[Galaxy S II General] tantoine:
CWM quiery

Hi all,

Brilliant forum, lots of knowledge here to sift through.

As you can tell below I wrote this to go on a devs specific thread due to the nature of my quiery, but was unable to post, I've got to make 10 post on Q&A threads before I can submit there. I appologise if this thread is the wrong place to post, I'll also try posting on the clockwork mod thread (sorry if posting twice also affends). But maybe someone here could help, please;

Hi Phil,

I think the work you do is amazing, cwm is a brilliant bit of software, thankyou for letting me use it.

But I have a couple of questions if you have the time..?

Firstly I am a bit of a noob and not really a tweaker of phone softwares like yourself and everyone on this forum. I started, only to solve a problem with my phone but every solution brought another problem.

I've been trauling the internet (forums like and including xda) for at least three hours a day, nearly everyday for the last 2 months.

At first it was interesting learning what all the letters mean in firmware packages etc but continual searching is now just confusing me, hence the post.

I did learn from reading all the posts that you like to have all the details, so I suppose I should start at the beginning;

My mistake was buying a second hand s2 which was branded to "3" network and thinking it would be easy to unlock.

Originally my phones firmware was PDA; i9100XWLPI PHONE; XWLP4 CSC; XWLP4H3G a bit of research on the intranet showed your file; PhilZ-cwm6-XWLPI-DBT-2.7-signed would root my firmware and enable me to run an unlocker app, which worked perfectly.

All unlocked and working on the giffgaff (O2) network at this point for a happy couple of weeks until the twLauncher decided not to work any more.

More research on the web followed, aledgedly I could download another launcher from the play site like GO, but after many many atempts trying to install it (including through computer) I simply couldn't get to the relevent parts of the phone.

Yet more research and a expensive paper wieght looming I came across this "LK95-SimplisticPS-XXLSJ" which can be found here; technoxide /2012/11/galaxy-s2-jelly-bean-4.1.2-I9100XXLSJ-update and after flashing the .zip file through CWM recovery, which also worked perfectly, I started to enjoy the new jelly bean.

I thought it smooth at first, all but a few hangs here and there which to be fair was commented on their website, so was to be expected. however; smooth as it maybe the call reception was very poor most of the time and it has a nasty habbit of just dropping the connection to be replaced with "emergency calls only", often..!

Back to the forums for more research, following which I downloaded Network Signal Info (NSI) app and Speedtest.net app and checked the signal status on O2.status which reported No 3G but good 2G signals with no maintainence being carried out.

After multiple tests in different locations speedtest.net returned a PING of; always ranging between 1000 to 1800, Download range between 16kbps to 39kbps and an upload speed range between 25kbps to 29kbps.

Although I don't really understand the results from NSI (the explanation on wiki and forums didn't really do it for me) it usually reports an DBM range between -93 to -103 but most of the time resting on -99 (which I read is supposed to be impossible for reason I know not).

I've read the DBM is better the closer it is to the + numbers, less noise or somesuch. ASU ranges from 1 to 7 normally but once strayed to 12, it also reports it connected to the O2 UK network (when the emergency calls bug lets-up for 5 minutes.!), net type is GPRS 55kbps.

Most of the time it reports DBM -99 ASU 7, by far the most common. Signal percentage is 29%, percent 0; 33%, DBM; -99, DBM 0; -97. In the ear-piece reception it's very poor also and I know the reception's not that bad because a mate stood next to me at nearly all instances in testing who had very good reception with a vintage nokia on the same network.

now,I know 2G isn't lightning fast for internet or too super for calls and mms but my previous phones could happly send a text or mms in seconds and calls were clear, but my current S2 however delivers sms as when it feels like it (delays have know to last several hours, recieving and sending), MMS can take between 30 minutes to 8 hours to send a 800x400 picture...!

I know the networks better than this so it's got to be the phone. no...?

Yet more trauling forums I find out you can change the modem by flashing a .zip in CWM which doesn't effect the jelly bean firmware unless you download the .zip including the Ril files which aren't compatible with JB yet.

After downloading 6 or 7 zips (without Rils) which other people have been using with good results on my network and in my area; I was ready for testing, but when trying to instal any of them through CWM I get STATUS 7 instal aborted.

Back on the forums; It appears this error is something to do with the binaries in CWM not recognizing the modem zip. I don't claim to understand this either (simpleton, sorry. I try, but...) but I think I have to update something somewhere.

So, provided you're still awake after reading this; to my questions.

Note;I have made the rellevent back-ups with Nandroid, titanium, EFS folder and Kies so all prepped.

I was thinking about flashing the latest "Philz-cwm6 v4.00-b22 cwm 6.0.2.7" through my older cwm on my phone, would this just update CWM and leave everything else as is or would it wipe everything....?

And would this now enable me to flash modems via .zip in cwm...?

But, after reading back through this to check, maybe I should instal your

<<21.01.2013 - PhilZ-cwm6 v4.00-b21 with CWM 6.0.2.7 based recovery >> XXLSJ-OXX (Jellybean leak)

or even

<< 23.01.2013 - PhilZ-cwm6 v4.00-b22 with CWM 6.0.2.7 based recovery >> XXLS8-FOP (Jellybean)

maybe they are more up to date, less bugs etc than the firmware I have installed.

I would really appreciate any thoughts you have.

Any information I've left out that you need I'd be happy to post.

Thanks for your time.

ps. thanks to anyone that can help.

EDIT; Thanks to It_ler and ApriliaM3 this

has been resolved

now by flashing "PhilZ-cwm6 v4.00-b22 with CWM 6.0.2.7 based recovery >> XXLS8-FOP" which removes the error 7 problems and allows you to flash any modem.

Side note; After flashing XXLS8 modem+ril combo this has resolved the "No service; emergency calls only bug" with good clear reception in it's place. Thanks to ApriliaM3 for making and keeping these files for everyone to tinker with, downloaded from his dev site.
