[Lenovo A850] René Droidz:
I have a bricked Lenovo A850 with a faulty USB connector, while it can charge it cannot connect to the computer. It goes into a bootloop and all I can access is the Android System Recovery 3e. Without a custom recovery installed and without the possibility to connect this phone via SP Flash Tool/ADB I feel clueless about what should I attempt. I ordered a replacement part, a dock charging board which I believe could bring back this phone to life. It is not a driver issue, I do not reach the point where I can see something in Device Manager or USBDeview. All I see in USBDeview is "Unknown USB Device (Device Descriptor Request Failed). Meanwhile can anyone provide me some hints about what is possible to do.

Since the Android System Recovery can only load a update.zip file I have no idea if is possible to flash a stock ROM from the Android System Recovery. Without CWM/TWRP I feel totally lost. I tried to install some image file for CWM/TWRP, by renaming them to update.zip but I did not work. I got the impression that a stock phone does want us to push a custom recovery and flash a ROM. The fact that the Android System Recovery starts gives me some hope that it is not a hard brick yet.
[Lenovo A850] irfanadli97:
I can only assume four things:

1. Your phone had OTA and you installed it, therefore ANY kind of flashing will not work before you flash stock.

2. You have the generic chinese (non-ROW) unit, therefore there is 2% success rate of flashing anything with the generic tools, not the specific tools made by Chinese devs.

3. In the USB department, your work does not end there, as there is few more steps you have to do, GreatApo made a post about that.

4. As I said, SPFlashtool is the wrong tool. Use the tool made specifically for MTK phones like the MTKDroidtools.

And FYI, this particular model (some units) does not support flashing via ADB commands, as those libs are removed by SOME manufacturer, well they want you to STICK WITH THEIR FLASHY STOCK ROM WHICH ISN'T PRACTICAL.
[Lenovo A850] irfanadli97:
Human breathren, I see that thee art having a problem with thy phone, and I knoweth jump what thee hath felt. As such, alloweth me pray pardon me to thee what actually is going on.

Lenovo is technically a Chinese company, but the good one. They make great smartphones at such a price you can say "YEP, TOTALLY WORTH IT, 1080P SCREEN AT $100!", and that's a success Lenovo made. Because of that, unauthorized shippers ( and recently manufacturers) taking this advantage and gain money by "sideloading" units of their phones, that is SUPPOSEDLY for the country China only, to shippers who chooses to pay minimum shipping taxes, to WORLDWIDE.

Thus you may see Lenovo smartphones at 20% cheaper than original retail price plus taxes. These discounted phones are TOTALLY Chinese models that contain bloatwares that somewhat nonsense and useless.:silly::silly:

Chinese ROMs that come with it is really paced to straightforward users, that are not planning to customize their phone at framework level. So all bloatwares you see now is actually making sense for them, only, not for us power users.

First problem that I see now is your USB port. Well it's all about construction of the USB port opening (the plastic inner housing). The thing is, there is a significant little gap between the metal port and the housing, so for a long period of time, the metal housing bends thus damages the port until it becomes unusable. I lived with this, experienced this....it's so painful I know. See pic.

[IMG="I highlighted it for ya."]http://s2.postimg.org/ry6wlep7t/lenoport.png[/IMG]

Second problem I see is storage problems. This particular phone has TWO partitions of system storage, namely internal and USB storage, totals up your 4GB you are getting. The one that ALWAYS getting full is your internal or C drive or '/sdcard0' (That's why if you want to move apps to SD card, the option is 'Move to USB storage') . Only Chinese ROMs have these because the second partition can emulate the functionality of a real SD card, and the point you ask? Well, easy for them to bulk flash their modified Chinese ROMs, with their special type of recovery and kernel which TILL NOW I cannot understand HOW it works.

What is left is 300MB+ of space for your apps, appdata and appcache. Bummer right?

So my workaround is, getting root, remove most of the bloatwares via Uninstaller[Thats the app icon colour]. And also (in planning, because I do not want to take risks before I confirm it'll work), moving entire /data from /system to /sdcard1.

SO THERE YOU HAVE IT.:victory:

huuhh.....

Source code for this phone just recently released. So I waiting a CM for this phone.:laugh::laugh:
[Lenovo A850] René Droidz:
Updates and problem solved!

