I am searching for two days now without success, so could some kind soul help me with idiot-proof (ok, nothing is idiot-proof...) instructions?
The links in this thread (and other threads) needed to upgrade Huawei U8800 Pro are mostly dead.
I would like to upgrade my 2.2.2 to 2.3.5 and furthermore to 4.x and some good, stable, fast custom ROM based on 4.x.
So atm i am stuck at first point: upgrade from 2.2.2 to 2.3.5. Can anyone help me with working links?
Research so far:
- i read that it is good to backup your IMEI (http://forum.xda-developers.com/show....php?t=1591997
), but how can i do that on 2.2.2 that isnt rooted?
- i downloaded files from Huawei site, for 2.3 update this one: HUAWEI Ideos firmware(U8800Pro,Android 2.3,V100R001C00B521,Oversea Normal) (V100R001C00B521)
, extracted UPDATE.APP to dload folder on sdcard that is in the phone and powered on with volume up+down. At that point it started updating but said "Update failed" after unpacking. In the dload file there is a file now in which it says: "dload_sd_ram_data_proc->(retry >= DLOAD_RETRY) failed! "
- i downloaded from Huawei site update for 4.0 (http://www.huaweidevice.com/worldwid...oftid=NDY1NTY=
) but i cant do much with that one before i get it to 2.3
As mentioned above, my goal is to upgrade to some stable, fast 4.x custom rom, so if i somehow manage to get to that point, i would love to know which custom rom is... well, the best?
So i am kind of stuck at the moment. Heeeeelp!?
