[Huawei Ideos X5 U8800] ggunzio:
hi guys. I have a huge weird problem after the downgrade.

on MIUI (last release) i can mount the external sd and the internal, but cannot copy to them, because they are write protected :O , when i saw this was like WTF?!?!

can someone explain me what can I do to overcome this problem!? I've tried system restore aka wipe data/cache, already tried to flash again and the problem persists.

What can I do? Even on stock 2.2.2 after the downgrade, i can mount the external SD but after unmount i need to mount it on the memory tab in definitions.

Someone with know how, pls help me!

Thks in advance.

If necessary i can try a logcat of something if it helps (but i need some advice on this too)
[Huawei Ideos X5 U8800] nrdl:
enter project menu and test other USB modes... In my case works on google mode.
[Huawei Ideos X5 U8800] ggunzio:
Sorry for my noobish, but where can i find that menu?
[Huawei Ideos X5 U8800] ivosantospt:
menu

Dial * # * # 2846579 # * # *

Go to projectmenu, background settings, log settings, log switch and set Log on

And

Set USB menu, you have that you want.

How did you downgrade I get a boot loop after trying to install miui after downgrading to 2.2
[Huawei Ideos X5 U8800] HFZenon:
Remember to do a factory reset / clear cache inbetween flashes. I always do and have never had any problem with bootlooping. Think it has something to do with filesystem changes from 2.2 to 2.3 (EXT3/EXT4 etc.). I also clear Dalvik-cache.
[Huawei Ideos X5 U8800] ggunzio:
hi again. I'm on MIUI and I can't access that menu.

Conclusion... If I want to put my cell phone on it normal state, I need to flash it again with 2.3.5 right!?

ohh god! Never more Huawei... NEVER!

Could someone tell me if I have another way to put things right again!?
[Huawei Ideos X5 U8800] ggunzio:
ohh god!

320 views and no one can help me! :(
[Huawei Ideos X5 U8800] ksatta:
Hmm. You're using an after-market ROM and blaming Huawei, interesting :)

Anyway, yeah it looks like dial foo doesn't work in cm7 either. It might work in 2.2 stock, but you'd have to flash 2.2 or 2.3 from Huawei in any case.
[Huawei Ideos X5 U8800] ggunzio:
lol ksatta. you are a little bit right. but it's the same situation in official rom or miui or cm7 or anything else. Today i will try to flash the stock 2.3.5 rom again and see what is gonna to happen.
[Huawei Ideos X5 U8800] ksatta:
Yeah the official beta seems to mess up SDcards on many occasions, lots of people having problems. Ofcourse it's Beta, but still I guess it's ok to blame Huawei a bit :)

I wonder if the USB mode thing fixes it, we're trying to solve similar issues in the beta 1 V2 thread.
[Huawei Ideos X5 U8800] jukkus:
I Went back to miui after official beta2. Everything else is fine, but now i cant access to internal sd at all... External works fine. Tried change sd usage setting from x5 settings without success..

And another thing.. Does anyone have that huaweis backup program apk? I'd like to install that so i can restore my backup.
[Huawei Ideos X5 U8800] ksatta:
Hmm, do the stock roms even support internal SD when external is inserted? not sure. Anyway I remember that in CM7 there was in the changelog at one point that internal SD is mounted as /foo.
[Huawei Ideos X5 U8800] NihilistWarGod:
I´m stuck with 2.3.5 beta 1 and it supports both. But dammit I want to flash MIUI again.

The new CWM doesn´t work for me. And I´m afraid to brick this crap trying the downgrade 2.2
[Huawei Ideos X5 U8800] boss_y:
Did you tried genlokar's CWM 5.0.2.7 (originally made for pro version)?

