[Android Q&A, Help & Troubleshooting] raffss:
Hello!

After searching Google and trying various methods to root and install custom recovery to the Xgody Y20 (MT6580M), I decided to share the way that I do it, the idea is to stimulate development for this device. I was able to boot a cyanogenmod 12 ported rom following tutorials for other devices with the same chipset, however, with many bugs, it was only a test. The custom recovery image that I've ported to Xgody Y20 is available on the links below. (Recovery ported from Wiko Lenny 2 because it has the same MediaTek SoC MT6580M).

TESTED ONLY ON XGODY Y20 device!!!! Do not use these files in other models, you will probably brick it!!! :crying:

- Model: Xgody Y20 (MT6580M) (with SdCard inserted)

- ROM used during process (Stock): V5_80L_WE_3GW_B15_EMMC_64_8_QHD_TXD_T3_D_XGODY_20161216 14.02

www needrom com/download/xgody-y20/

**** Do at your own risk, I'm not responsable for your device **** ;)

Download necessary files: (Dots from links are removed, new user :eek:)

- ADB Drivers: devs-lab com/usb-adb-drivers-for-all-android-devices html

- Kingroot: (search google)

- Flashfy from google play store.

- Recovery image ported to Xgody Y20 from Wiko Lenny 2 and stock recovery if you need it:

drive google com/open?id=0B_mTcvpzMmQ6OTBUcERKU2ZoZGs

Procedure:

1 - Install ADB Drivers

2 - On phone go to Settings -> Developer Options and check Enable USB Debugging (Enable Unlock OEM bootloader option, I

don't know if it's needed)

3 - Install kingroot, launch and root the device.

4 - Copy downloaded custom recovery image to sdcard (or flashfy directory :confused:).

5 - Open Flashfy app on phone and flash downloaded ported file to recovery.	(Another option is to flash recovery with Official TWRP app from google play store)

6 - Shutdown device and power on holding POWER and VOLUME+, from menu select recovery and press VOLUME-, TWRP recovery screen should appear at this point. :cool:

7 - Make a backup of all partitions to sdcard to restore it in the future if you need it.

If there's anyone who find how to correctly port a CM ROM to Xgody Y20 please share with us. That is all I know for now. I will do more research on porting roms later. :good::good::good:

Regards.

[Lenovo Vibe K5 Plus Questions & Answers] LHARC:
Hello fellows, first of all, I would like to thank you all for the great materials I have found here.

Great community, thank you guys :highfive:

I have a problem with a sensor which I believe is the accelerometer, I really like using VR on K5.

But I have a bias "drift" problem, and whenever I'm using it feel like it's moving to the right side.

I'm using the rom aokp_A6020_nougat_nightly_2017-01-06, My question is there are some tool to perform the calibration of the sensors?

I've basically used almost all the apps available in the playstore and none solves this problem, It is as if the calibration has not even been done.

In the rom stock there is an option (hidden menu) or in the recovery to calibrate the sensors, but i'm using the custom rom AOKP

Can anybody help me? I really want to use the VR, but currently I get sick if i try with the bias problem..

If theres no tool to fix it, how can i erase all the data from the accelerometer/gyro sensor and get clean ?

I think I ended up making the problem worse in the stock rom.

Looking in github, I found something related to this a calibration manager but i don't know how to access it.

[Google Pixel XL Questions & Answers] PsiPhiDan:
I have read countless reviews for this phone and most say one of two things about the SoC:

(1) It's got an 821 so no wonder the phone feels faster than other flagship phones from 2016.

(2) It's got an 821 but has been underclocked so it has the same speed has an 820.

Upon researching, there are two variants of the 820 AND the 821. My question is this though: is there ANY difference between the higher-speed (I believe more common) 820 vs. the lower-speed 821? I know they're clocked the same, but are there other factors such as efficiency or something else that differentiate the two? Otherwise, I have no idea what the point of naming it as an 821 is.

I keep seeing people bash Google for using the lower-speed 821 but I'm sure there's much more to a chip than the clock speed and I'm sure Google didn't use it for no reason (versus the standard 820). Anyone know any details to differentiate these two? Any benefits of 821 (lower) vs. 820 (faster)? Thanks!
[Google Pixel XL Questions & Answers] old_fart:
Ugg. If you google "820 vs 821", there are several things to read and see. . . . Short answer - yes the 821 has more than just the clock bump

.

oh, btw - if you use [MENTION=4684315]flar2[/MENTION]'s replacement ( I like it alot . . . )

https://xdaforums.com/pixel-xl/development/kernel-elementalx-pxl-0-02-t3487072

you can get back that clock speed boost,

( hope this helps )
[Google Pixel XL Questions & Answers] PsiPhiDan:
I Googled MANY different combinations of these things before posting here. Found nothing but superfluous garbage and press releases skimming over all the details I was after. Most pages only compare the 821 (faster) to the 820 (faster).
[Google Pixel XL Questions & Answers] cmhjr:
There are two versions of the 821 which is an enhancement of the 820. The 821 includes improvements for camera instructions that Qualcom made and also slightly increased the GPU speed over the 820. Also the 821 has improved Snapdragon*VR*SDK for 3rd party developers and overall more power efficient then the 820.

