[Q] Ace II i8160, startup error always with all new roms

Hello and happy new year ,
Οver three months I try to flash my mobile and always writes me the same error "unfortunately, samsung setupwizard has stopped" . Τhe device always hangs at the point where I choose system language on screen. To be able to work on my device should I have make it "flash" with version of android 2.3.6. Ι have tried to do "flash" with roms too, "pac-rom android 4.2.2" and "10.2 cyanogenmod", and always my device hangs at the point of the loading logo. I've done "flash" with these roms , as stated above, in my friend's phones ,same as mine, and has been correctly installed. The devices are not stuck like mine and working properly. Why my device is not working properly as the other? I am disappointed . I would like to help me :crying:

Try to wipe data/factory reset in CWM after you install new ROM. But you have to know that you lost all of your data.

As far as I understand, you are on GB 2.3.6 ? :confusing:
If this is the case, flash Jelly Bean 4.1.2 then you could flash Customs ROMS based on 4.x

I've done it several times what you're saying. The error message is always the same when the device become "flash" with the version 4.1.2. A friend who is technical in Mobile phones, IPHONE, HTC told me, that should be reprogram the motherboard or replace. If this is the only way, then we are talking about 100 euro cost. He said that, because the device does not show the serial number and the baseband has this "ΧΧΧΧ". I do not know if anyone here on the site also has solved a similar problem without changing the motherboard

You must flash 3-part firmware (PIT + CODE/PDA + CSC) when switching between 2.x and 4.x!
(Google MB4.zip for the to 4.x conversion)

Install Odin and USB drivers, extract mb4.zip (http://d-h.st/6QB) until you get .pit, CODE and CSC files.
Open Odin, load the 3 files (CODE goes into PDA), reboot your phone in download mode (hold volume-, home and power until you get a yellow triangle then press volume+ then connect cable to PC), click start in Odin and let it work, after it boots to "Samsung Galaxy, choose your language" reboot into recovery, open the CWM zip, wipe data/cache then flash the rom you want

I knew pretty much everything that you say. Unfortunately, my friend, every time a file is missing me. This file is the modem file for this mobile, where fixes the baseband.This file I have not ever found in no one zip file. Can you find it for me, I should be grateful to you .

Is it a P? a L? a Chinese/HK model?
(Unluckily I don't know those variants well, you'll have to extract various firmwares until you see one with modem.bin.md5 and ipl.bin.md5 then flash those 2 files...)

The firmware means "rom" or is it something else?

The .md5 file you get when you download and extract stock firmware..

You can't flash single images with Odin (well, maybe if you wrap them back in a .tar) or just use Heimdall

Anyway , I have sent my device to the Samsung service and they will replace my phone's board. Thanks everyone for your advice.

I assume you did not install a custom recovery???
If you did you need to download the right firmware package and load from the recovery.
You may try Odin 3.7 if you can manage to get into stock firmware upload.

Its not bricked - your recovery is probably a cwm - flash twerp if you want to install cm11 - or stock recovery..anyway cm11 is great but no phone...so not great for us 5100

Thw note cannot be detected anymore in pc. How do I flash or root again :3

Download and install Odin 1.85 next search the stock firmware for your model here http://www.sammobile.com/firmwares/
Get your Note into download mode ( Press and keep holding the Volume Down, Home and Power ) and connect it to your PC, Odin should "see" it the first slot under ID:slot should turn a different color if so you are in good shape, now put the Firmware you download from above mentioned site click PDA*button and select the downloaded .tar.md5 file, Important: In Odin, make sure Auto Reboot and F. Reset Time options are enabled. Also, ensure that the Re-partition checkbox is not enabled and hit start and let Odin do the rest and you should be up and running in no time and now you can start over from scratch

[Q] SM-P600 Bricked (no recovery)

Hi,
SM-P600 without ROM, without recovery, Kies and Odin doesn't work.
How can I reflash stock ROM or CM12 rom ?
Device : SM-P600 (with samsung rom stock 4.4!?)
I root my tablet with odin and teamwin 2.8.0.0 (PDA field + tar file)
the root flash should success.
I restart in recovery and install custom rom CM12 + Gapp
the tablet restart and stay to CM12 loading during all the night.
I come back into recevery mode
I try to wipe cache/dalvik => unable to mount cache/dalvik
I try to wipe cache => unable to mount cache
I try to wipe system => unable to mount system
I install Kies on my computer and try to restore the official rom with it.
The download of the rom is ok and Kies try to send the rom to the table a transfer is running during 15min (progress bar into computer windows, but no progress bar into tablet).
After that a second transfer progress bar into computer stay to 0% during 1 hour. I unplug my tablet.
Now I have got a table without recovery. I have access to download mode.
But I cannot transfer stock rom (PDA field) with Odin.
Thx for your help.
Staying at your disposal

I can flash recovery mod (TeamWin) with Odin.
But I cannot send Kies tar file by Odin.
I am downloading old stock rom (*tar) to transfer by Odin 3.09
How can I convert a CM12 zip file in tar file to tranfer it (I haven't SD card)

You could use a USB OTG cable (micro USB plug on one end and a socket like the USB ones on a computer on the other), one of these:
http://m.ebay.com.au/itm/301542874539?nav=SEARCH
And use it to plug a USB stick with the zip file on it into your tablet. You would have to mount it in twrp before flashing the zip.
They are a very useful cable to have, if your screen breaks and touch doesn't work you can use it to plug a mouse into the android device and use that for things like backing up your data before repair or disposal.