This one also works with normal U8800.
[Huawei Ideos X5 U8800] NihilistWarGod:
I´ve tried that, since it is supposed to be the only CWM that works with official 2.3.5

But after the 3 wipes when I try to flash any custom rom I get:

assert failed: getprop("ro.product.device") == "u8800" || getprop("ro.build.product") == "u8800" || getprop("ro.product.board") == "u8800"

E:Error in /etc etc path.../

status 7 installation aborted
[Huawei Ideos X5 U8800] jukkus:
You're right. They don't mount as sdcard at the same time. In my case I can't mount internal SD even without external. It seems to be mounted as /emmc all the time. Not as sdcard.

Continuing this in development/MIUI multilingual thread. Seems like I'm not alone. Some problems with su...
[Huawei Ideos X5 U8800] ksatta:
You can get it to flash if you comment out the assert(..) line from the .zip/META-INF/com/google/.../updater-script. I got CM7 to flash OK without downgrading to 2.2 first, BUT I didn't get CM7 to boot, tried lots of things. The assert line just aborts the script if the phone is not a U8800, the recovery might report it as u8800pro or something.

I think the 2.3 update also updates some of the non-standard partitions or something, but it might take a while before I look into it again, I spent way too much time on it yesterday :)
[Huawei Ideos X5 U8800] NihilistWarGod:
Thanks a lot for the effort on that! I regret every day for trying huawei's gingerbread...
[Huawei Ideos X5 U8800] ksatta:
Well, when the sources are released and all the custom roms are updated with those, things will be better :)
[LG Optimus 2x] tonyp:
tl;dr:

A SU660 BB (824, 1120, 0420) will fix the weird static noise and bad call quality issue on "made in Korea" devices!

You'll find more information on this issue in this post and more information (including known issues and fixes) on BB 824/1120/0420 in the second one.

Original Post:

-------------------

I just want to share this with all of you who might have missed it within the CM7 Nightlies and Baseband discussion threads - and want to gather all information about this into one thread.

This was found out originally by vadonka here.

I found many others who confirmed that people on the other end of your call complain about static noise (like the noise when you're holding 2 phones together or standing next to a speaker).

We were not able to track down why some p990 users suffered from it and others don't. Some could fix it with the 502BB - some with 725BB and the Gingerbread leaked ROM - but not with CM7.

It appears that there are different (hardware?) versions out there.

If your device is "Made in Korea" (you'll find that info on a sticker under your battery) you might suffer from this noise issue - but not all Korea-made devices do.

For "Made in Korea" ones this noise is almost gone with SU660 BB and a matching RIL (824, 1120, 0420)!

These basebands are for the SU660 (the korean version of the P990), but work for us, too.

I'd almost given up on this issue - was using the leaked ROM (which sucks if you wanna use CM7) and intended to sell it soon. I tried nearly every possible combination of BB/RILs with CM7 some time ago - and never got rid of this problem. My poor girlfriend had to answer maaaaaaany test calls hehe.

This weekend I thought to give CM7 one more try, lurked into the CM7 nightly thread and found this Baseband which seems to fix my issue.

It's confirmed to work for the "Made in Korea" 2x's of vadonka, Sckank, TrymHansen, pastime1971 and temasek.

You'll find more infos on known issues in the 2nd thread.

So - why are Basebands which are made for the SU660 working best with our "Made in Korea" P990's? This could explain many of the "hard to track down" issues some people have - because their phones differ even if it's the same model.

You can get 824/1120/0420 BB and RIL here: P990 Complete Baseband Overview Thread

There you'll find BB and RIL install instructions, too.
[LG Optimus 2x] tonyp:
positive comments

pretty similar to 725BB - if you don't have problems with 725 BB stick to it, as it might have less issues!

good call quality on both ends

good battery life (neither better nor worse than e.g. 218 or 725 BB)

good network speed & connectivity

no wifi problems

known issues with SU660 BBs (824, 1120, 0420)

Fix:

There is a fix from pastime1971 if you're using CM7, you need a CM version with the following fix cherry picked though: "Change Iaaf7f1c4: LGEStarRIL: Apply DST regardless of Infineon fix (PATCH #3)"

In temasek's or owains KANGs this fix is already included.

