[SOLVED] On Reboot, Kernel keeps resetting to MM

===Solved! Just overwrite your old SafeStrap by installing the SafeStrap.apk included at this thread:
http://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370
and be sure to have BusyBox installed prior to overwriting the SafeStrap install, otherwise it will not actually work.
Unsure if related, but if problem persists connect your microSD directly to a PC and look for ".MM_KERNEL_SS-FF_Flashable" folder
===
So I had followed jkruse's locked bootloader guide to use a stock MM ROM with SS support. After using it for a while, I decided to go back to OptimalROM. Unfortunately, every reboot results in stock recovery. I found I can just flash a PB1 kernel through Odin and that fixes it for now- however on the next reboot BAM- back to the same problem.
I assuming this is caused by the current SafeStrap I have installed- which was linked in the MM for locked bootloaders thread.
How can I prevent the kernel from being overwritten every reboot?
On a side note, where can I find the latest stagefreight fix zip for 5.0? I have tried a few but they only seem to work on the 5.1.1 ported ROMs. Tried Stagefreight_Fix_02_Nov.zip and gets stuck at boot. Same situation with Stagefright_Fix_v2_i9505_i337M.zip.
Surely there is a ported fix somewhere for 5.0 roms?

Can you not flash PB1 thru Odin and just root and install OptimalROM via FF that way

I can always resort to that, but I am trying to figure out what it is that keeps reflashing the MM kernel on reboot. I assume its the MM_Safestrap.apk, but only @jrkruse knows for sure

It appears I was right on the money! After grabbing the SafeStrap.apk from the OK3-V5 root package and installing that version of SS over the MM specific one, I no longer have the issue! I also opened my microSD directly on my computer (not connected through phone USB) and deleted the .MM_KERNEL_SS-FF_Flashable (note the .) folder.
Hope this helps anyone else who downgrades.

Flashing on 935F

Hi all.
I have the 935F International on it's way to me, delivering in the next day or so
By all accounts the 935F is already unlocked. To prepare, I have already downloaded Odin 3.11.1, CF's root file, TWRP twrp-3.0.2-2-hero2lte tar, and a custom ROM and bootloader/modem files.
I'm not a noob to flashing, just newish to Samsung.
What is the best way to start? Boot into stock, enable bootloader unlock on developer options, run Odin and flash TWRP, then CF's root file? Also, I want to run unencrypted - format data using advanced wipe 'yes' method?
The ROM states it sets root on installation. Do I then need to flash CF's root file?
Further, how are bootloader/modem tar files flashed? Is it as simple as selecting BL for bootloader, although I don't see anything for the modem??
Finally, what is the actual order of all this? I'm thinking: TWRP first, Format internal data second, CF root third, ROM flash from TWRP fourth, reboot to download mode from TWRP and then flash modem/bootloader last. Then reboot all together to set the phone up?
Thanks and any help is appreciated

1. Update to latest firmware
2. CF-Autoroot
3. TWRP
4. Flash no-verity-opt-encrypt.zip, wipe data.
5. Reboot recovery, mount system.
6. Wipe all except internal and external sd.
7. Flash your ROM

Thanks for the info :good:
When you say update to latest firmware this is Bootloader and Modem yes?
Steps 2 & 4 - just having done a little more research, are these outdated now?; as TWRP (latest) now fixes encryption and the ROM will inject (for a better term ) SuperSU when installing it? Or will this still need to be done irrespective of using the latest version of TWRP and ROM?
Cheers and thanks :good:

If you're not new to rooting and custom roms, pretty much all you need is to unlock OEM in Dev Options in Settings, Restart the device and hold Vol Down+Home+Power to get into Download Mode and press Up at the blue screen. Plug in your USB to your phone and run the tool on your PC.
Once Rooted, its business as usual. You don't need a guide to install TWRP, just install the Flashify app and let it do it for you, and then have no-verity-opt-encrypt.zip handy to flash. I know no-verity-opt-encrypt.zip is essential if you flash TWRP through ODIN, but not 100% sure if you should if you flashed TWRP through Flashify, I always flash no-verity-opt-encrypt.zip regardless so I unno.
Also if you find yourself in a semi-bricked situation where you can't figure out your problem, as long as you have Download Mode, you'll always have a way to get back to a working device. Samsung Smart Switch for Windows has an Emergency Mode that will revert your device back to Factory Conditions.

