TWRP 4.4 build on 5.1.1 ROM? - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

UPDATE: So, I couldn't really wait, went ahead and flashed TWRP. It installed just fine, as long as you get into recovery immediately, TWRP sticks. I flashed SuperSU and rebooted and got into a boot loop, so had to flash the stock firmware again and everything is fine again. No idea why the bootloop, so if some expert knows, please share
-------------------------------------------------------------
So, T-Mobile/Samsung FINALLY delivered 5.1.1 on the P607T and it looks quite awesome so far. My device was rooted and had twrp, so I had to flash with odin and now have neither twrp nor root. While I know that its only a matter of time before the community updates the tools to make it easy for us to root, I wonder if somebody could tell me if its okay to flash the existing twrp_2.8.7.0_4.4 build on this new ROM?
I vaguely recall reading somewhere that with Lollipop, Android moved to a new FS, but suspect this only applies to the system and boot partitions? That flashing recovery should be fine, and worst case, twrp will not stick? But, just in case, it would be great to know if this is true from someone with more experience ... If yes, then I can try to flash twrp and see if SuperSU still works through ODIN.
Thanks!

I tried root/TWRP using the P605 NEE thread method and I get the bootloop. It takes the modified ROM but not the SuperSU. Anyone else get root on P607T 5.1.1 yet?

From what I gather so far, 5.1.1 is rootable, but a bit more complicated than other versions. There are instructions one can follow to 'manually' root (meaning no simple odin flash), but these have not been tested on the Note 10.1 firmware yet and so no guarantees. I am told its just a matter of somebody who knows picking it up and creating a flashable solution, but the device is old and the world has moved on to Android 6.0, so this is not very high priority and we may have to wait a bit more.
The manual instructions, I understand them enough to want to try, BUT am not a developer and am worried about bricking my device! If anybody is brave enough to try,

Seriously need some help. At the end of my patience with trying to update this thing

I'm really frustrated. I've been trying to update this Galaxy S3 for days now with no success. Currently I am running on Slimkat 7.0. It's sometimes slow and buggy and needs some updating.
For reference, this is the phone at its current state:
- Bootloader: i747ucalh9 (literally taken from the fail message when trying to update to any other bootloader)
- Modem/firmware (?): I747UCLH9
Here's what has happened, greatly summarized (note I'm using CM6.0.4.7 for all of these operations, and when I say "update", I mean "flash"):
- I tried updating to Slimkat 9 but received no signal. I gave up on it entirely for a while
- I tried installing various LP ROMs, including CM12.1.
- I had 12.1 running for a bit, but I had no connectivity. LTE, 3G,H+ nothing.
- I tried installing a newer modem (this thread. Finally at MJB, I could actually get connectivity in some of the newer ROMs (including Slimkat 9)... but it was very erratic. It would just randomly oscillate between LTE and 3G and H+. This also broke CM12.1 entirely.
- Again, the above problem was always present. Most of the LP ROMs would just bootloop me, though. The only one that worked was Cyanide L... which I didn't really like.
- I thought maybe the issue was the bootloader. My bootloader is still i747ucalh9. So I tried updating it to various bootloaders from here, but none of the updates will work. Literally, they give me error 6 or 7 and pretty much essentially tell me that I can't do it.
- So after repeating the cycle of "let me try to update this" several times and having the update fail on me, I'm still stuck at Slimkat 7 as the only thing that worked on LTE (note the past tense). Worse yet, I tried simply downgrading my modem to match my current bootloader version, but that made things worse than better. I am now stuck at 3G... which just recently went back to LTE. Talk about erratic.
- I also tried going full stock by flashing this: http://forum.xda-developers.com/showthread.php?t=2363882 But it expects 5 arguments for format, and got 3... or something. Failed hard.
So, I'm pretty much at the end of my rope here. I really might just go and grab a new phone at this point. I just really don't want to because this thing still works fine.... I guess I got unlucky and am at a version of the bootloader that is difficult to update from. I can't seem to go anywhere with this thing. Anyone have any ideas? Do I need to use a different recovery?
Thanks...
First and foremost, verify your bootloader. Install the Samsung phone info app, or in a terminal app or adb shell enter:
Code:
getprop ro.bootloader
If you're on any of the older bootloaders (the ones that do not end in MJB, NE4, or NJ1) there are two ways you can go (you probably will be given the age of your modem). If you're on any of the ones that end in MJB, NE4, or NJ1 you've got to be a lot more careful because downgrading them will hard brick your phone (Odin back to stock is not an option anymore).
Option 1: If you're on the older bootloaders, you can go to sammobile.com, grab the 4.1.1 firmware from there and flash it with Odin. Do not do this if your bootloader ends in MJB, NE4, or NJ1 (can't stress that enough). This will reset your phone completely to stock. You should now start getting OTA updates. They will be incremental updates, you'll have to take at least three or four to get up to date on bootloader and modem and they're big downloads. They will come every 24 hours, but you can cheat that by setting your system time forward 1 day to make them a little more rapid fire. This is a nice, safe way to get your firmware current. Once you're up to NJ1 firmware you can use Odin to flash a custom recovery and get back to custom ROMs; I'd recommend TWRP 2.8.6 if you're going to be flashing newer ROMs as CWM and Philz aren't as up to date and sometimes give problems with newer ROMs.
Option 2: I'm pretty sure your version of CWM is a big part of your problem. If you're going to be flashing lollipop you ought to update your recovery to TWRP 2.8.6; easiest way to get it is just use the Flashify app. I'd get that recovery up to date before messing with bootloaders too. Next get your firmware up to date. If your bootloader version is before MJB, then you have to start with MJB. Then update to NE4. Then update to NJ1. It has to be done incrementally, and the bootloader and modem must match on the newer firmwares, or you'll hard brick. This thread has recovery flashable MJB and NE4 bootloaders/modems; the bootloader and modem are packaged together in the same zip so you can't get out of sync. This thread has recovery flashable NJ1 bootloader/modem. This will get your firmware all up to date, and data should start behaving on newer kitkat and lollipop ROMs. This route is a lot more risky than the OTA route described above because of all the manual steps you have to take, but you could get it done quite a bit faster if you're confident in your abilities. Just read those linked threads very, very carefully and make certain you understand.
Good luck.

