MeMO pad Me176cx noob rooting questions - MeMO Pad 7 Q&A, Help & Troubleshooting

I just picked one up and trying to learn why I would want to root, never did it before.
Currently it is running ww-3.1.23.124.
If I run all the OTA updates to the latest version would I still be able to root?
Thanks! [emoji1]

Can I upgrade it?

No one? I'm just going to upgrade it.

Upgrade to ww-3.1.23.158

Are there some firmware that are causing issues? It found another update but I don't want to install that one because I read it will drain the battery faster. I'm not sure what the next upgrade is. Should I just root it and keep it on this firmware or is it worth it to keep upgrading it andthen root???

The latest and most stable lollipop is 33 and you can root that one no problem. Although, I believe xposed isn't working for that one yet. My tablet is much more stable with 33 and battery drain isn't an issue.

[Q] Root, remain stock and still have OTA?

as the title says, is it poosible to root the XZ and still receive OTA?
I just want a rooted stock rom/phone with minimum fuzz and receive updates from sony(whenever they arrive).
No you can't, but the rom devs here are great and most of the time when a new firmware is pushed by Sony within a week or two you should be able to flash the update for whichever ROM you are using.
Sometimes that's a good thing as the two weeks allow you to find out if any new bugs are introduced.

You might have misunderstood him, it sounds possible to me, if you have a stock rom and you root it you should still get ota updates right? As i understand it its the only way to update and keep root.
Yes, you can root and stay stock. I am set that way on my Nexuis 4 and I true updates. Both TWRP and CWM will keep root. SuperSU also has a survival mode.
If I ha e time this weekend I will root the Z.

Yup. In fact, even on the S, that's one way you upgraded the OS but kept root - You would let the OTA do a standard upgrade on top of the rooted OS, and root was maintained.
As the updates are released, I'm sure we will see if or how this will continue to work.

excellent, for now I`m more than happy with the stock ROM. I think that Sony have done a fine job not to do so much! so it doesnt feel bloated.. had it been a samsung I`d have to change the rom just to get rid of the touchwiz..

Flashing 4.2.2 over 4.3

Hi guys,
I just want to ask if it is possible to flash any 4.2.2 Rom over a 4.3 one without changing the Bootloader or Modem (as far as I know kernel there are no other things updated in 4.3 except some features in stock Rom and kernel). I'm sorry if there is a thread like this one out there but I couldn't find it on my phone app
Thanks in advance for your time and help

Now why would you do that? It's like installing windows ME over Windows 7

It's because I like to have all the possibilities to personalise nz phone, and Roms like MIUI won't get 4.3 support in the next time it's just my opinion

4.3's stock kernel sucks hard. I've experienced "unexpectedly closed" errors with certain apps and the device sometimes reboots itself without apparent reason. Had to flash the latest franco's nightly kernel in order to get this faulty release somewhat stable.
Nice GoinGoogle.

It is possible with custom recovery, not possible with fastboot without updating the bootloader. You may use any modem. You need 4.3 kernel.
EDIT: my bad, it was other way around. Yes, it is possible.
4.3 stinks like hot garbage. I'm not upgrading, and I'm going to downgrade my new N7 to 4.2.2 if possible. 4.3 is like windows ME.
I still have 4.2.2 on my N4 and have only tried 4.3 on my Kindle Fire. From my experience I have little interest in upgrading my N4 for the time being, since 4.3.x will likely fix all the JSS and JWR issues.

I think your problem is caused by your usage pattern / apps which are not updated for 4.3, combined with unstable root. Don't blame Google unless you experience the same behaviour on unrooted stock.

Wrong.
I experienced those crashes while on stock, even with google applications. that's a faulty release, not faulty device nor usage. for god sake, even "settings" menu has "unexpectedly closed" on me once.

I have had totally different experience with 4.2.2. To be honest I didn't like it at all. I didn't find it as "rock solid" as many other users here. (I came from Galaxy Nexus. Android 4.2 compared to really rock solid jzo54k 4.1.2 was imo buggy as hell. It didn't bring any performance boost but rather did the opposite: BT, WIFI issues, mem leak etc.) Plus I found this low touch sensitivity extremaly irritating. I use rooted stock 4.3 and so far I haven't noticed any bigger issues. Even if I do I really don't see a point to go back to still buggy 4.2.2. I think my device performs much better on 4.3. Maybe it's just a placebo effect, but it feels snappier and smoother. Just my subjective opinion.
Of course I do understand people that miss their favorite custom roms, whose 4.3-versions are still unavailable.
4.2.2 had and has clearly wifi/bt issues (major data stalls, difficulties in re-enabling bt after 20-30 hours of uptime).
These issues were solved. however, I'd expect 4.3 to be as stable as it can be, especially when it took more than 5 months for its release. Unfortunately, that's not the case. not even close, which is rather embarrassing.
I really was expecting for iOS-like smoothness and stability by now.

Maybe that's been your experience but my experience has been the exact opposite. It's made my N4 even more of a pleasure to use. It's smoother, snappier, and battery life is amazing. Mind you, I've never really had any problems with 4.2.2 except maybe GPS locking problems, which 4.3 solved. The only real problem with 4.3 is this whole JWR/JSS nonsense.

