[Q] Howto go from cm-10.1.3 to cm-11 nightly on i9100 intl? - Galaxy S II Q&A, Help & Troubleshooting

I am currently on cm-10.1.3 galaxy s2 i9100 intl (International, NOT G). It has CM-based Recovery v6.0.3.6. How do I upgrade to new rom cm-11 nightly?
1. Can the above CM-based Recovery v6.0.3.6 be usd for the flashing? Any link to a detailed post would be appreciated? I have seen references to problems if the above used, or first one has to goto cm-10.2 etc. It looks like cm-10.2 has been pulled back, I do not see that among cm downloads area.
2. Using the built in 'CM Check for updates' I downloaded the latest cm-11 nightly, it went without any error. But I do not see that .zip file anywhere. Where is that supposed to be?
Any help is appreciated.

The cm11 zip file will most likely be in your internal sd card. You should be able to flash it from there from recovery, but first I would update the recovery to something more recent
Just download the latest philz recovery from HERE You want the "latest philz" from the third post. Flash this recovery, reboot into recovery(not system), do a full wipe after any backups you want to do, then flash the cm11 zip and compatible gapps(optional)
There are other recoveries you can use, just use the latest one if possible, philz is what I use

Thank you very much for your very helpful reply. I have more to clarify now.
A. Well, I found out why I dont see the cm-11 zip file. (I did search in the *nix console with
'find / -name cm-*.zip'. Couple of the other older zips do show up.). To see the problem I had to watch during the full download; towards the end it has a very brief popup like 'MD5 check failed'. I have no idea why the latest cm-11-20150426-nightly md5 is failing at my end!! The previous 20150412 could not be downloaded either (though I was not there to catch the md5 error, but since there was no file, I assume it failed similarly.) So I tried the 20150406, and that did ask me if I wanted to flash, I cancelled that, and the zip is in the /storage/sdcard0/cmupdater/ . Good.
B. I had never used any philz recovery tool before. So to flash this new recovery, I use the current CM-based Recovery v6.0.3.6, just like I load the gapps zip?
B1. When you say philz, from third post, this one? 8th September 2012, 11:40 PM |#3 ?
It says it 'can be flashed in stock recovery 3e: No Yellow Triangle'. Mine is no longer the stock recovery, since I had updated to the v6.0.3.6. My phone has a Yellow Triangle on boot! Does this mean I cannot use this one? Kindly explain.
So philz recovery is different flavour from the CM-10.1.3 based I have? I had used the flashing only once before to come from the stock to the 10.1.3. Are these two recoveries fully compatible?
C. I had already downloaded the gapps zip for cm-11. The date of that is rather old; I assume there is only one gapps zip version for the cm-11?
D. Since there have been so many cm-11 NIGHTLYs out there, no stable, or monthly, how does one select one of the more stable among them. I really do not need the latest, the primary reason is the main version Andorid upgrade, and I want the ones after the battery drain problem, and the music stop problems were fixed. Is there any place where they give a relative 'goodness' grading to these NIGHTLYs?
Thank you for your continuing help.

This is a continuation of my last reply to you. Double checking: The latest zip file I see at the goo.im downloads site phiilz_touch->CWM_Advanced_Editiion->i9100 is
philz_touch_6.48.4-i9100.zip Sun, 06 Jul 2014 22:47:33 GMT
Should I flash this from my CM-based Recovey v6.0.36 ?. After this flash, i suppose I can do a regular phone booting also, before flashing the cm-11? Thank you.

The latest philz is correct - 6.48.4. Yes you can flash it from your recovery, it is just an updated version of the v6.0.3.6, something like 6.0.4.something with touch ui. It will work flashing later android versions where the earlier one may not. Just flash it and reboot straight back into recovery when you are ready to do your backups, wipes and installs.
The nightly cm11's are all very stable at this stage; I would download the latest, but the more important bug fixes were implemented from about mid january(eg. fpbug fix). Anything after that would be ok. The gapps, I would download the latest just before I flashed the rom, you are better off with the latest play services etc. As long as they are compatible to 4.4.4, you can choose whatever gapps you want. I like minimal gapps by @jajb for example, but it's up to you. HERE are most of the gapps available at the moment.
If you can I would download the rom by pc. You are recommended to check the md5 sum whenever you download roms/gapps to make sure the download was successful

noppy22, Thank you. That clears up many things. The link to the gapps is a big help. I had previously read somewhere that my phone needed a small foot print gapps, because the system (?) partition was ony about 500mb. That was what I had downloaded, but I can check the newer ones.
How do I check the md5 checksum after the download? I have access to the terminal, and I can use minimal *nix commands, once i know the utility name At philz, there were .zip and .zip.md5 of the same version date. Can I flash either one? I know, as I mentioned in two msgs ago, when I use the system download of nightly, it automatically checks the md5, and saves only if it is correct. But I simply downloaded the gapps, and the .zip of he philz, so I do not know how to check the md5. Info-zip versions of zip has their own integrity check with unzip -t, but the unzip in busybox of Android appears minimal without those features. Thank you agian, I am almost ready to upgrade, as soon as I hear back from you

Yes you are generally better off with a smaller gapps package due to the smaller /system in the s2, more so in the newer lollipop roms.
You can check the md5 in a variety of ways, google will tell you ways to if you want to search, and there are apps in the market that check for you. I personally use hashtab, which you download to your pc. It gives you a tab in "properties" that allows you to compare the md5 value against the download site

---

Thank you. I got my s2 running on 4.4.4, thanks to your help. Everything went fine; I will reload another newer 'small' gapps pkg soon.
As for the md5 check, I was wondering if there is a way to do that from the phone (after a download) or using philz recovery, after download of a .zip.

Just go to play store and search for "md5 checker". There are several there. Sorry I haven't used any, so can't recommend but they should be able to give you a reference point

I have run into a problem, and I am stuck. While playing with the setting of profiles, I lost wifi, and the cell connection permanently. It is possible there is bug in the new profile version. Anyway, I flashed again the same nightly (after wipe for loading a new rom), and then this time without the gapps re-flashing, booted the system up. Both the wifi and the cell connected this time. Of course there was no google apps. So, I reflashed the philz advanced (the cm flash always gets rid of the philz advanced), then added the same apps pkg as before. But then when I booted the system up, both the wifi and the cell were not connecting!!
Any suggestions? Thank you.
PS. A related question. Does philz provide a way to save all the installed up and their setting to the external sdcard, and then reboot it? I am particularly interested in the settings save and restore.

I don't know about the connection problems, you could post the problem in the cm11 thread as it is more specific to that rom. I have heard problems in cm12 with using gapps not released by cm, so you could try cm gapps HERE
Other than using the backup feature of philz, there isn't really any option to save settings. You could check out titanium backup from the market. It has the most comprehensive features for backing up apps and settings, although I have had problems with re-installing stuff using it, but plenty of people swear by it....
