[One (M7) Q&A, Help & Troubleshooting] asdqwe143:
hey there guys.is there any other way around on upgrading Firmware version without using adb or connecting to a pc through usb? cause my M7 has an issue where it cannot be detected anymore (or so i know/havent found a clue on how to yet). Meaning, whenever i tried to connect it to a usb through a pc or laptop.it switches automatically to “usb phone host mode”,disabling the charging and stuff, i have to boot to safe mode just to make my phone charging enable again. ,so using ADB for me is kinda like not an option..so any tips,, thanks in advance

Hi guys,

I'm currently running official 3.09 on my Z7 Max, with Gapps installed via TWRP.

I saw that there are some newer udpates (3.19/3.20) - can someone tell me the difference?

I'm not sure I want to reflash my phone etc if its not worth it.

Thanks!
[ZTE Z7, Z7 Max, Z7 Mini] pnin:
After being on v3.09 for a while, I'm now on v3.19 and do strongly recommend it. :good:

It might be easier to jump to v3.20, though...

Please tell us how it went.
[ZTE Z7, Z7 Max, Z7 Mini] TopTomy:
Hey, thank you!

how would it be easier to jump to 3.20? can I flash it straight on 3.09? if so, can you link me please?
[ZTE Z7, Z7 Max, Z7 Mini] pnin:
Please look for my report thread in the "Help and Troubleshooting" subforum... Can't link it right now, I'm on my phone.
[ZTE Z7, Z7 Max, Z7 Mini] linom:
I flashed over 3.15 with TWRP without any issues. However I noteiced that 3.20 has GPS fix issues.

Take a Nandroid backup as always
[ZTE Z7, Z7 Max, Z7 Mini] petrofsky77:
Hey guys, I am currently on CM12.1, but would like to try out the Official ROM for Z7 max. Heard the version 3.22 is super stable now. How do i go about in installing this? Do i need to flash v1.64 first and then work my way from there? Is there a faster route where i can just jump to the v3.22 ROM without having to install the ROM in sequential order? Any kind of help is appreciated.

Thanks.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] Failhoew:
Hey guys!

Ive been trying to figure out how to go about rooting my tablet but since I am new at this stuff I just want to make sure I dont **** up ;)

My questions are:

1. My tablet is 5.0.2 atm, as far as I know I have to downgrade to be able to root?

2. If I need to downgrade I believe I need a FTF file, I have a LTE version which is bought in sweden. Do I need a specifik FTF file for my country or can I use http://xdaforums.com/showthread.php?t=2741233to downgrade my tablet?

3. Can i still use this guide http://xdaforums.com/showthread.php?t=2792056 to root my device after I downgraded the firmware or is it outdated? If its outdated is there any updated guide I can use?

Any help is appreciated!
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] kulvertti:
1. There is this: http://xdaforums.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461. But it ain´t give proper root and there is also some security concerns with it but your decision.

2. Yes. You need FTF file which is 4.4.2 firmware for you device. Latest rootable is 17.1.2.A.0.314. Here is download link for SGP 521 if you want. https://mega.co.nz/#!cN5ykLrL!0w38j4lWIHFm1rZdwexScG9Cpz2BghrSZPpLRkyTcL8 . However your link should work also. If you only use it for rooting it don´t have to be for your region.

3. Your link would work for rooting properly. However there is other methods too.

4. After you achieved root just install custom recovery for you device and flash latest prerooted firmware for your device with it and you are good.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] Failhoew:
Thanks for the advice man!

Ill give it a shot today :)
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] nathlynn2201:
Alright mate would this work for me as I took it that I need to unlock the bootloader to install a custom recovery?

http://xdaforums.com/showthread.php?t=3159705

Thanks
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] kulvertti:
There is no need to unlock bootloader if you just want to root your device. Bootloader unlocking is needed if you want to try custom kernels or roms that use custom kernels. And yes this work for your device also.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] nathlynn2201:
OK so with a locked bootloader I can downgrade to 4.4.2 for my region model root using kingroot..? Then install a custom recovery without having an unlocked bootloader then flash Pre rooted ftf lollipop ROM build. Is the updated kernel and firmware in the Pre rooted stock ROMs? Thanks.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] kulvertti:
Yes you can downgrade to 4.4.2 firmware with locked bootloader. After that you don´t need kingroot to root your device because [MENTION=4904057][NUT][/MENTION]´s dualrecovery pc installer can root your device before it install custom recovery. After that you can flash prerooted firmware (= .zip file) with custom recovery. Usually prerooted stock roms has whole firmware including kernel. Their also include SuperSu and custom recovery. And there is no need to unlock your bootloader in any step for this unless you want to do that.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] nathlynn2201:
OK so I flashed a ftf file from this thread http://xdaforums.com/showthread.php?t=3061431 I don't think its right as its for HK etc. A 4.4.2 ftf. 17.1.a.2.402 HK/sa/as/kw.