I've been doing things this way since day 1 with no problems. My advice would be to do it the same way. I can assure you a solid install ;]
Yes, firmware is bootloader & modem. Great thread for this is here http://forum.xda-developers.com/s7-edge/how-to/official-stock-firmware-update-odin-t3335065

stock_N910VVZW2CPG2_VZW updated with FlashFire, Rooted

This is too complicated for me to explain everything but here is my Cheat Sheet !
If you have been flashing you probably already have these files.
1. Odin SamMobile N910VVRU2BPA1_N910VVZW2BPA1_N910VVRU2BPA1_HOME.tar
reboot and factory reset a few times if needed to remove custom icon
2. Odin hsbadr's N910VVRU2BPA1_N910VVRU2CPD1_FullFirmware.tar HERE
3. Unlock with the samsung_unlock_n4-fix PROCESS use SIM card for data. Wi-Fi will not work at this point.
4. Odin twrp-3.0.2-0-trltevzw.tar Uncheck Auto Reboot, Manually boot into TWRP
5. Odin hsbadr's N910VVRU2CPD1_StockRestore.tar HERE
6. TWRP BETA-SuperSU-v2.71-20160331103524, Factory Reset, boot system
7. Use FlashFire to Flash firmware package SamMobile N910VVRU2CPG2_N910VVZW2CPG2_N910VVRU2CPG2_HOME.tar
( ! System and Cache only ! )
SAME as the thread Safe System Updates_6.0.1 MM_FlashFire, dm-verity work around, SM-N910V
Except Now that SamMobile has posted 2CPG2 I was able to skip steps and go straight to Flashing the firmware package with FlashFire.
No need to do over the air updates.
-----------------------------------------------------------------------------------------------
Note: I was able to skip the recommended rooting of 5.1.1
I did not do the unlock using Kingroot until step 3 and I did not permanent root with Super Su until step 6.
No matter how you get there the phone has to be on [Firmware] [MM] [6.0.1] [RetEd/DevEd] Safe Upgrade to Marshmallow [N910VVRU2CPD1] then you can use FlashFire.

I have been flashing and playing with roms on many devices and there is something I don't understand. Why can't someone inject root into the factory tar file and make the upgrade a much simpler process? If our devices once rooted are considered the same as a developer edition, why can't we simply flash whatever image we want?

PaulPizzRom is just as good......

OR BETTER!!!!!!

Think you could fix your 'HERE' links in your OP?
hsbadr's CPD1 is already rooted or something? I just re-went through the unlock process and i thought if you flashed a stock firmware it re-locked the bootloader?

Can i flash stock rom 5.1.1 by flashfire?

Could someone please upload the ota zip file only

I'm on 5.1.1 PA1/PD1 with TWRP installed and would love to move to 6.0...would I have to start all over to accomplish this or could I begin in the middle of your guide where I am?
thanks!!
Nevermind..I'm on 6.0

Many thanks!

Need help flashing ROM on I545

Hi it is the first time I am flashing Android ROM. I have done some reading already. Before I start, I still have a few questions and also want to make sure I am doing it right.
I own the Galaxy S4 Verizon I545. It is running Samsung ROM Android 4.4.2, Baseband I545VRUFNC5. My goal is to flash a new ROM with recent Android versions, hopefully 7.1.1 (but I would settle with Marshmallow if that is more stable), it can be close to AOSP, I don't need ROMs with extra features.
In my understanding, the bootloader is locked, it will only load signed kernels and recovery. And then the kernel would load the system. In order to flash the system, it is best to flash the recovery first with TWRP. TWRP is modded with loki hack so it would load with the locked bootloader.
So here are my questions:
1. Does it matter which firmware/baseband I am currently on? For some phones (LG G2) I heard newer firmware fixed the loki hack. Should I update to the latest Samsung rom or leave it at NC5?
2. I don't see many ROM posted for the i545, which one is the most recent and reasonable stable? The Cyanogen website is down, should I try LineageOS?
3. I see different instructions for flashing TWRP. Can I flash it with just Odin? Some instruction mentioned rooting the phone first with KingRoot or other root, and then use dd. Does the phone have to be rooted? (I prefer not to if it is not necessary)
4. If after I flashed recovery, it fails to boot into TWRP, what can I do to restore everything to default?
5. The kernel will be untouched in the process right? I am only flashing recovery and system ROM, and the kernel will work fine with the new system ROM?
Here are the step and software I plan to use:
0. reset the phone to factory
1. use Odin to flash TWRP 2.8.7
2. download a ROM compatible with I545 and place it on the phone
3. flash the system using TWRP
Any feedback would be appreciated.
PS: Also I have a LG G2 D801. I would flash that phone instead if it is easier. I just want to get started and learn some things along the way.

https://forum.xda-developers.com/galaxy-s4-verizon

Oh Sorry. Didn't notice there is another forum. Should I repost there?

Yes.

1. Yes, it does matter. As you said, newer firmwares have fixed the exploits which make the phone harder to hack.
2. Any ROM should support your phone. They are generally unified.
3. In the name of anything holy, do not root with KingRoot. If you want to root, then the only way to go is CF-Auto-Root.
Rooting is sometimes necessary because recovery won't always install with Odin.
4. Flash stock ROM.
5. Kernels are specific to ROMs. So no, the kernel won't be untouched.

LineageOS on a vzw Galaxy S5?

