Custom ROM -> ICS

Just wondering, if I were to flash to a custom rom, such as Thor... then a few months later ICS comes out for our tablets, what would the upgrade process entail?
I'm hesitant to try a custom rom, because when ICS finally comes I don't want there to be extra steps in order to get the update.
Anyone know how difficult/easy this is going to be? Will it involve having to flash back to stock first, then OTA to ICS?
TIA!

Not trying to be rude but honestly, if youre afraid of a few extra steps than rooting and android is not for you. I suggest an apple product.
But to answer your question, when official ICS comes out OTA Im sure devs will create custom roms that you can just flash. I mean we already have ICS ports in the works.
Why would you want crappy OTA ICS when you could have a faster, custom rom ICS .

Don't assume. I already have ICS running on my Galaxy S; I'm sure I've flashed and reflashed android devices just as much as anyone else here. It's not about being afraid. It's about convenience for a device I've come to rely on day-to-day.
Thanks for the post, anyways. But I'd still like to hear what the process would be to go from a custom rom to the offical OTA ICS.

From what Ive read (search function), you can update from a custom rom but you will lose root.

If u rely on this day to day, u do NOT want to flash an ICS rom yet. Not even close for day to day use.Stick with what u have and just be patient.

I agree wait for the kinks to be worked out.

If you rely on this device pretty heavily, and you still want to get ICS when it comes out, I would just recommend flashing a custom ROM now that is known to be pretty stable. like you suggested, Thor's ROM seems to be a great one. It definitely improves the speed of the tablet and I have yet to come across any bugs that would inhibit my everyday use. Then, once developers have worked out a ROM for a relatively stable version of ICS, you shouldn't have any trouble switching to that and not worrying about the OTA updates.

Well, if you're familiar with all that, then you already know how to flash an OEM ROM and would know you already knew how to do it.

can be a bit of a pain going back to stock ota updates. Depends on availability of your devices localized stock rom.( or being able to backup stock rom first). Took me about 5 days to find the right files and steps to get ota working again. Didnt help that i am a total newbie, the iconia is my first android device never flashed anything before except a pc bios. Do your research first and make sure you can go back instead of getting stuck. Here is a link to get you started http://forum.xda-developers.com/showthread.php?t=1155664 another thing when you go back to stock you also go to the back of the line in the update queue as well. I was on 3.2.1 went back to 3.1 got ota updates up to 3.2 but have not recieved 3.2.1 update again yet cheers.

[Q] K1 rooted 14_14 ROM

Hi
To be able to bypass the process of a flash to v13_13, open the backdoor, flash to 14_14 etc. can anyone point me to a rooted 14_14 rom?
In particular "K1_A301_14_14_120109_US"
Thanks

http://rootzwiki.com/topic/13407-alpha-ideapad-k1-cwm-stock-rooted-rom-120109-build/
Although still in the alpha stage, I switched from using timmydean's rom to this one specifically so I could successfully run the 14_14 rom and keep my root. Nothing against timmydean and his work, this just worked easier and faster. Also this rom add cwm which is the only rom out currently that does this for the k1, from what I've seen.
Just reemeber that this is still just an alpha, so be sure to read the post fully. Hope this helps!

Thanks for posting the link Dueces99. I compiled the CWM and ROM that Deuces99 linked to. I just wanted to add that there is nothing alpha about the ROM, just CWM. The ROM is stock and rooted and has no bugs (Other than the ones the stock ROM has).
The reason I left the Alpha status is because backup/restore don't work in CWM, and there is currently no key combination to boot into recovery. You must boot to recovery using the included app/widget

Right, there is no physical key combo. associated to booting into Recovery, the rom atleast provides the means to boot into recovery (widget/app) which atleast leaves the option. I personally, have not had any issues at all with this rom, and love the fact that all the bloatware misc. 3rd party apps and some Lenovo apps were removed, which made the rom seem that much more responsive upon first boot IMO.
Glad to hear that was of some help to you, kinda surprised there hasnt been anyother spinoff roms from this, regardless of its released stage. Just how cut and dry it is with flashing the 2nd newest update with root, then simply flashing the 14_14 update through CWM and keeping root. That was my biggest hurdle following timmydean's guide (and still is) was keeping root once taking the update from Lenovo.
Just my 0.02

so all i need is to flash alpha 3 and latest update 120109 in order to be on a rooted 14_14 build? can someone confirm?

Correct. After that you will be up to date and rooted.

