Mismatching build numbers when flashing Stagefright update

Hey guys,
I have an unlocked & rooted Nexus 6 (T-Mo, I believe) that I'm using for Google Fi. I'm currently on the 5.1.1 update that I got pre-root, when Project Fi pushed it to me. My build number (in About phone) is LYZ28E .
Today I was attempting to flash the official Stagefright update via TWRP, however it keeps failing with the following message:
Code:
Package expects build fingerprint of google/shamu/shamu:5.1.1/LYZ28E/1914015 : user/release-keys;
This device has Android/aosp_shamu/shamu: 5.0/LRX21M/dees_troy11191312 : userdebug/test-keys
Again, my ROM is the stock OTA that Google pushed me. I'm not running anything custom aside from TWRP. Any clue why the installer is showing my device as 5.0/LRX21M, when it's actually 5.1.1/LYZ28E?
Thanks in advance!

Can't flash the OTA in TWRP. Have to be completely stock. It is picking up the TWRP recovery build that does not match stock recovery. TWRP is built from AOSP source and dees_troy is one of the devs.

Oh, I thought you could flash it as long as you downloaded and flashed it manually via recovery, instead of letting the OTA do it's thing automatically. Bummer!
There's no way to remove the recovery without doing a full re-flash either, right? It certainly seems like an exploit worthy of my time to patch, but I was trying to avoid the data loss :/

You can fastboot flash the corresponding factory images. Skip the userdata data image and will will not wipe data. OTA's are worthless if gonna run root and recovery. Someone may make a TWRP flashable. Would have to search for it.

Awesome, I'll dig around and figure out how to skip certain images while flashing and give that a try (I've never had to do that before). I'm pretty comfortable in the terminal though, so I'm not too worried. Thanks for your help, @prdog1

If you're running root, fastboot flash the system.img only. If you don't run a custom kernel, you probably should also fastboot flash the boot.img too.
Keep supersu on your sdcard and after flashing system DO NOT boot the rom. Boot straight into TWRP and flash supersu
If you boot rom install-recovery.sh will install stock recovery on first boot. .flashing super su amended this script so that won't happen.
You can also flash the radio.img. Your choice.

For OTA's the device needs to be unrooted and complete stock. Including 'recovery'. So flashing with TWRP-recovery will not work.
An alternative is to flash only the new system.img with fastboot.

FWIW, recovery flashable updates are here:

I'm having the exact same issue, but theirs gotta be a way around it, not sure how it does it but if I use the sideload option in NRT then it somehow boots STOCK recovery to flash the OTA, problem then for me is I loose connectivity when that happens. I retain sideload ADB connectivity when I try in Linux, but can't get the phone into stock recovery that way. If I can't get it in by the weekend guess I gotta fully return the phone to stock to get that update in. Hopefully somebody figures it out.

Booting to a stock recovery is easy.
"fastboot boot recovery.img"
Then you can adb sideload, as long as your rom is entirely stock and never rooted.
That said, fastboot flashing the system.img would probably be quicker.

You can flash the OTA all day anyway you want but if you are not stock it won't take. Only other way is one of the flashable TWRP versions that were linked to. And right now looks like that thread is down for update.

If I am running everything stock apart from the recovery (using TWRP), with an unlocked bootloader and the device is not rooted, can I simply flash the stock recovery.img without losing any of my data? Is it really that simple? Do I have to use a particular recovery.img?
All I want to do is restore the stock recovery so I can OTA the stagefright update. TWRP is preventing me from doing so at the moment, but I don't want to lose all my data.

Because of this, I did the update twice; different methods, to see of there are possible differences.
Differences between official OTA and flashing the new system.img only.
Update 1: Flashing only the new system image (1,7 Gb) with fastboot.
Update 2: Return to stock LMY47Z and install official OTA (24,2 Mb)
Both updates have the same results. Data and apps were kept but there were changes:
a. Changes in build.prop gone (DPI, Wifi interval);
b. Standard icons because the DPI value 384 was changed to 560;
c. BGN-launcher replaced. Google Now launcher became white again;
d. Root gone (SuperSu and Busybox);
(Update 2. Of course returning to stock, replaces the custom kernel).
After rerooting the N6 the following actions were needed after both update methods:
- edit the file: system/build.prop to change the dpi and wifi interval;
- reflash/reinstall: BGN-Launcher, SuperSU and Busybox;
- uninstall updates of the Google app to get BGN-launcher working;
- replacing icons from drawer to start screen.
So when you have made changes to the system, like DPI settings, an update will leave your data alone, but not the settings.

