Clean Install? - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi all,
I have a Z3C running the latest version of Android (for me), 5.0.2.
I've noticed the phone is running a bit more slowly lately (though not hugely) and I'm wondering if a clean install would be beneficial. I upgraded from KitKat to Lollipop without wiping the phone, I'm not sure if that would have any performance impact.
How can you do a clean install on Android? Is it as simple as reinstalling the software from Sony's PC Companion? I'm not sure if that is a true clean install or simply a reset to defaults.
Any tips would be appreciated!

Mostly 5.0.2 ROMs have bugs. You need to wait until Sony releases it's next version.
Clean install:
If your phone is rooted and have recovery install (cwm or twrp) you can do a clean install.
It is the process of wiping/deleting
system+data+android secure+cache+dalvic cache ( in short deleting everything) and flashing ROM.
As the data (junk) from the previous version remained after updating to newer android version, it gets cleaned and phone works well.
Hope you understand 'clean flash'

Thanks for the reply! A clean flash sounds like it would do what I want, but unfortunately my phone isn't rooted, and I don't particularly want to root it. Is there a way to clear everything out and reinstall without rooting?
I'm looking for something similiar to how you can restore iPhones.
Thanks!

You can try full factory resetting phone through stock recovery. To do so follow below steps;
1. Switch off your phone.
2. Switch it back on and the time when you see your phone’s LED notification light turn Pink! (or any other color) — start pressing either the Volume UP or Volume Down key a couple of times to make your phone boot into stock recovery mode
3. Once you’re in recovery mode. Use Volume buttons to navigate Up and Down between options and Power button to select an option in recovery.
4. Select wipe or factory reset (similar to this)
5. Reboot
Also after this process, open your file manager and delete 'Android' folder from both sdcard & ext sdcard (phone will start hanging) and restart.
(This process will delete app data,cache & their folders)
(A deep factory reset)
If still your phone behaves similar like previous, it's software issue, you need to wait for an update from Sony

Rooted or not, personally I do a full factory reset aka "wipe" aka format at least every 6 months. Just like a PC, apps you install and uninstall leave crap behind that clogs up the file system. Seems like there's always some Google bug every 6 months, too, and a wipe seems to resolve most of them. There's no harm in doing it. I do not let Google back up all my settings, b/c I prefer to manually set everything up after a wipe (esp since I may be wiping due to some setting anyway). I'm not sure, with the ridiculously powerful phones these days, if wiping will actually speed things up. For me it's more of a spring cleaning type of thing. Er, I guess more like an anal retentive geek type of thing

Which is the proper way to downgrade from cm11 to cm10.2?

I upgraded my p1000 from cm10.2 to cm11 few weeks ago but the latest cm11 seems to be a bit laggish on my device and I'd like to go back to cm10.2, first of all... is it possible? If so, which is the proper way to do it?

I'd recommend you try OmniROM Its what I'm using on my "P1" and although it has its share of problems. Wired Headsets don't seem to be working. Its no more worse then CM10 was, and on that note why CM10.2 which like CM10.1 was broken beyond use? The only decent CM10 was CM10 from 2013 - 02 - 03. Which AFAIK was the last fully working CM10 Mod for the P1000. As the 10.1 and .2 had the Camera Bugs.
In any case Omni is pretty well supported with near nightly, or at the lest every other night updates. As long as you don't get crazy with it with Live Wallpapers, like my Old man was trying to run on it. (He too has a P1000), its pretty damned responsive. But. Again you ONLY have 512MB of RAM on the P1000. In some rear cases even less then this!
In my Fathers case the same sh-- that was causing his CM11 to lag like heck, was the same crap that was making the fresh install of his CM10 (version as dated above!), lag just as bad. So you might want to first clean up such resource hungry Apps as you have first.
But, on the Latest OmniROM for the P1 (Int't GSM version), as of 06.08.14 (Which is still the the most current at the time I wrote this), just running the Google Now Launcher, and a few widgets. The Tablet doesn't feel any considerably slower then it did back in CM10, and the Google Now Launcher is a KEEPER! I can't imagine wanting to roll back to CM10.
P.s. Did you remember to reset your Firmware + wiping the Cache Partition, and Dalvik Cache? This could also partially explain your problems. If you, had not done this.
P.p.s. Download your ROM, and appropriate GAPPs Package, then reboot your P1000 by pressing both the Volume Up, and Power Button till you see the Galaxy Tab / Samsung Bootloader Screen. Then release the Power Button, while continuint to hold the Volume Up till you fully enter the Recovery Mode.
Once in the Recovery Mode do the following Factory Reset, then Wipe Cache Partition and the Dalvik Cache (Advanced Settings). Then install your CM10.x ROM from where you stored it i.e. the /Download Folder? And when thats though. Your GAPPs Package as well. After which you then boot into your new ROM. Which might take a few moments longer, on the first boot as the Database(s)? have to built from scratch again.
Mmmhh I think I'll follow your suggestion and I'll try OmniROM. Have you used the CWM recovery or the TWRP suggested on their official wiki to flash the omnirom?