Right, confirming with khanning88 flashing alpha 3 would be the 13_13 update. After flashing that, reboot into recovery via the Reboot Recovery app/widget included in the ROM, follow the instructions from there provided by the rootzwiki post and you'll be good to go with the latest 14_14 update. By far, the most cut-n-dry rooted ROM out there as far as I know. IMHO kinda deceiving that the ROM is listed as an Alpha (for CWM understandably) only because it's been extremely stable for me with nada one FC.
Wierd how an alpha build ROM is more stable than the OS that the K1 comes with...

From what I understand, it's the same firmware as the stock Lenovo, so maybe a little bit of a placebo effect? The CWM ROM does take out all the built-in non-Google apps, so maybe that has something to do with it.
I hope Lenovo gets its act together and shares out the proper source code so that some good samaritan out there can build a stock Android ROM to run on the K1. I've been using it a bit on the 14_14 CWM firmware, and it's still not as good as the firmware I've experienced on the ASUS Transformer TF101 or the Acer Iconia A500. The biggest issue I've found with the Lenovo firmware is that there is a lag closing out of apps and going back to the launcher, sometimes to the point that a forceclose-wait window pops up. I've not experienced that on the Honeycomb ROMs of any of those other two devices, so I wonder if it's because of Lenovo's customizations to Honeycomb, like the ability to close apps from the multitasking sidebar. In that case, maybe a more vanilla version of Honeycomb won't have that problem. Don't get me wrong; I think it's a great feature that Lenovo added to the taskswitcher. But I'd rather not have it than have the operating system lag. I trust Android's memory management enough to not really need to go manually closing apps.

Right, im sure all the bloatware taken out from Lenovo had to have some effect on overall performance. As far as stability between the two, maybe I meant to say "Wierd how an alpha build ROM feels more stable than the OS that the K1 comes with..."
But placebo effect or not, I've experienced zero issues with this rom even though I probably don't do near as much as other K1 owners with their tab. Lenovo does need to fix this, or preferably just provide full source to all...

Thank you so much, khanning, for all of your efforts. As I mentioned in this thread http://forums.lenovo.com/t5/IdeaPad-Slate-Tablets/K1-not-booting-after-update/td-p/548285 , your CWM firmware is the only effective workaround at the moment for those of us whose K1's are inexplicably locking up with "unrecoverable bootloader" errors to get onto the latest firmware.
We still aren't completely out of the woods though. In post 44 of your rootzwiki thread http://rootzwiki.com/topic/13407-al...-120109-build/page__view__findpost__p__390175 and post 47 http://rootzwiki.com/topic/13407-al...-120109-build/page__view__findpost__p__392343 , the users kennethrkennedy and aig787 both confirm that the "unrecoverable bootloader error" can still come back with updates, even through your CWM recovery. With your Alpha3 and your 120109.zip update, you managed to avoid updating whatever it is that causes the "unrecoverable bootloader error." This is my long rambling plea that, whatever you did there, you will continue to do for the latest update you are working on, so that those of us with these K1's that are prone to the "unrecoverable bootloader errors" can join the fun too. Thanks!

stock updating info

I had my tab rooted, played with roms etc etc
one day decided to try doing the bootloader and somehow
messed things up bad, locked it up totally and sent back

(thought they would have at least updated it) NOT
anyway went through all the over the air updates
still stock on ics version acer av041 a500 1.033.00 pa cus1
i know there is a newer version i have seen before but tab
keeps saying im up to date now
i really dont care about rooting (dont need to) but
my question is this...
is there a safe update.zip file that i can load and reboot
and update without rooting just run and stay stock???
i have found this page http://forum.xda-developers.com/showthread.php?t=1816560

ROM Support for the SM-T337T?

I have come across some very cheap Galaxy Tab 4's on eBay that I was wanting to try out. I'm a T-Mobile customer so I'm interested in the SM-T337T (band 12 support woo hoo!)
I see that there are recoveries for the tablet so it looks like I'm not the first to wonder.
Basically, my question is: which Lollipop/Marshmallow ROMs are currently supported and stable on the SM-T337T? And have we been able to reliably root/install recovery on them?
Thanks,
-coach

Unfortunately there are no custom ROMs for the SM-T337T. There has been an official lollipop update, and since there are working recoveries, you should be able to use chainfire's systemless superSU root method (you most likely need the systemless root because the lollipop update is 5.1.1). The fact remains though that nobody has made a custom ROM for this tablet. Sorry

For cyanogenmod you'd need a computer running linux, whether in a virtual machine or dual booting windows and linux (I have that setup on my Windows laptop, Ubuntu works fine), you'd need to set up your build environment, sync the necessary repos from Cyanogenmod's github, you may or may not (but probably will) have to create a device tree, but I imagine you can probably use moonbutt74's github repos to get you started on that, and once all that preliminary work is done you'll have to figure out what proprietary files are needed from the Tab itself. And of course it would be a good idea to download and inspect Samsung's source code for your device. If you have no idea what I'm talking about, this would be a good place to start reading: https://wiki.cyanogenmod.org/w/Development#Learning_To_Build_CM

Thank you for the very thorough response. I just don't wanna be "that guy" who gets on here and says "Waaahhhh the devs aren't supporting my device!" I'd rather help
When I get home in a few days, I'll fire up the build environ and see what I can do with her. Here's hoping no bricking!