Yes, that is all you have to do: flash the stock recovery corresponding to the Android build you are currently using. You will not lose any data. Remember, data is stored on the userdata partition, so as long as you don't flash that image, all your data will be left intact.

Thanks, I flashed the LYZ28E recovery and all seemed well. However, I then went to install the OTA, and it ended up giving me the error, with the Android on it's back and the exclamation mark. Rebooted the phone and apparently "Your system is up to date".

The OTA doesn't check the recovery version, since it replaces recovery on first boot anyway. Only matters that its stock.
That said, the only reason not to flash the rightbversiin is if the download link.is down or you have a local copy of a different version anyway.

The exclamation mark isn't an error. That's the stock recovery splash screen. You have to press vol up + power at that screen to get to the menu
How are you trying to flash the OTA?
By unrooted, lets be clear. The rom must never have been rooted. Unrooting a rom won't work

You are right, the OTA doesn't check the version of the recovery. However, I can tell you for a fact that on older Nexus devices, using a recovery from a different version of Android would not allow an update to flash. (It is possible this has changed since then though.) I remember very clearly, helping many users troubleshoot (particularly given that the only available toolkit at the time would flash only one generic stock recovery, and not a specific version), and it was confirmed that the errors users were having were due to using a wrong version of the stock recovery, so the recovery version did indeed matter (at least on the Galaxy Nexus it did).

I press install update now, let the phone reboot and I get the installation screen with the progress bar. It sits at about 10% filled for about 10 seconds then I get the picture of the android laying on it's back with a red triangle and an exclamation mark. Underneath that it just says "Error!".

I have never rooted the phone. I updated the phone manually a while back and long story short, I flashed TWRP recovery instead of the stock recovery as I intended to. I just want to revert everything back to stock (which it should be now that I have replaced TWRP with stock recovery)

If you're.familiar with fastboot already, why not just download the full factory image and flash system, boot, bootloader, radio and recovery images?

Because you modified the system, it therefore doesn't match the expectations of the update, so it is protecting itself from corruption by not installing.
You need to install your updates from here instead;

Will he be able to re-root with this, given that others have experienced endless boot-loop when trying to root the stock image?

Yes, he can re-root after installing the full image. I have done so many times and never ran into a boot-loop from doing so. Just make sure to not flash userdata if he wants to keep his programs and settings.

I just did the update on my phone. I had been running 6 with root and unencrypted with TWRP recovery. What I did was flash the new radio and the system img from fastboot. Rebooted to recovery and reflashed my no encrypt kernel and SU package, wiped delvik and cache. Rebooted and was back up and running. I had to redo my build prop edit for lcd density and reapply the host files for adaway, but other than that every thing is as it was.

Great news. I wouldn't have thought that the case, given the root=bootloop situation with MM and the factory image.

Nice method. Allow me to add a suggestion for users using rro.layers.
Besides a backup in local storage of the no encrypt kernel and SuperSU, also make a copy of system/vendor/layers. This directory is wiped.

Magisk 16.4 with Pixel XL and OTA

Hi,
I am trying to install an OTA using Magisk and the method johnw has outlined. (start Magisk, uninstall and replacing the modded image/boot with the stock ones, then install the OTA, before it asks for a reboot and you reboot - install Magisk on the other boot slot.) this works up to the point where it reboots the phone - then it gets caught in a bootloop for about five times, and then a message appears that it couldn't install the OTA.
Has anyone been able to install the OTA using the outline method?

Basically same Problem here with the non-XL Pixel 2. However after the I think 5 times boot loop I ended up in the Google Logo screen with the Progress bar. However after over 50 minutes it wasn't gone. Hard reset didn't help - stuck again at the same Situation. Will now reflash the phone.
Would be also interested in Feedback from others on how to install the OTA successfully.

I have run into similar issues in the past. I wasn't sure if I was not getting the sequence of steps correct or not. In the end, I decided that the more straightforward and easiest method for me was just to flash the full factory update (removing the -w to preserve my data). Once upgraded to the latest release successfully, I just fastboot boot TWRP (don't install TWRP), then flash Magisk zip from there. This has worked for me the last several updates with no issues and the entire process takes less than 30 minutes. Perhaps not as elegant as the method recommended in this forum, but less moving parts and steps that can go wrong in my experience.
Good luck!