Not sure what's going on your end but my phone has been rock solid with no FCs at all since upgrading to 4.3 using the factory image (I never go the OTA route)
In case you're both running a stock 4.3 (unrooted), you're more than welcomed to run "angry gran run - running game" by ace viral and watch it boldly & proudly crash. If not on beginning, after few minutes. Just only one example out of many.

Not sure if this is the right place but here goes.
I am on AOKP milestone 1 might update to milestone 2 soon. But what do I have to keep in mind when making the jump to 4.3? Will I be able to downgrade later without problems? I dont understand the modems and bootloader stuff. Plus if I flash 4.3 I will lose root, so how do I flash 4.3 without loosing root? do I root the phone again after flashing? or is there a shortcut?

You can flash a 4.3 rom in recovery, but its recommended to flash radio and bootloader in recovery.

Android 4.3 ROMs require radio version .84 (or a hybrid 27/84 or 33/84 radio) and bootloader version makoz20i. As Thibaultvw points out radio version .84 and bootloader version makoz20i are both available as flashable zip files and should both be installed before installing a 4.3 based ROM. In addition, Android 4.3 requires SuperSU version 1.51 for working root privileges.
After upgrading the radio and bootloader for Android 4.3, you can restore or install an Android 4.2.2 ROM without changing the bootloader or radio.

Give it a hard go bud lemme know how it works!

[Q] Nothing will get my IMEI working on CM! Different /efs folder files!

Ok guys, so here's what's happening... I have tried every method I could find online in order to get my IMEI to be recognized in the CM11. At first I tried it with the CM10.2 to no avail, and now I am failing with the latest one.
When I rollback to 2.2 or 2.3.3 my IMEI starts working again. HOWEVER, even with these stock versions, my efs folder contains a DIFFERENT set of files inside. In particular I have one file LESS (I think). It is the nv_data.bin. I do not know why I don't have that file, nor why my IMEI works without it!
But the point is that I, then, cannot use that "stock" efs folder to replace the new one created when I flash the CM11! Do you see my problem?! What should I do?! I really don't want to keep the 2.3.3 having experimented the CM11! I am sending a printscreen of my "backed-up" efs stock folder with hidden files enabled to see if anyone has an idea.
Please help me out! I am desperate here!
PS: MY model is the i9000b (from brazil) which is why I do not have a stock 2.3.6 (I think).
Go back to GB and then upgrade to KK in steps.
GB/ICS/JB/KK
I know some people haven't had any problems with jumping straight to KK from GB, but the only ever time that I personally lost my IMEI was when I was on GB and installed JB, missing out ICS...

Thanks for the suggestion. I might try that in the future, I'm kind of sick of rolling back and flashing over and over again for now. The good news is that my problem is (partially) fixed. I went back to KK (CM11) and still don't have IMEI but I can call and get calls again. It turns out my stupid carrier had blocked my SIM for some reason, so at least now it's useable again!
But my battery is being eaten like it's candy, though...

After installing which ROM?
Download betterbatterystats, it will tell you what the problem is. What does even settings>battery tell you is using battery?
To help someone information is required, not to be told 'it's not working!"

I've got a nightly CM11 for I9000B running. The battery tells me it's the screen (34%), the Android System (20%) and then surprisingly a game I play not as often as the 10% would represent. I already have my brightness lowered to half and still my battery seems to be getting worse and worse.
Going to try batterybetterystats and get back to you now!
Ok so batterybatterystats is paid :/ Any other free suggestions?
How long is your full time from a charge, and how much screen on time?

Downgrade to kitkat from lollipop

Hi
i can downgrade my note to kitkat from lollipop without any problems?
I made root in lollipop...
Thanks
Yes, just have to find your phones kk firmware and flash through Odin.

Ok
what the best stock version of kitkat to get the best battery life?
I install the israeli version and i get same battery life like lollipop
thanks
I would highly recommending installing the stock version of KitKat that is released for your country.
Yes, i've just done this myself. I got the phone last week, and in amongst all the other 9 million pop-ups that Samsung provide, I accidently pressed yes to upgrade to lollipop.
I ran it for a day and the lag was terrible, so I have now gone back to KitKat. As above, I just went for stock for my country. It seems a lot better now. Once they release another lollipop patch i'll update. It's a shame, as I still think my htc one m8 is slightly faster. It feels more responsive. Anyway, thats off topic.
As above, just use Odin. I'm new to modding Samsung devices really, but managed it easy enough following the various guides around.
Did you guys have to factory reset your device after the downgrade?
If so, does the Kies application backup function safe the application data (logged in accounts, safegames, application settings etc.) too?

how do I update to Android M OTA without losing my data?

I updated to LMY48M without losing data even though I am rooted by flashing the stock image from this post http://forum.xda-developers.com/showthread.php?t=3066052
well I be able to do the same with the Android M update?

Hard to say since the official release hasn't happened yet. It's my understanding that the Dev version your on now isn't totally functional, I read that a few things aren't available until the official version is released. I'm sure a Dev will make it happen, it's just a wait and see thing at this point.
Worst case scenario is flash back to stock without flashing user data. Then you would be clean system wise and would get the upgrade ota. Then reroot.
The issues and solutions for final M will be no different than any other update.

No because you can't OTA if you're rooted. There's a thread about this in general.
