[Q] My M8 turned sucks after lollipop update..

I rooted my m8 on stock android 4.4.4 and since the lollipop update rolled out, I applied my backup from TWRP and flashed stock recovery then relocked bootloader. Installed Lollipop via OTA, unlock bootloader and flashed TWRP then flashed supersu. So I'm on android lollipop 5.0 and rooted. I don't know what went wrong, my phone seem too laggy ( mostly when I'm trying to type on facebook messenger, every times i type a text it stacks for some times) And most importantly, some stocks application such us HTC sense TV and Scribble not working anymore. every time I open, it say " stopped unexpectedly ". I don't really know what I might do to get it fix, please advice me.

I have the same problem, basically. I have an unrooted, completely stock phone that got updated through OTA. Ever since the update the phone is lagging, the battery life is visibly worse, and the only visible change is the color of the quick settings and the appearance of notifications. Lots of people are excited and eager to update to Lollipop, but based on my experience I really regret updating. I wish there was an easy way to revert to 4.4.4, but unfortunately it takes too much time which I don't have at the moment. So I decided to wait till May, when Sense 7 is supposed to arrive to M8.
Many of the initial problems with Lollipop were solved by factory reset, but certainly not all. It remains to be lagging and frustrating. At least it's free. But on the other hand, if I bought it, I would certainly return it and ckaimed a refund. As it is, I just have to suffer through it.

ႈI guess, there only way to switch back to stock totally is to s-off but I am not sure if we can still apply nondroid back up of 4.4 stocks might work on lollipop loaded device. its so annoying ^_^

Facebook and Facebook Messenger simply have issues. The big problem is that when sounds are enabled in those apps they lag terribly running ART. ART is probably the reason why you're having issues with other apps, which would be remedied by a factory reset and reinstalling all the apps. I don't see any reason why you'd need to be s-off to flash back to a nandroid backup of 4.4. The only possible issue I could imagine you having would be compatibility issues with firmware, and I think that would require you to be s-off to revert back to, but I think 4.4.4 should work with 5.0 firmware. Can't say for certain though since I'm on Verizon and I'm not sure what carrier you're on, but I'm running 5.0.1 on 4.4.4 firmware. I've run several Sense 6 5.0.1 ROMs and they have been just as fast and even more battery efficient than 4.4.4.

You could always flash a Kit-Kat ROM while you wait for Google to address those bugs with the next release. You don't have to S-Off to go back to the older firmware if you don't want to.
If you want to stay stockish, I recommend Maximus HD.

My phone is turning worst and worst, now i can't even screenshot due to luck of storage it says. So I don't have to s-off to roll back ? All these issues are due to Android L or could it be becoz of me, I flash old TWRP ( 2.7). One more things, I do I flashed my local font on HTC ? I use all fontchangers and I even flash it via fastboot but it doesn't seem overwrite. I can't install busybox too.

Most of your issues are not Android L related but more on user side. Make a backup of your current ROM on ext_sd, make a backup of your internal storage to ext_sd or PC.
Change your TWRP version to 2.8.5.0
In TWRP select WIPE then FORMAT DATA - yes
Reboot recovery
Restore your backup

How ? Have you managed that ?

for me on lollipop on the m8. lot of features did not seem to work. like the nfc, screen rotation, g sensor, flashlight, and proximity sensor. so i tried to goto a custom rom and it still didnt work. anyone else have this problem?

For lag removing, disable Nu player in developper options.
As per the rest.. my M8 kicks ass using completely stock lollipop 5.0.1
No lags, no FCs, no misbehaving.

No issues here since I jumped to Lollipop. Then again, I'm technically not stock. I'm on Viper Rom.

I tried that and it still lagging on keyboard then I flashed Revolution HD and same issue. Lately, I found out that comes from Fb messenger, I keep in app sound alerts off and now my keyboard is flawless. I'll just wait for 5.0.2 to go back to stock.

For me, its all becoz of TWRP 2.7. TWRP 2.8.5 going smooth on lolipop M8.