I was on 23.1.A.1.28 in the UK as O2 UK being the 4g network. But according to that thread the 23.1.a.1.28 I was on is generic HK so I'm confused. How can I get back to my original then? Thanks
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] nathlynn2201:
Just made my own xperifirm ftf file the guide I followed on xperiblog said not to add the ta partitions is that correct would you know?
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] kulvertti:
I have tried both ways. Including ta partition and excluding it. Both works just fine for me.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] nathlynn2201:
OK thanks I did it without the ta partition like suggested but wasn't sure if it was 100% correct. Should all be fine though. I'm currently now rooted and all fine but what I want to do is have a Pre rooted flashable zip of my ftf I've made so it is my actual stock ROM I'm running. I've looked into the prfcreator but don't wanna do it and run the risk of bricking my z2 tab. Have you used prfcreator? I guess all I need is my ftf file to use. The most update supersu zip I want. And then I need to somehow have the xzdualrecovery.zip but not sure if that's all I need or if I need the current Sony signed kernel or what. Thanks

---------- Post added at 05:50 PM ---------- Previous post was at 05:35 PM ----------

Must admit reading up more looks pretty straight forward as I just use NUTz xzdualrecovery flashable zip as the recovery zip. I'm just unsure on whether I would need to check kernel otakernel modem and ltalabel for our device. Thanks
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] kulvertti:
Depending what you want but if you include everything else but signing you end up to fully functional prerooted firmware.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] nathlynn2201:
Sorry mate if I use my ftf and super su.zip and xzdualrecovery.flashable.zip then add all checks do I also have to get it signed? Or I can do all checks and not need signing and it will be fine...? Sorry mate first time and all just trying to work out different things thank you.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] kulvertti:
No need to be sorry. You don't need to sign your zip because TWRP can handle unsigned zip files just fine. There is nothing wrong to sign your zip file but some times it can cause problems. Your choice.

My Universal just died, without a warning, 1 years 6 months 5 days (bought 26 December 05 to today 1 July 07).

It just cannot power up anymore.

All my data is inside, last backup is few weeks ago, how to get my data?

Anyone had this experience with it just died without doing anything?

@Midget

How did your died?
[JASJAR, XDA Exec, MDA Pro ROM Development] davicito13:
battery? ;(

How it's possible?
[JASJAR, XDA Exec, MDA Pro ROM Development] tailazoom:
Mine suddenly died after 2 years, no way to power it on even with the charger. But i just replaced the battery and it came back to life!
[JASJAR, XDA Exec, MDA Pro ROM Development] CWKJ:
Nothing helps.

I have 3 batteries,

1. 1 half dead battery (half dead after 6 months of use)

2. 1 used for long time battery (the current regular used with care for about more than 1 year and Universal died with)

3. 1 new battery which bought and tested working not too long before this incident and a hardly used spare battery.

Before my 1st post above, tried everything.
[JASJAR, XDA Exec, MDA Pro ROM Development] CWKJ:
When putting in the charger, do you see a permanent RED Led instead of regular Orange charging status Led?
[JASJAR, XDA Exec, MDA Pro ROM Development] Midget_1990:
the screeen co-axial cable has gone in both of mine (im a heavy user when it comes to that ;) )
[JASJAR, XDA Exec, MDA Pro ROM Development] akpe:
That happened to me. I just got a new battery, and even it sais it is 100% charged in WM, when I plug it in to the charger (PDA on standby) I get a permanent red light where the charging status is for a while, and then the device boots up and the orange light is back. I suppose I should let it charge till the orange light changes to green and then use it?
[JASJAR, XDA Exec, MDA Pro ROM Development] CWKJ:
As I say I have 3 batteries.

The regular battery (the 1 year old one) which I am using is like the situation you describe at battery Low situation, trying to charge but fail.

But is there an explaination why my new battery does not work too. Measured across voltage is 4.2V

I have also measured from the USB to battery point, the 4.2V voltages are there.

The RED Led is always RED when charger is inserted. Without charger, no Led.

Is the RED colour LED software or hardware controlled?

How is the battary voltage connector connect from battery to the board.
[JASJAR, XDA Exec, MDA Pro ROM Development] CWKJ:
Between, if it is free, which will you choose,

1. Dopod U1000

2. Dopod 838 Pro

3. Dopod D810

4. O2 Atom Life

5. O2 Flame

Actually I would like to have Karser or Omni, but not here yet.