Thanks for your feedback.
Here's another way that I just tested successfully:
E.g. for updating from April to May:
- Still being on April patch Level, patch boot.img from May using MagiskManager, transfer to Computer
- Boot into Bootloader. Flash stock boot Image from April
- Boot into the stock recovery and install the OTA, e.g. using adb sideload
- After the OTA is installed, select to boot into the Bootloader again
- In the Bootloader Flash the patched boot.img from May that was created in the first step
- Reboot phone and enjoy the May update
@sb1893: I think your way is more comfortable though as one doesn't need to prepare a boot Image file.

@srynoname and @sb1893, thanks for the workarounds. I am doing what srynoname suggested, and while it works without any hiccups, I was really really hoping to be able to install either the OTA or a full factory image (without wiping the data) but with preserving magisks and root *without* having to connect my phone to a computer
So if you have any other ideas...
And to be honest... I am more than surprised that we're the only ones struggling with the update process.

@topjohnwu
Do you habe any hints about what we're doing wrong?

[Q][HELP] OP3T Soft bricked after installing TWRP Recovery

Today, after i installed the latest OOS 5.0.1 with Android O 8.0, i decided to root my device.
After successfully unlocking the bootloader, i flashed the TWRP Recovery and flashed the SuperSU zip, i was stuck on the 1+ Boot logo. I tried fixing the contents through advanced options of TWRP recovery and still no luck. I also tried wiping my cache, data, dalvik etc...
So far i tried:
Installed stock recovery via fastboot, then adb sideload. My device was recognized when typing ADB Devices but when i tried to adb sideload ota.zip i got the cannot read *...zip* error. Then i tried everything i could find, my devices are installed correctly, i also tried the Large Address Awarness program and still no luck.
Then i flashed TWRP again through fastboot and try to do the same through TWRP's sideload. Still no luck
Then i tried to adb push the ota.zip so i can install it manually through TWRP recovery.. still no luck
I ran out of ideas.... What can i do?
Thanks in advance

First of all, why didn't you make a TWRP backup of the stock ROM before trying to root? This is best practice before trying any mods (root, flashing ROMs) for reasons which are probably now obvious. I'm always surprised at how many folks skip this step.
Maybe you planned ahead of time to use the stock recovery image, if you had to. But since it wasn't on the phone when you need it, you're running into the problem of getting it on there now.

Honestly, I would recommend Magisk for root, over SuperSU. I've seen a number of folks have problems with recent version SuperSU on this device. And Magisk has a lot of really cool, useful features. I'm normally not one to recommend one method over another. Especially since SuperSU was so tried and true for so long. But at this point, I see no benefit of using SuperSU, but many benefits to Magisk. And seemingly less problems rooting with Magisk. My recommendation would be current version Magisk, which is v16.0.

First of all, make sure you are using the "full" update zip (which will be >1 GB) and not the partial OTA "patch". You can get the full zip from here (Post #2): https://forum.xda-developers.com/oneplus-3t/how-to/official-oxygenos-5-0-1-android-8-0-t3728119
Since you have TWRP installed, boot into TWRP. You should be able to see your internal storage on your computer, just like it's a thumb drive. Just drag/copy and drop the full OTA zip onto the phone's internal storage. Then just flash the zip in TWRP.
The internal storage should be selected to "Mount" in TWRP by default. But if you can't see internal storage on your computer, make sure it's selected in the TWRP "Mount" section.

You can verify by booting to TWRP. It says version number on the splash screen.

The internal storage should be selected to "Mount" in TWRP by default. But if you can't see internal storage on your computer, make sure it's selected in the TWRP "Mount" section.

I did make a nandroid backup from TWRP i just didnt restore it because i thought it was TWRP’s issue due to dm-variety... my bad but whatever
Yeah i have read about Magisk i just didnt investigate enough to know exactly what it is was so i thought it would be better to go for SuperSU because thats what i used on every android device i has... my bad aswell here
About the full update zip.. i’ll try that because i think i was trying to sidelod the ota patch which was 1.6gb...(but still, is the “cannot read xxx.zip” related with what zip file do i sideload? Whatever ill try it when i get home
And also i have already tried the mount feature of twrp recovery but my device just wouldnt show up on my computer.... I will try again later when i have the time and i will contact you if i need any help(if thats ok ofcourse) ...thanks in advance

TWRP and root shouldn't normally trip DM-verity (make the phone not boot).
I don't think it will hurt anything at this point to restore the backup you made. You're already trying to flash stock recovery, anyway (which is not that different).
If the restore is successful (phone boots to OS), then just flash Magisk and be done with it!

