Solution for K750 After flash no network Here is the solution which the K750 after flash no network (This Phone Come before is 'Hang' and after flash become Please Wait and flash again become no network) what i did is 1. Select exact phone type - K750i, K750c or D750i. 2. Start the phone in recovery mode (via Force RSA recovery mode, CID=36). 3. Repair certificate and turn off the phone. 4. Reattach the phone in normal mode. It should be detected as brown CID36. 5. Unlock RSA incase the Repair EROM disable 6. Repair EROM. 7. Flash K750 full GDFS file. 8. Turn Off Phone 9. Reattach the phone. 10. Convert the phone to red CID36 using the special red CID36 EROM file: http://forum.gsmhosting.com/vbb/att...achmentid=26828 11. Turn off the phone and reattach it. It should be detected as red CID36 now. 12. Flash main firmware. 13. Unlock RSA and reattach. 14. Flash raw FS. 15. Upload singed archive (select the file example:K750i_CXC125953_APAC1_R1J002_Red36.ck75sfa 16. Reattach it again. 17. Customize FS by one of the built-in customizations. 18. Shutdown FS. 19. Reattach Again 20. In Tab "Security RSA" tick "Format Security zone" and "Recalculate CRCs" then "write to security zone" 21. If this show "ERROR: Could not initialize GDFS access" 22. Then In Tab "Locks" Convert to Brown and Use Direct Unlock 23. Put it sim card and wait for few seconds the Please Wait will run for short while and your phone is ready to use. ------------------------------------------------------------------------------------------------- See below More details |

Great work, Microstar :) Thanks for sharing this with us. |
after doing all that i got the phone on again and it shows network reception but it says sim inactive no matter which sim i put in...any solutions? |
Probably BARRED. Check with your operator. |
Quote:
yes you are right, its barred |
I Love This Solution Thanks A Lot4 This Solution |
can u show me where to get this file ? no link ! . Convert the phone to red CID36 using the special red CID36 EROM file: http://forum.gsmhosting.com/vbb/att...achmentid=26828 |
The file is built into the Cruiser Help File. Start->Programs->Cruiser->Help for Cruiser Then click on "Addition information" and "Special Files" Tada, click the link in the help file and IE will "download it" from the help file. |
tks for replying muppet, i found K750 red36 erom signed by brown 36 on our support. can i use this ? |
Still No network after 2 attempts following steps by Microstars here are the following files i use: 1st attempt: Version 4.30 used 1. Erom used "DB2010_Red36_EROM_signed_by_Brown36.erom2" 2. GDFS used"K750i(356xx-xx-xxxxxx-4)security zone(2005-0817.10.3857).mdc 3. Main used "K750i_CXC125952_EU1_R1J002_Red36.ck75sw" 4. Raw used "K750i_CXC125953_APAC1_R1J002_Red36.ck75fs" 5.

Need Help Tks |
Finally done and working on my 3rd attempt TKS to MicrostarGSM@ steps! Cruiser very good tool! :) :) |
hey sir microstar , u really made my day with this method , flashed 2 fones alright now . thank u buddy. |
Mr.MicrostarGSM@ u r very crazy man... this is stil very nice tnks tnks tnks.. %10000000000000 solved :) |
thanks microstargsm it worked well as you explained.. |
Quote:
can u tell me how did u solve it ? thanks |
yes, and if that "Could not initialize GDFS access" or "Failed" also a big problem too BR., Denis |
if the phone has no hardware failure, this method works 100%, tested on several phones already .... for GDFS problem, make sure you convert to brown, and lower your speed to 230000, 0r 115000 , and do the direct unlock/format Security Area ... |
Quote:
i will be follow this and try that today , yesterday i already test that red to convert to brown ,but can not , but i did not lower speed BR., |
today i follow this step , all of that is ok, but when i power on the phone, gud , the LCD is white only , then nothing ! BR., Denis |
does it vibrate when your press 'ON' ? try direct unlock again ... or, you will have to flash again, but don't have to repaet all thing, just flash arm+fs , and direct unlock it ~ |
i try that , but show me wihte screenshot, then unlock but same proeblem ! BR., Denis |
how about at w800??? the same procedure? BR BNC |
please help me.. i have a w800 no signal.. i have download the gdfs from support area.. but idon't know how to flash.. cause the file not in "mdc" another problem.. where to find the sfa file for w800? there is no file at support area.. thank u.. BR BnC |
flash using ARM flashing .... see the extension on the file?? similiar to ARM file?? then do it ... |
Trying to repair one with Usb-smart but no sucses. Any advice WBR |
my phone cant accept gdfs file.it gives fail end of the gdfs flash. how can i fix that problem? plzz help me.... my phone is cid brown36. |
Quote:
try to convert the CID brown to red ! BR., Denis |
ok i fixed my problem.i wrote gdfs file at Sonic.after that wrote full flash,customize fs,close fs,direct unlock.in this way phone ok with network :) thanx ur attention. |
thanks for share this solution. i need just 2 things: -how can i convert the phone to red CID36 using the special red CID36 EROM file. (step 10) the only way that i know how to convert is the change color buttom but dont give you any option to upload a file -can anyone send me the signed archive for w800 ( step 15) thanks a lot |
Quote:
while all the other steps i can do it normally. What do you think is the problem here. Thank you. |
I also have question about step Number 10 Converting to red, is it the same way that we do it normally from the SECURITY tap and choosing red Cid 36.... Please it's a serious matter. I already have 3 phones now with me the same problem. Any dead K750 i flash it's becoming please wait and after no network. The only original tool i have is cruiser. |
Quote:
flash with the Eerom file just follow the instruction |
Quote:
Can i know what is Eerom file and where can i get it for K750i to use with cruiser. Also the GDFS file in the support area K750i_FullGDFS_Brown36.ck75sw i don't know if it's the correct one. while if i want to flash GDFS file it's asking for .mdc file. |
The link for step 10 is not working. can someone help me with the link so i can know how to flash Eron please and where to get the file from? |
After a long search into the forum i foung my answers and files needed under this link: http:///vbb/attach...4&d=1119228389 I will try it and post result. hopefully i can fixe those 3 phones. Regards, |