Thanks a lot for the help! I actually did/tried a majority of this an hour or two before you posted that, except the latest firmware update link you supplied. I knew it existed and I had seen that thread before, but I couldn't dig up the link again before I had to go to work. Thing is I kind of wanted to avoid Odin for some reason but I finally gave up and used it. And yeah I already knew my bootloader version. The phone told me when it failed to update the bootloader lol.
Here's what happened thus far:
- I used Odin to flash the sammobile 4.1.1. The flashing worked just fine, but booting into it did not. It hung on the Samsung logo. So, OTA updates were out the window.
- I have no idea why, so I just used Odin to flash TWRP onto it afterwards (from here)
- I tried one of the ROMS. Data still didn't work.
- I used the thread you linked to update to MJB bootloader and whatnot. The update went fine.
- Tried another few ROMs. Data worked, but LTE was still erratic.
- Updated to NE4 and then grabbed the deoxed stock ROM.
- The deoxed stock rom failed to boot (stuck at ATT globe logo). For some reason my phone can't use stock ROMs.
- So again used Odin to put TWRP onto the phone
- Installed various LP ROMS. Again the data was erratic and plus the battery life was horrid.
- Tried getting the ktoonsez kernel. My service was murdered.
- Gave up on LP. Tried Slim 9.0. Erratic data.
- Tried Liquidsmooth 4.4.4 instead.
Currently that's kind of where I'm at. The LTE data works fine (takes a bit to get up and running after reboot though) and thus far everything is okay (though that can quickly change considering I haven't done much of anything), so I don't even know if I want to mess with it anymore. It looks like this specific ROM includes a custom kernel. So I'm guessing it's an incompatibility between the kernel and the firmware version on the other ROMs. It seems like most of the LP roms have horrible battery life (back of my phone feels like a furnace on them), so I'm not even sure if I want to do that last firmware update to use them.
It'd be kind of nice to use the OTA but apparently my ability to go stock in any form or fashion is just totally borked.
Thanks for the post though, that's pretty gold. I'm sure someone in a situation like me where they have a super old firmware will find this thread of some use as it has actual instructions and links to what you need to do to get up and running. Before you posted that, I had to go digging around pretty much everywhere figuring out what and where was going wrong.
Glad you've got it mostly working.
You might have been able to get that stock ROM to boot if you had booted into the stock recovery and run a full wipe. Touchwiz ROMs can be tough to get running after being on AOSP. As a general progression try to format internal storage with TWRP (the wipe where you have to type "yes" to confirm), if that doesn't work try a wipe with Philz, and if that doesn't work nothing, not even Odin, is effective as a wipe in the stock recovery.
Thanks for typing all this out I believe it will help me put cm12.1 official on a friends phone.
Are these the steps?
1) verify latest software
2) twrp via Odin
Alt 2) root via apk then use rashr or similar to flash twrp
3)wipe
4)In twrp install official d2att from cm website
5) install current gapps
6) profit
I'm not new to this at all but I've never even touched an att gs3 and I know most devices have their quirks and I don't want to brick.
Also does towel root work on this? I don't mind Odin but I can do this on the fly I think if I can attain root.

