Hi,
I was gladly using CM7 for a month now but now these things started to bother me:
android.process.acore stops unexpectedly. (very frequent)
google processes stop unexpectedly. Viber, Tango contacts do not show up.
when I read mails in Gmail app, unread ticker still remains.
lower video playback compared to stock firmware.
no radio.
Now my plan is to revert back to stock firmware ONLY keeping root privileges.
My questions are:
1) Which firmware should I select? (there are tens of different firmwares for different regions) Does it matter which one I choose?
2) When I flash the stock firmware, does the kernel remain the same? Or will it be replaced with the kernel inside the stock firmware?
3) When I flash the stock firmware, do the root privileges remain?
4) Which kernel gives the best performance with the stock firmware? I guess CF-Root and SiyahKernel are some of the best options. Which one do you suggest?
Thanks a lot!

It's easy enough, just takes time. But what you read and learn will be for your benefit in the future.
Never used CM7, but flashing a stock firmware - as you want to do - is probably the best solution for your FCs.
I'll start you off - I'd use XXL1 or LA4 firmware and CF root if I were you. The rest is up to you

Thanks alot! I've found Gingermod, its quite cool, nearly stock excluding all the ****ty Samsung apps.
Then I've installed siyah kernel on top of it.
Cheers!

Hi,
From my own experience, Gingermod is a good choice, just take care to one point Siyah on top of Gingermod will prevent you from using the OTA module of Gingermod... This is not a major issue but always good to know
Cheers

Hi all,
I have a mini pro/U20i running Eclair, specs as follows;
Firmware: 2.1-update1
Baseband: M76XX-TSNCJOLYM-53404006
Kernel: 2.6.29
Build no: 2.0.A.0.504
Rooted, xrecovery installed
I'm looking to upgrade to the latest stable android version available for my phone, but must admit the in-depth tech talk does go over my head a little when looking at the ROM threads. I have enough tech savvy to be able to flash etc, but not too great with the programming speak.
I'd like to ensure that bluetooth, wireless, root, gprs etc are all 100% working on the ROM I upgrade to. Not bothered about radio or anything you can get an alternative of from the market.
From what I've seen gingerbread is available but not yet 100% functional, and I know there are stable Froyo versions available however the requirements state the baseband as above, but ending in 53404015 is required.
Is there considerable risk flashing a ROM if my baseband is slightly different?
I'm particularly looking for stable multitouch too, but the thread I read says manual edit of .sh and .prop files must be done - and I don't know how to do this
Dev and user opinions would be muchly appreciated.
Hi you will need the newer baseband just update with seus then you will need to reroot and install xrecovery again then once you have done that go to this thread ( http://forum.xda-developers.com/showthread.php?t=1059361 ) its the most stable I think and dual touch is included so no messing around
Hope this helps you
Sent from my U20i using XDA App
just use the flasher and baseband files from the baseband thread. much faster and easier than using seus and rooting again. just put the rom you want on with xrec, pull the battery out, flash, and youre done! shouldnt take more than 10 minutes once you know what youre doing!
For me, using SEUS is safer, even if I have to root and install xRecovery again.
I you want the most stable ROM with all functions working, you have to choose CM6-MiniCM hybrid noOC from Slade.
I'm using that ROM since he released it and never had a reboot, and everything is working.
If you have stock rom, you should format SD card.

yeah using SEUS is better... and you can reflash after you update using it....
after root and xrec, just make a backup on xrec so you can reflash to 2.1 back... and dont waste time on reflash+root+xrec again.... i did that save lots of time
ps: make sure full wipe+dalvic clear before restore backup... ^^

Yeah, I did it too, but never needed that backup I flashed with SEUS last, when I first updated to slade's ROM

Cyanogen Froyo CM6-Latest (based on MiniCM/CM6v2) - v2.0 + DualTouch is the most stable ROM for me. Just flash using SEUS or flasher to get the required baseband.
I recommend using the flasher because it helps you understand the flashing process. Just follow the tutorial.
Thanks for all your help guys, that's helped me out no end
I am now the proud owner of an x10mp android 2.2.1 (went with Slade's ROM - big thumbs up, it's beautiful!!)
I have one final question.. when I installed the last ROM I had, I used flashtool, so doing it with xrec was a new experience for me... I did notice that before it installed the rom, it said 'formatting /system' or words to this effect.
I need to install the two hotfixes that are posted with the rom - the drain and browser ones... do I package the files within these zips into an update.zip and run again from xrec or can I transfer the updated system files just using root explorer? I'm worried that xrec will take the update.zip as a full rom and will delete the contents of my system folder - please reassure me this isn't the case and it will just update with newer files!
MANY thanks again for your help and advice!

