[Xperia Z3 Compact Q&A, Help & Troubleshooting] dakuhonoo:
Hello, I want to root my new Xperia Z3 Compact just to uninstall the carrier's bloatware. It came with 23.1.A.1.28 (i exchanged it for a new galaxy alpha, it was bought at the beginning of June ).

Rooting status says : Bootloader unlock allowed : No.

I don't even want to try to unlock it. Is it possible to downgrade the firmware with locked bootloader?

Will i lose anything? If possible, I'd really like to have a complete guide on both downgrading, rooting and upgrading back.

Thanks.

[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] DreamingWolf:
Background - I took the OE1 update and faced the same issues with flashing that have been so widely discussed. In my attempts to revert I tried Odin, which failed every time, and restoring my most recent TWRP backups, which failed to boot. I was able to flash AOSP ROMs and assumed I'd be restricted to their use until a fix was found.

About the same time that the Noterized ROM and the latest emotion kernels were found to work, I was playing around with my older TWRP backups, one of which included every possible option including boot, modem, EFS, etc.

The first time I restored the entire back up and it wouldn't boot. Then I tried just restoring the modem and EFS, then flashing the Hybrid-X ROM and the latest emotion kernel figuring at least I'd have a working system. Strange thing was my baseband showed up as OB7 in settings.

I got excited and immediately made a backup in TWRP and tried to Odin the base OB7 ROM. It failed. So still using Odin I rerooted and installed TWRP again. Then restored my backup. Baseband still showed OB7.

So I decided to experiment and wiped my phone thoroughly (factory reset X3, format data X3, advanced everything but extsdcard X3, then flash Uberwipe.zip) and when TWRP had restarted I flashed the Echoerom TW ROM from mid march. No current kernels, no mods of any kind, just the base ROM. I walked away to finish a chore and 20 minutes later I returned to find, to my immense pleasure, that the setup screen was waiting for me.

So I can verify, at least for my phone, that if you have taken the OE1 update, but have a full OB7 backup (you backed up every option there is) in TWRP, it IS possible to restore the modem/radio firmware and flash any OB7 TW ROM you wish through TWRP!!!

Odin will still fail if you try to do more than root or install TWRP, but access to all OB7 ROMs is possible after the OE1 update has been taken.

Moral of the story for me - ALWAYS have at least one backup that contains everything in TWRP.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] superassassin:
Thanks for posting this, it gives me hope. I have two Note 4's I purchased used about a week ago (one white, one black)... I needed to get MSL for both so I downgraded through odin to 4.4.4 (worked on white, not on black). After researching a bit more on here I realized the non-working Note 4 probably has the OE1 update - so this would explain why it's in a boot loop & not working....

Unfortunately I did not take a full TWRP backup of either phone at the time...

Steps I have tried to get my non-working Note 4 working again:

-attempted multiple odin restores (no dice of course)

-installed TWRP via odin

-attempted OE1 nandroid restore that was uploaded by you (lol) @ xdaforums.com/showpost.php?p=60983327&postcount=55

-wiping 3x (everything but extSD) & install Noterzied rom via TWRP (I read this should work, but does not for me, black/blank screen on boot)

Why didn't the Noterized rom work for me?

Can I create/restore via TWRP using the working Note4 on the non-working Note4, or is that a bad idea?

Not quite sure exactly where to go from here... thanks!

UPDATE: I downloaded uberwipe, created a fresh 'full' nandroid backup of the white Note 4, then restored it to the black Note4 - now it is working!

Not overly familiar with nandroid backups... It would be interesting if one could be developed as a backup for those who took oe1 without making one?
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] l330n:
So if im completely stock OE1, theres no way to install the Hybrid X rom? Sorry, been reading all over the place and still confused about the whole ob7 vs oe1 issue
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] samep:
If you rooted while on OB7 and took a full nandroid, you could restore it then flash any OB7 ROM. But Odin would still be broken as far as stock tars are concerned.

Still an unknown if flashing baseband and bootloader from another individual's nandroid from OB7 is enough to accomplish same result. Maybe someone will post here when/if a working solution is found. I didn't confirm it but someone had posted baseband flash was a working solution on another note 4 forum.

If not, flashing Noterized Stable release 1 is the only TW custom ROM I'm aware of ATM. http://xdaforums.com/showthread.php?p=60506574

So, if I flashed Tx's stock, rooted, de-knoxed and de-itson rom, made a nandroid (minus EFS) it could be used to get OE1 folks back to OB7?
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] samep:
From what I understand, it may allow them to flash OB7 ROMs but Odin would still be broke as far as stock tars are concerned.

I believe there was a recent request for a nandroid sans the data and EFS partitions.

I don't think stock-ish was the request. Maybe Noterized or Hybrid X with latest Emotion kernel would be more likely to work?