UPDATES :D

After successfully replacing my charging board for 4$, I was finally able to flash a stock ROM and bring this phone back to life. Unfortunately, it wasn't smooth as I expected. I was challenged by two more issues:

1) MT65xx Preloader Problems: Dispite been able to update the driver to the right version "MediTek PreLoader USB VCOM Port" could not stay connected more than five seconds. I could clearly see in USBView that I could get a green connection but there was no obvious way that I could maintain it. Feeling hopeless, I started SP Flash Tool v3 1316, loaded the scatter file from a stock ROM and launched the download process knowing that nothing would happen since SP Flash Tool would be searching endlessly for a connection. Then I unplug/replug my phone, by some kind of magic the download process started and finished without a glitch! First boot went well and this phone was back in business. It seems that the USB connection could not stand being idle in Pre Loading, that some kind of command must be issue to keep the connection alive. After the first boot from a fresh Android, my computer correctly recognized my device as "Lenovo A850" without any issue. :)

2) Invalid IMEI. For some reasons I could not use my two SIM cards as previously since IMEI of both SIM slot were not identified by my new OS. I had to do some engineering tricks by using "Engineer Mode MTK Shortcut" and tutorial on Youtube. Lucky enough, my sticker inside my phone was still intact and could set those IMEI digits back on this phone. Everything seems to be functional now. :D

Will I buy a Lenovo phone again in my life? No! :crying: While the process of restoring this phone was interesting, the amount of time I spent on this phone was not worth it. My time is worth more than hours of trials and errors and having to deal with "Chinese customization" was not by cup of tea. I will get my girlfriend an Asus Zenfone 2 once this Lenovo gives up again.
[Lenovo A850] irfanadli97:
*cries with you*:crying:

Just..give up man. Lenovo A850 is an architectural failure for me. Just wait for K3 Note for the CM to be released. Mine's dead already because of the USB failure and I gave up.
[One (M8) Q&A, Help & Troubleshooting] uggitt:
Hi,

My phone got the red triangle and exclamation mark after upgrading my firmware. I believe this was due to it wiping the custom recovery which was TWRP. I have tried to reinstall TWERP but I get stuck on the entering recovery screen.

I have tried to install twrp a couple of times with no joy but I have a copy of philz recovery and this installed 1st time.

Any ideas? I have tried clearing the cache in fastboot but am stuck.

I have no phone as the rom I install is on the ext sd card and Philz touch will not mount the ext sd card.

Thanks in advance

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
You reverted to stock recovery, which flashing firmware will always do,

unless

its a modded firmware which has the stock recovery removed.

Confirm that your bootloader is UNLOCKED (which is

needs

to be to flash recovery).

Also, if you update to Lollipop firmware (which is usually the reason for updating firmware) you need to use one of the more recent TWRP versions. I recommend TWRP 2.8.7.

Older TWRP versions do not work on LP, and fail to install properly is the mode of failure. Similarly, Philz does not work on LP.

EDIT: To clarify TWRP build.
[One (M8) Q&A, Help & Troubleshooting] uggitt:
I have checked and the bootloader is unlocked, s-off and super cid.

The problem is I cannot get twrp to load up. I install it with fasboot and all goes well but when I try to get into recovery it just stays on the entering recovery screen.

I have tried to reinstall the latest firmare using the'Firmware Flashing without the panic attacks' guide as I have always used and this seems to install ok and then tried to install twrp again ( I have tried the latest and the previous copy) but no joy. I can though install philz recovery and that boots up fine.

So still stuck trying to get twrp installed.

Also if I reboot the phone hangs while starting upon the htc screen with red text but the phone is actually working behind this, just cant see the normal desktop/startup screen. If i hold the power button so the screen goes off and the hold the power button to turn it on the screen comes to life.

For information, I am on Android HD 41.0 as this is the only rom I had on the internal sd

I beg to differ, no problems running 2.8.5.0 or 2.8.6.0 on lollipop for me. Installed via fastboot or flashify.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Your firmware flash never properly "stuck".

Your getvar data indicates you are on the original version firmware (1.54) which is over a year old. The current firmware would have updated you to hboot 3.19, radio 1.2xxx, and main version 4.16.401.

