i forgot to say, that i wanted to install a new costum rom, but it failed, and when i flashed back, it happend (

now sometimes my bluetooth turns on, but i cannot find any devices, and they don´t find me

do you think, its a hardware error, because i flashed back a couple of times now. the best thing is my guarantee is no away, because i flashed custem roms

[Q] please please understand and help..

I have rooted my phone with odin and installe the kitchen pro app, but whe i try to install checkrom 6hd or any rom it fails at verification i successfully did all this a few months ago on a sgs2 before it was stolen, i now i seem to be hitting problem after problem...........
if you want to refer me to ''in in this thread'' please post the link because im struggling to find help, ive looked all over and navigating this site is far from easy.
I get the yellow triangle so i guessi rooted properly, ive tried 2 roms, neither will install :9 please help me............ delete this thread after if need be
again, please help
which kernel are you using.. download a custom kernel..like siya or neak.. and make sure its the correct version .. dat is if you are using GB rom then download a GB kernel. the try flashing the rom from recovery
1) Kitchen pro will work only after installing Checkrom,
2) flash another (CWM+Rooting) kerenel from ODIN like siyah,
link for GB Shiyah Kernel : http://gokhanmoral.desean.net/siyahkernel/v2.6/Siyah-v2.6.14.tar (make sure you are on GB version now, otherwise you have to select ICS siyah kernel)
and try to install Checkrom from CWM
I've done all that, I keep getting E:verification failed.... any help please?

Few Questions guys

Ok so i am noob with Samsung and dealing with flashing and all these stuff, i just switched from iPhone to Galaxy S3 GT-I9300, i have read so many posts and watched so many videos, all what i want is some clarification
1* I have managed to download CM 9.0.0 for my phone and installed it through ROM Manager , i have noticed that my Data service is not working, am living in Kuwait "Middle East" the wifi is working fine no issues and i enabled the Data Service through the settings, how can i fix the issues with the data plan although it is working fine after i restored to my stock ROM
2*Can u tell me what the use of the Odin except rooting and installing a stock Firmware ?
3* correct me if i am wrong but the ROM will only do some sort of interface for the phone , as we say in IT "GUI" of course not to forget to mention the speed and tweaks for hardware of the device it self, i mean it is not a complete OS "Firmware" mostly GUI with Tweaks.
4*While doing the installation of the ROM and remove it and getting back to my stock ROM , nothing from my data has been changed, does that means every time i install any ROM and get back to the old one my data will not be effected on the stock ROM?
5* what would happen if i tried to install a ROM not compatible with the firmware i have ? and how would i fix that ?
6*How can i tell if the ROM is compatible with the firmware i have? , for example in my case i downloaded CM 9.0.0 for my S3 which has 4.0.4 firmware
7* I have understand that the ROM must be compatible with my phone version , what i mean with version like International version or US carriers versions, am i Right?
Am sorry asking too many questions,I tried my best to make the questions with yes or no answer, and incase you would like to write more please do
answering me those questions will help me alot, i have been reading so many posts and it is making me go insane
Thanks so much in advance :angel:

1. try reboot
2 thats about all its for
3............
4 all your data will be there unles you do a full wipe in recovery which is recomended before installing any ROM.
5 A ROM isnt specific to your firmware.If you have an international version which is GT I9300 Or GT I9300T any ROM from the I9300 threads will work. Dont flash anything made for the non international versions

You do a full wipe. A full wipe is always recommended to prevent some weird bugs.

What Rom/Kernel were you experiencing this issue on?
A clean wipe/install of a rom usually fixes most issues.

I also rebooted several times but my wifi still says error. I looked for a stock kernel.sin flashed it the wifi is still not working so after flashing the kernel.sin i then tried a hard reset. Now my question if i reinstall 2.3.4 is that the only way il be able to get my wifi working again or isn't there a shorter method because im sure if i reinstall the phones firmware that should get my wifi working again any ideas ? by the way i havn't installed any custom rom i was about to but the wifi issue is a problem

[Q] Mobile Network not available after Flashing to custom ROM

Hi guys,
This is my first time posting a thread in here. I need your help.
My phone is Samsung Galaxy S2 i9100.
Baseband version: I9100XXKI3
(screenshots attached for more info)
I rooted my phone By using Odin3-v1.85. and flashed the recovery to cwm 5.x (i can't remember version) and tried to install custom ROM OMNI
(omni-5.0.2).
I accidently downloaded and installed OMNI for i9100G version. But my phone is i1900 version.
(I downloaded this omni-5.0.2-20141222-i9100g-HOMEMADE.zip ). i forgot to backup previous ROM .
Then i was unable to Turn ON my phone because every time i turn it on, it come back to recovery it self (it's a bootloop i think).:crying::crying:
then i flashed the recovery to CWM-KitKatCompatible-i9100 (version 6.0.2.7) and installed custom ROMs and tried (PACMAN,CM,AICP).
It works fine. everything is just perfect. But i can't make calls or receive.
It says "Mobile Network not available". when i call my phone from another phone i hear ringing it. But nothing shows in my phone. after few seconds i got a Missed call Alert. But this happens only sometimes. All the other times. i cannot call it from another phone.
I tried reset and flash modem using CWM as well as from odin. but no luck.
Please Friends Help me. I don't know whether i put this thread to right section or not. sorry about that.
I did all of these things by surfing XDA forum (as a Guest). And i'm happy about what you guys are doing. Keep it up.:good::good:
(sorry for bad english)
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

I reflashed to stock rom and it's working fine.
But i tried to install custom Rom again but no luck there. I was again stuck with Mobile network problem.
May be the problem with kernal.

You will have to flash stock 4.1.2 rom or try a 4.1.2 custom rom. The problem may be caused by the drivers in the built in kernels but I'm not completely sure.
No mobile network on custom roms
I have already flashed the 4.1.2 jellybean rom but 4.1.2 rom also havr bugs. Lock screen doesn't work, I had tried hard resetting but it doesn't solve the problem. I Want use 5.0.2 hazy , cynogenmod, pacman , dirty unicorn, etc and other many custom roms but I'm facing same problem no mobile network, other than that everything work fine....

You mean stock 4.1.2 rom? That's very weird for a 4.1.2 stock rom. Maybe an android 4.2 or 4.3 rom?
You are saying that I should try 4.2 or 4.3 custom rom??

Yep.
I am having same problem with the network connectivity. It happens with all custom ROMs that aren't stock based. I am stuck with Chameleon ROM which is a hybrid and has a stock samsung base. It is a great ROM but is outdated. I would like to upgrade. Any solution to this problem is welcomed. = D
Okay I think I got a solution here. The procedure is:
1) Make sure you are on a stock based ROM or other ROM where your network is working.
2) Backup EFS.
3) Flash custom ROM of your choice.
4) Restore EFS if there is no network.
Done.
To restore efs, you can use any app tailored to do so but for me it didn't work. I followed this thread:
http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021
Follow the steps carefully and you will have network in any ROM you like. Hit thanks if helped.
PS: Sorry for double post
EDIT 2: Even though my network is back, which confirms that the problem was with the missing IMEI. I found out that the IMEI I got now is a fake one. Got to get the real one back now..
i did flash android 10 in my moto one power
after that i went back to stock rom but noe netwrok is not showing up
