[Sony Xperia ZR] akash4357:
Firstly you need to unlock your bootloader. Google that, its easy. OR you can do it through flashtools (not tested).

Enable USB Debugging and unknown sources option on your phone before proceeding.

Download Flashtool, Open it. Flash the the kernel of an old firmware of Xperia ZR which was rootable.

Reboot your Xperia ZR after flashing. Connect to PC in USB Debugging mode.

Do not forget to close FLASHTOOL.

Extract the downloaded “DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip” file and run the “runme_win” file.

Follow onscreen instructions to root Xperia ZR and once it is rooted, device will reboot. Verify that you are rooted, run SuperSU app.

Now switch off your Xperia ZR. OPEN FLASHTOOL.

Now you need to flash the true kernel of Android 4.2.2 10.3.1.A.0.244 firmware of Xperia ZR.

After flashing, disconnect the phone from PC, reboot it and your Xperia ZR is now rooted

Official Thread
[Sony Xperia ZR] itandy:
So basically you're doing:

Use FlashTool to flash the 4.2.2 FTF

Downgrade the kernel by using FlashTool back to 4.1.2

Run the DoomLord rooting kit

Flash back 4.2.2 kernel using FlashTool

To flash the kernel you need an unlocked bootloader. What I don't understand is how to flash the kernel only? I found the kernel.sin inside the FTF file. Can I just delete other .sin file and flash the remaining FTF file?

Sorry if my questions are noob. :confused:
[Sony Xperia ZR] akash4357:
You need to keep the kernel.sin and bootloader.sin in the ftf and delete the rest. Also don't delete the META-INF file.

Official thread
[Sony Xperia ZR] djpeesh:
The problem is the bootloader? I thought doom's thread said that this was for locked and unlocked bootloader. Unlocking the bootloader will lead to a lot of people avoiding the root method.
[Sony Xperia ZR] itandy:
So is an unlocked bootloader NEEDED for this method to work for ZR? I thought DoomLord said it works for both. :confused:
[Sony Xperia ZR] djpeesh:
Have you managed to root through this method?
[Sony Xperia ZR] akash4357:
I did manage to root it, but then the phone suddenly restarts. Now I am stuck with bootloops. Strange as I managed to install Superuser from the Play Store.

Edit. I recommend not trying to root using this method. Wait till theres a definitive rooting method.
[Sony Xperia ZR] itandy:
I see you got bootloop from the other thread. Did you manage to fix it?
[Sony Xperia ZR] akash4357:
Bump.
[Sony Xperia ZR] djpeesh:
Yes. I fixed the bootloop issue. Need any help with the bootloop?

If you've got a bootloop, pull the battery asap as once it dies, you won't be able to flash ftf and the device will be bricked.

To fix bootloop [and still not get root access]

1. Open the 4.2.2 ftf file in flashtool.

2. Exclude everything [tick in the exclude box] except the kernel, and untick everything in the wipe box [data, applog]

3. Flash the kernel by pressing the volume down button while plugging in USB cable [DONT PRESS POWER BUTTON AFTER BATTERY PULL AS OTHERWISE YOU'LL GO BACK INTO BOOTLOOP]

4. After it flashes [should take a couple of seconds], reboot and you should be back to normal

I REPEAT PULL THE BATTERY IF IN A BOOTLOOP OR YOU'LL LAND UP WITH ANOTHER PAPERWEIGHT
[Sony Xperia ZR] itandy:
I just learned a lesson! Thanks!

So again you're not successful in rooting 4.2.2 using the kernel switching method?
[Sony Xperia ZR] ujwals:
i think the kernel switching fix will not work on ZR.. we don't have a rootable 4.2 kernel

i think the 423 kernel is 4.2 :rolleyes:
[Sony Xperia ZR] grim_ripper:
I am trying to get 4.2.2, but after flashing the system rom on step 4, I got into a boot loop. I can't seem to use flashtool to recover, Please help! I can't even get to recovery

EDIT: Now I am going somewhere I think, but I don't know if this is serious, I get this from flashmode now

ERROR - Error in processHeader : 1 : Incorrect function.

ERROR - Error flashing. Aborted

EDIT: I think I bricked my device =(
[Sony Xperia ZR] BarajaVLC:
It happened to me also, but it's possible to recover from it.

Install PC Companion on your PC.

Go to Support Zone.

First option -> Update phone / tablet software.

You will see a underlined link that says "repair phone / tablet"

Just follow the instructions.

You will need your phone to have at least 50% battery level. Take out the battery, insert again, and connect your phone to your PC via USB while pressing the Volume + button. You will hear a sound coming from your PC meaning it's been connected.

