[Q] Laggy performance after JB 4.1.2

Hello there..
I was on stock ICS.. i installed the stock JB and the performance was very laggy even worse than Honeycomb, i was advised to backup my apps via titanium backup, wipe cache and data from the cwm recovery and restore my apps again. I successfully did that and the performance was a little better but lots of apps crash and restart, the biggest problem is when i open any app specially a web browser or a game then go to home screen or use another app for a while and get back to the browser again its like i open it from the beginning "the browser tabs reloaded and if a game it restarts".. This problem was on honeycomb and was solved by installing Go Launcher and was fully solved by installing the ICS.. Is there a solution for the JB to get that performance back?

JB is very good and much much better than HC or ICS...
So I guess your concern would be the backup/restore procedure...
When you restored from TB, did you do a full restore or just apps restoration ??? ^^
If you did a full restore : including system files and configuration, then this should be your issue...
Try to do a factory reset (no need to use cmw, just from your settings) and only restore your apps, and see if that helps ?!?!?!
As another option, use the Google or Samsung backup/restore procedure... ^^
I know, I know, Samsung Kies may suck sometime... But some other times, it may help...

I really appreciate u took time to read and answer so thank u so much
i backed up my apps and few system stuff like Bluetooth and wifi points and alarms.. i've been told that some apps may not be compatible with JB that's why it crash and close
so do u think i should do the backup again before the factory reset ?
Still i can't find an option to backup my apps by kies, i can only see few things to be backed like contacts and sms not the apps
and i dont know what is Google backup restore thing, i googled it but i only find apps on play store

There seems to be TRIM (or flash handling) bug in official firmware [SOLVED]
I had official ICS 4.0.2 firmware on my Galaxy Tab 7.7 phone (GT-P6800), but it becomes slow and sluggish and I was unable to do anything. Even popping up screen to accept phone call was so slow, the caller hang before I was able to do. Also writing on touch keyboard was really slow and unusable.
I tryed to reflash, I tryed Slim version of official firmware too with no luck. The system was faster, but even no apps were added (just system update through Google Play), the responsibility of the system become sluggish again (and even worse than before).
Then I recognized that even I pick firmware reset from CWM or from Settings (in Android system), my internal flash memory is not deleted and many (hidden) files remains there (one may think that internal flash was empty, because hidden files are not normally shown). As I had some applications making A LOT of (hidden) files (maps, geocaching, etc), the clues become visible to me. [I tryed to do factory reset from system and from CMW too, so there could be bug too]
To make story short, I manually deleted all files in internal memory (by running "My files", tap on Menu, and pick "Show hidden files"). This takes LOOONG and then the system become more usable, but still not enough.
And yes. There is legendary TRIM command which makes flash memory to know what portion of the flash memory is free to use. Without that even one deletes files, the flash itself does not know that the place is really free and keep data on it. When TRIM command is used, the internal FTL (Flash Translation Level) system in flash chip can use place marked by TRIM to spread writes and wear level writes to not destroy some parts of flash with excessive number of writes (they are limited to 10-100 thousands times or so). The TRIM allows FTL to breath. So what now? Android officially support TRIM since 4.3, but there is no 4.3 version of Android for Galaxy Tab 7.7 at all, only 4.1.2 (but only for East Asia officially). But this is better than nothing. Maybe Samsung put some support to 4.1 (backport?) as Samsung do for other features or (maybe) fix some other issues related to flash support? I don't know...
Then I decided to go to 4.1.2 from from here and wrote some info to the Wiki. And I reflashed, deleted cache, Dalvik cache (from CWM), then I fill up space in internal flash memory and then deleted all files from "My files". And viola! The speed is incredible again
To the end - maybe it is not necessary to go to 4.1.2, maybe just make sure you delete all files (including hidden ones). But I does not care about it. I have KIES_HOME_P6800DXMD3_P6800OLBMD3_1157844_REV00_user_low_ship.tar from URL mentioned above (no M3D DEODEXED was put on top of it). This is East region stock firmware and I happily use it in central Europe (SMS, normal call works, MMS was not tested yet). The only thing that seems to not work is support for 5GHz Wi-Fi (I don't see it in Wifi Analyzer) but I do not care and I'm enjoying full speed of my 7.7 again Sorry for long post. Just FYI.

This happens when Dalvik cache contains data about more recent applications (ie. you install one with older time mark than was before). You have to go to CWM and delete Dalvik cache (in Advanced menu). As I wrote below, there could be bug even in CWM so you may want to try 6.0.3.0 (I have this now) see link.

[Q] HELP!!

I rooted my galaxy note pro 12,2 and uninstalled a lot of original apps. The uninstaller was unable to restore them, therefor did a factoryreset in hopes it would be as new... It did not, now the files are lost forever and i did not take a backup before I started the rooting Is there a way to do a proper factory reset, where all the original apps, settings and files are restored?

