More types
6600D
6600M
6600E6600I
6600H
6600R
6800..... etc.
Q5. What is NAND and NOR?
i)NOR:.Intel introduced the first commercial NOR type flash chip in 1988.NOR-based flash has long erase and write times, but provides full address and data buses, allowing random access to any memory location.
ii)NAND:.NAND is the 2nd type of flash . It has faster erase and write times, and requires a smaller chip area per cell .Tt also has up to ten times the endurance of NOR flash. However, the I/O interface of NAND flash does not provide a random-access external address bus. Rather, data must be read on a block-wise basis, with typical block sizes of hundreds to thousands of bits.
Q6. What is PSRAM?
A.Pseudo-Static Random Access Memory

Q26. I have a new double sim china phone but it show's insert sim on both sims?
A.Enable dual sim option in menu.
Q27. Where to find china phone codes?
A.here is the link Deposit Files
Q28. Where to find china phone pinouts?
A.All cable's pinouts for chines Mobiles
Q29. Where to find china phone Schematics?
A.All Chinese Models & Cloned Phones Schematics
Q30. I format the phone but it goes dead?

Use Correct address such as
Q31. What is the method now to Revive it?
A.Flash it with appropriate file.
Q32. My sigmatel got Flight mode when my child was playing with it.
A.
Dial *### Go to Factory Settings
now click on select type sensor at last
choose gekewei and press ok. confirm it ( press ok twice )
now you are ready to use camera
OR
Without sim type*#3646633#
then you wil get eng menu
choose option 5 misc
then choose option 6 assert testing
now menu will open
then select dual mode
Q33. My phone gets Handfree sign or earphone sign?
1.Wash handsfree jack with good solvent like petrol or CTC.
IF not solves then do as follows
2.Take Ohm-meter .
3.Attach it's one terminal to handsfree pins (one by one each) and other to different components throughout the board especially near to charging jack.
4. The points where the ohm-meter shows full reading or beep or Zero resistance proves that these are the components directly connected to hand free.
5.Once u discover those components ,check them ,change or replace.
Hope it resolve ur problem .
Q34. Phones is not showing MMC?
adjustment Fault b/w MMC and card socket.
Plz check Mmc door or it's respective jacket (may be due to bend pins).