Head to their threads to download a ROM and get instructions how to enable automatic time.

Fixes:

- Installing Toggle 2G/3G will fix this with the "Turn on 3G manually" setting! (confirmed by rugglez, thx!)

- Set 2G manually (duh!)

This can happen with other basebands as well, it seems to be a BB/ROM combination issue

Fixes:

- activate and deactivate airplane mode

- use 3G

Fix:

- please refer to this post to restore your IMEI.

Fixes:

Well your phone isn't compatible to 824BB - you should install 725 or 218 instead.

As it's not compatible you shouldn't suffer from the "Made in Korea"-Noise issue anyway.
[LG Optimus 2x] Mungulz:
So this is the dial-up-esque noise that pre-warns of any impending text messages/phone calls?
[LG Optimus 2x] stpsp:
plz tonydl i wana try 824 BB and RIL , i'm on cm7 7.2 the latest kang , but can you tell how to change it ?? (a mini guide plz) :D
[LG Optimus 2x] tonyp:
No - it's a quite disturbing noise on the other end which won't stop. If you're not suffering (better: the people whom you're calling) I wouldn't advise this baseband.

Sure - just follow Pauls guide to change the baseband here.

For getting the matching RIL I use sibbors "GetRIL" app: https://market.android.com/details?id=com.sibbor.getril
[LG Optimus 2x] grognaz:
i flashed 824 yesterday and i have a couple of problems with it.

every reboot i have to set 2G only again, seems to reset/ignore the GSM only option and the timezone is 1hour behind...

so far i have not noticed any noise like i had with 725 but havent used it a lot so i will continue to listen and ask if its better than before
[LG Optimus 2x] tonyp:
Yep, it's not perfect. As I said before, you need to disable automatic time for the moment - which is probably due to the "fix" I mentioned above.

I can confirm that 2G makes some trouble - maybe Toggle 2G/3G will help you?
[LG Optimus 2x] grognaz:
well it no serious problem once its set manually and since i never use 3g i just have to think about enabling the 2g option when i reboot. maybe i could try if green power can handle the 2g only option... lets see

edit: nope doesnt look like it since green power works with the device settings which are messed up. however, as far as i experienced it might be a problem with cm7, i think i have some strange behavior with every bb except 208 if i remember correctly.
[LG Optimus 2x] GuestK00293:
Beware of imei getting hosed when you install Korean baseband. There is a way to recover and keep it handy. I used putty on windows to fix it when I messed up a while ago.
[LG Optimus 2x] Sheppie:
This also explains why I my phone keeps rebooting and showing BSODS when installing Spica's HP kernel. I always thought that it was strange that there where different versions of the phone.

FYI, I tried different BB and also the 824 with MIUI but the battery drain was awful. LG just released V20M for the Netherlands so i got stuck with the 725 BB.

I don't complain about the quality and I didn't try the 824 with this version. Maybe later when i'm sick of this one :p.
[LG Optimus 2x] afpapa:
I have a "made in korea" device with 725 BB (from v20c I think) and 218 RIL. My rom is CM7 204. I have asked a lot of my friends and family and no complains for the quality.
[LG Optimus 2x] tonyp:
That's interesting.

Then there're even some more differences than "made in korea".

LG has somehow managed to fix the static sound for their v20x builds with 725 BB, but CM7 hasn't.

Does anyone have an idea how to track this down to help the devs to build a workaround? I am pretty happy with 824 BB right now, but I would prefer to have a choice.
[LG Optimus 2x] drpele:
I have a P990 assembled in Korea and it had awful call quality with every BaseBand except 0502 and 0824.
[LG Optimus 2x] grognaz:
i have tried 502 and it was also pretty good but the battery drain was a lot higher:O

so im back to 824. anyone know if there is a fix for the automatic time beeing off by an hour? i remember that this was present in earlier nigjtlies and got fixed somehow, so maybe the same fix can be used on this case.
[LG Optimus 2x] tonyp:
There is a fix from pastime1971 if you're using CM7.

