Manual update to Marshmallow without rooting? - Xperia Z2 Q&A, Help & Troubleshooting

Hey awesome people!
My first post here. I got a notification of an update a few days back and tried to update my phone (never even touched in matter of rooting etc.) to the 6. But with OTA, I keep getting the error "Pending Wi-fi Network" before it finally fails. I tried at a couple places around town but no success. I finally tried via Sony PC Companion but even that doesn't work. After switching off my mobile and proceeding to download the firmware, PC companion fails time after time before finally showing an error screen that says there's a problem with internet, which there is not. I've got a 10mbps optical fibre net for Nokia 1100's (god's) sake.
So I ask you, oh humble masters of devices, is there any way to flash the official Marshmallow to my Z2 without unlocking the bootloader or rooting it?
Thanks!

Hi, you can, use flashtool (google on xda xperia flashtool). also many manuals online which will help you through the process. good luck and enjoy (since last week I upgraded from 5.1.1 towards 6.0.1, very happy with it).

Oh! Yep.. Found the button!
Thanks!
Also, will my data be erased? I'll have TONS of back-up to do in that case!

If you don't select wipes in flashtool your data should survive, but please DO make backups before trying to update, something might fail, your computer may crash during the update for example and you could lose all your data...
I ALWAYS make backups of my data before attempting rom updates / reflashes. Better be safe than lose all your precious data

Need help with updating rooted neo

Hi guys, it has been awhile since i rooted my neo, with a guide I believe I found here.
I'm currently on version 2.3.4 with root and would like to update to ICS or higher if possible.
Now I've tried to do an OTA update but it restarted my phone with the announcement that it couldn't upgrade to version 4.0.2.A.0.62 (luckily not bricked)
So now I have a few questions regarding this. I have the superuser app on my neo(MT15i) and i found 2 options which may or may not work. These are "temp unroot" and "ota survival". I haven't used these options, afraid of bricking my phone.
All in all, anyone know the correct way of updating my phone?
thank you for your time, reading this
Ether update your phone with PC Companion or Sony update service, and root it after.
Or you can flash one of the ftf's with flashtool and root it after. These you can find in sticky thread in general section.

Thank you for your reply. I already tried via the PC companion and after an hour or so, it still didn't do anything.
As for the other solution, I will try this as soon as possible. If I understand it correctly, if I update my phone succesfully, I automatically lose root? And afterwards I should root it again?

Yes. Clean install wipes your phone. So make backup.
Only in some cases when it's small update(ie. not changing android version) PCC or SEUS leave data partition intact. But in that case you can click repair option in PCC or flash it with SEUS(SUS) and your data will be wiped. Which is what I suggest as it's always good to have clean phone when you get different android version.

No error at all, it seemed to be stuck at preparing the phone for the update, furtheron there was no sign it was actually doing anything in the background.
And i made a backup of everything on my phone with the app backup master. Or do you suggest another/better application?
http://forum.xda-developers.com/showpost.php?p=24983903&postcount=2
I found this post by you, I could use the same procedure to update my phone right?
small edit: both your dropbox link and 4shared link are down
Use whichever app you want, if it backuped what you wanted then it's ok. I personally use MyPhoneExplorer as I only need sms,contacts and notes/tasks(from calendar). Don't know how MPE goes with apps, you can use titanium backup for apps.
That is old tutorial with links to old android 4.0.3( build .562), but it still works(4shared is not down, as I tested it now).
That's why I wrote, in above reply, to check sticky thread in general section. So no need to look around.
p.s. read a note in that (sticky) thread, make backup of your CDF customization number. OR simply update it with PCC(I guess you caught it on a bad day, usually it works ok) or SUS.

[Q] Xperia Ray won't read SIM after brick rescue..

