[Resolved] [Q] I've made a mess of my Nexus S...

Hey guys,
This is my very first post, just to let you all know, so please have some patience! Thanks!
Anyway, so I have a Nexus S 3G (Canada) and I have rooted it, unrooted it, installed roms and everything. I works...for the most part. It's giving me all sorts of different little errors and what not. So I was wondering, how can I COMPLETLY start ALL OVER, as in, factory new, like when you buy a new phone (without the carrier stuff). I wanted to start fresh, fresh out-of-the-oven kind of start, do you understand what I mean? FACTORY FRESH. Thank you all so much in advance!

well download your phone's stock rom and of course unroot it.Regarding the stock bloatware you can modify the custom rom by going in system/app and deleting the apps you dont want to be installed

Thanks for the reply, I've already done that, and I'm still getting errors and other weird things, like not going out of airplane mode, failing to download the OTA 2.3.6 Update (I'm on stock 2.3.1 unrooted, I think), and I don't know if this is normal, but ClockworkMod Recovery is still there. Am I still rooted or something? Plus, when I try to flash a restore, from let's say Gingerbread 2.3.6 Stock, it says MD5 mismatch! How about if it's an ICS AOSP Build, it gives me the normal white Google logo like normal, but then just stays stuck there.
Is the anyway to erase EVERYTHING and start over like NOTHING was ever done to the device? Like when they are first distributing the the device and no one has ever touched it? Is there anyway to do just that?

There is a difference between being "rooted" and using a rooted ROM. You could be using a non-rooted ROM, and your phone can still be "rooted". The first step in rooting a phone is changing SECURITY-ON to SECURITY-OFF. If you REALLY want to go back to when you first got the device, you will need to find a way to turn SECURITY from OFF to ON. When it is off, you are able to access the bootloader, in turn allowing you to install a recovery to install a ROM with rooted permissions. I think the best way to go back to stock would be for you to first download the latest OTA update for your device, do a FULL WIPE of everything on your phone thru recovery (data, system, cache, dalvik cache). Then installing the latest OTA. I do not think however, that this is how you turn your device S-ON.
I hope I've been of some help.

Thanks for your excellent reply, but I have also already done that, EXACTLY that, multiple times too. Dalvik, battery stats, factory reset/delete all user data, wipe cache partition and fix permissions. What else is there left to do?

Thank you all so very much!!!!

Sometimes packages like that have been known to remove the Settings app. The only way to fix it (except factory resetting) is to flash a custom ROM, like CyanogenMod.

Wich CM can i install? Because the lastntime i've tryed it (7-8 months ago) it was really bad and buggy. Honestly i prefer the Samsung ROM.
However, can i install a new settings app? Or flash it. I need the secsettings.apk from the 4.2.2 JB Rom for i9105p. Or the only way is wipe data/factory reset? (It will wipe data and i'm scared that i can't have my settings back this way).

Up

Well, if I had that device, you can be sure that I'd provide you with that settings app.
However, since I don't have it, I don't know of any way to obtain that app.
By any chance did you make any sort of backup any time before this issue occurred? If so, please post it for me, as I might be able to extract the app out of that.

Safe Way to Downgrade from LL to KK SM-N900

:good: you may know that when u flashed a new firmware mean you'll flash a new bootloader with protect boot you'll MOD EDIT when you flash something wrong with that bootloader you're phone will completely dead my experience of my two device xperia Z1 and Samsung Grand 2 :cyclops: there only one way to unbrick it is to go to phone repair service change motherboard (because we cannot write any programme on it anymore)
Now if you flash LL you want to Downgrade KK
DO NOT CHECK AUTO REBOOT IN ODIN PROCESS !!
Download this clear warranty bootloader :
http://www.mediafire.com/download/d0fw56n3ucj66oh/BL_HA3GZS_CLEAR_WARRANTY_BIT-4.tar
if you flash it success but not see any change of bootloader logs you have to flash it again it'll work
LL bootloader be like :
PRODUCT NAME : SM-N900
CURRENT BINRAY : CUSTOM
SYSTEM STATUS : Custom
REACTIVATION LOCK(KK) : OFF
Secure Download : Enable
KNOX WARRANTY VOID : x
AP SWREV :A4
IF YOU SEE CHANGE OF BOOTLOADER LOGS YOU CAN FLASH KK Firmware without any risk and you're device will reset knox to 0 auto unless you're root or install custom recovery :laugh:

Wow...BRILLIANT GUIDE...that means my note 3 is long ago dead and what I am typing on is a BLOODY GHOST or ZOMBY?

Note 3 sm-n9005
Hi. I installed the leak android 5.0 onto my note 3. I let it on about 85% charge and when i woke up only 60% chargin was left. Now this is not usual as on my kitkat it only use to drain about 3 to 4% in whole night.
I tried to revert back to 4.4.2 but offcourse it gets stuck on the samsung screen and then restarts over and over. Just wanted to know if there is a safe way to get back to 4.4.2 on the sm-n9005 without tripping the knox?
Btw i am now back to android 5.0 so currently running fine.
Just curious to know the way to get back to 4.4.2.
any advise would be greatly appreciated.

aqi1992, you'll need to do a factory reset and a partition wipe from the recovery menu (power off, hold volume UP+home+power buttons to enter). After that it'll boot fine but you'll have to reinstall everything.