Hi!
1: You don´t explicitly state this but it sounds to me like you still have your device up and running. At the very least to the level of being able to do a reboot.
If this is the case then do the following:
If you can then connect the tablet to a computer to wich you have Kies 3 installed in the latest flavour.
Access whatever you want to save and back up to PC.
If you cannot access the file system currently i see no way around ditching your user files.
2: Go to Sammobile.com and download a bog standard Rom from your area and possibly your provider
Follow instructions on the site for installation. See this example. (Note: You have to have Kies 3 installed for the drivers. Even if you can´t back up user files)
When you have reinstalled a std. rom you can reroot and try again.
Regards
Elo

P3110 - Multiple ROMS, Same issue... (Slowness)

Hey,
I am on my last ditch attempt of a fix here, I have installed multiple roms to my P3110 and whenever I play on specific games the device slows them down, the sound and the game play around 50% slower than normal.
I have tried CM12, Candy5, SlimLP, Slimkat and the only fix I have is to go to Stock 4.4.2 Jellybean and lose move to SD Card functionality.
Any assistance would be appreciated as I was using this tablet for my sons xmas present and would love more app space.
Thanks.
*EDIT* It seems any other jellybean rom works, it just has trouble with KitKat and Lollipop...

Hello, and Merry Christmas.
I am going to have this thread moved to the Galaxy Tab 2 help forum, where there will be experts with your device that can help you resolve your issue.
Best of luck!

The thing is you need not need a custom rom. Stock roms is better, As there is this app called XPOSED which have a lots of facilities like moving obb files to sd card by just copying it to sd card, changing the navigation bar to the lolipop nav bar etc...it is a useful app. Here is the link install this app and install the framework and reboot once. Then search for obb 2 sd In modules., install that and reboot. Now once u have dwnloaded a game with obb open it once and then close it. Now you can move thae obb file to sd card in folder android» obb.
Here is the link for xposed.http://repo.xposed.info/module/de.robv.android.xposed.installer.

I've tried Xposed but it isn't working correctly, and I was having an issue with the device being slow beforehand so I thought I'd use a lighter rom and everything ran perfect bar gaming apps...

Greetings;
Stock ROM's are the Safer (Less Bugs) but have tons of garbage (Bloatware). Wich Consumes quite some Battery and Memmory.
Custom ROM's on the other Hand can have tons of Bugs, Perform Faster, Consume More Battery if they are Cyanogen Mods, and sometimes Brick your Device.
In any case fear not. As it is most likely to be solved quite easily.
I'm not Expert on This Specific Device (actually just got this tablet), but the solutions are very similar for each Samsung Android Device, ROM Version or Other Brand.
1) Download your p3110 ROM (Stock ROM) (You can get it from Sammobile Website)
2) Perform a Clean Flash (You can check my Thread for i9003-SL in order to know how to perform a Clean Flash)
Thread for i9003-SL Flashing Tutorial (http://forum.xda-developers.com/galaxy-sl/general/rgxhost-ddlf2-complete-tutorial-t2837212)
[IMPORTANT REMINDER]
- The Thread Link i Mention Above is Just for Reference on how to Perform a Clean Install;
- The Files in that Thread ARE NOT for your Galaxy Tab S2;
... The Thread serves for Reference so you can Learn on how to do things Properly.
3) When your Device Starts on it's 1st System Load, interrupt it and boot it under "Recovery Mode"
4) Under Recovery Mode; Clean Dalvik, Cache, and then Perform a Factory Reset. (Don't worry if you don't have the Wipe Cache or Dalvik Options; you can skip these and direclty go for the "Factory Reset" option)
Note: Personally i prefer to clean both 1st, and only then perform the "Factory Reset". But that means you have to Flash ClockWork Mod Recovery in first place.
You system should now be like it came from Factory.
Also: I'm not entirely aware or "Triangle issue".
I mean, this device comes with Flash Counter. Therefore if the Triangle comes up, i really can't help you. At least not yet. As i've never had such problem.
If you happen to get this issue: Search for p3110 thread: "Triangle Away"
Let me know how it went for you.
Best Regards;
Richard

If u get that triangle problem just connect your device to pc and start flashing using odin like you did before.
I have the same device I had the same issue.
But remember this thing, if u get stuck in boot loop after flashing firmware using odin just try going to the recovery and then perform a factory reset. Then you are all set to go..

Thumbs Up m8!
The thread i mentioned about the "Triangle Away" (i just made a quick reading so far) felt like it was more difficult to solve than that.
Thanks for the Info. I was kinda worried on what to do when i get that "Triangle".
So, a Clean Flash and / or Factory Reset would Solve the Problem? Just That?