You need a CM version with the following fix cherry picked though:

Another small issue: the call initiation is a bit longer - if I'm too quick with saying "hello" then the other end won't get it (and vice versa).

Can anyone confirm?
[LG Optimus 2x] grognaz:
hmm now that you mention this i remember that i was talking over the headset with a friend and when i unplugged it he couldnt hear me anymore. i had to enable the speaker so he couos hear me again, after switching it off again everything was fine.

its like the mic didnt switch from headset to phone when i unplugged it:/
[LG Optimus 2x] tonyp:
I cannot reproduce that. Which ROM are you using and which BB/RIL?
[LG Optimus 2x] Medizinmann:
Hello!

Mine is also made in Korea.

I tested 0622, 0725 and 0823 - 0824 didn't work.

Voice quality was always acceptable didn't notice any problems there.

But overall signal reception(especially indoors) is by far better using 0823 - but this might be a special because my provider is known for bad reception indoors…
[LG Optimus 2x] Sckank:
Only one issue in Norway with 824bb. We have 2 network here. NetCom and Telenor. When I call someone in NetCom I can't here them. If they call me, no problem. Very wierd. Lucky me only know one with NetCom ;)

Boot to recovery and flash it.
[LG Optimus 2x] stpsp:
it didn't solve my problem, any suggestion ?
[LG Optimus 2x] tonyp:
First - don't panic, you can restore it!

Someone mentioned that it can happen when you check "Erase CP" in nvflash.

It never happend to me, but I found the following solution (which needs an LG ROM - CM7 won't work):

If this doesn't work or you need more info, you could start at this point (one of the links in his post brings up the solution above): http://xdaforums.com/showpost.php?p=19177954&postcount=10951

Or search for "imei" in the cm7-nightly or the baseband thread in the android development section.
[LG Optimus 2x] FPSAUS4EVER:
hi so hows is the battery life with this baseband(824), because i want to install cm7 and i want the baseband with the best best battery.
[LG Optimus 2x] tonyp:
I didn't notice any battery difference to BB 725 which I used before.

temasek said somewhere in the nightlies thread pretty much the same.
[LG Optimus 2x] rototrol:
Just installed this BB (and relative RIL) with CM7 temasek KANG 22 and I must say I'm extremely happy with the call quality I got from it. My p990 is a "made in Korea" one and I really never had the static noise problem on the other end during calls with any baseband; what I really needed to be fixed was the audio distortion on my end of the call. Now I'm finally able to understand what the other person is saying on the phone! :)

I can confirm there are issues during call initiation: when I start a call the first tone I get is slightly distorted, but the line adjusts immediately after. Further investigation is required to understand if I get issues with incoming calls, too.

Connectivity seems flawless (on par with 218 BB) and battery life showed no change up to this moment but maybe I should report on this later.

EDIT: It seems I cannot connect to my service provider help desk anymore. On p990 BBs I've always been able to connect to the special number 155 but now the phone starts the call (the timer begins counting) and there's no audio...
[LG Optimus 2x] tonyp:
Yes please keep on reporting :)

If we got enough people and data I will contact aremcee and ask if some problems might be software related (like automatic time) and we could get a fix in CM7. As for quite some people BB824 is the only "fix" for proper calling.
[LG Optimus 2x] pyssoo:
I have a Made in Korea device and I have no problem with the noise during a call. I never had this problem regarding the baseband. Also basebands 823 and 824 with their coresponding rils don't work on my phone. I had no GSM signal when i used them.

I'm using the phone on Vodafone Romania.
[LG Optimus 2x] MisterGT:
Hmm, looks like my data connection often drops using this baseband. More people having this issue?
[LG Optimus 2x] rugglez:
Does Toggle 2G/3G fix the 2G issue? Can anyone confirm this?

