Firmware downgrade?

[Guest Andy Veliz]

Hello, I just updated my Non Pulse u8220-6 to the last firmware from huawei : http://www.huaweidevice.com/cn/downloadCen...C17B278SP01.zip

but i guess it changed something because now the custom recovery doesn't work... it doesn't restore backups or create backups nothing, maybe it's something related to the partitions?

can anyone help me?

btw when i load the custom recovery it throws a warning:

CAN'T MOUNT CACHE: recovery/log

Try to install the recovery image again. When applying the December update on the Pulse we loose root and the custom recovery image. Maybe this is the case with the non pulse too.

[Guest ogiogi]

So did u try to reinstall the custom recovery image?

yes i did, but since i dont have a pulse with "december update" Vol- + home doesn't work

and because I dont have root access i can't "reboot recovery"

and with this firmware I don't have android market, so i cant use quickboot

:S

i'm kinda stuck with this one...

[Guest Andy Veliz]

i was looking a little more into this issue and it the thing is, it cant mount the partitions

i'm doing this in the "loaded from the pc" custom recovery, the only one i can access.

cat /etc/fstab

/dev/block/mtdblock1	/system yaffs2  rw

/dev/block/mtdblock3	/cache  yaffs2  rw

/dev/block/mtdblock2	/data   yaffs2  rw

/dev/block/mmcblk0p1	/sdcard vfat	rw

/dev/block/mmcblk0p2	/system/sd auto rw

but when I ls /dev/block

ls -la

You can access the bootloader through PWR + red key + vol down.

Then reflash the recovery image.

Once this is done, you should be able to boot the recovery image :)

Maybe a different key combination :)

doesn't work in non pulse model...

i had to run adb reboot recovery from the "non-working" "loaded from the pc" version of the recovery... ehehe

then the recovery image worked...

now trying to flash the 1.7 vanilla ROM...

[Guest Andy Veliz]

Nice! everything works, had to replace my boot.img with the one in the firmware update, but now i have the 1.7 vanilla ROM...

i'll try ur 2.1 ROM Bear...

HI.

'm Chilean too, and my u8220-6 was left stuck on the screen huawei

'm , urgent need to reactivate my phone, and the only thing achieved was update it to a Japanese version.

please, if you have the image of restoration of the u8220-6 can pass me?

and help restore.

Hola.tambien soy chileno me fije en tu bandera, tengo u8220-6 y un dia x se quedo pegado en la pantalla de huawei,

lo actualise a una version SP03 y quedo en japones, lo mas que pude hacer fue eso y dejarlo en ingles.

no me incomoda el ingles para leerlo pero, no tengo ninguna aplicacion, como android market, gmail. etc..

Si tu tienes los archivos originales de este telefono, me los puedes pasar y de paso ayudarme a restaurar el error que cometi,

al intentar resolverlo yo.

Te lo agradeceria a montones.

Saludos

heyy, mira, una vez que avanzas con el firmware, ya no puedes volver a la versión original, así que tienes que seguir avanzando, yo lo que hice, hacer un nandroid de la version china para salvar el boot.img, instalar el rom 1.7 vanilla style, como si tuvieras el "december update", y volver a flashear el boot.img de la versión china... ahí queda en inglés, pero con market y con todo... funciona bien con claro... voy a probar el ROM 2.1, y si me va bien, publico una mini guía para los usuarios de u8220-6 :)

un abrazo
