Lenovo Yoga Tablet 2 830F - Android 5.0.1 - Lollipop ota update 2 from Lenovo (20/7/15)
Filename: YT2-830F_USR_S000195_1504220230_WW21_ROW_TO_YT2-830F_USR_S100067_1507101258_WW52_ROW.zip

INFO !!!
My first update OverTheAir with this file was a fail. Only black screen after update and reboot.
(I think because i did not change the country code after flashing KitKat a few weeks ago)
(If the update stuck at 100% in recovery you also have to reflash KitKat ROM)
So i flashed original 830F KitKat ROM via "PhoneFlashTool" with this ROM / Tutorial:

http://www.android-hilfe.de/thema/tutorial-wie-installiere-ich-das-kommende-update-wenn-es-nicht-funktioniert-fuer-alle-varianten.697884/
Changed the "Country Code Setting" via ContactApp ####6020# to "de" (select your language).
And do not update any app like Chrome etc. when it reboots again after.
Then download and start the Lollipop 5.0.1 Update.
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS... :cyclops:
INFO 2 !!! (if you installed Lollipop update 1 first and now restoring/flashing of KitKat ROM fails)

I have the same problem, only that I had the first Lollipop version for 1050F with root and then got the new Lollipop update. The Kitkat version fails to flash. But here is what helped: Go to this post http://forum.xda-developers.com/thi...-8-10-13-3-t2930428/post60490907#post60490907
and download the LtoKKxml.7z and copy the files into the kitkat firmware folder and then flash using flash-LtoKK-PVT-810.xml
I had to remove the parts of the XML that erase and format data. Then it worked
After that I could flash KitKat!!

LOLLIPOP ROOT
So easy, follow steps 1-8: http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096
I download "IntelAndroid-FBRL-05-16-2015-PTR.7z" and "UPDATE-SuperSU-v2.46.zip" and it worked with Lollipop 5.0.1.
Make sure you have all the Android, Intel, ADB driver stuff installed (for me win7 installed another one at rooting?)
!!! USE OPTION T4 FOR LOLLIPOP ROOT !!!

Yup I got the notice a few mins ago. I also got it many weeks ago when it bricked my yoga 2 8.3
Advice, when it says Updating....100%. Leave it alone. Last time I thought it was done since it said 100% for many many minutes. So i thought it was stuck or bricked. Just let it sit. It will reboot by itself and restart to the next phase.
It will also sit on the Lenovo android screen for quite a while before it goes to Android is upgrading.
Yes, i got problems too!
- It stays for 8min. at 100%. I leave it alone...
- Then 4 chinese Buttons showed up.
- I pressed the first (reboot i think)
- it reboots, it shows the white lenovo text, then black screen with background light on.
- i waited 10min., no change or start into OS.
- then i pressed 15sek power off, light goes off.
- if i power on, again white lenovo text, then black screen with background light on. nothing... ???
i reboot into recovery and wiped cache, nothing.
i think i will make update from SD card again... see if something happend
Update again from SD dont work! it says:
"/system/app/Chrome.apk" has unexpected contents...
E: Error in /sideload/package.zip
SUCCESS, LOLLIPOP IS WORKING!!!
I Have restored original KitKat ROM via "PhoneFlashTool" with this ROMs / Tutorial:

http://www.android-hilfe.de/thema/t...icht-funktioniert-fuer-alle-varianten.697884/
This time i´ve made the "Country Setting" via ContactApp ####6020# to "DE" befor download and upgrade!
And i have aborted the automatic PlayStore updates for Chrome etc...
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS...
So can you boot back into android? Even after you wiped it? If not and you can't do anything, call Lenovo. I think only they can fix it.
If you can get back into android, I would suggest waiting for the System update notice. That's what showed up this morning for me. I didn't have any chinese buttons. I didn't have to touch anything, just wait for a really long time which is unnerving because I don't know status.
I flashed the KitKat Version again, changed country code, and installed the new Lollipop 5.0.1 update again.
This time there are no chinese buttons to press. (i think because changing the country code befor update).
Lollipop is great, the display is much faster while scrolling in chrome etc.
Interesting. I wonder what the difference between the versions of the country codes are. Mine bricked last time it was updated to lollipop. When I got the repair back, it was back to kitkat and I couldn't update until this morning.
Glad to hear you got it fixed. A few of my apps also stopped working and I had to clear the cache to get it working again after the update.
There are some differences in pre-installed apps. I did not changed the country code few weeks ago because there are some apps in german setup i do not want...

You need to flash the stock kk firmware.

From my LG-G3 running Jasmine8.0/Skydragon Kernel 4.2
Yes, It looks like I cannot just upgrade from rooted KK. I had to go back to stock kk firmware provided in the OP's link and follow step by step instructions using google translate. thanks workdowg and 5m00v3.
anyone missing 5GHz band Wi-Fi support with country code DE? I cannot seem to change the country code once it has been upgraded to Lollipop.