The way I described it before was for CWM. OmniROM uses TWRP. The ideas the same, in fact its a bit simpler on TWRP, in as far as it simplifies the wipe progress. Just One TIP download and install SuperSU, and run it. Once your rooted, go into your System Settings and click on the SuperSu Setting, (near the bottom), and it should ask you if you want to use a backup script, to keep root! You should run this if you want to... Need to keep Root for say AdAway. As OmniRom does NOT ship out with Root... WHY?! I can't say.
Other then that the only other annoying things I dislike about this ROM is that I have to keep uninstalling the Apollo Player. as well as reinstalling the Xposed Installer reset the "ro.config.low_ram" from true, to false, to re-enable transparencies, as well as other Lock Screen Widgets. After each update. Which again averages about every other day. I use something called ROM Toolbox Lite to do this, as trying to do this manually I always seem to gimp my install to a point of bootlooping.
But, other then these little niggles I actually like this ROM! for the most part.

Hi everyone,
This ROM is great. every things are working well.
But I don't know how to change the "Right hard key's function. I don't want it show the "recent apps" when we press.
It should be a menu key when we using App.
Please support!
Thanks,

no root after flashign WizCyan
After flashing WizCyan 4 with update 1 I don't have root access. I've tried reinstalling several times and I've also tried to install superSU on it's own using CWM, both the latest version and older versions, with no success. I've also tried to install just v4 but the problem persists. Does anybody have any clue on what could be wrong? I've had root on the phone using other ROMs. I use the latest CWM.
And yes, I chose no when promted to fix superuser in CWM. Although I have also tried to pres yes during one installation.
What version of cwm are you having? Also when you click on the supersu app what message do you get?
I used version 6.0.3.5. Today I installed 6.0.5 and redid the flashing of the update and also of superSU 2.16 by it self from CWM. No difference
When i press the superSU app I dont get any message really. Looking at the log it's as if though the app denies all apps access without asking. I tried changing the settings in superSU to allow all requests and then the phone passed the check with root checker and root apps also seem to work. No app is added to the SuperSu applist.

I would suggest that you do a clean install of the ROM, now that your recovery has been updated
Excessive consumption of battery
Sorry, but this was translated by google.
I found a big problem in version 4 and is the battery, prior to this version, the battery works well, the battery lasted the whole day, but now the battery hopefully enduring three hours.
Please, give solution to this problem or any suggestions, as I really like this ROM and do not want to change the other.
Thanks in advance.

Ok, did some testing and found that some of the init.d scripts were eating battery therefore have posted an update in the OP removing these and battery consumption should be better after flashing this update.

Sure, you can install on any firmware, but if you have wifi issues then you may need to flash modem or some other workaround. Just wipe data/factory reset and install version 04 followed by update 02. I am not sure on what you mean by memory but presume that you are referring to internal sd card. This will depend on what apps/features you install from the addon package and playstore. The ROM will not affect your internal sdcard space as it will be installed on the reserved system space.