Hi. So basically i will need to do the above before flashing the stock 4.4.2?
That means once i have wipes the cache and factory data reset it then after i dont let it restart and straight away flash it with 4.4 2 stock?

No, I was stuck where you are now. I had flashed 4.4.2 successfuly but it wouldn't boot. So I did what I mentioned in my previous post (AFTER flashing) rebooted, and everthing was fine.

Ok. I get it. I did try factory data reset but didnt do partition wipe. I will try that and feed back on it.
One last question, will i be able to get ota if i put stock 4.4.2 when android l comes out?
My knox is not tripped yet.

I expect you will be, but I wouldn't know for a fact.

Well thank you. I will give android 5 a couple of more days and if it still drains battery then i might revert back.

As per my experience (read about it here), at least I'm downgrading.

I have to say that i have tried android 5 on my oneplus. I have had note 4 which i recently sold and currently using the note 3 with android 5.
The thing is i wont call kitkat a joke or neither i think the colors here are bad looking. I think the samsung implementation is much better than plain android. But again hey thats just me.

Hey i have just tried above and it doesn't work.
The phone goes to either samsung logo or sometimes even before that it's just in bootloop. It went to the upgrading android only once when it was stuck on 72 out of something and i had to restart it but after that it never worked.
Also when i flashed android 5 i also flashed the .pit file that came with that. and also the bootloader file so it might be the bootloader file that is initiating this problem.

first attempt at this seemed to be going ok. after flashing with odin i tried to restart manually (think i pulled battery cause i couldnt reboot via PB).
immediatley went to recovery mode to flash new rom. didnt wipe nothing but flashed ketan k12 rom, and got stuck at samsung logo. went to reboot and got weird red screen (of death) i thought but continued on into download mode, where i saw the change you mention. Anyways cause of the many reboots i did to see if the dam thing was stuck i reverted trying to flash kit kat via odin (didnt work). went back to download mode after more failed attempts to boot correctly, i decided to flash lollipop back onto my phone via odin. still didnt reset factory in recovery, and now im back to square one lol.
so my guess is that i messed up cause i didnt factory reset for a new rom, but answer me this please... is it normal to have that red screen cause i didnt restart download mode correctly. you did mention not to have it check, so how am do i restart correctly? thankyou in adavnced (unless i figure it out before your reply LOL).

Thanks. It works. I had NL4 bootloader installed.
Now I just want to know that can I flash any other KK rom through CWM with this above said bootloader safely, as I did earlier when I had KK bootloader installed ?
Thank you once again for your suggestion.

Can't run "system settings"

Hi. I have a Oneplus one bought few years ago, never updated. Since few days I can't run "system settings" app : when I click on the wheel or on "system settings" nothing happens!!!!!!! So I can't pair a new bluetooth or wifi device .......:crying:
Any "easy" solution?
Thank you.

unlock your bootloader maybe, flash twrp and flash new rom, it might be rom issue, maybe

Thank you, but is there not a easy way like downloading an system settings app?

Can't you just factory reset? It will reinstall system apps hence fix the issue.

Thank you.
When I read things about OPO factory reset, I can't understand what it erases exactly. I'd like to keep my apps and personnal datas.
Do you somethings about that?

Well, you could "dirty flash" from fastboot by flashing everything but userdata.img it will keep all your data and fresh install the OS. But only if you are running stock COS.
https://forums.oneplus.net/threads/mirrors-for-official-cyanogen-roms-ota-updates.141825/

Ok. But how can I know if I'm running stock COS (I can't access system settings)?
What I know is that I've bought the phone 3 years ago and done nothing on it (no flash ......) so I think I run an official three years old OPO OS.
So is it a stock COS? (stock OS?)
Thank you for your help.

Ah, so you have the bootloader still locked, which means that to unlock it you would have to factory reset.
You should really backup your stuff and factory reset your phone. I do it once a month or even less.
One more thing I can suggest you is to delete cache, either system app cache or the whole system from the recovery.
Boot to recovery and wipe cache.
Hope it works, if it doesn't I really advise you to factory reset.
COS = CyanogenOS

Apps stop working

Hello everyone
I broke my phone so I took one of my friend's old Nexus 5 which was not working and I tried to make it work.
However, I'm a complete noob. The phone wasn't turning on, so I used Nexus Root Toolkit in order to flash Android 6.0.1 M4B30Z
I had a lot of troubles, got stuck in booting loops and I couldn't solve it, even by wiping the phone over and over. So I finaly decided to flash Pure Nexus Hammerhead, and the phone finaly turned on.
However, all the apps are crashing (I'm not talking about store apps, but the one on the phone. Let's say I want to go in my settings, then the "settings" app will crash.
Sometimes, apps don't crash but the phone just freezes.
I don't know what to do anymore, that's why I resquest your help. What should I do to have a working phone ?
Thanks

Anyone can help me and tell me what to try ?

Sounds like you need to clean flash, factory reset as well as wipe system in advanced wipe in twrp before flashing ROM and gapps (I recommend Beans gapps minimal, not the full package) Make sure to wipe caches after flashing. Also make sure you're flashing an up to date build of Pure Nexus https://forum.xda-developers.com/google-nexus-5/development/rom-pure-nexus-substratum-t3477787

Hello,
So I went to TWRP and clicked "Wipe", checked everything and restarted. Now I only have the "Google" screen displaying, and I'm not sure what to do to solve that