Any ideas on how to fix my Xperia Ray? HELP..
Quick backstory - my Xperia Ray won't read my SIM card anymore. It doesn't even ask for my PIN number, it just boots as normal (after asking me to pick a language) but I have no connection to any network. I've tried using the SIM card in another phone and it works fine, therefore the problem is with the phone itself.
I'd recently had my phone network & bootloader unlocked by wotanserver using the test point method - because of this I thought the DRM keys would be fine (e.g. TrackId & Timescape still worked). However, when I was updating from GB .42 to .62 OTA (to flash a GB ROM) my phone bricked! (Does this mean the DRM keys weren't intact? Confused.)
So, I searched for a solution and ended up using s1tool to relock the bootloader. Then I used flashtool to flash a stock ICS ftf file. It seemed to work (the phone rebooted) but it was then I noticed that the SIM card wasn't being recognised. Also, in the Flashtool log I noticed that a blue line was there saying 'this file is ignored simlock.ta'.
Anyway, my real dilemma is - which of the Available Omnius Operations for the Xperia Ray (see link: http://www.omnius-server.com/phone?id=20… should I pick to fix this?
Backup TA
Flash
Identify
Live boot
Repair S1-boot
Restore TA
Revive phone after OTA flash
Unlock bootloader
Unlock network lock by certificate replacement
Repair S1boot? Restore TA? I really don't know. Would really. really appreciate someone's help - I need my phone back urgently!
Updating via OTA on an unlocked bootloader does lead to a bricked Phone, which just requires THIS to fix it.

Hi, thanks for your reply! I'm not sure what you mean though - the link provided in the first post on that thread took me to a dodgy website to download a file called 'downloadmanager
_setup' All that did was install crap like 'Zoomdownloader' and other non-android related rubbish on my computer. So I'm not best pleased about that...
Anyhoo, my phone isn't really bricked - it works fine apart from the SIM problem. I was asking what fix in the Omnius list of options applied to my situation. Do I need to Repair S1-boot? Do I need to 'Restore TA?' I really don't know to be honest.
All I really need to know is what option from Omnius's list applies to my situation...

Just checked the link myself, as it didn't skip the ad and asked you to download something else instead, that should have rang alarm bells. This is what you should have downloaded - FlashTool_0.2.9.1_FOTAUnbrick

Your Phone was bricked in the first place due to an OTA update, and should actually state in what ever thread you used to unlock not to use the OTA feature after doing so, the attachment normally fixes that, given that you've re-locked using S1Tool then you may have done more harm than good. If I knew what option to suggest I would have done so, so unless anyone else does then it's trial and error I'm afraid.
Is it too late for me to give the link you gave me a shot then? Or might it do more harm than good at this stage? Thanks for your help btw, I appreciate it.

You could try to unlock the boot loader again, flash stock ICS and kernel and try again to connect the sim card...
Or have you tried PC companion to fix your phone? Try this first!
But I can't promise anything, maybe you will end up in a bigger problem than now

