Just need a bit of help getting going - Verizon Galaxy Note 4 Q&A, Help & Troubleshooting

So Ive searched around and I just can't find a definitive answer so here is what I got.
I understand that this here; is how you use marshmallow with the new bootloader unlock and root: http://forum.xda-developers.com/not...t/howto-bootloader-unlock-upgrade-to-t3398144
I also know that I have to do this exploit first to unlock the bootloader: http://forum.xda-developers.com/note-4-verizon/general/note-4-verizon-bootloader-unlock-t3358913
My issue is I ended up getting forced OTA 2 weeks ago. So my current question is, Do I have to roll back to lollipop? Is root/unlock even possible for me? If so, How do I do that since I haven't rolled back before. Its been a while since I've been into rooting/roms. Is there a link to doing it for marshmallow to lollipop? Also what about the firmware?
Current Stats:
Model: SM-N910V
Baseband: N910VVRU2CPD1
Android Version: 6.0.1
Build: MMB29M.N910VVRU2CPD1
Kernel Version: 3.10.40
I just need an answer since Ive been reading threads the last 2 hours. Its confusing since the titles of most are how to unlock bootloader THEN goto marshmallow. Thanks Guys!

I think I solved it myself. Looking like I'm effed with this bootloader. Since I don't think its rootable or unlockable.

You can try to roll back to 5.1.1 by flashing the full firmware (thanks, hsbadr!) using ODIN. You can unlock the bootloader on this version.
The question is, will your phone let you. In another thread, the success rate appears to be something less than 100%. I don't know what the harm would be... if you can't do it, ODIN will likely fail. At any rate, the attempt is on you. I can't be responsible for what happens.

I did it just trying to get cyanogen to work with wifi and data/cellular to keep. However my phone is dev now and TWRP is installed.

Just frustrated right now trying to get Wifi to work. It looks like its suggested to try Flashing MM Stock, Reroot and Re-unlock bootloader here:
http://forum.xda-developers.com/not...t/howto-bootloader-unlock-upgrade-to-t3398144
Then use TWRP after all that.

Just make sure you're paying attention to what you're flashing. There are only three roms in the verizon development section that are able to utilize the 6.01 bootloader and modem. JASMINE ROM, PAULPIZZ 6.01 Beta and Cm13. The other roms are ports based on 5.1.1 so you may need to stay on the previous setup until more roms are updated
Tip the OP usually states what works/does not work and updates when things are fixed . The information changes quickly so sometimes you may need to read the thread from the end back to the beginning to see if your issues have been addressed

It was actually super simple once I found the thread on how to go back to 5.1.1 then how to take that and go unlocked w/ marshmallow chain. Last thing to figure out is disabling OTA on Jasmin ROM

Do not take APH1 Update!

After taking the APH1 update on my phone, I can no longer downgrade to PG5, and I also can't flash the PG9 U firmware. I don't know what Samsung/Verizon did, but it's ridiculous.
I'm now stuck on the APH1 firmware and can't get on the U firmware at all.
I haven't tried rooting, but there is no Odin firmware for APH1 yet, so I'm not going to try until there is, so that if I mess up my phone I can fix it.

It probably incremented the bootloader. I upgraded to it because I am just losing interest in root all together. Somebody will chime in with a more technical explanation.

Agreed. For some reason I just don't really care about rooting the S7. Maybe I've just rooted too many phones and lost interest.

For me a lot of it is this is not the most conventional root, not very stable for me and battery life suffered a lot compared to stock, and flashing U firmware has not been very cooperative for me.
So thoughts.... I am on the latest U firmware on my 930V. Should I consider flashing back to the stock Verizon rom? Everything is working great. I do plan on jumping ship from Verizon in the next year or so. I am blown away at how well this phone runs stock and only flashed the U in preparation to take it to another carrier afterwards. Is this a bad idea?
Tried to live with root, but the battery and stability was horrible. Now, I am using the engboot to do any data back up or restore tasks in TiBU then flashing the AP again to unroot. Data is maintained, but now I have to live with ads. I use adguard, by it feel like it hurts battery life. Will try and quantify that soon.
Being able to count on my phone to make a call and hold a charge is too important to me. Rooting the phone to set it up after a reset saves me time. Unfortunately, rooting with our current method is too prohibitive for daily use.

