[Q] Xperia U won't go in recovery mode - Sony Xperia P, U, Sola, Go

Hello,
I have a Xperia U, and I found a nice ROM for it, MIUI. The problem is, that it needs to be in recovery mode. I tried all the ways to get there, but it keeps failing. I did it with ROM Manager, Quickboot and just via the buttons, but it keeps just booting normally. I know that my bootloader is not unlocked. Is it nessecary that it is unlocked, for it to go in recovery mode?

Usually these roms require unlocked bootloader. But sometimes developers manage making these roms for lock bootloader also
I just found the thread for miui based on locked and unlocked bootloader.

Okay, but now I have another problem... If I want to unlock its bootloader, it needs to be in fastboot mode or something. It will only turn the left led blue. Then I should install drivers. The problem is, that it won't stay in fastboot mode long enough for me to install the drivers. Am I doing something wrong??
Pls help me.

No mate. you are not doing something wrong. You have to be really fast. You can try another method too. Right click on computer and click properties. Open device manager. Now connect your phone on fastboot and when you see your device on device manager screen do the magic and install drivers.
This is the tutorial on how exactly unblock bootloader. http://forum.xda-developers.com/showthread.php?t=1527159.
Remember that unblocked bootloader means void warranty!

Yes you should be able to flash wizard love rom or the rom that your device was shipped with.
Just download either of these roms then put your device into bootloader mode. Make sure that the word USB is visible in the lower left corner of the bootloader screen when you plug in your usb cable. Then you just have to execute the installer of the rom that you downloaded.
If you get an error message you can use precautionary measures such as killing wcescomme.exe in task manager, turn firewall off, remove memory card, reboot pc etc.
Good Luck
Thnx for reply.
Eqx also just sent me mail and told me the same thing.
I am just busy charging the battery before i attempt another go at repairing the phone, i want to make sure that all goes smooth this time.
Will post my sucess or failure when i am done.

Phone stuck on BootLoop with No Recovery/Usb Debug

My phone is stuck on bootloop. I have cyanogenmod 13 installed on my moto g 3rd gen(2015). I can't seem to get into my system recovery either, which is now twrp and it just shows the logo for twrp recovery. I also for some dumb reason disabled my usb debugging mode, so i can't flash my phone either. Help plzz

So, if you turn the phone off and then hold "power" and "volume down" untill it boots, nothing happens?

of course, it goes into bootloader but my PC can't recognize anything. So I can't flash anything. USB Debugging is disabled. If there was a way to force connect that would be great

You don't need USB debugging to use fastboot when your phone is booted into bootloader. What you need there is a fastboot tool and drivers. I'm using this one:
http://forum.xda-developers.com/showthread.php?p=48915118
and if it doesn't install correct drivers for you, you can get them here:
https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481
first thing to do is check what fastboot returns after this command:
Code:
fastboot devices
if it shows your device ID you're good to go
I'd suggest downloading stock firmware first and flashing it before messing with custom recovery. Just remember Motorola often updates bootloader with new firmware so don't flash anything older than you had on your phone before.
Good luck
EDIT: you can also use RSD Lite to flash a new software, it basically automates fastbooting proccess, so theres no risk of misspelling or doing other stuff wrong
EDIT2: firmware is here:
http://forum.xda-developers.com/2015-moto-g/general/index-moto-g-factory-firmware-images-t3169639
also, the OP (lost101) is a great, helpful guy who may give you some advice if you need
Thanks I'll give them a try

Flashtool only detects fastboot mode, stuck on Sony logo

Hi there,
my mate gave me his Xperia Z2 asking if I could fix it. He said it's stuck in boot loop. I thought it'd be an easy fix but I am experiencing a problem that I think (I hope I'm wrong) is hardware related.
The phone is indeed stuck on the sony logo and won't go past it. It responds to power+volume up (buzzes 3 times). I can put it into fastboot mode (blue LED, flashtool recognizes the phone in fastboot mode). However, I can't put it into flashmode (LED goes green, but flashtool doesn't recognize it, Windows and Sony Companion doesn't either btw).
Has anyone had this problem before and knows how to fix it or is it indeed a hardware issue?
TIA guys
Cheers
Edit: All the drivers are installed, I have tried two different computers, previous flashings were no prob.

Is the bootloader Unlocked???
If yes then try flashing a kernel that has built-in recovery and clean flash a new rom
It may helps
Hi, thanks for the reply. I'm afraid the bootloader is still locked, tried to flash a kernel already, it won't let me so I assume it's locked.

Maybe you can unlock bootloader and then flash a kernel(try it at your own risk)
Okay, thanks, will do that. I would have liked to find a way without unlocking the bootloader (wanted so save keys first) but it seems that it's the only way since I can't make it into flash mode. Will give an update after!
Hi there.
Unfortunately I couldn't unlock the bl. I assume, USB debugging isn't enabled. Any ideas?

I think there is some gadgets out there that will force your phone to boot to flash mode(im not sure) or you can search "how to force Xperia phone to boot to flash mode" it may helps
If you cannot access fastboot or flash mode there is nothing you can do
Cool, will do, thanks.
Just to clarify: I can access fastboot mode fine, it's just flash mode that isn't recognized! Will post an update.

Ah, I see. Well, anyway, I tried to find a way to force the phone into flash mode but nothing worked. Very annoying but I think I'm gonna call it quits.
Thanks for your help anyway, appreciated!
It seems like a firmware issue than a hardware one.
It's either falshtool compatibility issues , a soft-bricked phone or both.
1 - Try using an older version of flashtool like 0.9.18.6 and see if flashmode works.
2 - If you know the current firmware version
you can just flash the stock,signed kernel via fastboot.