I wouldn't say it's "your bad". Magisk is just a suggestion or recommendation. Some folks have had success with SuperSU. But also seems like a lot more folks than usual, having problems (like no boot) with SuperSU than I'm used to seeing. And as I mentioned, I don't see any benefit of SuperSU (over Magisk) at this point. I was slow to change as well. But after trying Magisk, there has been no going back for me since. So therefore, the suggestion.
You didn't mention what version SuperSU, but 2.82 SR5 is recommended. It's in beta now, so if you used the "stable" 2.82 version, that might be the problem right there.

If it was 1.6GB, than it was the full update (at least one of them). I typed ">1 GB" so any OTA zip for this device greater than 1 GB should be okay. It's the OTA zips that are less than 1 GB that you need to watch out for, as it is not a full update, just a partial "patch" (don't flash on a modded device with TWRP or you will soft brick!).
I don't personally use sideload. While I see the convenience, I find it a bit messy. I've seen folks have problems with sideload, when simply putting the ROM on the phone and flashing with TWRP works fine (so in those cases sideload itself was the point of failure).
Now of course, getting the ROM on the phone is the problem, in your case.

About your issue, use TWRP bluespark 8.61, just to be sure.
Never had issues with this version.

If posting on a thread, related to your issue; it would make sense to actually read the responses in the thread. Since your question is already answered.
In short, you need to use SuperSU 2.82 SR5. The "stable" version 2.82 won't work, and will result in no boot. Or use Magisk 16.0.
If the phone still won't boot after (only) flashing the proper version SuperSU or Magisk; then flash the full stock update file using TWRP. Then flash the right version SuperSU or Magisk.

Thx))) I was very much waiting for this.
I'm now at 20a. if I flash the bootloader only, then the fingerprint scanner will work on custom firmwares? Does the custom LAF work?

very welcome. if you flash the bootloader only it will leave whatever laf you have untouched, and yes fingerprint scanner will work with custom ROMs like AOSP Extended.
However, I have not tested running stock 20a with the 11g bootloader. But it doesn't sound like that's what you are wanting to do
*edit*
if you have already flashed a custom Rom and FP doesn't work, simply flashing the 11g bootloader zip will fix it. it is not necessary to reflash the rom
also, not sure why anybody would want to, but 11g bootloader with stock 20a rom will not work. it will hang on the boot logo indefinitely which can be dangerous for your phone. so please make sure you are using a custom Rom or stock 11g with this bootloader

Any way to flash one of these stock images. Rom itself. If you can't get into twrp? Check my post from last night in the root thread and you'll see what I'm on about.
Phone boots but system ui stops which keeps me from getting in. Lost twrp from recovery somehow. All I did was apply a then through substratum and it all went South from there.
Not hounding ya just thought I'd prefer over here and see what you been up to.
When I run step 1 in that root thread I get no hash match and something about with laf or lafbak not being present. Haven't fully fired up the pic too see if I can post the output from that here. (Honestly, was never that good with logs lol)
I'm curious though if flashing your laf (how in the heck it happened is beyond me) if it's possible through adb or lgup would put me back to right.

Do you still have root? if so you can extract the laf.img file from the StockLAF zip and use adb shell to push it to the dev blocks
put the laf.img file on your sdcard and rename it to laf.bin, and run these
adb shell
su
dd if=/sdcard/laf.bin of=/dev/block/bootdevice/by-name/laf
dd if=/sdcard/laf.bin of=/dev/block/bootdevice/by-name/lafbak
that will restore stock laf

Have to have root eh? So I'd need dl mode back to flash the kdz to get root but can't unless the kdz restores laf in the process which if it did this wouldn't be required I'm thinking.
Sorry man just thinking through things.
When y'all are putting in " /by-name/ " it would be h-872 right? Stupid question I know but I've never seen it mentioned straight out anywhere

Yeah you need to restore stock laf another way if you dont have root. Root is needed for ADB shell.
and no, /by-name/ is the actual folder name. I think it's a directory of symlinks, but i might be wrong. Basically it lets you access a partition or mount point by name. in this case the names of the mount points would be laf and lafbak

Thank you for this weaknpc! This is really saving my a*s. Quick question. If I flash the FullStock version, will I have to unlock the bootloader again? I am using the AEX rom (have twrp 3.2.3 on laf and recovery I believe) and just want to go back to the full 11g firmware. If this works I wont even worry about flashing the laf partition (I would only do that for using LGUP+11g kdz).