I have that device on 5.1.1 and rooted it here(in case you haven't found this yet);
//autoroot.chainfire.eu/
Root available for both 4.4.4 & 5.1.1.
I would personally love to see marshmallow on this device! Currently settling for some Touch-Wiz debloating for now.

Does anyone have updates on this? I recently got an SM-T337T and would like to de-bloat it -- first on the chopping block would be TouchWiz. If there's a ROM that takes care of this, that would be nice, but I might be able to do it on my own?
Also, I'd really like 6.0.1, instead of 5.1.1 that's currently on it.

Hey Coach,
I know this thread is quite dated but just hoping you might have succeeded in either creating or finding a custom ROM for this device? I'm still using mine but finding more and more apps no longer supported on 5.1.1.

Lenovo TB3-850F root?

Just got this tablet today for around the house use light gaming watching YouTube and reading books on it but i can't find any info on this thing and what I do find is conflicting box says 1.00ghz on the 8inch website says 1.30ghz and a completely different cpu, mines manufacturer date was a month ago so I thought I had the latest model it has android 6.0 on it from the factory
Question is its pretty slow in basic games and Web browsing etc is there any info on rooting this or installing a rom allowing over clocking, I'd like to get the performance up a bit if possible.. I have noticed it cuts all cores off but one during some tasks and makes it come to a stand still almost so if I could root just to stop that I'd be happy

Kingroot, maybe?
https://kingroot.net/
I'd be hesitant, though; since it doesn't seem like there's any TWRP - and you'd def want a backup of the system before you root, or OTAs will be a nope.

kingroot failed, requested root and it shows 1 request so i doubt there is any root available for it right now its too new

Have you tried Kingo Root (via kingoapp.com)?
I was able to rooot my TB3-710F (Android 5.0.1 lollipop) with their windows version after a few attempts. Not sure if there was a trick to it or not. Have flashed back to stock and will try again to see if I can repeat.
Android 6.0 probably fixed most known exploits.

Hi All,
This is perfect thread, I was trying to find info on this Tablet, and there is hardly anything about it...
Has anyone managed to find / know, or get TWRP or CWM onto this device yet?? I was planning on picking one up tomorrow, but it all depends if there is a Custom Recovery available for it....
I see there is a custom recovery available for last years smaller 7" brother Tablet.... Please, let it be so....

On my TB3-850F I notice that Lenovo doesn't really add bloat to begin with. The non-standard apps can simply be uninstalled in the usual way. After years of using Samsung (Note, Note II, Tab 2) this is a refreshing change for me (on Samsung stock ROM the "extra" apps are baked in and can be frozen but not truly uninstalled; OK you can kind of uninstall them with 3C or Titanium but you can't actually reclaim any space so you might as well just freeze them).
Anyway I think a pre-rooted stock ROM is a good idea as there is no Chainfire Auto Root or similar yet and from the other forum posts on this device it's clear that people struggle when using adb and fastboot and TWRP if they are not already familiar with these kinds of tools and environments.

Lenovo is certainly more sparing on the bloat than manufacturers like Samsung for sure, not to mention all the bloat that comes pre-installed on the bulk of carrier branded devices. There are several Google related applications, however, which are baked in. With deodexing, lib removals, app data and app cache, I have been able to free up nearly 500 MB of space, leaving the end user with a bare bones Google infrastructure -- Google Play Services, Framework, Play Store, etc. More and more Android enthusiasts are becoming focused on privacy, and are steering away from all the Google centered applications.
Yeah on root I'm including a patched boot image for full systemless root support, using @Chainfire's SuperSU v2.79 TWRP flashable zip. I've made a couple of stability tweaks to the TWRP custom recovery already available for this tablet as well.
Oh, keep in mind on this particular MTK Board Platform and partitioning index, the /system image partition is allotted to 3.0GB. With bloat removed and some cleanup, the /system partition can be re-sized to 2.3GB using ext4fs, leaving 700MB to be carried back over to the /data partition.