Are you sure you have the proper flashtool drivers installed? What's the Windows and Flashtool version? And have you connected any other Xperia device in flashmode mode to the same pc before?
I am saying that it is 90% a driver issue..
-Try disabling Driver signature on Windows 10 or 8 then reinstalling Flashmode AND Xperia Z2 drivers from the folder drivers in the main flashtool folder, then restart the pc..
- Try connecting a different USB cable
- Try connecting to a different USB port..
- And when you want to flash the firmware.. Select flash.. Select the firmware.. Check the wipe options (optional).. Press flash.. And after that when flashtool asks to connect the device in flashmode connect it.. Do not connected it BEFORE pressing flash..
Hope this will help you.. Have a good time..

I have the answer, same problem, and got into TWRP Recovery:
1. Obviously, ADB, Fastboot, Drivers, flashtool installed (In windows 10 you need to disable driver signature enforcement, which resets after reboot)
2. Download techerrata.com/browse/twrp2/sirius , and Pick Stock kernel Repack ( credits to Dees_Troy https://forum.xda-developers.com/showthread.php?t=2772879)
If flashing anything via fastboot fails (too many links, not allowed, no permission etc), unlock bootloader via
Code:
fastboot oem unlock 0x"(code from here https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/)". You can find IMEI in the little latch above micro sd card slot/
3. Flash Via fastboot Kernel Flash DooMLord Method (I flashed stock system first viafastboot from xperifirm, not sure if necessary)
4. Restart phone, press Vol down repeatedly
Fastboot mode with Bootloader Unlock Allow: No
Hi, I don't know, but what I'm going to tell you is a bit strange, I don't know if someone happened to it, it turns out that I have a sony xperia m, model: c1905 and it turns out that the bootloader is locked in: no, but so for stumbling probe in fastboot mode and if you let me in the blue light turns on,It was from vodafone, but it is free, because it does not put any number in what is SIM LOCK, but if it puts an X but not numbers, we are going to be released, but it has surprised me and even more, that it lets me enter fastboot mode With the bootloader unlock allowed: no, then it is to know from there, what should I do,If now, I should unlock it with the code of the bootloader unlocking sony page or I don't know, that's why I ask before doing anything, and then without knowing what I do, load my phone, I would be grateful for this if there is any solution , and if someone else has happened this strange, thanks and regards

oem unlocking dissapeared. model sm-A105GS/DS After attempted flash. (SOLVED)

the idea is to simply deggogle my a10. i found a few videos on how to do it. however i took the liberty of making a note of the base build number and after searching the internet, i found a firmware farchive that contained several md5 files. i figured i may need this in case anything went wrong.
so i went into settings and developer mode, turned on unlocking oem and usb debugging and attempted to flash the phone by booting into rescue mode (power off phone then power on while holding the volume up button) then selecting boot into bootlader from the menu before using a toll called odin on my pc, which given the threads i've seen on here, most of you are aware odin. i tried to flash the tar file reccomended on the site. odin reported failure. so without rebooting i flashed the firmware that matched my phone my selcting the respective md5 files and telling odin to do it. it reported neither success nor failure but gave a message of something like cs select. i have no idea what that means. however on rebooting the phone it booted fine. no errors or anything, just a completely reset phone. I like to add that this is not may main phone as i am a newbie on this area and wouldn't be so reckless as to experiment on my main phone. hower there is an app on there now called lazade which i beleiv is a shopping app based in the asian continent which isn't where i'm from. i unlocked developer mode once again as it had reset and found that the unlock oem option is missing. is it becasuse of the firmware i burned on it and to i need to reburn another? or is ther another way to get it back?
the baseband version is a105gdxu8cvg2
android 11
one ui 3.1
Your post isn't very clear....have you been able to unlock your bootloader?
The OEM Unlock toggle often disappears if 1) the bootloader is already unlocked, or 2) the system has not yet verified whether OEM unlocking is allowed. This is most likely not a firmware issue.

Assuming your bootloader is already unlocked, here is the TWRP thread for your device., which you probably could have found by searching. Instructions for flashing are in that thread. And here is the LineageOS 19.x GSI thread.
If you haven't unlocked your bootloader yet, that's your first step. Some devices are not bootloader unlockable.

When you're in download mode, you should see OEM LOCK among the text in the upper right of the screen. If this says ON, your bootloader is locked.

oem lock onu1)
looks like it's on. how do i disable it for this phone?
Turn the phone completely off, and leave it off for a few minutes. Then, while holding both Volume buttons together, plug in the USB cable. The device should start in Download mode. Hold Volume + until the bootloader unlock screen appears, then follow the prompt to unlock your bootloader. This will wipe data.

development, i noticed the wifi wasn't turned on. i turned it on the went into the development mode. unlock oem was there and ticked
so i did what you said again, this time the option for unlocking oem in download was present. i followed the instructions. it booted and came telling me the oem is unlocked and won't be able to verify the intergrty of the os. now it's doing a reset. i think we got here. what next? you you said twrp?

ADB only works in Android or in recovery mode. Samsung devices don't have a fastboot mode.

Yep. Since you don't already have TWRP installed, follow "Method 2" in the thread I linked.

yep it does. i had a little bit of trouble between installing the first and second file. it kept reporting a corrupt operating system but i noteiced it cycled a reboot wo i held hte power and volume up buttons together when it cycled. this allowed me into rescue mode. from there i was able to power down the phone so i could reboot it back into download mode then upload the rescue file contained in the zip file mentioned. after that it booted ok but keeps claiming that the operating system isn''t offician but then boots into android ok. i expect installing the disable_drm_very app wil fix that. then i can try installign a new os.
but that's for tomorrow