Qualcom did this in the past with 801 being an enhancement of the 800.

[Google Pixel XL Questions & Answers] PsiPhiDan:
That's exactly what I was looking for. Thanks, again!
[Google Pixel XL Questions & Answers] nabbed:
I may be mistaken, but I believe Anandtech did a complete review with benchmarks. And the improvements were on the order of 5% compared to 820.
[Mate 8 Q&A, Help & Troubleshooting] KarKzas:
Hi, I know this should be a lame or noob question, but there is:

I have a Mate 8 NXT-L09, compilation NXT-L09C521B138, which is from Movistar Latin America (vendor=telefonica, Country=la). It came with some preloaded apps, customized boot animation, and some system configurations I cannot modify (such as SMS gateway, so I can't send any SMS). I want to install some "clean" compilation, and I looked up the compilation of a stock phone in a Huawei Store of my country, and it was NXT-L09C605B100, and it comes without any custom configuration.

So, my question is: Can I install any CUST compilation to my phone? or I'm stucked in the "C521 Series" compilation? is there any compatible list or something like that?

Thanks a lot, any advice would be apreciated. Sorry for my bad english.

[SuperSU] gottlasz:
Now i could open the recovery log.

Unfortunately this part means that even if it's a 3.0.2 TWRP something is missing:

"- Found boot partition at: /dev/block/mmcblk0p5- Dumping & unpacking original boot image...WARNING: linker: /tmp/boot_repack/tools/armv7/unpackbootimg: unused DT entry: type 0x6ffffef5 arg 0x560"

Maybe you should try with a newer version of TWRP if there is one.

Or if you follow my older guide which was a manual unpacking and repaking with carliv image kitchen, that could work.

Check my old guide: https://xdaforums.com/lg-k10/how-to/twrp-root-lg-k8-k350n-t3475807

Anyways give me until tomorrow, ill take a look at the script maybe i can avoid this error.

It avoid for me" Error: Unpacking boot image failed!- Aborting..."

Works like a charm!!! thanks to gottlasz and XDA group!

sorry for my english
[SuperSU] Chainfire:
You should recompile all the used binaries as static, that should avoid a lot of issues.

Also, don't bother with older Samsung (everything before S3) and older Sony devices (not really sure until when). These use non-standard boot images that are very tricky to patch without outright recompiling. It can be done - I have done it in the past - but it is a major hassle and very errorprone.
[SuperSU] gottlasz:
Thank you Master!

I know about the compiling situation, however the problem is that i did not compile anything since the whole stuff is based on jcadduono's LazyFlasher. He compiled the binaries I only tweaked the script and added some stuff... i don't have the resources to compile. Now i'm collecting static binaries to exchange them in the installer in order to solve these compatibility issues.

Basically i just wanted to help some of those unfortunate as me who has lz4 or other compressed ramdisks and unable to intall SuperSU. Well..., at least a handful of them.
[SuperSU] gottlasz:
New version is up. A few TWRP related compatibility issues are solved.
[SuperSU] haris1976:
i test the new version but no luck

this is the recovery log
[SuperSU] gottlasz:
How far does supersu intaller goes?

I mean can it unpack your boot image?

Install only supersu and make a recovery log please.

I tried to unpack your boot image with carliv image kitchen and no luck...

I think supersu can't even unpack your boot image and then there is no chance to install it. Even if we could change the ramdisk compression...

Are you sure supersu intaller gives you the same error message as it is stated in the OP?

I believe you have a non standard boot image as chainfire talked about.

CM file manager is very buggy still - try deleting a directory named ".android_secure" from your sdcard if it exists (but you will need different file manager to do this, others will work)

"Dirty install" over the old version, even if it's only a nightly from some day ago, does not work on my n5100 at all: i get an error: 7.

Completely "clean install" means, as i understand it, wipe "system" and "data": this means installing all apps and making all setting again, which is a pretty tedious job.

That's why a "

half clean install"

is my preferable thing: wipe "system" only. No installing/settings again after the update ;)
