palagi akong tambay sa mga CM Flare/S100 na threads and 1 thing i noticed is main problem after mag palit ng custom rom at gustong tanggalin ay hindi na sila makabalik sa stock rom.. maski ako naexperience ko tong problem na to when i tried to install some custom rom and hindi ako happy..
Here's how you do it
Step 1. go to http://www.cherrymobile.com.ph/conte...e-update-flare
and download their v37 software update.. (you will have a zip file after doing this. DON'T EXTRACT!!)
Step 2.Copy the downloaded file msm7627a-ota-TBW592241_8572_V000037_mmc.zip to you external storage.. meaning memory card sa root directory.. dun ka mismo mag save sa sd card mo. root directory meaning sa main directory. hindi subdirectories.
Step 3.Shut down your phone.. and then go to recovery mode.. hold Volume UP and Power button pag nakita mo na ang red screen. release immediately.
Step 4.FORMAT DATA AND PARTITION
Step 5.select INSTALL FROM SD_CARD and hanapin mo ung nka save na .zip file from step 2. (USE ARROW UP AND DOWN TO NAVIGATE AND POWER BUTTON TO CONFIRM SELECTION)
Step 6. antayin lang matapos ang update.. SELECT REBOOT SYSTEM
Medyo matagal ang booting.. antayin lang after that go to Settings > Backup & Reset > Factory Data Reset > Reset Phone
Make sure to do factory reset after the upgrade para mawala lahat ng trace ng dating ROM na nilagay mo.. AND DONT USE CLOCKWORKMOD RECOVERY.. you'll get error
Update.. March 20, 2012
For those asking if pano kung naka ClockWorkMod Recovery and hindi maibalik sa stock recovery at hindi makapag flash ng stock rom.. ive found the solution
Follow the steps carefully
Step 1. Check your internal sd card for the drivers.zip file.. copy it and extract to anywhere in your computer.. (be sure to remember kung saan ilalagay ha)
Step 2. Now shutdown your phone.. go to fastboot recovery. hold POWER button + VOLUME UP if you see the green screen.. release immediately..
Step 3. Connect your phone. go to device manager of your computer and install the drivers(yung nasa step 1)
video for installing fastboot drivers
Step 4. After mainstall yung fastboot drivers. download AIO flasher.. (search search nlng po, wag magpa spoon feed, marami po jan nagkalat)
Step 5. Download Boot and Recovery image and System image and flash those images. (CREDITS to sir arunmcops of xda for the link)
video for using aio flasher
If you dont know how to flash using aio.. just search google on how to use it..
okay.. stock rom na ulit yan.. (just remember to do factory reset)
i will not be responsible if you brick your phone. flash with your own will
do not flash recovery image and then flash stock rom with your stock recovery, it will ruin your internal sd partition
it is advisable to flash stock rom when changing to other ROM
this will remove applications on your phone
this will not delete any of your files on your internal and external storage..
be sure to back up your applications if you dont want to reinstall them again..
just say thanks if natulungan kayo ng thread na to.

wala na po akong flare s100. sorry if di ko masagot mga questions niyo.. pero everything worked perfectly fine when i used this set up.. ang alam ko yung mga files jan gagana lang sa mga old units. dun sa mga bagong versions alam ko di talaga pwedeng iflash to..