Flashtool Settings

Hello
I'm trying to update from 41.2.A.7.35 to 41.A.7.53 using flashtool. I am relatively familiar with Flashtool at this point. I have installed stock firmwares a couple of times. Each time I have flashed a firmware i checked all boxes in the "Wipe" pane giving me a fresh install.
What i was curious about was, how can i prevent from formatting my drive each month when a new update rolls out. So what setting do i leave checked and unchecked in the flashtool? I'm mostly concerned with retaining apps and appdata along with settings and messages.
Thank you

I normally mark all in wipe section. Today i flash customized AU without problems.

normally no wipe neccessary

If you do not upgrade the Android version, or go from 39... to 41... or you have "strange" behavior before or after the upgrade: do not wipe anything
Some partitions like /system are overwritten anyway. If you are root you might get away with wiping cache/dalvik if anything feels strange.
When switching ROMs or upgrading Android versions I use Titanium backup to shorten the process:
- look for unsaved apps after upgrade -> bloat candidates, let TB delete deal with them after looking at the list and deciding what to let go
- restore all user apps with data
- manually restore all logins of apps that have accounts e.g. email (the time consuming part)
I use Apex launcher and its setting are restored too, so I will have a familiar look and feel even on a different ROM.

Various troubles with my OnePlus 7pro (rooted) + questions about restoring Nandroid

Dear community, I am facing several troubles with my OP7pro which I think can be quite easily handled but my knowledge is just too little.
I am running OOS 10.0.2 with Renovate ICE, rooted with Magisk and on TWRP 3.3.1-70 - stock kernel and normally encrypted. I am facing various troubles that started after upgrading from 9.5.13 tot Android 10. I do not know if they are directly related. I do have Nandroids, BUT the phone is my daily driver, also for work, and a factory reset will just take too much time.
What are the troubles you ask?
- I am not able to enter the menu Buttons&Gestures/navigation/set up navigation bar. The screen blinks and I am back in the upper menu. If I press this menu again I get a "Settings stopped". This sucks, because I want to set up my on-screen buttons
- I used to use Plus Beat in combination with RICE on Android 9. Worked perfect. Whatever I set up, Plus Beat just does not work. That sucks big time.
- I am not able to set on screen buttons to for example switch between recent apps or get anything else but horizontal recents (which is slow and to me sucks). QuickSwitch via Magisk doesn't bring anything.
NOW TO THE QUESTIONS:
I GUESS (! but am not sure!) that a factoryreset could and should solve these problems. I could and would do that, but, I need to be up and running and have my settings back quickly. Internal memory (root) I could copy to PC and paste back afterwords. But is there some way I could put my settings (in the menu) and all my apps (250+) back via Nandroid data?
I have the following things backed up in TWRP:
- Boot
- System Image
- Vendor Image
- Data
- Modem
- EFS
If I do a complete new factory set-up (for example via Maurefranio's tool), to refresh my system (I guess the failure is in there), can I put back other parts of the Nandroid to have all the rest back? Also in the menu-settings, color-setting etc. etc. etc.?
I know it sounds rooky, but I hope someone takes time to help me a little. I do use Titaninium etc. but I can't spend hours and hours on a recovery. In that case I'd probably decide to keep using the OP7pro as I do, but it's frustrating that RICE and Plus Beat don't work fully and some other errors. The usability to me is 4 out of 10 - where in Android 9 it was surely 9 out of 10.

Are you running a substratum theme? That could be the settings issue. But that's about all I could help with. Never restored anything using twrp on this phone. Most I've done is backup my apps with swift backup, factory reset, or MSM tool, and restore my apps.
How quickly do you need your phone up and running? You could backup with swift backup, factory reset and only restore what you need for now then do the rest when you have time.

@GeekMcLeod: no, Substratum not even installed. All this trouble started after the regular update to Android 10.
But more my question is: IF I flash the whole phone back to factory setting (not a reset because the errors might still be there so a complete whipe and re-flash) - which part of Nandroid is usefull to get SETTINGS and APPS back? Just that. The internal memory I can copy and paste back.
I really hope someone can give me a quick instruction of how this works. Much appreciated!

In that case, I would just use swift backup, backup to your device. Transfer SD card contents to your computer, factory reset. Transfer SD card files back. Swift backup can backup all apps and data. I believe that would work for what you want.
I, however, do not know what parts of the nandroid do what as I usually just don't bother with it.

GeekMcLeod: appreciate your advise, but Nandroid is there for a reason.
Is there anyone who can please help me what to do best? I mean, one of those Nandroid-partitions holds the clue, right?
I am also facing overnight Batterydrain of about 30% (from 80 to 50 in about 7-7,5 hours).

No Nandroid specialists in the house?

You need to wipe your data. Use Swift to backup apps, messages and call logs. Google will do it's best to restore settings upon setup. Your problem is almost guaranteed to be in data. If you need that data, I would recommend going back to whatever version of pie you were on before. Swift won't restore app permissions, as far as I know so be sure to double check if you restore apps with Swift.