Same here.
I have a 930U that I use on Verizon. I use the 930V firmware because I like having visual Voicemail. I have rooted 3 different times and gone back to stock everytime. I suppose it because of the engineering kernel but root with the S7 is just not stable. The battery life sucks and you have to do so many things to fix the lag it has just become not worth it. Also the 2 latest updates from Verizon have been good on battery. I do like not having Verizon logos all over my phone.

Give stang5liter rom a whirl. Been on it since it was released and have no issues besides nearby devices not working for me.

Been using the same ROM for almost a week with xposed and everything is fine. I feel great without seeing the ads again. haha! BTW, I didn't try the nearby devices so no comment on that.
I have the G930V and am running APH1 with root no problems. The lag was horrendous but after changing the CPU governor to "interactive" on BOTH CPU's (little and BIG) it's been running smooth. I'll run like this for a bit... but stang5liter looks like it will be my next move.
Has anyone with ph1 tried flashing another rom such as stang5litre?

PH1 doesn't break root. You just can't downgrade to older firmware's or flash any U firmware's. PH1 is still completely rootable.
So you can't Odin flash back to a stock image if you get in trouble or want to unroot. I guess I'll stay on PG5 for now.
I'm not rooted now, but was able to disable system update notifications using
https://play.google.com/store/apps/details?id=com.hecorat.packagedisabler
By disabling:
System updates (com.samsung.sdm)
System updates (com.samsung.sdmviewer)
and securitylogagent

Thanks @FoxyDrew for clarifying that... and I agree.
I used the following GUIDE to root APH1 on my S7 Flat: http://forum.xda-developers.com/verizon-s7-edge/how-to/verizon-root-knox-t3410624
Im somewhat confused. Your saying you cant downgrade from ph1. Are you talking only with odin? Reason i ask is stang5litre rom is APE1. And as was stated a few posts up, this rom can be flashed on rooted APH1. Which would take you back to APE1. Therefor downgradable? Any help is appreciated.

Ph1 upgrades the boot image therefore you cannot Odin flash back to stock pe1 which is the older boot image.
You can still root and flash stang5litre which is the pe1 rom, but you still have the ph1 boot image.

You can still root and flash stang5litre which is the pe1 rom, but you still have the ph1 boot image. So if something goes wrong, you have no means of recovery back to stock since there is no ph1 stock Odin image.

The ph1 image is available at this link (http://updato.com/firmware-archive-select-model?record=78F84FCD811E11E69B2DFA163EE8F90B). I have flashed with these files and they work perfect.
Seems bootloader was uograded to version 3. So may be possible to flash between tmo and vzw and vice versa. Both now have v3 bootloader.

Downgrading 6.0.1 to 5.1.1

Hi if anyone can help- I'm on the Verizon Samsung Galaxy Note 4 after 2 Note 7's and a Note 3 before that on Biggin's so I've sorta been out of the root game. I want to downgrade from 6.0.1 to 5.1.1. I am downloading the full firmware for the Note 4 from further back in this thread (N910VVRU2CPA1) and am currently on (N910VVRU2CPG2).
From what I understand, I need to do a factory reset, then go to Odin and flash the firmware. I have Odin 3.10.7 and am downloading the N910VVRU2CPA1 as we speak. I see 'hsbadr' firmwares in his thread and the PIT file TRLTE_USA_VZW.pit which I'm not sure is compatable pit file for the specific 5.1.1 firmware or the necessary pit file is included in the full firmware and can anyone tell me if these are the right steps?are these the right steps Any information would be greatly appreciated,
Thanks

I bought the phone already with 6.0.1 on it and read that you cannot unlock/ root it with mm on it and can only be done after downgrading to 5.1.1 so I haven't done anything yet
I'm in the same boat...Coming from a n7. Bought a n4 on eBay...It's got 601. Want to root...Guess we need to downgrade....Is it possible?