Sony PC Companion then will flash your phone with the latest firmware. It takes a while and you need to have internet connection, but it works.

As you flashed the Russian system rom, the firmware installed in your phone by Sony PC companion will be the Russian Android 4.2.2. No problem with this as it includes all the languages.

Do this as soon as possible as you need your battery charged and you can't charge the battery in your phone while in the bootloop state.

-------------------------------------------------------------------------

-------------------------------------------------------------------------

I'm not sure what we did wrong to be stuck in a bootloop, but after my ZR being reflashed by Sony PC Companion I just flashed the Nordic 4.2.2 ROM and my phone remains unrooted until there is a easier method to get root :o
[Sony Xperia ZR] itandy:
In fact you should read the other thread for a workable root method for 4.2.2. This thread is very old and AFAIK this method doesn't work.
[Sony Xperia ZR] grim_ripper:
I will try that when I get home, hope it works!

EDIT: That was the thread that I follow, I thought you meant to say that thread was old. I posted here because of the bootloop, no one encounter it over on that thread

EDIT2: I realize that flashtool doesn't work for me for whatever reason, keeps giving me the error in processHeader, invalid funtion. Should I be using xperia A or xperia Z during install? I have two drivers listed in device manager, sa0101 and sa0104. Should I re-install drivers? I suspect this is the reason why PC Companion couldn't help restore my phone
[Sony Xperia ZR] djpeesh:
Managed to get root using vroot. It's very easy and quick, if you follow the instructions.

I think it's only windows though.
[Sony Xperia ZR] shteren:
djpeesh, perhaps you can write a small guide for rooting using vroot?

many people are having a hard time rooting 310 version and than flashing the 244 with CWM etc.

can help a lot of people.

thx it worked on c5502 4.2.2 , no problem
[Sony Xperia ZR] nikhilkaushik:
Guys just to remind you people, that unlocking your bootloader, your people will not be able to use stock roms, or even if u install, bravia and Walkman won't work.... Its better to downgrade, root without unlocking, take backup of TA partition, then upgrade, so that even if u want to go back to stock, than you can lock your TA partition and nor your warranty is void.... Backing up TA is most preferable here in the matter of Sony......
[Sony Xperia ZR] Ofcos:
i did root with out unlocking.... just follow the instructions
[One (M7) Q&A, Help & Troubleshooting] dlads:
Been using my HTC One now since it's release day and although I wasn't a huge fan when it came out, it's grown on me like moss and i'm now 100% confident that I made the right choice in getting this instead of the S4.

However......

On my daily commute to work, a journey I've been taking for over two years now, I seem to have less signal than all the phones before this one ?

It's the same sim card, same number and the same network.

What happens is the signal will go really low to around 1 - 2 bars and the mobile data connection will teeter around Edge and 3G and come back up to H in parts.

My previous handset as you can see from my signature was a galaxy s3, it didn't ever drop below 3G, was mostly on H and never once went to Edge, on the same trip for well over a year, I've also used an EVO 3D which acted in the same manner as the S3, but the HTC One is really annoying me now as I'm not able to check things on the internet and such, which I've been able to do for as I said a few years now on previous handsets.

I'm currently on Venom rom 1.2.1 and I have an Orange Sim card in the UK.

My baseband is 4A.13.3231.27_10.31.1131.05L

I did try another Radio, however it had little impact on the reception and I was just wondering if anyone else had witnessed similar drops in signal quality themselves?

I'm using a case too, I have three, Double dip flip, Double dip and a silicone case, I've also had the phone without a case and it makes no difference at all.

Any help or thoughts would be appreciated.

Thanks.
[One (M7) Q&A, Help & Troubleshooting] spottarget:
same problm

I'm in the US , recently unlocked my but but mine all of the sudden drops from 4 bars to no signal. I have noticed that while I have WiFi on, the network signal seems more stable. I've been reading a lot of ppl have the same problm.
[One (M7) Q&A, Help & Troubleshooting] ragingredbull:
I am on TMo in London. When I first got the phone my signal was awesome. I had H with 3 plus bars all the time all the way from home to work, in work, at home. Since the update I have the exact same issue as you. I lose signal completely, it goes to E a lot of the time now. All in all a very poor experience. I was thinking of installing the original radio to see if that would do the trick(I think it was mentioned that the new update had a new radio). I just do not want to root and lose my warranty. I am getting pretty p'd off though so may just take the plunge
[One (M7) Q&A, Help & Troubleshooting] ro_explorer:
I'm in the same boat with you guys. My signal varies a lot from H+ to 3G and E and few times is just disappearing completely, taking a good 1-2 minutes until it comes back. I tried like 4 different radios, all with the same behavior.

