[Q] How to get rid of "System UIDs Inconsistent"?

I was on 4.2.1, rooted, and with TWRP as recovery.
I wanted to get the OTA to 4.2.2 so I did full Titanium backup and then used the WugFresh toolkit to flash stock 4.2.1.
After flashing, I was offered the OTA which I allowed to install.
When finished, I got root back with Rootkeeper and restored all Apps and Data (not System data) with Titanium.
Everything was working, but on every reboot I got the message :
"System UIDs Inconsistent. UIDs on the system are inconsistent, you need to wipe your data partition or your device will be unstable."
I also found that My Phone Explorer would no longer connect via USB so I decided to go back to 4.2.1.
I again flashed it with the toolkit and did another restore with Titanium. Again, everything seems to be working, but I still get this message on every boot.
I thought using Titanium Backup was a standard way of restoring apps and data.
How do I get rid of this message without wiping and reinstalling all my Apps individually, which means losing all my game scores, etc?

I also see that in Bootloader there is a line
"Signing - not defined yet".
I do not know if that was there before flashing back to stock.

same problem
system UIDs inconsistent, it keeps showing up after every boot.
i have nexus 7 GSM 32 gb rooted using nexus 7 toolkit with clockworkmod recovery, android version 4.2.1 build number JOP40D

I found the answer in another thread. I used TWRP (Advanced - Fix Permissions). It was instantly fixed.
I took a full backup before trying this, but didn't need it.

You can boot any recovery you want without hard-flashing it to the device (so long as the boot loader is unlocked).
With the device in bootloader/fastboot mode,
Code:
fastboot boot name-of-recovery-image-file.img
So download TWRP and give it a roll.

Hello,
I got the same "System UIDs Inconsistent" problem. I like to solve my problems myself but I've got no way out this time, so I'm asking for your kind help.
I'm on the SGS III, i9300, I rooted it then went to Omega ROM, and then to Paranoid Android. Everything went well until I got a battery problem (when charging the phone, it was not sufficient to bear with it functionning, so it powered out while charging). After that, the phone restarted and the UID problem appeared. Maybe it's just a coincidence.
So far, I : fixed permissions, did at least 10 factory resets with TWRP, changed ROM (went to CM and came back to PA as nothing changed).
I read the 6 first post about this in xda forum, and other forums too, but nothing came out as an evidence.
Last thing I did was upgrade my PA ROM : the phone couldn't even go beyond the booting process, failed to initiate the phone "first settings" app.
So I came back to the previous version of PA, and was able to use my phone again, but apps like Gmail, Color Note, won't work.
I want to get rid of that, and I wish someone told me, step by step, the things I could do to eradicate the problem. I will do what's necessary to achieve that, I only need someone who knows what to do, and how to do it. I saw some tricks that maybe could do the job but I don't have the knowledge to choose one.
That's my first message here so I hope I didn't break the rules of the forum ^^ If you want any informations about my device to help me, just ask
Thanks a lot, and I hope my english is not too bad ! Have a good day.

Thanks
I got this message too without having any other problem with this TWRP version or Hairy Bean 2.2
The message appeared after flashing the new 4.2.1 (?) modded bootloader for Hairy Bean and the ROM itself.
I'm not sure whether the ROM or bootloader are causing it but mine got fixed by fixing the permissions via TWRP.
Thanks for the tip! :good:

In my case only re-partitioning helped.

for me uninstalling quadrant did the trick

That did it

This worked for me, too. Thank you.
My situation was a little bit different:
- Flashed Paranoid Android 3.99
- everything was fine (for a few reboots) until I made a nandroid back up with CWM 6.0.3.6 ( which was surprisingly slow, almost 1,5h)
- rebooted
- UID consistency problem
- tried to boot temporary into TWRP - NOT POSSIBLE!
- flashed TWRP 2.6.0.0 permanently
- TWRP: advanced - fix permissions: SUCCESSFUL!
Maybe I'll keep TWRP, but I'm used to CWM for years now.
CWM has removed "fix permissions" since 6.0.3.5 (http://review.cyanogenmod.org/#/c/45945/ )

Fix Permissions
For me worked fixing permissions through TWRP on CM 10.2 latest nightly (10082013).

Me too! TWRP on SlimRom 4.3
Thanks

I am also having this issue after I flashed SlimBean Beta 4 Weekly-409 on my i9300 (wipe data/cache/dalvik and clean install with gapps) and tried restoring a couple of apps like Any do and Temple Run 2 with Titanium Backup.
Is the TWRP being referred here mean the TWRP manager? I installed it from play store but I don't find 'fix permissions' option anywhere in it.
I remember of seeing it in SuperSU but I am unable to install that as well as it says the binary needs to updated.
Could someone please help me here?
Thanks!

Confirmed. Get into the TWRP n do a fix cache wipe/dalvik wipe/fix permission

Thank you for clarifying this fix

I just updated my S4 to 10.1 Hyperdrive and experienced this very same issue. Rebooting into safestrap and fixing permissions cleared up this very annoying issue on my phone.