Before you can start rooting, you'll need to be on 5.1.1 BPA1. If you're currently on 6.0.1, just download the BPA1 firmware from Sammobile, factory reset on 6.0.1, then flash BPA1 stock via Odin.

Hi thanks, I had called Samsung and talked to top tier tech support and was told that once the phone has been upgraded to 6.0.1., it cannot be downgraded. and that i need to search the rooting sites and try to find where someone has found a breach or workaround for unlocking the bootloader which will usually have a bounty but I dont know. top tier tech support has always been good. Do you think thats false it cannot be downgraded?

https://forum.xda-developers.com/no...mware-firmware-kernel-modem-recovery-t2942937
If I am downgrading to 5.1.1. which this phone was obviously on before, I don't know what this phone was on since it currently is on the PL1 build which are not one of the two 6.0.1. builds on this page. I don't even know if that matters.. Anyway, the two 5.1.1. builds are PA1 and OK3. Do you know where any other firmwares out there that might show my current one and the previous build that it came from?

Yeah they're out there but that thread hasn't been updated recently. Basically the order after pf3 is pg2, pj2, and then cpl1. The one you want, if your planning on rooting, is bpa1. Also, as far as your question in the op about the pit file, it should really only be used if absolutely necessary. It's in case your partitions have been corrupted for some reason and you need to repartition your device.
Edit- I was going to link to those other firmwares but they are buried in the thread that your already looking in. Either way they aren't necessary for you to unlock your bootloader, you can go straight from cpl1 to bpa1.

Hey thanks for confirming all this. So all I need to download and install is the bpa1 firmware via Oden with the AP button I think- I've got a few different versions of Oden on my pc. It's been a while since I've flashed firmware on a phone but I remember it was easy. So just save my pictures, any files, etc. on the sd card, remove it, then do a factory reset or when I put the setting into usb download mode, and flash the firmware this will automatically factory reset the phone? Also earlier today Verizon has been trying to push an software upgrade. After I unlock the bootloader and install twrp then flash a rom, do I need to somehow disable the update notice. I remember having to do that once with another phone.
What rom are you on? Thanks again for the Info-

Yeah that all sounds spot on. I would definitely do the factory reset before you start, but other than that your good. To block the updates, you can uninstall the SDM apps. There are 2 of those and you'll need root to remove them, but you can disable them without root with that debloater tool. The rom I'm currently using is kind of work in progress. I have a couple stock based roms in the dev section, one is stock_plus that has a stock feel with some mods added and the other is Modest Rom that is got some grace apps added and system ui mods. You can find them here and here if you want to check them out.

Custom kernels help a lot. The problem is it's kind of slim pickings for our specific model, but some of the international kernels work well too. Oscar kernel is made for the 910v so that's probably the most reliable but if your like me, I like to use a permissive kernel and Ram kernel is not a bad choice for that though it's not as feature rich.

I really dont know the difference... from what I remember a kernel is the layer between the software and the hardware- a key component of the os. I'm guessing the permissive ones can be used for different roms or firmware? You can probably tell I really don't that much about the root game. The last time I flashed a firmware was on my note 3 after I bricked it. Then rerooted and got on to biggins rom which was great ut I never understood or learned how to use xposed. Anyway, I downloaded Modest Rom, PJ2 _STOCK .tar and am downloading cpl1_tar but I know that once I flash bpa1 firmware which puts the phone back on 5.1.1. I see your roms are 6.0.1 roms, after I flash the bpa1, will the bootloader be unlocked? If so can I then just flash the cpla1_tar or is that not a full firmware? or use one of the two 6.0.1 firmwares from where I found the cpa1? Are the kernels different from 6.0.1 and 5.1.1 and where to find the downloads?? I appreciate the tips especially coming from a develpoer and i'm happy to make a donation- I'm not sure how?

Hey buddy, did you get it figured out? I broke my arm at work on Sunday and of course it's my right arm so I'm having some issues responding back on my note with one hand. I bet I've dropped this thing 20 times already.