Yep. You've got it. If you're on the latest and greatest firmware I think the towelroot exploit has been patched, unless geohot has retaken the lead in that arms race.
Easiest way to root on this phone since the bootloaders are unlocked is to just use Odin to flash a custom recovery then use the custom recovery to flash SuperSU. There's just a little trick to it. Store SuperSU.zip somewhere on your phone before flashing the custom recovery. Uncheck everything but f.reset time when you use Odin; don't let it auto reboot. Upon success pull battery. Replace battery and boot straight into recovery with vol up + home + power. If you mess up and boot into unrooted stock ROM with a custom recovery it will get overwritten with a stock recovery and you'll have to Odin custom recovery back onto it and try again.
I would do this to root your stock ROM just to execute this command in a terminal app or adb shell before any more serious flashing:
Code:
su
reboot nvbackup
That fixes a derp and gives you a working efs backup on a few backup partitions built into your phone instead of a blank one. Highly recommended before doing any ROM flashing. This will just look like a pretty normal reboot. You might see a quick flash of tiny blue text if you're watching for it.
Then you're ready to make a nandroid backup (just in case), wipe, and flash away. Take a look at LiquidSmooth if you're looking for a good lollipop ROM.
Nice... So the recovery partition gets rewritten every boot up until a custom ROM is installed and the efs can disappear... This is why you always ask questions.
Thanks for the suggestion on the ROM but I think I'll stick to official cm12.1 it's not my phone and that should be a nice readily updatable bland flavor of lollipop.

At the Android 4.3 update it was noticed that flashing a custom recovery would be overwritten by the stock recovery on the initial reboot unless following the method Jason described. Another solution was to delete two lib or .so files. On devices still on stock recovery, stock recovery does not overwrite itself.
There is a blank EFS partition on the device intended for a backup. The nvbackup command populates that partition with an image which will rebuild your EFS if it is lost during a modem update or ROM flash. The loss of EFS does happen. I believe wanam, of the xposed module fame, created an EFS backup tool for Samsung devices. I don't believe he updates it any longer because he rolled the functionality into a partition backup tool, the later is in the PlayStore listed under a different creator name, yet it's still him.
So I'm finally going to take the plunge, and update my boot loader/modem.. I never messed with it because all the Roms I used always worked.. I want to try lollipop, but due to old bootloader my phone won't boot with those Roms..
I'm on UCDLK3 bootloader/modem.. I know I have to upgrade to MJB, NE4, then NJ1 in that order in increments..
So my question: can I upgrade from LK3 straight to MJB with out any problems?? Or is there something I need to flash before I can get to MJB?? I think I can go straight to MJB, but better safe then sorry..
I know downgrading after upgrade most likely will brick.. Any information is appreciated... Oh, its an ATT I747..

Since you are on LK3 you may want to considr applying the free sim/carrier unlock method before upgrading; that is if you are on stock LK3 and you have not previously carrier unlocked your device.
There was an OTA release for the MG2 stock ROM, I believe that was 4.1.2. You may want to go to that before MJB. Did you make the nvbackup suggested by Jason?
Why would I do a carrier unlock, if I'm not switching carriers?? And if I do it, will I be able to use the same carrier?? Just seems like a waisted step for me.. But idk..
Jason's first post, option 2 is how I was planing to update.. And no, I haven't done the nvbackup yet.. How would I apply that backup if things go wrong? Not really sure what a nvbackup is..
Any information is appreciated..

There is a command to manually trigger the restore routine. I think it's
Code:
reboot nvrestore
but don't hold me to that. I'd never execute that command except if in dire need. The problem with this phone is there is an automatic routine that can be triggered in the event of a bad flash that will overwrite your nvram with the backup, even if the backup is blank. I don't think the backup stores anything modem specific, but I've never been able to confirm that. So I've always done it again after updating modems (only had to once).
Having the phone sim unlocked can be nice if you plan on traveling internationally. Otherwise, potential future carrier hopping or added resale value are the only reasons to do it.

