[Q] Reverting to stock Samsung FW from Kyrillos V7.5

Hi,
Although this is my 1st post, i've been reading posts from this forum for quite sometime now.
Now, I've basically flashed several official FW upgrades from SAMFirmware on my phone and quite recently, i've flashed Kyrillos V7 then 7.5 on my phone. I've been pretty happy with those but unfortunately, i have to revert it back to the official firmwares due to warranty issues (i.e., my phone developed some problems with the capacitive screen...since my phone is still under warranty, i'm planning to send it back).
I tried flashing back the official firmwares that i've flashed before but now, my phone won't boot. It get's stuck on the flashing Samsung text during bootup.
Is it not possible to flash back the official FWs from a Kyrillos V7.5 FW? If it is possible, am i missing some step? Any advice would greatly be appreciated.

it's possible.......u can reflash to get the job successfully done.
Try reflashing again with the same stock FW.

Reflashing again should do the trick.

If you stuck in boot animation, reboot in recovery and wipe data! This happens to me after reflashing from custom to stock rom!
Aftew wipe, stock rom work normaly!

First flash with 2.1 and than with 2.2...
Sent from my GT-I5801 using XDA App

hi i am able to flash 2.1 but unable to flash 2.2 after installing kyrillos... its showing "dev/stl7 "cant mount something like that before boot screen arrives and stuck there ..

I had the same problem. Try to flash original kernel. Somewhere there is a downloadable

[Q] Bricked. Something goes wrong with ICS rom

Hi! Im new here but only in number of posts. Ive been reading this forum for some time now.
My problem is that my defy goes only in stock bootloader (i think i did something wrong with recovery after i flash ics rom). My CWM does not work. I tried RSD Lite but 2.1 rom does not work (bootloop). Maybe i should use 2.2 rom (i have flashed froyo kernel).
I feel like noob now...
Pls answare if someone knows what to do...
I must mencioned that ics worked but than i've installed CWM (i thought that it is uninstalled) and reboot, than the phone bricked...

Instal the froyo sbf for your location. If you only have official eclair (some countries in Latin America I think) just flash that if you have never flashed an froyo sbf. That way you can keep warranty. Afterward wipe(factory reset) in the stock recovery.

That is what i did... by the mistake i downloaded wrong spf... my phone got crazy... than i downloadaded good spf but i didnt wipe factory... still phone was crazy but than i read yours post and i realized how stupid i was... all now is really good! thank you!!!!!!

2.3.6 vito

Hi guys
I flashed the brazil vito rom, and know ive got stuck.
Is there at moment a way to downgrade this version?
Or is there a other rom i may could flash with my 2.3.6 vito.
Couse ratail is not woking. By the way someone know why?
Im sorry about may bad english...

"Couse ratail is not woking. "
This is so much general - please specify your problem in more details - are you getting any error message or how the phone behave?
"Is there at moment a way to downgrade this version?"
Take a look at here http://forum.xda-developers.com/showthread.php?t=1497263
"Or is there a other rom i may could flash with my 2.3.6 vito."
Yes. All custom ROMs, that works with GB - tezet's CM9, Endless7's CM7, Argen2Stone, MS2Ginger... in fact all roms, except MIUI and stock froyo (but you can downgrade now and use these too)

Actually, it's not possible yet, the Vivo ROM (I'm guessing Vito was a typo) can't be rooted and, right now, it's not possible to install any custom ROMs or downgrade.

Can't he just flash SBF of another GB ROM, which is rootable? (UK/Brazilian/China etc.)

No, the Vivo ROM has v4 BL, and the other GB official ROMs have v3 BL. I'm not sure why it doesn't work, but nobody in the forum reported success in rooting / downgrading (or even changing to another official GB) from Vivo and Personal ROMs.

Okay thanks for the fast answers i thought, too that this is because of the new rom.
So the ratail 2.3.6 has no v4bl, too so i cant flash the sbf, too?
So its normal, that i cant flash any other sbf? Or are their other roms with v4bl?
And do you think there will be found a way to root/downgrade this version, or is it impossible?

Yes, the 2.3.6 has v3 BL, unfortunately you're stuck in the Vivo rom for now. If you try to apply a different SBF, your phone won't boot, and you'll have to reaply Vivo rom to use the phone. For now, you can't change ROMs either.
All we have now is hope that it'll be possible to root and downgrade this version, I'm sure a solution will appear sometime, we just have to wait.