COMPLETE guide to BRICK your Truesmart! --{SOLVED!! Unbricked!!}

[update 2] I just summarized a way to backup and restore (all based on other great DEV's work, just put in one place) your TS before your play with your TS here: http://forum.xda-developers.com/showthread.php?p=52820278#post52820278
Go check it if you plan to root your TS!
[update] With the help of cheahcl, I got the latest F/W for 4th List 1/8/2100. With the MTK SP_Flash_Tool, I was able to upload a corrected F/W for my TS and everything goes back to normal!
Thanks for cheahcl for his dump and Lokifish Marz for his All in one tools! You guys really saved my day! (and my TS).
A Quick summary: Do NOT use any method on XDA yet to root or change TWRP recovery! It seems the TS of 4th list is different in some way than the ones before which render most of stuffs here invalid. However, fear not to play around since now we have a way to go back to stock!
In my experience, I found that it's really difficult to truly brick a MTK based system. The system will just reject flashing at slightest sign that a F/W is not compatible. The only cache is you need to have the "correct" F/W specifically for your TS!
In my observation, OMate made changes between each delivery. For Example, the 4th list of 1/8/2100 is different in (At least F/W configuration) of the 3rd or earlier 1/8/2100.
------------------------below is my original story of what I tried and failed--------------------------
Just got mine (1/8/2100) 5 hrs ago! I am on the 4th list. The delivery in FAST!
The watch starts normally. I played with it for a while, than decided to root it, install TWRP and apply the security hack made by +Lokifish Marz
Now I have a brick! Just after 30 min I receive the watch!
<<Can anyone help me here?>>
First of all, in respecting to all great DEVs, I have NO intention to blame anyone else but myself. (I did this to my own watch!)
Second, I have been rooting Android since Cupcake day, so I am not a Noob... (or so I think...) I am very familiar with ADB/fastboot... and use almost daily.
So here is the guide to brick. If Anyone have any idea please help me out!
--------------------------------------------------------------------------------------------------
1st, I tried to use this tool to root+TWRP+scurity patch http://forum.xda-developers.com/showthread.php?t=2713183&page=2 knowing it's NOT tested against 1/8/2100. I just tried anyway... The script went with a lot of errors, it seems the script cannot locate correct files but still push the security patched files into the /system/app (and other places).
I turn on the watch, but it just stuck at boot logo (the orange "Truesmart" logo without animation)
Also, the Recovery is still stock, TWRP is no where to be seen.
Since ADB still works, I adb reboot couple times, pull the battery, let the watch run for 2hrs, etc... Nothing works. The watch just stuck at the boot logo.
Than I follow this thread http://forum.xda-developers.com/showthread.php?t=2641261 and http://forum.xda-developers.com/showthread.php?t=2641261 with Stock firmware downloaded from http://d-h.st/users/Lokifish Marz/?fld_id=30814#files (Omate_1-8_2100_TrueSmart_20140328.zip)
I installed all drivers, restarts my Win 7 (x86) pc (several times), and after several attempts the Flashtool just flash in the Firmware.
The Tools flash with a green Check mark, indicating everything is ok!
However the watch just become a brick after this....
Than this completed the brick process! Now the watch won't even turn on, when I try to use Flash tool again, it always say S_FT_ENABLE_DRAM_FAIL. Google this and you find it's due to flashing wrong F/W, but I don't know where went wrong!
Anyone else have same problem or it's just me? Anyone have solution?
You said everything...
You made mistake but that shouldn't be problem.
You soft brick it using wrong recovery image and root tool but as you said, you had adb and fastboot on - so if you know what are you doing and I see you know (except of that pary of flashing something that's not for your device .) you should be able to flash stock firmware back.
If you can flash another firmware, try with other firmware...
Don't know what else to say....
Omate build piece of sh*t and we'll all have problems with it...
It's very hard to differentiate devices.
All of them has same nr on mother boards and, as I said, we will all have problems with Omate and their TrueSh*t...

Ha! Very true! I think you are right! I believe Omate have many segmentation on their HW/SW, even with same model number.... A lot of things changes between versions which makes the "factory image" not compatible....
Anyone has the latest (4th list) 1/8/2100 TS who could dump their whole image for me would be helpful...
I would like to help you but mine is 2nd list and it's still on customs office...
Omate shipment experts, you just gotta love them....

Not sure what to tell you on this. A board revision change is possible as the Omate_1-8_2100_TrueSmart_20140328.zip was from a 1/8 2100. I can't even test stuff anymore as I gave one to a tech student that's studying network and system security and the other four were stripped down, reworked into data gathering modules and then donated to near space projects.