Still no phone yet, using my old Nokia 6170 which I grab from my angry son. Hee Hee
[JASJAR, XDA Exec, MDA Pro ROM Development] Hewlit:
you should go to a specialized service.

probably there is something to do and to rescue your device.

it shouldn't die just like that. that's why i think that a replaceble component died. but a replaceble one.

also, i read something about batteries on the internet.

for PDAs it is adviceble to charhe them whenever possible.

so if you have 90% of battery left, you should charge it.

this is the oposite for regular phones where is adviceble to

drain the battery and only then to charge it (for maximum life).

but you should never let your device over night with the charger plugged in,

or for a longer time that it is necesary to reach 100%.

Hi CWKJ,

You could try xda repairs, they may even send you the parts for DIY.

Cheers,

Beast
[JASJAR, XDA Exec, MDA Pro ROM Development] CWKJ:
Ok, here is the full story.

My Universal is still cover with special paid warranty which I have a choice for repair or change a new device. In case of my choice is to repair, I will not have any choice of new device for future failure of Universal.

I am lazy to do it myself and Universal is going to be end of product life and service part here.

The repair agent said that both my LCD and Mother Board needed to change, any combination of new and old does not workl

The choices of newI have is Dopod U1000 (need some $ topup), Dopod 838Pro, Dopod D810 (I like this very much), O2 Atom Life and O2 Flame (the obvious choice). But my interest is in Omni or Kaiser.

Before sending for Agent to check what is the problem. I make some analysis myself.

The problem is it never power up with neither of my 3 batteries. Measured Voltages coming from USB to battery contacts, 4.2V is there. So that means this voltage going into the Mother Board has problem. So I tried to charge one of my power low battery as suggested throughout the night. Interestingly the Universal Alarm went off in the middle of the night and my whole family was up. At this time, the LED was green and the Universal was up and it is warm from the charging. So I thought it is alive. But the next morning when I woke up, charging is completed and Universal is no longer warm, it is RED LED again and it never wakes up. The voltage across the batteries are all 4.2V.
[JASJAR, XDA Exec, MDA Pro ROM Development] omega_:
Why don't try borrowing a teseted functional battery from a friend to do a test? I get the red LED light problem when the battery isn't inserted properly or if the battery is faulty.

What I do is to remove the battery, and reinstall it and everything works again. I don't think it is the motherboard problem, otherwise the red LED illuminate.
[JASJAR, XDA Exec, MDA Pro ROM Development] chriswo:
I think what CWKJ is experiencing with his Universal is quite similar to my Xda II a couple of one and a half years back. Service center claimed that I should replace the mainboard, but I think they were just looking for the easiest way out - when it could just be one or two component that does not pass the electricity through.

So, somehow I still hope someone could revive my Xda II which is now sitting inside the drawer as paper weight - I now am using Universal.

Hi, i have a Samung S2 Plus ( 9105P ) which worked fine untill few days ago.

After a wall charge phone only boot directly into recovery, i can't get into download mode, tried wipe / factory reset without any luck, removed battery and tried again to boot it.

The phone has stock rom, the only option that i see now is too try to fix it with adb sideload from recovery. Did try to install CMW with sideload but usigned error ocurred. Is there a way to install custom recovery with sideload or any other option to try revive this phone ?

[G2 Q&A, Help & Troubleshooting] adaimespechip:
Hey guys,

Im trying to get my G2 to run the latest MIUI release - however i've run into some problems.

Background:

- D802

- Running Cloudy 3.2 (L)

- TWRP 2.8.6.1 installed and working

- MIUI ROM - Author: gtbluesky Version: 5.6.20 (MIUI6） Size: 886.29M

So I boot into Recovery, Flash the ROM, Wipe caches, wipe data, wipe system, flash the ROM again for good measure, reboot.

At this point, the device sits on the MIUI boot screen forever - it does not boot.

What am I doing wrong here? I think, the issue could be that the ROM above is based on KK and not L, where as I am running L. Does this mean I need to flash the KK Bootloader before I flash the MIUI ROM?

Im going to attempt to sideload and reflash Cloudy in the mean time, but I assume that using autorec to flash a KK BL and THEN booting into recovery to flash MIUI would fix the issue?

Any help appreciated..

EDIT:

_ can access the device via logcat, and can use fastboot/adb etc. I'm now back up and running on Cloudy thanks to adb sideload.

I'd suggest Anker batteries. I've used their normal ones and the're pretty good quality and not too expensive. Though, be prepared to double your phone size using any extended battery.

I think he's right. It would be very difficult to change only the digitized. It looks like you need to replace the entire display assembly.

You can't change the digitizer without damaging the amoled screen.