If you will never be switching carriers, nor ever sell/give/trade the phone to someone who will switch, then it is an unecessary step to do the carrier unlock.
I see Jason beat me to answering both of your questions.

Need advice n7105 strange knox bootloop with every rom but 4.1.2 stock after cm10.1

Hello,
I'm a noob but usually try to fix this kind of issues on my own, looking at the boards, following tutorials, learning, but this time I think I'm not able to find a solution on my own so I'm asking for advice here.
Some time ago I installed cyanogenmod 10.1 on my Note 2 LTE and was happy with it for some month, than last week I tried to upgrade to cm12.1 It worked but there where some issues and bugs, mainly I wasn't able to swap internal/external sd cards.
So I decided to go back to latest available stock rom 4.4.2 from sammobile.
Here is where the problem starts. The stock 4.4.2 resulter in a bootloop, tried cache/dalvik/factory reset, flash again, whipe again.. nothing.
The phone is not able to get past the white label "Samsung Note 2 gt-n7105" screen. It goes black than the white label again and again.
It doesn't even get to the Samsung animated logo.
Ok bottloop, no problem, try to flash again something else.
I tried different Custom roms, different kernels, different flashing methods. I can flash anything with no problem but every time a get a bootloop.
During the various attempts knox fired, but I don't care. I don't know if this could be the cause.
Actually the only firmware that works is the original oldest STOCK 4.1.2, every other stock firmware past that or any custom rom is bootlooping the same way. To fix I only can reinstall stock 4.1.2 with odin.
I really need any advice or hint.
At the moment my goal is to get at least to stock 4.3 but I cant.........
Thanks!
When you first bought your phone, did it come with Knox?

nope it doesn't existed before, but now I can see it when I boot in download mode "knox warranty void:1"
Try to get the latest firmware available via kies ,that worked for me
http://forum.xda-developers.com/showthread.php?t=2088809/[URL]
From what you've described, I think the Stock ROM 4.4.2 from Sammobile contained a bootloader update. So when you flashed this ROM, it updated your bootloader from the non-Knox version to the Knox version.
I am very unfamiliar with the technical details of Knox, but I think the new Knox bootloader is causing your bootloop problem.
However, I don't know why 4.1.2 works when everything else doesn't work!
Can you check the Stock ROM 4.4.2, and see whether it really contains a bootloader update?

Since a boot.img is present, it means that it would flash your boot partition. So now we know for sure that when you attempted to flash the Stock ROM 4.4.2, your bootloader was changed to the Knox version.
So the lesson here is: before you flash anything via ODIN, always check to see if there is a bootloader update. Usually you don't want to be changing the bootloader on your phone.
***
So now there are 2 possible ways to reach your goal:
1) Keep your new bootloader and see whether you can get Stock 4.3 or Stock 4.4.2 running on your phone
2) Try to restore your old bootloader
As I said earlier, I'm not familiar with the technical details of Knox, so I'm not sure how to get Stock 4.3 or Stock 4.4.2 running on your phone when your Knox indicator is already 0x1. You need someone else to help you.
And you can only restore your old bootloader if you happen to have made a copy of your boot partition before you flashed the Stock ROM 4.4.2. Even if you did have a copy of your original boot partition, I'm not confident with helping you to restore your old bootloader. You need someone else to help you in this case too.
Conclusion: I don't think I can help you to solve your problem I'm sorry. Hopefully someone else who is more of a pro than me will come along to help you out.
Good luck!

Help new to this!

Hi guys and girls i am from the uk (england) and got my g4 about 4 months ago.
Fed up of lg's stock rom and how its very laggy and irritating to use now.
I have been looking everywhere about rooting the phone and installing custom roms to make it much better and more enjoyable to use.
But i am stuck i dont know whats the best way of rooting this phone i have tried booting it into stock recovery mode but it just dont work.
so can you guys please point me to a right good method of rooting and installing custom roms please?
Currently using android 5.1 on lg stock rom
Many thanks!
Take it that is a no haha
Well every phone has a different model number so I can be hard I soft bricked my phone were system ui stopped finally got bliss pop running I would go for cyanamod 12 or something

Have you unlocked your bootloader ?
No not too sure how to do that. Any good threads you guys reccomend.
Many thanks
So I know this is scary for you and because it is something new, therefore be sure that you want to live with the responsability if something goes wrong.
Now, the next forum thread tells you how to flash an already rooted image BUT, and this is very important, this works only if you have the version 10c installed (Check in About Phone>Software Version)
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
If you have the latest version of the software (20a) the best thing is to unlock your bootloader, void your warranty in the process, and flash a custom recovery. After that, you just need to flash the SuperSu zip file and you will have root.
To flash custom ROMs, just access recovery and flash the zip file of your ROM.
I'm using the unofficial CM13.0 and works very good for me, but I do miss the official camera app.
Thankyou very much for your advice okarr. Will look into this

