<div dir="ltr">Does anyone here do these CyanogenMod installs for others for cash? The instructions on the Cyanogen wiki and then this inquiry convince me that undertaking this install by my lonesome would be FAR beyond my capabilities. Yet I have a perfectly good Asus Nexus 7 (2013) that Mountain View will no longer update. Or does anyone know of someone who does this mods competently? Thanks in advance!</div><br><div class="gmail_quote"><div dir="ltr">On Tue, Sep 8, 2015 at 5:58 PM gregrwm <<a href="mailto:tclug1@whitleymott.net">tclug1@whitleymott.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><div><div>since firefox frequently grinds GINGERBREAD.UVLDG to a standstill, i want to upgrade the OS on my galaxy sii sgh-t989.<br><br>i've tried both Benjamin-Dobell/Heimdall and jamiejackson/Heimdall, either can examine the phone partitions, and both seem to go thru the motions of flashing the recovery partition according to the linux end, but the phone doesn't show any blue progress bar, instead shows "Firmware upgrade encountered an issue" (clearable with "close-pc-screen"). i think my usb cable is fine because adb push works and the pushed files' md5/sha1 are fine.<br></div></div></div></div></blockquote><div><br>"ok, got it." well i posted the question, and finally found the answer, so i'll post it. bore warning, unless you're interested in upgrading the OS on a t989, or find amusement watching mice in mazes. i chose <a href="https://download.cyanogenmod.org/get/jenkins/122888/cm-11-20150823-NIGHTLY-hercules.zip" target="_blank">CM11</a>(kitkat),
seeing reports that lollipop and other roms are not as good for battery
life. getting there, well, in retrospect, simple enough, but wading through endless outdated or inapplicable or inaccurate even tho very well intended misinformation may not be the quest for the holy grail but was no piece of cake either. the <a href="http://wiki.cyanogenmod.org/w/Install_CM_for_hercules" target="_blank">cm t989 install instructions</a>
are pretty poor, clearly generated from a template and often misleading
for the t989. even so they were indeed helpful and should be read
carefully. maybe my summary here might help someone, like even myself
if there's ever another goaround on this phone.<br><br>first i tried fastboot. from my attempts, and from something i read, i ended up concluding it didn't support the t989. in retrospect i wonder if i was misled by the same circumstances confusing my attempts using heimdall. i was hoping not to have to compile heimdall from source, warnings abound about against using mainstream heimdall versions on a t989. i ended up compiling several versions of heimdall, both under vivid and under precise, looking for one that would work. following some cm wiki page for building heimdall was a mistake. the
source tree Linux/README is good if ignoring all but Appendix B. and <a href="http://wiki.cyanogenmod.org/w/UDEV" target="_blank">this page</a> explains how to run heimdall&adb as a normal user.<br><br>from my experience with
my d710, not seeing a blue transfer bar on the phone led me to presume that meant heimdall
flash wasn't working properly, plus i was getting "Firmware upgrade encountered an issue" on the phone, whereupon trying to reboot the phone
would just return to that message. eventually i found that "heimdall close-pc-screen" clears that bootlockout, tho only when omitting "--no-reboot".<br><br><a href="https://github.com/jamiejackson/Heimdall.git" target="_blank">jamiejackson/Heimdall</a> did work on vivid, i was able to realize, once i let go of looking for a blue transfer
bar on the phone, and stopped trying to flash CWM. trying to flash CWM always
led to the "Firmware upgrade encountered an issue" bootlockout. perhaps a different version of CWM might have worked. TWRP-2.8.7.0 at least
had the grace to boot itself up but couldn't find /sdcard. <a href="http://techerrata.com/file/twrp2/hercules/openrecovery-twrp-2.8.5.0-sgh-t989.img" target="_blank">TWRP-2.8.5.0</a> worked.<br><br>>apt-get install android-tools-adb<br>

incompatible, which tempted me to think perhaps one of the roms touted
on galaxys2root might just include a compatible radio and be an easier
way to go, but i oogled around, found SGH-T989_UVMC6_radio.zip and used
it, even though i had to disable twrp's signature verification in order
to use it. at least the md5 passed. twrp verifies using an .md5 file
if present. md5's are usually provided alongside .zip's but usually not
in the form of an .md5 file, tho the .md5 files are easy to make and provide a
tad of comfort when flashing, especially when flashing a radio without
sig verification. i turned signature verification back on for cm11&<a href="http://itvends.com/gapps/gapps-kk-20140606-signed.zip" target="_blank">gapps</a>.
the sig verification checkbox in twrp's install dialog lead me to
presume i could choose per-zip, but no, the choice is per install batch,
so i installed the radio separately with it off, then cm11&gapps
with it on. no idea if <a href="http://forum.xda-developers.com/showpost.php?p=44646889&postcount=381" target="_blank">this repartitioning warning</a> is applicable to cm11, but anyway i did flash it 3 times.<br><br></div><div>and indeed so far it does seem worth the effort, cm11 isn't grinding to a standstill running firefox..<br></div></div></div></div></div>