I flashed gummy V4.4 yesterday works great. I went into rom toolbox and changed LCD density to 361 and rebooted, got the UID inconsistent message.
found this thread, fix permissions in TWRP, all fixed. bing bang boom.

thanks all, I also fixed with TWRP latest version, and try to roll back to CWM

I installed a new ROM and I got the System UIDs inconsistent error, then my S Planner FC. I went to find the txt file and it stated that the problem is related to Calendar Storage. I deleted the apk and placed a new one back in. Problem persists, I scratched my head for so long and then I found this thread.
THANK YOU, fixing permission for the Calendar Storage did the trick! Thank God I found this thread!

[BRICK] Phone stuck in bootloop after ODIN

Hi!
So, i was playing last nice and my phone suddently rebooted, then, got stuck in bootloop.
I re-flashed stock firmware, cleaned data and cache, didn't fixed, so i repartitioned, still no changes.
What else can i do to try and restore the system?
I still can go the Recovery mode and download mode, however, recovery cant write logs to the /data folder.

you can either do a full data wipe - wipe data wipe system wipe cache
mount everything
install hells fusion kernel #50
reinstall rom
or
install stock rom via odin (find full list of stock roms on dorkys thread in development section - its a sticky at the top)

As i said on the bricked device thread, i already did that, and it didnt worked.
I get to the Samsung logo, after a time, it stops when the logo is very bright, then start the boot animation again.
It looks like it is not Reading the system.
Also, going to try the method mentioned up here.
I will feedback in a few moments.
Also, is there a problem if i use the bootloader that you gave me on that thread on the Brazilian default firmware?

[Q][Root/cwm lost?]

Hi guys,
Recently I updated my i9505 to official 4.3 version XXUEMJ7...then i rooted it successfully, flashed philz cwm, it worked...i did a backup, then flashed a mod (lightning effect on lockscreen), turned on the phone. Suddenly my wifi won't work so I decided to do a restore from the backup that i made 10 minutes before that. While it was restoring i noticed that i didnt had enough storage so it skipped few things. When it was successfully restored, I turned my phone on and here are the problems:
When it has booted up i recieved so many errors and fc's like procedure system has stopped, com.google.process.gapps error and so on...
I taught ok, lets delete some HD games to gain space and restore it again. But now there was no cwm or any recovery. I can't use Google Play and every app that uses Google files (youtube, gmail, stock internet browser and even facebook)
I'm not sure if I lost root and/or cwm. My question is how to get it back? What do i need to flash over Odin? Download mode works.
Sent from my GT-I9505 using xda app-developers app

Hello.
I have same problem. Nothing works. I think it's a protected bootloader that will rewrite every custom rom/recovery. I had rom for ~20 days, and was just doing my daily routine, rebooted and lost root and CWM. After this same symptoms occured.
I downloaded XXUEMJ7 prerooted now, and it was only rom that I could flash. Have no custom recovery by now and root works... But probably not for long. What's most important - wifi works. This is partial solution for using your phone while someone smarter will explain us what's going on.

In this thread, use "ctrl+f" and write "PDA: XXUEMJ7" There will be prerooted odin flashable link.
By the way, flashing this new knox bootloader with 4.3 was worst thing that I done do my phone. And I'm really pissed off on samsung. Hope some smart devs will solve this someday and we will be able to downgrade or bypass this.

Need help/overwhelmed! Noob flashing to GPE 5.0.1?

Hi,
I want to install the ROM here on my Samsung Galaxy S4 (GT-I9505). I rooted and installed CM on it about 4 months ago, but since have forgotten anything about the process except for towelroot lol. My phone is currently running jflte snapshot M10 ROM for CM. Unfortunately, I have grown quite sick of it as I find I have to restart my phone once, maybe twice a day for everything to run smoothly. I run into problems where the WiFi likes to get stuck saying 'Turning on..'. Ive also been having problems with Google Maps and GPS lately and havent been able to rely on it, possibly its an issue its having with CM. I want to have the fresh Lollipop feel on my phone without any problems if possible. The only trouble is I dont know how to get there. Can anyone help me? Ive completely forgotten the process needed and when I try to look for it on here I am overwhelmed with things I need to do, which version I need to use etc etc. If anyone would be able to help me achieve this it would be greatly appreciated. In the end I just want a nice Lollipop android phone that doesn't have problems on my current S4 (Id rather not have to get a new phone at least until December ) I'm pretty sure I dont have a custom kernel or anything like that as it mentioned in some pages that I will need to get one I think? I also have philz CWM installed.

You have Philz installed, so you don't need to root again. Download the ROM and follow the instructions on the page.

It also mentioned to make sure I have the latest modem for my variant, how do I check/update that?
In regards to the kernel (which has a link on the same page), what do I do with that?

I don't have the latest modem for my I9505 and that ROM works perfectly fine. Where you've been on a custom ROM for a while finding out which modem you're supposed to use may be difficult. That's also why I recommend not worrying about it, unless you need to.

Ok thanks. In regards to the kernel that is linked on the page, I guess I would be at an advantage if I downloaded and installed that too. How do I install it?

If' we're talking the same GPE ROM, and I think we are, the kernel is included in the ROM download. You'll be prompted to select a kernel when you run the install through the recovery.

