    I need daishi4u's modded boot image so I can have init.d support, but I already have the openrecovery-twrp-2.8.3.0 recovery image installed.  Is it either necessary or preferable that I switch my recovery image to one of daishi4u's before I flash the boot image?

    Am I correct in presuming that my Fuel cannot mount a second partition on the SD card without init.d support?

    Not necessary, but yes preferable (in my humble opinion). With daishi4u version of twrp, you have the added option to install raw images. Very handy. But yes, I believe initd is necessary to mount sdext2 partition. And daishi4u kernel (boot_bumped.img) also enables adb access by default (life saver),and ability to power up into recovery by key press (also a life saver). You can also use terminal emulator to install boot_bumped.img. I'm working on flashable zips, but so far I'm getting errors while flashing. Hopefully soon.

    Thank you, ibub.

    A bit OT but as long as you're here ,) , I've seen references in some fairly dated tutorials on partitioning the external SD card with the intent of moving some internal storage elements onto it that state the second partition must not be any larger than 2GB (but with no explanation as to why).  Since that's exactly what I'm on about, I was wondering if that 2GB is a note that still pertains, and if it does, what is the rationale.

    Anyone care to venture?

    I do recall, in the p500 forum at xda, someone posted that 5 times (1GB) the data partition (200MB) was a maximum for that device. I'm sure that there must be a physical maximum storage that can be addressed. But I really don't know how much.

    This poses something of a dilemma.  Moving apps and such to the external SD was a secondary motivation for getting all jigger-pokery with the external SD card.  The real reason was so I could link the folder that Nandroid backup images are written to to external storage.  Obviously, as you add apps to the Android, there is progressively less internal space for the writing of a Nandroid image.  In my case, pretty early on in the configuration process, there came a crossover point where the installed apps were taking up too much space to allow a Nandroid backup in what remained.  I made a Nandroid backup immediately after unlocking and installing only the minimum apps necessary to execute the backup and it's almost 700mb.  If the internal SD is only 1800MB, that means the crossover point is in just a couple of hundred more MB, which is barely getting started.

    So a 2GB Ext partition on the external SD drive might give some temporary relief, but as the internal storage gets full (which I'm sure it will, 'cuz I have no self-control), I'll be right back in the same boat.


    But at least there is this good news.  My phone died.  Or at least the WiFi pooped the bed.  So I bought another.  Which solves my dilemma of whether to install daishi4u's boot image.  Every dark cloud, as they say, ....

    Just FYI. nandroid backups can be saved to external sd using twrp 2.8.3.0(daishi4u). Yeah, they are huge.

    I didn't know.  Thank you so much for that.  And thanks to daishi4u, too.

    Oh, and another question, if you please, ibub.

    Is there any conflict installing the TRWP manager app along with daishi4u's TWRP recovery image?

    Honestly don't know. Never used it. Was afraid that it might install non-bumped image. But since the official twrp seems to work, it MUST be a bumped image...

    I installed the bumped image, and daishiu4's recovery image.  And I was able to write a Nandroid backup to the external SD card.  The backup was about 1.4gb, even though that was a fairly new installation, little more than what I needed to do all the modding to get to this point; rooted, write-enabled external SD card, w/modded boot kernel and recovery image, etc.  And already it was too big to fit in internal storage.  Ridiculous.

    So thanks again for the head-up.  Now I can afford to blow up my phone (again) with clumsy tinkering, but suffer no long-term damage. ;)

    And you were right again, ibub.  The Nandroid backup was about 1.5gb, which included the minimum of additional installed apps necessary to execute the backup, plus daishi4u's recovery image and boot kernel.  Winrared with max compression, it compressed to 800mb.

    Well, I have reached $20 cell phone nirvana.  I got my 2nd (and 3rd) partitions mounted, moved the bulk of the data from my installed apps to the external SD card, and even got a functioning swap slice in a third partition on it.

    The third partition was a swap slice, which my benchmarking showed to be virtually worthless.  I suspect that comes down to compromises made necessary by building a computer the size of a pack of smokes, and taking advantage of the fact that the device has all solid-state storage.  Details You are not allowed to view links.

    So now I've got (seemingly) multiple times more storage space than previously possible, plus I can do Nandroid backups, even with the phone in a fully-configured state.

    So I are a happy camper. 


    And it goes without saying, props to daishi4u for making all this possible.  Molto grazzi!
