Finally after a long spam of time permanent patching for A2 phones is out! Earlier it was jjpatcher which helped A2 users in patching but only for run-time which meant after a restart of phone all the values are restored back to normal which caused patches to be removed. Also it was unstable as the values which were in use were not used to get totally patched resulting in unstable functioning. But now you can have a patched A2 phone.
Required Downloads:
Click here to download whole archive containing all the tools required in below mentioned procedure.
UPDATE:Latest D-Ultimate unlocker is provided in above link. Now battery related problems are rectified. Tested by me!
Also you will need a registered account at Aerix. Registration is free. If you don’t have account yet CLICK HERE.
Archive contains the following files
- a2uploader.exe[a2tool]-necessary beacuse its the latest one
- aerix.exe
- D-Ultimate Unlocker Installer.exe
If your phone certificate is BROWN then skip to direct patching using A2 tool. If its RED then start from the beginning. You can check that by plugging in your phone to A2 tool and looking at the log. Please read further to know how to connect.
- Start Up Aerix & enter your registered account details by pressing the “settings” button.
- Press Unlock.
- Remove your battery and reinsert it.
- Connect holding 2+5 buttons down.
- Processing will start.
- As soon as it says “Restarting Phone” OR “Phone Restarts” in the log, etc. HIT ABORT!
- Aerix will then stop immediately and give 3-4 error messages in the log. Your phone is now blue. But we need brown to patch.

- Now, open up D-Ultimate Unlocker.
- Choose your phone, and tick Repair EROM/SEMCBOOT.
- Set certificate to BROWN.
- Select “No Lock Change”.
- Now connect your phone, holding 2+5 down once more.
- Wait until the entire process finishes.
Congratulations!!! Now your phone is ready to patch. Now we jump to how to patch the phone using A2 tool.
- Open A2 tool and in ‘MISC’ field browse for the .vkp patch you want.
- Now click on ‘E’ there, the patch’s coding will open in notepad.
- Add this line at the top in the beginning of the patch “;pAtChFiLe=/boot/phone_app.cxc” [without quotes]. Make sure that there is no spaces in it. May result in ACK error.
- Save the file and close the notepad
- Now click on Write script and connect the phone with ‘c‘ key pressed. If its your phone’s power button then use ‘2+5‘
- Sit back and relax. A2 Uploader takes a long time. Even with small patches. When a popup comes up click “NO”.
- After it says, “ELAPSED: xx secs.” it has ended, and you can unplug your phone.
Congratulations!!! You have successfully patched you a2 cid52 phone.
NOTE: Now even if you reflash the main your phone’s certificate will remain Brown.
To remove a patch at step 6 [when a popup comes up] click YES.
Method 2 : JDflasher CXC Patcher
When you have patched your phone with method one, you will find it quite long to apply one patch at one time which takes quite a long time. In a2 patching by applying patch we patch a file phone_app.cxc. By method one we apply one by one patch on it. By method 2 we can apply several patches in one time by using Far manager. We will be applying patch on the phone_app.cxc and upload it to phone to get patches working!
Before starting your phone needs to be in developer (Brown) state. For that follow 1 to 13 steps of method 1.
1. Get your phone’s firmware phone_app.cxc. Open a2 uploader and connect your phone holding ‘c’ key. Go to dir boot. There file named phone_app.cxc is there. Right click on it and click on read. Now a2 uploader will take few minutes to copy that file to your hard drive.
2. Download Far manager from here.
3. Now time to get far manager in action! On the left panel browse to place where phone_app.cxc is saved. Double click on it. Now the file is opened by far manager.

4. On right panel browse to the place where patches are saved. Now copy them to left panel. This is the time you can select several patches at a time and drag and copy them together. Right click on those patches which you wanna copy and drag them to left side.
5. When you have copied all the patches double click on two dots there on left panel. This will save the patches on phone_app.cxc.

6. Now upload the patched phone_app.cxc phone fs’ dir boot from where you copied it to your hard drive.
For more you can download video guide made by me from here to have a look at live action.
Congratulations! You have applied several patches at one time successfully on your a2 phone!
NOTE1: If your main gets cracked due to lot of patches or corrupt ones, you can remove the patch from phone_app.cxc by farmanager. Open the phone_app.cxc and delete the patch and save it again.
NOTE2: Also when you are adding new patches then apply new ones on the same phone_app.cxc on which you saved old patches.
Also thanks to Marzee_1 at Se-lifestyle forums!
Happy patching.
Bhuvan

That’s great, but sadly there’s no CID53 solution.
Oh, and one more thing: Blue certificate gets free stuff in Unlocker, so we can unlock + read codes FOR FREE in case we need to relock (warranty stuff).
Sorry for triple posting, but I can confirm it: Blue is totally free and you can read codes and instructions for using them (unlock/relock) – I tried them and works! So abuse Blue certificate and do what you want!

good
Hi blagus
I use W595 which I unlocked a couple of days back using A2 unlocking client. Later I was looking if there is some re-locking stuff on the internet just to make sure to re-lock it back in case I have to take it to the network operator when I have some problem – my phone is on a two-year contract. I didn’t manage to find anything useful regarding the re-locking thing. Your comment was interesting, Can you tell me how can I read the lock code so that I can re-lock my phone back. Thanx
Hi blagus
I attempted to read the codes with the Unlocker and it worked for my phone. I am able to re-lock now. I should have done this before posting the comment/question to bother you
dinnu3: I guess you converted it to blue with Aerix and read the codes.
Yes blagus, I did it the same way, converted it to blue with Aerix and then read out the codes with the Unlocker. It was really nice. Thanx for ur concern
I get error:

Bhuvan bhai need help. Yesterday when i was master resetting my C510, it struck in between and i left it for hours to complete but it wasn’t. So i thought to flash its firmware to HongKong version which i have downloaded b4. I tried firmware flashing but after all was finished i restarted my phone but it was showing a msg which is ‘configuration error contact your operator or service centre’. So it is in between. The firmware b4 flashing was CID52 but the HongKong version was CID53. Now what to to arm pls idols of out yaar. Thanks in advance. Shall i do firmware flashing with some different firmware? And is it necessary to use both .fbn and .mbn files together?
I got it……I updated firmware by flashing……..
I placed my CDA files after flashing and all went right..
Thanks for your tutorial guys……
Now I have HongKong version vch is for CID53 but I have CID52 phone , after flashing it is still showing CID52.
I want to learn abt CID please refer me a link for this….
Rajneesh, how could you flash CID53 FW to CID52 ? I don’t understand… you used A2uploader???!!!
blagus
Even I dont know ….:O
I had CID52 but I tried flashing its firmaware with a HongKong CID53 and it worked……:)
I’m using it, its working quite normal…..
And one more interesting thing is whenever I connect ma phone to a2 uploader it still says CID52 RED……….:P
I didn’t know what is this CID’s and all…..:P
yes I used a2 uploader….
aatishlp
u have to click there on no to apply the atch and yes to remove it!!!!
read the line again
zavana

look at mobilefree.ru!
or ask at our forum

Rajneesh Gadge
sorry man
was out of station!
akshay is also busy so no one was here
anyways
cid…its actually erom of ur phone which binds u from flashing or modding the phone!
simple
got various versions
for our a2 phone there are only 2!
cid52 and cid53!
cid52 users can patch there phone for free!
cid53 cant as a2 patching needs the color to be changed from RED to BROWN!
d locker charges for cid53 users!!!
but for cid52 no charge!
thats it
Rajneesh Gadge
http://www.topse.ru/firmwares/
i checked out here
there are 2 firmwares available for in 53 version for ur phone!
blagus
thats what!!!!
in jdflasher for earlier header error comes up!
dont know the same thing about a2 uploader!
Bhuvan
THanks again bro…….
OK, what’s important is that you patched your phone… but I still can’t understand how you put CID53 FW… Never mind, I’ll ask the_laser…
Rajneesh gadge
blagus
all right and let us also know!
Bhuvan & Blagus
Even I’m also surprised how it was……..:P
Rajneesh Gadge
so done with patching??
i am curious!
Bhuvan
Not yet tried patching…..[:(]
Bhuvan bhai I’m ok with turning it to brown but not able to patch my “phone_app.cxc” file yet…..coz I did’t find any patcher yet….
How to do that yaar???[:O]
Oh man, you need to go to mobilefree.ru, download patch for your phone (C510 R1GA026) -> find a patch, copy it and paste to notepad, then save it as vkp (example: type: patch.vkp), then click to button at MISC files in A2uploader, and click write script, and connect your phone. Then, when it says “click yes to…”, CLICK NO, then wait. After that, turn on your phone, and see if the phone behaves different in action which patch claims to change!
And one addon -> when you paste patch in notepad, at top add this text:
;pAtChFiLe=/boot/phone_app.cxc
then save………
blagus
Thanks a tonne bro…..
I’ll try and let you know what happened……
I have two more queries plz help me outta this confusion….
1) Is this true if we change (or Upgrade) main layout of our phone then Master Resetting has problem coz it happened with two time with me and one of ma friend….??
2) What this firmware thing has to do with the .vkp patches……I mean y I can’t apply patches of different firmware with ma firmware???
Sorry for my multiple queries……
Thanks in advance…I’m a n00b in patching friends……
Rajneesh Gadge
patcher???
what???
get any patch
and do the way its given here or tell me exact problem!
Rajneesh Gadge
ohh u meant compiling patch!
didnt got u
anyways blagus is way right
Rajneesh Gadge
for first query i really dont know!
i never faced that
for second one
patch variables are applied on the main part of ur firmware!
each main has specific values placed at specific places and diff if we jump to other!
patch’s value has got to match those!
thats why compatibility matter!
i hope u got it
Bhuvan Bhai

Rajneesh Gadge

@blagus & rajneesh
A2 Firmware is not CID or colour dependant. You can flash CID53 fw to a CID52 A2 phone without problems and will not change the actual CID of the phone. Same goes for colour: You can flash RED FW to BROWN phones with A2Uploader.
hello…
why aerix not confiirm my account????
or i need waiting for 24 hour???
Bhuvan
Bro that was a nice info.
Thanks.
I’m having a query mate.
Can we flash a firmware with .fbn file of some different firmware.
Same question for .mbn file.???
Plz also share meanings of the both, thanks in advance.
are_mean
there servers starts lagging some times
try again
Rajneesh Gadge
.mbn=main
.fbn=fs[filesystem]
like when we use a2 uploader to upload stuff we go to fs
when we patch/…we modify main
What’s mean unlock?
It’s able to patch CID53?
I’ve been reg. On aerix but won’t work,it have to cönnect to internet?
And…
We have to change cert.red to brown,if we want to patching cid53?
Bhuvan Mate:-
As you knw I have already unlocked n patched my C510 then What I’m supposed to do with the New Ultimate Unlocker mate???
I mean how to do that???
Afifth
unlock…if u dont know what it means then ur phone is unlocked!lol..no worries
still…few network providers lock the phone in such way that other sim will not work!
CID53…nope!i mean u can convert cid53 phone’s erom from red to brown for free yet!though u can patch!
means…half work can be done…
for aerix..yea internet is necessary!
like i said..yes!changing erom color is necessary!
Rajneesh Gadge
just start from the step when d-ultimate unlocker comes in action till its role ends!
nothing else
previous installed patches will remain at same place!
new one removes the battery bug..which was caused by old one to few people including me!