[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] DreamingWolf:
Spent yesterday trashing and fixing my phone. I figured out that I didn't revert the baseband through a TWRP restore. (I have an OE1 base backup and I flashed the modem from that half a dozen times and it never changed to OE1 baseband). That means it must have been through one of the Odin flashes I did (that failed, but apparently AFTER writing the modem.bin)

Does anyone have an OE1 modem.bin? I can pull the boot.img from my TWRP backup, but the modem isn't stored in a bin format. I need one so I can test my theory.

Or, if there is a brave soul out there, I made an Odin flashable tar file of the OB7 modem and the r16 emotion kernel. I have flashed it multiple times on my phone with no issues. I know it changes the kernel because I have another file with the OB7 modem and the OB7 stock kernel that I was using as a base.

If anyone is willing to try the OB7modem/emotion kernel file and report back you can download it here.

As you can see from the following pic my bootloader is OE1 my baseband is OB7 and I'm running Hybrid-X 2.2

Fair warning though, I run Nova Launcher at 480dpi. If you are used to the default 640dpi, everything is going to appear tiny. You will need to edit the screen density line of the build.prop to change it.

[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] DreamingWolf:
I'll try and get it pushed to Android File Host later today.

And I had a thought as I was waking up this morning. When I first got my baseband reverted to OB7 I had been flashing a lot of failed tars through Odin and I ended up also rerooting and reinstalling TWRP. So I wonder if it would work better if, as a starting point, the modem/kernel got flashed, immediately followed by CF-AutoRoot, followed by TWRP, then go into TWRP to wipe and flash Hybrid-X.

[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] DreamingWolf:
That's what Galaxy Tools says about my phone.

OE1 bootloader

OB7 baseband

It's the baseband that ROMs need to flash, isn't it? The kernel has to match the radio not the bootloader.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Droid2drummer:
Actually right now what's blocking us I believe is in the bootloader! However, unless I find some space on my pc I can't find the reason why noterized boots but nothing else. I am curious to look inside and see. I can't. Lol. I can't extract anything right now. Unless I delete some stuff. I think the devs here have the tools they can pull their bases, and find the differences,...I don't even know anymore. I figured the modem would work. But yeah. The bootloader is at fault BUT BUT BUT then why will bob7 noterized work? Lmao.

[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] adrianr514:
Or better yet what it doesn't have. I feel maybe something was left out that isn't trying to overwrite either the modem or the baseband and allowing it to boot. And other roms might be trying to overwrite so no boot.

I'm sure it's not the kernel allowing it to boot because hybrid 2.3 is now also using emotion kernel but won't boot.

Did bobcat rom work on oe1
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] samep:
No. That is KitKat; no way back from OE1 OTA. If you're rooted, Noterized Stable 2 is an alternative.

If not rooted, I'd suggest waiting for next OTA and make sure a tar is available before rooting and flashing custom ROMs. The wait may not be much longer for Android 5.1.1 update.

If Samsung and Sprint fix the Odin stock tar issue, you may be able to go back to KitKat. But improved WiFi calling and HD Voice updates may have some wanting to stay current with lollipop.

Maybe it gets better. Looking forward to Android M, myself.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] buddyb0i:
Yeah im on noterized 2 i was just wondering and your right bobcat for sprint didnt get lollipop
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] beezar:
Still on kitkat here. How is WiFi calling improved on lollipop?
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] samep:
Where to begin? Here's my Sprint WiFi calling KitKat experience:

Outgoing voice or caller dropping during call

Call drop

Noisy outgoing or caller audio

Basically a crap-shoot for calls greater than 10 minutes or calls resulting in placed on hold. People would claim not to hear me and hang up after a hold session.

Plus, I couldn't talk at all to my wife on an iPhone 5 when on WiFi call; she always complained of not hearing me, latentency, drop outs, or distorted. Generally annoyed by my questions about the call quality and random checks for changes as I tried to improve it.

No problems with Lollipop; Sprint confirms there were major updates for lollipop WiFi calling. I've been on long calls since and talking to my wife on iPhone 5 and now iPhone 6; no issues.

I had updated firmware on the home router before lollipop update but even placing my phone on static IP and assigning it to the router DMZ, no such luck.

YMMV; I was thinking the Netgear router was just junk, it was getting interference from 2.4 Ghz penetration and got placed on 5 Ghz only to avoid quality issues. That helped with streaming HD video and audio but WiFi calling never improved on KitKat for me.

There's also speculation 5.1.1 update will further improve call quality on Sprint.

One complaint still: the outgoing Mic appears to be top only for loudspeaker mode. I often have to speak directly into top of phone to be heard. Maybe that's done to avoid speaker to Mic cross-talk? To add to that, cases seem to be talk sensitive; some are more likely to cause echo-effect more than others. I returned my first generation Spigen cases but newer ones are better than the Samsung Protective Case+ and original Verus Thor (respectfully; regarding call quality). I asked Verus to replace my old one but they didn't respond.

Edit: last paragraph rephrased and edited.