Thanks Lokifish for your comment... Is there anyway to get a latest F/W? If you know anyone I could contact, please PM me... Thanks!
Anyone have yet received a 1/8/2100 on 4th list could PM me a Factory F/W dump?
I tried another XP PC with all steps checked and rechecked but still... No luck...
Teach me how to do a dump and I'll dump it for you. I was also looking how to backup my stock firmware before playing around, seeing as no one has our version of firmware uploaded for restore yet.
Also received mine yesterday and firmware version is 20140513, pretty damn recent.
You guys are going to have to help each other out on this one. I've already deleted 90% of any and all Android dev stuff from my personal file server and computer. This includes tools, guides and work going as far back as the original HTC Evo.

Thanks a lot! First of all, Currently don't do anything posted on XDA yet since most of them will not work with this version of TS... (This is where I am now...)
First of all, please get all necessary tools directly from this post "All Tools" http://forum.xda-developers.com/showthread.php?t=2734687 (Do NOT download or install any other things there!)
Follow those steps: (modified from link above)
1. Download "All Tools"
2. Install Universal ADB Drivers (included in All Tools) <--If you already have ADB up and running, it's not necessarily, then.
3. Enable USB Debugging on watch
4. Launch MTKDroid Tools
5. Connect watch to PC
6. Please follow the instruction from here: http://www.chinaphonearena.com/foru...up-MTK6592-MTK6589-MTK6577-and-all-MTK-Phones
   a. Skip everything above and just starts from "B) Open ADB prompt to begin communication with the phone" .
   b. Don't worry about the recovery thing... TS comes with a recovery which is not locked and you can do everything this article said with only stock recovery. (also no busy box is needed, nor su since TS run everything in root!)
   c. You could also refer to the video guide below for details
7. it's okay to just provide the file you got after finishing the step "C) Read back the ROM with MTK Droid Tools" I should be able to do the Step D) and after myself.
Thanks a lot for your help!

The space was given to me for free as a recognized developer and contributor. Seeing that I have left development completely, it is not right that I continue to use the services. So at the end of the week the files will be purged and I will ask the xda remove my developer and contributor status.

I've done step D as well, good to just flash it I guess.
Let me know if it worked, before I start messing about. I'm not good in all these stuff. Been flashing since HD2 days but still, just a tutorial follower, can probably count Linux commands I know with 1 hand.

Please follow this guide here: http://forum.xda-developers.com/showthread.php?t=2631953 under "IMEI Backup Procedure" before proceed anything dangerous!
After this, you are good to go! MTK is non-brickable (from what I learned for the past day... All you need is a corrected factory F/W!)

Ive managed to get my brand new watch stuck in a bootloop after using framaRoot to root it. (I know, I know)
Now, I am able to boot into recovery mode or factory, and tried a factory reset. No luck, so i'm pretty sure the issue is in the /system partition.
Does anyone know if there are zip files somewhere that i can flash from recovery, to restore the system partition?
Device:
- 1GB / 8GB / 2100MHz Version
- Originally unrooted
- OUI 2.1
- Modem Ver: MOLY.WR8.W1315.MD.WG.MP.V4, 2013/08/14 18:16
- No other modifications besides the rooting (which did work already before I rebooted)

The TS (or any MTK based system) does not use the usually "recovery backup/restore" way we familiar of, instead it goes the "special tool on PC backup/restore" method. You need ask people who receive their watch in around the same time as yours with same configuration to backup their watch FW with MTK tools than restore with said FW.
Basically what I had done in this thread!
Please follow my another guild to see how to do this...

Thank you soo much
And in case three smiley's aren't enough:
Also, quick note for other people bricking their phone, my issue (after I bricked it again), was that I used an app to change the density property, which broke the boot of the watch.
The app that broke my watch was: https://play.google.com/store/apps/details?id=com.birdapi.android.dpi

[Q] Kitkat to Jellybean S4

I'm new here and I need help.
Please if anyone can guide me on how to downgrade my phone from Kitkat 4.4.2 to Jellybean.
My nephew upgraded it for me and few days after I noticed my mobile data was not working anymore. Second I noticed was Bluetooth, it wasn't working either. I ignored it because I coud still use wifi, but a week ago it also gave up. My phone also restarts on its own.
I asked some tech and I was told it was because of the upgrade that is why I want to downgrade. Anyone who can assist me please? Or any solution that you know. I am not sure myself if the problem was caused by the upgrade. I tried checking videos on youtube on how to downgrade but I;m scared to brick my phone. I am not sure about the correct files to download and that sort of stuff.
PLEASE help.
I just want my phone working.
I tried to root my phone
by following a video on
YouTube and I think it's
already rooted.