In case you want to use screen mirroring then you would need to install allshare from the addon package
I've been tinkering with trying to get WizCyan totally working on my device for a couple of days, but I can't for the life of me get Wifi working (at first it was root access, but that was fixed by upgrading CWM). Here is the exact process I've followed:
Updated CWM to 6.0.5 (PhilZ's version)
Did a factory reset from recovery (I didn't use the "Clean to install new ROM" function)
Installed WizCyan version 4, followed by update 2
Rebooted, attempted to configure WiFi -- failed.
Flashed the NE5 modem package from the links in the dev thread, using Odin 3.07 -- twice each, as instructed
Still can't get my Wifi to enable. The flash was successful, as I can see the correct baseband on the "about" screen, but it refuses to enable. I'm in Australia, but I believe this phone came from UAE -- would that make a difference to the way the modem interacts with the Wifi hardware? I pulled this info from logcat:
Code:
I/WifiManager( 1084): setWifiEnabled : true
I/WifiService( 882): setWifiEnabled: true pid=1084, uid=10008
E/WifiHW ( 882): ##################### set firmware type 0 #####################
E/WifiHW ( 882): Cannot open "/data/.cid.info": No such file or directory
E/WifiHW ( 882): ==========[WIFI] Station firmware load ===========
E/WifiHW ( 882): return of insmod : ret = -1, Exec format error
E/WifiStateMachine( 882): Failed to load driver
E/WifiStateMachine( 882): sendErrorBroadcast code:10
E/WifiController( 882): Wi-Fi driver is unstable. Received CMD_STATEMACHINE_RESET
In the mean time, I'm going to try to source either a local radio, or one from the original region, to see if that helps.

Can't get anything much from the logcat, it refers to a file that gets created on 1st boot you can try doing a factory reset from settings--> backup & restore--> factory data reset. Only backup your internal sd card before doing this as it will wipe your entire phone including internal sdcard and then reflash the modem.

Well if I'm going to go that far, I may as well do it properly and completely restore the phone to stock and start again. When I bought it, the first thing I did was root, flash CWM and a CM based ROM -- it's probably worth starting fresh anyway, I'm only going to be using it for a couple more weeks until it's replacement arrives.
I'm currently downloading the latest firmware for my region (XSA), a 4.2.2 based MK3 build from the end of last year -- do you think I'd have better chances if I restored to a 4.4.2 build (like NE5), or should it not matter if I completely reset the phone to factory settings/software?

Generally doing a factory reset from the phone resets the entire firmware and is helpfull to resolve such issues. if you want to install the entire firmware, I would recommend flashing the 4.4.2 PHN firmware you can get the download link in post# 13. But then there were wifi issues after flashing the PHN firmware for which a factory reset from the phone happened to be the solution.

Thanks for that mention of the firmware, I had the radio from that link but forgot you'd also linked the full package. Google Drive is much faster than the websites I'd been trying to get files from, it took 15 hours to download the XSA firmware I was originally going to use.
You were totally correct, resetting the phone was the solution. I got the PHN firmware, flashed it via ODIN only to find it still hadn't fixed the WiFi problem -- even after a factory reset -- however the process of flash/reset/re-flash fixed it for me -- it seems unnecessary to me, but I guess times have changed since I last tinkered with unlocked devices. I'm happy to say that I now have WiFi working under WizCyan now, just wanted to check back in just in case anybody else was facing similar issues. As painful as it is to have to back up and totally restore, sometimes starting completely fresh is the best solution.
Now I'm off to rebuild my SD Card, lol.

Glad to know that you managed to get the wifi working.
Personally, I did not face the wifi issue after flashing PHN firmware, but know that quite a few have faced this issue as reported in this thread
Normally my understanding and experience is that when you flash different modems / firmware some corruption occurs and factory reset from within the phone resets the partition & firmware. 1st time I experienced this was when I was using a MTK 6575 based device and had amended the EBR, MBR and scatter files to modify the partition sizes, even though these were flashed through mobiuncle tools (similar to odin), the revised partitions did not get changed until I did a factory reset from within the phone. I know that this is irrelevant here but thought that I would share this.

