[ONE Q&A, Help & Troubleshooting] Michiel0211:
XDA,

I am trying to root the stock rom (Cyanogen OS 12.10YOG4PAS1N0). I have thus far managed to unlock the bootloader and am now trying to install a custom recovery - here I run into some problems:

So I downloaded the latest TWRP and renamed it recovery.img - pressed 'fastboot erase recovery' and then 'fastboot flash recovery recovery.img' -all going fine.

I then unhook the phone, turn it off - press volume down and the power button to boot straight into recovery (not even booting OS) and here's where it gets interesting:

The 1+ logo appears, as if its trying to boot recovery - it hangs for 10s, then the screen goes black and it vibrates. The 1+ logo appears again and it boots straight into OS.

If I keep pressing volume down I am in a loop like this, with 1+ logo, screen black and so on.

So I never actually get into the custom recovery. And if I boot into the OS and press restart into recovery: I get stock recovery.

I've tried CWM. TWRP, Philz, the toolkit, manually - lots of things. I turned off overwrite custom recovery in the developer options - all to no avail.

I hope someone recognizes this problem and can help me out.

Thanks a million,

Michiel.

Not sure if this is your issue, but go to this thread on how to unlock bootloader, install custom recovery and root. See the note in underline at the bottom of item #2, installing the custom recovery. I was unable to get TWRP to stick until I followed this simple method.
[ONE Q&A, Help & Troubleshooting] Michiel0211:
Yes, I tried this but when I power the phone down and boot it with the powerbutton and volume button - it hangs on the OPO logo and reboots again into the OS.
[OnePlus 2 Q&A, Help & Troubleshooting] rohil69:
Hi all,

I am having issues connecting my OnePlus 2 to my windows 7 using the original oneplus type c usb cable. Whenever connected the phone is charging only. No option to select any mode what so ever.

I thought it may be drivers or OS issue, so then I tried connecting with my MacBook Pro but it's still the same.

USB debugging is ON. Even installed android SDK, platform tools, Android File Manager on Mac but nothing changes, it's Charging and shows no devices in Android File Manager as well as Terminal adb

Settings > storage > USB connection option says to make USB connection to PC even though it's connected

[OnePlus 2 Q&A, Help & Troubleshooting] JerryK132:
In my case after scouring the internet and discovering the many people who'd tried several cables and still can't get any PC to recognise their OnePlus, I suddenly had an inspiration: Could it be fluff and other debris in the socket? So I powered down my phone (VERY IMPORTANT! SWITCH IT OFF FIRST), got a pin and very carefully scraped the inside of the USB-C socket on the phone. I scraped very carefully either side of the tiny contacts tongue in the centre of the socket and an enormous amount of pocket fluff popped out. After several scrapes and after blowing it all away, I plugged a cable into the phone.

For the first time in years, the cable "clicked" in properly (and did not fall out!) and the PC immediately responded recognising the phone! After that it was simply a matter of clicking on the "USB for Charging" notification and selecting "USB for File Transfer" and all the folders appeared. What a relief!
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] visi6630:
Hello!

I have an unlocked sprint note 4 which I use outside the USA as a GSM phone with a sim card.

So far so good.

The problem is that this phone being produced for sprint does not connect on 4G.

I have been reading about the possibility to change the NV values to be able to add LTE bands to the phone and I was able to change those values but still no luck.

In my country, the 4g network works mostly on bands 3 and 7 (1800 and 2600).

I am starting to think that probably the sprint version might have differences in hardware with other 4G capable phones.

Can anybody tell if there are any hardware differences between the sprint note 4 and other note 4 models.

Do you think that the sprint note 4 has what its needed to connect on 4G on the above frequencies?

If yes, what might be the right approach to try to resolve this.

Thank you for reading and since this is my first post on XDA please help me!
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Marq221:
Yes, because of Sprint Spark it only uses 26 and 41 bands, 1900mhz and 2.5ghz respectively. FDD-LTE and TD-LTE are unique to Sprint and they are big enough to have the phones shipped this way. For flexability yoh should move to a GSM model phone.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] spinxus:
Heh, what you think about this thread.

