max speed (setcpu and rom toolbox both failed to work) that's where it spends most of it's time. Almost there!
[Android Q&A, Help & Troubleshooting] kado01:
It was able to change maximum frequency after clean build.

Installation Instructions

For a newb like me, could someone explain how to install this? From previous posts I am getting that this unlocked overclockable kernel should be loadable via ODIN. I am just not certain what settings to use on ODIN. Instructions would be very greatly appreciated! Thanks a lot.

I hesitated to flash as a PDA via ODIN, and I tried using CWM loading as an update.zip --> this failed.
[Android Q&A, Help & Troubleshooting] Oface82:
Download to your sd card then flash via CWM. Not as an update, just choose: Install zip from sdcard> choose zip from sdcard> Download/ > update_i415mf1_unsecureOCKernel.zip> Yes- Install.

good

Hey guys!

So I'm completely new to this. I have the Galaxy Stratosphere II and I'm wanting to root it, but I have no clue how. I'm not too good with all the tech talk :( If someone has, or would make a truly step by step tutorial for me, that would be just fantastic. A video would be best, but anything would be fine. I think I'm on the right track, but I really don't wanna try anything without knowing for sure, or else I might break it, and they're expensive! Also, I thought "rooting" was all you had to do? I read about people "unlocking bootloaders" and stuff? Can someone help me out with that too? Like, what's the difference? I Just want to be able to get rid of all the preinstalled apps and maybe put on a new ROM (I think that's what it's called), cause those seem pretty cool. Also, would I lose any of my data? Like messages and stuff? Sorry, I know I'm asking a ton of questions! Thank you everyone :)
[Android Q&A, Help & Troubleshooting] Oface82:
If you want to use Odin then flash the kernel through the PDA slot and make sure only Auto Reboot and F. Reset Time are checked under options. If you'd rather use CWM, which I personally think is easier, then follow these steps:

1- Download the kernel to your phone.

2- Boot into recovery mode and select the following: Install zip from sdcard, Choose Zip from sdcard, Download, update_i415mf1_unsecureOCKernel.zip, yes.3

3- Once it's done flashing select go back, reboot now.

4- Enjoy
[Android Q&A, Help & Troubleshooting] jdshewey:
Since this seems to be the official thread for all things Strat 2 I'll post this here. I did a physical teardown of my Stat 2 and did some analysis of the chips on the board:

jdshewey.blogspot.com/2013/09/stratosphere-ii-sch-i415-teardown.html

The most notable thing to me was that this phone was basically the same as the Samsung Relay 4G. This may be a lot of the software for that phone may be compatable. For example, I see that the Relay has Cyanogen Mod working for the Relay (github.com/TeamApexQ/apexq/wiki) which means it *should* work on the Strat II.

I'm making another blog post with links to some missing software pieces, namely the PIT file for the Strat II, aboot.img for the MA3 (4.1.2) update and the modem from the MA3 image. I'll post the link soon, so be sure to look for it. Does anyone have a modem for the LJ2 (4.0.4)? It appears that you can unlock a locked SIM on the LJ2 modem, but you definitely can't do it on the MA3. I tried downgrading to 4.0.4, but I get a black screen. Not sure why. I think it needs to have cache and SIM cleared after downgrade...

Lastly, it is worth noting the Strat II does not work with the standard USB Jig. If anyone can figure out how to get UnBrickable working with this phone or a USB Jig, That would be much appreciated since I am currently bricked due to flashing the wrong modem.

P.S.

Sorry the links aren't clickable. I don't have enough posts yet, so XDA won't let me do links as an anti-spam measure.

little help?

Hey guys. I know this is absolutely not right place to be asking this question but being that there are so few of us on the Strat 2 I didn't really think there was anywhere else I could get help. Anyway, here's the problem. I accidentally erased the fonts folder from our rom and now i'm stuck in a boot loop. Stupid, I know. Nonetheless I just need a copy of that folder from somebody so I can push it back to my sd card and be good to go. Can't tell ya how much I'd appreciate it if somebody would take the time to pull a copy of that folder and send it to me. Thanks in advance guys!
[Android Q&A, Help & Troubleshooting] Oface82:
Thanks again so much for your work on this! I have but one more request of you if you would be so kind. In order to take advantage of the overclocked GPU i downloaded Android Tuner Pro as it is the only I can find that offers control of the GPU and CPU. Most only seem to control the CPU. Well once I got it downloaded it said that the kernel did not offer a range of frequencies for the GPU and that I should request support through the app settings, which i did. The nice people there rssponded immediately but said they would need this info from the kernels developer so they could fix my problem. I'd greatly appreciate your help one last time!

Hey everybody,

I live in the UK and I'm desperate for a relatively new slider phone (we don't have any over here)

Of course I would like to root, but I'm more interested in unlocking the sim. Is there a way to unlock it?

Thanks for the rooting info guys!

Since this is the only place I have found meaningful information on the phone, I was wondering if anyone has managed to get usb otg host working? I see that verizon lists the phone as being able to use it, and using the app "USB Host Diagnostics" I can see that the kernel and android api claim support, yet I can get nothing to work via my usb otg cable. I've tried "stickmount", and "usb otg helper" without success, and mucked about a little. lsusb gives nothing, and there is nothing in /dev that looks like a usb device. /dev/bus/usb is empty. I have seen some posts around on mucking with some files in /system/etc/permissions, but they made no difference.

Also, does anyone know if we can take this latest update, or will it effect our root?

And another also, does anyone know if SDXC cards (>32gig) work in this phone? I seem to find conflicting info on this.

Thanks again!