Help with Pure Nexus Project would be greatly appreciated

I am new to my Nexus 6 and new to flashing custom roms. I have read the thread all morning long and still don't feel comfortable with what information I have obtained. I'm currently running marshmallow 6.0 rooted with supersu 2.52. How can I flash the latest pure Nexus project 6.0.1 correctly? I do have TWRP recovery installed and I'm running on build number MRA58R
Make a backup in TWRP, wipe your system partition, Flash the ROM zip and the GAPPS zip, reboot, profit. If anything fails you can roll back to your backup and try again.
Real simple. Download the latest built as well as the latest google apps (gapps)
Reboot to TWRP
Do a backup, so you have a restore point if something happens
Go to wipe->advanced wipe and choose both caches, system and data. DO NOT wipe internal storage
Go to install, choose the ROM and gapps and install them
Reboot
You will now be on the latest. You will have to set your phone up again, and all your text messages, home screen, act will be gone but all your stuff on your sdcard (internal storage) will be untouched.
You can also get real ambitious and make backups with something like titanium backup of all your apps and data and restore it after booting PN, but try to not back up system apps or system data (it should be an option... I dont know, I never use tibu). The main thing you lose without backing up is texts, I usually just deal with it/redownload apps/set up home screen again.
On future updates, unless there are major changes and its indicated by a majority of people in the PN thread, just dirty flash.
That is, backup, wipe caches, install new ROM version( I wouldn't reflash gapps ) this will leave all your apps, settings, ect... But should only be done when flashing the same or a very similar ROM. If you dirty flash and experience problems, go back and clean flash as I first instructed.
So I should not worry about flashing the new 32r radio?
shouldnt this have been one of the first things to learn BEFORE you ever rooted your phone? yea, nice job jumping in before learning your way around. i bet you even used a toolkit to root your device..
Everyone's got to start somewhere. And no toolkit here but thanks for your input! And thank you for the helpful responses.

Hey there simbo, what do you say about flashing the radio?
Sure. Or don't.
Whatever.
The radio is pretty separate from android. Its basically drivers to tell you phone how to use hardware.
FI has certain requirements for activation that may check what radio you have, but outside of that run what ever works good for you., its not going to for sure be any specific one. Newer may often be better but its not uncommon that an older one may work a little better.
Different apps can help you monitor (I dunno which ones... But I know its a thing ), you can also go into about phone -> status -> sim status and check signal strength where lower dBm is better(well a lower numeric value... Its technically a negative number, so higher is better i.e. -113 is worse then -104). This will vary slightly minute to minute and place to place so just taking a glance once won't really settle it for you
I just use it for a day or two, pay attention to how my signal is (just kinda how often did I have decent # of bars, nothing scientific), and check battery stats clicking on cell standby and looking at % of time with out signal.

youre choice. you can try any of the radios, from previous android versions, on any android version. they arent specific. im using the 27R radio. whichever one works best for you, thats whats important

Well, it's all very easy if you read a little. Still i will give you one extra tip in case you start flashing all kinds of roms: You unlocked your bootloader. Before doing that you enabled "OEM unlocking" in 'Developer options'. Leave that enabled (this setting is 'sticky'. even when you wipe the device)!!!!. Leaving OEM unlocking enabled will disable "Device Protection" that causes sometimes a 72 hours lock-out from your Google account.

[Help] Upgrade to newer version rooted and without wiping

Hello i am a person who hates to do things like backup apps just so I can reinstall them after wiping them just for a new version.
But as I need to upgrade and didnt touch rom wizardry for a while I am looking for help.
My idea is to get
from my current prerooted stock 4.4
TO
prerooted stock 5 or 6
so i do not have to wipe hopefully(ev rom change)
.
how would I do that exactly?
Exact info in image I got the rom from this forum.

Thanks for your time. I hope this is possible. Ohby the way I need to do this because AIDE app does not work on sony phones with android 4 any longer it seems. At leastthats what many people reported and I would like to use it as I always get a stupid aapt theme resource error in building my apps. even tried changing theme to holo did not help..
If maybe you have a workaround for that would be even neater because I like android 4.4 more anyway.
That's what I did. 4.4 -> 6.0.1 without wiping internal memory factory reset after, just flashing the rom and twrp recovery. It's recommended to take the trouble to backup & start fresh, but no problems here.
Helium was handy to backup some stuff.
I followed the thread titled: Recovery & Root for MM .575 & .291 LB
..using a crappy old desktop with linux on a usb stick. I did flash Su for root then xposed, for all the good things like adaway, afwall+, titaniumbackup, pmp, sdfix, sdmaid..
Marshmallow is pretty damn slick, its worth it, take your time.
Hi thanks for your answer. I found a prerooted stockfirmware with 6.0 from the same guy i had prerooted 4.4. And no errors whatsoever.
but i noticed some lags here and there whereas in 4.4 everything seemed more smooth. In marshmallow now it feels like sometimes it freezes for half a second. very weird..
Any idea how to fix that?
ActuallyI had 6. 0 before downgrading but I liked the 4 more (look, feeling, compatibility) so I downgraded.
They say the lags will go away after some use..
It may be with not starting afresh (I didn't notice any problems but its highly recommended to), it may be something you have installed or very likely just the new rom 'wearing in'..
I started from stock 23.0.1.A.5.77 to stock 23.5.A.1.291 and applied root, read about the the lags when upgrading and that they go away after some days use as android optimizes (again, no problems here). Try giving it some time and see.
Weird that you talk about AIDE.. was reading about that and Terminal-IDE.