Re-Flash Stock Rom on Verizon Note 4

So I followed a tutorial to unlock bootloader and root the Note 4 from Verizon (SM-N910V). First off I am gong to say that it was definitely challenging and time consuming. Mainly due to the inconsistencies in the tutorials. You got a few that claim it's unstable or that something wasn't mentioned or left out... Which is true. I not only encountered the lags and freezing, but also the "reboot cycle", that occured after the first round of unlocking bootloader. Now I am not trying to claim that I am better or that the authors are dumb, because as difficult as this "hobby", everyone has their own an unique style...
I was able to unlock bootloader and flash TWRP recovery, but was unable to flash any CF-AutoRoot, SuperUser, or any custom Rom. Along with that any "Stock" firmware I downloaded and tried to flash via ODIN or through TWRP was unsuccessful. Thankfully to persistence and a lot of research I was able to find a workable set of Firmware files on none other than an XDA_Forum.
http://forum.xda-developers.com/not...mware-firmware-kernel-modem-recovery-t2942937
The above link contains the necessary files required for any unfortunates that may occur while unlocking/rooting note 4. I used ODIN to flash files in this order. Recovery image, kernel image, and then Firmware image... I did download Modem file but was not needed as the Firmware image already contained it. NONE!!! I repeat... NONE of this was done through TWRP, once you flash the recovery image TWRP recovery is over-written and the familiar Android Factory Recovery System is now in place. Also I would like to note that I onriginally started with 5.1.1, the image/tar files I flashed are 6.0.1. I know for a fact that just like any upgrade, while you do have some bugs and fixes... it is doable and actually lesser of a headache than one might guess.
Ayways I hope that the information I have provided was helpful and beneficial to SOMEONE out there in the world... GOOD LUCK EVERYONE!!!

Can you go from retail stock 6.0 with locked bootloader to 5.1.1?

I'm... asking for a friend....
But seriously, I tried following the instructions on the "[Guide] Step by Step from Stock N910V 6.0.1 to hsbadr's CyanogenMod 13.0 " thread, intending to bypass them when I got to the point of being able to jump over to the newer roms, and all I got was a boot loop when I tried flashing in 5.1.1. Is it because I'm on a retail 910v or was it a user error kinda thing? I tried multiple times and couldn't get it to boot after the flash, ended up flashing 6.0.1 back just to get my phone back.
I'm also ready to free the bootloader and root this thing. It seems emotion OS is the most popular and up to date now, correct?
I have the CPL1 update from Verizon( Dec patch). I know there are a bunch of threads with how tos, but it's unclear how outdated they are and whether it works with these latest versions. If someone can confirm the best way to go from cp1 to emotion.. Let me know.
Also.. I saw a while ago a guide on how to go to developer edition. Why isn't that front and center anymore? Isn't Dev edition completely unlocked... Why wouldn't I want to convert to dev edition before dealing with any rom changes? If someone can give some clarification I'd appreciate it.
Great news, I went for the plunge and succeeded. Confirmed -> stock and latest version software as of Jan 20 2017 (CPL1) can be downgraded to 5.1.1, rooted, TWRPed, and blah blah. I used the same guide you mentioned at top (hsbadr's CM13 guide), except i stopped at step 52 and continued to install emotion OS instead. Highly recommend it.
I'm on EmotionOS now. Wow, it was really worth it. So smooth compared to touchwiz 6.0.1. Haven't found a bug yet, but even if i do, i won't care.
I'm not sure what you mean "when i got to the point of installing newer roms". If you got to that point, why were you trying to flash 5.1.1 again?
How did you root it? I flashed mine back to 5.1.1, but I'm not having any luck rooting.

Follow the guide. You are going to go through a complicated process using the king root apk. I think the guide makes you use king root 3 times total to accomplish various parts of the process. King root loads up and spins for a few minutes, eventually succeeds, then you gotta punch in some things to command line using adb. I believe this is rooting your phone a few times.
Eventually you end up with twrp bootloader and jasmine Rom and everything just sticks.
So far.. The only annoying thing with emotion is that I lost volte and video calling. Maybe they'll bring it in one day.