I'm on GE 4.3 ... stock.
[One (M7) Q&A, Help & Troubleshooting] rrahul963:
issue solved

I was also facing the same issue. Finally realized that it was because my network setting was on GSM or WCDMA i.e. 3G.

I changed my network to 2G and everything is fine.

try this out.

Ok the stand alone EXE doesnt work for me. It requires that I plug in a power adapter that is already pluged in and because of this I was told that I need to do it the SD card method.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] SierraGT:
Hey everyone!

Longtime lurker/first time post here. I have had the very unfortunate experience of pulling my S4 out of my pocket to check the time only to have my heart and jaw drop at the sight of a broken screen. It seems to be the same problem that others have reported where the glass is fine but the touchscreen is cracked, starting on the right side directly at the power button.

I have NEVER dropped this phone. It has been handled with great care at all times. It was always in an Otterbox Defender series case. Nothing out of the ordinary has happened to it while in my pocket (bumping into something, etc) and there was never anything else in the pocket with it. I have really enjoyed this phone and was mindful of it at all times.

So... where do I go from here? I'm looking for some good advice before I take a next step in trying to get a replacement. I do not have insurance on the phone (yeah, I know), but the price each month plus the deductible for a refurbished phone didn't sound like a great deal to me since I'm able to take care of my things for the most part. If it was an accident, I'd bite the bullet and replace the screen myself or get a new phone but this either a design flaw or a manufacturing defect. Has anyone here had success through Sprint or Samsung in getting a replacement or repair? I'm rooted and running The Blu Kuban right now. Do I need to try to ODIN back to stock for warranty purposes before doing anything from here or is there a better option for me? The phone works but I can't see or operate the screen in anyway.

Any advice would be much appreciated. Thanks!

Google... 1st search result.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
Are you a homeowner? Try your homeowner insurance. I added coverage for my phones, tablets, and laptops that cover all loses. I think it only added $15 a year to my cost and the deductible is only $25.00 on a replacement. Maybe your insurance may cover the cost of a replacement phone.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] SierraGT:
Thanks for the useful reply Joe! How did I possibly forget to search for information on the subject before going through the trouble of making my first post on XDA despite being here for awhile?

Seriously... Read the thread. Its filled with disagreements as to what has been successful and turns into accusations of being too rough on the phone. I was asking if anyone here has successfully gotten their phone replaced and what to best method of going back to stock would be without being able to use the screen at all.

Cruise350 - Thanks alot for the suggestion man, but I'm not a homeowner.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] shizkoff777:
I know when I got my replacement for my evo 3d it wasnt refurbished it wasn brandnew still in the box and seals were not touch.Im hoping that the flaws in the screens are just because it was early in production.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Esoteric68:
More and more insurance companies are offering tech insurance and it is very affordable. I don't carry Sprint's insurance either (bad experience many years ago) I generally just keep my newest 'old' phone as a replacement in the event my new phone gets broke or dies.

It pays to shop around (or google) in trying to find good ways to insure devices. I realize this doesn't help you in your current predicament but perhaps for future reference.

You might search youtube for similar experiences which might tell you how they were fixed or offer affordable solutions for replacement.

Good luck.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] oscarthegrouch:
Search YouTube for complete galaxy s4 teardown. A replacement screen and digitizer and frame is about $241. I've watched the 37 minute process on the video and feel it is way beyond my skill and patience. I don't know what else to tell you other than insurance might have made this easier and more affordable. Depending on where you go, who you deal with, who you talk to, this process can be expensive and full of hassle. Might I suggest, when you do get a replacement, that you invest in a tempered glass screen protector. There are topics in the accessory section on this topic. It will help protect your device better than simple screen film.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
The one common theme in all these broken amoled screens under the glass are pocket users. Not one of these posts have come from someone that uses a case with holster. The gorilla glass on these phones is very strong, but the screen underneath can flex while in your pocket. I know everyone says they don't abuse their phone, haven't bumped it in their pocket, don't carry anything else in their pocket, but something that is happening is flex. With the plastic back of these phones they will definitely flex while you sit, bend, walk, or whatever during your normal routine. The amoled screen probably has a limit to the amount of flex it can handle before it fails. I know, you didn't abuse your phone but calling it a manufacturers defect is just ridiculous. Suck it up, fix or replace your phone, and next time don't put it in your pocket.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] SierraGT:
Just to clear this up... I did say design flaw or manufacturers defect. I've had many phones over the last 15 years. I have never had one break in anyway except for my Samsung Epic 4g, which took a 2 story fall (while in my pocket lol) onto a very hard surface. All it did was crack the screen a bit but was still functional for the next year until my contract was renewed.