Especially about the history of success adding LTE bands 4/14 in SGS5 SM-G900P from Sprint?
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Marq221:
Its worth giving a try for sure. You do run the risk of bricking your NV and losing signal altogether. However, I have done this successfully using DFS CDMA Tools on an old Samsumg Cappy from AT&T back in the day. *Disclaimer: proceed at your own risk*
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] Marq221:
After further review, and some trial and error, the above listed mod only works with GSM phones. Your Note is a CDMA version. Please do not try.
[Sprint  Galaxy Note 4 Q&A, Help & Troubleshooting] visi6630:
I understand but since my note is a CDMA how can you explain that it works fine for GSM and data in 3g ?

What might be the hardware difference with the international version that does not allow my phone to work in 4g in my network?

I am assuming that they use the same chip-set and the problem is only soft based.

[XDA Assist] Sakib56:
So a couple of days ago I dropped my phone (Huawei Ascend Mate (MT1-U06)) ... no harm done, I've dropped my phone plenty of times and it was fine but this time it turned off. Originally I though I broke it, I go to turn it on and it just keep restarting, turns out it's 'Boot Looping'.... I think. I've searched online and I was told to hold down all 3 buttons and enter go recovery mode and put SD card in with some software. Not really sure what the software is, but I bought an SD card and an SD card reader and I'm ready to fix the device!

Just to see what would happen, I went into Recovery mode and it said this:

USB Update Enter...

This phone is secureboot phone.

This phone is LOCK state.

Any help?

LineageOS 16, changing dpi did nothing. Solved by creating a custom vr viewer profile with values x2.62 higher than actual.

Edit - this scale solution producing weird results.

Found better one: edit build.props

Find ro.sf.lcd_density in build.props and set to 406

After that, to restore ui scale, change dpi to 480 from any dpi changing app.

Now it is possible to use VR profiles as usual.

[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] engineers.mech:
Hi there

I've faced a problem since. I lose my antenna signal (on both 3g & 2g or auto connect) frequently, then when antenna signal bars return, suddenly screen flashes to black and back then I lose antenna bars again. and this happens for a while till it gets restart almost every time this happens.

I see multiple wired things also; while screen flashes,

sometimes some apps would stop working like instagram, battery docter, goole & google gesture and ...

sometimes i see a notification stating my sd card is damaged and needs format! (some times sd card is empty!)

and like that...

while restarting when samsung logo or even note 8 logo comes up, I see these flashing screen continus

I guess these happens while I am at areas with not very satisfying signals, although I had this problem while I had no sim card in it too!

what is wrong guys?

Sudden signal drop, screen flickering, rebooting without prompts. After that the apps installed in the sd card wont load for most of the time.

Plus device overheating and battery draining (did the battery pull trick and have been doing ever since, sometimes 2x a week!).

really hope somebody could chime in for a solution.

PS, thinking of flashing new ROM, but havent decided which one yet. Will this help at all?
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] gooberdude:
Donno... I know if the battery is weak or bad, the screen will flash randomly when power is needed. Example 1600mhz is used durring boot and home screen loading. As for non wifi connection for data, that will consume power like the CPU running at max.

It may be time to replace your battery. Especially if you have pulled the plug a few times. The wires and plug are brittle. Found out when messing with the used Note 8.0 I got on ebay that had 4.4.2 loaded.

[AT&T Galaxy Note 3 Q&A, Help & Troubleshooting] Zenoah:
My note 3 was rooted on oc1 for a few months, then about a month ago it started randomly rebooting during the day. Sometimes it would boot normally, other times it would bootloop until i cleared the cache multiple times. I then went into safestrap to clear the cache and dalvik, and that ended the random restarts for about a week until it started happening again. To make sure it wasnt the sd card, i swapped sd cards and even removed it entirely, still was getting random bootloops. I got rid of the root and reverted to 100% stock oc1 using the 4 odin tars, then i upgraded to oc2 stock. Still, i am getting bootloops even on a stock rom. What are my options?

[Xperia Z3 Compact Q&A, Help & Troubleshooting] theduardo:
Hey guys,

I've recently bought a z3c and so far I'm happy with it. Got this issue though. Sometimes when I'm browsing web, replying to a text or doing something else, the phone closes everything or opens the recent apps tab by itself, as if I clicked on the home button or the tabs button. This is pretty annoying when I'm in a hurry to do something, because it makes me have to open everything again. Doesn't happen everytime I use the phone though, just sometimes.

Has anyone got this issue also? Would it be a software issue or a touchscreen issue?

Any help would be appreciated.

[Nexus 5X Q&A, Help & Troubleshooting] dwang:
I've been experiencing random lagging with my nexus 5x and I just noticed that the stock nexus 5x kernel implements zram.