Well, nope I don't think now you can downgrade your device from KitKat to JellyBean not possible at all because the boot loader may have been upgraded and if you even try downgrading the device by rooting your device it may results in bricking up. I would say rather than moving forward with the downgrading better would be to stay with the KitKat and keep your fingers crossed for the next update to fix most of your problems.

Depends on which variant of the S4 that you have. Some versions have ways to do a modded downgrade (not official via Odin like the good ole days...), but in general it's more trouble and risk than it is worth.
Thank you for your time and suggestions. I'd just want to add that my phone overheats even when it's off. And it also doesn't turn on anymore unless I connect the charger. I think its dying.

Did he update the phone officially or custom rom? By OTA or from the computer? I would reset the device and reinstall the latest firmware via Odin on the PC. If it was done via OTA, that can cause some odd issues, especially if the download was not 100% or reset during the process. It's always a good idea to reset when updating major versions, despite what the manufacturers tell you. I see it all the time at my shop and during my many many hours here on XDA researching and helping others.

Thank you! All I know is that he upgraded my phone using my laptop and using Odin.
Maybe I can upgrade it again?

Since you don't know exactly what or how it was done, it might be a good idea to post a screenshot of the About Phone section for us so we can see which update, if it's official, and all that.

What region are you using the phone in? It looks like the firmware is from Romania. Not that it couldn't work other places, but sometimes it works best to use a firmware and modem meant for the area you are using the phone in... Stranger things have happened.

I am in the Philippines and I don't know what firmware my nephew used.
I found video on youtube and did the same to my phone but nothing happened. I flashed my modem, it says on youtube, modem wifi fix, did it twice but didn't work. I also tried custom kernel but was getting error.
I don't know what to do anymore. It's just really very sad for a very expensive smartphone to not work. Bluetooth, mobile data and wifi are all not working. It doesn't turn on as well if you remove the battery unless you connect a charger.

I flashed my modem twice tonight, found a video on youtbe about modem wifi fix and it didn't work too. Custom kernel didn't work as well as I was getting an error.
It's getting depressing, I don't know what to do anymore. It's just that, it's an expensive smartphone without mobile data, bluetooth and wifi. It doesn't turn on as well if you remove the battery unless you connect a charger.

What happens when you try to toggle data? Does it turn on and right back off or does the switch to move to on not slide over or is greyed out?
I might try using Odin to install the Phillipines firmware, which you can find here:

Verizon Xperia Z2 Tablet will not update. Help, please.

Hello,
I just purchased a Sony Xperia Z2 32GB Tablet. I don't have Verizon, and since it is Wifi, I thought I would be able to use it just for Wifi. Well, I can use it for Wifi but I cannot update. I keep getting an error message. So, I think I just wasted a bunch of money, since this will be of no use to me now.
Do any of you have any experience to help me out? I would surely appreciate it. I don't know too much about this stuff.
Thank you in advance for any and all help!
What error message are you getting.
You do have a reliable connection?
Which firmware is on your tablet now?
Why would it be useless? There is no critical feature in 5.02 lollipop.

Thank you for your reply!
When I go to Settings > System Updates, I get "Error during DM session".
Yes, I have a very good connection on 5GHz and a very good ASUS router. I am next to the router and my network speeds are +75 Mbps.
I cannot seem to find and install PS4 Remote Play in the Google Store. That is one of the main reasons I bought it. Plus, I like to be updated to the latest version.