Set up 5x as new Device or from Previous backup? (to best improve poor performance)

Hello,
My 5x became more less unusable so I had to factory reset it. Will setting it up as new device be more advantageous in terms of performance? Or should I stick with the backup and save my self a lot of time downloading everything?
I had this phone since it came out and I think I will be getting rid of it. It became laggy as hell and 2gb of ram just does not cut it, and now since I just upgraded from 6.0 to 6.0.1 my build number is MTC19V and for the life of me I cant find a way to decrypt it. Encrypted 5x is even worse (I've done both so had a feel for it with and without it)

factory reset and set up as new google account to experiment and see if there is still lag. Just load up a couple of your most used apps to start.
I've run encrypted and unencrypted side by side on 2 5xs on same build with same exact software loaded and there was no noticeable difference within Android. I doubt your lag is because of encryption.
Also if you are running out of memory it just takes a little longer to switch to an app, it doesn't lag all the time. If it is lagging all the time, that is caused by something else.
Any chance you were running low on storage space? 2GB or less free? If so, there's a decent chance that was causing lag as EMMC drives don't perform well when they start getting full.
The way you run decrypted on MTC19V is the same as on previous releases. It hasn't changed.
Use TWRP to install SuperSU then boot into bootloader
fastboot erase user
fastboot format user
If you need root, boot into TWRP and reinstall SuperSU as last two steps will overwrite SuperSU.

Thank you for your post. I think the issue with my phone is that overtime it just became increasingly slower. I always kept at least 6gb of free space as I am aware of the issue of not doing so. Taking off encryption soon after I purchased the phone when it came out did make it more responsive. I now wiped it and loaded 6.0.1 and can say that the phone came back to life. But for how long? This time around I will try to not tweak the hell out of it and to not load too many things through xposed as those were probably the culprits of poor performance over the months.
I will try the commands you recommend to remove encryption, what I did before that failed to work was format the data partition through TWRP. Will my phone remain unencrypted if I side load the next OTA, or will side loading the OTA encrypt it back up? Thanks again!
PS. I am considering OnePlus 3 but the (incredibly timely) review on Anandtech states that the color calibration of the screen is some of the worse out there, and that may just be the deal breaker. It is a shame really as otherwise it is looking like a one fine device.

I tested starting with April release. It is possible with earlier releases encryption was slower, but with April release side-by-side comparison with encrypted vs unencrypted there was no noticeable difference. I loaded reasonably large games, offline GPS maps, web browsing, etc.
Sometimes it is hard to tell if unencrypting is the reason the phone is faster, because as part of unencrypting, you essentially do a factory reset when your user partition gets wiped/reformatted. It is possible your phone could have been faster just by the factory reset with no decryption.

The critical step is *never* boot using a factory boot.img. Then you can remain decrypted.
If you sideload an OTA, immediately boot into bootloader when done, then to recovery. I say boot into bootloader, because sometimes you can mistime the boot into recovery, and boot into android by mistake. I don't remember if sideload immediately reboots when done or gives you some time, but you need to get into bootloader (or TWRP recovery, either directly or via bootloader menu option) prior to initial boot with the stock boot.img, otherwise it will reencrypt.
From TWRP you'll need to flash the SuperSU install zip and that will patch your boot.img to remove foreced encryption. From that point on you are safe.
Honestly, I ran for a month decrypted even though I found no difference in performance between encrypted and unencrypted, just in case there were long term differences. It wasn't until I found a separate issue with my SIM card and visual voicemail that only occurred on decrypted sytems that I switch back.
It's been a few weeks and there have been no noticeable slowdowns for my usage, but I don't have 2 units to run side-by-side right now, so I can't say with as much surety as I could when I literally ran them side-by-side and pressed on the same apps and did the same actions.

apps lost storage access

i have been on DU rom for a long time and i wanted to try 8.0 so in backed everything up and installed the stock oero image. well my experience was not so good but thats an other story, so i flashed stock 7.1.1 again and restored my custom rom via twrp.
everything seemed to work fine but i noticed that i cant take any more camera shots or save images that i get sent via whatsapp or move things around in a file explorer... i tried to google for this issue but i cant find anything on this specific issue.
does anyone have a clue what has happend that the storage cant be modified anymore? and how i can possibly solve this?

If you go back to 7.1.1 stock, you get old vendor, bootloader, radio. So flash Oreo-bootloader and radio: they're working fine on Nougat, too, and vendor, fitting to your ROM.

this can be caused by the vendor version?
i re-flashed stock 7.1.1 again and restored the backup again and now it works again, would still like to know why this happend.

Vendor-misnatch generally disturbs interaction with sensors.
Oreo-radio is simply optimized, better than the old one.

And what exactly has the storage to do with sensors? I dont understand what you are trying to say. And dont see how that would affect the storage access or whatever the issue was.

