Market Issue

Today I had several reboots on my Desire. After the third I decided to do a hard reset.
Since rebooting the Android Market has been REALLY slow.
It will find apps and let me install them, however the screen doesn't change after the install - it keeps saying installing. The only way to remove the "installing" message is to reboot
I have tried several reboots, reflashed the stock T-Mobile UK ROM and I have formatted the SD card, but none of these have fixed it.
I get the same using WiFi or mobile internet (vodafone UK)
Anyone having the same issue, or got any ideas how to resolve it??
Cheers

Delete please..
See below...

Try THIS!
If not then just wait as the Market on googles servers needs time to catch up with the diffrent build numbers changed, since a flash i belive
Mine took personally after everyflash at least a hour to start even working a bit.
EDIT: Maybe if it carries on being very slow, maybe something happened in the flash whilst in recovery, and has written some data to some bad sectors, causing this issue << only spectulation tho!

Thanks for the link, but I tried that already (after searching for this issue!)
It didn't resolve either issue for me (the slow market, or the installing issue) nor did other threads, hence me starting this one.
Any further help would be appreciated

Lol, i ment delete my post
Then referred to my second post.
Soz for the confusion

Still having this issue.
I have tried the close market place and clear cache/data idea, but no joy
I have now re-formatted (after a factory reset and clearing storage in bootloader) but it still sticks on installing in market even though the app installs fine.
Please help!

Slow for me today as well, stock Desire.
Maybe give it a day?

Okay, its been a few days now and I am still having the never ending install and slow market issue.
Surely I cant be alone??

[Q] primoc cdma kernel crash (all kernels)

RESOLVED
I ran the RUU for my phone, re-ran the update and am stable on 1.08.652.11 710RD
Original post:
I'm getting a consistent kernel crash on all kernels, stock, etc. after the latest HTC update for sprint-vm cdma. Basically, I can get any rom to boot, after about 10-30 seconds, kernel crashes causing the phone to reboot.
I've attached the dmsg log that contains the crash information.
I'm not sure what I can do to fix this issue, as it appears to be a firmware problem. Thoughts?

Try stock kernel if that crashes then custom rom

Stock kernel and all custom roms, ICS and JB have the same exact result. This is why I'm suspicious that this was a bad firmware update. I've read several posts about spontaneous reboots, but most people don't know about dmesg, so I don't have anything to compare to.

Yes, this is the same behaviour. I'm not sure if you're able to dump the dmsg stuff from adb, but certainly same crash. Typically the phone network status shows a little x, right before the reboot. But the lagginess starts happening when the 5 second kernel reboot is issued.
I've tried to change to airplane mode, disable sdcard and everything else I can think of, still crashing and I'm not able to make much of the logging info

When you applied the OTA were you completely back to stock. Like locked bootloader and stock recovery?

Yes, completely back to stock. Unfortunately, I didn't create a backup of the stock image that booted after the OTA update was applied I just restored pre-OTA rom, cwm recovery and boot.img. Everything appeared to be working fine after the update on the stock ROM. However, I didn't leave it on long enough to confirm if the crash issue existed then. Just checked the version info to confirm the update had been applied and rebooted.
UPDATE
I'm going to go through the process again with the RUU and see if I can boot something stable.

Confirmed RUU -> Update worked the second time. This is probably the safest method. This appeared to work initially, but clearly did not. Thanks for all the feedback!

I can't get any non-stock rom to boot after applying the OTA update. Well ok it boots but loops after about 10-15 seconds.
I have to RUU it and not apply the update to get any non-stock rom to work.
CDMA/VMUSA here.

So are you able to run any other roms without reboots? Or are you only on stock?

I applied the OTA update. Only the stock kernel (after update) will boot now. Any non-stock kernel crashes - always seems the last line is rmt_storage, which the IPC to shared memory of the boot loader I believe.

Can you link me to a working RUU?

i got my one v primoc back in the beginning of summer, but then something fell on it and cracked the screen super bad but i loved the phone so much that i bought another at the end of october. i unlocked, wiped, and flashed JB roms... which seemed to work fine for a while & then would have issues of staying stuck in roaming. i've tried different roms. i never had this issue with my first one v... could my new one have the update already when i bought it? i ran the RUU football posted and was able to boot the stock rom... but right away it goes into roaming again, with my phone not even recognizing that it's using a VM service.
real confused...

Yes it's possible that you got one with the update already on it however the problem you are having is completely different than the problem we're describing in this thread and could be caused by many other things - not necessarily the OTA update.
Seems a bit off topic for this thread...

More of the rebooting problem
I have 2 phones one with this problem, the other without it. My friend got one of these phones after i installed jelly bean on mine. He had it long enough to have updated the firmware using the stock image. I made a backup of the stock image, but it seems to have been corrupted (zero byte .zip file). I need to get the phone working (stock or updated, at this point there is no preference so long as it works)
In the bootloader, the radio version of the crashing one is:
1.00.00.0928
The working one is:
1.00.00.0521_2
As far I can tell, this is the only difference. I Used the same SD card and the same procedure for wipe/installing the OS with the same files.
Have you found a solution to this? If so, can you point me to the downloads/instructions for how to fix it?