Glad I could help, man. No, none of these will lock your bootloader. They wont touch your recovery partition either. If for any reason you want to go back to stock recovery let me know, I can pack a zip to flash that from your LAF TWRP if you still have it.

Awesome. Yeah, I am going to give it a flash tomorrow morning. I do not think I will need the stock recovery at this time, but thanks for offering! I have been stuck with the whole twrp on LAF issue, not being able to use LGUP, and this just a godsend to get back to 11g. Thanks again! :good:

You are most welcome! But important FYI, I discovered an issue in the original FullStock zip that was causing the laf partition to be flashed over with stock. I am posting an update to the project with another handy file for people with TWRP on recovery. If you downloaded FullStock prior to this morning, you will probably want to reboot to recovery and flash it.
Flashing h87211g_TWRPLAF.zip from custom recovery will put TWRP back on your LAF partition.

If I were to downgrade if able to, would that have a chance? I still am getting stuck in fastboot mode unless I'm hooked up to the pic and let lgup do it's thing.
It detects the device, does it's thing, reboots it and gives me a factory reset phone back just no dl mode.
It's not bricked yet lol.

Ok, so the flash did not go exactly as planned, there was some issues getting into recovery. Let me give you a run down of what I did.
1. Boot into twrp recovery using a reboot app (requires root) from a working rom. (This is really the best way I can get into recovery besides using adb) 2. wiped the system/data/cache/dalvik cache partitions. 3. Flashed the FullStock zip. 4. Flashed magisk and it was unsuccessful (it was not able to mount system or vendor partiton I believe).
I did not realize you need to reboot into recovery from twrp recovery, then flash magisk for it to work. I thought it may have flashed anyway. Needless to say I booted into the system and I had no magisk so no root. When trying to boot back into recovery using the hardware buttons, I could not get into recovery. It took me to the factory reset screen. Usually at this point if you select, yes factory reset the device, it would boot into twrp (I think this is some initial mask that lg puts on the recovery partition? ), but this time it was just a orbiting rainbow colored cicle animation. At this point I was saying "oh fu*#!". Then once that animation was over the phone began boot looping. I thought I bricked the phone at this point. Then I tried getting the phone into download mode by holding the volume up and inserting the usb cable. I got the download mode graphic, and then a second later, bam I was back into twrp! Lol. Crazy. I guess twrp was still on laf after flashing FullStock! So, I think that maybe your FullStock zip flashes the stock recovery partition and not the stock laf partition.
Now I was in twrp I was back in business. This time I did the steps correctly and magisk did flash, however I did not format data so now I was getting the encrypted data issue when booting into the system. Then on the third attempt I booted back into twrp using the download mode trick and this time I got it all right. 1. fully format data partition to clear encryption 2. wiped the system/data/cache/dalvik cache partitions. 3. Flashed the fullstock zip. 4. reboot into recovery using the option in twrp 5. Flashed magisk successfully. 6. Reboot into system 7. Phone booted fine, no encryption issue, magisk manager sees magisk is installed and I have root.
So this is where I am now. The phone works fine and I have root. I am afraid to flash that laf zip with twrp becuase if I am correct, there is some specific hash that has to match the device when twrp is on laf. There are steps regarding this for the root method for the H872. Maybe it works on your phone, but I don't want to assume it will work on mine. I would not like to brick this thing, lol. Maybe I don't know what I am talking about...
Also, everything on this rom works great except for bluetooth audio! For some reason bluetooth audio is super super low even at max volume. When I had 11g before, it wasn't like this so I don't know what the heck happened! Through the headphones you get a prompt asking if you want to raise the volume above the limit but nothing like that for bluetooth. Does anyone know how to fix this? (Btw, I thought magisk viper4adroid might solve the issue but it does not work for me with this rom. I tried it and it just crashed system ui after reboot, almost got in a bootloop from it. Luckily I was able to disable the module after another boot)
So, if I can't fix bluetooth volume, I will be running this for a while, then I will flash the stock laf to get real download mode back and do a full kdz flash using lgup so I am truly back to stock. Then I will follow the H872 root process from the ground up, etc.
Either way thanks for this npc. At least I am able to have 11g! Thanks for your hard work. :good:

I'm sorry that you had a little trouble. It actually makes sense that you needed to format data. I will update the instructions to start things off with that step.
The actual, proper procedure, would be to format data, reboot back to recovery, wipe system, data, dalvik and cache and then flash FullStock and Magisk.
I'm glad you still had TWRP on laf. Maybe I was looking at an old updater-script. I do know, however, that I removed the recovery flash from the rom so that never should have been replaced. What I think might have happened with you is the Stock firmware's recovery repair feature. Since Magisk didnt flash correctly and you booted to OS, it would have tried to repair stock recovery.
As for the TWRP LAF zip, it is an exact image of the LAF partition after it was processed by @runningnak3d's root procedure. So there shouldnt be any checksum issues at all. It should be totally safe.
The bluetooth thing is probably the most puzzling to me. I extracted all of the images in these roms directly from the stock KDZ. Your system should be a mirror image of any device flashed with LGUP.
Try flashing the SysBoot ROM on top of what you have now. The file structure in that rom is different. Instead of extracting a system image to your system block (the way fullstock does) it actually flashes all of the individual system directories to their designated blocks. I have a feeling that it may fix your issue.
Thank you very much for the information. If you end up doing anything else let me know how it turns out. If I can help you not have to flash the KDZ then I'll be happy. That was my main goal in creating these packages.

Ahh yes this makes sense. Maybe it was a stock recovery repair due to magisk failure as you mentioned? I still don't understand why with these LG phones (ever since the G3 I think), when you boot into recovery using the hardware buttons, it asks if you want to factory reset the device. Then if you say yes, it doesn't reset/format anything, and it boots right into twrp recovery after that. So weird. I can boot directly into recovery just fine from a reboot app or adb from a running system without getting that factory reset screen...
I'm sure your laf zip with twrp works for the reasons you mention. Luckily I don't have to find out since my laf partition is fine and still has twrp!
Regarding bluetooth, I will give the sysboot flash a try and update you with the results. First I want to wait until my backup phone is running again. I bent the sim pins on the backup phone due to those ****ty plastic adapters that catch the pins (an old E980 w/ the larger sim size) so I ordered another sim reader to fix that. I also read in some forums that wiping cache and dalvik cache resolved others bluetooth issues with the G6. I will try that too.
Either way, I will update soon. I am happy to share my notes as I really appreciate the help!

I'm rooted and running an old version of aex. I'm still getting the encryption message anytime I try anything without that rom. These last two posts. When you talk about formatting your saying in twrp correct? Or that forced format you can do with the buttons?
Basic point is I'd like to get rid of that encryption message and it looks like your instructions take place after we achieve root. I'm wondering if I should just kdz to 11g and root from there. Or would just flashing your full stock zip do it? I seem to be the only one having such an issue with it so I'm figuring I'm missing something somewhere that y'all are doing or whatever that's getting by me.

What Encryption message are you talking about? The one in TWRP where it asks you for a Passcode?
So far, I have tried removing dm-verity and force-encryption from both the 11h and 20a kernels, but I have not been successful. The OS always ends up encrypting data. However, after I flash Magisk I no longer get any passcode prompts in TWRP. I am able to backup and restore system and data no problem.
The only thing I have not tried is a rom packed with dm-verity and force-encrypt removed and root built in. That is the next thing on my list once I get a deodexed 11h rom done.

Yes that's the message I get. So your saying not to worry about it for the moment? I only see it regularly on a stock rom when going into recovery not aex.
I just wanted to make sure. With the mess I been going through.
So, I can flash this stock build you have and if I wanted normal download back flash the laf zip and I'll have DL mode on laf, twrp on recovery and everything should Mount correctly and all that?
And if I go to flash something custom FP will work? I know I'm a pain I just want to "know" my setup isn't weird somehow. Probably over thinking it, but I think I'm good, except that when I rooted I was getting that message off & on, on the stock build of 20a. I'm hoping that running this build I can get that worked out. Maybe that deal is a 20a thing? Reading through the root thread it seemed to happen less to people on a lower numbered build and it would stop after the format.
I can make backups Burt I've yet to try to restore one.
