Fail: Preserve Calibration fail (cannot find nv item in nv) What does it mean? I just made up the PAC file with NV = mtd6.backupfixnv.yaffs2.img extracted from other phone (same model). This is what was supposed to be done isn't it? Is the error saying that I got a wrong nvitem file or something? I couldn't extract nvitem.bin file so I just pointed it to the mtd6.backupfixnv.yaffs2.img file. Thanks ...  

Good Guide! All steps are described clearly... But in the case of Spredtrum YXTEL G926 (Clone of Galaxy Ace) we have to UNCHECK all the items in Calibration Tab also.... :victory:

Ravage32 said: How To Use Research Download! Hey all! I was looking around the web and i didn't seem able to find a actually proper tutorial on how to use research download for flashing phones and such. It not necessarily difficult it just took me a while to figure out how to use when i first started using it so i thought I'd make a tutorial for anyone who doesn't know it Glossary Flash: To overwrite your phones existing software with another. Rom: Firmware for your phone. .pac file: File in which research download uses. Before this it is important to have the VCOM drivers for you phone installed on your computer. (Links Below) To start go ahead and press the first gear button. This will open up a browse menu Use the menu to browse for where your .pac file for your phone is saved. These files are usually given from the phones manufacture. The browse menu can only open .pac files. Once the file is loaded you can tell, you will be able to see the name on the bar (as shown). Next press the second gear to open up the settings menu. 1. How much to port (self explanatory) 2. Bautrate. Leave this at 115200 unless your phone manufacture said otherwise. This works for the SC6820. 3. This will be automatically selected once you load the .pac file. 4. Where all the files are stored. You can actually extract these once you load a .pac file hehe . 5. Name of Each file. If its ticked it will be flashed. You can untick things you don't want to be flashed. 6. This is just if your going to build a .pac file from parts, don't worry about it that's a whole other thing. Once your don't editing the settings you can go ahead and press Ok. After your done press the arrow like button. This will start the process and have it ready for your phone. Take the battery out of your phone now for at least 15 seconds. Place it back and plug in the usb while simultaneously holding the volume down button. You should see in research download that it has started flashing! ( You can let go of the volume key now ) When it is finished just press the stop button and disconnect your phone! :victory: Feel free to ask questions, but PLEASE don't quote this whole thing.

There should be a .pac file in order to flash this but in the rom package i can't find any, only a .p5c file. Tried to extract all the files inside in order to create a .pac file as mentioned above, but i can't find 1-2 .img files that are needed for packaging and the result is an error when trying to load the packet file.

Pressed Play Button And connected my device.. but no any progress shown in Research download..plz help..  

Make sure you have ALL the drivers installed correctly and that when u first connect it its showing up as somthing like "Spreadtrum phone" connected in your new devices popups. Probably good to restart the computer after you install the drivers. Are you using 64 or 32 bit? Ive had lots of troubles lately with 64bit windows 8 because drivers would not install because of signature verification. Works better on windows 7.