This also explains why Philz works, and the current versions of TWRP do

not

work. The current TWRP versions only work on Lollipop firmware; and only older TWRP versions work with your 3.16 firmware.

Try running the 4.16.401 firmware twice, this is often necessary to get it to flash properly. Then once you've confirmed you are on hboot 4.16, radio 1.2xxx, main version 4.16.401, then try TWRP 2.8.7.

---------- Post added at 03:19 PM ---------- Previous post was at 03:14 PM ----------

True, a few of the recent builds will work on LP. But older ones than that won't work, trust me. I forget the breakoff point exactly, which is why I recommended the most current version (2.8.7). And once the most current version is known to be stablen (which 2.8.7 is), its usually the best recommendation.

I didn't mean to state that 2.8.7 is the

only

version that works. But I see how it can be interpreted that way (and have edited the previous post for clarity). For some reason, I constantly see folks still trying to flash much older TWRP builds (2.7 or so) onto Lollipop (which won't work).

And it turns out the OP had the opposite issue (trying to flash newer version TWRP on really old firmware hboot 3.16).
[One (M8) Q&A, Help & Troubleshooting] uggitt:
Thank you, I will try and flash the firmware again. Have you a link for this. I have been getting it from the ARHD Firmware page but not sure if its corrupt.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
4.15.401 (Euro) firmware is probably

the

most commonly downloaded and installed firmware from that collection. So it should be fine.

You probably just flashed the firmware once; when twice is often needed.
[One (M8) Q&A, Help & Troubleshooting] uggitt:
I managed to get the updated firmware on my phone eventually. I had to download from another link and it flashed first time.

Twrp installed straightaway and I am back on S.Rom.

Thank you for all your help, much appreciated

Hi

under settings -> data usage i enabled "limit backgroud data" for google play service

today i found that my address book it was not syncing with gmail, so i try to do it manually but it just gave me a RED ! saying that an issue occurred

i tryed on 2 different google account several times and it did non sync

when i connect the phone to my wifi network it synced without issue

i'mont sure if limiting background data for google play service is the problem but i don't know how to remove that settings

under data usage i can't see it any more
[Galaxy S6 Q&A, Help & Troubleshooting] XxM4tzexX:
You are most probably right. Limiting Google Pay Services can affect everything. Syncing with your Google account and push notifications are two functions which are affected by Play Services. So you have to find a way to remove the Limitation. But normally Play Services should be listet.

[P3300, MDA Compact III General] strongp:
It's running painfully slowly and the GPS won't work so I'm going to hard reset my XDA and get rid of the O2 crap, then install TomTom. I know all this stuff is here somewhere but I’m up to my eyeballs in tech articles so…. Questions:

1. Should I upgrade the ROM, and if so can anybody point me to a suitable ROM image? If I do this should I unlock it first?

2. What's the best way of getting a clean install - is it to hard reset then soft reset before the O2 stuff loads? Or should I go for a cosporate install option (is this available for the Orbit) And how do I hard reset?

3. is there an easy way of setting up the O2 connection settings afterwards or do I have to do it manually?

Lots of questions and not enough time…. :(
[LG G Watch R] nai1sirk:
I've go several problems with the watch, but thought I'd start with this:

If I try to restart my watch, it stalls at the LG logo. It has to be docked in the charger to be able to boot. It does not matter if it has 90 % battery left, just will not boot. I could have lived with this, if it at least would keep a stable connection to my phone, right now it's pretty useless:-p

Should I just RMA it?

[G4 Q&A, Help & Troubleshooting] egandt:
On my note 3 this works fine for me, on the G4 Anyconnect ICS+does not allow me to click OK (only cancel), so while I should be able to use the app (password is accepted ...), I'm unable to access the office, which makes the phone far less useful. Anyone know of anything special required on the G4 to allow VPN connections; it is as if the Android (which is responsible for the prompt as I understand it), is blocking the OK button. This all worked fine on my previous phone, so I'm assuming it is a G4 issue, maybe some setting I'm unaware of?

Thanks,

I'm still getting such bad battery life that if this firmware doesn't make it better I'm going to TMO and having them buy out my edge program. So COME ON FIRMWARE. I'm not optimistic.
[Verizon HTC One (M9)] GuestX0011:
Here is the think. Are you speaking of Firmware. FirmWare of Which has to go to Computer engineers and not the swash of Software Engineers that exist and work for every company?