Looking for help

[Q] Upgrading to B125 from B109

Hi, I just received my P6 and rooted it using eRoot. I have tried upgrading to B125 (running B109 out the box) by downloading the B125 file, passing it to dload on SD and performing a local upgrade, once the device boots to perform this it immediately says FAIL, and if i select the file manually it says "E:\signature verification failed" any ideas on how to solve this? Am I meant to update to something else inbetween before jumping to B125? (I've downloaded the file twice just to make sure it isn't corrupted or anything). I am a complete noob with this device, used to doing this sort of thing through CWM on my Nexus 7.
I have looked around this forum and seen various answers involving using TWRP first which if I could avoid I'd like to avoid as my aim is to load stock firmware without any of the bloatware that comes with my service provider, I'll leave the CFW stuff like AOSP for my tablet.
Any help would be greatly appreciated!

Try to do a MD5 sum check. Probably your download or copying to SD card is corrupted.
Redownload the B125, but worse comes worse, try B118 or B122.

Re-downloaded it and used a proper zip program to unzip the file and it worked!!! So happy
Quick question what would you guys recommend I do to get rid of the service provider bloatware that came with my phone because with the upgrade all that stuff still stayed on my device? I tried uninstalling it normally and it just says system application cannot uninstall...
Battery life is a HUGE improvement. Sitting on 40% after 15 hours of abuse. Thanks again guys!

Latest T-Mobile Update Slowed Down My Phone

Hi guys,
So i just downloaded and installed the latest T-mobile update and now my phone is slower.
Every time I hit the home button, the image blinks and redraws and there's just a hint of stutter.
The app drawer also takes a little longer now.
What the heck?
It used to be so zippy and fast. How do I fix it, anyone know?

Try disabling hw overlays in developers options to help with that redraw stutter. Remember you have to set it everytime you boot, unless you're booted with xposed installed, then you could download the module that keeps it active at all times.
This seems to have helped a lot of people with your issue.

Thank you.
It's sadly still doing it.

Did you take the ota or download one of the twrp upgrades floating around? Either way in your situation you probably need to do a factory reset. Alternatively follow the twrp method HERE if you haven't already and I can personally guarantee a better than ota install. If you want it to be done correctly to fix any problems you need to wipe the system and data partitions before flashing. Also don't forget to download super su if you want to keep root (linked in guide). There is another upgrade twrp file in the development section I think that is not a perfect 1:1 image and could give problems. Not saying that particular rom is bad or that it is the problem, its just not a 1:1 like the guide I linked you to it is directory/installer script dependent. The one I made transfers the whole untouched partition over and inside has all the symlinks and permissions preset by LG.

Factory Reset

OP3 phone is un-usable please help!

Hi everyone,
I have an issue with my wife's OP3 that is driving me nuts.
Her phone runs stock OS without any changes but with an unlocked bootloader (just to be on the safe side i like to have an unlocked bootloader on all our devices).
I'm not sure if its related but I'm including it anyways she was playing a game on her phone and then she received a call and she answered it and tried to switch the call to speakerphone and the phone started rebooting right after booting the OS after 2-5 sec i would say "factory data reset" (see attached screenshot) and would reboot to the recovery.
then i would boot the phone again and the issue repeats itself.
so i used fastboot boot twrp.img to boot a recovery image and run a nadroid backup to a USB OTG just in case the phone is really hosed or whatnot.
I downloaded stock zip from oneplus's site and flashed it again from TWRP just to make sure its not some funky issue that happened to the os.
I even factory reset the phone from stock recovery and the issue would happen on the new phone setup wizard.
after a bunch of fiddling around I've flashed LineageOS 16 nightly and the phone boots normally and is fully usable but when i try to make or receive a call the phone app freezes and then crashes also sound doesn't seem to work when i try to play videos from youtube for example.
Any ideas what is the issue and how i can resolve it ?
thanks a bunch !!

Take a backup of your personal files and then wipe system, data, internal storage and both caches. Then flash OOS 5.0.8 and without adding any apps, check the calling function. If it still happens, then most likely a hardware issue.

No, She did not do anything out of the ordinary. But weirdly I have exactly the same things happening. Lineage works but no sound. Everything else factory resets. I have tried quite a few ROM'swithout any luck. So far the only ROM which worked for some time(1day) was 6.0.1 . I have spent quite a long time on this flashing various ROM and dont know what to do now.

Update: @ireaper4592 might have a point here. I have gone one level up and I tried msm v3.0 tool, thus doing a complete reinstall including firmware. The factory resetting stopped but the sound was not working (I thought that it could be the ROM and the security patches). So I updated to the latest ROM available from Oneplus and evrything has been working since. I did this last night so not sure how long this is going to stay like that. I will give it some time and update later. Wife is using it now!

what you will need to do is download the oneplus 3 recovery tool and put the phone into qualcolm mode and restore the phone that way. here is a link https://www.androidexplained.com/oneplus-3-unbrick-return-stock/

That tool/procedure will reset your phone. So you will lose everything on the phone. Take a backup beforehand.