To say that I should expect a $650 dollar phone in an Otterbox case to completely break to the point of not being able to use it just by being in my pocket in normal everyday situations is RIDICULOUS.

Should consumers really expect this level of quality? Imagine if a salesperson told you this as you were thinking of buying a phone... "Now just to let you know, never keep this phone in your pocket and then sit or walk because it'll break." :eek:

If this phone breaks in peoples pockets and isn't intended to be there, then Samsung would've/should've provided holsters with the phone.

Straight from Samsung - "Offering a highly crafted design with a larger screen and improved battery life, the sleek and innovative Galaxy S4 is slimmer yet stronger, with less to hold yet more to see." Sounds like we should expect a strong, well made phone. Not a something that will break this easily. My phone looks exactly like 4 other pictures I have found of other user's broken screens... all at the exact same spot. I maintain that this is either a design flaw or manufacturer's defect. Yes, as you said - the gorilla glass is strong. I just wish they would of made the frame stronger. Then I'd still have a working phone.

Btw, I am an unabashed Samsung fanboy. TVs, last 3 phones, monitors, etc. I talked 4 different people into getting this phone after I had it. I think normally Samsung makes great products with a high level of quality but they made a mistake on this one. I'm no longer looking forward to the S5 that comes with the required fanny pack... well, not until they make this situation right.

Now... does anyone have any info on my question on returning to stock? Thanks!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] BiffTirkle:
This is a tough one. I'd suggest at least attempting to contact Samsungs warranty dept. Perhaps they can offer a better solution than sprint.

Back in the Treo days I actually sent in a phone or two to palm, and got refurbished replacements.

The tough part is your defect.

I provide warranty work for appliances, manufacturers know or believe they know how and why something has failed. Glass stove tops are a prime example. Whirlpool will only cover heat fractures. I have to submit pictures of the top and, 99% of the time, the claim is rejected. Mostly because these tops break from impact or improper installation.

Point being, if you send your phone to Samsung, they may not cover it. But if you're optimistic and patient a few minutes on the phone may yield positive results.

http://m.samsung.com/us/support/service/warranty/SGH-T959HABTMB

Definitely unroot and return to stock.

[Nexus 7 (2013) Q&A] Snow_fox:
Out of curiosity why isn't root allowed out of the box on the Nexus 7?

I mean I get that no one should use superuser access/root privileges on anything more than a "need to use" basis and honestly, I'll even admit that with the way the ecosystem has evolved, root isn't really entirely "needed" but, it still boggles my mind that there is no way I can just open up a terminal, type in a code, and get root.

I've tried googling the issue but, I generally get a bunch of responses about things which aren't quite related.
[Nexus 7 (2013) Q&A] firesoul453:
I think its fine the way it is. its jailbroken out of the box so you can use your device how you wish and that is what matters. You can't expect a company to support users to change everything about it. Then people complain about bricked devices or contact them for support for some custom rom.

However I believe they made it pretty easy to root. They certainly could have made it a lot harder. Anyone who has the skills (or patience to learn how) to use root certainly can root a device based on the tutorials given. And other users who don't want to worry about it don't ever see it. The little bit of effort helps weed out the people who would mess things up for themselves.
[Nexus 7 (2013) Q&A] Snow_fox:
I don't expect a company to support me changing anything I want about it. If I misuse root privileges, then I don't expect to have a lifeline when I call asus/google. I don't expect say Dell or HP to cover my PC if I try to install ubuntu and I botch something up.

However, refusing to let me have root because "might" mess something up is also flawed logic. I may also for one reason or another need root access.

While I am glad they make it easy to root, the reality is there is they are being counter productive. Honestly, just leaving in root access would decrease the chances of me bricking my device at this point. As of now to get root access I'll have to flash a custom recovery compared to just giving the ability to go into a terminal and type in "oem -su enable" or something.

If the flashing issue is really that big of a deal, then why force users to flash to get what they want in the first place?
[Nexus 7 (2013) Q&A] firesoul453:
Root can cause problems. It can cause security problems if not used right and can brick not only while rooting but while flashing custom roms and things.

while you and I don't go asking for support, a lot of people do. People try to pass things off as warrenty problems and do call and email asking for support for things not originally on that phone.

And it hurts them in other ways. Google makes pretty much all their money from ads. Rooting makes it easy to block ads and you average rom might have it built right in. The only reason google bothers with android was for the ad money. So there is no incentive for them give root out of the box. They already are more open and free than their main competitions.

You could look at samsung. THey make their money of the hardware and so have been more open with rooting with odin, thought they still don't really care for it (probably because of the support issue)

And the carriers are even worse because rooting allows for things like wireless tethering for free and data is their biggest costs. Their certnaly isn't any reason for carriers to push for root.