Though no risk or big issue in trying myself, just thought of asking before trying it :)
[LG Optimus 2x] spyrosk:
Stupid question. How do I install the baseband.zip? From recovery mode's (cwm) install zip from sd card?

I have tried Toggle 2G/3G and can confirm that it works on CM7.2 (Temasek's Kang) with Ironkernel. It should also work without problems on other CM7 ROMs.

To install it, just download Toggle 2G-update.zip from here (OP): Toggle 2G/3G and flash it in recovery.
[LG Optimus 2x] rototrol:
Another heavy side effect: I can't call my bank's toll-free number. To be more precise, I can call but I get no sound. This is the same issue I get when I try to contact my provider's hotline. What a shame, this is probably my deal-breaker with this baseband!

[LG Optimus 2x] tonyp:
Worth a try I guess - don't have any experience with your bb.

Where did you get 1035?

And you could try to disable "automatic time" - some people say it helps with loosing signal.
[LG Optimus 2x] amateru:
Honestly, I think the noob side of me got the numbering wrong.. because when I double check with the thread,

It says 0725 from v20m haha.. sorry for the misleading post..

v20l RIL for SU660 BB

As he said, I am using v20l RIL and it's working perfectly (I am on MCR Gr6+HP RC12 with 1120 BB). I tried 1120, 824 and 823 RIL, all of them resulted in unknown baseband.
[LG Optimus 2x] tonyp:
TrymHansen already tested 1120 BB and confirmed that it will behave exactly like 824 (aka gives us a good call quality, too) :)

Will test it by the end of the week and update the thread.

For the RIL: Just use one of the RIL Apps ("LG RIL VERSION" or "GetRIL") and get the matching RIL - that's the easiest way I think.
[LG Optimus 2x] temasek:
Yes

1120 Good voice clarity.
[LG Optimus 2x] tonyp:
Did my testing with the new BB, it works good, too.

Actually I didn't notice any difference between 824 and 1120.

Updated the first post :)
[LG Optimus 2x] Gonox:
Finally so more annoying sound in the incall background!
[LG Optimus 2x] eViLsTieFel:
You probably should've mentioned something about potentionally losing your IMEI when flashing 824 in the opening post.

Even though I have a korean made P990, this has just happened to me (no, I did not check ERASE CAL or similar options in smartflash). Currently, I'm trying to figure out how to make my phone work again. Not too much luck so far.

NVFlashed the original firmware, tried the steps using HyperTerminal. Unfortunatelly, when I select CP USB, the phone doesn't connect to the PC. I just get the periodic USB connect/disconnect sound without any device being installed or showing up in the device manager.

I of course do not blame you for me bricking my own phone, but it's meant as a heads-up for anybody else willing to try this. Does anybody have any suggestions as to how to fix my problem? Would be most appreciated.
[LG Optimus 2x] Kostja_V:
May be its problem of your USB cable or jack? I have lost my IMEI about 6 times, after checked ERASE CAL option and after installing 824 baseband, but always method using HyperTerminal worked for me.
[LG Optimus 2x] eViLsTieFel:
I've managed to solve the issue by flashing the original baseband 218 and then using NVFlash to reset my phone.

The usb cable and jack are fine, never had an issue with them ;-). Thanks for your advice, I'm sure most people can get the original method using HyperTerminal to work.
[LG Optimus 2x] tonyp:
Thanks for sharing. I've added the IMEI loss as a "known issue" in the second post.
[LG Optimus 2x] zanor:
This may be related to the kernel/software. Because when I use FR19 from MoDaCo (Based on stock Froyo) I have no static noise or any complains from the recipient using the recomended 0622 BB for this rom.

But when I change to CM7/CM9 and do use the same BB/RIL combo I get this static sound..

What have he done that CM is missing?

Using a korean BB is a no go for me because I loose sim toolkit.

BTW my P990 is made in Korea
[LG Optimus 2x] tonyp:
Yes I'm aware of that. LG somewhen fixed this issue. I already contacted RC but he never answered me unfortunately :(
