U think it will solve the problem?how can i know if this a software issue and not a harware ?any way to tell?

The way you described what happened it sounds like software, but without more info i can not say - but testing it out by flashing all factory firmware is often a good start

auto turn off when sim is inserted and battery drainig

i bought x10 mini in february 2012. after some days i rooted the phone. and after some days it starts auto turn off while sim is inserted. and sometimes it restarts automatically. when charger is connected, there is no problem, but when disconnected, it shuts down immediately. and sometimes it turns off while sim is not inserted but the "on time period" is about 2/3 hours. but when sim is inserted, it turns off immediately just aftrer switched on the phone. and there is a battery draining problem too. sometimes, as example, 90% charge becomes 23% after autorestart. i send it to sony ericsson service centre, but nothing has improved. and now i can see the phone is not rooted. please please please help me !

Did this problems exist BEFORE rooting your device?
If that so, you should contact your service center about this problems.
But don't hope for replacement coz ypu already voided their warranty by rooting your device

I think you done something in the rooting process. Try "re-rooting" it again and follow the instructions CAREFULLY, and maybe this will solve the problem.

Whenever you update your firmware you loose root.
So they just updated your firmware so you lost your root...
Other thing first understand what is rooting..
As in our phone we are not able to access root directory of our device like drive C in computers..
So rooting is just like break that limitation so only rooting will not give birth to any problem
And only unrooting will not cure any problem...
Its like
Opening your home lock will not make your fridge to stop working and locking your home again will not cure your fridge..
So the problem may be a faulty peace of software,
Any malware
Uncompatible firmware
Wrong governers
Or any tweak you made..
Try to find out what you have screwed up with that device!
we all should be polite enough to press thanks for anyone who helped US.
but how can i find that error ? can you please tell me any "test" or "check" to find the fault ? look, i'm very new to this android world, so can you help me by accurate and detail procedure ? please.. my phone is like a dead device now !

Okay there is no program that can "check" or "test" where the problem occurs with(just I'm saying, there is something wrong you did or wrong "procedures" you followed). All you gonna do now is state more details about the procedures you follow (i. e. where did you "get" the instruction, URL, etc.). /Where do you "think" you did something wrong (cause we cannot figure it out, it the procedure in solving a problem; knowing which is the problem to be solved and what caused that problem.)
Actually in my point of view here, your phone is not "bricked" cause it's still opening up, so we can still do something about it.

Look, why are you thinking about "root" "link" "procedure" "instrunctions" repeatedly. I have not done any procedure, i only rooted it and the instruction was from here, and that was appropriate insruction for x10 mini, and for your kind information, that was your previously recommended instruction too. But i think the problem is not that, even my device is not rooted, because the service centre guys updated the firmware.

No, I did not install anything.
And it is very bad for me, I can't do nothing against the problem. Now I notice that, when i start the camera, the device turns off !
Same problem
I'm facing the same problem. The phone switches off only when sim is inserted!
Could it be a hardware problem?? like Radio or battery! Please help!

[Q] Bought an used phone and don´t know what root.

Hi guys I am kind of new to this forum and really like all the website with so much information !
I am turning to you because because my friend wanted to buy an SGS 2 and bought one from some random guy whom he has no contact with.
The problem is now that the phone seems to be rooted because there is an yellow triangle that follows in the start up. I wonder if anyone knows how to see what kind of room is installed on the phone? I ask this because because the phone has been unlocked with the simunlock app but
the network connection is so bad, I´ve managed to make 1-2 calls to see that the phone works but i get max 1/5 bars in the connection barometer.
This made me think that maybe the root is bad performed by the guy that did flash the device from the begining.
If you guys have any kind of tweaks or ideas what to do I would really appreciate it.
I gathered some information that might help. This is taken from t he status menu in the galaxy S2.
Would it maybe help to restore everything to stock?

Sorry I choose the wrong section for my thread. Thanks to the MOD that moved it to the right one.
Root has no impact on signal strength.
But if you want to revert to stock, just download original firmware from http://sammobile.com/firmware, unpack and flash via Odin in PDA.

The ROM you use has no effect on your signal strength. The modem however, does. So you can try flashing a new modem if you're fine with the ROM besides the signal problems. ie.the UI, features offered, etc. Else you can flash your stock firmware for your region and that would solve your problem

Go to settings-wireless-mobile networks and in network mode check gsm only...if its on wcdma thats probably why u have poor signal
Sent from my GT-I9100 using xda app-developers app
Thanks a lot for the answers ! I´ve already tried to switch to gsm mode, dosn´t get any better. I will try to flash to a different modem but I have a few questions. Does it matter wich modem is current on my phone before i flash to another?
And if someone could point me in the right direction about wich modem I should use for my region, I live in sweden and use a swedish sim card and operator.

