Nokia N900 is Amazing tablet phone ever made over the century
i know that u will say : so whats new about this

what i would say that from about 4 to 5 years i bought n900 when it realse in lebanon for about 600$ and it was great phone, the story begin from about 1 year after many and many flashing install unistall app when it begin to interrupt phone call and droped it after this it begin to popup our known msg "All telephony functions, including emergency calls, are disabled due to a communication error. To recover, you might have to reboot the device" with a Red Line through the SIM Card icon on the home screen, reboot after reboot flash after flash with no luck, beleive me i tried all the method that has been given on google even the last one with the hummer nb: (if u want to n900 to back to life u will do more than this ) even i read about someone wash his board and other method that u have to put another useless sim card on card holder i put one and two down the battery above the card holder, went to repair shop to fix if it a hardware problem immediatly they look to the imei and said that ur phone cannot be repair cause need for flash room blah blah blah...
the problem is related to the pins that touch the sim card that what must said about the problem and it a hardware problem
so .. after many abuse words to nokia and about their phones and i Borrowed china phone to use i saw that nitdroid has came to a stage that it can installed on EMMC (Internel memory), before i didnt want to spend any more money on not working phone so i installed it and try it we will talk later about heating and other problems.
when i upgrade to latest version RX-51_2009SE_21.2011.38-1_PR_COMBINED_MR0_ARM i use global firmware not my mea (middle east version) .
when i'm fetching navifarm to flash my brother phone nokia 5530 with anna belle custom firmware i fitched to n900 firmware and saw there my Product code 0582647 RX-51 MENA i downloaded it to try one more time with a little hope .
so i flashes my phone with this firmware that meet my Product code and then i installed nidroid n12 u may with repartioning the EMMC.
i dont know what is the problem really and iam not sure if my n900 go madness but what i know that its working from 2 days without red line and telephony funcution disabled even not droping any call maybe the firmware and maybe when i repation the emmc it refresh the flash memory again now i'm use my n900 try not to reflash again hope to last longer .

to try my method please follow this steps :

what u need:
1-RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin
2-latest firmware RX-51_2009SE_21.2011.38 with ur phone code get it from Navifarm
3-maemo_flasher-3.5_2.5.2.2.exe
4-Nemesis Service Suite to get ur product code google it
5-libusb-win32 to flash on x64 platform google it

before u begin i suggest to install nitdroid first on emmc there is a simple guide with repationing EMMC on the wiki to avoid u flash many time