you can download it at their support area for the files |
gdfs hi all, I have K750i that came in with problem : when allumination phone there was white screen for one second en then went dead. I flashed the phone with cruiser and then i got the problem of freezing on screen please wait. So then i did recalculate codes and write. Then phone booted normal without finding network. When i trie steps to repair this as explained here i have a problem with writing GDFS. This is what comes on the screen : RSA protection weakness type: PERMANENT Defeating RSA protection... Waiting for the phone to turn off... Should the communication hang, reinsert battery. Baudrate = 460800Bd Sending applet prologue... Sending applet body... Sending applet... Sending applet... Defeated! Sending CS applet... Initializing CS applet... Baudrate = 921600Bd Starting up GDFS service... Backing up GDFS security zone... Started writing to GDFS... Failed! Gdfs was downloaded from cruiser support, i allready tried to change baudrate or converting to red too. Nothing helped. Also can not download special erom file, it is in the help file yes, but when i click it nothing happens and i can not find the file on support from cruiser:mad: Please advice Thanks Daffy |
Here you go the eerom Quote:
|
You do not need this special erom files, all is in cruiser.exe (repaire erom, convering red/brown). First, it is time to start use cruiser v7.12 Foony |
Looking forward to revision history for that version :) |
Version 7.12 (22nd December 2005, beta version): Fixed EROM repair issue for brown CID49 K608. Updated W900i langpack info. Some changes to applet upload strategies. Added support for flashing CID54 phones (LG U8550) without using testpoint. RSA configuration analysis code slightly updated to reflect CID54-related changes. Increased robustness of RSA configuration analysis code to prevent potential crashes on invalid flash content. Added alternate method of replacing RSA certificates. Fixed one bug in low-level communication code. Fixed small bug in Repair certificate function. Fixed one previously introduced bug in GDFS access for P910. Updated K750i built-in customizations. Updated W800i built-in customizations. Updated TAC list for K300i, K700i, T290i, LG U8330 and Sharp V903SH. |
To microstar Thanks for the file but i allready repaired my K750i with gdfs and sonics cracked and my ufs box. After writing gdfs and unlock full network :) Thanks anyway Daffy |
Quote:
I was trying with sonic cracked and my ufsx box but i could not connect the phone. Can you tell me how you did it please? |
Nothing special i must say, just used cable ufs with dumy batt. connected my box, put in the gdfs K750 and pressed unlock/repair button. Don't know if this will help but sometimes when not connecting i release cable and dummy batt and reinsert but supose you tried that allready :) |
Quote:
Hi! tks for the solution, can i apply tis solution for the W800i phones as well? as i did try this by selecting K750i , but it didn't work and now always "Please Wait" , so pls inform me? WBR ReyTech. :confused: |
thanx solution worked 1000000000000000% good work thanx |
hi everyone i have a sony ericsson z520a. i flashed it. there is no network. i tried to upload another GDFS file from another z520a. it still doesn't work. please help. |