Hi Dribounet
I have similar issue with my SM-P600.
I have tried 10 official roms , official and custom recoveries also , without success. I am absolutely sure that I am not following correctly the procedure using Odin and its version or combination of this plus wrong official ROM and so on.
Also have tried to use PIT file because I think something goes wrong with the partitions but not success again,
Would you advice with your steps you follow in order to succeed installing custom recovery.
Can I install only the recovery without ROM and how I can run in it ( button combinations)
For now I am just able to run in Download mode and with one official ROM to run the process to the middle- then goes in error with Odin and when reboot the device it shows message "Firmware upgrade encountered an issue ..... "
Thanks in advance for all answers

[Q] Nand write fail for rom flash SM-T805

Hi, I am in need of assistance. I have a Tab S 10.5 SM-T805 with rom XXU1ANF8
I am struggling to flash firmware for my sm-t805 using odin and stock roms downloaded from sammobile. I have tried various version of the stock roms as well as different versions of odin, but they all have the same result.
The result is either "NAND Write Start! FAIL!!" or "Setup connection.. Can't open the serial(COM) port." The order in which I do things might impact which error I receive, such as attaching the tablet first or selecting the ROM file first in PDA box.
Here is why I am desperate. Since this result was pretty consistent, I flashed TWRP successfully and wiped all the partitions, including the system partition. Now, there is no OS installed. Using TWRP I have attempted the 'Install' method of flashing ROMS, but now my error is exclusively the first type.
I read some of the other threads and attempted any advice relevant posted there. This is sort of relevant to what I am trying to do, but my system partition has been wiped. (http://forum.xda-developers.com/galaxy-tab-s/help/odin-flashes-fail-t3028264), so there is no relevance to enabling USB debugging for disabling reactivation lock. This is a guy who can do what I am trying to do. (http://forum.xda-developers.com/galaxy-tab-s/help/roms-flashing-advice-t805-t3031963)

Is activation lock off? That what causes it not to flash. The only thing I can suggest is transferring a custom zip rom and flash it with twrp. Or try another firmware from a different country.

It was my observation that this activation lock is off by default on the stock rom. In order to turn this on, you have to register with a Samsung account.

Idk then, I guess you got to wait for another firmware that comes to your country

Just flash the Swiss Rom then after it fails, boot into download mode again then Install and boot into twrp.
Twrp will wipe the cache and auto reboot. The device should then boot normally.

Is TWRP 2.8.6.0 chagallwifi ok for this procedur ? and can i flash the original swisscom ? or the cleared .tar without the two files ..... and when i in download mode ... wich kombo can i use for reboot in download mode again

Pardon Me.. But I'm a newbie... Custom ROM suggestions required...

Hi ,
I am new here.. not new to rooting ....
I used to use my Samsung galaxy grand i9082 but switched to nexus 5 last year...
Since then my grand has been sitting in my cupboard drawer. I also found this phone very slow performance so switched...
But now i am thinking of flashing a custon Rom to increase its performance and remove all the bloatware...
so i need suggestions of a stable custom ROM with good performance and all features working like dual sim ...etc..
Can you guys help me .... ?
Lollipop or Kitkat or Marshmellow expected with fast perfomance and no lagging ( I guess Marshmellow will lag too much so i can go with KK or Lollipop...)
Please suggest me ...

First of all i cant find any download link for CWM recovery for i9082...( .tar file which can be flashed using odin.. ihave the zip file with name CWM_6.0.5.0_Non_Touch_xenon92.zip )
As of now i have downloaded TWRP recovery i9082_TWRP_skullface.tar which is flashed successfully using odin3 v3.07.
but when i restart the device after booting into android it again shows android recovery ...
I also tried the unchecking the auto reboot in odin and removing battery after flashing and trying to boot into recovery but again no result ..everytime the samsung logo comes and again phone restarts and same goes again and again till i boot into the android.
Can anyone give me the CWM recovery...thanks in advance....

Try this rom: http://forum.xda-developers.com/showthread.php?t=3073108
That is a CM 12.1 port to grand duos by pawitp. It is pretty stable and functional. Though I experienced frequent freezing with the latest build 20151115, I got it fixed by installing frost kernel ( here: http://forum.xda-developers.com/showthread.php?t=2927449).
After installing frost kernel, adjust your cpu governor to lulzactive, and your i/o scheduler to sioplus (the most recommended setting for Grand duos with CM 12.1).
Though the consequences of using custom kernel with that rom is that you can no longer uses delta upgrade features of that rom, you have to download full update build and flash it as if you're to flash new rom (though without wiping cache partition and dalvik cache).
Good luck with your quest to find perfect rom for your grand duos!
