A classmate of my son has a bricked GPS 4.2 (YP-GI1CW/XEN). Another classmate tried to root it. But it got wrong.
By reading and searching guides here, i have rooted some htc phones and succesfully tried several roms, so i offered to take a look.
I did not know this player before and i dont know what happened to it. The only think my son has heard is: someone rooted it, installed a rom, made it empty again, searched for the right software (rom), but could not find it.
When we got the phone it only showed the logo of galaxy S2. There is no sd-card inside.
I spend hours of reading, finding the download mode (3-button), odin, heimdall, kies etc.
Tried everything, but can't get it done
Could anyone please help me?
Download method works
The 3-button method works and gets the player in download mode.
Info on screen: (WITHOUT usb connection!)
Product name: YP-GI1
Custom binary download: yes (13 counts)
Current binary: custom
do not turn off target!!
I tried and maybe did stupid things
I have tried heimdall and kies. Kies does not see the player. Heimdall does, but it did not work or i could not work with it.
Installed and uninstalled Heimdall following their textfile.
I unstalled Kies also. Cleaned up my computer. Updated java. Used ccleaner. etc. Removed unused devices, with 'device remover'
Once or twice i clicked the "re-partition" in odin. With or without PIT-file. Now I read, that this could brick your phone.
I tried all tabs, now i know i should only use the PDA-tab.
I might have done more stupid things.
I found "one-click" in http://forum.xda-developers.com/show....php?t=1153310
It took me a while before seeing that not all things where good for this player type. When rooting htc, a wrong rom won't brick your phone, so i did not take it too seriously.
I tried 1 or 2 roms, before seeing that they where for other player versions.
I tried the GalaxyPlayer-Bootloader.zip from http://forum.xda-developers.com/show....php?t=1386669
Now i see it is specially for player 5.0.
Here i also used the partition file.
At last i did:
Installed samsung usb drivers again: "SAMSUNG_USB_Driver_for_Mobile_Phones_v188.8.131.52.ex e"
When connecting the player to the computer (while already in download mode), windows start 'downloading' the samsung drivers again...
Dont know why and if this can be a problem.
Tried ADB in command, but 'adb devices' does not give a list, but odin seems to work at first.
Odin (3 v3.07) recognizes it and says:
Now in Odin I first uncheck ALL checks like: repartition, auto reboot and refresh time and the others.
I did try the "NAND ERASE" option. Erasing looks to hang, but at last Odin comes back and gives a fail on flashing.
Between every odin try, I remove the battery, unconnect usb and restart the download mode, then connect again, then start Odin again.
Now I tried 3 roms/kernels:
- CWMStockGI1 kernel.tar (http://forum.xda-developers.com/show....php?t=2198444)
- yp-gi1cw.factoryfs.rooted.tar (http://forum.xda-developers.com/show....php?t=1884071)
- yp-gi1cw.kernel.stock.tar (http://forum.xda-developers.com/show....php?t=1884071)
Odin responds when flashing:
<ID:0/010> Odin v.3 engine (ID:10)..
<ID:0/010> File analysis..
<ID:0/010> Get PIT for mapping..
<ID:0/010> Firmware update start..
<ID:0/010> NAND Write Start!!
<ID:0/010> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
I am out of options