Lollipop does not longer provide the option to manual change band... it will auto connect to 5ghz if possible.
It has nothing to do with country code DE. You can check your connection 2,4/5ghz with the app "wifi band".
My YT2 connects automatic to my 5ghz. And i have 2 networks (2,4 + 5ghz) with same networkname.

Okay, I found the solution ! Make the tablet totaly Off, press volume up and volume down, than press power bouton, you directly acces to fastboot mode, and here you can flash with Phone Flash Tool.
Hi,
thanks for the timming TIPs !!
I can't believe LENOVO dosen't take care of this basic things !!
Thanks to you Lollipop is running on my beloved Yoga.
A little tip while we are avaiting 5.1,
Go in Parameter
Activate DEV options : About this tablet, touch 7 times on "Build Version", it will activate the Developper Menu in parameters
Go to Developpers Option (in PArameter)
UNCheck NuPlayer in multimedia.
--> REBOOT your device
It will allow you to avoid Lagging into the UI and apps.
Note that in 5.1 NuPlayer has been replaced by a bugfree version.

Googling ”E: failed to verify whole-file signature" and each one talks about a corrupt download... They are old posts from 2013 or so but they could be right.
Try this version 2.40. You can update in the Play store once your rooted.

Thanks for your help.
I tried the 2.40 version triple check the zip file, aleas same error...
Also there are not only corruptions problems related... some are related to CMW version problem and lack of "unsign" option..
Again thanks for the 2.40 link. If you have any suggestion I'm all ears.
There is a new update, to yt2-830f_usr_s100191_1511230623_ww52_row
anyone tried it already?
Looks like it requires going back to stock KitKat again just to update it.
Can't really be bothered trying it.
ASUS ZENFONE LASER 2 (ZE550KL)
So, I rooted and installed lineage OS, it worked quite well for a month or so, then :
1.) First of all, there was no network detected for both of my sim cards.
2.) On restarting the phone, it stuck in bootloop for 10-15 mins and then started, this time showing no sim card inserted, there was null IMEI when I check it in settings.
Went to twrp, wiped everything except sdcard and usb-otg, installed lineage, everything worked fine. Now, after some days, again the above 2 things happened.
Removed lineage and flashed Resurrection Remix 7.1.2 for the phone. Worked fine for 2 days and again network gone and no sim card with no imei. So, now i know its not a ROM issue.
Every ROM works fine and then randomly deletes IMEI after some time. Can someone suggest anything?
EDIT : I used this guide https://forum.xda-developers.com/ze...50kl-ze551kl-zd551kl-ze600kl-ze601kl-t3333482 . Now I have a stock recovery with no OS installed. Flashed the stock downloaded from ASUS website via "Apply update via MicroSD". Phone stuck in bootloop, sometimes starts showing "Optimizing App 1 of 1", then restarts all over.
Now, I have a phone with stock recovery and which won't start. Desperate for suggestions, anyone help please.
Hello everybody hope you having a better day than main, i tried to manually-by my self to update my phone to emui 8 but since I'm a new to Huawei unfortunately i couldn't reach my goals and my phone was boot-looping so I've tried my best to revive my phone by flashing a costume ROM for Huawei Mate 9.. Now i don't have the (4G+) sign which is mean "i think" i lost the CAT6 on my phone and back to CAT4, i can not use the multi task screen, I think that's what it's called!? And so many other standard yet important options.. anyhow I've tried about a month ago to superSU my phone but it's failed and I end up by frieing the motherboard and the warranty took me 14 days to fix it and i don't want to repeat that experience again...
So if any one have a flash-able zip or .img or a TWRP back up files for the original firmware he\she will be my next idol
Hello, I am new here.
Actually, some months ago, I was trying to root my realme 2 pro device and ended up messing my recovery partition and stuck on a bootloop. As it was covered in warranty, I sent my phone to repair (not official). They fixed my phone for free and said that they changed the motherboard (dont know why they did that), and can confirm because serial number is changed, and it has been working fine since then. But when I got news that RealmeUI was being rolled out to Realme 2 Pro, I noticed that I couldn't update because on the update screen, it is showing, already on the latest version RMX1801EX_11_A.11. So, I tried to manually download the firmware and tried to flash but got error that the update is not supported (I'm sure I downloaded the correct one from realme website). Also, I cannot unlock my bootloader as the In-depth test app is showing "The current app does not support your system, please update your system version". Kindly guide me what should I do, have the repair guys messed up something? Any help would be appreciated.
Hey all,
DIdn't find any info, or perhaps I'm already lost?
Just did a reset to my device, it is running an old 5.0.2 firmware.
Trying to update it to a better version.
In asus website, I manually downloaded a marshmallow 6.0 firmware, dropped in the root of the internal card but the system doesn't even recognize this update.
Firmware zip file: UL-P021-WW-4.6.5.0-user
So... Any way to manually run the file? externally?
p.s Tried to get into the bootloader but only got a "fast boot" screen with no option, but "click 10 sec to turn the device off".
** unless anyone already solve this and have a better rom/version - would be happy to hear about it too **
Please advise on this.