Oh man that sucks- hopefully they gave you some good pain meds. Anyway, I havent taken th plunge yet- once I get on to 5.1.1 then twrp, I want to go on to 6.0.1 but am unsure as to what point the bootloader is unlocked or exactly what to do to upgrade to 6.0.1 once I crack the bl. I just dont want to go through the dreaded set up everything twice.

Bootloader upgrade questions

Hi,
I was reading the threads about upgrading / unlocking the bootloaders.
After spending almost half day rooting and rerooting, I have a few questions.
Right now I am on BPA1, rooted, stock. In order to install an Marshmallow ROM, it looks like I have to upgrade the bootloader, to minimum CPD1. Here it gets confusing. I already changed the CID to developer and the bootloader is unlocked. If I try to upgrade:
1. Can I flash just the bootloader (and eventually the modem) and not the entire stock firmware?
2. Will I lose root? If yes, I have to reroot, but the rooting tools are kind on unreliable, spent a lot of time already, no guarantee they will work again...In order to push the files for bootloader unlock, root is required. Is there a way to keep root? Flashing the stock firmware seems to lock the bootloader and eliminate root, so every time something needs to be upgraded, we have to go through the same process?
3. At this point, it looks that there are so many updates: CPD, CPF, CPG, CPJ, that I need a CPR if I have to repeat the process 4 times! Some roms don't require the latest update, but if it installed, will it work? E.g. the rom requires CPF and I upgrade to CPJ, what happens?
Thanks!

Right now I am on BPA1, rooted, stock. In order to install an Marshmallow ROM, it looks like I have to upgrade the bootloader, to minimum CPD1. Here it gets confusing. I already changed the CID to developer and the bootloader is unlocked. If I try to upgrade:
1. Can I flash just the bootloader (and eventually the modem) and not the entire stock firmware?
2. Will I lose root? If yes, I have to reroot, but the rooting tools are kind on unreliable, spent a lot of time already, no guarantee they will work again...In order to push the files for bootloader unlock, root is required. Is there a way to keep root? Flashing the stock firmware seems to lock the bootloader and eliminate root, so every time something needs to be upgraded, we have to go through the same process?
3. At this point, it looks that there are so many updates: CPD, CPF, CPG, CPJ, that I need a CPR if I have to repeat the process 4 times! Some roms don't require the latest update, but if it installed, will it work? E.g. the rom requires CPF and I upgrade to CPJ, what happens?
Thanks!

Yeah it definitely gets a little confusing, but I might be able to clear up a few of your questions. The bootloader you want to upgrade to is the cpd1 version, after that the only things that change when you upgrade to pf3, pg2, and pj1 are the kernels and modems. Right now I'm using the latest pj1 firmware and my bootloader has never changed from cpd1 and flashed between the different versions several times and for unlocking the bootloader on 6.0 you do have to repeat the process you did for lp, unfortunately.

OK, so what file do I need to download and flash? I have to unloack the CPD1 bootloader and reroot? Which app? Kingroot or Kingoroot?
Once this is updated, how can I upgrade the modems and kernels, can I flash them individually?
Thanks!

These are excellent questions that I'm sure a lot of members are thinking, but just haven't formally asked.
I have a Developer Device that I got directly from a Samsung 2 years ago. When hsbadr put out CM 14.1, I was still on Android 5.1.1. It seemed like a daunting task to do all that was required to get to CM 14.1, but I went ahead with it. I decided that it just made more sense to have my device CID changed to the one that everyone else was on, so I went through all the motions. Yes, the root thing was very touchy. But it really wasn't all that bad.
I'm now on bootloader CPD1, and just today upgraded the baseband by odin flashing the partial firmware for CPJ2 baseband.
Can't wait for hsbadr's next build!!!!
Ok, so in conclusion, which file needs to be flashed to upgrade to CPD1? Is it a stock tar, or the bootloader can be flashed just by itself? After flashing I'm gonna lose root again and have to start over before changing the CID?
You mentioned that you have a developer edition. I have one developer and one retail. My developer is still on an older Jasmine, but it needs to sent for repair. I'm trying to get the retail one done, so I can use it in the meantime. Then, the plan is to get the same thing done on the developer edition. I was hoping that would be easier, as the bootloader is unlocked, but apparently that's not the case.

