I have successfully updated my u8800 pro to ics........ But the problem after update is battery is dying very fast and phone is a lagging for normal use
What should I do to resolve this

If I want to convert back to 2.3.5... That was my previous android version
Where can I get this upgrade file
 
Hi, U8800 2.3.5 is available here:HUAWEI U8800 - Huawei Device Co., Ltd..

You can Download and Save to Desktop.
The following I found at XDA Developers and thanks to Author. This guy had installed ICS (Aurora):

Hi to all!

I just want to give this tip of advice to those complaining of slow wireless, internet speed and high battery consumption.

Just use setCPU on "performance" at 1GHz (some profiles recommended, such as screen off, charging, less than 50% battery, at least...)

I was having very slow wireless and since I used this method, I have over 15 Mbps on wi-fi (800 Mhz) on speedtest.

Also battery usage decrease due to the fact that the phone doesn't need to scan the cpu everytime to decide witch speed to choose.
Ramping up and down the cpu will eat your battery more than just leaving it at high speed all the time.
With smartass or min/max at 245/1024, the phone uses 10% or so in standby.
With performance at 245 Mhz (screen off profile) it used only 4%.
Normal usage at 1024 also uses less battery overall.
======

OK, let me add some more info for those people that ask for it:

- Get SetCPU 3.x.x (whatever latest version is), create some profiles and set on boot.

- The first "Main" tab, set min and max as 245 / 1024, performance and also set on boot.

- On the "Profiles" tab, enable profiles and add these:

Screen Off
CPU min 245 / max 245
Governor: powersave
Priority: 60
Exclusive

Charging Any
CPU min 1024 / max 1024
Governor: performance
Priority: 50
Exclusive

Battery <= 30%
CPU min 368 / max 368
Governor: performance
Priority: 40
Exclusive

Battery <= 50%
CPU min 800 / max 800
Governor: performance
Priority: 30
Exclusive

By default (without this profiles) CPU is being scanned for activity every few seconds (or milisecs) and it will decide based on the activity to either up or down the CPU clock.
We all know that Android system keep tasks on memory and therefore open background processes...

If we use governor min/max, it will keeep "searching for activity" using extra CPU cycles, and thus using more battery.
By using "performance" there is no need to scan for CPU activity and it will be running at max speed acording to the profiles we created.

- Higher clock uses more battery however, because it's faster, it will take less time to finish any task and to return to idle.
- The more time the CPU spends on idle the better for the battery, so by using performance you will finish tasks faster and spend more time on idle.
- CPU will be more responsive because clock doesn't need to be adjusted on the fly, thus eliminating any extra CPU cycles and also saving some battery.

This behaviour is good for quick and short usage of aplications, but maybe not as good for games as it will run at a higher clock all the way until you stop playing the game.
For small tasks, such as google maps, gps, message, calls, internet, etc, it's better to use the higher clock when the screen is off, instead of going up and down adjusting.

By using the profiles above, it will be set at minimum speed while the screen is off and not go up even if there are background processes.
If we use min/max, and android decides to do something on the background the cpu will go up and down (using battery) even if the screen is off.

My tests:

With smartass or min/max my battery goes around 10% after 8 hours in standby.
With my settings above, battery wend down for 4% after 8 hours in standby, but actually when I first checked, it was still 99% after 8 hours.

With smartass or min/max, download speeds on wi-fi and data are slow.
With my settings above, it starts slow but speeds will quickly go up.

With smartass or min/max, my GPS will take a while to get a fix on google maps.
With my settings above, my GPS will take less time to get a fix on google maps.

I thought of this, because battery was lasting longer in older releases of aurora when CPU was fixed at 1Ghz.
With more recent realeases this behavious was changed to be min/max, therefore I started having slower speeds on wi-fi and performance issues.
At first I used SetCPU to fix it at 1Ghz as before, and it improved both battery and performance.

By exploring the profiles section on SetCPU, I just tweaked a little bit more the battery usage and performance.

I recommend anyone to try this, however all users and phones are different and therefore take this tips with a pinch of salt.

Hope this helps. Cheers Neil.
 
Does this boost up the phone cause the phone is starting to get more slow ... i use phone mostly for browsing and gaming purpose and i have wifi at home ... and i always keep the wifi on .....
The main.problem is not the battery drain(of course it is one of the problem) ... the main problem is lagging of phone.... when i use any app and using it when i go back it takes times for home page or the app dock to load and i donot use many widgets on screen too but it takes lot of time to load hone page... and even playing simple games like stick cricket super sixes it lags and the game play.is very slow ... i upgraded phone because i want some speed for my device.... but instead its lagging

Can the above mentioned solution will rectify the problem

Or is it better for me to go back to 2.3.5
 
And the important thing is i didnt root my phone.... Does above method applicable even when phone is not rooted or rooting of phone is compulsory

with out rooting how can we solve this lagging problem of phone..... I am deseprate since i use phone for gaming and even the simplest gaame i cant play
 
I really don't know what your problem is. Like a computer, I would imagine that the speed of operation has to do with how much work the comp is doing. ie. How many background apps are working unnecessarily while you are gaming?
Googling, shows that quite a number of users have experienced similar problems associated with ICS upgrade.
This may be your only source of assistance.
Clearing the cache might help as stored downloaded files slow down a comp. Cheers Neil.
 
I am sorry that i couldnt explain my problem perfectly

But the problem is that whem.i use any app and after.using when return back to home page it takes time to load the home page where as in previous version it used to load fast (and i always clean cache.and terminate the background process)

Any.ways ill try to root phone and apply the above method you suggested.and see if there is any improvement
 
Didnt tried updating again ... but i wii do it again
Does updating cause any problem??????? And yeah iwill disable antivirus this time
 
That is the same problem that i had when i updated my u8800 pro to official ICS. It works normal for some day but then phone starts lagging. Even if i open the dialer then press home button to go back. It refreshes & load the homepage every time. The amount of free memory always stay between 20-30 mb out of 512 mb. Normal games like Temple Run & all other basic games were lagging too.
Then i install GB again & phone is working perfect now. No lag whatsoever & now almost every game runs smoothly.

My advice is if you are rooting you device then install Jellybean 4.1. It is way too better than 4.0 in every aspect.
 
As I understand it, U8800Pro will update to ICS if you follow the procedures correctly. These are in a PDF form in the Download and should be extracted and read thoroughly before doing anything else!
If you want to use any other ROM than the approved ICS, you will need to Root the phone first.
Whatever you choose to do, make sure you search/Google and gather as much info as possible before attempting to Root your phone.
Failing to follow details correctly, can "Brick" the phone - your choice.

Rooting the phone correctly will enable you to Delete unnecessary OE Apps which may slow the phone down after Root. Neil.