Sorry. I didn't read your OP right.

march update

Just a quick heads up march up date has been released but the release notes only say that specific fixes are for the pixel 3 and pixel 3 XL. I don't know if there's anything for our OG XL.

I would of thought they would of looked in to the pie battery drain people are having but nevermind I'm still enjoying my experience with the OG XL and I'm still stock. I don't know whether to take the plunge and go custom ?

This is the support map for nexus and pixel phones (expand the sections) and yeah, Pixel probably won't get any new major update.
But, we still would receive security patches until october (theorically)

Well there's really no risk, it's not like something that takes a long time or that you can mess up. You could literally flash any custom ROM for this phone and completely screw everything up to the point where you couldn't use it. Then all you have to do is plug your phone into your computer and flash the latest factory image from Google and everything will be okay. Wiping your phone and flashing a custom rom takes less than 10 minutes and so does flashing the factory image back to the phone if you mess it up. So there's really no downside trying custom firmware on this phone. The only thing that you have to remember is never relock the bootloader. Once it's unlocked never ever ever lock it again. And even that is something that you have to manually do it's not like something you could do by accident.

Don't relock bootloader when unlocked unless you have flashed a 100% factory image but I'm going custom ROM soon just haven't got my laptop back from being repaired.and there should be no side effects if you know what you're doing.

The majority of people who hard brick their devices here are ones that relock their bootloader's and then realize they hadn't wiped and flashed a stock factory image. So they can't use fastboot and end up not having a phone that will boot. There's no reason other than selling the phone you would ever need or want to lock your bootloader after unlocking it. It's just a bad idea all around.

Stock rom issues, BL unlocked no more OTA updates [Help/Advice?]

Hi guys,
I am using the stock rom now since the day I got it and unlocked the BL and installed Magisk for root and SafetyNet. Phone worked fine all the time (lazy me never changed the rom) until recent.
Most applications like Instagram, Snapchat (and all that garbage) and others randomly crash recently.. Application stopped working or process.media whatever stopped. Did try to do the usual stuff removing cache, but now this also does not work anymore. Also it's time to update because the WiFi driver has this RCE flaw(CVE-2017-13292) in it and well, lots of other bugs in the rom. The most irritating bugs that all my android devices had. The flashlight stops working because of the camera initialization or something, need to reboot the phone in order to use the flashlight again (when I was with a hot soldering iron in my car waiting for the device to reboot to solder some ****ing wires under the dashboard pissed me off really good. Though long time ago, but you get the idea... )
I did try to update my device using OTA (I knew it wasn't going to work, because mine is rooted). I did try it and the update failed(lol), luckily the phone still booted :cyclops:
What should I do now, can I just flash a stock rom using twrp or is there another stable rom that is clean like the lenovo roms without all the garbish? Which ones are advised?
The version of the rom I am using as of now is in my signature. I do not really need Magisk anymore for now, I had it installed mostly for NFC emulator but the company I emulated the card for no longer exists so meh.. No need for emulating anymore Pachting ads away with luckypatcher is also not worth it and there's like no proper way of blocking ads so I'll rather live with it instead of messing around and putting effort in it.

Android Pie ROMs are pretty stable and usable now (everything works but be aware that all custom ROMs will have darker video recording in comparison to stock)
ROMs of choice:
On Oreo: RR(Unofficial final builds by fullbustah),CrDroid,Arrow or Xtended
On Pie: CrDroid(has an extended desktop bug), SuperiorOs,ArrowOs,AospExtented
I also recommend installing a modded Gcam version because that will significantly boost your camera quality without any throwback or setback.
To install a pie ROM, I have written a tutorial somewhere in our guides section. You will find it pretty quickly.
Also Magisk 18.1 (latest for now) and Adaway still blocks ads perfectly. (Systemless hosts enabled in Magisk settings needed)
I recommend joining Lenovo P2 telegram group for latest news, support and download links.

Alright thanks for the information. I will try to flash my phone next week. I do have one more question. Is there a hardware selftest or test menu in the stock recovery or bootloader because I have a bad feeling that my board might be about to fail. I think this because all kinds of funky things did happen the last few days (I hope the mainboard is still fine, fingers crossed).. I know my old Lenovo had this menu and this way I found out it was dead. Well it was obviously dead but for sure after the test failed because Android didn't boot anymore, and was not able to flash another rom and get that one to boot up.

I'm not sure if the p2 owns a menu like that.
You might wanna boot to bootloader and navigate through the small menu via volumekeys.
But otherwise...no idea.
Good luck!