You said you use Wifi which is fine, but the tablet still supports LTE.

Thank you, but that did not work. I don't have a carrier. This device is strictly wifi and will not do a system update. It is stuck at 4.4.2. I really do not know what to do now. After researching, it seems that I am out the money I spent.

I seriously doubt that you have a paperweight. Have you looked into doing the update via PC Companion instead of WiFi. If all else fails, you can flash the generic Sony firmware (FTF). It wont root your tablet, but it will wipe it and bring it back to factory state like if it was being turned on for the very first time. I don't know your level of comfort but Sony tablets are pretty simple to understand ...as long as you're ready to do a little homework. Lots of Verizon customers are *****in about that error you got...your tablet isn't broken or anything

Thank you for your reply, again!
The tablet is set to factory settings right now, it is just that it is Verizon's factory settings. If I did the FTF, will it wipe out the Verizon stuff and give me the ability to update to the latest Android version? I do not know too much about tablets, but I will certainly be willing to give anything a shot. I really want it to work (well, maybe work is the wrong term since it is a running perfect, really) with the newest update.
Would you be willing to point me in the right direction, or give me a few pointers?
Thank you very much!

When going to settings >> About tablet ... What's your model number.
You could download the generic firmware from Sony for your particular model number and flash it using Flashtool. IT will wipe the Verizon image and load the Sony image fresh.

My model number is SGP561. So, if I were to do that, I could then update the OS and it would be rid of Verizon's junk? That would be amazing!
Thank you. I will look at the link you sent.

My files do not look anything like the files in tutorials, and I keep getting stuck on "Please move C:Flashtool/firmwares content to..." It will not let me do anything else. I will keep trying, though.
Edit: Do I need Java installed for Flashtool?

You really need to move all the FTF files from the old directory to the new directory or the message wont go away. Also install the drivers for your tablet. The exe for the drivers is inside the install directory of flashtool. I cant give you the exact path as my Flashtool is installed on a different computer. I don't believe you need Java installed.

I have installed the drivers, but I keep getting "Drivers need to be installed for connected device." Do I need to do something else? I have the tablet off, I hold down the volume down button and plug it in. Then, in Flashtools, I receive that error I posted above.
I fixed the driver problem and everything installed from FlashTool, but I still have Verizon stuff on here.

That's extremely strange, which firmware did you download?? Did it flash successfully, after the flash did the tablet take a good 5-10 min to reboot. Did you build your own FTF or downloaded another one...something is definitely not right..
The tablet does take a good 7-10 min to flash properly. image.sin is the longest.

Flashtools said it flashed successfully, but it did not go through a long time load before it rebooted. I am using Selected Bundle for Sony Xperia Z2 Tablet (SGP561). FW release : 23.0.1.E.0.208. Customization : USA. I followed the tutorials and created my own FTF. Do I have to check anything else other than the suff in Flashmode? On the screen while I am flashing in Androxyde, it reads "Upgrading, do not disconnect device from PC. Software status: Official". It says that I can unplug it, but the tablet still reads, "Upgrading, do not disconnect device from PC. Software status: Official".
After that is complete, I unplug, restart and it splashes to Verizon logo and all of the bloatware is still there and cannot update the system. I am stuck! Am I able to do this on a Verizon tablet?

It shouldn't make a difference, its Sony tablet first...Verizon just uploaded their own customized firmware. I flash my Sony phones and tablets a billion times, I don't recall ever seeing "Software status : official".
You said you were on 4.4.2 but if you flashed successfully, 23.0.1.E.0.208 is 4.4.4 ...does your tablet reflect the new firmware?

Actually, it is saying 4.4.4, but it is pretty much just doing a factory reset. Each time I flash it, it just resets and makes me go through the setup prompts and Verizon stuff everywhere.
Is it possible to use a different file from XperiFirm? I have the SGP561, but can I use the SGP512? They have a US version in the list. Do I need the LTE version?