Just use each from xrec, it will replace some file but it won't format your system, only the big release file does that (100MB++).

It depends what formatted, deleted or owerwrited on update script. Don't worry, slade knows what he's doing
Anyway DON'T TRY TO FORMAT YOUR SYSTEM WITHOUT INSTALLING NEW ROM!!!
Just always follow install notes and everything will be fine.

Right then, an update (excuse the pun!)
I followed SEUS to get the xx 4015 baseband
I flashed Slade's noOC rom and then hotfixes using xrecovery
I now have a happy 2.2.1 android mini pro with multitouch!
At first, it was a little slow and I had a few blank screens and FCs....
Screen brightness was very low even when I was actively using the phone, so I unchecked the auto display option and set a brightness I'm happy with. Sorted!
With Titanium I restored my backups, including my wifi connections. Saves having to re-enter all the passwords right? Wrong!
I had a number of connection issues. Data was very slow, to slow to even register my google account on market. Wifi wouldn't load market or bring up anything in the browser...
When I did establish a fast enough data connection, market was completely out of sync with my phone apps.
Turns out the data connection just needed to 'warm up' along with the new android system. As for the wifi, I removed all my connections with the 'forget' option, and manually scanned and entered the passwords again. Now my wifi flies
So all in all, a very smooth upgrade process, a couple of hiccups with the data/wifi and brightness that have been ironed out, and now I am loving my new android again. The multitouch is very slick and having superuser, jit and xrec preinstalled is just brilliant! Games are lag free too which makes a big difference (yep, I'm an Angry Bird club member)
Think I've made my iphone user hubby a bit jealous. I like to remind him every now and then that apple have him by the balls, and he has to buy a whole new phone to do any update such as the one I've just done (again )
The battery drains a little quicker than on the previous rom, but I expect that will settle down after a few days. One thing I have noticed is that I'm repeatedly ending apps with ATK that I hadn't even opened - on my last rom I'd never see anything that I hadn't opened myself.
An example being, just opened ATK and I have the following running;
APN OnOff
Gmail
Maps
None of these I've opened since I last ran ATK Other repeat offenders are Browser, google search and camera,
Any ideas? WhatsApp used to open randomly until I moved it to the SD card. It's behaving itself now.
Don't need to use taskkillers in 2.2.1, android handles battery quite efficiently.
Battery increase is due to overclocking and because it's a custom rom.
Hope that helps.

My battery life has stabilised now. Took phone off charge about 8.30 am and now, 1.30pm it's at 83%, so can't complain
I find apps such as maps and google voice/search do drain the memory quite a bit so still prefer to use atk. Just opened atk to find I have;
maps
handcent
apn OnOff
gmail
google voice
ROM manager (I've never opened this since installing the rom)
calendar
camera
all running and memory at 41M. Killed apps and memory now at 71M
Is there a way to stop these apps from randomly running? Apart from a calendar alert for today, I haven't manually opened anything from the list
cheers,

Sorry for ignorance:
Can I flash a rom and do all the nec. stuff from Ubuntu? Or will I need Window$ to flash a mini pro?

It's normal to have applications taking up memory. It is so that it will be speedy in opening those apps so try not to use a taskkiller. The only time these idle apps use battery is when there is CPU usage: so check with your spare parts. If they don't use CPU, no need to kill.
If you're insistent that the apps are frustratingly persistent, then freeze the app using titanium backup. Note that freezing certain system apps may cause problems eg freeze google talk and market won't work.
Try at your own risk.