Here is the thing And It seems that you and MANY MANY people do not understand Hardware.

They are still trying to optimize the code that RUNS the hardware. The screen is done already no power improvement can be done there as it is manufactured. Kernel level code that controls when its on etc yes can be modified. Updating the Firmware is no guarantee that it will make power consumption better. Optimizing the Kernel and how the CPU is used and when to shut things off will help. BUT there is a limit to where they have made it as efficient as possible. Can you come up with some solution that allows the Radios to communicate better that is certified with current technology. OF Course but it may only relate to when its on(HOW MUCH POWER IT USES-You want good signal right?).

The thing is the unit is hungry by default. A Simple Firmware Upgrade just isn't going to fix battery drain UNLESS

and I SAY UNLESS

there is a major bug that keeps a unit*component on the board* running, or IE using max power for the radio due to a signal strength glitch, or something that keeps the CPU on all the time instead of sleeping..... Things like these are fixable in an update.

If they can find power draining bugs/glitches then yes a firmware upgrade would help

Other wise IT is rare that they can just optimize over and over and over again. There are only so many fixable power draining issues that are caused by code that an be fixed.

This is something That I have learned while working on my BS of CE. Now Industry techs who pioneered this tech would be able to give a better answer

Also they have to make CPU profiles that fit everyones needs. When people install Power saving Profiles they get better battery life at risk of CPU strength. This is just nature and a way that modern can personalize their devices.

Also Android is still a battery hog :/ and the fact plenty of places have crappy signal suck to.
[Verizon HTC One (M9)] Dstu10:
I have not experienced any type of battery drain on the phone. However the M9 seems to suck battery when running apps that require the screen to be on, or use a lot of resources to run. I do not see this as a problem with the phone, it is a problem with battery technology not keeping up with phone technology. Or to even elaborate more, there are much better and longer lasting batteries that could be used in phones, we just wont accept paying $2,000 for that technology. If you think this phone is bad you should try out the s6. You can drain the s6 battery in about 25 min with the screen on if you are lucky. I guess that is the cost of a better screen.
[Verizon HTC One (M9)] rsa 329:
I disagree. I would bet it's this horrible os called lollipoop. Or the crappy kernel. But its debatable, I think the battery technology is actually pretty good.
[Verizon HTC One (M9)] Dstu10:

[Verizon HTC One (M9)] rafaelloaa:
(As a bit of background, I'm pretty good with computers in general, but I have 0 experience with rooting/dealing with the inner workings of Android). My phone is stock, the only major change I've ever made to it was to install Nova Launcher.

Sorry to necro the thread, but the last few months have been crazy busy for me, and I am realizing that I don't see any changes to my phone. I got the 5.1 update when it hit, and didn't think much of it. But my swipe-down menu looks exactly the same as it did in 5.0, I (still) can't use the power saver mode, I can't get the feature that prevents the phone from being wiped if stolen, etc. None of the changes mentioned on various websites seem to have taken effect. But the version says I'm running 5.1. Any ideas?

Apologies if this isn't the right place to post.

Many thanks!
[Verizon HTC One (M9)] Threefifty:
To the best of my knowledge, Verizon's actual stock will not have the power saver feature. The deodexxed modified stock ROM by Andybones has that included, but to install that you need to be rooted, to be rooted you need to get your phone unlocked via Java card.
[Verizon HTC One (M9)] hgoldner:
This. Confirming (as a tester for HTC) that for some reason Verizon doesn't like Powersaver and requires HTC to remove it from their ROMs. Test devices I have used on other carriers almost always have it. I cannot begin to fathom what Verizon's motivation is, but if I understood how cell carriers "think" I'd likely be a wealthier man.
[Verizon HTC One (M9)] rafaelloaa:
Thanks for the info. Shame VZW pulls this ****. Like how they disabled the FM radio chip, ya'know, because.

So just to clarify, my quick settings looks like this: http://i.imgur.com/r3uDAX4.jpg, whereas all the info about the 5.1 update show the settings looking more like this: http://i.imgur.com/lsRhJpW.jpg. Is that just different models of phones, or did mine get messed up somehow? Because I honestly can't see any of the differences listed for 5.1.

Many thanks!
