Hi. I've posted this under the liniage thread, but I'm hoping more people will see it here since it's not a liniage specific problem, but rather something to do with my device or me. Any help would be greatly appreciated:
I am on the stock Samsung u3 Q firmware and I cannot get any custom Rom working, except for DR. Ketan which is based on the Samsung stock, but otherwise works great, root and all. My main purpose is to get to u1. I've tried liniage 17, 16, lightrom, crdroid and nemesis, all with the same result: after successfully flashing in TWRP, the phone restarts and does not boot. first it does another restart, then goes into download mode on some roms, and recovery in others. I'm sure I'm missing something, or doing something wrong, but I can swear I've followed all the instructions. Any guess to what that might be, or what I can try?
By u3 and u1 you mean bootloader versions?

Yes, the security on the boot-loader. Any since all official firmware check, that's not an option. But as long as I'm able to run a custom rom, I should be good, I think.
There is no roll back with bootloaders, I have never tried something of the sort, but it has been said over and over again that bootloaders can not be downgraded
Would that mean that any device with a higher than u1 bootloader will not work with custom roms? That doesn't sound right to me.. Perhaps I haven't asked my question well enough, so first, I'd like to figure out why custom non-samsung based roms all fail on boot.

You said you were on U3. If so, you cannot load ANY rom with a U1 bootloader. Period.

All firmwares, or ROMS, official or custom, have a bootloader version, newer ones have higher number version, you can not install anything with a lower bootloader number than the currently installed one, no matter if official or custom or whatever, this can not be circumvented in any way, so, if your current firmware has a bootloader 3, (U3) as you posted, you will be able to install roms (custom or official) with bootloader number 3 or higher, that's it, I hope you got it this time

Hey,
Still a bit of a noob to the whole rooting process and navigating XDA forums, so I'm having trouble finding the information *I think* I should be looking for. Basically, my phone's just begun crashing periodically, multiple times a day: anything from Camera, Process System, Touchwiz Home Launcher, or Samsung Apps have "stopped working" / "not responding" before. Of course, my phone's warranty has expired, but my contract isn't up so an AT&T Store wont re-image it for me :crying:
Even I can tell, at this point, that it's either my OS that's failing, or it's my hardware. I figured the easiest way to test this would be to put some stable CyanogenMod on it.
The information I'm looking for is: "is this possible?"
AT&T Samsung Galaxy Note 4
SM N910A UCU2DOI2
Currently @ 5.1.1
Thanks for reading,
~Vita.
No it is NOT possible to use any form of custom firmware or to root this device. It has a locked bootloader that has yet to be cracked open and the future of that happening os very bleak to non existant.
As for reimaging the device go to the note 4 at&t general section on the forum and read up on using odin and the 5.1.1 image posted there it will wipe the phone and format yhe system and data partitions and reinstall it like a new phone just like at&t would do or the manufacturer if you sent it to them.
Good luck
Thanks for the response.
Sorry for the dumb question, but isn't Odin able to flash any firmware onto a device? The "locked bootloader" means that only the stock OS may be reinstalled? Why is this...
Also, it seems unlock progress is being made on the N910V. Maybe hope?
Thanks for mentioning Odin, I'll try re-imaging the phone.

Well the problem is the kernel the bootloader prevents the devs from using an unsecure kernel (one not created and signed by at&t) on the phone if one is used the phone stops boot and says it is an unsecure non at&t kernel and to take thenphone to at&t store.
Odin can only write the firmware versiom that is currently on this phone in this case it is 5.1.1 if you flash any other note 4 versoin such as 4.2.2 it will brick.
Sm-910a flash example
Update ver Official at&t 5.1.1 / currently on phone 5.0.1 or 5.1.1 = good
Update ver (downgrade)oficcial at&t 4.2.2 / currently on phone 5.0.1 or 5.1.1 = brick not good or odin fail
Update from another carrier such as tmobile or verizon for 910t 910v 910g = fail (do not attempt)
Until oir boot loader is unlocked there is nothing we can do to mod or use custom firmware on this phone any attempt leads to a brick requiring using odin to re-flash the latest firmware (5.1.1 at this time) in order to make the phone functional again.

So from what I understand, I could use Odin to flash the 4 files which correspond to the specific AT&T 5.1.1 SM-901A version of my phone (which is exactly what I have) to re-image the device and make it functional again. The problem is, I cannot find these devices on sammobile D:
Could someone direct me to these files? Or are they not out because AT&T sucks? Or, what.

I think so, I don't know for sure but we've been able to Odin from various 5.0 Lollipop releases back to KitKat so should be fine.
downgrading from 5.1.1 or 5.0.1 to kitkat is possible but with many many problem but form 5.1.1 to 5.0.1 i don't know maybe phone will stuck or boot loop
thanks finitetime for your reply

I am sure that you are referring to a sim unlock. A sim unlock and unlocked bootloader are two completely different entities. To flash a custom rom you will need to have your bootloader unlocked, which is something that a few of us are currently working on. Until then, no custom roms can be flashed on the att variant Note 4s. Take care
the boot loader says Qualcom secure boot : disabled ?
in the boot loader screen ?

Sorry, was off the forum for the weekend. Spexwood was correct, that is sim unlock. Qualcom is for the sim IE network. Take care.
Root is possible btw
Root is possible if youre willing to dedicate 10-30 hours of repititive root fails
How?

How is root possible? What's the process ?
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.

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
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.

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.

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

By disabling:
System updates (com.samsung.sdm)
System updates (com.samsung.sdmviewer)

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.

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.
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,

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.

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.

Awesome, I'm going to check those out but I forgot the biggest question of all... how to get rid of the Galaxy lag- is there a rom or tweak where this can be fixed since recovery cache delete and cleaning tools dont really do much?
Thanks again-

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?
Thanks again!

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.
I assume OTA would break root, is there a certain way to do this other than flashing a custom Android 11 Rom? I'd prefer to be on stock Android 11 with root but not sure how to go about it

So, if it's rooted, you won't get an update, or rather you won't be able to apply it. So it won't 'break' root, it just won't happen.
Sure, just crossflash to the newer rom, it has no effect on root. Doing so doesn't affect root, it will stay exactly as it was prior to crossflashing.

Forgot you're using an at&t rom, and those kdz aren't available. So, choices, go to an 'open' rom, which should have much of the at&t functionality, but maybe not all. Or, re lock the boot loader, do the update ota, and then root it again.
Be careful though, to relock a boot loader the rom has to be completely stock, no mods whatsoever.
personally, I'd just go with one of the 'open' roms... and I'd never use at&t lol, but that's just me.

I'd suggest the USA version, it's the us open, should have all the functionality for all the carriers, minus the bloatware.
Except for one thing, some carriers, like at&t, have in the past, not sure if they still do, limit things like volte ability to just their phones / roms.
that, and because they don't make their kdz available, I would never use them.