Are there any news? Do someone know?

Someone know where i can find some informatian?

Unfortunately, there's nothing new yet... All we need is hope.

Are there any news about this issues?

Downgrade ICS CM9 back to GB 2.3.6

I´ve recently installed CM9 in my Milestone 2, but the general bugs made me change my mind. But, after trying every possible rom with 2.3.6 firmwares, I haven´t succeded in any of them. The only one working here is the Personal SBF, here from xda > http://and-developers.com/sbf:milestone2. After every installation, my phone gets stucked in black screens without recovery. RSD Lite can read it, though, so I can always install Personal SBF, root with these instructions - http://forum.xda-developers.com/showthread.php?t=1750277 - and go back to ICS from there. But it´s very weird.
Bottom line: Milestone 2 accepts Persona SBF LATAM with 2.3.6 and CM9. But will not downgrade to any other 2.3.6 rom nor can accept any MIUI version. It gets stuck in black screens without loading.
Sorry for my poor english. I´m not used to write in this language, but this seems the right place to ask for help.

2.3.6 firmwares are not downgradeable, so you can't go back to froyo if that's what you're trying, you should be able to successfully flash any of the 2.3.6 R01 firmwares such as personal or retail latam...

Same thing happened to me. You will have to install stock GB rom by flashing it with RSDLite.

Tried stock (retail) from Brazil with no success. Weird. Was with Vivo sbf installed, no root. Than I´ve managed to root and install ICS. Now I´m trying to go back to some other rom with 2.3.6, but no one is working. Nor retail, nor tim, nor vivo, nor custom. Only ICS CM9 and Personal 2.3.6.
Am I missing something? I´ve followed the right procedures to upgrade, and follow the right instructions when trying other roms. But I´m almost giving up and leaving ICS installed. At least I´ll have no Blur or bloatware in my phone.

That is probably your problem. Using the Persona and Vivo rom. Check here: http://forum.xda-developers.com/showthread.php?t=1497263
It says it's not possible to downgrade if you have those ROM installed. I was using UK GB ROM so I was able to downgrade to CM7/CM9.

2.3.6 personal is R01 which is newer than 2.3.6 brazil retail, you can't downgrade R01 or R02 firmwares, I mean you can't go back from 2.3.6 personal to 2.3.6 Retail Brazil, you can only flash R01 or R02 firmwares on your phone (Personal, Claro, Movistar, Retail Latam)
Try Retail Latam which is rootable and the less bloated of the R01 firmwares:
Retail Latin American M2L_U6_4.5.2_51-27_R01_SIGNED_US1MILA2GBRETLAB125LA003.0R_STABLE45LAMILETRETLA_P005_A028_M001_HWp2a_Service1FF.sbf.gz

Worked ^^
I wonder if I´ll be able to install CM7 from this rom.

Ajit,
A few questions
Is it a Defy or a Defy plus?
What is the name of the SBF that you flashed via RSD lite.
9.10 is not the boot loader version.I am assuming you are probably on BL7 (boot loader)and the SBF that you are trying to flash is a lower boot loader version . This happened to me when i flashed a Defy plus SBF on my Defy and then tried to downgrade just to find out that there was no returning back (as of today).
Here are the steps that i followed to get my phone working and i sincerely hope this may help you as well :
1) If you are on Defy plus (MB526) you can try flashing the rom mentioned in this post http://forum.xda-developers.com/showthread.php?t=1595013. It will also help you to get a rooted device.
The above step should get you a working phone ,however if your device is a Defy (as you mentioned in the OP) you will end up having a non functional camera and experience battery drains.
In order to rectify this you can download this awesome rom from Quarx from the following URL http://quarx2k.ru/cm10-2ndboot-nightly-defy(+)/ (CM10-20121018-NIGHTLY-mb526.zip is the one that you should be downloading)and apply then the V3 update.
Your phone should now be running an awesome Jelly Bean based rom with everything working perfectly (well almost its still a Nightly Build)
The steps mentioned above is what got me a working phone and there could be other ways as well . This is a wonderful forum and i am sure that experts will help you in getting your problem resolved.:good:

I understand that at this point you are stuck at bootloader error message that you have mentioned in the title of this post. Connect your device to a PC and flash the SBF(stock defy rom) that you can download from the link below using RSD . Once RSD lite shows the status as "Finished" , you should then be able to boot normally. Hope this helps.