Ok thanks a lot!
So process:
Backup data/photos etc
Nandroid backup
Full wipe using philz?
Flash ROM
Done?

You've got it.
When you are prompted to select the kernel, use the Googy Max kernel. The stock kernel sometimes causes random reboots. Also, on first boot the S4 will sit for a fair amount of time before prompting you to set a language. THIS IS NORMAL. It's because Android 5.0.x uses Art instead of Dalvik, and has to compile the apps the first time around.
In other words, after rebooting, just be patient.

No, they are gone forever.
How is that even possible that you wiped them? Wiping in the custom recovery never touches your internal storage by default. So you have done it yourself. You probably did a factory reset from within android itself. Never do that again. Use the custom recovery for wiping only and you never will have this problem again.

Are you sure about that? It happened the first time I flashed a ROM. Wiped cache, wiped Dalvik through CWM. Never did a factory reset. No need for caps.

No it's not possible for it to happen without you doing so. Unless you encrypted your phone or something.
ps removed the caps

The rom he installed has an aroma installer which offers the option to do a simple wipe (Dalvik, cache and data), no wipe (Dirty flash) and a factory reset (which also wipes the internal storage).
By default it is set on factory reset option.
It also says in red letters that this option is recommended.
So maybe he left it on factory reset (since it was also recommended) , instead of changing it to simple wipe, and that wiped the whole phone, including the internal storage.
Will a software that recovers deleted files not work? Since the phone wasn't encrypted.

It would if Windows saw the internal storage as a drive. Due to MTP it doesn't. He'll have to do a search, but there was another S4 owner who lost his photos and was trying to get them back. I don't know if a solution was ever found.

If that's the case then shame on the developer. A factory reset in a custom recovery should leave the internal storage intact.

No it's impossible. Once it's gone the files are permanently gone. Not even a professional company can restore them. That's because of TRIM that Android has from version 4.3.

It's not in the recovery. It's in the aroma installer. Those are 2 different things.
Besides, there is a description, under each setting, of what each one does.

@Lennyz1988: Perhaps you should bring this up with the developers of the ROM and see what they say. I suspect they have a very good reason for wiping the internal storage, and my gut instinct tells me it has to do with the Android folder on there.
On the flip side, thanks for the homework you gave me. I have to look into what TRIM is all about, as my last device was powered by Gingerbread.

Nexus 6p weird bootlooping.

Hello xda community!
I received the nexus 6p christmas and after a few hours playing with it, I unlocked, installed twrp and installed cm13. I then installed ak kernal. My phone installs both fine and runs as normal without any FC. Then this is where it gets weird. When I had my new rom and kernal all set up. I go into TWRP and create a backup. I restart and I'm bootlooping. It tells me my device is corrupt. It did this with the original backup of stock rom, cm13, with and without ak kernal installed... and then sometimes my phone will soft-brick (gets stuxk on google logo) I really love cm engine as I habe a theme. But I'm unsure what is happening to my phone.
Any help is appreciated! - thanks.

The bootloader message won't go away until you lock the bootloader. Its just there as a warning to you in case you did not unlock your phone. As for CM I'm sure there are still many bugs to be worked out. I know I'm going to wait before Flashing it until I see people enjoying it as a daily driver. There are some great devs here in the n6p forums though so I recommend checking out some other ROMs too.

No it isn't necessary to wipe the userdata partition. No modifications are stored in the userdata partition. It would only be necessary to wipe system, data, cache, and dalvik cache. And probably flash the vendor partition too. Not userdata though.

I had a similar problem when I botched a SU flash, same warning then it would take forever to boot, then the rom would degrade over the next several minutes. I know its not fun to start over, but it was the only thing that cleared all the problems. I didn't want to take more time finding another solution when going back to stock is so simple with this device. Follow the instructions in step #11 of Heisenberg's guide (great guide, I link it to friends a lot). Then start again, I know, not what you wanted to hear. Hope this helps!
I am also in agreement with Heisenberg in regards to the userdata partition.

Thank you very much for replying. I have found the root of the cause but no solution. Uninstalling or disabling system apps will cause my phone to go into a "optimising apps" boot loop on the next restart. What do you think? ++ every restore I make on twrp either soft bricks or bootloops. Crazy!

If you are sure about reason Forget ur Backups.
you should completely install Stock Kernel, Rom, Boot.img >> Back to Stock
But If I remember correctly u did this before...
I just have to say Retry Also Install and use Nexus Root Toolkit

I have reinstalled original stock files from google. I've wiped everything numerous times. Installed ROMs just after. It took me a while but I think it comes down to the system apps. I'm running a custom ROM, cm13 and my phone is running fine. I know if I was to delete all the unwanted apps off my phone, on next reboot it will try and optimise apps, finish. Says starting apps... Then reboots. Follows the same process.

Can I ask what gapps are you using? Are you using your google account to recover your apps, or are starting fresh each time?

Thanks for your reply. I've actually now narrowed itnright down to a few apps, maybe gapps. Sound recorder, voice recorder app and the google app. Either one or more of these cause my optimising apps bootloop.