Can i get the link to ''CM6-MiniCM hybrid noOC'' Thanks
On my Galaxy Tab 10.1 running 'In Paris V4' with preshoot's kernel I have the following problem:
Android media process hogs CPU (47%, which means 100% for one thread on this dual core device).
The device was running fine for a few months, so the problem is not the ROM/kernel but was caused by something else later on.
I would like to fix this problem (without reformatting/reflashing the whole ROM). If there is no easy solution I just want to disable it, but could not figure out how.
Killing the process helps for some time, but after some minutes/hours the process is back. I tried 'pm disable com.android.providers.media' as well as 'pm disable com.android.providers.media/com.android.media.MediaScannerReceiver' -- both with no result (it helps for a few minutes but then the process is back again!).
I don't know how/where this process is started so that I can make a modification there to disable it or which package I should delete to get rid of the process.
Any help/suggestions are appreciated.
This obviously seems to be the wrong board I am posting that supposedly simple question in -- could somebody please point me in the right direction and I will ask again in a more appropriate board.
I'd say the board is the right one ... but at least I can't help you here, as I don't know the answer .
My only advice would be to flash a newer ROM, isn't inParis kinda "outdated"? I think android.media has something to do with connecting USB devices to the tab, since it's the thing that crashes on ICS KANGs when you plug out your USB stick ... but that's all I can help you with (if it's any help)

Honestly, I was going to say that you'll spend less time doing the ICS update than looking for this; especially on that ROM (great ROM.... 6 months ago...). I'd suggest go with the last milestone from Romann.

Next thing to try is to clean dalvik cache.
Thanks -- tried to flash latest Milestone and b26 releases. Unfortunately VPN is not working and I can only download apps via marked when connected to a VPN (even if this does not change my IP as I often just connect to my Router). So -- until VPN is supported with any ICS ROM I am stuck with my old In Paris 4 (with pershoot kernel to mount SMB shares via CIFS).

I can understand if you'd just rather wait because of having to bother with reinstalling every thing, but it looks like you can change ROMs quickly. So why not goto Task14 while you wait for ICS?
There might be device issue I'm not aware of also, so just wondering.

Hi all.
My girlfriend has had the S3 for some 6 months now. The phone is not rooted, and is updated to newest firmware.
A month ago the stock gallery app started to freeze, when entering the gallery. Pictures are shown, but after that no response when trying to turn to next page or showing a pic.
A week ago the stock browser stopped showing pdf files, but only seems to be downloading endlesly.
We have tried to do a manufacture reinstall wth no luck. Firefox browser opens pdf documents with no hassle.
What to do when stock apps start to behave like this? Is there a way to uninstall and install stock apps again, without having to root the phone?

Stock apps are embedded ion the firmware files so apart from a factory reset or reinstall of stock firmware i would take it to a service centre .
Root has no bearing upon the problems and will not really help .

For the Olleh ROM (2.3), the Gallery process --com.cooliris.media keeps loading automatically despite manually killing it.
I am so frustrated as this process seems to chew up the DS5's battery.
There seems to be 2 processes related: The usual Android Gallery process --com.cooliris.media, and one that looks like a OEM provided one: Gallery version Stage_1.5.1_KT-113.
Please help me: my phone's not rooted (long story...), and I am looking for other ways to stop these 2 apps from loading / running up all the time.
Any advice, any kind of apps recommendation that I can use to pin these 2 processes down is most appreciated.
Thanks!
Root. It's the only way you'll be able to kill the process permanently, since you can then remove the offending app. However, you'd be better off rooting and installing a custom ROM such as DSC that fixes many of the bugs found in the Olleh KT ROM.
so i never modded or rommed my phone this time. and nearly 2 years after, my phone is slow as hell. is this natural--just bloat builds up over time? if i try to send someone 2 consecutive texts, i have to wait ~1 second after the first text before i can type the next because of lag
i was wondering if updating my OS would help here, or ironically make it worse because of the old hardware.
thanks!
The S III is a good piece of hardware.
If you just update the ROM probably it will remain slow.
To speed up things you should root, backup your apps using good backup utility. I use Titanium Backup.
Take a look here: [Guide] Noobs guide to use Titanium Backup for backup and restore of apps.
Then you must wipe your phone, install a new rom, either stock or custom, restore apps and your phone will be up to speed again.
Titanium can also restore messages, call log and wifi accounts, but use the xml version of backups to restore.
And DO NOT restore system apps or other system data.