Can I put LineageOS on my Galaxy S5 using SafeStrap? If not, would Odin do the trick instead?
What, if anything, do I need to do to maintain root?
Do I need to unlock the bootloader before flashing the ROM?
Do the steps in the above link work on unlocking the verizon bootloader or will I make a brick?
If there's a link to getting LineageOS onto my Verizon S5 while keeping root please point me in the right direction. Thank you.

you first need to root then unlock bootloader then install twrp then flash Lineage and Gapps and your all set , all information regarding how to root and unlock bootloader are in the vzw section , do make a full back up of your sdcard(micro sd card) to your computer because unlocking the bootloader will wipe/format your memory card(keep that in mind)
also i suggest you update your modem and bootloader , just in case you would like to test the ported rom which most of them run on a higher bootloader and with a old bootloader you will face issues with wifi and nav buttons specially with the vzw variant (i also have a vzw) , update it to i think the highest so far by @jrkruze is qf2 , for example the skiesrom (a s8 port) runs on a qf5 bootloader but updating vzw bootloader to qf2 fixes the wifi and nav button bugs.
Good Luck and also do properly read the instructions word for word.

I'm so grateful for your response. You've been down this road and know the traps. I believe my original post has the right thread on unlocking the bootloader for vzw, and I appreciate the warning about it erasing the micro-sd card.
Two follow-up questions:
Where can I find the update for the modem?
Also to avoid the wifi and nav problems, do I want the QF2 or QF5? And where do I find those? Here it says to use latest bootloader (QA1) with QF2 modem. Does that make sense? If so I just need to know where to find those.
Thank you again so very much.

The Latest bootloader (after you unlocked your current bootloader) : https://forum.xda-developers.com/showpost.php?p=73734257&postcount=3143
latest modem : https://forum.xda-developers.com/showpost.php?p=61802396&postcount=1 ( use the ones in the odin section , you will need to be bootloader unlocked and have odin+latest samsung drivers installed)
latest twrp : https://dl.twrp.me/klte/ ( the ones that ends with .tar are for flashing using odin , since you dont have twrp yet but flashing twtp comes last after rooting and unlocking bootloader and updating bootloader then update the modem then odin flash twrp then have lineageos and nougat gapps on memory card. reboot while holding vol up and home button to reboot into twrp to install lineageos system then gopengapps , afterwards you can install magisk to have root access on lineageOS as well .
p.s after you unlock bootloader and the system reboots normally return to download mode then use odin to flash twrp , i just noticed(remembered that latest bootloader update uses twrp and not safestrap recovery.
to unlock current bootloader : https://forum.xda-developers.com/showpost.php?p=71202995&postcount=3

Thank you so much. So if I understand right it's:
1) UNLOCK bootloader
2) UPDATE bootloader (latest is QF2)
3) update modem (latest tar was QI2)
4) flash TWRP from Odin (you linked to klte version; qualcomm but I have vzw)
5) install LineageOS and gapps from TWRP
6) install magisk from TWRP to get root
Is that correct?
Correct bootloader and modem versions?
OK to use klte for Verizon?
Magisk is for root, done last, and not superSu?
If all those are Yes, then I guess the prep work is done and now I just have to bite the bullet, do a safestrap and titanium backup and dive in.
Thanks again - I really do appreciate it.

yes thats correct , also there is no vzw variant of lineage since vzw is merged under klte , so every rom you download the one you have to choose is klte unless the dev make a build for each variant but not likely to happen anymore.

A very basic assumption may have been overlooked, but it seems the CID on my lollipop PB1 is 11 Toshiba eMMC. Method 2 of unlocking stopped at step 4 with an error in the terminal screen indicating this is only for Samsung eMMCs. Is it possible to unlock an 11, and if so, where would I find those steps?

sadly cid 11 cannot be unlocked , best option is to only change current S5 with another S5 and hope its a CID 15 , or sadly get another phone but check xda forum to see if it has any latest custom roms and bootloader can be unlocked.
But for CID 11 theres no unlocks for those , only thing is safestrap roms that allows you to run ports like PhoenixRom and other stock but modded roms but using safestrap

Thanks you so much again. How can I tell which ROMs are stock I can use in safestrap (like Phoenixrom) and which are custom I can't use (like LineageOS)?
And if I have a safestrap backup to my sd card of my stock lollipop and don't like phoenix (which seems to be MM) can I restore from safestrap back to my stock LL?

that im not sure about that so i cant give you any pointers since i have not done anything with safestrap besides the process to unlock the bootloader.

Thanks anyway. It seems it should work, since safestrap won't disappear. Maybe I should post a new thread. Thank you again for all your time.

I am also essentially looking to install LineageOS on my Galaxy S5, but before proceeding, I just wanted to make sure that what I'm looking to do is correct. Currently I am running an old version of PhoenixROM with an old unlocked bootloader. I know that I will need to update the bootloader in order to prevent issues, such as wifi not working.
Should all I need to do is follow JKruse's instructions here, flashing LineageOS as the last and final step? I'm hoping that it is this easy, but I do have my doubts and that is why I am asking on here for advice.
Thank you to all in advance!