No.
For Sweden I think it will be I9100XXLQ6.
If you got the phone from a totally unknown person, i would suggest to revert it back to complete stock, and then start making all the changes you want from scratch, just to be 100% safe.
I agree i´ll flash everything back to stock and start from the begining, I think it´s the best way. But 19100XXLQ6 is the modem that my phone says I have, does that mean that I´am on stock baseband?`Otherwise if someone could show me a link or something for a step to step guide of how to restore everything back to stock.
Thanks a lot for your help guys !
Look backup your efs folder before you start pissi g about with stuff.
Then go to that link and get a 4.0.3 stock firmware for your region.
Then come back here and you can be advised about like siyah kernel/nand backups/roms.

Have you tried flashing a different modem. It might solve your problem. You can find flashable modem thread in the general section.

As to my experience, most of the problem arises due to uninstallation not done proplery. Because of this old files do not get erased from the memory and causes conflict.
I would advise you to use rom clean script and do a fresh install oof rom

[Q] Custom ROM after flash memory replacement?

Hi
I got my phone repaired by replacing the flash memory module, and been told that I should not upgrade it, factory reset it or anything like it - or it will not connect to the cell network.
Are these restrictions necessary?
I understand the modem is tied somehow to the flash memory, and should not be replaced. Will using cm-installer write a new modem or it should install a fully function cm11?
I couldn't find any existing answer since searching "flash memory" brings up results for "flash" as in ROM flashing ..
This is some kind of follow-up to http://forum.xda-developers.com/galaxy-s3/help/restore-to-stock-kies-flash-counter-t2760681
Thanks a lot. Using 4.4.3 is very important for me since they fixed a lot of the Bluetooth issues.
Cheers

Galaxy S9+ screen Jittering

Hey all, i wanted to ask if anyone is having the same problem as me.
So i bought a new Galaxy s9+ (G9650) and im experiencing some issues when slowly dragging my finger across the screen. It happens both in portrait mode and landscape. If i were to say... scroll across an image veeeery slowly or Play a game that requires fine accuracy (PUBG Mobile, its how i found the problem), the screen would start to jump around very slightly and repeatedly. If anyone has this problem or knows how to solve it please let me know. Thanks!
I will upload a video of the issue so you can see what i mean

Nope - Not an issue with my S9+
Did you make any changes in Developer Options for GPU Rendering etc?
Does this happen in all apps or just this game?

No, no changes in anything. I did not even have developer options enabled. i did read about it and tried them but no success. I have been using the OEM charger and cable and never used anything else to charge it. it also happens when in google chrome, maps, Quora, etc. The problem seems to get aggravated when i charge the phone. I'm losing my mind T.T such a beautiful phone with this problem. My latest whack at the problem is going to be a cache partition wipe. If that doesn't work im going all out and flashing a De-bloated firmware (Goodbye Knox and Samsung pay)

Sadly no luck, cache partition wiped but no problem is fixed. I am currently downloading 2 stock firmwares (i hope theyre de bloated) from dominican republic, one Orange and one from Claro. I would just go to samsung for their warranty but i do not have the original reciept because i did not buy the phone.
If i flash my own firmware (No root, downloaded from sammobile) will it void my warranty?

Rather than doing what you're talking about - Why not just Factory Reset? Backup everything you need or want using Smart Switch or move to your external sd card / computer.
To answer this question - Flashing the Stock Samsung Firmware with Odin will not void your warranty ?

I did factory reset. Installed all apps new and still got the problem. I paid 640USD for the device and now i have this crap, Its the latin american version (G9650).
Im currently downloading the Firmware as i said, i read somewhere about Product code changing while installing a firmware, would that be a sign to the warranters that someone messed with the device and would refuse to service my device? also, i read about Brazilian Firmware being closest to BTU (Bloatware free Android) but sammobile's link is not working ? Do you know someone with expertise in this area that could help?

Don't know if your device has an unlocked bootloader - If it doesn't - Then you can't really Flash anything that could void your warranty - Even if you don't change the CSC that shouldn't do anything to your warranty - it's Stock Samsung Firmware - Doesn't seem like you're too familiar with what you are trying to do - You might want to do some more reading & research ??

I know a thing or 2 (Just gotta catch up on some terms) ? Had an Honor 5 with Cyanogen and an S4 rooted and running AOSP. im just rying to be veeeeeeery cautious since i worked very hard for this phone and i dont wanna brick it or loose warranty. I really apreciate your input on this topic. I spoke with the previous phone owner to see if i could get a purchase reciept and bring it in for warranty repair, untill then i wont touch the phone. if all else fails, then im flashing De-bloated firmware and crying my phone to repair every time i use it ????. I have the worst of lucks ?
Is there a forum for newbies that explain all these terms? it would be nice for all them people trying to get the most out of their phones but arent very tech savvy.