Just normal OS behavior after a few years of use, running dozens of apps and installing and uninstalling a lot more.
Also happens with windows. I always do a fresh install of Windows when moving to a new version.
As your phone runs 24/7 all the time it will become slower.
Sure you may take some preventive measures, but my advise is to use it to the fullest and just do a clean reinstall if/when you feel it is necessary.
And if you just do a dirty install, without a wipe, all crap and leftovers accumulated over time will remain there.

Please do not compare it to windows as this is not completely true. Read up on linux based operating systems.
Install a 4.4.4 rom to benefit from better security and features or atleast reset the phone if that is as far as you want to go,
your firmware your running is probably outdated for this newer stuff, when the art changes in the system you need to update a couple of things in the system or hardware for it too work. If id were you id update my firmware, modem, and bootloader but just make sure you don't update with sammy's new knox special feature lol.
After updating to the latest stock ROM, removing knox is not a problem with Chainfire's root method.

What error are you getting in Odin? Are you able to post he Odin log?
Just thought I'd chime in with some proper explanations.
Your phone has bogged down because the hardware is old now and most apps consume more CPU power than the phone can provide. Couple this with the ever expanding nature for RAM and the device will be under a lot of demand. Devices now are at least twice the hardware.
Now to the operating system itself. Android is not windows, nor linux, nor Unix. It is CLOSEST to Unix, derived from Linux and nowhere near windows even if you're blind and deaf and can't tell the difference. It really is a "bastard". The nature of android is to cache data for speed. Once this cache is full or resources run low, or android just can't kill an app for whatever reason it will bog the os down so bad the device will become unusable. I could demonstrate this VERY easily by filling up the internal memory with crap apps and dumb data and watch the device slow to a standstill (even the htc m9 I'm writing this on right now is susceptible). It's the nature of Android that causes the bogging down because it has run out of resources. It is THAT simple!.
Can we solve this bogging down by shutting down the offending apps with things like "greenify" or "hibernation"?.
The answer to that is "NO". Short and simple, you'll make the situation much worse if you attempt to hibernate apps. This is because the os will call for the app under its "normal allowances" which are defined by "permissions", you may have noticed these on some of the googleplay "read more" page when browsing an app. There are also permissions that you cannot see, one example would be "startup" which allows the app to start when the phone boots up. You CAN stop these startup apps at boot but if they continue to run you're best leaving that app alone. The reason being is that the OS will call the app, the app WILL respond. Then whatever app you're using to "control" other apps will detect the call and intervene, attempting to shut the process amd services down, the OS will detect this as a fail to load so it'll invoke (call) the process and service again, the "control" app steps in, rinse and repeat. Without knowing you've just waged a war in your phone between 2 apps and the OS. This will murder the resources and battery power.
So, after 2 years of normal operation your phone has become slow. You now know that the problem is that the phone is outdated because it is struggling to provide for the resource hungry apps that are out there (this is about as "in common" with windows as it gets).
Custom roms will be a waste of time. The reason is that custom roms are open source code, are very rarely optimised and not really compatible with the proprietary hardware they have to control. Although you can unlock extra potential it will be countered by the poorly written code. The custom rom will bog down in half the time of an official firmware.
I'm afraid I'll have to be the first to admit that your phone has now surpassed its life cycle. The only way to get better performance at this stage is to upgrade to a more powerful device. Not exactly the news you WANT to hear but it is the most honest advice you will find in this thread.
A LOT of people don't quite understand how android works as an operating system but they'll be quick to give you advice that is only partly true or not true at all.
The odin problem. Kies can be installed but the processes must NOT be running. Stop the kies processes in task manager.
As audit13 said, the output window in odin, we need to see that so we can determine whats wrong. We also need you to make sure you know what model s3 you have and that you have the correct firmware for your phone. Double check them in the settings menu.