Nobody can recommend the right file to flash?

I am also looking for advice on how to upgrade the bootloader. I am on BPA1 currently but everything I find keeps upgrading everything but the bootloader.
Thanks in advance for any help you can provide.

Note 4 - Android 6.0.1 - Downgrade? Or Fix? -- Neubie here

Hi, I've got this one Note 4 that's had loads of trouble presumably since the last security update.
Baseband Version: N910AUCS2EQD1
Android: 6.0.1
Have seen the instructions and all as to how to go about downgrading BUT one site I came across with the original stock firmware downloads outright state how:
""DO not ever try to downgrade from any newest Android 6.0.1 Marshmallow updates back to an older 6.0.1 build version""
'and so I'm lost. Should trying to then reinstall the same Baseband version atop what's already there a good first alternative? ...that is, just in case it was never upgraded properly in the first place? Or is that not even possible?
Is trying to downgrade at all a futile pursuit?
Would truly appreciate any suggestions, help, direction...heck, anything! Thanks in advance.
I downgraded from 6.0.1 epk5 to 5.1.1 with no problem.
Not sure about qd1.
As long as you have the odin firmware, I see no problem.
Can i downgrade note 4 n910a from marshmallow to lollilop,please help me i am in great trouble because marsmallow update is very bad with a lot of reboot issue ,battery drain.
Once you are on QD1 you will not be able to go back to anything lower than that firmware. The bootloader is now at the latest version and has blown one of those imaginary "e-fuses" so that you can not go back in time to any other vulnerable OS. I just tried today to go from EQD1 to EPK5 and It would not flash and would fail every time whilst using the latest Odin. So good luck on finding anything on getting you back to another firmware version but at this time I do not believe there is anything that will move you back to the firmware you want. If you do happen to find something or make your own exploit do tell @sanaullahkhan371 If you are on QD1 you are not going to be able to downgrade if you are on PK5 you can try the Odin downgrade method that will5 presumably used but if you are not in this firmware use case you are SOL.

Hi,
Can you please let me know how did you downgrade? Is it straight away flash to 5.1.1 or did you follow any steps?
I am also planning to downgrade. Anyways, I stopped using Note 4 after update to 6.0.1 as it was switching off every now and then due to update. Might as well make this phone usable to take photos and as a video player for my kid
Thanks

I just odin to this firmware N910AUCU2DOI2-5.1.1 It s available somewhere on this forum.
Read how to odin if you never used it. In this case you need to unzip the file and load AP, BL, CP and CSC files on odin and flash.
Was running 6.0.1 epk5 previously.

Thanks a lot buddy! :good:
My note 4 was also running on 6.0.1 EPK5. Found the 5.1.1 firmware and followed your instructions to downgrade. My phone came back to life and is usable now.:victory:
No more switching off abruptly! I wont update anymore since all the apps which I use are working fine with current version of Android.

Were you ever able to flash back to an older version from QD1? Others have said that the bootloader was not incremented in QD1.

I'm also on EQH1. I have never tried to downgrade. I was just curious if it was possible, in case a root method was discovered that only worked on older versions. But I've just learned to live without root. EQH1 works fine for me.
I had the infamous freeze/reboot/shutdown issue with 6.0.1 and I wasn't sure if that was the issue but I downgraded to 5.1 and have fewer issues now. The phone runs just fine, except it does not reboot. You have to do a soft reset every time. But with the Wakelock app, at least it runs.

N910VVRU2CQF2 Rootable and Bootloader unlockable?

I had this phone rooted and unlocked when it was 5.0.1.
my brother upgraded it to 6.0.1 N910VVRU2CQF2 by mistake.
Can I root and unlock the bootloader again?
Thank you

I personally have no clue, but from what I do know, when I upgraded from 5.1.1 to 6.0.1 or whatever it is/was, I had to do the rooting/unlocking process again. We all did. Have you even tried it? If so, are you getting any errors? I noticed that hsbadr's thread on stock ROMs isn't updated to this version, yet. You might want to wait around for someone to give you a more firm answer. I'm just giving you food for thought.