Here's screenshot:

For those that don't know, zram is basically a compressed in RAM swap space.

Everytime the kernel saves to and from zram, it has to compress/decompress the contents and that could be the source of some of the lag people are seeing.

https://en.wikipedia.org/wiki/Zram

I plan on rooting my phone as soon as I get my usb c to usb a cable and disable zram and see if that helps with the random lags that i've been experiencing.
[Nexus 5X Q&A, Help & Troubleshooting] starrzo:
Very interesting theory....I am experiencing lag too with my 5X. It is very frustrating to compare with my two year old Nexus 5 which performs lightening fast and noticeably smoother.

Keep us posted when you root and disable zram :good:
[Nexus 5X Q&A, Help & Troubleshooting] dwang:

[Nexus 5X Q&A, Help & Troubleshooting] starrzo:
Good point.... Can anyone confirm is zram is enabled in the 6P?
[Nexus 5X Q&A, Help & Troubleshooting] PhilipL:
Hi

That's not the reason. Swap space takes up memory! The reason it is added is because it protects the flash memory and improves performance. Rather than having the swap drive all on flash memory, it is compressed and kept in RAM (because 2Gig is plenty), this improves performance because any pages swapped out are swapped to DRAM which is considerably faster (and uses less power), and saves lots of small writes to the flash memory, which stops it wearing out.

Google and LG haven't just thrown the Nexus 5X together without knowing what they are doing :)

Regards

Phil

seems like the encryption is the source of the bottleneck. the encryption with no easy way to disable. i cant wait till sources are released and i can get off android.
[Nexus 5X Q&A, Help & Troubleshooting] dwang:
That makes no sense.
[Nexus 5X Q&A, Help & Troubleshooting] PhilipL:
Hi

I've disabled encryption (so I could root it) and the phone performs identical, besides I'm not seeing any lag or problems. Only user data is encrypted anyway, it's not the whole device that is encrypted, so any performance loss is negligible as it is only a tiny amount of data that is going through a decrypt/encrypt process.

The Nexus 5X is as fast for me as the graphical animations allow, if people are seeing lag have they tried a factory reset, leaving the phone to update all the apps without choosing to restore previous apps/data and trying the phone out? It could be an app problem/service that isn't compatible and eating CPU cycles.

Regards

Phil
[Nexus 5X Q&A, Help & Troubleshooting] m4r0v3r:
I remember ZRam being used in the Jolla phone by some of the community, and in that instance it actually improved the performance.
[Nexus 5X Q&A, Help & Troubleshooting] dwang:
My experience was the opposite. Back in the g2 days there were roms that enabled zram and it was smooth at first but then it got laggy after a few days.

I'm coming from the nexus 6, and the nexus 6 is smoother than the nexus 5x. This is in terms of input latency, scrolling, and load times.

It may very well that I have a defective phone, but a lot of other people have reported these issues as well. If you aren't experiencing this, more power to you, but don't disregard other people's experience.
[Nexus 5X Q&A, Help & Troubleshooting] starrzo:
Whatever the cause is, I've got this problem and I'm considering returning it as faulty and using my Nexus 5 for another year or two, because it's really bugging me now.
[Nexus 5X Q&A, Help & Troubleshooting] kdoul:
Why there should be any swap space in the first place? Zram does indeed improve multitasking on systems with limited amounts of ram but there should be no reason to put it on an expensive device with "plenty of ram". Zram comes at a cost, cpu power and usable ram that is. If you do multi task a lot it's going to use more resources than necessary to keep up. If you are using an app that requires lots of ram it will slow your device down and cause a lot of heat because it is compressing/decompressing active pages. This is the reason most reviewers report that 5x is slower than the G4 (that has 1 more gb of ram) even though they have the same SoC.

It's the same Nexus 9 story all over again isn't it? Once again they used the absurd amount of 500+ MB which will cause the Low Memory Killer to kill everything except for the foreground app because there is no free ram.

But why did they do that? The 64bit android builds consume much much more ram than 32bit. If you disable zram on nexus 9 you will notice that it heats up much less and that it is faster with ram hungry applications but apps start dying even faster. Chrome will crash even with 1 tab open if the website is heavy. Launcher redraws will be everywhere. So we go from borderline usable to absolutely terrible.

I think they should have used 32bit builds on their 2gb devices. They would be faster and much more usable. There are no immediate benefits with 64bit anyway...