How to upgrade rooted SM-T719 from Android 6.0.1 to Android 7 or 8

Hi,
about 2 years ago I rooted my S2 Galaxy Tab (T719) and now I would like to upgrade from Android 6.0.1 to Android version to 7 or 8. I have googled for instructions on how to upgrade a rooted S2 Tab but did not find anything useful (most info is on OTA upgrades which no longer works on rooted devices). Could someone please post step-by-step instructions (please bear in mind that I only ever deal with this kind of thing once every 2-3 years so I do not have much experience). I have TWRP v 3.0.2 installed (do I need to update this as well?) and the tablet is not encrypted (so hopefully I won't have to wipe the system partition and re-install all the app?!?). Thanks.
I also noticed that there is now a huge variety of ROMs out there. How can one know which ones are trustworthy? The main reason I rooted the tablet was to be able to increase privacy (control app permissions with XPrivacy). So I do not want to install some custom ROM that maybe contains spyware or other compromising features. Any advice on this would be greatly appreciated. Given my motivation (privacy) for rooting, would it maybe be better to go back to Stock ROMs (i.e. non rooted) and simply control web access via netguard (by preventing net access for some apps, they may still spy on my contacts, location, or email but cannot phone home to transmit the information)? At least I would still get OTA updates because being excluded from the OTA channel also poses a security risk in itself I suppose. Ok so any advice would be appreciated.
Thank you in advance!
There is no official Android 8 for our device. If you want 8 or 9 you have to install a custom ROM like LuK1337's LineageOS port. It is as safe as LineageOS is by itself on any device. Only problem you might have then is that calling is not possible anymore for now, but LTE works. If you want to use LOS, you HAVE to format data because it's not compatible at all. If you wanna stay on official Android you might keep it. Installing is done by flashing the official firmware with the correct country code over Odin. This will remove TWRP at first so you have to reflash it by Odin afterwards. For firmware download I always use: https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 and Odin is found by google. If you wanna got the way to LOS you have to do all the steps I mentioned before too anyways to have a recent Modem firmware and bootloader. In that case you just have to flash LOS and OpenGAPPS by TWRP and delete /data aka Factory reset.
Regardless what you do, after ODIN is done, you HAVE TO boot into TWRP immediately to keep it from being removed by official firmware. While you are in there anyways you can install magisk to keep it from encrypting /data
Many thanks emuandco. So I guess I will stick with the Android 7 as I do not want to reformat the tablet and reinstall all the apps. I have started to download the Android 7 stock ROM, but it is taking quite long so in the meantime just to confirm, the steps to follow are:
1- use odin to flash the stock ROM (no steps required prior to this? I simply overwrite the existing ROM? I suppose that I will loose root then and need to re-root the device using the standard procedure as explained here: http://www.samsungsfour.com/tutoria...nougat-7-0-using-cf-auto-root-all-models.html ?)
2- use odin to flash TWRP (I will need the newest version I guess and cannot use the same as for Android 6?)
3- boot into recovery mode to ensure that TWRP does not get overwritten
4- done
Is this correct? Do I then need to reinstall Xposed, SuperSU and Xprivacy or will they be preserved?
Thanks again!
P.S.: BTW, I also found these instructions: https://forum.xda-developers.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627 which are slightly different from http://www.samsungsfour.com/tutoria...nougat-7-0-using-cf-auto-root-all-models.html and require a wipe of the data partition. Does this mean that for an update to Android 7 I definitely do need to wipe the data partition? If this is the case then this would be a major disadvantage of rooting in the first place and maybe I simply flash the stock ROM and do not root at all but go the "netguard" route as mentioned in my original message?
I never used the official Firmware that much. Fist thing I did was going on LuK1337's nerves to get a port of LOS for it up and running So no clue if Samsung manages to keep /data but I guess so. Yeah, looks fine what you list there. You COMPLETELY overwrite ANY modification in kernel or /system, so reflash your mods and root (Magisk). I always recommend to uase the MOST recent TWRP. (https://dl.twrp.me/gts28velte/ should be it in your case).
Ah and looking at your manuals... Check OEM unlock just to be rather safe than sorry if things go mad.
